How do you test code designed to run on a large and expensive computing cluster? How do you reproduce complex, time-dependent emergent behaviour of a cluster of network components? A discrete event simulation is like the event loop you find in asynchronous applications, but simplified. Instead of waiting on all sorts of file descriptors, there …

I don’t often share config snippets since they are so specific to the way I have things set up. You will most likely have to adapt this to your …
Growing plants and then burying them or incorporating them into soil is one of the few practical and efficient things we can do to remove CO2 from the atmosphere and permanently store it. Agricultural wastes such as rice husks, when incorporated into soil at the site of production, readily mineralize, becoming encased in silica, preventing …
