Hello People.
This is my first fediverse post, featuring my first #assembly64 program in #linux. I am a #student who is just getting into #cybersecurity and love contributing to #infosec, #lowlevel stuffs and #linuxkernel.
I love to program in #c, and use #archlinux btw. Looking for people to connect. I installed LinkedIn a few days ago for connecting with people and figured out that it was a #scam in jobmarket, just data feed into companies. (No offense, just in my opinion).
I was suggested to start learning #assembly64 by a random reddit user when I asked some questions about #c programming and how to get better at it. Currently learning #syscalls in linux, and I guess assembly programming alongside with c programming is helpful - I can understand syscalls and registers (for some extent).
Looking forward for friends to connect. Follow me and I will follow you back - provided that we have same or similar interests. I am also interested in #russian arts, languages and techs - I am not a Russian btw.
I need suggestions \ #help on how to get started in fediverse, cybersecurity and low level stuffs. You can see my profile for more information.

My First Assembly Program
I'm a software developer and sysadmin who could really use being #fedihired.
What I'd really like to do is Rust, but once you ignore the dubious scammy stuff, there seems to be nothing out there. Prove me wrong with a counterexample!
I've spent decades fixing Enterprise mudballs mostly written in #Perl. If you've got a crufty legacy system that everybody else is too scared to touch, I'm your man. I love fixing stuff like that.
I've also done commercial #Scala, #Python, #C/#C++, and although I don't usually admit it on my CV but these are now Trying Times when everything is on the table, even #PHP (the longest six months of my life).
Perl naturally leads into Unix system administration and infrastructure. I've built and maintained mail clusters, VoIP systems, network monitoring, DNS management platforms, that sort of thing. If it's non-sexy but something which needs to be done, I'm there.
Available immediately, for contract or permie, onsite in Amsterdam/Randstad or remote to anywhere.
Drop me a private mention or mail peter@mooli.net if you have or know of something.
Reading the #perl 5.44 changelog I spotted "Simple (non-overflowing) addition (+), subtraction (-) and multiplication (*) of integers are slightly sped up, as long as sufficient underlying #C #compiler support is available", which is how I now know that `__builtin_add_overflow` and its friends and relations exist in basically every compiler that matters. 1/n
Finally got around to doing the C String lesson, passed the small exercise, and now I am moving on to C User Input. Going to bed late constantly is really cramping my ability to focus properly...I should probably fix that. 😂
The answer for the little exercise was:
#include <stdio.h>
int main() {
char message[] = "Hello";
printf("%s", message);
return 0;
}
The intended output was: Hello
A very basic ask, constructing a very simple program that would print whatever value was stored in "char message". You could literally put anything in there...I did for memory's sake, though I won't say what it was. ROFL
So, I am learning about C User Inputs...Here is the first real major lesson.
#include <stdio.h>
int main() {
int myNum;
char myChar;
printf("Type a number AND a character and press enter: \n");
scanf("%d %c", &myNum, &myChar);
printf("Your number is: %d\n", myNum);
printf("Your character is: %c\n", myChar);
return 0;
}
Very useful for user facing fields, handling inputs provided by the user in question. Naturally this could be done in many programming languages, I am sure.
Fun to learn this kind of stuff, especially when I finally make my own mini-programs!
Okay, fgets, stdin, sizeof combining are doing work in the whole gathering C User Inputs...As it allows you to print full names instead of just the first name. Here is an example of what I am talking about:
#include <stdio.h>
int main() {
// Create a string
char fullName[30];
//Ask the user to input some text (name)
printf("Enter your full name and press enter: \n");
//get and save the text
fgets(fullName, sizeof(fullName), stdin);
//Output the text
printf("Warm sands, %s", fullName);
return 0;
}
Here are the outputs:
Enter your full name and press enter:
Once name is entered:
Warm sands, Reese Rideout
I find myself learning a lot from these lessons. Eventually, I will put them to good use in making simple programs. It is good to learn the fundamentals, as I will know what to look up in case I get lost. ROFL
Now I am learning about C Pointers and Memory Addresses in tandem, how they can be leveraged! This is a very simple thing that creates prints the age value and prints a memory address based on the myAge value:
#include <stdio.h>
int main() {
int myAge = 43;
printf("%d\n", myAge);
printf("%p", &myAge);
return 0;
Expected Printed Values:
43
0x7ffe92b38204 (this output will vary based on the IDE used and your machine)
Two things you can see here... It's pretty hot! That's why I stayed home and implemented a missing feature into snac. That's what you can also see - it finally sends push notifications to devices! In this case, we can see notifications coming from #MastoBlaster App for iPhone.
What we can also see, it's still a bit faulty and not the expected content, but a first success here at least ;) I'll make some further adjustments when there's time and get in touch with @grunfink@comam.es to check if we can get this upstream. Thanks to @stefano@bsd.cafe for testing with me :)

Serena OS is what you get when modern operating system design and implementation meets vintage hardware like the Amiga computers. It is based on dispatch queues rather than threads, supports multiple users, is inspired by POSIX, yet retains its own character, is strongly object-oriented in terms of design and implementation and prepared for a cross platform future.
Written in C. Meant to be run on real Amiga hardware.
Meanwhile there is a petition via ourcommons to withdraw the bill(technical difficulties when I tried it just now,tho)

@mayazimmerman Looks like I should add a few #memes about K&R #C here
Alt...
Meme divided in two parts. Left part has a logos of some programming languages, like C++, Go and Rust, and has a text "Reject modernity".
Right part has a K&R C book's image and a text "Embrace tradition".
Alt...
The meme with cartoonish woman, reading the book for a child whi is sitting on her laps. The woman speaks: "And then they forgot allocate memory for the NULL terminator", and then the child happily answers: "SEEEGGGFAULT!"
Alt...
The meme depicts a queue of tired persons, wearing not so colourful clothes. This queue going through a big K&R C book and everyone transforms to a colorful anine girl.
@DaveMasonDotMe Pointers may look simpler with this #meme
Alt...
Meme with two white guys and the black background. First guy pointing to the text "int" and has an "int *" title. Second guy pointing to the first guy and has the "int**" title.
This is how the Linux kernel mailing list looks like from a browser.
From a mobile browser it looks less polished.
It's a *mailing list* you should read it from a email client, not a memory hungry browser, but if you are in the links browser it will look fine. Links is light ;)
The message is important; if you keep up with kernel development on the Linux side section audio drivers, you may find it interesting

A cursed feature of C in 1972: Labels and functions were reassignable (i.e., lvalues)!
For example, this is a clever way to initialize once:
goto init;
init:
ouptr = oubuf;
init = init1;
init1:
which is compiled to:
jmp *4120
mov 4136,4144
mov 4122,4120
Note the indirect jump and assignment to that address. All gotos used indirect jumps. This apparently would have also worked with functions.
Why does #Canonical wants to replace the fully developed #GNU #coreutils by their newly developed #uutils?
The only difference is, that the uutils are a reimplementation in #RUST of the coreutils, written in #C.
All they obviously do is to put issues into these absolute basic utilities that doesn’t exist in the originals.
To me that makes no sense. The only idea I get why Canonical might do this is to get more control over basic utilities of #Linux.

Ja, das ist so - wenn bei Bürgerlichen das #C wegfällt, bleiben oft nur Privilegien, Reaktanz und Konservatismus.
Ebenso kann ich Progressive nur davor warnen, dass Wahlverhalten von „proletarischen“, migrantischen oder jungen Menschen zu romantisieren.
Da kann ich selbstverständlich nur für mich sprechen: Verschiedene Flügel & Interessen haben gerade die Stärke der #Union als Volkspartei ausgemacht. Sie wurden von #Adenauer bis #Merkel auch immer dialogisch balanciert.
Was mich nun erschreckt und auch ärgert, ist die rechtslibertäre und fossilistische #Engführung der Bundes - #CDU , die auch in der Partei, in den Landesverbänden und der Kommunalpolitik für Entsetzen sorgt. So wurde aus der #CDA sogar schon die Entlassung von Ministerin #Reiche gefordert.
Ich kämpfe als Christ & Demokrat weiterhin für eine Volkspartei mit wahrnehmbaren #C und hoffe, dass auch Linke die Wucht von Demografie & medialer Rechtsmimesis reflektieren.
Meine Güte, jetzt postete Trump nach seinen Anwürfen gegen Papst Leo XIV. auch noch ein KI-Bild von sich selbst als heilender Jesus. ✝️
Und, ja, auch auf mich als Christ wirkt das gotteslästerlich, zumal der gleiche US-Präsident & Fossilist Millionen Menschen in den USA 🇺🇸 um ihre Krankenversicherung gebracht hat, Familien zerreißt, Hunger verursacht und mörderische Verbrechen gegen den Frieden begeht.
Das #C wird ja auch in #Europa & konkret #Deutschland öfter angeführt als ernstgenommen (leider auch in meiner Partei) - doch dieser Trump’sche Messias-Komplex geht inzwischen auch vielen MAGAs zu weit. Nach massiver Kritik auch aus dem eigenen Rest-Lager an seinem Größenwahn hat der feindselig-dualistische US-Thymokrat das schlimme Bild inzwischen wieder zu löschen versucht.
Und behauptet, es sollte ihn als „Arzt“ darstellen. 🙄🤭🤷♂️

When I say passable: in graduate school I wrote a Prolog interpreter in java (including parsing source code or REPL input), within which I could run the classic examples like append or (very simple) symbolic differentiation/integration. As an undergraduate I wrote a Mathematica program to solve the word recognition problem for context-free formal languages. But I'd need some study time to be able to write these languages again.
I don't know what the hell prompted me to reminisce about programming languages. I hope it doesn't come off as a humblebrag but rather like old guy spinning yarns. I think I've been through so many because I'm never quite happy with any one of them and because I've had a varied career that started when I was pretty young.
I guess I'm also half hoping to find people on here who have similar interests so I'm going to riddle this post with hashtags:
