Adopting RAD in the Enterprise: The 14 Biggest Misconceptions
+0 Vote Up -0Vote Down

Rapid Application Development (RAD) is a way of developing computer software applications with less effort than the traditional means.

RAD tools focus on providing code generation and automated testing capabilities with the use of convention over configuration to provide a streamlined workflow to create applications.

Even with the most advanced and easiest to use RAD tools, there are times which the traditional enterprise and the business software development vendors which are having their own implementations and in-house built frameworks are continuously refusing to adopt them.

Most of the misconceptions on the RAD are based on FUD (Fear, Uncertainty

Cloud, SaaS and The Consumerization of IT
+2 Vote Up -0Vote Down

I wrote a guest column for GigaOm on how open source software, cloud and software as a service are helping to bring about the consumerization of IT: namely bringing simplicity where complexity reigned.  I cited some examples including New Relic, Box.net and Apple.

Open source has gone a long way toward putting power back in the hands of developers, who can download, install and deploy software without having to go through any kind of convoluted sales or budget approval process.  You want MySQL?  You can download and install in

    How Real is the Data Deluge?
    +1 Vote Up -1Vote Down

    It seems obvious that given the decreasing cost of storage and computation, there's going to be a significant increase in the volume of data that organizations accumulate over the next 10 years.  But the type of data being accumulated may be different from the areas where traditional DBMSs dominated.  It's not just about transactions; it's search patterns, on-line behavior, click-thru data, events fired off by smartphones, messages over Twitter & Facebook, log data of various kinds.

    If an organization can figure out a better way identify prospects, or deliver more targeted ads, or optimize pricing decisions by analyzing terrabytes of data, they'd be crazy not to. Over the long term, companies

    Following High Performance MySQL’s hash index discussion
    +1 Vote Up -0Vote Down

    Mixing up some MySQL and SQL Server hacking activities can be fun. I’ve also noticed that when you work with different database platforms, it can bring additional clarity to certain concepts and techniques. One reason for that, I think, is that different terminologies and ways of explanations are used for people practicing on different platforms, and that tends to re-enforce or otherwise bring clarity to things that you may not have a good grasp to begin with.

    Anyway, I am following Baron Schwartz et al’s High Performance MySQL book and thought the example of building your own hash index for URL lookup looks really useful and clever. On the topic of hash collison, the book discussed using words in

    Generic indices in GenieDB
    +0 Vote Up -0Vote Down

    We’re gearing up to release v0.5 of GenieDB right now, and the biggest new feature in v0.5 is the generic indexing framework.

    Originally, GenieDB provided indices on fields of records. As we do not mandate a per-table schema, each record in a table could have totally different fields; so when an index is created on the field “foo” of the table “bar”, we index any record in “bar” that has a “foo” field under that value in the index. If the record did not have a “foo” field, then it doesn’t appear in the index at all (whereas records with a NULL value for “foo” are indexed under NULL, of course).

    However, expecting future interesting developments, we made sure this part of the code – figuring out how a given record should appear in a given index – would be easy to

    Testing Windows IO with SQLIO and SysBench
    +1 Vote Up -0Vote Down

    To benchmark IO on Linux and MySQL transaction processing, SysBench is a popular choice that can do both. After poking around at the source code, it seems PostgreSQL and Oracle are also included for transaction processing testing if you have the proper header files, but I didn’t test those.

    To benchmark IO on Windows and SQL Server transaction processing, Microsoft provides two tools, SQLIO and SQLIOSim. SQLIO is a misnomer in that it really doesn’t have much to do with SQL Server. It is a general purpose disk IO benchmark tool.

    So today I was playing with SysBench and noticed that I can compile and build it on Windows as well. I decided I should run IO benchmark on a single machine with both tools (SQLIO and SysBench), and see if I could reconcile the results.

    To make things simple, I thought I would just benchmark random read of 3G

    Having fun with MySQL and Python: converting MySQL character set to utf8
    +0 Vote Up -0Vote Down

    Lately I worked quite a bit with Python and Linux, writing monitoring and automation utilities. I am in a transition period, so I thought I ought to write some Python stuff interfacing with MySQL for fun, and start positioning myself for expanded career horizon, I hope.

    To get started, I thought it would be fun to rewrite a Perl utility I wrote before with Python. That script converts MySQL character sets to utf8, a very common task for wikis and blogs during an upgrade. This time, I did everything from scratch: firing up an Amazon EC2 Linux instance, hand install and configuring MySQL 5.1.50 (creating mysql user, group, wget tarball, setting directory ownership and permissions, creating symbolic to MySQL binaries, editing my.cnf,

    Do We Need a New Programming Language for Big Data?

    I'm the boards of two companies (Pentaho, Revolution Analytics) that are starting to see a lot of customer traction around Big Data.

    iPhone 4: First Impressions

    I managed to get an "early upgrade" of my iPhone 3GS to the iPhone 4 despite AT&T's best efforts.  I've had a couple of days using the new iOS 4 operating system on my 3GS and a couple of hours with the iPhone 4.  So here are a few highlights of the initial hands-on experience with more updates on the weekend.

    XAMPP – Where have you been all my life?
    Employee +0 Vote Up -1Vote Down

    I love Wordpress.  Really there isn’t a better blogging platform on this platform.  It’s that good.  And I’ve been using it to self-host my blog for the past year or so.  For awhile, I hosted it using II6 on WHS v1.  That was a real pain as it took several days to find a URL rewriting solution that worked with IIS6.  The past few months I’ve been hosting it on my Windows 7-based media center.  Since that runs IIS7, URL rewriting was easier using the standard URL rewrite module.

    A few days ago I decided to test out WHS “Vail”.  After installing it, I wanted to move my blog onto it so I downloaded the Microsoft Web Platform Installer.  It promptly let me know that it couldn’t find any products in my selected language.  Huh?  This is what drives people crazy about Windows software.

    MySQL 5.5 Performance Gains
    +3 Vote Up -4Vote Down
    Oracle managed to score a major victory last week at the MySQL Conference by announcing performance gains of 200-360% in the forthcoming version 5.5.  This is a tremendous improvement and comes in part due to closer collaboration between what were historically two distinct (and occasionally competitive) groups: the InnoBase team and the MySQL Server team.  Bringing the InnoBase team under the direction of the MySQL Server team under Tomas Ullin is a great benefit not only to MySQL developers, but also for MySQL users.  No doubt these performance gains are a result of many months of hard work by not only Tomas, but also a good number of folks on both teams including guys like Mikael Ronstrum, Kojstja, Calvin Sun and others.

    Tracing changes in MySQL Connector/Net 6.2 – Part 2
    Employee +3 Vote Up -0Vote Down

    In our last installment we found our hero investigating the tracing changes found in Connector/Net 6.2.  This time we’ll take a closer look at the format of the trace data and how developers can use that information to write new and interesting trace listeners.

    Understanding the plumbing

    The first thing we need to understand is a little about how the trace messages are routed.  The main method we are interested in is TraceSource.TraceEvent.  Here is the signature.

    public void TraceEvent(
        TraceEventType eventType,
        int id,
        string format,
        params Object[] args
    )

    Tracing changes in MySQL Connector/Net 6.2 – Part 1
    Employee +5 Vote Up -0Vote Down

    For years, Connector/Net has been a key part of any MySQL & .NET developer’s toolbox.  Tracing is also a key part of a developer’s life and Connector/Net has always output trace messages. 

    This first post is a review of .NET tracing systems and how we changed our trace output.  The second post will cover how developers can use the new tracing format to develop new applications.

    Tracing in .NET 1.x

    .NET shipped with a very simple tracing system.  You have a static class named Trace that has static methods such as Write and WriteLine.  An application can use code like the following to output a message to the trace log. 

    Now that we have output our message, how do we direct it somewhere?  You do that with listeners.  There are a few standard listeners included in the framework
