So you probably couldn’t order any of these things and expect to get them to your GIS colleague before the Christmas holiday, but they would make a great belated present! Geo-Tee has these T-Shirts and stickers for GIS nerds enthusiasts. Via Slashgeo. (Images by Geo-Tee)

GeoPrac Site Problems - Working on It PDF Print E-mail
Written by Randy Post   
Monday, 16 November 2009 11:36

[Update 11/16/09 12:52] I fixed the sponsor banner issue, but I'm still looking into what's causing the IE 7 error. Despite my fondness for Firefox, I realize a large percentage of users still have IE 7 and this is a serious issue. The site appears to be working fine in Firefox and IE 8. But like I said, I'll keep working on it. [/Update]

I just noticed some sponsor banner are not displaying properly on the site. I'm looking into it as quickly as I can. These issues may or may not be related to some Internet Explorer 7 issues where IE gives the following error when trying to display the GeoPrac.net site: "Internet Explorer cannot open the Internet Site. .. Operation aborted." It's some kind of JavaScript issue, but I rely on third party software and plugins so heavily on this site, it might take me a bit to track down the poblem.

In typical Microsoft fashion, their solution is to upgrade to IE 8. But I still get some warning messages there myself. I usually use Firefox, but even with that I'm still getting the issues with the banners.

Your patience is appreciated in the meantime as I try to get it sorted out. If you have any observations with regards to your particular browser configuration, let me know (leave a comment).

ASCE G-I: Proposed “Journal of Geotechnical Engineering Practice” PDF Print E-mail
Written by Randy Post   
Tuesday, 15 September 2009 00:27

Most geotechs are familiar with the Journal of Geotechnical and Geoenvironmental Engineering (JGGE), one of the (if not the) premier journal in the industry. It’s published by the ASCE’s Geo-Institute (G-I) and accounts for about 20% of the revenue of the G-I organization.

The G-I’s President, Dr. Jean-Louis Briaud, convened a task force in early 2009 to investigate if the JGGE is “adequately serving as a venue for practice oriented papers.” According to the final report from the Proposed "Journal of Geotechnical Engineering Practice" Task Force, the reason for the task force is that:

Social Media / Social Networking Poll PDF Print E-mail
Written by Randy Post   
Sunday, 06 September 2009 00:10

Twitter, Facebook, YouTube, LinkedIn and other social media and social networking websites have become absoutely huge in this day and age. I have prepared a brief survey to see how people in the geotechnical engineering, engineering geology and geoconstruction fields use these technologies, and if there is a potential for an extension of these technologies to be applied to our industry in the form of a GeoPrac.net feature.

And don't be shy if you don't use social networking or even if you feel strongly against it. I need hear from you too!

Take the Survey! (Powered by Google Spreadsheet)

Landslide Video But Not What You Think PDF Print E-mail
Written by Randy Post   
Friday, 14 August 2009 21:41

There is nothing funny about landslides, particularly when you consider the tremendous loss of life that happens all the time around the world, most recently in Taiwan, China, Sierra Leone and elsewhere. But the well known humor site, the Onion has taken a pretty good crack at this usually unfunny subject in their video “news” clip Reporter In Helicopter Pretty Sure Landslide Down There Somewhere. Its a very amusing video that’s really about journalists and their attempts to get the scoop about a story, not really about landslides at all. Click through for the embedded video. Happy weekend.

Geotechnical Engineering Interest Declining? PDF Print E-mail
Written by Randy Post   
Wednesday, 29 July 2009 00:14

I came across yet another Google Beta product called Google Insights for Search. It lets you see the popularity of a particular search term over time. Currently the data goes back to 2004. It normalizes the data based on the most popular search term in the period, so you can’t glean any absolute data about searches, but it can show you how a particular search term or terms are trending.

I took a look at the keywords geotechnical and geotech and saw an interesting trend.  Searches for the word geotech (red curve below) stayed pretty consistent at about 18-22% of the peak interest in the term geotechnical. But you can see in the figure below that searches for geotechnical have dropped by 60% since 2004 (blue curve). (Image by Google)

Google Insights for Search results for geotechnical and geotech

What could be causing this decline? Is it simply a result of more complicated or specific searches replacing the general “geotechnical” search? Or does it truly represent a declining interest in geotechnical engineering? I don’t know the answer, but I welcome any insights you might have on this in the form of comments.

Just for comparison, I checked out a few other searches as well. I tried to group searches that had similar volumes otherwise the lower traffic volume ones get lost at the bottom of the chart. Some of them show a similar downward trend. I have got to imagine that the overall number of searches performed by everyone, including those in the geotechnical and geological communities, has to have increased since 2004. So if these searches are declining, which ones are increasing? If you find that out, be sure to let me know.

Indefinite "Temporary" Nuclear Waste Storage and the Need for Nuclear Power PDF Print E-mail
Written by Randy Post   
Thursday, 23 July 2009 21:24

image Since the Yucca Mountain nuclear waste repository has gotten the axe from President Obama, nuclear power plants around the country are faced with the prospect of virtually indefinite "temporary" storage of their nuclear waste in the form of spent fuel rods. The US Department of Energy has a legal obligation to find a permanent disposal facility for the spent fuel, and the agreements currently in place presumed that Yucca Mountain would be accepting nuclear waste by 2025 which clearly won't happen. (Photo of dry cask temporary storage method for spent nuclear fuel from Connecticut Yankee). More after the break.

Apollo 11 Lunar Landing 40th Anniversary (not 20th!) PDF Print E-mail

View of Lunar Module footpad, subject of much geotechnical analysi I’ll be brief since I have already mentioned this in a previous post and in the July GeoPrac newsletter. But today was the 40th Anniversary of the first time humans set foot on the moon. I’m embarrassed to say, but I mistakenly noted this historic anniversary as the 20th instead of the 40th anniversary in both of the above links. I’m surprised nobody called me on this, but I guess you ridiculed me in private. If you haven’t already, check out the wonderful article by Ed Nowatzki on the geotechnical engineering aspects of the lunar lander…fascinating reading, even for non-geotech types.

Astronaut Edwin E. Aldrin near a leg of the Lunar Module [Editor] For crying out loud. Two weeks later, and I finally notice the title of my post was 20 years off! Its the 40th anniversary, not the 20th. Sheesh! [/Editor] It's hard to believe that such a tremendously historic scientific and cultural event is celebrating its 20th Anniversary this month! On July 20, 1969, Apollo 11 astronauts "Buzz" Aldrin and Neil Armstrong became the first humans to set foot on the Moon. [Astronaut Edwin E. Aldrin near a leg of the Lunar Module. (From enwiki), NASA Source]

One of the first featured articles I published on GeoPrac was a remarkable narrative by my NCS Consultants, LLC colleague, Dr. Ed Nowatzki, sharing his recollections of his work on the geotechnical (soils engineering)aspects of the design of the first lunar lander or LM. I was doubly reminded of his article recently, first because of the milestone anniversary, but also because a different spacecraft was having some soil-related trouble on the Planet Mars.
