How to update BIOS on AMD Ryzen motherboard – the hard(ware) way
As we know AMD motherboards need BIOS updates to support new generations of Ryzen CPUs. This can normally be done using a recognized older gen CPU to power on the board and access the built-in BIOS updater function.
When there’s no older gen CPU around to use or you’re simply in the mood for some hardware tinkering, you can get your elbows dirty (figuratively, since the board is brand new and not dusty yet) using an EEPROM programmer.
How to monitor progress of a dd operation
By default dd doesn’t display any status information while performing its operation. Newer versions include a status parameter which can be used to activate progress output.
How to pre-configure Raspberry PI for remote SSH and Wifi
Many Raspberry PI projects are used headless (with no display device attached or if a display device exists, it’s not connected to the default HDMI or analog outputs).
In these instances it’s time consuming to connect the PI to a monitor and keyboard just to configure remote SSH access and wireless connection details (and in rare occasions it may even not be possible).
Luckily, the good folk developing Raspbian implemented shortcuts and workarounds that allow things to be pre-configured even before booting the PI.
How to backup hard disk removed from RAID volume
After migrating a RAID volume to new disks it’s handy to keep a full partition backup around.
For this we can use partclone, a handy smart backup utility which is capable of recognizing multiple filesystem structures and then save only used data.
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.
With a rooted device there’s no limit on what you do on the device you paid for, but in case you’re stuck with a non-rootable device there’s still a chance you may force disable or remove apps.
