Subject: [CentralOH] DoJo meeting again Thursday (Oct 8) -- using Gather Town
Message-ID: <F01E99E5-341A-447F-ADC1-4A52DDBE8F0F@fastmail.com>

Hi everyone,

The DoJo meets every Thursday online starting at 6:00 pm. You are 
welcome whether you are brand new to Python or have many years of 
experience!

DoJos are informal Python meetings. Join us at any time during the 
meeting and bring your Python questions and problems. DoJos are like 
group study sessions. Digressions from Python are common. All are 
welcome to the DoJos. On occasion we have presentations about Python 
topics.


For the duration of the social distancing, we will meet online.  We are 
going to use __Gather Town__ again.  The link is:

	https://gather.town/NRsxe91HZKpkM7hk/COhPy

The advantage of GatherTown is that you can break off and have separate 
conversations with other people. Just go to a table. (You may have to 
move up or other directions to find an empty table.) When other people 
come to the same table, all the people at the same table can hear each 
other without disturbing the main discussion. Join us and give it a try!

Cheers!
Travis

Hi Folks,

As noted here, big changes are coming to __pip__ this month involving 
the dependency resolver.

-	Pip 20.2 (already out) has new resolver in it.  Add

		--use-feature=2020-resolver

	to use.

-	Pip 20.3 (Probably will be released in January 2021) will use the new 
resolver by default, but a flag is available to use the current 
resolver.

-	Pip 21.0 (Probably will be released in April 2021) will use the new 
resolver only.  The current resolver will no longer be available.

Details and links to more info and a short video are given below.

Changes are coming to pip, Python's package installation tool, in 
October 2020. Please read and share this migration guide: 
https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-2-2020 
.

We're working on improving the Python packaging toolchain, foundational 
work that will (in the long run) make the whole Python package 
installation experience way less confusing.

The pip team made a 2-minute video to explain what's up:

We are also doing user experience studies, and want you to sign up if 
you ever do anything with Python (whatever your level of 
skill/experience): 
http://www.ei8fdb.org/thoughts/2020/03/pip-ux-study-recruitment/

https://mastodon.social/@brainwane/104950044427849411 is a good toot to 
boost, and https://twitter.com/ThePSF/status/1311038036013199363 is a 
good tweet to retweet, if you want to help us get the word out.

MORE DETAILS: at the migration guide at

Great talk by Jim on pathlib. I folded it into a. project for my Panda3d class. Very smooth. I will talk about it at this week's Dojo.
