Hello, I have a very basic ajax slideshow on my website. On every scroll, the new images and response content continually increase the amount of memory used by the browser. I've done my research and tried all suggestions to reset the XHR object on each new request, but this does absolutely nothing to help. The slideshows are basic bu...
I have a java applet that loads up a scroll view that you can add several thousand views to, everything works fine. If I close that browser window and open a new window and view my applet again and start adding views it eventually runs out of memory. It seems like garbage collection didn't occur when I closed the window before: a: why...
I have to work with two C programs that communicate via a file-based interface. That is, each of them has a main loop where it polls three or four files (fopen, fscanf), reacts to what it reads and eventually makes its own changes to the files (fprintf) for the other process to read. Now I have to condense these two programs into a sing...

Hi guys, I need to call properties and functions of an object from a different class. The idea is passing 'this' as a parameter to the other class constructor. E.g.: instance = ClassName(this); And then do: ParentClass parentInstance; ClassName::ClassName(MainApp _instance){ parentInstance = _instance; } However, my compiler ...

I don't know very well about RAM and HDD architecture, or how electronics deals with chunks of memory, but this always triggered my curiosity: Why did we choose to stop at 8 bits for the smallest element in a computer value ? My question may look very dumb, because the answer are obvious, but I'm not very sure... Is it because 2^3 allo...
I'm not sure how to word this exactly but I have a script that downloads an SSL certificate from a web server to check it's expiration date. To do this, I need to download the CA certificates.

In many languages you're allowed to declare a variable and use it before initializing it. For example, in C++, you can write a snippet such as: int x; cout << x; This would of course return unpredictable (well, unless you knew how your program was mapping out memory) results, but my question is, why is this behavior allowed by compil...
