The article is great, sorry for the quibble! The maybe too subtle point I was trying to make is that, even though the TypeChecker object literally provides an EmitResolver (I think? something like that?), in terms of the conceptual layout o

This is a bit misleading in where the "Type Checker" box is pictured, but I think it's due to an understandable confusion about how the compiler is structured. Importantly, types do not affect TypeScript emit [1]: you can ta

I read about stack graphs before, it sounds interesting! I think they help, but ultimately I expect you need a compiler solve the absolute madness of the totality of C++. For example I think getting argument-dependent lookup right in the p

I contributed to a similar system used within Google (partially open source at kythe.io), that took the very different approach of integrating with the language-native toolchain for each language. As this article describes, doing this requi

(n2 author here) ETA is pretty hard in the presence of parallelization unless you make big assumptions like "all pending build tasks will be able to run in parallel". If you had any good ideas here I'd love to hear them.

(n2 author here) This is really cool! I am sorry if weird ninja decisions (like not being lexer-friendly or phony being underspecified) caused you grief, the whole thing was really built as a quick hack before I understood the problem spac

In Ninja, which needs to spawn a lot of subprocesses but it otherwise not especially large in memory and which doesn't use threads, we moved from fork to posix_spawn (which is the "I want fork+exec immediately, please do the smart

I love Factorio! If you've completed enough of the base game, I can recommend Seablock (which includes AngelBob) and Space Exploration as two mods that make the game dramatically larger. I played some of Pyanodon (which is also someti

I don't know the history, but I think Figma predates much public knowledge about Skia. Further, I have the impression that Figma has pretty specific and complex graphics needs. For one example of the sort of thing I mean, we decode im

Yes, sorry! I should've written GL, not GPU, but it's too late to edit it to fix. ...though there are some shaders involved.

> Figma makes use of a low-level C++ library called Skia for 2D graphics rather than building their own graphics engine This is not quite right. The bulk of Figma rendering is Figma-custom GPU code. It's true that Figma uses Skia,

At least as of >10 years ago when I worked on the code, the equivalent feature in Linux Chrome uses a unix socket in your Chrome profile directory. It was a little subtle to implement in that you need to also handle the case where a cra

My recollection is that you need a license to PDF patents from Adobe to implement those things, and Apple is somehow grandfathered themselves into those licenses via NeXT. (But upon writing that I'm not sure where I got that impression

As a person who enjoys doing this kind of cleanups, it is disappointing. But when I think of the larger business perspective, these kinds of cleanups are difficult to justify, in that the value of them is hard to quantify. Overall the net

To prevent these kinds of bugs, the iteration order in a Go map is randomized across each execution.

Chrome originally integrated RSS feeds in the new tab page, to show you when there were new posts on sites you frequently visited. We cut the feature just before launch, because it wasn't fully baked, and never resurrected it. (I know

I noticed that the two bugs they linked [1] [2] are both due to the distros introducing bugs by applying patches -- one for hurd support (!) -- that were not shipped by the upstream projects that the distros were repackaging. As we have di

It's not, I linked the patch. (I don't fully understand the patch so I'm happy to be corrected here, but it looks like it was an ordinary "use atomics incorrectly" bug.)

It's interesting, I read this and had the opposite conclusion -- people are still writing racy code using Rust. I mean, it's great that you can write threaded code with more confidence, but it seems the conclusion here is that Rus
