Set up XRDP on Ubuntu 18.04 LTS

This was suprisingly non-obvious. Key clues:

# initial setup
sudo apt update

Adapting IPFire net-to-net client config for OpenVPN in ASUS WRT routers

IPFire supports net-to-net connections.

Part of setting up the connection with non-IPFire peers often involves generating a .ovpn file from the client package.

There are some client docs about how to do this, but not net-to-net.

For net-to-net clients, IPFire generates a zip file containing two files. Both files are named based on the name you choose for the VPN.

Make PSpice for TI work in conjunction with Git for Windows

I recently installed PSpice for TI (version 17.4-2020 S002 Windows SPB 64-bit edition).

After installing, Git for Windows bash no longer worked as expected. Instead of starting up in my home directory, it started up in the (emulated) root directory; and it didn't load my profile. (In other words, installing PSpice for TI broke my Git for Windows installation.)

Investigation revealed that the installation had created an environment variable HOME in my profile, with the value c:\mcci\projects\SBP_Data. It was easy enough to fix this.

I needed the list of supported languages for highlightjs, used by Markdown code fences (```).

There is a list at https://highlightjs.org/usage/, but was not readable. But it looked like markdown, so I grabbed it and made a markdown table.

Language	Classes	Package
1C	1c
ABNF	abnf
Access logs	accesslog
Ada	ada

Convert RTX-Blinky from RTXv4 to RTXv5, and add UART Example

There is no example for using a UART in conjunction with RTXv5 as of this writing. This gist presents an adapted example that was tested in conjunction with Keil V5, RTX APIv2 and the Blinky example.

Create the project

Create the RTX_Blinky project in a spare directory using the "Pack Installer" button.

Press the pack installer buttong.
In the left panel, select Boards and select MCB1800>Devices>LPC1857.
In the right panel, select Examples, and then "CMSIS-RTOS Blinky (MCB1800)". Press the [Copy] button.
Select someplace to put the files. The Keil IDE will create subdirectories from this directory. Avoid using an existing location!
