Plus small tutorials on how to make them. This is a very nice list.

Selective Invisibility is

the moderation technique of hiding the activity of troublemakers and trolls from everyone but the troll themselves.

It’s been around longer than I thought. (via Waxy)

Very nice.

I was surprised that such a variety of designs would arise from a straightforward parameterization of this simple logo. But that’s often the case. This tiny corner of the design universe contains an infinity within itself. It’s like exploring a drop of pond water with a microscope. The universe within is dazzling.

Amazing.

As good design cannot be measured in a finite way he set about expressing the ten most important criteria for what he considered was good design.

A brilliant read.

A particularly enlightening comment:

Slow zombies are only scary because there are two thousand of them between you and your idiot girlfriend’s house across town (who you considered abandoning to her fate 3 times in the past hour), and you only have your grandpa’s shotgun that has been mothballed in the attic for 17 years, a handfull of shells, and the golf club you had to kill your childhood friend with. Zombie movies invoke the long term terror of having to deal with the fact that the only food you have ever made yourself was from a box, and figuring out how you are going to survive. It’s the horror of coming to grips with the fact that for the past 24 years of your life, you have never EVER been even remotely in a situation where you have had to kill a 10 year old boy and his mother with a baseball bat because they would have torn out your heart if you didn’t. Now you are in that situation for the better part of the day. They terrify you because there is a paper thin margin of error between you being human, and becoming one of them. A drop of their blood spraying you in your mouth is all it takes for you to turn into one of those abhorrent beasts. Not just you, but everyone you are surviving with. Every single one of your companions, who you RELY on for protection and survival, could turn into one of THEM at any moment, and you have to kill them before they become dangerous. THAT is what is scary about slow zombies.

If you can make the game that makes me feel THAT, you sir have my 50 bucks.

tl;dr Zombie game design is not necessarily easy.

Now you can use a simple <link> tag to let Google’s crawlers know the preferred URL out of the many URLs possibility that links to a single page of yours, to avoid duplicate indexed content indexing. Probably not of immediate need, because as Google mentioned before, there is no such thing as duplicate content penalty except if you’re doing shady things like stealing content from other sites.
