My ongoing dialogue with Matthew Aslett inspired me to read more of his recent writings. An excellent piece Do not sell anything to your community is based on a blog post by Stephen Walli.

Inspired by Stephen, I also looked into a set of slides I recently created and will try that style for this post...

Aslett and Stephen make a great point:

the conversion of community users into paying customers has long been a concern for open source-related vendors. It has also long been a source of friction, with vendors that offer proprietary extensions being accused of “bait and switch” or otherwise undermining the value of the open source software in an attempt compel community …

There’s lots of buzz lately about the so-called “open-core” business model of Marten Mickos’s new employer. But this is nothing new. Depending on how you define it, InnoDB is “open-core,” and has been for a long time. The InnoDB Hot Backup (ibbackup) tool was always closed-source. Did anyone ever cry foul and claim that this made InnoDB itself not open-source, or accuse Innobase / Oracle of masquerading as open-source? I don’t recall that happening, although sometimes people got suspicious about the interplay between the backup tool and the storage engine. Generally, though, the people I know who use InnoDB Hot Backup have no gripes about paying for it.

What is the difference between open-source with closed-source accessories, and …

The Maatkit article on Wikipedia was removed some time ago, after being deemed not notable. I believe this is no longer the case. It’s hard to find a credible book published on MySQL in the last few years that doesn’t mention Maatkit, there’s quite a bit of blogging about it from MySQL experts and prominent community members, and the toolkit is certainly in wide use — it’s important enough that notable companies are supporting its development. It’s available through every major Unix-like operating system’s package repository. On Debian, it’s actually part of the mysql-client package, so if you install MySQL, you automatically get Maatkit too. I believe it’s probably the second most important set of MySQL command-line tools; the most …

Oh my. I was outside painting my house for a few days, and when I return back online I discover that now everyone is having an opinion on the open core business model. Since some participants are still trying to promote it as a valid open source business model, let's see what everyone is saying and highlight any pitfalls being offered...

Last week, Barnes & Noble announced they would cut the price on their wireless Nook eReader, from $259 to $199 ($149 for a new WiFi-only edition.)  Many thought this was a good opportunity for the third place contender to gain market share.  But within a few hours Amazon beat Barnes & Noble's price by $10, marking down the Kindle …

1. Membase -- an open-source (Apache 2.0 license) distributed, key-value database management system optimized for storing data behind interactive web applications. These applications must service many concurrent users; creating, storing, retrieving, aggregating, manipulating and presenting data in real-time. Supporting these requirements, membase processes data operations with quasi-deterministic low latency and high sustained throughput. (via Hacker News)

OpenSQLCamp is less than 4 months away, and I have finally gotten around to updating the site. Special thanks go to Bradley Kuzsmaul and the folks at Tokutek for getting the ball rolling and making the reservation at MIT. Using MIT means that we will have *free* reliable wireless guest access and projects.

OpenSQL Camp is a free unconference for people interested in open source databases (MySQL, SQLite, Postgres, Drizzle), including non-relational databases, database alternatives like NoSQL stores, and database tools such as Gearman. We are not focusing on any one project, and hope to see representatives from a variety of open source database projects attend. As usual I am one of the main organizers of Open SQL Camp (in previous years, Baron Schwartz, Selena Deckelmann and Eric Day have been main organizers too; this year Bradley Kuzsmaul is the other main organizer). The target audience …

Julie Bort of Networkworld.com has an interview with Mårten Mickos of Eucalyptus, formerly of MySQL. In MySQL times it seemed (to me at least) that most users never realized Mårten and his management team were taking MySQL increasingly into a closed source direction. (Maybe I'm just stupid myself, but at least personally I had not noticed this until after I started working for the company.) In this interview Mårten at least comes squarely out of the closet and is defending the model.

Julie makes a good journalistic effort of reporting on the topic from a neutral point of view. Alas, sometimes that approach just makes things fuzzier. So let me try to make one thing clear: Open core may be a good business model, but open core is not open …

What happens when you mention Open Office and Firewall in once sentence, in public ?

People start actually building it (French Article)

Then add to that list that there's also people out there that think that running MySQL over NFS is providing them High Availability, or that using DNS Round Robin will provide them a scalable setup,

So yes .. apparently there is indeed a parallel universe out there.

And no .. I don't want to see Webmin in any Appliance .. that is a joke..., or rather a rant ..

For the last few years I have had an interest in configuration management of IT infrastructure. While by no means an expert I have a considerable amount of experience with the problems associated with mass server configuration and have come to believe it also one of the most under-served disciplines in systems management.

In a previous life I had an operations role maintaining primarily Linux servers and other open source infrastructure. In 2006 I worked on launching the open source NetDirector project, a graphical tool for configuring open source infrastructure like Apache, Samba, LDAP and NFS servers. During that time the challenges of …
