Computer technology: State of the art and future trends
Computer technology and, more broadly, information technology, are bringing about a fundamental transformation in our society from an industrial economy to an information economy. A review of the short history and present state of information technology identifies two major undercurrents: I) the miniaturization of computer components, which has produced a millionfold increase in the complexity possible in a single chip of silicon, and 2) the integration of four previously separate areas of information technology: computation, communication, databases and the user interface. Microelectronics, computer networks, data storage and user amenities are the basic technologies that support these four areas and stimulate their progress. Future trends in speech recognition, voice synthesis, artificial intelligence, expert systems, computational imaging and scientific workstations are also examined.

SpaceX Achieves First Successful Rocket Landing at Sea
After SpaceX's previous attempts to land a rocket at sea ended in failure, the company successfully landed its Falcon 9 rocket on Friday afternoon on a landing platform in the Atlantic Ocean.
It was a historic landing of a rocket's first stage soon after it launched, and congratulations poured in from around the globe, including from President Barack Obama, who tweeted "Congrats SpaceX on landing a rocket at sea. It's because of innovators like you & NASA that America continues to lead in space exploration."
After its launch at 4:43 p.m. Eastern time, the 14-story-tall booster used its remaining fuel to reenter the Earth's atmosphere and touch down on an unanchored "droneship" in the middle of the Atlantic.
"It's another step toward the stars," SpaceX founder Elon Musk said at a press conference afterwards, according to the Washington Post. "In order for us to really open up access to space we have to have full and rapid reusability."
SpaceX has successfully landed the Falcon 9 rocket on land several times. But achieving a sea landing is important because such landings will almost certainly be necessary for future missions when vessels returning from farther celestial destinations like the moon or Mars approach the the Earth at high velocities.
Today's launch used SpaceX's Dragon spacecraft to bring supplies to the International Space Station. It was filled with about 7,000 pounds of critical supplies and payloads for the space station crew, including materials to support research and scientific investigations. The Dragon capsule itself will return to Earth in about a month, when it will splash down in the Pacific Ocean off the California coast.
Popular Firefox Add-Ons Vulnerable to Cross-Extension Exploit
Here's the bad news: There's a new kind of browser attack that can take advantage of the normally helpful things that some of your extensions can do. It's actually a rather ingenious attack. Rather than trying to infiltrate your browser and having it do something it shouldn't, a malicious extension attempts to get your other extensions—which aren't isolated from one another—to do things on its behalf.
The end result? It's trickier to find the original attacker, since it's basically hiding in plain sight. And this isn't just an issue that affects lesser-known extensions. As researchers from Boston's Northeastern University found, nine of the ten most popular Firefox extensions could be exploited by another extension—one that appears to be totally benign and normal on its face, but is piggybacking off of other extensions to steal a user's personal data or redirect them to malware-filled websites
"These vulnerabilities allow a seemingly innocuous extension to reuse security-critical functionality provided by other legitimate, benign extensions to stealthily launch confused deputy-style attacks. Malicious extensions that utilize this technique would be significantly more difficult to detect by current static or dynamic analysis techniques, or extension vetting procedures," reads a paper from said researchers, presented at Singapore's recent Black Hat Asia security conference.
Just to show how easy it is for an attacker to exploit these vulnerabilities, The Register reports that the researchers were able to upload a blatantly malicious—but harmless—extension to Firefox's big gallery. The extension, dubbed "ValidateThisWebsite," didn't conceal its ambitions in its code whatsoever. And, yet, the extension still managed to make it through Mozilla's security checks, even a more extensive "fully reviewed" analysis, without issue. (That's likely because it's not making any malicious calls to Firefox itself; it's making other extensions do it once it's installed in a user's browser.)
Said researchers provided Firefox with an explanation of the process as well as a new Crossfire application that can assist with finding these sneaky extensions. Firefox vice president of product, Nick Nguyen, also issued a statement that indicates Mozilla is actively working to secure up extensions and eliminate these cross-extension vulnerabilities.
"The way add-ons are implemented in Firefox today allows for the scenario hypothesized and presented at Black Hat Asia. The method described relies on a popular add-on that is vulnerable to be installed, and then for the add-on that takes advantage of that vulnerability to also be installed," it reads.
"Because risks such as this one exist, we are evolving both our core product and our extensions platform to build in greater security. The new set of browser extension APIs that make up WebExtensions, which are available in Firefox today, are inherently more secure than traditional add-ons, and are not vulnerable to the particular attack outlined in the presentation at Black Hat Asia. As part of our electrolysis initiative—our project to introduce multi-process architecture to Firefox later this year—we will start to sandbox Firefox extensions so that they cannot share code."

In a milestone for artificial intelligence, a program designed to play the ancient Asian game of Go has won the first of its five games against a human champion. It's an example of how smarter software, not just more powerful hardware, will drive progress in the computer industry in the future
