skybison VS riju

The parent comment is referring to the primary Python interpreter and runtime, CPython, not to libraries. There are of course other Python implementations, but [the only C++ one](https://github.com/tekknolagi/skybison appears to be unsupported.

Kind of! In my fork I run microbenchmarks on each PR. So you can see on, for example, https://github.com/tekknolagi/skybison/pull/456, that the change had a 3.6% improvement on the compilation benchmark. If you expand further, you can see a comparison with CPython 3.8. Unfortunately Skybison is still on 3.8.

This is also the pointer tagging scheme from the Ghuloum paper. I did not design it. Another tagging scheme I did not design is the Skybison scheme, which uses 0bXXX...XX0 to tag integers and 0bXXX...001 to tag heap pointers. This makes heap reads very easy (bias by -1 in addressing mode).

Skybison is a Python interpreter and I'm curious what the results look like. We also have some benchmarks in benchmarks/benchmarks.

If you take a look at the Skybison Python runtime, I would be happy to chat and help you poke around integrating it: https://github.com/tekknolagi/skybison

I am, in fits and starts, writing a bytecode optimizer for Skybison that takes advantage of type information.

Thanks for linking this. This is actually a superior offering to replit. They recently removed the ability to access a simple repl without logging in. Now you a) have to login and b) have to deal with this obtuse IDE-in-a-browser project creation shit. It's so many extra steps before I can run code.

I just want a URL in which I can run some code. https://riju.codes/ is literally that. Thanks!

An option is to do what I've done with my lang, Claro, getting the compiler and/or REPL hosted online on Riju. The maintainer is a very helpful guy that gave thorough docs you can follow for getting your language added. Check out https://riju.codes for the top level thing, and check out https://riju.codes/claro for an example what it looks like for a side project language to run there. Only issue there is you shouldn't expect regular redeploys as you continue working on the language. I just ask nicely every 3 or 4 months when I have some big change I'd like represented there and he redeploys.

There's the source code for such a site, if that would help: https://github.com/radian-software/riju

Docker + heavily restricted user + firewalls.. seems to get you much of the way there. I am aware that some work was done back in the pre-Docker day with Ruby's online sandbox to neuter Ruby's ability to make certain syscalls, but I imagine Docker, eBPF, or even using WebAssembly makes it a lot easier now.

Might as well link to an open source alternative: https://riju.codes/

Fun fact: Whenever I want to remember the name of this project, I just head over to https://HN.algolia.com and find out on the front page thanks to one of the most upvoted HN posts of all time, "Replit used legal threats to kill my open-source project": https://news.ycombinator.com/item?id=27424195

You should check out https://riju.codes it's really not that hard to get any old language running there :). It's a couple config files. I managed to get my language hosted there and the maintainer was really helpful in the process https://riju.codes/claro

Same here. However it did point me in the direction of the ex-interns awesome project which I used very often for technical interviews: https://riju.codes/

Faz fork do https://riju.codes (https://github.com/raxod502/riju) e implementa suporte pra matlab.

I miss the old repl.it, so I use https://riju.codes.
