Yesterday we had an amazing Data & AI Meetup in Frankfurt! Let’s have a quick recap!

The venue: DB Systel’s Silberturm

DB Systel kindly hosted the 15th iteration of our Data & AI Meetup on the 30th floor of the Silberturm in Frankfurt, Germany.

Welcome & Intro

Darren Cooper and I had the pleasure to welcome 200 Data & AI enthusiasts! Furthermore, we were happy to announce that our Data & AI Meetup group has 1,070 members and our brand new Data & AI LinkedIn group already has 580 members.

Reinforcement Learning of Train Dispatching at Deutsche Bahn

Dr. Tobias Keller, Data Scientist at DB Systel, showed in his session how Deutsche Bahn aims at increasing the speed of the suburban railway system in Stuttgart (S-Bahn) using Artificial Intelligence. In particular, a simulation-based reinforcement learning approach provides promising first results.

TensorFlow & Co as a Service

Sascha Dittmann, Cloud Solution Architect for Advanced Analytics & AI at Microsoft, showed in his presentation, how TensorFlow and other ML frameworks can be used better in a team through appropriate Microsoft Cloud services. He presented different ways of how data science experiments can be documented and shared in a team. He also covered topics such as versioning of the ML models, as well as the operationalization of the models in production.

Visual Analytics: from messy data to insightful visualization

Daniel Weikert, Expert Consultant at SIEGER Consulting, showed in his session the ease of use of Microsoft Power BI Desktop. He briefly highlighted the AI Capabilities which Power BI provides and showed a way on how to get started with messy data, doing data cleaning and visualize results in an appealing way to your audience.

Do you want to track your own Twitter profile? Collect your Twitter stats with IFTTT and the tstats script!

[Update 3 Aug 2018]: I hit the 11k follower mark on Twitter just a few days after the first German-language Tableau book became available on Amazon  and in many local book stores!

How to Log your Twitter Follower Stats with IFTTT to a Google Spreadsheet

tstats GitHub repository
The tstats script (on GitHub) logs your Twitter Follower Stats with IFTTT to a Google Spreadsheet

How can we log the follower statistics for a Twitter account?

In order to store these stats, I’d like to use IFTTT’s new Maker channel that was introduced last month. I have created a simple Bash script (tstats.sh) to log this data to a spreadsheet in my Google Drive. I run this as a cron job every 24 hours.

Prerequisites

Ruby:

sudo apt-get install ruby-dev

Twitter CLI:

gem install t

Authorize your Twitter account:

t authorize

A Google account, as the log is saved to a spreadsheet in your Google Drive.

An IFTTT account.

Connect the Maker and Google Drive channels to your IFTTT account.

Usage

cd into the tstats directory and edit the script with your IFTTT secret key, your IFTTT trigger event name and your Twitter screen name. Make the script executable with:

chmod +x tstats.sh

Then simply run it with:

./tstats.sh

If you receive a “Congratulations” message and an entry is added to your spread sheet, you can go ahead and add it to your cron to run at a predetermined time.

To have this script run every 24 hours, add this to your crontab (you may need to change the path):

42,09 * * * * /home/user/tstats/tstats.sh >/dev/null 2>&1

[Update 26 Jul 2018] Now on GitHub: Yes, three years later this script is still hot! However, WordPress is not the perfect place to host code. As part of my preparation for my TC18 session on Social Media in New Orleans, I moved the code to a GitHub repositroy: https://github.com/aloth/tstats
