INTRODUCTION As the great Yogi Berra redundantly said, "It's like deja vu all over again."1 For IP scholars and practitioners of my generation, Ora­ cle Corporation's lawsuit alleging that Google's Android mobile plat­ form infringes copyright in the Java application program interface ("API") elements has been a stroll down memory lane. 2 Or perhaps less nostalgically for those in the software industry, a zombie horror film set in Silicon Valley.3 1. See YOGI BERRA, THE YOGI BOOK: I DIDN'T SAY EVERYIBING I SAID 9 (1998) (ex­ plaining that the deja vu quotation was inspired by Yankees' sluggers Mickey Mantle and Roger Maris's repeated back-to-back home runs in the early 1960s). 2. As Judge Alsup noted in an early ruling in the Oracle litigation, "[t]he term API is slippery."

From the title of this paper you may have guessed that I am not very impressed with the guys in Redmond. One might even say that my dislike for Microsoft is a pet hate gone out of control in an almost quixotic fashion. Why is this? Of course I have been accused of personal antipathy, of being jealous of Bill Gates and his billions, and of being prejudiced against all things Microsoft without any reason whatsoever. None of this is true. I have nothing personal against Bill Gates. Why should I? I don't know the man, I've never met him. I agree with those who say he might be the most successful salesman in history.

  • Bill Gates – a Story of Success
    Bill Gates – A story of Success William H. Gates is chairperson and chief software architect of Microsoft Corporation, the worldwide leader in software services and Internet technologies for personal and business computing. Bill Gates was born on October 28, 1955 in a family having rich business, political and community service background. His great-grandfather was a state legislator and a mayor, his grandfather was vice president of national bank and his father was a lawyer. Bill strongly believes in hard work. He believes that if you are intelligent and know how to apply your intelligence, you can achieve anything. From childhood Bill was ambitious, intelligent and competitive. These qualities helped him to attain top position in the profession he chose. In school, he had an excellent record in mathematics and science. Still he was getting very bored in school and his parents knew it, so they always tried to feed him with more information to keep him busy. Bill’s parents came to know their son's intelligence and decided to enroll him in a private school, known for its intense academic environment. It was a very important decision in Bill Gate's life where he was first introduced to a computer. Bill Gates and his friends were very much interested in computer and formed "Programmers Group" in late 1968. Being in this group, they found a new way to apply their computer skill in university of Washington. In the next year, they got their first opportunity in Information Sciences Inc. in which they were selected as programmers. ISI (Information Sciences Inc.) agreed to give them royalties whenever it made money from any of the group’s program.

  • Bill Gates, "Keynote Address to the Creating Digital Dividends Conference" (18 October 2000)
    Voices of Democracy 2 (2007): 227‐243 French 227 BILL GATES, "KEYNOTE ADDRESS TO THE CREATING DIGITAL DIVIDENDS CONFERENCE" (18 OCTOBER 2000) Sandra L. French Radford University Abstract: In the first twenty‐five years of Microsoft, Bill Gates established himself and his company as a powerful social force in the advancement of technology. Gates' keynote address to the 2000 Creating Digital Dividends conference, however, surprised attendees and the press by arguing against the establishment of technology in underdeveloped nations in favor of promotion world equity in healthcare. This speech presents a major shift in Gates' persona, and was largely derided as insincere philanthropy. Key Words: digital divide, technology, Bill Gates, health, crisis, computers. The influence of Bill Gates on technology, society, and global economics is undisputed. He co‐founded Microsoft in 1975 with the vision of a "computer on every desk and in every home"—a computer that would, of course, be running Microsoft software. In the first twenty‐five years of Microsoft, their software products have become the primary method for working, obtaining information, and communicating online. Gates' tenure as Microsoft's chief executive has come to symbolize for many the dawn of the information age and the resultant digital capitalism. Images of Gates are filtered to the public through the mass media and the increasing technological literacy of the global world. Technology is a popular subject of study for contemporary rhetoricians, and has been examined at the micro and macro levels. While much has been written about the development of the personal computer and its impact on society, little attention has been given to technology's business leaders.

  • E Bill Gates
    E Bill Gates Bill Gates nacque il 28 Ottobre del 1955 a Seattle. Nel 1968, l'anno in cui si iscrisse alla prestigiosa scuola privata Lakeside , Gates e i suoi compagni ebbero accesso per la prima volta ad un computer , un DEC PDP- 11 di proprietà della Computer Center Corporation Alla fine del 1968, Gates, Allen ed altri due hacker del gruppo (Ric Weiland e Kent Evans), fondarono la Lakeside Programmers Group. Una società li assunse per trovare le debolezze del loro sistema, ed in cambio diede loro tempo illimitato al computer. Nel marzo del 1970 la società chiuse e la Lakeside Programmers Group dovette cercare altri modi per ottenere accesso ad un computer. Trovarono la Information Science Inc ., che li accettò per la creazione di un programma di gestione paghe, promettendo in cambio, oltre all'accesso al computer, anche una royalty se dai programmi del gruppo si fossero avuti dei guadagni. In quel periodo accade che gli altri tre del gruppo chiesero a Gates di lasciare il gruppo, perché il lavoro non sembrava sufficiente per tutti, ma Gates li convinse a tenerlo con loro. Successivamente, nel 1972, Bill e Paul fondarono la Traf-O-Data, che progettò un computer per misurare il traffico stradale La Traf-O-Data durò fino alla fine degli studi di Bill. I due lavorarono insieme anche per informatizzare il sistema di gestione della scuola . Negli ultimi anni di scuola, ebbero l'invito dalla TRW, non solo di trovare le debolezze del loro sistema ma anche di programmare i rimedi.Nel 1973, Gary Kildall scrisse un semplice sistema operativo nel suo linguaggio PL/M, il CP/M (Control Program/Monitor), e lasciò i sorgenti accessibili a tutti per scopi didattici.

A video montage is embedded in the article linked above. 1. Mobile. CNET names the Motorola Moto G7 as a great budget phone. Their high-end nominee was the Samsung Galaxy Note 10 for its mix of style and substance. On a personal note, pardon the pun, the Note 10 was not prone to spontaneous combustion. Based on the additional features and a price drop, the iPhone 11 was noted in the middle. 2. Home Entertainment. Two TVs led this category. The TCL 6-Series image and color quality rival that of much more expensive televisions. The LG OLED B9 presented unmatched contrast and viewing angles.

The 4004 circuit was built of 2,300 transistors. Originally designed for the Japanese company Busicom to be used in their line of calculators. The chief designers of the chip were Stan Mazor, Federico Faggin and Marcian “Ted” Hoff of Intel and Masatoshi Shima of Busicom.

The 8080 was designed and manufactured by Intel, released in April 1974 and sold for $360. The 6800 was produced by Motorola and released shortly after the Intel 8080 in 1975. The 6502 was designed by MOS Technologies and introduced in September 1975. The Z80 was designed and manufactured by Zilog from 1976 onwards. It was widely used both in desktop and embedded computer designs and is one of the most popular CPU's of all time 4 2 2/18/20 Altair 8800 A microcomputer design announced in January 1975, based on the Intel 8080 CPU.
