We are hiring again. I am looking forward to interacting with two new colleagues in Mathematical Biology soon. In addition, we have also advertised a statistics lectureship.

+Ben Lambert , a private tutor and Ph.D. student in computational biology in Oxford, has made Khan Academy style videos constituting a course in econometrics. I listened in on the first few lectures on multi-linear regression and they were very clear and would be very accessible to our second-year undergraduate students at York. He also has an undergraduate version that will probably be suitable to recommend to my students when I teach our first-term Introduction to Probability and Statistics again in the autumn.

I found out about these video lectures because Ben Lambert had an ad for them running before the latest Minute Physics video on YouTube. What an enterprising Ph.D. student!

I was never quite sure whether I should use +ShareLaTeX or +writeLaTeX for online LaTeX editing and collaboration. Now ShareLaTeX has gone open-source and I think that settles it for me. I bought a subscription to their hosted service to send a signal that I support this move to open source.

Recently, the email addresses and passwords of 16 million Germans (including my wife) were discovered on botnets.  That illustrates how important it is to use two-step authentication on all services that have access to your private data, so that in addition to the password a hacker would also need your mobile phone to authenticate. In my case the services that have the most access to my private data are Google and Dropbox. I had turned on two-step authentication on my Google account a long time ago, but I only just discovered that two-step authentication is also supported by Dropbox. 

The link below takes you to the dropbox page where you can enable two-step authentication.

Conveniently, to generate the time-sensitive codes for Dropbox I can use the same Google Authenticator App on my phone that I already use for Google.

The official DropBox help https://www.dropbox.com/help/59/en indicates that it will fail. But what I don't know is how it will fail and the various what-ifs (what if we started sharing a folder and I try to copy something into it that is larger than the remaining quota of  my collaborator? does it fail for me or for him or for both?)

Is more always better when it comes to consumption and economic growth?
The introduction to this book is worth reading (as is the entire book, but it is expensive while the introduction is available as free sample). I quote the first two paragraphs:

"If you ask a chef, a physician, or a teacher the question: ‘‘Is more always better,’’ they will probably answer: ‘‘No’’. Of course, it depends on the dish you are cooking, the illness you are curing, and the subject you are teaching. But these professionals know when additional ingredients spoil the dish, additional treatment harms the patient, and additional learning material frustrates the student. If you put the same question to an economist or a consumer, though, it is less clear what the answer will be.

Nowadays, consumers seem to have an insatiable desire for more and more goods and services. Economists typically equate more consumption with greater well-being. And growth has become a leading commercial and political imperative. As a consequence, Frank and Cook (1995) have described advanced societies as ‘‘winner-take-all-societies’’ in which a few superstars are paid handsomely, and others are seduced into mimicking their grand lifestyles (Frank and Cook 1995). In this environment, maximization of consumption has become the hallmark of success. More is universally taken to mean better, but here we ask whether more actually makes people happier."

The book investigates the question thoroughly from many angles in 14 chapters contributed by academics from several disciplines: economics, psychology, philosophy, neuroscience, politics, biology, social sciences.

Thanks to +Heike Barndt for recommending this book to me.

Cal Newport gives very good advice when he tells us not to believe the currently fashionable idea that one first has to figure out what one is passionate about before one can choose a career path.

Most jobs have their good, interesting aspects if you just look. All jobs have bad bits you just have to suffer through. And by and large the job you do is less important for your happiness than the social climate - the coworkers, the power structure, the working hours - you work in.

Our final-year project students are now using the Easter break to write their project reports. In our last meeting I briefed them on the importance of being both clear and concise in their writing. I wish I could have been as eloquent as Schopenhauer in formulating this advice.

:-) Yes, Schopenhauer's prose is pleasant to read but not brief. A more useful place that I direct some of my students to are the first few lectures in the course "Writing in the Sciences" at https://www.coursera.org/course/sciwrit

If I should find myself with enough time in the evening when I am in Barcelona next month, rather than going to a restaurant I would much prefer to have dinner with locals. This will be easy to arrange via EatWith.com, which is a sort of Airbnb but for eating rather than sleeping. I really like the idea. It will make travelling so much more interesting. I hope EatWith will take off in many places. The offerings are a bit sparse in the UK so far, at least compared to Barcelona. Have any of you tried it yet?

Quite a coup by Glasgow University students to get Snowden to stand for election as their next Rector. 
+Lukas Delius , who are you going to vote for?

+Lukas Delius , you are right that Snowden will not actually be able to fulfill the duties of a rector. But I still admire the group of students who had the idea and managed to contact Snowden and convince him to stand for election. If nothing else it raised the profile of both Glasgow University and of Snowden by getting both into the national media again. Also it probably raises the interest among students in the elections of the rector. If that group of students could now also get Snowden to get active in an election campaign that would be even better. Snowden is rather quiet.

Introduction
My background is in Quantum Field Theory, String Theory, Integrable Systems and Quantum Groups. My current research is in transferring some of the methods of these fields to theoretical ecology.

Two concrete current research topics are:
  • Scale invariant size spectrum models of the pelagic ecosystem.
  • Modelling extinction trajectories in microcosm communities.
I also have a wider interest in stochastic processes and complex networks.

Mein Haar wurde von Svetlana geschnitten. Sie hat das hervorragend gemacht. Zusätzlich war sie vergnügt und lustig im Gespräch. Auch hatte man nicht den Eindruck, dass sie versuchte, schnell fertig zu werden, sondern sie legte Wert auf gute Arbeit. Bei einem Preis von nur 14.50 Euro keine Selbstverständlichkeit.

I am writing this review while relaxing in a hammock on the garden of the farmhouse, listening to the sounds of the cicadas in the trees above. It is idyllic. This place is ideal for families. After an evening chat on the porch admiring the fire flies and stroking the kittens we retired to the common room, watching the Olympics on the large tv. We had a good night's sleep in a room with a queen bed and two single beds for the children. The breakfast was excellent with a huge variety. There was so much of it that we could not possibly eat all of it but luckily the remainder did not go to waste: my children were encouraged to feed the goats and the chickens, which was a lot of fun. Now the daughter of our hosts has taken my children to have fun on a barn house swing. The hosts are very friendly and we feel very welcome here.

Excellent. I was there with my wife and teenage children and we all found something interesting on the menu (whereas in other restaurants my children are usually tempted to go with the safe familiar but boring options). The four dishes that we ordered were very different and all very good. We got the seat by the window and it was nice to look out onto the church which was illuminated in the evening sunshine. A thoroughly enjoyable evening.

I am using Plumbforce Direct regularly when there is a problem at my rental property because of their extremely efficient and friendly customer service. They have always been very fast at arranging a visit by a plumber or heating engineer. The same lady from the customer service team deals with me each time and whenever there is a problem she is very responsive and very efficient at resolving it. On one occasion the charge for fitting a Magnavox filter had exceeded the initial quotation. I had only to mention it and she arranged for a refund to my credit card. On another occasion the engineer came outside the agreed time window and as a result I was given a £25 discount. My tenant is happy with the service of the engineers that Plumbforce Direct is sending.
