Joi Ito's Web

Joi Ito's conversation with the living web.

I love that the "tone" of phrack articles is the same as Cook's Illustrated articles. ;-)

A more environmentally friendly way of traveling by car. As some of you might recall in almost all the hacking movies, books, TV shows, etc. there has been a case of someone fiddling with traffic lights. Well we all just giggled at the unrealistic aspect of it and didn't think twice. Well in my quest for a more appealing planet for our children I felt compelled to think of a way in order to reduce the amount of pollution emitted by vehicles of today.

Standing at a intersection, nobody else around, you're still stuck behind the red light, and this invisible barrier of governmental guilt has enough power to let you wait there and pollute the air more and more, just for a measly green light. Wouldn't it be leet having a laptop in the car where you could just select the intersection off a list, change the timing or current stream running, and ride off with fewer time wasted and fewer pollutants exhausted and a clear conscience.

Now, enough crap about the reasons, now for the technical shit.

Today's traffic controlling system is a well oiled redundant network that utilizes the same protocols that we are all aware of. Yes it is hackable and it is like in the movies. :) here we go!

We're going to have an open moblog for people to post pictures to on New Year's Eve to welcome 2003. It is "open" but please use common sense when sending stuff. The URL is The email address to send stuff to is The site and the email address will be running between GMT 2002/12/31 0:00-23:59.

Send jpeg images as attachments with the title of the item as the subject. The template will resize the height to 120 pixels. 120x120 is probably the best size.

Pass it on. ;-)

"Misoka" comes from "Omisoka" which means New Year's Eve in Japanese

This may not help Sadaam, but just in case you're put under GPS surveillance house arrest by an oppressive government, you'll need to learn how to build your own GPS jammer.

  A low cost device to temporarily disable the reception of the civilian
course acquisition (C/A) code used for the standard positioning service
(SPS)[1] on the Global Positioning System (GPS/NAVSTAR) L1 frequency of
1575.42 MHz.

This is accomplished by transmitting a narrowband Gaussian noise signal,
with a deviation of +/- 1.023 MHz, on the L1 GPS frequency itself. This
technique is a little more complicated than a simple continuous wave (CW)
jammer, but tends to be more effective (i.e. harder to filter) against
spread spectrum based radio receivers.

Doc Searls writes about an article in the Santa Barbara News-Press about UCSB history professor Tsuyoshi Hasegawa and his theory. The newspaper says:
Santa Barbara News-Press
The historical record holds that Japan surrendered in response to the bombing of Hiroshima and Nagasaki by the United States. Revisionists argue that the Japanese were already defeated at the time, and the atomic bombs were used simply to intimidate the Soviet Union.

Mr. Hasegawa dismisses both views as "very, very American-centric."
It was Josef Stalin's final-hour declaration of war on Japan that marked the end of the conflict in the Pacific, according to Mr. Hasegawa, whose specialties include Russian and Soviet history as well as Russo-Japanese relations.

Obviously, this is very relevant to the current "War-on-Terror" and is an important part of Japanese history. Japan is still struggling with Russia over the islands that the Russians claimed as theirs after the war...
