News & Notes

Computer people just love to name things.   The server guy who names all his machines after Star Wars characters competes with the network guy who names all his routers and switches after Star Trek characters to see who has the more obscure references.  Usually the Desktop guy wins with his collection of Windows PCs named after Transformer characters, but that’s beside the point.  It sounds like it is all in fun, but there is a very important reason we all do it.  Technology is hard for humans to relate to.  It is cold and lacks personality.  Names help give definition to the undefined. They help give things context.

Programmers, being computer people,  really get into the naming of languages and processes.  I’d like to take this post to identify and briefly explain some of the terms you may have heard your programmers using.

Agile development

If San Francisco could be considered not just a place but a lifestyle, Agile development would have a similar vibe in the programming world.  Typically it refers to the 12 guidelines people in software teams follow when working together on software projects, though there are widely different ways to actually put those guidelines into practice.  The ideal behind an Agile development team is that it is small, it meets all the time with each other and with the clients, and it writes code in small chunks that the customer sees working every couple weeks.  Agile was a reaction to the inflexibility of older programming procedures that didn’t allow the customer any flexibility to change their mind late in the delivery cycle.  Since customers are constantly rethinking their needs, Agile was developed to allow the code to change with the requirements.  Below are the 12 principals of the Agile Manifesto.

1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
2. Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.
3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
4. Business people and developers must work together daily throughout the project.
5. Build projects around motivated individuals.  Give them the environment and support they need, and trust them to get the job done.
6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
7. Working software is the primary measure of progress.
8. Agile processes promote sustainable development.  The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
9. Continuous attention to technical excellence and good design enhances agility.
10. Simplicity–the art of maximizing the amount of work not done–is essential.
11. The best architectures, requirements, and designs emerge from self-organizing teams.
12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

Scrum

HR, Sales and Accounting may have meetings, but only programmers can take the basic idea of getting together in the same room and rename it a ‘scrum’.  Borrowed from the term used to describe a huddle in rugby, a scrum is a highly organized, short daily meeting of all people involved in an agile project.  It has the singular goal of keeping people focused on the project, which is really important since a ‘sprint’, or stretch of time allotted to write working code, is usually only two weeks.   Guidelines for scrums can sound harsh, only three questions are asked, everyone should remain standing, only people with a stake in the project should speak, but it was invented in direct contrast to pointless time-wasting mega-meetings that the Dilbert comic made an empire satirizing.

Extreme Programming & Test Driven Development

Who wouldn’t want to work on an something with the word ‘Extreme’ in it, huh?  Extreme Programming (XP) is very similar to Agile, or it might be more accurate to say that it is a good case study of Agile programming before there was such a term.  The real big take home from XP that sets it apart is its absolute devotion to the idea of testing.  Now, as a lil programmer, I thought testing code was for suckers who worked government jobs.  Then I was turned onto the wonders to full stack testing and how it changed my whole outlook on my craft.  Testing is really the only way to write Enterprise ready code.  Some guys saw that if you wrote your tests first, then wrote code that made the tests pass, your applications would have fewer bugs.  They called it Test Driven Development (TDD).   Turns out testing is becoming the rock star of the programming world thanks to web frameworks like Ruby on Rails and Symfony having it baked into the package.

This post just scratched the surface of the terms programmers (and computer people) love to throw around.  If you know of a term that you want a little help with, add it down in the comments and I’ll try to reshape it into something that hopefully makes more sense.  I’ve been known to use puppets with clients before, so anything’s possible
