In May, I presented two talks – one called “Are you getting the best out of your indexes?” and “Optimizing Queries Using EXPLAIN”. I now have slides and video for both of them.

The first talk about indexing should probably be titled “Why is MySQL doing this?!!?!!?” It gives insight into why the MySQL optimizer chooses indexes that you do not expect; especially when it does not use an index you expect it to.

The talk has something for everyone – for beginners it explains B-trees and how they work, and for the more seasoned DBA it explains concepts like average value group size, and how the optimizer uses those concepts applied to metadata to make decisions.

PGConf Silicon Valley was excellent this year: good organization, great speakers, and top-notch vibes in general. We were excited to see everybody visiting (and crowding!) our booth and the overall very positive community presence. Highlights included a presentation about Postgres' use at TripAdvisor, a look at Amazon RDS for Postgres, and consideration of system scalability and the future of relational database management systems.

Baron Schwartz, VividCortex's own founder and CEO, was at the Silicon Valley conference, and he's said that it was the best PGConf he's been to yet. On November 18th, Baron even led a breakout session, titled "Analyzing PostgreSQL Network Traffic with vc-pgsql-sniffer," in which he explained both the principles and practice that come together to result in VividCortex's powerful sniffer tools. Even the questions asked at Baron's talk were fantastic.

I'm very excited to announce that some of my content is featured in the PHP Learning Path from O'Reilly. The Learning Paths are a good way to buy a bundle of content from different people on related topics, and the introductory pricing is always a good deal! Their newest offering is the PHP Learning Path, which has a video course on PHP and MySQL, my intermediate PHP Video course (they wouldn't let me call it "all the things Lorna thinks PHP developers need to know" unfortunately!) and also my video course Git for Web Developers which has a bunch of PHP in it as well as my best git tips and tricks.

I think it's a pretty well-rounded collection and it's only $99 for a couple of weeks, so get the PHP Learning Path here and let me know what you think?
