This was originally a Facebook comment, to one of my friends who had posted one of the original articles there, but a lot of other people in my circles are re-sharing the same articles, more general distribution of these comments is appropriate, and anyway Facebook is an untrustworthy platform. So, here's a repost. For necessary context, see the earlier articles from Edward Schlosser and Koritha Mitchell. Both of these articles have received a whole lot of circulation in the last few days, but I'm not sure they've received enough serious attention.
On this first day of 2015 I'm writing down some things that are important and that I wish people around me would know. There's nothing here that I haven't said before. My usual pattern is to say something and treat it as settled, because I expect everyone present at the time to remember it once they've been told. But not all of my friends have been paying attention to all of my writings for all of the decades I have been writing, and maybe at this time some repetition is appropriate. I wish I could have ten thousand readers for this and for all of my important postings. I may be lucky to get as many as ten readers. But if nothing else, the exercise of choosing what I want to say today is of some use to me personally, whether anybody reads it or not.
It's New Year's Eve in Copenhagen, and time for another update.

As I start writing this, it is the evening of November 1 and I am sitting in my new apartment on Hallandsgade, Amagerbro, Copenhagen. It'll probably be the 2nd before I can post it, because I don't have the Net here. It sure looks like Rabbi Schlomo Yitschaki was dead right about the tzaraath of houses. Now I kind of want to read the rest of his many volumes of commentaries on Jewish religious law.
In January of 2011, I had recently arrived at the University of Manitoba to work as a postdoc with Stephane Durocher. One of the first things he asked me to do was find out how many cycles there are in an n-dimensional hypercube graph, for general n. At the time, he and I both assumed that that meant spending maybe half an hour in the library looking up the answer.
Since then it's been more than three years; thousands of lines of computer code and months of CPU time; we added two more co-authors; we didn't solve the original problem, and didn't completely solve the other problem that we ended up working on, either; but here's a journal paper, anyway, and I think it's pretty interesting. The official definitive version will be free to access until mid-December and then will go behind Elsevier's paywall; the authors' accepted manuscript on arXiv is permanently accessible.
Read the paper if you're interested in the math details; in this entry I'm going to try to tell the story behind the paper, in relatively non-mathematical terms. I'm hoping it'll be of interest to my Web log readers and give you some idea, because I often get asked this, of what I actually do at work.
Every time I think I've seen it all with regard to Danish excuses, this place surprises me. Today's excuse is tzaraath.
I've been in Denmark just over a month, and I'm pretty stressed. This update is going to be somewhat disconnected. You can get some idea of what my experience has been like by watching the famous Bank Account Man commercial.
Denmark, being part of Europe, has a great deal of bureaucracy and many rules. However, the Danes are not really rule-followers. That at least is their reputation among people from other Nordic countries and I can see why. This is a list of excuses I've received from Danish people, mostly government bureaucrats. All are genuine, though some have been paraphrased from their more complicated original forms or to remove personal information. The list will be periodically updated.
