A senior commander with the Afghan Taliban says the militant group's leader Mullah Akhtar Mansour has been killed in a U.S. drone strike. Mullah Abdul Rauf told The Associated Press Sunday that Mansour died in the strike late Friday night. He says the strike took place "in the Afghanistan-Pakistan border area." The office of Afghan President Ashraf Ghani confirmed the strike but could not confirm Mansour's death. Chief Executive Abdullah Abdullah, however, says that Mansour is "more than likely" dead.

This week's economic calendar is pretty light. Market participants will be looking to an early getaway for the long weekend. While there will be plenty of entertaining FedSpeak, I expect a different topic to be at the fore. The news was pretty good, but the stock market was not. In my last WTWA, I predicted that the punditry would be asking whether it was "springtime for housing". That was the recurring topic as housing news was reported on several different days and garnered plenty of discussion. Competition came from the Fed Minutes, some dramatic earnings reports, and the election race. I always start my personal review of the week by looking at this great chart from Doug Short.

Four sister robots built by NASA could be pioneers in the colonization of Mars, part of an advance construction team that sets up a habitat for more fragile human explorers. But first they're finding new homes on Earth and engineers to hone their skills.

Recent work in distance metric learning has focused on learning transformations of data that best align with provided sets of pairwise similarity and dissimilarity constraints. The learned transformations lead to improved retrieval, classification, and clustering algorithms due to the better adapted distance or similarity measures. Here, we introduce the problem of learning these transformations when the underlying constraint generation process is nonstationary. This nonstationarity can be due to changes in either the ground-truth clustering used to generate constraints or changes to the feature subspaces in which the class structure is apparent. We propose and evaluate COMID-SADL, an adaptive, online approach for learning and tracking optimal metrics as they change over time that is highly robust to a variety of nonstationary behaviors in the changing metric. We demonstrate COMID-SADL on both real and synthetic data sets and show significant performance improvements relative to previously proposed batch and online distance metric learning algorithms.

The Taliban has denied reports that a US military drone strike had killed Afghan Taliban leader Mullah Akhtar Mansoor and another fighter in Pakistan. Earlier on Saturday, a US official said that the drone attack "likely killed" Mansoor inside Pakistani territory. Authorised by US President Barack Obama, the strike took place at about 6 am EDT (1000 GMT), the official said, which would have placed it late on Friday night in the target area. Multiple US drones targeted the men as they rode in a vehicle in a remote area in Pakistan along the Pakistan-Afghanistan border, southwest of the town of Ahmad Wal, the official added. The Pentagon confirmed that the US targeted Mansoor in a statement released on Saturday.

U.S. special operations forces launched an airstrike Saturday against Taliban leader Mullah Akhtar Mohammad Mansour in a remote town in Pakistan, U.S. military officials said, and initial evidence suggested Mansour was killed. U.S. military and intelligence officers were still assessing the results of the strike by multiple armed drones, they cautioned. The operation, which was authorized by President Obama and took place around 3 p.m. local time (3 a.m. Pacific time), hit Mansour as he traveled in a vehicle with another man along the Pakistan-Afghanistan border, southwest of the town of Ahmad Wal. Mansour has emerged as the leader of a resurgent Taliban that in recent months has mounted a powerful insurgency against the Afghan government in a string of attacks that have killed civilians, Afghan forces and U.S. military personnel.

Between the University of Washington, a thriving tech community, and strong research institutions, like the Allen Institute for Artificial Intelligence (AI2), many of the rapid developments in AI are playing out in Seattle. Perhaps that's why the White House has selected the Emerald City for its first public workshop on artificial intelligence. The Office of Science and Technology Policy will co-host the first of four events on artificial intelligence at the University of Washington May 24. The workshop, put on by the UW's Tech Policy Lab and School of Law, will explore issues such as policy, logistical applications, and safety, as they relate to AI. Speakers include AI2 CEO and UW Professor of Computer Science and Engineering Oren Etzioni, White House Deputy U.S. CTO Edward Felten, Microsoft Principal Researcher Kate Crawford, and other industry experts. The workshops are intended "to spur public dialogue on artificial intelligence and machine learning and identify challenges and opportunities related to this emerging technology," writes Felton in a White House blog post.

Sabrina Knight's second-grade students at a Brooklyn public school receive lessons in coding. Some school districts in the United States are attempting to expand computer science education while the Obama administration is pushing to bring the subject to every public school in the nation. On a recent Friday afternoon at a Brooklyn public school, the children of Sabrina Knight's second-grade class listened intently as she used a peanut butter and jelly sandwich to talk about algorithms. Moments later, a student volunteer walked back and forth across the room to demonstrate looping, a technical term used in the field of computer programming. "Thumbs up if you got it," Knight said, as a flurry of 7- and 8-year-old hands and thumbs shot up in the air.

Google this week announced a new messaging app with strong encryption, meaning that your communications can't be wiretapped. But there's a catch: You have to turn on that feature yourself. The tech titan's plan to launch Allo this summer without encryption by default has drawn withering criticism from some quarters. Google's decision to disable end-to-end encryption by default in its new #Allo chat app is dangerous, and makes it unsafe. "I, too, would prefer that Allo be encrypted by default," said Kevin Bankston, director of New America's Open Technology Institute.

These last few months have presented some complicated security stories, and this week we took steps to untangle them. We looked at the many, many ways in which the FBI hacks people, revelations of which have been trickling out for decades. And we broke down just how hackers were able to lift 81 million from a Bangladeshi bank in a matter of hours--well short of their billion-dollar goal, but still a hefty sum, cleverly obtained. In the world of software, Google has finally offered end-to-end encryption in its messaging products. It's Allo and Duo, new chat and video apps that use the stalwart end-to-end encryption known as Signal. On Allo, end-to-end kicks in only when you're in incognito mode, which we guess is better than nothing.
