I was contemplating switching to Linux for C++ development, coming from a Windows environment. Is this a bad idea? My workplace uses Windows and Visual Studio for our projects (some C# and java too, but right now I'm only developing in C++). If they decide to put me on a C# project, would development still possible (mono?)? What are the...
Is there a way to force SVN to be case insensitive? We have an issue where a user commits from a linux environment with files say "file.ext" and "File.ext". Works just fine. The problem, however, is when a user on a MAC OSX or Windows attempts an update/checkout. The two files are considered the same and the action fails in error. ...
Is it possible to make an executable look like a read-only file on Linux, such that opening the "file" for reading actually executes the file and makes its stdout available for reading as if it were data in the "file"? It should be openable by any program that knows how to open a file for reading, for example 'cat'. ...

When you perform ls in a bash shell, sometimes there are colours to indicate different resource types, and you can enable/control this with the --color argument. But neither the man page nor Google is providing an answer to the question: What do these colours indicate by default, and how do I display what the current system uses? UP...

I'm trying to calculate the total size in bytes of all files (in a directory tree) matching a filename pattern just using the shell. This is what I have so far: find -name *.undo -exec stat -c%s {} \; | awk '{total += $1} END {print total}' Is there an easier way to do this? I feel like there should be a simple du or find switch th...
I want to force the Linux kernel to allocate more memory to applications after the cache starts taking up too much memory (as can be seen by the output of 'free'). I've run sudo sync; sudo sysctrl -w vm.drop_caches=3; free (to free both disc dentry/inode cache and page cache) and I see that only about half of the used cache was freed...
I need to sniff TCP traffic into my application. Can libpcap reassemble TCP segments or I have to do it manually? The home page says "Full documentation is provided with the source packages in man page format". After I sudo apt-get install libpcap-dev I only find one man pcap. Is it all the documentation available or I simply missed so...
I'm currently trying to get an inode for a given pathname in a kernel function. All I have available is the full pathname. I've tried attempts like: user_path_at(AT_FDCWD, buffer, LOOKUP_FOLLOW, &path); But the dentry in that given path isn't valid, it seems to turn out. Then I thought perhaps trying stat() and getting the inode numbe...

I have created a program that creates a window using XCreateWindow. This works perfectly on my system and many others but on many, it is causing a few weird problems. e.g. the ID that I got from it clashes with the id of the terminal from which the program is launched. In one such case, gnome-terminal also has the window ID of 0x2400001 ...
Does anyone know if it's possible to force terminal to append a \n to every line it prints (or something similar)? I'm trying to debug some insane code which gives me errors the full width of my (24") screen and three lines long, so I'd appreciate not having to copy things into gedit and manually spacing them out every time I press make...
