MP3 Podcast of my talk at Emerging Telephony on how to love CALEA

Last week I spoke at O'Reilly's Emerging Telephony (ETEL) conference about CALEA and other telecom regulations that are coming to VoIP. CALEA is a law requiring telecom equipment to have digital wiretap hooks, so police (with a warrant, in theory) can come and request a user's audio streams. It's their attempt to bring alligator clips into the digital world.

Panoptopia and the Pushbutton Panopticon

With too many people defending the new levels of surveillance, I thought I would introduce a new word: Panoptopia -- a world made wonderful by having so much surveillance that we can catch all the bad guys.

David Brin introduced the concept to many in The Transparent Society, though he doesn't claim it's a utopia, just better than the alternative as he sees it.

It used to be that "If you are innocent you have nothing to hide" was supposed to be a statement whose irony was obvious to all. Today, I see people saying it seriously.

What's the default on 4th amendment questions?

We're always coming up with new technologies that affect privacy and surveillance. We've seen court cases over infrared heat detectors seeing people move inside a house. We've seen parabolic microphones and lasers that can measure the vibration of the windows from the sound in a room. We've seen massive computers that can scan a billion emails in a short time, and estimates of speech recognition tools that can listen to millions of phone calls.

Scroogle -- Scrabble played with Google

Here's an idea to try -- Scrabble played with Google as the base, rather than the dictionary. Ie. you can play any word you can find in Google (sort of.)

This obviously vastly expands the set of words, perhaps too vastly, and it brings in all foreign languages to boot. It includes vast numbers of joinedwords, and zillions of other things. As such you would want to consider the following limits:

Google Subpoena is the tip of the iceberg

Google is currently fighting a subpoena from the DoJ for their search logs. The DoJ experts in the COPA online porn case want to mine Google's logs, not for anybody's data in particular, but because they are such a great repository of statistics on internet activity. Google is fighting hard as they should. Apparently several Google competitors caved in.

Wanted -- a system to anonymously test the support of radical ideas

How often does it happen? There's an important idea or action which is controversial. The bravest come out in support of it early, but others are wary. Will support for this idea hurt them in other circles? Is the idea against the "party line" of some group they belong to, even though a sizeable number of the group actually support it? How can you tell.

On the two-tier internet

Of late there's been talk of ISPs somehow "charging" media-over-IP providers (such as Google video) for access to "their" pipes. This is hard to make sense of, since when I download a video from a site, I am doing it over my pipe, which I have bought from my ISP, subject to the contract that I have with it. Google is sending the data over their pipe, which they bought to connect to the central peering points and to my ISP. However, companies like BellSouth, afraid that voice and video will be delivered to their customers in competition with their own offerings, want to do something to stop it.

To get around rules about content neutrality on the network that ILEC based ISPs are subject to, they now propose this as a QOS issue. That there will be two tiers, one fast enough for premium video, and one not fast enough.

Today I've seen comments from Jeff Pulver and Ed Felten on possible consequences of such efforts. However, I think both directions miss something... (read on)

Curses on you, bluetooth

Well, I am going to get a bluetooth cell phone shortly and so I got a headset and dongle to use on my laptop, where I also make VoIP calls.

I was shocked, flabbergasted to find that the bluetooth headset profile only transmits audio at telephone quality 8khz sampling rate. So even plugged into my laptop for hifi (didn't think I
would ever need to use that term again) recording, it sounds like a telephone, and likewise for
playback.

Why? Why? Why?

Reinventing the phone call -- demos for team members for re-startup this week

This week I will be doing some demos of Voxable, my system that combines VoIP, presence and all sorts of cool stuff I won't be writing about in the public blog to create a new user interface for the phone that is both as modern and internet as it can get while also being a reflection of the ancient interface for the phone that was lost.

Demand junk mail by PDF

Who could possibly imagine wanting spam? Well, I just read that in the USA, 100 million trees are felled every year for junk mail. 28 billion gallons of water used to process the paper. And 350 million dollars spent to throw it out. That doesn't include I presume the other costs, including postage and wasted time, this is just the paper part of it.

Student annotated video of lectures

Today many universities are doing video of their lectures, and making it available on the campus LAN (or older campus cable TV.) In some cases students are not going to class, but many just find it a useful addition.

I suggest an application where students, while watching the lecture, could press keys on their computer synced in timestamp with the video. They don't need to be online, they just need a modestly good clock. Buttons like "This is important, review this for the final." Or even comments like "I already know this" and "I'm lost."
