The peculiar viewpoint you’re demonstrating in this comment is similar to Reddit’s. It’s not objectively wrong , but the calculus involved definitely looks weird from the outside. How would you quantify the value of Hacker News to Y Combin

I don’t think you’re misunderstanding anything, but to clarify, I’m talking about a more general notion of subtyping (e.g. structural, “duck typing” etc), not necessarily inheritance. Instances of A and B can (in Smalltalk parlance) respond

> My question is, why is that necessary? Exactly what is the benefit, except for a tiny bit of convenience? Why is that better than functions that work on well-defined types? The benefit is subtype polymorphism via dynamic dispatch. When

It’s hard to generate efficient code ahead-of-time because the compiler doesn’t know what the types of values will be, so it has to emit very general code that can cope with all possibilities at the expense of performance. A just-in-time co

True enough. I think when we say “simple” we often really mean “cheap” (to maintain), so maybe it’s better to cut to the chase and just say that instead.

I agree with what you mean, but I’d nitpick and say it’s not the code itself that’s the asset, but rather the behaviour of that code when executed. If you could refactor and get the same behaviour with less code (whatever that means), that’

You’re describing people who believe that code is an asset, when the reality is that it’s a liability: zero lines of code would be ideal if you could get away with it, but you can’t, so you have to compromise and limit that liability as muc

For better or worse, the convention in Ruby is to name methods in a second-person style [0], as if addressing the object directly: “file, do you `#exist?`”; “string, do you `#start_with?` foo?”. So, for consistency, `Dir.exist?` and `File.e

The endpoints of the lines have subpixel resolution, so although you’re only drawing whole pixels, the choice of which pixels to draw along the line may change based on the subpixel positions of the endpoints.

This was, for me, not an effective demo: when I tap “sign in with a passkey” it shows me a QR code to scan with another device. What? (I assume this is because I haven’t created an account yet, but if so, the demo needs to make that about t

I know what you mean, but — as the article explains [0] — Git’s packfile format uses delta compression, which is essentially “storing diffs”. [0] https://github.blog/2022-08-29-gits-database-internals-i-pac...

A complex number represents a 2D point in the complex plane, but multiplication by a complex number on the unit circle also happens to correspond to a rotation in the complex plane, e.g. 3 × i = 3i, which is a rotation of 90 degrees antic

This is incredibly clever. In case anyone else is confused by the order: the ASCII codes for L, S, R are 76, 83, 82 respectively, so L encodes i and R encodes -i as you’d expect.

I do find “BDD” a frustrating term. It was coined by Dan North [0] to refer to a coherent set of sensible TDD practices — give tests expressive names, say “behaviour” not “test”, write executable “given/when/then” acceptance crite

I have neither the motivation nor the energy to start an internet argument about it, but I’d like to reassure the casual reader that this post is promoting a minority viewpoint.
