I'm sure most of us have had to deal with issues reported by end users that we ourselves aren't able to reproduce

This video is an extended case study going through my thought process as I tried to track down and fix a mysterious performance regression which impacted a small subset of end users

I look at the impact of acquiring mutex locks across different threads, identifying hot paths by attaching to running processes, using state snapshot comparisons to avoid triggering hot paths unnecessarily, the memory implications of bounded vs unbounded channels, and much more

After learning how to add an unstable overlay to nixpkgs, being able to override individual service modules from unstable was something that I still struggled with until fairly recently. Hopefully this helps someone else looking to do common-but-not-very-obvious operation.

Apologies in advance for sharing two link posts here two days in a row. Unemployment may be driving me a little nuts... 😅

I've been working on Satounki since I got laid off last month. It's the culmination of a lot of experience building similar ad-hoc internal tooling at various places throughout my professional career.

Satounki already includes:

• AWS support
• GCP support
• Cloudflare support
• Auto-generated Terraform providers from the Rust API
• Auto-generated Typescript client wrapper from the Rust API
• Slack bot for request notifications, approvals and rejections
• CLI for requests, approvals and rejections
• Dashboard for exploring policies, requests and stats

The scope of this project is pretty big and I'm looking for contributors.

The majority of the project is written in Rust, including the generated Go and TS code. The stack is pretty simple; Actix, Diesel, SQLite, Tera etc., so if you have experience with writing web apps in Rust it should feel familiar!

Even if this is a totally new stack to you, this is a great project to develop some familiarity and experience with it, especially if you can help improve the quality of the generated Go and TS code at the same time!

Found some time this past weekend to work on a little "passion feature" that I've been wanting to implement for a while now; sharing the technical write-up for anyone else who is interested in automating headless screenshots with these tools or with others (the knowledge is pretty transferable!)

I re-watch this powerful short "illustration on addiction" every year to remind myself of the importance of waking up and choosing sobriety every day.
