Running software (single instance) in a multi-node cluster might reduce downtimes due to planned maintenance, as the VM can be live-migrated to another node prior to that. This in fact increases the availability of the instance. However this only holds for planned events.
This program solves the 5x5x5 brick-cube-puzzle in less than one second using a sophisticated algorithmic approach. The implementation is both highly efficient as well as easy to understand. The presented techniques are suited for many optimization problems and also can be used for educational purposes.
In the programming language C the programmer is responsible for handling the (heap) memory allocations. This means, whenever memory is allocated on the heap using e.g. `malloc`, the programmer has to ensure that this allocation is released to the OS again. But does this always hold?
Rsync ist ein sehr praktisches Kommandozeilen Werkzeug zum Kopieren von Daten. Leider ist die Performance jedoch nicht immer optimal. Hier zeige ich ein paar Möglichkeiten, die maximale Kopiergeschwindigkeit zu erreichen.
