So what is computes.io? The latest Chris Matthieu vision after  30 years of experience in driving the development and launch of disruptive technologies. Prior to co-founding Octoblu, Chris was founder of Nodester, an open-source Node.JS PaaS which was acquired by AppFog and the founder of Teleku, a communications-as-a-service cloud platform which was acquired by Voxeo. Chris was also the founder of Digital Voice Technologies, the creator of the first VoiceXML-powered voice browser, which was acquired by Ideas & Associates.

We talk about Randy’s life and career in music, the VUC, how it began, where it’s going.

Born in Minneapolis, he gave George Harrison a guitar in 1965. A musician playing in bars into the late 1960’s, he moved to Los Angeles in the early 1970’s and went on to play with John Mayall and other famous musicians before moving to France in 1981.

The vision: The VUC began in 2007 as Asterisk Users Conference. Today, we’re focusing on the human side of technology, the visions rather than the products.

As most of VUC regulars will recognize the name Paul Vixie as the American computer scientist whose technical contributions include Domain Name System (DNS) protocol design and procedure, mechanisms to achieve operational robustness of DNS implementations, and significant contributions to open source software principles and methodology. He also created and launched the first successful commercial anti-spam service.

Topic: The Robustness Principle is Precisely Wrong

Fail fast and fail early, are the lessons of growth. Yet when it comes to Internet protocols we are advised to “be conservative in what you generate, and liberal in what you accept”. How can we reconcile these? By incinerating one, that’s how. Examples will include thickwire ethernet and IP fragmentation.

We’re honored to have Dr. Vixie back as a guest after last year’s session on DNS Response Policy Zone.

Here’s how Daniel Stenberg, author and maintainer of cURL and libcurl, describes himself:

“I write open source and free software. I work on open standards. I write open documents.”

An internet protocol geek, an open source person and a hacker, Daniel has been programming for fun and profit since 1985. You’ll find lots of info about his various projects on these web pages. He’s not kidding about open documents, he offers his book, Everything curl for download… free, of course.

We’re very pleased to have Daniel as a guest, and I hope if you have questions or just want to thank him for curl, you’ll join us on IRC (#vuc on Freenode) or post questions or comments on our Mastodon instance masto.vuc.me.

Key points: Open Architecture Video Platform Streaming 4K @ 30 uFPS – 1080 @60 uFPS
Rich tells us they’re in the final days of production engineering. The first panel build, color substitution and auto function parameter control, SFP+ modules all loom close. Presale is now open.

I wanted to add some detail so this becomes more than just a stub post, but an actual reference to generate questions, perhaps.

SFP+ Modules
At the foundation of SUB2r is the ability to configure the camera in as many ways as possible.  The most recent addition has been, removing the RJ45 Ethernet connector for an network SFP+ cage.  This allows the user to pick a hot swappable module and select SDI, HDMI, GigE, Optical as secondary outputs.

Color Substitution
Mention green screen and you elicit a painful rolling of the eyes and an audible groan.  They can be expensive, hard to evenly light and hog the CPU.  Because SUB2r has control over the color space, Igor derived a way to perform on camera color substitution.  Basically taking any background range of color and replacing it with anything else, in this case a pure RGB green.  They developed the algorithm, wrote the code, updated and debugged the firmware, wrote and debugged the UI in less than 2 weeks with 1 coder and 1 hardware engineer – part time.  The team live streamed at TwitchCon, turning almost any background into perfect green screens.

Denver Gingerich is developing an open source cellular network named Sopranica. The JMP component of Soprani.ca gives users a real phone number that can send and receive calls and text and picture messages over the Internet, using the client software of your choice. For example, text and picture message are sent with an XMPP client.

One popular XMPP app is Conversations (above right), which offers three encryption options for messages, including PGP. For voice communication, a SIP client can be used with JMP, which provides phone numbers to anonymous requesters. The SIP app above at left is Zoiper. (Zoiper was a VUC guest a few weeks ago.)

The assigned phone number, with a one month free trial, is used with the SIP client, again chosen by the user, to make and receive calls, while the XMPP client is used for text and picture messages. The most interesting element of Soprani.ca will be the radio that sets up an actual private network – this component is called WOM, and will allow you to use JMP even when outside wifi or cellular coverage, thanks to community-run gateway nodes.
