Subject: [Pandas-dev] Crypto project to fund open source
Message-ID: <CAEk5N5vYU6EF79xLW3R0rv6cYmk6WzeV0deMV72BTHDDXBbg+Q@mail.gmail.com>

Hi,

I've been contacting regarding a crypto project that aims at funding open
source projects. Not sure about the details, but seems like if we register
pandas, we'll be getting funds as the crypto is mined (after users endorse
pandas I think).

Not so familiar myself with crypto or the project, but just in case anyone
finds it interesting and wants to add pandas to it: https://devprotocol.xyz/

Cheers,
Marc

Another follow-up: the proof-of-concept now is merged in the master branch,
and I am currently working on making it more feature complete (see

Hi all,

Google has flagged pandas docs as malicious. This is resulting in many
messages from Cloudflare and Rackspace to web at pydata.org. Anyone know what
might have caused this?

Looks like it only affects the stable documentation. The dev docs 
https://pandas.pydata.org/pandas-docs/dev/ are not flagged.

The stable docs says it was generated on Feb 9, maybe connecting to the 
server where docs are uploaded and manually checking that there are no 
file modifications after that date could help? If it's not a false 
positive. Other similar services don't seem to be flagging pandas docs, 
just Google.

Subject: [Pandas-dev] Towards deduplicating APIs and behaviors - level
 aggregations
Message-ID: <CAFDZhWC3Oks2tJgoTjC7=T1ZjTrCBqGWkHPExZLkM_NOnBb1Cg@mail.gmail.com>

Hi team,

I was hoping to open a discussion on deduplicating and ideally simplifying
the pandas API. There are multiple cases where certain operations are able
to be called many different ways. For concreteness, I propose to start with
the `level` parameter to aggregations.

In the wild, I do not see a significant number of uses of the `level`
parameter for sum/prod/count/etc. Internally, it is simply rewritten as a
groupby:
https://github.com/pandas-dev/pandas/blob/v1.2.2/pandas/core/generic.py#L10549-L10558.
My proposal is that the `level` parameter to these aggregations be
deprecated in favor of `groupby` with the `level` parameter. To me at
least, the `groupby` syntax is more clear about what to expect in terms of
output.

I am happy to help contribute the changes necessary. I can also open an
issue if GitHub is a better place for this discussion.

Devin

My proposal is that the `level` parameter to these aggregations be deprecated in favor of `groupby` with the `level` parameter. To me at least, the `groupby` syntax is more clear about what to expect in terms of output.
