Here are some notes I took from the January meeting (sorry this took so 
long to write up):

Catherine shared about a tool she wrote to walk through arbitrarily deep 
data structures: https://github.com/catherinedevlin/imperial-walker . 
This can help (among other things) to examine new data sets to 
understand the shape of the data.

Another very popular tool with a related purpose is jq 
(https://stedolan.github.io/jq/). One of Imperial-Walker's features 
emits jq expressions for each value in the data structure.
A similar (golang) tool in the same space is gron: 
https://github.com/tomnomnom/gron
jid (https://github.com/simeji/jid, also golang) is an interactive 
version of jq, also suitable for data exploration. jiq 
(https://github.com/fiatjaf/jiq) is an alternative to jid that uses jq 
under the hood.

There are a few Python libraries that wrap jq (which is itself written 
in C):
- https://github.com/doloopwhile/pyjq (most recent release in September 
2019)
- https://github.com/mwilliamson/jq.py (most recent release in February 
2016)
- https://www.drmaciver.com/2013/12/pyjq-a-work-in-progress/ (blog post, 
but the repository it points to appears to have been deleted)
I don't personally have experience with these.

We also had a good discussion about different data serialization formats 
(besides JSON). Here is an incredibly large table from Wikipedia: 
https://en.wikipedia.org/wiki/Comparison_of_data-serialization_formats

Both YAML (https://yaml.org/) and TOML 
(https://github.com/toml-lang/toml) were discussed. Each has relatively 
decent support in Python (vi PyPI packages, not the standard library). 
There's an equivalent of jq for YAML (creatively named "yq": 
https://github.com/kislyuk/yq), which is a Python library that works by 
converting YAML to JSON behind the scenes and then invoking jq. While 
looking up things for this message, I found another tool named yq, which 
seems to be written in golang without depending on jq: 
https://github.com/mikefarah/yq

If there's anything I missed, or other tools people know of which might 
be similarly helpful to the group, please share!

WE HAVE A SPONSOR! Thanks to OliveAI (https://oliveai.com/) for sponsoring
pizza and drinks this month. Check them out!

This month we will be at the new Dublin Library (in Meeting Room 1).

Guy Royse will be talking about "Understanding Probabilistic Data
Structures with 112,092 UFO Sightings"

Guy likes weird stuff?UFOs, Bigfoot, peanut butter and bologna on
toast?maybe you do too? As far as the third bullet point, well, that?s how
many sightings he has.

Now, if you?re like most developers, you probably have no idea what
probabilistic data structures are. In fact, Guy did a super-scientific poll
on Twitter and found that out of 119 participants, 58% had never heard of
them and 22% had heard the term but nothing more. He wondered what
percentage of that 22% heard the term for the first time in the poll. We?re
a literal-minded lot at times.

In this talk, we?ll briefly go over some common probabilistic data
structures; dive deep into a couple (Bloom Filter, MinHash, and Top-K); and
show a running application that makes use of Top-K to analyze the most
commonly used words in all 112,092 of his UFO sightings.

When we?re done, you?ll be ready to start using some of these structures in
your own applications. And, if you use the UFO data, maybe you?ll discover
that the truth really is out there.

This group is only as good as its inputs. Please consider helping out.

Hope to see you there!

All,

I have been informed that the Columbus Public Libraries have cancelled all
classes, programs, meetings and events at all Columbus Metropolitan Library
locations through at least March 31. This includes all reservations of
meeting rooms. We will be cancelling our March meetup and will pick back up
(hopefully) at our April 27th meeting.

Stay healthy and wash your hands :-).

Cheers,
Eric

Message-ID: <69e62f03-13ee-e8a9-ccd5-2d1b65658727@fastmail.com>

Hello all !


Today I got an email from Take Control Books, about a resource they put 
together to help people hwo have to suddenly work form home due to 
coronavirus and related issues.

The book is called Take Control of Working From Home Temporarily, is 
free, and can be found here :

https://www.takecontrolbooks.com/working-from-home/?pt=TCANNOUNCE

Also, pro tip - if at all possible, get a headset with a boom 
microphone. The ones with the mic integrated into the headphones do not 
work very well, and the built in device microphone on your phone or 
laptop will interact with the built in speakers and cause nasty echo and 
crazy feedback loops. Not to mention all the background noise that gets 
picked up as well.

Due to gamer culture, there are a ton of bulky, high markup models out 
there - but all you really need os something as simple as a Amazon 
Basics headset could work :

https://www.amazon.com/AmazonBasics-USB-Headset-Mute-Option/dp/B07QH5MDV6/ref=sr_1_4?crid=FJ316U0UAU1M&dchild=1&keywords=amazon+basics+headset&qid=1584409619&sprefix=amazon+basics+head%2Caps%2C159&sr=8-4


Also, the Logitech H390 - while you will find them all over the place, I 
personally have burned through two of them - the build quality is poor, 
and the mic has failed on both of them. Stay away from those.

Hi everyone,

Thanks to the coronavirus going around, the weekly DoJo meetings at 
SmokeHouse Brewing have been suspended.  Instead, I have set up a 
Discord server for us.  To join go to:

	https://discord.gg/dh6VZF

If you do not have a Discord account, it will probably ask you to create 
one before allowing you to join.  There is no cost to a Discord account.

This COhPy DoJo ?server? already has a text channel and a voice 
channel.  The voice channel also allows one to share a screen with the 
others on the voice channel.

I will be on the server from 6:00 pm to at least 9:00 pm each Thursday.  
Hopefully we can get together this way each week until it is safe to 
meet at SmokeHouse Brewing again.

Travis

Hi everybody,

If you have not been to the DoJo conference on Discord yet, please 
download and install the app from  https://discordapp.com/download, then 
click on the this link:

	https://discord.gg/4rhxgd

After you sign up (free) you can then join the conference.

Note, you can join the text channels with your browser, but you will 
need the app to join the voice channel and see the shared screen.

Questions?  Please let me know.

Message-ID: <0f602a97-f340-7be9-7b7d-88723be88985@fastmail.com>

Hello all !


This evening Guy Royse gave us a nice presentation on using bloom 
filters in Redis - very helpful for data analysis.

https://automatetheboringstuff.com - useful for getting a running start 
on this (and in sharing with Pythonistas in general)


https://github.com/guyroyse/data-structures - this is where the talk can 
be found


https://github.com/guyroyse/understanding-probabilistic-data-structures


We learned how to analyse UFO sighting reports with the bloom filter, 
and with Python. We also learned that Mulder and Scully?s boss was 
Assistant Director Walter Skinner

Interesting tangent - Mash: fast genome and metagenome distance 
estimation using 
MinHash
https://genomebiology.biomedcentral.com/articles/10.1186/s13059-016-0997-x


We also adjourned to discuss Pink Floyd, elasticsearch, and paw paws. I 
will have a video posted soon

Hello all,

I now have a video of last night's meeting posted on my YouTube channel 
- https://youtu.be/UwYgxKOMmsU

I am looking into what it will take to get the video onto PyVideo - in 
the meantime, thank you again for joining us !
