Do you think it is attainable ? Could someone like you break the task up into small enough pieces to let each piece be coded by a group of rust newbies ?

This paper is written by three Europeans who clearly understand these mathematical ideas.

whitten··on A colorful Game of Life
Apparently not. I read that it is using an averaging rule for cells around a cell to see if it is alive for the next generation

The code is here: https://colorlife.quick.jaredforsyth.com/index.js The hue of each cell is computed as an average of the surrounding cells hues with some randomness added. Search for `hueverage` in the code reply

whitten··on The APL Challenge
Has anyone tried to recreate LLMs in APL ? Matrix multiplication is common in both of them. If LLAMA.C is only a few hundred lines then I would be surprised if the APL is more than a page of code.

whitten··on Software Folklore
As the old cartoon said: the repairman charged $5000 to come fix a machine. When he showed up with a hammer, walked up to the machine and gave it a whallop with a hammer and it immediately started working.

The bossman asked for an invoice which he wrote up on the spot.

It consisted of two lines:

1) tapping the machine $5

2) knowing where to tap: $4995

whitten··on Software Folklore
I’m trying to track down an old story about the network not working in a firm on Wednesday morning near 7 am.

I remember the details being that only on Wednesday did they use the freight elevator to deliver donuts to an all-staff meeting and when they did, the network would fritz.

It turned out that if you move a very large electromagnet (on the elevator) along the network cable, it makes the network go crazy.

Combine that with cable-pullers that rather than putting holes in multiple ceilings and floors in the cable closet, saw that the elevator shaft was a pre-existing hole between floors anyway, simply took the path of least resistance and hilarity (and a real hard network debugging problem) ensues.

Does anyone know when or where this anecdote occurred ?

whitten··on Show HN: Ternary Computer System
Do you use the idea of the previous post to store 5 ternary digits in one eight bit byte ?

whitten··on Wirth's Law
Is it possible that there are different kinds of software, so the Wirth’s law of software slowing down to negate the speed up of hardware due to Moore’s Law only works for some kinds of software ?
whitten··on Ardour 8.8 Released
I think Ardour is a tool for sound manipulation. Possibly only for MIDI format sound files.

whitten··on From Plato to Pixels
I remember a design book that emphasized that the best designs are those left after you remove all the distractions and cruft from the current design.

Crazily, I remember Joel on Software saying the best programs are full of cruft, ie all the inelegant details that make it work with all the various environments which can make it deal with the imperfections of the real world, so that using it is as smooth as possible and not revealing all those places which making using it so difficult.

whitten··on GLP-1 therapy increases visceral adipose tissue metabolic activity
So basically some drugs encourage the metabolism of people who need a CPAP to lose weight, possibly tied to brown adipose tissue.

It works in mice and probably works in humans but was not the main focus of the study so they didn't have a good control group to be able to prove it.
