Open Simulator

http://opensimulator.org/ from the site :

What is OpenSimulator?

OpenSimulator is an open source multi-platform, multi-user 3D application server. It can be used to create a virtual environment (or world) which can be accessed through a variety of clients, on multiple protocols. It also has an optional facility (the Hypergrid) to allow users to visit other OpenSimulator installations across the web from their ‘home’ OpenSimulator installation. In this way, it is the basis of a nascent distributed Metaverse.

OpenSimulator allows virtual world developers to customize their worlds using the technologies they feel work best – we’ve designed the framework to be easily extensible. OpenSimulator is written in C#, running both on Windows over the .NET Framework and on Unix-like machines over the Mono framework. The source code is released under a BSD License, a commercially friendly license to embed OpenSimulator in products. If you want to know about our development history, see History.

Out of the box, OpenSimulator can be used to simulate virtual environments similar to Second Life™, given that it supports the core of SL’s messaging protocol. As such, these virtual worlds can be accessed with the regular SL viewers. However, OpenSimulator does not aim to become a clone of the Second Life server platform. Rather, the project aims to enable innovative feature development for virtual environments and the Metaverse at large.

OpenSimulator is getting more stable over time but is still a high complex software system that can suffer various bugs and quirks; handle with care!

More to come…

Segments of a conversation…

Closed systems suffer from entropy where open systems do not. Closed collapse and Microsoft now can not out run the they have wrought  with the sonslaughteeds they have sown. This why the have changed their minds and how they are
aware that their days are numbered.


There is a level of openness with manufacturing of hardware. Which is why open compute. Open hardware is a better choice https://en.m.wikipedia.org/wiki/Open-source_computing_hardware

Bug Bounties can go bad…


Is an interesting article about one particular bug bounty.


Open Source SDFP (Sensory Development Flotation Pod)

http://truerest.com/  Is an example of a company that showcases Flotation Pods.

The R.E.S.T. Centre  is a Northern Ontario Flotation Therapy Centre.

Flotation therapy is an excellent tool to combine with mindfulness practices such as pranayama (breathing), Yoga, Qi gong, Tai Chi, and transcendental meditation. Using various techniques one may strengthen ones focus, and overall body awareness and health with regular flotation sessions.

Introducing flotation and meditation together will also extend the enjoyment of your flotation experience throughout your life.

Article: “Christoph Hellwig Continues VMware GPL Enforcement Suit in Germany”

https://sfconservancy.org/news/2015/oct/28/vmware-update/ (article excerpt below)

Christoph’s response discusses his extensive contributions to the Linux kernel and disputes the technical merits of VMware’s assertions. The response points out that vmklinux is not an interoperability module, but rather an arbitrary separation of the Linux derived module from vmkernel. Specifically, vmklinux is nonfunctional with any non-ESX OS, and vmklinux is tied intimately to a specific version of ESXi. Vmklinux does not allow reuse of unmodified Linux drivers in binary or source form. Christoph further points out that if the Court allows proprietarization of an arbitrary split portion of GPL’d computer programs, it could allow redistributors to trivially bypass the strong copyleft terms found in the GPL. Finally, the response explains that vmkernel and vmklinux don’t “communicate over an interface”, rather they run in the same process as a single computer program. Thus, VMK API, as used by vmklinux, is not an “interface” as set forth in the EU Directive 2009/24/EC.

And Germany also protects the individual citizens’ right to reverse engineer, as does Norway (1)


Asterisk – Open Source Telephony and Telecommunications


What is Asterisk?

Asterisk is an open source framework for building communications applications. Asterisk turns an ordinary computer into a communications server. Asterisk powers IP PBX systems, VoIP gateways, conference servers and other custom solutions. It is used by small businesses, large businesses, call centers, carriers and government agencies, worldwide. Asterisk is free and open source. Asterisk is sponsored by Digium.

Today, there are more than one million Asterisk-based communications systems in use, in more than 170 countries. Asterisk is used by almost the entire Fortune 1000 list of customers. Most often deployed by system integrators and developers, Asterisk can become the basis for a complete business phone system, or used to enhance or extend an existing system, or to bridge a gap between systems.
