I still use vanilla Claude Code without MCP or skills, am I in the minority? Not trying to be a luddite.

Just getting into homebrewing / jailbreaking old handhelds and consoles, and I really do feel like I missed a golden age of hacking that I would have loved. That said, I don't know if the tenacity I had back then would be enough to endure the steeper learning curve. Still, I would have loved to see my own work running on my DS.

I don't have an issue with the style personally. I actually like being able to navigate the whole page without clicking through pages. Looks like the content is the same too? Although that's just a glance comparing random snippets.

Despite the timestamp, I originally uploaded this a day ago and can no longer edit the title. My bad! I didn’t notice how dated the page was until it was too late. Thanks for the link, I’ve been mulling over getting a DSPico to tinker on my old DS.

Seeking a junior/entry/mid role at a startup or contract work. I interned at Google and have worked with a YC-backed startup. I can do full stack and have interests in systems engineering, distributed systems, and AI engineering.

Most recently, I built an operating system that plays Pong (https://github.com/Daves1245/horizonOS). I'm currently working on implementing the transformer architecture from scratch, and plan to make my own inference engine as well. My other projects include a multiplayer leetcode site (https://ternarysearch.com) inspired by binarysearch.com, a discord bot to answer questions about a github repo using RAG, a shabby discord clone to learn system design, a community-driven site that vibe codes itself, and home labbing.

New comment by medbar in "Death to Scroll Fade"

medbar — Wed, 18 Mar 2026 17:10:17 +0000

Not sure if I second this or not. I did want to scroll, but I don't know how much of that was influenced from the context or the extreme minimalism making me want to look for more - I'm interested in how I would have reacted to the site not knowing it had scroll fade. I could see an argument with the "Don't Make Me Think" principle.

Gladly! Since my last comment I added sound support through an ac97 driver. It was fairly straightforward in hindsight, only had an issue with the interrupt not being handled - turns out my ISR stubs weren't fleshed out to handle IRQs, just the cpu exceptions. Also had a minor bug where addresses outside of the kernel weren't getting translated properly, which I hadn't tested before and assumed to be correct.

I probably could have saved myself 2+ hours of debugging if I had simply stopped working off of assumptions that my driver code was wrong (it was, but that just took reading the spec and checking out some drivers for reference) and doing a root cause analysis with `objdump` or through QEMU. Still surprised how far you can go with vanilla debugging prints - when I started this project, I was sure that I'd become fluent in gdb as a byproduct, but I stopped using it once it would break when the stack became corrupted and haven't tried it since.

Discussion is the reason I made the jump from lurking to having an account on HN. Happy to talk - reached out to you on twitter. And good luck to you as well :^)

Very cool! I just added a ps/2 keyboard driver to my kernel and I’m looking into scheduler / user mode and FAT filesystem support at the moment

Seeking a junior/mid dev role at a startup or contract work with ~1 year of experience. I was part of my university's programming team and my team won the ICPC Southeast regionals Div2 contest. I interned at Google for the Network Doctor team and have done frontend freelancing work for a YC-backed startup.

Most recently, I've added a keyboard driver to my hobby OS project I'm writing Pong in (https://github.com/Daves1245/horizon). My other projects include a multiplayer leetcode site (https://ternarysearch.com), inspired by binarysearch.com, which I'll make open source to give to the community if/when I'll move onto something else, a discord bot to answer questions about a github repo using RAG, a discord clone to learn system design, a community-driven site that vibe codes itself, and home labbing.

I just finished adding uACPI to my hobby OS and have all the pieces necessary to write up a crude version of Pong. Since pong was my first ‘real’ project when I started teaching myself how to code, this has that extra bit of sentimentality for me :)
