When installing Eclipse on Kubuntu, install on /usr/local, otherwise you may have issues with the plugins install

CDT
- tab spaces not taken into account (Helios, Ubuntu 64 bits)
- Needed to do a "apt-get update" after installing CDT otherwise, gave me funky compile error messages on printf and stuff
- To access the gdb CLI, select the gdb process node in the Debug view. The gdb command line will then be available in the Console view. Though no prompt is visible, you can enter commands at the bottom line of the Console view. Doing so may desynchronize the IDE and gdb, so be careful when driving the debugger using this interface.
- automatic save: Windows > Preferences > General > Workspace

cmake

create  a sibbling directory of the sources root:     search-l-2S-build 

cd search-l-2S-build 

cmake -G "Eclipse CDT4 - Unix Makefiles" -D CMAKE_BUILD_TYPE=Debug ../search-l-2S 

In eclipse CDT:

File > Import Existing Projects into Workspace > Next

Select root directory => Répertoire "cmakebuild" créé plus haut

Source accessible in "Subprojects".

./eclipse_cdt -vmargs -XX:PermSize=512m -XX:MaxPermSize=512m -Xms1024m -Xmx1024m

J2EE
You just get "Dynamic Web Project" creation menu only when you install J2EE Eclipse version

Useful files
    - eclipse.ini

if you get black zones within the Eclipse editor, you will have to switch from GTK3 to GTK2. To do this, add the following two lines to eclipse.ini  

--launcher.GTK_version

Problems

when using the maven plugin, the "Java build path" in the Eclipse will take the default JRE Eclipse config unless you specify "maven-compiler-plugin" as artifact in the pom.xml with version 1.8 for example

C# survival kit

* C# is the first “component oriented” language in the C/C++ family

* csharp string <--> C++ wchar_t
* to display a string from multiline (somewhat equivalent to the C++ backslash ):
string toto = @"toto
toto";
* One must specify “override” to the method in the subclass if one want to override a virtual method from the superclass (as opposed to C++ where override is automatic)
* Mutexes are of two types: local mutexes and named system mutexes. If you create a Mutex object using a constructor that accepts a name, it is associated with an operating-system object of that name. Named system mutexes are visible throughout the operating system, and can be used to synchronize the activities of processes.
