Der Spiegel has published today an excellent summary of what some of Edward Snowden's revelations show about the difficulty (or, generally, ease) with which the NSA and collaborating intelligence services can track, decrypt, and correlate different means of online communication
. An interesting slice: The NSA and its allies routinely intercept [HTTPS] connections -- by the millions. According to an NSA document, the agency intended to crack 10 million intercepted https connections a day by late 2012. The intelligence services are particularly interested in the moment when a user types his or her password. By the end of 2012, the system was supposed to be able to "detect the presence of at least 100 password based encryption applications" in each instance some 20,000 times a month.
For its part, Britain's GCHQ collects information about encryption using the TLS and SSL protocols -- the protocols https connections are encrypted with -- in a database called "FLYING PIG." The British spies produce weekly "trends reports" to catalog which services use the most SSL connections and save details about those connections. Sites like Facebook, Twitter, Hotmail, Yahoo and Apple's iCloud service top the charts, and the number of catalogued SSL connections for one week is in the many billions -- for the top 40 sites alone. ...
The NSA also has a program with which it claims it can sometimes decrypt the Secure Shell protocol (SSH). This is typically used by systems administrators to log into employees' computers remotely, largely for use in the infrastructure of businesses, core Internet routers and other similarly important systems. The NSA combines the data collected in this manner with other information to leverage access to important systems of interest.Read Replies (0)

writes Spaceflight has faded from American consciousness even as our performance in space has reached a new level of accomplishment. In the past decade, America has become a truly, permanently spacefaring nation. All day, every day, half a dozen men and women, including two Americans, are living and working in orbit, and have been since November 2000. Charles Fishman has a long, detailed article about life aboard the ISS in The Atlantic that is well worth the read; you are sure to learn something you didn't already know about earth's permanent outpost in space. Some excerpts:
"Life in space is so complicated that a lot of logistics have to be off-loaded to the ground if astronauts are to actually do anything substantive. Just building the schedule for the astronauts in orbit on the U.S. side of the station requires a full-time team of 50 staffers.
Almost anyone you talk with about the value of the Space Station eventually starts talking about Mars. When they do, it's clear that we don't yet have a very grown-up space program. The folks we send to space still don't have any real autonomy, because no one was imagining having to "practice" autonomy when the station was designed and built. On a trip to Mars, the distances are so great that a single voice or email exchange would involve a 30-minute round-trip. That one change, among the thousand others that going to Mars would require, would alter the whole dynamic of life in space. The astronauts would have to handle things themselves.

writes As a power user, you notice certain things that the average person might not. One of those is the difference between typing on a sweet mechanical keyboard with luxurious key action, versus pounding away on a run-of-the-mill squishy plank that relies on membrane switches to register your keystrokes. The difference may seem subtle to the uninitiated, though even casual typists can recognize that there's something inherently superior about a mechanical keyboard. Of course, it's the mechanical key switches that are responsible for elevating the typing experience. These are better than the rubber domes found in membrane keyboards in a number of ways, including feel, responsiveness, and durability. Mechanical keyboards are growing in popularity, as word is spreading about how good they are. In turn, keyboard manufacturers have responded by feeding more mechanical models into what was once a niche market. If you go out in search of a mechanical keyboard, you'll now find a mountain of options. This roundup further reinforced something we've known for a long time, which is that mechanical keyboards are the superior choice for both gaming and daily typing chores. That doesn't mean they're all created equal — there are different key switches to choose from, and features vary from one plank to the next. The choice of key switch type is highly subjective but we can say that Cherry MX key switches are indeed of higher quality than knock-offs like the Kailh switch. That's not to say Kailh switches are bad, just that you can discern a difference when going from one to the other.Read Replies (0)

Convicted drunk drivers all over California may soon be required to install and pay for the use of ignition interlock devices
, at a cost of $50-100 per month, plus installation. Says the article: "State Sen. Jerry Hill, D-San Mateo, wants to expand a program already in place in four California counties, including Alameda, and 24 other states. Under the proposed state law Hill will introduce Monday, anyone convicted of driving under the influence would be required to install an ignition interlock device in their car for six months on a first offense and a year on a second conviction."
Though interlock devices could be fitted to check for other conditions as well, the usual case (as described on this Wikipedia page
) is that they base the ability to operate a car on blood alcohol content. Already in California, interlock devices are mandatory for those re-arrested for DUI while "driving on a suspended license due to a DUI conviction."Read Replies (0)

An anonymous reader writes The MeArm is a flat-pack robot arm. It has been developed in a very short time frame as the creators have been able to tap into crowd development by open sourcing all of the designs. Because of this it's exploded around the world with builders on every continent (bar Antarctica) and there are even people manufacturing them to sell in Peru, Taiwan and South Africa. MeArm manufacture them in the UK and export to distributors around the world, including Open Source pioneers like Adafruit and Hackaday in the USA. They're currently running a Kickstarter for a controller to take it out of the 'Hackersphere' and into the living room. They doubled their target in the first week and are still going strong so it's looking like they will be the first consumer flat pack robot kit in the world!
Controller or not, you can download the arm from Thingiverse
, and follow the project at Hackaday
