IO may be blocking/non-blocking and synchronous/asynchronous. POSIX API provides synchronous blocking API (e.g. classic read, write, send, recv calls), synchronous non-blocking API (same functions, file descriptors opened with O_NONBLOCK flag and IO-multiplexing calls) and asynchonous API (functions...

WITH CTE_name (column_name[,...]) AS ( SELECT column_name[,...] FROM base_table UNION ALL SELECT column_name[,...] FROM CTE_name WHERE <recursion limiting condition> ) SELECT column_name[,...] FROM CTE_name

STL style iterators on Qt Container can have some negative side effect due to the implicit-sharing. It is advised to avoid copying a Qt container while you have iterators active on them. QVector<int> a,b; //2 vectors a.resize(1000); b = a; // b and a now point to the same memory internal...

There are a variety of technologies for "packaging" Java applications, webapps and so forth, for deployment to the platform on which they will run. They range from simple library or executable JAR files, WAR and EAR files, through to installers and self-contained executables. At the...
