Subject: OsmoDevCon 2022 ?
Message-ID: <YYEEG5iH/7FxvHLc@nataraja>

Dear fellow Osmocom developers,

as you all know, we've sadly had to skip OsmoDevCon 2020 and 2021,
trying to compensate it at least to some extent with our OsmoDevCall
every two weeks.

The COVID-19 pandemic is far from over, and we don't know what the
upcoming winter season will bring.

Nevertheless, I think it would be a good idea to start a discussion of
whether we should plan for an OsmoDevCon in 2022.

I personally would say let's plan for the usual late April 2022 time frame,
and if the pandemic situation deteriorates, we can still cancel it with
something like one month lead time.

I would also personally suggest to limit attendance to people who are fully
vaccinated, and in addition do a self-test for all participants every
morning.

In terms of venue, we might also consider to move to a venue that allows better
ventilation.  Irrespective of the above we can also bring the air filters from
the sysmocom office.

So with that as an input statement, I would like to hear your opinion
on the above proposals.  Who would want to attend? Any complaints against
the "vaccinated only plus daily self-tests in the morning" approach?

Regards,
	Harald

Hi Harald,

I'm definitely for it and would attend and the usual timeframe sounds good.

As for the modalities.
 - Vaccinated : Sure.
 - Self Test : Although a test before departure sounds like a good
idea, I'm not really sure of the need / efficacy of a day to day test.
But I also have no issue taking one if people are more comfortable
that way or think it's worth it.
 - Venue : Obvious questions is what are the alternatives :)
 - Ventilation : I honestly have no idea on the efficacy of that, but
if you got filters for the sysmocom office, I guess you did some
research and if they are movable and not obnoxiously loud, that can't
hurt.
 - Masks : You didn't mention it in your original email, but
personally I think in this context ( low number of people, but quite
extended period of time, + meals / drinks ), their efficacy would be
negligible. But again, if the consensus is to wear them, I have no
issues with that.

This is of course just my 2ct and also for my personal situation (like
for instance I know I can easily have a week "buffer" before/after the
event where I'll have virtually no contacts).
Looking forward to hear what others think.

Cheers,

    Sylvain

What am I missing here? I installed the required RTL-SDR packages too!

PFA CMake files

How did you install gnuradio - with the package manager or from source?

Which gr-osmosdr version are you trying to install?

This error indicates you are trying to install an older version that is compatible with gnuradio 3.7 but not with 3.8

> What am I missing here? I installed the required RTL-SDR packages too!

For gnuradio 3.8 you need to build the latest version of gr3.8 branch [1] or version 0.2.3 [2]. In case you have install gnuradio from the Ubuntu's repository you can install gr-osmosdr from there as well - sudo apt-get install gr-osmosdr
