Gamepad Mouse on Raspbian

Use a USB gamepad as a Raspberry Pi mouse.
Raspbian supports mice out of the box, but what if you want to use a USB gamepad to move the pointer around (and click buttons) instead?
I'm currently using a Logitech Dual Action gamepad to control my Raspberry Pi running Raspbian Stretch. Here's what I did:

Install Packages

Install the following through Add/Remove Software or the command line (sudo apt install):
  • joystick - drivers and useful joystick/gamepad test programs.
  • jstest-gtk - windowed test program.
  • xserver-xorg-input-joystick - enables joystick control of windowing system
  • qjoypad - enables reconfiguration and remapping of joystick events.
This should automatically install dependencies.

Reboot.

Note: rebooting with mouse and gamepad both connected through the same USB hub seemed to disable both devices. So you may wish to connect at least one directly to the Pi.

Configure

My gamepad-as-mouse defaults to left-thumbstick for movement, and buttons 1 and 2 mapped directly.

If this does not suit, use QJoyPad to remap the joystick input.

You'll have to run QJoyPad it every session unless you set it to run on startup.

Troubleshoot

Use jstest-gtk from the joystick package to test if your device is being detected.

Note

I wrote this because I could find no other guides on the internet. Feel free to suggest fixes.

Transcode to PSP using Handbrake

Source: Handbrake 0.9.9.5530 64-bit edition Target: (Phat) Playstation Portable PSP-1000 , System Software: 6.60 Many internet articles on how to transcode video to PSP using Handbrake have not worked for me. Even the most helpful are incomplete. I hope this post will help fill in the blanks. There is no longer any PSP preset for Handbrake, but from what I can gather, the preset had only limited success as the x264 encoder would change syntax and settings between versions. Other presets that may have worked before, like 'iPod' and 'Apple-Universal' now do not. Here is what worked for me, step by step:

Firefox History Statistics - Extracting from Places.sqlite

If you want to take a look at Firefox surfing activity, the about:me add-on is a good start. However, it presents only one view of data and is thus limited in its ability to present more detailed statistics. We will view that data in a different program. So let's first extract it from the browsing history stored in the Places.sqlite file into a CSV file using a Firefox add-on. Step 1 - Locate and copy Places.sqlite to a working location On Windows machines, Places.sqlite is found in a directory similar to: C:\Users\User1\AppData\Roaming\Mozilla\Firefox\Profiles\ .default\places.sqlite Copy the file to another location. The database will be locked while using Firefox, and the SQLite plugin we will use to open it.

Bloomberg JSON data into Libreoffice Calc

LibreOffice Calc has no inbuilt stock market functions, and a popular plugin which offered those has stopped working along with changes to Yahoo Finance. Luckily, we can get the latest quotes from Bloomberg. [2018-12-15] Bloomberg Finance is, understandably, blocking multiple simultaneous requests. A more flexible solution is using a Python Stock Scraper .
