Wired has an article on the four major record labels abandoning DRM and turning to watermarking, so it seems.

There is also reference to a patent disclosing an audio watermarking scheme dubbed 'El Dorado' assigned to Microsoft. Inventors: D. Kirovski & H. Malvar. "What is claimed is: 1. A method for encoding values within a digital audio signal, the method comprising: receiving the digital audio signal having frequency magnitude components; analyzing the relative energy levels of the frequency magnitude components of the signal; determining whether the signal has a large discrepancy in the relative energy levels of the frequency magnitude components, wherein the large discrepancy is a discrepancy of a factor of three or more; encoding at least one bit of the digital watermark into the digital signal based on the determination."

IP over DNS - iodine on OpenWRT

"iodine lets you tunnel IPv4 data through a DNS server. This can be usable in different situations where internet access is firewalled, but DNS queries are allowed." Applies to many public hotspots...

Sounds useful, I tried to set it up using free subdomain (FreeDNS) and DNS (xname) service, with iodine running on my Asus wl500gp OpenWRT router (with dynamic IP (DynDNS)).

24C3 - Chaos Communication Congress 2007

I've been to Berlin for the 24C3 (Dec. 27 - 30, 2007). Lots of interesting talks and great fun!

My work on Sputnik analysis got cited by Tomasz Rybak's work.
Got to analyze the new and hopefully correct data now :)
And buy some more RFID stuff: OpenPICC, OpenBeacon USB node.

Here's a list of the most noteworthy (technical) talks from Fahrplan:
