True: “Expedia is charging more for flights because you look for them!”

Popular travel web sites, and at least some airlines, gradually jack up the prices shown if you search for many flight options in a single login session.

“Apple CEO Tim Cook says 4-year degree not necessary for coding”

Software development has been evolving (no surprise!) Today much software can be written using tools that make development easier than ever.

“5G” is mostly about adding capacity in major markets, and offering a broadband-like wireless connection

5G is not likely to solve much of the rural access issue. Mainly, its a high capacity, faster wireless link at millimeter wavelengths, meaning relatively short distances from base stations.

However, since phone companies already offer wired services, in many cases consumers will not see an additional market competitor.
