One kilopost!

Blogging is light right now because I’m on sick kid duty at home. But I wanted to check in to mention that this post is the 1000th post I have made here at Casting Out Nines. I’ve been thinking I need to say something stupendously wise for such a milestone, but I think that’s putting too much pressure on me, as I am accustomed to neither stupendousness nor wisdom. So instead, I just wanted to note some cool stats about the blog:

  • As I said, this is the 1000th post since the blog’s inception on December 3, 2005. That was 949 days ago, so I’ve averaged right at one post per day for 2.5 years. That’s been pretty much my goal for posting and will remain so.
  • This blog has had a total of 9,568 approved comments. That’s an average of about 10 comments per post, which is stat I am particularly pleased with, as it indicates that CO9s is not an echo chamber, as so many blogs are. The median amount of comments per post is probably more like 0 or 1, but at least occasionally there are substantive conversations that arise from the posts here, and I’m very humbled and thankful for that.
  • The Akismet filter has blocked 42,159 spam comments, not counting the 38 that are in the queue right now. I think a spam-to-legitimate comment ratio of 4.5:1 isn’t too bad for a blog these days.

So instead of something stupendous, I’ll just say “thanks” to all readers and commenters, past and present, who have made blogging here such a satisfying and educational experience.

Calling all student bloggers

The comment on yesterday’s post from Matt, an undergrad in math and computer science at Carnegie-Mellon and blogger at Relatively Speaking, reminded me of just how much I appreciate blogs written by students. As a professor, my job on the “micro” scale is to design and teach mathematics courses and do stuff to help the college operate. But my vocation on the “macro” scale is to help students to think well and to chart their course through life. I like to think that blogging is an extension of that vocation beyond my everyday campus role, and it always excites me to be able to interact with students like Matt who are working hard at the business of learning.

So I’d like to ask any student blogger — especially undergraduates but also high school/homeschool students and graduate students — who is actively maintaining a blog that seriously reflects on their studies and their lives to leave your URL in the comments to this post. I don’t have a blogroll around here — maybe I should? — but I would certainly like to add you to my RSS feeds and keep up with what you’re doing.

And perhaps other readers who are similarly interested might like to glean those URL’s from the comments as well. Who knows, perhaps we can one day have some kind of “Carnival of Undergraduates” or something.

A math-blogging revelation

I’ve just made a major discovery: WordPress.com blogs, like this one, allow you to typeset LaTeX directly in your blog posts. For example:

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

You can put in LaTeX in the comment fields, too. Here’s the FAQ entry that explains it all.  I’m appreciating my switch to WordPress.com more and more each day.

I found this fact out in a comment left by  Terence Tao on the blog of Timothy Gowers, both of whom are not only Fields Medal-winning mathematicians but also WordPress.com bloggers.
