How to build global radiation monitoring network?



Joi Ito

This photo is Joi Lto (伊藤 穰一), he is a Japanese-American activist, entrepreneur, venture capitalist and Director of the MIT Media Lab (from his wikipage).

March 11, 2011, when the 2011 Tōhoku earthquake and tsunami happened, he was just chosen to be the new director of MIT Media Lab, but his wife and family still in Japan at the very moment. He wanted to know the status in Japan eagerly, but despaired by the government and media. They just couldn’t  provide enough information , immediately and accurately.

So he went to Internet try to figure out how to measure the radiation by himself, and found a lot of other people just wanted to the same things. Then they loosely formed a group call SafeCast, they measure the radiation and public the data to everybody else.

Now after 3 years, Safecast have 16 million data points, these data mainly from Japan.

And rest from a lot of other countries.

And you can see these is not so many data in China yet.

From the map and data you can see most of Japan is very safe just like other countries, Because I have a trip plan to Japan, I am very glad to know it.

How to build global radiation monitoring network?

If you ask government, they will tell you this need a lot of money and time, and after some very long time, they maybe can provide you some just hundreds of points just in one nation and will cost a lot of money to maintain these stations forever.

What is the different? Internet.

Internet make the information can free transfer, so people in different place in different country can cooperate with each other to do great things.

At his speech, he talked about a lot of other useful and interest informations, so please enjoy this speech:

TED: Joi Ito: Want to innovate? Become a “now-ist” – Joi Ito (2014)



Leadership makes people to cooperate, authority only makes people afraid



People always mix up leadership and authority, like someone in MasterChef, because he win a competition, so he was given the authority to be the team leader of next competition. But he didn’t have any leadership, any ability to cooperate with his teammates.

But when a team of people didn’t have leader, they could hardly to do some complex works need cooperation. So, finally some other guy stood up become new team leader , he didn’t have the authority from the judge of this show, but he have the leadership to make his teammates union.

People always think something, someone or some company associate with computer, software or network, are some kind of rocket science. But in fact, technic team also need teamwork, need leadership.

I have ever worked with some good software teams and some bad teams. There isn’t always bad engineer in bad teams. Some bad teams own some all star team members. Some of them have great program skills, have a lot of experiences. But at the bad team always have some fight, from what framework to use, to how to start or push forward.

People need cooperation, when we can cooperate with others, we can produce more and achieve something we can never do alone.

But sadly in China, people find hard to trust others, if you want to eat health even just eat safe, you need cook by yourself. I can’t imagine our future.

Simon Sinek: Why good leaders make you feel safe

An inspiring TED speech about binary data visualisation method

How to quick find the specific kind data from a lot of unreadable binary bytes? If you want to hack some system or quick find some import or relevant information, this kind method may have some use for you.

Chris Domas provide a method to visualise binary data, in this method music data looks like this:

Code looks like this:

These are English text, Russian text, Photograph, Clipart, ARM Code & x86 Code look like:

I think this is a great method. When smart people do something, they will try and try, try hard to find a smart way, an easy way, so I think that is why they can do it better and better, and finally let others think this is a magic.

Enjoy this speech.

The world is one big dataset. Now, how to photograph it …

This is a very great TED speech:

The world is one big dataset. Now, how to photograph it …

Why USA is the most great country in the world, I think is because the freedom, because sky is the limit, any people want to change world can try to, this country give people chance to try, to fail, and try again.

Make this kind private satellite in China is unthinkable, government will think you as spy. Make SpaceX government will think you try to make some weapon toagainst them. And some business man try to cooperate with government recover petroleum, but when the oil field really start to produce, local government force acquire these private petroleum company’s property.
