Things learned from Wordcamp 2012

I attended most of the developer track presentations at Boston’s Wordcamp 2012. I learned about some interesting tools and techniques that I’d like to document for myself and others.

Talk Optimizing for Speed by Ben Metcalfe

  1. YouGetSignal’s Reverse IP Lookup – Shows you how many other hosts live on the same IP Address. This can be helpful for anyone using shared hosting or maybe VPS.
  2. Debug Bar – Get debugging information from each page WordPress page load.
  3. Google XML Sitemaps – Delete this plugin if you have it. (I had it.)
  4. YSlow – Get load times and optimization tips of a page request.

WordPress as a Web Framework by Sam Hotchkiss

  1. MVC frameworks for WordPress
    1. WP MVC – Provides a singleton object and eliminates the metadata bottleneck by providing tables indexed by post IDs.
    2. Tina MVC
  2. _s Theme – Use Automattic’s Blank Theme as a good starting point.

Automating frontend workflow by Aaron Jorbin (blog post, slides)

  1. Autojump – Jump to frequently used directories
  2. Commander.js (nodejs) – Script working with CLI
  3. watch (nodejs) – Watch files/dirs
  4. mockjax – Fake your ajax calls (good for protyping or testing un-related, yet dependent functionality)
  5. Travis CI – continuous integration service (wordpress plugin tests)
  6. Glue – generate css sprites

Microdata for SEO by Dave Ross

  1. Add itemprop, itemscope, etc to any identifiable schema
  2. Google Rich Snippets Tool – Test your microdata
  3. Examples: SiteNavigation element for navigation, Blog element for blog posts, etc
  4. Some quick tidbits: Bing rates sites with microdata higher than sites without, and Google uses the microdata in search results

Enterprise WordPress by Jake Goldman (1up)

  1. Sites to show clients: showcase, WordPress VIP
  2. Maintaining a beautiful WordPress admin

Shortcodes by Jon Bishop

  1. Use oembed rather than plugins to support embedding media from sites like youtube, facebook, etc

Codex by Erick Hitler

  1. Use santize_* functions to save to db: santize_text_field(), sanitize_title()
  2. Use esc_* functions to show data to user (esc_url_raw() is the exception, it is the opposite of esc_url())

Javascript hooks by Luke Gedeon (1up)

  1. Javascript custom events are coming, they will provide functionality similar to WordPress’ action and filter hooks (list of hooks)

SMF2 Gallery2 Integration Problem

I have a SMF2 forum site, where the gallery is implemented through Gallery2 using Oldiesmann’s SMF + G2 Integration Project.

For 2 years, I’ve had the SMF and Gallery work properly together with linked member groups (a mod option), such that member groups auto-synchronized with ones in Gallery. At some point, either with a Gallery or SMF upgrade, users reported that the Gallery part of the site threw cryptic security warnings for non-admins. I explored the issue and figured users were missing in two required groups “Everybody” and “Registered Users”. I had reported it to Oldiesmann, but he claimed he had no control over those required groups and Gallery was self-managing them.

After about a year, I delved into the code and found that in order to sync the groups that a user had in SMF with the groups that a user had in Gallery, the integration code was removing all groups and adding the shared groups. This of course meant that the user was being removed from the required groups: “Everybody” and “Registered Users”. Users with privileged groups did not see the problem.

Here’s the fix that I’ve also submitted to Oldiesmann. But his forum complains when I added the code, so I had to create this post here. It says it does not allow external links (haha).

My fix will ensure that we do not remove the user from required groups and also add the users back into required groups (if necessary). Please note that the cleanup code is necessary because anyone who has ever visited the buggy gallery will have the groups removed, so there’s a lot of cleanup to do. The code provided below should auto-correct this issue.

Adobe Updater’s Stupidity

I was updating Adobe Reader on a non-profit organization’s laptop and I found this gem: Adobe Updater tries to update it’s Adobe Reader software and complains that it cannot update because its own installer is holding necessary files hostage. Take a look:
