Multi Link Example for http://www.robschmuecker.com/d3-js-drag-and-drop-zoomable-tree/#comment-6190

Added an additional link between nodes at the bottom of the dndTree.js file.

This example pulls together various examples of work with trees in D3.js.

The panning functionality can certainly be improved in my opinion and I would be thrilled to see better solutions contributed.

One can do all manner of housekeeping or server related calls on the drop event to manage a remote tree dataset for example.

One-line certificate generation/renews with Letsencrypt and nginx

Prerequisites : the letsencrypt CLI tool

This method allows your to generate and renew your Lets Encrypt certificates with 1 command. This is easily automatable to renew each 60 days, as advised.

You need nginx to answer on port 80 on all the domains you want a certificate for. Then you need to serve the challenge used by letsencrypt on /.well-known/acme-challenge. Then we invoke the letsencrypt command, telling the tool to write the challenge files in the directory we used as a root in the nginx configuration.

I redirect all HTTP requests on HTTPS, so my nginx config looks like :

server {
