I present a Rust-specific sequel to my previous benchmark of 2 Kotlin and a Rust microservice — it’s hard to resist one’s own curiosity and popular demand, especially when you’ve been nerd-sniped. Let’s stress-test the two prominent web frameworks: Actix Web and Rocket. In addition to stable “threads & blocking calls” Rocket v0.4, I have included a development snapshot of in-the-works Rocket v0.5, which is async and no longer requires nightly Rust.Read more

Back in spring 2020 at GoOut, we were looking to replace our Spring-Tomcat duo by a more lightweight framework to power our future Kotlin microservices. We did some detailed (at times philosophical) theoretical comparisons that I much enjoyed, but these cannot substitute a hands-on experience. We decided to implement proof-of-concept microservices using the most viable frameworks, stressing them in a benchmark along the way. While Kotlin was the main language, I saw this as an opportunity to have some fun at home and test (my proficiency with) Rust, which is touted for being fast. I ended up stress-testing Kotlin’s Http4k, Ktor, and Rust’s Actix Web, read on to see how they fared.Read more

Do you frequently SSH into Google Compute Engine VMs using gcloud compute ssh ... and own a physical OpenPGP-compatible SmartCard/USB key? This post, also serving as a future note to myself, shows how to use these together for fun and profit convenience and security.Read more

Heya folk,
I need your help. Amarok has been able to sync personal metadata like play count, rating, labels with your library on Last.fm since version 2.7. Unfortunately one of the most valuable piece of information, last played time (and also first played time) still cannot be synced due to minor omission in Last.fm Web Service API.Read more

Ahoy, it is the time of the year again. The Google Summer of Code has just ended and here I come with the final report, joining my fellow Amarok GSoC student Konrad Zemek with his excellent posting.Read more
