Game Emulation In Linux Computer gaming is nothing new. Even in the earliest days of computing, we began to see an immediate desire to run games. In 1951, the NIMROD computer was built with the sole purpose of playing the game of NIM. Some twenty years later, we began to see growth of games on both PCs and consoles. The first known console was the Magnavox Odyssey, which used circuit cards for each game. Fast forward to the early eighties with the launch of the Atari 2600. So what am I getting at? What Is Emulation? Throughout this article, we will be taking a look at a variety of emulators that run on Linux. It seems simple, but there is no doubt that the coders behind these emulators work long and hard to create a stable program. Back to the story at hand. I am not an authority to decide what’s right and what’s wrong, and will also not be linking to any sites that host ROM files, just the emulators. Legalities aside, there is a vast selection of different emulators out there for you to choose from.
Netdisco - Network Management and Discovery VOIP Encryption There are basically four ways to eavesdrop on a telephone call. One, you can listen in on another phone extension. This is the method preferred by siblings everywhere. If you have the right access, it's the easiest. While it doesn't work for cell phones, cordless phones are vulnerable to a variant of this attack: A radio receiver set to the right frequency can act as another extension. Two, you can attach some eavesdropping equipment to the wire with a pair of alligator clips. Three, you can eavesdrop at the telephone switch. Four, you can tap the main trunk lines, eavesdrop on the microwave or satellite phone links, etc. That's basically the entire threat model for traditional phone calls. Unfortunately, phone calls from your computer are fundamentally different from phone calls from your telephone. And we already know the threat model for IP. It's comparable to threat No. 3 above, but with the scope vastly expanded. My greatest worry is the criminal attacks.
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. More information about accessing routing information via RIPEstat. For comments and feedback, please contact stat [at] ripe [dot] net.
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.

Greg's Jumbo Patches for John Bradley's XV Intro XV is John Bradley's shared-source, shareware image viewer for the X Window System. It has an outstanding user interface, an excellent suite of tools, and read/write support for a large number of image formats. Even grumpy editors like it. On the other hand, the last official release of XV was more than a decade ago, and as far as Greg has been able to determine, no part of the XV web site gets updated more frequently than once every two to four years.* There have been quite a number of third-party patches produced, and many of the older ones are even listed on the XV Downloads page. Unfortunately, many of them collide with each other, making their application much more of an experts-only process than it should be. *Even the bassets page, which used to get regular updates, went static in May 2006. What's Here The jumbo patch below incorporates roughly 131 fix- and enhancement-patches, most of which have been created by other people and are (or were) available as standalone patches.
Home page 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. 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 Each manuscript file is accessible through either of two indexes: 0. 1. EWD-numbered documents (This index gives an approximate correspondence between manuscripts’ EWD numbers and the year in which they appeared.) Summaries Revised
SIP.edu Cookbook : Introduction The Session Initiation Protocol (SIP), is a signaling protocol used for establishing voice, video, and instant messaging communications over the Internet. SIP has been widely adopted by telecommunications carriers and computer software vendors as a means to support next generation communications services. SIP standards are being developed within the Internet Engineering Task Force (IETF) SIP working group. The goals of the Internet2 SIP.edu project are to: Increase the number of SIP-reachable users within Internet2; Promote the convergence of voice and email identities; Build a community of Internet2 schools that is experimenting with offering enterprise SIP services. By becoming "SIP.edu-enabled", a school makes all of its telephones (and users) reachable via SIP. Once a school has deployed the initial SIP.edu architecture, it can begin to explore and implement other SIP-related services. This cookbook is intended for schools that are interested in implementing SIP.edu on their campuses.
