History Long time ago, there were huge discussions about Python 2.7 or Python 3.xx. Fortunately, these times are gone and we’ve all gotten over the hurdle to Python 3. But are you on 3.6, 3.7, 3.8 ? or even 3.11 or 3.12 ? That’s the current Version you should use for your daily Projects ?
Status of Python versions A good indicator is this Website: https://devguide.python.org/versions/
OpenBSD It’s also recommended to check what our Operating System is installing by default, or what you can get from their Package Repository.

Little Test with HTMX & Nginx recently, i saw the Keynote - “Full-Stack Python” (Andy “Pandy” Knight) and i read an article about html & websockets. So I thought why not give it a try?

How to Build your own AnyCast Network you’re using anycast every day. all public resolvers (1.1.1.1, 8.8.8.8, 9.9.9.9) for example are anycast ip’s and hence, many servers distributed around the world which listen and announce the same ip address.
we can build a proof of concept, how to build such a network, for a few $.
Requirements AS Number Anycast heavily depends on BGP. So, you need a own AS Number.
Let’s have a look a the old and simple “cgi-bin” stuff on OpenBSD. The Webserver is written by the OpenBSD Guys, and it runs in a chrooted environment.
switch to cgi-bin dir cd /var/www/cgi-bin/ ip.cgi create the file under /var/www/cgi-bin called ‘ip.cgi’
cat << 'EOG' > ip.cgi #!/bin/sh cat << EOF Content-type: text/html <html><head> <title>IP: $REMOTE_ADDR</title> </head><body> <p>Your IP address is: $REMOTE_ADDR</p> </body></html> EOF EOG Set Owner & Permission chmod 500 ip.
