Satellite Images Show Russians Shelling Ukraine

geogob Re:Why the fuck is this on Slashdot? (571 comments)

Like any other site, this site is about that what the editors choose. Not the people consuming the information. It is the case for any type of media... why would you believe it is any different with this one?

You are always free to write your thoughts to the editors or to the editor who accepted the submission. Ranting about it is probably the least helpful thing one can do.

Android Leaks Location Data Via Wi-Fi

geogob Enough time to connect to Wi-Fi (112 comments)

"[...] because it clearly denotes in human language places that you've spent enough time to use the Wi-Fi."

I though driving by an open hotspot on the highway was enough time to use it. At least they would know on which Highway I drove.

How Did Those STAP Stem Cell Papers Get Accepted In the First Place?

geogob Re:The same way many global warming papers got pub (109 comments)

Although alternative spelling may be current, there is only one correct spelling. Ignoring the correct spelling, doesn't make the common alternative spelling suddently correct.

New Car Can Lean Into Curves, Literally

geogob Re:But it gives the driver the wrong impression (243 comments)

That's why the car is filled with other systems doing the feeling and adjusting for the driver, systems such as the ESP. it becomes essential in cars where de driving feeling disappears.

But its Mercedes... I drive regularly fully equipped E class Mercedes. It's awful. Its full of systems driving for you and taking decisions for you... It can go as far as breaking you on the highway. These cars are at 90 degrees of the "driving feeling" concept.

New Car Can Lean Into Curves, Literally

geogob Re: Gimmick (243 comments)

They all work this way. Doing a high speed train without such a system is not practical because it limits the speed for a lot of curves. The ICE 3 was the first to implement it to my knowledge.

I bet it would sell, a car that considerably leans outwards... "Feel the weightlessness in those curves".

SpaceX Landing Video Cleanup Making Progress

geogob Re:Digital vs analog (54 comments)

But you wouldn't get it through the telemetry data feed. You'd have to have an separate analog transmitter just for the video feed. I'd say that it would be worth it if the video feed was critical. I doubt it is... it's most likely only a nice to have feature.

SpaceX Landing Video Cleanup Making Progress

geogob Re:cheap webcam (54 comments)

The technical challenges of running a telemetry link with something falling through the sky from a moving aircraft has little to do with that of plugging two televisions together over a wired network. I'd expect the bandwidth for the video to be, in fact, comparable to that of a dial modem, especially considering that the bandwidth is shared with a lot of other housekeeping data which are probably much more important and useful than the video feed.

Google Has Received Over 41,000 Requests To "Forget" Personal Information

geogob Re:Google has NO responsiblity whatsover (138 comments)

Don't like what A said about B? Take it up with A.

I don't know in what world you live, but in the real world, there are so many hurdels to that process that it's in many case impossible (Understand, for example, no juridical basis or not affordable).

It has long been known that what you post online[...]

How about what is online and you didn't post yourself? Oh yeah, take it up with A.

I find your view of the world quite naive. I am not convinced that the solution requested by the European Court the best is, but it's a step in the right direction.

Is It Really GPS If It Doesn't Use Satellites?

geogob Re:Man-portable supercooling? (298 comments)

They are not using helium as refrigerant, but as pressure transfer medium in a pulse tube for the Stirling cooler. It allows you to decouple the compressor from the cold finger and avoid the need of mechanical piston on the detector side. These detectors typically run between 40 and 80 K, too cold to use nitrogen as transfer gas, hence the use of helium. In any case, the operation range is far from the super cooled case.

Is It Really GPS If It Doesn't Use Satellites?

geogob Re:Man-portable supercooling? (298 comments)

No they don't. Thermal imagers typically work around 50 K (based on HgCdTe sensors). This is easy to reach with a portable device, but isn't anywhere close to super-cooled. Higher performance thermal imagers may run at 3 to 4 K, cooled with liquid helium. There you are already far away from the portable solution, and again not even close to super-cooled.

To reach super cooled temperatures (we are speaking of mK, if not uK or nK), you'll need a truck to move the stuff around. Just the ultra high vacuum vessel and the turbo pumps, allowing you to reach vacuum better than in orbit at 200 km altitude, are enough... and you haven't started to cool yet.

US Officials Cut Estimate of Recoverable Monterey Shale Oil By 96%

geogob Re: Presentation of math (411 comments)

It's a reduction from about 2740 Library of Congress to about 120 Library of Congress (assuming the approximate volume of all three LoC buildings).

US Officials Cut Estimate of Recoverable Monterey Shale Oil By 96%

geogob Re:Presentation of math (411 comments)

From TFA :
The reserves were downgraded by 96 percent, from 13.7 billion barrels estimated by a government-funded report in 2011, to just 600 million barrels, the EIA said.
Absolute values help put things into perspective.

Or do we need more perspective? For those who prefer the typical journalistic approach to understanding numbers, it's a reduction from 872'000 Olympic pools to just under 37'200 Olympic pools.

Rising Sea Level Could Put East Coast Nuclear Plants At Risk

And why to you assume it is always bitter cold everywhere on Antarctica. All the time. Did TV say that?

Rising Sea Level Could Put East Coast Nuclear Plants At Risk

geogob Re:Where does 7 feet of water come from? (323 comments)

Please stop with the half-assed facts. The average temperature of the coldest region of Antractica is -57C. That has nothing to do with the average temperature overall on the continent. What you wrote is just as stupid as saying nobody will get a heat stroke anytime soon in Pheonix; the average temperature in Vail is 11C (52F) after all.
