Sub-families of the 74xx series IC’s are available relating to the different technologies used to fabricate the gates and they are denoted by the letters in between the 74 designation and the device number. There are a number of TTL sub-families available that provide a wide range of switching speeds and power consumption such as the 74 L 00 or 74 ALS 00 AND gate, were the “L” stands for “Low-power TTL” and the “ALS” stands for “Advanced Low-power Schottky TTL” and these are listed below.
Bill Gates is married to Melinda French (married in 1992). They have three children Jennifer (1996), Rory (1999) and Phoebe (2002). With his wife, Bill Gates formed the Bill & Melinda Gates Foundation. Bill Gates says much of the inspiration came from the example of David Rockefeller. Like Rockefeller, Gates has sought to focus on global issues ignored by the government; he also expressed an interest in improving the standards of public school education in the US. He has appeared with Oprah Winfrey to promote this objective. In respect to charitable, philanthropic activities Gates has also received encouragement from investor Warren Buffet, who has given away $17 billion, through the Gates Foundation.
Domingos’s book, released last year by Basic Books, is an introduction to machine learning—”the scientific method on steroids”—and how it relates to everyday life. What we’re really searching for with all this AI tech, argues Domingos, is an ultimate “master” algorithm. He writes: “If it exists, the Master Algorithm can derive all knowledge in the world—past, present, and future—from data. Inventing it would be one of the greatest advances in the history of science.”
