Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

Run the following command and copy the ID of your VM

VBoxManage list vms
=> "virtualMachine" {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}

Go to the Vagrant project configuration folder

Note: these instructions are for pre-Sierra MacOS. Sierra (10.12) and newer users see https://gist.github.com/gravitylow/fb595186ce6068537a6e9da6d8b5b96d by @gravitylow

In this article, I will share some of my experience on installing NVIDIA driver and CUDA on Linux OS. Here I mainly use Ubuntu as example. Comments for CentOS/Fedora are also provided as much as I can.

	new_tab = function (narr, nrec) return {} end

	local _M = new_tab(0, 155)

	# This assumes you have access to the system via SSH already, and need
	# remote VNC access as the same user, and you want only the primary display.
	export DISPLAY=:0

	export VNC_PASSWORD="dm5jX3Bhc3M=" # vnc_password (a character limit is enforced?)
	# Sadly many common VNC clients don't support encryption.

	# The trick is to link the DeviceSupport folder from the beta to the stable version.
	# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)

	# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
	sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

	# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

	# (A similar approach works for older versions too, just change the version number after DeviceSupport)
