CMS by Drupal
From this Negroponte email:
Sugar is a very good idea, less than perfectly executed. I attribute our weakness to unrealistic development goals and practices. Our mission has never changed. It has been to bring connected laptops for learning to children in the poorest and most remote locations of the world. Our mission has never been to advocate the perfect learning model or pure Open Source. I believe the best educational tool is constructionism and the best software development method is Open Source. In some cases those are best achieved like the Trojan Horse, versus direct confrontation or isolating ourselves with perfection. Remember the expression: perfection is the enemy of good. We need to reach the most children possible and leverage them as the agents of change. It makes no sense for us to search for the perfect learning model.
I have no comment here—I'd be interested to hear what others think of this paragraph, though.
I am trying out Twitter again, although I'm pretty skeptical. You should be able to see my latest Twitters again somewhere to your left, I think.
To be honest, this post is mostly a test of the Drupal Twitter stuff. I'll report more after I've had some experience with it.
I keep wanting to blog about my latest tiny piece of software, but I keep having one more bug or feature.
So instead, I've cooked up this little word game. Tell me what you think of it…
I was playing in a D&D game with my boy last Sunday, and someone brought up the question of how likely a character was to have an 18 stat. Of course the rest of the session was a loss for me, as I sat there trying to do the math with pencil, paper, and a four-function calculator.
D&D has six stats, each a number between 3 and 18. The character roll-up rules we are playing specify that each stat will be obtained by rolling four dice and taking the top three.
About 9% of D&D characters will have an 18 stat. The answer is explained here.
So I thought about it tonight and figured out that in Haskell I can generate the Fibonacci sequence using the definition
If you type this at ghci you can say "take 20 l" and get
Laziness weirds programming.
From this interesting blog post:
Which is sadly all too often true. I'm definitely one of the ones who will tend not to find the much happier
In a previous blog post I talked about some serious problems I had with questions on a standardized math test my son took recently. Apparently Reddit linked it, and both my blog and Reddit got a number of comments.
The interesting thing to me is the documentation the whole incident brought to the existence of two dramatically distinct views of what mathematics is—something I'd go as far as to call a mathematics "class divide"…
It seems like I've been posting a lot of negative stuff lately. I'm a naturally cranky, opinionated person, but there's lots of things I enjoy. I should report on them too.
I recently reviewed the worst juvie novel I've ever read—the "banned book" The Transall Saga. Today I have the happier task of reviewing a well-written and intriguing novel intended for a slightly younger age group. Gordon Korman's Swindle came to my attention today when my son brought it home from the school Book Fair, where apparently every kid in school bought a copy. I'm always suspicious of these sudden hits, but I read a couple of chapters of Swindle this morning.
