Breadth vs. Depth. Alg4Opt covers more topics, providing the motivation behind the algorithm, sometimes a basic derivation, and a concrete implementation. It has citations in the margin for more info. Nocedal and Wright will go more in-dept

To be clear, both are fiction, it’s just that one is fantasy and the other is set in modern reality.

Rust has a method for enforcing better memory safety. That is great for deployed applications, but can be annoying when you’re still exploring / mutating your code to figure out the right shape of things.

The article says it: “We determined that due to the persistent orientation mismatch of the towed pickup truck and tow truck combination, the Waymo AV incorrectly predicted the future motion of the towed vehicle.” It was detected, but it pre

My mom was hit by a driver when she was biking and fell with her arm in front of the wheel. The driver then decided to pull forward and drove over her arm. So humans don’t really solve that problem.

NHTSA standing general order crash rates are a mandated and publicly available data source. That’s what the study is based on.

Another very good blog overview here (not mine): https://ianthehenry.com/posts/delaunay/ I love DCELs and have been tinkering with them in my own side projects lately. Very cool data structure!

Isn’t Waymo already operating a full service in Phoenix? Haven’t heard of many issues from there.

I highly recommend the course “Computer, Enhance!” by Casey Muratori on substack for those interested in how CPUs / assembly work. You get to decode byte code, simulate instructions, learn how the stack works, etc. It is really well-pa

I recently started the new class by Casey Muratori, “computer enhance”, that teaches performance-aware programming. I also try to complete a small personal project every month and write about it.

“As of 2020, South Korea was the only country among the OECD members to have a rate below 1, giving it a shrinking population.” Being below 2 gives you a shrinking population, because men are half the pop and don’t produce children directly

You still run A*, it’s just on the nav mesh rather than on a grid.

The title is complete clickbait. It should say “no one’s short intuitive explanations of why planes stay in the air are fully correct”

A blog post in which the classic cart-pole swingup problem is solved with a hierarchical control method that breaks the problem down into a high-level search problem on top of low-level LQR controllers. Everything is derived and code is pre

Chesterson’s Fence comes to mind. If you think you have an obvious solution, you’re almost surely missing something. Killing people obviously has repercussions. Building more housing obviously has more complexities. Zoning is hard. Forcibly

the prompt wasn’t questioning why there aren’t more - it was asking where they hang out online.

My next door neighbor would scream at people passing by. I’d routinely be woken at 7am due to his swearing. Things started getting worse. He verbally threatened to kill people. He bashed in an RV parked on the road by his property, causing

This is astounding! I’ve looked into papers on this topic before and found them indescipherable. I love the clean visualizations, the implementations, and the clear progression.

The Chinese room argument is claimed to show how consciousness cannot be based on computation. I totally disagree - it merely shows that as an external observer we cannot verify consciousness.

I absolutely love doing this. I often write in LaTeX, where new lines don’t effect the typeset output. It is so much easier to see git diffs, comment sentences out, move sentences, identify a sentence by its line number, etc. as well.

“Proofs from the Book” is a great (and IMO fun) book. The 3Blue1Brown YouTube channel is amazing as well.

An HTM layer is one feedforward layer in a Heirarchical Temporal Memory network. See for example https://arxiv.org/abs/1511.00083 which trains one-layer HTM models. See for example https://timallanwheeler.co

An HTM layer requires far more parameters than a traditional deep neural network, on the order of gigabytes for one or two basic HTM layers. A cortical column is going to have many such layers, and a 1000-brains model will have many (thousa

This is an area that a lot of people are probably interested in. We still don't really have practical robots, self-driving cars, and personal assistants, and some sort of general context-sensitive learning intelligence breakthrough is
