Showing User’s application in Show all applications

On ubuntu, when you press Super key twice or press Super+A, you see applications installed on host. But, not all applications are installed via dpkg or snap. for example, Postman and Bitwarden doesn’t provide installers instead they provides something like App Image.

I place such programs in ~/Applications. and I want to run this kind of program conviniently using Super key like Spotlight search in Mac.

Register mDNS records to AWS Route53

In local network, I can use mDNS names like DESKTOP-RHM4944.local, but I cannot use mDNS name over OpenVPN. I uses openvpn to access office network, and I want to be able to find out client IP of certain PC. and the PC uses DHCP to obtain dynamic IP.

I have AWS environment, so I can use Route32 to resolve local hostname.

The network

• AWS VPC
• EC2 with OpenVPN Server
• RaspberryPi on Office network (connected to OpenVPN Server)
• Client Laptop (as Remote Worker)

AWS Route53 Private Zone

• Create Route53 Private Zone to be used as .local alternative. I will connect DESKTOP-RHM4944.office instead of DESKTOP-RHM4944.local
