Analemma

This one's for Alonso, who's studying heirophanies (love that word) in Palenque. It's a photo of an analemma, the shape traced by the path of the sun, at the same time each day, over the course of a year.

George Fisher, Cartoonist who fought dams

This is far from the Usumacinta, but an opponent of dams died this week. He was George Fisher, a political cartoonist in Arkansas who frequently lampooned the Army Corps of Engineers and other builders of dams.

First, two appreciations of the man:

Usumacinta, Realidad Amenazada

Fastline - Mesh ISP in Texas

Vivian goes high speed, wireless

"Kenny Bain said he was prompted to start Fastline due to his frustrations over the unresponsiveness of CMA and CenturyTel - the local telephone provider - to requests for high-speed access in Vivian."

I can relate. No DSL for me, because Verizon skimped in this neighborhood by using a "DAML" to split phone lines, making them useless for high-speed internet.

U.S. Mesh AP distributor

Usumacinta Delta

So far we have concentrated on the Usumacinta upstream from Boca del Cerro. Below the proposed dam site is one of the most important wetlands in the region.

Terrestrial Ecoregions -- Usumacinta mangroves (NT1437)

Long-term threats to the region include overexploitation of resources, continuous industrial pollution of the waters due to human overpopulation, oil extraction, and the possible construction of building a hydroelectric plant that would impact a large part of the aquatic habitat. According to IUCN (Scott & Carbonell 1986), the Gulf Coast contains the largest area of wetlands in North America.

Mesoweb - Maler and the Usumacinta

I looked at this several years ago but now have a little more experience on the river to bring to it. Teobert Maler was one of the giants of Maya exploration and photography. Joel Skidmore, creator of Mesoweb, has given us the best introduction to Maler's work and travels.

Thanks to Jose Yunis at NRDC who brought this document to my attention. On this page is a link to a pdf entitled "Programa de obras e inversiones del sector eléctrico 2002-2011". Note: it is over 100 pages long and may take some time to download on a slow connection. The Boca del Cerro dam is referred to in several places, confirming that it is still being studied.

WiFi Anywhere: The Pocket Router

(via Daily Wireless and Mobitopia)

Using an iPaq handheld as a wireless access point, and a cell phone as the internet link. Connect the two with Bluetooth.

This should work with a Mac laptop that's equipped with bluetooth instead of the iPaq. And it would save running linux AP software - that part is built-in to the OS. But not having a bluetooth-equipped GPRS cell phone, I can't try it out.

Usu presser, one year later

A year ago, Chris Shaw, Alonso Mendez, Moises Morales and I joined Homero and Betty Aridjis in Mexico City. At a press conference, we announced a letter opposing dams on the Usumacinta River, which we then delivered to President Vicente Fox. Well, we dropped it off at Los Pinos, the Mexican White House. Got a signed receipt. Had lunch.

The letter was published in full the next day in Reforma. I believe it played a small part in the shelving of the dam plan, although feasibility studies, and our opposition, continue.

Here's a short note in German, from der Standard, a year ago. Missed it then. Glad the word got around.

It enables secure identification of users
It allows you to create a "splash page" that automatically pops up
It makes shared wireless Internet services practical.

Cable Modem Problems

Yep, you don't learn about stuff until it breaks. And I've been in cable modem hell since Thanksgiving. I know a lot more about DHCP by now but it's still not connecting properly. The advice below seems to cover everything I've done so far. But I'm still looking for an answer. Could it be Time Warner's fault? I'll have to wait 4 more days for the fourth visit from a tech guy to find out.
