Cool! Constraint propagation from SICP is a great reference here: https://sicp.sourceacademy.org/chapters/3.3.5.html

I am so into optimizing fast polynomial multiplication I assure you there is nothing that will demoralize me from creating a slightly more optimized version.

The phenomenon described in movies has a name called “Idiot Plot” ( https://en.wikipedia.org/wiki/Idiot_plot ) an older term which Roger Ebert popularized. Feels missing from blogpost.

What if the goal of writing about how “AI is bad for the environment” (because of the energy and water it uses) is to identify gullible people and on-ramp them into a lifetime of media manipulation?

it’s all running inside a Proxmox VM with IOMMU and GPU passthrough. It’s as safe as doing the same on any cloud system. Also the machine is well north of 100K when you include the RF ADCs and DACs in there that run a radar. Worst case, I h

I also use Claude Code to install CUDA and PyTorch and HuggingFace models on my quad A100 machine. Shouldn't feel like debugging a 2000s Linux driver. HuggingFace has incredible reach but poor UX, and PyTorch installs remain fragile. T

It is not about whether some team somewhere is dabbling in math, it’s about institutional emphasis. When serious math work exists, it tends to be checked before being broadcast. The fact that this didn’t happen suggests that genuine mathema

Not quite. Leakage current in CMOS circuits became the dominant source of power consumption around the 90 nm and 65 nm nodes, long before quantum tunneling was a major factor, and often exceeded dynamic switching power. This led to the intr

The people involved are very smart and must know that AI doing novel math is a canary for AGI. A serious effort around solving open problems would not fuck up this kind of announcement.

The sad truth about this incident is that it reveals that OpenAI does not have a serious effort to actually work on unsolved math problems.

I like these benchmarks and the videos are funny! Consider examples using building tools like screwing in a drywall screw, or hammering a nail, using a paint roller, caulking a sink, minor plumbing repair with a torch and solder. These diff

If you are doing polynomial multiplication and want exact integer convolution then you can’t leave the precision of your FFT up to chance so the alternative to an FFT over complex roots of unity is to use something called a Number Theoretic

For the curious: the process of discovering the logic and route timings for an FPGA device is to use ring oscillators (three series inverters) and compare counters against a known clock. Place the inverters all over to test every LUT, and u

Just putting this up as a reference the next time this comes up on HN. The study data shows that the median task is 1.5hrs and the 15 minutes that developers think they saved was actually more than that many minutes less researching, testi

That METR study gets a lot of traction for its headline; and I doubt many people read the whole thing—it was long—but the data showed a 50% speed up for the one dev with the most experience with Cursor/AI, suggesting a learning curve

This isn’t the full story though, like I (professionally, as a consultant) analyzed GOPs/$ and /Watt for big multi chip GPU or FPGA systems from 2006-2011. Xilinx routinely had more I/O (SerDes, 100/200/400G MACs on

You can tell the veteran status of FPGA devs by the quality of their rants about the tools. The big FPGA companies have no quality metrics for developer experience. You should be able to make an LED blink within a minute of powering up a bo

The blogosphere (am I dating myself?) keeps bringing up the METR study ( https://metr.org/blog/2025-07-10-early-2025-ai-experienced-o... ) without really understanding the result. The guy with experience had a huge boost
