  • Steve Kemp: Updated my linux-security-modules for the Linux kernel

  • Fran?ois Marier: Displaying client IP address using Apache Server-Side Includes
    If you use a Dynamic DNS setup to reach machines which are not behind a stable IP address, you will likely have a need to probe these machines' public IP addresses. One option is to use an insecure service like Oracle's http://checkip.dyndns.com/ which echoes back your client IP, but (...)

  • Erich Schubert: Contact Tracing Apps are Useless
    Some people believe that automatic contact tracing apps will help contain the Coronavirus epidemic. They won't. Sorry to bring the bad news, but IT and mobile phones and artificial intelligence will not solve every problem. In my opinion, those that promise to solve these things with (...)

  • Steve Kemp: Some brief sysbox highlights
    I started work on sysbox again recently, adding a couple of simple utilities. (The whole project is a small collection of utilities, distributed as a single binary to ease installation.)

  • Russ Allbery: DocKnot 3.04
    This is a relatively small feature release of my tool for managing software documentation and releases. I'm slowly moving all of my packages from Travis-CI to GitHub Workflows for automated CI. GitHub Workflows is much easier to configure and control, and I've been a bit worried about (...)

  • Russ Allbery: rra-c-util 8.2
  • Russ Allbery: C TAP Harness 4.7
    This is a small bug fix release to my testing framework for C packages.

You can get the latest release from the C TAP Harness (...)

  • Norbert Preining: Upgrading AMD Radeon 5700 to 5700 XT via BIOS
    Having recently switched from NVIDIA to AMD graphic cards, in particular a RX 5700, I found out that I can get myself a free upgrade to the RX 5700 XT variant without paying one Yen, by simply flashing a compatible 5700 XT BIOS onto the 5700 card. Not that this is something new, a detailed (...)

  • Iustin Pop: New internet provider ☺
    Note: all this is my personal experience, on my personal machines, and I don't claim it to be the absolute truth. Also, I don't directly call out names, although if you live in Switzerland it's pretty easy to guess who the old provider is from some hints. For a long time, I wanted to move away (...)

  • Norbert Preining: Switching from NVIDIA to AMD (including tensorflow)
    I have been using my Geforce 1060 extensively for deep learning, both with Python and R. But the always painful play with the closed source drivers and kernel updates, paired with the collapse of my computer's PSU and/or GPU, I decided to finally do the switch to AMD graphic card and open (...)

  • Evgeni Golov: Building a Shelly 2.5 USB to TTL adapter cable
    When you want to flash your Shelly 2.5 with anything but the original firmware for the first time, you'll need to attach it to your computer. Later flashes can happen over the air (at least with ESPHome or Tasmota), but the first one cannot. In theory, this is not a problem as the Shelly (...)

    It has been way too long since my last interview, but as the Debian Edu / Skolelinux community is still active, and new people keep showing up on the IRC channel #debian-edu and the debian-edu mailing list, I decided to give it another go. I was hoping someone else might pick up the idea and (...)

  • Jacob Adams: Roman Finger Counting
    I recently wrote a final paper on the history of written numerals. In the process, I discovered this fascinating tidbit that didn't really fit in my paper, but I wanted to put it somewhere.

    I was assigned 20 hours of work by Freexian's Debian LTS initiative, and carried over 8.5 hours from March. I worked 26 hours this month, so I will carry over 2.5 hours to May. I sent a (belated) request for testing an update of the linux package to 3.16.82. I then prepared and, after (...)

  • Russell Coker: IT Asset Management
    In my last full-time position I managed the asset tracking database for my employer. It was one of those things that “someone” needed to do, and it seemed that only way that “someone” wouldn't equate to “no-one” was for me to do it – which was ok. We (...)

  • Norbert Preining: Updating Dovecot for Debian
    A tweet of a friend pointed me at the removal of dovecot from Debian/testing, which surprised me a bit. Investigating the situation it seems that Dovecot in Debian is lagging a bit behind in releases, and hasn't seen responses to some RC bugs. This sounds critical to me as dovecot is a core (...)
