Researchers performed genome sequencing scans on 130 people whose fathers were Chernobyl cleanup workers. Comparing the scans to control groups, they found evidence for the first time for "a transgenerational effect" from the father's prolonged exposure to low-dose ionizing radiation. ScienceAlert reports: Rather than picking out new DNA mutations in the next generation, they looked for what are known as clustered de novo mutations (cDNMs): two or more mutations in close proximity, found in the children but not the parents. These would be mutations resulting from breaks in the parental DNA caused by radiation exposure. "We found a significant increase in the cDNM count in offspring of irradiated parents, and a potential association between the dose estimations and the number of cDNMs in the respective offspring," write the researchers in their published paper... What's more, a higher radiation dose for the parent tended to mean a higher number of clusters in the child. This fits with the idea that radiation creates molecules known as reactive oxygen species, which are able to break DNA strands - breaks which can leave behind the clusters described in this study, if repaired imperfectly. The good news is that the risk to health should be relatively small: children of exposed parents weren't found to have any higher risk of disease. This is partly because a lot of the cDNMs likely fall in 'non-coding' DNA, rather than in genes that directly encode proteins.

Created in 1993, Slackware is considered the oldest Linux distro that's still actively maintained. And more than three decades later... there's a new release! (And there's also a Slackware Live Edition that can run from a DVD or USB stick...) . Slackware's latest version was released way back in 2016, notes the blog It's FOSS: The major highlight of Slackware 15 is the addition of the latest Linux Kernel 5.15 LTS. This is a big jump from Linux Kernel 5.10 LTS that we noticed in the beta release. Interestingly, the Slackware team tested hundreds of Linux Kernel versions before settling on Linux Kernel 5.15.19. The release note mentions... "We finally ended up on kernel version 5.15.19 after Greg Kroah-Hartman confirmed that it would get long-term support until at least October 2023 (and quite probably for longer than that)." In case you are curious, Linux Kernel 5.15 brings in updates like enhanced NTFS driver support and improvements for Intel/AMD processors and Apple's M1 chip. It also adds initial support for Intel 12th gen processors. Overall, with Linux Kernel 5.15 LTS, you should get a good hardware compatibility result for the oldest active Linux distro. Slackware's announcement says "The challenge this time around was to adopt as much of the good stuff out there as we could without changing the character of the operating system. Keep it familiar, but make it modern." And boy did we have our work cut out for us. We adopted privileged access management (PAM) finally, as projects we needed dropped support for pure shadow passwords. We switched from ConsoleKit2 to elogind, making it much easier to support software that targets that Other Init System and bringing us up-to-date with the XDG standards. We added support for PipeWire as an alternate to PulseAudio, and for Wayland sessions in addition to X11. Dropped Qt4 and moved entirely to Qt5. Brought in Rust and Python 3. Added many, many new libraries to the system to help support all the various additions. We've upgraded to two of the finest desktop environments available today: Xfce 4.16, a fast and lightweight but visually appealing and easy to use desktop environment, and the KDE Plasma 5 graphical workspaces environment, version 5.23.5 (the Plasma 25th Anniversary Edition). This also supports running under Wayland or X11. We still love Sendmail, but have moved it into the /extra directory and made Postfix the default mail handler. The old imapd and ipop3d have been retired and replaced by the much more featureful Dovecot IMAP and POP3 server. "As usual, the kernel is provided in two flavors, generic and huge," according to the release notes. "The huge kernel contains enough built-in drivers that in most cases an initrd is not needed to boot the system." If you'd like to support Slackware, there's an official Patreon account. And the release announcement ends with this personal note: Sadly, we lost a couple of good friends during this development cycle and this release is dedicated to them. Erik "alphageek" Jan Tromp passed away in 2020 after a long illness... My old friend Brett Person also passed away in 2020. Without Brett, it's possible that there wouldn't be any Slackware as we know it - he's the one who encouraged me to upload it to FTP back in 1993 and served as Slackware's original beta-tester. He was long considered a co-founder of this project. I knew Brett since the days of the Beggar's Banquet BBS in Fargo back in the 1980's... Gonna miss you too, pal. Thanks to long-time Slashdot reader rastos1 for sharing thre news.

"A new variation of the fake recruiter campaign from North Korean threat actors is targeting JavaScript and Python developers with cryptocurrency-related tasks," reports the Register. Researchers at software supply-chain security company ReversingLabs say that the threat actor creates fake companies in the blockchain and crypto-trading sectors and publishes job offerings on various platforms, like LinkedIn, Facebook, and Reddit. Developers applying for the job are required to show their skills by running, debugging, and improving a given project. However, the attacker's purpose is to make the applicant run the code... [The campaign involves 192 malicious packages published in the npm and PyPi registries. The packages download a remote access trojan that can exfiltrate files, drop additional payloads, or execute arbitrary commands sent from a command-and-control server.] In one case highlighted in the ReversingLabs report, a package named 'bigmathutils,' with 10,000 downloads, was benign until it reached version 1.1.0, which introduced malicious payloads. Shortly after, the threat actor removed the package, marking it as deprecated, likely to conceal the activity... The RAT checks whether the MetaMask cryptocurrency extension is installed on the victim's browser, a clear indication of its money-stealing goals... ReversingLabs has found multiple variants written in JavaScript, Python, and VBS, showing an intention to cover all possible targets. The campaign has been ongoing since at least May 2025...

There's the two behemoth architectures, x86 and ARM, and we probably all own one or more devices using each. Then there's the eternally up-and-coming RISC-V, which, so far, seems to be having a lot of trouble outgrowing its experimental, developmental stage. There's a fourth, though, which is but a footnote in the west, but might be more popular in its country of origin, China: LoongArch (I'm ignoring IBM's POWER, since there hasn't been any new consumer hardware in that space for a long, long time). Wesley Moore got his hands on a mini PC built around the Loongson 3A6000 processor, and investigated what it's like to run Linux on it. He opted for Chimera Linux, which supports LoongArch, and the installation process feels more like Linux on x86 than Linux on ARM, which often requires dedicated builds and isn't standardised. Sadly, Wayland had issues on the machine, but X.org worked just fine, and it seems virtually all Chimera Linux packages are supported for a pretty standard desktop Linux experience. Performance of this chip is rather mid, at best. The Loongson-3A6000 is not particularly fast or efficient. At idle it consumes about 27W and under load it goes up to 65W. So, overall it's not a particularly efficient machine, and while the performance is nothing special it does seem readily usable. Browsing JS heavy web applications like Mattermost and Mastodon runs fine. Subjectively it feels faster than all the Raspberry Pi systems I've used (up to a Pi 400). ↫ Wesley Moore I've been fascinated by LoongArch for years, and am waiting to pounce on the right offer for LoongArch's fastest processor, the 3C6000, which comes in dual-socket configurations for a maximum total of 128 cores and 256 threads. The 3C6000 should be considerably faster than the low-end 3A6000 in the mini PC covered by this article. I'm a sucker for weird architectures, and it doesn't get much weirder than LoongArch.

If you look at the table of contents for my book, Other Networks: A Radical Technology Sourcebook, you'll see that entries on networks before/outside the internet are arranged first by underlying infrastructure and then chronologically. You'll also notice that within the section on wired networks, there are two sub-sections: one for electrical wire and another for barbed wire. Even though the barbed wire section is quite short, it was one of the most fascinating to research and write about - mostly because the history of using barbed wire to communicate is surprisingly long and almost entirely undocumented, even though barbed wire fence phones in particular were an essential part of early- to mid-twentieth century rural life in many parts of the U.S. and Canada! ↫ Lori Emerson I had no idea this used to be a thing, but it obviously makes a ton of sense. If you can have a conversation by stringing a few tin cans together, you can obviously do something similar across metal barbed wire. There's something poetic about using one of mankind's most dividing inventions to communicate, and thus bring people closer together.

January was a busy month for Haiku, with their monthly report listing a metric ton of smaller fixes, changes, and improvements. Perusing the list, a few things stand out to me, most notably continued work on improving Haiku's touchpad support. The remainder of samuelrp84's patchset implementing new touchpad functionality was merged, including two-finger scrolling, edge motion, software button areas, and click finger support; and on the hardware side, driver support for Elantech "version 4" touchpads, with experimental code for versions 1, 2, and 3. (Version 2, at least, seems to be incomplete and had to be disabled for the time being.) ↫ Haiku's January 2026 activity report On a related note, the still-disabled I2C-HID saw a number of fixes in January, and the rtl8125 driver has been synced up with OpenBSD. I also like the changes to kernel_version, which now no longer returns some internal number like BeOS used to do, instead returning B_HAIKU_VERSION; the uname command was changed accordingly to use this new information. There's some small POSIX compliance fixes, a bunch of work was done on unit tests, and a ton more.

While starting this post I realized I have been maintaining personal infrastructure for over a decade! Most of the things I've self-hosted is been for personal uses. Email server, a blog, an IRC server, image hosting, RSS reader and so on. All of these things has all been a bit all over the place and never properly streamlined. Some has been in containers, some has just been flat files with a nginx service in front and some has been a random installed Debian package from somewhere I just forgot.

In the recent blog post on the work funded by Sovereign Tech Fund (STF), we provided an overview of the "File Hierarchy for the Verification of OS Artifacts" (VOA) and the voa project as its reference implementation. VOA is a generic framework for verifying any kind of distribution artifacts (i.e. files) using arbitrary signature verification technologies. The voa CLI ⌨️ The voa project offers the voa(1) command line interface (CLI) which makes use of the voa(5) configuration file format for technology backends. It is recommended to read the respective man pages to get …
