During the holiday break I started thinking about building a little mining-rig using some Raspberry Pi devices. During the holiday break I normally don’t have access to a PC, so I couldn’t do much apart from some research using my mobile. I came across a post titled ‘Mining Monero XMR Crypto Currency on Raspberry Pi’ by AndyPi. This post detailed how to setup a Raspberry Pi to mining XMR using Minergate mining pool and since I am already a user of the Minergate services it sounded like a perfect match.

Next step was to make a list of hardware required to built the ‘mining-rig’, giving me the following list of items to be purchased

Tech bought

• Synology DS916+ (March 8) as replacement for a Drobo
• PS4 Pro (April 29) as replacement for the XBOX 360 Elite
• Nintendo Switch (June 17)
• Logitech MX Master 2S (July 6)
• Iiyama ProLite E2283HS-B3 21” display (September 15)
• AirPods (September 16)

Last year July I wrote about how I connected some internet services to help my dad make it easier to get access to his electronic news paper and magazine subscriptions. Over that last year his memory has been slowly getting worse making it even harder for him to remember making very minor computer related hiccup an unsurpassable hurdle for him.

Over the last 12 months the process detailed in the post ‘Helping out the old man’ has been working fine for most of the time. Occasionally I had a re-authorize IFTTT again for Google Mail and Dropbox, but nothing serious. But for the last couple weeks things started to break down and I haven;t been able to fix it using the services used (IFTT combined with Google Mail and Dropbox). For some reason saving attachments stopped working, by either not saving anything at all or saving and image instead of the attachment.

Since moving to an SSD drive space is a limited resource. For several development tasks I am using a virtual machine whose disk image (dynamically allocated storage) has grown to approximately 45.5 GB. To free up some space quickly (relative term) I decided to shrink this particular disk image.

At the time of this writing the VirtualBox tool ‘modifyhd’ of VBoxManage only supports the disk format ‘VDI’.
