Child themes are a piece of cake to create, and a child theme lets me override the original without messing with the original source, so updates will not erase the changes. While they are not so difficult to do manually if you are familiar with the command-line, they are even easier with the plugin One-Click Child Theme.

With the child theme in place, I was able to shorten the gap between the site description (the motto) and the header picture, just by adding CSS to the style.css in the child theme (that’s the cascading part of CSS). I added a paper-curl edge effect based on the work of Craig Buckler, published on Sitepoint.

I was disappointed that my site was not valid HTML5, according to the W3C’s validator site. Category tags used in REL links aren’t standard, so I deleted those. The Creative Commons plugins want to use Dublin Core XML namespaces, and there are issues there I’ve got to clean up. And the “generator” REL tag on the bottom of the page isn’t too standard, either. Overall, though, the pages are relatively clean of excessive markup or poorly-formed structures. Stay tuned as I tweak the last few elements into line.

Can't decide if these are palms or Dr. Suess' truffula trees

L pointed out the curious frost that formed on the windows overnight in the sub-zero weather. I can’t decide if Jack Frost was dreaming of palm trees or Dr. Suess’ truffula trees.

Organizer Brian Turnbull got the meeting started with brief introductions.

Clients want the improved client-side experience of rich-client apps within the browser.

But which framework? Different patterns: MVC2 is what we’re used to seeing in Ruby/Rails. MVC and MVVM (Model-View-View-Model or Presenter).

Choice fatigue (http://www.nytimes.com/2011/08/21/magazine/do-you-suffer-from-decision-fatigue.html) : there seem to be more JavaScript frameworks than JS developers.

• Capuccino – PowerPoint in the browsers, 270North
• SproutCore (1,x,m 2.z) ricu Ui widget framework,.0 from the ground up rewrite, less widgets
• Knockout.js: useds the HTML5 Data- elements
• Batman.js – from Shopify, ActiveMerchant, using Node.js server-side component
• JavaScriptMVC – mature, uses jQuery, filterable grids, lots of power
• Spine.js – CoffeeScript, asynchronous front end, does full validation on client-side
• Backbone.js – tonight’s featured framework, well-documented (in Doc-O)
• Angular, Coherent, PureMVC-js, AFrameJS, TrimPath Junction,

Moving parts:

• History
• Router
• View
• Model
• Collection
• Sync
• Underscore
• $

Jason wowed the crowd with an excellent demo of an app under development and spoke eloquently of the power, and the dangers, of deploying MVC (or MV-something-else) into the client. His slides contained a great many good references. My laptop gave out at this point, so I didn’t take additional notes, but you can find his slides at http://jayunit.net/backbone-js-on-rails-talk and source for the slides at https://github.com/jasonm/backbone-js-on-rails-talk/blob/gh-pages/slides/index.md

One of the little things that got the crowd all excited was the line numbering on Jason’s Vim session: the current line was numbered 0, and line numbers incremented both up and down the screen. “Oh, that” Jason said. ‘set rnu’ is the command (see :help rnu within vim for details.)

Michael Tomer talked a little bit about his project, rocket.io, which is an interesting project trying to solve similar problems: “real-time” (no http lag) page updating, background sync between client and remote server. You can find his work at http://actsasbuffoon.com/rocket-io/

Thanks to Jason for an awesome presentation, to Nick Plante for hosting us at AlphaLoft, to Brian Turnbull for organizing the meeting, announcements and logistics, and to all the attendees for their participation.

Brian presented an introduction to Rails 3 using a small application he had built for  work. He gave us an overview of the problem to be solved, skipping the irrelevant details, and explained how that fit into basic MVC concepts. We touched on the idea of design patterns. We examined or discussed many facets of Rails development, including rake tasks, migrations, fat models – thin controllers, using HAML for view templating, creating your own custom validators, deployment using Capistrano and more.

Brian mentioned several useful resources, such as Google, the Rails Guides, the API reference,  and more. He mentioned that he’d read Metaprogramming Ruby and thought that it changed his perspective on using Ruby.

As always, there was time for folks to get their questions answered. There were questions on stack dumps in rake, unobtrusive JavaScript, new features of Rails 3, Capistrano deploys to non-git-clients, and more.

Thanks to Brian for a information-packed presentation, and to all for attending and participating. Brian is always looking for ideas for future meetings and volunteer help in organizing.

Dave – former Cold Fusion, ETL, new to WordPress,
Carl Eric Johnson – web developer, WordPress instructor and eveloper, fan of Thesis framework.
Amanda – BIL doing Joomla, Drupal, and WordPress
Sharon, Rye Public Library, Technology Coordinator, just launched a freshened site on April 1st using WordPress and Atahualpa theme/framework.
Will, a graphic designer in a print shop who’d been encouraged to learn web design and now WordPress.

Book recommendations:
Amanda praised the Wrox Professional WordPress book.
Eric has enjoyed WordPress: Visual QuickStart Guide to get up and running, and WordPress Bible(Aaron Barzell) from Wiley as a reference.

Main Presentation: Carl Eric Johnson: talk about themes and frameworks
Sitepoint.com Wicked WordPress Themes book has free sample download chapter. Table of contents points out the choices of custom themes, child themes, building a framework.
Child themes: load with parent’s theme files, in your child file, you import the parent, then override what’s different.
In WordPress 3.0, theme TwentyTen has a lot of options built in. Thesis and Atahualpa have a number of pages of options: sizing, features, colors, styles, etc.

Amanda talked about file structures and “the loop” – directories of wp-admin and wp-install are pretty much off-limits, containing the installed WordPress files and overwritten up updates; wp-content contains most everything else, including the stuff you customize. Add your own functions.php and copy the functions you want to override. A theme consists of index.php and style.css as a minimum; you can add as much as you want from there. See the Codex for the hierarchy of theme files WordPress looks for in order to render your content. Consider starting with a “blank” theme if you’re building your own, such as Starkers or Boilerplate themes – essentially stripped-down skeletal themes with all of the style removed.

See http://codex.wordpress.org/Template_Hierarchy for a description of how WordPress selects the correct template(s).

See http://codex.wordpress.org/The_Loop_in_Action for an overview of the loop.

Tick, tick, tick...

So, if I don’t I don’t do any networking for 136 years, …

Signed integer, unsigned integer, what’s the difference? Happy April Fools, folks.
