PyData Skopje meetup January 2020

Welcome at the January 2020 PyData Meetup in Skopje. Giving the talk will be Branislav Gerazov, PhD, professor at FEIT, and generally cool guy.

Abstract of the talk: The annotation of intonation contours is a tedious task in which it is often hard to make precise classification of the contour type. This is due to the large level of acceptable variability in the melody whilst allowing for correct transfer of the intended linguistic and paralinguistic information, superimposed on the innate nonlinguistic variation. To ease the process, we designed a tool for interactive annotation in the form of a web application. The tool is based on an interactive plot of the intonation contours whose distribution is based on their similarity extracted with a variational autoencoder. The tool can be used to visually and acoustically inspect the contours and utterances, and for their classification. The whole system is realised in Python with the use of the Bokeh visualisation library (https://bokeh.org/) and the Django web framework (https://www.djangoproject.com/).

This work was carried out in collaboration with prof. Michael Wagner, prosody.lab (http://prosodylab.org/), McGill University, Montreal, Canada.

Pre-event presentation at KIKA Monday 7.10.2019 @ 18:00 of SotM SEE Conference, 25-27 October, Prizren.

FLOSSK, the NGO behind Prishtina Hackerspace, is organizing State of the Map Southeastern Europe “sotmsee.org” on 25 – 27 October in Prizren.

SotMSEE is a three-day conference which brings together stakeholders in the OpenStreetMap and Geographic Information Systems (GIS) ecosystem.

Mappers, software developers, academicians, NGOs, business leaders and users of OpenStreetMap from Southeastern Europe countries will come together to create opportunities for knowledge exchange, networking and partnerships.

Please come this Monday and lets have some chat and drinks together.

OTRv4: A case around secure messaging – Sofía Celi

Sofía Celi (Centro de Autonomía Digital)

OTRv4 is the newest version of the Off-The-Record protocol. As a Privacy Enhancing Technology, it is a protocol where the newest academic research intertwines with real-world implementations. This new version asks us to revisit definitions around deniability (participation, message, online and offline), forward and post-compromise secrecy, and how important they are to the world. In this talk, we will examine the key security properties that secure messaging protocols and applications should have. We will explore how these properties are achieved in OTRv4, in particular, and why they are needed in today’s world.
