Is this supposed to be a joke? It's clearly an empty repo. Either this is a mistake, or this is a really, really misguided attempt at a joke from Twitter.

It was created 20 minutes ago. Maybe a WIP?

For a company of Twitter's scale and resources, any public repos are supposed to go through legal to clear (this is how things work at every FAANG I've worked at).

So if it was a WIP, it'd be a private repo until it's ready to release publicly.

I've worked on very large scale recommendation systems at a FAANG. If Twitter's system resembles anything like ours, the concept of publishing or open sourcing "the algorithm" doesn't make sense. Even if we were to open source all associated code and publish all related documents it would be very difficult to make sense of the entire system. That is precisely why companies such as Twitter A/B test the hell out of eve…

It would be gamed 100%.

I know the algorithm i use, it ends with ORDER BY date DESC.

Is that actually possible on Twitter? (I have an account but don't use it.) I do believe them that when a user follows several 100+ other users, it would probably be impossible to read every tweet chronologically.

Yes. It is. It's been an option since... forever? Many many years at least. https://i.imgur.com/JM6saa2.png

For about a week they made a change that prevent that chronological timeline from being the default, but they reasonably quickly rolled that back. https://www.theverge.com/2022/3/14/22977782/twitter-default-...

Of course it doesn't make sense. I think it's just a dog whistle to the people who believe google have a guy in a room somewhere turning the "conservative search results" lever down a notch during elections.

> turning the "conservative search results" lever It may not have been algorithmic, but it definitely happened.

Yes, irrelevant, and the code somewhere is readable. Take an example like gravity: is there an algorithm for how gravity acts even though it varies per each molecule based on a kajillion other molecules? Of course there is.

If I have your DNA can I recreate a perfect copy of you as you are now including your mind? It is after all the code you were made with.

Nobody is trying to “recreate a perfect copy” of Twitter. Do you think that code which produces random numbers is also not an algorithm because it doesn’t recreate a perfect copy of a previous random number?

For anyone wanting a non-empty version, check out my article on how Twitter's algorithmic feed works from last week https://transitivebullsh.it/oss-twitter-algorithm-part-1

How you _think_ it works from 1000 miles above.

Sort by recent is an available setting. Whether you can keep up with the volume is up to how many people you choose to follow.
