[2018-11-08] FreeSWITCH: Open Source Telecom – Asterisk

FreeSWITCH is a scalable open source cross-platform telephony platform designed to route and interconnect popular communication protocols using audio, video, text or any other form of media. It was created in 2006 to fill the void left by proprietary commercial solutions. FreeSWITCH also provides a stable telephony platform on which many applications can be developed using a wide range of free tools.FreeSWITCH was originally designed and implemented by Anthony Minessale II with the help of Brian West and Michael Jerris. All 3 are former developers of the popular Asterisk open source PBX. The project was initiated to focus on several design goals including modularity, cross-platform support, scalability and stability. Today, many more developers and users contribute to the project on a daily basis and we support interop with Asterisk over SIP.FreeSWITCH can perform full video transcoding and MCU functionality using its conferencing module. FreeSWITCH supports many advanced SIP features such as presence/BLF/SLA as well as TCP TLS and sRTP. It also can be used as a transparent proxy with and without media in the path to act as a SBC (session border controller) and proxy T.38 and other end to end protocols. FreeSWITCH supports both wide and narrow band codecs making it an ideal solution to bridge legacy devices to the future. The voice channels and the conference bridge module all can operate at 8, 12, 16, 24, 32 or 48 kilohertz in mono or stereo and can bridge channels of different rates. The G.729 codec is also available under a commercial license. FreeSWITCH builds natively and runs standalone on several operating systems including Windows, Max OS X, Linux, BSD and Solaris on both 32 and 64 bit platforms. FreeSWITCH supports FAX, both over audio and T.38, and can gateway between the two.

“The Use of Knowledge in Society” – Econlib

What is the problem we wish to solve when we try to construct a rational economic order? On certain familiar assumptions the answer is simple enough.

If we possess all the relevant information,
if we can start out from a given system of preferences, and
if we command complete knowledge of available means, the problem which remains is purely one of logic. That is, the answer to the question of what is the best use of the available means is implicit in our assumptions. The conditions which the solution of this optimum problem must satisfy have been fully worked out and can be stated best in mathematical form: put at their briefest, they are that the marginal rates of substitution between any two commodities or factors must be the same in all their different uses.

[2015-09-16] Hayek on the Use of Knowledge in Society – MRU

This video discusses Friedrich Hayek’s most famous essay titled “The Use of Knowledge in Society.” This essay first appeared in the American Economic Review in 1945 and focused on the division of knowledge in society. Hayek uses the example of the tin market to illustrate how prices communicate relevant information. If there is a disruption in the tin market, individuals don’t need to know specifics about the disruption, just that the price for tin is higher. As the price increases, individuals economize or look for substitutes. In this sense, no one plans prices or markets, rather it is the result of spontaneous order. Entrepreneurs seek profits and consumers seek to maximize their utility, which bring about the use and mobilization of decentralized knowledge.
