Codecademy is an education company. But not one in the way you might think. We’re committed to building the best learning experience inside and out, making Codecademy the best place for our team to learn, teach, and create the online learning experience of the future.

Education is old. The current public school system in the US dates back to the 19th century and wasn’t designed to scale the way it has. Lots of companies are working to “disrupt” education by changing the way things work in the classroom and by bringing the classroom online.

We’re not one of those companies. We are rethinking education from the bottom up. The web has rethought nearly everything – commerce, social networking, healthcare, and more. We are building the education the world needs – the first truly net native education. We take more cues from Facebook and Zynga in creating an engaging educational experience than we do from the classroom.

Education is broken. Come help us build the education the world deserves.

nukemap.jpg

The original NUKEMAP was created in February 2012 by me, Alex Wellerstein, a historian of nuclear weapons. I have a B.A. in History from UC Berkeley, a Ph.D. in History of Science from Harvard University, and I am finishing a book on the history of nuclear secrecy in the United States from the Manhattan Project through the War on Terror. At the time I created the NUKEMAP, I was an Associate Historian at the American Institute of Physics in College Park, Maryland. In 2014, I began working as an Assistant Professor of Science and Technology Studies at the Stevens Institute of Technology, in Hoboken, New Jersey.

Note: I am a historian of physics, not a physicist — people seem to sometimes get confused on this because of the subject matter I study and where I have worked. You can read more about my research on my blog, Restricted Data: The Nuclear Secrecy Blog.

In July 2013, I unveiled NUKEMAP2 and NUKEMAP3D. NUKEMAP2 allows for many more effects visualization options, and the display of casualties and fallout information. NUKEMAP3D allows for the visualization of mushroom cloud sizes in a 3D environment. In December 2013, I upgraded the blast model of NUKEMAP2 to account for arbitrary-height detonations. In April 2015, I performed a major algorithm upgrade to the casualty model to give it much finer-grade calculation of people over small areas and to generally increase its speed of calculation. NUKEMAP3D’s development has been put on hold after Google announced its deprecation of the Google Earth Plugin API, on which NUKEMAP3D relies.

The original NUKEMAP and NUKEMAP2 are both Google Maps “mashups.” This means that they use publicly-available code to modify the way that Google Maps data is displayed (this is the “Google Maps API”) along with a custom-built Javascript model to show various nuclear weapons effects. In simpler terms, this means that the NUKEMAP is code that can work with Google Maps technology to show you what happens when a bomb goes off. NUKEMAP2 is essentially the same thing as the original NUKEMAP except the nuclear effects information is based on much more sophisticated coding and models. Information about the models is below.

NUKEMAP3D uses the same models, but uses the Google Earth API to display these in a 3D environment. This allows the visualization of 3D mushroom clouds, for example, by importing cloud models and manipulating them within the browser environment.

All of the coding, design, and adaptation of the old Cold War models to modern Javascript was done by Alex Wellerstein (me). The population density dataset was graciously purchased for this use by the Center for History of Physics at the American Institute of Physics, and AIP in general needs to be credited for supporting the NUKEMAP activity.

coinffeine.png

THE DECENTRALIZED BITCOIN EXCHANGE

Coinffeine is an open source, peer-to-peer (P2P) bitcoin exchange platform. With Coinffeine you are able to buy and sell bitcoins securely and anonymously without having to rely on a centralized exchange. It’s like BitTorrent for your bitcoins!

Coinffeine is the next-gen bitcoin exchange, with a dramatically different approach than traditional exchanges. We exploit the full potential of the bitcoin protocol to give you the most secure, private and reliable platform in the market.

Secure
You are always in control of your bitcoins and your trusted payment processor of choice is in control of your local currency.

Private
The exchange is done peer-to-peer (P2P), so there is only a very limited disclosure of information (your payment processor account so the money can be transferred) with the person you are doing the exchange.

Reliable
Coinffeine is completely distributed, just like BitTorrent, so even if our server is overloaded, gets hacked or explodes it won’t affect the network and the exchange can continue to work without it being affected.

Immediate availability
Unlike traditional exchanges, you receive your bitcoins directly to your wallet and your local currency directly to your payment processor’s account, so you can start spending them as soon as the exchange is finished.

Less fees
Coinffeine is a distributed exchange. This means we have less operational cost which results in less fees. For now, Coinffeine will not charge any fee at all, you only need to pay the standard bitcoin transaction fee plus any fees your payment processor might charge you.

Open Source
Our code is open to inspection, audit and review by anyone to ensure that Coinffeine is trustworthy. We accept bug reports and patches from the community to ensure the highest level of quality.

Features and Philosophy
Unlike traditional online exchanges, Bitsquare is designed to be:
Instantly accessible – no need for registration or approval from a central authority.
Decentralized – there is no single point of failure. The system is peer-to-peer and trading can not be stopped or censored.
Safe – Bitsquare never holds your funds. Decentralized arbitration system and security deposits protect traders.
Private – no one except trading partners exchange personally identifying data. All personal data is stored locally.
Secure – end-to-end encrypted communication routed over Tor.
Open – every aspect of the project is transparent. The code is open source.
Easy – we take usability seriously.
Bitsquare is for those who do not want to forfeit control or privacy to a central authority in order to trade with other individuals. We regard financial transactions as a form of private speech that should be protected from surveillance by banks, governments, and other institutions.
