chance meeting

As I was travelling to Coventry yesterday, I spotted this fellow passenger on the train from Birmingham with a Valencia 9 bag, and a chat with him. It was a pure chance encounter as he was not attending our summer school, but continued down the line. (These bags are quite sturdy and I kept mine until a zipper broke.)

running by Kenilworth Castle [jatp]

Last week, while in Warwick, I had a nice warm afternoon run around Kenilworth in the fields with Nick Tawn, who brought us to this view of the castle from the West, by a former shallow lake called The Mere [lexicographically connected with La Mare rather than with La Mer!]. It also exposed the fact that my first and only visit to the castle was in the summer of 1977, with my pen friend from Birmingham. This was also the summer when Star Wars was released in Britain, including Birmingham where we first saw it…

back to Wales [54th Gregynog Statistical Conference]

Today, provided the Air France strike let me fly to Birmingham airport!, I am back at Gregynog Hall, Wales, for the weekend conference organised there every year by some Welsh and English statistics departments, including Warwick. Looking forward to the relaxed gathering in the glorious Welsh countryside (and hoping that my knee will have sufficiently recovered for some trail running around Gregynog Hall…!) Here are the slides of the talk I will present tomorrow:

[On an Air France flight for Birmingham, two young French students apparently studying in Warwick kept blathering the entire time, with an utter lack of concern for their surroundings. Note: Les Marseillais is a particularly idiotic reality show on French TV.]

  •  …j’ai arrêté de regarder les Marseillais, c’est même pas conscient, tu vois…
  • …grave, c’est sûr, moi aussi j’ai arrêté, j’avais trop d’épisodes à rattraper…

the Force awakens… some memories

In what may become a family tradition, I managed to accompany my daughter to the movies on the day off she takes just before her medical school finals. After last year catastrophic conclusion to the Hobbit trilogy, we went to watch the new Star Wars on the day it appeared in Paris. (Which involved me going directly to the movie theatre from the airport, on my way back from Warwick.) I am afraid I have to admit I enjoyed the movie a lot, despite my initial misgivings and the blatant shortcomings of this new instalment.

Indeed, it somewhat brought back [to me] the magic of watching the very first Star Wars, in the summer of 1977 and in a theatre located in down-town Birmingham, to make the connection complete! A new generation of (admittedly implausible) heroes takes over with very little help from the (equally implausible) old guys (so far). It is just brilliant to watch the scenario unfold towards the development of those characters and tant pis! if the battle scenes and the fighters and the whole Star Wars universe has not changed that much. While the new director has recovered the pace of the original film, he also builds the relations between most characters towards more depth and ambiguity. Once again, I like very much the way the original characters are treated, with just the right distance and irony, a position that would not have been possible with new actors. And again tant pis! if the new heroes share too much with the central characters of Hunger Games or The Maze Runner. This choice definitely appealed to my daughter, who did not complain in the least about the weaknesses in the scenario and about the very stretched ending. To the point of watching the movie a second time during the X’mas vacations.

[In the train shuttle at Birmingham airport, two young guys, maybe back from SPA 2015, discussing signal processing:]

– In Bayesian statistics, they use a different approach to testing hypotheses… You see, they put priors on the different hypotheses…

– But in the end it all boils down to concentration inequalities…

BibTool on the air

Posted in Books, Linux, Travel, University life with tags , , , , , , , , , , on October 23, 2014 by xi'an

Yesterday night, just before leaving for Coventry, I realised I had about 30 versions of my “mother of all .bib” bib file, spread over directories and with broken links with the original mother file… (I mean, I always create bib files in new directories by a hard link,

    ln ~/mother.bib

but they eventually and inexplicably end up with a life of their own!) So I decided a Spring clean-up was in order and installed BibTool on my Linux machine to gather all those versions into a new encompassing all-inclusive bib reference. I did not take advantage of the many possibilities of the program, written by Gerd Neugebauer, but it certainly solved my problem: once I realised I had to set the variates

check.double = on
check.double.delete = on
pass.comments = off

all I had to do was to call

bibtool -s -i ../*/*.bib -o mother.bib
bibtool -d -i mother.bib -o mother.bib
bibtool -s -i mother.bib -o mother.bib

to merge all bib file and then to get rid of the duplicated entries in mother.bib (the -d option commented out the duplicates and the second call with -s removed them). And to remove the duplicated definitions in the preamble of the file. This took me very little time in the RER train from Paris-Dauphine (where I taught this morning, having a hard time to make the students envision the empirical cdf as an average of Dirac masses!) to Roissy airport, in contrast with my pedestrian replacement of all stray siblings of the mother bib into new proper hard links, one by one. I am sure there is a bash command that could have done it in one line, but I spent instead my flight to Birmingham switching all existing bib files, one by one…
