San Paco, Pax Calida Fornax

Noah's Notes

Mr. Croft, potato is not Latin for king of the peanut. It's actually from the Greek, pœtæΩ, which translates to God of all nuts. Your God; my God; the God of us all.




self description

I live in San Paco, a microstate off the left coast, under the protectorate of the Pax Calida Fornax.

I like science and art. I live with my cat, Wanda, and my daughter, Violet.

I was starting a new job once and I was asked for three words, qualities, that described myself. I wrote down "gumptious", "sagacious", and "pulchritudinous". None of these qualities were necessary for or utilized by my job.

wise, literally filled with or characterized by the qualities of a sage

Some Useful Unicode Symbols

In Linux you can enter Unicode hex values directly by holding ctrl and shift while typing u followed by the 4 digit hex value of Unicode character. You hold ctrl and shift for the entire sequence. So <ctrl-shift>U221E will produce the infinity sign, .

In Mac OS X to enter Unicode you go to System Preferences | Keyboard | Input Sources. Then click + to add a keyboard input source. Select and add the "Unicode Hex Input". To find this input source use the search box rather than trying to scroll though the lists (If you insist, it is under Other at the very end, after Welsh, and not in alphabetical order). Later you turn on the Unicode input method. Once activated you can type hex input by pressing and holding the Option (alt) key while typing hex values. Note that as of 2016-02-18 Mac OS X does not support hex codes longer than 4 digits. So, unfortunately, you can't enter the perfectly valid and official Unicode Vulcan salute, 🖖'U+1F596, but you can try to get by with ש (Hebrew letter shin, U+05E9).

Common characters that people often get wrong.

Some symbols look the same as their counterparts in the Greek alphabet, but these are actually seen as different in Unicode. These do not decompose as equivalent or compatible. For example, if you mean Ohm you should use the Ohm sign, not the Greek Omega. Probably this makes little practical difference in the real world. Any sort of semantic search indexing system probably has special cases for Greek letters used in other contexts. This can affect sorting and lexical indexing, but again, I can't think of any instance where this would actually cause a problem. Some fonts might be complete for some code points in the code space, but not others. I've not seen any that have the Greek letters, but not the Mathematical signs. So really, you want to use the correct symbol just to be correct, smartypants.

Some Useless Unicode Symbols

Greek Question Mark. U+037E. Although this may be canonically decomposed to a real semicolon (U+003B), this is not required and I am not aware of any IDE text editors that automatically normalize Unicode. The Greek Question mark can really screw up C, C++, Java, and anything else that relies on semicolons for syntax. This may be taken as an invitation to mayhem.
