Have you been asleep? Around 1990, a rechargable AA battery had 500 mAh capacity, took 14 hours to charge and had memory effect issues (NiCd, remember?). These days AA means 2500 mAh NiMH rechargable in under 1 hour. Li-ion is even better but generally not available in AA (cell chemistry means a much higher voltage per cell). So that's 2 entirely new battery chemistries and a 5-fold increase in capacity.
Also, you may not want to read about early research, but I do. If you want nothing but product announcements, go read manufacturer press releases instead of coming to Slashdot.
Don't be an idiot. Since 1981, the TGV lines have carried one billion passengers without loss of life.
The accident was on a newly-constructed line not open to passengers yet. They have thoroughly simulated both the trains and the line, but at some point you have to switch from simulations and actually run a train on your new track.
And let's wait for the accident report before mouthing off about imagined incompetence, huh?
If these ads use the same frequency range as those "ultrasonic" mosquito repellants, they're only ultrasonic to people whose hearing has started to deteriorate. I can hear them just fine, thank you.
I noticed something odd was going on when yesterday morning my OS wanted me to sign into the App Store to 'validate' a program I purchased recently.
Now I have to read about the cause on a news website instead of hearing directly from Apple (you know, the people who already have my email address along with those of all their customers).
The solar system barycenter wanders around, and is outside of the sun only part of the time. IIRC only the combined influence of several planets in alignment gets the barycenter to be outside the sun.
Personal hovercraft have been available for decades now. They're mostly used as toys because they have lousy directional control: only a rudder in the propwash, unlike large hovercraft which usually have vectored thrust at several points.
A program that constantly monitors my documents, and warns when a document is encrypted. That would give me time to stop the next backup from happening (so I can prevent the malware from accessing the backup medium), and to nuke the malware before it can do more damage.
Orbital height isn't the main problem. The station has parts that deteriorate and would be very difficult to replace. E.g. seals between the initial modules. These are necessary to keep the station airtight, and replacing them would mean disassembling half the station.
The Mastercard CC 'online banking' website where you can check your withdrawals etc. is a pile of shit: - lousy security (password A-Za-z0-9 only and with a maximum of 10 characters) - the information reported on each purchase is often useless, with an entirely different company listed than the place you actually purchased from, with limited-length fields chopping off half the name etc. - unnecessary jumping-through-hoops to download monthly statements (and no, you shouldn't name them all "download.pdf") - no way to download a list of transactions in a format importable in a finance app or spreadsheet - no way to get an alert for withdrawals
More purchases via CC = more need for monitoring, but as it stands it's a website I avoid as much as possible.
You're overreacting with your "unpopulated areas". Data centers should be in industrial areas, which are zoned for noise and pollution, and far enough away from residential areas not to bother people. Generally these are located on the outskirts of a town. A distance of 1-2 km from residential areas will suffice for almost every industry. That's within easy commuting range.
All these Uber stories are just the same old arguments rehashed over and over again. It's not news anymore, please can we stop getting informed whenever anyone vaguely related to Uber farts?
For the Space Shuttle, this article describes the process pretty well. Of course, the first release of the Shuttle flight software cost half a billion dollars.
Um, no. The cable being laid at the moment goes from Finland to Germany. A Northeast Passage cable would go from the other end of Finland, along the Russian coast to Japan.
The route above Russia is too long a route with little or no commercial demand. No financing would be available and there are too many ice scour issues in East Siberian Sea to make this route preferable over the Northwest Passage route.
is the plan for a cable under the Northeast Passage. A sea lane that used to be blocked by ice most of the year. I wonder if they've done feasibility studies, or if that "plan" is just a data center owner's wishful thinking.
This is about the long-standing and well-known issue that cars use more fuel and pollute more when tested on the road vs. the NEDC standardized rolling road test. This is due to the fact that the NEDC uses a driving profile (throttle position vs. time) that is much slower than the average car is driven. Bottom line: when you put the pedal to the metal, of course you're going to burn more fuel.
A Plutonium-238 RTG is an alpha emitter. All of its radiation is stopped by the casing. As long as you don't cut it open and eat the fuel, you're good.

doesn't a lithium ion battery already have an anode made of graphite?

They weren't the same size as telco racks (i.e. 19")?

I enjoyed a nice bottle of English wine a couple of weeks ago. There are vineyards today all over the south coast.

If service is bad, he'll not only refuse to tip
Why is that a bad thing? Isn't the whole point of tips to reward good service?

There were plenty of tests of individual boosters before STS-1.
The tonne is also known as the metric ton. It's entirely possible "a billion tons" refers to metric tons.

The new definition involves counting exactly 60 200 000 000 000 000 000 000 000 000 hydrogen atoms.
Um, no. The cable being laid at the moment goes from Finland to Germany. A Northeast Passage cable would go from the other end of Finland, along the Russian coast to Japan.
When plans for the undersea link to Germany were unveiled last year, he [the minister] mused that it could one day be hooked up via Finland to another that could run under the Northeast Passage - providing a superfast data route to Asia.
Conceded, more than a data center owner, but "mused" and "one day" doesn't exactly sound like they've finalized their plans.
And another company working on undersea cables in the Arctic (working on a route from Europe via Canada to Asia) has its doubts:
The route above Russia is too long a route with little or no commercial demand. No financing would be available and there are too many ice scour issues in East Siberian Sea to make this route preferable over the Northwest Passage route.

I might want information about my car to be displayed on my phone. I do NOT want it sent to Google.
