I continue to work on figuring out why some feed entries aren't making it into the PlanetMySQL aggregated feed database. Even with all the logging printouts I've added, some feeds continue to get left out; I'm not sure if it is a Magpie caching issue or not, but that's the first place I'm going to examine. In the meantime, if you know your feed entries are not making it into the planet feed, please shoot the community team an email at community at mysql dot com and let us know the details of the feed so that we can diagnose the issues.

While working on the planet code, I started thinking about ways that we can improve the PlanetMySQL website and functionality. One of the most frequent issues that I hear come up is the sheer volume of items that get aggregated by PlanetMySQL (when it's working correctly of course... ) and the fact that some folks just don't care about certain blog entries …

Now since I reinstalled Vista 32bit version and its up and running, lets go through what works what don’t.

1. Daemon Tools (check)
2. Microsoft Office (check)
3. Trillian (check)
4. VMWare Server (CHECK!)
5. Diskeeper 10 (Nope, apparently I have to go download an update for Vista, postponed)

Ok now the fun part starts. How to get everything working the way I want to.

I need to start my Fedora virtual machine so I can get some development/testing done. And a wall I hit. It says that I don’t have permissions to open the file. I am logged in as a user which belongs to Administrators group. So why do I not have permission? Well let me copy it to desktop and see if that works. Voila! it does! Ok.. I will let this one go since I have already wasted my whole weekend getting Vista going.

OK.. so lets change my hosts file so I can point some domain names to …

In the last month we've had two updates of new transactional storage engines for MySQL.  Falcon, the new storage engine developed by DBMS guru Jim Starkey is now in Alpha.  And PBXT, from Paul McCullugh at PrimeBase has a new Beta available with referential integrity.  Both use the new storage engine facilities of MySQL 5.1 and are important developments giving more choice to developers building transactional applications.  I'm sure there will be more information on these and other storage engines at the …

OK, I am in Stockholm, at a development meeting. Stockholm is a nice city. It has soul, and it is smart. Probably the best European capital I've been to.

This is my first impression - so far I've seen only a few quarters and the road from the airport. But something tells me it'll stay that way. Maybe I need not see the city and an image is ready made. I like the roads, the houses with walls that are 4-5 bricks thick. And it's the first airport with oaken parquetry floors I've been to.

Tomorrow is a day to revisit some prehistoric server problems, such as Bug#989. Need to get back to preparing my lot.

PS I can't make my P990 work with Linux. So no photographs until I get back home.

I already wrote kind of about same topic a while ago and now interesting real life case makes me to write again

Most Web applications we're working with have single tier web architecture, meaning there is just single set of apache servers server requests and nothing else - no dedicated server for static content, no squid in front nothing else. This architecture is frequently used even for medium size web sites which have millions of page views per day.

Typically single Apache server in this configuration will have rather high MaxClients settings (in hundreds) and would argue web site performance suffers if the value is decreased, only few however understand why they need MaxClients to be set to some high number. …

Q: Will future versions of mysqlnd support PHP 5?
A: Yes, future versions of mysqlnd will support PHP 5.

However, currently we focus all our development efforts on implementing core functionality like Unicode support and support for Prepared Statements. The reason is that we do not want to be distracted by differences between PHP 5 and PHP 6 at the moment. Once the missing core functionality has been implemented, we will try to port mysqlnd to PHP 5. There is no time plan for PHP 5 support, but we see the need for it.

Thanks to both Ilia and Andi for pointing out that we had forgotten to explain our PHP 5 plans in the announcement of mysqlnd!

Larry Augustin was in town over the weekend, so we met up at Deer Valley for lunch and gossip. We then spent a half-hour talking through the different licensing models available to open source software vendos, and their relative merits/demerits. (No wonder Larry's wife and daughter got bored and left. ;-)

The core question up for discussion? Is 100% free source software the best model for any software vendor? I went into it wanting to say 'Yes,' but left wondering.

First off, we identified a range of strategies/services a vendor can offer that fall between a pure support model and a pure proprietary license model. Look around at many open source companies (and virtually all proprietary software companies), and you notice, as Larry said, a …

Hey all -

Just wanted to thank everyone who has been using and testing the new Falcon transaction storage engine. Our first alpha release was downloaded over 52,000 times in January alone. Be looking for a new alpha release soon that has some performance improvements and other changes.

Also, I just started a new 3-part article series on Falcon that goes through the engine in detail, so be sure to check out part 1 on our articles page when you get a chance.

Thanks again - and be sure to shoot me your feedback (both good and bad) on Falcon.

On Tuesday our CIO, Johann-Peter Hartmann, gave a Web-seminar about security issues in the Web 2.0 era. We had about 140 participants and some very good questions in the following Q&A Session. We would like to thank you for the response and also we´d like to thank Jürgen from MySQL, our webinar-host.

We uploaded our slides as promised. To download them, click here.

If you missed the Web-Seminar you get a chance to see the recording of it here.
But be aware: It´s in german!!!

For english readers/speakers: Johann held an english security talk some time ago. Find it here
