Steam wrappers were introduced in Drupal 7 and allow user file locations to be kept in a maintainable way, although I often forget which function to use to translate them. The three wrappers available are public://, private://, and temporary://, which map to the public, private, and temporary files directories respectively. All user files in Drupal are stored in either of these directories and they are referenced in the database as the file wrapper followed by the location of the file.
It’s been a whole year since the last DrupalCampNW2012 and this years DrupalCampNW (appropriately titled DrupalCampNW2013) seems to have been a great success. This years camp was held in Manchester at The Studio and I was part of the committee of people who helped organise and run the event.
Over the course of the weekend there was a range of talented speakers covering differing issues around Drupal, open source technologies and user experience. The weekend consisted of a Friday business event, followed by a developer and site builder event on the Saturday and Sunday.
My main task during the event was making sure the volunteers we had there on the day knew what they were doing and when to do it. The trouble with organising and running a conference is that you are lucky if you get to see many of the sessions. I did, however, manage to see several sessions over the course of the weekend.
PHPNW13 is the 6th annual PHPNW conference, organised by members of the PHPNW community and Magma Digital. This year the conference saw around 420 people (with myself as a helper) at the conference, which was held in the Manchester Conference Centre.
My involvement in PHPNW13 started a few months before the actual conference. When the call for papers closed back in June I spent a weekend reading the submissions so that we could pick which sessions would be at the conference. Out of the 183 papers submitted (20 more than last year) we had to pick just 35 or so sessions that would be presented at the weekend. The final selection of talks was really good and judging by the comments and rating on joind.in they were well received by the other conference attended as well.
The Monty Hall problem is a counter intuitive problem in probability mathematics that deals with picking the right prize from a set of three doors. The problem is named after the television celebrity Monty Hall and is loosely based on the USA game show Let's Make a Deal.
The WYSIWYG module in Drupal is a great way of integrating a client side HTML editor (better known as a WYSIWYG editor) into a Drupal site. It supports a variety of different editors, all of which can be configured depending on the input format being used by the user. The ability to incorporate many different content editors into a site using a single module means that the configuration interface for them all is pretty much the same. It also means that it isn't a disaster if a different editor is needed for an existing site.
Running complex tasks in Phing can mean running out of memory, especially when altering or changing lots of files. I was recently working on a image sorting Phing project that sorted images based on EXIF information. The many thousands of files involved, along with the custom target used to extract the EXIF data caused the default available memory to run out quite quickly.
Context is a Drupal module that allows you to set up reactions that fire when certain conditions are met. This might be when a certain path is loaded, or when a particular content type page is viewed, or even on every page on a site. When the conditions are met a number of reactions can be fired, which include placing blocks, setting breadcrumbs, or just adding a class to the page template.
When you first install a Munin node it will try to install as many plugins as it can so that it can report on different things. For example, if you have a Varnish server running then Munin will detect this and enable the plugins so that it can report on the activity of Varnish. Once you have started getting data through to your Munin server then you can turn on plugins on the nodes to get more data.
