Doing winget install fails with a message "Failed when searching source: msstore An unexpected error occurred while executing the command: 0x8a15005e : The server certificate did not match any of the expected values."

I tried to install Windows Terminal using the command below -

C:\>winget install Microsoft.WindowsTerminal

But got the following error message instead.

Failed when searching source: msstore An unexpected error occurred while executing the command: 0x8a15005e : The server certificate did not match any of the expected values.

The following packages were found among the working sources.
Please specify one of them using the --source option to proceed.

Batch convert file line ending from Windows to Linux using Notepad++

Working on cross-platform project means you have to be careful with file line endings. If for some reason the files were not using the correct line endings Notepad++ can be used to do batch conversion of the files. To do so, open Find in Files (Ctrl+Shift+F) and use the following options:
Find what: (\r\n)
Replace with : \n
Filters : *.*
Directory : C:\Temp
Search Mode: (o) Regular expression

ESXi 6.5.0 fails to start a VM with a message "Maximum virtual machines limit reached: ## (#### worlds)"

Maximum virtual machines limit reached: ## (##### worlds)

ESXi 6.5.0 by default determines the maximum number of VMs dynamically at runtime. In certain scenarios this might be too conservative and you will not be able to start a virtual machine. If you are observing a message like below when starting a VM then you have hit the limit.

Maximum virtual machines limit reached: ## (##### worlds).

This behavior is controlled by VMkernel.Boot.maxVMs in Advanced settings. Change this to a value that might be reasonable based on CPU, memory and network capacity. The same setting can be changed from SSH shell like below:

[root@localhost:~] esxcli system settings kernel set -s maxVMs -v 1024

Reboot the server for this change to take effect.
