On: Jurigged – Hot code reloading for Python

[musingsole]

In a proper managed environment (whatever that may mean...), this could be useful as a means for continuous integration. Maybe not worth all the hassle, but maybe there's a usecase where this would be a beloved silver bullet.

Hot code reloading (ala Erlang) is often used in embedded devices for control code where restarting is very expensive. Mostly telco and networking devices.

[dnautics → ohples]

we use it in prod to instrument code to check up on some internal data, say, from the database, when some forensic analysis is needed

[kikos → musingsole]

We use something similar in some of the web crawlers in my company, we dynamically load the module that selects the data from a web page so that if something (website and/or requirement) changes we can just swap the module without downtime.
