We take our trust in our users seriously. This is why existing apps are supported until August 31st, 2027 (1 year, 10 days away). Backups will stay available until August 31st, 2028 (2 years). The product is full open source, and we put a lot of work in making it easy to self-host.

This is an exciting project! My main feedback: you can definitely tell the website content is AI-generated. It's okay to vibe code the design, but I really hesitate when I see vibed writing.

Nice! Would love a brief explanation of the infrastructure. I see the Powered by "Upstash Redish Search", but why choose Upstash Redis Search vs something else?

Show HN: Baserates.dev, memorize programmer napkin math

stopachka — Mon, 22 Jun 2026 00:50:48 +0000

When I began my career in programming I remember reading Jeff Dean's "Latency Numbers Every Programmer Should Know" [1], and getting inspired. Alas, it's been over a decade, and I never fully internalized all the numbers.

Until recently. I discovered Simon Eskildsen's talk [2] and github repo [3] on programmer napkin math. I liked his reasoning, and decided to _actually_ internalize the numbers now.

So I made baserates.dev.

It's a spaced repetition program that teaches you the napkin math from Simon, enhanced with a few things from Jeff Dean's list. The main changes: I included CPU instructions, like L1 Cache reads. I also included some nooby context, like how to pronounce the character μ, and a reminder on what is bigger: nano seconds, or micro seconds.

The app automatically saves your progress, and doesn't require auth. Most of the logic is vibe coded: I fed Claude all the links. I use InstantDB [^4] for the backend, mainly to support guest auth and saving progress. Most of my time spent on the project was just going through and making sure the numbers were right. [^5]

Hope you enjoy it!

New comment by stopachka in "Building agents without harness engineering"

stopachka — Thu, 11 Jun 2026 20:38:43 +0000

Interesting idea! Question:

> It is highly unlikely that an AI agent startup becomes wealthy by creating the best harness for a particular use case.

If it's not the harness, what do you think is the thing that will differentiate AI agent startups? Is it mainly data, or something else?

It’s interesting that Claude chose to hint, rather than reveal the full truth or to lie.

I wonder what in the training / system prompt causes Claude to do this.

I don't quite understand, what would 100K buy you?

AFAIK you would get about ~5 concurrent users, with a max context window of ~128K tokens on the larger models.

This wouldn't be good enough for coding -- are you guys thinking of using it for something else?

Instant gives you a database, but it also gives you a sync engine that you can use in the frontend. We included this instruction because you would ideally use this to build an app.

Currently we recommend folks to write a script with the admin sdk. Efficient import / export is on the roadmap!
