  • Yup and I am getting sick of hearing this even on Arch Linux. Like, mofo, you could literally run a snapshot or backup before upgrading, don’t blame us if you’re yoloing your god damn computer. Windows have exactly the same problem too and this is why we have backups. Christ.

    On my Arch Linux Install, I literally have a Pacman Hook that would forcibly run backup and verify the said backup before doing a system-wide update.








  • Yup, been writing a new shader language to replace GLSL and HLSL for Vulkan Compute purposed, but I eventually switch from SPIR-V IR to MLIR and use IREE Compiler which accepts the MLIR and compile it to any of CUDA, ROCm, SPIR-V and so forth.

    A lot of it was because of my unadulterated hatred toward our current Machine Learning Frameworks...

    It’s one of the project that I’ve been working on to outright replace Pytorch/Tensorflow and ban those two framework from my office forever. I got fed up not knowing how much exactly do I need in memory allocation, computational cost, and so forth when running or training neural net models. Plus I want an easier way to split the model across lower-end GPU too that doesn’t rely on Nvidia-only GPU for CUDA code. I also wanted to have SPIR-V as a fallback compute kernel, because if CUDA/ROCm is too new for GPU, you’re SOL, but if you have SPIR-V, chances are, any GPU made in the last 10 years that have a Vulkan Driver, would likely be supported.

    One of the biggest plus with MLIR is that you are also future proofing your code, because that code could feasibly be recompiled for new devices like Neural Net accelerator cards, ASIC, FPGA, and so forth.



  • I agree on avoiding on the idea of avoiding having to make your own parser generator, this is precisely what I’m doing and it’s hell. I assumed that you probably want to pick up some understanding on how parser differs when it come to writing grammars. As for ease of use and requiring the least understanding, using something like Earley parser is probably the easiest, it would be slower than other parser algorithms, but it could handle ambiguous grammars making it ideal for first timers to learn how to write a programming language.


  • Yep, and if open source licensing could be revoked on a whim, you can imagine the chaos that ensued. That would be my understanding as well, old version that have MPL license is perfectly fine to fork off, newer version might not be as it is under a different license. One of the reason why I liked Apache License is that it have make it explicitly clear that it’s irrevocable whereas MPL it is operating on an assumption that it’s not revocable. The most fundamental problem with the legal system in USA is that no law is “set in stone” and leaving things to assumption is open to reinterpretation by the judge who may have sided against you. (Hell, Google vs Oracle on Copyrighted API is still on case-to-case basis, so take it as you will.)

    Disclaimer: I am not a lawyer. I just share what I learned from Legal Eagle youtube and few other sources.



  • I concur, there was a few problems that might come up on various platforms like Windows not implementing C11 standard threads and other stuff, you would instead use TinyCThread library that works like a polyfill.

    All problems and challenges are workable, if the problem with Debian is out of date library, you could set up CI/CD for release build that rebuild your software when update occurs and static link the updated dependencies.

    Back to your point, if they didn’t design their code and architecture to be multiplatform like in C, they need to re-evaluate their design decisions.



  • It’s incredibly difficult task to master/learn an old technology or an old concept that aren’t documented well. For an example, parser algorithms are very well known for being too verbose and unnecessarily over-complicated in documentation, if you ask anyone you know in the programming community, for the next 100 people, they wouldn’t know how to implement LALR parser or Earley parser even if they graduate from university with a computer science degree.

    One of the way I use to learn a concept is writing a full manual of it in LaTeX in a way that I am explaining every single aspect of it to a layman and how it can be implemented in every way as well as providing examples in C code forms. It’s a bit interesting that you sometime learn better by trying to teach it to a made up audience when writing a manual.
