      Actually, it's a hardware RNG feeding the instruction, and in Broadwell there are two instructions, RdRand and RdSeed. RdRand for an often (2 million times a second) reseeded SP800-90A compliant AES-CTR-DRBG. RdSeed for an XOR construction ENRNG built about the DRBG using the AES-CBC-MAC conditioner output for the full entropy seed.

      I thought everyone knew that.

      And what's more the pseudo random number generator is NSA approved.

      No. In designing it, I plotted a path around the obvious back doors in SP800-90 and FIPS140-2. I don't think the part of the NSA that likes weak RNGs likes that one. The obvious back doors being the Dual-EC-DRBG and FIPS140-2 section 4.9.2, which I call the FIPS entropy destroyer.

      The reseeding 2 million times a second thing is an effective defense against a class of hypothetical attacks which wouldn't work anyway.

      It is FIPS compliant, but we won't be claiming FIPS certification until it is actually FIPS certified.

    My colleague is a Linux Zealot. I use a Mac. I am at least 2.5-3 times more productive than he is.

    Linus Torvalds is much more productive than you. He uses Linux. You should definitely switch.

    Seriously, my car also costs 15 times a much as my bike but it also gets more done.

    You're not coming across as a "different tools for different jobs" kind of a person. This makes me inclined to believe that you're the zealot not your coworker. Bikes and cars do not fit in the same categories and neither is a replacement for the other.

    Also, my Macbook Pro is 7 years old and looks like new.

    And here we have the crux of the Mac v. Linux argument.

    Well not really. I'm not the kind of person who believes that CPU speed is the only spec that matters,

    A 7 year old machine is getting quite long in the tooth. At 7 years old, compared to a new machine, it will be slow, limited RAM, heavy, have a completely usless spinning optical drive, a slow, spinning hard disk near the end of its servicable life on the end of a slow SATA link almost certainly an ageing battery and by modern standards a rather anemic sceen resolution and the backlight will be faded out considerably. And it will be heavy too.

    At 7 years on it won't be a good machine in any regards, unless the author has spent a good deal on upgrades in which case it's hardly a 7 year old machine and substantially more expensive too.

    Also, I frankly don't believe the author that it "looks like new" unless he's never used it as a laptop (i.e. carried it around). Cases (even metal ones) get scratched. Keys get dirty because even clean fingers have grease on. Things get worn if they're exposed to the environment. And if it hasn't been, well, my that's a pointless statement since anything untouched will look like new in 7 years except food.

    Out of the box rt YAHOO. Let the games begin...OR more to the point for those who could care less about gaming but record music, stream transcoded AV and do serious studio work LINUX will knock it out of the park! Provided ALSA, THE PULSE MONSTER, Rosegarden, Audacity, Ardour retool to use the rt headers correctly so the linux install does not have to have a hacked up security_limits.conf and a patched kernel. HALLELUJAH I say. Mind you one still might have to increase the frequency from stock 250 to 1000 for their install. Modern systems with higher bus speeds should handle this change but it might not sit to well on slower older hardware like a year 2000 P111 or older.

    I have been running rt since the early days and have always felt like having to tweak a kernel just to obtain low latency was a road block for the future of Linux.

    Further to your points about the stylish mac users comments right now I am running Mint 16 DEBIAN on an IBM T42 from 2005. It has 1.5 meg of ram a long in the tooth 48 meg onboard radion 7500 vid. The processor is not even pae for crying out loud and I can still run GOOGLE EARTH 6 .386 AND SPIN THE GLOBE ON LINUX WHILE I POST THIS DITTY RUNNING SPINNING GLOBE ON A SECOND DISPLAY FROM THE VGA PORT.

    The nine cell aftermarket battery still gets me 4-6 hours depending on air time with the agb wireless. MIND you I only do this at a maximum 1024x768 as I write music notation or whatever on this little gem of a computer with Open Source Software or do whatever kind of correspondence in any file format you want. PDFs, XLS, .DOCX it does not matter I can create it all effectively with several different pieces of software, heck I can even transcode short .MOV vids in 720p on this little gem without taxing the proc too much

    EAT YOUR HART out Windows and MAC users. I am not kidding... LINUX IS GETTING THAT FAR AHEAD OF YOU. And with the addition of stable 3.14 RT kernel out of the box it will only get better.

    And that is the beauty of Linux in general the more you keep up with the Jones' Apple and Windows users sell off your old 'puters dirt cheap the better Linux gets! OUT OF THE BOX with Linux this little laptop (tm)Linux Just Works with a well done nonpae capable distro. Of course if you do not understand what I just posted take off your glasses and read it carefully for it is the truth. Linux users can do stuff with older hardware that you can without paying a frigging fortune to do it!! And that is why helping out the people who build OSS like Linux is a great thing. PERIOD EOF

    Above post proves that some persons are willing to pay a lot more for the same tools as those who use the best practices of resource management.

    And that some people cannot make the distinction between effective workflows and good tools.

    It is easy to be inefficient on a Linux box. Move that user to a Mac or Windows box, and a strange thing happens. He will be just as inefficient when measured by time. However he will be much more inefficient when measured by total cost of his output.

    In conclusion, the easy way to increase the inefficiency in a workflow is to buy expensive computers for the most inefficient personnel. This stimulates the economy. The cost of this stimulation is borne by the companies that use this tactic and shows up as a decrease in competitive advantages. But it is all done for the greater glory of Apple and Microsoft so it is all good.
