I think this depends on the library. There are some libraries that are just used in a handful of services, and in those cases I don't think that wrapping is worth the overhead. However for some of the core platform functionality depend

There was previous discussion related to our microservices architecture here: https://news.ycombinator.com/item?id=22725989 .

I think we've gone back on forth on this over the years. The rate of new services is decreasing, so I think we have shifted more from lots of very small services (low thousands lines of code) to bigger ones that are more like an entire

This is a potential downside of this architecture. As others have already said, there are mitigations, but fundamentally each edge request is going to be more costly (time or money) to serve than having it served by a single machine/DB

I think the other responses have explained the definition I had in mind for "anti-value". "Frugality" is a bit less explicit than "move fast _and break things_. I think the reason it could be considered an anti-valu

Thank you for raising the point about contradictions in values. I tried to work it into the original blog post, but I felt like it detracted from my main point. I previously felt these contradictions are problematic because they make it har

I see this sentiment a lot in the Go community. I think it is reasonable in some cases, but there are many use cases (vanilla CRUD web apps) where a web framework is really helpful. The standard library is very low level. Want sessions? DIY

I think what is often missed with values, is the "anti values". Often when I see a list of company values, it looks as if they can have their cake and eat it too. They are not explicit about the trade offs being made; e.g. "m

It's a shame -- and slightly surprises me -- that ITAR applies to roles like this. Does it apply to entire orgs, or is SpaceX to small to be worth the trouble of creating separate legal categories of employees?
