Comment Everybody Hates Documentation (Score 5, Insightful) 85

It usually goes to the lowest-ranking person on the team or the one everyone's trying to keep away from actual coding.

It remains worth the effort to write a novel around your code - not just what you did and why you did certain things a certain way, but the meta-reasons. The more those who come after you understand, the easier it is for them to figure out and maintain your code. It also tends to focus you more on writing good code, because you don't want to document, "Well, it looked good enough and didn't immediately produce errors and I'm tired of this and want to move on".

AI code? Well, AI should be very good at generating plain-language documentation of 'what', but it is absolutely going to fail at 'why'.

Start with a ducted horizontal wind turbine. If you imagine a bunch of salad bowls stacked with spacers and you get the idea of what it would look like from the outside.

The ducts collect air from any direction and drive it down, through the turbine, and out the bottom. Water doesn't turn corners quiet as easily as air, so you can use the ducts to separate out the majority of liquid and drain it away from your turbine.

Then you and an armored shell of horizontal bands that can be moved up and down to reduce or enlarge the duct input slot area. Instead of having to worry about wind load and braking at the turbine, you control dangerous wind load at the intake.

There's your monsoon-resistant wind turbine.

1) Not tied to frequent fuel deliveries

2) Does not require much that humans don't already need - sun and air. (Variability will affect your power storage needs)

3) It can be deployed almost anywhere, and even be portable.

The main issue is energy density - if you want to drive hundreds of kilometers a day, run your AC all summer and heat all winter, etc., you're going to need a lot of land dedicated to power collection.

I imagine there are a lot of places in a continent like Africa where people might be happy to get by on what solar can give them in return for not having to worry about burning oil or anything else to get electricity.

Interesting, you're right that the Steam Deck is actually heavier, I just weighed both and TBH the Switch 2 still feels heavier to me, maybe because it's just denser, but that's apparently purely illusory. My measurement results don't match the posted values (I get 550g for the Switch 2 and 696g for the Steam Deck LCD) but those numbers are probably thrown off because I've put aftermarket screen protectors on both of them, as well as a popular brand aftermarket SSD upgrade in the Steam Deck.

Submission + - Researchers identify people through ordinary Wi-Fi with 99 percent-accuracy (tomshardware.com)

Baron_Yam writes: Security researchers at the Karlsruhe Institute of Technology (KIT) in Germany have published a paper demonstrating that unencrypted beamforming data broadcast by Wi-Fi devices during normal operation can be used to identify individuals walking through a room with 99.5% accuracy, regardless of whether the individuals are carrying Wi-Fi devices. The tactic leverages the router's beamforming tech to identify individuals with up to 99.5% accuracy, and it works with existing routers, too.

The system, called BFId, requires no specialized hardware, no access to the target Wi-Fi network, and works even if the person being tracked isn't carrying a wireless device. The team tested the attack on 197 participants, the largest dataset ever used in Wi-Fi-based identification works, and plans to present its findings at the ACM Conference on Computer and Communications Security (CCS) in Taipei.

See GitHub — https://github.com/ruvnet/RuVi... — for your own personal implementation requiring a couple of APs and a couple of ESP32 nodes. You can get full-home per-zone motion and occupancy detection fairly reliably, with the potential for pose detection and in optimal areas even respiration rate. With the right hardware and configuration, you can theoretically get heart rate too.
