I have no problem at all paying for content. I do have a problem paying for content by someone who then consumes my lifespan showing me crap (commercials that they're paid to put in) I have no interest in.

I'm very interested in being able to subscribe directly to production companies and other content creators that make stuff that I'm interested in.

There's another facet to this that I went through last winter. I spent about a week fighting pneumonia. After I spiked a temperature of 104(F), I went in get it checked out. After an hour or so, the GP sent me off to the emergency room to get a quick checkout with the diagnostic equipment they had there. That solidified the diagnosis of pneumonia (with some speculation that it was a legionella variant).

The interesting bit happened then, when they were deciding which antibiotic they wanted to use. They were most interested in whether there was any chance I'd acquired the bacteria in any medical setting (hospital, doctors office, clinic...). Once they'd decided that I almost certainly had acquired it in a "normal" environment, they sent me home with what they called the "grand daddy" of antibiotics for pneumonia. Levafloxacin. It seems like medical establishments are bad for you, beyond it being where all the sick people are.

By the way, the medical establishment was the Mayo Clinic.

It seems more likely that the most critical factor for a sustainable society is lack of corruption. Most of the places that seem to be hell-holes today are fundamentally corrupt, mutual back-scratching, "punish all of "those people" who don't want to play the game", collections.

The more important "who you know" is than "what you can do", the worse off the whole society is.

You use the electricity and solar heat to create methane with a Sabatier reaction, and dump the methane into the national natural gas pipeline system. The gas becomes part of the 7-30 day reserve supply and runs the gas turbine peaking plants. There is a German pilot plant that has been running since 2012 and further development is planned. has more information.

I've been using KDE for a long time. I haven't done anything with Gnome since the "Let's remove all the confusing options" movement started.

Thank you for the information, but I haven't been inspired to do any work to improve UI behavior over WAN connections. Years and years ago the worst UI behavior I saw was for a connection that was running over a 26.5 dial up connection. Strangely enough, some X apps were actually still usable. But, most weren't, and some took an hour to paint the first window. The worst ones seemed to be behaving like gimp did, causing a continuous stream of unnecessary synchronous calls to the X-Server.

I never said that there weren't other ways to do it. I just described what worked for me and how well.

I've been using X since it was X10, that includes all levels of programming from bare Xlib up. I've never written a server extension, but I have worked on the Matrox mga Linux kernel module just enough to make it work on IBM RS-6000 systems (you can grep for my last name in the kernel source if you care to check). I've also done a bit of messing about with the Doom3 sources to make it work better with Xinerama on a multi-screen setup.

By the way, I've still haven't seen a window layout object that works as well as the Motif Form Widget.

X-Windows can be doing either remote drawing command or sending blobs of pixels, it's all within the protocol. So, the only way to tell is to get something like xscope into the picture and see how the application is handling the data. One of the better ways to handle general window drawing (not pictures or video or other random pixels) is to send the drawing commands to the server to draw into an off-screen pixmap in the X-server, then have the X-server do a blit from the off-screen area to the viewable screen buffer.

So, yes, I can know its not falling back to some non-X compatibility layer.

Mostly these days I don't bother with xscope, because performance is pretty good. The last time I used xscope was when I thought Gnome was pretty neat, but wondered why remote performance was so poor. When I ran gimp through xscope I saw what seemed to be the toolkit asking the X-Server thousands of times how big its window was. Every one of those calls had to be synchronous and had to make a round trip to the X-Server and back. I never saw if they fixed that, but the proper way to deal with window sizes in X-Windows is to track the window size in local variables that are updated by the X-Windows event notifications the come every time the window changes.

And one of the things that is observed is that the energy of the emitted photon is observed by an external observer to be altered by the kinetic energy of the moving origin. In the direction of travel the photon will be observed to have been blue-shifted, in the opposite direction it will be observed to have been red-shifted.

Because the ice only exposed to the ocean water on the bottom. On the top is air, and on the sides is either land mass or more ice. One of the ideas for why the area of Antarctic ice is increasing is because the new ice is frozen fresh water from the ice melt. The fresh water, being less dense than the salt water floats on top of the more saline ocean water. And, because it has less salt in it, the freezing point is higher, so it's easier to freeze. VOLUME is AREA*depth. Decrease the depth and the VOLUME drops.

Then there's the cube-squared law, for a given VOLUME, increasing the surface AREA by decreasing the depth, increases the heat transfer capability. So, thinner ice over a larger area can give off or absorb heat more quickly. If the average temp is below freezing, you'll observe more heat given off to the surroundings and more ice forming, if the average temp is above freezing you'll observer more heat absorbed from the surroundings and more ice melting.

The Antarctic ice cap is up to 45.5 million years old. 3000/45,500,000 = ? Then subtract some for the interglacial periods in the last 45.5 million years. That makes the accumulation rate miniscule. As well as having nothing to say about the current rate of accumulation.

QED is apparently mistranslated in this case.
