It’s time again for WordCamp San Diego 2012. Sat Mar 24 and Sun Mar 25 will be two days filled with WordPress geeky goodness, a full conference on Saturday and a developer hack day on Sunday.

I’m speaking in the Developer track on Saturday at 2:10 pm—my topic is Theme Busters R Us:

Breaking themes for fun?! Crazy talk. Busting your WordPress theme–on purpose–can be both fun and useful. The process is a crucial part of building sites with WordPress, whether it’s for a client project, a personal blog, or releasing an awesome new theme to the world.

See the rest of the talks on the full Saturday schedule; there are two tracks to choose from (End User, Developer) with great speakers and topics.

If you’re not at the event you can still join in, the talks will be live-streamed. Check the WordCamp San Diego 2012 website for details.

The overall topic was the Open Web. Understanding its history, key technologies, and important concepts. Molly presented over two full days, with interludes and additions by special guest Kimberly Blessing (who also took photos).

Even considering myself an industry veteran—I’ve worked full-time on the web for over seven years, I learned new things and solidified several of my weak areas. I highly recommend this workshop to anyone who works on the web. And, Molly organized the weekend on her on time—and her own dime. Thanks Mols!

Here are my notes from the sessions.

Open Web

Preserving the infrastructure of the web so it remains open to everyone.

What is the Open Web?

1. Dedication to open standards
2. Use of technology should be unobtrusive
3. Recognition of the web as an application and document platform
4. Encourage open, organic groups such as WHAT-WG and microformats.org

Groups like these extend what is coming from W3C to begin implementing things faster, and start using technology now.

Making research and development part of your process—part of your team workflow—keeps a conversation open. We are serving a much larger future.

Core principles

Transparency and authenticity

From a browser vendor’s viewpoint this means allowing dev previews, blogging about changes. IE (Internet Explorer) is doing a great job with this.

Connectability via APIs

JavaScript (JS) is the most-used programming language on the planet. You get a JS compiler, interpreter on almost all devices.

Open specifications

These things need to go through the patent exclusion process.

Error forgiveness

Allow people to make mistakes.

Additional thoughts to go with core principles.

Freedom of Social Forms—an idea coined by Brad Neuberg from Google. Look at things beyond what they are or are not.

The [Open Web] is big enough to support many forms of social and economic organization, including ones we haven’t imagined yet.

The Many Things Rule—an approach to a problem with a broader perspective. Something you make can be used by other people and for other applications.

User experience (UX) and front-end development are key skills for working with the Open Web.

Core technologies

- HTML5
- CSS3
- JavaScript

Also discussing:

- video and audio
- Visual technologies: canvas and SVG

Under the JavaScript umbrella are things like XmlHttpRequest (XHR), what we now know as “Ajax” (note the spelling). Originally conceived by Microsoft to allow Outlook for the web.

HTML

History lesson first. WHATWG first came out as a grassroots movement, with Ian Hickson (was at Opera, now at Google). It was the first time that all major browser makers agreed on a single spec: HTML5. The working group had 800 invited experts!

Recently, Ian’s announced it’s no longer known as “5″, saying it’s a living standard. It’s more mature than any version of HTML, and no longer a draft.

He stirred the pot, recently, with the (now reversed) decision to remove the time element in favor of data. Molly mentioned all the jokes that sprung up around this. One web dev says to another, “Say, do you have have the “? One guy, scarily, making changes and everyone is letting him.

Molly defines HTML5 like this:

HTML5 is a vocabulary and set of application programming interfaces that make up a core declarative language for web sites and web applications.

Pop quiz! What is the only required element for a valid HTML document? title element. Because HTML is based on SGML, the rest was added later to be declarative and provide structure for layout.

HTML5 design principles

1. Support existing content
2. Ensure interoperability
3. Define user agent (UA) behavior instead of leaving it open for implementors to interpret for themselves. Best practices come from real world usage.
4. Better error handling
5. Evolve, not re-create

A fun mollyquote:

The Open Web is threatened by the three As: anarchists, Apple, and asshats.

application/xml MIME type was not supported by any version of IE, until the most recent version—after XHTML was already declared dead. Oh, the irony.

Avoid XHTML5 (which is just plain stupid). What it should be called is XML+HTML. It’s used mostly for internal projects by people who want facilities that come with HTML5 but need to serve XML.

HTML5 Media APIs: goal is to replace plugins with native solutions: video, audio.

Molly here discussed the H.264 codec war. It is not an open or web standard, it carries a $5 million/year cost. Alternatives include OGG (considered unencumbered, “probably, probably never going to get sued for rights”).

Another mollyquote:

At Opera we called it H.666

[Lance side note: Molly mentioned OGG being developed by Thomas Dolby. I didn't see any mention of his name at http://en.wikipedia.org/wiki/Ogg.]

Video progressive enhancement means using the video element with H.264, OGG, WebM, and Flash as the last fallback.

canvas

It’s bitmap (not vector), great for 2d animations and games. You design with JavaScript. Immediate mode versus retained mode, meaning instant gratification. Used and abused for text-shadow and special details that are totally irrational. Not built as a web element (came out of Apple)

SVG

Far more accessible, vector-based. Good for interaction, shapes. Allows access to the DOM. Google indexes it.

Other technologies related to HTML5

Device-related APIs, Wholesale Applications Community (WAC). It’s like the open web for mobile.

HTML outlines

[An interlude by Kimberly.]

In HTML5 each of the sectioning elements starts a new tree. section, article, aside, nav. You can start again with an h1 as the top-level heading inside of each sectioning element.

Understanding divisions versus sections. section is *not* a replacement for div. div still has meaning (which is “null”). It’s a division. section is different because it changes the document outline, div does not.

(More info)

CSS

Molly says this is a “polyfill class”—filling in the gaps in our understanding, making sure we know the correct terms and definitions. Using the terminology is super important, a team should use a shared terminology.

History lesson: 1994 saw the beginnings of CSS, based on print technology. Hakom Lie and Burt Vos came to the W3C, they were document specialists and from the print world.

CSS rule structure

selector {
	propery: value;
}

The code within the braces is the declaration block, property value pairs are declarations. In CSS, rules are the basic building block

Important note: inheritance != cascade. [Lance note: I am often confused on this point.]

Inheritance is the document tree: ancestors/parents/children. Any property that is inheritable will be applied down the tree until another rule overrides it farther down the tree.

Cascade answers the question, “What is the origin of the style?”

1. Browser (user agent)
2. User
3. Author
   1. Inline
   2. Embedded
      1. Imported
   3. Linked (external)

Quick !important story. It used to be the other way around in CSS1, user styles came last in the cascade.

Reset method puts the author in control, makes the user agent styles a level playing ground. Linked stylesheets: leaving the media attribute out, it defaults to “all.”

Sort order within the cascade: inline, embedded, author. User styles override browser (but not author!). Rule: closest to the content overdrives other rules (after specificity is calculated). But !important in user trumps !important in author.

[Lance joke interlude: is the best way to classify a raunchingly humorous site.]

pseudo classes are things like a:hover and a:focus.

The “combinator” is the selector symbol used to denote the relationship between the selectors.

- [space] descendant
- [>] child (only down one level)
- [+] adjacent sibling
- [~] general sibling

Complex examples can be solved by the “nth child” selector, like table striping. Adjacent sibling combinators are great for “when these two occur together” and make them appear differently.

[Interlude: clearing floats with overflow]

Kimberly says you don’t need a width on the parent element. If you have overflow: hidden; you can sometimes get a scrollbar when you see an outline on the element; to get around it add padding-bottom: 1px;.

Overflow to clear floats is not a hack, it’s right from the spec.

[Back to CSS.]

Pseudo-elements like :first-line, see also generated content with :before and :after. Nice use would be an href display for print CSS, to show the full URL on the printed page.

We should all learn about how browsers work: re-render, re-paint, re-flow.

Positioning

- relative is “offset”—it’s calculated relative to itself, in the normal flow, the content does not move up to take its place in the flow.
- absolute is taken out of the flow, now placed according to the nearest positioned ancestor (the ancestor does not need any offset, just a position propery), or the root element in the tree (HTML element).
- fixed is out of the normal flow, placed according to the viewport. This was not supported in IE6.

Coming soon to CSS:

- The flexible box model
- Multiple columns
- Template-based layout
- Grid positioning, “snap to” idea of placing elements

See Jina Bolton’s work with template-based layouts.

Random notes from the workshop

“Web project manager” needs to be a named and defined role; it’s the missing piece in web production teams … aka Tech Lead.

We’re in the era of dev ops, everyone needs to know the full stack.

Important note: jQuery != JavaScript

The best interface for web APIs is HTTP + HTML. Send a web page, let the receiving service parse it.

What is ontology? A vocabulary. Molly mentioned OWL; XML languages for each industry, “Web Ontology Language”. (Wikipedia)

Photos

Kimberly took a few photos at the workshop: Web with Molly on Flickr. Including the featured photo shown for this post—thanks Kimberly, for being a part of the workshop.

That’s right folks, WordCamp Phoenix is coming up this weekend, Fri Feb 24 through Sun Feb 26. Three days of WordPress geeky goodness, including full-day workshops on Friday, the conference on Saturday, and an “unconference” on Sunday.

I’m speaking in the “Jumpstart” track on Saturday at 10:30 am—my topic is Navigating the Theme Landscape:

Learn what types of themes are out there, how to find and choose a theme, and dive into basic modifications to your theme so it fits you perfectly.

See the rest of the talks on the full Saturday schedule; there are three tracks to choose from, and lots of great content.

I’ll also be working the help bar Saturday, from 2:15 pm onward. Come say hi!

Let’s talk WordPress, Arizona. More info: http://2012.phoenix.wordcamp.org/

Update Feb 26: Slides and links to all the themes and resources I mentioned are here: http://themeshaper.com/jumpstart/

Update Mar 8: The video of my talk is now online at wordpress.tv: http://wordpress.tv/2012/03/08/lance-willett-navigating-the-theme-landscape/

Using WordPress to blog, to publish, to communicate things online that once upon a time would have been relegated to an unread private journal (or simply remained unspoken, uncreated, unshared) makes you a part of one of the biggest changes in modern history: the democratization of publishing and the independent web. Every time you click Publish, you are a part of that change, whether you are posting canny political insight or a cat that makes you LOL.

Help Stop SOPA/PIPA

I work there once a week—usually on Friday—and love the quite, productive atmosphere, fast WiFi, and the ability to connect with like-minded individuals (learn more about coworking). It’s also within walking distance of three areas: Downtown, 4th Avenue, and University Boulevard, all of which offer great choices for lunch or a post-work happy hour.

You should come try it out if you live in the area. Your first visit is free!

Spoke6 also hosts Tucson Digital Arts Community events, including the Tucson WordPress Meetup which I host once a month.

• Introduction to HTML5 on May 19th, 2010
• WordPress Meetup on May 25th, 2010

I’m particularly excited about the “Introduction to HTML5” talk since it’s my first time co-presenting with long-time friend and former coworker Aaron Wagner. I will cover new features in HTML5 and CSS3 while Aaron will talk about the new JavaScript APIs and browser extensions. Plus, he’ll give us a demo of an HTML5 application called “Times Up” that he built for his church. Can’t wait!

Join me and the Tucson Digital Arts Community for an evening of WordPress discussion.

In a nutshell: we’re inviting civic-minded coders, designers, and others interested in using their skills to make Tucson a more livable community to come together to create apps that can make a difference.

I would encourage you to come to the kick-off meeting. There are a variety of apps that could be built as part of the hackathon, so there should be a chance for everyone to get involved.

I know some of you have asked—I know I have—for more technical meetups and “hack days” in Tucson. This is the perfect chance to be a part of something that will satisfy your itch to hack on a project together. And, more importantly, it is a great chance to get involved in improving your local community.

• RSVP for the event

Hope to see you there!

Local web ninja Jared McFarland summed it up nicely in Capitalizing on the Tucson Tech Community.

We, as a community, can work together to educate and inspire one another. We can enjoy the same benefits as the people in major tech centers simply by knowing each other and inventing ways to work together. It isn’t about vast numbers of people, but small passionate groups. The web brings like minds together globally, but we can now use the web to find each other and act locally. We can turn Tucson into something intentional, and beautiful, for ourselves and the city.

The larger Tucson community is also bubbling with social events like Ignite Tucson and the myriad of Twitter meetups (“Tweetups”). Just search Twitter for #tweetup #tucson to be amazed. These events cover a much broader range of topics than web design and development but they all share a common goal: to mingle, network, and share with others.

This is how I think it breaks down: socially, the larger community wants to meet itself and technologically, web designers and developers are joining together to improve the tech community. All of this energy and enthusiasm is contagious!

In contrast, I want to share the story of the Tucson Geek Meet¹, a group I was personally involved with for four years. Started as the Tucson Web Standards Group in 2003 by Molly Holzschlag, the Geek Meet slowly lost momentum over time. Instead of growing and expanding, it stayed a small core of five or six people.

Don’t get me wrong, because of those meetups the five or six of us are now steadfast friends, and several of us have had the opportunity to work together. Now that we are friends we can socialize anytime—we don’t need to call it anything. The idea of the Geek Meet isn’t going away, it’s just being replaced by ad hoc Tweetups and other social happenings around town.

What I want to encourage, and I think Jared hit on this, is not just the social aspects of meeting together but the educational and inspirational benefits of sharing code, experiences, and real-life examples of our work. TDAC is spearheading the effort by organizing workshops and collaborative coding days to get people together to educate, inspire, network, and improve. I’ve been a part of TDAC for six months now, and the tech community in Tucson isn’t just soaking it up, it’s clamoring for more.

We’re hoping soon to have a Refresh Tucson—our neighbors in The Valley have had a strong Refresh presence for three years—we can do the same here in the Old Pueblo. So please participate: join up, tweet up, meet up, share, and pass the word to your colleagues and friends.

Let’s do it, Tucson.

How to get involved

Notes

¹ The Tucson Geek Meet is no more, it’s pushing up the daisies, it’s kicked the bucket. This meetup is not pining for the fjords, it’s gone to meet it’s maker. It’s… OK, enough of the Monty Python!

For posterity, here is a brief history of the Tucson Geek Meet:

2003(?): Started by Molly Holzschlag.

2005: Tucson Web Standards Meetup moved to Upcoming by Lance (from Meetup.com). We met at B-Line and Famous Sam’s. See Molly’s 2005 post and my 2005 post as well as the Upcoming group page.

2006: Met monthly at the Old Chicago patio. A few Flickr photos from 2006 events: Great Discussion at Tucson Web Standards Meeting, Geoff in Action.

2007: Changed the name to Geek Meet.

2008: The infamous Hooter’s incident. D’oh! (Yes, Molly gave us a good lashing for that, and it was deserved.)

2009: Called it quits in favor of other local groups and Twitter meetups.

This post was originally titled “Rest in Peace, Tucson Geek Meet” but I decided that it was just a small part of the burgeoning Tucson web design and development scene.

I have one (1) registration for SXSW Interactive 2009 available for sale at a discounted rate. Since I purchased it early (last September) the face value is $375, which saves you $75 over the rate if you register before February 13, 2009—and $120 over the walk-up rate.

By SXSW rules I can transfer it to another person, so please contact me if you are interested.

(Why is it for sale? I planned on going this year, but am now unable to attend.)
