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.

for new year’s eve, we traveled to oldenburg. on the way back and forth, we saw some interesting things in osnabrück. finally, on the way to dresden, we saw a historic train of the deutsche reichsbahn in leipzig. here are some impressions.

it’s white outside. for a couple of days now. after a few white days during october, and rather warm temperaturs during most of november, the coldness finally returned, and with it the whiteness. an unfortunate companion of snow is ice, and by now, there’s plenty of it. mostly on sidewalks, sometimes on the roads. let’s see when the next chinook is coming.

often, i experiment when cooking. adding or removing or exchanging ingredients, changing the result a little every time; i guess this is not that uncommon for anyone used to cooking. sometimes, i do some more experiments, like today. two days ago, when shopping, i got a spontaneous idea, namely to try a omlette with zucchini and cheese. well, i bought everything i needed, but on the way home, i continued to think and planned to replace the omlette by pancakes. well, and today, i finally tried it out. first, i cut the zucchini into small slices:

then, i prepared pancake dough – flour, a few eggs, salt, milk, and mixing it together. then, i started baking pancakes.

for the first try, i took the done pancake out of the pan and placed it on a plate. i added grinded mozzarella on one half, put on some of the zucchini slices, and flipped the other half over:

it tastes good, but i thought i can do better. so i tried to add some spices, in particular cayenne pepper, after putting the cheese on. i also put on the cheese while the pancake was still in the pan, as otherwise the cheese doesn’t really melt. it then looks like this:

finally, i had a small stack of pancakes, part of whom i enjoyed eating, while putting the rest in the fridge to enjoy it at tomorrow’s lunch.

after watching shakespeare’s a midsummer night’s dream, we walked around on prince’s island park, near to the shore of the bow river. the shore area is really nice, it is green while being mostly deserted from mankind. lots of green corners, where one can hide, even though the surrounding freeways are still audible.
here are some impressions:

on friday evening and saturday afternoon, i witnessed two performances of with shakespeare in the park, namely romeo and juliet and a midsummer night’s dream. the performances took place in prince’s island park, which i already displayed twice in this blog. both plays were near to the original text, but in a modernized setting. i enjoyed both a lot!
i did not have my camera with me while watching romeo and juliet, but i had it with me for a midsummer night’s dream. here are some impressions:

last saturday, i was spending the afternoon and evening with a guy from the netherlands who is vegan. hence, for lunch and dinner, we tried to find vegetarian/vegan restaurants. he brought a list from happy cow, and for lunch we decided to go to a vietnamese place called white oak ii. it features a large variety of vegan vietnamese and chinese food, often things which originally contain meat, but where the meat is replaced. this was really amazing. the restaurant is placed in a small vietnamese mall, not obvious to find. i definitively have to go there again.
for dinner, we went to the coup, a vegetarian place at 17th avenue. this was a bit more pricy and stylish, but also very good. a place i also have to go to at least one more time. i had a vegetarian burger there, in fact the first vegetarian burger i ever had: it was really good! as was the spiced (in the sense of chili!) iced chocolate shake (hmmmm) and a cocktail called the “malibu barbie colada” which, despite its funny name, tasted fantastic. for dessert, i had a piece of organic chocolate torte, which in fact is vegan.

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.

if you’re from europe, you probably know quark. if you’re from northern america, you probably don’t, as it’s essentially impossible to buy it here. well, there are some exceptions, for example dutch/german shops which happen to be around somewhere. mixed with milk and sugar, and with other ingredients such as strawberries, it gives a nice, refreshing snack or even whole dinner. i just love it.

a few days ago my hispeed internet started to be slow. after a short time, i got the impression that the network itself was fine, but the dns lookups are slow. some minutes ago, i decided to investigate this problem a bit more in detail. indeed, host turns out to be really slow when looking up domain names, and if i enter an ip address in firefox instead of a domain name, accessing the page is really fast. searching the net for this problem, i found nothing except a list of shaw dns servers. the ones listed there for calgary differ from the ones entered in /etc/resolv.conf; more precisely, the last byte reads 143 and 145 instead of 133 and 135. to try it out, i changed the values, and voila, host ran in hispeed again. restarting firefox also allowed to access the world wide web fast, again.

well, last friday i was visiting stuttgart’s wilhelma with a friend of mine, when after some time, my camera (a nikon d40x) stopped working, only displaying “error: press shutter release button again”. after trying a lot of things and searching the web, and finally contacting the support, it looks like i have to send the camera in for repair. so right now i’ll be without a camera for some time… :-(
