4:11p	Varrazzo: Thinking psycopg3 Psycopg is the database adapter used by most Python programs needing to work with the PostgreSQL database manager. In this blog post, psycopg maintainer Daniele Varrazzo looks forward to the next major version. "There is a chance now to rethink how thick the C libpq wrapper should be. We can reduce the C implementation to a minimal wrapper around the libpq (replaceable by a CFFI Python wrapper if compiling C is not available on the client), using it as a foundation to build a familiar DBAPI blocking interface. A blocking behaviour is not bad in itself: it allows to write most of the programs, the ones which don't need crazy concurrency, in a simple and familiar paradigm; the async layer would be available under the hood to squeeze the best performance in programs who have embraced an asynchronous pattern and framework."

8:09p	Data Sharing and Open Source Software Help Combat Covid-19 (Wired) Wired has an article on an open-source tool that is being used to track strains of Covid-19 throughout the world. "In the case of the Seattle area teenager, genetic data about his strain of Covid-19 was uploaded to Gisaid, a platform for sharing genomic data. Then researchers at Nextstrain made the connection with the earlier patient. Nextstrain is an open source application that tracks the evolution of viruses and bacteria, including Covid-19, Ebola, and lesser-known outbreaks such as Enterovirus D68 using data sourced largely from Gisaid. Hodcroft and other researchers involved with the project analyze the data shared on Gisaid for mutations and visualize the results. That’s how the team was able to spot the connection between the two Covid-19 cases in Washington." (Comment on this)
9:35p	[$] A QUIC look at HTTP/3 The Hypertext Transfer Protocol (HTTP) is a core component of the world-wide web. Over its evolution it has added features, including encryption, but time has revealed its limitations and those of the whole protocol stack. At FOSDEM 2020, Daniel Stenberg delivered a talk about a new version of the protocol called HTTP/3. It is under development and includes some big changes under the hood. There is no more TCP, for example; a new transport protocol called QUIC is expected to improve performance and allow new features. (Comment on this)
