I’ve used tc in the past, and it’s loosely related to something else I’m currently reviewing, but not tied directly enough that it’s something I want to delve deeply into at the moment.  The quick takeaway is, if you are trying to emulate the characteristics of a network connection within a lab, this (probably) is the tool you’re looking for.

Google Voice: a cheapskates guide to cheap VOIP | ZDNet

I’ve been thinking I need to add a “local” number at home for some time, but I hate to ditch the Google Voice number I’ve had for some time (and do have a few services associated with).  I recently noted that GV has an option to select a new number and permanently retain your existing GV # for just a $20 administrative fee… may seriously look into doing so.

I ran across this article while investigating a bug-that-was-not-a-bug-but-proper-behavior.  I’d see the SRV records before when looking at Microsoft DNS for Active Directory, but didn’t know the details about what it was or how it was used.  Great summary article.

Handy reference covering some of the commands for configuring Microcore, and practical examples of how to make the configuration changes persistent across reboots.  Used as a reference (one of many) in configuring an OpenSSL CA and FreeRADIUS server for an  EAP-TLS wireless test environment

I think these could be really useful and are reasonably priced.  Sure, 10BT, but that’s plenty of bandwidth for a number of low volume devices.

IPv6 – Charter

Yet another tab that I need to make a note of and come back to at some point.  Interested to see how my Asus router with Tomato firmware does with IPv6, and to start spending some time getting familiar with the “new” protocol.
