Imagine a sidewalk that generates electricity from footsteps; this guy[^] might just make it happen.
Apparently, any source of vibration becomes a potential energy supply, to be harvested by this technology. Just imagine if a sheet of this material was installed under the mattress of every bed in every motel that charges by the half hour... There'd be no more need in all the world to burn another drop of whale oil for light.

I think there is a scifi movie [^]related to that.

You mean people still walk?
I think they should apply this technology to the surface of every smart phone. The things would probably be able recharge themselves.

How about light from opening envelopes?
Close a self seal envelope and let it set for a while.
Then in a dark room open it by pulling the sealed flaps apart.
You will see a blue/grey glow for a split second.
Tribophysics!
It is the crystals rupturing and releasing energy in the form of electromagnetic radiation.
Do you know the first person to ask Professor Frank Close about this?
Yep, it was me and he had never heard of it before.
(I was also the first person to ask him what the speed of gravity is and he said it was a very interesting question, then moved on without answering it. 20 years later he published The Cosmic Onion in which he stated he had spent 20 years thinking about the speed of gravity before declaring it as c. He sent me a signed copy of the book).

That is a very interesting question. Somehow I think it's faster than "c". In fact, I think it's instantaneous. But WTF do I know?

You'd think so =, wouldn't you? Unfortunately, experimentation says otherwise: http://www.csa.com/discoveryguides/gravity/overview.php[^]

Well, blow me down and tie me in a knot!
That's fascinating, and believe it or not a very understandable read. And the "experiment" makes sense.

I like it when someone can write up a serious experiment like that without having to use technobabble just to make themselves seem knowledgeable and ends up with a description you can understand without needing to know the theoretical math behind it (because that makes no sense to me at all these days and in extreme cases turns my brain off!)
It's a good description of a good experiment!

Could be a great benefit in first year of marriage after that it would be of minimal use.

Yeah, if you turn it on. This was in the Insider News aa couple of days ago: http://www.codeproject.com/Messages/4742935/Speech-recognition-hack-turns-Google-Chrome-into-a.aspx[^]
You have to actually give a website permission to listen, and then it isn't shut down properly.
My solution: unplug the microphone. Works fine...

I don't read Insider News often and I honestly didn't see it. I got the link from Facebook.
Unplugging the microphone may not be an option on all devices. On a laptop, you can disable the microphone, but on tablets and smartphone, I don't think there is an option.

There is an "emergency" microphone reset, but it requires special tools:

Yep, it's lovely how they fuq it up directly, but disable NPAPI (without a replacement) just because is old. I wonder why they don't obsolete Win32 altogether. Or at least LoadLibrary.

An elderly couple had just learned how to send text messages on their cell phones. The wife was a romantic type and the husband was more of a no-nonsense guy. One afternoon the wife went out to meet a friend for coffee. She decided to send her husband a romantic text message and she wrote:
If you are sleeping, send me your dreams.
If you are laughing, send me your smile.
If you are eating, send me a bite.
If you are drinking, send me a sip.
If you are crying, send me your tears.
I love you.
The husband texted back to her: "I'm on the toilet. Please advise!

Glad you enjoyed it Espen.
It gave me a good chuckle when I read it and thought it would be a good share.

Simplify (x & ~y) > (~x & y)
I quite liked how it just works out, and it's a nice little puzzle assuming you haven't seen it before, not so hard that it'll cost you your weekend, but good enough to tease your brain for a couple of minutes.
The comparison can be taken as signed or unsigned.
ps: I actually needed this thing today, but the other way around. I had to compute what this thing simplifies to, but only had x & ~y and ~x & y available.
