In The Doom of Multiple Storage Engines, Peter talks about how the storage engine concept of MySQL is usually spoken of in positive terms, but there are many negatives.
I have a hard time trying to figure out the deeper meaning behind Peter’s post, given that Percona writes a storage engine for MySQL, XtraDB. Does this mean that Percona will stop developing XtraDB? Does this mean that the Percona Server will diverge farther and farther away from MySQL so that they’re not compatible any more and migrating from MySQL to Percona Server is very difficult?

Liveblog of the Professional IT Community Conference session Mentoring: It’s for everyone
Ways to learn:
Audio
Visual
Kinetic (doing it)
Everyone learns differently, but most people learn with some combination of all these three.

However, you can also learn by training [that's the truth, I learned a LOT by writing the book, even things I knew, I ended up needing to research more].
Ways to train:
Explanation
Observation
Demonstration
Questioning (Socratic Method)

I am moderating and liveblogging the Professional IT Community Conference panel called Tech Women Rule! Creative Solutions for being a (or working with a) female technologist.
One point to keep in mind: The goal is not equality for equality’s sake. The goal is to have a diverse range of experience to make your company/project/whatever the best it could be.
That being said, these issues are not just around women; they are about anyone who is “different”, whether it’s race, ethnicity, gender, sexual orientation, cultural.

Why Python?
- Low WTF per minute factor
- Passes the 6-month test (if you write python code, going back in 6 months, you pretty much know what you were trying to do)
- Small Shift/no-Shift ratio (ie, you use the “Shift” key a lot in Perl because you use $ % ( ) { } etc, so you can tell what something is by context, not by $ or %)
- It’s hard to make a mess
- Objects if you need them, ignore them if you don’t.

Basics
Here’s a sample interpreter session. The >>> is the python prompt, and the … is the second/subsequent line prompt:

[author's note: personally, I use awk a bunch in MySQL DBA work, for tasks like scrubbing data from a production export for use in qa/dev, but usually have to resort to Perl for really complex stuff, but now I know how to do .]
Basics:
By default, fields are separated by any number of spaces. The -F option to awk changes the separator on commandline.
Print the first field, fields are separated by a colon.
awk -F: '{print $1}' /etc/passwd
Print the first and fifth field:
awk -F: '{$print $1,$5}' /etc/passwd
