Machinimas with iGrabber
02:49:09PM, 19/09/10 AEST-03:10:00PM, 19/09/10 AEST
Remember the iGrabber I mentioned in previous posts? Well, yesterday and today, I've been making machinimas. They are very bad film technique, no audio, and are just for my two little brothers.
They are filmed off Ben 10: Vilgax Attacks for the Playstation 2. Basically, it's me running around killing the alien enemies for roughly ten minutes.
My Playstation 2 is set up in my room, with the three RGA male plugs in the three RGA female sockets on the iGrabber. The video streams live onto my laptop and I record it (I'm still trying to fix the audio feed). Then after say ten minutes I stop recording, edit the video (brush up frame rates, mute audio-because instead of the game's audio it's my laptops microphone). Then, I burn it onto disc and play it for them on the Television.
So the iGrabber is a very useful device, for programmers, machinima enthusiasts, etc.

Unreal Development Kit
06:26:16PM, 14/09/10 AEST-06:49:40PM, 14/09/10 AEST
Many of you might have heard of the Unreal Engine (mainly those of you who are programmers, developers, gamers, etc.). Also, you may have heard of the Unreal Development Kit (UDK). Well, I found out about it roughly a fortnight ago.
I was blown away by the graphics on the Sanctum Demo (which I downloaded before the UDK) and it is amazing. Also, the physics components are wonderful. I also enjoyed Bink for video alot.
DirectX 9.0c is the minimum requirement for the engine and the UDK. For those of you who are not aware of what DirectX is, it's and API (Application Programming Interface) for multimedia (graphics, renderings, audio, etc.). For more information on DirectX go to http:\\www.en.wikipedia.org/wiki/DirectX.
The downside to it is the large resources required for the platform.
I do strongly recommend it to you.

Floppy Discs Saved My Research
07:50:00PM, 05/09/10 AEST-08:25:00PM, 05/09/10 AEST
The floppy disc is an almost forgotten technology. However, I think it is a vital role in a developer's OS projects. E.g.
A Tinkernut.com tutorial on OS programming used floppy technology. Mainly for it's multiple "layers" of encoding and storage to allow for bootloading and filesystem storage abilities. He explains that more if you watch this video (http://tinkernut.com/archives/2326).
Also, for some computers that have no working drivers for their USB ports and the CD drive is strangely dysfunctional, the only resort is floppy drives. E.g.
I have an old IBM Aptiva running Windows 98 and all the instruction manuals and all the software intact. I use it to study Windows 98 and technology before registries (see previous posts) and logfiles.
1.44MB IBM floppy discs are what I'm using. for my laptop, I have an external USB floppy disc drive (it's a LaCie one).
So that's why floppy drives and floppy discs should be used a bit more. Not alot...maybe 15% more?
Tell me what you think.

Google Pacman
07:38:40AM, 05/09/10 AEST-09:06:00PM, 05/09/10 AEST
I first got on to this when I googled Google. Some of the results were Google Pacman. Wow I thought, an online implementation of Pacman-by Google?
So I followed it (http://www.google.com/pacman) and started playing. It's a Google logo, yet interactive. Intead of I'm Feeling Lucky it has Insert Coin. Pressing Insert Coin in the middle of a game, will restart and bring up Pacman and Mrs. Pacman allowing two-player co-op.
My highscore is 11760. But, I bet some of you could beat that.
Now, this was a few days ago. Just before writing this post, I had the sudden idea to analyse the game. A Google Chrome extension called Pendule is a web developer tool. It is fantastic, I suggest you try it.
So, I used Pendule to analyse the source code first.
Then, I used the in-built JavaScript Console in Google Chrome (see my previous post entitled Google Chrome Review for more info). I also, did a resource track and the game restarted.
<html onmousemove="google&&google.fade&&google.fade(event)">
Was the beginning tab for the HTML code. Now, I'm not sure what this means, as I haven't studied deep enough into HTML to know (I'm mainly in native development). However, feel free to comment if you know.
This happens quite alot in these types of examinations (especially JavaScript libraries that link into the HTML). That is the fun of it, studing it and learning how to interact with it.
So then, I used the JavaScript console to debug and wow! As I type this sentence (08:59:00AM AEST) there is 455 and growing fast errors of this:
Uncaught TypeError: Cannot read property 'style' of undefined.
So just a matter of seconds after typing that error, I paused the script execution-and the errors stopped growing. I paused it at 834 errors (all the one type, just 834 different instances of them).
Well, I strongly recommend you download the latest version of Google Chrome and install it. Then, go to some interesting site and examine it.
It is very rewarding.

Fixing Stuck Pixels Using Batch
06:25:42AM, 05/09/10 AEST-06:46:10AM, 05/09/10 AEST
Stuck pixels are generally just a jam in the LCD display. They can be fixed many different ways and in this post I'll show you how to do it using a batch file.
Now, step one, open up your text editor (mines Notepad) and enter this code:
:LOOP
@echo off
@color 53
@color 23
@color 35
@color 32
goto LOOP
Now, an explanation. :LOOP is the name of our subroutine. @ echo off turns on the echo function (I just put it in their it's not required). @color displays a color (which one depends on the number after it). Then finally, goto LOOP executes the LOOP subroutine.
This code will be an infinite loop (not really but theoretically). So, save it as whatever you like but end it as .bat filetype. Then execute the batch script and move the window over the area of the stuck pixel(s). Leave it for 5 seconds and then close the program. Feel free to edit the source code as you wish, but leave the colours the same.
Now, if that didn't fix it, try going to http://tinkernut.com/archives/442 and watch the video.
Yes, I sourced of Tinkernut.com, but I think it follows the sites philosophy of spreading knowledge. He also has other great tutorials I suggest you watch. In this video, he also has other methods of fixing stuck pixels.
Enjoy.

My Programming Languages
07:23:10PM, 29/03/10 AEST-08:11:40PM, 29/03/10 AEST
Well I was bored so I thought I'd post all the languages I know on my blog.
My fist language is C++. It is my favourite and I put the most time into it.
My second language is Java. It is my second favourite and I would put the second amount of time doing.
My third language is JavaScript, as of this time I have not started yet, but will this week (when the holidays start here).
I used Python for a Keylogger only to test how good Python was, I didn't ike it as much as other languages but it was okay. I use MS-DOS at school (because they blocked all good programming languages). Also I use MS-DOS for hacking. I am deeply interestedin Servers and am trying to get a home server.
Maybe, instead of learning JavaScript I should learn MySQL, or PHP or HTML. A poll will be put up.
