Digging Blackhawk Slide
One day, back around 15,000 BCE, half a mountain in Southern California broke loose and slid out onto what’s now the Mojave desert. The resulting landform is called the Blackhawk Slide. Here it is: It’s that ripple-covered lobe on the bottom right. According to Robert Sharp’s Geology Underfoot in Southern California, it didn’t just flow… Continue reading

Catching up
Some links and thoughts on a Saturday night… The Matrix is still my favorite movie of all time. I explained why here in Linux Journal, back in 2006. Spoke to the Chief of Naval Operations Strategic Studies Group, of the U.S. Naval War College earlier this week, in Southbridge, Mass. The session was three hours… Continue reading

The biggest picture
I want to plug something I am very much looking forward to, and encourage you strongly to attend. It’s called The Overview Effect, and it’s the premiere of a film by that title. Here are the details: Friday, December 7, 2012 – 5:30pm – 7:00pm Askwith Lecture Hall Longfellow Hall 13 Appian Way Harvard University Cambridge, MA The world-premiere… Continue reading

The kontroversial kittehs of Rome
Strays Amid Rome Set Off a Culture Clash says The New York Times. On one side, archaeologists who wish to save ruins from occupation by cats. On the other side, the cats’ lovers, including tourists who marvel more at the abundance of serene kittehs, lounging atop walls and columns than at the historic site itself: … Continue reading

Flying into New York at night
The conditions were what pilots call “severe clear” from Charlotte to New York on Thursday night. I made sure (paying $44 to USAirways) that I had a window seat on the left side, and had a perfect view through an imperfect window of nearly every city and town from Charlotte to New York. Rolling by… Continue reading

Should Apple buy Nokia?
Mobile maps matter, and Apple now has the worst mapping you can get on a phone. The best, one would think (given the Apple vs. Google coverage) is Google’s. But maybe not, because Nokia has NAVTEQ, which rocks. Or so says Alexis Madrigal in the Atlantic, in a fascinating piece that visits just some of what NAVTEQ has… Continue reading

The only issue that matters
Geologists have an informal name for the history of human influence on the Earth. They call it the Anthropocene. It makes sense. We have been raiding the earth for its contents, and polluting its atmosphere, land and oceans for as long as we’ve been here, and it shows. By any objective perspective other than our… Continue reading

Why we have Silicon Valley
My son remembers what I say better than I do. One example is this: I uttered it in some context while wheezing my way up a slope somewhere in the Great Blue Hill Reservation. Except it wasn’t there. Also I didn’t say that. Exactly. Or alone. He tells me it came up while we were… Continue reading

One of the world’s great craters
When I visited the Upheaval Dome in 1987, I was sure it was an impact crater. But roadside displays and printed literature from Canyonlands National Park said otherwise. Clearly, they reported, this was collapsed salt dome. Since then German researchers have found evidence, through shocked quartz, of an impact. That now appears to be the prevailing theory. The… Continue reading

Bridges covered
My sister and I received a durable lesson in generosity in the summer of 1963, in the heart of Iowa. That was where our family’s 1957 Ford Country Sedan station wagon, towing our Nimrod pop-up camper trailer, broke down. It was on a Sunday morning in late June, heading south from Des Moines on I-35… Continue reading

So long, and thanks to the bird
Independent commercial alternative rock radio in Boston is heading to the grave. The Boston Phoenix‘ WFNX has been sold to Clear Channel, which — says the press release — will expand its “footprint” in Boston. (Bambi vs. Godzilla comes to mind.) Boston Business Journal suggests the signal’s fate will be to carry country music or Spanish programming. But it doesn’t… Continue reading

Radio news (and vice versa) in DC and Baltimore
A few days ago RadioInk reported that WTOP, the all-news radio station in Washington, D.C., is now the top-billing station in the nation. Two surprising things there. One is that Washington is the #7 market (behind New York, Los Angeles, Chicago, San Francisco, Dallas-Fort Worth and Houston-Galveston), and that in the latest ratings WTOP is #2 overall,… Continue reading

Aerial map mashing
Thanks to Jeff Warren (also here) of GrassRootsMapping and Public Laboratory, I now know — and am highly turned on by — the possibilities of mapping in the wild. That is, mapping by the 99.xxx+% of us who are not in the mapping business, and are in the best multiple positions to map the world(s)… Continue reading

Portraits of New York from altitude
On my way back from SXSW a couple weeks ago, I got some terrific shots of many things, including portions of Arkansas, Tennessee, Kentucky (including mountaintop mining), Virginia, Washington, D.C., Baltimore, Philadelphia, Trenton and Providence. Most of those aren’t uploaded yet, but I just put up the best of the bunch: this series of New… Continue reading

The death rattles of AM, then FM
Check the Arbitron radio listening ratings for Washington DC. You have to go waaaay down the list before you find a single AM station that isn’t also simulcast on FM. But then, if you go to the bottom of the list, you’ll also find a clump of Internet streams of local radio stations. You’ll see the… Continue reading

Discovering Raditaz
Read here about Raditaz, which I hadn’t heard about before. It’s a competitor to Pandora. Some differences: unlmited skips, no ads, geo-location. I started out by setting up three “stations,” based on three artists: Lowell George, Seldom Scene and Mike Auldridge. I’m on the Mike Auldridge station now, and guess what comes up? Dig: Not… Continue reading

What I’d like to say on the subway
When I was young, New York subways were dirty, noisy and with little risk of improvement. But, even if the maps weren’t readable (as with this 1972 example), there were lots of them. Now the subways are much nicer, on the whole, and being improved. But there is now a paucity of maps. In fact,… Continue reading

Beanstalk Connectivity
Logan Airport’s free wi-fi isn’t doing the job. (Latencies up to a second and a half, 7% packet loss.) In fact, the only reason I can continue with this post is that I’ve switched to my iPhone’s “personal hot spot,” which turns AT&T’s 3G data network to wi-fi I can use. On Logan’s connection I… Continue reading
