I have my first SQL Server project lined up. So I am just interested in hearing some stories from the trenches form people that have been there already. How does PHP and SQL Server 2005 work out together? How do they work out together with *nix or Linux specifically? How do they work together with a Mac (since all the developers on the projects use Macs)? What are the limitations?

I heard some issues with NCHAR's when going through FreeTDS. Since this is a swiss client, we will of course have to make the application localized in German, Italien and French. What extensions are you using? Is PDO_DBLIB worth a look or should one better stick to ext/mssql? I do not envision I am going to do ueberfancy things. Well looking through the requirements we will have to read a PDF from the server. We will also make extensive use of FULLTEXT …

Thanks to Glynn for pointing me to the right thread on opensolaris.org (in a comment on my Good adventures with OpenSolaris post). The package verification thingy (pkg verify -v -f SUNWfirefox) did actually throw an error (indicating some sort of problem). So that’s pretty neat. The fact that it got into trouble in the first place isn’t good, but corruption detection is the next best thing.

I still occationally hit the bug in VirtualBox where if you have 127.0.0.1 in your resolv.conf on your host (e.g. running a local caching nameserver), VirtualBox passes this through to the guest, so the guest tries to use the guest 127.0.0.1 as a nameserver - this usually doesn’t work so well.

The good news is, Firefox now works in my OpenSolaris VM.

The bad news is that even though I’ve gone and …

I came across this error recently when trying to modify the data type of a column.

ERROR 1025 (HY000): Error on rename of './sakila/#sql-1d91_5' to './sakila/inventory' (errno: 150)

Not the first time, and not the last time. A common problem with InnoDB tables, is the lack of information, you need to dig deeper with the following command (and appropriate security a well organized security profile will NOT have).

mysql> SHOW ENGINE INNODB STATUS;

I am very glad to hear that Brian's vision for Drizzle seems to be quite pluggable. This hits home perfectly with my hopes .. well for Drizzle to be pluggable! While I have not had the time to install and play with Drizzle I did stumble over the list of what has been dropped from MySQL so far. I am not sure how complete this list is (for example VIEW's are not listed as having been removed, but it was said that they would be removed), but I assume that nothing on the list is on there falsely. So some brief observations:

1) No windows support, not really surprised about that one. First I assume that none of the developer are interested at this point to worry about Windows, nor do I think that there is much of a Drizzle target audience running Windows servers. That being said, plenty of developer are …

Before I get to post my OSCON reflection I see I didn’t post this (which I reference).

At OSCON opening keynotes Tim O’Reilly Interviews Monty Widenius & Brian Aker. This provided some interesting answers in a Q & A session. Here is some of the discussion.

TO: So 6 months in. How is it with Sun?
BA: Really rewarding environment. My first question was? You are going to send me free H/W. No H/W has been delivered yet, or access to the masses, still hoping. Sun is a very engineering driven company.
MW. Thanks God we didn’t go public. Starting to do closed sourced components, going public this would have continued.

TO: Sun saved MySQL from public market/ insulated from market.
MW: 6 months in, Sun still trying to figure out what they bought. Sun has made a commitment to open source throughout the organization. …

Eric of Proven Scaling commented on a lack of IRC action in the normal mysql channels today when he visited the #drizzle channel on irc.freenode.net.

ebergen: I'm still in #mysql-dev and #planet.mysql but they are hardly active these days [1:51pm]
rbradfor: ebergen: funny, #drizzle is where the action is. [1:51pm]

There is active movement on the Drizzle project. Why is this? Well, I think most importantly is that there is active contribution from the community, at least 5 different companies and more individuals are pushing code to Drizzle, and it’s being accepted and incorporated. Something you can not say about the MySQL Community branch.

As I write this, there are 35 active people on the #drizzle channel now, and 137 members of the …

I was with a customer last week, who leads technology and operations for one of the world's largest companies. We were talking through his priorities for the upcoming year, and on a page filled with various traditional priorities (consolidation, energy management, disaster recovery, regulatory compliance) were two interesting words.

"Open Source."

I asked what that meant, why it was there. He said they'd done an audit of the firm's development activities, and found an overwhelming number ("hundreds") of open source

projects that had been completed behind the scenes, beyond management's oversight. The projects were designed to solve problems deemed too expensive or difficult to solve with proprietary technologies - from meeting a tough budget, to automating a new process. And rather than fight the trend, they figured it was …

The following Lua scripts are the examples are from my MySQL Proxy @ OSCON 08 presentation.

What is released is the Version for MySQL 5.0. A generic version for all MySQL versions is not yet released.

histogram.lua

This script is part of the standard MySQL Proxy examples.

Additional Lua scripts from MySQL forge are available here.

Today I presented with Giuseppe Maxia of Sun Microsystems Inc at OSCON 08 on “MySQL Proxy: From Architecture to Implementation”. I was surprised to find that MySQL has a strong showing with a number of presentations this week.

Our talk covered the basics of MySQL Proxy, what’s coming in future features, and a number of examples of how I have used Proxy in consulting engagements to improve the information retrieval particularly for identifying performance problems.
