After a month of intense public review by our community users and contributors, we have made the initial “official” release of the DRBD User’s Guide.

This does not only include helpful information about building, installing, and configuring DRBD, but also on DRBD integration with Xen and LVM, Heartbeat, and many other applications. MySQL users will find the example MySQL HA configurations for both Heartbeat R1 and Heartbeat CRM clusters particularly helpful.

The release announcement is here: http://lists.linbit.com/pipermail/drbd-user/2008-March/009071.html

When we are learning new material we’re going through the next steps.

• Reading manual, books, trying samples from there
• Doing something, basing on the knowledge we already have
• Solving/answering interesting quizes/questions

But there is not much questions/quizes about MySQL, and the recent one is a popular Carsten’s MySQL Pop Quiz serie. We can get a lot off usefull information from such quizes . So, I’ve translated it to russian. I hope it could be usefull for some of us how doesn’t know english well

After the interesting comment storm on Doug’s blog when he posted some of Tim Gorman’s comments on the value of data in his career experiences as compared to the value of the applications manipulating that data, I hesitate a little to post this.

But, I can’t stop myself because it’s such an interesting insight!

Anand Rajaraman, ex-Director of Technology at Amazon.com posted this useful insight that builds on Tim’s. It’s not data vs software as seen by Tim, it’s one step further - more data vs better software.

I like this idea so much I’m hereby dubbing …

You must have heard about Falcon, the new transactional engine being developed in MySQL 6.0. And for all the buzz, you may want to have a look at that.
If you haven’t had time to download and install it, now you can give it a try, thanks to db4free, a free MySQL hosting service, created by Markus Popp.

So, if you want to test Falcon today, get a (free) account on db4free and start hacking!
Be careful:

• MySQL 6.0 is still alpha software!
• The default storage engine in this db4free server is Falcon. When you create a new table, if you don’t specify an engine, you will create a Falcon table.

A sample session:

Nothing to do with MySQL, but I just love observing how technology can make us waste more time. Speech recognition is a wonderful idea, but .... oh just watch this:

Of course, watching this video to the end will cost you about 10 minutes, but it could be worthwhile education. Technology can be very useful. But that doesn't mean that all new stuff is useful, or even suitable for your purpose. I don't think that guy was doing anything particularly complicated or wrong though, and I also commend him for his patience - although you can clearly note his frustration as the experiment progresses ;-)

Prompted by the usual Devshed's post, this time about pgAgent, here I am with a small "tutorial" (or maybe just a small collection of screenshots).PgAgent is a great little tool, much like SQLServer's SQLAgent or the built in scheduling abilities of Oracle and MySQL (which is a much nicer solution IMHO), what's weak is the installation and the docs, I mean, why the pgAdminIII installer does ask
