No, about 33% is the theoretical limit for any single-junction cell for *a single wavelength*. We also have silicon and carbon pillar nanotech that allows capture of almost all wavelengths, it's been here in /. before. Single-junction cells will get far more efficient as we can harness wider bandgap ranges.

" The bus is more often the bottleneck than anything connected to it in modern computing systems."

Not even close. Quite often it's the underlying architecture itself causing the bottlenecks.

Example, Intel's latest and greatest Xeons FUCKING SUCK. Why? Because their internal architecture to deliver data across cores is gimped beyond belief. You can run 2 CPU x 4 GPU, 4 CPU x 2 GPU, but you can't do 4 CPU x 4 GPU. Meanwhile, I've got far older AMD systems that run 4 CPU x 4 GPU without a problem.

"I interviewed with 2 companies last year that were very up front about my being mid-40's was a problem. In one company, 5 of the 7 people I talked to brought it up and a couple clearly had problems with it. The recruiter that flew me out congratulated me on putting up with it - what an asshat."

That's entirely illegal age discrimination. Age is not a legal bona-fide occupational qualifier for IT work.

Comment Re: have you tried telegram messenger? (Score 1) 114

I have it installed on both iPhone and desktop. There is no video.

Try reading their own FAQ:

"Q: Can I make calls or video calls via Telegram?

We specialize in sending messages, large media and files — and we do this better than anyone out there.

We may enable voice calls if we see significant demand in the future. The technology necessary for encrypted calls has indeed been created in our R&D dungeons.

But for now we see many things that could still be revolutionized in messaging. And messaging is obviously trending at the moment, so our focus remains in that area for now."

No, they do not do video.

"I'm actually doing these kinds of things, right now, with those "high-power LEDs" of yours."

I guarantee you are NOT working with anything CLOSE to the power range I'm working on. Even then - you aren't soldering a lead to the thermal pad of a 1W LED and getting it to operate at FULL DRIVE for more than a few seconds before it burns itself out. You've just totally screwed the thermal profile of the LED. There's a reason it has a huge 5x7mm pad and not a tiny-ass leg like your cheap-ass 5mm 'High power' LEDs.

Go mount a tiny leg to an MK-R and drive it full power, and try using that tiny leg for a heat transfer mechanism.

You're so full of shit.

"Do you think Dell builds their own boards? They don't."

As a former HP and Dell engineer, uh, yes, they do.

They build the original design and then hand that off to a company for mass production.

Google does NOTHING OF THE SORT. They used pre-built designs that fit their particular form factor and desired specs.

"That's assuming that a "storage capacitor" and a traditional capacitor are the same thing. I didn't."

You should, because a capacitor is storage/filtering and nothing else, period. Exactly like a battery, except it has a far, far higher rate of charge and discharge, and can undergo many, many, many magnitudes of order higher charge/discharge cycles versus a battery.

"Heck, there are already batteries that are more than just simple batteries. For example, ones with temperature sensors for charge control."

That's more of a safety requirement than a feature due to the particular characteristics of the underlying battery chemistry.

What's the point of that? It's large, ugly as sin, and the concept only works assuming low use anyway. It's also not going to work as intended if you park it in a garage, inside parking spot, or in the shade.

I wonder if it's even practical in ideal conditions, because a car parked in the sun gets hot as hell, and batteries don't like that much.

It's much better to put those panels on your roof instead. That way you can go with cheaper and less efficient panels because there's less need to squeeze all the possible power in the small amount of room available, they'll be unobstructed as much as possible, collecting power at all times when there's any to collect, and it can be used for things besides the car.

Computer Science is merely the post-Turing decline in formal systems theory.
