Q How can I identify the graphics card in my computer?
A (Thanks to Vladlenin5000 in the Ubuntu Forums) System Settings > Details
Q I have just allowed the installation of the VirtualBox update to version 4.3.34 (was on 4.3.10). All my Virtual machines now crash when loading, except for one Windows XP VM. The crash occurs at the point where the Windows Logo appears on boot-up. I tried using F12 and booting from the Windows 7 Installation CD but that crashed in the same way. I am on Ubuntu 14.04.
A (Thanks to ajgreeny and philchambers in the Ubuntu Forums) I have downloaded and installed the latest VB from the VB site (5.0.10) and that has fixed things.
Q How to block emails in Thunderbird mail? I am unsubscribing to as many mass junk emails as I can. However, sometimes the email doesn't have an unsubscribe option.
A (Thanks to Jim_deadlock in the Ubuntu Forums) Thunderbird has an adaptive spam filter, it “learns” as it goes. The more messages you mark as spam the more efficient it will become. Also, never “unsubscribe” from spam, it will just make it worse, just mark it as spam.
Q I'm selling an Acer Revo Aspire. It has only Ubuntu as an operating system, but I want to delete all my personal info before selling.
A Download DBAN, burn it to a CD, boot from it, run with the defaults, which will probably take a couple of hours. If you want your buyer to have an operating system, do an “OEM” install of Ubuntu: https://help.ubuntu.com/community/Ubuntu_OEM_Installer_Overview
Q I connected ipad to g5, and I opened ipad in Nautilus, and everything is ok. I have videos of about 3 GB space and I copied that stuff to the DCIM/100APPLE folder on ipad, but no video playing app recognizes anything, just like I didn't copy anything.
A (Thanks to TheFu in the Ubuntu Forums) Transcode the video files to a format supported by your ipad. Generally, that will be h.264/aac/mp4 files. There are specific settings required for Apple stuff to work. Handbrake is a tool which should be able to do it, and has presets just for Apple, but there will be a loss of quality, as all transcoding loses qualify.

Tips and Techniques Well, Darn
I didn't do anything interesting in Linux this month. Professionally, I'm looking at Windows 10 with a view to a corporate rollout in the spring. It's an accounting shop. The typical computer has almost 200 “applications” installed, and none of them run under Linux. (A potential client walks in and says, “I haven't filed a tax return for 12 years, and I have income in both Canada and the United States.” That's two dozen “applications” right there.)
At a personal level, my wife and I are seeking legal custody of her grandson, which requires quite a lot of work. He's a very bright eight-year-old who came from China a year and a half ago. We're looking after him, but need legal standing to make educational and medical decisions on his behalf. Our house got a lot noisier when he arrived!
My picture celebrates “Movember”. Look it up.
One thing I have noticed in Linux: Xubuntu 15.10 mounts my Android phone as an external drive, which makes transferring files back and forth much easier.
