Elixir Livebook is my tool of choice for Advent of Code. The language is well-suited for the puzzles, I can write some Markdown if I need to record some algebra or my thought proce…

See https://github.com/KeithFrost/KeithFrost.github.io/blob/main... for the source code. This is a javascript version of the code from https://github.com/KeithFrost/frac5 described…

I used Numerical Elixir to make a generate a new type of colorful fractal images.

This is a very sensible confusion. The forms of macroscopic averaging functions which are useful and valid cannot be made up arbitrarily, but are determined by the microscopic phys…

> Quantum fields make non-negligible contributions to the gravitational source in these models. That means that, for a fully consistent model, you need a theory of quantum gravity,…

That should read as 60^2 - 1^2 -- the twos should be typeset as superscript.

Yes. I'm surprised the author would be more concerned about confusion between U/V (or u/v) than between 1/l ... the former has always seemed relatively far-fetched to me, whereas d…

I have only one complaint about this Base32 encoding choice, and it stems from the fact that I prefer to encode Base32 using lower case letters, instead of the choice made here to …

This is an excellent, and puzzling, question! Let me try to provide some insight into how physicists think about such paradoxes, by addressing the specific example you mention, of …

The English idiom is precisely "throwing out the baby with the bath water." So, as they say, you "hit the nail on the head."

This is clearly not true. If it were an effective means of getting accurate information, then there would be moral arguments for using it in some situations, to prevent even worse …

here here! okay, i'm going to reign this in.

Clojure allows one to start with essentially untyped code, then add type declarations for efficiency and safety.

That pocket looks rather like an anomaly in the data. There is a very large coal-fired power plant (Navajo Generating Station) near Page, Arizona, though.

One caveat regarding "Always put each migration into a database transaction": I've found that for very large database tables on a live system, it becomes impractical to e.g. create…

agreed, except that in the last sentence you mean "transparent" not "opaque" (the atmosphere must be relatively transparent at a particular wavelength to allow radiant energy to es…

No, I don't think so. Archimedes' principle tells us that the decrease in force required to support the object is equal to the weight of the displaced liquid. The force of gravity …

Amazon certainly has its share of problems and failures, but a lack of strategic financial thinking is not one of them. Take a look at the graph [1] of Amazon revenue and profit ov…

Much simpler calendar has 364 = 13 * 28 days. 13 months of 28 days (EXACTLY 4 weeks) each. This one is so simple, it might be worth having 1-2 extra-calendar days per year, even wi…

One tool for this is the 'comm' utility: given two files containing sorted lines, it can output one or more of (1) lines only in file 1, (2) lines only in file 2, and (3) lines com…

On the other hand, using a 64 bit integer to count seconds moves the problem 292 billion years forward, and we can probably let the Omega Point handle it from there.

Note that Amazon is not on your list. They did not adopt the mono-repo approach. Their tools have their own advantages and disadvantages, to be sure, but mono-repo is not the only …
