How Did They Get to the Moon Without Powerpoint?
How Did They Get to the Moon Without PowerPoint? Mordechai (Moti) Ben-Ari Department of Science Teaching Weizmann Institute of Science [email protected] Keynote speech at the Finnish Computer Science Society, May, 2003. 1 Developing a Technology The invention of writing, however, was the invention of an entirely new Let me start with a description of one of my first technology.[3, p. 9] full-time jobs: There is something to be said for this definition: I developed a technology for data min- do you remember those old movies that show “typ- ing in order to consolidate enterprise- ing pools,” where rows and rows of people, usually customer relations. women, sat pecking away at keyboards all day? Since I held that job in the early 1970s, clearly I would not have described my work in this terminol- ogy! What I actually did was: I wrote a program that read the system log, computed usage of CPU time and printed reports so that the users could be billed. My point in this talk is that hi-tech in general and computer science in particular did not begin in the 1990s, but that we have been doing it for decades. I believe that today’s students are being fed a lot of marketing propaganda to the contrary, and that they Well, things haven’t changed all that much! have completely lost a historical perspective of our discipline. I further believe that we have a respon- sibility as educators to downgrade the hype and to give our students a firm background in the scientific and engineering principles of computer science. -

Growth of the Internet
Growth of the Internet K. G. Coffman and A. M. Odlyzko AT&T Labs - Research [email protected], [email protected] Preliminary version, July 6, 2001 Abstract The Internet is the main cause of the recent explosion of activity in optical fiber telecommunica- tions. The high growth rates observed on the Internet, and the popular perception that growth rates were even higher, led to an upsurge in research, development, and investment in telecommunications. The telecom crash of 2000 occurred when investors realized that transmission capacity in place and under construction greatly exceeded actual traffic demand. This chapter discusses the growth of the Internet and compares it with that of other communication services. Internet traffic is growing, approximately doubling each year. There are reasonable arguments that it will continue to grow at this rate for the rest of this decade. If this happens, then in a few years, we may have a rough balance between supply and demand. Growth of the Internet K. G. Coffman and A. M. Odlyzko AT&T Labs - Research [email protected], [email protected] 1. Introduction Optical fiber communications was initially developed for the voice phone system. The feverish level of activity that we have experienced since the late 1990s, though, was caused primarily by the rapidly rising demand for Internet connectivity. The Internet has been growing at unprecedented rates. Moreover, because it is versatile and penetrates deeply into the economy, it is affecting all of society, and therefore has attracted inordinate amounts of public attention. The aim of this chapter is to summarize the current state of knowledge about the growth rates of the Internet, with special attention paid to the implications for fiber optic transmission. -

Assignment #4: Big−O, Sorting, Tables, History − Soln
Assignment #4: Big−O, Sorting, Tables, History − Soln 1. Consider the following code fragment: for (int pass = 1; pass <= 10; pass++) { for (int index = 0; index < k; index += 10) { for (int count = 0; count < index; count++) { do_something(); } } } Assuming that the execution time of do_something() is independent of k, what is the most accurate description of the worst case run−time for this algorithm? a) O(1) b) O(k ) c) O(k log(k) ) 2 d) O(k ) ← 3 e) O(k ) Briefly explain your reason for choosing this answer. The outer loop executes (10+1-1)/1=10 times, and the middle loop executes (k-0)/10 = k/10 times for each execution of the outer loop. The innermost loop executes no times at first, then once, then twice, until k-1 times the last time that the middle loop executes, and the body runs O(1) time. Thus the run time is 10*(0+1+2+?+k- 1)*O(1) = O(k2). 2. Consider the following code fragment: for (int pass = 1; pass <= k; pass++) { for (int index = 0; index < 100*k; index += k) { do_something(); } } Assuming that the execution time of do_something() is O(log(k) ), what is the most accurate description of the worst case run−time for this algorithm? f) O(log(k) ) g) O(k ) h) O(k log(k) ) ← 2 i) O(k ) 2 j) O(k log(k) ) Briefly explain your reason for choosing this answer. The outer loop is executed (k+1-1)/1 = k times, the inner loop is exectuted (100k-0)/k = 100 times, and the innermost block takes time O(log(k)). -

Former Vice President Al Gore and Internet “Father” Vint Cerf Praise the ICANN Model
FOR RELEASE: June 3, 2009 CONTACTS: Brad White Director of Media Affairs Ph. +1 202.429.2710 E: [email protected] Michele Jourdan Corporate Affairs Division Ph. +1 310.301.5831 E: [email protected] Former Vice President Al Gore and Internet “Father” Vint Cerf Praise the ICANN Model Comments Precede Hill Hearings on Ties to U.S. Government Washington, D.C. … June 3, 2009…. Former U.S. Vice President Al Gore has joined a leading Internet founder in acknowledging the success of the multi-stakeholder, bottom up governance of the Internet’s name and address system that the Internet Corporation for Assigned Names and Numbers (ICANN) embodies. “Twelve Years ago as Vice President, I led an interagency group charged with coordinating the U.S. government’s electronic commerce strategy. The formation of ICANN was very much a part of that strategy,” Gore said. The former Vice President’s comments come on the eve of Congressional hearings on ICANN’s relationship with the U.S. government and on the non-profit corporation’s proposed expansion of top- level domains. “The Internet’s unique nature requires a unique multi-stakeholder private entity to coordinate the global Internet addressing system without being controlled by any one government or special interest. What we have all those years later is an organization that works,” said Gore. “It has security as its core mission, is responsive to all global stakeholders and is independent and democratic. We should make permanent those foundations for success.” Gore’s praise parallels the comments of Vint Cerf, a man considered by many to be the one of the fathers of the Internet. -

Features of the Internet history The Norwegian contribution to the development PAAL SPILLING AND YNGVAR LUNDH This article provides a short historical and personal view on the development of packet-switching, computer communications and Internet technology, from its inception around 1969 until the full- fledged Internet became operational in 1983. In the early 1990s, the internet backbone at that time, the National Science Foundation network – NSFNET, was opened up for commercial purposes. At that time there were already several operators providing commercial services outside the internet. This presentation is based on the authors’ participation during parts of the development and on literature Paal Spilling is studies.
