cat-whisperer··on Beginner-friendly, unofficial documentation for Helix text editor
I think so too, a lot of my friends have told me they had a great experience with helix, but vim keybinds are rooted too deep, and it's also the sunk cost of having built the config over an entire year. But, I think I would give it a try sparingly.
cat-whisperer··on Why I'm teaching kids to hack computers
Started modding Android ROMs at 13. That age is perfect; old enough to understand consequences, young enough to not care about breaking things.

Hardware hacking tools have gotten more accessible since then. The Flipper Zero makes this easier now; 256KB RAM, open firmware, $200. Compare that to needing a full PC setup in the 2000s. Lower barrier, same curiosity-driven learning.

Guided challenges vs pure exploration; both work. The structure gets more people started. The ones who stick around will break out of the sandbox anyway.

cat-whisperer··on How I turned Zig into my favorite language to write network programs in
Stackful coroutines make sense when you have the RAM for it.

I've been using Zig for embedded (ARM Cortex-M4, 256KB RAM) mainly for memory safety with C interop. The explicitness around calling conventions catches ABI mismatches at compile-time instead of runtime crashes.

I actually prefer colored async (like Rust) over this approach. The "illusion of synchronous code" feels magical, but magic becomes a gotcha in larger codebases when you can't tell what's blocking and what isn't.

cat-whisperer··on Unconventional Ways to Cast in TypeScript
I don’t get this? why do I need to say as const?
cat-whisperer··on Reasoning is not model improvement
I use thinking with claude cod extensively. It’s same as reasoning they just name it differently. It definitely helps, sometimes it feels like they came up with original thoughts and ideas
cat-whisperer··on Claude Memory
i rarely use memory, but some of my friends would like it
cat-whisperer··on Ask HN: What are people doing to get off of VMware?
docker is the way!
cat-whisperer··on Show HN: Duck-UI – Browser-Based SQL IDE for DuckDB
great timing, I am literally adding Clickhouse and DuckDB for my project. This is gonna be super handy for testing
cat-whisperer··on CMU Students Put AI Coding Tools to the Test
when I do it, professors call me out for cheating, when someone from CMU does it; it's a article!
cat-whisperer··on Show HN: I've built a tiny hand-held keyboard
love the design, it would be crazy if this becomes a thing!
cat-whisperer··on A small number of samples can poison LLMs of any size
People are already doing this by copy-pasting random stuff into their LLMs without thinking twice. I think the fixed number vs. percentage thing makes it way more practical for attackers. Would be cool to see defenses at the data ingestion layer!
cat-whisperer··on Python 3.14 is here. How fast is it?
Yeah honestly I don't really care about these benchmarks. Python isn't built for raw performance and that's totally fine! It's the number one choice for prototyping and can do so much, that's what actually matters. I think it's cool they're working on speed improvements though, means my prototype-to-production cycle gets a bit smoother lol.
cat-whisperer··on Two things LLM coding agents are still bad at
The copy-paste thing is interesting because it hints at a deeper issue: LLMs don't have a concept of "identity" for code blocks—they just regenerate from learned patterns. I've noticed similar vibes when agents refactor—they'll confidently rewrite a chunk and introduce subtle bugs (formatting, whitespace, comments) that copy-paste would've preserved. The "no questions" problem feels more solvable with better prompting/tooling though, like explicitly rewarding clarification in RLHF.
cat-whisperer··on Waymo has received our pilot permit allowing for commercial operations at SFO
I think this is a really exciting development for Waymo and the future of autonomous transportation. Imagine the next steps; waymo flights
cat-whisperer··on The Linux Process Journey (2023) [pdf]
I think telling about niche & hacky things that you can do in Linux is a great way to really learn the ins and outs of the operating system.
cat-whisperer··on Show HN: A zoomable, searchable archive of BYTE magazine
This looks hella cool!
cat-whisperer··on Google will allow only apps from verified developers to be installed on Android
I think the push for verified developers is a double-edged sword. I got into this space, precisely because of how easy it was for me with my pentium computer a decade ago.
cat-whisperer··on Show HN: Trying out industrial serif on my profile
I was looking to take it down, I don't think I can do that now.
cat-whisperer··on Show HN: Trying out industrial serif on my profile
My bad, I'll make sure to keep this in mind.
cat-whisperer··on Show HN: Trying out industrial serif on my profile
Instrument serif ya
cat-whisperer··on Agent-C: a 4KB AI agent
it would be cool to see, the AI agents directly calling the syscalls. lol
cat-whisperer··on A visual introduction to big O notation
I've found that one of the most effective ways to internalize big O notation is to relate it to everyday experiences.
cat-whisperer··on Show HN: WebGPU enables local LLM in the browser – demo site with AI chat
I've been following the development of WebGPU and its potential applications, and this demo is a great example of what's possible.
cat-whisperer··on Launch HN: Hyprnote (YC S25) – An open-source AI meeting notetaker
Dude, you should def checkout parcl.cloud
cat-whisperer··on Vibe code is legacy code
I've found that the real issue with "vibe coding" isn't that it's inherently bad, but rather that it highlights a deeper problem: our industry's obsession with explicit, step-by-step documentation.
cat-whisperer··on Stop SSL certificate outages with automated monitoring – Enterprise Ready
I use Caddy, and it handles cert renewal automatically for me, so I've never had to deal with SSL expiry issues. Pretty handy!
cat-whisperer··on Enough AI copilots, we need AI HUDs
I'm thinking AR glasses with AI HUDs and we're basically there - my to-do list just got a whole lot more interesting.
cat-whisperer··on Copyparty – Turn almost any device into a file server
I'm planning to use copyparty with Apple Shortcuts to sync my clipboards across devices - should make life a lot easier.
cat-whisperer··on The future is not self-hosted, but self-sovereign
I'm curious, how does blockchain play into being self-sovereign? Is the idea that decentralized networks can give us control over our own data?
cat-whisperer··on The many JavaScript runtimes of the last decade
I'm curious, how do these new runtimes handle async context tracking? Do they all rely on Async Hooks or implement their own solutions?
