ESRI UK and GI in 2007

Wednesday, 31 January, 2007

I was leafing through GEOConnexion this month and skimmed through the article on predictions for 2007 in GI (usual culprits included Ed Parsons, Vanessa Lawrence, AGI, Autodesk, Cadcorp, Ian Dowman etc) and was staggered by the opening statement of Roger Waite, Managing Director of ESRI UK which said:

“For too long GIS has been a solution looking for a problem; this is set to change.”

I’m sorry but if my memory of GIS history is correct, we have the development of CGIS and DIME in the 1960s (along with the Experimental Cartography Unit in the UK), followed very shortly afterwards with the establishment of ESRI itself. These weren’t computer systems for the fun of it, but digital spatial engines designed for specific problems. GIS has never been a solution looking for a problem, rather a niche product that has had limited application, partly due to the high cost and consequently limited ROI.

I can’t help but think that ESRI is too busy looking over its shoulder to notice that Google (et al) is actually already in front. Look at Ed Parsons comments on Neogeography for a primer.

Dualit Coffee Maker Update

Saturday, 27 January, 2007

After two and a half years of faithful service my Dualit Espresso machine finally gave up the ghost. Many wonderful cups of coffee have been delivered by this machine, along with an awful lot of milk frothing. And the problem? A dead boiler, which meant I could have cold espresso and unfrothy, frothy milk. No good really. Being inquisitive I took the machine apart to see the neat, tidy and well made interior that I was expecting from Dualit. Unfortunately the boiler forms part of the sealed brewhead which was a no go.

I pondered buying a new machine, but with an original list price of 325 it seemed worth trying to get Dualit to fix it. After an initial enquiry, I gathered it would be 20-30 which I thought was incredibly reasonably. So I packaged the machine up and sent it back. Two weeks later I had heard nothing so phoned them to hear that it was in the workshop. The following day I took delivery of a brand new machine, free-of-charge. I can only assume it was beyond repair and that Dualit must stand by their products. So I am full of praise for both the product ethos and reasonable repair facilities that Dualit offer.

AllPeers Peer-to-Peer Networking

Wednesday, 24 January, 2007

Peer-to-Peer networking has been around for quite a while and is accompanied by the music industry’s paranoia concerning piracy. And they well might be right, but thats not the focus here. Rather businesses are starting to see the benefits of a variety of peer-to-peer networks and there are now a wealth of clients around using different network protocols.

One recent development in this area then is AllPeers, an Add-On for Firefox. So the first thing to note is that peer-to-peer is now integrated in to the browser, which in my opinion is a good thing. One piece of networking software to handle a variety of tasks. The second thing of note is that as a result, AllPeers takes advantage of the built-in SSL to offer encryption in file sharing. Finally, you have user-level control over the files you wish to share. Great if you want to make your holiday snaps available to just your Mum, whilst your stag-night video is only downloadable by those that attended!

So these are two huge advantages. AllPeers is currently in pre-release beta but offers a solid client that is highly functional. The system is server based in order to search for other clients and files. If they aren’t already on AllPeers then they are sent an email and, after downloading the plugin, can join in. As noted above, you can user level file permissions for sharing and it is as simple as dragging and dropping the file you want to share on to groups of users or individuals. Whilst it can be difficult to put a peer-to-peer UI within the paradigm of a web browser, All Peers have done a good job. As this is a pre-release version there are features still being added. An instant messaging client has recently appeared which is also pretty good.

And why might you want to use a peer-to-peer client? And why is this post in the GIS category? Well, I often find myself needing to file share spatial data with colleagues or students and as soon as they get too big for email (>10Mb) then it becomes a problem. In fact most of the time I drop back to sticking the files on a web server and emailing a link. All Peers adds convenience, encryption and permissions to help solve this problem.

Open Knowledge Foundation

Sunday, 21 January, 2007

The Open Knowledge Foundation is a not-for-profit organisation dedicated to addressing the utilisation of knowledge within a digital society and engaging in the wide and open availability of that knowledge. They are, not surprisingly, not in favour of restrictive practises in the availability of data/information. This clearly crosses paths with my work at the Journal of Maps and I broadly support such an initiative, particularly where it is able to raise the profile of the issues surrounding “open knowledge” and engage relevant stakeholders.

The OKF have organised Open Knowledge 1.0, the first all-day Open Knowledge event. The programme tackles data, media and government information and certainly looks interesting. If you have an interest in this area then it will be well worth a visit.

House re-wiring…. not really in the “fun” category

Wednesday, 17 January, 2007

I’ve had my house rewired recently and used Instalec, an electrical contractor in the Luton area. I was particularly concerned that a good job was done (I had had some good recommendations of several contractors) and, of course, that the quote was as low as possible. After having got a few quotes I chose Instalec based upon these two criteria. Saying that, they were the only contractor who didn’t come and look at the job. And they got a bit of a shock when they turned up and found the job larger than anticipated. They did do a good job, bar a few relatively less important issues, but I guess that is going to happen on all major jobs.

I then got the shock when the final bill came in at over twice the original estimate. I accept that estimates are ball park figures, but I can’t accept a doubling in the bill when at no point are you forewarned of this. Ho hum, the world turns. It does pay to be extra careful in getting anyone to work on any part of your house!

Einstein says it all: geography is much harder than physics

Friday, 12 January, 2007

I have to admit to really liking this quotation from Einstein:

“As a young man, my fondest dream was to become a geographer. However, while working in the Customs Office, I thought deeply about the matter and concluded that it was far too difficult a subject. With some reluctance, I then turned to physics as an alternative.”

It’s great and I oft quote it to people as to the complexity of natural systems and, consequently, the importance of geography as a subject (and, lets face it, we all like to be better than physicists. DIGRESSION: I should really carry on with the Einstein train of thought, but the physicist bashing is too tempting. I therefore digress to a quote that Otmar Buser ((I don’t think its attributable to him though) at the Swiss Federal Institute for Snow and Avalanche Research. He said that physicists are actually quite stupid; request an explanation about some physical effect (e.g. how do snowflakes form?) and then proceed to ask “why” to every answer they give. They won’t be able to get to six responses!!

Anyway, returning from digression. This would be all very well and good except for the small matter than Einstein didn’t actually say it. Ho hum, well it was good while it lasted. Now I am probably not the only one alive who thinks this quote is still attributable to Einstein and I’m certainly not the first one to realise that this is misquoted; in fact, it’s a(n) (innocent) hoax. Well after some digging it would appear that quite a few people in the mid-90s didn’t think this was a quotation from Einstein and it took until 1997 and, yes, GIS, to root out the truth (well, at least I think so!).

And the place to look is that oft read journal GIS World. Jerome Dobson also thought the quote odd and so mused about it in one of his columns. The result was a large mailbox in response and an admission from Duane Marble that he had composed the quote as a dig at the physicists in his building. And, as with Chinese Whispers, it had propagated from there. If you Google it all the top hits will show that this has been debunked, but there are still a good spattering of sites that do actually quote it (University of New England for instance).

Whilst GIS World has finished as a title, the back issues will be available online in the not-too-distant future. I’ll link to them then.

What degree should you choose?

Thursday, 11 January, 2007

This question has been posed to me in a variety of guises by, several different people, over the last couple of weeks and remains a perennial problem for students taking A-levels. It started out with a discussion on how best to recruit students and I mentioned that my wife (Middlesex University) had had considerable success in engaging six formers through the organisation of a revision conference. These are very popular and actually make money!! She had organised some lunchtime sessions, the most popular of which were on how to select a degree. This was then followed by a query from my niece as she was bewildered by the vast choice of degrees and locations. And from the discussion with her, the point was made that actually very few careers (and at the time we could only think of medicine) require you to take a degree in the particular subject area. Law, teaching and accountancy are all good examples of where you can cross-train with a conversion course (although if there are other careers then let me know). Indeed it reminded of a Steve Wright (in the afternoon) joke about how many DJs actually have a media studies degree. Or (in reverse), what careers does a sports science degree actually lead on to and how directly relevant is the academic content of the degree (and the sterotype is of people becoming PE teachers, which I am sure is both unfair and not true). Actually, my wife made the point that many vocational degrees need academic content to be validated at degree level, yet much of it is of little use to the career then pursued.

So thinking about this question got me pondering the poor recruitment that geography has seen over the last 6 or 7 sever years in HE. Geography went from very high numbers in the mid-1990s to a low in 2003/4 with a gradual rise since then. This is directly attributable to the drop in numbers of students taking geography at GCSE and A-level, a result of the introduction of more vocational style subjects at GCSE and A-level (business studies for example).

This somewhat rambling series of thoughts brings me back to the original question of what degree should you actually choose? Well in my experience most employers are concerned with the classification (grade) of your degree, not specifically the subject that it is in. First and foremost then you want to select a degree that you are good at and, perhaps more importantly, that you enjoy as a subject (and these both held true when I studied geography as an undergraduate). I also think, with my lecturers hat now on, that it is more beneficial to study academic rather than vocational subjects. This was partly why geography was so successful as a subject; it combined together science and social science and introduced students to a broad range of skills and experiences that were invaluable in the workplace. Vocational subjects have their place but not, in my opinion, at degree level. No doubt I stand to be corrected on this point!

Being a good lecturer needs….. more sex

Tuesday, 9 January, 2007

The BBC has reported (admittedly a year ago) on a study at the University of Paisley that was looking at the impact of different forms of sex on stress levels. Blood pressure was monitored during a variety of situations designed to increase stress, including public speaking. And the study found that participants who had had penetrative sex had reduced blood pressure and recovered from stress quicker than all other groups. The worst off were those who abstained from sex.

What does this mean for lecturers? Well I won’t spell it out, but I suspect our stress reduction courses don’t involve this kind of therapy ;)

Sense About Science

Monday, 8 January, 2007

It’s difficult to go a day without reading some loon story in the newspaper or seeing a reporter making ludicrous claims based upon flimsy evidence. Whilst as a scientist it can be relatively easy to “debunk” some of these stories (or find more reliable information about it), the “general public” are far less aware of the scientific arena and methods of research and subsequent reporting upon it. And for every opinion “!based upon evidence”, there is an equally compelling counter argument. Some “hot potatotes” include:

  • does smoking cause lung cancer?
  • is global warming occurring
  • what are the benefits and weaknesses of nuclear power
  • is stem cell research ethical
  • should we perform animal testing

The list is almost endless and there are no quick and easy answers. Thankfully the charity Sense About Science is trying to address the balance by presenting reasoned scientific information to the public. This is based upon a group of “grass roots” scientists who provide specialist input upon specific topics. The charity has a reading room of relevant titles for “public consumption”, as well as a phone number that people can call for further advice (and this includes, for example, any kind of employee, employer or civic group, not just the general public). There is also information relating to how the scientific process works, including a useful introduction to peer review.
