Revived my 2017 dell XPS 15. The #omarchy experience has been amazing. Perfect weekend project.
Love this laptop to death, the 4k screen and the keyboard is amazing, but years of windows updates hade left it unusable.

Cool things you need to say to sound like a pro graphics programmer.
1. Micros and Mills ( time )
2. Order of magnitude ( a lot more )
3. Temporal ( over time )
4. Stochastic ( not over time… )
5. Deferred ( not now, but kind of now )
6. Immediate ( not kind of now, but now )

The truth about ECS is that you will only see improvement once your game/system logic bottlenecks on the ”many of the same stuff” problem. A problem you rarely encounter in gameplay for say a demo or small game

I’m staring to wonder if ECS as a concept is oversubscribed. I see a lot of new game devs implementing ECS for there first game projects as if this was a necessity rather than a performance optimization.

Reading up on common aspect ratios, thinking about ”cinematic” cameras based on the ”gameplay” controversy in the new GTA6 trailer.
This article on red was a very nice read, (with a little bit of subtle attitude?) hade no idea they use to store audio on film for ”talkis” neat compression

I crazy how alien humans must be to computers, a phone call for instance.
They transmit wave in digital patterns between us, and we SOMEHOW interpret that as information exchange. Detailed enough and lossy compressed yet still it almost encapsulates everything know to us and them.

Cubemaps or octahedron, that is the question. Found this old gem on AMDs blog. While mipmap gen would be simpler, and octahedrons fell more elegant, my intuition is that I won’t see a big delta. But how knows
Fetching From Cubes and Octahedrons
For GPU-side dynamically generated data structures which need 3D spherical mappings, two of the most useful mappings are cubemaps and octahedral maps. This post explores the overhead of both mappings.

I currently have all my hobby project in private GitLab repos. I should probably post them on GitHub, but it feels wrong posting something that’s not finished. Yet that is the whole point of a repo

Claud has been not very helpful with coding recently, but LinkedIn English seems to be a perfect fit. It’s all about linear regression. 🙃

I have very split feeling whenever I try to accomplish something with AI, it ultimately (so far) fails or is incomplete despite my best effort.
On one hand I’m sad I did not get the thing I wanted, on the other I feel like I get to keep coding for an other decade.

Having a hard time finding resources on anisotropic reflections. Lots of cool implementation for spec highlighting but nothing on let’s say sampling from cube or sh. Plz help?

Was coding over parsec and accidentally wrote “u32 arr[0]” and try to defer it. What dos it become, what is it even. I’m in existential crisis over this typo

Is there still no better option than "HLSL Tools," or have I missed something? With all due respect to the author, Microsoft, AMD, or NVIDIA should have invested in the IDE situations by now, right?

Moved over launching raddbg from my build.bat script to the build.exe it self. Marginal improvement but at least I can shut down the prev running session while compileing

Just put in my order for a 9950x, upgrading from 3950x. Will be very interesting to see what compile time will be like.
