This is seriously cool.

Researchers gave the AI only the raw video, the buttons on the game controller (but not what they do in-game) and the high score and told it to go play. The AI now plays Atari video games at superhuman levels, without any guidance or direction from researchers.
 
Shall we play a game?

Researchers at DeepMind have published a paper in the journal Nature wherein they describe a novel algorithm, called a deep Q-network (DQN), that can learn to excel at a wide variety of classic Atari 2600 videogames — everything from side-scrolling shooters to boxing to 3D car racing — using only the raw screen pixels, a set of available actions and game score as input. 

By using a neurobiologically inspired mechanism, termed experience replay, DQN performed at more than 75% of the level of a professional human player in more than half of the 49 games tested, sometimes even developing long-term strategies for success. Head over to the Google Research blog to learn more about the Machine Learning framework that made this possible.

Jupiter Ascending is possibly the most insanely lavish visual feast I have laid eyes upon. It's all the most gloriously beautiful fever-dream sci-fi concept art ever all brought to life in 3d.

However, the plot manages to limbo under my already low expectations and the acting and dialogue manages to be even worse. This is the most beautiful bad movie every made, and boy is it bad.

But still: pretty! I'd love to see the Wachowskis apply this visual style to Dune - it would be stunning - as long as they stay far away from the script.

I've linked to the concept art; the movie is even prettier in 3d on a big screen. Even though it's a truly awful movie, I'm still happy as I got what I expected: tons of eye candy (and superfluous plot/acting that is better left ignored)
The Wachowskis' latest science-fiction experience, Jupiter Ascending, may stumble as a film, but it's certainly a feast for the eyes. As we join Jupiter Jones (Mila Kunis) on her journey across the...

Have to agree, visually great but otherwise kinda sucked. Just rewatched Avitar and wow. Visually incredible, and yes it's Pocahontas modernized, but wow.

Ok, this is now my favorite Street View location
 
Have you ever wanted to tour the #USNavy's oldest commissioned warship, but haven't been to Boston? Well, thanks to +Google, you can see USS Constitution's cannons, galley, berthing and much more!

Take the virtual tour now! http://bit.ly/1C5OczV
USS Constitution (nicknamed "Old Ironsides") is the world's oldest commissioned warship afloat and actively sailed the world's oceans in defense of the United States from 1797 to 1855. The ship is permanently home-ported at Boston National Historic Park in the former Charlestown Navy Yard in Boston, Massachusetts. (Source)

+Tim Nguyen we also use the inside restaurants view to decide "is this somewhere we can bring a kid to" a lot.

"The man was using his Google Glass for up to 18 hours a day..."

Dang, I want to know how he's getting 18 hours - I only get 4-5 hours of battery life on my Glass...

Also, even though I love it, Glass is one of the least addictive pieces of technology I use daily. It's not something you can fiddle with and play with for hours on end. It does a few things well, right when you need it, but otherwise stays out of the way. If anything, it has greatly reduced the interference of technology with life for me - a lot less compulsive checking the phone, no more holding the phone in front of me to take pictures instead of engaging, etc.
A Google Glass user is being treated for Internet addiction disorder at a Navy abuse program. This is the first known case of Google Glass addiction.

Don't panic. If Google didn't already force a password reset on your account, your Google Account is safe.

"We found that less than 2% of the username and password combinations might have worked, and our automated anti-hijacking systems would have blocked many of those login attempts. We’ve protected the affected accounts and have required those users to reset their passwords.

It’s important to note that in this case and in others, the leaked usernames and passwords were not the result of a breach of Google systems. Often, these credentials are obtained through a combination of other sources. 

For instance, if you reuse the same username and password across websites, and one of those websites gets hacked, your credentials could be used to log into the others. Or attackers can use malware or phishing schemes to capture login credentials."

Must have for parents!

From a sample size of one I can say that the little one loves it. And I've never encountered anything not-child-safe on it. Now, strange things, that's another story - I'll never understand the appeal of watching people open vending machine toy eggs, but apparently kids love it...

I served this very wine (among others) at my own (kosher Jewish) wedding, mostly because it was a little different from and quite a bit more affordable than kosher sparkling wine of any drinkable quality. Funny to see how it's apparently now mainstream, popularized by hip-hop artists.

BTW, Golan Heights Winery in Israel makes the best moscato, kosher or otherwise, that I've had. Just sayin'.

If you've ever wanted to use a secure, unphishable cryptographic token to protect your logins, well, yesterday was your lucky day. These are vastly more secure than OTP generators and the like as well as being easier to use, presuming your platform supports it.

Here's hoping that other websites and banks start supporting this soon!

The infamous "real names" policy is now gone.

About bloody time.
 
When we launched Google+ over three years ago, we had a lot of restrictions on what name you could use on your profile. This helped create a community made up of real people, but it also excluded a number of people who wanted to be part of it without using their real names. 

Over the years, as Google+ grew and its community became established, we steadily opened up this policy, from allowing +Page owners to use any name of their choosing to letting YouTube users bring their usernames into Google+. Today, we are taking the last step: there are no more restrictions on what name you can use. 

We know you've been calling for this change for a while. We know that our names policy has been unclear, and this has led to some unnecessarily difficult experiences for some of our users. For this we apologize, and we hope that today's change is a step toward making Google+ the welcoming and inclusive place that we want it to be. Thank you for expressing your opinions so passionately, and thanks for continuing to make Google+ the thoughtful community that it is.

This is one of my favorite restaurants in Austin; I've been missing it ever since I left. Chef Alejandro's passion for inventive cooking exudes through everything. They also have a very thoughtful and eclectic wine selection, and I do consider myself a bit of a wine snob.

Contemporary American-French cuisine. Go for the chef's tasting menus for a long relaxing meal. They're great (vegetarian-friendly, even!) and be sure to pair with wine (they have a fabulous selection and a good sommelier). Friendly and knowledgeable staff. Definitely a favorite "special occasion" place.
