cloudheadon Ask HN: What are you reading?

Did you start the silo book? Loved the show as well.

Thanks for explaining!

Did you have to look or review any of the code produced, to get the performance/capabilities that you wanted, or were all interactions through CC? In other words, did you hit any walls with the pure agentic workflow?

cloudheadon Ask HN: What Are You Working On? (March 2026)

I’m working on Radiant Computer: https://radiant.computer — a new from-scratch personal computer and OS.

cloudheadon Understanding the Go Compiler: The Linker

The title is misleading

cloudheadon Zig – io_uring and Grand Central Dispatch std.Io implementations landed

Can you elaborate? Zig has a lot of traction already.

cloudheadon Fix the iOS keyboard before the timer hits zero or I'm switching back to Android

Uhm yeah, a touch screen is not a keyboard. It will never be one.

cloudheadon Vitamin D and Omega-3 have a larger effect on depression than antidepressants

So 5000 IU is the recommended amount?

cloudheadon The secret medieval tunnels that we still don't understand

Hyperion, anyone?

cloudheadon AI is forcing us to write good code

What's MC/DC?

cloudheadon Static Allocation for Compilers

How does this work? Files need to reference other files eg. for calling functions from other modules, which means semantic analysis needs both files in memory to check the types. This is especially complicated with mutual recursion across modules (separate compilation doesn't apply here). If you're building a language like C where everything requires forward declarations, then maybe, but anything more modern seems difficult.

cloudheadon Rust errors without dependencies

I think you’re right with regards to the intention — but I’ve personally not experienced the case of an std lib being too big — good examples of “the right size” would be Go or Zig.

cloudheadon Rust errors without dependencies

The fact that you either need a third party dependency or a large amount of boilerplate just to get decent error reporting, points to an issue in the language or std library design.

I've started also dropping `thiserror` when building libraries, as I don't want upstream users of my libraries to incur this additional dependency, but it's a pain.

cloudheadon Functional programming and reliability: ADTs, safety, critical infrastructure

False dichotomy.. if reliability matters, you have to invest in both. Fault tolerance is not a replacement for correctness.

cloudheadon A guide to local coding models

What’s wrong with your keyboard haha

cloudheadon A guide to local coding models

For sure, and I guess that's kind of my point -- if the OP says local coding models are now good enough, then it's probably because he's using things that are towards the middle of the distribution.

cloudheadon A guide to local coding models

In my experience the latest models (Opus 4.5, GPT 5.2) Are _just_ starting to keep up with the problems I'm throwing at them, and I really wish they did a better job, so I think we're still 1-2 years away from local models not wasting developer time outside of CRUD web apps.

cloudheadon Jonathan Blow has spent the past decade designing 1,400 puzzles

And your point is? Shipping garbage is better than not shipping anything?

cloudheadon Ask HN: What Are You Working On? (December 2025)

https://radiant.computer

A new vertically integrated operating system and computer for the next generation.

Working on the native language and OS currently!

cloudheadon Show HN: Detail, a Bug Finder

Looks interesting, but I self host so it would have to work with plain Git URLs.

cloudheadon Why we built Lightpanda in Zig

> LLMs deserve a 100x better browser.

Hold on, why can't humans have a 100x better browser?

cloudheadon The Ethical Computing Initiative

Nice, this aligns with what we're working on at https://radiant.computer -- it would be nice to gather all such projects in one place.

cloudheadon Ask HN: What Are You Working On? (Nov 2025)

I’m working on Radiant Computer.

https://radiant.computer

It’s a new kind of computer that attempts to part from the unix heritage and offer something really accessible and modern.

cloudheadon Radiant Computer

Yes, good idea — I know about Rebol but haven’t looked at it from that angle.

cloudheadon Radiant Computer

Thanks for your comment.

I do think Linux is good enough (it's what I use daily), but I'm a software person. I don't think linux is good enough for the average person or for kids learning how to use computers. It's hard to use and quite unfriendly, even distros like Ubuntu.

The second point is simply that I think we can do better. Progress does not stop here, but most people are afraid to take on big problems, so they never try.

cloudheadon Radiant Computer

In five years time, "I want AI" will be 99% of computer users. Sure, neural nets are opaque, but having an AI assistant running locally and helping you with your tasks does not make your computer any harder to understand.

cloudheadon Radiant Computer

Thanks for the feedback. My goal at this stage is to put the full vision out there, and refine it to create a sense of direction, a north star under which to work. A lot of the specifics are undecided/unknown and that's ok at this stage. I'm building this bottom up using the skills I have (software), and as I bring on hardware folks, those aspects of the system will start to clarify as well.

Whether the project is bigger than I think or not is not so relevant for me personally, I will attempt it because I don't see a future in personal computing that I want to be a part of otherwise.

cloudheadon Radiant Computer

I agree! I've been thinking about why terminal software is so compelling, and how to make that the default while keeping the system accessible to beginners. I think there's a way to do it, to unify GUI, TUI and CLI.

cloudheadon Radiant Computer

That's a nice approach, thanks for the advice.
