    good applicaiton of combining Motion + PageKite + gnome-screensaver-command.
    btw, one character “&” missing after the first line the script–motionlock.sh

    Hi Foks,
    The md5 collision is only theoretical. But is is best to use SHA1 or higher.
    To find out if you have other hash functions in Linux at the command prompt type:

    info coreutils

    Scroll down to:

    Summarizing files

    * wc invocation:: Print newline, word, and byte counts
    * sum invocation:: Print checksum and block counts
    * cksum invocation:: Print CRC checksum and byte counts
    * md5sum invocation:: Print or check MD5 digests
    * sha1sum invocation:: Print or check SHA-1 digests
    * sha2 utilities:: Print or check SHA-2 digests

    My systems has sha1sum and sha2.
    Hopefully the system that you put your password into will also run a hash function.

    Darren’s idea shounds good to me. salt + password + hash function.
    You could also put the salt at the front and end. salt + pw + salt + hash.
    Use different dns queries for the first and second salt.

    Can any one improve on this idea?

  • hello,

    what is the file size of the 720p30fps latest edition of hak5. i have

    but it cuts off during the arduino segment.

    There’s a problem with the HD version of the video. It looks like it got cut off in editing. Other users have commented on this at Revision3, as well.

    In response to the issue having a function run on unlocking Ubuntu, if you use xlock, you may be able to use the following as your lock function:

    /user/bin/xlock -endCmd ` `;

    Unfortunately, I’m not currently able to test this, but it should work.

      Oops, WP stripped part of the command. Put the code you want to run between the graves (ticks).

    You named your cat Luna? Are you a brony?

  • When I saw the title for this, I thought it would be for locking your computer when you stepped away from it. That would be kinda neat. A little excessive.. leaving the camera on the entire time you are using your computer. Still might be a cool proof-of-concept.

    Just thought to share! Thanks!

    Hi everybody
    I recently made an app for reset Cards plus more management tools for mifare cards. I tested it and it is working without error with all types of mifare cards. I suggest you to download and test it by following link form google play.
    https://play.google.com/store/apps/details?id=com.omegasoft.NFCUltraTestonly
    Or you can find it by its name in your phone store. Its name in your phone store is: “NFC Ultra Ticket Resetter”
    If you download the test project it is free.
    Please let me know your comments
    thanks
