F> Loan to study in UK

slimyboy — Wed, 29 Sep 2010 13:10:53 +0800

Hello there, I have finished my 1st year here in UCTI.
I have applied to transfer to a uni in UK to continue studying in Computer Gameplay Design & Production for my Level 2.

I have been Googling for the past week or so and I can't seem to find any sort of pinjaman/loans for me. I doubt I can get any scholarships as my 1st year results has a CGPA of 2.75.

Help please?

CS1.6 + Win 7 Pro 32-bit

slimyboy — Fri, 13 Nov 2009 19:09:45 +0800

Okay so I just got my copy of Win 7 downloaded from MSDN.

I have:

1. Downloaded Steam & Installed CS
2. Downloaded new Nvidia drivers
3. Installed drivers for my headset, keyboard, mouse etc.

When I create a "New game" on to test with myself, the game seems to run faster than usual (footsteps, shooting etc)

When I join a server online, everything seems to be okay.

1. My fps is constant 100
2. My ping is 15-20 on Msia servers and 25-35 on SG servers

BUT;
I seem to walk/shoot faster there as well, and I seem to get stuck after every 3-5 seconds for 1 second. Then I'll be able to move again, in that "faster" speed.

I dunno what's wrong.
CS worked fine with my Vista ulti.
I had a friend look at me play and it seemed like I was using a speedhack from his point of view.

I have no idea what's wrong, I've been Googling around as well and it doesn't seem anyone else is facing this...

Edit: I played Assassin's Creed and FIFA just to see if it's my GPU's fault, doesn't seem like it.

PC specs :

C2D E6400 @ 2.13Ghz
3GB Kingston Valuram
XFX 9600GT XXX
Steelseries Siberia USB

Edit #2: I turned vsync on and it's okay now, but I'm stuck with 75fps.
Any help with that? I tried refreshlock and everything

Need help with OOP.

slimyboy — Sun, 06 Sep 2009 22:35:14 +0800

is it possible to split my main code to objects? My friend and I have this assignment due on Tuesday and we'd like to apply OOP for extra points but have no idea how. Help/feedback is greatly appreciated!

If OOP is not possible. May I get some suggestions about anything that can be incorporated in this program using OOP? We're completely drained =/

Hey, my girlfriend and I have been going out steadily for quite a while now.
We're kinda looking into the future and trying to see ourselves together. Although we would really want to, there is a BIG problem lying ahead for us. She's kinda strong on her Buddhist believes and well, I'm a Muslim.
I need your opinion on this. What should I do? I really love her, but I think when the time comes, we would have to separate.

Just imagining it feels really hard .
One more thing, we have been discussing it together but always end up being inconclusive. She's about to go abroad to study soon, and she said it'd be easier for us if we'd end things there.

I don't want this

USB ports suddenly not working.

slimyboy — Sun, 05 Apr 2009 13:28:22 +0800

Hey guys, I turned on my PC yesterday and my rear ports just suddenly stopped working.
My front ports are fine, but I only have 2 in front.
I need the extra ports to plug in my thumbdrive, iPhone charger etc.
Need help

P/S: If I plug in my Diamondback 3G at any of the rear USB ports, it lights up even when the power is off. Weird ass shit.

Update : Now I'm reduced to only ONE usb port. I don't know what's going on. And when I plug in my iPhone, it just charges it but isn't detected by iTunes

Solved : Managed to fix it by uninstalling all the USB root drivers and restarting pc
