The article says that the melting is increasing sea level by 0.16 mm/year (of 2.6 to 2.9mm total sea level rise/year). And the estimated melted mass is 65 Gigatons/year.
What does your authoritative source have for the measurements of increasing Antarctic Ice mass? Especially in the interior of Antarctica (which is officially a desert climate)?
"Should" means "if this interglacial period were repeating the cycle of previous interglacial periods, the world should be cooling down".
I would classify avoiding having glacial ice sheets covering large tracts of the northern hemisphere as a good thing, yes. As in almost everything, moderation is best.
Except, of course that we're well past the average mid-point of an interglacial period and the climate should be headed for another period of glaciation. And given the current climate trends, the next period of glaciation seems to be moving into the future.
Additionally, Esquire magazine put him into the "Crazy Caucus" section of "The 10 Worst Members of Congress" with Michele Bachman and Steve King.
As a long-time resident of Minnesota, you have my abject apology for putting Michele Bachman in Congress. I'm not in her gerrymandered district, but I'm still embarrassed.
We had a PDP 8/I that the EE guys built a high speed paper tape reader for. One I/O addresss made it go forward, the other backward. Watching various sort algorithms run against data on the tape were educational in a unique way.
We also had a paper tape based 4K 2Pass Algol compiler that worked, it waited until you reloaded the freshly punched tape of intermediate format to start the next pass and gave you an loadable paper table on the final pass.
Really wishful thinking. While we're seeing articles about "cutting the cable" and binge show watching (without commercials). The television advertising groups are trying to convince their customers that everyone wants to be like television. I spend time and money avoiding commercials, because they waste my life-span.
Of course I understand. Mostly from having to debug and fix some of the multitude of ways that sort of "pattern" gets bollixed up. The biggest source of bugs in that instances of that pattern is the disconnect between the statements preceding each goto and the statements after the label. Do you have multiple labels? A label for each potential failing resource? An unwound set of labels? What convention are you using for the labels?
Or, the another possibility is recording everything that needs to be cleaned up. That introduces more state data that has to be initialized, maintained in a coherent state and cleaned up.
Now suppose that you have to change the order of setup because of a newly discovered hardware restriction. You potentially have to re-order the labels for your gotos, or which cleanup gets done after each label.
If the cleanup is done at the bottom of every block that is executed because of success, it is automatically done in the proper time and place.
Or, there's this variation I used while trying to remove a bunch of . (hidden) directories from a user directory. As root of course, otherwise it's not nearly as funny.
That process is already running in pilot plants in Germany. They're generating methane using a Sabatier process driven by excess renewable energy. The methane is injected into the national natural gas pipeline network. Typically national natural gas pipeline systems have a buffer of several days to weeks of supply.
The Wikipedia article is labeled Power to Gas http://en.wikipedia.org/wiki/P... There's a section for hydrogen and another section for methane. And of course, once you have methane and CO, you have feedstock for Fischer-Tropsch processes that provide liquid fuels.
While it isn't completely impossible for some sort of coating material to have solved the problem, it would be inventing technology that was almost certainly unknown at the time.
In the 1800s even under the copper plating, the seams were caulked with oakum soaked in pine tar, driven in place with a caulking mallet and a caulking iron, putty was then applied to the hull seams and the deck seams were payed with melted pine pitch. The weather deck of the ship had to be as water-tight as the hull or waves breaking over the deck would founder the ship in short order. That's another thing that the typical Ark description gets wrong.
The pictures I've seen of the interior of modern Ark replicas look more like barn framing than ship framing. Wooden cargo ship frames from the 1800s were large. For example, the Flying Cloud had floor timbers (think ribs) that were sided(along the length of the ship) 12 inches, moulded (outside to inside) 17 inches at the keel (typically white oak or live oak), space between the frames was typically the same as the sided dimension (12 inches in this case). The keel of the Flying Cloud was 3 layers of rock maple, moulded 44 inches, and sided 16 inches, with additional keelsons and sister keelsons, the ship was nearly 9 feet through the backbone. And, it was all bolted through and through with 1 1/4 inch copper and iron bolts. Even the garboard strakes (outside hull planks) were from 4 1/2 inches to 7 inches thick, The ceiling (inside hull planks) was a minimum of 4 1/2 inches up to 7 inches thick. Most of the planking and ceiling were southern pine.
The key phrase that describes something the purported size of Noah's Ark built from wood, is "Works like a wicker basket".
If you can't keep the hull from flexing, every time a section of the hull passes over a wave the frames and strakes will bend, the seams will open, and the sea will come in. Then, unless you have high volume bilge pumps running constantly, down the ship goes.
That depends on whether you know where the stored reading glasses are. I spent a couple of hours one time searching for my glasses because I hurriedly put them on top of the refrigerator and then couldn't see well enough to spot them. I felt a lot of sympathy for that character when I saw that episode again.
Someone above mentions exporting a video stream to handle remote sessions. I think that's actually a strong contender for a new User Interface system, but it discusses nothing about how that actually happens.
It the GPU exports an MP4 video stream that can be delivered directly to any display (local or remote) that deals with the last connection bottleneck. It's a standard, its ubiquitous, and its implemented in hardware. The return channel for user interaction needs to be done, but that doesn't have the performance issues that the presentation does.
The other piece of the system that needs to be handled is the API for the interface to the GPU hardware. A contender for that seems to be an API tied to EGL ES (if I read the acronyms right), and there should be others. That assumes the Khronos Group is doing something useful there. How many implementations are there of EGL ES to GPU hardware drivers?
The layer in the system between the user applications and the hardware interface is the place where QT, GTK, Windows graphics api, and all the other graphics toolkits go. Those toolkits shouldn't care too much about the hardware details, just the published capabilities of the GPUs.
It seems like there's a strong possibility that the replacement for remote X-Windows could be something conceptually simpler but could require one massive block of processing. (And I think Nvidia is most of the way there).
The remote presentation could all be done with an mpeg 4 stream, direct from the GPU. That chooses one standardized mechanism for presentation, and I think it should be sufficient for almost any sort of application. The presentation space in the GPU would be written with a number of APIs, but as the time came to present that image to the user, the GPU would transform the presentation space into an appropriate mpeg 4 frame and push it out some serialization interface for delivery to the end device.
The only additional interface required is for the user input device, which is non-trivial, but doesn't require the brute processing capacity that presentation requires.
Comfortable as in sheltered, warm in the winter, fed any time I feel like it any time of year, and dry when a thunderstorm has knocked out the power and is dumping on us.
To restate. Critical being the heating boiler (LP), some lights, the kitchen (except the electric oven), a sump pump, and a circuit for the living room and master bedroom. I grew up without running water and with wood stove heat. The current setup is way better than that. And it does last for days without starting up the generator.
Sure, the inverter/ATF is a Xantrex SW4048. The model has been replaced with other models. I've never had a problem with it, although I've heard some complaints about components in the newer models. The main service tie is a 30 amp 110 circuit, and there's a secondary input that I can drive with a generator or other 15 amp 110 source.
The batteries are Fullriver DC310-6 gel-packs which are supposed to deal with hydrogen out-gassing. I think the model number translates to 6 volt, 310 Amp hours. They're connected in series to yield 48 volts DC to the inverter.
The system was sized to run the critical circuits in the house for 3 days. (Critical being the heating boiler (LP), some lights, the kitchen (except the electric oven), a sump pump, and a circuit for the living room and master bedroom.
A demonstration plant for conversion of electricity to feed the natural gas network was ready in Germany in 2012. There should be more details here.

I've got a "whole house" battery backup that I installed several years ago for about $ (usd)8k. It has 8 batteries (6 volt gel packs in series) and a 3 Kw inverter with integrated auto transfer switch. That's been enough to run the critical systems in the house for 3 days (from experience). It doesn't run the air conditioning, but everything else works just fine.
No. Simply No. This is wrong. In almost every particular
The continents are masses of rock that are on average less dense than mantle rock. So, the continents are floating on the mantle rock. Upwelling plumes from the mantle are most often associated with volcanic activity and aren't "lifting the land up" at least in anything approaching a continental area. When ice melts off a continental area, that part of the continent will rebound, floating higher on the mantle rock. Some areas on the periphery of the land mass will sink due to the changing orientation of the mass, but the general motion is upward. All of this takes place over millennia. Parts of North America are still rebounding from the melting of the Laurentide ice sheet. The convective cells in the mantle have some effect on the height of different land masses, but those changes take millions of years to be measurable.
It has been observed for quite a while. At the Panama Canal, the Pacific Ocean average sea level is about 8 inches higher that the Atlantic Ocean average sea level.
Here's a prime example of someone speaking with absolute certainty and near complete ignorance.
The "extremely nasty" chemicals in the battery are aluminum and oxygen. Solid aluminum metal will yield 8kWh of electricity per kilogram of aluminum mass when reacted with oxygen. When aluminum first became an affordable material it was referred to as "solidified electricity" because of how much electricity the Bayer process consumed to refine bauxite. Also, the aluminum is basically consumed by being transformed back into aluminum oxide. But, if you run the alumina back through the Bayer process you get aluminum metal again. Pretty much a closed cycle.

Most of the interior is a desert, no more than a few centimeters of ice crystal precipitation per year.

So, bailing out leaves dangling threads, leaking memory, and deadlocks that show up the next time the function is entered.
