#Visualization shows ownership of Cars, Bicyle, Two wheelers and also the households that dont own any of these

Why is this critical to know?

Before going into the thread, let us clarify about the data. The data is an end product of a survey which surveyed around ~6,40,000 households across India

Data represented in this viz are aggregated at state level so rural-urban or other geo nuances might be hidden

Also they indicate ownership of vehicles and it would not truly reflect the transport mode share which in particularly urban areas, everyday commute in personal vehicles could be lesser as some people would take public transportation

A thought-provoking question for everyone in the crypto community.

Why is $XRP & $XLM listed as stable coins by @WorldBank?

My idea is settlement fees and transfer times are stable (4 seconds + less than 1c fee) and for funds moving there is minimal fluctuation in 4 seconds
Compare 4 seconds to the broken correspondent banking system fees & exchange rates, which also take 5-7 days to settle. (That is not stable)

Example:
1. Send 1 million $
2. Bank has ledger with XRP / XLM
3. Sends tokens to other bank - 4 seconds
4. Receiving bank Converts 2 Cash
This ecosystem infographic of $XLM was created by the utility artist / deep researcher @XX_1133_1221_11

New preprint @PsyArXiv from @LinChujun & me! "Fooled by beautiful #data: #Visualization aesthetics bias trust in science, news, and social media." Across 4 studies, we show that people (mis)place more trust in more beautiful graphs. Paper: psyarxiv.com/dnr9s/ Explainer 🧵👇
As data have become more plentiful and important to our daily lives, data visualizations have become common across many spheres, including the news media (e.g., @FiveThirtyEight), social media (e.g., @DataIsBeautiful), and scientific research in academia and industry.
People use data visualizations - such as Covid tracking graphs, weather forecast maps, stock price charts - to interpret the world, and make important decisions. Ideally, these graphs can improve those decisions, but misleading graphs can also bias and confuse us.

@Psy_of_Money by @morganhousel is full of condensed wisdom in every chapter. I have read it over and over and sent few copies to my friends.
It's my first attempt to create a chapter-wise visualization to help everyone.

🧵1/ The #CDC update today (2/26) on "Ventilation in Schools and Child Care Programs" looks like good progress.

Details on #ventilation, #filtration, #bettermasks, w/ helpful links. Seems they're listening to @kprather88 @j_g_allen @CorsIAQ and others?
cdc.gov/coronavirus/20…
2/ The relatively short #CDC page seems to have more succinct, yet clear #K12 guidance & connection to other pages of support.

Though I admit, I haven't digested yet fully. What are your takes? (also e.g. @jljcolorado @linseymarr @ProfCharlesHaas @Don_Milton @ShellyMBoulder)
3/ I was pleased to see early mention that "Wearing a well-fitting, multi-layer mask helps prevent virus particles from entering the air or being breathed in by the person wearing the mask."

(BTW, need for good fit implies aerosols)

How seriously is past volatility a fair estimate of future volatility or risk useful in financial models?
@GARP_Risk
Historical Volatility based on empirical data sample observations.
Data Sample Observations can be historic baseline data for a particular asset class/exposure or simulated data derived from iterations using some historical data sets.
Another branch of data which can be used to observe future volatility is exploratory data drawn from within a sample or a population using data #visualization tools.

This technique is becoming popular as data science and machine learning advancements are taking place

1/5 #TropiCon20 Identifying individuals is crucial for #conservation. If individual identity is known #supervised #classification can be used. What if we don’t know who is calling? We tested if #unsupervised methods can distinguish between #gibbon females (listen below).
2/5 #TropiCon20 Gibbons are #apes found in Southeast #Asia. The recording above is from one #gibbon female, and the recording below is from a different #gibbon female. Can you hear (or see) the difference? We classified > 30 females with > 95% accuracy using #supervised methods.
3/5 #TropiCon20 #Supervised methods need labelled training #data; #unsupervised techniques don't. We used an existing dataset of #gibbon female calls to test how well three #unsupervised algorithms could distinguish between #gibbons. #Affinity propagation #clustering did best!

If you are using matplotlib in your day to day coding activity and didn't no the crux of it, I want to you take a look at this below thread. I'm sure you will learn and apply it.

So, here is what all we need to know about matplotlib, an excellent visualization library in python
1. In this thread we will go through some basic patterns and practises to help you get started with the library

It will basically help us plot the data into the figures and can contain axes, i.e. an area where points can be specified in x/y/z co-ordinates

First let's import it Importing the library
2. The simple way of creating axes is using pyplot.subplots and we can Axes.plot to draw some data on the axes.

Below is how we can do it. using pyplot.subplotsOutput of the subplots

Thread: #MobProgramming seems to create a really positive impact on #collaboration. Here are some resources that helped me exploring Mob Programming. I also share my own agenda for introducing it to teams. Thank you lovely filter bubble for teaching me. You are awesome!
Two very valuable #Podcast episodes for understanding the concepts of #MobProgramming with two of its masterminds. Great interviews by @timothep in his Podcast @DevJourneyFM:
Interview @WoodyZuill: bit.ly/2RVODf6
Interview @LlewellynFalco: bit.ly/2sAW40v
The Mob Programming Guidebook by @maaretp: bit.ly/2srEPih

Read this and you can start with your first session using #MobProgramming.
This document was, what got me hooked. Thanks to @timothep for showing me.

visualizing "the work" at the program/portfolio level is one the single most powerful things a team can do to collectively improve how they work

the fascinating thing is the resistance (1/9)
#kanban #agile #programmanagement #visualization

Board Credit: @keithadam @Optimizely
2/9 Power and ambiguity. For some...power is maintained through opacity and ambiguity. Making work visible and/or making ambiguity visible is a direct threat to that way of trying to control a situation.
3/9 With visibility, there is the constant threat of micro-management. Flying under the radar is sometimes the only way to "get stuff done without people meddling. If everyone saw our roadmap, they'd keep poking holes in it!"

Now up: Zachary Brown, Lead Data Scientist at S&P Global on #DataScience and #OpenEducation for the enterprise. Dayjob: #AI, Sidehustle: building #digital skills using #opensource #ODSCWest @School_GC
#DigitalLiteracy - Why? Effective work today requires a lot of associated learning. @linuxfoundation @github #VersionControl #Visualization -- continuous learning is critical. Optimal tools & processes are probably not the ones you are using now (Matlab vs. Scikit-Learn)
Need an evolving understanding for what tools are available today to get your work done. If you want your business people to work with your #datascience team, they need to understand what data is and what it can do. Also helps to avoid chasing buzzwords and bling.
