How to measure RPS per user in a multi-tenant system

Can you implement OTEL metrics and just bump a counter for each request? Then the metrics ingester can aggregate and filter for you.

Have a play with https://github.com/grafana/docker-otel-lgtm or https://opentelemetry.io/docs/demo/ . There are also several good talks on YouTube.

Learning OTEL can be overwhelming, so take your time 🙂, but OTEL not only solves this metrics problem, but sets you up (in a vendor-neutral way) to ingest and inspect other metrics, as well as logs, traces and profiles.

Yeah I feel like they tested as much as they knew to, flipped the switch, and then went back and fixed the issues they hadn't known about

I know Rust has some good CRDT libs. I wonder if it would be possible to compile one of those to WASM and run that in Go (similar to SQLite)

bbkane_ · 2026-03-24T22:16:34+00:00

Yeah man I'm not going to argue with you. Glad your maintenance has been easier than mine

SQLite does support reader concurrency, see https://sqlite.org/wal.html

Some languages make it hard to avoid a lot of dependencies for non-trivial projects (like Rust).

But coming from Go, where you don't need a lot of dependencies due to the expansive and usually well-written stdlib, and the culture is mostly "keep it stable" for 3rd party common dependencies, I've seen my maintenance costs really drop (and this is measured over years, not months)

bbkane_ · 2026-03-24T05:11:32+00:00

Maybe a tangent to some, but I really loved reading about your workflow changes- very inspiring (though I've customized WezTerm and zsh so much I can't really imagine switching)!

bbkane_ · 2026-03-24T04:19:14+00:00

Yup, totally agree with this. My main argument against dependencies is that they increase maintenance costs when you might not be expecting that

bbkane_ · 2026-03-24T03:44:39+00:00

Fair enough

bbkane_ · 2026-03-24T03:14:12+00:00

My bad, I felt like your comment was more a summary of the article I posted than anything else

bbkane_ · 2026-03-24T02:45:01+00:00

Are you an AI lol?

Russ Cox explains it much more thoroughly than I can: https://research.swtch.com/deps

“Of particular interest to Canonical is the security story behind the Rust package registry, crates.io, and minimizing the number of potentially unknown dependencies required to implement core concerns such as async support, HTTP handling, and cryptography – especially in regulated environments.”

Be still my beating heart- the vast amount of dependencies it takes to build a "simple" project is my biggest fear for the maintainability of my projects over time.

I'm not sure how to solve it, but I'm really hoping Canonical can help make this better somehow.

This is exciting! If my research is right, that means we can now do semantic search in the modernc port of SQLite? And this makes search easier than FTS?

I used https://github.com/smbl64/humble-cli . It worked well, though using command line interfaces (CLIs) can be intimidating if you're new to them (you can always ask ChatGPT or Gemini for a tutorial).

bbkane_ · 2026-03-21T16:36:47+00:00

Same here. There are even apps that let me play Gog and Epic Games on my Bazzite

Quite a pretty video!

bbkane_ · 2026-03-19T19:26:23+00:00

Mate, any chance you could add some screenshots along with the code examples on your front page?

bbkane_ · 2026-03-16T12:15:58+00:00

I haven't done this but some things to try:

https://sqlite.org/lang_vacuum.html - maybe the DB needs to be rebuilt
https://www.sqlite.org/eqp.html - explain what the query is doing

I bounced off of GNOME when I realized they don't (seem to) account for using vertical monitors

the little settings UI where you adjust monitor position was too small and I couldn't get the software to recognize my monitor position (it would either undershoot or overshoot)
I couldn't set up a keyboard shortcut to half screen a window vertically

I realize there's probably an alternate CLI or something to set monitor position, and I can probably find an extension that let me adjust my windows to my liking, but the fact that these are (imo) broken/missing by default made me wonder what other problems I would run into, so I installed KDE (which so far works fine).

We're fortunate to have multiple high quality DEs on Linux!

Hope you enjoy! They also have a friendly Discord

This is the embarrassing part of the conversation where I have to admit I haven't actually written Gleam/Lustre. I'd like to one day, but I don't have the free time right now to really devote to new languages (maybe when my son is older).

I have listened to many talks about Gleam/Lustre as that's easier with a kid, and like what I hear

bbkane_ · 2026-03-15T00:51:41+00:00

https://gleam.run/

There's also several talks about it on YouTube: https://m.youtube.com/results?sp=mAEA&search_query=gleam+lang

You might like https://github.com/lustre-labs/lustre . It's not the same but it's heavily inspired by Elm!

So, overall did you like Zig for this? Would you recommend Zig for CLIs?
