Stayin’ Alive

From our earliest days, we are constantly warned about various dangers in our lives, and we can all remember advice like the “stop, look and listen” before crossing train tracks or avoiding taking candy from strangers.

The Oklahoma Twister Relief Concert

On May 20, 2013, a massive and powerful tornado stuck the town of Moore, OK, a suburb located about halfway between Norman and Oklahoma City. The twister was given the maximum EF-5 strength rating by the National Weather Service. Tragically, the aftermath of its two-mile-wide swath of fury left hundreds of injuries, some two dozen deaths (including seven children killed when a school collapsed) and entire neighborhoods flattened, with more than an estimated billion dollars in damage to homes and businesses.

Generators and Portable Power, Part 3

In the July 2013 issue of FRONT of HOUSE, our second article on portable power distribution discussed grounding and bonding specifics of portable generators, including small generators that are “floating neutral” configured.

Lsst week, I had the unique privilege of spending the day with Fernando Guzman, Solid State Logic product specialist and point man for the Live console project here in the USA.

A Recording Studio Tackles Live-Sound Education

It’s a tough economic time for music, but if you have to be in that business, live music is where you want to be. While the overall U.S. music industry can expect to see annual growth of just over 1 percent through 2017, according to a recently released PricewaterhouseCoopers industry analysis, the report projects that the concert business will grow at a compound annual growth rate of 3 percent through the same period. In other words, live-performance music revenues are projected to be triple those of the music industry as a whole going forward.

Did you ever play the video game Tetris? Tetris was released in the mid-1980s and is reportedly the first video game ever to be exported from what was then the Soviet Union to the United States. It’s one of the most popular video games of all time (even I’ve played it), and has been ported to game consoles ranging from the Commodore 64 computer to Game Boy to the iPhone.
