Database And Brain

According to "The Economic Meltdown of Moore’s Law and the Green Data Center" presented by The Uptime Institute Inc. in 2007, this year, 2009 is when 3-years-electricity-cost will be the same amount as server cost. And in 2012, it is expected to be doubled.

What does this mean?

If you are a facility manager, you must be very sensitive to energy costs today. But what about you, as an IT manager who develops software? Probably not. For your business requirement does not include energy costs.

But soon, you will need to take it into account if the cost is rising as expected. It's easy to get the whole power consumption just by plug it into a measurement equipment, but doesn't tell which consumes how much at all.

Fortunately, there're many studies available. But unfortunately, no practical tool/project available today.

So I will get started my project next month, which is based on the study, "Full-System Power Analysis and Modeling for Server Environments". An overview of the project is illustrated below.

Months ago, I got 3 Dell-T105 cheap boxes with AMD Opteron Quad Core and 4GB RAMs. So they look convenient to begin with.

For the time being, the project is only for Linux. And the main performance counter to use is PerfSuite.

Basically, there won't be any technical problems, but the question is if such a user community can be built. I guess the project could be runnable by revenues through ads from vendors.

But at first, let's see my boxes can show reliable results.

Vizoo, YouTube for graphs, got TechCranched. I have led the db design from scrach over a year.

Not yet in English. But coming soon!

Haruki Murakami is one of the most interesting writer in the world today.

As he often mentions, he likes Raymond Carver.

Once you read Ray's works, you never forget his taste. It is strange. In the begining, it looks normal, but in the end, it becomes totally scary world as if you got through to the other world.

Ray puts a little difference one by one. You can move on without paying too much attention. You can just put an ordinary image on the gap.

But if you do, you find it's hard to picture such a scene. So you have to imagine.

Then, in the end, you made up the story with bunch of images you had.

That is a blank or difference effect, I think. So you find something new whenever you read.

With this hypothesis in your mind, take a look at popular novels. They are filled with pictures, no blanks left.

You can enjoy for the first time, second?, third?, boring, boring, boring...

They are made to be consumed. While something with lots of blanks or differences is to be created in users.

Here, I see a significant difference. And it is a key, I think, to the coming world.

With such a concept, I made a search system, which will give you "How come? Ah-ha!" search experience. Available in 4 languages.

Examples are blogged here in English. Just try, and tell me what it is.

This world is changing. From the one "how to do" matters, to the other "what to do" does.

Then, problems people have are changing accordingly.

Answering to "what to do" is not something others can do or should do. But to make a decision on "what to do" makes sense when there's any change on its field.

"Chigai" is Japanese that means "difference". An interesting property of "Chigai" is not the difference itself, but the gap that tells A is different from B. So I could say, "Chigai" holds something new information that A and B do not hold.

A change is recognized as "Chigai". And then perceived or interpreted to get accepted.

With this "Chigai" in mind, to deal with the "what to do" era, Database that tells "Chigai" is making more sense. An interesting fact is that such a database can tell a new information that the database doesn't store.

Okay, so how we recognize "Chigai"? Some recent brain sciences answer to this question. By expecting what'll come next, and to which a reality is compared.

I love the concept "Chigai", and its interesting property that says a gap, 無(emptiness), holds the source of creativity.
