The periodic between 1960s and 1990s was the Cambrian Explosion of #CPU architecture and #OS.

A single manufacturer, DEC, alone, had RSTS, TOPS-10, TOPS-20, RSX-11, VMS, Ultrix, OSF/1, and several other OSs I no longer recall. And DEC had a slew of different CPU architectures, and they each ran many other OSs made by various software companies. Also, there were loads of other hardware makers, large and small, each with a flock of different CPUs and a gaggle of different OSs.

In those days, we bitterly protested against this excess of “diversity”, on the grounds of software incompatibility, development impedance, and investment cost.

Finally, we now have that much-vaunted “uniformity” we always desired: Slackware Linux, Debian Linux, Fedora Linux, SUSE Linux, Gentoo Linux, Ubuntu Linux, Arch Linux, NixOS Linux, SELinux, …, @$&*#Linux, and they all run on the #x86.

Yep well, it's as I thought. Checking the source code I found that acpi_ibm only accepts a small subset of thinkpad events, and MICMUTE isn't one of them, contrary to Linux's thinkpad_acpi which accepts a far larger set (All?) including MICMUTE.

FYI, acpi_ibm accepts just these keyboard events:

LCD_BACKLIGHT
SUSPEND_TO_RAM
BLUETOOTH
SCREEN_EXPAND
SUSPEND_TO_DISK
BRIGHTNESS_UP

Just finished a PoC if i could bootstrap pkgsrc on my self-assembled minimal docker container.

Ingredients: skarnet-musl-toolchain. busybox-static, toybox-static, gawk, gsed, gtar, gmake, libz, libexpat, libxcrypt, libbsd, libmd, musl-{bsdcompat,fts,obstack,rpmatch}, and finally pkgsrc from netbsd.

after a few ins and outs, and learning the ropes, bootstrapping worked flawlessly.

Active AUR malicious packages incident

Is it a good thing or a bad thing that I haven neither pacman -Syu nor yay -Syu my Arch (btw) setup since... checks notes... 2021? (Yes, it's this out-of-date; actually, I did update specific packages such as librewolf using makepkg -si twice this year, but I didn't update anything else, let alone updating the repositories).

Thinking on the bright side, I wasn't affected by the xz thing, for example.

When... If... I get a new machine, and/or a new spinning HDD for my laptop, I'll likely ditch Linux altogether and go with illumos, OpenIndianna, or whatever niche OS esoteric and unknown enough not to be a target of AI-assisted exploits (even BSD-based OSes don't seem like an alternative, as I recall seeing something linking some SomethingsomethingBSD to newly-discovered exploits; luckily, illumos is overly obscure).

Or, to quote the meme, "I'm going to build my own, with..."

Anyone know why using sftp with Dolphin in Plasma is so slow in Alpine Linux?

Using Debian, doing the same thing is like greased lightning.

It's not network, ssh/scp/rsync/sftp command line works wicked fast between hosts with Alpine.

Something about Alpine and Plasma it seems. This has been an on-going thing.

Anyone know a workaround, beside using a different protocol I mean? This should "just work" like on other distros.

CLI tools can be faster for commonly-used commands .

My favorite dotfile manager to sync personal config files between machines is YADM... because there's so little to learn. It's basically `git` for dotfiles, where the files are edited in place. There's no extra symlinking or deploy step, just yadm commit/push/pull. Easy!

For edge cases of different settings on different machines, it supports templates and alternates.

An unsupervised agentic AI system working through compromised devs credentials (account) successfully altered bugs & pushed unverified code into multiple open source projects, including Fedora #Linux Anaconda installer.

Source: https://lwn.net/SubscriberLink/1077035/c7e7c14fbd60fae9/ Title: AI agent runs amok in Fedora and elsewhere [LWN subscriber-only content] Author and Date of publishing: Joe Brockmeier | June 10, 2026 Description: Agentic AI systems can be used to do a variety of things autonomously on behalf of a human user: open or manage bugs, generate code, submit pull-requests, and (apparently) even complain about rejection. In May, a Fedora developer discovered that an allegedly rogue agent had been pestering the project in a number of ways: reassigning bugs, fabricating unhelpful replies to bugs, and even persuading maintainers to merge questionable code into the Anaconda installer. It also submitted a number of pull requests (PRs), some accepted, to several upstream projects. The Fedora account associated with the agent has had its group privileges revoked and the messes have been mopped up, but the motive behind the agent's actions is still a mystery.

It's a bit scary talking to some people these days, who's first (and sometimes only) significant computing experience is a smartphone or closed-ecosystem PC, and not a general purpose PC.

Real Stockholm syndrome stuff: "I'm so impressed by Apple, my 2019 macbook still gets updates! most android phones only get 3-4 years"

Well a general purpose PC gets practically unlimited updates if you install the right thing on it.

By the way, our first two publications on evaluating #OpenBSD mitigations are out. Both of these papers evaluate some amd64 anti-ROP mitigations: specifically changing the register selection order and semantically equivalent rewriting of instructions that may produce a potential polymorphic gadget instruction. This tracks a paper by mortimer@ back in 2019 at AsiaBSDCon.

The TL;DR is "OpenBSD can shrink binaries a little and gain a little performance without any security loss simply by reverting these mitigations." The mitigations did not hold up to independent evaluation.

The first paper did an exact 1:1 port of these mitigations to FreeBSD and found that register reallocation eliminates only about 0.3% of unique gadgets, for a 0.5% increase in binary size (mortimer@ claimed 6% reduction and "entirely free"). It is useless at best but more likely actively detrimental, as it produces a false sense of security. It also found the instruction rewriting reduces unique gadgets by about 3.5% with a binary size increase of about 1.8% (mortimer@ claimed 5% reduction with 0.15% binary size increase).

We then did a separate implementation of the instruction rewriting mitigation to GCC in the second paper. Our GCC implementation does the older <xchg; op; xchg> dance, as that's what mortimer@'s paper described. This is way worse; producing about a 3% performance hit for no security benefit at all.

The only part of both mitigations worth saving is for basic arithmetic, OpenBSD LLVM now takes advantage of the fact that basic arithmetic has two forms. For example, the newer instruction rewriting mitigation turns
addq %rax, %rbx (48 01 c3)
into
{load} addq %rax, %rbx (48 03 d8)

The new instruction rewriting mitigation is genuinely free in terms of binary size and execution speed, but doesn't move the security needle, so this one can stay as it is harmless. Other rewritings still have the flaw of increasing binary size and reducing performance for no security benefit.

@nixCraft I started off in the world of Gentoo because I wanted to run a 64 bit OS on my operating system when that wasn't an option using windows. Since then, I've moved off of Gentoo and now I use a variety of Distros like Mint, Ubuntu, Bazzite, etc on my different PCs.

I think the majority of #Linux users probably don't feel that strongly about their distro, but there's a vocal minority out there that make it look like we all do.

Why is #Linux like a religion? Everyone thinks their distro is the one true path, and they’ll die on that hill usually mid `apt upgrade`

Last week I installed Linux onto a new laptop. Nothing special about that, but it got me thinking how with all the negative sides of technology we also have plenty of positive ones.

I downloaded a close to 5 gigabyte .iso from the distro's site, wrote it onto an USB drive with dd and booted off it. In less than 10 minutes later a working desktop installation was done.

The first computer I've ever installed Linux on was a 486. My modem was 2400bps so I did not download an .iso. Instead I went to bank, got US dollars, stuffed those and a order form I had clipped off a computer magazine into an envelope and mailed that. As fast as 3 weeks I was holding a CD box of Slackware, with two CDs and a booklet that was to become the source of frustration for months to come.

I recently installed Alpine onto an old Thinkpad I have at the arcade and that got me thinking if I still had it to build a system from scratch to that old Slackware level. I may have to find a period accurate PC and see how it all looked like back then. #linux
