Most of your time is going to involve processing/cleaning/munging data. How do you know your data is clean? Sometimes you know what you need beforehand, but other times you don't. We'll cover the basics of looking at your data and getting started with the Pandas Python library, and then focus on how to "tidy" and reshape data. We'll finish with applying customized processing functions on our data. EVENT: PyData DC 2018 SPEAKER: Daniel Chen PERMISSIONS: PyData provided Coding Tech permissions to republish PyData talks.

HTTP has been gradually adding lots of new and exotic headers, and more are on the way. Learn about current best practices with Vary, Link, Content-Security-Policy, Referrer-Policy, Client-Hints, Clear-Site-Data and Alt-Svc, upcoming features such as Feature-Policy and proposals like Variants, Early-Hints and Origin-Policy. HTTP gives you incredibly powerful control over many aspects of the way a browser will process the page and is often a more effective or more secure option than trying to achieve the same effect with tags or script in the page.

Ahh… CSS and performance. Two of Harry’s favourite things! But how well do they play together? It depends… In this very matter-of-fact talk, he’ll be looking at all of the different ways CSS can make our websites faster or slower. From the common and perhaps more obvious, to the unusual and obscure ways in which CSS can impact performance for better or worse.
