In the previous blog entry [Pi-hole with DNS-over-TLS] I set up stubby for dns-over-tls on the pi-hole. I want to do the same now for DNS-over-HTTPS (DoH), but neither Stubby nor Unbound support the young protocol which answers DNS queries via HTTPS. Some browsers have now integrated DoH, but I would like to protect all DNS queries from my home network. Therefore I use the client of cloudflare written in Go:

Django (/ˈdʒæŋɡoʊ/ jang-goh) is a free, open source web application framework written in Python. Here you can find a tutorial from Django, if you don't know it yet and want to try it out: https://docs.djangoproject.com/en/2.1/intro/tutorial01/. The next article is aimed at experienced Django developers.
Django and Microservices
I have been using Django together with the task engine Celery for some time for asynchronous and distributed processing over several systems. Recently I am working on the topic "Microservices" and how they can be realized together with Django. (more about Micro...
The new ACME v2 protocol for Let's Encrypt certificates is live! Among other things, this now allows wildcard certificates to be obtained. This allows many individual certificates (such as subdomains) to be reduced to one, and no additional certificates are required for multiple subdomains.
Some time ago I installed a Pi-hole on a Raspberry Pi at home to filter unwanted ads. This works very well after some startup problems (self-made firewall problems). This will now filter all network traffic on my network, including TVs, smartphones, tablets, and so on.
Especially devices such as smartphones, which often feature in-app ads, benefit from filtering DNS requests directly on the DNS server. Not only ads are filtered, but also tracker from Samsung TV, Google Analytics or Sonos (which can't be turned off).
