Did they formally update your performance rating? Did you end up getting the raise you were expecting, or did they give an excuse like "well all the raises have been allocated at this point"? The immediate situation sounds like it

Peter Naur's "Programming as Theory Building" is a classic essay, and absolutely worth reading. This transcription [1] (with some extra remarks at the end by the transcriptor?) is pretty accessible. [1] https://pab

One pattern I see sometimes is to define a util class, but rather than having a bunch of static methods, you wrap the underlying object in a util wrapper that adds all of the utility methods. Unfortunately, Java also has no good way to del

A now-deleted (v_v) comment rightly called out that in many languages, method-style invocations are inextensible: a fixed set of methods exists when the class is created, and you can't add any more after the fact. So at some level you&

Apologies; apparently I was thinking of integer multiplication using FFT: https://en.wikipedia.org/wiki/Sch%C3%B6nhage%E2%80%93Strasse... But my question (which wasn't about asymptotic complexity) stands: can we

I'd guess that the "sliding window" metaphor means you could model matrix multiplication as a convolution. Does this give any intuition for matrix multiplication via the Fast Fourier Transform? https://en.m.wikiped

For the teams I've been on, Jira is less in support of team processes and more an excuse for their nonexistence. The following exchange is only slightly doctored: "What are our team processes?" "Oh, we use Jira."

Scrum was effective at my old workplace, but maybe for a bad reason. Almost every software engineer had a time split between at least two teams, usually 50-50 but sometimes imbalanced or split further. Since teams tended to ask as much of y

There's a concept in the research literature called "superoptimization" -- finding the absolute smallest program that meets a given specification. It's worlds away from being used for anything larger than a small handful

Hi HN! This is my first proper foray into longer-form blogging, but I've been too shy to share it around since publishing it. I'm happy to receive feedback; please do try to be constructive, my ego is fragile :)

That said, Spivak's work on framing databases in terms of categories [2] is pretty fascinating, and might be worth poking at. [2] http://blog.ezyang.com/2010/06/databases-are-categories/

I find it most useful as a kind of conceptual organization. It's not something you'd directly solve problems with, but rather a way of organizing your work on the solutions. In that sense, it's much like software architecture

"a call-out" is a very distinct entity from "being called out". Nobody was calling you out ; rather, Dan made a particular point that the author appreciated being raised .

Yes, something like that! Maybe put differently, we all interact with people expecting those interactions to go a certain way. When they don't go as we expected, we often see it as a failing either of the speaker or of the listener; an

At least for me, it's not about whether it's "socially acceptable". When everyone around you tells you you're morally inferior because you can't do the things they can, the way they can, you (I) internalize a h

There are also no deeply invested customers for most FOSS development. It's not really surprising that most FOSS design feels aimless when the developers only need to meet (or aren't funded beyond) their own needs -- the bar is wa
