This depends a lot of what you are using exceptions for. I think in general the branch on Ok/Err is probably not meaningful performance-wise because the branch predictor will see right through that. But more generally the happy-path&#x

Happened to me. Bought a house with wood floors in the basement. We had some flooding which ruined the wood and when we ripped it out to replace, turns out the wood floors were installed over the original asbestos tiles. From what I can tel

Trump is definitely the most egregious by a very wide margin, but the pardon power has been abused by every President in my lifetime. It's a truly insane feature of our constitution that needs to be changed.

I interviewed with Amazon a few years back. The whole thing turned me off. A recruiter reached out and I was interested (it was late 2020 and the money was tempting). But before the first phone screen I had to have a call with the recruiter

How does this work in two-party consent states. IANAL but as I understand it, you need to permission to record someone in California. As an aside, I don't consider myself a particularly paranoid person (relative to the median HN commen

Sure, any program can have bugs. The point though is that it is "just a bug" and not UB.

The main reason is that arrow files are not compressed at all. So storing everything as Arrow would increase storage size by 10-100x (depending on data)

I took the article to be saying that mpmc queues are not queues so we can use bags instead because bags are faster. The second claim seems dubious to me though. I checked out the repo which led me to https://alexsaveau.dev/b

I read this article earlier today and ended up going down a rabbit hole trying to figure out what Xanadu actually "is" (on a more technical level) but haven't really been able to find much. Does anyone have a good resource fo

The basic tradeoff is that you are paying an extra tax on all requests that are not served by the cache, so you something like this would help if you are reading the same data repeatedly. So, for example, a database built on object storage

I'm not a fan of tipping in general, but as an American who has spent a lot of time in Europe, my experience is that the level of service in American restaurants is quite a bit higher than in European ones on average. That's not t

My personal pet theory (based on no evidence other than personal experience) is that, if your job is in senior management then your day-to-day work is going to meetings. And spending 8-10h on zoom meetings every day is unbelievably soul-cru

Yeah, back when I used to swim a lot I could never find anything that was any good at tracking swim distance either in a pool or open water.

Sure, you just have to balance that against the cost of a poorly specified API interface. The errors because clients aren't clear on what is really required or not, what they should consider an error if it is not defined, etc. And of c

But this is something you should be able to handle on a case-by-case basis. If you have a type which is stored durably as protobuf then adding required fields is much harder. But if you are just dealing with transient rpc messages then it c

If you need to deserialize an old version then it's not a problem. The unknown field is just ignored during deserialization. The problem is adding a required field since some clients might be sending the old value during the rollout. B

Support across languages etc is much less mature but I find thrift serialization format to be much nicer than protobuf. The codegen somehow manages to produce types that look like types I would actually write compared to the monstrosities t

by thinkharderdev 1y ago
Yeah, as soon as you have a moderately complex type the generated code is basically useless. Honestly, ~80% of my gripes about protocol buffers could be alleviated by just allowing me to mark a message field as required.
