hspeiser··on Introducing System One Models and Jev
this might finally be smart enough and fast enough for jarvis. hard to feel like iron man when your assistant takes 8 seconds to decide to pause your music
hspeiser··on ChatGPT Images 2.5
the clothing examples are super odd because its not actually useable. the clothes will not look like that on you, it just fits them to your body.
hspeiser··on I'm a seeing-eye dog for a computer
I completely understand this. I’ve worked on robot hands and 5.6/Fable 5 were practically useless at helping me debug anything visually.

What I have found super useful actually is having models make a interactive 3d viewer in which I use move / highlight / paint (soft body painting directly onto the geometry for issues and different colors mean different failures). This gives a much better way to communicate the physical relationships and positions that are hard to get across in a labeled screenshot.

Its for sure still a lot of manual work so the "seeing-eye dog" description definitely holds. But I have found that after a couple of examples with the extra context the model gets much better at handling the problem and becomes useful.

hspeiser··on Mario Meets Pareto
Ive been played. Me and my brother used to play this all the time. He would always beat me and whenever I would win it would be a momentous occasion. Turns out his build was directly on the pareto frontier and mine was not even close. Damn you brother. Hes totally screwed next time we play
hspeiser··on I built a tool that matches songs to driving speed
Have you ever walked or run to the beat of a song, or tapped along without even thinking about it?

This morning I was driving on the highway listening to Paranoid by Black Sabbath, cruising around 75 mph, and I noticed the beat of the song lined up perfectly with the lane markings passing by my car.

I started wondering if I could do that intentionally, so I skipped through a bunch of songs trying to match the beat to the lines (I learned pretty quickly that I couldn’t).

Then I wondered if this would work on any highway, and sure enough, there’s actually a standard for the length and spacing of lane markings in the US.

Anyway, I wanted to cheat, so I built this.

You type in a song, and it tells you what speed to drive so the beat lines up with the lane markings.

It uses the Deezer API to get a song’s BPM. If there’s no BPM available, it takes a sample from the audio preview and tries to estimate the BPM using PercivalBpmEstimator. I tried my best to minimize errors, but every once in a while the BPM of a song is still a little off.

Enjoy cruising to the beat, everyone!

These are so funny I love the style
hspeiser··on Failing grades soar with AI usage, dwindling math skills in Berkeley CS classes
Pretty ironic that these kids are failing a non major requirement called "the beauty and joy of computer science"
hspeiser··on Hacker News front page as a site
The inception effect here is hilarious. Watching this get its own front page while the subtitle lags behind with the previous top posts is weirdly funny.
hspeiser··on GenCAD
Took isometric screenshots of drawings from very simple parts I made in onshape and imported them. They were black and white and very clear.
hspeiser··on Click (2016)
thats pretty creepy. I find it unnerving that they know exactly where my cursor is.
hspeiser··on GenCAD
I spent a few hours trying to get this to work, and I couldn’t get it to produce usable results on anything except the training data, even with very simple drawings.

I noticed in the GitHub that they mention it is only around 60% reliable even on their own training data, but the image shown on the front page feels pretty misleading. I made 10 images that were very similar in complexity to the examples shown, and even after running it around 50 times on each image, not a single one worked correctly. In the rare cases where it produced something, the output was completely wrong.

This seems pretty misleading in its current state and definitely needs more work.

hspeiser··on The Hunt for Dark Breakfast
What about french toast? I feel like there is a lot of egg in it, might place it near the bottom of the abyss.
