RTC Quick Start becoming a book, now in beta

The Real-Time Communications (RTC) Quick Start Guide started off as a web site but has recently undergone bookification.

As of today, I'm calling this a beta release, although RTC is a moving target and even when a 1.0 release is confirmed, the book will continue to evolve.

An important aspect of this work is that the book needs to be freely and conveniently available to maximize participation in Free RTC. (This leads to the question of which free license should I choose?)

Lumicall's 3rd Birthday

Today, 6 February, is the third birthday of the Lumicall app for secure SIP on Android.

Happy birthday

Lumicall's 1.0 tag was created in the Git repository on this day in 2012. It was released to the Google Play store, known as the Android Market back then, while I was in Brussels, the day after FOSDEM.

Lumicall: big steps forward, help needed

I've recently made more updates to Lumicall, the free, open source and secure alternative to Viber and Skype.

Free and open WebRTC for the Fedora Community

In January 2014, we launched the rtc.debian.org service for the Debian community. An equivalent service has been in testing for the Fedora community at FedRTC.org.

Some key points about the Fedora service:

PostBooks 4.7 packages available, xTupleCon 2014 award

I recently updated the PostBooks packages in Debian and Ubuntu to version 4.7. This is the version that was released in Ubuntu 14.10 (Utopic Unicorn) and is part of the upcoming Debian 8 (jessie) release.

A URI prefix for radio callsigns

I've had my amateur callsign far longer than I've had my email address or provider-independent IP ranges.

While working with the tel: URI recently, I started thinking it would be useful to have a similar URI scheme for radio callsigns. After all, callsigns follow a well documented and globally unique pattern. Amateur operators are often mixing computing technology with radio. This could be a useful foundation for bigger things.

reConServer for easy SIP conferencing

In the lead up to the release of Debian wheezy, there was quite some debate about the Mumble conferencing software which uses the deprecated and unsupported CELT codec. Although Mumble has very recently added Opus support, it is still limited by the fact that it is a standalone solution without any support for distributed protocols like SIP or XMPP.

Best real-time communication (RTC / VoIP) softphone on the Linux desktop?

The Debian community has recently started discussing the way to choose the real-time communications (RTC/VoIP) desktop client for Debian 8 (jessie) users.

Google Summer of Code opportunities in JavaScript, HTML5, jQuery and WebRTC

WebRTC is one of the highlights of HTML5. The latest stable releases of Google Chrome (including the free Chromium browser) and Firefox include support for this technology and although the specifications are still being finalized, this is the time when developers can start preparing the first generation of web-apps that will define the future of this technology.
