Some of you might have noticed that I`m cochairing the devops track for DrupalCon Munich,
The CFP is open till the 11th of this month and we are still actively looking for speakers.

We're trying to bridge the gap between drupal developers and the people that put their code to production, at scale.
But also enhancing the knowledge of infrastructure components Drupal developers depend on.

We're looking for talks both on culture (both success stories and failure) , automation,
specifically looking for people talking about drupal deployments , eg using tools like Capistrano, Chef, Puppet,
We want to hear where Continuous Integration fits in your deployment , do you do Continuous Delivery of a drupal environment.
And how do you …

• OTN MySQL Developer Day in May 2012 – New York.
• Effective MySQL Meetup York and …

I was checking out my schedule as I prepared to submit some talks to Percona Live: NYC, when I noticed that it conflicts with Oracle OpenWorld, and starts the day after MySQL Connect finishes. The dates for Oracle OpenWorld were announced at the end of last year’s OpenWorld, so Percona has made a bold statement by choosing to conflict with Oracle OpenWorld. I do not believe Percona knew about MySQL Connect, but it’s happening all the same.

This is all mostly to say that I cannot attend Percona Live: NYC – I have obligations as an Oracle ACE Director to attend some meetings before and during Oracle OpenWorld, but even if I did not, I just submitted presentations to MySQL Connect and it’s not feasible for me to do that …

Security-Enhanced Linux or SELinux is a Linux kernel feature that provides a mechanism for supporting access control security policies. It enables a system administrator to create an extra set of rules that define allowed operations for programs even after the standard controls are checked. In other words, SELinux can help improving system security by restricting access of an application to only a few resources it actually needs, which makes it more difficult for an attacker to gain access to the entire system through exploiting any possible vulnerabilities in the application.

However as rarely anything in life is free, is there any price we have to pay to use SELinux on a MySQL server?

I ran a simple MySQL benchmark first with database working in a system with SELinux enabled (SELINUX=enforcing), and then also with the extra security layer entirely disabled (SELINUX=disabled).

I have previously posted about the SQL MERGE statement, and how powerful it is here: https://blog.jooq.org/arcane-magic-with-the-sql2003-merge-statement/ Unfortunately, not all databases support this statement. Also, very often it is quite a bit of overkill, when what you want to do is to simply INSERT or UPDATE a single record, depending on whether it already exists. MySQL's … Continue reading How to simulate MySQL’s INSERT statement extensions →

In case you missed the MySQL Utilities webcast, a replay is available:  http://t.co/7bFAV083

This webcast is a nice overview of all the MySQL utilities including examples. Check it out and see how the MySQL community is going to get automatic failover backup from Oracle.

Please join me tomorrow (Wednesday) for a webinar about the new version of pt-online-schema-change, Percona Toolkit’s tool for performing nonblocking ALTER TABLE operations. Registration is free. I will explain how the tool works and cover some typical use scenarios. This might be helpful if you’re trying to decide whether the tool is right for you. I am also planning to leave plenty of time for questions!

If you have not signed up yet for the OTN Developer Day: MySQL in NYC, hurry time is running out! This is shaping up to be one of the largest developer days yet. We have a great line up of speakers. I look forward to seeing them and a great community turn out Wednesday.

I wanted to take this time to talk about one more under-the-hood goody we’ve added to v6.0. In particular, we’ve been working on our locking schemes and have made …
