comment Meaningful thumbnails for a Video using FFmpeg
To avoid boring images such as plain black and white: generate more thumbnails than you need, compress them with jpeg, and choose the images with larger file size. This works surprisingly well by itself to get decent thumbnails.

comment Meaningful thumbnails for a Video using FFmpeg
My approach is to generate perhaps a dozen jpeg thumbnails at different times, and choose the one with the largest file size. The largest file tends to be more "complex" and interesting, it would seldom be a blurry image, and it will never be a boring image such as a plain black frame. This approach might not be ideal for you, but perhaps you can use it together with other methods.

comment How can I invert all the display colors in Windows Vista?
@Yaurthek, thanks for your work. I noticed you said your app doesn't work on XP. F.lux and redshift do work on XP, so I guess it is possible to invert the screen on XP also. Here's a relevant link: jonls.dk/2010/09/windows-gamma-adjustments Perhaps you could try that technique with NegativeScreen? There's a demo app here: nirsoft.net/vc/change_screen_brightness.html I wanted to write a shorter demo but my windows build env is broken and I don't have time to fix it right now!

comment What is the origin of the UNIX $ (dollar) prompt?
I guess the root prompt # is so chosen to coincide with the comment character, reducing the chances of accidentally pasting dangerous commands... or maybe not! I don't think they had much in the way of cut-and-paste back in the day.

comment Reformat SD card to NTFS
Does windows format an SD card with NTFS "correctly", i.e. using the right settings for good performance on SD media? As far as I recall, the filesystem proper should start at the 8MB mark, and there might be other issues. I guess if you use the existing partition this would be less of a problem than starting from scratch with running fdisk.
