  1. Re:i can smell Rajs bullshit from here on Firewall Company Palo Alto Buys Stealthy Startup Formed By Ex-NSAers · · Score: 1

    There's something that calls itself 'Princeton Alumni Weekly' that lists Raj Shah as a F-16 fighter pilot.

    CEO of Morta Security. Strong business (McKinsey, private equity) and government (@USAF F-16 pilot, DoD, NSA) background. @Wharton MBA, @Princeton undergrad.

    Yes, by law, the Brazilian equivalent of the IRS (literally, Federal Revenue Secretariat) has the right to inspect shipments at border control points. Sometimes they inspect, sometimes they don't. You usually get a note in the mailbox 'Your package is awaiting for collection at XYZ street, import duties R$ (obscene number here) must be paid'.

    The only thing this is meant to accomplish is allowing the current administration to pose as being interested in protect some sort of "national sovereignty" and transferring some cash to government contractors - the standing Party needs cash to finance it's next run for the presidency. The half dead state owned phone company, Telebras, still exists despite having no customers. The government would finance the new cables, Telebras employees would get their kickbacks and funnel money into shady government contracts. Politics as usual with a little antiamericanism sauce.

    A common factor in almost all Brazilian corruption scandals is that somehow the media gets access to "secret" telephone conversations: the country is already bugged (legally sometimes) by the Federal Police and (always illegally) by the Brazilian Intelligence Agency. It's not uncommon for the administration to leak data from legal and illegal bugs to pursue adversaries. It's scarily common and rarely protested by the general populace.

    It disgusts me.

  9. Re:A great win for FreeBSD on PlayStation 4 Will Be Running Modified FreeBSD · · Score: 1

    XNU, the kernel that powers OS X, is a hybrid derivative of both Mach kernel and of the 4.3BSD kernel.

    Originally developed by NeXT for the NeXTSTEP operating system, XNU was a hybrid kernel combining version 2.5 of the Mach kernel developed at Carnegie Mellon University with components from 4.3BSD and an object-oriented API for writing drivers called Driver Kit.

    After Apple acquired NeXT, the Mach component was upgraded to 3.0, the BSD components were upgraded with code from the FreeBSD project and the Driver Kit was replaced with a C++ API for writing drivers called I/O Kit.

  10. Re:It's ironic... on GNOME Aiming For Full Wayland Support by Spring 2014 · · Score: 2

    Older X11 application (like those built on Motif) are like that. They send a stream of primitives, so they're easily used over a network. But modern applications (like those built on Qt and GTK) use X11 as a screen buffer and instead of using X11 primitives, they just send large bitmaps to the X11 server. So modern X11 applications sucks when used over a network but older ones actually works fine.

  11. Re:Forcing old world views on the new world? on Bruce Schneier: A Cyber Cold War Could Destabilize the Internet · · Score: 5, Insightful

    Is it not completely possible that one intelligent man, $300 laptop, and an internet connection be just as "deadly" as any country's electronic warfare unit?

    A large organization such a national electronic warfare unit is able to perform more target attacks: obtaining information about the target systems using other means such as human intelligence, coordinating a large team with multiple specialists (an exploit guy, a SCADA engineer, ...), being able to use again human intelligence to infiltrate the target, like bribing a guy to run a software from a USB drive or something like that.

    While a single individual might be able to pull a highly targeted attack, it is considerably easier to a large organization to have the necessary budget to hire different specialists, coordinate with other agencies to leverage their resources, and so on.

  12. Re:Seems easy on Moon Mining Race Under Way · · Score: 1

    There are two very different sets of requirements whether you need to cross or not the radiation belts. For low earth orbits, COTS equipment is fine for a short mission. For higher orbits, including direct lunar transfer or a Hoffman orbit transfer, radiation hardened equipment is a must.

    Also the Android-running cubesat (by Surrey U (UK), not NASA, if I recall correctly) is just a inexpensive cubesat mission (under 50 or 60k USD, including launch costs) not an expensive lunar lander.

  24. Re:Really? on World's Largest Biometric Database · · Score: 3, Informative

    Iris scanning actually works in a way similar to a hash. You take the iris picture and find a 2048-bit number, the "IrisCode" or wherever you wanna call it. If you want to make a comparison, then you find the IrisCode for the other picture, and compute the Hamming distance between two. The threshold for match or no-match is actually a function of the database size. (I read the paper a while ago and I'm probably made a few mistakes describing it, but it works along those lines). John Daugman site has more details.

    A "HUMAN_IRIS" is just a 2048 bits field. Read about IrisCode (pdf warning) some time. It's a really elegant solution.
