I have simple C++ opengl app. It works nice but when texture image is smaller than X*X then program crashes. Any fix for this?
2nd question: How do i make texture repeatitself instead of stretching itself?

There was panic that Dell was going to stop this distribution but it turns out Dell will expand the Linux Ubuntu loaded products. Sounds like a right step to open-source future.

The latest panic in desktop-Linux-land was that Dell would no longer be selling Ubuntu pre-installed on laptops and netbooks. Alas, for those who love drama, it wasn't true. In fact, Dell is expanding its Ubuntu desktop offerings.

Has anyone here used SharePoint much? I know some IT companies seem to like working with it. But when I talk to individual programmers they hate sharepoint stuff.

For those wondering, sharepoint is a microsoft suite of programs that allows you to create dashboards, lists, and website portals and combine them with other databases, but VISUALLY and through wizards. It can be a nightmare to learn how to use.

What do you think of this product? Tell me about your experiences using it.

AT&T has killed its unlimited data plans, and Verizon is rumored to follow suite, read the whole article in the front page:

Great job on the article Vassily, I didn't expect it to become as popular as it was with over 512 diggs!!!!!! Great job... We had over 15,000 unique visitors in a single day, plus 130+ tweets.

So, what did you guys think of these new plans? Will you be switching networks soon? Are you just gonna take it? Do you like the change?

Thanks Digg .

The world's largest technology company has earned another accolade: it was responsible for the largest number of security flaws in the first half of 2010, knocking Oracle off the top spot. Microsoft is in third place.

I'm actually a bit more surprised that Oracle is considered insecure, considering it's regarded as a popular commercial database system. Microsoft is not surprising at all. Apple, not too surprising either.

Your thoughts?

Firefox 4 beta is coming out, and it's completely redesigned. Just take a look here:



It's pretty nice. I guess they sort of tried to use Google's simplicity idea with chrome by gaining back screen space. Getting rid of the bar. Putting tabs up top. Various other little improvements. Although I kind of expected more.

What do you think? You think it's going to be a vast improvement?

Alright, so I have the choice between Cox Cable vs Verizon FiOS.

--- FiOS TV or Cox Cable TV ---
Generally, my requirements have been simple. HD Receiver for TV, Science channel, Military Channel, History, Discovery, Food network, Syfy, TNT, USA, ABC, etc. THat's all I need for TV.

FiOS TV offers 230 channels, including the ones I listed, as Prime HD Tier 1, for $65.00/month (+10$/month for HD receiver) ------------ Cox offers expanded service (does not include science channel), for $53.00/month, and Discovery channels for an extra $2.00/month, and it says science channel is in bonus pack (formerly discovery pack). I picked Cox 'preferred' package, with includes the bonus pak and one premium movie pak I think. Comes out to $62/month (+HD receiver probably 10$/month) in my Washington DC-Virginia area.

Sales trick here: Cox refuses to give you a straight price unless you enter your address.

Looks like Cox is cheaper, but I heard the quality of FiOS Tv is better.

--- FiOS High Speed Internet or Cox Cable Internet w/ PowerBoost ---
FiOS internet offers me $70.00/month for 25 Mbps download (up to). I also bet I'm forced to buy THEIR cable modem.

Sales trick here watch out: FiOS makes it $5 cheaper "with" home phone.

If I bundle and save with FiOS internet+TV...
+ FiOS TV Extreme HD
320+ channels, including 65+ in HD
+ FiOS Internet 25/25 Mbps
Up to 25 Mbps download, 25 Mbps upload
----- comes out to $95.00/month, excluding the promotional period of 85$/month.

Cox, gives me 25 Mbps powerboost internet for $62.99/month, for a combined TV and internet bundle for $121.97/month excluding promotional 95$/month period.

--- Quality / Performance ---
This is what I want to know from you guys---- ANYONE out there HAVE Verizon FiOS or Cox Cable internet or TV?

I need your help, pm me or reply, and we can talk about speeds etc.

Procedural Abstraction and Functions Part 1
1.)Create a program that will ask the user to enter five numbers. Use functions to compute the sum, difference of 1 & 2 entered numbers, product, quotient of 3 & 5 entered numbers.

Sample Output:
Enter number: 1
Enter number: 2
Enter number: 3
Enter number: 4
Enter number: 5


Entered numbers are 1, 2, 3, 4 and 5
The sum of the five numbers is 15
The difference of 1 & 2 entered numbers is -1
The product of the five numbers is 120
The quotient of 3 & 5 entered numbers is 0.6

Another Entry? y for yes, n for no to exit the program

I was reading my gaming magazine today and I found an interesting snippet of the development of oblivian. It is from Game Informer, June '10, page 27.
Gamings strangest glitches by Ben Reeves
Quote:The Elder Srolls IV: Oblivion
"During Oblivion, our new Radiant AI system - which let all the NPCs in the world think and act on their own - led to some of the best bugs. My favorite was a quest where you had to talk to a prisoner in jail. Sometimes, when playtesting, we would find him locked in his cell, dead. It took us forever to figure out why. Turns out, the guards in the jail could run out of food and get hungry. They would then go down and kill the prisoner to take his food. This all happened when the player wasn't there. I still don't remember how we figured it out, but the solution was easy: more guard food."

Hi all,

I am going to start my first online game with UDK. Unity3D was pretty good. I guess, UDK is better than Unity3D. At least, I can make high-quality games with UDK.

Here is my question. How big-online games are working with server. I was using PHP-MySQL to verify user information and login but I can't use it for this game. I need to buy dedicated server or P2P is enough for it?

If P2P is enough, Can I use Php-Mysql to store user point / information?

Max. Player in game: 32
Area: Very big (1000m2)

Any guidelines and ideas are welcome.
Thank you

Okay, I've finally started delving into C++ DLL's (fun fun fun), got a minor annoyance cropping up though. The exported functions on my DLL aren't named the same as in the source. I was wondering if anyone knew anything about this.

e.g.
my DLL exports the function:
AbstractAlgorithm * DLL_EXPORT getAlgorithm()

yet in the exports (and for dynamic loading) the function name is:
_Z12getAlgorithmv

the number appears to relate to the length of the function name, the _Z and the v at the end I have no idea about.

Any ideas?

Many thanks!

I am playing with J2ME but I failed after 2 days with this error. Everything seems good but when I started app. in emulator and click download button, it says     C++ Programming TRACE: <at java.lang.IllegalArgumentException>, Exception caught in Display class java.lang.IllegalArgumentException


My code:
    C++ Programming String string = ""; try { string = getUrl(new String("http://localhost/tvguide/get.php?channel=abc&date=03062010")); } catch (IOException e) { string = "Error"; System.out.println(e); } switchDisplayable(null, getTextBox()); // write post-action user code here textBox.setString(string);


getUrl() is returning String. I guess, I have problem with 'string' variable. When I change it to something like "hello world", it is working but not working with returned 'string' variable.

getUrl()
    C++ Programming private String getUrl(String url) throws IOException { HttpConnection http = null; InputStream iStrm = null; String returnVal = "";   try { // Create the connection http = (HttpConnection) Connector.open(url);   //---------------- // Client Request //---------------- // 1) Send request method http.setRequestMethod(HttpConnection.GET);   // 2) Send header information (this header is optional) http.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Configuration/CLDC-1.0");   // 3) Send body/data - No data for this request   //---------------- // Server Response //---------------- // 1) Get status Line System.out.println("Msg: " + http.getResponseMessage()); System.out.println("Code: " + http.getResponseCode());   // 2) Get header information if (http.getResponseCode() == HttpConnection.HTTP_OK) { // 3) Get data (show the file contents) iStrm = http.openInputStream(); int length = (int) http.getLength(); if (length > 0) { byte serverData[] = new byte[length]; iStrm.read(serverData); returnVal = new String(serverData); } } } finally { // Clean up if (iStrm != null) { iStrm.close(); } if (http != null) { http.close(); } }   return returnVal; }


Thanks
