I just had a 30 minutes worth of debugging on a stupid mistake I made. I wanted to check the free space on the target server before I actually start to do the cloning of a database in the python framework we wrote for automating DBA tasks. The check was … Continue reading
I don’t know how many of you are out there but I know at least some who’s lazy enough to rather write scripts than doing the same task over and over again. I’m definitely one of them. I hate repetitive tasks. Just like Abraham Lincoln said: “If I had eight hours … Continue reading

The best pictures will be exhibited in Erkel Ferenc community centre from 16th of October. I’m really hoping at least one of my pictures … Continue reading
