Oh, teleportation? If it can really take kids on a field trip anywhere, that would be awesome.

If all it does is encourage teachers to give kids more computer time in place of field trips, that's kind of lame.

It's shockingly easy to get worldwide attention with a totally bogus study. Simple recipe: measure 20 variables in a small sample group, and it's likely that one of them will "win the lottery" and seem statistically significant. Nice job demonstrating this.
“Slim by Chocolate!” the headlines blared. A team of German researchers had found that people on a low-carb diet lost weight 10 percent faster if they ate a chocolate bar every day. It made the front page of Bild, Europe’s largest daily newspaper, just beneath their update about the Germanwings crash. From there, it ricocheted around the internet and beyond, making news in more than 20 countries and half a dozen languages. It was discussed on tel...

What most people don't realize when they read about billion dollar startup valuations: VCs won't be holding the bag if the eventual value is less, because they will get paid first, and employees lose. “You pick the valuation and I’ll pick the terms.”

The future is unknown, tough to know beforehand if there really is a bubble.

"Google now has a significantly lower cost in standard compute instances"...without any commitments, prepayments, or restrictions. And RightScale's analysis excludes the additional 14%* savings you get from per-minute billing and never having to exactly guess right which machine type or region you'll need.

"14% extra, really?", you might ask.  14% is an estimate, of course, and YMMV -- see http://cloud.google.com/pricing for more, including a TCO calculator where you can check our math and plug in your own assumptions. But it's not a contrived number: consider this simple example: suppose you're running some hadoop jobs that on average take 2 hours.  On GCP you pay for exactly the minutes you use.  AWS will round up to the next hour, so on average you'll overpay for 30 minutes, which is a +25% surcharge on the advertised VM rate.  

On GCP, "pay only for what you use" means exactly that.
The Google vs. AWS pricing battle over cloud compute power continues with new Google price cuts. RightScale has the latest analysis and comparison charts.

I'm kind of surprised Azure isn't included in that comparison.

Now the decade of work we put into NoSQL is available to everyone using GCP.  One way it shows that we've been working on this longer than anyone else: 99% read latency is 6ms vs ~300ms for other systems.

How are you getting to 6ms write latencies?  Are the writes not guaranteed to survive a region failure?

I was catching up on my reading and came across this gem of a paper in the April 2nd issue of Nature (though the article is helpfully marked as "appeared first online on April 1st).

From their conclusion: "Sluggish action on global warming is set to compound the problem, and policies such as the restoration of knighthoods in Australia are likely to exacerbate the predicament yet further by providing a sustained and delicious food supply." :-)

Full paper: http://www.nature.com/nature/journal/v520/n7545/full/520042a.html
Emerging evidence indicates that dragons can no longer be dismissed as creatures of legend and fantasy, and that anthropogenic effects on the world's climate may inadvertently be paving the way for the resurgence of these beasts.

Awesome video about how hard it is to learn to ride a bike where the handle bars steer the opposite way. And how easy that is to learn for a four year old.

+Rich Martin Maybe you are right, companies should really be using the "honour" system.

If you use someone else's stuff, you should be happy to pay them for it. It is the ethical and honourable thing to do.

Finding loopholes by making just the compiled byte-code different so you can get around being caught is an absolute indicator that you agree that you are ripping off someone else's efforts without having to invest any of the money that they initially did.

I just don't get it. G has the cash, just pay for Java. The side-effect of a precedence like this could be damaging to everyone else in the industry. As Rich says, it will really muddy the water if defined generally.
In G's case with Android, it appears an obvious theft on the surface.

What would your mom say?

Finally!
As FIFA leaders gathered for a meeting, Swiss law enforcement officials arrived unannounced and made arrests at the Justice Department’s request on charges including racketeering and money laundering.

that the fifa is a pool of corruption is hardly news.  but now it's showtime for the new US attorney in chief.  remember that US attorneys in chief are the kinds of people that make sure not a single banker goes to jail when they run the global economy into the ground.   I'm glad the fifa isn't too big too fail, I don't feel sorry for their arrested officials and i hope they get trashed by the swiss police like other foreigners are on a regular basis.  I look forward to mr Blatters public weaslings on how he knew nothing and will clean the house, but just realise that you, dear public are being played here like an official ball of the Worldcup.

I suspect Ms Lynch real job is to distract the attention from the real crimes.

Great to see CS become more like other disciplines where women represent 50% of graduates. As a field we're still way off but progress made in just the past few years is encouraging.
A new prize aims to recognize colleges that succeed in attracting women into information technology, a field where they remain underrepresented.

+Jay Geater You do know that programming was once relegated to women because it was, err, "soft" and not considered as important or challenging as the "manly" engineering tasks of diddling with hardware. And then the world changed. Software became the thing ( read "lucrative"). And when software was where the money was, men moved in and claimed that women were too hormonal to do, wait....what was it exactly?

Why we're just about to retire the corporate intranet: it's not secure.
Google is moving all of its internal apps to the cloud and changing the security in tow. Read More

The point isn't that the cloud is as secure as the internal network. It's that the internal network is as insecure as the cloud.

Now a classic experiment but still fun to watch, and still surprising (at least to me): monkeys have a very acute sense of fairness.
