Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

This was tested on a ThinkPad P70 laptop with an Intel integrated graphics and an NVIDIA GPU:

lspci | egrep 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GM204GLM [Quadro M3000M] (rev a1)

A reason to use the integrated graphics for display is if installing the NVIDIA drivers causes the display to stop working properly. In my case, Ubuntu would get stuck in a login loop after installing the NVIDIA drivers. This happened regardless if I installed the drivers from the "Additional Drivers" tab in "System Settings" or the ppa:graphics-drivers/ppa in the command-line.

Generating Authy passwords on other authenticators

---

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

---

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

This is a guide for getting LineageOS (an older and unofficial version) onto an Amazon Fire 2015 7" tablet (also known as the 5th generation 7" Amazon Fire or under the internal codename "ford").

NOTE: This guide was originally written before someone figured out how to unlock the bootloader. There is now a newer method. Here it is very briefly. The old guide can be found below.

Unlocked bootloader method

First unlock the bootloader using this guide.

Once you're booted into TWRP download the latest LineageOS 14 release for your device here.

Although Microsoft does not support Windows XP updates any more, I'm sure there are still many users using it due to their personal habits or job demands. Therefore, XP's product keys may be necessary even now. Here lies the most comprehensive list of Windows XP product keys.

The following CD keys are official and original from Microsoft, mainly used for Windows XP Professional Service Pack 2/3 VOL/VLK system images, which are the easiest ones to find on the Internet.
