Navigating the modes of Vim

This diagram illustrates navigating through Vim’s modes. It was built factoring Vim 9 (i.e., all its modes, including up to two new modes, cr and cvr, in November 2023). Information about the state() and 'showmode' is provided too.

SVG version

Some features are only available in the SVG version. It is not provided directly from within this gist’s files because SVGs do not always play nicely in GitHub (particularly, refusing to display embedded fonts).

The SVG version includes hover text help, which shows pertinent information about the underlying key, command, mode, etc.

Every Mention of Gazebo in the ROS Weekly Update

Having heard about the new camera driver built into the kernel of the new Raspbian OS image, I decided to have a play, using my PS3 EyeToy camera. The steps below are based on this forum thread, with some changes to reflect my own experience. The Raspberry Pi supports a number of cameras, not just the EyeToy, so if you have a spare one lying around, give it a go.

Install the ‘motion’package:sudo apt-get install motion

This should automatically install the required ‘ffmpeg’ package – if not you can just do sudo apt-get install ffmpeg.

Edit the config file:sudo nano /etc/motion/motion.conf

To enable daemon mode (so you can run the software in the background without it tying up your terminal):daemon on
