Participating

For this year’s hybrid event, we will have in-person and virtual attendees, talks (pre-recorded), and workshops. All of the talks are being live-streamed publicly to YouTube. Visit the GNU Radio YouTube channel and you can set reminders to be notified when each day’s stream is starting, see Main Track Talks below for a link to each day's livestream.

In-Person

Additional details can be found in the In-Person Venue section on the GRCon21 website which also includes a venue layout.  In-person participants are also encouraged to join in on virtual events and activities like Matrix chat.

Virtual

Virtual attendees will have access to our livestreams and Matrix chat for Free.  Additional access to Virtual Workshops is available for those who purchase an “Online Workshop Pass” here. There will be various GNU Radio leads and core devs hanging around the chat channels, ready to answer questions or discuss a topic, see Chat Rooms for more info.

Additional details can be found in the Virtual Event section on the GRCon21 website.

Main Track Talks

The virtual portion of questions and answers for each talk will happen on in the conference Chat Rooms, specifically in the #grcon21-talks room. Register ahead of time and join this channel while watching to see and participate in the discussions.

Chat Rooms

Much of the value of the GNU Radio Conference is in the interactions between all participants of the event. In moving to include virtual participation one of our core focuses was on supporting these interactions as much as possible.

The conference will make heavy use of the “Matrix” chat system which is used year-round for GNU Radio development and community discussions. There are rooms for general chat, discussions and Q&A for main track talks, individual sponsors, and topical breakouts.

https://chat.gnuradio.org

We strongly recommend that you join in the chat where possible.

Once you have logged in you should see the main GRCon discussion page. The full list of GRCon rooms are located at:

https://chat.gnuradio.org/#/room/#grcon21:gnuradio.org

The GNU Radio Code of Conduct also applies to GRCon Chat Rooms.

Chat Sign-up

Go to https://chat.gnuradio.org and create a new Account. No information other than username and password are required, though an email address is helpful for password recovery.

Matrix does support chat encryption and will ask you to make a backup of your private key information in case you lose access to your existing login.


Chat Clients

A pretty comprehensive list of clients can be found here along with comparison charts here.  

Many current members of the GNU Radio Chat community have mentioned the phone apps are a quick and easy way to communicate, as well as the web-app client that https://chat.gnuradio.org brings you to.

The homeserver of the GNU Radio Chat is https://gnuradio.ems.host.  See below for an example of how to create an account using the GNU Radio homeserver on the Element Desktop Client (to sign-in you click “Sign in instead”).

Conference Chat Rooms

We have several chat rooms setup for interaction during GRCon.  All chat rooms will be monitored/moderated during the event.  Many chat rooms will remain active until 1 week after the conference, and some will persist beyond the conference.

Main Chat Rooms

We will host the following chat rooms during GRCon.  In addition, each sponsor will have a separate chat room, see below for more information.

The easiest way to see all the rooms is to visit https://chat.gnuradio.org/#/room/#grcon21:gnuradio.org

Chat/Matrix FAQ

How can I log into my account in a second browser?

The GNU Radio chat includes strong encryption between users (disabled on the public channels). When you first log into your account on a second computer or browser the website/app will prompt you to verify your login using another verified session. Here is a video demonstrating the process:

https://www.youtube.com/watch?v=9ZUWmGQrbBQ

How can I talk directly with someone?

A direct message can be sent to a user by searching for them under “People”.

How to join Rooms?

For the GRCon specific rooms, the rooms are listed on the main GRCon Community page[1] after the description or on the side panel using # icon:

Other Questions

A #grcon21-helpdesk channel has been set up as a way of quickly addressing any questions, concerns, or suggestions you may have during the event. Several conference organizers and volunteers will be monitoring that channel during the event.

Workshops

GRCon21 is offering in-person, virtual, and hybrid (in-person and virtual) workshops this year.  Please see the listing of workshops on the events site for more details.

This is our first year doing both in-person and virtual workshops.  We expect a few issues to arise and appreciate your patience and understanding as we work through this process.

Virtual Workshops

Most virtual workshops will be conducted via Big Blue Button,  an open source web conferencing system for online learning.  Links will be provided to attendees who sign-up prior to the workshop’s start.

To ensure that Q&A is possible and that the virtual workshop platform gives a good experience, each workshop is currently limited to 100 attendees (except the OpenCPI talks which are limited to 20 due to hardware limits). Waitlists are enabled and we will be tracking demand for each workshop.

You can preview the workshop platform and check that it works for you at http://test.bigbluebutton.org

Obtaining Workshop BBB Links

All in-person attendees and virtual attendees who purchased an “Online Workshop Pass” will receive links to attend the virtual workshops.

The process has been simplified.  The links provided will give you access to any of the workshops.  We are not planning to limit virtual attendance as we believe BBB will handle our expected participant numbers.


Frequently Asked Questions

How do I ask a question to the presenter?

Join the #grcon21-talks chat room on Matrix. Presenters will be in this room during their talk to answer questions in real-time.

Will the talks be recorded?

Yes, all the talks will be available on the GNU Radio YouTube channel after the conference.

Will the slides be available?

Slides are being collected and will be posted onto the conference website after the event. Unfortunately we don’t have them in-place during the event.

Will Workshops be recorded and available?

It's up to the individual workshop instructors if they would like to share a recording of their workshop.  If the workshops recordings are shared they will be publicly accessible.

How do I ask for help?

For real-time assistance during conference hours please feel free to stop by the GRCon Registration Desk (In-Person) or GRCon Help Desk Chat room on chat.gnuradio.org (Virtual).  Another option is email, but responses may be slower.

GRCon Help Desk Chat Room: https://chat.gnuradio.org/#/room/#grcon21-helpdesk:gnuradio.org

If you have a specific question or comment you can use @organizers in your chat to alert the organizers to your message.
