.NET Workload Troubleshooting

To install the maui workload, you have two options:

dotnet workload install commands
Visual Studio on Windows can install .msi files for each workload pack. Note that the concept of a "Visual Studio workload" is different than a ".NET workload".

VS for Mac's installer and updater use dotnet workload install commands. It's considerably simpler to get a Mac machine to a clean state.

What do Etcd, Consul, and Zookeeper do?

Service Registration:
- Host, port number, and sometimes authentication credentials, protocols, versions numbers, and/or environment details.
Service Discovery:
- Ability for client application to query the central registry to learn of service location.
Consistent and durable general-purpose K/V store across distributed system.
- Some solutions support this better than others.
- Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
Centralized locking can be based on this K/V store.

Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

Using a Local Registry with Minikube

Install a local Registry

These instructions include running a local registry accessible from Kubernetes as well as from the host development machine at registry.dev.svc.cluster.local:5000.

Use the docker CLI to run the registry:2 container from Docker, listening on port 5000, and persisting images in the ~/.registry/storage directory.

	# Apple Silicon laptops with firmware > 13.0 have a native charge threshold that does not required any userspace daemon running.
	# This native limit works even when the laptop is sleeping or powered off therefore it is preferable to the userspace daemon.
	# Nonetheless, it only works with fixed thresholds (80% as upper limit and 70% as lower limit).
	# CHWA key is the one used to enable/disable the native limit. 01 = 80% limit, 00 = no limit
	##
	typeset -g smc_command="/usr/local/bin/smc"
	typeset -g smc_charge_limit_key="CHWA"
	typeset -g smc_charge_limit_status_on="01"
