Sean Riley creates the Computerphile YouTube channel, which has clocked up nearly a million subscribers, and produces some great stuff, especially for the geeks among us.
I had fun talking to him about the early days of the Trojan Room Coffee Pot.
This essay by Stephen R. Barley is a very nicely written commentary on the changing motivations of academic journals and institutions, and the effect it has on the disciplines they represent. Recommended for anyone involved in academic research, whether or not you’re in his particular field.
I rarely receive any comments these days on my findings, my data, or my analysis. In fact, I am usually complimented on these before being told why the paper can’t be published as is. Instead, the vast majority of comments focus on the theoretical or substantive frame of the story I want to tell. The logic of such comments boils down to this: “You say your paper is about X, but I think it is really about Y.”

Some of you may know that, alongside my normal consultancy business, I spend one day a week in the University Computer Lab for a change of scene. I’ve been doing this for a couple of years now, working on Frank Stajano’s Pico project, which is trying to create a better replacement for passwords, as the normal way to authenticate yourself to digital systems.
One of my roles in the project has been cameraman/video editor. Last year we produced the original video describing the project:
and just last month we did an update, which describes in more detail how the current phone-based prototype works underneath.
But I felt it was time for a change, so I’ve recently moved to a new project, which is in the so-called Rainbow group – somewhat nostalgic for me, because it’s where I did my Ph.D. about 20 years ago.
In this group, we’re looking at how we can improve the ways cars communicate with drivers, and, while the only web page about the project is somewhat limited at present, no doubt this will change over time…
Should be fun… more info in due course.
This chart appeared in a recent Economist blog post – I think it’s nicely done. It’s based on a study of U.S. university graduates, and the amount they earn over an extended period. The X-axis is a measure of the quality of the institution: roughly speaking, how easy it is to gain admission.
This shows some interesting things – at first glance. First, that Engineers, Computer Scientists and Mathematicians earn more than other fields, which seems only right and natural to me – and second, that the institution at which you study makes very little difference to your final earnings, which seems a bit less plausible.
But then I read the article more carefully. What this is actually plotting on the Y axis is the rate of return on your investment in the degree. If you had put the cost of your education into a savings account and left it for 20 years, what would the equivalent interest rate be? A rather mercenary way of thinking about education, perhaps, but intriguing nonetheless. If you’re studying business, maths or sciences, it’s an exceedingly good investment. If you prefer an arts subject, then you should – and probably will – find other ways of assessing the value of your education.
Now, in the States, a degree at Harvard, MIT or Stanford will cost you much more than one at Fred Bloggs College, and you will earn correspondingly more as a result of graduating, to the extent that the annualised return is roughly equivalent.
But it would be fascinating to see the same analysis done at British universities, where, for local and EU students at least, the tuition rates are capped and are the same at most institutions. (British students whining about their fees at our top universities should remember that they could easily be paying three times as much in America.) So I imagine the returns here would be rather higher, and the slope rather more pronounced.
There’s a wonderful-sounding position offered on one of the University mailing lists:
Equine Ambulatory Veterinarian (Maternity Cover)
I expect they’re looking for someone who specialises in a horse’s gait. Or someone who rides around in a horse ambulance?
But perhaps not. It’s much more satisfying to think that the University of Cambridge has always traditionally employed a walking midwife for horses, perhaps one of a small team of pedestrian veterinary specialists, and this is a once-in-a-lifetime chance to apply for one of these exclusive posts.
Regular readers will know that one of the things I’m currently working on is the Pico project, which is trying to find a long-term replacement for passwords.
I learned an interesting statistic yesterday from Angela Sasse: we recently passed the point at which more passwords are entered on mobile devices than on traditional computers, and that, on average, entering a password on a mobile device takes three times as long as on a laptop or PC.
This would seem to confirm our belief that the need for Pico, or something like it, will become more and more apparent over time.
