> CrossDB. High Performance Embedded Database Development Framework. https://crossdb.org/
RDBMS style database (tables, rows, indexes), but no SQL; everything is done directly with a library and C Macros. You define tables using C Structs.
I suspect this is blazing fast. The use case would be replacing SQLite any time SQL just isn't fast enough. But it would also mean writing your own join code, so there's the tradeoff.
Edit: May not be Open Source.
It turns out that it's possible to have associated types and values in #c using a few extensions supported by #gcc and #clang . The basic foundation for this is zero-length arrays: you can insert a unit-alignment zero-length array field into any `struct` or `union`, and although it won't affect the layout or storage of the type, the array element type (which can be a `struct`) can be extracted with `typeof()`.
Wrote an implementation of the "three shears" non-destructive sprite rotation which may be of some use to retro platform developers.

The decision to use Ruby for Mastodon was a poor choice, to put it mildly.
The diagram below shows relative energy consumption, with values normalized to the most efficient one. So C, as the most energy efficient, has the value 1.

I have no idea why it took me this long to notice. This application uses:
printf("\nblah blah");
Instead of:
printf("blah blah\n");
Part of the problem is when it prints a warning or an error and then waits for the user to press a key to continue. Without the trailing \n, the error message never gets flushed!
I cannot fix this without touching every single printf() in this old-style C application.
This may encourage me to switch everything to C++ sooner.

New Blog Post: Some links from May 2023
https://pbarker.dev/posts/2023-05-31/some-links-may-2023/
I'm still in the process of trying out different styles of blogging to see what works for me. Today we'll be roleplaying as a link blog, but with one aggregate post covering the month of May instead of one post per link. Let me know what you think!
Topics covered: #C #LinuxKernel #Rust #Python and a grab-bag of others.
#SectorC: A #C #Compiler in 512 bytes
“Big Insight #2 is that atoi() behaves as a (bad) hash function on ordinary text. It consumes characters and updates a 16-bit integer. Hashes are perhaps the holy-grail of computer-science. With a good hash, we can just side-step all the hard problems by trading them for an even harder problem (hash collisions), and then we just ignore that harder problem. Brilliant. (sticks fingers in ears) 🤪”
@preslavrachev @danielquinn Depends on the experience, I think. I learned #C back in the mid- to late-80s and many languages since. #golang feels more like C in terms of error handling with a slight bit of C++ like thiscall calling convention for associative funcs. And as much as I like #rustlang for systems programming or WASM, it's like writing STL but with better errors when you inevitably anger the compiler. Go is a no-frills, simple language not getting in my way - great for many tasks.
You mentioned you are interested in: rust, javascript, and c.
...
There are hash-tags for each of those —
You can follow each of those hash-tags.

Also, if you look at who posts under each of those hash-tags (and look at their profiles), you may find other people to follow.

@EndlessMason #FFI works with either static or dynamic linking. #Perl and many other language toolchains default to the latter, but you can still built a big statically linked binary if you’re so inclined.
In contrast, #GoLang (for example) defaults to static linking that includes the runtime along with your code in one executable. It does have a `cgo` feature that lets you call #C code by building and compiling C glue code with your C compiler and then linking it with your #Go.

@EndlessMason Almost every “safe” language has some kind of foreign function interface where guarantees break down. #Java has JNI, Microsoft .NET has P/Invoke, and #Rust just calls theirs #FFI.
Perl’s XS is a glue language mostly made up of #C macros that lets you wire up Perl’s guts to C code. There are also alternatives like #SWIG and FFI::Platypus, the latter of which uses a separate portable library (written in C, natch) that can talk to lots of calling conventions, not just C.

「 Now, before you go out and write your next project in Lisp, you should keep something in mind. Lisp is not the fastest or smallest language out there, it was not designed to be so.

「 Not differentiating between C and C++ also has the side effect of ostracizing new users. Many beginner programmers are lead by the term “C/C++” to think that they’re basically the same language. In fact there are many tutorials out there that are advertised as “C/C++ tutorials”, continuing the confusion. This can also scare away C beginners by making them think that understanding the complexities of C++ are required to understand C 」

#Swift is a nice language. Having interop between Swift and #C++ would be neat, but with Socket Runtime we would lose out on a lot of code reuse, Windows and Linux are mostly C/C++ code bases, and our Android is mostly C++ via the #JNI, as a result there’s actually very very little #ObjC++ in the project. I’m pretty much +0 on the idea of interop.

#introduction
Hi, I am known as dunkelstern almost everywhere, in real life just call me “jo”.
I am a backend-developer using python and #javascript by day, but i am living on github by night too and working on one of those unfinished projects there (#rust, #c, #python and #cad)
If I am not tinkering with my #smarthome you will find me in the guts of some #3dprinter or fiddling with some #electronics . Currently you'll find me in the guts of a Deckel FP4 #CNC mill.
On the weekend you’re likely to find me in our #makerspace habitat augsburg
Say hello some time :)
#introduction
Hi, ich bin fast überall dunkelstern, im echten leben sagen die leute meistens Jo.
Ich arbeite als backend-entwickler mit python und #javascript, bin aber auch privat auf github zuhause und kippe dort meine drölf millionen unfertige projekte ab (#rust, #c, #python und #cad)
Wenn ich nicht an meinem #smarthome bastel dann wahrscheinlich an irgend nem #3d-drucker oder sonstigem #elektronik gebastel. Seit neuestem könnt ihr mich auch in den Eingeweiden einer Deckel FP4 #CNC Fräse finden.
Am wochenende findet ihr mich im habitat in augsburg, meinem #makerspace
Sagt mal hallo :)
And my next #C question 🙂
I use #popt a lot, it is great.
I always find some memory issue left over when running #valgrind, caused by popt. It is always small and so not something I worried much about.
I noticed it seems to be that a string argument to my command from popt is in fact malloc'd. I.e. I can free() it without error, and that fixes the valgrind complaint.
But the man page on popt does not say which things it malloc's.
Does popt always do it?
On holiday with the rents and my laptop packed up, so my current solution for coding is borrowing my sister's screen tablet (since it fits nicely in a backpack) and using a Pi 3 as my main coding device.
Honestly, not great, #RaspberryPi 3 is just a little too slow to run a browser well so even just looking up basic things is easier on my phone.
But the actual coding part is fine. Doing stuff for #C at the moment because I restarted the #CS50 . Wish me luck.
Let's settle this once and for all.

This engineer is my adult son, Nick Morearty. He started as a Computer Engineering major at UC Santa Cruz but ended up deciding to take a different path. He has taken NuCamp’s Full-Stack Web + Mobile Development bootcamp, and I’ve been teaching him all about software engineering for the last ten years--since he wan ten years old. In 2020 he got a perfect 5 on the AP Computer Science test, self-taught from a book and tutored by me.

With everyone investing in #ai, I am going to give my opinion on the subject and my predictions on the future.
Disclaimer: I am a CS student, not an industry professional yet.
I think it is very likely that #aiDrivenDevelopment will become a thing.
However, the thing that is currently holding it back, is the ai will sometimes "hallucinate" and do things wrong. In addition, ai code tends to be less secure, not unlike just copying code from #stackOverflow without checking it.
However, I imagine those problems will be lessened overtime, as it wasn't all that long ago that ai generated hilarious and garbled stuff from prompts.
I think prompt engineering might end up becoming a core part of cs courses.
I think the most similar example I can think of this development is the development of high level #programming languages, such as #python.
Everyone knows python and #java are much slower than #c, #c++, or #rust. However, it is often quicker (and thus cheaper) to write in python when speed does not matter.

Hi, just moved to this instance so is time for a new #introduction!
I love open source and also do (retro) gamedev (ZX Spectrum, Amstrad CPC, MSX and Commodore 64; sometimes PC), and other types of "dev" in #Scala, #Python, #C, #Z80, and #Haskell.
My games are always free to download and play, go and check:
(some of the retro ones have physical edition too)
Moved from mastodon.sdf.org.
Hey #compilers folks, I'm looking for a sample code in #C that depicts a for-loop compiler optimization based on the fact that a signed overflow is UB.
for(int i=0;i<=N;i++) cannot overflow (UB) but can with unsigned, which is why int is preferred. What benefit does the monotonic property assumption give to the compiler? Any example to demonstrate the optimization?
Now, using <= is actually rare in my experience, so can a similar optim be triggered with let's say for(int i=start;i<end;i++)?
I added #ATS to the #RosettaCode task for the #Mandelbrot set:
Mandelbrot set - Rosetta Code https://rosettacode.org/wiki/Mandelbrot_set#ATS
The #C entries include some #OpenGL stuff, though, which I am tempted to duplicate in ATS.
A Puzzle for #C language lawyers:
Can you think of a way to modify the part of this program between // MODIFY THIS PART and // END so that the whole thing fails to compile, but, and this is key, it compiles again if you replace extern int getgroups(); with extern int getgroups(int, gid_t *); ?
#include <sys/types.h>
extern int getgroups();
// MODIFY THIS PART
typedef int (*posix_getgroups_ptr)(int, gid_t *);
volatile posix_getgroups_ptr getgroups_p = getgroups;
// END
int main(void)
{
return getgroups_p != 0;
}
This #compiler for the #RosettaCode Virtual Machine assembly language can now target any of #ATS, #C, #Mercury, or #Scheme --
https://sourceforge.net/p/chemoelectric/rosettacode-contributions/ci/default/tree/vmc.dats
The Scheme code runs very fast in #ChezScheme, so-so in all else I have tried. I wonder how they do it. Maybe a lot of C code (instead of Scheme) in the runtime is part of it?
The generated Mercury is not so fast, but such is life with Mercury. It’s fastish, considering.
I decided to keep going and have added "vmc", the virtual machine compiler: https://sourceforge.net/p/chemoelectric/rosettacode-contributions/ci/default/tree/vmc.dats
No guarantee it works at any given time--though, if I am good, I can work with Mercurial branches. Right now it can compile to #ATS and to #C
#Compiler #FunctionalProgramming #ATSlang
The ATS it makes does tail calls. The C uses goto--many more goto than are needed, but optimizers might clean that out. The generated code is in continuation-passing style.
@Edent it may not be closed any more but #SunMicrosystem's #C #Compiler was a closed-source thing #cc (now #Oracle Developer Studio so chances of being #opensource are slim! https://en.wikipedia.org/wiki/Oracle_Developer_Studio)
Haha this is great. Ken Thompson refuses to take a test on how well he knows C, so Google won’t let him commit code. #C #Software #Developers #UNIX

(This is true because OCaml is an UNSTANDARDIZED language in which they change things.
I used to work on the code of ANT, which was written in OCaml, but I think it would require substantial rework to function with the current compiler.
Standard ML OTOH is a language with a thorough standard, like #Fortran or #Ada. You can write in it today, have your program work practically forever. It’s a deliberate plan. #C nowadays is like that, too.)
March 21: "Foundations First: Improving C’s Viability in Introductory Programming Courses with the Debugging C Compiler" - a live talk, evidently viewable over Zoom
If you ever teach people C or learn C, this might interest you
PSA: Did you know that function argument evaluation order in C is undefined, and gcc / clang are actually doing the opposite of each other?
I did, but that knowledge didn't make today's debugging session much shorter and less puzzling.
The starting point was that the same code worked fine on Linux but doesn't work on macOS. Nothing system-specific anywhere near the error.
As it turns out, somewhere deep down there was some code relying on a specific argument evaluation order. Something in the shape of
copy(reader_read_data(r, reader_get_remaining(r)), reader_get_remaining(r));
With gcc this copied the remaining amount of data, with clang this silently copied nothing. gcc is evaluating arguments right-to-left, clang left-to-right. So clang was first advancing the cursor to the end, and then the remaining amount of data was actually 0.
Should you write such code? No. Does it make sense for the code to behave differently with different, well-behaving compilers? Also no.
The code in question did not cause any compiler warnings, and no static code analyser I tried (including coverity) detected it either.
Fortunately another thing Rust got right: argument evaluation is explicitly defined as left-to-right.
And this is just one of the parts of C with undefined, unspecified or implementation-defined behaviour. Far too many footguns to keep in mind to realistically avoid having one or another showing up somewhere sooner or later.
