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. -

Current Affairs 2013- January International
Current Affairs 2013- January International The Fourth Meeting of ASEAN and India Tourism Minister was held in Vientiane, Lao PDR on 21 January, in conjunction with the ASEAN Tourism Forum 2013. The Meeting was jointly co-chaired by Union Tourism Minister K.Chiranjeevi and Prof. Dr. Bosengkham Vongdara, Minister of Information, Culture and Tourism, Lao PDR. Both the Ministers signed the Protocol to amend the Memorandum of Understanding between ASEAN and India on Strengthening Tourism Cooperation, which would further strengthen the tourism collaboration between ASEAN and Indian national tourism organisations. The main objective of this Protocol is to amend the MoU to protect and safeguard the rights and interests of the parties with respect to national security, national and public interest or public order, protection of intellectual property rights, confidentiality and secrecy of documents, information and data. Both the Ministers welcomed the adoption of the Vision Statement of the ASEAN-India Commemorative Summit held on 20 December 2012 in New Delhi, India, particularly on enhancing the ASEAN Connectivity through supporting the implementation of the Master Plan on ASEAN Connectivity. The Ministers also supported the close collaboration of ASEAN and India to enhance air, sea and land connectivity within ASEAN and between ASEAN and India through ASEAN-India connectivity project. In further promoting tourism exchange between ASEAN and India, the Ministers agreed to launch the ASEAN-India tourism website (www.indiaasean.org) as a platform to jointly promote tourism destinations, sharing basic information about ASEAN Member States and India and a visitor guide. The Russian Navy on 20 January, has begun its biggest war games in the high seas in decades that will include manoeuvres off the shores of Syria. -

Paul Baran, Network Theory, and the Past, Present, and Future of the Internet
PAUL BARAN, NETWORK THEORY, AND THE PAST, PRESENT, AND FUTURE OF THE INTERNET CHRISTOPHER S. YOO* Paul Baran’s seminal 1964 article “On Distributed Communications Networks” that first proposed packet switching also advanced an underappreciated vision of network architecture: a lattice-like, distributed network, in which each node of the Internet would be homogeneous and equal in status to all other nodes. Scholars who have embraced the concept of a flat network have largely overlooked the extent to which it is inconsistent with network theory, which emphasizes the importance of short cuts and hubs in enabling networks to scale. The flat network is also inconsistent with the actual way the Internet was deployed, which relied on a three- tiered, hierarchical architecture resembling what Baran called a decentralized network. However, empirical studies reveal that the Internet’s architecture is changing; as large content providers build extensive wide area networks and undersea cables to connect directly to last-mile networks, it is in the process of becoming flatter and less hierarchical. This change is making the network become more centralized rather than more distributed. As a result, this article suggests that the standard reference model that places backbones at the center of the architecture may need to be replaced with a radically different vision: a stack of centralized star networks, each centered on one of the leading content providers.

FOR IMMEDIATE RELEASE: NEWS CONTACT: August 10, 2009 Mark Wigfield, 202-418-0253 Email: [email protected] FCC ANNOUNCES PARTICIPANTS IN NATIONAL BROADBAND PLAN STAFF WORKSHOPS ON DEPLOYMENT, TECHNOLOGY Washington, D.C. -- The Federal Communications Commission’s staff workshops this week for the development of the National Broadband Plan will focus on deployment and technology. On Wednesday, industry, staff and public participants will examine wireline and wireless deployment, as well as what it means to be unserved or underserved by broadband, why areas or groups are unserved and underserved, and what actions the United States should take to help stimulate broader and faster broadband deployment. On Thursday, participants will examine both fixed and wireless broadband technologies that are affecting broadband networks today and that will likely affect them in the future. WHAT: National Broadband Plan Staff Workshops WHEN: Wednesday and Thursday, Aug. 12 &13.

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)). -

Pilarski, Division of Physical Medicine and Rehabilitation, Department of Medicine, 5-005 Katz Group Centre for Pharmacy and Health Research, University of Alberta, Edmonton, AB, Canada, T6G 2E1. [email protected] ABSTRACT This work presents an overarching perspective on the role that machine intelligence can play in enhancing human abilities, especially those that have been diminished due to injury or illness. As a primary contribution, we develop the hypothesis that assistive devices, and specifically artificial arms and hands, can and should be viewed as agents in order for us to most effectively improve their collaboration with their human users. We believe that increased agency will enable more powerful interactions between human users and next generation prosthetic devices, especially when the sensorimotor space of the prosthetic technology greatly exceeds the conventional control and communication channels available to a prosthetic user. To more concretely examine an agency-based view on prosthetic devices, we propose a new schema for interpreting the capacity of a human-machine collaboration as a function of both the human’s and machine’s degrees of agency. -
