The DCT is a cool primitive. By extracting the low frequency coefficients, you can get a compact blurry representation of an image. This is used by preload thumbnail algorithms like blurhash and thumbhash. It's also used by some image watermarking techniques to target changes to a detail level that will be less affected by scaling or re-encoding.

I made a notebook a few years back which lets you play with / filter the DCT coefficients of an image: https://observablehq.com/d/167d8f3368a6d602

Nature recently posted an interesting video [1] about what causes developing hearts to have their first beat. The gist is that eventually random electrical noise triggers a propagating wave which is then continued and repeated by the cellular automation nature of heart tissue. You don't need as much software if your system is composed of emergent properties.

Ton is a personal hero of mine. When I was a kid, I wanted to be a 3d animator because of Ton. I discovered Blender in the early 2000s as a kid. It was my first exposure to digital art tools because it was free. When Blender open sourced in 2002 it was a massive gift to kids around the world like me. (Ton was kind enough to reply to an email of mine at the time thanking him!)

Ton and Blender have brought so much value to the world by making world-class creation tools available to everyone. Blender is one of the most successful open source projects of all time -- going from an underdog project notorious for difficult to use UI to a polished, ubiquitous, industry shaping tool. And never losing sight of the art; it still brings a huge smile to my face when Blender ships another Open Movie. Nearly ~25 years later, thank you again Ton.

For users with SSDs, saving the write wear seems like a desirable default.

In my experience these are after exposures from lines of text. They get blurred together into indistinct lines because your eye focus moves between words, superimposing them.

I replicate my entire filesystem to a local NAS every 10 minutes using zrepl. This has already saved my bacon once when a WD_BLACK SN850 suddenly died on me [1]. It's also recovered code from some classic git blunders. It shouldn't be possible any more to lose data to user error or single device failure. We have the technology.

Selkies[1] is another interesting project in this space. It uses webrtc for low latency streaming and remote desktop suitable for gaming in the browser.

Sounds like a good time to engage a professional coach or therapist, if you haven't already. Particularly to deep dive on the questions asked at the end of the post. In my experience, I often stalemate these kinds of internal debates on my own, but having a second player in the mix got me out of the gridlock.

Migrating out of this mess caused me downtime.

Squarespace's domain panel crashed with a nondescript error when I tried to update nameservers prior to transferring out, and they shut off the Google nameservers as soon as the transfer went through on their side. To add insult to injury, Squarespace makes you wait 5 days for a transfer, with no way to expedite -- and in my case, they waited 6 days, taking me offline on a Friday night. This was the worst experience I've ever had using a domain service.

My favorite part:

If you develop a new program, and you want it to be of the 100% possible use to the public, the best way to achieve this 100% is to make it 1000% free software which everyone can redistribute and 100% change under 100% these terms.

Keybase always performed crypto on-device using their open source client written in Go. What not-your-keys not-your-crypto setup are you referring to?

Alternatively for the case of id strings with known prefixes, a unique feature of TypeScript is you can use template string literal types:
