When running FastAPI app, all the logs in console are from Uvicorn and they do not have timestamp and other useful information. As Uvicorn applies python logging module, we can override Uvicorn logging formatter by applying a new logging configuration.
Meanwhile, it's able to unify the your endpoints logging with the Uvicorn logging by configuring all of them in the config file log_conf.yaml.
Before overriding:
uvicorn main:app --reload

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.
ssh, ssh-add and ssh-keygen on most computers| # Put in your ~/.ssh/config | |
| ### Problem | |
| # | |
| # You are on a public WiFi network that blocks SSH ports but you don't want to switch | |
| # to pushing your Github changes to GH remotes via HTTPS nor do you want to change the | |

Just documenting docs, articles, and discussion related to gRPC and load balancing.
https://github.com/grpc/grpc/blob/master/doc/load-balancing.md
Seems gRPC prefers thin client-side load balancing where a client gets a list of connected clients and a load balancing policy from a "load balancer" and then performs client-side load balancing based on the information. However, this could be useful for traditional load banaling approaches in clound deployments.

gRPC "works" in AWS. That is, you can run gRPC services on EC2 nodes and have them connect to other nodes, and everything is fine. If you are using AWS for easy access to hardware then all is fine. What doesn't work is ELB (aka CLB), and ALBs. Neither of these support HTTP/2 (h2c) in a way that gRPC needs.
Mobile Safari does not support position: fixed when an input focused and virtual keyboard displayed.
To force it work the same way as Mobile Chrome, you have to use position: absolute, height: 100% for the whole page or a container for your pseudo-fixed elements, intercept scroll, touchend, focus, and blur events.
The trick is to put the tapped input control to the bottom of screen before it activates focus. In that case iOS Safari always scrolls viewport predictably and window.innerHeight becomes exactly visible height.
Open https://avesus.github.io/docs/ios-keep-fixed-on-input-focus.html in Mobile Safari to see how it works.
Please avoid forms where you have several focusable elements because more tricks to fix position will be necessary, those were added just for demonstration purposes.
