Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tech I am learning in 2024
Thanks to cpu.land , I grew an uncanny interest in how cpu works and got me deep into operating systems from there, it’s fascinating to see the deep down of your computer to the levels of registers and ALUs(arithmetic logical units). Nand2tetris and OSTEP is the greatest resource for starting with operating systems.

Ask HN: Who is hiring? (February 2024)
OrbStack | Founding Engineer | US/Europe REMOTE | Full-time | https://orbstack.dev
OrbStack is making Docker containers & development environments delightful. Our app replaces Docker Desktop and makes containers faster, lighter, and easier to work with. It's the tool of choice for PlanetScale, Replicate, and other hot companies.
Containers should be a joy to use, not something you have to put up with. Let's build the future of dev envs.
As a founding engineer, you'll mainly work on breaking high-level ideas down into tough systems problems, solving them, and taking ownership of projects. If https://cpu.land and https://docs.orbstack.dev/architecture excite you, you'll be right in place.

Show HN: How did YOUR computer reach my server?
Hi! I'm Lexi. I'm 17, and one of the things I'm interested in is gaining a deeper understanding of how computers work and showing that in new ways. A few months ago I published https://cpu.land (discussion: https://news.ycombinator.com/item?id=37062422).
After cpu.land, I felt a lot of pressure to make another Big Giant Thing but didn't really have anything compelling. So I just hacked away on personal projects and, through some coincidental learning on how the Internet works, ended up hacking together a traceroute program that could live stream to a website from scratch!
I realized I had never seen this sort of thing on the web before, and it was actually a kind of cool and novel way of visualizing the structure of the Internet, so I polished it up and built a pretty site around it. In the process, I learned some really interesting things about how BGP and the structure of The Internet, so I melted the traceroute tool with an article sharing that knowledge.
I'm still hacking on this and I'm sure my code will manage to break somehow, so please let me know if you have any suggestions! :)
(Side note: why Rust? I don’t think programming language choice matters that much, but I wanted to quickly write a very dependable low-level program, and I really like Rust’s error handling primitives.

When AI creates its own code, why would it use a programming language?
No this is just false. They are not being converted to machine code. But maybe we are getting tripped up on language here. Machine code, to me (and everyone else with a background in computer science) means something specific -- something like x64: https://www.felixcloutier.com/x86/ . This is absolutely not the representation that is being used for prompts or anything like it.

I need to know x86 assembler good enough to parse gcc output where should I start?
To understand the instructions themselves, I mean all instructions nothing beat the Intel manual but you probably don't want to read it for such use case. This less complete reference might be better suited for you: https://www.felixcloutier.com/x86/

Milestone Completed: Firefox now has JavaScript JIT acceleration for RISC-V (RV64GC). Patch upstreamed.
Meanwhile here's x86. There's roughly one thousand instructions if you ignore various size prefixes/suffixes and many more if you don't.

Do any of these classes have their material online?
I don't think CS 261 has an online posted anything available prior to you doing the class, but I could be wrong. But here's a gift from me to you that you'll want for the class: https://www.felixcloutier.com/x86/

How can I create a disassembler for basic x86 (not x86-64) ISR?
I recently got interested in developing low-level stuff, like kernels, operating systems, and others. So, I want to create a disassembler for learning how machine code/assembly code in x86 is truly like. While trying to find documentation for the x86 platform, I only found confusing documentation that didn't help me reach my goal. Do you guys have any websites / documents that helped you create a disassembler? Any suggestions are welcome.
