Explanation: On this week’s episode of the Ubuntu UK Podcast we joked about the idea of a Jono Bacon sound board that just says “community”.  I was bored while waiting for a phone call so I made it.  Hope you like it!

That was the OggCamp that was

Last weekend was the 4th OggCamp – a free culture unconference organised by Linux Outlaws and the Ubuntu UK Podcast, along with some co-conspirators.

I’ve been to every OggCamp so far, but this was only my second as an organiser, in charge of the schedule.  That sounds like an easy job as an unconference is traditionally unscheduled, but we like to have 1 track of scheduled speakers so people know what they’re getting.  We managed to book some great speakers this year including Alan O’Donohoe, Simon Phipps (making this his third year as a speaker) and a special video message from Stephen Fry, to name but a few.  Alongside this we had a record 3 unconference tracks packed with talks, all managed by CampFireManager courtesy of Jon Spriggs and his team. In case that’s not enough, we also had hardware hacking at the Open Hardware Jam!

The venue this year was the Art and Design Academy at Liverpool John Moores University.  The building itself was huge, with great facilities and some fantastic spaces.  We had a few issues with locations on the first day, but you never really know how a space will work until there’s people in it.

All in all, the event blew me away.  So many people said so many lovely things about the venue, the community and the event as a whole, I’ll just let you read for yourself.  I’ll just say this: When we organise OggCamp, we have no way to know if anyone will show up or if people will offer talks. It’s a pretty scary proposition. With the community that’s formed around the event, I don’t know what I ever worried about.

The following people deserve my (and your) thanks:
Laura, Fab, Popey, Les and especially Dan, for putting the time and ball ache in to make the event happen.
Jon “The Nice Guy” Spriggs for sitting up coding well past my bedtime.
Andy Piper for stepping in to the breach when we were down a speaker.
The incredible OggCamp crew, who work like trojans for a free mug and t-shirt, and always seem to know what’s going on even when I don’t. You guys rock my world.
Our sponsors: LJMU, Bytemark, Transitiv Technologies, Canonical, O’Reilly and ScraperWiki, who the event happen. Buy their stuff.

See you next year?

Converting Drupal 6 to WordPress

I’ve just moved my blog from Drupal 6 to WordPress. There’s several reasons for this:

  • I was only using Drupal in the first place to get some experience using it. It’s a great CMS but is overkill for just running a blog.
  • WordPress comes with Akismet for reducing comment spam out-of-the-box.
  • I just got a Nexus 7, and there’s a nice WordPress app for Android.

I wasn’t, however, keen on losing my old posts and comments. No problem, Drupal and WordPress are both open source and widely used, there’ll be tools to convert between them, right? Actually, not so much.

The best thing I found was this post on Migrating Drupal to WordPress and the associated Java script (that’s a script, written in Java, not a JavaScript file).  I had to tweak the code a bit to get it working, I’ve put the resulting code on Github.

I’m not really a Java guy, so getting it to run was new for me. Here’s the steps I took (on Ubuntu 12.04):

  1. Dumped the databases for my existing Drupal and a clean WordPress install from my web server to SQL files on my local machine.
  2. Imported both files into a new database on my local machine.
  3. Downloaded the .java file
  4. Edited the database credentials in the .java file to match those on my local machine (wpPrefix variable, drPrefix variable and return line of getConnection method)
  5. Installed the dependencies required to compile and run the file
    ~/$: sudo apt-get install openjdk-6-jdk libmysql-java
  6. Compiled and ran the file
    ~/$: javac -cp .
    ~/$: java -cp .:/usr/share/java/mysql.jar DrupalToWordpress
  7. Exported the resulting WordPress tables from the local database, and imported them back into the database on my web server

A bit of a palava I think you’ll agree, but as you can see, it worked!


A little under a year ago, I mentioned on the Ubuntu UK Podcast that I had contributed money to a project on PledgeMusic. If you’re not familiar with PledgeMusic, it’s basically Kickstarter for music projects. The project in question was Ginger Wildheart’s “Triple Album Project” – If enough people pledged money, he would record 30 tracks. Everyone who pledged would get the tracks, and the chance to vote on the top 12 tracks, which would be released to the world as a single-disc album.

The result of the project is this:
UK Midweek album chart with 100% at Number 9
This is the UK Midweek Album Chart as it stands at the time of posting. The entry at Number 9 is “100%“, the single-disc album chosen by vote from the 30 tracks on “555%”, the triple album which was exclusively available to pledgers (I pledged extra for a physical copy – it’s also got the coolest packaging I’ve ever seen for a CD album).

The album’s entered straight into the top 10, among the likes of Justin Bieber, Cheryl Cole and Rhianna – all A-list celebrities with big record deals who are all over the mainstream media. This isn’t even a down to a big group of die-hard fans going out and buying the album – they already got a copy and more for pledging. This has happened through grassroots promotion, reviews, airplay, and word-of-mouth. No record company involved. I think that’s pretty amazing.

Ginger’s managed to pull this off because he’s got a big group of very loyal fans who trust him that whatever he records, they’ll want to hear it. He’s also a fantastic songwriter who knows a lot of talented people in the music industry, all of which makes this a really special album. It’s questionable as to whether the model would work on this scale with artists who don’t already have established fanbases, but even so, I think this is a major achievement.

Toggle XDebug Bookmarklet

If you code PHP, you probably use XDebug for debugging your code. Some IDEs deal with the gubbins required for starting and stopping the debugger for you, but other debugging clients (like DBGp Client for Vim) require you to manually append XDEBUG_SESSION_START=1 to the end of your page’s query string before you try to connect the debugger.

Inspired by this blog post, I wrote a bookmarklet to toggle XDebug on or off at the click of a button, by adding XDEBUG_SESSION_START=1 if it’s not already in the URL, or toggling between XDEBUG_SESSION_START=1 and XDEBUG_SESSION_STOP=1 if it is.

To add it to your browser, drag the following link to your Bookmarks toolbar
Toggle XDebug

The un-minified code is shown below:

javascript: (function() {
    var href=window.location.href;
    if (href.indexOf("XDEBUG_SESSION_START") != -1) {
        window.location.href = href.replace("START", "STOP")
    } else if (href.indexOf("XDEBUG_SESSION_STOP") != -1) {
        window.location.href = href.replace("STOP", 'START")
    } else {
        if (href.indexOf("?") != -1) {
           window.location.href = href+"&XDEBUG_SESSION_START=1"
        } else {
         window.location.href = href+"?XDEBUG_SESSION_START=1"

Installing CyanogenMod on HTC Legend

For various reasons, I decided that it was time to do away with the stock firmware on my HTC Legend and install CyanogenMod.
The CyanogenMod wiki details the process for rooting the phone, installing a custom recovery image, an installing CM, but I found the following process much simpler:

NB: You will need a Windows PC.

  • Sign up for an account at and log in
  • Select “HTC Legend*” from the –Select your device– menu
  • Follow the process to unlock your bootloader – As the warnings say, this may void your warranty, and attract extra repair costs if your phone breaks.
  • When complete, download the custom recovery image
  • Place the image in C:\Android and rename it to recovery.img
  • Install the custom recovery image with the command fastboot flash recovery recovery.img. You can now boot into Recovery by selecting “RECOVERY” from the bootloader menu.
  • Install CyanogenMod using the Method via Recovery

Apparrently some phones have issues with this method as the kernel needs to be flashed seperately from CM, but I didn’t find this necessary with the Legend.

Update 12/1/13: There’s a developer on the XDA-Developers forum who’s creating unoffical ports of newer CyanogenMod releases based on Android 4.x. I’ve just installed his CM 10 ROM using the same method as 7 and it runs great.

Setting up CoffeeScript on ubuntu

As I mentioned in a previous post, I recent learnt about CoffeeScript, a quick way of writing nice clean Javascript. The CoffeeScript website has instructions for installing the compiler, first requiring installation of Node.js, which a lot of tutorials show you how to install from Git, and also requiring NPM which is usually installed by curling a shell script directly into bash(!). On Ubuntu, the install process is much simpler and less ripe for security holes:

  1. Only required if running 10.04 LTS (Lucid Lynx):
    sudo add-apt-repository ppa:chris-lea/node.js
    sudo apt-get update
  2. sudo apt-get install nodejs npm
    sudo npm install -g coffeescript

Check that CoffeeScript is installed correctly by running

coffee -v

What I learnt at Dev8D 2012 – Day 3

Day 3

I decided that I’d spend the final day trying to write some code, so I began trying to implement the Google Docs Viewer idea from Day 1.

I started off trying to write a Moodle Filter plugin to change file download links into iframes. However it quickly became apparent that the link I wanted to change wasn’t actually processed by the filter, so I had to try something else.

I moved on to modifying the Moodle File Resource plugin – it currently attempts to embed PDF files if it can, so I used that as a starting point. However due to the previous 2 days of information being stuffed in my head, I didn’t do things in any logical order and ended up in a bit of a mess. I really need to start again with the following approach:
* Create a new table in Moodle’s database to hold single-use tokens against a file’s path
* Create a copy of Moodle’s file.php that allows you to request a file without logging in, but only if requested with a token that’s stored against that file’s path.
* Get this page working so that Google Docs Viewer can request the test file with the test token and display it.
* Change the code that attempts to embed PDFs to embed any file type supported by Google Docs Reader
* Get the embed code working for the test file with the test token
* Implement code to generate and store a single-use token when the resource page is requested, pass it to Google via the embed code and delete it after the file is requested once. Also implement a cron job to clean up expired tokens if they aren’t used.

I finished off the afternoon by having a chat with Ian Tasker from SchoolsICT (who also sponsored the event), and James and Nigel from ULCC who produce the Moodle ILP plugin. The discussion we had gave me a great insight into what their system is capable of, and I’m looking forward to get to grips with writing some plugins for it myself.

What I learnt at Dev8D 2012 – Day 2

Day 2

The second day of Dev8D started with my Moodle Plugins workshop. It was reasonably well attended and the people who were there seemed to find it useful. I certainly found it an enjoyable experience.

After lunch I attended Jack Franklin’s sessions on CoffeeScript. It’s a really interesting idea, and next time I’ve got some Javascript to write I’ll try writing CoffeeScript instead to see if it really does save me time and effort.

The project zone had a brilliant demo of the “ghetto touch-table” from the University of Southampton – basically a home-made Microsoft Surface-style set-up. The thing that really interested me about it was it’s simplicity – a sheet of Perspex with IR light shining through it, and a camera to pick up light that gets reflected down by an object touching the surface. It only had a few purpose-built apps that could use the touch functionality, but I’d love to see it again once they’ve got it controlling the OS.
