  • Zuse

    Great Episode!!!…
    FYI: the voting on this page (or on any page) does not work, it just says “please wait…” when you click on it. This has been broken for a long, long time on your website…
    please see if you can fix it.

    James, vipw or vigr are two programs that help to manually modify the /etc/passwd and /etc/group files so that you don’t make a mistake and break your system. It performs a sanity check when exiting to make sure the file is formatted correctly.

    What is the deal with the recent episodes of Hak5? They have become Darren pretty much conducting the episodes like a boring college lecture. It’s just him writing on the table with markers and Shannon saying “Ooooh Oookkk”. You would think the host of a Tech show would be teaching the audience… not one host boring the audience while teaching the other host! Used to be a big fan…..

    You forgot to mention in order for this to work the box you are connecting to must have internet connection to check key. Carefull guys this won’t work on a isolated box.

    Okay, so I was watching this episode and started thinking of a way to make secure password.

    What not use time in the maths.

    like this:

    Password: 0001
    maths= x5 -4 x%time%= %password%

    time could be anything that is the current time, the date or both.

    i.e. 11:59:22 – Hours:Mintes:seconds or 05:04:2012 month:day:year or both 11:59:22:05:02:2012

    I really hate to think what that number might be, but you’d leave out the ‘:’ and just go with numbers, since the first lot would only need to be in two’s and the last would be four.

    Wait this is a stupid idea, right?

    Why not use those coupons for getting your selected healthy
    products. Internal motivation is linked to neurological circuitry in the left prefrontal lobe; the
    feelings of accomplishment, adoration for work, excitement
    inside our day all connect to the left prefrontal cortex.
    It will need around 7-10 days to complete a cleanse and
    results may start to become noticed inside the first three days.

    Dieting will be the nastiest word within the world of,
    well, dieting. Now everything is a lot easier due to coming of people diet pills.

    Every time I have tried to go “all in” at the same time, I wind up losing,
    whether in Vegas or wanting to stay away from my neighbors BBQ.

    Hi there! I know this is sort of off-topic but I had to ask.
    Does managing a well-established website like yours take a massive amount work?
    I am brand new to running a blog but I do write in my journal daily.
    I’d like to start a blog so I will be able to
    share my own experience and thoughts online. Please let me know if
    you have any recommendations or tips for brand new aspiring
    bloggers. Appreciate it!
