Stranger things have happened in C.

Worse than Nothing?

Saturday, May 27th, 2017

Here’s a thought, which came from a conversation with Richard Harvey t’other week. Is it possible for a degree to harm your job prospects? The example that he came up with was a third class degree in some vocational or quasi-vocational subject such as computer science. If you have a third class degree in CS, what does that say to prospective employers? Firstly, that you are not much of a high-flyer in the subject—that is a no-brainer. But, it also labels you as someone who is a specialist—and not a very good one! The holder of a third in history, unless they are applying specifically for a job relating to history, isn’t too much harmed by their degree. Someone sufficiently desperate will take them on to do something generic (this relates to another conversation I had about careers recently—what are universities doing to engage with the third-class employers that will take on our third-class graduates? Perhaps we need to be more proactive in this area, rather than just dismissive, but this requires a degree of tact beyond most people.). But a third-class computing/architecture/pharmacy student is stuck in the bind that they have declared a professional specialism, and so employers will not consider them for a generic role; whilst at the same time evidencing that they are not very good in the specialism that they have identified with. Perhaps we need to do more for these students by emphasising the generic skills that computer science can bring to the workplace—”computing is the new Latin” as a rather tone-deaf saying goes.

3D vs. 2D Worlds

Tuesday, May 16th, 2017

What is the habitable surface of the world? Actually, that is the wrong question. The right question is “What is the habitable volume of the world?”. It is easy to think that the ratio of marine habitat to land habitat is about 2:1—that is what we see when we look at the globe. But, this ignores the fact that, to a first approximation, the oceans are habitable in three dimensions, whereas the surface of the earth is only habitable in two. This makes the habitable volume of the seas vastly larger than our surface-biased eyes first intuit.
