The answer to this is unquestionably yes. I’ve been walking in the Scottish mountains regularly since 1993 and in that time I have noticed a definite change in the mountain environment, specifically the conditions in the winter months. Since about the year 2000, the number of trips during the winter months where I have needed to use my ice-axe and crampons to get to the summit of a mountain seems to have reduced noticeably. This is not only due to decreased snowfall and higher temperatures, but also because several of the winters in recent years have had spells where a major thaw has occured, and it has become possible to walk to altitudes of 1000 metres and higher and encounter no snow or ice at any month of the year. This happened when I climbed Ben Starav in February recently.
My previous posting, ‘Is global warming really caused by human activity‘ caused some debate, notably on the Scran Scribble discussion forum. The television documentary that prompted my posting has also generated a lot of discussion, and the blog of the science journalist Ben Goldacre (who writes for the Guardian) contains a good sampling of the debate and gives one a flavour of the many issues surrounding this topic.
I’ve just returned from a 4-day trip to Amsterdam with my girlfriend Lesley. It was the first time I’ve been there, and it definitely lives up to its reputation as a purveyor of all sorts of temptation, but Lesley and I were really there for the beer and food. We ate falafel and flemish-style chips (with mayonnaise and curry sauce) in the street, ate in Indonesian (sensational Nasi Goreng), Argentinian (steaks), Chinese and Japanese restaurants, had freshly-squeezed orange juice for breakfast every day, sampled an authentic Dutch apple pie, and it was all amazing, and reminds me of why Scotland is such an impoverished nation when it comes to food. We weren’t even able to escape Scottish misery because as we were eating chips on the Dam square, a bagpipe player in full regalia started playing for the crowds of tourists. Inexplicable, really. However, the weather was definitely not Scottish, with blue skies for the whole time we were there.
Last night there was a documentary on Channel 4 (one of the main broadcasters on UK television), that essentially asked the question above. It was shocking and startling. There seems to be a very good chance that the answer to the question is no. Many atmospheric, oceanographic and biological scientists were interviewed, and they were not from the scientific fringe, they were from mainstream academia. All are of the opinion that the widely-held belief (for that is what it seems to be, a belief) that CO2 emissions from human activity cause global warming, is based upon bad science, and after viewing this program I agree with them. There are other theories about what causes global warming, most notably solar radiation, and for which the scientific evidence is more compelling than that for CO2 emissions.
For the last seven years of my professional life, one issue has dominated above all others, and that is metadata. Metadata is a simple notion really, that of describing things in a summarised fashion so that they can discovered by searching catalogues and then used in a practical way. A library book index is an example of metadata, as is a telephone directory.
Following on from my post ‘Why I love Google Maps‘, the data from the Google Maps service is also very commonly used to create ‘mashups‘. This is becoming a fashionable term for commentators to bandy about when talking about interesting new websites, in much the same way as the label ‘web 2.0′. Unlike ‘web 2.0 ‘ however, the term mashups has a strict definition, involving combining data from disparate, unconnected sources on the internet, into an original format that adds value in the way that the data is combined and presented (graphically in the case of Google Maps), is something that is new, and is perhaps something that the original generators of the data did not envisage it being used for. Having data that is freely available through internet-based interfaces that are adequately defined is of course a prerequisite for this.
Last weekend I spent a couple of days in Cheltenham visiting an old school friend, John. I had a great tour of most of the pubs and clubs and can confirm that yes, the place is small and peaceful, and just a bit upmarket (maybe too much for an unsophisticate like me), whilst at the same time having good nightlife. It’s also a bit of a shock to spend the evening in smoky pubs – I have got used to Scottish pubs and waking up the day after not reeking of tobacco. It’s all change for England too in the summer though.
One of the issues a software engineer who develops HTTP interfaces (i.e. websites) as part of their code has to consider is ‘accessibility’. This catch-all term covers many things but essentially means that a website must be implemented in such a way that no-one is excluded from using it. It’s often thought of as purely a website graphical design consideration but it is absolutely something that a coder has to consider.
In the organisation where I am employed there is a dual, almost schizophrenic, nature to the work that I (and the other software engineers in my team) do there. Our funding comes from several sources, but a large portion comes from academic research councils. The nature of this funding is that it involves short-term projects that focus on research materials and on developing internet technologies to deliver those resources to the academic community in the UK in novel and groundbreaking ways. To do this work requires a specific type of software engineer, and one who is happy to take on new challenges where there is little supporting documentation (because very often no-one else in the whole world is doing quite the same thing), a very small but knowledgeable audience of users (typically research academics and information specialists like librarians and archivists), and where the limitations of the funding require that all the software development (and sometimes the project mangement too) are done by exactly one person, perhaps on a part-time basis.
I spend a lot of my time working with and developing Geographic Information software, especially graphical mapping applications. Recently I have been working a lot with the mapping data and JavaScript API provided by the Google Maps service, and I am very impressed with it. It’s very simple to use, and makes adding mapping capabilities to a website a breeze. I’ve used it extensively to display GPS data I’ve collected whilst hillwalking, an example of which can be seen here. A book I found very useful for helping with this was ‘Google Maps Hacks‘ from O’Reilly (my favourite publisher).
I am a software engineer / database administrator / web developer living in Edinburgh, Scotland. In my spare time I like to travel and take photographs (especially of mountains). See my main website here: Eddie's Photo Archive
