Drupal module idea: creating feedback screenshot

Screenshot feedback Google+

If you use Google+ you may have noticed the excellent feedback feature that they offer. You can click on a button and highlight any part of the site. The site will then create a screenshot where you can add a description and send back as feedback. This could be a great usability improvement for bug tracking and providing feedback in any site. Luckily, some clever developer managed to reverse engineer this functionality. It is a javascript library (available at GitHub) which uses the browser and the canvas element to create a screenshot: html2canvas. Drupal module anyone?

Drupal caching explained

Wrote an article last week about Drupal caching. I tried to identify exactly what each setting does on the admin performance settings screen (in Drupal 7). Work in progress (feedback is welcome) but it might be helpfull for people who wonder what those checkboxes and dropdowns exactly do.

Tech Talk 4 recap


The fourth Drupal Tech Talk was held in Rotterdam (@Hoppinger) yesterday, and included talks from Rolf van de Krol about Ctools (especially howto create plugins and make modules exportable via ctools) and Heine Deelstra about Drupal security (best practices and tips). Rolf demonstrated ctools by showing a cool module called "gnome planks" which allows easy control of blocks in contexts without users having to access context admin UI.

Using regular expressions in views fields

XKCD regular expressions

I try to avoid regular expressions whenever I can, but sometimes it's just the easiest/fastest way to get stuff done. For example, I had these ugly RSS aggregated titles which were full of HTML entities and other jibberjabber. They were displayed using Views and the core aggregator. Using Views Field Rewrite I cleaned up the titles with some regexp.

How does caching work in Drupal?


In my experience, there seems to be a lot of misunderstanding how Drupal caching works. I'm not talking about advanced caching mechanisms like Varnish, APC or memcache here, I'm talking about the core Drupal caching: page cache and block cache which are available in Drupal 7 core. Drupal 6 is similar but works a but differently because page caching was simplified for Drupal 7 (e.g. aggresive mode is now a available as a settings.php var) and the entire system also has become pluggable.

SOLR search within a radius distance in Drupal 6/7

Drupal 7 geospatial SOLR search

Great article by Domique de Cooman about howto setup SOLR with Drupal 7 and geospatial search which allows you to search within a distance radius using the location/gmap modules. Some of these modules (search API) are not available for D6, but there is another module available for Drupal 6 and an alternative approach by upgrading SOLR to 3.1.

Frontend United Netherlands 2012

Frontend United Netherlands 2012

Another Drupal event coming up this spring: the Frontend United Netherlands (FUN for short?) was previously known as the Drupal Design Camp and now a yearly conference targeted at Drupal frontend people. Designers and themers unite! The event will be held from 20-22 April in Pakhuis de Zwijger in Amsterdam. Read more about it at the official site.



This looks like an interesting concept which was just launched yesterday: Livethemer, a way to change the layout and style of your site, almost the way you can in a DrupalGardens site. The service requires a module, an account on livethemer.com is optional. According to the site, the team worked for almost 2 years on this project. While I don't believe you should give clients this kind of theming power, and professional themers won't use this either, there might be a niche target group for it. Check out a demo video on vimeo.

Drupal 8 progress

Dries and Sam Boyer creating a Drupal 8 branch

One year after Drupal 7 has been released, Dries announced that version 8 is probably 2 years away. In case you are interested, the best way to track progress is following this group (RSS) and follow the websites/twitter/google+ feeds of the six core initiatives maintainers. Also, don't forget to keep an eye on Dries' tweets/blog and his Drupal 8 co-maintainer 'catch'.
