Consider the Flash, with the speed and reaction time to pluck bullets out of the air. That wouldn’t keep you from getting shot in the back of the head with a supersonic round with no warning to react to. He could constantly look around, swiveling his head at thousands of RPM to look everywhere, which would be an interesting visual effect, but another option would be to compress a 360 degree visual field into the straight ahead view. There have been novelty “see behind you glasses” forever, but AFAIK, there haven’t been any attempts at giving full 360 degree vision. There have been experiments where psychologists put mirror glasses that flipped the visual field on people to test the adaptability of the brain’s visual system, and it was found that the view change was initially incapacitating, but over the course of a couple weeks, people could adapt to it. Taking them off then took a couple weeks to fully retrain for normal vision. For the Flash, it couldn’t be a camera-and-screen pass-through VR system, because you would need thousands of frames per second to accurately estimate the trajectory of a bullet, but a purely reflective system of curved mirrors could do it.  A non-linear warping would be harder to adapt to than a simple mirroring, because different eye positions would have different distortions. For conventional human reaction speeds, pass-through VR systems with eye tracking could compress everything into the peripheral vision and leave the fovea untouched, which would probably speed adaptation significantly. I can imagine special forces teams having to wear their 360 vision helmets for a couple days prior to a mission, akin to deep sea divers having an extended prebreath and decompression phase. @PalmerLuckey The comic-friendly fix is to just assume that the Speed Force gives the Flash an awareness of anything moving fast in his vicinity, although another thought I had is that while the speed of sound in air is only 330 m/s, the speed of sound in the ground is almost 10x that, so you might be able to “hear a gunshot” with your feet well before you could with your ears.

@zack_overflow org-mode is awesome, it’s not really emacs. Been there and still using emacs just for org-mode. I don’t believe one editor fits all use cases

My hot take is: Emacs is better than neovim - The ecosystem and tooling is better, neovim is still catching up. - Evil mode lets me have my Vim keybindings. - ELisp is better than Lua. This todo list is rendered with org-mode and it's awesome

Inspired by John Carmack's .plan files, the past 3 years I've made todo files for every project And today it finally paid off 6 months ago I was in the middle of a refactor but set it aside Today I wanted to finish it, but forgot all context, but I had all my steps and notes

@FlohOfWoe Now that sounds interesting. The guys from haxe had this for years but not as part of the stdlib. Any idea which backends it support?

Revamped the gratuitous explosions and particle effects to the code editor I'm building And added sound effects! (Sound on!)

5 intersecting rotating cubes, cpu-rasterized in correct order thanks to a custom depth buffer (aka uint32_t[width*height]). Right side shows the actual depth buffer values. This works at a miserable ~25fps, but at least it works 😅

Inktober Day 20 - Uncharted "Aye, the Iron Gull sailed into the Misty Deep, those waters no map dared mark," the old sailor whispered over his mug. "T’was the last time anyone saw her, swallowed whole by a kraken’s tentacles. Not a single soul left to tell the tale." #inktober #inktober2024 #gamedev #kraken

@mikekasprzak I guess it was just a temporary glitch on my side. It started working again in an hour or so

@pikuma I am on the same boat. vi used to be the only sane text editor when working on console unix terminals back then. And some things just stick.

I had to go to win32 hell and back to pull this off but it finally works!! my modeling tool now has a custom title bar! while still also supporting resizing, title bar dragging, and all those nice window features! this is nontrivial for some reason!!
