I went to Microsoft techdays : huge 17000 visitors, 300 confs , .... C#, F#, Sqlserver 2008, cloud ...
I took part to the "Android Developer Labs World Tour" in a place called "La cantine" ( a french cafe + some chairs)
A few geeks there, a very nice event . Each participant went back home with a nexus one !
I delivered a MySQL and java pres. I had fun demoing JPA, JSF, RestFull web services on Glassfish.
But what I will definitely remember about this week is this news :
"Ken Jacobs leaving Oracle"
You will be missed by Oracle
You will be missed by MySQL community
You have been a key people of Oracle helping design the product that made all the rest possible for Oracle. You have always played fair with the MySQL community. In my previous life at Oracle I remember 7.0, 7.1 , 8.0, 8i, 9i, 10g, 11g .... You sometimes came to Paris and gave us not just the lengthy list of new functionalities but the …

So now that the decision was made we had to start to get to work. To show the customer progress and to see what I was up against I downloaded MYSQL Community and set up 3 Servers.

• One on my Vista Machine, to be accessed by the customer to see the progress. So any part finished and tested will be pushed to that server.
• A 2nd one on a WinXP machine in anothter location just to see on how the performance is over the net. After all we don’t want to find out it takes enough time to have a cup of coffe while waiting for the computer to perform a task
• And A 3rd on my Windows 7 laptop.
• And another one is planned on a Linux box at a later point.

So some of you might ask why 3 different Windows platforms? The simple answere is – That is what is mostly out there. This is to replace VFP systems run by small to medium sized companies. They have a budget. Mostly if …

In the last of our three part series on MySQL high availability we discuss the Linux Heartbeat project, and how it can be used to automate failover between two MySQL databases.

Heartbeat exposes a virtual IP address for use by the database, and manages it as well.  In the event that one server becomes unavailable, Heartbeat will  revoke primary control of DRBD from that node, hand over the IP address to the alternate node, mount the DRBD device, and start MySQL.  MySQL’s InnoDB engine will then perform crash recovery, rollback uncommitted transactions, and startup.

Visual Foxpro was a platform of choice for small and medium applications for decades. I started writing things in Foxpro when it did not belong to Microsoft yet. I believe when it was in version 2.0. In a time when there was no Windows and machines had less than 1 Mb of Ram and a 80 MB harddisk was big. Back then the concern was to keep program and data small. After all those 80 Mb on your Novell Server had to last for a few years. I had a customer back then using SBT and entering about 300 invoices/day with about 15 lines per invoice on average and back then we used about 15 MB a year to store that information…..

Fast Forward to 2010. Said customer still does those 300 invoices on average a day, SBT is long gone, but the software has grown, been updated, improved, Moved to VFP9.0. Many features added, much more information stored. Now those 300 invoices/day run up close to 2 Gb of hard disk space a year. Not a big deal with the size and …

Two new Galera presentations are available for downloads. First is from the ever famous
FOSDEM 2010 conference in Brussels, where I visited the MySQL Developers' room and
presented a 20 minute overview of Galera project. This presentation contains new 100% insert rate benchmark and synchronous WAN replication test results. Get your copy from here.

Yesterday, we presented Galera replication in MySQL University session. The focus of this webinar is to describe our replication API (wsrep API) and our patch in MySQL source code to support the API. This is MySQL oriented and quite …

On Feb 10, 2010 we've held an event in Milan, explaining why MySQL and Java are the most popular development platforms.

Our annual MySQL User Survey conducted in early 2009 showed that 57%  of those surveyed use Java to develop their MySQL applications.

My speech was all about MySQL and its usage from Java applications with various connectors. I explained the capabilities of Connector/J and Connector/MXJ, you can see relevant on demand webinars here.

After that, I moved to the usage of MySQL Cluster from Java applications, …

Amazon Simple Storage Service is designed to make web-scale computing easier for developers. If you have a medium to high traffic web application then S3 will help you to load your content faster. Here contents may be files, photos, videos or even text. Normally S3 is used for files, photos and videos. It gives any developer access to the same highly scalable, reliable, fast, inexpensive data storage infrastructure that Amazon uses to run its own global network of web sites.

3 months ago I developed a project for one of my client using Zend Framework. 1 week ago he told me to change the photo uploading system from hosting disk to amazon s3. Yesterday I implemented s3 for him and found its really very easy using Zend framework.

Here I’m describing how did I do so:

If you want to access S3 you’ve to signup in amazon s3 and need …

We're getting quite a few people now using InfiniDB and the top open source BI tools. As we're not experts in these tools ourselves, we are looking for help to do product viability testing to determine what issues (if any) we need to correct in InfiniDB to properly work with these tools. If you know one of the tools below well and are interested in tackling this type of project, we'll certainly compensate you for the time you spend. Contact me at rschumacher AT calpont DOT com.

Some technologies come on the information technology landscape and stay, providing long-lasting benefits, whereas others are more of a short term fad and ultimately end up disappearing because the value they supplied was too niche oriented and/or they were quickly supplanted by another technology that is better. Recently, articles, blogs, analyst reports, and other media outlets have been noting the rise and usage of column-oriented databases in the areas of data warehousing, analytics, and other business intelligence/read-intensive situations. And on the MySQL front, there are a couple of column DB’s that are now available for you to use.

Are column-oriented databases a technology that is destined to stay and provide long-term benefits or will it be relegated to the forgotten pile of other software that came on the scene quickly and then disappeared?

I will be presenting to the Dallas Oracle Users Group on An Introduction to MySQL : 99 Things You Probably Did Not Know on Thursday, February 18, 2010 from 4 pm – 6 pm. Refreshments sponsored by Sun. More details on the DOUG site or North Texas MySQL Users Group.
