  1. Alan Turing Centennial - The Trustees of Princeton University
    Held May 10-12, 2012, the Princeton Turing Centennial Celebration honored Turing's time at Princeton, where he earned a Ph.D. in 1938. This event also celebrated the pivotal role that Turing's thesis played in the evolution of computer science, and the broad reach of his work. Watch lecture videos by the weekend's speakers, who gathered to mark the hundredth anniversary of the birth of the "father of computer science." The site also offers Turing's doctoral dissertation, graduate file, and university portrait. more>>

  2. Dictionary of Algorithms, Data Structures, and Problems - Paul E. Black
    Originally compiled for the CRC Dictionary of Computer Science, Engineering and Technology: a dictionary of algorithms, algorithmic techniques, data structures, and archetypical problems, with related definitions. Algorithms include common functions, such as Ackermann's function. Problems include traveling salesman and Byzantine generals. Some entries have links to further information and implementations. Index pages list entries by area, for instance sorting, searching, or graphs, and by type. A page also lists all implementations. more>>

  3. Don Knuth's Home Page - Donald E. Knuth, Stanford University
    From the author of The Art of Computer Programming. "Computer Musings" chronologically documents Knuth's informal lectures at Stanford. It also links to Musings Online, digitized versions of videos from the lecture series that included Dancing Links; The Joy of Asymptotics; Bubblesort at random (one-dimensional particle physics); Finding all spanning trees; Trees, Forests, and Polyominoes; and Mathematical Writing (1987). See, in particular, "The 'Aha' sessions," over 25 hours of graduate CS students tackling five previously unsolved programming problems in number theory, code-breaking (cryptagrams), high-speed chip testing, distributed control, and computer graphics (a self-portrait). "You could literally see the Aha taking place. People can watch the problem-solving process as it occurred." Frequently Asked Questions include "What's your favorite programming language?" and "Why do you pay $2.56 for every error found in your books?" and "Who will answer my questions about TeX?" Also, Knuth's recent news, preprints of recent papers, encapsulated PostScript graphics to download, and CWEB and other programs to download, featuring two demonstrations by different methods that exactly 2,432,932 knight's tours are unchanged by 180-degree rotation of the chessboard. more>>

  4. FOLDOC: Free On-line Dictionary of Computing - Denis Howe
    A searchable dictionary of acronyms, jargon, programming languages, tools, architectures, operating systems, networking, theory, mathematics, telecoms, institutions, companies, projects, products, history, in fact anything to do with computing - and broad enough to include a cross-section of mathematics topics. Also cross-references, links to other resources, and bibliographical information. more>>

  5. The Object-Oriented Numerics Page - Todd Veldhuizen
    Mailing lists; Free libraries of software for linear algebra, arrays and images, neural networks and genetic algorithms, multiprecision/exended exponent data types, differential equations, automatic differentiation and interval arithmetic, visualization, and misc. uses; Free tools; Commercial libraries and software; Related Projects; Reference material; Conferences; Related Web Indices; and a Bibliography. more>>
