I'm trying to develop some ideas which will wind up in my podcast, so I thought I'd bounce them off the forums here and see what people thought. These ideas are going to be a bit too complex for my podcast's target audience and I'm trying to think of ways to simplify them. I'm sure it's going to take a few successive rewrites in order for that to happen. My apologies to all you blog and Podcast haters out there, but hopefully this explanation will help elucidate you as to why they are important, which is something the mainstream media has horribly failed to describe with any degree of clarity. Anyway, let's begin... The bottom up model describes the process of amateur…

Here's the brief summary of my situation. I'm doing an extra credit project for school and I want to make a game for it. I'm going to create a game using GameMaker on the computer. I'll save the game on a laptop and bring the laptop to school. I'll hook up a projector to the laptop so that everyone can see it. If all of this goes right, I still have a problem. I want four people to play at a time. Any suggestions how I can do this on a cheap budget? I think I have a Dreamcast still around, with four controllers. Is it possible that somehow I can hook up the four controllers to the game and have four people play the game at once? I think GameMaker can do that, but I'm …

I'm sick and tired of the dust. What works the best for you?

Are there any freeware alternatives to Microsoft office that are at least comparable. My copy of Microsoft Office has suddenly decided its an illegal copy after a year of use.

found this website whilst pootling about the web. I think there are a few web desiners that use this forum (in addition to the admins) -- i have absolutely no idea how useful this site will be to you, but it seemed like it might be useful, so there it is: a website that shows you what your color scheme looks like to color-blind people.

I've noticed that data sent across a wireless LAN network can be read very easily if you don't use WEP encryption keys. I was wondering, how far can a signal from a wireless network travel? If I used a wireless network without encryption, could somebody with a very power receiver read my data from miles away?

Im curiouse; what are all of those little slots on my mobo actually for? Does my mobo have some kind of untapped potential? I found a photo of my mobo on the net, and have annotated it to the best of my abilities; if anyone could fill in the gaps, espesially as to the mysteriouse green thing, which has intregued me mightily, that would be appreciated. cheers

my friend set up this domain for me, my brother, him, and another one of our close friends to use as an email address and place to post pictures and the like. im trying to get the email to work through thunderbird and its not working right. i can recieve messages but i cant get outgoing to work. i have tried using the outgoing server provided by the site and their recommended alternative, my ISPs mail server, neither of them work. when i hit send and type in the password the prompt goes away and then comes back blank again. if i just hit enter with no pass it gives me some error about being unable to connect to the server. i know this isnt much info to work with, …

I have had my Hotmail account for about 4 years, and there have been two times where messages that I have deleted appeared in my Inbox. These were messages that I had deleted months ago, and removed from the trash can. However, they just came back into my Inbox. I was sure that Microsoft was secretly keeping deleted messages on their server. I e-mailed Microsoft, and they promised that they did not keep any deleted messages. They claimed that once a message was deleted from the trash can, it was gone forever. I didn't really believe this, and I was still sure that there was a hidden place in my Hotmail account that contained deleted messages. Now, I think I h…

Can someone tell me what prompt is? A person I know told me that it has something to do with saving everything that has been typed in a computer... I don't believe this, as the computer can't possibly hold all this data... So I am curious to know what exactly it is. I know it has something to do with MS-DOS. Also if such a program that saves everything typed does exist or saves all the actions taken, what would it be and how can it be altered ? In case you're wondering, no im not in trouble or anything.. Thnx. Plus, its my birthday today...

I have windows xp home on my laptop. I fi nd myself daily becoming more and more nerdier ( I have 1 gig of ram installed, and a 1.8 gh pentium M with 2mb L2 cache). SO i find myself going nuts and hacking pinball, first the wave sounds witch is cake, then i download resource hacker. So basicaly my pinball is mangled and awesome. I started hacking windows exe's. This is my favorite hack so far. I've changed the text "start" on my start button to DEREK (my name) It even has a little picture of my head in place of the little windows icon, just for laugh's. Now i have a nerd friend, who has a nerd friend that supposedly changed the color of the actual button. I can't …

Hi I have tried to write program to calculate the sum of squares of number from 1 to n without using multiplication and it is supposed to be the efficient. I end up with this function that calculate the square of a number recursively and I made iterative function to calculate the sum of the squares but when it come to write the sum function recursively I could not do it. Take a look. c code for find the square int sqr(int n) { if(n>1) { return sqr(n-1)+n+n-1; } else return 1; } c code for the itritive sum square function int sumSqr(int n) { int i,j,f; for(i=1;i<=n;i++) { if(i==1) { …

Recently, I am told that, application server, like PHP, can handle more simultaneous responds from users to transact with database server, like MySQL...unlike clientside only program, MySQL only allows a few simultaneous connections to it... and more over, it is also more risky since MySQL database URL is exposed..... I am more concentrating on: why can, eg, php, transact with database more efficiently than clientside-only program<--> database server??? any explanation to this?? thanks

Does any one know, or think, of any data recovery software better than GetDataBack? see info: http://www.runtime.org/downloads.htm because my HD has some sort of failure that from now on, every time I start the laptop, it never boot into Windows Xp Home as it usually does... I have managed to install another Xp onto the other partition of the same HD, and I can view the other failure partition, but for some of the folders ,when double-clicked, the computer says something like directory either damaged or corrupted or unreadable or something like that... therefore I try GetDataBack for FAT, but another problem is, it pops up alot of window saying blabla s…

Hi Guys, Lately my broadband internet connection is not working properly. It connects and says 1.5 mb connection but when I load a webpage it loads after like 10 minutes. It is nothing to do with bandwith as this is a new month and I have checked my usage. I have USB EXTERNAL ADSL modem. Help would be appreciated.

Please have a short look on the format below. A:1 B:2 C:3 D:4 This is the Multiple Choice question format in my word. I want to arrange them into A:1aaaaaaaaaaaaaaaaaaaaa B:2 C:3aaaaaaaaaaaaaaaaaaaaa D:4 There are lots of questions which I have to rearrange. Since I always see the required format/arrangement(white words represent space)in my teachers' papers, I wonder if someone here knows this technique and teaches me. Thanks for attention.

Does anybody know how to open the code and edit an .exe file? When I open an .exe file in Notepad, all I can see is the variable declarations and text messages in the program. I also see links to .dll files. The rest of the file is unreadable. Is there any type of software that can read a program and translate it into the original programming language? Since programming language can be compiled into an .exe file, it seems like it would be possible to do the opposite.

A couple of years back I made an attempt at learning C++. I'm now trying to take it back up, here is an attempt: #include <stdio.h> int main() { int xo,xt,yo,yt; float grad; printf("Enter the first co-ordinate:\n"); scanf("%d",&xo); scanf("%d",&yo); printf("And the second one:\n"); scanf("%d",&xt); scanf("%d",&yt); grad = (yo-yt)/(xo-xt); printf("Chord of (%d",xo);printf(",%d",yo);printf(")"); printf(" and (%d",xt);printf(",%d",yt);printf(")\n"); printf("Gradient: %f",grad); scanf("%f",grad); return 0; } The issue I found was that it wouldn't work when I tried printf("string",variable,"string"); so I end…
