@charles_irl Ya’ll do influencer partnerships 🤔?

Asking cause I run a C++ deep-dive YT channel with ~30k subs and ~150k monthly views.

[Suboptimal Engineer @SuboptimalEng]

@EIiasNajarro Nice! Did you use TS or Rust to make it?

[Suboptimal Engineer @SuboptimalEng]

Did you know about the compiler optimization that PREVENTS moving the stack pointer for a leaf function?

I certainly didn't and was confused reading the generated x86 assembly.

C++ deep dive on my YouTube channel 🫡

[Suboptimal Engineer @SuboptimalEng]

Ever wonder how C++ stack frames get created and destroyed? Or how %rbp and %rsp work?

I go over the details by stepping through some x86 assembly in LLDB.

C++ tutorial is on my YouTube channel 🫡

@TheCherno This would be interesting! Would you use WebGPU?

[Suboptimal Engineer @SuboptimalEng]

@arpit_bhayani Awesome, congrats 👏

C++ WebGPU Shader Engine (part 19)

Here's a demo which stitches frames together using FFmpeg. Each image was auto captured during a hot reload.

Please excuse the 2 FPS, that is by design. The goal is to have a tool that can show the iterative process of shader development!

[Suboptimal Engineer @SuboptimalEng]

C++ WebGPU Shader Engine (part 18)

Implemented a feature to capture images whenever I hot reload a WGSL shader!

The goal is to use FFmpeg to stitch these images into a video. This reduces the number of times I need to open screen capture to record.

@rpandey1234 Congratulations 🎉 🔥

[Suboptimal Engineer @SuboptimalEng]

Made a 12 minute tutorial going over how to set up and use the C++ debugger in VS Code. Video is live on my YouTube channel!

@XorDev Very cool! Not having to copy paste is gold 🥇

[Suboptimal Engineer @SuboptimalEng]

C++ WebGPU Shader Game Engine (part 17)

Spent the last 2 days cleaning up tech debt created from mindlessly copy pasting AI generated code.

The project is finally at a good pausing point! Here's one final demo (for now).

C++ WebGPU Shader Game Engine (part 16)

Added the Sobel filter as a post processing effect.

[Suboptimal Engineer @SuboptimalEng]

C++ WebGPU Shader Game Engine (part 15)

Swapping noise textures.

[Suboptimal Engineer @SuboptimalEng]

C++ WebGPU Shader Game Engine (part 14)

Finally working on an option to import noise textures.

Code is complete AI slop. Need to fix it at some point.

[Suboptimal Engineer @SuboptimalEng]

@CoreDumpped On a side note, love your videos btw!

[Suboptimal Engineer @SuboptimalEng]

C++ WebGPU Shader Game Engine (part 13)

Couldn't stop myself from adding more features.

Using the node editor seemed a bit excessive so I implemented a simpler way to add and customize post processing effects.

@neetcode1 Interesting idea, never about it this way before!
