  • Mike Gabriel: My Work on Debian LTS/ELTS (November 2019)
    In November 2019, I have worked on the Debian LTS project for 15 hours (of 15 hours planned) and on the Debian ELTS project for 5 hours (of 5 hours planned) as a paid contributor. For LTS, I, in fact, pulled over 1.7 hours from October, so I realy only did 13.3 hours for LTS in November. (...)

  • Enrico Zini: ext4 and 32bit arm on 64bit amd64
    This is part of a series of post on the design and technical steps of creating Himblick, a digital signage box based on the Raspberry Pi 4. To provision Himblick systems we rely on using qemu-user-static to chroot into the ARM system. It turns out that there's an exoteric bug that (...)

  • Bits from Debian: Debian welcomes its new Outreachy interns
    Debian continues participating in Outreachy, and we'd like to welcome our new Outreachy interns for this round, lasting from December 2019 to March 2020. Anisa Kuci will work on Improving the DebConf fundraising processes, mentored by Karina Ture and Daniel Lange. Sakshi Sangwan will work (...)

  • Dima Kogan: python-gnuplotlib knows about multiplots
    I just released gnuplotlib 0.32. It can do this: import gnuplotlib as gp import numpy as np import numpysane as nps th = np.linspace(0, np.pi*2, 30) gp.plot( th, np.cos(th), np.sin(th)), _xrange = [0,2.*np.pi], _yrange = [-1,1]) import gnuplotlib as gp import numpy as np import (...)

  • Jonathan McDowell: Native IPv6: One Month Later
    I wrote a month ago about getting native IPv6 over fibre. Given that this week RIPE announced they'd run out of IPv4 allocations and today my old connection was turned off, it seems an appropriate point to look at my v4 vs v6 usage over a month (as a reminder, I used my new FTTP connection for (...)

  • Holger Levsen: 20191128-FOSDEM-MiniDebCamp
    Mini-DebCamp pre FOSDEM 2020 This is to inform you about a Mini-DebCamp happening right before FOSDEM 2020, in Brussels, which is a city in Belgium in Europe on planet earth. The Mini-DebCamp will take place at the Hackerspace Brussels (HSBXL) from Wednesday, the 29th of January 2020 until (...)

  • Vincent Sanders: Twice and thrice over, as they say, good is it to repeat and review what is good.
    Three years ago I wrote about using the AFL fuzzer to find bugs in several NetSurf libraries. I have repeated this exercise a couple of times since then and thought I would summarise what I found with my latest run. I started by downloading the latest version of AFL (2.52b) and compiling it. (...)

  • Daniel Silverstone: Rust 2020
    As in recent years, there was a call for posts about Rust in 2020. I've been sitting on my response for quite a few weeks because every time I try to write this, I think of other things I want to say, or a new "theme" I want to propose for Rust in 2020. First, some history about myself in (...)

  • Enrico Zini: Raspberry Pi 4 WiFi stops working at 2560x1440 screen resolution
    This is part of a series of post on the design and technical steps of creating Himblick, a digital signage box based on the Raspberry Pi 4. One full day of crazy debugging, and the result is that if the Raspberry Pi 4 outputs HDMI at a resolution of 2560x1440, the WiFi stops working. Any (...)

  • Joachim Breitner: Faster Winter: Statistics (the making-of)
    (This is an appendix to the “faster winter” series, please see that post for background information.) Did you like the graph and the stats that I produced? Just for completeness, I am including the various scripts I used. Nothing super exciting to see here, but maybe someone finds (...)

  • Joachim Breitner: Faster Winter 7: The Zipper
    (This is the seventh optimization presented in the “faster winter” series, please see that post for background information.) The last bit of performance could be considered a domain-specific optimization, as one might describe it as “introducing a control stack to the (...)

  • Joachim Breitner: Faster Winter 6: Simpler Code
    (This is the sixth optimization presented in the “faster winter” series, please see that post for background information.) The Wasm reference interpreter has a function step that performs one single one step of evaluation, by taking the state before (in a type called code), and (...)

  • Enrico Zini: Locating an SD card
    This is part of a series of post on the design and technical steps of creating Himblick, a digital signage box based on the Raspberry Pi 4. The first step in writing a script to setup an SD card image, is to locate the SD card device under /dev/, since we don't want to manually locate the (...)

  • Enrico Zini: Himblick: Raspberry Pi as a digital signage box
    Goal: set up a Raspberry Pi 4B as a digital signage box, together with Ulrike. We called the project Himblick, from Himbeere (raspberry) and Blick (view / gaze). From the point of view of the underlying debian/raspbian setup, the idea is to make it as solid and reproducible as possible, so (...)

  • 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 (...)
