MyPud

October 14, 2009

It has been some time, so I thought I would restart proceedings for the autumn with a quick link to Cambridge computing lab pioneer Quentin Stafford-Fraser. Here truly is a man after my own heart as in between blogging about 3G femtocells and recursion he’s found time to consider the future of puddings.

He proffers the idea of a social networking site for recipes as a means to further their evolution, although I have to say it’s not the first time I’ve come across this idea. When I first started working at Intelligent Content one of the development projects that (fortunately) never came to fruition was of a similar ilk – although the concept of social networks didn’t exist then, of course. Quentin has form in this area – he was one of the instigators of the Trojan Room coffee pot affair.

Turing’s Last Syllogism

September 11, 2009

It is not often that computer scientists trouble the front pages, but today’s news of an apology by the PM for Alan Turing is long overdue. Much of what we take utterly for granted when sat in front of our PCs can be traced back to his work in the 1940s. The news prompted me to dust down my old copy of David Leavitt’s biography of Turing (“The Man Who Knew Too Much”). In one of his last letters to a friend he tells of his forthcoming prosecution for “sexual offences with a young man” and his disappointment following a lacklustre performance in a BBC radio broadcast. He concludes the letter with: “I’m rather afraid that the following syllogism may be used by some in the future:

Turing believes machines think
Turing lies with men
Therefore machines do not think.”

Googlegrams

June 1, 2009

Friday lunchtime I escaped the shackles of my desk for a rare, UK exhibition of the work of Catalonian artist Joan Fontcuberta at Nottingham’s Djanogly art gallery. According to the curator, Neil Walker, Fontcuberta’s work questions the nature of truth and, in particular, the reliability or otherwise of photographic documentary evidence. The artist’s previous works include a complete portfolio of faked photographs purporting to document a Soviet space mission that went badly wrong in which a cosmonaut was lost in space. However, that’s not the TechLunch link. What interested me was the current display: Googlegrams.

Googlegrams are large photographs (about a metre square) constructed from thousands of small photo ’tiles’ in the style of a mosaic. Each tile consists of a tiny image taken from the Web, sourced from Google’s image search engine. Fontcuberta takes an image from current affairs, for example there is one showing a number of drowned African refugees who have been washed up on a Spanish beach, and replicates it in Google-sourced tiles.

In order to make this work, Fontcuberta has doctored a piece of freeware software, used for what’s called photo mosaic-ing, which selects tiles that correspond to the colour and shading of the large image. The software works out that it needs, say, 80 tiles that overall correspond to a particular shade of light blue and when it finds a tile that fits its requirements it will fill in the image accordingly.

In order to source the tiles, the ‘artist’ has to type in search terms to query Google’s image search engine. In the case of the refugees, Fontcuberta typed in the names of the twenty-five richest men in the world. The images that Google throws up are used by the software to find the right colours and shades to use as tiles.

Walker argued that the artist is setting out to challenge the prevailing view that accurate information is available from the Web. Fontcuberta is sceptical of the idea of a universal, democratic source of truth, exemplified by the work of Wikipedia. The Googlegrams are metaphors for the inherent instability and transient nature of the information and truth on the Web.

The exhibition not only shows various examples of Googlegrams, but there’s also a live demonstration of the software that allows you to construct your own image. The gallery is also right next door to its own eatery – so a bit of tech and a spot of lunch – although I’d advise you to eat before one o’clock as the servery is pretty much stripped bare by then.

The exhibition runs until 14th June, but if you can’t get to Nottingham, the gallery has produced a YouTube video, including an interview with the artist.

Here comes the flood – the curator is as important as the creator

May 15, 2008

He once sang ‘Here comes the flood’ and he now seems to have taken the message to heart. Former Genesis front man Peter Gabriel is working on a project called The Filter which will help people navigate through the ever-expanding ocean of online information and digital assets.

In a world of a bewildering range of choice, Gabriel argues (in a Reuters video clip) that the curator is as important as the creator. What he seems to be arguing is that sharing our collections, playlists etc. of digital content can help us find new, interesting and relevant content.

The Filter tool joins a growing band of personalisation services that help people make sense of the huge choice of music, video, films and other media that is now available online thanks to the Long Tail. These services track your personal preferences, make sense of your online purchases and keep an eye on the stuff that you browse. In the case of the Filter, the ‘engine’ that drives it is a complex algorithm based on a branch of maths called Bayesian statistics. It works out patterns of interest and makes suggestions for related materials. The real power will come when these mathematical pattern profiles can be shared through social networking websites.

A public launch is promised next month, although I hear news that his server was stolen over the recent bank holiday.

Richard Stallman in Manchester

May 6, 2008

Wearing no shoes, with long hair flowing, Richard Stallman sipped a cup of tea while he regaled a packed lecture theatre at the University of Manchester with a tub-thumpingly passionate and eloquently argued case for Free software.

Stallman is the American enfant terrible of the computer software industry. His radical ideas fuelled his breakaway from the pack in the 1980s, when he set up the Free Software Foundation – that’s free in the sense of liberty rather than free of charge. For most people it’s a subtle distinction so I’ll use his own words to explain:

“Free software means software that respects the users’ freedom. Our society encourages people to judge programs in a shallow way based only on practical convenience – how powerful is it, how reliable, what does it cost and to ignore the most important questions: what does this program do to my freedom. What does this program do to the social solidarity of my community? These questions are what the free software movement is all about.”

Unsurprisingly, given Manchester’s history of radicalism (think Anti-Corn Law League and the Peterloo Massacre), Stallman found a natural audience. The crowd loved every minute of his talk, they roared for more, and, afterwards, they literally besieged him to get his signature on books, slips of paper, and even, in one case, a laptop lid. This is as close as it gets to rock ‘n’ roll in computer science.

Once the dust had settled I was able to make my approach. I was there to get a post-show interview for Oxford University’s OSS Watch website, and after several ‘ah-ha’s while I explained who I was, Stallman’s first question was “do you know about my rules…?” I was made to promise that I would be careful during the interview with the use of certain words associated with the free software movement, for example, to always refer to GNU/Linux, not Linux.

With the niceties over, a fascinating, and at times rambunctious, half hour ensued. I did quite well with my vocabulary during the first half of the interview, but the second half was trickier, whether through clumsiness or fatigue on my part, and there were a couple of near misses. However, I have to say, it was worth it.

Stallman is an engagingly unusual character. If you ignore, or even just simply enjoy the eccentricities, you have a man with a powerful message and one that is so rarely heard. It is a compelling case for programmers and users to become much more aware of the democratic and social implications of software.

It hasn’t all been just talk, either. Stallman combines the programmer’s eye for minute detail with sweeping ideas about freedom. By concentrating on the detail – the exact wording of things like software licences – he has driven forward his concept of free software.

I came away impressed by a man who has the courage to challenge other technologists with talk about ethics and values. The sort of stuff one doesn’t hear too much about in these nervous, corporate, globalised days: social solidarity, individual liberty, democracy, community ethos, public service. The way he articulates his message is clear, deeply refreshing and at the same time curiously old fashioned. There were moments during the interview when I imagined this must have been what it was like hearing one of the radical political thinkers of the eighteenth century speak: only with a deep knowledge of modern technology.

In true radical style Stallman completed the interview with a made-up folk ditty about Gordon Brown being a clown and the English always being free (sung to the tune of ‘Rule Britannia’). And for a computer person, his singing voice wasn’t too bad, either.

UPDATE: Feb 2011 – the FSF have now uploaded a video of Stallman’s Manchester talk

So farewell then to the twelve-sided dice

March 10, 2008

I was sadden to hear the news that Gary Gygax, co-inventor of the Dungeons and Dragons role-playing game, has died. I confess that, like many computer scientists of my generation, I was an active player in my youth and I had one of the first copies of the UK version of the game. Although 1970s Britain may have been a grey and grim place of mass unemployment and stagflation, the game easily transported me to a magical land of dragons, trolls, swords, sorcery and heroes.

These games involved nothing more sophisticated than a group of people, lots of pens, graph paper, bags of imagination and of course the famous multi-sided dice collection. Computer scientists tend to have a reputation of being rather anti-social types who like to hide in cupboards but role-playing games could be intensely social and I’ve been involved in truly raucous games with a dozen or more players.

As far as I can tell D+D (as it was known) is the basis of the vast majority of modern computer games. I was interested to read in Gary’s obituary in the Guardian that although he accepted that computer games were inevitable he wasn’t that enamoured with them, preferring the sociability of the original role playing game. He is quoted as saying: “Your imagination is not there the same way it is when you’re actually together with a group of people”.

John Backus

April 20, 2007

It’s not often that a computer scientist makes the obituary column of national newspapers. So it’s interesting that the death of John Backus, the inventor of the Fortran programming language, made it into the Guardian and New York Times recently.

Anyone who is old enough to remember struggling through scientific programming classes using Fortran 77, will perhaps recall cursing the inventor of a language more orientated to the days of the punch card. However, Backus should be remembered for introducing the basic concept that machines could be programmed using English-like notation rather than an impenetrable stream of numeric codes (as was the case at the time in the early 1950s). The first version of the Formula translation (Fortran) language appeared in 1957 and the British Computer Society recently celebrated its jubilee. It’s still going strong, indeed work is under way on Fortran 2008.

Backus’s work led onto a plethora of other high-level languages such as Pascal and Java. This brings to mind the infamous real programmers don’t use Pascal letter which first appeared in Datamation magazine in 1983. This was a tongue in cheek computer science version of the ‘real men don’t eat quiche’ phenomenon. In a time when there was a concern amongst some that computer languages were becoming a bit, well, easy, this was a hacker’s attempt to separate the wheat from the chaff. It included lines like: ‘Real Programmers aren’t afraid to use GOTOs’ and ‘Real Programmers don’t need comments– the code is obvious’.

The letter also contains the immortal line:
‘Real programmers arrive at work [just] in time for lunch’.

Tom Loosemore on JISC

March 15, 2007

Just one more thing on the JISC conference. The closing plenary session was given by Tom Loosemore, Head of Broadband & Emerging Platforms at the BBC. He opened his talk by explaining that back in the late 1980s, when he was supposed to be studying for his degree, he was actually spending most of his time exploring and experimenting with his university’s Internet connection.

I should perhaps explain that ‘back in the old days’ the only people who had access to the Internet were university staff and researchers. This was partly because the universities had had the foresight to install their own high-speed network (called JANET). Tom’s point was that this pioneering spirit had provided people like him with the opportunity to experiment with the latest thing years before it took off and became popular. He gave a big thank you to JISC for having the vision and taking the risks, and said, “this country would be in a worse place, both culturally and economically, if it wasn’t for you.”

What’s interesting about this is that people of my generation owe a huge debt of thanks to the Beeb. Not for their radio or telly broadcasting (although Blake’s Seven was rather good) but for the introduction of the BBC micro computer. I sincerely believe we wouldn’t have such a vibrant and creative software industry in the UK if it wasn’t for the generation of software programmers, e-learning and games designers raised and bottle-fed on the BBC micro in the 1980s.

Hogarth

February 21, 2007

To London and a visit to the Tate Britain for the wonderful William Hogarth exhibition. I can’t rate this highly enough: a lost world of harlots, rakes, gambling aristocrats and corrupt politicians is brought to life. The depth of characterisation in each of his pictures and the many layers of storytelling taking place is breathtaking. Satirist, artist and engraver: who can fault a man who comes up with characters such as Moll Hackabout and the Rape Master General and often sets his scenes in the mythical town of Guzzledown. His work was, in his own words, partly a moral crusade to establish ‘modern’, urban life – including lowlife – as an appropriate subject for art. This left me wondering, where are today’s Hogarths – satirising our modern life through great works of art?
