13 February 2010 Agile Software Development

Adaptive software development processes were introduced as early as 1974 as a new way to develop software. These were called "lightweight" models but they never dominated the software industry. But it wasn't until the mid-1990s, that agile software development started to be considered as a replacement to mainstream "heavyweight" models traditionally aligned under the Waterfall model, and considerable time, money and effort taken to further develop "lightweight" models/processes.

These new models or processes such as Scrum (1995), Crystal Clear, Extreme Programming (1996), Adaptive Software Development, Feature Driven Development, and Dynamic Systems Development Method (DSDM) (1995) have recently (2001) been brought under the Agile Methodologies umbrella and an effort undertaken by 17 leading figures in the field of agile software development to codify these principles under the "Agile Manifesto".

Packaging Systems Under Linux (9 January 2010)

LOCATION: http://www.fairfaxcounty.gov/LIBRARY/BRANCHES/he/
DATE: 9 January 2010
TIME: 10am
TOPIC: Packaging under Linux

Here is a brief run down of the topics to be covered:
* Talk about Linux packages briefly, zip files, tar/gz files, rpms, and debs.
* Brief, basic usage of the above (for the wee penguins)
* How to create RPMs (for the bigger penguins)
* How to create Yum repositories
* How to deploy RPM and Yum in your organization
* Common pitfalls with RPMs and Yum repositories (what not to do, how to fix the rpmdb)
* How to create deb files and apt repositories

Bonus material:
* drpm/delta rpm
* rpm sub packages (should be simple to explain)
* rpm triggers and other advanced features

(IF you have a projector you can bring, please do so. I have not purchased one yet)

Google Wave Notes, (1) Extension Types

Google Wave in it's current release version appears to support two types of extensions:
  • Robots: Apps that run outside the wave, and are contacted by the wave (mono-directional).
  • Gadgets: Apps that live inside the wave and have shared state between wave participants.
For robots the extension libraries are predictably in Python and Java and currently only use the Google App Engine as their application server. The Gadgets on the other hand are written in HTML, CSS and Javascript, are subject to a public display condition and work primarily on the "wave" object (shared state). [personal note] This offers an interesting set of tools for a developer to create extensions, which are claimed to be first class citizens within the wave. It's reassuring that there is mention of how development has not kept to the standard API's but is mostly compatible with them. This may either mean a forking away from standards in the future,

Presentation materials from Novembers iPhone presentation by John Franklin

Here is the bundle of stuff that was presented at the November meeting including the step by step PDF. See attached file.

Objective-C Classes

If you are familiar with object-oriented programming, then you'll find Obejctive-C classes to be an easy concept to grasp. Each language has a different way of handling objects and object classes, any particular language may not support all features, but the base concepts are all similar.

Government Grants For Home Repair

There are thousands upon thousands of homeowners right now that are desperately trying to sell their homes. Many homes need extra work done to them in order to strengthen their value but for financial reasons families cannot make the necessary upgrades to their homes. The government already understands this predicament that many are faced with which is why government grants for home repair has been instituted.

Government grants for home repair were designed to assist homeowners who basically do not have the financial resources to make very necessary upgrades on their home to hopefully cause their home to sell. There is already a plethora of foreclosures in the US market so it is to the homeowners benefit to take advantage of government grant money so you can hopefully sell your home.
