  1. Re:You are correct, but on Can We Travel To That Exciting New Exoplanet? · · Score: 1

    It probably makes more sense to increase the the thrust to go from 1.0 to the maximum save limit over the months of travel and then on the slow-down stop at the level of the target planet. If you're talking about periods of some sort of deep sleep while traveling, a few more Gs are probably ok while everything is strapped down. You just need a propulsion system that can alter the thrust quickly.

    At the moment, there are still too many numbers. ID card number, passport number, maybe a driver's license number, a tax number for every state you worked and lived, etc.

    But they are already working on a unified number that you get at the time of your birth and that will stick with you until you die.

  5. Re:A little bit of perspective... on Germany To Roll Out ID Cards With Embedded RFID · · Score: 2, Informative

    You have to actively go out, apply for an ID card and pay the fee to get one. You can live a long and productive live and never use your ID at all, unless you're a lawyer by profession or get arrested a lot...

    Not quite. You will have to use it if you want to get a bank account (and I assuem you want one). If you're younger, you will have to use it to get a driver's license, probably to sign contracts, to get into music clubs late night, to get alcohol, even to play the lottery and of course everytime you fly within the EU.

    So I say you can live a long and productive live alone in the mountains and never use your ID at all.

    There were plenty of choices even "at the end" for those slots.
    C= always provided the basic cards and GVP and others provided the more featureful cards.

    That was more than the whole PC sector at the time managed to produce. All PC CPU upgrades were pathetic ("Intel overdrive", to name one from the strongest vendor in the industry).

    Can't remember those in the IBM XT. You remember the 68030 CPU/mem expansion card from C=? Even the expansion card was expandable! (Years later with 100 times the memory of the original computer).

  14. Re:RAM error? on Tracking Down a Single-Bit RAM Error · · Score: 1

    A few years ago I noticed that a file on a disk (probably Windows) had a slightly changed file name (one character was different). I checked and the character was just one bit off the one it should have. Of course I don't have proof the disk was at fault. I'm sure anything inside the disks is protected. Most likely the "disk errors" are just memory errors written back to the disk.

    I interviewed some current master's students and was optimistic until it was clear that they did exactly what coursework required but weren't interested in exploring for their own interest.

    I think this is important. If people apply to be a UNIX app support engineer in the year 2010 at the age of 30 and never came across Linux or and never used any Unix at home before, then there is something wrong. I'm not saying you can't be good at your work and never bring it home. But the chances are high you will never love your job if you never even thought about doing something similar in your own time. Or someone studying Computer Science/Engineering without owning his own computer at home until the second year. For some reason this case actually turned out pretty well, but chances are low. Maybe it's like someone applying for a job as a mechanic because he has heard it can be an interesting job, but never done any mechnical work until the age of 30.

    *Yes, walking does create wear-and-tear on the sidewalks, but such wear is minimal and businesses located along the sidewalk would pay to have them built as it would benefit their customers.

    I think this scheme is already quite common (in Germany). We pay the city for cleaning the part of the road in front of our house, we pay for the amount of household rubbish we produce, we pay a fee when visiting the doctor or getting a better tooth repair, we pay a yearly fee for using libraries if we want to use them, we pay for using city-owned car parks, we (may) pay (per mile) for using the Autobahn (eventually), we pay to get rid of special waste. I could go on forever. All this could (and probably was in the past) be for free and paid through taxes. So I'm pretty sure we're going in the direction you're describing. The only problem with that is: You will also need to pay for services which should be for free, like the libraries I mentioned. You're actually discouraging poorer people and kids to read. Not a smart move. Now people with enough common sense an money donate yearly library subscriptions to kids. Strange new world.

    That's the way the conversion works, and as you can see, it's very simple to go from there straight into binary. I can automatically convert the bytes into bits in my head too, wanna see?

    1.44(2^23)

  21. Re:Ignore it? on Coping With 1 Million SSH Authentication Failures? · · Score: 1

    Also, you're right - a "system' for your password will definitely decrease security, no question about it, since any system is by definition non-random.

    The most hilarious "system" I've ever seen was this one (about 10 years ago): root password is the servers hostname plus a random number.
    Worked especially well if you happened to choose servers names with 8 characters or more.

    (I guess nowadays Unix/Linux systems often use more than 8 characters for the password. Check your /etc/shadow for MD5 and alike hashes.)

    key-auth should be sufficient. The probability of guessing user name and the key is so absolutely remotely that 1 million login attempts do not get you any closer to it.

    Why do you think the user name would add any difficulty to this? User names are often very short and also easier to obtain by other means.

    So unless you have very secure boxes and different, long, random strings as a usernames for each of them, "guessing the username", will not be a problem.
