We also look into how me can make messages quicker to distribute. For this code we use the trio functionality to wait for limited time for a task to complete, by using […]

We build out the functionality to receive messages, then distribute them to all connected users. For this part we use Trio’s nurseries to start up new running tasks: https://trio.readthedocs.io/en/stable/reference-core.html#nurseries-and-spawning We use the nursery.start_soon() function to kick off new tasks […]
Series Part 1: https://jaytuckey.name/2021/07/22/trio-tutorial-simple-tcp-chat-program-part-1/ In part 2 we look at making a tool to assist with testing the TCP server we are building: We use the built-in python socket library in the testclient: https://docs.python.org/3/library/socket.html Got any questions?

I’ve made a video about making a simple TCP-based program using Python and Trio. The video is here: https://www.youtube.com/watch?v=6JM1hgjLV-A The features I plan to build are: each user has a long running tcp connection user is asked for name on connection user sends message each other connected user receives the message In part 1 we […]
I’ve made a series of videos exploring the Internet Protocol Suite, and how it is used to make a connection to a website. It’s a deep dive into the stack, explaining all the way down to the ethernet frames that a computer sends on the local link.

It will scan a network range attached to the device it is run from, and will turn what it finds into a list of reservations for the Kea dhcp server – https://kea.readthedocs.io/ You run it something like this, giving it a network range to scan. Then network should be a […]
