Make Animated GIFs with ImageMagick

There’s been a recent resurgence in animated GIFs. Maybe it’s because they’re easier to share on GitHub, Imgur and Twitter. Videos usually need a player and don’t work everywhere.

Windows 10 IoT Core Public Release for Raspberry Pi 2 – Install and First Impressions

Edit: In case it’s not clear from the below; Windows 10 IoT Core is nothing like the desktop Windows you may be used to. There is no desktop. There is no shell. It doesn’t run normal Windows applications or MS Office. It is only really useful to give you access to the GPIO (and custom … 

 

How to Watch BBC News Videos on a Desktop Without Flash in Safari
