DARPA brings Web 2.0 prowess to the battlefield

tigr

An interesting interview about TIGR, a recently deployed DARPA project in Afghanistan and Iraq. With a timeliness which is impressive for its contemporary awareness, TIGR integrates many layers of data (satellite photos, census data, road conditions) with metadata generated by military patrols (attack reports, experience with certain houses, etc). In this way, knowledge that is lost when units cycle out of a certain districts is able to be transferred to their replacements. The interview gives a sense of the development process, infrastructure and the uses of the system. I wonder if this sort of thing will be deployed in domestic law enforcement. In any event, it is interesting to observe how the widespread fervor and innovation of Web 2.0 technologies in the civilian realm prefigure military applications — almost a reverse dual use to the things.  [link]

The ephemeral sights of shortwave radio

Shortwave radio must have been an extraordinary technology to really have been in the capture of. You order plans, build a ham radio, and suddenly, as if you have been imbued with some occult power, you become aware of these stratosphere-bouncing conversations that encircle the globe. This when there was much more of a global expanse to imagine — distant, exotic lands and all of the like.

These QSL cards a really quite beautiful — they seek to give visual form through one, light-stock, piece of card board: a terrestrial marker of an ethereal enterprise. To wit,

QSL cards (or letters) are exchanged to acknowledge ham radio contact between stations. Broadcast stations (mediumwave and shortwave) also offer colorful QSL cards to listeners who send in reports of reception. These souvenirs of the radio listening hobby (or “DX’ing,” as it’s sometimes called) are slowly vanishing as the radio hobbies shrink. Nowadays hams often “QSL” contacts via the internet, bypassing the cost and postage of physical QSL cards. Many international shortwave broadcasters have either drastically cut back services or closed down altogether as their target audience migrates to the internet and satellite radio. Thus, most of these QSL cards are echoes of stations long gone, and a knob-twiddling pasttime whose glory days have passed. [link]

A sampling of the post-war visual culture of tech

An assortment of science and technology ads from the 1950s and 60s has been collected on this flickr page. Many of the modernist illustrations used by the ad agencies are quite fantastic. I suppose that thoughts of intercontinental ballistic missiles, vacuum tubes, thin ties and cigarettes lend themselves to this sort of thing:
