How to disable/remove unwanted apps from Android (no root)
Some manufacturers bundle a lot of unnecessary and sometimes even suspicious apps with their devices. Some can still be uninstalled or disabled, but for those specific apps that the manufacturarer wants to force on the user these actions are not available.

How to adjust TLER value on hard disk (for data recovery)
In case the hard disk itself is taking too long to respond, some operations will fail and can cause the controller (software or hardware) to drop the disk out of the RAID. Even when no RAID is used, the hard disk itself can still spend too much time retrying a (failing) read, causing unwanted delays and possible further damage. To alleviate this, you can try to use a feature called TLER (Time Limited Error Recovery) or CCTL (Command Completion Time Limit).

Migrating CentOS 7 to PHP 7
CentOS is a conservative distribution giving you the most stability and security, at the expense of newer features like the latest PHP release. Fortunately there are ways around for getting a newer PHP by using one of the several repositories out there providing updated packages. My personal choice for this task is Remi's Repository.

How to disable/uninstall problematic Magisk modules
Magisk is a great solution for customizing (rooted) Android devices via modules without modifying the firmware (much...). Magisk modules are easy to install and activate (through Magisk Manager), however in rare cases when something fails you can end up with a bootlooping device. In such instances you can either resetting/reflashing the device or use the handy Magisk module installer tool.
