Futurice Tech Weeklies

Having your website’s TLS/SSL certificate expire is not a good thing. Sometimes you might not pay enough attention and could miss a renewal deadline causing a lot of trouble for yourself and your users. It’s even worse if you have a lot of websites to manage as a hobby or in a professional setting.

Jae Lo Presti had a similar challenge. In this short TechWeeklies session, Jae takes you through the different solutions she considered, and why she decided to create her own solution in the end. The talk also includes a walkthrough of Jae’s fast and easy-to-deploy solution using vanilla Python that works correctly for the requirement. 

Presenter: Jae Lo Presti works as a software developer in Helsinki and is an active open-source contributor in her spare time.

"Parse, don't validate" is an approach to modeling data such that it is impossible to construct without verifying the integrity of the data first. Thus when using such data, one can be sure that it is already in the correct shape and no further validation is necessary.

In short, this approach makes it explicit where your data gets refined. This blog by Alexis King uses examples in Haskell, mostly because the language has a short and concise syntax. To show that such an approach works in any other language too (albeit with a bit more boilerplate approach), Jan will also demonstrate it in Java.
