The issue tracker and pull requests are being hit with very funny suggestions. Many people suspect this is an April Fools joke. It's possible this entire repo was generated by a LLM to appear plausible.

I especially like the suggestions to rewrite the algorithm in Rust [1] and this pull request which simplifies the algorithm to a single c file [2].

Elons reply “I only learned about it now!”. What a crock of shit. We literally went through reporting a few months back where he was clearly instructing the team to make sure his tweets always come up, for everyone.

> We literally went through reporting a few months back where he was clearly instructing the team to make sure his tweets always come up, for everyone. Feel free to give me a source for that, but I'm pretty sure that's not true.

It was widely reported in the days following the Super Bowl that he personally ordered his Tweets be boosted after a Tweet by Biden got more engagement than his similar Tweet [0].

As far as I can tell, he did not instruct Twitter employees to make his Tweets appear to all users, but he did want them to make his posts appear in timelines significantly more often. This lead to reports of users suddenly getting their timelines flooded with lots of his Tweets.

It seems like there was a rush within Twitter to raise Musk’s engagement numbers by altering the recommendation algorithm to specifically boost posts from his accounts. The special boost factor was later reduced, but allegedly still exists.

It's disappointing the comments are so obsessed with the political angle to this that there's a total lack of appreciation (or discussion) of opening up the most influential social media platform in the world.

I had to go to the second page to find this. I completely agree. I clicked this thread looking forward to seeing some intelligent discussion of the merits of the source and issues/interesting tidbits, instead I see a bunch of Elon Musk ranting and complaining and pointing out drive-by poor pull requests issues. I really wish the adults would start to talk.

Parent didn’t say it’s not “political”. It’s reasonable for a wealthy person to feel that a system that discriminates against the poor is not a system they want to participate in. (Note that I use discriminate in the literal sense, as a simple statement of fact.)

lol you don't actually believe that's his reason do you?

LeBron started a school where poor kids can get free food and clothes. The man obviously cares.

Great! But nothing is going to change until people realize that the problem is the feedback loop . It's not the recommendation engine itself, it's the fact that there's no way "out" of the feed that the engine produces. It recommends you stuff, you have little choice but to engage with it, and then it trains on that information . This is the problem with most of social media today. It is a very well known problem in…

Thank you! Working on a concept for a big org on what may become a large ML-based system one day. I knew about this feedback loop issue, but was too dumb to actually remember and face this problem. :) It's all over today's rec engines -- and yet, just like the things we're not shown in these systems, the problem itself seems to become invisible. Because it requires new thinking. Worth exploring.

Reddit is a good example of an alternative system, and it works because subreddits serve as lower-variance composable streams as well as shared digital spaces. Even though your main feed is partially driven by a recommendation engine, it never contains any content that you didn't subscribe to (ignoring ads, of course). Instead, you may see a "posts from other subreddits" section that breaks up the feed explicitly to offer alternatives. If you're interested in a particular topic, you can drop into that subreddit, where you'll see pretty much the same view as everyone else. In all these cases, you're always in control.

I wouldn't be surprised if Reddit actually has the best data on their user's preferences, because they let them explicitly decide what they want rather than playing this "hot and cold" game like TikTok. Those platforms also only let you subscribe to individual accounts, so they have to infer what your interests actually are.

I would agree the quality of posts has gone downhill, and is way too political for my liking, but there's not much other place to go that isn't elitist.

Discord. As much as I hate Discord the platform (and I really do hate it, far more than, say, Twitter), Discord does have a lot of good communities.

I've found Discord worse in every way. Almost every server I've been in is highly reactionary to any kind of accidental phrasing. Walking on eggshells is a constant process in any Discord server. It also descends into the same type of problems as any other chat services as it encourages short messages rather than long well-thought-out posting.

It is really nice to see how bazel is used in the wild. It looks so clean. Why we are not using it for everything?

I wouldn't want to use a build system written in Java for non-Java code. Adding the whole JVM as a dependency just for the build system isn't worth it,

This speculation seems mostly informed by a negative opinion of Elon. Is there any real indication he gave this instruction?

Yes that weekend everyone started seeing Elon's tweets in their timelines: https://www.theverge.com/2023/2/14/23600358/elon-musk-tweets... You seem weirdly protective of Elon fyi

And Elon later explained that that had nothing to do from him making any specific request that his tweets be valued.

This is largely a false creation without evidence to back it up. People are assuming intention behind something that's much more easily explained as a bug, one that was quickly fixed. If it wasn't a bug, why would it disappear if people assume Elon is narcissistic as people claim? It'd still be prioritizing his tweets if it wasn't a bug.

As if Elon has a clue what that feature is or is not being used for.

He didn’t say he knew what it did? It’s a good enough response to say that it shouldn’t be doing that period.
