Well here we are again, another year, another LugRadio Live. For anyone who has never heard of it, LUGRadio Live is a community conference for supporters of Free and Open Source software.

Some big changes are taking place this year though, as the date had been altered from July to October, the venue has moved to the Newhampton Arts Centre just outside Wolverhampton, and unfortunately the conference is only for one day. Still, these points aside it remains an excellent event. Here’s a quick summary of what went on, and of the talks I attended:

Brock Craft – tinker.it

Brock is from London-based design-studio tinker.it, he spoke about the open-source hacking platform Arduino. Arduino was designed to be a cheap and easy method for learning about electronics and hardware hacking, and as a quick method for building devices. Brock gave examples of its usage by artists, designers and hobbyists, and it certainly seems like it could have many ingenious uses, including the RFID cat flap which Brock had built for his own feline friend.

Gervase Markham – Mozilla Drumbeat/BBC Basic

Gerv spoke firstly about Mozilla Drumbeat, which is essentially a grass roots campaign to keep the web completely open to all. Gerv mentioned net neutrality, the mobile web, and closed application stores such as the Apple app store as examples of threats to the web. The project’s motto is ‘people, ideas and action for a better internet’ and it’s certainly an admirable aim we should all support! In the spirit of the conference’s ‘back to basics’ theme Gerv then presented his first ever program, written at age 8, a ‘choose your own’ adventure style game written on a BBC Micro. Gerv is a charismatic and engaging speaker, and the presentation raised a few good chuckles from the crowd.

Matthew Somerville – MySociety

Matthew works for MySociety, a registered charity probably best known for their work with the Number 10 petitions website. Matthew spoke about the various projects they have undertaken over the past few years. These include TheyWorkForYou, which can alert users when their MP speaks in Parliament, and holds transcripts of Hansard from 1935 onwards. It has also recently started hosting videos of parliamentary proceedings. Closely related to this is WriteToThem, which allows anyone to contact their MP directly, and HearFromYourMP, which is essentially the opposite.

Matthew also spoke about some projects which are designed to make life easier for people and communities, for example FixMyStreet which allows members of the public to report problems such as potholes and graffiti to their local council quickly and efficiently. MySociety has produced some excellent and easy to use services and hopefully this will continue.

Des Burley – A Real Lawyer Speaks

Des works for the independent law firm Martineau, and came to speak about trademarks and licensing in free/open source software. He covered the reasons why people would want to trademark software, what can be covered/protected and the differences between trademarks and copyright. He also spoke about the harm that can be wreaked by patent holders, with the model railway software designed by Jacobsen being a good example.

Andy Robinson – OpenStreetMap

OpenStreetMap is a project designed to provide everyone with a complete, open and free mapping facility. I already had a little background info on OpenStreetMap from a talk given at Manchester Free software last year, but it was really interesting to see how far the project has come since it’s conception, and that we might soon reach a point where the information stored in the OSM database is of better quality than that of any mapping company. Andy also gave the interesting example of the work done in OSM to build the first complete and accurate map of the Gaza Strip, which was then being used in the humanitarian relief effort during the Gaza war in January this year.

Steve Lamb – The Changing Face of Work

Steve Works for Microsoft, but don’t let that put you off, honest! Steve has been at loads of the LRL events and always puts forward an excellent talk to present to us freedom-lovers. Steve spoke about giving employees more freedom and flexibility in their use of technology, whilst somehow creating a balance between work and home technology. He quite rightly suggested that it can be counter-productive if an employer forces specific tools or devices onto employees, and there were many excellent points to agree with.

Summary

The Twitterfall

The Twitterfall

The event was well organised this year, with the main stage featuring three big screens. One featured the presentation slides as they were delivered. One was used by an excellent portrait artist who sketched each speaker as they were on stage using the Gimp and a drawing tablet. The final screen featured a live twitter feed (or ‘twitterfall’), to which any conference attendee could tweet using the #lrl2009 hashtag, all tagged messages then appeared live on-screen. This produced some hilarious moments during and in-between talks, as ASCII drawings and abuse were consistently twittered by the delegates throughout the day. The conference music was excellent as always, with Rage Against the Machine, Paramore, Bowling for Soup, System of a Down and the Offspring all featuring prominently!

During the recording of the live show, the presenters announced that this really was the last LugRadio event, although it was later discussed that if someone else were to arrange the event next year, then the LugRadio presenters agreed to attend to provide another dose of their unique presenting style. So hopefully this won’t be the last we hear from the LugRadio crowd and I’ll be back in Wolverhampton next year!

OggCamp

UbuntuUK & LinuxOutlaws

With LugRadio Live having been cut down to just one day this year, it was obvious that someone would come along to fill the void. OggCamp is an ‘unconference’ (ie: an unorganised conference) where rooms are set aside and anyone can turn up and offer to speak on any free/open source related subject.

The event was held in the Connaught Hotel, around 10 minutes walk from the centre of Wolverhampton. The schedule of talks for the three rooms quickly filled up, and I attended a few fantastic presentations. I attended Tim Dobson’s presentation on his DFEY group, and Bruno Bord’s talk entitled ‘Explaining programming to my grandmother’. Although my favourite was presented by Andy Stanford-Clark with his talk on his ‘Twittering House‘ (as featured on the BBC) which tweets such events as power consumption, windows/doors opening, light/appliances being turned on/off, phones ringing, as well as other useful information about the house.

His most recent addition being an SMS controlled Rudolph light display on his roof. This tied in with other cool little projects Andy had been working on, such as monitoring his local ferry using the ship’s radio frequencies which were then fed into Twitter, and eventually adopted by the ferry company as their live ferry update service, it was very entertaining to see how much could be achieved on such a small budget.

OggCamp certainly filled the void left behind the second day of LugRadio, and hopefully OggCamp will continue even if a LRL event can’t be arranged for next year. All in all, an excellent weekend, I met some nice new people, put some faces to names, and caught up with old friends. Roll on next year, in whatever form it takes!

Ubuntu 8.10

Category: Advocacy, Free Software, Geek StuffJonathan @ 7:25 pm

As usual I like to write a brief review of the latest Ubuntu versions as they are released, or in my case when they hit the release candidate stage, as I hate trying to use the overcrowded repositories on release day.

8.10 isn’t a massive release by any measure, there are only several noticeable improvements, although it seems that a lot of time and effort has gone into making this release as stable as possible. For me, even though 8.04 was a LTS (Long Term Support) release, it seemed to lack the stability that I had come to love in Ubuntu, applications would crash for no reason, and I had massive conflicts with Flash9, Firefox and Amarok all trying to hog the sound output, with no end of frustration caused.

Ubuntu 8.10 Desktop

8.10 is a fantastic return to form for the Ubuntu team, the addition of Flash10 (despite it’s proprietary evilness) is a welcome upgrade as it solves a lot of the issues that dogged my daily web browsing sessions. Network manager has had some major improvements, now supporting VPN, Wireless, DSL, and mobile 3G broadband services, through a nice (although sometimes confusing) screen.

There’s the usual updates to X.Org, the kernel and Nautilus, the latter now providing a nice tabbed browsing interface, probably not something I’ll use, but I’m sure some people will see great uses for this. Nautilus is also now more tightly integrated with Pidgin, meaning things like status messages can be updated through the Gnome panel, a nice little addition. Another upgrade to File Roller means that it supports many more compressed archive types, which saves wasting time installing different archiving applications.

We also have the addition of an optional encrypted private directory, meaning your sensitive files can now be stored and encrypted very easily, although with the advent of the 2000 Regulation of Investigatory Powers Act, which forces citizens to hand over their encryption keys/passwords if requested by the authorities, this facility may have lost a lot of it’s advantage for some users.

Another nice little feature is the built-in guest account, something I have previously had to create myself, which allows you to quickly launch a low privilege password-less account, with absolutely no access to the file-system, in case your mate needs to quickly check his or her email on your laptop.

All in all I have found 8.10 to be rock-solid so far, and really wish that 8.04 LTS had offered this same high level of stability!

Data Recovery with Free Software

Category: Advocacy, Free Software, GNU/Linux, IT, UncategorizedJonathan @ 11:16 pm

Prompted by various people accidentally losing their digital camera images/videos and other people deleting things from USB keys etc I have been doing some research into data recovery software over the past few weeks.

It comes as a surprise to many people that ‘deleted’ computer files are not in fact deleted at all by default, the space on the disk that they occupy is merely reallocated as blank space, to be written over as and when it is required, meaning that deleted files stand a relatively good chance of being recovered depending on how much the disk has been used since. Whilst there are many commercial photo recovery packages available, I wanted to avoid having to steer people down this expensive and not necessarily reliable path.

Free Software provides an interesting contrast to this, with the excellent PhotoRec, part of TestDisk. The Ubuntu community wiki lists several other applications for data recovery, but these aren’t all cross-platform, wheras TestDisk/PhotoRec will build and run on just about anything. Whilst it does lack the bells and whistles of the commercial packages (and it really is screaming out for a basic GUI front end to tempt people towards Free Software, and if I could write one I would!) is nevertheless is a simple and very reliable package for Photo, Video, Document and almost any other file type of data recovery.

Available for Linux/OSX/BSD/Solaris and even MS Windows, PhotoRec can recover more than 180 different file types across all of the major file systems (FAT, FAT32, NTFS, EXT2, EXT3 etc) and on just about every type of camera or removable media device there is.

Despite my complaints about the lack of a basic GUI to assist the less-technical users, the command line interface is almost foolproof, everything is auto-detected, and given the completely read-only interface of the application it’s fairly impossible to cause any damage.

Pre-built packages are available for almost every GNU/Linux distro, and a simple “sudo apt-get install testdisk” within Ubuntu will have you ready to roll in 30 seconds flat.

The screen shots below show an illustration of a data recovery being performed on a 1GB SD card.

Overall I have found PhotoRec to be one of the best-written GNU/Linux tools I have ever used, it does it’s job extremely well, is very easy to use, and is a perfect example of just how good Free Software can be. I’d advise you to bookmark the web address and grab a copy next time you or someone you know accidentally deletes something!

Richard Stallman

Category: Advocacy, Free SoftwareJonathan @ 11:05 am

I attended a talk last night by Richard Stallman at Manchester University. Richard is the founder of the GNU Project and the Free Software Foundation and promotes Free Software adoption worldwide. We were also doing some promotion and flyering for Manchester Free Software at the event, the talk having been expertly arranged by Paul Waring.

Richard gave a history of the GNU Project, the four freedoms and Free Software’s benefits and advantages over proprietary software. He also spoke about DRM and the other dangers of non-free software, such as hidden back doors and other spying and monitoring activities.

Richard also covered some of the important reasons why businesses, government and educational establishments should use Free Software, preventing the support and development monopolies which are now becoming commonplace, along with the problem of proprietary vendors offering gratis or near-gratis copies of their software to schools in order to keep students reliant on their package and then carry this reliance forward into their future academic and business careers.

We had only been expecting around 100 people to attend but the 300-seat lecture theatre filled up completely, with latecomers sitting in the aisles, it certainly shows how many people interested in Free Software we have in and around Manchester. The talk was very informative and I hope Richard returns to the UK at some point in the not too distant future.

Brainstorm

Category: Advocacy, Free Software, GNU/Linux, Geek StuffJonathan @ 4:59 pm

For anyone who hasn’t yet seen Ubuntu’s brainstorm website, it is an excellent community driven website where ideas can be suggested on any aspect of Ubuntu development, these are then voted and commented on by visitors to the site with the view that they be implemented in future releases. It’s an excellent website as anyone can participate and hopefully make a difference to the future development of Ubuntu.

My own brainstorm idea is a simple one, but I feel is could be very effective. Whilst watching a documentary on BBC3 it occurred to me how much free advertising Microsoft gets based on their default Windows logo screen saver. During a 1 hour documentary I’d say Microsoft got around 3 to 4 minutes of free advertising during interviews with people sat at their desk’s by their computer screens and I suggested that perhaps a default Ubuntu screen saver might provide some additional advertising.

I suggested the idea on the 31’st of March and it is currently at 135 positive votes. Making it the 3′rd most popular idea in the Marketing category.



If you feel obliged, click above and give it a vote!

Update: I have been notified that a Ubuntu screen saver has been present in the past, but had been missing from the last few releases. I am assured that it will be back in the operating system soon. Job Done!
