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. -

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)). -

I: the Conception
Excerpt from: Mayo, Keenan and Newcomb, Peter. “How the Web Was Won,” Vanity Fair, July 2008. I: The Conception Paul Baran, an electrical engineer, conceived one of the Internet’s building blocks—packet switching— while working at the Rand Corporation around 1960. Packet switching breaks data into chunks, or “packets,” and lets each one take its own path to a destination, where they are re-assembled (rather than sending everything along the same path, as a traditional telephone circuit does). A similar idea was proposed independently in Britain by Donald Davies. Later in his career, Baran would pioneer the airport metal detector. Paul Baran: It was necessary to have a strategic system that could withstand a first attack and then be able to return the favor in kind. The problem was that we didn’t have a survivable communications system, and so Soviet missiles aimed at U.S. missiles would take out the entire telephone- communication system. At that time the Strategic Air Command had just two forms of communication. One was the U.S. telephone system, or an overlay of that, and the other was high-frequency or shortwave radio. So that left us with the interesting situation of saying, Well, why do the communications fail when the bombs were aimed, not at the cities, but just at the strategic forces? And the answer was that the collateral damage was sufficient to knock out a telephone system that was highly centralized. Well, then, let’s not make it centralized. Let’s spread it out so that we can have other paths to get around the damage. -

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.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced. -

Personal Computing Thomas J. Bergin ©Computer History Museum American University Recap: Context • By 1977, there was a fairly robust but fragmented hobbyist-oriented microcomputer industry: – Micro Instrumentation Telemetry Systems (MITS) – Processor Technology – Cromemco – MicroStuf – Kentucky Fried Computers • Two things were needed for the personal computer revolution: 1) a way to store and retrieve data, and 2) a programming language in which to write applications.

Fall 2010 1 INDEPENDENT PUBLISHERS GROUP – FALL 2010 New Titles
INDEPENDENT PUBLISHERS GROUP Fall 2010 1 INDEPENDENT PUBLISHERS GROUP – FALL 2010 New Titles A Glee-ful salute for the legions of “gleeks” who can’t get enough of this new hit show Don’t Stop Believin’ The Unofficial Guide to Glee Erin Balser and Suzanne Gardner • $20,000 marketing budget; co-op available • Glee was the most successful new show of the 2009 television season, winning the Golden Globe Award for Best Television Series—Musical or Comedy and the Screen Actors Guild Award for Outstanding Performance by an Ensemble in a Comedy Series • The final episode of Glee’s first season was watched by 8.9 million American viewers The fictional high school milieu of Glee—the wildly popular Fox television series that debuted in 2009—is celebrated and dissect- ed in this detailed companion to the series. The songs, the stu- dents, and the idiosyncratic teachers all come under affectionate scrutiny in this fan’s compendium. The familiar dramas that beset the members of the McKinley High glee club, New Directions, have struck a chord with a wide audience that ranges from tweens to 20-somethings and beyond. Glee watchers will relish this analysis of every relationship, fashion statement, insult, and triumph that is plumbed for greater meaning and nos- talgic pleasure. The music that is such a key element of the show—a careful mix of show tunes and popular hits—is also thoughtfully discussed. Trivia, in-jokes, profiles of the actors, and a detailed synopsis of the show’s first season make this an indis- pensable reference for the growing fan base of “gleeks” that are devoted to this fledgling television sensation.
