You may already realize this, but you don't need to run a VM per project if you're using Nix; Nix lets you have as many self-contained development environments as you like, all on one machine without VMs or containers.

Yeah, I think the easiest way to test that Service A is meeting its API obligations is to send some requests to Service B. Hyrum's Law means that that's the only way to really test the important aspects of Service A's API. An

Your comment matches my experience very well. I had the same experience as GP and OP with low-quality e2e tests at my job. I got fed up four years ago, started something new from scratch, and now I'm the BDFL you mentioned, for a bunch

Compare it to unsafe functions. An unsafe function can be called in an unsafe block or an unsafe function. Rust could require annotating each call to an unsafe function, even inside unsafe functions. Why don't we do that? That seems li

One sad aspect is the ? operator. In the beginning, Rust thought it could get away with explicitly handled return codes, without having support for direct style/exceptional error handling. But they've ended up with that in the end

The analogy is fun, but I'm not sure I agree with the author's conclusion: > a constexpr marker should be unnecessary, just like a hypothetical linux marker In fact, I'd love to have a "linux" annotation for func

The FSF has made no such statement. This article is complete bullshit and a slanted quote. The FSF said it was unacceptable because it's proprietary, like Github in general. They've made no statement about the specific details of

From the git repo history it looks like the original name was "Loc", for "Language of Composition".

Er, just as a historical note, one of the primary uses of chroots was for packaging. Just like how Docker does it. That, in a sense, was even the original motivation. The security usage of chroots was a later innovation.

Use NaCL or other SFI techniques. It doesn't require any kind of serialization/deserialization code, contrary to your suggestion. Here's the original SFI paper, maybe it's more approachable? https://cs155.stan

Sorry, I responded too quickly to this comment: >- Libraries often CAN'T be written in a separate language without an additional effort -- and often writing with interop in mind means you have to give up nice features like C++ STL c

Great comment! I've added points about most of these to the post. But just to respond quickly to these directly: - Writing in a single language, not multiple languages which requires you to speak IPC protocols, is the whole point. - Ad

This article doesn't really back up its contention that "Internet" is a bad name. It says, briefly: >Some of us call the whole thing The Internet, when technically, the internet is — as once unfortunately put — a “series o

As an alternative, there's no reason why one couldn't use neovim and magit (using Emacs only for magit). Emacs is an application framework, there's no reason why one has to use the "editor" application if all you wa

I loved Stockfighter. I played through it as preparation for starting my first job out of college, at an HFT. No comment on whether it was good preparation. :)
