The Challenge For The Dragon

Here’s an article describing the pre-rendezvous testing that it will go through. This is misleading, though:

“This is pretty tricky. And also, for the public out there, they may not realize that the space station is zooming around Earth every 90 minutes, and it’s going 17,000 mph,” said SpaceX CEO Elon Musk. “This is something that is going 12 times faster than a bullet from an assault rifle. So it’s hard.”

The velocity relative to earth isn’t really relevant, and doesn’t make it harder. All that matters is the relative velocity between the spacecraft and the ISS. And that, of course, is what they have to demonstrate their ability to control.

Political Correctness

Run amok:

The race of the gang members themselves isn’t an issue, but their religion and associated cultural attitudes, and the racism that these foster, are. The fact that in this case, as in previous ones, the perpetrators were Muslims, and from parts of the world where extremist forms of that religion hold sway — eight of the Rochdale gang were of Pakistan origin and the ninth was an Afghan — has absolutely everything to do with the case, and it’s just one uncomfortable aspect that liberals don’t want to confront.

Another is the fact that politically correct attitudes to all things “racial” among the relevant authorities meant the victims’ ordeals went on for years longer than might have been the case. Many of the victims were from broken homes and under the supervision of social workers, but when they reported abuse to their carers, the police and prosecutors failed to act because, it’s claimed, they were “petrified of being called racist.”

There are also broader social issues arising from the case, and others like it, that liberals would prefer not to discuss; in particular how decades of liberal social polices on everything from immigration to welfare have helped to create the environments in which these crimes can be committed.

It’s a tragedy to watch a culture commit slow suicide.

One Of The Many Reasons That Facebook Sux

And yes, I know it’s the eve of the IPO. Ask me if I care.

First I get an invite from someone to friend them. I’ve never heard of them. I go to the Facebook page, and there’s no obvious place to see where people who invited you are. And when I follow the link in the email with the invitation, does it take me to that person’s invitation? No. Of course not. It takes me to the page of suggested friends and invitations, and I have to scroll down to find this particular one. There is absolutely no excuse for any of this in this day and age of web technology.

But wait! It gets worse.

The guy who invited me has zero information about himself publicly available, which is OK, I guess, but I still have no reason to accept FB friendship. It doesn’t even show me if we have friends in common (though maybe the fact that it doesn’t do that is a sign that we don’t, but it would be nice if it were more explicit). So I look at the options for dealing with his invitation. There are two. Delete invitation, or accept it. There is not option (c), which is the one I want, which is “Send an FB message to him to ask him who the eff he is, and why I should friend him”.

Really, folks, does it have to be this hard?
