ECN’s Veteran’s Day tribute: Remembering those who’ve served
November 9, 2012 2:50 pm | by Jason Lomberg, Technical Editor | Articles | Comments
On the cusp of Veteran’s Day, I’m reminded that a disproportionate number of our friends and colleagues served in the military. And that makes me proud to work in this industry. ECN — and her parent company, Advantage Business Media — is no exception. You can’t swing a dead cat (or give a resounding Hoooah!) without hitting a veteran.

The green death
April 30, 2013 3:45 pm | by M. Simon, Technical Contributor | Blogs | CommentsBeing "green" has gone from a technical effort to economically reduce energy use and avoid waste where such avoidance makes sense to actively reducing our effectiveness to show how committed we are to the Green Religion. And there is so much of this going on. In my opinion we would be much better off worshiping trees. Or cows.

Schools should take a pass on essay grading software
April 16, 2013 4:16 pm | by Chris Warner, Executive Editor | Articles | CommentsOne of the joys of high school and college was receiving my blue essay book back from my teacher or professor. I couldn’t wait to read their comments in the columns of the book, especially when one of my essays was laden with jokes or sarcasm. But that was often a two-way street, as when my thesis statement would indicate my essay was going to go in a direction my instructor found dubious.
