Synology Hyper Backup Options and Pricing

The Synology Hyper Backup app allows owners of Synology NAS devices to easily set up backups to various cloud services.  However, one thing that isn’t shown in the app is the pricing of each service.  So here’s a pricing comparison (prices as of Aug 4, 2018). Synology C2 Location: Frankfurt, Germany 100 GB = €9.99/year (approx. USD $0.0100/GB/month) 300 GB = €24.99/year (approx. USD $0.0081/GB/month) 1 TB = €59.99/year (approx. USD $0.0058/GB/month) 1+ TB = €69.99/TB/year (approx. USD $0.0068/GB/month) Amazon S3 Location: Many, using U.S. (N. Virginia) to compare Pricing: Complicated – only comparing standard S3 storage costs here USD Continue Reading

Desktop Computer Upgrade

I last posted about my computer specs six years ago when I first built my VMWare ESXi Whitebox server.  Here’s an update to what happened to it: From the software point of view, it was all and well for the first 2-3 years.  I had FreeNAS, Windows 7 and Windows 8 virtual machines running on it, and some lesser used Ubuntu virtual machines for playing around.  With the IOMMU capabilities of the motherboard, I even was able to get the GPU accessible by the Windows virtual machines to use it as a desktop and even play some games on it.

Enterphone intercom anywhere

My apartment building has an old hard-wired Enterphone intercom to buzz visitors in.  This poses a slight annoyance since the dependency of the phone line in conjunction with a conventional corded telephone means I have to walk to the phone in order to answer the intercom. Given the low rate of visitors and the small size of my apartment, in retrospect, this isn’t really a big deal.  Most normal people would just buy a cheap cordless phone and call it a day. But that only helps if I’m in the apartment.  What if I wanted to be able to buzz Continue Reading

Delaying a MacBook Pro’s deep sleep

I bought a new mid-2012 non-Retina MacBook Pro late last year, immediately prior to the line being discontinued (I still think the second-generation MacBook Pros were the best series).  After about a week, I found an annoying thing with it:  When I turned on the computer after coming back from work, it seemed like it almost always required a cold startup after sleeping, where the optical drive initialized and did its buzz, and took a lengthy 10-15 seconds to wake up from sleep.  Also, the computer would wake up (and the optical drive buzzed) even if the MagSafe charger was disconnected.

Basic ‘ZFS on Linux’ setup on CentOS 7

Here is a quick guide to getting a plain ZFS partition working on a Linux machine using the “ZFS on Linux” project.  I was playing around on a CentOS 7 virtual machine trying to set it up as a replication target for my home FreeNAS box as a backup.  If you are unfamiliar with ZFS, it is a filesystem for a storage environment, having features such as data integrity protection and snapshots; I came across it as it is used in FreeNAS. Here is the procedure I used:
