An indicator commonly used in acid/base titrations which turns colourless in acidic solutions and is otherwise (in the concentrations commonly used in labs at least) pale pink. And I mean very pale, so it is f*cking useless without a colour chart and very good eyes. It also turns colourless in solutions of pH greater than 12.
The Kastle-Meyer test shows the presence of blood; a dry swab or piece of filter paper is used to collect a sample, then a few drops of phenolphthalein dissolved in alcohol (due to its insolubility in water) is added, followed by a few drops of hydrogen peroxide - this mixture will turn pink in the presence of blood. If you've ever watched 5 seconds of CSI, you have seen someone doing this.
In the past phenolphthalein has been used as a laxative, but is no longer used due to fears that it is carcinogenic.

Person A - "I'm using phenolphthalein but I can't tell if the solution's acidic yet..."
Person B - "Just make up some results - it'll be more accurate."

A four CPU processor released by AMD Inc. in the year 2007, in the Agena core variant, and in the year 2009, with the Deneb core variant.
The Agena variant of the Phenom processor had a defect (errata) which made all of these chips somewhat slower than AMD's high range dual core chips and substantially slower than its competition's quad core chips. This hurt AMD's reputation and caused it to lose prestige and footing in the market.
The Deneb variant has no errata issues and is fairly competitive with other quad core processors by competing manufacturers.

The benchmarks published on most computer enthusiast websites confirm that the Phenom 9500 is actually slower in most applications than the Athlon X2 6000.
