So like Testcontainers Cloud?

oweileron The 1987 game “The Last Ninja” was 40 kilobytes

oweileron Chibi Izumi: Phased dependency injection for TypeScript

It just gets rid of the boilerplate. Never had a problem with ctor injection in Spring.

oweileron Result is all I need

Use the builtin Result class and runCatching/fold and be done with it. Yes, it has shortcomings but works well enough in practice.

oweileron Page Object (2013)

This is honestly the main reason I prefer Playwright to Cypress. Playwright leans heavily into using POs, while for some reason Cypress doesn't.

So in almost every project the Cypress tests are a procedural mess, while the Playwright tests are mostly well structured.

I know that Cypress has other patterns for dealing with this but they never seem to get applied.

oweileron Starship: The minimal, fast, and customizable prompt for any shell

I use Starship without any customizations and its good enough for my every day use.

oweileron DropZap World – My falling block game with lasers, released after years of work

Reminds me of a game I've played on C64 AS a kid.

Bash has no standard library. It has builtins, and commands. And commands are just external tools.

I have read almost the same thing 5yrs ago. And 5yrs before that. And so on.

Yet. It's a drop-in replacement, and both faster and cheaper.

oweileron Pinball Brothers – A Swedish-Italian Pinball Company

Can such a company actually be profitable? The market seems tiny.

oweileron Magnesium Self-Experiments

Performance is one problem, but much worse are the countless bugs which plague the last releases.

oweileron Shell-ish scripting in Go with ease

Did you do thorough error handling in Bash?

oweileron How rqlite is tested

That's why I prefer test frameworks that make parametrised tests so easy that they become the default.

Kotest and Spock are such frameworks.

oweileron Distributed Transactions at Scale in Amazon DynamoDB (2023)

Aurora Serverless Postgres e.g.

oweileron Today I learned that bash has hashmaps (2024)

They are also slow AF because a lookup takes linear time.

oweileron Be Aware of the Makefile Effect

That's why suggestions like RTFM! are stupid. I just don't have time to read every reference documentation of every tool I use.

oweileron Java in the Small

Kotlin is much better in that regard.

I use Kotlin scripts (.main.kts) as a replacement for Bash scripts for years.

You can inline dependencies without additional tooling, and Kotlin is still much more expressive than Java.

oweileron Advent of Code 2024

I will probably solve the first 7 puzzles like every year and then just stop.

oweileron PicoCLI – Powerful command-line parsing library for Java

Great library for scripting, especially in combination with GraalVM and JBang!
