This is neat! If you're interested, Ninja ( https://ninja-build.org/ ) is designed exactly to provide the dependency-graph execution underneath a program like yours that has a project-local higher-level description of t

The line I linked to, sure. But under what conceptual model would a framework need logic to strip comments (an aspect of source text) at runtime? Follow it to its conclusion.

I am often frustrated in this ecosystem by how people build things without any clear conceptual model, and then they document them by saying "it is so fast, it just works like magic". It is impossible to compare two approaches be

Can you elaborate on the difficulty on Windows? If you go to the home page there is a section "Getting Ninja" that links to a page with a zip file... ?

We first started fiddling with Clang for Chrome in late 2010: http://neugierig.org/software/chromium/notes/2011/01/clang.h... The original work was just finding bugs in the codebase and compiler. I

Can Nix build incrementally? One random collection of notes I just dug up says that it rebuilds packages from scratch on minor changes. It seems like Nix is addressing a different problem.

Hey I worked with Jim! Fun story: a project we worked on together involved some Python and he suggested that he didn't really know Python. At some point I somehow noticed that he wrote the Python profiler (see the name at the top htt

I wrote some similar bugs to this in the complex text handling in Chrome. In text layout you do a lot of indexing into various arrays -- like the array of code units of the input string, or an array of metadata collected per-code point, or

(Disclaimer: haven't worked on Chrome in ~7 years.) This weird hashing scheme comes from safe browsing (which blacklists sites that install malware etc.). I guess (without specific knowledge of it) it was just reused for this ads thin

My wife is a dentist so, using similar reasoning, I once asked her why people don't do this. She said the problem is that implants ultimately connect into bone and that connection fails over time -- your body is designed to renew the

For Chrome we had to go through a lot of extra effort to make updates not break us. http://neugierig.org/software/chromium/notes/2011/08/zygote....

Just to second this point, I am often courted by potential startup employers and I am usually pretty skeptical for exactly this reason.

Also noteworthy: the Apache 2 license, which includes a patent grant (unlike the previous Facebook licenses that have caused concern in the past).

I think type info in TS is 100% gone in runtime. Here's a blog post that explores why you can be confident of this: http://neugierig.org/software/blog/2016/04/typescript-types....

The TypeScript compiler is the canonical corpus of code written by TypeScript experts, and I learned a lot of interesting style from the time I've spent with it. (Fun fact: they don't use 'class' in the compiler at all,

They are following semver: http://semver.org/ So the major version changes whenever they make a backwards-incompatible change. However, I clicked in their upgrade calculator (linked from the post) and at a glance it appears

I wish the HN community would collectively decide to downvote posts like these, which reward people who use clickbaity titles to get attention at the cost of hiding more careful analyses. The post can be summarized as a critique of a progra

The comment "Welcome to the club. I did this years ago." in isolation contributes nothing to the conversation. If you had posted it I probably would've downvoted it for that reason, not for the smugness.

In this thread: people will bring out the same tired arguments for or against static typing, without commenting on the actual content of the post, which was quite good! I have come to see type systems, like many pieces of computer science,

I think the web is the lone exception. Consider the other big software platforms from the last few decades: Android, iOS, Java, Windows. The trend is adequate-but-not-exceptional tech with rich companies pouring cash into their success. (

Though I disagree with many of the points made here, I love that this person is taking a position and putting in the real work to to lay out his argument for it. I think the main point he's missing is that most platforms die due to lac

I bet there are a few security vulns lurking in games that involve user-provided data (e.g. maybe you can customize your clan by uploading a logo). The boundary between trusted and untrusted in games with mods is especially porous ( e.g.

I suspect one factor for why Go is so popular within Google is that (due to complex path hacks as mentioned here as well as a network file system) Python startup is so slow. On an app I worked on the unit tests took >10 seconds to boot o

I work on TypeScript at Google, so just one point about scaling. Ultimately the only way to make things scale to large codebases is to make separate compilation work. That's what we do: separately compile separate pieces of the codeb

I think WASM is great, but it also is not a panacea. You can see this demonstrated in their demo where highlighting the text garbles it -- because they render without using browser technologies, they miss out on browser implementations of t
