The author itself is probably ai-generated. The contact section in the blog is just placeholder values. I think the age of informative articles is gone

there was a php-only million-rows challenge that was posted here recently. This uaf offers the opportunity for the funniest solution.

i feel that most of my problems in this space would be solved with better "fuzzy" search integration in obsidian. Some sort of local rag on my daily notes would be very effective.

do you know if such a project already exists?

There is an existing project that tracks and gather syscalls in the linux kernel, for all ABIs: https://github.com/mebeim/systrack . The author maintains a table here, which is incredibly useful: https://syscalls.mebeim.net/?table=x86/64/x64/latest

what do you think you will get out of this? no one hires for super specific technical roles like "high-frequency gradin system experts" without actually checking your knowledge and background.

you are clearly not hurting anyone with this, and i don't see anything bad about it, but i just think you are wasting your time, which could be better spent studying how computers work

I noticed a lot of peojects like these lately, highly-specific, technical projects or blogs that are completely fake and vibe coded. I wonder what people think they will get out of this. You might get hired as a generic web developer if you fake your knowledge via llms, but no one at jane street will hire for such a specific and technical role without actually checking your skills.

Very cool! I built something similar a long time ago: https://morse.halb.it and it blows my mind that it's actually being used by people

It's an interpreter, but it does support JIT to x64 and arm. There are some details here: https://github.com/jart/blink/?tab=readme-ov-file#technical-...

On the x64-playground website it's just running as an interpreter, inside of web assembly

This is mostly an educational tool, and it's intentionally designed to present data in a similar way to GDB. The idea is that students will use this tool to learn basic assembly concepts without the extra friction of GDB, and when they are ready they will move to the real tools, where hopefully they will already recognize some of the elements.

I am intentionally not implementing any useful feature beyond single stepping so that students will not remain stuck on a local minimum using this website.

I was gonna say, this sounds exactly like LLVM IR, except for the ease of use

Nice to see my playground trending! All of this is essentially made possible by the blink engine by @jart: https://github.com/jart/blink/ Which is an x86-64-linux emulator written in a few kb of c code.

There is no Backend server, everything runs locally in the browser in a runtime that weights less than a screenshot of the website itself!

To implement it I modified the blink emulator to run as a C library, and compiled it into a Typescript + WASM module that exposes an emulator API. Then I built a regular web app on top of it.
