Notes from notnotp.com

I got tired of using onetimesecret.com so I built my own secret sharing service.

Due to shortages, RAM is very expensive right now.

Almost a year ago I switched from my good Linux Ryzen 7 PRO-based ThinkPad to a MacBook Air M4.

Whan I started this blog, I wrote an "AI disclaimer".

So I've been job hunting lately.

The Internet is almost anonymous and privacy-preserving by design.

I needed to call an RPC service hosted behind a home NAT, with no public IP and no port forwarding.

This article shows how I implemented semantic search in SQLite using binary embeddings and Hamming distance, enabling hybrid search without external vector databases.

Here are the technical books I plan to read this year.

Last week, AWS launched its European Sovereign Cloud, a physically separate infrastructure ("partition"), operated by EU residents, under a German legal entity.

LavaRand implemented by Clodflare uses lava lamps to generate random numbers for cryptography, but the camera sensor capturing the images already produces abundant entropy from unavoidable physical noise.

It turns out the recent Arduino models such as the ARM-based UNO R4 can act as USB-attached HID devices.

ARM has this very specific instruction, FJCVTZS, doing "Floating-point Javascript Convert to Signed fixed-point, rounding toward Zero".

Ten years ago or so, I self-hosted everything: file storage, calendars, DNS, analytics, version control.

900k users got their AI conversations stolen by malicious Chrome extensions, according to this article.

I needed to monitor a few servers: this website, and some APIs I run for my small company.

Every time IDs are discussed on Hacker News, someone suggests encrypting them instead of using public-facing UUIDv7 or other alternatives.

I wanted to move away from Node.js and the practices that come with it.

Last fall, I started learning Go seriously.
