skreem··on PGSimCity - How PostgreSQL Works
This is really cool, I like having visualization to hold on my head!

Also (assuming this is LLM-generated, apologies if it’s not) seems like the future of learning/self-teaching… gonna try and generate similar things for stuff I’m learning

skreem··on Ask HN: What Are You Working On? (July 2026)
Oh interesting… I don’t manage it, but one of our teams does fully self host it

Have you tried setting CODER_ACCESS_URL to your own hostnamE/IP? I think that disables the tunnel setup

Very cool, it’s insane to me how frustrating the S3 UI is. My current annoyance is bulk downloading is hard, and seeing things like “how large is this bucket or specific key prefix in bytes”

Saw you using DuckDB at internal/handlers/api.go

Wondering if you’d considered letting queries operate at the bucket or key prefix level instead of requiring key to specific file? Or is that already supported?

I’ve liked being able to point DuckDB to a folder following Hive partition scheme, and then querying it just like Spark/Trino would over many files

Oh this is awesome, will take a look. I’ve had rough experiences with Kubeflow in the past, recently I’ve been using Coder workspaces https://coder.com/ and it’s pretty good but less ML/AI integrated (but, stitched together with Ray autoscaling nodes it can get really nice)

I’m working on https://urhired.ai

It’s an AI-powered mock technical interviewing platform, for system design and coding.

I’m also working now on behavioral mocks, with a coach feature!

I’ve been working on it on and off for a year, but started spending significant time in the last few months.

I know everyone’s burnt out on LLM products, but I think it’s nice for this kind of prep since you can do it on demand and in an environment it’s safe to fail as much as you need without judgement so you can actually learn.

It’s early and free if anyone is interested in trying it out (at least while I can afford to serve it for free)

skreem··on Prefer duplication over the wrong abstraction (2016)
Nice to see Sandi mentioned! If anyone liked her philosophy / writing style I highly recommend you check out her books

I read “Practical Object-Oriented Design (POODR)” ages ago at this point, but it reshaped how I approached OOP

Granted… OOP as a default paradigm has fallen out of favor (at least for me), but it’s still everywhere & won’t be going away. She gives a great framework for making it sane

skreem··on Bab: A hash function for content-addressable storage
This is pretty interesting, I’m wondering if any major CAS-based projects have adopted it over BLAKE3 (which has Cargo & Bazel usage)?

Also would love to see performance benchmarks against other hashing algos
