Los Angeles just needs buses that come through frequently enough to obviate the need to check the schedule. Also dynamic bus routing, which would reduce the total number of buses required for this.

I think the alternative should be "this is not blue". I was served what I would call a "teal" or "turquoise" but the alternative button shows "this is green", which it was not.

This is one of those things that seems like a nerd snipe but would be more easily accomplished through brute forcing it. Just get 76 people to manually type out one page each, you'd be done before the blog post was written.

Why wouldn't a qualified developer just run the code? Takes two seconds instead of ... whatever you're going for here.

Dumb question but what stops browsers from rendering TeX directly (aside from the work to implement it)? I assume it's more than just the rendering

This was the original goal of the Cornell box (https://en.wikipedia.org/wiki/Cornell_box, i.e. carefully measure the radiosity of a simple, real-world scene and then see how closely you can come to simulating it).

For realtime rendering a common thing to do is to benchmark against a known-good offline renderer (e.g. Arnold, Octane)

New comment by percentcer in "A guide to Gen AI / LLM vibecoding for expert programmers"

percentcer — Fri, 22 Aug 2025 20:45:06 +0000

I like programming. It's fun, and sometimes it even requires creativity. There are plenty of times when it's not that fun, and doesn't require any creativity (because whatever it is has been done by someone else a thousand times over), and you just want a result. Vibecoding is great for _that_ stuff (think little throw-away scripts, shell one liners, tool plugins, etc)

I generally don't get great results from LLM code because most of my work is in C++ (which I'm guessing is underrepresented in the training data?), but when I point it towards some well-worn javascript thing I've had real successes! Most recent example is this little chrome plugin I had it whip up in one shot (https://chromewebstore.google.com/detail/favicon-tab-grouper...) because I couldn't find the exact functionality I needed in other plugins.

Works perfectly for my needs, took less than five minutes to spin up, and I use it all the time. If you're looking to get started with vibecoding stuff, try making plugins that provide niche functionality for your hyper-specific workflows.

These time-to-complete estimates seem reallyyyyyy aggressive to me. I dunno maybe I'm just the slowest programmer in the world.

Isn't this just a form of next token prediction? i.e. you'll keep your options open for a potential rhyme if you select words that have many associated rhyming pairs, and you'll further keep your options open if you focus on broad topics over niche
