gerbil VS hackernews

That's a strange one! Can you go to https://github.com/mighty-gerbils/gerbil/issues and post an issue outlining this with slightly more detail? What platform, C compiler, libc version etc.

New in std library: an S3 client, an SMTP client, SSL for Postgres (enables Heroku support), better CLI support (including multicall binaries), and plenty of module updates. Plus a few minor bug fixes.

See Gerbil Scheme homepage https://cons.io

Here is the discussion: https://github.com/mighty-gerbils/gerbil/discussions/1008

Gerbil Scheme < https://cons.io > just saw its release v0.18, with many usability and documentation upgrades, and a bunch of new functionality in the standard library. A "meta-dialect of Scheme with post-modern features", Gerbil layers a Racket-like module system (the best in the world by far) on top of Gambit Scheme (compiler that produces the fastest code), with lots of libraries as "batteries included" for production-level client/server code.

I'm more into Scheme than CL, but am aware of Coalton. My current lisp is Gerbil: https://cons.io which already has a type annotation system and will be enhancing it for the next major release (v19).

Another "post-modern" natively compiling Scheme is Gerbil Scheme [0]. It's seeing a lot of attention/enhancements lately, including some bounties to implement features.

this might help a little: https://github.com/wting/hackernews

I think it's a ratio of votes to time. I think as little as 4 votes can get something on the homepage if they come in fairly quickly.

The source code for hn is available if you want to go and look up the specifics. I'm not sure if this is the most up-to-date mirror, but the site doesn't change that often: https://github.com/wting/hackernews

Might not count as modern, but the original Reddit and HackerNews codebases:

- https://github.com/reddit-archive/reddit1.0

- https://github.com/wting/hackernews (actually news.arc, based on old hn)

There's also this https://github.com/wting/hackernews -- which is a version of the source code to the site from sometime in the past.

"Otherwise" was the operative word in my (slightly sarcastic) example. :)

Avoiding all caps words means you sometimes have to go back and change "FAA" back from "Faa".

HN's software is no longer open source, but at one time, this is how it processed titles on initial submission: https://github.com/wting/hackernews/blob/master/news.arc#L15...

And at any rate, #1 on HN is not the product of any simple rule like "most upvotes per unit time with some decay function applied." There is significant judgment in expressed in the way that stories are ranked. The sourcecode as of 2012 was enough to demonstrate this, but in my understanding yet more judgment has been applied since then.

"ad-hoc filesystem based solution" is the closest of your definitions, I think. Last time I saw/heard, HN was built in Arc, a Lisp dialect, and use(s/d) a variant of this (mirrored) code: https://github.com/wting/hackernews

Check out around this area of the code to see how simple it is. All just plain files. A database, of sorts, but not in the way you might be expecting: https://github.com/wting/hackernews/blob/master/news.arc#L16...

There is a modern maintained variant at https://github.com/arclanguage/anarki/tree/master/apps/news as well.

File syncing between machines is pretty much an easily solved problem. I don't know how they do it, but it could be something like https://syncthing.net/ or even some scripting with `rsync`. Heck, a cronned `tar | gzip | scp` might even be enough for an app whose data isn't exactly mission critical.

The old version in arc, mirrored at https://github.com/wting/hackernews/blob/5a3296417d23d1ecc90..., uses the file system as a database.

https://github.com/wting/hackernews/blob/5a3296417d23d1ecc90... shows the monotonically increasing number:
