travel madness

Posted in Kids, Running, Travel with tags , , , , , , on August 3, 2016 by xi'an

Certainly the 43 hours trip to San Francisco on Friday and Saturday was one of the worst travels I ever experienced as we were delayed, disembarked and left waiting in queues for most of two days. The August vacation peak weekend “coincided” with an Air France strike action by flight attendants and a correlated lack of ground personal in the airport. Rather than cancelling flights, Air France chose to downsize the number of passengers on board depending on the available flight attendants on that flight, which is presumably less expensive for the company. And so nice for the disembarked passengers, frequent fliers included. This was the Friday morning flight. We got rebooked to the Friday afternoon flight. Meaning six hours in the Air France lounge. After one hour delay, the afternoon flight rode for about 100 meters when leaking fuel was detected, apparently due to overfull tanks. Getting this sorted took around three hours, after which the captain told us that labour regulations prevented him and the crew to fly to San Francisco as it would be too long a working day. The whole plane was disembarked, which took another hour, to a transit area with hundred of people and no airline representative. Eventually someone from Air France appeared and started talking to people around rather than making a global announcement. Herding us back outside the restricted area with vague indications to get to another part of the terminal for rerouting. After more delays and chaos we ended up in another queue for hotel vouchers as the only choice was to wait for a specially chartered plane at noon the next day, our baggage being sealed and inaccessible. It took hours to get those vouchers and reach the airport hotel by midnight, before rushing back the next morn to another vaguely specified rendez-vous. This worked out more smoothly, except for another three hours delay waiting for enough flight attendants to show up.  This ruined our chances to get there in time to recover material for the race. Fortunately, our son managed to board an earlier plane [if last on board!] and grab it for us.

The worst thing about this [first world problem!] trip was not the strike or the cancellations, but the complete disorganisation of the management of the issues, with the passengers being herded from one place to another with contradictory items of information by clueless airline representatives. I figure this may be a consequence of the strike as well, the airport desks being poorly staffed for a major vacation weekend.  [Again, first world problem, no one was hurt and we just lost one vacation day. Plus the opportunity to write half a dozen posts.]

off to Northern California

San Francisco, Aug. 05, 2010Before attending MCqMC in Stanford in two weeks, I will take some vacations in Northern California [really North!] with my family. Starting with the San Francisco ½ marathon tomorrow. So expect delays [as we already got stuck six twenty-seven thirty hours in De Gaulle airport thanks to a strike!] and mostly non-statistical entries on the ‘Og. And pictures.

trip to München

While my train ride to the fabulous De Gaulle airport was so much delayed that I had less than ten minutes from jumping from the carriage to sitting in my plane seat, I handled the run through security and the endless corridors of the airport in the allotted time, and reached Munich in time for my afternoon seminar and several discussions that prolonged into a pleasant dinner of Wiener Schnitzel and Eisbier.  This was very exciting as I met physicists and astrophysicists involved in population Monte Carlo and parallel MCMC and manageable harmonic mean estimates and intractable ABC settings (because simulating the data takes eons!). I wish the afternoon could have been longer. And while this is the third time I come to Munich, I still have not managed to see the centre of town! Or even the nearby mountains. Maybe an unsuspected consequence of the Heisenberg principle…

BibTool on the air

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…

Bangalore workshop [ಬೆಂಗಳೂರು ಕಾರ್ಯಾಗಾರ]

Posted in pictures, Running, Statistics, Travel, University life, Wines with tags , , , , , , , on August 3, 2014 by xi'an

IISc2As I am now back home after a rather lengthy and somewhat eventful trip [getting too early to Bangalore airport with 3 hours to spend in the nice and very quiet lounge, followed by another 5 hour wait in the very nice but no so quiet Bombay airport lounge, no visit to the cockpit this time!, and then the usual sick passenger blocking all trains from Paris-Charles de Gaulle airport for one hour, reaching home to find my 97-year old neighbour fallen in her kitchen and calling for help!], I cannot but reflect on the difference between my two trips to India, from the chaos of Varanasi to the orderly peace of the campus of the Indian Institute of Science of Bangalore and even to some extent of the whole city of Bangalore, all proportions guarded. Even managing to get a [new] pair of [new] prescription glasses (or rather spectacles) within three days!

I thus found this trip much less stressful and much profitable, from enjoying the local food to discussing with Indian statisticians. The purpose of the IFCAM workshop was to bring both groups together for potential joint projects funded by IFCAM (at the travel level). While I found most talks were driven by specific applications, esp. in genomics, there are directions where we could indeed collaborate, from capture-recapture to astrostatistics. So it may be that I’ll be back in India in a near future!
