Predicting future using past data and SQL - Tadas T
People from persicope.io take you through a solution to a problem they had: predicting weekly server load growth, step by step, with clear explanations. I highly recommend subscribing to their blog updates as the articles are consistently good.
Where are your requests coming from? - Tom S
A handy gem that can be used to check whether a request has been made by a bot (e.g. in your controller:
request.bot?). Great for filtering out real users for analytics or avoiding unwanted API calls when a bot visits the site.
Is testing a design tool? - Pedro M
