Optic illusion at Google Calendar & the science of murder

For several weeks, until yesterday I saw that certain national holiday was automatically marked in Google Calendar as being June 2nd.  May 12th (yesterday) was marked as a regular working day.  This was wrong, it was the opposite.  And as a result of that mistake, I even showed up for work at the office.

Today I open again my Google Calendar, and now that national holiday is correctly marked May 12th, and on June 2nd there's nothing.  What the hell is going on here?

In other news, yesterday I was watching The History Channel.  They were presenting some program about weapons of mass destruction.  At one point they talked about a 50 megaton (equivalent to 50 million tons of TNT) bomb the Soviets tested who knows when.  They said that this bomb is so powerful it can cause third degree burns within a radius of 64 miles.  I wonder what kind of lunatic would deem it necessary to inflict this degree of devastation?

In another part of the same program, they talked about chemical weapons, and said that at some point --and presumably now a days too--, the US and the Soviet Union had enough nerve gas to exterminate every single human being on this planet, each.  I mean, why?  Why do they need nerve gas for six billion people when their potential enemy's population is only a few hundred million?  Is this just to line the pockets of the gas manufacturers?  This is sickening.

By the way, I wonder how come the country with the world's largest stockpile of nuclear weapons has the moral authority to go tell other countries that actually, nuclear weapons are a bad thing for them to have?  Do as I say, don't do as I do, huh?  Yeah, I agree it's not a good thing for North Korea and Israel to have nukes, but the US is in no position to be demanding other countries disarm.  What?  You say it's required to defend democracy?  Oh thanks, now I see the light!
