RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

you see the video of the kid who just set a new Rubik's Cube
solution time record? Collin Burns unscrambled Hungarian architect Erno Rubik's 3x3x3 cube in a mere 5.253 seconds
per the CubeComps website record list. It is an amazing spectacle
to see. Formal rules are set by the World Cube Association(WCA) for other format cubes like the 2x2x2, the 4x4x4 and the 5x5x5. My first thought
when watching the video is was how scrambling of the cube was randomized to assure fairness in unscrambling times?
It turns out that the WCA provides a program for setting
start patterns, which
must be used for official attempts. Full compliance with competition
rules is required for admission
into record books.
Have you ever solved a Rubik's Cube? I got my first one back around 1980, while in the USAF. It was a popular
pastime amongst the radar techs during long night shifts waiting for a call from an air traffic controller about
a malfunction of some sort. Solving two layers is a piece of cake, but getting that third layer down took quite
a while, as I recall. Once I finally figured it out, developing a routine based on how the colors were arranged
was pretty easy, so solving it quickly was mostly a matter of not having the darn thing either pop apart or get
caught in a configuration where the three planes were being improperly manipulated simultaneously. If you've done
the cube, you know what I am saying.
I still have my 4x4x4 cube, but have never been able to solve that fourth layer. For that matter, I can't honestly
say I've even solved three complete layers. Maybe some day if I ever get to retire, that will be added to the bucket
