If you do a lot of sysadmin work, choose a topic that interests you, and find some kind of chart or table or data set that you would like to memorize. For example, you could choose capital cities and states, countries and their capitals, wire gauge to diameter, etc.
After a while of using that password each time, you will be able to remember all kinds of esoteric table data and amaze your friends at cocktail parties when you can recite the capital of every country on the globe, or what year many famous scientists were born.
Since you have to spend the effort remembering data, why not make the data something useful that you would like to remember for other applications?
Tablets are fun, show-off things that you use to waste time (though just like netbooks, they really suck for gaming). But you can actually get work done on a netbook and a good one will cost you less, too. Sorry, tablet fans, but that's how it is. They may be super cool to you and you think that you paid 500 bucks for a great thing, but you know in your heart that you paid 500 bucks for a goof-off device.
Not unless you count ALL web browsing as a waste, most email, and perhaps reading in general. Let's see, I also have spreadsheets that I keep (and maintain) on my iPad, To Do lists, Keynote presentations (admittedly created on my Mac), a calculator, financial information programs, sketchpad, and a thousand research PDFs (Papers), and yes, games. Sure, I won't be running R on my iPad, but I can easily do my thinking and research on it... And goof-off when I need to.
All in a convenient form-factor, free from the awkward, desktop-inspired keyboard, narrow-view screen, and short battery life of a netbook. Freedom from the desktop/laptop/netbook awkwardness is a feature.
Better sound quality?
Buh? An iPod is capable of providing higher quality audio than any of the internet radio streams offer, so what are you talking about?
And you do realize that "obscure" and "secret" have different meanings, right?
In a usual encryption scheme, the algorithm is public (or possibly obscure) and the key is secret.
With physical access to the device however, you can't really do better than obscurity, although some physical devices are really well protected.
the only metric that really matters (amount of sunlight over land per capita)
There are a hell of a lot of people in Africa who think there are some problems with your metric.
They are lying threw their teeth if they say nothing unusual happened. I watched it on fold on my trading platform and it was like 1/2 the market just turned off while computerized trades relentlessly sold to the nonexistent buy side. In the end its likely that the only people who got hurt by this were retail investors who trade with stop-loss or trailing stop-loss orders.
If they put an order in, they do not have my sympathy. They missed out on an opportunity, but they got what they asked for in order to do it.
How is that anybody's fault but their own? Sales don't happen unless the bid and ask prices match.
