Happy New Year, everyone. The blogging was light due to a nice holiday break with the family. Now we’re all back home… and I’m taking off again. This time, I’m headed to the Joint Mathematics Meetings in New Orleans from January 5 through January 8. I tend to do more with my Twitter account during conferences than I do with the blog, but hopefully I can give you some reporting along with some of the processing I usually do following good conference talks (and even some of the bad ones).
I’m giving two talks while in New Orleans:
- On Thursday at 3:55, I’m speaking on “A Brief Fly-Through of Cryptology for First-Semester Students using Active Learning and Common Technology” in the MAA Session on Cryptology for Undergraduates. That’s in the Great Ballroom E, 5th Floor Sheraton in case you’re there and want to come. This talk is about a 5-day minicourse I do as a guest lecturer in our…

…I’m all done with the ASEE and headed off on vacation in nearby Holiday World. Whatever it is I’ve left out about ASEE, I hope to fill in once I’m back home. If there’s something specific you’d like to know about what I’ve seen here, let me know in the comments.

This blog used to have two different URL’s — castingoutnines.wordpress.com as well as castingoutnines.net. The latter was a holdover from the days I self-hosted this blog, and when the domain name registration period drew to a close in December of last year, I opted not to renew, since I think most people come here from an RSS feed or otherwise use the WordPress.com domain.
Well, that might have turned out to be a mistake, because as JackieB on Twitter informed me earlier this evening, someone has purchased the castingoutnines.net domain name and is using it to plagiarize content from here. I’ve spent about 90 minutes just now going through the “fake” CO9′s site, and all totalled, there were 53 blog posts copied in their entirety from here, and the “About” and “What is Casting Out Nines?” pages. Of course I was not given attribution for any of this.
WordPress.com has this helpful page…

Last night I received this email from my colleague Dan Callon, who is at the Joint Mathematics Meetings in San Francisco:
I went to a session at the national joint meetings tonight on Wolfram|Alpha, sponsored by the MAA Special Interest Group on Mathematics Instruction Using the Web, with speaker Bruce Yoshiwara of Los Angeles’ Pierce College. He cited the blog of the best-known expert (outside of Wolfram itself) in the country on using Wolfram|Alpha in education: Robert Talbert. Congratulations!
I would have to rank Maria Andersen way above myself both in terms of her expertise with W|A and in terms of how well-known she is, but still, I’m honored by Prof. Yoshiwara’s mention. And I’ll keep trying to crank out relevant posts about Wolfram|Alpha in the future.

Greetings, everybody. Is anybody still out there? It’s been a while. What started as a simple drop-off in the number of posts I was making here at Casting Out Nines turned into a five-month sabbatical from blogging at all. The peace and quiet was nice. But now I think I’m ready to get back into things. I just wanted to take this post to announce this, and to point out a few changes here at the blog and give a rundown of some of the things you can expect to see here.
If you’re reading this on the actual web site as opposed to an RSS reader, you will see a new layout and theme for the blog that should make it easier to find things and browse content. You will get a different set of stuff in the right sidebars if you are focusing in on a single article rather than looking at the main blog page. Among the new features I’ve activated is the ability to rate individual blog posts; to do this, …

Two of my last three posts have shown up in Google Reader being completely illegible. For some reason some of the text is being bunched up on the left side of the post. I don’t know why it’s doing this, and I don’t know if I can go back and re-post and have it be fixed. This might be happening because I drafted those two articles using a text editor and then cut-and-pasted into the WordPress.com editor, and although I can’t see why that should be a problem, WP.com’s editor is not well-known for its robustness. Anyhow, hopefully this post (being written entirely inside the WP.com editor) will come through OK. If it does, and you subscribe to my feed using Google Reader and couldn’t read my two posts, please just click through the Google Reader feeds to the main articles. They do show up fine on the main blog site.
For everybody, I’ll be putting up some test posts to see if my using a…

First of all, you may have noticed I am again posting after a lengthy hiatus following the birth of our third child. He’s 5 weeks old now, and we are beginning to return to some kind of routine in our lives that includes him. For the first month, as all parents know, you’re basically in survival mode, catching sleep when you can and trying to get your work done elsewhere. He’s nowhere close to sleeping through the night but at least we’re managing better than we were, and I’m on top of things enough at work that I have the time now to write some posts and at least schedule them for future posting, so I have the appearance of posting once a day. Anyhow, I just wanted to say thanks for all your well-wishes and prayers and for your continued reading of my little slice of the interwebs.
Also, you’ve probably noticed some cosmetic changes here. I’ve changed themes to the new “Vanguard” theme…

Apologies for the light blogging for the last couple of weeks. As longtime readers know, I’m on our Promotion and Tenure Committee here at my college — this year I’m the chair of this committee — and we do all of our work reviewing portfolios during the month of January while the rest of the college is doing Winter Term. It’s always a challenge to manage our work so that we get all of our recommendation letters written in a reasonable amount of time, but this year there are some personal reasons that have added an extra sense of urgency.
So ever since the first of this year I’ve been spending all my time either doing these P&T reviews or trying to cram in course preps for the spring (two sections of Calculus and a section of Linear Algebra), in an attempt to get as much done as possible before the baby arrives (click on the link above for the backstory). I don’t think anybody wants me…
