Generating energy from the difference between extremely hot and slightly hot is cheap and efficient using turbines. Going from slightly hot to cold, as in the case of geothermal and capturing residual heat in the stack of a natural gas plan

Blending the colors in Photoshop manually seems very tedious. The open source Enblend/Enfuse, which ships as part of the open source panorama stitching software Hugin, does it automatically and seamlessly. http://enblend.sou

United Wholesale Mortgage was the subject of some reddit /r/wallstreetbets pumping earlier this year which then later fizzled out. I guess they are trying to piggyback off crypto hype to keep up their meme stonk status.

Ah yes, OpenGL's error reporting is notoriously bad. If you forget to call disable on a vertex attribute you might just get a random error 1282 (invalid operation) somewhere down the line in a totally irrelevant part of the code, lol.

Real depth cameras perform better and cost far less than the $1500 GPU that you're going to need to run the monocular depth network. Monocular depth still struggles to generalize to environments that are even slightly different from th

> That said, if only Sony is making these, they'll just keep the prices the same to rake in more profits. You seem to be suggesting that Sony is price gouging or something when in fact they are probably the most innovative camera co

Lidar can be embedded in the headlights or on the rear view mirror; there is no need for ugly protrusions.

GPL allows you to use and distribute open-source code as long as you follow certain conditions like open sourcing derivatives under the GPL. Since Chessbase has not done that, Stockfish devs are no longer allowing Chessbase to use their cod

As someone who has taken the Shinkansen in Japan, the seats and legroom are vastly bigger and more comfortable than on airplanes. Moreover, the view is nice and normal air pressure is nice too.

I have a Valve Index VR headset. It was clearly the best on the market when I got it last year. The controllers and headset tracking are great and the video quality was a notch above the competition (though recent newer headsets have closed

For NURBS modelling there is OpenNURBS [1], made by the guys who made Rhinoceros 3D, an excellent NURBS 3D modelling program. However, although Rhino is available on Windows and macOS, it is not available on Linux and the authors seem prett

I think public hiring challenges like this are less of a barrier that filters out candidates, and more of an attractor that increases the number of applicants by "nerd sniping" people.

A lot of this is due to legacy software decisions. To deal with old slow drives, people use expensive compression algorithms which take the CPU longer to decompress than reading the uncompressed data itself. Also, if we were to directly cop

Ironically the CIA themselves is very good at writing propaganda with a neutral and objective tone. For example Radio Free Asia is generally considered neutral and objective despite its ties to the CIA.

The Nikon F3 he used has automatic metering so I don't think he had to do any ISO-related math. And manual focus with its great split prism viewfinder isn't that hard, although obviously more challenging than autofocus.
