Huh. Neat.
Looking at my disassembly for an odd performance case, I see:
movzx ebx, bx
Easy way to clear out high bits.

JR East has a game where you drive a train?? Neat.
Whoooaa each additional line is a $27 DLC??
I guess that makes sense. The graphics are insane and they seem to have modeled every building.
WAIT! It's a video!!

Color experts,
suppose I have an image in X color space that I'm displaying on a monitor with Y color space.
I think scaling each component independently isn't quite correct.
The triangle of the primaries might be "rotated".
But maybe close enough?

I feel like some UI problems are well solved,
buttons, scrolling...
But others seem unsolved still.
Like mode changes, for example.
Suppose you are driving along and your engine develops a problem. A modal dialog covering your speed is no good. Designated notification area?

My vertex shader had:
pos = vector * matrix;
The translation looked like a rotation.
Because the order matters there and I needed:
pos = matrix * vector;

Watching him speak gave me some insight into his thought process and intentions. New role model. Thanks @jenson.org

So I knew in C++ you could spread a string across lines.
"This is"
" one string"
" with no newlines in it"
But I didn't know you could insert comments. Neato.
"Hello "
// Is "World" appropriate?
"world"
"This is"
" one string"
" with no newlines in it"

Been learning Go through boot.dev .
(I've wanted to do something like this so happy to see their implementation and support them.)
I like several things Go does. The multiple named returns is nice.

HDR is difficult.
I have a XB273U NV. It supports HDR 400.
When I play PQ content on it, it seems fine.
I also have a PA32U which is a MUCH better monitor for HDR. Better color accuracy, 1000 nits...
PQ content is too dark on it unless I put it in HLG mode???

Remember a little while ago when China was buying GPUs and putting more RAM on them for AI servers?
And now we have a massive RAM shortage.
China is pretty good at seeing what they need and making it happen.

I friggin' love @tsoding.bsky.social .
I've been a graphics programmer for years and didn't fully know what you taught--step by step--in your last video.
Thanks, friendo.
Also, somehow I only just noticed your i3status: Tea, Leaked IP.

Things like the NORAD Santa Tracker warm my heart.
But uhhh any chance some of us graphics programmers and artists can contribute? Look at the way those reindeer animate. "Skinning" has been around since the late '90s.

This might be a spicy take, since everyone hates AI...
but I'm okay with AI for iterating on ideas.
Not for final production things. (Although, I could see it becoming good enough some day. And we'll have have to face what that means then.)

<me, a year ago> 1Gb networking is fine for me. 2.5Gb or 10Gb would just waste more CPU I think.
<me, today> RDMA is making a lot of sense to me. And 10Gb just isn't enough.

That whole Amazon using keyboard lag thing...
That means they basically have a keylogger on their worker machines. Which I guess is ...fiiiiine.
But wouldn't traceroute have worked, too??

If you write to the AX register, the high bits of EAX are preserved.
Same when you write to AL--the high bits of (E)AX are preserved.
But when you write to RAX, the high bits of EAX are zeroed.

Interesting Notepad feature I'm sure all us programmers will hate:
I wanted to break up a line.
I accidentally pressed backspace one too many times, turning the word "reason" into "reaso". Then I pressed enter.
Notepad put the "n" back to complete the word.

I think I bought AoE 3 on the XBox Game Store?
Which is shut down and now I no longer have access to it? It wasn't transferred to the Microsoft Store, I think.
(Possibly because only the Definitive Edition was added to the Microsoft Store?)
If correct, strong argument for GOG or Steam.
