I'm once again caught thinking about how much nicer things could be if the #C preprocessor were just a little more... like a usual programming language.

And it seems like something that could have very easily happened, historically. It seems *so* possible that in like 1988 RMS said "It would be a huge win if I could `#defun (...)` and define a C macro in LISP instead of the existing macro language."

#TIL: #gdb "ptype /o" reports holes in structures (missed packing opportunities) #c

Just a few days ago, I lunched my new relay service for the #Fediverse and I'm really happy to see that there're already many ones connected to - more than 50 instances in just a few days!

But what makes me even really happy is to see, that my service [2] also gets linked in the release notes of #snac [1] / #snac2 - and I can recommend the usage of relay services (it doesn't matter which one!) to everyone. It provides more content from connected instances to you, but also brings your posts - from your local instance - up to other ones within the federated network where it can get much easier distributed around other instances.

#snac is the perfect way to host an own fediverse instance. Using the #ActivityPub protocol allows you to connect to all other instances. With the integrated #Mastodon API, you can also use most of your usual clients or web clients. Snac is light, fast, does not require any database and follows the KISS way - which the most of us BSD people are living. With relay services, it's the perfect match for singe-user instances and @grunfink is always open for ideas and to help! It does not always need to be #Mastodon, #GoToSocial etc!

And if you're using any other software, you may still benefit by using relay services. And if you're still looking for a guide, howto setup snac2 on #FreeBSD, my howto [3] might help you out.

I am writing some programming notes using #orgmode with C code snippets in it. When I export them in HTML, functions are not highlighted. They don’t have an associated class like variable types or language keywords. How can I improve this? #emacs #c

Neu in .NET 9.0 [5]: Halbautomatische Properties in C# 13.0

Bei einer Semi-Auto Property kann man Getter und Setter implementieren, muss dabei aber in C# 13.0 kein Field explizit deklarieren.

I guess you're doomed to be a polylang. Sorry to hear about the virus!
Discrete fourier transforms are defined by
(defun naieve-dft (l &key (sgn -1) &aux (len (length l)))
"consing naieve dft of list. Computes all twiddle factors. :sgn +1 for inverse."
(loop
:for k :below len
:collecting
(loop :for n :below len
:for w := (twiddle k n len :sgn sgn)
:sum
(* (nth n l) w))))
twiddles=(exp (* #C(0 1) sgn pi 2 k n (/ len)))
But this turns out to be overdefined

2024 in code. Lots of #C, #Pascal and #Fortran. My favourite project of 2024 was writing a Sharp MZ-80K emulator for the Raspberry Pico. Happy new coding year for 2025 to those who celebrate 🥳

If you're writing #Go and it doesn't feel like you're "writing C in Go", then you're not writing Go right.

If you're writing #C and it doesn't feel like you're "writing Go in C", then you're not writing C right.

Always bet on #C

Further along: "Compilers are starting to complain about the use of `sprintf()` and `strcpy()`, saying they are unsafe. So we define our own versions of those routines too." #C

Okay, let me do a better #introduction now that there's a bajillion more people here. I'm a former hacker, worked in #infosec, still into #programming and #electronics, currently more interested in #nature, both being in it and studying it.
