Extract certificate and key from acme.json

Traefik V2.3 creates a file called acme.json after a successful certification-creation (cert-provider: let’s encrypt).

To extract the certificate and key from this file I have created this bash-script:

Send Geo-location from Browser

Create a button and log the current LAT/LON when the button is pressed:

<button id="send-location"> Send location</button>
document.querySelector('#send-location').addEventListener('click', () => {

    if (!navigator.geolocation) {

        return alert ('Geolocation not supported by Browser !')

    }
    
    navigator.geolocation.getCurrentPosition((position) => {

        console.log(position)

    })

console.log output

Java: Remove brackets / leading slashes from String

My Android-app have always presented the DNS-Server(s) with brackets / leading slashes like:

How can we get rid of these unnecessary characters ?

String myIp2Dns1:

String myIp2Dns1 = String.valueOf (LinkProp.getDnsServers()) ;

Log:

Log.d("myDnsInfo - Domain - ", "Domain = " + LinkProp.getDomains());
D/myDnsInfo: dns = [/10.0.2.3]

Solution:
Manipulation of String myIp2Dns1:

myIp2Dns1 = myIp2Dns1.replaceAll("[\\[\\](){}\"^/+\"]","");

This command removes brackets / slashes / backslashes from the String.

The output looks much better now:
