The relatively new Android mobile cell phone from Doogee called the X6 has its multiple user account capability disabled. The operating system is an old and non-standard Lollipop 5.1 Android, but the multi-user option should still be enabled in a phone of this operating system release. Below are a few simple steps to enable it. A prerequisite is installation of the Android Debug Bridge (ADB)

Finding information on setting up the Grandstream Handy Tone 503 (HT 503) analogue telephone adapter (ATA) for the UK on Virgin Media telephone network was a difficult and time consuming task. An overall summary is available for FreePBX. The specific settings were not covered and are summarised below.
My Roomba 560 seemed shy as it was backed into a corner with a dead battery every time I came home. So, as I had done many times before, I cleaned all the LED sensors under the bumper and fitted a new battery. No change. I eventually found this site about the nine beep dance of death. Ah, more dust in the sensors, I thought. Testing showed the faulty right bumper switch. Taking it apart I was pleasantly surprised by the use of optical rather than mechanical switches. Still, dust could still be a problem.
I migrated a virtual machine running the Apache 2 web server software on Debian wheezy GNU/Linux from Bytemark's legacy virtual machine infrastructure to their new BigV infrastructure. Staging this on my internal virtual infrastructure worked without a hitch. However, on the true infrastructure, Apache failed to start on boot with the following message. It would restart without issue if I then logged on and started it manually.
Neon indicators on electrical items do not seem to last for a very long time. They just blacken. A LED would be a good replacement, but they do not work directly with mains AC voltage. Here are some options to consider.
Following on from FoundationDB's graph store, they are now proposing a document store. Again, there is emphasis on 'ACID' compliance. So, unlike most other newcomers to the database scene, their database will support the protections familar to RDBMS database administrators. The database should be protected from interference and corruption, and benefit from protection of saved transactions.
This brief HOWTO shows how to take a working 32 bit 14.04 installation and convert it into a 64 bit system. You will be able to keep all your programs, settings and data. You start with a 32 bit system that can run 64 bit programs, then convert it to a 64 bit system that can run 32 bit programs.
With the release of Ubuntu LTS 14.04 (Trusty Tahr), the ability to use the multiarch facility to upgrade to 64 bit is easier than ever. Much simpler than upgrading 12.04 and an evolution of upgrading Debian 7 or 8.
Lots of issues with Gnome after upgrading Ubuntu GNU/Linux from 12.04 LTS to 14.04 LTS. The fix for most issues is to first login with the Ubuntu (Unity) session before choosing another session.
Anyway, hibernation ceases to be available after the upgrade.
