Lawrence Lessig's LinuxWorld talk online

LinuxWorld has put up a video of Lawrence Lessig's LinuxWorld keynote. It is in Flash format, however, and thus not accessible to all Linux users.

I have a copy of a higher-res version of the video on its way to me, and will transcode to Ogg Theora and put it up.

Thanks (in advance ;-)

Lawrence Lessig's LinuxWorld talk soon to be online for free software

Thanks Don.

Would that this were the norm for promotions of free culture.

That would be wonderful. I'd love to show this at my LUG's meeting this month. THANKS!

Ogg Theora version up

Now linked. This version looks great compared to the streaming one.

Arg. LinuxWorld --- could you provide a link to a free format (mpeg or theora) version of this video? Ironic that a presentation about Free Culture would be in a non-free container...

Heh. You beat me to it, Don. Looking forward to the Theora version. Thank you!

a clean, clear cut presentation of our past, current, and future culture
through the Internet by using the network OSI layer model. The clear and
present danger of the ruling elite killing the rise of RW culture is
convincingly presented by the possible control or even killoff of the
physical layer. But no worries, even for this problem called "network
neutrality" Lessig encourages and promotes the private initiative to
implement Wireless Network for the last mile Internet access.

I have only one suggestion to add : Why should we use electronic waves
for these purposes which are inside the Microwave band? Is it not so that
especially the Microwave band was not used by the military, industry and
government (i.e. Military Industrial Complex) because it could possibly
harm human beings and tissue, and as such has never been used or claimed
inside a FCC frequency regulation? The microwave bands have never been in
use before, except of course through the use of contained microwave
ovens. As the microwave band has always been left unused, the launch of
popular frequencies like GSM, UMTS, WiFi make me wonder why never a word
of concern has been raised. The conspiracy theories about why, i don't
want to even talk about.

So if you want to build a Wireless Internet, first start claiming a
frequency band which won't harm human beings, animals and nature.

`Microwave' usually refers to any frequency between 1GHz and 300GHz. A microwave oven operates at around 2.45 GHz, which is the resonant frequency of a water molecule, ie. the frequency which it absorbs most strongly (causing it to heat up). Frequencies other than 2.45 Ghz are much less harmful to water-containing organisms like us. Much of the microwave range has been allocated for years. I'm not saying it's nothing to worry about, just that the most harm is caused by a very specific frequency out of a very wide range.

2.45 GHz eh?

from http://en.wikipedia.org/wiki/Wi-Fi :

"The frequencies for 802.11 b/g span 2.400 GHz to 2.487 GHz. Each channel
is 22 MHz wide and 5 MHz spacers between the channels are required. With
the required spacers, only 3 channels (1,6, and 11) can be used
simultaneously without interference."

from
http://en.wikipedia.org/wiki/Universal_Mobile_Telecommuni... :

"The specific frequency bands originally defined by the UMTS standard are
1885-2025 MHz for uplink and 2110-2200 MHz for downlink."

That's not far of from the microwave resonance frequency of H2O eh?
Selecting a safe frequency range for mobile or wireless communication is
not a issue, its just a matter of misty politics. As long this matter is
not clearly solved, GSM, UMTS and WiFi will just stay wikipedia words for
me.

Yeah, that's pretty close to 2.45 GHz alright. Obviously I should have checked more carefully before posting a reply. It turns out that the quick google I did for `microwave oven frequency' produced some misleading info.
The microwave absorption spectrum of H2O is actually very complicated. It apparently doesn't resonate at 2.45 GHz after all, but it does heat up effectively at that frequency (hence the choice of 2.45 GHz for microwave ovens) and others. That's actually worse - a wide range of microwave frequencies is likely to cause water to heat up.

I'd feel smug because I don't use wireless, except we're all surrounded by this stuff a lot of the time. Where'd I put that tin foil suit?

Sometimes it is sad not all visionaries are as stubborn as Stallman. He
probably wouldn't stand for distributing his presentations non-free,
rendering it inaccessible for a majority of Linux users.
