Why is searching the manual so hard

As a consultant I often use the MySQL Reference Manual to provide additional information for clients. I am very happy to recognize the quality of the content in the MySQL documentation, but why is the searching of the manual so, so bad?

Presentation: OpenStack QA – Walkthrough of Processes, Tools and Code

Last night I gave a short webinar to some folks about the basics of contributing to the Tempest project, which is the OpenStack integration test suite.

LevelDB is here. It might make an interesting storage engine for MySQL as it has many performance benefits at the cost of a few limitations: no multi-statement transactions and MyISAM-like concurrency.

In this post I want to show new possibilities which open with Percona XtraDB Cluster.
We will create 3 nodes Cluster with nodes on different continents (Europe, USA, Japan) and each node will accept write queries.
Well, you theoretically could create 3 node traditional MySQL ring replication, but this is not what you want to use day-to-day.

Documentation in SQL: CALL for help()

Documentation is an important part of any project. On the projects I maintain I put a lot of effort on documentation, and, frankly, the majority of time spent on my projects is on documentation.

The matter of keeping the documentation faithful is a topic of interest. I'd like to outline a few documentation bundling possibilities, and the present the coming new documentation method for common_schema. I'll talk about any bundling that is NOT man pages.
