deckar01··on Weave: Merging based on language structure and not lines
There was some discussion on that topic when they self-promoted this 3 months ago: https://news.ycombinator.com/item?id=47242929
deckar01··on Ford CEO's Right to Repair Comment Should Make Every Car Owner Uncomfortable
From what I have read most of the recent EV companies failed due to investor shenanigans. Fisker and Coda made it to production promising ~$30-40k models, but only really delivered ~$50-70k models before they folded. Slate is posting videos of an operational factory building the model they advertised and seem confident it will be under $30k.

Slate is outsourcing service operations to any shop that wants to pay $50 to get certified.

deckar01··on Show HN: Resonate – Low-latency, high-resolution spectral analysis
I don’t like the bins drifting from so far away so slowly. There needs to be repulsive force that prevents the bins from colliding.

It would be interesting if the resonators could adaptively model timbre to factor out harmonics while still handling unique timbre at each frequency. That could produce a pitch diagram color coded by instrument.

Edit: I bet you could fork a resonator and run over the window it just finished in reverse to correct the drift.

deckar01··on LLMs are eroding my software engineering career and I don't know what to do
Businesses like a record of reliability, so devs going solo with AI is going to be a hard sell. I think we will know that AI is actually good enough when these AI providers start absorbing project management companies and hiring contractors to use their product instead of selling subscriptions.

It also says it is supposed to be available in their own Edge Gallery app and it’s not there (on iOS).

If only they had launched that yesterday I might have avoided Copilot auto model selection using a 9x model, quietly burning my monthly quota in a single afternoon.

Prologium is depositing thin film solid state batteries onto flexible ceramic insulators. They have some demos of single cells that appear to be thinner than 1mm continuing to operate after bending in half.

But it jumps around and flickers pretty bad. Chrome’s own demos in the docs don’t work at all.

Edit: Their reference works and has some really nice demos. Must be an iframe problem. https://scroll-driven-animations.style/#demos

deckar01··on Angry devs vow to flee GitHub Copilot as metered billing takes hold
Not only did they switch to token billing and increase the multipliers, they started auto selecting 6x and 9x models more often than before. The UX is such that you don’t find out what model it chose until after the request is complete.
deckar01··on SF startup is testing robots in Airbnbs, and trashing them, lawsuit claims

This sounds a lot like criminal invasion of privacy.

Edit: What are you downvoting? You can’t secretly watch Airbnb guests through a window you rented to them for the same reason you can’t put spy cameras in their bathroom.

It is a blind auction with a $50k minimum bid.

deckar01··on I 3D Printed Origami [video]
I wonder how their slicer is handling the infill angles. I suspect the bridge detection is only kicking in on the top layer, which ensures the infill angle is perpendicular to the gap. The bottom layer is going to follow a global angle and eventually run parallel to a hinge as the design gets complex (hence a later design failing and requiring thick hinges).

Painting infill angles would be tedious. I bet with concentric infill and some clever zero width cuts you could make all of the hinges perfectly perpendicular.

deckar01··on 3D Gaussian Splatting in a Weekend
After seeing the fixed 3rd order spherical harmonics I was curious how that might be optimized. DropAnSH-GS (Feb 2026) drops out high order SH coefficients to force low frequency color into low order coefficients (3.4. Spherical Harmonics Dropout). They conclude that high order coefficients can be discarded to trade off speed/size for detail. They don’t seem to have considered encoding as sparse coefficients post training to discard all near zero coefficients.

I don’t remember it being covered in any of my government classes, and I had not considered alternatives to electoral representation until it started being so openly corrupted. Sortition USA looks interesting.

> Most people don't really seem to care about data collection when it comes to AI usage.

That assumes you intended to use AI. People are going to accidentally upload random private content to google.

Wiggling the mouse is what people do involuntarily when the computer isn’t working right. They are setting themselves up for Gemini to be the uninvited Clippy, except this will send everything you are working on to Google to harvest data from.

I have a suspicion the room reverb of anything other than that guy’s lab is enough to break it.
deckar01··on NPR finds "no sign" of Polymarket at its Panama HQ address
> there was no sign of Polymarket, nor the entity it does business as

The law firm at that address was not their registered agent. Their ToS mandated arbitration with an entity that doesn’t exist.

deckar01··on 1966 Ford Mustang Converted into a Tesla with Working 'Full Self-Driving'
That Vagabond Builds video... They edited it, but left in a claim it had a frunk. The commentary felt like engagement optimized stream of consciousness blather. They cut out shots of the car being moved and never showed it being driven.
deckar01··on Redistricting and the Supreme Court have cut voters out of US House races
Mainly participation. Voter participation is already very low. It would be interesting if voting was more like jury duty and a random sample of the population was selected to vote per issue. That way there are no termed representatives to corrupt and participation is always significant and uniform.
deckar01··on Minimal Fab Promoting Organization
I am surprised US prototyping companies don’t have more regional facilities. It costs ~10x more to have an Oklahoma machine shop cut a sheet metal pattern than to get it shipped from California. The difference seems to just be letting the customer make mistakes rather than requiring manual design verification. I probably would not have purchased a CNC machine if they offered 2 day shipping for <10% of the part cost.

State ballot measures allow passing laws directly by citizen vote. Peaceful change is possible.

I’m ready for a modern form of representation that isn’t constrained by how many people an old building can hold. I wish small groups could have a representative with a proportionally small fraction of voting power.
deckar01··on Welcome to Hell Developer
I think about troubleshooting like OBST with test cost. Systems are a linear chain of points of failure. The more knowledge you have about how hard components are to test and which components break more often, the easier it is to choose the tests that optimize your time.

They let you write python programs as long as it’s from memory though. I wonder what the code golf looks like for a rudimentary python CAS. If you could evaluate the equation without needing to parse it, I bet you could get a lot of mileage out of a black box gradient decent routine. The analog circuit solver I wrote for my nSpire (without CAS) was ~11kB. https://github.com/deckar01/pylacc
deckar01··on Warp is now open-source
> Why now

I am skeptical that they decided human input is their bottleneck just as the cost per token spiked from some AI providers. I see this as a way to reduce their compute spend (offloaded to the community), but I doubt they are going to give up any creative control, so their employee review bottleneck probably won’t change.

deckar01··on Coffee with a splash of physics: how to make the most out of your brew
There is another solution: Get a machine with flow control and a pressure gauge on the group head. You can saturate the puck at low pressure to avoid dry pockets, then ramp the flow rate up until the group head pressure peaks. If the pressure starts to drop you can increase the flow to maintain the group head pressure.

As for the 6 bar course grind theory: You may maximize the extraction of soluble coffee mass, but the concentration will be lower. It does not take very much extra water to ruin the taste and texture of a latte.
