I think knowledge of the concepts is very useful, but precise recall of the algorithmic implementations is absolutely useless. It’s very different for someone to have a solid grasp of, say, cache-aware programming techniques, algorithms and

Bullshit. It has been my personal experience, and the experience of many people I’ve spoken with, that this kind of trivia is learned in order to get a job and then forgotten immediately afterwards because it’s useless. Anecdotal example: a

I’m gonna be honest this is difficult to parse. I’ve lived here for nearly 5 years now, and it sounds like you’re kind of describing Manhattan in the winter nearly any year. I’ll likely do most of the things I’d do anyway, except I’ll be we

No rent increase + 1 month free (July) + a discount on one month’s rent (August). Amortized over the full 12 month term, it effectively knocks a few hundred dollars per month off of a (very small) one bedroom apartment (with an in-unit wash

I think that even comparing NY/NJ to CA right now makes me slightly more confident that the NY Metro Area will handle a potential future resurgence better. I was out at some of the protests a few weeks ago, and the fact that NYC hasn’t

I stayed in my apartment but negotiated a concession from my landlord to lower the effective annual rent.

I’m 29 and living in downtown Manhattan at the moment. I decided to re-sign for my lease, which would have ended this month, after negotiating some concessions from my landlord. Everyone’s got different priorities, but I enjoy living here a

A WAI `Application` is defined as the following type alias: type Application = Request -> (Response -> IO ResponseReceived) -> IO ResponseReceived ...which is to say that WAI applications are “just” functions tha

I like Haskell, I write Haskell at my day job (and did so at my previous day job), and I help maintain some of the community build infrastructure so I’m familiar with a large-ish graph of the Haskell ecosystem and how things fit together.[0

The inputs shouldn’t be “random”, but the idea is that you should provide an input distribution that’s roughly representative of your expected distribution of real-world values (+ some perturbation to find edge cases). As for frameworks in

This is in constant tension with the point that GP is making though. If you’re not _very_ careful with your software architecture, you can inextricably tie your frontend and backend applications together. Depending on the size of your produ

Having followed the PostgREST project for years, it’s been wild to see the recent explosion of similar sorts of projects (as you describe); I’d very much believed this was a “solved problem”.

I always find this comparison a little... silly? I dunno, there’s probably a better word, but I can’t think of one right now. Nix focuses on reproducible build declarations and development environments, while Docker focuses on self-containe

Steve Klabnik and Sean Griffin were both early adopters of Rust (and are now fairly visible members of the community), and I believe that helped sow the seeds of the language in parts of the Ruby community [0]. I think Rust managed to also

Ha, TIL! I’m not too familiar with the Long March family but that does make sense. More random engine nerdery: - It’s really exciting to see all of the development going into full-flow combustion metholox engines these days; BE-4 and Raptor

Regarding hypergols, I love the fact that you are absolutely correct that they’re mostly relegated to places where you _need_ autoignition these days, but then you look at the Proton rocket family... https://en.wikipedia.org&#x2F

I don’t see how “political correctness” is a factor in this analysis. It sounds like socioeconomic status is correlated with race in America [0], there’s a strong correlation between one’s socioeconomic status and one’s ability to enforce s

You can work around this in the event that your commercial software provides a consistent interface for the license key stuff; e.g. via the CLI, a key file (ideally plain text) on-disk, or some scriptable interface. Then you can store this

In practice you can actually get extremely close to having Nix manage your whole macOS system with the exception of actual OS-level updates (and particular tools like Xcode, I suppose). John Wiegley’s system configuration [0] is an example

The author’s rhetoric is likely the cause of the downvotes, in particular focusing explicitly on “undocumented immigrants” when there seems to be no evidence that this group of people presents any greater (or lesser) risk than other groups
