Since there are usually a large number of distinct single items in a typical
transaction database, and their combinations may form a very huge number
of itemsets, it is challenging to develop scalable methods for mining frequent
itemsets in a large transaction database.

Apriori algorithm - Wikipedia, the free encyclopedia

Apriori algorithm - Wikipedia, the free encyclopedia: "In computer science and data mining, Apriori[1] is a classic algorithm for learning association rules. Apriori is designed to operate on databases containing transactions (for example, collections of items bought by customers, or details of a website frequentation). Other algorithms are designed for finding association rules in data having no transactions (Winepi and Minepi), or having no timestamps (DNA sequencing)."

How to setup SSL on Amazon EC2? - Server Fault

How to setup SSL on Amazon EC2? - Server Fault: "In your EC2 control panel, look at your instance and note the Security Group that is assigned to it. Then, navigate to the Security Groups section in the control panel, open your group, and make sure that port 443 is allowed over TCP.

This must be open to allow SSL traffic to your instance. A simple way to check if the port is open to the outside is to telnet into your server's IP on port 443, and see if you can connect and get a response.

telnet yourhost.com 443"

Bret Victor, beast of burden

Bret Victor, beast of burden:

I believe that dynamic pictures will someday be the primary medium for visual art and visual explanations. The medium is currently in its infancy -- working in the medium is more about technological fumbling than artistic expression. The revolution cannot happen until there is a means for artists to draw dynamic pictures.

This essay describes what dynamic pictures are, what dynamic drawing is, why the subject is so important, and some initial project ideas.

If any of this inspires you to play around with these concepts, I'd love to see what you come up with.
