Alpine Boot switcher
I boot from a USB boot drive using UEFI. Because of the UEFI boot, it just a matter of copying the files from the alpine ISO to a USB thumbdrive VFAT32 partition.

Hosting WordPress on OpenShift
So I finally moved my WordPress web sites to OpenShift. OpenShift is a cloud based Platform-as-a-Service offering from RedHat. And while there is a learning curve I would say that so far it works great. My implementation is a fully cloud based solution. Makes use of the following services: GitHub for code hosting ...
Resizing a Linux RAID
It is possible to migrate the whole array to larger drives (e.g. 250 GB to 1 TB) by replacing one by one. In the end the number of devices will be the same, the data will remain intact, and you will have more space available to you. Extending an existing RAID array In order to increase the usable size of the array, you must increase ...
