I've got a file and a patch for it. I'd like to visually apply the patch, t.i. see how the changes proposed by the patch look in context, make some corrections, and save the resulting file. What tool can do that? Neither of the visual diff tools (i.e. meld, diffuse, diffmerge) do what I want: they don't work with patches, they merely m...

I am looking for a hardware, which must run about 256 computationally intensive real-time concurrent tasks in 24 hour mode (one multi-threaded C application). Each task takes about 40-50 MFLOPs, so all tasks require about 10 GFLOPs. CPU-RAM speed is insignificant. All tasks must be managed by a Linux Kernel (32 bit, with SMP). I am look...
I have a specific problem. I am starting learning OpenGL and I am not sure, how to set it up on (Ubuntu) Linux. I think that this could be a way: ======================================================================== OpenGL is only a graphics language "specification" (or "interface") and to properly use it I have to download some lib...
I have a multithreaded application written in C++. And I'm using mutex for file writes. I have a suspicion that somewhere during the execution of the program, the mutex isn't being released. So I was wondering if there was a way to check for mutex locks and releases on a file, programmatically or otherwise. I'm running the code on SuseLi...

I'm experimenting with Xlib to gain a deeper understanding of how Linux GUI programs work. I've written a simple program that display "Hello, world" in a window, but it looks rather anachronistic since the text is not anti-aliased. What is the best way to display anti-aliased text in X11? How is anti-aliasing implemented in GTK, Qt, and...
These are some of the things that every web developer should know when building a web app. This tools will save everyone lots of time. Tools like "memcached" and "beanstalkd" are super dead simple and provides lots of value. If someone could list their simple yet effective tools in this list, it would be good. I'll make this community...
Where can I find the infamous list.h from the linux kernel? I remember seeing it at once point and I can't for the life of me find it again. I'm running a Windows box so it would be great if you can point me out to a nice HTTP site where it's hosted :) Thanks. ...
Hi, I'm tackling a trivial buffer overflow (yes, exploitation; but unrelated to the problem) I'm trying to figure out the fields in the memory map, when GCC's stack protector is enabled. As an illustration: $ ./overflow *** stack smashing detected ***: ./overflow terminated ======= Backtrace: ========= /lib/tls/i686/cmov/libc.so.6(__for...

Hi, I'm using Debian x64 2.6.26 to host a server application we've written in C++. Sometimes GDB gets activated on its own and it uses 100% CPU time giving no room for other processes to run. The GDB version is 6.8-debian. I don't know why this happens and how may i prevent this. It seems that it only happens when out server application...

What is the most reliable and fast method for copying virtual machines files from one server to the other, assuming that I always use sparse file for my vmware virtual machines? The vm's files are a pain to copy since they are very large (50 GB) but since they ...
