The Manuscripts Like most of us, Dijkstra always believed it a scientist’s duty to maintain a lively correspondence with his scientific colleagues. To a greater extent than most of us, he put that conviction into practice. For over four decades, he mailed copies of his consecutively numbered technical notes, trip reports, insightful observations, and pungent commentaries, known collectively as “EWDs”, to several dozen recipients in academia and industry. Thanks to the ubiquity of the photocopier and the wide interest in Dijkstra’s writings, the informal circulation of many of the EWDs eventually reached into the thousands. Although most of Dijkstra’s publications began life as EWD manuscripts, the great majority of his manuscripts remain unpublished. The original manuscripts, along with diaries, correspondence, photographs, and other papers, are housed at The Center for American History of The University of Texas at Austin. Indexes 0. 1.

Ishac Bertran sent us details about his latest project - Code and Poetry: Lately I’ve been sketching an experimental project about Code and Poetry. This two terms have been connected for many reasons – I thought it would be interesting to explore the most literal meaning of it, using code to write traditional poetry. Code has many layers of abstraction that normal language doesn’t have, and I hope this can provide a new angle to contemporary poetry. Poetry written with code meant to be read in a book, not run in a computer. Ishac will be collecting code poems from people interested in contributing. You can find more information about the project on the website: {poems} is a project by Ishac Bertran

Biology's Next Revolution from Nature | Wanderings This looks fascinating. I tried clipping quotes but ended up highlighting practically the entire article. For evolutionary minded people, this is a fascinating development in thought, in theory. Definitely need to digest and describe. Biology's next revolution If link dies, read cached copy below. Nature 445, 369 (25 January 2007) | doi:10.1038/445369a; Published online 24 January 2007 Connections Biology's next revolution Nigel Goldenfeld1 and Carl Woese2 1. Abstract The emerging picture of microbes as gene-swapping collectives demands a revision of such concepts as organism, species and evolution itself. One of the most fundamental patterns of scientific discovery is the revolution in thought that accompanies a new body of data. Similarly, the convergence of fresh theoretical ideas in evolution and the coming avalanche of genomic data will profoundly alter our understanding of the biosphere — and is likely to lead to revision of concepts such as species, organism and evolution.

C Craft - Chapter&1.&Introduction C is the desert island language. This is my favourite statement from a talk Rob Pike gave in 2001. Despite its age, despite many flaws, C is still the de facto standard, the lingua franca. Why? Or as Linus Torvalds puts it, “C is the only sane choice”. One of C’s designers, Dennis Ritchie, gives a modest account of the evolution of C. The canonical reference, Kernighan and Ritchie’s "The C Programming Language" is slim, yet contains much more than the language specification. Not only is C easy for humans to understand, but machines too can pick up the language quickly. I can roughly envision the assembly generated by a C statement, so I can make educated guesses about time and space efficiency. Brevity is the soul of wit. In my Eiffel days, I was encouraged to write "integer", not "int", "character", not "char", and so on. We call friends by shortened versions of their names. C possesses elementary yet powerful constructs that are missing from other languages.

Zythom - Blog d'un expert judiciaire s Introduction to Complex Systems - StumbleUpon by David Kirshbaum I. Introduction: Complex Systems Theory : Basic Definition II. III. I. A Complex System is any system which involves a number of elements, arranged in structure(s) which can exist on many scales. Previously, when studying a subject, researchers tended to use a reductionist approach which attempted to summarize the dynamics, processes, and change that occurred in terms of lowest common denominators and the simplest, yet most widely provable and applicable elegant explanations. But since the advent of powerful computers which can handle huge amounts of data, researchers can now study the complexity of factors involved in a subject and see what insights that complexity yields without simplification or reduction. Scientists are finding that complexity itself is often characterized by a number of important characteristics: (II.1) Self-Organization(II.2) Non-Linearity(II.3) Order/Chaos Dynamic(II.4) Emergent Properties. (II.1) Self-Organization Examples (II.2) Non-Linearity

Les accords de Peering ou comment le Sud finance le Nord Mots-clés :afrique, internet, peeringCe document est le compte rendu de Cécile Méadel de la présentation que j'ai faite le 24 décembre 2006 pour Vox Internet. Internet a été conçu comme une architecture en pair à pair, reliant directement les réseaux des utilisateurs en passant par les réseaux d’autres utilisateurs (le plus souvent des universités et des centres de recherche au début). L’innovation majeure a consistée à proposer des protocoles standards pour réaliser un " réseau de réseaux " Mais avec l’augmentation exponentielle du nombre d’utilisateurs, et tout particulièrement l’utilisation du réseau téléphonique préexistant comme extension de l’Internet, des sociétés se sont montées avec comme seul but de servir d’intermédiaire pour interconnecter les utilisateurs et interconnecter les réseaux 1 La hiérarchisation de l'internet en trois niveaux Aujourd’hui, l’architecture de l’internet a des niveaux hiérarchisés différents Il y a trois manières d'interconnecter des réseaux.

Projects - RIS The RIPE NCC collects and stores Internet routing data from several locations around the globe, using the Routing Information Service (RIS), established in 2001. RIS data can be accessed via RIPEstat, our “one-stop shop” for all available information about Internet number resources. RIPEstat uses individual widgets to display routing and other information. Routing information is visualised using the following widgets: If you are interested in the location of RIS route collectors, and the list of peers, raw data or any other additional services based on RIS, please see the links on the sidebar.
