I was wondering, since Nokia dropped symbian OS and is going for Windows Phone, what will happen to Qt? Is Nokia planning to continue working on Qt or are they going to drop that too? I heard it's a very good toolkit. Is it still worth learning?

I know there's no such thing as future proof, but I was wondering: how long will my computer last before it becomes too slow to support new software, or general everyday use assuming nothing brakes.

intel i7 3770k

WD caviar black 1TB SATA3

Gigabyte z77

16GB 1600MHz Corsair RAM

Samsung Blu-Ray/DVD drive

SilverStone 750W modular PSU

Cooler Master hyper 612s cpu cooler

no graphics card yet, using integrated one

I don't plan on using it for gaming, just everyday use + some video editing and programming (i'm making small 2D games)

I just built my first computer, and everything works well. But my HDD: Wester Digital Caviar Black 1TB is sort of making a grinding noise when it's working - when the HDD LED is glowing. Now before this I had a laptop and it never made this noise. I just remember my old pentium 2 made the same noise when it's hard drive was spinning. Is there a way to fix this? And also how do I make sure my HDD is using SATA 3. I think I plugged it into the mobo's sata 3 port, but I'm getting speeds of about 50MB/s when transfering files. And one more thing. My PSU has cables that have multiple SATA power ports on them. Is it ok that I am powering my DVD drive and my HDD with the same cable that has 3 SATA power ports.

How do I make an array of objects in C++

With regular variables I would do it like this:

int array_name[5];

array_name[0] = 53;

array_name[1] = 9;

etc.

but what if I have a class called for example Soldier. I can create a regular object called:

Soldier John(var1, var2);

John.attack();

John.defend();

etc.

But what if I want to make an array of objects? How do I do that and pass different variables to the constructor for every object inside that array?

Also is it possible to pass an entire array to a function?

My knowledge of this is very little. I have a couple of questions:

1. To create a windows application in C++ (not console app) do I need to use an external library?

2. Is win32 api an external library?

3. What's the difference between win32 api and .net for C++?

4. Where can I learn to create applications for windows?

5. Would it be best if I used MS Visual C++?

Sorry if some of the questions sound extremely dumb, but I really only know basic C++.

I just upgraded from Vista to 7 and my laptop speakers aren't working. Windows thinks it's outputing sound - it detects the device and everything, but the sound just isn't coming out. I conected headphones via 3.5mm jack and they work. My laptop is HP pavilion dv4 if that's relevant.

There's this program called magic disk and what it does is it simulates a virtual CD/DVD drive so you can mount ISO files on it. I have an ISO of Windows 7. I am currently using Vista. Could I mount the ISO on to the virtual CD/DVD instead of actually burning the image onto a physical DVD, and upgrading Vista to Windows 7?

I'm working on a project with a couple of other people. So basically we need to make a program that uses some other program, without any knowledge of its internal workings. We need to make a file manager that uses the gnome tracker program. How do integrate the tracker with my C++ program.

What if we had two spaceships, travelling in opposite directions, and both of them moving at a speed of 150 000 km/s. So the first spaceship is traveling at the speed of light relative to the second spaceship(if we rounded up the speed of light to 300 000km/s). So how can this be? We know that no mass can travel faster or as fast as light and we know that speed is realative. How can one spaceship move at the speed of light relative to the other spaceship?(and if we imagined that

150 000km/s is a reasonable speed for a spaceship).

I have ubuntu 11.10, I got quite used to unity, I think it's pretty good. I just installed gnome shell, it seems nice but idk. What are the pros and cons of both of these DE. Someone said that unity has design flaws, but I didn't really notice. Gnome shell seems nice, but I can't imagine using it without docky, that just seems impossible! I feel like gnome shell is missing a bottom dock.

What programming languages are used the most in the world of penetration testing?

I mean can I install the OS on the computer. I want to install backtrack 5 from the live ISO file. Can I boot it in the virtualbox and then install it on my hard disk, to dual boot? How can I do this, instead of actually burning the ISO file onto a CD?

What is the programming language Ruby useful for? I have done some programming in C++, Java and Pascal, so Ruby is kinda weird for me since I usually write the code, then compile and run it, and interactive ruby is kinda weird for me now cuz the code executes line by line. What are the advantages to this kind of coding?

I have been learning C++ for a few months now, and every time I used the win32 console application.

Now, can someone write me a win32 app that displays the console and prints out "hello world" or whatever.

I just installed Ubuntu 11.10 on top of Pinguy OS 11.04 which is actually ubuntu 11.04 with a lot of programs installed on it. Anyway I wanted a clean install so I chose to delete Pinguy OS and install Ubuntu. I also have windows 7 installed. And when the installer finished, it needed to restart. When it restarted I didn't get the grub menu, I just got a message that said

grub rescue

grub>

So I didn't know what to do, so I booted my live-CD again. How do I fix this?

I got into C++ about 3 months ago. I learned a lot since then. Before C++ i learned a bit of Java. I never understood java very well. It seamed just sooo, complicated. Anyway I have been using C++ and I never bother making a class. It just seems too much work for my short projects. But everyone just keeps insisting on classes and OOP. I still haven't learned inheritance and polymorphism. It just seems that a simple function can do anything a class, or a method can do. I must say, from what I have learned till now, I don't like OOP very much. And I don't like the rules of OOP very much. I hate the fact that creating global variables is discouraged, even though I follow this rule and all my variables are local. It seems getting around the rules of scope is just a hassle. idk

Do I really need to use classes for tiny programs, or at all?

When I was about 4 I took a pearl and put it in my nose. If I remember correctly got kinda jammed and it never came out. I'm 17 now, and I was just wondering, could it be that it's still there. In the last few months I've been getting nosebleeds kinda randomly. Sometimes I just touch my nose and it starts bleeding usually while sleeping, but once I tried to induce one in class to get out of doing a test lol, it didn't work. Anyway it was a small white pearl, and I never told my parents cause I was too scared.

I need you to recommend me a good C++ book. I'm kinda a newbie. I watched a few online video tutorials in C++ and before that in java. I never learned C so keep that in mind. Watching the online video tutorials I got to pointers and heap memory and the logic of OOP - everything in win32 console application. So now I'm stuck and I need a good book to go further.

Does a 20mW green laser (532 nm wave length) or a 20mW red laser go further?

And what about a blue laser which has the shortest wave length? And also what if we had a infrared laser, or a ultraviolet laser? I know shorter wave length light has more energy. But why does one travel further than the other.

was just wondering :P

So I'm a hardcore Windows user. Had Windows 98 when I was 4. Have been using it ever since. I'm 17 now. Recently I got into programming (C++ mainly), and I'm dying to learn to use the linux terminal. Once my vista broke down, I couldn't boot it, and luckily I had the option to boot Ubuntu. I used it for a couple of months and I loved it. Later I got Windows 7, and seeing what a huge improvement it was compared to Vista, I just kept using it. Then I got ubuntu 11.04, and hated it so much. It just seems that ubuntu 11.04 is the vista of linux. It crashes so much, and I would rather boot Windows 7 any day. So I am looking for a nooby, but stable, linux distro I can use. I'm thinking about Pinguy OS but I'm not sure. My first linux was Fedora 11, it was a few years back, and it seemed sort of complicated at the time, but Fedora has this new weird look.... sooo

______________________________________________

Bottom line: Give me a linux distro that's easy to use/learn and stable.
