I need to deslug my computer, it's getting sluggish.
hcs··on Forty-Four Esolangs: The Art of Esoteric Code
The author's Olympus language is amusing, programs are expressed as prayers to ancient Greek gods. https://danieltemkin.com/Esolangs/Olympus/

It reminded me of an overambitious educational game idea: The player builds interpreters for prayers directed at several gods, each cult having its own theurgic practices resembling different programming paradigms: https://gashlin.net/blog/pages/2010-12-25-shell-script-of-th...

hcs··on A Technical Update on Submarine Cables [pdf]
I think it's mostly that the fiber isn't a perfectly transparent medium, over tens of kilometers attenuation adds up. As said in https://news.ycombinator.com/item?id=45159639 these are just to boost power, they don't reform the signal.
hcs··on Anthropic agrees to pay $1.5B to settle lawsuit with book authors
If I'm reading this right yes the training was fair use, but I was responding (unclearly) to the claim that the pirated books weren't used to train commercially released LLMs. The judge complained that it wasn't clear what was actually used, from the June order https://fingfx.thomsonreuters.com/gfx/legaldocs/jnvwbgqlzpw/... [pdf]:

> Notably, in its motion, Anthropic argues that pirating initial copies of Authors’ books and millions of other books was justified because all those copies were at least reasonably necessary for training LLMs — and yet Anthropic has resisted putting into the record what copies or even sets of copies were in fact used for training LLMs.

> We know that Anthropic has more information about what it in fact copied for training LLMs (or not). Anthropic earlier produced a spreadsheet that showed the composition of various data mixes used for training various LLMs — yet it clawed back that spreadsheet in April. A discovery dispute regarding that spreadsheet remains pending.

hcs··on Anthropic agrees to pay $1.5B to settle lawsuit with book authors
The lawsuit didn't find anything, Anthropic claimed this as part of the settlement. Companies settle without admission of wrongdoing all the time, to the extent that it can be bargained for.

Compression + encryption can be dangerous if the compression rate is exposed somehow (between messages or within packets of a message).

hcs··on AI adoption linked to 13% decline in jobs for young U.S. workers: study
> "What's actually happening" is all your life you've been told that human intelligence is magical and special and unique. And now it turns out that it isn't. Cue the coping.

People have been arguing this is not the case for at least hundreds of years.

This is an especially bad example, a nice shiny grille is going to be strongly reflecting stuff that isn't already part of the image (and likely isn't covered well by adjacent pixels due the angle doubling of reflection).
hcs··on The Open-Office Trap (2014)
Anecdotes:

I had what seemed to me a standard office, door but no window, in 2008 at my first job out of school at IBM in Austin. Some folks in that same hallway were doubled up but I was lucky to have one to myself while there.

A few jobs later in 2011 I also had one with a door, wall was a half-frosted window onto the hallway, was doubled up with another new hire eventually, this in SoCal, Ventura County.

Then in grad school from 2012 in NYC, also had a closet-scale office I shared with one of a rotating cast of officemates, that had an exterior window, nice view of 1 WTC as it was going up.

Since then (2016 on) it's been open offices, but at least with individual (if joined) desks, then WFH.

hcs··on A Global Look at Teletext
When I was recently researching Japanese videotex systems for similarities to CD Graphics, I ran across Captain https://en.wikipedia.org/wiki/Captain_(videotex)

It was somewhat unique in that (at least originally) it only transmitted bitmap graphics, rather than having a hybrid system with some characters in ROM and others dynamically loaded.

hcs··on Consider using Zstandard and/or LZ4 instead of Deflate
So someone is going to load 2.5x as many images because it can be decoded 2.5x faster? The paradox isn't a law of physics, it's an interesting observation about markets. (If this was a joke it was too subtle for me)

> The Beginners Guide even worse. Empty test levels strung together with tedious narration.

> The developer's depressed? That's the least interesting thing to learn about anyone. Depressed people promoting their depression sounds disingenuous.

I wonder if you played The Beginner's Guide to the end? Not that it necessarily would have changed your mind, maybe the conclusion didn't strike you as it did me (even seeing it coming).

hcs··on The Vectrex Computer
I recall reading that the design kicked off because of some stock of surplus CRTs but that didn't ultimately end up used.

https://www.gamedeveloper.com/design/a-history-of-gaming-pla...

> The system got its start in late 1980, when one of the hardware designers at Western Technologies (Smith Engineering), John Ross, had a light bulb go off -- or, to be more precise, a surplus one-inch Cathode Ray Tube (CRT).

> Western Technologies redesigned the system as a tabletop, and later that year General Consumer Electronics (GCE) licensed it for production -- though now with a nine-inch screen.

> a str with invalid UTF-8 may cause UB, it's not unsafe to handle a str and they sure aren't going to put checks everywhere for it

Any way I know of for making a str from bytes is checked or unsafe, even slices (by byte indexes) are checked (panic). Is there a current example that hasn't been fixed at the language level where this invariant can be broken without unsafe?

hcs··on Richard Feynman's blackboard at the time of his death (1988)
> "What I cannot teach, I do not understand"

I tend to agree, but teaching another person is also a whole different set of skills from being able to drive something yourself.

One prominent example is the "curse of knowledge"; it may take a lot of practice becoming a beginner to be able to teach for a beginner's perspective in your area of expertise.

hcs··on Undergraduate shows that searches within hash tables can be much faster
Proofs of constant time operations include time taken to resize the table. This takes much more time (linear in the size of the table), on insertions when the table is resized, but that time is amortized over all the insertions already done. It still works out to constant average time if you grow the table enough each time (once it starts to get too full) so it happens with decreasing frequency.
