Reducing system load for graphical widgets

Submitted by Frederic Marand on Thu, 2008-08-21 22:02

Using a graphics library, be GD, ImageMagick or anything else, is convenient, but carries a price to pay: unlike most Drupal parts, which are generally database-bound, image generation is typically CPU-bound: generating many images on the fly can significantly increase the CPU load on a system, while Drupal setups are typically not optimized for this, and could result in problems if you are using Drupal on a shared hosting account. So what ?

A progress bar widget for FormsAPI

Submitted by Frederic Marand on Sun, 2008-08-17 15:18

Forms API progress barAs a Drupal user, you certainly noticed that update.php displays a nice progress bar to make you wait during its batch operations. And maybe you also noticed theme_progress_bar in the API reference.

The question

Wouldn't it be nice to have that progress bar available as an extended version of markup that would graphically display a value in your forms without stuffing it in a markup element ?

Checkboxes in forms step by step

Submitted by Frederic Marand on Tue, 2008-08-12 22:09

For some reason or another, I've noticed several new Drupal developers these last few days sweating on Forms API, and thought it would be nice to have a smallish example to complement the unavoidable FAPI reference and Guick start guide, for a typical non-basic form: one including set of checkboxes in a table, with a customized display, like the core user, content or modules administration forms. So follow me while we build this example.

Grokking Drupal: module dependencies in e-Commerce 4

Roughly two years ago, I prepared a diagram of the dependencies in the then-current version of Drupal e-Commerce (eC) for Drupal 4.6.

Dependency diagram for Drupal e-Commerce 4 Now, with other eC projects looming ahead, a possible session about eC at Szeged, and eC 4 being in alpha, I figured it was time to update the model. Boy, has it changed ! Click the thumbnail for the full-size view.

e-Commerce sessions in Szeged

Submitted by Frederic Marand on Thu, 2008-07-24 21:05

If you are [considering] working on an e-Commerce site, and are coming to the Szeged Drupalcon, you may be interested in several sessions around the theme. In order for your session(s) of choice to stand a chance of being actually part of the conference program, you should vote for the sessions you would like to attend.

Subjet to approval by the conference board, I will be animating/presenting a session about the internals of the e-Commerce suite: see http://szeged2008.drupalcon.org/program/sessions/developing-e-commerce for more details. If this is of interest to you, vote on the session to make sure it will indeed be included in the conference program.

I've been keeping track of various technical stats for OSInet's sites for as long as they've been existing (and that means well over 10 years, mind you !), and the June figures show a long expected landmark has been reached : for the first time since the creation of these sites, the operating systems declared as being Unix-ish by user agents (browsers) visiting our sites in June 2008 has broken the 10% barrier (10,08% to be accurate).
