Slashdot.org has daily injections of items of interest to geeks - and non-geeks (AKA "normal people") for many of the items. Here are a couple of the latest items that I found particularly interesting this morning. Enjoy or not - your choice!
That last sentence gets my attention. A "very well-controlled beam" is mostly under the control of the driver, depending upon how s/he maintains the vehicle. I get sick, sick, sick of having vehicles follow me with wildly misaligned headlamps. (Part of the issue is the prevalence of hi-jacked pickup trucks in my neck of the woods!) I am prone to slowing (or changing lanes) to force them to pass me - which - isn't exactly how I wish to drive. However, being blinded by following headlamps isn't good, either. Unfortunately, my latest car has an "auto-dim" rear-view mirror which doesn't dim enough when it does measure the triggering intensity of light.
