You are probably watching video files with subtitles as embedded (or separate) text files (srt etc). This allows the video player to render them with any font and higher resolution.
Agreed, it is likely for the camera. A lot of blue dyes for water fountains and such are copper sulfate. Dyes for tanks or fish ponds are increasingly methylene blue, food dye.
I thought I would just extend the poster's thought experiment, not imply that magnets were indeed used.
I had the trouble of going to bed but my mind was racing with ideas, and I could not fall asleep. I noticed that taking a notepad next to bed and writing down the ideas or seeds of ideas I could get them out of my mind and my mind could be at rest and I would fall asleep.
I think it releases the mind from trying to remember the ideas in the morning. When I write the ideas down I can review in the morning with the benefit of having a good nights sleep.
I do this too. It's also worth buying a light pen to keep by your bed so you don't have to turn on a lamp and blind yourself. It makes getting back to sleep easier too.
I agree. I went back to pen and paper last year, just for thinking 'out loud' about problems and I could not believe how much it improved the quality of my programming.
This is about the lowest-end desktop you can buy these days. Combined with the netbook, it's much less expensive than a 16" Macbook Pro, for example. (That's why I can't get too excited about laptops. They are underpowered, un-upgradeable, and very expensive.)
