Simple Simhashing, My favorite trick.

Knol got equation editing a few days ago, and to celebrate I've written up a knol on one of my favorite CS tricks, simhashing using sets. It's a technique I picked up at Google, and it's extremely useful for grouping together similar things in a large dataset.

Suppose you have a huge number of items that you would like to group together by a fuzzy notion of similarity. Suppose the only tool available to you is a key-value store. Suppose you only have the resources to consider each object once. Never fear, simhashing is here!

Things I Support

No matter your political beliefs, if you value freedom you can support this group. They are dogmatically consistent in their support of personal freedom, even when it conflicts with public opinion and common sense. They ask the questions that should be asked. As such, I support them even when I disagree with their position on any particular issue. They are as essential to the functioning of our society as the media.

It's unfortunate that the political issues surrounding the Boy Scouts of America have overshadowed the rest of what it does. It is responsible for more of my values and character than any other influence, and remains a fantastic organization. On the issue of permitting Gays and Atheists to be members, I consider myself part of the loyal opposition. As an Atheist myself and an Eagle Scout, I will support and participate in the organization so long as it will accept my support and participation.

The Nature Conservancy takes a unique approach to protecting wildlife. Their primary methodology is to simply take the money you donate and use it to buy land. Political progress is one election away from reversal, but the progress of the Nature Conservancy is as permanent as property rights.

A microfinance charity with a personal twist, Kiva matches lenders in the developed world with people whose lives could be substantially and permanently improved with a small loan. The loans are interest free, but you get your money back at the end of the term and improve someone's life in the process.

Freedom of speech is the most essential right. All others spring from it. In the US, we protect speech, even reprehensible hateful speech, more thoroughly than any other nation on earth. Many people aren't nearly so lucky.

Carriage House Farm
They provide fresh local produce, honey, and horse stabling to the greater Cincinnati area. If you are interested in the workings of a farm, keeping bees, the politics of local food and family owned farms, or just what produce will be available at the next market, check out the frequently updated blog.

This game is definitely the most fun I've had online, and I also worked on it! Imagine Starcraft where each unit is controlled by a human and you'll be pretty close to imagining this game.

It's heartwarming that an organization that believes in bringing all knowledge to everyone just by creating the tools to allow everyone to volunteer is actually succeeding at it.
