Thank you. We have not really started advertising, but my wife is (very) often complimented on the jewelry when she wears it and that has led to a few sales.

Thanks. Good idea. What I often ended up doing is asking it to draw 3 labeled arrows X,Y,Z. So I could tell it to orient along the XY labeled arrows (which are in reality YZ, but w…

Built a tool to help design cs/science inspired jewelry in CAD. I wrote a DSL to describe the jewelry, and had an LLM write the interpreter to generate a CAD file using cadquery (n…

If I remember correctly, in that book Galileo says he heard of someone in the Netherlands having made a microscope, but without any details about how it was made. Armed with the kn…

Galileo refers in this to a book he had published earlier, the "Starry Messenger". It is well worth reading. Galileo had just build the first ever telescope and he describes what h…

Fun fact: if your first name is Isabella you can visit the museum for free. I believe that she specified this in her will.

If you like Bach you might want to learn to listen to polyphony: the form of music in which multiple melodies are played simultaneously while forming an harmonious whole. I recomme…

I was using sed to do many replacements (hundreds) in a file and it was starting to be slow, running in O(num_replacemnts). I thought that this can be done with a state machine so …

Not the author, but I had a similar problem. If you specify many replacement rules in sed, it will run in O(num_replacements * num_lines). You should be able to use a state machine…

If I remember correctly, the system calls where indirect jumps where the address of the jump was in ram (it had been copied from the rom on startup): it was designed to you could h…

I have heard that it is good practice to always chose the number of teeth of two gears to be relatively prime. This is because there can be impurities in the metal, and if you have…

In some/many cases there is code before the branch that does not influence the branch condition. In that case, would it be possible to architect the cpu such that it could execute …

Would it be possible to do a special distribution for non emacs users? I'm thinking of one download with emacs + magit + CUA mode by default + run magit-status on startup (or whate…

Slightly off-topic question about WaveNet: In the paper, they say that they double the dilation factor up to a limit and then repeat: 1, 2, 4, ..., 512, 1, 2, 4, ..., 512, 1, 2, 4,…

I also like the concept of "engine-rich exhaust" (also known as "the engine is melting").

A different solution to the Box in box problem, with less math: Consider the square of (length + with + height). The sum of the diagonal terms is the square of the distance between…

Using the same brushes as Leonardo da Vinci will not make you a better painter.
