In part yes, the difference is the ability to access the 64-bit registers, the additional set of registers, and the assumption that SSE is present. But because of all of these, x32 defines a new call convention to optimize function calls.

A couple of things I'd suggest: * Clearly delineate what is on-call work and how many people pay attention to it, and protect the rest of the team from such work. Otherwise, it's too easy for the team at large to fall prey to the

I actually archive any sort of short-form writing that I think is valuable in my site :) In fact, I compose Twitter threads first as a regular post where each paragraph fits in a tweet, then copy/paste those onto Twitter, and then shar

Nice presentation and nice recap! A couple of observations from the text that resonate with me: * "Blogging helps me become a better writer, which in turns helps me become a better developer." Yes. Writing is super-important as a

Luckily, the company at play does not require an explanation to use containers on developer machines. But when you are in charge of a remote execution service, CI pipelines, and production builds… well, this is not about a single developer

OP here. I did not touch upon CLI argument handling in this article because I wanted to focus on the kernel but this is indeed a big difference. And... I had written about this too :) https://jmmv.dev/2020/11/cmdli

Sure, if you have the luxury of having a functional IDE for all of your code. You can't imagine how much faster I was than everybody else at answering questions about a large codebase just because I knew how to use ripgrep (on Windows)

Nice. I wrote about a similar idea back in 2013 ( https://jmmv.dev/2013/07/readability-explicitly-state.html ) after I found that being explicit about all branches made my code easier to reason about and easier for

Sourceforge had a flat namespace for projects and required you to manually apply for each project. It was a PITA and that added a huge barrier to entry. Plus it didn’t have a mechanism to send contributions. I think GitHub “won” because of

Nice project! I recently did something similar by porting the EndBASIC console to show up in a tiny LCD. Making it work at all was fun, but then optimizing the driver to be fast enough was a really cool exercise. I've submitted the sto

Oh that’s right! We had to use LGL in addition to geolocation to lay out points without data. And yeah, the geolocation came from some internal service. Thanks for chiming in. Good times!

Reminds me of the intern project I worked on at Google back in 2008. My mentor at the time had a traceroute dataset of the Internet and wanted to render it on top of Google Maps. I implemented a MapReduce algorithm that geolocated the data

It’s a nightmare only if you think of the monorepo as just throwing everything in one place (aka just a technical choice). A monorepo requires org changes. It requires staffing teams to handle processes and tooling for everyone else. (And i
