“Show Slave Status” command has a last column “Seconds_Behind_Master”, which gives us idea about how much time slave is lagging behind master. It is an important to be considered parameter…

So you're a small startup company, ready to go live with your product, which you intend to distribute under an Open Source License. Congratulations, you made a wise decision! Your developers have been hacking away frantically, getting the code in good shape for the initial launch. Now it's time to look into what else needs to be built and setup, so you're ready to welcome the first members of your new community and to ensure they are coming back!

Keep the following saying in mind, which especially holds true in the Open Source world: "You never get a second chance to make a first impression!". While the most important thing is of course to have a compelling and useful product, this blog post is an attempt to highlight some other aspects about community building and providing the adequate infrastructure. This insight is based on my own experiences and my …

For those who wonder why my blogging is so low these days (apart from today) .. I`m actually writing more Lines of Code than Blog Entries the last couple of weeks:)

And when I`m not writing code I`m reading :) Either proofreading an upcoming book on Zabbix or reading some of the other books Packt sent me.

Next to that I`m busy preparing my T-Dose presentation

Oh and did I mention a 40 something questions questionnaire about some merger ?

Following the release of our report, ‘The Myth of Open Source License Proliferation’ and during research for it, we heard and sensed a feeling that open source software licenses had evolved to become a generally well-accepted piece of the the enterprise IT and IP market. However, we also heard from numerous vendors, developers and other individuals that the next battlefront is obviously software patents, which are in need of reform, according to many supporters of free and open source software.

This week, we saw some of the software patent skirmishes that are driving and validating this thinking. There was first news that the Open Invention Network, the consortium dedicated to legal and IP defense of Linux, had bought some software patents that related to …

Some time ago I posted a compilation of applications and programming languages that provide an API to connect to the MySQL Server. As it turned out, I forgot a few that I would like to mention here:

• Apache DBD API: a MySQL driver for mod_apr_dbd is not included in the official distribution, but can be obtained seperately from here. Some distributions (e.g. openSUSE) actually provide installable packages of this driver module.
• GRASS MySQL driver …

1. It’s easy to screw up thread safety.
   If you’re trying to format something for output (e.g. leading zeros, only 1 decimal place or whatever… you know, format specifiers in printf) you are setting a property on the stream, not on what you’re converting. So if you have a thread running that sets a format, adds something to the stream, and then unsets the format, you cannot have another thread able to come in and do something to that stream. Look out for thread unsafe cout code.
2. You cannot use streams for any text that may need to be translated.
   gettext is what everybody uses. You cannot get a page into the manual before it tells you that translators may want to change the order of what you’re printing. This goes directly against stringstream.
3. You need …

This Thursday (June 25th, 13:00 UTC), Lenz Grimmer will explain how to contribute code to MySQL, in a MySQL University session titled MySQL Code Contributions. Lenz is a member of the MySQL Community Team. His session will give an overview about how code contributions to MySQL should be handled and performed. It will cover the ideal workflow, requirements and available infrastructure and toolchain that potential contributors should be aware of.
