Inside the Fold: the Mathematics of Origami.

Folding paper cranes or fancy boxes may seem like a quaint and old-fashioned hobby. But paper folding, or origami as it's more properly called, is serious science. Everything, from the proper loading of the space shuttle's cargo bay to the best use of materials to make cars, can be improved if we understand how to fold things up. Not to mention the problem of how to get that map refolded and back into the glove compartment. At the forefront of this field of computational origami is Canadian scientist Dr. Erik Demaine, who recently became one of the youngest people to ever win a MacArthur award - known as the genius prize. (Via CBC Radio's Quirks & Quarks).

Some interesting stuff on the young Doctor's page, I'm going to stress my poor brain out try to comperhend.

Beyond the Beyond is his new bloging home after retiring his old SchismMatrix (one word or two?) blog.


David Langford's The Runcible Ansible is still alive next door... Where I learned of Hard SciFi author Hal Clement's (Harry Clement Stubbs, 1922-2003) passing. (famous for his most excelent "Mission of Gravity". Thanks Hal! )

If you're a fan of BoingBoing, perhaps you've noticed the site's been MIA for the past few days. There have been some hosting 'issues' and BoingBoing is now in the process of moving to a new host. In the meantime, you can access the site at http://216.126.84.59/. Xeni says that, ''BoingBoing.net' will work again in a day or two.'"

What Is Lotus Notes?

What Is Lotus Notes?


What is Notes -- the Manager version

Lotus Notes is an application suite that includes the following components:

* e-mail
* calendaring and scheduling
* address book
* database
* web server
* programming

Unlike other application suites (like Microsoft Office) that split these pieces of functionality into separate products (like Outlook, Access, Front Page, etc.), Lotus Notes presents all of these components using a single front-end.

A Plan for Ham, Company News Done Right.

InfoWorld TechWatch: Taking RSS for granted suggests using RSS News Reader as a cheaper alternate to expensive news clipping services, combined with Blog postings.

I've been thinking of this as a possible solution for sometime, although I doubt it could remove the need to have a company news editor to build the daily news summary. Posted the resulting items to a Blog (with-in a company intranet portal or not) is a win-win on a couple of fronts : less emails in the in-box; older items are available to everyone (including the new hire) ; less clutter in email folders as people no longer have to guess which one might be important to them.

High Quality RSS news feeds are the biggest fly-in-the-ointment : does the description tag content the full text, and if not, could the text be retrieve auto-Magically from the link url (given the state of html this is hard),

Keyword filtering of incoming RSS items might help but a trained Bayesian approach, the reverse of a Spam Filter (see Paul Graham's 'A Plan for Spam', in this case a Ham Catcher , would aid finding relevant articles.
