Finland Dumps Handwriting In Favor of Typing

Re:Finland will save money on napkins (523 comments)

Ok, so you get given 192.168.14.50 and told there are a maximum 14 hosts.

Maximum 14 hosts means it's 15 on the netmask, so 4 bits, so it's 32 - 4 = 28 network mask.

That means the networks increase by 16 for each. The nearest multiple of 16 to 50 is 48, so the network is 192.168.14.48/28

The broadcast is 48 + 16 - 1 = 63 -> 192.168.14.63

There are some additions and some subtractions and some multiplication, but I don't see where the long division comes in. Do you have a different method of calculating these?

Graphene May Top Kevlar As a Bullet-Stopping Material

Re:for all this talk... where is it? (129 comments)

10 years ago they had been saying 10 years already.

No they hadn't. The "scotch-tape technique" was what suddenly made graphene the new wonder material that could be produced relatively cheaply. It was invented in 2004 - just about 10 years ago.

Wind Power Is Cheaper Than Coal, Leaked Report Shows

No, at a temperature of around 20C, vapour pressure increases about 6.4% for a 1C rise in temperature. So a rise of around 5% sounds about right.

You can calculate it yourself using the "Antoine equation" if you don't believe me (which you shouldn't).

You Got Your Windows In My Linux

Re: What's wrong with Windows Server? (613 comments)

I'm afaid it is _exactly_ how X works. The X "server" needs to reside on your local host to see remote X applications displayed locally.

The AC thought you needed the X Server installed on the remote machine and considered it a security risk. That is exactly how it does *not* work. As you have just stated: the X Server runs on the local machine, not the remote server.

I know it's a little confusing referring to the 'server' and the 'X Server' as two separate entities, but I'd hoped my example - specifically stating which machine didn't have the X Server installed - would make it clear enough?

You Got Your Windows In My Linux

Re: What's wrong with Windows Server? (613 comments)

It still requires you to run X on your server even if you are using a remote client.

No it doesn't, that's not how X works. Try it for yourself. Create a new VPS on your favourite provider and do:

ssh -X somemachine
sudo apt-get install x11-apps

Note it doesn't install X11 itself. Type 'xcalc' and notice that xcalc starts in a window on your local machine. It's really that easy.

Study: Antarctic Sea-Level Rising Faster Than Global Rate

Re:What will it take to abate your fear? (302 comments)

That climate change occurs naturally is no reason to think it can't also occur artificially. That's like saying that since fire has existed since the earth began, there's no such thing as arson.

You also fail to understand the "oceans storing heat". We measure how much energy the earth absorbs and how much it radiates. The difference must go somewhere. The amount of atmospheric warming plus the ocean surface warming plus ice melting etc etc don't amount to enough to cover the amount of energy absorbed, so either those things are warming *more* than we measure, or the energy is going somewhere we don't measure. So the deep oceans are the best bet. If you have another theory (that doesn't involve the energy being waved away by the natural cycle fairies) then feel free to share.

Perhaps learn some physics first though, yes? (Why do Americans say "physics" but not "maths"?)

Neanderthals Ate Their Veggies

Re:One Sample (151 comments)

The other Homininae digest plant matter, so why should we think that Neaderthal did not eat any plant matter?

Because it's a good idea to think you might be wrong. It encourages you to think of ways to *prove* that you're wrong.

Seagate Releases 6TB Hard Drive Sans Helium

Re:Oops in title - "sans" ? (147 comments)

Doesn't "sans" mean without?

Yes, that's because WD's 6TB Ultrastar He6 was hermetically sealed with helium inside, something the company said was critical to reducing friction for additional platters, while also increasing power savings and reliability. Seagate, however, said it doesn't yet need to rely on Helium to achieve the 50% increase in capacity over it's last 4TB drive.

At least, I'm sure I read that somewhere.

Nate Silver's New Site Stirs Climate Controversy

Re:Cherry Picking is Much of the Issue (335 comments)

No, it's more like:

If you pick 17 years you get one conclusion.*

If you pick 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33 or 34 years you get another conclusion.

(*actually, you don't. I've no idea where this "17 years" thing came from. The temperature data shows a rise over the last 17 years)

Pro-Vaccination Efforts May Be Scaring Wary Parents From Shots

Re:You cannot UN-VACCINATE your child or pet (482 comments)

Physicists Test Symmetry Principle With an Antimatter Beam

Re:Feynman tutored me in QM at Caltech (106 comments)

I'm afraid you've been wrong since 2nd grade then.

The mirror is actually misleading. Here's an alternative question:

Why, when you're facing another person, are your left and right reversed, but your up and down the same?

Bonus question: It's easy to describe what up and down are (down is closer to the Earth, up is further away). How would you describe left and right?

How Well Do Our Climate Models Match Our Observations?

Or "The fact is that we can't account for the lack of warming at the moment and it is a travesty that we can't. The CERES data published in the August BAMS 09 supplement on ... shows there should be even more warming: but the data are surely wrong. Our observing system is inadequate."

Heh, I love it when deniers mindlessly repeat that quote. You don't even know what it means, do you? Because if you did, you certainly wouldn't be mentioning it.

You see, we measure how much energy the Sun outputs. And we measure how much the Earth reflects of that energy (its albedo). We also measure how much it radiates, which - if the Earth was at a stable temperature - would be the same as the difference between the first two. Understand so far? That's what the "CERES data" refers to.

What Trenberth is saying is that the CERES data shows there should be far *more* warming than we're actually measuring! When you take into account air temperature increase, melting ice, sea temperature increase, etc etc it *still* leaves a big chunk of energy to account for. Now, any sane person would therefore assume that the energy can't just vanish: it's got to go somewhere that we aren't measuring.

Not the deniers, they think it's all being whisked away by the natural cycle fairies. Or perhaps they just don't understand what it is they're saying and are mindlessly repeating what they read on some blog. Hey, maybe you can tell us. Which is it?

NYT: Healthcare.gov Project Chaos Due Partly To Unorthodox Database Choice

/dev/null seems to have great writing performance but has terrible reading performance. I wouldn't recommend it.

That's because it blocks while waiting on zero point energy. If performance is an issue, you can use /dev/unull instead, if you don't really need high quality nullity.

Humble Bundle: Linux Users Pay Most For Music Too

dylan_- (1661) writes "It's well known that in the various game Humble Bundles — pay whatever you want for a variety of games — Linux users have consistently been the ones who voluntarily pay the most. Some have attributed this to the lack of games on Linux but the latest Bundle is for music rather than games and the trend continues. Linux users paying an average of \$11.95, Mac \$9.92 and Windows \$7.50. Perhaps the old complaint of it being more expensive to hire Linux sys-admins is correct, meaning they tend to earn more and leaving Linux users with more disposable income?"

Latest Humble Bundle Hits \$1 Million

dylan_- (1661) writes "The Humble Frozen Synapse Bundle — where you pay whatever you want for a collection of games — has just hit the \$1 million mark with 1 day and 9 hours left to buy. The games are DRM free, available for Windows, Mac and Linux, and include a donation to the EFF and Child's Play charity. As with previous bundles, Linux users are the most generous, paying an average \$9.18, Mac users come in second paying \$6.58 leaving Windows users lagging behind, paying \$4.11 on average."

Humble Bundle: Linux Users Pay Most

dylan_- (1661) writes "It's the last few hours of the Humble Indie Bundle deal, where you pay as much or as little as you want for five indie games. At time of writing, they've taken about \$888,000 dollars from 100,000 contributions. The lowest payers are Windows users at an average of \$7.75, with Linux users almost doubling that at an average of \$14.26.

If you fancy getting hold of any of World of Goo, Aquaria, Gish, Lugaru or Penumbra Overture for cheap (or even expensive: the largest payment so far is \$1000!), you have about 8 hours left."

Dirac 1.0.0 released

dylan_- (1661) writes "According to their website, "Dirac is an advanced royalty-free video compression format designed for a wide range of uses, from delivering low-resolution web content to broadcasting HD and beyond, to near-lossless studio editing." Now a stable version of the dirac-research codebase, Dirac 1.0.0, has been released. The BBC have already successfully used the new codec during the Beijing Olympics and are looking to push it to more general use throughout the organisation.

The latest version of VLC (the recently released 0.9.2) has support for Dirac using the Schroedinger library."
