I'd also REALLY like to see where you are pulling your reliability numbers from.

There are publicly available uptime tracking web sites.... Always dominating the top of those list is OpenVMS, thanks to its (ancient) built-in clustering technology.

Linux isn't even old enough to compete...

if you're running one the million- or billion-dollar companies [...] actually do anything, you're talking mainframes one way or another (call them a "cloud" if you must).

A cloud is usually a cluster a commodity computers, not a mainframe. A cluster can easily outperform a mainframe at lower cost, while having much higher reliability.

Certainly, the Fortune 1000 companies used-to run lots of mainframes, and they've got plenty running legacy apps, but today, they're just as interested in clusters of cheap PCs as the little guys. Google, Facebook, Amazon, et al, aren't interested in mainframes at all.

What is happening now with gay rights is what happened with racism in the 60's.

That's utter bullshit. I'm sure blacks in the south would have loved if the only problem they had in the world was not being able to get the tax breaks and entitlements that come from a state recognized marriage.

Is that was passes for oppression, these days? I'm inclined to go lynch 10,000 homosexuals, just so people would get to see what real discrimination looks like...

Such a first-world problem, that a group not getting the tax-breaks and incentives (that were always meant as incentives for child-bearing families) passes for discrimination these days.

"I'm not accepting any patches until you fix your bugs" is hardly suspending someone,

Only because that's an inaccurate misquote. Let's try the real thing:

"I will *not* be merging any code from Kay into the kernel until this constant pattern is fixed. This has been going on for *years*, and doesn't seem to be getting any better."

That's not a "fix this bug first" message... That's a much more general and sweeping "you suck, so you're fired," message.

Of course both Kay and Linus reserve the right to change their minds and play nice together in the near future, but that doesn't sound likely.

Comment Re:Timers and motion sensors (Score 1) 176

Even with LED bulbs being relatively efficient I see no point in leaving them turned on unnecessarily.

No reason for it, but there's the question of the cost of devices to automatically shut them off...

For your pantry/storage closet, I'd probably use an old $1 refrigerator door switch, or maybe a magnetic alarm switch like so:

Comment Re:Timers and motion sensors (Score 1) 176

I put a timer switch on a closet light my wife and I tend to forget to turn off. Automatically shuts off after 5 minutes as it is just a pantry/storage closet. I've got another spot with motion sensors. I have to turn the lights on but then a motion sensor turns them off if there is no motion in the room for X number of minutes. Good for locations like kitchens.

I hope those devices were cheap. With the efficiency (and low cost) of LEDs, it might take YEARS of energy usage to pay off those (also reasonably inexpensive) timers and motion sensors:

They said CFL would last 7 years. Good luck having one last more than 2 years if it's used regularly. I replace my outside CFLs yearly.

CFLs are terrible for outdoor (cold location) use, and they're lousy anywhere they'll be turned on/off frequently. CFLs also have issues with failure if not mounted in the proper orientation they were designed for, or used in small fixtures that get hot.

LEDs have no such problems, and furthermore, the $10 Cree 60W equivalents come with a 10-year warranty from the manufacturer.

Comment Re:Voltage != Power (Score 1) 208

5v is so your keyboard doesn't need a voltage regulator [...] 100mA at 20v to 3.3v inside a keyboard? A nice 1.7 watts of heat converting your keyboard to a gentle hand warmer.

You might have noticed that USB has more than two wires... It would be absolutely trivial to add one more pin that outputs 12V.

Higher voltages, like 20V, would be trickier, because computer PSUs are standardized on providing lots of amps on the 5V and 12V rails, and only very, very little at other voltages. PSUs do 24VDC, but you can't draw more than a quarter amp before something pops.
