One thing I can recommend that makes scripting in python with external commands a lot easier is the `sh` module:

Basically you can just `from sh import [command]` and then have an installed binary command available as function

  from sh import ifconfig
  print(ifconfig("eth0"))

theomegaon LiteFS

Thanks, that was of great help!

Just for reference, the ping command is a little different

  sudo ping6 -D -G 1500,1400 fly.io

I set an MSS to 1492 which pfsense (my router) translates to an MSS clamp of 1492-60 for IPv6 and 1492-40 for IPv4. This is a German Deutsche Telekom Fiber connection. Now everything works fine, I can request fly.io (and also discovered that https://ipv6-test.com was not working before and now does with the MSS clamping)

Does MSS clamping have any disadvantages? Are there any alternatives in my case?

theomegaon LiteFS

How could I find out if this is the case? And, what can I do about it? Disabling IPv6 obviously fixes it, but that it not a solution...

theomegaon LiteFS

Does anyone else bump into the issue, that the fly.io website does not load if requested via IPv6 on Mac? I tried Safari, Chrome and curl and neither work:

  $ curl -v https://fly.io/blog/introducing-litefs/

  * Connected to fly.io (2a09:8280:1::a:791) port 443 (#0)

theomegaon Shortest URLs on the Internet

Just to check: Could it be that pihole (dnsmasq) has an issue with these dotless domains?

I'm getting a NXDOMAIN for `dig ai.`, but when directly doing with an upstream server (i.e. 8.8.8.8 or 1.1.1.1) it perfectly works.

I assume this is the result of the `Never forward non-FQDN A and AAAA queries` setting being checked in pi-hole (which is AFAIK the default).

theomegaon Free Postgres databases for small projects

I tried to deploy an application I currently have running on Digital Ocean App Platform (their Heroku competitor) also on fly.io. The app is using Python/Django and Postgres, ideal to test.

I must say the deployment experience was great, stuff just worked, brilliant.

One question in case someone tried that: How can you customize the postgres config? I want to enable pg_stat_statements, and one needs to add `shared_preload_libraries = 'pg_stat_statements'` to the config for this. One could also make this the default maybe? It is the default on most cloud providers (AWS RDS, Digital Ocean).

theomegaon Django 4.0

Great news!

Just for reference: The latest release for Django Rest Framework is not compatible with Django 4.0 yet. At least my first attempts failed due to a missing `pytz` dependency. This is fixed in the `master` of DRF on Github. Installing `pytz` explicitly again to your project fixes DRF for now.

theomegaon Keycloak: Open-source identity and access management

I was a heavy user of Keycloak until a year ago and I can only recommend your setup if you are sure that the amount of realms is not growing. Every additional realm uses huge amount of memory in Keycloak. From how I understood the architecture, a lot of components (if not all of them) are initialized per realm.

We had huge problems modeling multi-tenancy through reals in Keycloak.

Take everything I'm saying with a grain of salt. But, if you are planning to have a lot of customers and realms, do a benchmark by creating a lot of realms and checking if you can use all of them in parallel. YMMV.
