I wrote last time about the latest developments to my Views Auto-Refresh module, which periodically refreshes a Views page, either by reloading the whole view, or by incrementally inserting new items only. It's a useful tool for activity streams and other Twitter-like, real-time lists.
Still, I had a nagging feeling that my code was endangering the server. Consider this: every 15 seconds, each connected browser invokes a full Drupal bootstrap plus a full View render, just to ask the server if there are new items.
Imagine you are creating an activity stream for your site. You'd like to use Views because it gives you all the power you need to query items and style them on the page - all in time for your 11am nap. However, the resulting page is static and users have to keep refreshing it manually to see updates. In 2011, that's just uncool.
That's why I created Views Auto-Refresh, a Views Hacks sub-module that implements an auto-refreshing mechanism that integrates right into Views 2 or 3.
I've been a lazy adopter of Drupal 7. I admit it, mea culpa, but I'll leave this discussion to another post. What happened in the mean time is that VBO for D7 languished for a year or so in a zombie state until it was rescued in early May by Bojan Živanović, bojanz on d.o. He started out by announcing a sandbox project containing his code, and a few days later, I was convinced that this was the way to go for VBO on D7.
I wanted to create a node view containing both the original node and its translation, sort of like this neat Meedan.net page.
As a Web developer, I spend most of my time rendering lists of objects to HTML, formatted in every imaginable way. Fortunately for us Drupal heads, the Views module exists just to make this task easier - this is in fact my standard introduction to my "Views for hackers" talk.
One common scenario that I've encountered, and about which I was asked several times, is how to reuse Views to render a pre-defined list of objects - i.e., a list that already exists without the need for an SQL query. Why would anyone want to use Views in that case?
I gave my "Views for hackers" talk at DrupalCon Chicago yesterday. This was definitely the biggest attendance I've ever had in my short experience as a speaker! Thanks everyone for attending and for the great questions. Please rate it at the DrupalCon site, this will help me improve it.
One of my tenacious ideas is to create a TV-like experience using Web video. In spite of great players such as Boxee, I still feel there's more that can be done.
Secondly, the player should present a simple UI that allows the viewer to surf the enormous amount of existing Web video with minimal interaction. The UI should favour discovery over explicit search.
Taxonomy is a very powerful classification system, so powerful in fact that it's hard (and resource intensive) to fully utilize it in Views and other queries.
