Worked on using the new deployment context feature of fastdeploy to automate deploying cast_hosting instances for my podcast hosting SaaS. It finally worked and the hardest part of this was getting the traefik config right. If users can choose domain names by themselves, you have to use wildcard certificates. This means that you have to use an API key for your DNS provider allowing traefik to manipulate DNS records for the dnsChallenge, which is the only one supporting wildcard DNS. But then you still have to get both this part and your httpChallenge based certificates to work well together. Ok, here's the static config part that made traefik work for me.

Additionally, I did two programming streams last week, which is an improvement. And then there was an interesting discussion on the PyDDF telegram channel about automatic speech recognition. I haven't looked at this topic since mid-2019 and wow, a lot is going on there. Maybe it's even possible to train an asr model for german just by using existing labeled training data like the Mozilla common voice dataset plus lots of unlabeled audio data (podcasts maybe?).

• Not sure if this is a controversial opinion or not: unit tests should make up a minority segment of your overall automated test suite (Twitter Thread by Simon Willison) | I heard someone calling the type of tests Simon describing here as perimeter tests - and a few years ago, I would have completely agreed. Now I'm not so sure anymore. If the core of your application is doing crud stuff and mostly reading and writing from a database, then well: yes (probably most web applications today fall in this category). But if you have complex business logic and the crud/database part is not that important, then unit tests are maybe the way to go. Lately I also discovered the joys of mocking out your database with an in memory repository and have my test suite run in under 1s, that's just fun to work with. While even having to wait for a few minutes inevitably slows you down.
