In principle, this is pretty much exactly what the asvs are supposed to represent. ---- You have demonstrated that you are willing to repeat yourself more than I am, to the point that I find pandas interactions more frustrating than fulfilling. I'm going to step away for a little while.

Hi Reshama, I think that's a great idea, though perhaps 30-45 mins is a bit long for a hands-off talk on how to contribute. How about: - 5-10 minute talk in which we show the contributing process, and then - for the rest of the session we stick around to answer questions / debug any errors that come up while attendees try to set up their development environment I'd be happy to do this if it's something you'd like.

period index bug in pandas 1.1.0
by McIntosh, Jonathan Sept. 17, 2020

Sept. 17, 2020

Hello, I encountered a bug in pandas 1.1.0 after updating from 1.0.5 that I wanted to pass along. If a period range is created that extends past the maximum timestamp date of 2262-04-11, then the period range is shifted back by an hour after this date. The screenshots below show an example with the shifted times highlighted in yellow. [cid:image002.png@01D68C2D.F014CBC0] [cid:image004.png@01D68C2E.1DC2AC90] Thanks, Jonathan Jonathan McIntosh Water Resources Engineer 970.498.1831 | jmcintosh(a)rti.org 2950 East Harmony Road, Suite 390 | Fort Collins, CO 80528 [cid:image001.jpg@01D68C21.1CA54190]

Remote dev sprint - September 4-5
by Joris Van den Bossche Sept. 2, 2020

Sept. 2, 2020

Hi list, A late notice, but later this week (Friday-Saturday September 4-5) we are holding a remote dev sprint. The sprint is not meant to onboard newcomers to contributing (there will certainly be future sprint targeting that!), but if you are a regular contributor to pandas (or a related package), and want to join virtually, that's certainly welcome! More details (zoom / chat links, agenda, will be filled in later as well) can be found in this doc: https://docs.google.com/document/d/1eS3H0RrBUmUPQEWgSFOB7r7e-D431yD6u_NnVVx… Joris
