I am running the Eclipse-C/C++...
Hello, I have been trying to use fflush to make a progress bar. To test fflush, I wrote the small code below. It works as it supposed to when I uncomment "sleep(1);" but it works in an unexpected way if it remains commented out. It prints the first dash, waits than prints all remaining 9 of them and quits. I don't understand why it...
Hi, I wanted to know how to do this. I realize this is kind of esoteric knowledge, since it's not really necessary. However, it is a topic of interest to me, and I would like to know about it. What I don't understand is how compiz works as a whole. If gtk-window-decorator is just a program by itself (which I believe it is), then how do...

I tried to use the read/write file descriptor in bash so that I could delete the file that the file descriptor referred to afterward, as such: F=$(mktemp) exec 3<> "$F" rm -f "$F" echo "Hello world" >&3 cat <&3 but the cat command gives no output. I can achieve what I want if I use separate file descriptors for reading and writing: ...
Another dev checked his .rvmrc into the git repo. I've since removed it and added it to gitignore, but every time in need to go back in time it overwrites my .rvmrc. I'm on OSX, so I've discovered I can use the OSX file locking mechanism ("Locked" checkbox in Get Info) to stop this happening on my dev machine, but how would this be don...

I'm a noob to how shared libraries work on linux. I am trying to understand how do applications resolve different revisions of the same shared library at run-time on linux. As far as I understand, a shared library has three "names", for example, libmy.so.1.2 (real-name i.e. the actual obj file) libmy.so.1 (SONAME, which is embedded ...
What this is meant to do is, collects the arguments which are the names of the image files and checks them if they exist and are readable, then it converts the image to the preview file in the layout (imagename)_preview.jpg and underneath it it would have the size of the orignal file in 'bytes'. Here is my script. #!/bin/sh clear for i ...

I've developed a site that requires high quality resizing of uploaded photos. The site works perfectly under ASP.NET on Windows. This afternoon I tried running it under Mono/Apache/Ubuntu 10.10. To my surprise, it worked - except for the image resampling. It seems the libraries underlying Mono's Graphics/GDI+ implementation don't imple...

Can you limit the Depends: field in your control files to specific versions, lists of versions, or ranges of version as you can in dpkg? It also seems to me that ipkg out of the box only supports the architectures "arm" and "all", and not x86, which is what I would like to use. Is this a simple modification to the source or a config fi...
