Good work, nicely explained

My friend Rose Goslinga has been working to create affordable insurance for African farmers. This is not only exceedingly good and valuable work, but I’ve just discovered this Poptech talk she gave about it a couple of years ago.

I think it’s quite brilliant, because, while I haven’t heard her give a talk before, I remember Rose as a quiet, humble lass who I wouldn’t have considered a likely natural public speaker. But I can think of few if any talks I’ve ever seen which convey their message so simply and effectively in under five minutes. If you don’t watch it because you’re interested in how technology can help the poor, watch it as a lesson in public speaking done right.

Going back to my roots?

Recently, I’ve adopted the somewhat complicated habit of having several jobs at once. It’s not always the most productive way to work, but it keeps me on my toes, and life is never dull! And so, today, I started a new job, as a Research Associate in the Cambridge University’s Computer Lab.

Now, this is only one day a week, and it’s a fairly junior post, but it has significance for me, for several reasons. One is that it’s with an old friend, Frank Stajano, helping on what should be an interesting project. A second is that it’s nice to have at least a modest foothold back in academia, doing stuff that isn’t primarily profit-motivated. But thirdly, I’m enjoying a bit of nostalgia.

You see, I’ve been here before.

Just before I started my PhD, I also had an R.A. post in the Computer Lab. And many great people from that time are still around. So in some senses it feels familiar.

I have a shiny new Linux machine on my desk. Well, I had a Linux machine back then, too, but it was rather different. I had commandeered a spare PC and installed this newfangled operating system on its hard disk. I’d experimented before with booting Linux up from floppies, but to have a machine which I could, at least temporarily, dedicate to this skunkworks experiment was wonderful, and it had a decent CPU with enough RAM and disk space that I could run a graphical interface on it! I think I’m probably the first person in the lab to have used Linux with X Windows, which seems remarkable now, when it’s on the majority of desks in the department.

Other things have also changed, not least the building in which the lab is located. The phones on the desks are connected by ethernet cables, not by phone wiring, but of course, I’ll scarcely use it because I now have a phone in my pocket as well. Wow.

But the other thing that really makes me feel old is that the last time I started a similar job to the one I started today, in the same organisation, not one of us had ever heard of the World Wide Web, for the simple reason that it didn’t yet exist.

Gosh, I’m ancient…!

Thought for the day

Economically, there are two kinds of people/households in this world:

  • Those who pay more taxes than they consume.
  • Those who consume more taxes than they pay.

It’s a fairly arbitrary line to draw, and I wouldn’t want to make any value judgments based on it. It’s tempting to call them ‘wealth-generators’ and ‘wealth-consumers’, for example, but that’s too simple. Most teachers fall into the second group, but without them, we’d have fewer people able to be in the first group.

Those in the first group are typically creating value by selling products or services that people want directly. Many of those in the second are doing the same thing, but we buy their products and services via a distributor known as ‘government’. That, to a large extent, is what taxes are.

But I just thought it was an interesting thought experiment, if nothing more. What’s your family budget deficit? How much are you dependent on government subsidy?

And if you don’t like the answer, comfort yourself with the thought that, thankfully, not everything revolves around taxation! How does your balance sheet look in other areas?

  • Those who generate more happiness than they consume.
  • Those who consume more happiness than they generate.

That’s much more important.

Stylish stylesheets

It’s somewhat ironic that, just as we get truly widespread SVG support in browsers – people are starting to create amazing graphics using CSS alone.

For those unfamiliar with the jargon, CSS stands for Cascading Stylesheets – they’re the things that tell your browser the background colour of a page, how widely spaced the lines in this paragraph are, and so forth. SVG is Scalable Vector Graphics, a system for telling the browser how to draw pictures, using components like lines, circles, etc. (as opposed to just embedding a JPEG-type image). SVG is particularly important as displays become bigger, smaller, and higher resolution, because the browser can draw things at the right resolution for even the newest retina MacBook Pro. It’s been around for a long time but has been held back by, of course, poor support in Internet Explorer. However, it’s now more widely supported than Flash, so if you can’t see this little doodle, you really need to find yourself another browser:

I scribbled this quickly in Inkscape, but here’s the beta version of a nice in-browser SVG editor.

But when it comes to artistic creativity, constraints are often a good thing, which is why some of the best photos are taken with prime lenses rather than zooms. And as CSS itself has become ever-more capable, it has allowed people like John Galatini to create this Tube map entirely from HTML and CSS.

You can tell it’s not an image, because you can copy and paste the text.

Just as amazing is Burak Can’s CSS-only MacBook Air, where the screen background is the only image used.

On the other hand, people have been doing some cool but much simpler stuff with CSS for many years. I like Román Cortés’s Homer Simpson from 5 years ago; click the Animate buttons to see how it’s made.

No entry?

No entry to vehicals

Well, that’s fine, because I haven’t got one of those…

Sporadicity

I don’t normally think of myself as a terribly geeky geek, but the postman just called, and we now own the first series of Star Trek.

Actually, the first three series.

On Blu-Ray.

So I guess geekiness must come in bursts…

Lovely Livres

Here’s a quick plug: my next door neighbour, Edel, creates beautiful handmade books. They range from tiny ones you can carry anywhere, to medium-sized notebooks which will make your friends’ Moleskines look very dull, to A4 leather-bound guest books which would be a great wedding present.

As you can imagine, they’re not cheap, but they’re beautiful, they can be personalised in various ways, and you know you’ll be giving a unique gift made with great care by someone who loves her craft. Worth checking out.

From the divine to the ridiculous?

I’m enjoying Remembrance of Things Past, but my expectation of completing the whole thing has been somewhat reduced by my calculating that it’s more than one-and-a-half times the length of the Bible.

Fortunately, Marcel Proust is a much better writer than God, but I fear that may not be sufficient…

Digital Desk Revisited

Thanks to Richard Watts and Rob Hague for pointing me at Fujitsu’s system for interacting with paper using finger gestures.

It’s remarkably like the original DigitalDesk system created by my pal Pierre Wellner in 1991.

It’s funny to think, now, that when Pierre made this video, there was no web to post it on.

At Baggy Point, near Croyde, Devon

Accentuate the negative

On the way home from Devon, to avoid a nasty M4 traffic build-up near Swindon, we stopped off at Lacock, a small Wiltshire village owned almost entirely (and beautifully preserved) by the National Trust.

Lacock, Wiltshire

On the sunny afternoon after a bank holiday, it was a very peaceful spot, and a delightful antidote to the M4. (Or to Swindon).

Lacock is used as a location for many films – we recognised several bits of Meryton from the BBC’s Pride and Prejudice, for example. But it also has an important place in photographic history, because a window at Lacock Abbey was the image Henry Fox Talbot captured in the first known photographic negative.

As we drove home, I couldn’t help wondering what Henry F T would have made of Glenn Morse’s very cool project to build a photographic enlarger. This is no ordinary enlarger, though – the negatives are their own light source, because they’re displayed on his iPad screen.

Pavlovian Titillation

One of the reasons I am sometimes envious of design/media companies is that they can get away with names that, in other sectors, would cause people at least to snigger, if not positively guffaw.

Can you imagine a law firm, or a steel manufacturing plant, deciding to name itself The Marmalade? Even in the technology world that I tend to inhabit, where many companies, let’s face it, have some pretty silly names, I’m still impressed.

But you can get away with such names if you have other ways to make people take you seriously. And Seb Wills pointed me at this Fast Company post which suggests that The Marmalade may not find that too hard. The embedded video clip, showcasing some of their work, contains some very impressive sequences.
