#c

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.

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:

Rewrote the existing C code for a simple molecular dynamics simulation in Rust.
What a brilliant language. So clean and clear.
Fun experience. Took me 3 days. (No LLM help haha).

Codeberg.orgMolDyn_RustRust implementation of a serial, simple molecular dynamics code. This is being developed as part of porting an existing code from C to Rust to learn the Rust language. Later on, the project could be used to benchmark its performance against the C version to create a report on it.

Hey I'm still looking for work.
I've applied to a lot of places in my area and I'm getting nothing.

I'm a programmer at heart, but I've also been looking for regular entry-level jobs because there haven't been any coding positions open at my level as far as I could tell.

If you can offer me a job, it might save my butt. And if you can't offer me a job, could you at least share this post?

I live 30 minutes away from Bellevue if that helps.

I would claim that I'm *very* experienced with #programming in #C. But still, C gets annoyingly weird when it comes to #pointers *to* #arrays.

Does the following code look sober to you? (My compiler doesn't complain)

Especially interested in the highlighted line, but also the block above trying to expand the array ...

Context: I started work on a generic/configurable rate-limiter to add to #swad.
