Took a fun couple hours creating a function that does his slowest part as a service (not doing his work for him--we realized this needs to exist outside of his work) and then also making a parallelized helper for it.

Yep, 10-15x speedup using 16 cores. I think the operational machines have 32 or more cores, so this is great. Gets our final runtimes down to <1s (easy case) and <10s (hard case).

It's a good thing I brought the from yesterday home already or I'd be playing it right now instead of working (and now I'm talking about it anyway)

is bad enough, but I'm also much happier when I'm hyperfocusing

I can't even tell myself that One Day This Will Be Professionally Useful like some other recent focus points ( )

A 30-second 2nd stage engine burn takes the spacecraft over orbital velocity, quickly raising the altitude of the payload. In the next hour or so the speed will slowly decrease again, while the altitude will increase significantly.

@dave Someone was also telling mea about Stationeers, which lets you script pretty much everything in the game.

My quest is to use it specifically to teach basic-to-intermediate to non- people who are tasked with writing code to handle this type of data.

(As a myself, the arrogance of "i get paid to think logically" and laziness of "just tell me what to write" coders is appalling. You need to understand the problem domain!)

I'm following a tutorial for the build + launch + controls part but obvs that will go quickly and I can rely on my existing knowledge of (and brain the size of a planet) to get me the rest of the way.

I've crashed four times on this alone. All in exactly the same way. All while supposedly following the video instructions.

Had a very successful work trip. Met all the trip goals, plus the stretch goals, plus some icing on top of that. Also the remote site was impressed with the system and now associates my face with it (like our local site does), which isn't fair to the rest of the teem but doesn't hurt me any.

Boss described himself and *his* boss as "10dB happier". It's nice working for other

I wonder if that's correct. I guess I'm going to run with it for now. I'll use that to calculate a 4G burn time. :D

The orbital mechanics and maths behind the current sequence of solar eclipses that occur on the Solstice: why we see them every 19 years for now and then will not happen for over 180 years.
