Cool, I just found out that Wikipedia has a Screenshot topic, listing how to take screenshots (and often shots of the current window) on many platforms, where (*) means I verified them:
Apple Mac OS X
(*) Use “⌘ Cmd+⇧ Shift+3” for the screen or “⌘ Cmd+⇧ Shift+4” for a part of the screen (as of Mac OS X Tiger, you can press the “Spacebar” to capture a Window in stead of part of the screen). You can press “Ctrl” with these shortcuts to the shot goes to the clipboard, otherwise it gets saved as a PNG file.
Microsoft Windows (*) Use “Prt Sc” for the screen or “Alt+Prt Sc” for the Window
(note that on my laptop and multi-media keyboards, you need to type the “Fn” key in order to press the “Prt Sc”)
Apple iOS
(*) Press the “Home” and “Lock” button at the same time.
Google Android
Hold the “Volume down” button, then press the “Sleep/Wake” button.
(*) Or press the “Sleep/Wake” and the “Home” button at the same time.
HP WebOS
Press the “Orange/Gray Key+Sym+P” at the same time.
Or press “Home Key+Power” at the same time.
The Android Security Team has built a tool, called nogotofail, that provides an easy way to confirm that the devices or applications you are using are safe against known TLS/SSL vulnerabilities and misconfigurations. Nogotofail works for Android, iOS, Linux, Windows, Chrome OS, OSX, in fact any device you use to connect to the Internet.
There’s an easy-to-use client to configure the settings and get notifications on Android and Linux, as well as the attack engine itself which can be deployed as a router, VPN server, or proxy.
This is probably because most of my iTunes consists of my own CD collection ripped as MP3 files, and the instructions about “clicking the cloud icon” got me in the wrong direction (I assumed cloud icons for each song would appear in the “My Music” Library, but none of the songs showed up that list).
They are referring to the “Purchased” under the “Quick Links” section on the right of the iTunes Store Home Page. Once you do this “Songs of Innocence” will be added to your “Purchased” playlist on the left.
What apparently happened was that I hadn’t accepted the updated iTunes license agreements yet, so the songs would not added to the library, even though they were “Purchased”.
Most things are simple when you know how to do it.
In this case it was to move the Dock to a different monitor (or to restore it to your main monitor when you accidentally moved it to a secondary monitor).
TbonesTech explains it in the below video, and it is this simple:
On the monitor on which you want the Dock to appear, move the mouse to the bottom of the screen.
Then wait a moment for the Dock to move to that location.
It works in Mavericks. It might work in older versions as well, but I’ve not checked that yet.
