One of the risks of following bright folks like Lilia is that you end up with all sorts of interesting and intriguing things for your reading list.

HP: How to search a social network, Finding Communities in Linear Time. Implicit Structure and the Dynamics of Blogspace and more papers from HP Information Dynamics Lab.

It's always like that: looking for one thing you find many others.

Where was grade inflation when I was in school?

Another Form of Grade Inflation.

You may recall Princeton's proposal to fight grade inflation by putting a quota on the number of A's that can be awarded. Joe Barillari made a brilliant followup proposal in yesterday's Daily Princetonian, to fight the "problem" of inflation in students' ratings of their professors' teaching.

Isn't this the truth. And a truth that I, too, need to learn over and over again. Now, I have a handy reminder.

You can't rush readiness.

Homeschooling parent, Sarah, reminds of a very important point when it comes to parenting:

You can’t play games with readiness. That’s been my one of my Most Important Parenting Lessons (and one which I, apparently, need to learn over and over again). Kids are, or are not, ready.

...

Readiness simply comes of its own accord. You can lay the foundation, but no game, no trick, no bribe can make an unready child ready. Those things are approaches or motivators; they don’t flip the switch inside their brain, or body, or heart. They’ll be ready when they’re ready. And because we’re impatient, or we believe we know better, or that we’re more powerful/ influential than we are, we struggle to learn this lesson. But go ahead and learn it. You’re ready.

Something to add to my Radio setup here. Matt Mower up to his usual tricks. Thanks Matt and thanks Lilia for passing this along.

Technorati macro for Radio.

For Thomas and others: Radio macro to get Technorati cosmos for a post (see this post in browser for an example).

From Matt Mower via IM:

• save http://matt.blogs.it/gems/postCosmos.txt into your Macros folder
• edit #itemTemplate.txt adding <%postCosmos( <%itemNum%> )%>
• publish

I also edited macro to display "Technorati cosmos" instead of "What other blogs are saying about this post", you'll find it easily in the text.

Innovation continues. I have both the Kensington unit and the WFS-1, which I prefer of those two. This looks to be a definite improvement over the first generation products.

World's greatest Wi-Fi signal finder. Glenn Fleishman got his hands on a prototype of a new, tiny, Wi-Fi signal finder, and he likes it a lot. There's a video clip of it on his site.

Chrysalis previews their WiFi Seeker, a keychain sized device for instant Wi-Fi signal finding: Chrysalis sent me a demo unit of its just-unveiled WiFi Seeker, which they designed to differentiate 80211b/g networks from other devices. Two previous Wi-Fi signal finders fell short in ways the Seeker does not.
