The Good News: my paper "Mashups for course websites with Yahoo! Pipes" was accepted to the MAA Session on Harnessing Mobile Communication Devices and Online Communication Tools for Mathematics Education to be held at the Joint Mathematics Meetings in January in New Orleans. It will be good to see talks in the same session by Frank Wattenberg and Klay Kruczek, both of whom I've worked with/learned from in the past.

TeX and friends get the StackOverflow treatment

Finding online support for programming has undergone a change over the years. Usenet forums allowed people to organize discussion threads in the pre-web days (now Usenet seems to be only used for file sharing). Email lists were and still are also used, but lack a filter--you have to receive all the questions and answers to be part of the discussion.

I just submitted my abstract for the 2011 Joint Mathematics Meetings to be held January 6–9 in New Orleans. I found a contributed paper session that was right up my alley: "Harnessing Mobile Communication Devices and Online Communication Tools for Mathematics Education."

Mashups for course websites with Yahoo! Pipes

Abstract: RSS stands for Really Simple Syndication or Rich Site Summary, depending on who you ask. Many websites publish a rich set of RSS feeds, which can be processed by other websites as a form of syndicated content. But the regular structure of RSS as an XML application means that feeds can be easily edited (``munged'') and combined (``mashed up''). Programming libraries exist for processing feeds, but Yahoo! Pipes makes this easy with a graphical user interface and no coding. We will discuss methods and applications of RSS feeds which might be suitable for a course website---for instance, combining feeds from SlideShare and scribd and publishing them to Facebook, or publishing your office hours on your blog automatically.

I'm also an editor for the MAA's Joint Mathematics Meeting Wiki, and one of the twitter evangelists who will be tweeting at #JointMath.

MathJax

I cashed in a lot of round tuits and updated the infrastructure on my site. One new addition is MathJax.

Pipify your life

Thursday, November 5, 2009 - 9:34am

Recently I discovered Yahoo! Pipes and I'm loving it. In case you haven't heard of it, Pipes is a construction kit for mashing up and publishing data. It gives you a funky GUI with different sources and operations becoming nodes in a network of flowing data. The final output is an XML feed, and Yahoo even provides tools called "Badges" to present that on web pages or otherwise process with JavaScript.

BYU students answer question "When will I use math?"

Via MAA News, a new website put out by math undergrads at BYU shows just what math is good for. Pretty, cool, and pretty cool.

Conference tweets broadcast beyond hotel ballroom

This is not a "Why I tweet" post nor is it a "What twitter is for" post. But it's a nice anecdote about how twitter works in interesting ways.

We've just wrapped up the 12th annual Legacy of R.L. Moore Conference in Austin, Texas. It's one of my favorite conferences and I decided to see if I could organize some collective twittering.

SlideShare now hosts documents

Wednesday, April 29, 2009 - 8:34am

I just found out that SlideShare allows you to upload portrait-oriented documents (like articles and handouts) as well as landscape (presentations). That's good for me, since I use SlideShare a lot for presentations but haven't been as good at sharing worksheets and their solutions. I've used scribd for that stuff but for whatever reason I haven't been as diligent at uploading. One-stop shopping will help.

Here's an embed of a SlideShare-hosted worksheet:
