  1. Re:Easy to say on Boeing Touts Fighter Jet To Rival F-35 — At Half the Price · · Score: 3, Insightful

    The F-22 hasn't been flown because we haven't been involved in a conflict where air superiority was a requirement of the mission. If/when that happens, like in a conflict with Russia, China, Iran, or...who knows, Germany could go all batshit crazy again and start invading other countries, the F-22 will be used.

    As for the F-35, it's not flying combat sorties yet, because it's still in the testing phase. In another couple years, once it's ready, it will more than fulfill the roles it's intended to fulfill.

    Of course it will -- because it's operating specs keep getting downgraded to match the capabilities of the plane. When the specs get reduced to "Must park on runway with its nose pointed in the general direction of the enemy", then it will be in full compliance with its required specs.

    If the current operating specs were put out to bid today, what would the proposals look like?

    Amazing you havent learnt the strange habit of waking up 2 minutes before the alarm is due to go off , simply so you can turn it off before it rudely shocks you awake?

    The dog usually wakes me up a few minutes before the alarm goes off (not on purpose of course, she's just poking me in the face with her cold nose to see if maybe I'm already awake), but whether you wake up before the alarm or not, you still have to turn it off. And it's easier to turn it off while the alarm is sounding since the "Off" button is right on the screen - no need to unlock it and then navigate to the alarm app.

    If your alarm is shocking you awake, you should try a different alert tone, mine starts softly and gradually gets louder so I can turn it off before it wakes my wife. I haven't been shocked awake by an alarm for at least a decade when I got a Sony Dream Machine alarm clock that gradually increases the volume of the alarm.

  3. Touching glass morning/night is Nothing new on Sergey Brin Says Using a Smartphone Is 'Emasculating' · · Score: 3, Interesting

    Touching an inanimate object made of glass and plastic each morning and night is nothing new -- well before the days of smart phones (or even cell phones at all), I used to have a manual alarm clock that I'd have to set each night and turn off each morning. So this "strange intimacy" with our gadgets has been going on for 50 years or more.

    Since it was a 12 hour clock, it wasn't possible to reset the alarm when it went off at 7am in the morning or else it would go off again at 7pm, so one had to set it each night.

    Now my smartphone is my alarm, and it's better in that I don't have to set it at night, but it's still the first thing I touch in the morning since I have to stop the alarm.

    There is very little to learn. We already had ground simulations of the flight, and they were generally unsatisfactory. Humans cannot sit in a tin can for two years and retain sanity. That alone overwhelms all the other issues, of which there are many

    Russia, the EU and China conducted a joint simulation with mission lengths of 15, 105 and 520 day durations. After the 520 day mission:

    http://en.wikipedia.org/wiki/MARS-500#Experiment_stages

    The 520-day final stage of the experiment, which was intended to simulate a full-length manned mission, began in 3 June 2010 and ended on 4 November 2011.[8][9][10] This stage was conducted by a six-man international crew, consisting of three Russians, a Frenchman, an Italian/ Colombian and a Chinese citizen.[10] The stage included a simulation of a manned Mars landing, with three simulated Mars-walks carried out on 14, 18 and 22February 2011.[11][12] The experiment ended on 4 November 2011, with all the participants reportedly in optimal physical and psychological condition.[10]

    In January 2013, the Proceedings of the National Academy of Sciences reported that four of the six crew members had considerable problems sleeping, and some avoided exercise and would hide away from the others, in behaviour compared to animal hibernation.[13]

    Insomnia and exercise avoidance doesn't sound all that unsatisfactory. Though I don't think it's possible to truly simulate a mission to Mars here on Earth when the participants know that if things go very bad, they are just an escape hatch away from help. I think the only way to do a true simulation would be if the participants really thought that they were in a space capsule, which is pretty hard to do when gravity gives it away.

    They had 6000 volunteers for the long mission - I suspect that an actual mission to mars will result in many more volunteers, despite the risks.

    Build an automated city on Mars first. A habitat is needed so that people can land there and have something waiting. It would be even better if the automated city were busy harvesting water and splitting it into H2 and O2 for the return trip.

    If you want to fund an automated city on Mars, go for it - build a compelling case and shop the idea around to some billionaires and see if you can get it funded. That's probably easier than getting politicians to give NASA enough funds to do it.... or worse, trying to build an international coalition of national space agencies to do it.

    IMHO, the tech for exploring Mars has to come from the mining industry. Yes. Mining. Start with ultra-automated mines on Earth. Then, Mars-adapt that technology and send it there. Ditto for construction. Come on miner/builder-bots guys, build us some Mars bots and get 'em on the job.

    I don't know if you've seen earthbound ultra-automated mining but it's typically built of very heavy steel, not something you can easily get to Mars until asteroid mining is available (and this research is in-progress). Mines on earth of more interested in replacing human labor with machines so use big machines to process large quantities of materials.

    It's right there in the article:

  10. Hardware encryption offers superior security to software encryption. That said it's not easy to generate entropy so if you do use software encryption you better have a source of entropy.

    Hardware encryption is only superior if you (or someone you trust) can inspect the software.

    For all you know, they use your passphrase to decrypt an hardcoded decryption key that's the same on all drives, so if you put your hard drive into someone else's enclosure, their passphrase will decrypt your data.

    While I don't think they are doing anything so blatantly stupid, unless you can see the software, you don't know. A number of big-name "secure" USB drives had a big security flaw that was almost exactly like that.

    Anologue is better than digital. Hardware is better than software. Also you have to read about and study the hardware fairly well before choosing the product. Those products you list all suck. The Aegis Padlock Pro does not have those problems by design.

    But how do you know that? Were you sitting in on the design meetings?

    For all you know, Aegis gave a list of back-door decryption keys to the Department of Homeland Security, just in case they need to access a terrorists drive. Maybe next year you'll be saying "Aegis products suck, their drives were full of back doors". Maybe Aegis is just a shell company run by the NSA to make people think that they are buying "secure" drives, but in actuality they are easily read by the government.

    I have more faith in open source software because even though I'm not a security expert and can't validate the software myself, I trust that there's no global coalition of open source security software experts that are are all conspiring to steal my data - if there's a vulnerability in the code, it will be found and can't be kept secret.

  11. Re:Hell no on RSA: Self-Encrypting USB Hard Drives for all Operating Systems (Video) · · Score: 1

    Truecrypt is a software encryption implementation. Hardware encryption is superior to software encryption because at least with hardware encryption there is less room for error. Software usually has bugs, one bug in any implementation and its broken. Side channels also can defeat software trivially. Software also isn't usually good at generating entropy so you wont have a good source of that either. Unless you compiled it yourself you can't trust the person who compiled it or the compiler itself not to have a bug or backdoor.

    Just because it looks like "hardware" doesn't mean that it's not software - I'm certain that this device isn't running on a hardwired FPGA, so it's running software. Why don't you trust software compiled by someone else, but you trust software hidden away in a hardware device that's been compiled by someone else?

    The difference between hardware and software is that when the software embedded hardware is broken, it's not always possible to fix it - not all devices allow firmware updates.

    You keep mentioning entropy as a big weakness of software, but there's no evidence that this device has a hardware random number generator (and why would it for an event that takes place maybe once in its lifetime), so it gets entropy the same way your computer does. By combining data from a number of "random" sources (hardware clock, timing hardware interrupts, etc).

  12. Encryption software needs to be inspectable and verifiable in order to be trusted with anything worth protecting. Closed-source software burned into the firmware of a USB drive does not meet that requirement.

    That said, somebody make a programmable USB drive with open source encryption that can be flashed to it (probably with a fused write protect) and *that* would be a compelling product.
