Hi, I'm on Ubuntu 18.10 and I've successfully installed nest to `/usr`.
I'm interested in writing my own synapse models and found these instructions for getting started: https://nest.github.io/nest-simulator/extension_modules
The configuration step, `cmake -Dwith-nest=/usr/bin/nest-config ../MyModule` works fine. However, when I ran `make` I received the following compiler error:
```
~/Projects/NEST/MyModule/mymodule.cpp: In member function ‘virtual void mynest::MyModule::init(SLIInterpreter*)’:
~/Projects/NEST/MyModule/mymodule.cpp:128:24: error: no matching function for call to ‘nest::ModelManager::register_connection_model<mynest::DropOddSpikeConnection<nest::TargetIdentifierPtrRport> >(const char [17])’

I am not sure how to deal with this, and any help would be appreciated. Thank you!
Dear all!
We are going to have a NEST issue review VC tomorrow morning (Friday 10 Jan 10-13 CET) in the usual VC room for developer VCs (https://github.com/nest/nest-simulator/wiki/Connection-Details). The main aim is to review open issues in preparation of the NEST 3 merge and (eventually) release.
Excuse the short notice, still booting up for 2020.
Best,
Hans Ekkehard

Dear NEST Users & Developers! Happy new year 2020!
I would like to invite you to this years first Open NEST Developer Video
Conference, tomorrow
Monday 6 January, 11.30-12.30 CET (UTC+1).
As usual the agenda for this meeting is also available online, see
https://github.com/nest/nest-simulator/wiki/2020-01-06-Open-NEST-Developer-…
For details how to log in see below.
Agenda
* Welcome
* Review of NEST User Mailing List
* Review of open Github Pull Request
* Review of open Github Issues
Looking forward to seeing you soon!
best,
Dennis Terhorst
------------------
Log-in information
------------------
We use a virtual conference room provided by DFN (Deutsches Forschungsnetz).
You can use the web client to connect. We however encourage everyone to
use a headset for better audio quality or even a proper video
conferencing system (see below) or software when available.
Web client
* Visit https://conf.dfn.de/webapp/conference/97938800
* Enter your name and allow your browser to use camera and microphone
* The conference does not need a PIN to join, just click join and you're in.
In case you see a dfnconf logo and the phrase "Auf den
Meetingveranstalter warten", just be patient, the meeting host needs to
join first (a voice will tell you).
VC system/software
How to log in with a video conferencing system, depends on you VC system
or software.
- Using the H.323 protocol (eg Polycom): vc.dfn.net##97938800 or
194.95.240.2##97938800
- Using the SIP protocol:97938800@vc.dfn.de
- By telephone: +49-30-200-97938800
For those who do not have a video conference system or suitable
software, Polycom provides a pretty good free app for iOS and Android,
so you can join from your tablet (Polycom RealPresence Mobile, available
from AppStore/PlayStore). Note that firewalls may interfere with
videoconferencing in various and sometimes confusing ways.
For more technical information on logging in from various VC systems,
please see
http://vcc.zih.tu-dresden.de/index.php?linkid=1.1.3.4
Dear NEST Developers!
Best of seasons greetings to everyone! Since many people will not be
available today we will skip the video conference. Our next regular
meeting will be on January 6th.
Merry Christmas to everyone! Enjoy the last days of 2019 and have a nice
new-years!
Looking forward to seeing all of you again in 2020!
best,
Dennis Terhorst

Dear NEST Users,
We are happy to announce that the NEST Conference 2020 will again be held on NMBU's beautiful campus in Ås, Norway on
29 / 30 June 2020
followed by a NEST Hackathon until 3 July. More information will follow in a few weeks.
Save the date & see you in the summer!

Dear simulation enthusiasts,
The group in Pavia is preparing an event around CEREBELLUM MODELLING, in which you can see NEST and other simulators put to use on larger scale. It will be a nice occasion to meet with many other users, exchange experience and learn about model construction. Egidio, Claudia, Simona and team are organising this as a hackathon:
Hackathon on CEREBELLUM MODELLING
13-15 January 2020, in Pavia.
If you are interested in joining, please drop Simona Tritto an email:simona.tritto@unipv.it<mailto:simona.tritto@unipv.it>
You can find the program attached.
best,
Dennis

Hi all,
I am currently using nest.ResetNetwork() with to_file option and when I
reset the network, seemingly it also deletes everything recorded so far by
connected probes (spike detector, for instance).
Any suggestions on how to avoid the deletion of previously written data on
files.

Dear all,
I have two questions that arise when implementing my adapted C++ synapse
model.
1) Postsynaptic spikes have a "multiplicity" variable. Am I correct that
if I receive a single spike object with a multiplicity value of 3, I
actually receive 3 spikes? Since I do only get one time, what are the
exact spike times of the other spikes?
2) For the postsynaptic spikes I can easily access the spike history and
search for spikes in a certain time range, as for example done in the
STDP synapse. Is it possible to also access the overall spike history of
presynaptic spikes? So far I only found that in the std_dopamine synapse
as an example the last spike time is stored manually.
Thank you very much !
Best Regards,
Benedikt Feldotto

Dear NEST Developers!
On Monday there will be no Open NEST Developer Video Conference, since
many of the NEST users and developers are traveling at that time to join
the HBP CodeJam#10 and adjoined events.
As usual, if you would have something you want to add to the agenda,
please don't hesitate to contact me anyway. I will then add it in the
the following meeting.
Looking forward to seeing you soon!
best,
Dennis Terhorst
