YAPCEU 2010 – Day Two…
+1 Vote Up -0Vote Down

After enjoying the excellent hospitality of our host here in Pisa (6 courses) we were ready for our second day at YAPCEU 2010 here in sunny Pisa.

Larry’s new catch phrase “My Language is a four letter word” was the ‘Buzz word’ for today. We settled down to some very interesting talks, the highlight for me being Tim Bunce’s talk on using Devel::NYTProf to Optimize your code. Tim first gave us a quick and dirty overview of optimization which covered the basics of where to start and what to look for he followed up with real examples of Optimizer output and than wrapped up with a few before and after results on an optimization effort.

The rest of the day was dedicated in my opinion, to the future of DBs in with Nelson Ferraz giving an excellent presentation of his concepts for using Perl as to glue for a Data Warehouse application. Next on my agenda,

A Pythian Fork
+4 Vote Up -2Vote Down

Today marks my last day at Pythian. I have been at Pythian for almost three years. In those three years, Pythian’s already thriving MySQL practice has grown even more. I have worked with big and small clients alike, across many industries, managed a team of up to 4 DBAs, and learned a lot not just about MySQL, but what my goals are in general.

Though I am leaving, everything I said in the blog post I made when I announced I was coming to Pythian still holds true. Pythian is a challenging environment and one I would recommend to anyone who finds their current DBA environment boring that they should come to Pythian and experience what it is like to work here. I had lunch with Paul Vallee yesterday and we even discussed possible future collaborations (hence the title, a joke that I am

The Doom of XtraDB and Percona Server?
+7 Vote Up -5Vote Down

In The Doom of Multiple Storage Engines, Peter talks about how the storage engine concept of MySQL is usually spoken of in positive terms, but there are many negatives.

I have a hard time trying to figure out the deeper meaning behind Peter’s post, given that Percona writes a storage engine for MySQL, XtraDB. Does this mean that Percona will stop developing XtraDB? Does this mean that the Percona Server will diverge farther and farther away from MySQL so that they’re not compatible any more and migrating from MySQL to Percona Server is very difficult?

Or maybe it’s just that Peter is saying one thing and doing the opposite; which just seems wrong because that would be blatant hypocrisy on Percona’s part.

(This idea was a comment on

My thoughts on Ada Lovelace Day, A candid conversation with Sheeri Cabral
+3 Vote Up -2Vote Down

I had an interesting conversation with Sheeri yesterday. She had pointed out that today was Ada Lovelace Day, a day devoted to highlight and thank the many women in the Information Technology industry for their contributions. She suggested that if I wanted to blog about it she would find that appropriate, given what we’ve achieved here at Pythian.

First, I consider that a huge compliment. And then, a distant second, I told Sheeri – no I don’t think I’ll blog about it, that’s not my thing.

This is the IM conversation that came out of that email exchange when Sheeri and I connected about an hour later. You may or may not find it interesting, but ultimately I thought it was interesting enough to share.

tl;dr: Happy Ada Lovelace Day.

Logs Go Un-Buffered Worldwide
+0 Vote Up -0Vote Down

I regret to say, there is no Log Buffer this week, as we’ve all been busy preparing for the Big New Thing coming in a few days. The good news is, we have a Big New Thing coming in a few days. Stay tuned for that, you won’t want to miss it.

LB will be back in a week, with Gerry Narvaja at the helm. In the meantime, I invite you to leave a comment with your favourite DB blogs from this week — MySQL, Oracle, Microsoft SQL Server, DB2, Postgres, Ingres, or other relational/NoSQL databases.

Log Buffer #160: a Carnival of the Vanities for DBAs
+4 Vote Up -0Vote Down

Welcome to the 160th edition of Log Buffer, the weekly review of database blogs.

MySQL

Blame it on MyISAM, says Mark Callaghan of High Availability MySQL, on considering sql_mode and type coercion. “I think that MyISAM has its place,” writes Mark. “It does fast table scans, but InnoDB is much faster on just about everything else. I am just not thrilled with the impact it has had on MySQL.”

Not that those other engines are without flaw. Peter Zaitsev reports on an InnoDB performance gotcha with larger

Log Buffer #149: a Carnival of the Vanities for DBAs
+0 Vote Up -0Vote Down

This is the 149th edition of Log Buffer, the weekly review of database blogs.

MySQL

Let’s begin with the big-picture stuff. Jeremy Zawodny laid out his view of the state of MySQL in Linux Magazine’s blog, noting the rough transition between versions 5.0 and 5.1, the status of storage engines, and outside contributions.

Like Baron Schwartz’s Maatkit, for example. Baron announced this week that he is writing a book about Maatkit, and also

Steal This Blog Post
+0 Vote Up -0Vote Down

I have been talking more and more with colleagues about the Open Source community and licenses. Zak Greant recently wrote in Free Culture vs. Fear Culture vs. Fee Culture that, “People with bad intentions will do bad things . . . often regardless of the license on the work.”

And, unfortunately, he is right. If I release an article or presentation video with a Creative Commons license, it is still possible for my work to be plagiarized, and if it is, I will still feel violated.

Many of us who use Creative Commons or MySQL have an Open Source mentality. We often do not see value in pirating software—why would we use Microsoft Word (a legally licensed copy, or pirated) if we can

Issues Booking the MySQL 2009 Conference Hotel
+0 Vote Up -0Vote Down

So, a colleague ran into issues booking the Santa Clara Hyatt Regency Hotel—apparently there were no rooms with 2 double beds left for the MySQL 2009 Conference and Expo.

I could not imagine that the conference hotel would sell out so quickly!

The conference’s travel/hotel web page links directly to the online reservations page at http://santaclara.hyatt.com/groupbooking/clara2009orea.

I went there and did a little detective work. What I found was:

  • When I chose Mon Apr 20 - Thu Apr 23, there were rooms with 2 double beds available.
  • When I chose Sun Apr 19 - Thu Apr 23, there were rooms with 2 double beds available.
  • When I chose Sat Apr 18 - Thu Apr
