A talk about concurrency by Renghen
One of the sessions that I was able to shoot the whole of it during the Developers Conference 2019, is that of Renghen Pajanalingum aka Thanos. He spoke about the different techniques to attain concurrency when writing software.
Due to display issues (which I snipped from the video) the presentation started some minutes later than scheduled. Renghen had to rush the end part and unfortunately he even had to skip the code demo. If you'd like discuss the concurrency techniques with him though, you can reach out to him on Twitter.
