Python at Nielsen
(0:30:00 Minutes)
By: Jordan Bettis, Meygha Bhat, Vamsi Guntamukkala

<p>We will talk to you about Nielsen's Connect Platform, our global, unified, open data ecosystem powered by Microsoft Azure and how we're building platform components using Python. Specifically, we'll deep dive into object-oriented data flows. As more and more data scientists write software beyond statistical models, object thinking from the field of programming can help them write test-able, maintainable and reusable components.</p>
Demystifying Machine Learning
(0:30:00 Minutes)
By: Nikola Novakovic
Experience Level: Intermediate

<p>Machine Learning is something you'll see referenced very frequently now in everything from marketing materials to sales pitches, and job postings. With so much hype it can be hard to distinguish what people mean when they say Machine Learning. In this talk we will demystify Machine Learning by understanding its core concepts and applying that knowledge to real world examples. We'll explain basic concepts like linear algebra and loss functions, figure out when to use machine learning and build an ML model that we'll be able to use in real world apps. Here&rsquo;s an in-depth list of what we'll cover: * What Machine Learning is and where it&rsquo;s being used * How to recognize when machine learning is necessary * Math 101 * Linear Regression * Live Coding Session Salary Estimator * Q &amp; A</p>

Application Security for Python Programmers
(0:25:00 Minutes)
By: James Jeffryes
Experience Level: Intermediate

<p>Python is a growing choice for business applications processing sensitive user data and performing mission-critical tasks. That makes it vital for programmers to be aware of common security vulnerabilities that can undermine the Confidentiality, Integrity, and Accessibility of these Python applications. Fortunately, many of these risks can be managed with patterns for safe handling of user input as well as tools for dependency monitoring and static code analysis.</p>

Scaling out Airflow
(0:10:00 Minutes)
By: Katie Simmons
Experience Level: Intermediate

<p>Katie Simmons, a data engineer at ActiveCampaign, will speak about the challenges and benefits of using Airflow for ETL at a rapidly growing company. ActiveCampaign has many thousands of databases - some including tables with up to a trillion rows - several APIs and new source requests coming in every week. This lightning talk will be an overview of using Airflow to extract, load and transform that data into our data lake so that it can be used for Business Intelligence and Data Science.</p>
The Philosopher's Groan: How I Finally Fell In Love With SQLAlchemy
(0:25:00 Minutes)
By: Ainsley McGrath
Experience Level: Intermediate

<p>I first encountered SQLAlchemy several years ago. I didn't get it. It seemed every line I attempted to write would drop me into 50 tabs of labarynthine documentation. Why do we have the ORM *and* Core? Should I build my tables as `Table` instances or should I be extending `Base`? How is `Base` more declarative than a function that returns `Table`s?? Can I please just write SQL??? :sob: I'm still hesitant to peek too far behind the curtain, but I do think I've finally wrapped my head around the philosophical underpinnings of the library and the different problems SQLAlchemy allows us to solve. After all, who among us works with databases that aren't problems in and of themselves?</p>
Throw away your shell scripts
(0:30:00 Minutes)
By: Nick Timkovich
Experience Level: Intermediate

<p>One of the most common languages used by Python developers is some shell script (sh, bash, cmd.exe, or PowerShell), but why torture yourself with poor design decisions from the 70s when you know Python?</p>
