I worked on JS infra for Google. One thing we found in this space is that when your apps get very large in terms of number of source files, there is a developer-impacting load time cost to the unbundled approach. That is, your browser load

A long time ago I wrote a toy IMAP client, and ran into similarly confusing issues about how the protocol is supposed to work: https://github.com/evmar/go-imap/blob/master/imap/doc.go

https://docs.kernel.org/x86/orc-unwinder.html (which I found when looking up ORC, as mentioned in this thread) has some stats for the Linux kernel on the cost of frame pointers: "5-10%" and "3.49% more c

If I reflect over my life, what has worked is being open and showing passion at every opportunity when meeting people. Most will respond as you’ve described, but with enough rolls of the dice you’re more likely to have a lucky hit. It can

[ninja author] Ninja build targets in a semi-arbitrary order: the memory order of the pointers to the objects representing the build steps. This was chosen in part because it was easy but also because it was a little unpredictable (in the

[former Googler] Yes, I occasionally saw people get highlighted for making optimizations like "this saves 1% in [some important service]". When you're running millions of machines, 1% is a lot of machines. However, it'

English is terrible for sure, but this comment is pretty funny to compare it to the language that spells /kɛs kə sɛ/ as "qu'est-ce que c'est".

Not to defend snap, but I worked on Linux Chromium wrote this about why the apt/.deb model is difficult to make work reliably: https://neugierig.org/software/chromium/notes/2011/08/zygote...

To be clear, I think many developers are comfortable enough with the small handful of commands most regularly use. For the more advanced case of maintaining a fork of a high-velocity codebase like WebKit, it's likely you'll need

We had a similar rotation on Chrome team for merges from WebKit (pre fork), and it was similarly a lot of work and clunky tooling! A few times in my career (including this one) I have thought, "We are sure going to a lot of effort to m

I didn't have any particular expectation when I opened up this link, but because I was curious about the authors I clicked on one and found they had also published one titled: "Evidence for a connection between coronavirus disease

Congrats on making the release! I glanced through the docs and it seems Beast works via a graph over targets and mtimes? I recently wrote some retrospective notes about build system design in this area that seem like they might be useful f

The other inaccuracies in this article have already been covered. I noticed there was also a weird rant about mimalloc in there ("For some insane reason, mimalloc is not shipped in Visual Studio"). My understanding is mimalloc is

Thank you for explaining! I think the piece I was missing is that the sigint handler is passed the instruction pointer of the faulting instruction.

The comment I was replying to made statements about both Java and JavaScript, so my questions were also about both (and whether they were different). I just added a line break to make this clearer.

[author here] Very interesting, do you have a reference on how Java implements this? I just poked at v8 a bit and they seem to have an explicit 'null' object in the VM, though I don't know a lot about so it's possible it

Thanks for this comment. In a previous draft of the post I had more about this, but I decided to omit it because I didn't have much insight about it beyond some handwaving around how it's just encoding the instructions and the op

`static` also allows it to optimize, and it's more of a code hygiene thing. Your original code as written unintentionally defines `find` as a function that must be preserved (as a separate function) into the compiled output, and `stat

The kind of isolation in the post, where the web content doesn't have access to system resources, was part of the original Chrome release. (You mentioned site isolation, which is a different feature, but the dates you have look right f

As a person who likes Go a lot, and who finds Go bashing -- and really, bashing in general -- pretty tiresome to read, I thought this was a pretty decent article and the sort of thing we ought to encourage on HN. At least in contrast to th

(I work on Figma's renderer, but I don't know much of the history of it.) The speculation there about C++ vs JS performance in Figma seem about right to me. Notably, some Figma views (like when you click the "play" butt

The "use ASLR for random seed" trick in there is pretty cute, but I noticed it will just silently not work in non-ASLR settings, and in particular under Wasm.

I had typed out my comment already but it's basically identical advice to this one, so I'm going to move it here as a way of just emphasizing the above advice! --- If you're on HN it's plausible you're advanced rela
