NOE on DVD

Breaking News: The Nature of Existence is now available on DVD. In fact, there is an affordable two-disc set available that has 80 minutes of additional material (which possibly includes more footage of Roger's interview with me), and a seven-disc companion set that does what I had hoped for (and asked for in my review of the film in The Skeptical Inquirer): explore all the questions that the

Essentials in Politics

I have added a new section to my Richard Carrier Recommends Amazon storefront. For those who might not remember (see earlier blog about this) my Amazon Storefront is a place where you can buy books from Amazon and I get a cut of Amazon's profits. It's a nice way to help support me, and get some great books that have been influential on me, and that I think are essential reading these days. I

Reliable transport vs. reliable transport

One of the most contradictory uses of terminology in communications concerns the word transport as used by the IETF and the ITU-T communities.

IETF79 - Beijing !

OAM for flows

Continuing my coverage of the recent joint IESG/IAB design team on OAM, this time I want to discuss the issue of OAM for flows in Packet Switched Networks (PSNs).From a pure topology standpoint any communications network is imply a set of source ports (i.e., interfaces into which we may input information), a set of destination ports (i.e., interfaces from which we may receive information), and a

IETF and OAM

On October 12nd and 13th the IESG (Internet Engineering Steering Group) and IAB (Internet Architecture Board), the two IETF management bodies, held a joint design session on OAM. I was a bit surprised that the IETF leadership would be interested in devoting a separate meeting (not coinciding with an IETF conference) to the subject of OAM; OAM has never been an area of IETF expertise. Indeed, when

Skepticon Selling Out

Just a quick heads up: Skepticon 3 is on the verge of selling out. Only a few hundred seats left (out of some 1500 or so). So if you want in, now's the time...
