percentcer··on Show HN: Warsaw in voxels – An interactive 3D map of the city centre
This is neat but the FPS controls are very strange, I'd recommend changing the A/D movement to be a 'strafe' (lateral movement, no rotation) and reversing the mouse look directions (i.e. dragging right should rotate the camera to the right instead of dragging the screen like it might in figma)
percentcer··on Microsoft killed FoxPro in 2007. Anyway, here's FoxPro revived
"The IDE, on Visual FoxPro's own sample projects. Every picture is a real session." starting to have involuntary revulsive twitches from Claude prose

opsec is when you summarize the contents of a document into a word and then use that word as the encryption key for that same document

percentcer··on iPhone Duo
Despite what the marketing material would have you believe you can always see the fold. Even when it's fully open. Folding screens have been a solution in search of problem for like a decade now
percentcer··on OpenAI's new reasoning technique alarms AI safety experts
Relying on CoT (and, similarly, asking the model to explain its actions) for analysis has always seemed pretty silly (naive?) to me, but maybe I'm missing something. Why do are we so committed to preserving it? And do non-textual models provide some similar form of tracing?
percentcer··on 2004 RuneScape fit a multiplayer RPG into 56k dial-up
I don't understand how RuneScape managed to get the traction it did. 2004 was the same year World of Warcraft came out!

This whole article is just (barely) rephrasing a few popular twitter threads from the past week.

percentcer··on Riding the D in Los Angeles: city hopes new subway stations will be game changer
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.
percentcer··on Is my blue your blue? (2024)
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.

percentcer··on Recreating Epstein PDFs from raw encoded attachments
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.
percentcer··on Here is the 15 sec coding test I used to instantly filter out most applicants
Why wouldn't a qualified developer just run the code? Takes two seconds instead of ... whatever you're going for here.
percentcer··on HTML as an Accessible Format for Papers (2023)
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
percentcer··on High-performance 2D graphics rendering on the CPU using sparse strips [pdf]
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)

percentcer··on Matrices can be your friends (2002)
The only thing that ever made this click for me was that the columns can be interpreted as the values for the new, post-transform basis vectors
percentcer··on Survey: a third of senior developers say over half their code is AI-generated

percentcer··on A guide to Gen AI / LLM vibecoding for expert programmers
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.

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
