You may have heard that TypeScript has been taking the web development space by storm in the last few years , bringing to it static types. I believe the same thing is starting to happen in the world of Python, where type checkers like mypy , Pyre , and Pyright are increasingly used, at least where Python is used by…
TL;DR ¶ Some of the wisdom contained in Josh Bloch’s Effective Java book is relevant to Go. panic and recover are best reserved for exceptional circumstances. Reliance on panic and recover can noticeably slow down execution, incurs heap allocations, and precludes inlining. Internal handling of failure cases via panic…
The prefix kwarg that most compiler check functions support now accepts an array in addition to a string. The elements of the array will be concatenated separated by a newline.
On May 17th 2019 Google announced Kotlin as the officially supported language for Android, in a long awaited development. Find out more about this shift here.
I have a theory that a grave mistake was made in 1995 - the decision not to have a neat, succinct and declarative way of representing html elements in javascript. [On reading the hacker news comments this is pretty historically inaccurate, however, I think this article still stands as "look just how close javascript…
We replaced simple websites with complex apps nobody asked for. Now it takes a complex build pipeline just to change a headline.

The C strcpy function is a common sight in typical C programs. It’s also a source of buffer overflow defects, so linters and code reviewers commonly recommend alternatives such as strncpy (difficult to use correctly; mismatched semantics), strlcpy (non-standard, flawed ), or C11’s optional strcpy_s ( no correct or…
I’ll start by saying that this is not a rant, but rather a cry of despair that I’m repeating and that slowly - but steadily - seems to come to consciousness in our industry, like this one. The phenomenon I’m about to describe is not only limited to the Javascript community either, that community seems a lot more…
There's nothing here. The Internet is far too dangerous right now. The blog may return in future, if I get around to it.
It’s been about a year since I’ve started using Elixir. Originally, I intended to use the language only for blogging purposes, thinking it could help me better illustrate benefits of Erlang Virtual Machine (EVM). However, I was immediately fascinated with what the language brings to the table, and very quickly…
One thing that works well in practice in cases where you really don’t want to process single bytes at a time is to use a union for going from one type to another. Granted, writing one member of a union and reading from a different one also isn’t allowed per the standard, but every compiler I’ve come across allows it…

Meson's Xcode backend was originally written in 2014 or so and was never complete or even sufficiently good for daily use. The main reason f...
Thanks to Nikhil Benesch, Justin Jaffray and several decades of "wouldn't it be nice if..." for contributions.
I feel like I got substantial value out of Claude today, and want to document it. I am at the tail end of AI adoption, so I don't expect to say anything particularly useful or novel. However, I am constantly complaining about the lack of boring AI posts, so it's only proper if I write one.

With last weeks C++ committee meeting in Oulu, C++17 is feature complete and on its way to become an international standard. After the last meeting in Jacksonville I had little hope to see big surprises, but Oulu managed to add a few important and interesting features to the new standard. There is a very good overview…
Most people use the mattn/go-sqlite3 package to interact with SQLite in Go. This package uses cgo and bundles the SQLite C amalgamation files with the Go source.
Learn Ruby metaprogramming: call methods dynamically with send, define them at runtime with define_method, and handle missing calls with method_missing.
Luke Page has a great post up with his list of YAGNI exceptions. YAGNI—You Ain’t Gonna Need It—is a rule that says you shouldn’t add a feature just because it …
One year and a half ago, an important part of FFmpeg developers decided to change the way the project was managed. This led to some kind of takeover , mainly to get rid of the old maintainer dictatorship, but also to change development methods, redefine objectives, etc. Then, for various reasons I will quickly…
