Having Git permissions per subfolder

TLDR: I experimented with a way to allow Github to have permissions (including read permission) per subfolder here.

k8s and EKS tips I gathered so far

I wanted to share some tips I learned along the way about K8S and AWS EKS.

The crazy ideas section - Using M1 Apple GPU as "AVX" extension

After the last post in this section relatively successful

Which was brought to Defcon

I want to continue the trend :)

Apple M1 is much faster than what people thinks

Hey,

I experimented the other day with some algorithms that were written in Akka and Golang (https://breaking-the-system.blogspot.com/2022/10/how-we-can-learn-parallel-computing.html), which is highly parallelised/threaded. I tested those against 2950x/3960x AMD ThreadRippers and against Apple M1 + M1 Max. The results were really shocking for me. The Apple won (by a long shot) the ThreadRippers, even when the TRs were OC to 250W and 350W+ and they are one the fastest CPUs money can buy for their time and costing so much more than the Apple one (not considering the insane cooling/electricity they need) and the algorithm is highly parallelized.

How we can learn parallel computing from computer games

I really like computer games like Factorio or Satisfactory In those games you have to mine your planet resources e.g iron/copper/uranium/coal and put an intricate supply chain of factory machines/betls until more complicated resources come out e.g copper wire, engine, fuel, etc'.

Here are a few screenshots:

AWS EKS 502 503 504 gateway errors and pricing

I have used K8S for quite some time now, and I actually quite enjoyed it, but like every good piece of software, AWS has to come and fuck everything up.
