I use Emacs for programming but when working with Git, Pass, crontab or other UNIX programs that utilize EDITOR env var I'm in Ed which works very well for small edits. So I'm not using Ed for writing code but I use it daily for things like Git. My full story: portal.mozz.us/gemini/tilde...

well that's my content schedule sorted right there. thank you mr ai 👍
a series of bizarre ai generated video ideas: "Visualizing mathematical beauty in seminumerical algorithms through interactive real time...", "building a hardware processor designed specifically for knuth's mix machine instructions", "applying combinatorial search strategies to solve complex modern supply chain logistics", "designing my split screen workflow for maximum deep work and focus", "the mystery of identity and strategy behind launching a second youtube channel", "reimplementing knuth's fundamental algorithms using modern memory safe rust"

[Illustration of a man wearing glasses with a little camera strapped to his forehead and a square drawn around his pupil]. A scientist of the future records experiments with a tiny camera, fitted with universal-focus lens, the small square in the eyeclass at the left sights the object.

AS WE MAY THINK

A top U. S. scientist foresees a possible future world in which man-made machines will start to think.

A screencap from a book which reads: Figure 4.5: Not quite right. Then a grid of 9 dots with lines joining them up. Then a section that says Tip: Use whole-brain thinking.

Ed is the standard unix text editor. It's also strange. This is a video about ed, why it is the way it is, and an alternative vision of computing in the world that may just be coming back. youtu.be/GoyNMFccbow

can't believe i missed this vintage shot of 80s Alfred Aho for the last video... would have been so perfect!
80s photo of Alfred Aho in his very... teal? office space, wearing a blue jumper under which shows the broad collar of a white shirt, in front of a million papers and a huge yellow computer terminal

Wikipedia says that comp sci professor Rao Kosaraju originated the saying "At some point, the learning stops and the pain begins." — what do you think it means?

every day i get up, i make another clone of ed the Standard Unix Text Editor, i do my burpees, and then i study Unix v7's ed.c to figure out how on earth it works. feels like leetcode for trying to get a job at Bell Labs in 1975

new video! there is actually no way to describe this topic in a way that sounds interesting so i'll just say it's about whether 1.5 or 2 is friendlier youtu.be/GZPqDvG615k

new video! this datatype → [1, 2, 3] ← is a bit of a marvel. it can store items of any size, grow to any length, rarely causes performance issues, and almost every modern language has one. what is it, really? and how does it work?

Hi all! For flu-related reasons I didn't stream/post so much thru AoC this year, so I made this post to write up a few things I'd meant to put in a video at some point about what I learned open.substack.com/pub/klog/p/3...

Enjoying puzzles, some rough notes on solving, and streaming.
