Copying over my latest backend status update; figure folks would find it interesting

Servers are holding up so far! Fortunately we were overprovisioned. If we hit 4mm new signups then things should get interesting. We did have some degradations (user handles entering an invalid state, event-stream crashed a couple times, algo crashed a couple times, image servers hit bad latencies) but we managed to avoid a full outage.

We use an event-sourcing model which is: K/V database for primary storage (actually sqlite), into a golang event stream, then into scylladb for computed views. Various separate services for search, algorithms, and images. Hybrid on-prem & cloud. There are ~20 of the k/v servers, 1 event-stream, 2 scylla clusters (I believe).

The event-stream crash would cause the application to stop making progress on ingesting events, but we still got the writes, so you'd see eg likes failing to increment the counter but then magically taking effect 60 seconds later. Since the scylla cluster and the KV stores stayed online, we avoided a full outage.

It's frustrating that anything related to X/Twitter is such a predictably-partisan tinderbox because this is really interesting technical information. Thank you for sharing it!

It's partisan/political because Musk is partisan/political. And it's not just Musk.

We've been living in a fantasy land of "no political affiliation" in the tech world for decades, and now that the age of the hyper-rich has come once again, they are realizing the benefits of using the power they wield to shape the worlds they live in.

So now in the early stages of this century's great fight, we'll see our beloved tech giants join the political fray in full force, dragging their follower armies along for the ride.

And it works, too. Just look at the comments here.

Looking at the responses, I can see that people are still viewing this through the limited lens of left vs right.

This is of course a thing in that nobody can hide their colors anymore, but I'm specifically talking about the rich now feeling empowered enough that they even have the hubris to challenge governments of the world for their own benefit, and in some cases even build their own empires to escape the limitations of governments by forming their own rich-people-only worlds.

For example: https://www.nytimes.com/2024/08/28/magazine/prospera-hondura...

So long as you continue fighting left vs right, you're fighting the wrong enemy.

As an outsider, I can't help but feel that the American election system that boils everything down to just two parties imposes a limited binary lens onto at least the American view of the world.

It happens in multiparty systems as well. All it takes is a significant portion of the population feeling like their voices are not heard, and then one of the parties taking up their banner as one part of the overall campaign (which doesn't even have to be in their new constituents' interests).

This is happening all over Europe as we speak. And even though it happens to be extreme-right atm, it doesn't have to be. We've seen extreme-left revivals in the past as well.

And Europe is actually resisting better than US due to election system. Here in best case scenario they are number 2, and took them a long time to get there after Trump

In the US, a populist just needs to win a primary, ie 50% of 50% of the American votes, and he is immediately at least nr2 in the run, and they get the support of one of the major parties.

Saying that populists / extremists also exist in Europe is just a bad comparison.

The extreme right won the Dutch elections though - and they’re not the only country - so your argument that “best case (...) number 2” isn’t true. They can and do win elections.

What did winning mean, though? Is it Republican-style minority rule where they can work the system push through policies which a majority of Americans oppose, or a coalition government where half of his coalition is pledged to rein in his more extreme positions?
