Brainy precautions

SpocksBrainThe aliens want to steal your brain… I think that’s fairly well established by now, but how to recognise them is less certain. Douglas Adam fans would assert that it’s the white mice you should be fearful of, while the followers of Roddenberry are more concerned about the delicious young ladies of Sigma Draconis VI.

In either case, it’s best to be prepared for all eventualities, and what better way than to have a spare brain you can hand over when requested? With a bit of luck, the aliens will be content with that, and leave you to boldly go about your other business.

My friend Richard has already got his. Here’s how he did it.

Virtual interior decorating

My Photoshop skills are a bit rusty, but I revived them over the weekend for a quick job on behalf of Rose’s college. They have been contemplating the possible hanging of a large painting in a couple of new locations, and wanted to get a feel for how it might appear.

The painting, however, is over 2m square and currently in storage, so just holding it up for a moment while someone else gives their opinion would have been a little impractical. So I offered to do a quick non-artist’s impression.

Isn’t technology wonderful?

Moving with the times?

I’ve spent the last couple of days in Winchester, helping my brother & his family move house. All went well in the end, but we really need to fix the archaic English system of money transfers that happen on the day.

For those unfamiliar with the process, it usually involves the first solicitor in the chain pressing a button on some system which transfers the purchaser’s money to the vendor’s account, and unless there are cash buyers in the chain of purchases, this proceeds from solicitor to solicitor during the course of the day. When confirmation of each transfer is received, the estate agent hands over the keys.

In our case, five family members plus two removal men and a very large truck were waiting outside the house for a couple of hours until one solicitor came back from lunch, only then to discover that another solicitor had pressed the wrong button at 8.45 that morning so nothing had transferred. But nobody had informed anyone…

A similar confusion then happened later in the day to our vendors when they arrived at their new house… they had the keys, their belongings were being unloaded onto the front lawn, and the estate agent then screeched up in the car and tried to take the keys back because someone had misread the confirmation about their transfer and it hadn’t actually gone through.

I suspect other countries have this sorted out in a much better way which takes the unreliable lawyers out of the loop. Not least Scotland. They’re canny that way…

Sports hound

Had fun with some high-speed shots of Tilly chasing her ball on the college hockey pitch this morning.

Tilly still had energy left afterwards to do her meerkat impression, though…

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…
