Ask HN: Who's an open source maintainer/project that needs sponsorship or help?
Nexus: https://github.com/jfilby/nexus
This is a web framework + ORM for Nim. It's in desperate need of more work to support DBs other than PostgreSQL and make the ORM more flexible. The web side also needs more work.
- Ask HN: Should I learn more languages?
-
Ask HN: Companies of one, what is your tech stack?
I use it mainly for high-performance backend engines. E.g. I'm writing an automated trading system and the trading engine is written in Nim.
I wrote a Nim web framework that has an ORM: https://github.com/jfilby/nexus. However I mainly use the ORM with the back-end engines. You could write a Django-style web app with Nexus + Nimja, but it's difficult to compete with the huge ecosystems of React and Flutter.

Ask HN: What is the job market like, for niche languages (Nim, crystal)?
It's not good for Nim, unfortunately. The language is great, but the community isn't that big.
If you're looking for a web framework with an ORM for Nim, check out Nexus: https://github.com/jfilby/nexus

Building a personal blog using Django
Django is a great MVC framework. It might be overkill for a blog as another poster wrote, but it's still a good way to learn Django.
If you ever want to learn Nim, please consider Nexus (https://github.com/jfilby/nexus) as I'm building it to be something like Django for Nim.

Show HN: Nexus Development Framework
Nexus is a Nim development framework.
https://github.com/jfilby/nexus
The aim to create a web framework similar to Django, with a built-in ORM. The view layer needs work, and is mostly built out of available libraries with Jester for routing and Nimja for templating.

Ask HN: What are some examples of elegant software?
Nim. It's just so quick and easy to write high performance code. That's why I'm writing a web framework for it, soon to be released: https://github.com/jfilby/nexus

OpenBSD System-Call Pinning
Well since https://www.openbsd.org/ still says
> Only two remote holes in the default install, in a heck of a long time!
I'm assuming not, but I could always be mistaken.

From Nand to Tetris: Building a Modern Computer from First Principles
> building a cat from scratch
> That would be an interesting project.
Here is the source code of the OpenBSD implementation of cat:
> https://github.com/openbsd/src/blob/master/bin/cat/cat.c
and here of the GNU coreutils implementation:
> https://github.com/coreutils/coreutils/blob/master/src/cat.c
Thus: I don't think building a cat from scratch or creating a tutorial about that topic is particularly hard (even though the HN audience would likely be interested in it). :-)

OpenBSD – pinning all system calls
> I don't know how they define `MAX`, but I'm guessing it's a typical "a>b?a:b"
Indeed: https://github.com/openbsd/src/blob/master/sys/sys/param.h#L...
> Then `SYS_kbind` seems to be a signed int.
It's an untyped #define: https://github.com/openbsd/src/blob/master/sys/sys/syscall.h...
I believe your whole analysis is correct, that running an elf file with an openbsd.syscalls entry with .sysno > INT_MAX will allow an out-of-bounds write.

tmux causing ANSI color-response garbage on attaching?
I can reproduce it. And this is the commit that causes the issue: https://github.com/openbsd/src/commit/d21788ce70be80e9c4ed0c52c149e01147c4a823

Sudo-rs' first security audit
This doesn’t really change your conclusion, but I think that’s the wrong file. This is the real doas afaict: https://github.com/openbsd/src/blob/master/usr.bin/doas/doas...
Still just a tidy 1072 lines in that folder though.
I spent 5 minutes staring at your file trying to understand how on earth it does the things in the man page, but of course it doesn’t.

OpenBSD: Removing syscall(2) from libc and kernel
OpenBSD developers are making serious effort to kill off indirect syscalls, the base system is completely clean, take a look at the work Andrew Fresh did to adapt Perl. He write a complete syscall "dispatcher" or emulator for the Perl syscall function so that it calls the libc stubs.
https://github.com/openbsd/src/commit/312e26c80be876012ae979...
The ports tree is also being cleansed of syscall(2) usage, until they're all gone.
msyscall, pinsyscall, recent mandatory IBT/BTI, xonly. OpenBSD is making waves, but people aren't really seeing them yet.
