Woooooow.
I wonder how much Twitch got paid to put Roblox in its top level naviation.
Back when I worked there, I was tasked with adding an in-nav ad to the Android app. I hated it. At least we would only show it if the user didn't have Twitch Turbo (no ads).
This shows WITH Turbo.

Microsoft made its docs open source, right? I can update it?
This says D3D11_USAGE_STAGING is for GPU -> CPU.
But it is either direction? And most typical usecae is CPU -> GPU, right??

D3D11_USAGE (d3d11.h) - Win32 apps
Identifies expected resource use during rendering. The usage directly reflects whether a resource is accessible by the CPU and/or the graphics processing unit (GPU).

I'm learning 3d modelling (not creativity/art--just tooling).
A lot of this seems to be knowing what steps you need in what order. If I prep this step, I can unlock the clean way of doing next step.

Roblox has more concurrent players than all of Steam games combined.
I am struggling to fully internalize that.
Being the platform is currently VERY useful for Roblox & Fortnite.
That will fade. But it is still wild.

In Windows, UIs are now just textures (simplifying).
So for performant UIs, you embrace and write a renderer.
Which means part of the graphics driver is now in your memory space and you have 20 extra threads...
I miss when the only program running on my computer were ones I actively chose.

Yesterday, I pointed out to my friends that Intel beat earnings per share by 81.51%, which is crazy.
Today, their stock is down 17.75%.
Nothing makes sense.

It is both neat and annoying to watch my ISP fail over live.
The yellow dotted line is latency to Microsoft, Google, and Cloudflare servers. It has consistently been around 18ms.
Then at 10:10pm ET it jumped up to 27ms and has stayed there for about 2 hours.

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.

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:

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.
