Last active August 29, 2015 13:56
Example run arguments line for QtCreator testlib unit test executable for complex project structure. Coverage is collected for "libRowloSqlitePersistence" project's source files and the generated html report is opened with the Opera browser. If a test fails the UnitTestMonitor will be started if found.

rowlo / QListLoopPerformance
Created January 2, 2014 12:11
Performance of creating QList and reverting it.
building list w/o reserve took 1422 ms
building list w/ reserve took 1263 ms
reversing list stack overflow took 185 ms
reversing list stack overflow with max took 159 ms
reversing list stack overflow with max and size took 133 ms

rowlo / buildObjectListWithReserve()
Created January 2, 2014 12:09
Create a list of a million QTimer objects using reserve(int).
QList<QObject*> buildObjectListWithReserve()
{
qint64 size = 10000000;
QList<QObject*> objectList;
objectList.reserve(size);
for (int i = 0; i < size; i++)
{
objectList << new QTimer();
}
return objectList;

Reverse QList one-line with max and size initialization
for(int k=0, s=list.size(), max=(s/2); k<max; k++) list.swap(k,s-(1+k));

Reverse QList as suggested by Marc Jentsch
for(int k = 0; k < (list.size()/2); k++) list.swap(k,list.size()-(1+k));

That shell script starts the leapd service and the LeapControlPanel. When used as autostart script in Kubuntu all you need to do is plug in your Leap Motion controller and enjoy.
