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 :)

Notable API changes:

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.

Why is it needed?
There are two primary compelling reasons. First, MySQL replication is an asynchronous process and there is no absolute guarantee that the Master Database and the Slave Database are the same (By definition that can be different). Second, MySQL does not provide any tools relating to checking, managing, reporting differences. Luckily the community has addressed this present lack of product feature in current …

Welcome to the 70th edition of Log Buffer, the weekly review of database blogs. In honour of the start of cold-and-flu season, we start with an item on blob streaming. Paul McCullagh, the developer of the PBXT storage engine for MySQL, has made available his presentation on the BLOB streaming project, on his PrimeBase XT blog. [...]

Last week, Hyperic hosted a gaming party at their offices, with plenty of open source people there from MySQL, MuleSource, JasperSoft and others. Ross Mason, co-founder of MuleSource, flew in all the way from Malta, just to play some Wii Tennis. (Ok, maybe he did have some other meetings in town, but I'm sure this was the highlight.) While I was quickly eliminated in the Wii Tennis matches, I had a good time playing the latest version of Guitar Hero III. Not as good as Javier, who obviously is not busy enough given his 200 note streaks, but still respectable... READ MORE
