Ok, I know I’m too much of a geek for my own good, but this open course about Problem Solving on Large Scale Clusters looked pretty interesting, until I saw the description for Lab 3, at which point it became too interesting:
Lab 3. The Goal — Implement PageRank, turn Wikipedia into a giant graph, run PageRank on said graph, run it several more times (ideally until the values converge), return (in a humanly parseable sort of way) the PageRank of all the articles.
Finally - an open computer science course I’m really going to work through!

A rare Sunday post for me. Today in the semi-annual LDS General Conference, Elder Oaks quoted research from a recent study at Columbia’s National Center on Addiction and Substance Abuse about the relationship between teens’ academic achievement and how frequently they eat dinner with their family. BusinessWeek summarized the findings as follows:
Their research has found that children who have a regular family mealtime are less likely to smoke, drink, use illegal drugs, experiment with sex at a young age, and get into fights. Further, these children are at lower risk for suicidal thoughts and are more likely to do better in school. Teens that have frequent family dinners are more likely to be emotionally content, to work harder, to have positive peer relationships, and to have healthier eating habits. Family mealtime is the single strongest predictor of academic achievement scores and low rates of behavioral problems, regardless of race, gender, education, age of parents, income, or family size.
I just want to highlight the last sentence there - Family mealtime is the single strongest predictor of academic achievement scores and low rates of behavioral problems, regardless of race, gender, education, age of parents, income, or family size. The study compares teens who eat dinner with their family five or more times per week with those who eat dinner with their families two times or fewer per week. You can complain about traditional family values all you want, but there’s something here.

Logan’s newspaper, The Herald Journal, has been doing top 10 lists this summer. On September 8 HJ writer Kim Burgess did a back-to-school top 10 list of “Classes Every Aggie Should Take,” and I was pleasantly surprised to see my “Blogs, Wikis, and New Media for Learning” on the list. She says:
Everyone and his dog has a blog these days. Making yours stand out takes a bit more work…. This course goes over a variety of “web 2.0” technologies including blogs, RSS, wikis, social bookmarking tools, photo sharing tools, mapping tools, audio and video podcasts, and screencasts. You’ll be a YouTube pro by the end of the semester.

Twice in the last week I’ve heard the phrase “free knowledge.” I understand that there are many people with more influence in the world than I who like this term (e.g., Jimmy Wales’s “Free Knowledge requires Free Software and Free File Formats“). In fact, I heard Jimmy use this phrase last week at the Shuttleworth/Soros/Hewlett-sponsored meeting in Cape Town. He was describing why he doesn’t like the term “content.” Because “content,” he said, sounds like a static something that can be packaged and shipped. And so he prefers the more living, breathing, dynamic term “knowledge,” which he uses to characterize sites like Wikipeida. Now, fully understanding that many of you could care less, I have to get this off my chest anyway… Continue reading ‘There’s No Such Thing as Free Knowledge’

A fun service over at http://www.careerdistinction.com/ measures your “online identity” on a scale of 1 to 10. I did pretty well:
Your online identity score is 10 out of a possible score of 10. Congratulations. You are digitally distinct. This is the nirvana of online identity. Keep up the good work, and remember that your Google results can change as fast as the weather in New England.
It was pretty crazy to see that in a Google search for “David Wiley” 25 of the first 30 results were about me (i.e. there were only five results about some other David Wiley in the first three pages of Google results). What does this mean at the end of the day? I’m not sure… but my wife will have to work extra hard to help me get my already oversized head through the doorway for a while. :p
