fast-csg is still a work in progress.
For large models it works best with CGAL/cgal#5461 in CGAL and used in OpenSCAD by openscad/openscad#4107.
If you want a sneak peek of the new world, enable fast-csg-remesh in the following build:
( git clone https://github.com/sloriot/cgal \
-b PMP-decimation --depth=1 \
cgal-sloriot-PMP-decimation && \Only happens in mingw32 64bit builds (whether building in Windows on a msys2 env, or cross-building from linux w/ the MXE environment).
docker run -it openscad/mxe-x86_64-gui:latest
apt install -y vim cmake
# Then paste the script above
| #!/bin/bash | |
| # | |
| # Beautifies output of `wg show` using config names from pivpn | |

| wg show | awk "BEGIN { $( | |
| # Map peer to preshared key | |
| wg show all preshared-keys | awk '{ print "key[\"" $2 "\"] = \"" $3 "\";" }' | |
| for f in $( ( . /etc/pivpn/wireguard/setupVars.conf ; echo $install_home ) )/configs/* ; do | |
| # Map preshared key to config name |
This script runs certbot in manual mode with a custom adhoc local DNS server (written in node.js using my fork of joyent/node-mname) to respond to its challenge.
The Let's Encrypt non-profit does an amazing job at helping hosting providers provide SSL certificates for free to their customers. This should be your first choice to get one, but maybe your provider prefers charging you for said certificates. That's where we come to play.
If you've just bought a domain and have a Unix machine connected to the internet (laptop, VPS or dedicated instance), you'll get your SSL certificate in 10 minutes chrono. Let's start!
