Recently purchased a new combo wireless and Bluetooth multimedia keyboard for use with my Raspberry Pi 4.
Love the new keyboard, but sadly, even after adjusting the mouse pointer speed to the Max Speed under Preferences / Keyboard and Mouse it is still too slow for my sanity.
Luckily, their is another way to increase the mouse speed.
The following Terminal command will show you what software packages are currently installed on your Raspberry Pi 4.

For those serious about security on their Raspberry Pi 4 computers, regularly clearing the terminal history or bash history is advisable.
A chronological history of your entered terminal commands is automatically retained, which is great when you need to repeat or lookup a prior command. However, this can also become a security concern. What if someone gains access to your machine, opens a terminal window, and browses through your terminal history? If you are human, no doubt you will have (at some point) accidentally entered a password in a non-password field.
This article will show you how to quickly and easily clear the history of your terminal window.
Introduced with the May 2020 Raspberry Pi OS update was a new Bookshelf application helping you find and read books and magazines from Raspberry Pi Press. While interesting, this is not something I personally need or want. Thus this article will show you how to remove Bookshelf from your Raspberry Pi 4.
