"Imagine this: a leak on WikiLeaks showing YOU explaining the evilest technology on earth! :-)," Hacking Team CEO David Vincenzetti wrote in a June 8 e-mail to company employees... "You would be demonized by our dearest friends the activists, and normal people would point their fingers at you."

I guess we don't have to imagine anymore.

The dealings of these modern-day arms dealers (selling, of course, to intelligence agencies and repressive governments) is every bit as unsavory as you can imagine.

What happens when you take a neural network trained to recognize images and run it "backwards" to produce images out of nothing?

Apparently this is what happens when AIs go on bad acid trips.

Do read through to the research blogpost; it's quite accessible even to those with little familiarity with neural networks. The gallery contains some weird and strikingly beautiful images mixed in with the frankenanimals and fields full of eyes staring at you.

Now that's one heck of a "coming to America" story!

Stole a military helicopter, evacuated family, followed random US helicopters in vague hope of finding a ship, helicopter too big to land, hover above fantail of moving destroyer while tossing family down to sailors below, then ditching helicopter in the sea and swimming out for rescue.
It was a scene that could have been ripped from the script of "Mission Impossible." This is the story of a Vietnam war hero you've never heard of.

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'.

I can't think of a better way for the SF Pride festivities to start.
Bay Area residents, politicians praise high court decision that makes same-sex marriage the law of the land.

I've been using this for a while, and the search is pretty amazing. This is great for those of us who are too lazy to meticulously organize and tag photos. The image recognition is decent enough to largely pull out the right things, and if you have kids the face clustering is great for cute nostalgia.

+Bradley Horowitz described Google Photos in an interview with Steve Levy as Gmail for your photos. Unlimited free storage, powerful search, access from anywhere...

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.

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.
