deckar01on µcad: New open source programming language that can generate 2D sketches and 3D

This does not seem to have a constraint solver or any documented plans to integrate one. I love math, but I don’t enjoy maintaining walls of trig to make trivial constraints parametric.

Stubbed and 6 minutes later updated with this wall of text. Seems like the timing of an LLM. That said, I would watch this movie.

deckar01on Avería: The Average Font (2011)

Try the GWF Serif variant. It has more satisfying symmetry. Other than 4.

deckar01on US startup Substrate announces chipmaking tool that it says will rival ASML

> investments from the Central Intelligence Agency-backed nonprofit firm In-Q-Tel

The CIA has stolen trade secrets in the past and the only thing that stopped them in recent history is their own policies. The CIA has a new director that has been violating international law more openly than ever.

deckar01on Geonum – geometric number library for unlimited dimensions with O(1) complexity

It is an AI fever dream. The readme suggests all dimensions are just a single angle transformation, yet the gist says you have to stack the tuples into vectors to increase the dimensionality.

There are physics systems that are simplified by operating with phase vectors. It is not a magical constant time dimension hack.

deckar01on Raspberry Pi Pico Bit-Bangs 100 Mbit/S Ethernet

A coprocessor sounds similar to an FPGA?

deckar01on Raspberry Pi Pico Bit-Bangs 100 Mbit/S Ethernet

PIO is a set of coprocessors designed to offload signal processing. They have to be programmed. PSoC has FPGA like configuration capabilities, but rather than just logic gates it includes larger analog and digital ICs. You can route analog signal processing in and out without hitting a CPU and perform some FPGA like DSP driven by an arbitrary clock signal (also without any CPU usage).

deckar01on Project Shadowglass

I’m still waiting for Eitr.

deckar01on Roc Camera

The BoM is ~$150 MSRP. I doubt the ZKP Rube Goldberg contraption will survive a day of reverse engineering once it gets into the wild.

deckar01on Show HN: Cadence – A guitar theory app

iPhone 17 Pro Max (iOS 26.0.1)

I have reproduced the pops everywhere I am able to manually trigger notes.

I was fiddling with the guitar tones, then opened from the background when the audio broke. I tried repeating that, but no repro.

deckar01on Show HN: Cadence – A guitar theory app

If I quickly play two different notes there is a pop/crack noise. It doesn’t do this during any of the automatic sequences (likely, because it waits for the sample to stop before playing the next). (iOS)

When I went back to see if I could reproduce this outside of the Audio Challenge recap, the audio was broken. All sounds were choppy and delayed. Restarting the app the first time didn’t fix it, but switching back to the classical guitar and restarting did. I can’t seem to reproduce it now (other than the manual pop/crack).

deckar01on CamoLeak: Critical GitHub Copilot Vulnerability Leaks Private Source Code

Did the markdown link exfil get fixed?

deckar01on Chrome's New AI Features

The AI mode does seem to be free of ads. The grocery shopping use case seems ridiculous, yet is telling. What kind of compensation might they get for agents putting promoted products in your cart?

deckar01on Automatic differentiation can be incorrect

I have been using sympy while learning electron physics to automatically integrate linear charge densities. It works great symbolically, but often fails silently when the symbols are substituted with floats before integration.

deckar01on An open-source maintainer's guide to saying “no”

I see a solution to this for both sides: encourage published forks. This allows the contributor to shoulder the burden of packaging and support. If you support the patch, adopt the fork and advocate on the issue. If you find issues, help refine it in the fork’s issue tracker.

deckar01on Disrupting the DRAM roadmap with capacitor-less IGZO-DRAM technology

Decades of research into optimizing DRAM refresh efficiency suggests that you don’t understand how the world is using DRAM.

> >10^3s retention, >10^11 cycles endurance

The implication is that it can theoretically hold a value for 10^14s (~3 million years).

deckar01on Alterego: Thought to Text

You can tell it’s fake, because it’s hard wired and super low profile, yet isn’t covered in LEDs.

deckar01on I should have loved electrical engineering

Community college is the short cut. My local AAS EET program went safety -> DC -> AC -> amplifiers in 4 semesters.

deckar01on Tariff's found illegal, but will stay for now

Consider how many of these injunctions have been ignored, challenged, and gone through a separate appeals process, only to be struck down by a SCOTUS shadow docket ruling. I suspect the reasoning is that a final SCOTUS ruling will be faster by not issuing an immediate injunction.

If you squeeze the corner it turns into a gaping hole into the box.

deckar01on OpenMower – An open source lawn mower

I am imagining razor blades arranged like Vs. They don’t necessarily have to cut horizontally either. Cutting upwards would exploit the tension of the roots rather than overcoming the inertia mass of a blade of grass.

Turtle bots.

deckar01on OpenMower – An open source lawn mower

I’m not sure what your criteria is, but mine is to keep the grass alive and provide root structure for my soil.

deckar01on OpenMower – An open source lawn mower

I have been dreaming of small solar robots that quietly trim the grass all day. Static blades pulled across the grass in short bursts. RC orchestration guided by security cameras.

deckar01on The anti-abundance critique on housing is wrong

I find the term “anti-abundance left” odd. He wrote a book called “Abundance” laying out the case for deregulating zoning laws. Claiming global monopolies in aggregate seems more like a conspiracy theory. I thought the mainstream (left) opposition to deregulation was to subsidize affordable housing regardless of the cause.

deckar01on The impact of file position on code review

I have always preferred small, self-contained commits for this reason. The GUI tooling for line based commits has left me wanting though. Maybe an LLM can be trained to demux commits.

deckar01on Most ints are not floats

Here is what a 31-bit exponent 0-bit mantissa encoding looks like compared to float32:

deckar01on Most ints are not floats

You could change the scaling factor to target any bounds you want. On average the precision is equal. The mantissa just adds linear segments to a logarithmic curve.
