webfinger - Project Hosting on Google Code
** Posted using Viigo: Mobile RSS, Sports, Current Events and more **
Back in the day you could, given somebody's UNIX account (email address), type finger email@example.com and get some information about that person, whatever they wanted to share: perhaps their office location, phone number, URL, current activities, etc. The finger protocol, sadly, died. Fast-forward to Web 2.0. We're currently bickering about how we do interop between all these social web services, and even how we represent a person's identity. The two main identity identifier camps are email addresses and URLs.
Google Code Project Page for "WebFinger" protocol
We're bringing back the finger protocol, but using HTTP this time.
from here, it should be downhill to world-wide, usable identity
WebFinger is about making email addresses more valuable, by letting people attach public metadata to themFinally: Finger Trees! : Good Math, Bad Math
What finger trees do is give me a way of representing a list that has both the convenience of the traditional cons list, and the search efficiency of the array based method. The basic idea of the finger tree is amazingly simple. It's a balanced tree where you store all of the data in the leaves. The internal nodes are just a structure on which you can hang annotations, which you can use for optimizing search operations on the tree.
"The basic idea of the finger tree is amazingly simple. It's a balanced tree where you store all of the data in the leaves. The internal nodes are just a structure on which you can hang annotations, which you can use for optimizing search operations on the tree. What makes the finger tree so elegant is the way that some very smart people have generalized the idea of annotations to make finger trees into a single, easily customizable structure that's useful for so many different purposes: you customize the annotations that you're going to store in the internal nodes according to the main use of your tree." A commentator says regarding the article however, "Ørjan Johanse is right. You described a monoid-annotated-binary-tree, which is not enough to be a finger tree."http://www.magnetnerd.com/Neodymium%20Magnets/Dirks%20Accident.htm
Dirk had an accident. Below is the X-ray showing his totally crushed finger tip. It took 1 1/2 hours of surgery to remove the shattered bones and repair the damage. Medically speaking, he crushed his right index finger distal phalange. The magnets had a 50 cm (20 inch) separation when they decided to fly together.
includes gory finger photos...
accidente con imanes de neodimio. muy explícito :-(
