• Text shaping
  https://blogs.gnome.org/mclasen/2019/07/27/more-text-rendering-updates/
  https://gitlab.gnome.org/GNOME/pango/issues/386
  https://developer.gnome.org/pango/stable/pango-Markup.html

  A fantastic update to the Pango library brings us closer to true beautiful typography. Bitmap font support is dropped but I guess for those you don't really need Pango to begin with.

• xargs, the one we fear
  https://medium.com/@aarontharris/xargs-wtf-34d2618286b7

  There are only specific cases where I would personally use xargs, usually something similar to what's described in this post. Do you have other usages? Let us know.

• Containers, yes, again
  https://tutorials.ubuntu.com/tutorial/introduction-to-lxd-projects

  LXD is a cool management platform. I'm still new to all the virtualisation possibilities but I'm looking forward to trying some soon for the easy handling of future projects. I'll probably go for docker though.

• Resuming ZFS send
  https://oshogbo.vexillium.org/blog/66/

  ZFS is one amazing piece of software, and now it's even more flexible.

• What to do when it's too large
  http://moo.nac.uci.edu/~hjm/HOWTO_move_data.html

  In continuation with the previous link, how do you transfer large chunks of data on the wire. This is the goto article when it comes to transfer, it's more than complete and covers everything you need to know. We mentioned a lot of the tools in the newsletter before.

• Google data sharing protocol
  https://github.com/google/data-transfer-project/blob/master/Documentation/Overview.md

  "Users should be able to easily transfer their data directly between online service providers." So are we finally going to get the real "digital identity" we've been waiting for, the one we own? Refer back to everything we've said about digital identity previously in the archive.

• Streams and terminals
  https://lucasfcosta.com/2019/04/07/streams-introduction.html

  We've seen this blog before in "Terminal prevalence" of 119, the author is continuing on the quest of bringing knowledge about terminals. It's well done, quick and straight to the point, explanation of what terminal emulators are in relation to streams.

• Legacy of war
  https://jacoby.github.io/computer_history/2018/02/09/the-legacy-of-the-unix-wars-is-still-around-us.html

  Recalling and telling tales of the Unix war through a bug that happened today. I like wise old words.

• Making the old work again
  https://tiffnix.com/blog/2014/10/19/refactoring-legacy.html

  Who's reading this newsletter and feeling they are in the same position as the author? Well, it's not easy to maintain code over decades, through unexpected changes. This field fascinates me, how can you design a software so that it's resilient against time. Also give this game a try, it's terminal friendly!

• Portability of Tar
  https://invisible-island.net/autoconf/portability-tar.html

  This isn't a new article, far from it, but I hadn't really taken the time to read it properly before. Reading through you can really grasp how standardization is important across platform, you can refer to the Unix war article above.

• Haveged
  https://wiki.archlinux.org/index.php/Haveged
  https://issihosts.com/haveged/

  In continuation with all the randomness talk we've had. A must have for virtual machines and docker.

• Keys and truststores
  https://nixers.net/showthread.php?tid=2269

  A thread on the forums of some weeks ago about the hodgepodge of keys and certificates on your Unix machine.

• Low level is beautiful, don't be afraid
  https://www.youtube.com/watch?v=Z5JC9Ve1sfI
  http://yosefk.com/blog/low-level-is-easy.html

  In relation with most of the links in this newsletter, we are discussing the mental burden of understanding software, at every level and over time. Those links emphasize on the low-level part.

Thoughts

HE is lucky who realizes that "luck" is the point where preparation meets opportunity.

This is going to be the last newsletter in quite a while. I'm going to take a pause and free up time to study software architecture, a topic that captivates me. I'll foster my love of diagrams explaning complex software stacks.

vermaden will shortly send an email to the currently subscribed readers of this newsletter with a link to his to those who are interested.

I hope you have a wonderful week!

Unix

• A series on text rendering on Linux
  https://mrandri19.github.io/2019/07/18/modern-text-rendering-linux-ep1.html

  Just reading the title and I'm already a fan. I've been pushing this topic a lot, "Font rendering" in 118, Unicode in 116, "Another one about fonts" in 107, "Font rendering" in 105, "Designing a font" in 102, "Again in the world of typography" in 98, "Xft but for xcb" in 91, "Font shaping" in 82, "Choosing the right typography" of 74, "Unicode" in 72, "Chinese fonts" in 71, "More on typography" in issue 63, "Font editing done good" in 56, the "Xero's Weekly Ricing Tips" of issue 34, "Fonts on Unix" in 12, "The best font dialogs" in 11.

• Arduino typewriters
  https://makezine.com/2015/07/01/48-solenoids-transform-1960s-typewriter-computer-printer/
  https://blog.arduino.cc/2017/07/05/hack-an-old-typewriter-with-arduino-for-digital-input/

  Bring back life by combining mechanics with electronics.

• Rundown on vim history
  https://begriffs.com/posts/2019-07-19-history-use-vim.html

  A really good quick overview of the history of vim and then a dive into multiple features and usage of vim.

• Hey, look here, I know the hidden secret truth
  http://www.ceri.memphis.edu/people/smalley/ESCI7205_misc_files/The_truth_about_Unix_cleaned.pdf

  1981, that was quite a while ago and the paper is dated. There are some good points in it, mostly about the system not being so straight forward.

• The evil gnome
  https://www.intezer.com/blog-evilgnome-rare-malware-spying-on-linux-desktop-users/

  Targeting the Gnome desktop on Linux is a pretty specific endeavour. It's the default on RedHat so that may be lucrative for this group. I'm not sure how difficult it is to attack a highly skilled group of sysadmin via phishing.

• Audio on NetBSD
  https://netbsd.org/gallery/presentations/nia/netbsd-audio/

  A list of changes and great work done to use the native audio API of NetBSD instead of wrappers over wrappers.

• Ansible or Puppet
  https://www.upguard.com/articles/ansible-puppet
  https://www.simplilearn.com/ansible-vs-puppet-the-key-differences-to-know-article
  https://www.devopsgroup.com/blog/puppet-vs-ansible/

  Those are not really fancy links, this is a common question asked in the world of sysop, deployment management, configuration management. If you've ever worked with a cluster of nodes you need to look into those, and also PaaS and IaaS.

• What better way to learn about syscall
  http://notes.eatonphil.com/emulator-basics-system-calls.html

  If you don't know how a technology works, then try to check underneath, if that doesn't help then try to implement it yourself.

• Letting the compiler optimize
  https://lwn.net/SubscriberLink/793253/6ff74ecfb804c410/
  http://www2.rdrop.com/users/paulmck/RCU/whatisRCU.html

  Compiler optimization is tricky, heck, those cases make me think of the gamma rays flipping bits. But compilers are allowed according to the specs, which I've just skimmed through. RCU, read-copy,update, is magic too. The world of the kernel space is full of super optimizations.

• Random (2)
  https://ericlippert.com/2019/01/31/fixing-random-part-1/
  https://ericlippert.com/2019/02/04/fixing-random-part-2/

  Following the previous week "Random oh random" of 132, we keep the talk about seeds and what are the best practices.

• Signing a wobbly format
  https://latacora.micro.blog/2019/07/24/how-not-to.html

  I've dealt with something similar not so long ago, but in XML... Oh the horror, it's the one mentioned in the post. It's tricky to do right.

• If you're curious
  https://waitbutwhy.com/
  https://what-if.xkcd.com/

  Not Unix but definitely worth sharing. Two very popular blog about asking questions and doing research to find how deep it can go.

• Don't attack my storage
  https://threatpost.com/linux-ransomware-nas-servers/146441/

  I love how it's written as a true fight.

• Gnu Parallel examples
  https://vfoley.xyz/parallel/

  For the people who have 40 cores to spare, it sure is going to speed things up. For me, I'm not really sure.

• Making those object cli compatible
  https://codeclimate.com/blog/your-objects-the-unix-way/

  This is simple good software practice, I'm not sure it's even Unix specific. Prioritize simplicity.

• If you've never done that do it now
  https://ablagoev.github.io/linux/adventures/commands/2017/02/19/adventures-in-usr-bin.html

  A lot of things get installed as dependencies sometimes, it's hard to track down what does what. In this article you'll find, maybe, some tools you haven't seen before. I personally hadn't heard of chrt.

• The conundrum of Linux to Windows
  https://medium.com/microsoft-open-source-stories/when-linux-came-to-windows-204cf9abb3d6

  The journey to do this weird feat of porting Linux to Windows. To be honest I'm not sure where this would lead, it's been a while since the release now. Does it turn people that are working on Windows to like Linux more and try it, does it make people that prefer Linux working on Windows bear with it and not complain as much. Maybe both, we'll see how it develops.

• reproducible build of FF

• Playing with Linux in userspace
  https://christine.website/blog/howto-usermode-linux-2019-07-07

  I had no idea this existed before today. Kudos to the author for that super cool post and setup. The knowledge of old arcane tools left me breathless.

• Fantasy development
  https://people.kernel.org/monsieuricon/patches-carved-into-developer-sigchains

  What would happen in a world of decentralize and secure development, everything signed, easily shareable. It's convenient, maybe the idea will take off, maybe not.

• What's an idempotent script and how to make shell script that way https://arslan.io/2019/07/03/how-to-write-idempotent-bash-scripts/

  Those are certainly tips to remember next time you write a script that could possibly, and most probably, fail in the middle and be restarted.

• When you want to be a detective
  https://bsdimp.blogspot.com/2019/07/the-pdp-7-where-unix-began.html

  Pretty impressive to go to such extent to recollect history pieces, stitching them together and construct a possible lead to a question maybe no one thought of asking.

• Will X11 get deprecated?
  https://utcc.utoronto.ca/%7Ecks/space/blog/unix/XDeathwatchStarts

  Might be a single developer talking, or it might be a way to show the world a stance on the topic. Regardless, we'll see what happens.

• Jumping on the Rust train
  https://nora.codes/tutorial/speedy-desktop-apps-with-gtk-and-rust/

  As far as I'm concerned I have yet to try it. Sick of fat Electron apps, then this tutorial should be very enticing.

• Having troubles getting used to your Windows machine sub-linuxy system?
  https://timvisee.com/blog/fix-windows-terminals-use-linux-terminal/
  https://www.analyticsindiamag.com/linux-vs-windows-which-is-the-best-os-for-data-scientists/

  A post about setting up your favorite terminal on through Windows Linux sub-system and another, not so fancy, sort of listicle.

• Gnuplot step by step initiation https://raymii.org/s/tutorials/GNUplot_tips_for_nice_looking_charts_from_a_CSV_file.html

  It's kind of hard to use gnuplot compared to graph editors found in WYSIWYG editors. This is the kind of tutorial that let you build a script that you can rely on for automation, unlike with fancy editors.

• But I already wake up at that time
  https://www.farfetchtechblog.com/en/blog/post/nobody-wants-to-be-woken-up-at-4-am/
  https://www.weave.works/blog/the-red-method-key-metrics-for-microservices-architecture/

  Not necessarily related to Unix but to sysadmin in general. Monitoring is a wide topic see also "Log navigation" in 129 and "Monitoring" in issue 108.

• We didn't have the week in the TTY
  https://www.linuxjournal.com/content/without-gui-how-live-entirely-terminal

  I was out of the picture in June, maybe we should reschule it for this month. What do you say, bump the previous thread on the forums with your opinion (https://nixers.net/showthread.php?tid=2205).

• Branch prediction
  https://danluu.com/branch-prediction/

  An overview of the algorithm used for branch prediction in the 90s.

• Random oh random
  https://flak.tedunangst.com/post/random-in-the-wild
  https://lwn.net/Articles/686033/
  https://blog.demofox.org/2019/05/25/generating-random-numbers-from-a-specific-distribution-with-the-metropolis-algorithm-mcmc/
  http://qrng.anu.edu.au/

  That first article is epic, a must read. The sort of stuffs you can come up with to create pseudo-random algorithms is insane. The other posts are related to randomness in general, feeding you the seeds you need for this week. That last blog has a lot of articles related to all kinds of RNGs.

• All you need about eBPF
  https://qmonnet.github.io/whirl-offload/2016/09/01/dive-into-bpf/

  I'm new to bpf and started going through the resources provided here. It's a real gold mine.

• Trusted BGP
  https://tools.ietf.org/html/rfc6480
  https://medium.com/@jobsnijders/a-proposal-for-a-new-rpki-validator-openbsd-rpki-client-1-15b74e7a3f65
  https://github.com/openbsd/src/tree/master/usr.sbin/rpki-client
  https://marc.info/?l=openbsd-cvs&m=156078373619043&w=2

  Validating route statements, origin validation, RPKI is fascinating. I love how we're moving in a direction of secure by default, at all layers, now IP included. Great job OpenBSD, making the internet, and by consequence, the world a better place.

• Networking from the ground up
  https://www.privateinternetaccess.com/blog/2016/01/linux-networking-stack-from-the-ground-up-part-1/
  https://www.privateinternetaccess.com/blog/2016/01/linux-networking-stack-from-the-ground-up-part-2/

  https://www.privateinternetaccess.com/blog/2016/01/linux-networking-stack-from-the-ground-up-part-4/
  https://www.privateinternetaccess.com/blog/2016/02/linux-networking-stack-from-the-ground-up-part-4-2/

  We've seen this blog in issue 63 "Privacy, confidentiality, and anonymity", this time we're diving into the network stack. A really insightful series, plenty of information I had no idea about.

• Replace ZFS disk
  https://imil.net/blog/2019/07/02/Replacing-a-silently-failing-disk-in-a-ZFS-pool/

  Probably the most humane way to explain how to replace a disk in a ZFS pool. A well written tutorial.

• A debug story
  https://rkeene.org/projects/info/wiki/173

  Yet another debug story. Oh how it's funny when it ends with "it magically started working again".

• Waypipe
  https://mstoeckl.com/notes/gsoc/blog.html
  https://gitlab.freedesktop.org/mstoeckl/waypipe/

  Looks like it is quite tricky to implement a message and data passing/proxy way between Wayland client and compositor such that it can be used over sockets. Hint: Read from bottom up.

• IRC is fine
  https://drewdevault.com//2019/07/01/Absence-of-features-in-IRC.html

  Also from someone contributing heavily to Wayland but unrelated. Ever used IRC? If you're reading this email then you must have. Do you agree with what's being said in this post?

Unix

• Slow computer optimizations
  http://www.akitaonrails.com/2017/01/17/optimizing-linux-for-slow-computers

  A reminder of all our talk about real time, what it means for the desktop users. There are lots of great little tricks in this article, they'd need more in depth explanation but it suffices for the job. It's my first time hearing of Ananicy.

• Desktop environment research
  https://desktop.institute/

  Still a WIP but I'm highly looking forward to what this could lead to. I know a lot of my readers could actually help by providing some content to the author of the website.

• Another OS for phones
  https://postmarketos.org/blog/2019/06/23/two-years/

  You caught me at "Wouldn't it be great if you could take any obsolete smartphone from the past ten years and replace its outdated and insecure software with a maintained, modular free software stack". This sounds promising.

• The CLI as a relational DB
  https://spin.atomicobject.com/2019/06/16/unix-cli-relational-database/

  It's the usual cli as a data manipulation tool talk but taken from the perspective and mapping with relational DB. Though there's a little misinterpretation of what sum(1) does.

• Groups in namespaces
  http://ifeanyi.co/posts/linux-namespaces-part-1/

  A typical "build your own container to learn how they are made" type of article. This one emphasizes on cgroups and their utility.

• Eyecandy for ssh-askpass
  https://adi.tilde.institute/Customize%20ssh-askpass%281%29%27s%20appearance.html

  I'm a fan of the old school blocky GUI. They are clean in my opinion. But if you want something more minimal you can get inspired by the config shared here.

• File creation time
  https://www.anmolsarma.in/post/linux-file-creation-time/

  It's the normal writeup about why there's no creation time on Linux. The whole story behind why it took so much to add changes to the kernel, the filesystems, and libc.

• libc using LLVM
  http://lists.llvm.org/pipermail/llvm-dev/2019-June/133308.html
  https://www.phoronix.com/scan.php?page=news_item&px=Google-New-LLVM-Libc-Thoughts

  A team at Google wants to create their own libc, as an LLVM libc. Lots of ups in downs in the talk. I'm personally not sure it's a good idea, there are a lot of toy project libc that gets thrown away or live as historical monuments.

• Demystifying firmware linker scripts
  https://interrupt.memfault.com/blog/how-to-write-linker-scripts-for-firmware

  Ever wondered what those linkers scripts with their weird syntaxes were about, this is for you. It's not a full coverage of the topic but it's a start, extra cool in my opinion, especially when speaking of embedded solutions.

• Recovering corrupted zip files
  https://www.7-zip.org/recover.html

  Oh the world of formats and specifications. Want to fix your 7z archive manually, then here's the guide.

• Deprecating a.out
  https://www.linuxjournal.com/content/deprecating-aout-binaries

  This is something we've already seen in "Removing a.out" of issue 118. This post adds the background story behind the change, the intricacies and discussions happening.

• Fresh administrators
  https://www.linuxforfreshers.com/

  A blog dedicated to learning all sorts of topics for Linux administration. Some topics are super basic while others are kind of advanced. Take a look at the sidebar and see if something interests you.

Just go back from vacations.
This newsletter was super hard to put together but I did it.

Unix

• Why does it have its current name
  https://wiki.debian.org/WhyTheName

  A little follow up on the pronunciation guide from last issue (129). Linguistic is important ladies and gentlemen, you got to get your things right. You'd be surprised by some of the names, most acronyms, most cryptic inside jokes, oh Unix.

• Files
  https://linuxmeerkat.wordpress.com/2011/12/02/file-descriptors-explained/
  https://www.devever.net/~hl/objectworld
  https://eklitzke.org/efficient-file-copying-on-linux
  https://www.networkworld.com/article/2931534/what-are-unix-swap-swp-files.html
  https://www.networkworld.com/article/2704805/unix---when-pipes-get-names.html
  http://events17.linuxfoundation.org/sites/events/files/slides/fd_0.pdf

  Getting sick already of always discussing about files, don't be because there's much more content to come. From discussions about file descriptors, to what a nexus is, to filesystem and HDD readahead cache buffer, to swap files, and much more.

• File manip
  https://medium.com/@jmsmistral/on-transposing-data-884a04a8c1bf

  Data science fans will enjoy this article. It has a good rundown on all the solutions to a specific issue.

• Chroot history
  https://utcc.utoronto.ca/~cks/space/blog/unix/ChrootHistory https://utcc.utoronto.ca/~cks/space/blog/unix/ChrootHistory?showcomments#comments
  https://lwn.net/Articles/252794/

  Quite an old syscall that has arguably changed its original meaning and purpose over time. There's some argument that the security aspect of it was taken in consideration to begin with, others argue that it wasn't the point.

• The design of find
  http://doc.cat-v.org/unix/find-history

  Following specs to the letter without discussion is one skill of its own. Until you can't change anything about it years later.

• Graduating from vim school
  https://www.hillelwayne.com/post/intermediate-vim/

  I love how the author splits the article between purist vim users and exobrains vim users. Lots of great and useful content in there, I personally know that there's 2 tricks I'm going to start using from now on.

• Still on the quest of DE/WM
  https://bitcannon.net/post/pro-desktop/
  https://www.cdevn.com/my-os/
  https://hookrace.net/blog/linux-desktop-setup/
  https://github.com/mikadosoftware/workstation

  Everyone have their opinion about desktop environments, there's discussion about the lack in some sense and the advantages in others. One thing that is recurrent these days is using docker/immutable/nixOS as a base. Reproducibility is key.

• GNOME profiling
  https://feaneron.com/2019/05/31/profiling-gnome-shell/

  An example of profiling Gnome shell using sysprof 3. This is cool, similar to the profiling tool found in popular web browsers.

• Package management done the right way
  https://www.getlazarus.org/apps/makedeb/
  https://github.com/ceejbot/economics-of-package-management/blob/master/essay.md

  I'd like to see a command line version of the makedeb program, it's simple enough that it doesn't require a GUI. That second post is about package management intermixed with ownership and money making.

• Slowing down your internet
  https://jvns.ca/blog/2017/04/01/slow-down-your-internet-with-tc/

  That's what the bloated websites of today should try. Some of us are on awfully slow connections. Also, nice to remind us of HTTP2.

• PCI devices on Linux
  https://codeofconnor.com/2019/06/01/how-the-linux-kernel-detects-pci-devices-and-pairs-them-with-their-drivers/

  A walkthrough some stacktrace to understand how the Linux kernel decides which device is handled by which driver.

• Asking the time server
  http://seriot.ch/ntp.php
  http://yellerapp.com/posts/2015-01-12-the-worst-server-setup-you-can-make.html

  Again, a continuation of the time and date series. A small command line implementation of an ntp client to fetch time and a recommendation for server admins.

• Tech veganism
  https://nolanlawson.com/2019/05/31/tech-veganism/

  Here's a new term for you, like it or not.

• No more OS
  http://www.fixup.fi/misc/usenix-login-2015/login_oct15_02_kantee.pdf

  Is the OS layer deprecated? Can't we delegate the role to the hardware instead of having drivers? Why are we stuck?

• pronunciation guide

  When in doubt refer to this guide.

• Getting pledge on Linux
  https://notabug.org/rain1/linux-seccomp-pledge/

  With all this talk about pledge on OpenBSD some people want to get it on Linux. Good news, it's already there, not the same but close enough.

• Libranet autobio

  https://www.linuxjournal.com/article/8290

  Taking part in a project, investing yourself in it, to then see it crumble slowly or quickly. It's simply life, things happen, you gotta move on and learn from the experience.

  Why not write a new shell, we've seen in "A new shell, why?" of issue 87 and "the elvish shell" in 100 that this could be a fun endeavour. So take a look at those brand new ones, there are so many more online but those are the ones getting the most traction. Along with those links you'll find other shell related content.

  We've been sharing a lot of beginner's guides, back to square one type of articles. Maybe it would be a good idea to gather them in a list that could be easily given to someone starting out so that they can go through it and slowly learn.

  https://freethreads.net/2019/05/27/internals-of-linux-process-signals-2/
  http://www.linuxprogrammingblog.com/all-about-linux-signals?page=show

  I like the way this website is made, compressed and summarized explanation. Kind of like cheat sheet for explanations, the sort you'd take before an exam. The next one is the complete opposite, I used it for the research of the Unix signals podcast.

• Scheduling optimizations
  http://www.ece.ubc.ca/~sasha/papers/eurosys16-final29.pdf

  NUMA, if you've never heard about this acronym then welcome to the world of big machines. The bug described in this paper (You can skim a bit if you're already aware of scheduling and go directly to section 3) reminds us of how tricky scheduling is and how depending on the hardware architecture it can be.

  https://news.ntppool.org/2012/06/more-servers-please/

  Back with the leap second issue we've seen in "Keeping time and date". The discussion for leap second abolishment didn't got so well. And we still lack some public utility servers.

• FUSE and FUSE
  http://engineering.facile.it/write-filesystem-fuse/
  https://www.tagsistant.net
  https://github.com/johang/btfs
  https://github.com/immobiliare/sfs

  FUSE can be so much fun, see "I Made MPD Index SoundCloud." and "DungeonFS" in 78. "Semantic filesystem for Linux, with relation reasoner, autotagging plugins and a deduplication service" that sounds better than tagsistant. Those are all fine examples of usage of FUSE.

• Files are hard
  http://danluu.com/file-consistency/

  In relation with the previous links, it's tricky to keep file consistency over a long period of time. Read up to discover why, a bit dated though, but it makes you think about all those very Unixy tools that only rely on files, they may suffer from this condition on the long run, so beware!

• Extreme programming
  https://blog.dima23.de/post/2018-12-11-tmux-pair-programming/

  I once thought, when picking up a book, that extreme programming what about cool skateboard tricks but with computers, I was wrong but gladly so. Pair programming is fun and a good learning experience when done right.

• Profiling, server management, demo gods
  http://poormansprofiler.org
  https://sysdig.com/blog/50-shades-of-system-calls/
  https://www.usenix.org/conference/lisa13/technical-sessions/presentation/merlin

  Those three links are legendary. From building your own profiler using gdb, to sysdig mega demo, to a live upgrade of thousands of servers.

• Log navigation
  https://github.com/tstack/lnav
  http://goaccess.io

  Next up after the links of above, pale in comparison, two cool fancy log and weblog navigator and display. They should help in debugging weird issues, or at least monitoring. See also "Monitoring" in issue 108.

• Guide to linker
  http://www.lurklurk.org/linkers/linkers.html

  Still on the train with ELF, PLT, and GOT, we continue or probably should've started with this article. A well done and approachable summary of what linking is about, one of my recommended reading on the topic.

• Shared Memory
  http://blog.httrack.com/blog/2014/04/05/a-story-of-realloc-and-laziness/
  https://lwn.net/SubscriberLink/789153/b21b94232f0c84fc/

  Read the section above before this one, and maybe also the malloc implementation links in the newsletter archive. We first take a look at an inspection of a specific use of memory allocation and then check what's new (or could be new) in Linux memory sharing between processes.

• The Portable C Library book and others available online
  https://archive.org/details/ThePortableCLibrary_May75/page/n16
  https://archive.org/details/ADescriptionOfTheUNIXFileSystem_Sept75/page/n13
  https://archive.org/details/@swieros

  They are so fantastically well scanned that it feels like having them in front of you.

• X11 stack
  http://www.theresistornetwork.com/2013/12/a-testament-to-x11-backwards.html
  https://arstechnica.com/information-technology/2011/03/the-linux-graphics-stack-from-x-to-wayland/
  https://github.com/jcs/xbanish

  X11 is a fun piece of software, full of features, really full. Those three links are a testament of this.

• Reaching a dream environment for all
  https://ploum.net/195-the-aristocratic-desktop-part-1/
  https://ploum.net/201-the-aristocratic-desktop-part-2-home-is-desktop/
  https://ploum.net/219-the-aristocratic-desktop-part-3-there-s-no-tray-icon-in-gnome/
  https://ploum.net/kill-double-click/

  A series of articles very in line with the ideas shared in "OpenBSD laptop @ BSDCan" of 128, "Ever installed a Unix-like system for a friend who's not technie?" with the aunt in 54, "Usability" in 71, and "When will be created great desktop experience for OpenBSD." in this same issue. Building a sensible, default, basic environment for non-tech-enthusiast that only want to use the computer as a tool, this sounds easier than it actually is.

• Logical fallacies in development
  https://artur-martsinkovskyi.github.io/2018/logical-fallacies-in-programming/

  Not really Unix related, but there's some hint that could somewhat be associated to it. A straight forward list of behaviors we've most probably encountered in our day to day.

Thoughts

Software engineers live in a world of deep introspection. They spend most of the day solving complex problems, breaking problems apart and reconstructing them. Often, when they are distracted, their subconscious can make the most bizarre leaps, connecting half-baked ideas and partially solved algorithms. This can happen in the oddest of places, for example, in the shower, or cooking in the kitchen, or driving in a car.

• Scratch files for the shell

Unix

• zfs from scratch in python
  https://github.com/alcarithemad/zfsp

  An impressive feat, a pure learning experience from analysing FS structure of ZFS.

• Damn, it's irreversible
  https://sabotage-linux.github.io/blog/6/
  https://github.com/rofl0r/hardcore-utils/blob/de5a4ca/fastfind.c

  I can't remember where I've read about that technique before, the good ol' saying that you should type your filename again at the top of the file in case you loose it. However, I hadn't really tried it before, nor seen a full post about actually recovering the file manually. This sounds simple enough.

• Naming files
  https://rasmuse.github.io/i-want-to-stop-naming-files.html

  A problem we've all ran into, doing tests with something, outputting different files with different names depending on situations. You then get lost which file was used for what.

• April 2019 review of reproducible build
  https://reproducible-builds.org/reports/2019-04/

  The magic of reproducibility is on its way. Lots of projects are interested in what this implies. Lovely to see this move across so many areas.

• About the Mozilla addons outage
  https://hacks.mozilla.org/2019/05/technical-details-on-the-recent-firefox-add-on-outage/

  Oh I love this read, the PKI is so entertaining. However, it annoys me that Mozilla, an entity that is maintaining one of the most, if not the most, used CA trust DB to not be aware of their own system for signing addons and not have anyone tracking the intermediate certificate expiry (and probably all other sensitive assets), not even having the thought of what would happen when this expiry date is reached. I'll let you read for more info.

• CPU governor makes it to 5.1
  https://lwn.net/Articles/775618/

  TEO (Timer events oriented) governor made it to Linux 5.1. Predicting events to save up cpu usage is not an easy endeavour, from the benchmarks this is still a thing to try first hand before judging.

• GPL rights or no rights
  https://lkml.org/lkml/2019/5/3/698
  https://lkml.org/lkml/2019/5/4/334

  A huge discussion about the revocability of free licenses when those were not explicitly given to the licensee in exchange of some goods. Legal rights differ dependong on the country, the talk is very USA centered so keep this in mind.

• Polkit and dbus
  https://www.freedesktop.org/software/polkit/docs/latest/polkit-architecture.png
  http://smcv.pseudorandom.co.uk/2015/why_polkit/
  https://www.freedesktop.org/software/polkit/docs/latest/polkit.8.html

  https://www.freedesktop.org/software/systemd/man/systemd-logind.service.html
  https://www.freedesktop.org/wiki/Software/systemd/writing-display-managers/

  Lots of documentation about polkit and logind, brace yourself for lots of dbus ipc.

• Without javascript
  https://an3223.github.io/Living-without-the-modern-browser/

  The web has become so prevalent today it's unescapable. Take a lesson from this guy for our next week in the TTY that is coming soon, probably next month.

• Did you know about this feature
  https://www.anmolsarma.in/post/bash-net-redirections/

  That's a nice feature, sort of like a simpler nc you can have for quick debugging.

• VCF East 2019 interview with Brian Kernighan and Ken Thompson
  https://www.youtube.com/watch?v=EY6q5dv_B-o

  A lot of things are happenstance, listen to Ken recall his days at Bell Labs.

  Different blogs and articles about open source. A partnership between ETSI and the Linux foundation to have open source collaboration on network automation.

• Recalling Unix
  https://www.linuxjournal.com/content/back-day-unix-minix-and-linux
  https://www.linuxjournal.com/content/why-linux-spelled-incorrectly

  Fun recollection of first encounters with Unix-like operating systems followed by the most ridiculous argument I've ever read "I don't like it so I'll find some reasons to disavow it, whatever it is", the comments are priceless. I advice, if you feel a bit frustrated then avoid both articles, they're pretty basic.

• Linux on 8-bit microcontroller
  http://dmitry.gr/?r=05.Projects&proj=07.%20Linux%20on%208bit

  This is a repost of "Following through with the low level hacks" in 52, just felt like revisiting it because I recently got into the world of embedded devices and microcontroller. See also "Reducing/Shrinking the Linux kernel" in 66.

• Getting closer to good hidpi
  https://pointieststick.com/2019/04/28/kde-usability-productivity-week-68/

  The KDE UX team has been consistently pushing those posts every week for more than a year now. The consistency is fantastic for multiple reasons, it's a message to the world that things are moving and getting better, everyone can comment about possible changes that could be made so full fledge agile in play here, it's a message to possible devs that want to hop in and want to know what to work on, and finally it keeps the motivation for the team itself going.

• GPU card for chromebook
  https://www.androidcentral.com/will-somebody-make-me-chromebook-real-graphics-card

  Chromebooks used to be that extremely light and low hardware specs, cheap laptop, thin client. Now you can find chromebooks that are more powerful than laptops, can't we stop calling them chromebooks then?

• Misleading bug
  https://news.sherlock.stanford.edu/posts/when-setting-an-environment-variable-gives-you-a-40-x-speedup
  https://old.reddit.com/r/linux/comments/bhvwvl/when_setting_an_environment_variable_gives_you_a/

  You got to remove the fancy eye candies if you want your command line to be fast. My solution would've been way simpler than anything that was proposed in the above, just command ls instead, skip all aliases.

• Less
  https://www.lifewire.com/what-to-know-less-command-4051972
  https://ss64.com/bash/less.html

  Know your pager well, it's powerful, it has lots of features you might not know about.

• Shell and more shell madness
  http://250bpm.com/blog:153
  https://0x46.net/thoughts/2019/04/27/piping-curl-to-shell/
  http://cdaniels.net/shell_music.html

  The true hardcore Unix philosophy, having all the pieces of the programming language be represented as a file! Plus, the usual "please don't paste commands from the interwebs into your terminal blindly". The freaky one I was not aware of is the "Partial content returned by the server". And finalizing with a touch of musicality.

• Memsetting
  https://www.anmolsarma.in/post/stop-struct-memset/
  https://news.ycombinator.com/item?id=19766930
  https://lobste.rs/s/7aqidd/stop_memsetting_structures

  You probably have already seen it in tech news, I'll highlight the post here too. I like it when someone posts such "X considered harmful" or "Stop doing X" and then the flaming train falls upon the web.

• IPSec
  https://www.elastichosts.com/blog/linux-l2tpipsec-vpn-server/
  https://www.ibm.com/developerworks/library/l-ipsec/index.html

  Setting up a VPN isn't that hard, but the is it needed for your case. Is it enough to ssh and port forward instead? Isn't it faster according to "Tunneling/syncing data between machines securely" in 51?

• rdist(1)
  https://high5.nl/gist/rdist.html

  We discussed that topic a lot, distributing files over machines, so here's another take on it.

• IMSI catcher
  https://harrisonsand.com/imsi-catcher/

  Not really Unixy but it runs on Unix-like OS. Some of the equipment is hard to get your hands on in parts of the world but other than that it's nifty.

  "Line of death", basically a bug because the UI is misleading. All of that to save screen estate.

  I like those articles about digging into old sources, someone replying with clarifications, the research intensifying, and in the end more truth coming out. It might confuse some, they might prefer a nicely polished post, but personally, I the intrigue in those keeps me reading. It's like uncovering knowledge.

  https://sdtimes.com/softwaredev/the-linux-foundation-launches-new-project-to-enable-linux-in-safety-critical-applications/

  Oh we talked a lot about mission critical Unix-like OS, real-time OS, during our Keeping time and date series. Well, here's a new project that was launched called elisa (Enabling Linux in Safety Application), from the look of it this seems like a standardisation process with a set of tool to build a safety-critical application meeting specific requirements.

• All those X configurations
  https://nixers.net/showthread.php?tid=2271

  So many dot files for different things, it's confusing. I've tried to compact some research into this post to make things more understandable. Maybe it does the job, let me know.

• And another
  http://zge.us.to/txt/unix-harmful.html

  Unix got fundings because it was good at text editing, it moved in new directions since then. How does this relate to Electron apps these days? "The fact that we need to layer abstraction upon abstractions says more about what we see the need to abstract from than where we are abstracting towards." An interesting point of view on the topic, maybe you agree, maybe you don't.

• Got and issue with sudo
  https://fosspost.org/opinions/sudo-asking-hiding-password

  This may seem like a meaningless issue to most of us (there's a vote button at the end of the article). It's a genuine point but I just don't see non-technical users spending time in their terminal typing commands as root... That's not a great combination there. Maybe display something not related to the count, anything that's a feedback, maybe a single character that changes at every key you enter.

• File history
  https://github.com/xorhash/fh

  An interesting take at building incremental and browsable diffs between files. It's quick to run, easy to get, portable. Overall, a cool project. Not sure I'll use it, but still cool.

• Are we there yet, are we there yet, where's my desktop year
  https://www.slashgear.com/what-the-linux-desktop-must-have-to-become-mainstream-09572504/
  https://funnelfiasco.com/blog/2019/04/22/the-linux-desktop-is-not-in-trouble/
  https://robey.lag.net/2019/04/21/darter-pro-review.html
  https://www.linuxlinks.com/foreignlanguagetools/

  In my opinion, a lot of those Linux desktop article are badly misinformed, usually relying on the disparity of choices as a valid argument. Amongst those links you can also find a review from someone jumping from an OS to another, and a list of fascinating programs to learn languages.

• Do you waddle the waddle?
  http://www.tuxmachines.org/taxonomy/term/98

  No idea what that motto means, forget it for a moment and check what Roy Schestowitz has been consistently posting for a while now. Every single day a big list of tutorials about many topics.

Unix

• Optimization, testability, and bug handling
  http://akaptur.com/blog/2017/11/12/love-your-bugs/
  https://microservices-on-my-mind.blogspot.com/2019/04/break-functional-and-orchestration.html?m=1
  http://carlos.bueno.org/optimization/

  Behind every bug there's a story, a learning experience. Bitrots, if you hear about them once, you can't forget them. Architecture issues, that's always something that morphs through time however we can apply some of the Unix philosophy to it. And finally a small book about optimization.

• Persistent memory 3
  https://www.linuxjournal.com/content/support-persistent-memory

  Follow up with "DAX on Linux" of 115 and "NOVA fs" in 114. I like where things are going, hopefully in the future we'll take advantage of those even more.

• glibc and DNS

  "I'd love to see a foundation bring together the Linux desktop community and have them hammer out out a common desktop for everyone" Isn't that what the freedesktop organization is about? A fun discussion, an old topic.

Thoughts

https://jamesclear.com/deliberate-practice-theory

I was dumbfounded when I heard about this concept in the first link of this issue. Not because I didn't know about it but because it's something I'm doing instinctively, naturally. I couldn't even imagine having to write an article about it. And having it as a concept means that some people out there are not benefiting from this simple thing. So here we go, be it obvious to you or not.

Unix

• Power UNIX
  https://www.youtube.com/watch?v=7uwW20odwEk

  A quick overview/tutorial about interacting with Unix systems. It even has the cliché fork jokes and zombies things. Highly recommended for beginners. Add it to your list of good content to spam the people that start off with Unix.

• A simple debugging story
  http://johnbokma.com/blog/2019/01/05/info-fouseragent-rendered-page.html

  I love those small blog posts tackling a simple issue. Light in nature but true to the spirit.

• Anomalies detection
  https://blog.floydhub.com/introduction-to-anomaly-detection-in-python/

  Now this is something new for me. Not really Unix but data science, it's related somehow to "Auditing" in issue 95, and all the things related to differential privacy (see issue 45).

• Network "BufferBloat"
  https://www.pauladamsmith.com/blog/2018/07/fixing-bufferbloat-on-your-home-network-with-openbsd-6.2-or-newer.html

  Congestion control is a tricky topic, it's nice to see easy solution like the one described in this post and especially when it's about setting up OpenBSD as a router. See also BBR in issue 33.

• Sega NetBSD
  https://youtu.be/ZAYgI1mfSd0

  Obviously it runs NetBSD! It's impressive that it's as easy as "playing" a GD-ROM with NetBSD, Cool work from the NetBSD team.

• Virtualization for NetBSD https://blog.netbsd.org/tnf/entry/from_zero_to_nvmm

  We started the discussion on that topic since "Emulate the right way on NetBSD" in 117. The BSDs are on the virtualization race these days. In this article gives and overview of the nvmm programming API and finishes of with its usage/patch to be used along with Qemu. Cool work.

• Gimp 2.10.10 release
  https://www.gimp.org/news/2019/04/07/gimp-2-10-10-released/

  Gimp new update is looking slick, two of the most cool improvements are the bucket filling for cartoons and the transformation tools.

• Ricing from cars to computers
  http://triosdevelopers.com/jason.eckert/blog/Entries/2019/4/7_How_ricing_shifted_from_cars_to_computers.html
  https://www.youtube.com/watch?v=Co6FePZoNgE

  Probably the best explanation to "what is ricing" that I've found. Nifty little article. Followed by a great intro to distros and gamin (See also "On the desktop" of the last issue 121).

• CheatSheet for OpenSSL
  https://github.com/trimstray/the-book-of-secret-knowledge#tool-openssl
  https://why-vi.rocks/

  The one thing that caught my attention in this page is the weird use of variables declaration right before calling the openssl command. I guess that's to plug the commands in a script and only meddle with the variables and not the specific line. I've also added another cheatsheet website that appeared in the tech news regarding vi.

• Police Officer to OpenSource
  https://www.redhat.com/en/blog/police-officer-open-source-devotee-one-mans-story

  Not your usual "how did you get acquainted with Unix" type of article. Always fun to see people from all fields finding interests in something together.

• Fast directory listing
  https://github.com/romkatv/gitstatus/blob/master/docs/listdir.md

  This is a topic I've encountered during my research for the "special files" podcast (https://venam.nixers.net/blog/unix/2017/06/04/special-files.html & https://nixers.net/showthread.php?tid=2052). A tale of optimization, maybe not portable everywhere, but super fun to read.

Thoughts

Never be satisfied, that's the way you'll fall short. See past yourself.

A quote that may seem would lead to pessimism but that I think is about the contrary. I guess it goes along with the following:

Does the tournament make sense as you keep going?

or again:

There's no such thing as perfection.

It's not the end goal that matters, it's the path, the adventure on the way, the progress, the intention. Sometimes it has boundaries, sometimes it doesn't. However if you're satisfied with the status quo you'll stop your journey short.

Unix

• Maddog history review
  https://www.youtube.com/watch?v=EZMA3Ge144U

  Sort of old (a year) but I like how maddog reviews UNIX history and his perspective on it. The informal format helps a lot. It's similar to the talk he gave at FOSDEM last February (https://fosdem.org/2019/schedule/event/keynote_fifty_years_unix/). Unfortunately filmed by the same "annoying" guy from this thread however in this video he's more laxed.

• VMS vs UNIX
  http://www3.sympatico.ca/n.rieck/docs/vms_vs_unix.html

  I like the introduction with old maps of ARPANET where you can see the machines and institutions that ran them. It then continues with a great chart comparison of VMS and UNIX both history and technology wise.

• x86 vs UNIX server
  http://mo.bi/2019/03/29/x86-versus-unix-servers/

  Another fighting round. What's better, a world of closed vendors optimizing for their operating system to fit exactly a piece of hardware or the open source Unix-like OS running on the well known x86 architecture. A fascinating article (and maybe also an indirect publicity for the Huawei server they mention at the end).

• On the desktop
  http://triosdevelopers.com/jason.eckert/blog/Entries/2019/3/4_Pop!_OS__The_first_real_Linux_desktop.html

  An opinion pieces on the old topic of "Why Linux isn't that great on the desktop". This one focuses on the state of the desktop for developers that also need to access some specific "cloud" functionalities. It ends with a push for Pop, which is another UI over Ubuntu.

• Linux Lite 4.4.
  https://betanews.com/2019/03/31/linux-lite-44/

  Remember the days of PuppyLinux, Knoppix, Slax, DSL, Tiny Core Linux, Slitaz (oh I love that one) well there's a new one in town that I discovered and it's called Linux Lite (But apparently from the look of it it doesn't seem so light). Already at its version 4.4

• Firmware on Ubuntu
  https://www.omgubuntu.co.uk/2019/03/lvfs-linux-firmware-service-success

  Distributing binary blobs is a mess, welcoming more of this, we now have a full system in place to make this easier. Hey, at least there's going to be easy download of drivers and their updates. Things might get smooth for out of the shelf installs.

• Tutorials
  http://www.ee.surrey.ac.uk/Teaching/Unix/index.html
  https://people.ischool.berkeley.edu/~kevin/unix-tutorial/toc.html

  Add those to our ever growing list of great Unix beginner tutorials.

• Neuroimaging, unix is everywhere
  https://neurohackweek.github.io/advancedunix/01-first-part/

  I just love seeing application of things, makers, especially with open resources. This link is similar to the previous one, as in it's also a tutorial/workshop on Unix basis but with an emphasis on its usage in the neuroimaging world.

• Remember the series on /proc
  http://www.linux-magazine.com/Issues/2018/217/Exploring-proc

  Yes, we've had lots of content on proc, see "top, proc, containers, and scratch" in 97, and it's not over yet. If you didn't get it the first time you'll get it the second time.

• Building a machine from scratches
  https://vermaden.wordpress.com/2019/04/03/silent-fanless-freebsd-server-redundant-backup/

  Vermaden does an excellent job at describing the steps he took to build this fanless FreeBSD server. It's impressive the length of details he go through and the benchmarks he has gathered.

  I have been thinking of writing a post on the forums about this but apparently I couldn't manage to pull it off yet. So for the moment it's going to be a series in the newsletter. All about touchpads on X11 and in Wayland compositors, how it's still tricky in 2019 to configure them properly. A reminder of issue 116 "Free Software UI", where too many configurations and possibilities are more of a burden for accessibility and usability. See also "Pushing ideas" in issue 84.

It's impressive how much you can configure and what's doable as a configuration nob from a GUI. I'd love to see a tutorial going step by step with images on how to set the touchpad properly, maybe I'll write it myself.

• Normalization of unicode
  https://github.com/begriffs/utofu
  https://withblue.ink/2019/03/11/why-you-need-to-normalize-unicode-strings.html

  We've had so many entries in the newsletter related to unicode "Unicode" in 116, "Plain text" in 57, "Unicode" in 72, even "Keeping thieves away" in 69 and "XIM and unicode" in 68. These links are simply a reminder that text is not really universal if we don't pay attention to use the right encoding everywhere.

• Microkernel and history
  https://tedium.co/2019/02/28/ibm-workplace-os-taligent-history/

  See also the link below by vermaden "Microkernel Failure". Yet another example of "worse is better", basically anything that works and is usable will prevail. You can be as idealist as you want, in the end, what works works.

• Social networking in 2011
  https://www.youtube.com/watch?v=gpB5q31pK2I

  We've come a long way since 2011, the world has moved in the direction portrayed in this talk even more. Things are serious and the discussions we've been having the past 3 years are at a peak.
  Just take a look at "What the Hell is Going On? Effects of Information Abundance." in this issue or "Keeping time and date (11)" of issue 116 to have an overview.

• The trouble with human
  http://jasonzweig.com/uploads/11.00Neuroeconomics.pdf

  An example of the issues with overrationality. The name of an author comes to mind, a fellow countryman, that specializes in statistics and the topic of improbability.

In today's world what people say about things is more important than what they really are. Truth is now about whatever is more popular. Like it or not.

Thought provoking, isn't it?
What can we do about it.

Unix

• Distributed systems
  http://josuah.net/blog/2019-01-10-distributed-system-overview.md

  A beautiful piece of ASCII art by josuah to help you visualize the components required to build a full fledge distributed system.

• Distributed permissions
  https://stebalien.com/blog/dracl-thesis/static/thesis.pdf

  Building a distributed system for sharing content that respects our privacy, that's a big endeavour. Also related to "Keeping time and date (11)" in issue 116 and the digital identity trend and discussions we've seen develop the past few years.

• No reboot
  https://unix.stackexchange.com/questions/226872/how-to-shrink-root-filesystem-without-booting-a-livecd/
  https://github.com/marcan/takeover.sh

  Ready to take it to the hardcore level, ready to risk it all, then this is the kind of thing that will grind your gears. Reboot is for sissies.

• BSDs and their love for signal innovation
  http://lkml.iu.edu/hypermail/linux/kernel/1411.0/03374.html
  http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=commit;h=27d2c738

  Why doesn't Linux implement the same behavior for SIGINFO as what the BSDs do. We are soon faced with the old cathedral vs bazaar and our dear friend the terminal line discipline.

• We had that conversation on irc
  https://dwheeler.com/essays/fixing-unix-linux-filenames.html
  https://linux.die.net/man/1/detox

  We had this talk before on irc and it was also in the newsletter too (Review "Let us never speak of it again" in issue 64). So here's an article (quite a long one) where the author proposes a solution.

• Removing a.out
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=eac616557050737a8d6ef6fe0322d0980ff0ffde

  With the availability of ELF everywhere a.out is finally being marked as expired in the Linux kernel.

• Random enough
  https://darakian.github.io/2019/02/17/on-java-securerandom.html
  https://hackaday.com/2015/06/29/true-random-number-generator-for-a-true-hacker/

  Remember "Lavarand" from 93, there is here yet another source of randomness you could possibly use. And another post about blocking issues caused by randomness.

• Yubikey ssh auth
  http://undeadly.org/cgi?action=article;sid=20190302235509

  This is a repetition of "2FA using a USB" in our very first issue, a guide the use a Yubikey as an HSM device to store ssh keys and use them for authentication.

• Writing a book on Unix
  https://joecmarshall.com/posts/book-writing-environment/

  Unix can be used as an IDE but also as a full fledged book editor. This isn't the best environment to do this, as it requires some technical knowledge to setup but it's interesting to put together.

• Font rendering
  https://pandasauce.org/post/linux-fonts/
  https://mobile.twitter.com/tapbot_paul/status/1004361530018852864
  http://www.antigrain.com/research/font_rasterization/

  We're back to the topic of fonts on Unix. So far we've covered so much, from font fallback and unicode, from specific engines tricks, to the actual stack and font rendering, to designing a font and custom typefaces, to creating fonts that will cover languages, to choosing the right typography, to making art with text, and more. This time we attack the subjective perspective, which fonts look good and what are the best techniques to apply. Be aware that opinions differ on the matter.

• Big words and new licenses
  https://writing.kemitchell.com/2019/03/09/Deprecation-Notice.html

  Another jump into the legal world this week, a popular topic of discussion. You might already have caught the train or maybe not. Take this as a reminder. Do you think this license is ambiguous? Do you think MIT and BSD deserve to be deprecated (See also "Signals for IPC? NO!" in 81).

• Extra because we've already followed this stuff before
  https://michael.stapelberg.ch/posts/2019-03-10-debian-winding-down/
  http://changelog.complete.org/archives/9971-a-partial-defense-of-debian

  Way back, recall when we had multiple issues about that "Nagging about Debian" in 64, that "More on Debian ranting" in 65, "APT and https" in 60, "APT getting it again" and "Debian systemd maintainer will not maintain systemd anymore" in 111. Well folks, there's more this week, the internet couldn't leave Debian alone.

• Emulate the right way on NetBSD
  http://polprog.net/blog/netbsd-hax/
  https://github.com/intel/haxm

  The quest to porting Intel hardare acceleration to NetBSD, the world of VM opens up.

• A follow up on this QNX Desktop
  https://membarrier.wordpress.com/2019/03/03/screenshot-galore/

  Everything seems to have fallen into place to build a desktop. There's even an hypervisor!

• Kernel headers
  https://www.phoronix.com/scan.php?page=news_item&px=Linux-In-Kernel-Headers-Proc
  https://lkml.org/lkml/2019/1/18/975
  https://www.tecmint.com/remove-old-kernel-in-debian-and-ubuntu/

  If you need to build kernel modules you need those, but then when you upgrade kernel you have to get the new headers with it. It can get messy to clean. The idea brought up about using /proc is attractive however it has its own issues.

• Pipelines
  https://nanxiao.me/en/what-you-need-may-be-pipeline-unix-commands-only/
  http://www.gibney.de/the_output_of_linux_pipes_can_be_indeter
  https://utcc.utoronto.ca/~cks/space/blog/unix/ShellPipelineIndeterminate

  When simplicity is key to solve big problems instead of relying on complex spidery solutions. But the same terseness may lead to confusion in rare cases. It's fun to run through the problem in the second link by trying out mixing builtin echo with non-builtin.

• OCaml for Unix
  https://ocaml.github.io/ocamlunix/index.html
  https://ocaml.github.io/ocamlunix/ocamlunix.pdf

  We see a lot of system programming in Go, Rust, even NodeJS these days (maybe we should share those too), but not a lot of OCaml.

• A quick history with dramatic music
  https://www.youtube.com/watch?v=JuHpABL46a8
  https://fosdem.org/2019/schedule/event/keynote_fifty_years_unix/

  Going over the history of Unix never gets old, add some drama music in the background, lots of events, wars, and you got a full movie.

• Worse is better, or give me back that Unix haters handbook
  http://yosefk.com/blog/what-worse-is-better-vs-the-right-thing-is-really-about.html

  Why things get replaced in the market, why "worse is better", why some argue in opposite directions, what does this have to do with Unix. The author draws in the opinion piece a discussion on world views and how it affects the way we handle building things.

• SRP
  http://srp.stanford.edu/whatisit.html
  https://bert-hubert.blogspot.com/2012/02/on-srp-some-implementation-notes-and.html
  https://crypto.stackexchange.com/questions/8245/why-is-srp-not-widely-used
  https://matthewarcus.wordpress.com/2014/05/10/srp-in-openssl/
  https://marc.info/?l=openbsd-announce&m=140711256104278

  SRP is a nice protocol for secure exchange and verification of passwords, however it hasn't been widely adopted. In the links of this entry you'll understand a bit why and see that it has even been pushed out of libressl for instance. Zero knowledge proofs tie well with the topic of differential privacy (see issue 45).

• Dropping Linux
  https://dirkriehle.com/2019/01/15/why-did-munich-drop-linux-and-libreoffice-for-microsoft-windows-and-office/
  https://www.theregister.co.uk/2018/07/27/lower_saxony_to_dump_linux/
  https://dirkriehle.com/2019/01/16/should-the-public-sector-consider-open-source-only-for-new-purchases/

  In the same vibe as the previous two sections, things get replaced for different reasons. All the arguments about worse and better are nil in face of public needs and things like habits.

• User perspective
  https://linuxmender.wordpress.com/2016/03/06/the-user-perspective/

  The conundrum of having something the most used not being maintained by the most competent possible contributors. "Taking is easy and talking is cheap".

• Extra on bots
  https://www.akamai.com/us/en/multimedia/documents/white-paper/akamai-scrapers-and-bot-series-managing-professional-bots-white-paper.pdf
  https://motherboard.vice.com/en_us/article/d33vpq/inside-the-wild-world-of-sneaker-buying-bots

  With all the talk about fake internet this white paper does a good job at portraying the different methods used by bot programmers to do what they do best.

“I am not a pessimist but I am a realist” - Always coming from the pessimist in the room

I'm reviewing old articles on my blog and I'm surprised by how some ideas are even more true today. We live in a society that is increasingly attached to realism, that cannot take metaphors, abstract topics, and ambiguity. Maybe this is an idea worth sharing for those struggling out there.

• Keeping time and date (11)
  https://venam.nixers.net/blog/psychology/2019/03/01/internet-time.html

  This is the concluding article of the time and date series. A reminder that time is subjective, that even though we can accurately calculate it we still feel it differently. Does this matter?

• Thiking in Csh, struggling like Csh
  http://blog.obligd.com/posts/the-joy-in-csh-and-vi.html

  These articles will probably be read as cliché or too oldish thinking from the people that are reading this newsletter however I've chose to share them for the single reason that this is the mindset that a lot of persons still have. I kind of like how the mechanism of each of these malware is explained.

  https://www.kernel.org/doc/Documentation/filesystems/dax.txt
  https://unix.stackexchange.com/questions/349769/linux-dax-direct-access-details

  A continuation of last week talk about non-volatile memory. This week we discuss DAX and XIP, what they're used for, the advantage, and the usual talk about data storage.

  https://man.openbsd.org/sysctl.8
  https://en.wikipedia.org/wiki/Sysctl

  Kernel tuning params has been discussed so much in this newsletter. It's surprising that it's still not part of POSIX though. Also it's interesting to see the different way that Linux and BSDs choose to implement it. See "Tuning the Linux kernel" in 112, and last week's "The sysctlview GTK tool to explore FreeBSD sysctl-mib-tree is now comited to FreeBSD Ports." of issue 114.

• Syncing time in VMs and containers
  https://pubs.vmware.com/vsphere-50/index.jsp?topic=%2Fcom.vmware.vmtools.install.doc%2FGUID-C0D8326A-B6E7-4E61-8470-6C173FDDF656.html

  This is closely related to the keeping time and date series. A note on how to sync, if it's necessary or not, the time on guest machines with the host.

  https://www.freertos.org/FAQWhat.html
  https://riot-os.org/
  https://circuitcellar.com/cc-blog/tinkering-with-time/

  RTOS on Unix, the overview of what it is about, examples, and with some of those generic thinking about time articles. There's lots of repetition, but it never killed anyone, on the contrary it makes it stick more. That last one is truncated but still interesting enough to read through. There's still one part to this series but it's not really about Unix, so this is it.

• Numbering
  https://www.datafix.com.au/BASHing/2019-02-17.html

  Another one of those cool formatting pipelines articles. I like them because they add spices to your thoughts and keep your mind working about different ways to attack a problem on the command line.

• Another week another puzzle
  https://www.itworld.com/article/2811646/operating-systems/unix-tip--debugging-tales--ssh-command-failure.html

  I can never get bored of such debugging stories. There's always something to learn out of them. And the more you learn the more you get used to it. I bet anyone reading this newsletter has encountered someone putting their hands in the air and saying "I give up", those stories teaches you not to and be more patient.

• Shebang
  https://lwn.net/SubscriberLink/779997/11de2bdc8dbc0d69/

  And old friend of ours "A thing which used to work stopped working, the unintended result of what should have been a harmless change. Ordinarily we’d call that a bug. Except this new behavior is actually what I wanted all along. So could the bug be a bug fix?", remember "OpenBSD doas update and virt" in 99 and "Kernel userspace boundary" in 108, we're at it again. While you're at it you can read those: "Do you need a blank line after the shebang?" in 36, "Magic bytes" in 100 and "Executables & default program" in 77.

• ETA
  https://github.com/aioobe/eta

  A tool that might not be useful to many but that you still need to know about. It's probably good for long running processes, or maybe those already have a monitoring mechanism in place. What do you think?

Thoughts

It's not that we have too little time to do all the things we need to do, it's that we feel the need to do too many things in the time we have. - Gary Keller

Sorry, no vermaden valuable news this week, he switched the publishing schedule to Mondays and so we'll get the issue next week. Or maybe we could start publishing the newsletter on Mondays too. Tell me what you think?

Unix

• So many init systems, so much history
  http://blog.darknedgy.net/technology/2015/09/05/0/
  https://engineeringblog.yelp.com/2016/01/dumb-init-an-init-for-docker.html

  The history of the trend and evolution of init systems along with an example of a choice of init for a certain scenario, here containers.

• NOVA fs
  https://lwn.net/Articles/729812/

  Remember "Speed up tests without code" in 96 where the author uses an fs in the ram to speed up tests, well this is sort of similar but on nonvolatile memory. The filesystems are usually optimized for disks, but that concept doesn't apply to memory, so we have to build one from scratch so that it's optimized making it snapshot-able at the same time. A nifty idea to say the least.

• Keeping time and date (9)
  https://www.linux.com/learn/distributed-systems-quick-and-simple-definition

  http://xtreemfs.org/

  In this issue we continue talking about time sensitive systems and operations, things such as the importance of time synchronization (there's a summary of many things we've seen in that wiki article), distributed systems, relatedness of events, and distributed storages. When multiple machines are involved time because an important factor.

• QNX

  https://membarrier.wordpress.com/2018/01/08/a-quick-update/

  https://en.wikipedia.org/wiki/QNX

  A forced reading and learning about a commercial Unix RTOS. This sort of leads into the coming links of next week for the Keeping time and date series.

• Building the networking stack
  http://www.saminiir.com/lets-code-tcp-ip-stack-1-ethernet-arp/
  https://www.kernel.org/doc/Documentation/networking/tuntap.txt

  https://linux.die.net/man/7/tcp
  https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt

  A series of articles about coding the TCP/IP stack from scratch on Linux. This is super interesting and makes you think about all the wraping and packing going around. I wasn't so accustomed with that stack before, it's good to know the inside out of it, at least a little. See also "Tun/Tap" in 64, and maybe all the encoding type of sections we've had too.

  https://lobste.rs/s/6iemve/fun_fact_gps_uses_10_bits_store_week_means
  https://en.wikipedia.org/wiki/Time_formatting_and_storage_bugs

  A topic that may sound simple to some but that still needs to be mentioned for the series of links about time and date, this is about files/inodes metadata, timestamps. We're not talking here about ultra precision time keeping though. Related to the discussion of mtime in "TIMEZONEs" of 101 and "The Big Bang" in 29. I added three links about GPS and time formatting bug as they sprouted in the news recently and we've been discussing that since the start of this series. Hope you're enjoying it, there are still two entries I'm going to add to close the series, the last one isn't really about Unix but tie things well together. Maybe in the end I'll put it all together in an article.

• After 2 years of security improvements
  https://archive.fosdem.org/2017/schedule/event/linux_desktop_versus_windows10/attachments/slides/1730/export/events/attachments/linux_desktop_versus_windows10/slides/1730/fosdem_linux_desktop_security.pdf

  https://wiki.archlinux.org/index.php/Security
  https://seclists.org/oss-sec/2019/q1/119

  Comparing a single corporate OS against a panoply of Linux distributions, that's not really fair. Maybe there are secure by default designs out there. In the meantime we've got a lot of work done in containerization, work on MAC, after meltdown and spectre, all the hype about fuzzing (especially Chrome team). How do you think we've done so far?

• Debugging ELFs
  https://osandamalith.com/2019/02/11/linux-reverse-engineering-ctfs-for-beginners/

  Tired of all the talk the past entries we've had about ELF, executables, LD, all sorts of formats, GOT and PLT. There's more in this one other than that talk, the thing I liked about this article is the thinking that goes into reverse engineering the executable, the whole process of dissecting it, this is the novelty here.

• XRender, wayland, composition, and Window management
  https://keithp.com/~keithp/renderproblems/render-title.html
  https://cmpwn.com/@sir/101568767470758639
  https://catfox.life/2018/07/31/exposing-the-wayland-lie/
  https://drewdevault.com/2019/02/10/Wayland-misconceptions-debunked.html

  I was about to share that presentation about XRender when those other posts and the flaming discussion about Wayland came up. I won't say much about the talking but let's just mention that there are some good points that were brought up, moreover the usual step needed for a new project hoping to replace something that has been there since forever, it'll take time and things will be missing and it'll take a lot of arguments to replace what is already working.

• Plan9 on static binaries
  https://9p.io/wiki/plan9/why_static/index.html

  A popular link this week. We've talked a lot about static builds in this newsletter, see "Static linked" in 111, "What to use other than statically linked executables" in 61. There are many opinions on the topic, what's your take?

  Multiple websites playing with the art of glitching, finding beauty in the non-perfect. See also both "Glitch art" in 84 and "DataErase" in 11.

• Fast file system again, some slides
  https://courses.cs.washington.edu/courses/cse451/13sp/lectures/16-ffs.pdf

  Something to go along with "BSD fast file system" from issue 109 and our never ending love of the data storage stack on Unix.

• Unix and Beyond
  http://lsub.org/iwp92007/IWP9-Ritchie.mov

  https://www.rapitasystems.com/blog/cooperative-and-preemptive-scheduling-algorithms

  This week let's focus on the concept of clock (similar to the tldp article in the third part of this series), reliant systems, what could go wrong if the time isn't right on a machine. This all leads to discussions about distributed systems, real-time OS, and other sensitive domains that require the time to be accurate.

• Anatomy of a shell
  https://drewdevault.com/2018/12/28/Anatomy-of-a-shell.html

  Are you thinking of implementing your own shell or get to know it better. This small post gives an overview of some thinking that goes into the parsing phase.

• Numeric username
  https://www.dampfkraft.com/how-to-make-a-numeric-username-in-linux.html

  Unexpected usernames made out of numbers only, want to do that and get weird unsolvable bugs, get ready. We do it because we can, is there any better reasons?

  https://blog.benjojo.co.uk/post/eve-online-bgp-internet

  What about launching 8000 VMs to run a simulated game-like network environment, check up what's needed to achieve this. The true BGP genius at his craft again.

• From the heap to the stack
  https://thesquareplanet.com/blog/smashing-the-stack-21st-century/

  Remember that series we did on the heap, well now let's tackle the stack a bit too.

• The internet of nags
  https://0x46.net/thoughts/2019/02/01/dotfile-madness/

  Dotfile management is hard, it requires knowledge of everything you've installed, default locations, environment variables, maybe a repository or directory, symbolic links, and much more.

  You might not have a use for the tools listed in this section whoever there's no loss in knowing they exist, you never know maybe this knowledge will be valuable someday.

• Checkpoint mode
  https://access.redhat.com/articles/2455211

  The fascinating topic of process state recovery. I forgot to mention it along with "Desktop Pausing" of 110, it's a better explanation of the "Cryogenic on Unix" in issue 24.

• Terminal madness again
  http://blog.robertelder.org/detect-keyup-event-linux-terminal/

  A discussion that involves two topics that I love, the TTY and X11. It's about how it's not really possible, and is probably a bad idea, to intercept key events in the TTY, especially key up events.

  https://unix.stackexchange.com/questions/278564/cron-vs-systemd-timers

  Tick-tock tick-tock, Chronos is ticking the clock making things happen whenever they need to happen. In this series we explore cron and scheduled execution of programs. From the explanation of the word, the standard, an early simple implementation, to examples and a new kind of system with a different thinking.

• Websockets the Unix way
  http://websocketd.com/

  In the same style as stunnel and inetd (see "Network and servers" in 58), we now have a simple websocket implementation taking input from normal streams.

• The design of Unix OS
  http://160592857366.free.fr/joe/ebooks/ShareData/Design%20of%20the%20Unix%20Operating%20System%20By%20Maurice%20Bach.pdf

  This is complementary to "The classic, the beautiful" of issue 105. Get your source from this issue and image from the next link. It goes in depth into the thinking needed to build an OS. As with this type of content, this is quite a big read so enjoy it over a long period or until you get bored, which hopefully will take some time.

• Installing research Unix
  http://decuser.blogspot.com/2015/11/installing-and-using-research-unix.html
  http://simh.trailing-edge.com/

  This is to go alongside with the previous link. The instructions are clear and simple to follow, enjoy! Kind of similar to "Doing it in V7" of 58.

• An upgrade
  https://github.com/hughpyle/ASR33

  Or how to connect the old to the new, quite an adventure in terminal land.

  To take the place of your user and give them what they need you first need to know who your users are. That first link lists everything that is required, and not so often thought about, to create a usable OS interface. A reminder of "Ever installed a Unix-like system for a friend who's not techie?" in issue 54. And finishing with yet another of those trendy OpenBSD on a laptop type of post.

  This week we switch the focus to NTP (see number 5 again), have a discussion about things we may not directly think about that affect time precision, and that finally leads us to talk about PTP for when NTP is not enough. Some interesting things to keep in mind: ppm, parts per million of beats can be used to measure clock accuracy, normalized frequency offset is also called drift. This will take us next week on the journey of real time clock, real time Unix systems, and maybe the use of time in distributed computing or other time sensitive operations.

• Static linked

  Building static binaries isn't that easy, this project aims at making it easier by providing recipe to do this.

• A post from that blog to follow
  https://begriffs.com/posts/2019-01-19-inside-c-standard-lib.html

  Remember the "New blog to follow" of 58, in this article we do a roundup of the C89 standard, a quick brief overview... Well brief but still quite thorough and entertaining.

• Getting inspired by OpenBSD
  http://austingroupbugs.net/view.php?id=1134
  http://austingroupbugs.net/view.php?id=859

  I find this case to be a convincing one, this is something that is required these days and that probably needs to be standardized across the Unix panoply.

• APT getting it again
  https://justi.cz/security/2019/01/22/apt-rce.html

  Remember "Nagging about Debian" in 63 and "APT and https" in 60, this is an update on the topic.

• Bonus
  https://markplusplus.wordpress.com/2006/10/01/pitch-correct-play-speed-with-mplayer/

  I've been listening to a lot of talks recently and speeding up the tempo changes the pitch, so if you don't want everyone to sound like a martian this will help. I've also learned that mpv has this behavior by default or through --audio-pitch-correction.

• Reminiscence of the olden' days
  https://apenwarr.ca/log/20190111
  https://apenwarr.ca/log/20190114
  https://medium.com/@bblfish/what-are-the-failings-of-pgp-web-of-trust-958e1f62e5b7

  I like it when someone applies their expertise of the past to a problem that they find similar in the present. Here we're discussing containers and showing a demo while saving a lot in the size of the image. As an extra there's a deep well thought meditation about the topic of multi-factor authentication, highly recommended.

• Desktop Pausing
  https://vermaden.wordpress.com/2018/09/19/freebsd-desktop-part-16-configuration-pause-any-application/

  https://github.com/retrohun/blog/tree/master/dt/xenixtales

  This jumped in the news recently, it's fun to have a blog hosted on github but inside of a readme instead of a github page.

• Explaining what is FreeBSD without shooting yourself in the foot
  https://www.fossmint.com/what-is-freebsd-why-should-you-choose-it-over-linux/

  Actually, scrap that title aside, it's not a perfect article at all. See also "And BSD for the Linux guys and gals" of issue 40 which was a bit better.

• FreeBSD malware
  https://www.youtube.com/watch?v=bT_k06Xg-BE

  Remember all that talk about PLT/GOT we had previously, well it's paying off, we're now able to understand what this talk is about. Also a continuation of "BSD hacking and security" in issue 63.

• Memory safety on Linux
  https://blog.araj.me/state-of-memory-safety-in-linux/
  https://www.kernel.org/doc/html/latest/security/self-protection.html
  https://kernsec.org/wiki/index.php/Kernel_Self_Protection_Project

  With all that talk about FreeBSD we're interested in a refreshment, let's see what's up in the Linux world. We could've checked OpenBSD but we're too used to jumping in that direction when it comes to security.

  https://cloud.google.com/blog/products/gcp/making-every-leap-second-count-with-our-new-public-ntp-servers

  Let's first review the first issue "Keeping time and date (1)" to refresh our memory about what is time and if days are really 24h. Are there instruments available to measure time precisely, how do they take into account the earth uneven speed. We want to still track time as a drift from that stable time but how do we propagate the changes, let's hear again about leap seconds and the new concept of smear time. And we finish with the introduction to the standard method to propagate external time, to sync up with the world and the sources of precise time, along with different examples on how to do that.

• TTY, change?
  https://lwn.net/Articles/343828/

  Traveling back to 2009 to remind us of the state of the TTY infrastructure on Linux, and mostly in general what needs to be supported and expected from all platforms.

Unix

• The philosophy still matters
  http://marmaro.de/docs/studium/unix-phil/unix-phil.pdf

  We often hear the "what is" or "how to", this paper is about the "why is".

• BSD fast file system
  https://www.youtube.com/watch?v=uF_J-itJDwM

  A really beautiful and approachable presentation about the BSD FFS, data storage on Unix is so much fun. A highly recommended talk.

• Bitrot data integrity
  https://dataswamp.org/~solene/2017-03-17-integrity.html

  We might have mentioned bitrot indirectly in this newsletter so let's do it explicitly now. This article should cover the basic concept.

• Remember university days?
  http://fabiensanglard.net/floating_point_visually_explained/

  Are you a university student and want to refresh your memory about how to encoding floats or maybe you've never seen those before, don't worry it's all explained in there. It's all about finding a way to represent and pack information in bits, just like what we saw in 71 "Let's play with encoding and formats" or 61 "ID3 tags" and many more issues before.

• Process infection
  https://www.tarlogic.com/en/blog/linux-process-infection-part-i/

  How to hide your mischevious deeds without them being noticed spontaneously, this is what is tackled in this article. It's only the tip though, the first one in the series touching listing processes that can be ptraceable.

• Keeping time and date (4)
  https://www.uninformativ.de/blog/postings/2018-09-15/0/POSTING-en.html
  https://lobste.rs/s/jeeq9d
  http://strugglers.net/~andy/blog/2018/12/24/the-internet-of-unprofitable-things/

  Let's take a small pause from the kernel stuff and start reviewing again DST, and slowly introducing the topic of NTP.

• Fun guy
  https://lukesmith.xyz/blogindex.html

  You might or might not like what this person is doing on their platform but it still deserves some attention.

• Console replacement
  https://arcan-fe.com/2018/10/31/walkthrough-writing-a-kmscon-console-like-window-manager-using-arcan/

  It's my first time cloning the Arcan project and trying it first hand by going through the tutorial, it's really nifty, give it a try. It gives that gaming framework vibe which is quite interesting and makes you wonder about what kind of user interfaces could possibly look like.

• What's that wmutils thingish on suckless rocks list
  https://venam.nixers.net/blog/unix/2019/01/07/win-automation.html

  I wrote an article to clarify things to those who get confused about X11 window manipulation utilities and for everyone else who simply are looking for new ideas. This was principally made to cover only wmutils but I thought of making it broader.

  Another case of wanting to optimize too early but an interesting discussion to have nevertheless. This reverbs back with the c10k and async problems ("Async IO" 105, "The C10K problem" in 52, "c10k follow up and a bit about flamegraphs" in 53).

  We started a bit last week with the types of hardware clocks the kernel can rely on, it's the point that we will focus on this time. Where is time stored on a machine, what actually ticks. As a bonus in this series and because it should be part of it, I'm adding again "What is time" from 85, this should include some ideas that will introduce future topics.

  I got a bit back into the WM world the past days, especially reading icccm and ewmh format specs. That first link is an interesting paper about issues that can happen when implementing a WM.

• IO Atomicity
  https://pluspora.com/posts/654da0f0d6120136b4f6005056264835

  In continuation with some topics from the previous research link such as race conditions, we review a tale from the old days about atomic writes. You can get "The classic, the beautiful" from 105 and tag along.

Thoughts

This is the first fressh issue of this new year. As cliché as it sounds let's emphasize some thoughts about change.

Remember those "Culture clash" from 86 and "Edge effect" from 84, let's start on this tone. Give yourself permission to make yourself a priority, at least for a while. Try out new things, or continue what you've left behind, or simply grow on the same path.

  Let's start this issue with a continuation of this series. Those should answer the following questions: What are the types of times: hardware and system (more on it later), how to get/set the current times, how to set the current timezone, what is this Unix/POSIX time we often hear about, what is one source of time (also more on it for next issues, leaving it ambiguous for now).

• A last one please

  http://www.cipht.net/2017/10/03/are-jump-tables-always-fastest.html

  This is quite an interesting case of "don't try to play it smarter than your compiler". An enjoyable read.

• Law enforcement guide to Linux
  https://cs.nyu.edu/~xiaojian/bookmark/linux/linuxintro.pdf

  Linux for forensic, this reminds me of "Command line for the data scientists" in 72, Linux can be for anyone. This is really just introductory (and a bit outdated), touching the basis but could still be considered a follow up on "We discussed a lot of forensic..." in 56, "File system forensic" in 43, "A forensic version of dd" in 42, and "Data security" in 73.

  I knew the Arch wiki was good but I'm still surprised by how thorough the security article is. As for all the rest of the content you can enjoy how security can be implemented in so many different ways, this covers a lot of ground. Maybe you can also read again about PAM, it's been a long time, "Everything you need to know about PAM" in issue 12.

• How programs are loaded
  https://lwn.net/Articles/630727/
  https://lwn.net/Articles/631631/

  Let's start with a question: How are programs loaded, what are they made of, and what's the link with the kernel.

• What is an ELF
  https://wiki.osdev.org/ELF
  http://www.cirosantilli.com/elf-hello-world/

  Alright, so now let's get a bit more accustomed with what ELF are about.

• Weaponization
  https://medium.com/@dmxinajeansuit/elf-binary-mangling-part-1-concepts-e00cb1352301
  https://medium.com/@dmxinajeansuit/elf-binary-mangling-pt-2-golfin-7e5c82bb482c

  http://www.linuxsecurity.com/resource_files/documentation/virus-writing-HOWTO/_html/index.html

  Those ones are easier to start with after diving into all the previous content, it wraps things cleanly together. As far as the last link is concerned, it's a bit of a hassle to read for me so far, not so well ordered and explained, but probably a must to bookmark it for later.

• Tools to manipulate ELFs https://github.com/BR903/ELFkickers

  There's nothing better than hands on experience to learn what we've been reading about. Other than using the usual tools such as readelf, objdump, and all the hex editors available, this repo offers much more.

• Linker
  http://s.eresi-project.org/inc/articles/elf-rtld.txt
  https://eli.thegreenplace.net/2011/11/03/position-independent-code-pic-in-shared-libraries

  What about libraries and linking in all that. A reminder of what we've seen in other issues about GOT and PLT.

• Some of the standard reference
  http://www.skyfree.org/linux/references/ELF_Format.pdf
  http://refspecs.linuxbase.org/elf/elf.pdf

  To wrap this up, this another week of long reads. In continuation with the dynamic linking articles series, we now tackle the body of concern: ELF. Also review "Magic bytes" in 100 and "Executables & default program" in issue 77. Maybe you should start with getting used to manipulating simpler byte structures, such as what we did before in issue 71 "Let's play with encoding and formats".

• NO ram, just registers
  https://emsea.github.io/2017/12/31/register-buffer/

  An interesting try at using available registers as a buffer. This might be useless but pretty cool nevertheless.

• Learn GRUB commands
  http://dcjtech.info/topic/grub-commands/
  https://askubuntu.com/questions/76309/play-a-sound-before-or-after-grub-loads
  https://www.techrepublic.com/article/how-to-password-protect-your-grub-menu/

  A quick and nice review of what the grub CLI offers. You probably can bookmark that when you're in a pinch and need to check them or maybe you just want to "play" a sound (that can't be muted), or add a password to your booting process, or boot from a network image.

• Awesome blog, xlib, ephemeral ports
  https://gavv.github.io/blog/ephemeral-port-reuse/
  https://gavv.github.io/blog/xlib-usage-examples/

  Two enjoyable articles, a tricky question of reuse and race-conditions over ephemeral ports, and the other a basic Xlib tutorial.

• HTTP2 and X509
  https://http2-explained.haxx.se/content/en/
  https://http3-explained.haxx.se/en/
  https://arxiv.org/pdf/1812.04959.pdf

  Two quick books by Daniel Stenberg, the author of cURL, on HTTP2 and HTTP3 and what has been attempted the last few years to speed up the web. The last link is your weekly dose of crypto, a study of common crypto libraries and how they handle X509 parsing. OpenSSL might be written by monkeys as vermaden mentioned but it's still doing fine. As far as I'm concerned I've dealt my good share with BouncyCastle, and it's not that bad as far as the programming side goes.

• The classic, the beautiful
  http://www.lemis.com/grog/Documentation/Lions/book.pdf
  http://warsus.github.io/lions-/
  https://people.eecs.berkeley.edu/~brewer/cs262/UNIX-annotated.pdf

  The original papers with additional commentaries to help you read through them. As time goes by we're more impressed by how it's a breeze to read through such fundamental building blocks to the current ecosystem. The second link is fun because you have the source attached on the window on the right, though it's missing the name of the files/sheets. This is quite a big reading so take your time, I'm not done myself.

• Exception handling in tricky code
  https://binarydebt.wordpress.com/2018/11/16/try-catch-in-linux-kernel/
  https://medium.com/@lduck11007/operating-systems-development-for-dummies-3d4d786e8ac

  An explanation of the macros used within the Linux kernel to catch faulty code with an extra article about building an OS from scratch.

• Network drivers in Rust
  https://www.net.in.tum.de/fileadmin/bibtex/publications/theses/2018-ixy-rust.pdf

  Everything can be rewritten in rust, that's the spirit we've learned from "How to for a Rust kernel" in 103. This fantastic and approachable paper (at least in the beginning) doesn't only cover how to translate a driver from C code to Rust but, as with the kernel one, gives a tutorial on how network drivers and on Rust in general work.

• Async IO

  http://aivarsk.github.io/2017/04/06/select/
  https://github.com/aivarsk/misc/tree/master/select

  A revisit of a basic topic under a new angle. Be sure to review the "The C10K problem" in 52 and "c10k follow up and a bit about flamegraphs" in 53

• Keeping time and date (1)
  https://en.wikipedia.org/wiki/Time_zone
  https://en.wikipedia.org/wiki/Greenwich_Mean_Time
  https://en.wikipedia.org/wiki/Coordinated_Universal_Time
  https://en.wikipedia.org/wiki/Universal_Time
  https://en.wikipedia.org/wiki/Daylight_saving_time
  https://wiki.archlinux.org/index.php/locale

  Keeping track of time is important for the activities humans do. Old mechanisms were based on the apparent sun position. However, appearances can be misleading, the earth speed is uneven and the sun is rarely at the highest point at noon. Not to mention that a day is not exactly 24h (we'll see the leap seconds in another issue)
  Improvement in worldwide communication and travel required parties/entities to agree in a mutually comprehensible time reference/standard.
  But time differs locally and so a synchronization mechanism needed to be adopted world wide, even if it differed from sun time. Many standards have been tried. The concept of time zones was put in place, an offset from the standard time, but had to be flexible depending on the people and especially countries and their economies. This is what UTC is about.
  Most timezones are whole number of hours but a few of them are offset by 30 or 45min. Then to make it more complex, daylight saving time (DST) appeared for weird economic reasons. Which these days are being reconsidered in the EU (see "TIMEZONEs" in issue 101).
  A nice start to the topic would be to know how we write time, the formatting. This is where the concept of locale on Unix comes in. The $LC_TIME where you specify one of the well known format you want to use for time.
  For the next issue more questions arises: What is time exactly, a unit, how is it measured in computers and electronic devices these days, especially on Unix? What about errors, drifts? How do we specify the base standard time and our offset from it on Unix. And much more to come.

• Bird eye over pulseaudio internals
  https://gavv.github.io/blog/pulseaudio-under-the-hood/

  Big projects, big planning and engineering, you need at least to have worked with one of those in your life as a programmer. Pulseaudio creates a lot of flamewars on the internet but it's still a nice humbling piece of engineering. This is quite a long read, so prepare yourself. It has everything, from the overview, to objects used within the code, to complex examples and applications.

• Docker Internals
  http://docker-saigon.github.io/post/Docker-Internals/

  Another dive into a deep topic, similar to "Talking about fan base" of 92, "Containers management" of 91, "Contain and protect" 76, "Contain and protect" of 104, "Containers from scratch" of 51.

• Font rendering
  http://dcjtech.info/topic/fonts-gui-and-x11/
  https://keithp.com/~keithp/render/Xft.tutorial
  https://www.x.org/releases/X11R7.7/doc/xorg-docs/fonts/fonts.html#More_about_core_fonts
  https://www.x.org/releases/X11R7.7/doc/xorg-docs/xlfd/xlfd.txt

  Another exploration into the world of fonts on Unix, see "More on typography" in 63, fonts on Unix, and "Xft but for xcb" in 91. The first article is a review of the stack we've already encountered, the second one goes over the Xft library design and usage, the last ones are a bit more explanation about the core fonts XLFD format so that you can compare it with the fancier Xft matching features (which is fontconfig matching actually). I highly recommend them to anyone interested in fonts and that want to follow up on what we've shared before.

• Building and interpreting
  https://url.spec.whatwg.org/#url-parsing
  http://www.craftinginterpreters.com/strings.html

  You might think it's straight forward to parse URLs but it's not, have a look. And the representation of the strings themselves is not as easy either. We also talked about this in the article "How to implement strings" of "Programming tricks and knowledge" of issue 100.
