You're comparing apples and oranges. The cost you're paying Hetzner is not just for the power they are buying from the electric company, but the cooling of that same number of watts as well as other building maintenance, networkin

Large, unsharded services are generally going to run one instance per machine alone as that's the most efficient way to run most of them (reduce per-instance overhead as much as possible). Small (true "micro") services or oth

There is a Hack monolith (the www tier). There are also a huge number of other services, ranging from micro with a couple instances globally to "larger than almost anyone elses's monolith".

(a) make each individual database small, but have a lot of them (b) There are lots of transactions in flight, but there is a well-ordered sequence of mutations (the binlog) that defines what has and has not been committed. So applying a bac

Facebook actually does some compile-time optimizations, but also ships some of the profiling data for JITing between early deploy phases and the rest of the fleet: https://engineering.fb.com/2021/03/03/develop

Stab in the back feels apt for signing something to get money in exchange for not saying bad things, only to go and say bad things once the OP realized there would not be consequences for that.

This isn't anything particularly corporate. If you worked at a mom and pop restaurant and mouthed off with this level of vitriol about the customers you should expect to be fired. I don't think there's any discussion about wh

This is incredible mental gymnastics. Unless it's clear otherwise, especially in public, it's a personal attack.

Yes. There's a difference between saying "I would like to avoid you because your industry costs lives" and "I'd shake your hand, but, y'know, the blood never washes off". They're both basically statem

I'm struggling to think of legitimate questions which would get someone red flagged. Asking about oncall, team dynamics, inter-team dynamics, culture, why people want to work there, etc. all feel like they're important for the can

The comment about concurrency was strange. They have 24 x 5 + 2 x 2 * 60 = 360 writes per minute, or about 6 writes per second. They're not seeing concurrency issues because the amount of time that's spent doing writes is like 1%.

I wouldn't expect details of nuclear enrichment and refinement techniques to be published publicly, just vague bits like saying which elements they were working with.

LC hard shouldn't be needed for almost any companies except ones which are delusional. LC hard are there as practice for programming contests.

That's a pretty big stretch to claim that everything related to emotion is equally suspect. Safety is something which naturally has a very strong perception element to it. A lack of a feeling of safety causes people to change their b

Hook up a heart rate monitor to someone walking down the street on University Ave. in Palo Alto, then hook it up walking down Market Street. Those feelings are real.

Not sure about what's been published, but from what I recall, for data stored in memcache it was manual: people would need to know the right keys to invalidate when doing DB mutations (naturally there were functions encoding this, so m

The situation in question involved a response from some other server. That server was supposed to speak some binary protocol which had a 32-bit length field at the start of the response. Instead the program which did the giant malloc accide

An evaluation for a course should measure how much of the subjects of the course the students learned. It's not a job success simulator, nor a measure of unrelated skills.

An RDBMS is not the best data store for all data. Sometimes flat files or other are the simplest tool for the job, as shown in the article. Adding a database to any of those tools would definitely not be worth the trade-off.

A comment attacking someone for being a shill is expressing skepticism in the most trivial way, and serves to throw a debate into a flamewar rather than actually discussing the flaws of their arguments.

Basically Bluesky is getting to learn all of the lessons about why running a social network is hard, at an extremely high speed, with lots of public scrutiny. Fun.

I still don't understand what you're thinking of as assets vs liabilities for a bank. A bank's assets are any cash it has on hand, plus any loans it issued / bonds it purchased (I think that's what you meant by in

Why is this at all surprising? Banks buy fixed-interest-rate debt/bonds with deposits. Then the fed raises rates by a huge amount quickly, resulting in FMV of that debt dropping significantly, so lots of banks are insolvent if you were

It's not a delusion. From a legal perspective, the bank treats actions which are authorized by you and actions which are not differently. If you enter into an agreement that says you're authorizing entity X to charge you based on
