Summary In this post I’ll go into detail about how, during my contracting work for Shimmer Industries (a company founded by Eskil Steenberg which is focused on developing a real-time lighting designing software), I worked on a piece of software which enabled us to use the MacOS and iOS APIs using a custom C API…
Specify UTF-8 as the default charset of the standard Java APIs. With this change, APIs that depend upon the default charset will behave consistently across all implementations, operating systems, locales, and configurations.
In this post, I’ll iteratively optimize an implementation of matrix multiplication written in CUDA.My goal is not to build a cuBLAS replacement, but to deepl...
As of today, NVK is now an officially conformant implementation of the Vulkan 1.0 API on NVIDIA Turing hardware.
When I first learned about Fourier series and integrals, I hated it because it seemed like a collection of many ad-hoc definitions, formally related but very different.
When programming in Go, the amount of error handling is something that slaps you in the face. Most API’s you deal with will expose errors. It can become overwhelming, but with a few tips and a guiding principle we can make handling errors easy, keep our code clean and give you the confidence that nothing is breaking…
I've experienced first-hand how using UUID hurts the usability of computer systems, and I want you to understand why you certainly don't need it.
Does Python still have a need for class without @dataclass?
You can now use Node.js built-in modules like `node:http` on Deno Deploy, allowing you to run existing Node.js apps at the edge.
In the last few months, I started geeking more about aviation-related topics. Mostly by watching A LOT of videos explaining how things…
Calling hell from heaven and heaven from hell is a classic paper from the previous century, introducing the Haskell foreign function interface (FFI). It describes the facilities that Haskell offers for calling functions written in C (and vice versa). In this blog post, we will consider how to call functions written in…
Learn how to use to_form/1 and LiveView Streams to create a dynamic list of forms.
Deno KV, the easiest way to add a strongly consistent database to your app, is now in open beta.
How to implement event sourced workflows?
In a previous article, I introduced what is new in SQL:2023. Now I want to show the status of SQL:2023 support in PostgreSQL. See the previous article for details on these features.
Open a Unix or Linux terminal emulator. If you have Terminal.app on macOS, ensure that the "Use Option as Meta Key" option is enabled in its "Preferences" section. Now type foo bar baz followed by meta + b (i.e. alt + b or option + b on modern keyboards). In a typical desktop environment with a typical and modern…
Xe Iaso's personal website.
Though most strings online today follow the Unicode standard (e.g., using UTF-8), the Latin 1 standard is still in widespread inside some systems (such as browsers) as JavaScript strings are often stored as either Latin 1, UTF-8 or UTF-16 internally. Latin 1 captures the first 256 characters from the Unicode standard…
A rough edge with promises that can sneak up on you.
Design-by-Contract's invariant attribute allows you to enforce important properties of systems and data structures, making it an incredibly useful tool for developers. In this blog post, we'll be exploring the development of a GCC plugin that adds support for [[invariant]] conditions in C++ classes and structs. We'll…
One thing I wish I had understood better earlier on in my experience with PostgreSQL is how transactions and locks can be used together to provide serializable logic.
Enhance the Stream API to support custom intermediate operations. This will allow stream pipelines to transform data in ways that are not easily achievable with the existing built-in intermediate operations. This is a preview API .
Slow, unreliable CI/CD? Learn how to use SLOs, SLIs, and Error Budgets to maintain focus, prioritize effort, and rebuild developer trust in CI/CD.
If you enjoy this article, I have published a book explaining the internals of Git through implementation: Building Git .
