As opposed to the Star Trek 2009 which had Nimoy alone, and in a bit part.

screw mad max, lets cal it what it is, Mad charlez, the rise of estrogen in a post apoplectic world..

Oh, you're one of those guys. OK. Thanks for clarifying; that explains a lot. I'm not a feminist (except in the "women are equal, we should treat them like people" sense), but you'd have to be a major MRA to have any problems with Fury Road. Oh, there was a strong woman character and Max had a peer and an equal. Shock! Horror! [insert eye roll here] If you can't enjoy Furiosa being as fierce of a survivor as Max, then there's something broken in you.

When I installed solar panels, I did not connect the system to the grid because I was primarily after fault tolerance rather than lower costs or "greenness". Sine wave inverters (necessary to run motors, like in refrigerators) are expensive, and it made more sense to run a parallel 12 volt circuit to run things that are ok with 12 volts, than try to run an entire 110 - oriented house on 12 volts. Most non-motor appliances step 110 down to a low DC voltage anyway, and it seems wasteful to me to step up 12 DC to 110 AC and then back to 5 or 6 volts DC at the appliance end.

It turns out that there are a plethora of 12 volt choices at the local RV store. Even 12 volt CFLs. Any portable appliance can be run off a car adapter, and even appliances that aren't meant to be portable can be run off 12 volts with careful selection of the right adapter. (Voltage, noise, and current are important.)

Who knows, maybe some day we'll see major appliances with built-in inverters designed to plug right into a 12 volt circuit. Or maybe appliances with DC motors? Not really my area.

The only thing that worries me a little is the current requirements. Approx 1/10 the voltage, it seems to me, would mean 10X the nominal current for the same power, and I don't see running car-starter-cable gauge wire through the house. I'll have to do some measurements. For CFLs and electronics, it hasn't been an issue so far.

"News for nerds." It's right up there in the tagline. Mad Max is near the top of the geek movie franchise pantheon, probably just below Star Wars and Indiana Jones. This isn't a new Fast & Furious, it's a new freaking Mad Max. You know, that thing that got a lot of us into postapocalyptic / dystopian sci-fi flicks. If this doesn't count as cultural news for nerds, I can't imagine a lot else that would.

Microsoft powered phones don't exist in the real world. I have yet to see one. They are apocryphal.

I am shocked that in the hours since you wrote this comment, no Microsofties have showed up to tell us how wonderful their Windows Phone is. I literally only ever see those comments on Slashdot, but normally they are as reliable as the sunrise.

Not true, a jailbroken iOS device is essentially a small BSD box.

Oh? So you have the source code? Snicker snort.

A jailbroken Android device, on the other hand, really is a small Linux box. You can trivially install a more complete userland on most interesting phones. You can install an X server. You can get the sources to everything but the Google Play stuff, and you can use the phone without that stuff. In theory you should even be able to throw away the GUI and all the apps from Android and switch to Wayland someday, at least on relatively modern phones whose graphics drivers will be usable by Wayland.

Now, tell us again how much your iOS phone is like a computer, please. We're fascinated.

Obviously, our technology is not at the point where such a thing could be created. It may very well require molecules to be assembled atom-by-atom.

That doesn't actually preclude our doing it, although we won't be able to do it with a robot arm any time soon. (Would love to be wrong.) It might be possible to do it with biotech, though.

If you're using somewhere near the inverter's peak output, then you can get as much as 90% efficiency. Inverters are getting smaller all the time, which makes it more feasible to gang modules instead of using monolithic units which will provide very low conversion efficiency for low outputs.

It's still unfortunate to leave 10% on the table. But a lot of DC-DC power supplies are also not very efficient. Best-case, they are only around 95% efficient, and you can easily lose another 10-15% if you execute them poorly. So yes, optimally they have half the peak loss, and even bad ones are likely to be better, but we can make better inverters and we will as the demand increases.

I agree with your post mostly, but what exactly constitutes a "power user"?

Well, we could argue about that all day, but I argue that it doesn't really matter: no matter what it means, they're more likely to use Android. If it just means they are going to want to use a broad variety of apps from disparate sources, that's Android. If it means they want to customize their phone as much as possible, even just bling-bling style, that's Android. If it means they want to tinker with the internals, obviously that is Android. If they care about security and controlling what apps can do on their phone, that's also Android, albeit one of the cooked-down versions and without Google services — but you can do that if you want to.

You could argue that any of these desires makes you a "power user", but clearly any of them will also lead you to Android. If you took some of them to extremes you might end up someplace else, but it wouldn't be iOS or Windows Phone.

Linux had 1 crappy pay-for version of CDE because some schlep company ended up buying copyrights to extort money from people.

I don't even remember there being a pay-for version of CDE for Linux. I'm not saying it didn't happen. I just remember you could buy a Motif tarball from Metrolink that would get you Motif and mwm, not like you would ever use mwm when you had fvwm. And then later you could buy Caldera Network Desktop, which came with Metrolink Motif. You could also buy AccelX, which got you a substantially faster X server back in those days, with meaningful support for your video card's 2d acceleration features... something that XFree eventually achieved, of course. Apparently you can build CDE for Linux these days, but I haven't tried. (why...)

Doesn't the Linux kernel group hold a very similar stance in that you cannot use the kernels internal APIs without breaching copyright and thus falling under the GPL as a derivative work?

Not really. TL;DR: Linus doesn't say so, and he holds the trademark, so he gets to decide what makes "Linux(tm)".
