  1. Description. "FreeSWITCH is an open source telephony platform designed to facilitate the creation of voice and chat driven products scaling from a soft-phone up to a soft-switch. It can be used as a simple switching engine, a PBX, a media gateway or a media server to host IVR applications using simple scripts or XML to control the callflow.

    1. "Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

    Excerpts from the FAQ: How can I get an Arduino board? You can buy an Arduino board from one of the distributors listed on the buy page. If you'd prefer to build your own, see the Arduino Single-Sided Serial board, which can be easily etched and assembled. Who makes Arduino boards? Most of the official Arduino boards are manufactured by SmartProjec...

    1. Stefano De Paolia; Cristiano Storni: "The Arduino was initially designed for teaching purposes in a well-knowndesign institute in Italy. As one of the main three original developers of theboard recalled in an interview: - We already worked with Processing a lot. At that time Processing was limited tographical animation. Basically students used i...

    Technical

    "The Arduino prototyping platform is a good example of all this. It can be programmed to read sensors, control motors and build interactive objects and artistic installations. Its compiling environment is multiplatform and free (as in freedom) and the only extra hardware needed for programming it is a serial/ USB cable. This software can be downloaded from the website Arduino web site, which also contains Arduino schematics released under Creative Commons Attibution-ShareAlike. The project ha...

    Regarding Google choosing the open source hardware platform (Arduino) for the “Android Open Accessory” kit, by Phillip Torrone, May 12, 2011: "Besides there being about 300,000+ Arduino “in the wild,” I estimate there are about half a million people somehow doing something with the Arduino, from students to people not even realizing they’re using this open platform in some way (Processing, education, etc). For a microcontroller platform, as I’ve said before, it’s won and it’s here to stay. Co...

    Is Arduino Open Source?

    Arduino has a trademarked name (http://arduino.cc/en/Main/FAQ), but: Is Arduino open-source? "Yes. The source code for the Java environment is released under the GPL, the C/C++ microcontroller libraries under the LGPL, and the schematics and CAD files under Creative Commons Attribution Share- Alike licenses. I want to design my own board; what should I do? The reference designs for the Arduino boards are available from the hardware page. They’re licensed under a Creative Commons Attribution S...

    What do you mean by open-source hardware?

    "Open-source hardware shares much of the principles and approach of free and open-source software. In particular, we believe that people should be able to study our hardware to understand how it works, make changes to it, and share those changes. To facilitate this, we release all of the original design files (Eagle CAD) for the Arduino hardware. These files are licensed under a Creative Commons Attribution Share-Alike license, which allows for both personal and commercial derivative works, a...

    Five Reasons why Arduino is popular

    Wired: (By Priya Ganapati, July 6, 2010) Here are five reasons why the Arduino is more popular than the BeagleBoard: Starter Projects Editing and rewriting is often easier than writing from scratch. It’s the same with electronics. It’s easier to mod an idea than start with a blank slate. That’s where the BeagleBoard falls short. “It has virtually no example application that you can just copy and hack to learn from,” says Massimo Banzi, one of the co-founders of the Arduino project. The Arduin...

    A really really open Arduino? The Brasuíno-Holoscópio

    "Brasuíno BS1 is a single board microcontroller inspired on Arduino that uses the AVR microcontroller. This Brazillian version was redesigned using Libre Software, free to reuse and derive, and it's licensed as GPLv2+ (the original Arduino still uses a microchip that is not open hardware). It's also compatible with Arduino Uno and Arduino software."(http://www.furtherfield.org/features/reviews/celebrating-brazilian-open-digital-culture-festival-cultura-digital)

  2. Different applications of P2P networks enable users to share the computation power (distributed systems), data (file-sharing), and bandwidth (using many nodes for transferring data). P2P uses an individual's computer power and resources, instead of powerful centralized servers. The shared resources guarantee high availability among peers."

  3. Removing switch, server, installation, maintenance and support costs can lower communications system TCO (total costs of ownership) by up to 80%. Call establishment delay and other critical issues are minimized by a system that can seamlessly adapt to new users and services.

  4. Distributed computing is a type of segmented or parallel computing, but the latter term is most commonly used to refer to processing in which different parts of a program run simultaneously on two or more processors that are part of the same computer." Distributed computing has begun developing in the research area for solving simulation or ...

  5. It’s a bait-and-switch, wrapping the same old lock-in in the flag of open source and hoping you won’t notice. This is not just a philosophical game. “Software freedom” may sound abstract, but it is the system of thinking behind the very practical and tangible benefits that have drawn vast numbers of businesses to use open source.

  6. 2018年6月17日 · Switched point-to-point topologies are the basic model of conventional telephony. The value of a permanent point-to-point network is the value of guaranteed, or nearly so, communications between the two endpoints. The value of an on-demand point-to-point connection is proportional to the number of potential pairs of subscribers, and has been ...
