Fix for Older SSH Keys Not Working on Windows Git

If your old SSH keys are not working on Windows after installing the latest Git client and tools, and you're being prompted to login (~/.ssh/config configuration being ignored), the fix is to add the following line to the bottom of the C:\Program Files\Git\etc\ssh\ssh_config file:

Host *
	PubkeyAcceptedKeyTypes +ssh-rsa

That's it.  It will work again.

Running Multiple Channels of Audio Simultaneously in Linux

In Windows, I configure my Realtek audio to play sounds through my headphones (plugged into the front panel jacks) and my speakers (plugged into the rear panel jacks) simultaneously. I noticed in Ubuntu, the default is to mute sound in the rear when a device is plugged into the front. I wanted to stop this behavior, so here's what you have to do. Some people may also be looking to mute the rear speakers when a device is plugged into the front, so I have included both configurations. Download this nifty utility to manage and configure your audio settings by running these commands.

sudo apt-get install gnome-alsamixer
alsamixer

In this application, you can adjust volume and mess with several other settings.

At the bottom of alsamixer, scroll over to the "<Auto-Mute>" option.

To play audio through both headphones and speakers, change Auto-Mute to "Disabled".

To play audio through only one device, change Auto-Mute to "Enabled".

Hope that helps!
