Recording Skype Calls - Sat, 27 Dec 2008 20:25:00 +0000

Here are the basic settings that I used on a Mac to record Skype conversations using SoundFlower, Skype, and Audacity. SoundFlower Default Input:SoundFlower (2ch) Default Output:Built-in Output Skype Audio output:SoundFlower (2ch) Audio input:SoundFlower (2ch)(if you wan't to record both sides of the Skype call) Built-in Microphone(if you only wish to record the other side of the conversation) Audacity Recording Device:SoundFlower (2ch) Playback Device:Core Audio: Built-in Output You could record many other things using similar configurations. Happy Recording!

Network Roles - Tue, 16 Dec 2008 20:35:00 +0000

Social networks tend to have people that fill positions within the community. For example, within an academic community the roles of being a professor or a student can sometimes be identified solely by using the directed interactions among the individuals. To perform such an analysis, some measure of equivalence is used. In Social Network Analysis by Wasserman and Fauts, the following definitions of equivalence are reviewed (each with a note): Structural Equivalence- requiresidenticalties to otheridenticalactors Automorphic and Isomorphic Equivalence- requires identical ties to other actors Regular Equivalence- actors have identical ties to and fromequivalentactors Local Role Equivalence- actors are role equivalent if they have the same role sets Ego Algebra Equivalence- based on algebra of relational structuresSo, why is knowing how to use this important? Well, say you would like to better understand the network surrounding your blog by learning which other blogs are similar in their ties as you, then this is how you could do it.

Blog Posts Increasing and Cyclic - Sat, 29 Nov 2008 01:21:00 +0000

During the span of a year, the over 200 blogs aggregated above show very cyclic behavior. It shows very prominently that these bloggers post significantly more posts during the week rather than on the weekends. Additionally, as time went on, these blogs as a group posted more frequently. I would guess that the sink during December was caused by the Christmas holiday.
