aviation, international date line
I saw that Qantas is restoring their Sydney to Santiago flight, their only connection to South America.
This takes 13 and a half hours to cross the South Pacific, landing 90 minutes before it takes off thanks to the international date line. :D
No in-flight wifi service though... bring a book or something to watch!

Retro computing programming language stuff
taking a look through the atari memory map, a 48 KiB machine should allow for 8 KiB of code (either cartridge ROM or loaded from disk) and at least 24 KiB of data pages, to be divided between stack (fixed pointers) and heap (LISP-style nodes).
The stack serves as the garbage collection roots and storage for locals & return records.
flight sim
Took a flight sim break and did one of my comfort routes: VFR from KSNA (Orange County) to KPSP (Palm Springs). Takes about 45 minutes in a little Cessna or similar.
Sometimes I do this by going up to higher altitudes to go over KRIV (March air base), but I stayed around 3000-3500 MSL and went around it instead this time for funsies.
Palm Springs has mountains to the west, so when landing on a northbound runway it's a non-standard right pattern, which is always fun to "mix it up" :D
Retro computing programming language stuff
Also I can optimize the GC passes by putting a marker byte in the one free byte per page (51 5-byte nodes in 256 bytes). When flipping a node's GC state, set the bit corresponding to which of 4 states it is (3 GC colors or free).
Then the time-sensitive mark/sweep passes can skip pages with no nodes to process.
