> If you ask permission for spending, it's a very onerous and frustrating process. If you just deploy stuff and get billed for it, it's much easier! This point is underappreciated …

I’ve used Claude to help write development utilities to support my retro computing interests. The most complete tool being this unit testing support library for Apple IIgs assembly…

An interesting property of DAWGs is that the compact/compressed variation (CDAWG) can be built in linear time. https://moodle2.units.it/pluginfile.php/718375/mod_resource/...

I was halfway through the article and began thinking that his described data structure sounded very familiar to something I used about 20 years ago. Sure enough, the first paragrap…

An aside, but I recently learned -- if one is willing to use a very modest amount of memory -- summing floating-point numbers with no loss of precision is effectively a solved prob…

> Notice I have changed the extension from .js to .mjs. Don’t worry, either extension can be used. And you are going to run into issues with either choice As someone that has used …

I can see the point of trying to make a distinction, but it is muddy. An emulator can operate on many different levels of trying to match the behavior of the underlying hardware. C…

The states decided to add one digit to these numbers to further subdivide them. They did it differently, of course, and some didn't subdivide at all. Some of them have typos with "…

There are 8 screen hole bytes in the bottom 8 text rows (64 bytes total) and 8 expansions slots, so the screen hole byte at offset "N" was often used to store up to 8 bytes of data…

I thought that SmoothLife was fascinating when I found it. At the time I was doing a lot of simulation work, so methods for bridging discrete and continuous domains were interestin…

I just recently did a website conversion that used vite and took a look at both vitest and playwright. Ended up going with playwright for the “batteries included” browser support a…

Reminds me of Intellectual Venture's Optical Fence developed to track and kill mosquitoes with short laser pulses. As a side-effect of the precision needed to spatially locate the …

I was not aware of this (2015) work -- very nice! A couple of pull-quotes from the paper to summarize: Much work has been done on trying to improve the accuracy of summation. Some …

Surprisingly there are different algorithms for doing something as simple as summing up a list of numbers. The naïve way of adding numbers one-by-one in a loop is an obvious way, b…

Agreed, the differences aren't as stark as the map seems. Almost all of the states fall between 15% and 25% percent of the population. Wisconsin stands out at 25.29% of the populat…

This is giving strong "Using TDD to build a Sudoku solver" vibes[1]. Let's use some hot tools to solve a problem. Sorta solve a problem. Well, AI doesn't actually know abstract str…

> Also, I think some iPhone models have emergency satellite communications already, no? Yes, Emergency SOS. This was the feature that allowed a family to be located and rescued rec…

This guy just (like a few weeks ago) started to put together a decentralized newsgroup toolset based on the NNTP protocol. https://dialup.cafe/@vga256/110609250159276517

This is similar the the (old) trick of adding a Uniform distribution component to a Mixture of Gaussians model. It doesn't really change the math wrt parameter optimization and pro…

If SVB were originating mortgages then, yes, that should have helped because then, like every other originator, they would have immediately sold the mortgage into the secondary mar…

Esri’s Calcite Component library is another. https://github.com/Esri/calcite-components

That’s a great point. Seeing lots of mocks and assertions that certain functions are called is often much ado about nothing since no actual code functionality is exercised. I do so…

I think even more so than “If I can put things eloquently enough, perhaps they'll understand why I did what I did.", it can be motivated as “I don’t think I’m a bad person and I di…
