The latest from the MySQL community

First of all: Thank you for your positive feedback on the MySQL 5.1 Errata Sheet!

While I never doubted that publishing the 5.1 Errata Sheet was the right thing to do, I had expected a more mixed feedback. It turned out the feedback was very grateful. So thank you for your encouragement

It's been a long time. I suck. One of these days I'll be productive enough to pop out releases.

Unfortunately I've been sitting on this one for a long time. There are significant API updates in this one, but I've cut it just short of being really good. Impatient :)

In Part 1 we have seen how the concept of state management works. Now it's time to apply that concept to a load-balancer. In this Part 2 we will look at a strategy for using Linux Virtual Server with MPP for failover, and also take a closer look at the mechanics of MPP itself.

I've written a few articles on disruption over at my brother's site www.ondisruption.com.  While most people think about disruption only from a technical point of view, you can find disruption across many areas, whether it's the business model, development approach, distribution etc. I've also written a couple of pieces about how disruption can impact your career and what to do about it.

At any rate, here are the links:

It’s been a while since I’ve written about progress on the book. I actually stopped working on it as much at the beginning of the month, because on October 31st I managed to finish a first draft of the last big chapter (Scaling and High Availability)! Now I’m back to full-time work at my employer, and I’m working on the book in the evenings and weekends only. This doesn’t mean the book is close to being done, though.

greg knauss wrote ?wide vs. deep? to explain why he is not happy being management, and what he thinks the difference is between people well-suited to management and those that are not.

i don?t know if i agree with his explanation, but i think it is very important for organizations to realize that there cannot be only one career path that leads up through management. to mysql?s credit, the recent work that was done to standardize our job titles and the path up the ranks acknowledges this, and there is a non-management path for developers. i don?t think we are quite where we need to be in terms of divorcing technical leadership from resource management, but we are getting there.

and mysql is hiring for all sorts of positions.

The MySQL Table Checksum , part of the MySQL Toolkit (having to be renamed soon ) is an invaluable community tool for use with MySQL. Most sites or installations of any volume will use MySQL Replication for one purpose or another, be it for read scalability, backups, testing, upgrading etc.
