An Impressively Nerdy Use of the Google Android

(source: RF Cafe)

Received in an e-mail: "This toy [Android  G1 phone] is a real nifty piece of technology. The nerdiest feature I've found so far is that you can use the internal accelerometer as a control for a Pac-Man download (instead of the trackball)... you tilt the phone as if Pac-Man were a ball in one of those kids toys, and he moves in the direction a ball would roll. One of the cooler features is another download that lets you change settings depending on where you are -- for instance, when I'm close to home (by GPS), I have it turn on Wi-Fi, turn my ringer down at night and up during the day... etc. Anyway -- back to work for me ... Lance"


Ever Heard of a Graphechon Tube?

(source: RF Cafe)

RF Cafe: RCA Graphechon Tube ad in the July 8, 1950 Saturday Evening PostNeither had I, until I saw it mentioned in an ad for RCA televisions in a 1950 edition of The Saturday Evening Post. My curiosity was piqued enough to do some research.

Text in the ad declares, "Scientists at RCA Laboratories work with split-seconds of time too infinitesimal for most of us to imagine. Their new electron tube, the Graphechon, makes it possible." Sound like the forerunner to the high persistence CRT?

How Bell Labs Creates Star Performers

(source: Harvard Business Review)

In the 1990s Bell Labs found that its most valued and productive engineers were not those with the highest IQs, but those who excelled in personal and group cooperation skills. In fields like computer programming, an 8:1 difference between the productivity of stars and average workers was reported. Prior to the study, managers assumed star performers must have higher IQs, be better problem solvers, or be driven by an enormous will to win.

RF Cafe: World DVD regions mapThe world is a segregated place as far as DVDs are concerned. The 6 DVD "regions" are shown in the map. Region 0 plays on all drives. 1st gen (RPC1) DVD drives can play any region, depending on installed software. RPC 2 drives come normally with a 5-change limit on regions, after which your drive is permanently locked to the last region it was set to. Resetting with pirate software is difficult at best. Many travelers have been burned when buying DVDs while abroad, then getting locked out back home. Caveat emptor.


Air Force Cyber Command

Secure communications have always been a major concern for national security. Lives, fortunes, and civilizations have depended on it. Message encoding, protection from interception, and vigilance against espionage have been the primary methods used by security and defense agencies. Air Force Cyber CommandDue to the advent of the Internet and similar technologies, the challenge has grown in such magnitude that on September 17, 2007, the Air Force Cyber Command (AFCYBER) was officially born. It is tasked with protecting the nation's secret information against unauthorized access from the realms of cyberspace.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


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...
