Faster Euclidean algorithm

I recently found several ways to implement Euclidean algorithm. This code has 7 different gcd funcs implements Euclidean algorithm and measures the runtime speed of them. * gcd: gcd copied from math module in Nim's stdlib

choosenim 0.8.5 release announcement?

> The 0.8.5 version is basically the exact same as the 0.8.4 version A bit of an understatement, isn't it? I think the fix for #5 / #320 alone (use https URLs) is pretty significant.

choosenim 0.8.5 release announcement?

We have a couple other moderator updates that we wanted to bundle into one post. The 0.8.5 version is basically the exact same as the 0.8.4 version but now under the nim-lang GitHub organisation. It's only to be able to tell which version you're using. More updates will come soon!

Enabling compression on socket send/receive.

not sure what you mean there Araq. That is what I want to accomplish here, write 3 procs, sendUncompressed, sendGzip, sendDeflate, and when compression is enabled, just do client.sendProc = sendGzip or whatever. And all socket sends are handled by client.sendProc(data: string). I am stuck at thi

I guess my years working with C++ back in the day have tainted my brain. :P I have to think about what you've said. Many thanks.

Enabling compression on socket send/receive.

The `if` is only everywhere when you fail at using wrapper procs for send/recv consistently.

Request for feedback: `destructor` macro

` `=destroy`(x.field.addr[])` is a symptom, not the cause. The cause is you do something you shouldn't do. The compiler composes a perfectly fine destructor on its own. Here is when you need a custom destructor: When your type has a `ptr` or "handle like" integer type and you want to free the c

Enabling compression on socket send/receive.

I am trying to write a NNTP client for nim, for some reason this basic ancient protocol is not implemented in any lib I could find. NNTP protocol allows for gzip or deflate compression. I know an if boolean for every send is not a big deal, but if it can be done better, by swapping assigned proc

Fusion OS: a hobby kernel written in Nim

Kernel-tracked contexts/scopes (along the lines of transactions for DBs) is an interesting idea. If memory allocation { sbrk/mmap(anonymous)/etc. } is a part of that, it could actually _include_ a variant of arena-style memory management. Hierarchy may also be interesting (as with nested transa

Which IDE to use in 2024?

I might be one of the few on this forum who uses emacs, but I do recommend it. I'd say any investment to learn it will pay off over time IF you start using it for most of your text-based work (email, report writing, project planning, grading, IRC,...).

I can't speak for the initial decision since that was taken by someone else a long time ago. But I'm not opposed to switching it to an SVG and improving accessibility. Make a PR for it and if there was a good reason for it to be a PNG people can comment on it there. Otherwise we can merge it in

Fusion OS: a hobby kernel written in Nim

@grd (Araq obv. knows this), the OS does clean-up everything it can automatically, but to the OS, a "scope" is a "process". So, you do not need to free memory or close file handles or sockets or memory maps if your program logic knows a process is about to die & be reaped by the OS "soon enough"

Fusion OS: a hobby kernel written in Nim

Offtopic: As a guy who absolutely knows nothing about OS / kernel design, there is something that bothers me a lot: Why do I always need to close things? Why can't the kernel or the PL do that for me? I mean, at some point it just goes out of scope. Why do I need to manually close things? The t

Fusion OS: a hobby kernel written in Nim

The Nim PL can do that for you with the destructors feature. However, most of the standard library has yet to be ported to Nim v2 to do that. The OS cannot do it for you as the OS does not know the type layouts at runtime, for the OS the running process is mostly pages of random bits.
