About the #random thingie ... I need random data in #swad to generate unpredictable #session IDs.

I previously had an implementation trying the #Linux-originating #getrandom if available, with a fallback to a stupid internal #xorshift #PRNG, which could be disabled because it's obviously NOT cryptographically secure, and WAS disabled for the generation of session IDs.

Then I learned #arc4random is available on many systems nowadays (#FreeBSD, #NetBSD, even Linux with a recent-enough glibc), so I decided to add a compile check for it and replace the whole mess with nothing but an arc4random call IF it is available.

arc4random originates from #OpenBSD and provides the only sane way to get cryptographically secure random data. It automatically and transparently (re-)seeds from OS entropy sources, but uses an internal CSPRNG most of the time (nowadays typically #ChaCha20, so it's a misnomer, but hey ...). It never fails, it never blocks. It just works. Awesome.

Do any operating systems other than #Linux (#Windows, #macOS, #FreeBSD, #OpenBSD, etc) have an API for non-blocking file IO?

I know Linux has that in #io_uring, which can do almost any IO operation (even fsync) in the background and tell you when it's done, but is that the only OS with such a feature?

I have just taken the time to thoroughly read the following article

This article has led me to the conclusion that an Open{source} War will have to be waged against LLM large language model abusers of data collection.

The work of these bots is pure DDoS denial of service. An interesting set of offensive tools have been programmed and are already implemented. They have proven to be quite effective and are being refined into sophistication to literally work to knock these networks of bots offline, in a DOT MMORPG approach.

It is unthinkable that LLM bots steal our Open Source resources servers bandwidth and financial cashflow without serious repercussions!

WTF are LLM companies thinking? Even Meta has waged war against us!

LLM has waged a brutal war.

The Open Source Community is responding; even those at The Dark Side of the internet are making tools to assist everyone against Artificial Intelligence LLM DDoS attacks, which knock whole Open Source Networks offline, as we speak.

It doesn't matter if in the end it looks like a Terminator landscape globally on the IT scale. Open source will win. LLM will disappear...

The composition is a screencap of a news article displayed on an Android device. The article's headline reads, "Open source devs say AI crawlers dominate traffic, forcing blocks on entire countries." Below the headline, a subheading states, "AI bots hungry for data are taking down FOSS sites by accident, but humans are fighting back." The author's name, Benj Edwards, and the publication date, March 25, 2025, are displayed, along with the time, 6:36 PM, and the number of comments, 147. The article's first paragraph discusses a software developer named Xe laso, who reached a breaking point when aggressive AI crawler traffic from Amazon overwhelmed their Git repository service, causing instability and downtime. Despite configuring standard defensive measures, such as adjusting robots.txt and blocking known crawler user-agents, the issue persisted. The image accompanying the article shows a person sitting on a floral-patterned couch, working on a laptop. The person is partially submerged in water, with their legs visible above the waterline. The background includes a bookshelf with books and a potted plant, and the person is wearing a dark top and blue jeans with rolled-up cuffs.

@dec_hl I know.

Besides #RaspberryPiOS there's like @bunsenlabs / #BunsenLabs and me dabbling (@OS1337) tho technically they all are #i486 as they use #Linux kernels beyond the cutoff date for #i386 support.

• #NetBSD propably still supports i386 and potentially even i286...

Migration de VM sous #Proxmox, c'est tout de suite sur https://twitch.tv/ahp_nils ! #sysadmin #devops #twitchfr #twitchstreamer #TwitchStreamers #linux

The shortcut I was trying to take was to completely clone my old #Linux laptop, but in the process, switch from an `ext4` file system on the old new to `btrfs` on the new one, while still using LUKS and LVM, and still making sure all the right bits are done so I didn't overwrite files related to what I was changing, and still did all the steps to make sure the new system would boot.

It was much easier in the end to build from scratch, re-install packages and copy over my personal data.

I tried using an #LLM to take a shortcut to setup a new #Linux laptop.

The answers were technically correct, but failed to advise me it was a dumb idea that was more complex then it seemed, that was I was likely to screw something up (I did) and I should I stick with the standard `archinstall` tool.

Which worked great on my second try.

Sometimes intelligence is more than having the requested facts, it's knowing when to tell someone they are asking the wrong question.

#AI

I named my new #Linux laptop "fix", so now the login prompt says:

fix login: _

This will surely deter would be attackers.

Oops, almost forgot. My first #Linux was S.u.S.E. Linux April 1995. That was 30 years ago.

Before that, I had #NetBSD on my #Amiga 3000, but I only booted into it to play Hack.

First change since #swad 0.2 will actually be a (huge?) improvement to my #poser lib. So far, it was hardwired to use the good old #POSIX #select call. This is perfectly fine for handling around up to 100 (or at least less than 1000, YMMV) clients.

Some #select implementations offer defining the upper limit for checked file descriptors. Added support for that.

POSIX also specifies #poll, which has very similar #scalability issues, but slightly different. Added support for this as well.

And then, I went on to add support for the #Linux-specific #epoll and #BSD-specific #kqueue (#FreeBSD, #NetBSD, #OpenBSD, ...) which are both designed to *solve* any scalability issues 🥳

A little thing that slightly annoyed me about kqueue was that there's no support for temporarily changing the signal mask, so I had to do the silly dance shown in the screenshot. OTOH, it offers changing event filters and getting events in a single call, which I might try to even further optimize ... 😎

kqueue client code, manually relaxing the signal mask for just the single kevent() call waiting for new events.

In this Linux meme, a Linux user asks a genie to make them a smart Linux user. The genie replies, "I can't grant you that wish." So, the user asks the genie why not, to which the genie responds, "I couldn't make an Arch Linux user any smarter." The person in the meme is now blushing. ☺️

Just released: #swad v0.2

SWAD is the "Simple Web Authentication Daemon", meant to add #cookie #authentication with a simple #login form and configurable credential checker modules to a reverse #proxy supporting to delegate authentication to a backend service, like e.g. #nginx' "auth_request". It's a very small piece of software written in pure #C with as little external dependencies as possible. It requires some #POSIX (or "almost POSIX", like #Linux, #FreeBSD, ...) environment, OpenSSL (or LibreSSL) for TLS and zlib for response compression.

Currently, the only credential checker module available offers #PAM authentication, more modules will come in later releases.

swad 0.2 brings a few bugfixes and improvements, especially helping with security by rate-limiting the creation of new sessions as well as failed login attempts. Read details and grab it here:

"… would love to switch to another platform but whenever I try KDE or GNOME my experience is always ‘not quite as bad as Windows’, …"

For more than two decades, I was a huge fan of Apple's OS. Yosemite was the killer, I switched to PC-BSD.

Now, preparing to switch from FreeBSD to Linux:

– whilst I do miss the excellent aspects of Mac OS X, the worst aspects are so bad that I'll never switch back

– I can barely tolerate Microsoft's desktop environment, and that's not because I'm anti-Microsoft

– KDE Plasma ticks more boxes than any other DE.

YMMV :-)

🌇 Blog Post Forthcoming for GPUs 🌇

ok, it's morning nap time starting 5min ago... but I'm decently pleased that this morning I've wrangled the (yes, linux) kernel into behaving more decently (a little like FreeBSD's sanity) when allocating similarly ID'd PCIe devices to VMs for GPU passthrough.

Short version:
- many GPUs of same PCI ID type in host
- want certain VMs to get certain GPUs
- want main host to get one GPU for compute (server, no display)

FreeBSD:
- the above requires two loader.conf lines and one rc.conf line

Linux:
- oh lordy, how many modprobe and modules-load.d files, and grub entries, and kmod blacklists, rebuild initramfs, and rebuild grub menu, and don't forget to purge the entire nouveau driver from the kernel so it doens't try to backstab nvidia and steal your first born...
