Tesla's Having Issues Charging In the Cold
Depends on battery chemistry. Most electric/hybrid cars seem to be congregating around Lithium Iron Phosphate (LiFePO4) batteries, which generally shouldn't be charged in the cold... it can cause lithium plating to accumulate on the anodes and if done repeatedly can eventually compromise the safety of the battery packs. Discharging (using) them below freezing is OK, but charging is not.
Cold War Spoils: Amateur Builds Telescope With 70-Inch Lens
It's an impressive amateur engineering feat, but its performance as a telescope might not be anything to write home about. It probably shares one quality with the hubble that you wouldn't want: a problem with gravity.
Remember how when it first went up, the hubble had problems focusing clearly? The designers forgot that its mirrors would be deformed/reshaped by the lack of gravity. Essentially, the hubble's primary mirror was optically designed to work as a telescope mirror on earth, not in space. It wasn't until the later mission to fix it with some corrective optics that it really achieved its best capabilities.
Now, since the surplus 70" mirror this guy used was designed to work on a satellite, it would very likely have the same problem but in reverse. If the mirror was designed to be shaped properly in a microgravity environment, it would also be deformed when on earth (as it is when used in the amateur telescope.) That might make the images from it quite a bit worse than one might hope for from a 70" instrument.
Signs Point To XKCD's Time Ending
Cool! I guess it's ending at Andrew Henry's Meadow... I loved that book when I was very little.
Kernel Dev Tells Linus Torvalds To Stop Using Abusive Language
Swearing and calling people names is one thing. But legitimate verbal threats can still be short of actually showing up at your door with a baseball bat. If a guy tells you he's going to show up at your door with a baseball bat, that qualifies.
Who Will Teach U.S. Kids To Code? Rupert Murdoch
I took AP computer science in high school, myself, and it really wasn't programming, it was pretty much the same as a college data structures class (arrays, linked lists, trees, sparse matrices, searching and sorting, etc.) Going straight into that without some earlier programming foundation doesn't really work so well. We need to start kids earlier to really get proficient.
The logic skills needed to code can be developed, too, but it needs support much earlier, including in elementary school math. I remember in 2nd-4th grade, our textbook was called "sets and numbers," and we did a lot with set theory, which my son's school hasn't. There are tradeoffs: he was into algebraic equations in 4th grade, which I never did until at least middle school. But overall it seems like he's had less emphasis on logic and discrete math and more on general/continuous math. My wife and I have tried to supplement it, but it isn't really standard anymore, where we live.
Anyway, if kids get enough practice with sets and set operations in elementary school, then logic operations a bit later (which and teach them how it's really the same, AND = intersection, OR = union, etc.) and throw in a few other concepts like variables, then they should be ready to start getting some early programming classes in middle school, which will stick with them a long time.
Man Of Steel Leaps Over Record With $125.1 Million To Mixed Reviews
That's too much like saying it re-enforces a simplistic worldview that there is such a thing as reality, whereas nothing is actually "real." After all, isn't "reality" just a stand-in for perception?
In an even more complex construct, it is equally simplistic to assume good and evil are not real as it is to assume they are. It all depends on how many levels of non-reality you want to contemplate, and how superior you want to consider yourself to those who adhere to "simplistic" world views.
Apple Updates MacBooks and Mac Pro Desktop With Haswell, "Unified Thermal Core"
Specifically it looks like a NeXT cube. Something tells me that's the wrong link, and that it doesn't look like that.
What Keeps You On (or Off) Windows in 2013?
Along similar lines, if you're dependent on a handful of apps most people have never heard of, because they drive something specific (like scientific equipment, or in my case, telescopes and cameras for amateur astrophotography) your chances of moving to Linux are poor. There's a lot of good open source effort devoted to making equivalents for things most people need, but when there aren't that many users, the community of potential open source developers is small.
My own list of boat anchors keeping me in the Windows pool includes MaximDL, PHD Guiding, PemPRO, FocusMax, and a bunch of drivers for things like telescope mounts, focusers, a CCD camera, etc.
And yes, there's virtualization, and such, but some of these programs and pieces of equipment are finicky enough to get to work together to start with, without that added level of complexity.
How much I care about GMO food labeling:
Not to mention my demographic: fanatically indifferent.
New Pirate Bay Greenland Domains Suspended
Heck, TUVALU had a TLD, until they decided they could get more out of selling ".tv" than having one themselves.
Automated System Developed To Grade Student Essays
Watch as we move from "search engine optimization" to "grading engine optimization," as students look for AI solutions to write their papers, freeing them for other tasks.
Is Daylight Saving Time Worth Saving?
As an amateur astronomer, I find evening hours of sunlight a waste. I'd rather have it get dark sooner, to extend useful observing time earlier into the evening rather than later into the night.
What the article is arguing for isn't getting rid of DST, it's making DST permanent--the worst possible solution. To argue for getting rid of DST, which is what I would advocate, you'd have to stay in the "fall back" time and never "spring forward."
A New Version of MS Office Every 90 Days
Thanks, I think I must have known that back at the time, but never paid attention to the DOS versions so it didn't stick. Word for Windows 2.0 was the first time I earnestly made the switch to Word from Borland Sprint on DOS.
A New Version of MS Office Every 90 Days
I don't know quite what to make of this. I got used to skipping every other generation of Office, especially MS-Word, back sometime around the time of Word for Windows 2.0 (which was great) and Word for Windows 6.0 (the next version, which was not... who knows what happened to 3, 4, or 5.) But then later, Office/Word 2003 was the last good version, before they totally messed up the interface with their "ribbon bar" or whatever they called it, that made its functions impossible to find and use.
Rumor was that Microsoft had two competing teams, and while team A was releasing one version, team B was prepping the next version. Then when team B went to release their version, team A went back to development.
Given the later performance, though I don't know that it still holds. I just know that every time they make changes, I definitely want time to watch others' use of it and see what they are before I accept the upgrade.

Will Renewable Energy Ever Meet All Our Energy Needs?
Stars and supernovas aren't quite a renewable resource, except possibly through initiating a new "big bang" and rebooting the universe. The universe ultimately uses energy and moves to increased entropy. New stars are formed, but the pool of matter and energy to form them from is limited; some is lost over time (think of loss to black holes, for example... no real way to recover matter once it reaches that state.)
If renewable energy doesn't exist, then the whole premise that any civilization--human or otherwise--could be powered entirely by renewable energy is moot.
J.J. Abrams To Direct Star Wars VII
...but nobody suspected that meant only one director.
In the end, it will come down to a fight between JJ Abrams and Peter Jackson?
Wikimedia Moving Main Data Center To Ashburn, Virginia
Also most of Ashburn is fairly new construction compared to other locations nearby and most of its power lines are buried... that probably contributes to it keeping power on when older communities in Fairfax and Maryland don't. I suspect also the choice of location may have something to do with proximity to others. UUNET (or whatever they are these days), AOL, Verizon, etc., etc.
Swedish School Makes Minecraft Lessons Compulsory
''They learn about city planning, environmental issues, getting things done, and even how to plan for the future,"
My son must have somehow gone to that school without telling me. He keeps talking about Creepers being a key natural resource.
Investing In Lego Bricks For Fun But Mostly Profit
I could see this working as a short term investment, rather than a long term holding. For example, there was an "ultimate collector series" millenium falcon they made (which was huge, much bigger than the set my son plays with) that sold for about $500. If I'd thought about it, I'd have realized it would sell out and that only a couple of years later, it would be worth $1800-2000, for about a 200% to 300% profit. It's not major income, but a small, short term thing that could have generated some hobby funds or something.
