Educational topics and useful things to know.

Unpacking my Asus Eee PC

How long does it take to get from sealed box to surfing the net for a beginner who has never seen this machine in person before? I thought I’d video the process and find out. It would have gone quicker had I known that the Eee connects to WiFi automatically and gives no obvious indication of this. I spent time trying to establish a connection when one already existed. Of course I have that locked down now so it does not go fishing for open access points but only connects to my own WAP secured access point.

What Does this Label Lead You to Believe?

Ocean Spray 100% Juice

“Ocean Spray 100% Juice” means what, exactly?

Ruby Red Grapefruit, 100 percent juice, no sugar added. And the price is higher than an equivalent amount of refrigerated fresh 100 percent orange juice, so it must be pure grapefruit juice right? Wrong. It does not say “pure grapefruit juice” and it’s not.

If one reads the ingredients one learns that it contains grapefruit juice plus two other juices. Talk about deceptive labeling. I hope you are reading the labels in the “juice” section of the market. The only pure juices one can find these days are certain grape juices and most prune juices. All others, like 95 percent of the “juices”, are blends and “cocktails”, and are also spiked with high fructose corn syrup to help you get fat faster. Why? If I wanted soda pop or candy I can go to the soda pop or candy sections of the market. This is supposed to be the juice section, or it used to be anyway.

Be very careful when buying fruit juices. “Pomegranate juice” is mostly grape juice. “Blueberry” is mostly grape juice. Read the label and you’ll find that nearly all of them except grape and prune are not what they appear to be.

Switch Inventor Honored

After decades of controversy over inventorship, the inventor of the switch was recognized and honored at a recent awards banquet of the International Organization of Electrical Engineers. Professor Turnonanof (1871-1929) was posthumously awarded the Inventor of the Year Award and inducted into the IOEE Hall of Fame. The professor’s son, Clarence “Click” Turnonanof, was present to accept the awards and give a moving presentation of his father’s achievements.

In the early days, Turnonanof’s invention was embodied in an open frame style like this:

Later, he developed a more advanced and miniaturized form of his famous invention:

A spokesperson for the IOEE said that the organization was exploring the possibility of setting up a Turnonanof scholarship.
