Multi-factor authentication is a must have feature in any modern web application. Specially providing support for both TOTP (think applications on phone) and FIDO2 (say Yubikeys) usage. I created a small Django demo mfaforgood which shows how to enable both. I am using django-mfa3 for all the hard work, but specially from a PR branch from my friend Giuseppe De Marco. I also fetched the cbor-js package in the repository so that hardware tokens for FIDO2 to work. I hope this example will help you add the MFA support to your Django application.

Python is as popular as it is today because we have gone above and beyond to make this a welcoming community. Being a friendly and supportive community is part of how we are perceived by the wider world and is integral to the wide popularity of Python. We won a “Wonderfully Welcoming Award” last year at GitHub Universe. Over and over again, the tech press refers to Python as a supportive community. We aren’t the fastest, the newest or the best-funded programming language, but we are the most welcoming and supportive. Our philosophy is a big part of why Python is a fantastic choice for not only ..read more

In this quiz, you’ll test your understanding of Python’s logging module. Logging is a very useful tool in a programmer’s toolbox. It can help you develop a better understanding of the flow of a program and discover scenarios that you might not have thought of while developing. Logs provide developers with an extra set of eyes that are constantly looking at the flow an application is going through. They can store information, like which user or IP accessed the application. If an error occurs, then they can provide more insights than a stack trace by telling you what the state of the program was ..read more

This is a cross-post from Max Bernstein from his excellent blog where he writes about programming languages, compilers, optimizations, virtual machines. He's looking for a (dynamic language runtime or compiler related) job too. CF Bolz-Tereick wrote some excellent posts in which they introduce a small IR and optimizer and extend it with allocation removal. We also did a live stream together in which we did some more heap optimizations. In this blog post, I'm going to write a small abtract interpreter for the Toy IR and then show how we can use it to do some simple optimizations. It assumes tha ..read more

ObjectListView is a third-party wxPython widget that wraps the wx.ListCtrl. I have used it for over 10 years in quite a few different GUI applications because it works much nicer than wx.ListCtrl does. Unfortunately, ObjectListView was never integrated into wxPython core like some other amazing third-party packages were, and so it has become broken over the past couple of years such that you can’t use it with the latest version of Python / wxPython. So, I decided to fork the project, as its defects were simple enough that I could resolve them quickly. The new version of ObjectListView is now c ..read more
