How to make Powershell remember the SSH key passphrase.

You should not use the Open SSH client that comes with Git for Windows. Instead, Windows 10 has its own implementation of Open SSH that is integrated with the system. To achieve this:

  1. Start the ssh-agent from Windows Services:
  • Type Services in the Start Menu or Win+R and then type services.msc to launch the Services window;
  • Find the OpenSSH Authentication Agent in the list and double click on it;
  • In the OpenSSH Authentication Agent Properties window that appears, choose Automatic from the Startup type: dropdown and click Start from Service status:. Make sure it now says Service status: Running.
  1. Configure Git to use the Windows 10 implementation of OpenSSH by issuing the following command in Powershell:
git config --global core.sshCommand C:/Windows/System32/OpenSSH/ssh.exe

Using cec-client on a Raspberry Pi to control TV power and inputs via HDMI

Using cec-client on a Raspberry Pi

Most modern HDMI connected devices support Consumer Electronics Control (CEC). It allows devices to send commands to each other, typically to get the TV to switch input and control volume. If you have ever turned on a Game Console and had your TV automatically change input to that device you have seen CEC in action. It is very convenient and useful, sort of a universal remote that works.

Every manufacturer seems to have it’s own branding of CEC (e.g. Samsung Anynet+, LG SimpLink, Sharp Aquos Link) but it may need to be enabled. Check your manual for details.

Using a Raspberry Pi connected to a TV that supports CEC, you can use the command line cec-client application to control the inputs and the TV itself. These are notes on how to use cec-client and understand the different options.
