In this lightning talk, I show age-plugin-se in action, and touch on the steps taken to make it robust, simple, and distributable on multiple platforms (including Alpine Linux), all while keeping the dependencies (including tools) to a minimum.
While trying to build my Age Apple Secure Enclave plugin , a small Swift CLI app, on Alpine Linux , I realized that the Swift toolchain doesn’t run on Alpine Linux. The upcoming Swift 6 will support (cross-)compilation to a static (musl-based) Linux target, but I suspect an Alpine Linux version of Swift itself isn’t going to land soon. So, I explored some alternatives for getting my…
The age plugin for Apple’s Secure Enclave is a small, platform-independent Swift CLI app, built using the Swift Package Manager . Because it does not use Xcode for building, you can’t use the Xcode IDE for collecting and browsing test coverage of your source files. I therefore wrote a small (self-contained, dependencyless, cross-platform) Swift script to transform SwiftPM’s raw…
While watching a Strange Loop talk on concatenative programming , I learned about Uxn , a small virtual machine that runs games, editors, drawing programs, … Uxn has been ported to various platforms , including classic consoles such as the Nintendo DS, GBA, Playdate, … There also is a JavaScript version: Uxn5 . Since the Uxn5 core was a straight translation of the C reference…
In this post, I’ll walk through a small example of a Go web app for Cloud Run that uses Go 1.21’s standard library slog package for structured logging to Cloud Logging. Contrary to the documented ‘standard’ approach for logging , this example doesn’t use any third-party logging package for logging. Instead, it relies on Cloud Run’s support for ingesting…
For my day-to-day encryption needs, I’m a big fan of age . age is a simple, modern and secure file encryption tool, and serves as a better replacement for tools such as GnuPG. You can even use it as the backend for managing your passwords . For extra convenience and security, I wanted to be able to use my MacBook’s Secure Enclave (controlled by Touch ID) to encrypt files, so I created…
In this FOSDEM'23 talk, I dive into the details of WAForth, a tiny but complete Forth interpreter and dynamic compiler for and written in WebAssembly.
In yet another ‘probably-useless-but-interesting’ hobby project, I wrote a Forth compiler and interpreter targeting WebAssembly. It’s written entirely in WebAssembly , and comes with a compiler that dynamically emits WebAssembly code on the fly. The entire system (including 80% of all core words) fits into a 10k (5k gzipped) WebAssembly module. You can try out the WAForth…
One of the first things that impressed me about Mac OS X when I first saw it was its screensaver. Instead of just showing a simple slideshow of your pictures, it actually used a Ken Burns panning and zooming effect with a fancy fading transition to make the otherwise static pictures really come to life. It always sounded like a fun project to create a standalone tool to create slideshow movies…
React ’s standard flow is to start with an empty HTML template from the server, and populate the DOM entirely on the client. Letting React pre-render the initial HTML for your app on the server before the client takes over has some advantages, though: it lets slower (mobile) clients load your app much faster, and it’s good for SEO for search engines that don’t support JavaScript.…
