Is the proliferation of packaging formats in Python as nutzo as this author believes? https://drewdevault.com/2021/11/16/Python-stop-screwing-distros-over.html Asking because I've never been in the business of releasing "retail" Python applications or packages. Skip -- https://mail.python.org/m

Re: Sad news: Fredrik Lundh ("Effbot") has passed away

Like many others, I'm saddened to hear of Fredrik Lundh's passing. I vaguely recall meeting him just once, probably at a Python workshop, before they grew big enough to be called conferences. Effbot.org was my Tkinter, ElemenTree, and PIL reference and cheat sheet. My attention to Python developme

email.message_from_file & quoted printable

I have a bunch of old email archives I'm messing around with, for example, rendering them on-demand in HTML. Some of the files use quoted printable content transfer encoding. Here's one (with a number of headers elided): >From classicrendezvous-admin Mon Dec 4 15:29:22 2000 Message-ID: <027801bf

Gunicorn - HTTP and HTTPS in the same instance?

Hopefully some Pythonistas are also Gunicornistas. I've had little success finding help with a small dilemma in the docs or in other more specific sources. I'm testing out a new, small website. It is just Gunicorn+Flask. I'd like to both listen for HTTP and HTTPS connections. Accordingly, in my co

Re: Gunicorn - HTTP and HTTPS in the same instance?

Thanks all. I was hoping to get away without something more sophisticated like NGINX. This is just a piddly little archive of an old mailing list running on a single-core Ubuntu VM somewhere on the East Coast. Speed is not a real requirement. Load balancing seemed like overkill to me. Still, I gues
