Whenever I see benchmark results I try to understand if it is technical benchmark - made by people seeking the truth or it is done by Marketing department to wash your brains. Watch out. Whenever you treat marketing benchmarks as technical ones, you make make wrong decision. Take a look at MySQL 5.0 Benchmarks Whitepaper and guess which type is this ?

You can also compare it to my MySQL Performance 5.0 vs 4.1 presentation to have some fun.

What can we see ? Out of all MySQL 4.1 vs 5.0 benchmarks which were done only benchmarks which show MySQL 5.0 is faster were selected and bunch of other benchmarks which show 5.0 is actually slower than 4.1 were hidden under the table.

In general any benchmarks I see which …

I was on the practice webinar for this one yesterday, and it's pretty darn cool. Scott Dietzen, CTO at Zimbra, is giving a webinar on Web 2.0, Zimbra collaboration suite, and MySQL. He even goes into a live demo of the Zimbra Zimlets (AJAX/DHTML components) during the webinar. Pretty killer stuff! It's today at 1pm EDT/10am PDT, so come check it out. Sign up now. There's already over 500 people signed up, so get on the line early to chat with me and the other folks on the line if you want.

In Open source location redux Matt wonders if he should add more sales infrastructure in Europe or less.

(Having said that, Alfresco has realized an immediate gain from adding sales/business development people in Germany and France. Suddenly, many downloads that had been inclined toward a free beer discovered the value of paying for freedom. So maybe the real solution to the "problem" is to invest more sales infrastructure in Europe, rather than less? Not sure....)

I think the obvious answer is to in invest smarter

As an open source company , Alfresco luckily was one of the firsts to realise that the only way to conquer the European market is to be present there locally.

RedHat and MySQL learned this slowly, it took years before customers could match a face to RedHat and even longer to to feel local presence. A …

I seriously hate email.

I know, with email it was once about the love.

The love of the spring, the wine, and the explosion of correspondence. Email that was globally available from and to all my friends. At the time it allowed me to keep contact with people who I would have lost touch with.

I am of course speaking about the early 90's when all of my friends started getting email accounts.

And today?

Today I get thousands of pieces a day.

Today I realized that I should have read all 47 pieces of an email thread on a topic inside of MySQL.

Reply after threaded reply. It would have taken a couple of days to follow it all and piece it together. Replying to each and every comment would have been an issue.

I just hate to believe this is a good use of my time.

There has got to be a better way of handling correspondence, …

It might seem odd, but I've been on the lookout for a decent e-mail system with web access and shared calendaring for quite some time for our family.

I would've found it hard to believe even a few years ago, but now with two adults with full schedules, and a nearly 4-year old in preschool and other events, and an 18-month old with their events and doctors' visits, our family is beginning to have the kind of scheduling problems that only used to happen in large corporations (and thus no cheap solutions were to be had).

We tried Sunbird for awhile last year, but it kept corrupting calendars that we stored on a webdav share out on our family webserver.

We've since switched to Google Calendars, which works great, other than the fact that we don't "own" the data (in fact, I've been backing it up every hour, "just in case").

I'm going to try out Zimbra, since it seems to foot the bill, and it happens to …

I have just gotten an article published on the community section of ez.no entitled Tuning MySQL for eZ publish. The article looks at the different buffers and settings you can tune in MySQL to boost the performance of eZ publish when running on MySQL.

I am interested in getting comments and feedback on your experience on this topic and what can be tuned for futher performance gain.

MySQL issues a cryptic error message, "Error on rename," when you try to alter a table in such a way that it would break a foreign key constraint.
