Interesting! When you say executive functions, could ADHD be linked in a way to this? When I "zone out" it feels like REM dreaming while awake.

Not velocity - momentum is what is conserved. So the black hole could have absorbed the equal and opposite momentum, but being more massive, not gained much velocity. Or, a hypothetical scenario in separating the two it could have flung t

I'm currently reading the book "Fall, or Dodge in Hell" by Neal Stephenson. Speaking in general terms to avoid too many spoilers, there's a scene where it's strongly implied one character is responsible for the dea

I'm currently reading Fall; or, Dodge in Hell as my first Neal Stephenson book. I will say the plot summary doesn't do it justice. Regarding the setting the in mid-point of the story, with the split between reality-based soc

I saw this come up in a playlist of clips about programming. I was so confused, especially because I had thought I was watching a user curated list, until I saw that.

I worked at a satellite office of a medium software company. A fellow programmer asked for more time off instead of pay raises. He was put on a shitlist for even making that request. The company HQ was in a college town where there was no

I think Microsoft Access has a lot in common with Javascript. Both are Lovecraftian horrors that no sane person would (clean-sheet) design in their current form. Both derive their ubiquity from having been the only or nearly the only opti

I'm eagerly anticipating the day when hobbyists can 3-D print engine blocks and cylinder heads. Imagine the engine swaps enthusiasts will come up with when they can make their own designs from scratch and share high-performance design

A similar situation applies to 3D graphics for game engine programming. You'd think if a piece of hardware can run a AAA game with impressive graphical effects at 60 FPS, it should be able to run your simple indie game engine with sim

They must have either bought too many or excessed some chips that didn't test perfect, because when I did my NASA internship around 2007-08 an electronic's surplus store in Houston had boxes of 8086 chips, 8088's as well. I

Kind of in the same vein, some code I was porting to a newer C++ compiler had "int error = get_status(x);" and I got a warning that the variable "error" is never used. So I commented the line out. After I finished fixi

A few years ago I had the itch to do this and got as far as buying a hardware development kit one of the NXP LCP chips. They're low power ARM CPUs available in LQFP form (so theoretically hand-solderable) and it should be not hard to

All depends on which microcontroller it is using. The Propeller microcontroller has multiple cores and specialized registers for video, so it can just dedicate independent core to video and bus control. An Arduino is certainly fast enough
