DB Charmer – ActiveRecord Connection Magic Plugin
+1 Vote Up -1Vote Down

Today I’m proud to announce the first public release of our ActiveRecord database connection magic plugin: DbCharmer.


DB Charmer – ActiveRecord Connection Magic Plugin

DbCharmer is a simple yet powerful plugin for ActiveRecord that does a few things:

  • Allows you to easily manage AR models’ connections (switch_connection_to method)
  • Allows you to switch AR models’ default connections to a separate servers/databases
  • Allows you to easily choose where your query should go (on_* methods family)
  • Allows you to automatically send read queries to your slaves while masters would handle all the updates.
  • Adds multiple databases migrations to ActiveRecord

    Installation

    2009 MySQL Conference/Camp Videos
    +4 Vote Up -0Vote Down

    It’s been just over three months since the April 2009 MySQL Users Conference and Expo. It took a while for the files to be processed, and then uploaded to www.technocation.org, and then I found out that the online streaming was not working properly. So I started playing with things, re-encoding some videos, updating the software, but to no avail.

    Just as I was about to give up I got notification that Technocation, Inc. was accepted into YouTube’s not-for-profit program, which allows movies larger than 10 minutes to be uploaded and viewed advertisement-free.

    So then I had to upload the videos to YouTube and add descriptions.

    So with no *further* delay, here are all the videos from the 2009 MySQL Conference and 2009 MySQL Camp:

    WebStack 1.5 - Your (L)AMP Stack
    Employee_Team +0 Vote Up -0Vote Down

    Sun's LAMP support is assembled from two pieces: the L is from our Linux/GNU Support (see SunSolve entry), while the AMP comes from the GlassFish WebStack, which, in its latest incarnation includes Apache HTTP Server, lighttpd, memcached, MySQL, PHP, Python, Ruby, Squid, Tomcat, GlassFish (v2.1) and Hudson (features).

    The inclusion of Hudson is a bit of an opportunistic move (more on that in a bit), the rest comprises a well tested, integrated, optimized, and extended component

    I’m Offering Pro-Bono Consulting
    +1 Vote Up -0Vote Down

    I started my company about a year ago, but I’ve been doing consulting for a long time. In fact, my first job in the IT industry was working for a consulting firm. Before that, starting as far back as grade school, I was involved in a lot of volunteer civic and community service activities. I admire companies who get involved in their communities, or even outside of their communities, wherever help is needed.

    As part of my business plan, I’ve put in place a policy of accepting one pro-bono consulting project per year. So far, I haven’t gotten any requests for free consulting work, so here’s my public shout out to let you know what types of services are available:

    1. Speaking or Training. My specialties are things like advanced Linux administration and SQL, but I’m perfectly capable of delivering

    The Difference Between Multithreaded and Multicore Programming
    +0 Vote Up -0Vote Down

    It is no joke that computer hardware has advanced by leaps and bounds over the past decade. 10 years ago, multicore systems were expensive and high-end; today, your grandmother may have one and probably have no clue what she has!

    Alas, application software has not kept pace. The Linux OS has done a fair job at being able to leverage some of the power multicore systems offer us, but applications running on them have not. The same can be said more or less for Windows, but it’s been a long while since I did anything systems-level with Windows. But the same issues do apply, however.

    We are today with the multicore situation where we were in the 80′s and the 90′s with the multithreaded issues. Back then, CPUs grew support for multithreaded programming, but software — including some OSes — were slow to adopt.

    Hidden Features Of Perl, PHP, Javascript, C, C++, C#, Java, Ruby, Python, And Others [Collection Of Incredibly Useful Lists]

    Introduction

    StackOverflow is an amazing site for coding questions. It was created by Joel Spolsky of joelonsoftware.com, Jeff Atwood of codinghorror.com, and some other incredibly smart guys who truly care about user experience. I have been a total fan of SO since it went mainstream and it's now a borderline addiction (you can see my StackOverflow badge on the right sidebar).

    The Story

    Update 6/21/09: This server is currently under very heavy load (10-200), even with caching plugins enabled. Please bear with me as I try to

    FreeImage and ImageScience on OpenSolaris
    Employee +0 Vote Up -0Vote Down

    Although rails is a great development environment for web applications, for a newbie the deployment of a rails application can be challenging due to the myriad dependencies on various gems, native libraries etc.

    image_science is one such ruby library that provides an easy way to generate thumbnails. It is therefore quite popular in web2.0 type applications (there isn't a site today that doesn't let you upload photographs of yourself, your pets, gadgets, whatever).  It is a very simple implementation and available as a ruby gem and so easy to install. However, the real work is done by a native library called FreeImage and installing this on OpenSolaris is a little bit of work. Although, I use OpenSolaris here, the instructions apply to Solaris 10 as well if you are using ruby from
