Cringe-worthy on multiple levels. Instead of monitoring LED temp, he monitored cooling water temp to test his cooling system. Of course, you might consider putting his fingers on the heatsink as monitoring, lol. On a less critical note, he did follow British plumbing standards ...

"the more cars you add, the more road you need, the more spaced out everything gets, ..."

Disregards the promise of Connected and Autonomous Vehicle (CAV) technology.

There has never been a better magician in our field than Steve Jobs. RIP.

Most efficient answer to "why the hell should Apple prevent someone from ...":

Control.

You're thinking about the energy conversion efficiency. They are claiming 130% quantum efficiency, i.e. the efficiency at which a photon can produce a free electron.

I worked on a construction crew one summer in 1966 building concrete structures for a sewage treatment plant. Based on this article, not much has changed.

It was interesting to see the hierarchy of the various trades. The rodbusters (rebar workers) were cocky, fast, and had no body-fat. The carpenters that built the forms for the concrete were fat, slow, and drank vodka all day. And the laborers (e.g. me) were there mainly to entertain everyone else, lol.

Stand by for a flood of "healing light" LED lights with all sorts of health claims.

Referencing Ken Rockwell for photo advice is pretty funny. If you don't know his reputation, just look at his photos and judge for yourself. That said, his gear reviews are useful.

As for editing for brightness, contrast, ...: All digital images are edited. You either let the camera manage levels & color ("straight out of camera") or you do it.

Options will never be widely understood because math is involved, lol.

Nikon calls their line of macro lenses "Micro Nikkors".

This is a report of the results of using the drug on a compassionate-use basis. The intent of the doctors was to save lives, not provide your "stats 101 stuff".

I think it's shameful to broad-brush the entire coronavirus response as incompetent.

The PID controller explanation left out a critical concept: The controller first generates an error signal, i.e. the deviation of the input (angle in the example) from the desired input, known as the setpoint. The error is fed to the P, I, and D sections.

I was a nuclear-trained operator on a boat of the same vintage as the Thresher. I joined it in 1970 just after it had been retrofitted with SubSafe systems and better operational procedures that came directly from the loss of the Thresher.

I'm convinced that the loss of the Thresher, as tragic as it was, saved a lot of lives.

As for the documents, you need to know that Rickover classified almost everything about the nuclear program. I suspect that kind of thinking still exists and is responsible for the slow release of the document.

I will agree with you that steam or turbine power plants require continuous maintenance. I've got experience, too. :-)

But, read the article. The ship they're talking about is a short-haul transport with battery-electric propulsion. Perfect scenario to pioneer this concept. If it works, I'm betting that it would be possible to create a propulsion plant that will survive longer hauls without a crew.

WebRTC defines how the browser supports audio/video/chat endpoints. A practical video calling system needs servers to manage firewall traversal, a directory of users, and ways to admin the system.

Who's going to provide that at no cost?

This guy is going to be really sad when he learns that the dc-dc converters in most of his devices are actually dc-ac-dc converters. Evil ac must be purged.

Nice try! :-)

The movie came out years after I left the Navy. But yeah, watching it gave me that same sick feeling. The images seem to combine with memories in a way that makes me feel like I'm there. Parts of the film are unrealistic, but I won't watch it again.

I was a power plant operator on a nuclear submarine. We were shown a classified film that about the SL-1 incident as part of our training. Recalling that film still gives me chills.

A lot was learned about reactor safety as result of that disaster.
