How to Decide: When to Use What In Office 365 - SharePoint Fest DCRichard Harbridge
Your users may struggle with these questions:
Should I share a message via Skype for Business instead of Yammer, Office 365 Groups, or Exchange?
Should I collaborate on data using an Excel sheet or a SharePoint list?
Should I share a file in Outlook, in a meeting, from OneDrive for Business, on Yammer, in a Group, or in a SharePoint site?
What happens when your users can't decide what technology or feature to use? They use what they know, or what’s easy; even if better options exist.
In this session, join Richard Harbridge as he helps you maximize the value of your Office 365 investment by providing the guidance you need to help your users make better, more effective decisions on how they get work done.

Python and PostgreSQL: Let's Work Together! | PyConFr 2018 | Dimitri FontaineCitus Data
Python is often used to maintain application backends. When the backend should implement user oriented workflows, it may rely on a RDBMS component to take care of the system's integrity.
PostgreSQL is the world's most advanced open source relational database, and is very good at taking care of your system's integrity. PostgreSQL also comes with a ton of data processing power, and in many cases a simple enough SQL statement may replace hundreds of lines of code written in Python.
In this talk, we learn advanced SQL techniques and how to reason about which part of the backend code should be done in the database, and which parf of the backend code is so easier to write as a SQL query.

3 The wind chill factor represents the equivalent air temperature at a standard wind speed that would
produce the same heat loss as the given temperature and wind speed. One formula for computing
the equivalent temperature is

if 1.79 ≤ v < 20
if v ≥ 20
where v represents the wind speed (in meters per second) and t represents the air temperature .
Compute the wind chill for an air temperature of 15°C and a wind speed of 12 meters per second.
