Solution stack In computing, a solution stack is a set of software subsystems or components needed to perform a task without further external dependencies. For example, to develop a web application, the designer needs to use an operating system, web server, database, and programming language. Another version of a solution stack is operating system, middleware, database, and applications.[1] Linux-based solution stacks[edit] Linux (the operating system) Apache (the web server) MySQL or MariaDB (the database management systems) Linux (operating system) Apache (web server) Seaside (web framework) Smalltalk (programming language) The cloud stack of LEAP for: AppScale (Cloud computing-framework and free and open-source alternative to Google App Engine), OpenStack Linux – OpenStack controller nodes run exclusively on Linux OpenStack – providing an infrastructure as a service (IaaS) Ganeti Xen or KVM (hypervisor) Distributed Replicated Block Device (storage replication) Ganeti (virtual machine cluster management tool) Node.js
List of photo sharing websites This is a non-exhaustive list of major photo-sharing websites. Active photo-sharing websites[edit] Defunct photo-sharing websites[edit] These also include sites that may still operate, but do not accept new users. Listed in chronological order of shutdown. Comparison of photo-sharing websites[edit] Legend: References[edit] Yaws (web server) Because Yaws uses Erlang's lightweight threading system, it performs well under high concurrency. A load test conducted in 2002 comparing Yaws and Apache found that with the hardware tested, Apache 2.0.39 with the worker MPM failed at 4,000 concurrent connections, while Yaws continued functioning with over 80,000 concurrent connections.[2] Official websiteInterview with YAWS developer Claes Klacke Wikstrom (OGG or MP3)ErlyWeb – MVC-pattern web framework for YawsErlang Web – MVC-pattern web framework Yaws and Inets Erlang/OTP applicationNitrogen – An event-driven Web 2.0 framework for Erlang that runs on Yaws, Mochiweb, and Inets
Unshake How to Use Unshake. How to Install. Unshake 1.5 is a Java-2 and C program which improves blurred and shaken photographs by working out the form of the blurring, then deducing what the picture would have looked like if it had not been blurred. Also included in this distribution is a library and command-line filter for Linux, UnshakeC1.5r1. Unshake is offered free for personal use. This is an example of what it can do; Below is a small part of a picture I took with a cheap Polaroid camera, blown up to 600 dpi. Unshake can also remove dithering and rasters, and it can work through the lines found on magazine pictures, though for copyright reasons I can't put examples of Unshaken magazine pictures on the website. But the real point of Unshake is that it does it automatically. For more examples, click here... or here Installation To install Unshake, please see "Installing Unshake".
Amateur radio An example of an amateur radio station with four transceivers, amplifiers, and a computer for logging and for digital modes. On the wall are examples of various awards, certificates, and a reception report card (QSL card) from a foreign amateur station. Amateur radio (also called ham radio) is the use of designated radio frequency spectra for purposes of private recreation, non-commercial exchange of messages, wireless experimentation, self-training, and emergency communication. The amateur radio service (amateur service and amateur satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. Amateur radio is officially represented and coordinated by the International Amateur Radio Union (IARU), which is organized in three regions and has as its members the national amateur radio societies which exist in most countries. History[edit] An amateur radio station in the United Kingdom. Ham radio[edit]
Géolocalisation Un article de Wikipédia, l'encyclopédie libre. Schéma de principe de la géolocalisation par GPS La géolocalisation ou géoréférencement est un procédé permettant de positionner un objet (une personne, etc) sur un plan ou une carte à l'aide de ses coordonnées géographiques. Cette opération est réalisée à l'aide d'un terminal capable d'être localisé (grâce à un système de positionnement par satellites (et un récepteur GPS par exemple) ou à d'autres techniques) et de publier (en temps réel ou de façon différée) ses coordonnées géographiques (latitude/longitude). Techniques de géolocalisation[modifier | modifier le code] Géolocalisation par géocodeur[modifier | modifier le code] Les logiciels de géocodage permettent de calculer et d'attribuer à une adresse ou à un objet référencé dans une carte vecteur des positions X,Y avec une précision de quelques dizaines de mètres en moyenne.

Simple Authentication and Security Layer Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols, in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL. Authentication mechanisms can also support proxy authorization, a facility allowing one user to assume the identity of another. SASL is an IETF Standard Track protocol and is, as of 2010[update], a Proposed Standard. SASL mechanisms[edit] A SASL mechanism implements a series of challenges and responses. "EXTERNAL", where authentication is implicit in the context (e.g., for protocols already using IPsec or TLS)"ANONYMOUS", for unauthenticated guest access"PLAIN", a simple cleartext password mechanism." The GS2 family of mechanisms supports arbitrary GSS-API mechanisms in SASL.[5] It is now standardized as RFC 5801. SASL-aware application protocols[edit] See also[edit] References[edit]
Olympus E-510 Evolt digital camera online resource First impressions are very favourable. The IS gains about 2-3 stops, I really do not know how to measure this other than trying it out. I use the 50-200 Olympus lens and the Sigma 50-500 a lot and often need to hand hold. I understand that the remote issue with the E-500 is now resolved as the E-510 will use the same cable as the E-410 the RM-UC1. Some controls have been moved and I prefer the layout. The battery charger supplied is the BCM-2 which is disappointing as it charges the standard BLM-1 battery in about 4 hours, so keep your older BCM-1 as this does it in about 2 Hours.
ScreenPlay The MediaWiki ScreenPlay Extension (ScreenPlay) is a text-formatting add-on which allows screenwriters and hobbyists the ability to use MediaWiki as a screenwriting tool. Synopsis[edit | edit source] <screenplay>An example is described</screenplay><scene int day>A '''Darkened''' Room</scene> [[Bob Ross|BOB]] sits in front of a computer screen. ;bob :Hello friends, I'm so glad you could join us. We're gonna make a happy little program today. ;voice :(offstage) :Oh goodie! Will produce the following type of formatting: Note how word case has been adjusted in certain cases. Description[edit | edit source] ScreenPlay supports three new editing hooks to add style codes that visually re-format certain wiki syntax (specifically, those used for definition lists, or "dl's") into proper screenplay format. Though ScreenPlay is not a replacement for a full-featured ScreenWriting software package, it offers a number of advantages for screenwriters: Usage[edit | edit source] Hooks[edit | edit source]
Alternative DNS root The Internet uses the Domain Name System (DNS) to associate numeric computer IP addresses with human readable names. The top level of the domain name hierarchy, the DNS root, contains the top-level domains that appear as the suffixes of all Internet domain names. The official DNS root is administered by the Internet Corporation for Assigned Names and Numbers (ICANN). The Internet Architecture Board (IAB) has spoken out strongly against alternate roots in RFC 2826.[1] Description[edit] The DNS root zone consists of pointers to the authoritative domain name servers for all TLDs (top-level domains). Alternative DNS roots may be characterized broadly as those run for idealistic or ideological reasons, run as profit-making enterprises, and those run internally by an organization for its own use. While technically trivial to set up, the maintenance of a reliable root server network is a serious undertaking. List of alternative roots[edit] This section lists the known alternate DNS roots.

Freenet History[edit] The origin of Freenet can be traced to Ian Clarke's student project at the University of Edinburgh, which he completed as a graduation requirement in the Summer of 1999.[9][10][11] Ian Clarke's resulting unpublished report "A distributed decentralized information storage and retrieval system" (1999) provided foundation for the seminal paper written in collaboration with other researchers, "Freenet: A Distributed Anonymous Information Storage and Retrieval System" (2001).[12][13] According to CiteSeer, it became one of the most frequently cited computer science articles in 2002.[14] The distributed data store of Freenet is used by many third-party programs and plugins to provide microblogging and media sharing,[16] anonymous, decentralised version tracking,[17] blogging,[18] a generic web of trust for decentralized spam resistance,[19] Shoeshop for using Freenet over Sneakernet,[20] and many more.
