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.

@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...

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.

@sborrill

Interesting, though, that #NetBSD is associated with bearded warriors and orange flags on... fire?

I thought #OpenBSD was more of the flame war operating system?

(I kid! I kid!)

A new #blog post appears!

I built a native GCC 14.2.0 for Mac OS X 10.4 Tiger PowerPC.

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 ... 😎

#C #coding

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

On my new NetBSD install I'm using 'oksh' - the portable version of OpenBSD's ksh - as my shell and wondered what in the world was going on with my arrow keys and moving through the shell history!

Adding...

set -o emacs

... to my ~/.kshrc sorted things out:

Framework Laptop 12 is now on pre-order:

That little machine looks gorgeous and the prices are surprisingly reasonable.

I have to resist ordering such a machine for #OpenBSD 7.7...

What about #NetBSD 10.1?

But is it supported by BSD...? Only one way to find out! 🤓

A new day, another install of a BSD... This time NetBSD on a Thinkpad T430s. 🙂

@ryoon I do but on my desktop, and I work on a laptop most of the time. I only have unaccelerated graphics, which is slow. But Chromium works well on #NetBSD current.

#NetBSD @netbsd a clean install of NetBSD 10.1 on AMD64 now seem to setup the terminal wrong? Is this a known issue? (I just pulled mc+bash using pkgin after clean install)

The screencap shows a screenshot of a mobile version of vermaden website. The background is black, and the text is in white, making it easy to read. At the top of the screen, there is a status bar displaying the time as 14:10, a Wi-Fi icon, a battery level of 90%, and signal strength indicators. Below the status bar, the text reads: "The Valuable News weekly series is dedicated to provide summary about news, articles and other interesting stuff mostly but not always related to the UNIX/BSD/Linux systems. Whenever I stumble upon something worth mentioning on the Internet I just put it here. Today the amount of information that we get using various information streams is at massive overload. Thus one needs to focus only on what is important without the need to grep(1) the Internet everyday. Hence the idea of providing such information 'bulk' as I already do that grep(1). The Usual Suspects section at the end is permanent and have links to other sites with interesting UNIX/BSD/Linux news. Past releases are available at the dedicated NEWS page." The text is formatted in a simple, straightforward manner, with each paragraph clearly separated. The word "NEWS" is highlighted in blue, indicating a clickable link. The overall layout is clean and easy to read, with a focus on providing information about a weekly series related to UNIX/BSD/Linux systems. Ovis2-8B 🌱 Energy used: 0.325 Wh
