A Geoengineer's Christmas List 2010 PDF Print E-mail

Wednesday, 22 December 2010 12:32

Christmas PresentSo last year at this time, I gave Santa my geoengineer’s Christmas list, but apparently I wasn’t good enough to get everything.  I did get two things off my list, the new FHWA Drilled Shaft Manual, and the New FHWA MSE Wall Manual, but that’s about it.  That’s like getting pink bunny PJ’s as a kid! So over the last year, I tried to be REALLY good, and this year I’ll just let last year’s list roll over with two additions:

An iPad

This year’s hottest gift would be great for reading my growing library of geotechnical papers, manuals, reports and books in PDF format.  I like the iBook app on my iPhone, especially being able to highlight and make notes and bookmarks.  And you can read an eBook allright, but try reading a scanned PDF report or paper on that little screen, doesn’t work too well.  I like the idea of having my entire library of technical papers, books and reports available at my fingertips!

And the coolest goodie on my list, the one I really want...
My Love Hate Relationship with Geocaching PDF Print E-mail

I am not a geocacher, but I've always thought it sounded like a fun thing to do when my kids get a little older. But this author has some unique insights into the hobby that I never thought about before. Thing like impacts to trails and the environment when you go off the trail, density of caches, potential hazardous terrain for people who may not be experienced in the outdoors and even bomb scares!

Geotechs rejoice, It’s “Dirt! The Movie” PDF Print E-mail

Dirt! The Movie is more about soil conservation and its role in the environment, but hey, it’s still pretty cool. I wouldn’t expect to see it at the megaplex though. And what gives with their mascot? It reminds me of a certain South Park character! Ok, he’s kind of cute, they call him “Digby.” I wonder if they have T-shirts?

More Nuclear Power – No Geologic Repository PDF Print E-mail

President Obama’s decision to cut funding to Yucca Mountain has, for me, been the most disappointing decision he has made so far in his presidency. And yet he has also professed his desire to increase the use of Nuclear Power Plants to meet the United States’ energy needs and reduce greenhouse gas emissions. Well, in my opinion, you can’t have it both ways.

People are concerned about the security risks of transporting spent nuclear fuel, and possible long term environmental risks. What about the risks of hundreds of “Obama Barrels” (to borrow a phrase by geoblogger Ontario-geofish) littered around our nuclear power plants for the next hundred years. posted this CNN video showing the dry storage of spent Nuclear Fuel at a Chicago area nuclear power plant. Check it out. Sorry about the rant, but this topic is a hot button with me.

Garmin Voice Studio: Turn Right [Morgan Freeman’s Voice] PDF Print E-mail
Written by Randy Post

Garmin Nuvi 1390T GPS navigation device Ok, not exactly. But Garmin just announced that their new Voice Studio software will allow users to record their own voices for navigation prompts and edit them in the software for use on their Nüvi. It is compatible with all nüvis except the nüvi 300 and 600 series. The process of recording the “few dozen” phrases is supposed to take about 30-minutes. As my title suggests, I think it would be cool to have celebrities contribute their voice to the navigation. I’m picturing Morgan Freeman or maybe Cheech Marin and Tommy Chong in character! Ok, that might get old. (Image from Garmin)

Oh, and they also just announced a cool adapter for your car that plugs into the standardized onboard diagnostics port (OBD II) that turns your GPS into a trip computer, monitoring things like RPM’s, temperature, battery voltage, emissions etc. It connects wirelessly to the GPS unit so the wires don’t get in the way of your driving. It will also give you error codes for the check engine light, some with descriptions of the problem. Both technologies will be showcased at this year’s CES in Las Vegas.

[Disclosure] I own a few shares of Garmin stock. [/Disclosure]

Most Popular Content of 2009 PDF Print E-mail

Best wishes for a happy and prosperous 2010 to all the readers of! I am grateful for all of my readers, visitors and sponsors for a great 2009 and I look forward to continuing to work in the new year towards making this site one of the best online resources for geotechnical engineers, geoengineers and all professionals in the geo-industry.

As is customary for bloggers at this time of year, I have listed below the top 100 stories published in 2009. Long-time readers of GeoPrac know that I don't like to rank the articles by total number of 'hits', since I think that biases the rankings towards the ones that have been published longer. Instead, I order them by hits per day. I think that works well when looking at popularity of content on a monthly basis, but just for grins I've also included the top 100 items of all time (based on total page impressions). Again, Happy New Year!
