Undervolting linux ubuntu 18.04 (XPS 9570 i9 32GB RAM)
View gist:9f9db7bc95396a48b240f5c3a42cf944
Very useful for the i9 XPS 9570 overheating on Linux. Since I use Linux for development, I don't use the nvidia that comes
with the note and also don't need turboboost enabled, even running dozens of docker containers. I was having problems with
temperature. Notebook was getting so hot it was hard to type for more than 4 hours straight.
Here are my temperatures before undevolting:

1 - Install Virtual Box, get an ISO copy of windows installation and open Bootcamp on Mac (Action > Download drivers) to get
the drivers for windows
2 - Create a "ramdisk" that will actually point to your external ssd. For this you need to know the disk (you
can simply type mount on terminal and figure out the disk number by yourself). After you know the number, type this in

Running Rancher locally (with two hosts) using MacOS Docker and VirtualBox


Rancher is an open source project that provides a complete platform for operating Docker in production. It provides infrastructure services such as multi-host networking, global and local load balancing, and volume snapshots.

This documentation describes how to run Rancher localy for development and evaluation propuses.

I'm using Docker for OSX (native) but even for this to work you will need to install VirtualBox.

View gist:80890cccf1ba3bdcb76449d3e44c11fa
Pick an element in the HTML panel of the developer tools and type this in the console:
In WebKit and Firefox, $0 is a reference to the selected DOM node in the elements tab, so by doing this you get the selected DOM node scope printed out in the console.
You can also target the scope by element ID, like so:
