Detecting Aircraft Before There Was Radar

How air attacks were detected before  radar.

Beginning in the middle of the 1930s, engineering labs in the U.S. and Europe were experimenting with radar systems. Early radars did not have the slick plan position indicator (PPI) displays that modern systems use for plotting target movement for indication of azimuth (direction) and range (distance). Instead, oscilloscopes showed radar returns as amplitude blips along a time base that represented range. Azimuth was determined by where the operator pointed the antenna (rotating versions came later). Since radar cross section stealth technology had not been invented yet, the amplitude of the signal was useful a measure of the size of the target.

Calories Posted on Menus Makes Little Difference in What Children and Teens Order

calories on menus

Children and adolescents noticed the calories posted on the menu but the calorie counts made little difference.

Requiring fast-food restaurants in New York City to post calorie counts on menus did little to cut the number of calories children and teens consumed, U.S. researchers said on Tuesday.

Internet Protocol version 6

Who could have guessed that 4.3 billion Internet connections wouldn’t be enough?  Certainly not Vint Cerf.

In 1976, Mr. Cerf and his colleagues in the R.& D. office of the Defense Department had to make a judgment call: how much network address space should they allocate to an experiment connecting computers in an advanced data network?

The More Unusual Your Username the Easier it is For Marketers and Scammers to Track You

computer caution

Your unusual username could allow marketers and scammers to build a more complex picture of you.

By creating a distinctive username—and reusing it on multiple websites—you may be giving online marketers and scammers a simple way to track you. Four researchers from the French National Institute of Computer Science (INRIA) studied over 10 million usernames—collected from public Google profiles, eBay accounts, and several other sources. They found that about half of the usernames used on one site could be linked to another online profile, potentially allowing marketers and scammers to build a more complex picture the users.
