MySQL admin with Ian Gilfillan

I was doing some reading today and I came upon an old series of articles over on www.databasejournal.com by a dude called Ian Gilfillan:

For the ‘type’ in SQL ‘EXPLAIN’ Ian says: from best to worst the types are: system, const, eq_ref, ref, range, index, all.
It seems this Ian Gilfillan fellow has been rather prolific.

KDEInit could not launch ‘/usr/bin/kcachegrind’

When I open *.xt files from Dolphin on my KDE Plasma desktop Dolphin would lock up while kcachegrind ran and then when I exited kcachegrind Dolphin would complain:

KDEInit could not launch '/usr/bin/kcachegrind'

So what I’ve done is to create a custom kcachegrind.sh script to run xcachegrind properly and then re-associated *.xt files (application/x-kcachegrind) with the new script in Dolphin.

Bug fixed!
