Oh yeah I know all about soaking for burns.. partner did the same trick as you, (only his burn was heat, blistered up straight away.. after ice water soaking, no scar) but anyway yeah..

just did up a flight video in fsx... it's terrible

I hate working late shifts, I just end up pinging the **** out when I get home and can't sleep.

It's on Steam, ~1.5GB download. Worth every bit of bandwidth.

Done and dusted last night, had a blast! Will wait and see if my regular cd key site gets them cheaper than they are on Steam after release

I just almost spat coffee all over my keyboard.. read a remark on a website about the protests at Parliment over those idiots in Kings Cross the other night that ran over the lady and were shot at by Police.

"I should have stolen a car, got pissed and rammed the car into their protest, it might give them better perspective"..

[cyclobs]

awesome! got my pingers all coded out.. even though i followed someone else's coding but once it all works i gotta change alot of it anyway to suit my program. i just needed to make sure i can ping stuff!

hopefully this will compile and then i gotta figure out how to.... use it

also i somehow included winspool.h instead of winsock2.h.. i was wondering why my compiler was complaining about printing ****

new hair stuff...always interesting

THIS ONE SMELLS LEIK VANILLA.

Ruby is a ****. I am not enjoying programming.

[revengous]

Ruby is a ****. I am not enjoying programming.

I didnt enjoy ruby all that much, stick with java if you can

[cyclobs]

i don't mind C++. still got tons and tons of stuff to learn, What I'm doing here i only have baseline understanding of it.

[CelticAngel82]

our tafe makes us use ruby.
everyone uses ruby. she's so easy to stick objects into.

[cyclobs]

wee it compiled! .. after needing to do something in MSVS

edit: and my program crashes >.<



later edit: (since people whinge about double posting) Finally got my witcher CD it's awesome, DD's don't compete with an awesome hard cover

[Helelix]

Heh, currently programming an Android app for uni (its in java btw). I gotta say, its easy until you get to an error which doesn't trace back to your code but to a random android library. Hopefully I can finish by 7 and catch the Avengers with everyone tonight....

[cyclobs]

ha! try fixing a problem.. that seems to magically go away when you force it to echo the trouble some variable before being passed into an function

if you don't echo before being passed the program crashes on the first instances of using the variable. but print it on screen before being passed and it works fine..

wtf

[CelticAngel82]

what a great day so far... walked down to pick up my mystery parcel at the post.. found out it's 2 more free books from Penguin (Large parcel yesterday contained 3 free PEnguin books).. dusted off the Wii and played some guitar hero 5 and guitar hero metallica.. some super mario smash bros.. good times, good times...
then for much of the remainder i've been laying here on the couch with a large Toblerone, some Coke and one of my new books Even the cat has been relaxing with me
Headache is still there but it feels great not doing anything.
