after attending the joint mathematics meetings in san francisco, i want to share two points you should not try to copy when you’re organizing a conference.

• in case you have a lot of parallel sessions, try to schedule sessions with similar topics in parallel. this minimizes the number of days people from these areas have to attend the conference.
• promise wireless internet, but do not provide a backbone which can handle this. after noticing it is too slow, simply turn it off for the rest of the conference.
• this applies more to conference center owners. do not install power plugs anywhere near to areas where tables and seats are placed. and by any means, never install power plugs in rooms where talks are held.

people will really appreciate this and regard your conference as one of the best ever.

last week tuesday, i attended the first non-classic concert this year, namely the calgary instantiation of the progressive nation tour 2009, featuring dream theater, zappa plays zappa, bigelf and scale the summit. originally, pain of salvation and another band should have played instead of bigelf and scale the summit, but unfortunately they had to pull out due to some side effects of the financial crisis. too bad, i would really have liked to see pain of salvation.
i decided to spare my energy in particular for the last two bands, and hence skipped scale the summit. the announced timing for the conference was perfect, and so i arrived directly when bigelf began to play. they were ok, but i was more waiting for the next band. and the very bad part of the evening started during their gig (maybe even before, but i wasn’t there), namely some [insert your favourite curse word here] potheads started smoking weed. it was not as bad as last year, but still very annoying. why can’t these idiots smoke somewhere where they don’t annoy anyone? at least there was no moshpit and the crowd’s density was really pleasant.
after hearing so many good things about them, i was really happy to finally see zappa plays zappa, which is not just another frank zappa cover band, but founded and lead by one of zappas sons. (not that this makes a difference to me, as i have no comparism of zappa plays zappa to other frank zappa cover bands.) i really enjoyed their performance – even though the potheads annoyed the hell out of me.
finally, dream theater entered the stage. they played several songs from their new album, but as usual also a lot older songs, everything including some improvisation and extensions, and several solo performances between the songs.
the concert was really good, even though the potheads repeatedly tried to ruin the whole thing to me. the only way to make it better would be to throw the potheads out and re-add pain of salvation (and maybe reduce to three bands, all of which can play a bit longer in that case).

the last two weeks were pretty much packed with two conferences and a summer school. on august 13–14, i.e. thursday and friday, the selected areas of cryptography conference was held in calgary. then, the week after that, the ecc summer school was held from wednesday to saturday, and from sunday afternoon to wednesday the 13th workshop on elliptic curve cryptography was held. (in fact, this was the sixth ecc workshop i attended, beginning with the one 2004 in bochum. and the second ecc mentioned in this blog; apparently i was too busy to write something about the 12th one held in utrecht last year.)
in addition to these things, several more things happened, some about whom i might write a few words in some more posts.

today, we had our conference dinner at an italian restaurant called l’espresso. the atmosphere was nice and the food was good, and after the dessert espresso, coffee or cappuccino was served. i asked for hot chocolate itself, and the waiter said he has to check whether that is ok, since they use high quality chocolate which is a bit more expensive. that already sounded good, so i told him in case of doubt i’d pay for that one myself. some minutes later, i got my chocolate (without having to pay for it), and i must say, it’s the best hot chocolate i ever had. i guess it was made in a similar manner to the one i once produced myself. if i ever come back to toronto, i have to get back to this place :)

this week, i was attending the ants. that’s not a conference on ant colony optimization and swarm intelligence, but the eighth instance of the algorithmic number theory symphosium, held in banff, canada.
banff is situated in the canadian part of the rocky mountains, whence one has a pretty neat sight:

here are some impressions from the conference center facilities. the first is a shortcut to the dining hall, the second the professional develop center, and the third one a pathway inbetween:

the next two photos show a view from inside the professional develop center, where we were housed, and me together with my poster:

this conference has been really great. i had lots of fun, learned a lot, met a lot of nice folks (again). and some more.
