Somewhat ridiculous ways to calculate PI number

I've found description of experiment to calculate PI number as a result of physical Monte Carlo simulation by shooting shotgun pellets over quarter of circle marked inside square. At least it is great visual explanation how to calculate PI.

I remember that I saw other technique using pins tossed over parallel lines. I've searched that and found something much more ridiculous: Calculating Pi by Throwing Frozen Hot Dogs

I don't dare for searching any more of that today...

Real life stories behind bug reports

I've found some gem, while browsing through Android reported issues:

My Nexus 10 was on silent mode this yesterday at church. I was using the YouVersion Bible app, taking notes. All of a sudden my Nexus 10 let off a shreaking siren type noise that couldn't be silenced. My church (of about 1500 people) all heard it, it stopped the pastor mid-sentence - as I ran out of the auditorium. Has anyone else experienced something like this? I don't think I can ever trust it to be quiet - in a quiet place again.

It shows also why some environments have distance to newest technology.
