"Bernhard said you might not seem very good at something when you start out, but if you’re persistent, tenacious even, you can get amazingly good."


"Bernhard told a story of a friend who did a drawing every day, for more than 3 years, and became amazingly good by the end of that stint."

MongoDB and MacPorts (and v8)

In order to upgrade MongoDB to the latest version (using MacPorts), I had to deactivate v8, upgrade MongoDB and activate v8 again:


--->  Configuring mongodb
Error: mongodb cannot be built while v8 is active.
Error: Please deactivate v8 and try again.
Error: You can reactivate v8 again later.

Starting MySQL on Mac OS X 10.8.4

I used to start MySQL 5.5 (MacPorts) on my Mac using the following command:
$ sudo /opt/local/share/mysql55/support-files/mysql.server start

Yesterday, I found out that this was not working anymore. The error message I was getting was the following:

$ /opt/local/share/mysql55/support-files/mysql.server start
Starting MySQL
. ERROR! The server quit without updating PID file (/opt/local/var/db/mysql55/monastery.local.pid).

It turns out that the new way of starting MySQL is the following:
$ sudo port load mysql56-server

PS. During the process, I have also updated MySQL to version 5.6.
