  • John Goerzen: The Fundamental Problem in Python 3
    “In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.” – Douglas Adams This expands on my recent post The Incredible Disaster of Python 3. I seem to have annoyed the Internet… Back in the mists of (...)

  • Sylvain Beucler: Android Rebuilds updates
    What is it already? Android Rebuilds provides freely-licensed builds of Android development tools written by somebody else. New builds SDK 10 (API 29) and NDK 20 rebuilds are now available, as unattended build scripts as well as binaries you shan't trust. sdkmanager integration will be (...)

  • Joachim Breitner: Faster Winter 5: Eta-Expanding ReaderT
    (This is the fifth optimization presented in the “faster winter” series, please see that post for background information.) Another good approach to performance turning is look at the code after GHC optimized it. So I planted a -# OPTIONS_GHC -ddump-simpl -dsuppress-coercions (...)

  • Jonathan Dowland: 8-bit
    On Yesterday's Mary Anne Hobbs radio show she debuted a new track by Squarepusher, "Vortrack [Fracture Remix]", which you can now watch/listen to on YouTube: This track really grabbed my attention. Later that day you you could buy it in a variety of formats and quality levels on (...)

  • Ian Jackson: Debian init systems - what, another GR ?
    Sam Hartman, the Debian Project Leader, has proposed a General Resolution (a plebiscite of the whole project) about init systems. In this posting I am going to try to summarise the situation. This will necessarily be a personal view but I will try to be fair. Also, sorry that it's so long (...)

  • Joachim Breitner: Faster Winter 4: Export lists
    (This is the forth optimization presented in the “faster winter” series, please see that post for background information.) This is on a funny one: You can speed up your code by adding export lists to your modules! Why is that so? Without an export, the compiler has to assume that (...)

  • John Goerzen: A Mystery of Unix History
    I wrote recently about buying a Digital (DEC) vt420 and hooking it up to Linux. Among my observations on the vt420, which apparently were among the most popular to use with Unix systems, are these: DEC keyboards had no Esc key DEC keyboards had no key that could be used as Alt or Meta The two (...)

  • Mark Brown: Audio Miniconf 2019 Report
    This year's audio miniconference happened last month in Lyon, sponsored by Intel. Thanks to everyone who attended, this event is all about conversations between people, and to Alexandre Belloni for organizing the conference dinner. We started off with Curtis Malainey talking us through some (...)

  • Wouter Verhelst: extrepo followup
    My announcement the other day has resulted in a small amount of feedback already (through various channels), and a few extra repositories to be added. There was, however, enough feedback (and the manner of it unstructured enough) that I think it's time for a bit of a follow-up: If you have (...)

  • Mike Hommey: Five years of git-cinnabar
    On this very day five years ago, I committed the initial code of what later became git-cinnabar. It is kind of an artificial anniversary, because I didn't actually publish anything until 3 weeks later, and I also had some prototypes months earlier. The earlier prototypes of what I'll call (...)

  • Dirk Eddelbuettel: ttdo 0.0.4: Extension
    A first update release to the still very new (and still very small) ttdo package arrived on CRAN today. Introduced about two months ago in September, the ttdo package extends the most excellent (and very minimal / zero depends) unit testing package tinytest by Mark van der Loo with the very (...)

  • Joachim Breitner: Faster Winter 2: SPECIALIZE
    (This is the second optimization presented in the “faster winter” series, please see that post for background information.) The evaluator of the WebAssembly interpreter is highly polymorphic, as you can tell from the type signature of its main function: type CEvalT f m a = ReaderT (...)

  • Steve Kemp: Adventures optimizing a bytecode based scripting language
    I've recently spent some time working with a simple scripting language. Today I spent parts of the day trying to make it faster. As a broad overview we'll be considering this example script: if ( 1 + 2 * 3 == 7 ) return true; return false; This gets compiled into a simple set of (...)

  • Sylvain Beucler: SCP Foundation needs you!
    SCP is a mind-blowing, diverse, high-quality collection of writings and illustrations, all released under the CC-BY-SA free license. If you never read horror stories written with scientific style -- have a try [obviously this has nothing to do with OpenSSH Secure CoPy ;)] Faced with a legal (...)

  • Russell Coker: 4K Monitors
    A couple of years ago a relative who uses a Linux workstation I support bought a 4K (4096*2160 resolution) monitor. That meant that I had to get 4K working, which was 2 years of pain for me and probably not enough benefit for them to justify it. Recently I had the opportunity to buy some 4K (...)

  • Matthew Garrett: Extending proprietary PC embedded controller firmware
    I'm still playing with my X210, a device that just keeps coming up with new ways to teach me things. I'm now running Coreboot full time, so the majority of the runtime platform firmware is free software. Unfortunately, the firmware that's running on the embedded controller (a (...)

  • Joachim Breitner: Faster Winter 1: Vectors

  • Shirish Agarwal: Unbelievable
    This will be short as I have been having a touch of cold and flu over the last week. As I shared, I moved to mastodon from twitter and quite a number of people have moved on mastodon and many other instance which run mastodon. The best thing IMHO was that – a. I came to know the wide (...)

  • Wouter Verhelst: Announcing extrepo
    Debian ships with a lot of packages. This allows our users to easily install software without too much effort -- just run apt-get install foo, and foo gets installed. However, Debian does not ship with everything, and for that reason there sometimes are things that are not installable with (...)

  • Andrew Cater: Seems like I only ever write something at CD release time ... Buster release 2 is happening round about now
    Updating CD images again for Buster release 2. I've spent a happy day chasing down various CD images and discovering my ignorance once again :) Thanks to Sledge for having me around and also to Schweer - who wasn't feeling so well. No RattusRattus or Isy this time round - that meant I (...)

    OSS Journal, November 2026. In less than two month, with the end of the year 2026, Python 3 will be deprecated and will not obtain any further security updates.
