Can’t set default app for .blend file on Windows 10

Problem: Can’t set default program for .blend files to Windows store version of Blender

Usually is not a problem as you’ll get asked if you want to set a default program. When you hit yes, blender does not show up in the list of apps. That wouldn’t be a problem, except Blender is from the Windows Store, so there is no launcher in the ordinary places.

Resolution: Install regular Windows installer from Blenders website.

Other Info

Not sure if the issue is with the Store or Blender. The .blend file type does not show up in the Windows Settings under “Apps -> Default apps -> Choose default apps by file type” and Blender doesn’t show up under “Apps -> Default apps -> Set defaults by app”

Setting up Proxy over SSH with Putty on Windows

What we are going to do is create a proxy using ssh so we can tunnel our web traffic in Firefox through it.

First, launch putty and setup a SSH connection like you normally would.

Next, in Putty, go to the Connection, SSH, Tunnels.  Set source port, change to Dynamic, and add.  In this example we are using port 1880.

After you have it set, Open the connection and log in.

Now go to the Proxy settings in Firefox.  You can open new tab, type about:preferences, hit enter, search proxy.

Set to Manual proxy configuration, then under SOCKS Host put localhost and the port number from Putty above, 1880 in our case.

You should now be running over the proxy, can test by running a whats my ip address.

This can be particularly useful in cases where you need to access a local IP address range on something like a Ubiquiti radio or router.  Or you need to check something from a different IP address.
