RoR Database seeding

Lately, I’m researching various RoR methods, technologies, and doing further ready on Agile software development methodologies. Below is a technique I’ve learned for seeding RoR databases.

    Database seeding technique

  1. Define the model and controller (nifty_scaffold is great for building quick, CRUD interfaces)
  2. Add data to the database via the CRUD interface
  3. Use sqlite3 command to extract the new seed data into a flat file.
    In this example, the table contains custom fields for name and description.

       cd [project folder]\db
    
   sqlite3 development.sqlite3

MIT Coeus – independent build #1

Standalone – MIT Coeus Build #1

Yesterday marked my first success in doing a stand-alone compile of MIT Coeus, version 4.3.7. Of note, while upgrades must be run separately for new revisions (ex 4.3.1 to 4.3.2 to … to 4.3.7) for schema changes and SQL commands, the Java source (which comes in the same archive) is a complete replacement. Unpacking (ex 4.3.1 to 4.3.2 to … to 4.3.7) into the same source folder and then trying to do a build is asking for problems.

These following doc aws helpful in getting Java code signing and the local keystore configured.

Investigating screen-scraping options

Today, I’m investigation screen-scraping options in order for a Ruby on Rails front-end to communicate with a legacy, IBM mainframe application, via terminal emulation and screen-scraping. The purpose of this research is to see how easily a new system could do live queries (and updates) in the legacy system, without having to go batch or open up the legacy system.

Testimonial – Ashley Grayson @ Criteria

“I’ve worked several times with David where my clients needed serious, deep, software engineering effort. This has ranged from Mac OS X system level drivers to re-engineering an entire corporate website in JSP to be secure, reliable, and maintainable. David is both formally educated in CompSci and a fearless code maven AND he wears a suit! I’m instinctive at locating where software falls short of user needs or business purpose, but when we need to know what the code does,
