The Secret to Raising Smart Kids

Funnel Set
When I was ordering my Arlec safety device Bunnings suggested I might want this Sandleford 4 Piece Funnel Set for $4.49, and how could I say no?
The new funnels have taken their place on the peg board:
Arlec Single Outlet Safety Switch
Thanks to my mate Raz I now have an Arlec Single Outlet Safety Switch from Bunnings. It’s a 30mA residual-current device (RCD), which is a type of earth-leakage circuit breaker (ELCB).

The UPS then has the Arlec device in the back of it, which then powers the rest of my bench (behind the scissors):
You can see I still have my Xbox power cable plugged in. We’re not sure exactly what that does. In addition to an electronic fuse maybe an RCD or maybe an arc-fault circuit interrupter (AFCI) or maybe all of the above.
Two simple ways to version control your MariaDB schema changes
Over on Two simple ways to version control your MariaDB schema changes I learned a neat hack you can use to check for database schema revisions by reporting off the binlog.

$ mysqlbinlog --no-defaults -R -u foo -p -d foodb -h db.home.arpa mysqld-bin.000001 > foodb.txt
Repology, the packaging hub
Today I discovered Repology. It provides info on distribution repositories and their project versions.
Database Workbench from Upscene Productions
My copy of MySQL Workbench doesn’t play 100% nice with my MariaDB install, so I checked out the Database Workbench software recommended by MariaDB and in the end I downloaded a trial version. It runs okay under Wine, so gonna check it out.
