This was a fantastic read. I would love anything more like this to share with students, but either somewhat simpler or to the same level but including more basic concepts as well. Or something that goes into more detail on the practical tut

Lecture videos appear to be private. They've had 5 class sessions so far but no assignments are viewable - maybe some will show up soon or perhaps those will be private as well. There's a Piazza signup but it's only accessibl

There are things I would build many of if they cost $2 instead of $20. Say a medium-resolution 3D volumetric mapping of temperature and humidity in my house becomes reasonable at $2/node, but not at $20/node. I think scale still a

Came here to say the same thing. I agree, I don't think they were necessarily $1 in 2017, but it would be a very large omission today. It may be worth remaking an article like this today...I wouldn't mind helping someone out with

Something like 45% of the world's people don't have internet access right now, so that number would be billions, rather than millions. Also, Starlink doesn't have to be too costly for them. The constellation's operating

Evan Miller argues that it's probably simplest to stick with thumbsup/thumbsdown, but not to fall into the trap of using dead-simple analysis methods like "Score = (Positive ratings) − (Negative ratings)". Instead he arg

This is super cool to see a quick overview of. I have a few hobby projects ongoing using C on Espressif chips. I wanted to use Rust for some of them instead. While I'm very much looking forward to ESP32 / ESP8266 support for Rust[

ClarisWorks generally got UI features for new OS-supported features very early relative to other default apps. Despite being ostenibly a word processor, ClarisWorks was the first tool I was able to use for ripping songs from CD's.

You brought up Daytona. Florida's an interesting case where discussions of plate tectonics may be off the mark. Seems like it was formed mainly by deposition of seashells, shellfish, corals and sand and clay over the past 30 million ye
