data: Fixing the World, Bang-for-the-Buck

Freakonomics » Fixing the World, Bang-for-the-Buck Edition: A New Freakonomics Radio Podcast:
"Here’s $2.5 trillion. You have 15 years to spend it. How do you distribute this money in a way that will achieve the most good for the world?"

From transcript:
"Just to give you one example, you can probably save one person from dying from malaria for about $1,000. You can probably save one person from dying from HIV/AIDs for about $10,000. Now, both are good deals, but you have to ask yourself, ‘Don’t we want to first save 10 people from malaria before you save one person from HIV?’"

"Copenhagen Consensus Center, which tries to calculate the best return on investment (ROI) for each dollar spent on development aid."

AngularJS courses @ Pluralsight

AngularJS Line of Business Applications – Pluralsight Training
by Deborah Kurata
"This course takes you step by step through the process of building line of business Web applications using Angular. It covers layout and routing, accessing data, building and validating forms, defining business logic, and data visualization."

Based on response of many Pluralsight members, AngularJS is THE most important technology for more than a year now...

tool: "Atom" web editor by GitHub

"At GitHub, we're building the text editor we've always wanted. A tool you can customize to do anything, but also use productively on the first day without ever touching a config file. Atom is modern, approachable, and hackable to the core. We can't wait to see what you build with it.

Atom is a desktop application based on web technologies. Like other desktop apps, it has its own icon in the dock, native menus and dialogs, and full access to the file system.

Open the dev tools, however, and Atom's web-based core shines through. Whether you're tweaking the look of Atom's interface with CSS or adding major features with HTML and JavaScript, it's never been easier to take control of your editor.

$1 billion patents licensing: Samsung (Android)=>Microsoft

Microsoft earned $1 billion from Samsung Android patent licensing last year | The Verge:

"Microsoft has a vast number of Android patent licensing agreements with device makers worldwide, but a Samsung court case has put a figure on exactly how much money the software giant makes from Android. Samsung paid Microsoft $1 billion in patent-licensing royalties last year, a huge sum that has the pair locked in a legal battle over contracts. Samsung originally signed its patent deal with Microsoft in 2011, ahead of its impressive dominance of Android shipments..."

ML: Nvidia GPU "cuDNN" Deep Neural Network Library

Accelerate Machine Learning with the cuDNN Deep Neural Network Library | Parallel Forall
Figure 1: :  Schematic representation of a deep neural network, showing how more complex features are captured in deeper layers.
"...The hottest area in Machine Learning (ML) today however, is the area of Deep Neural Networks (DNNs). The success of DNNs has been greatly accelerated by using GPUs, which have become the platform of choice for training large, complex DNN-based ML systems.
A few that have publicly acknowledged using GPUs with deep learning include Adobe, Baidu, Nuance, and Yandex.

Because of the increasing importance of DNNs in both industry and academia and the key role of GPUs, NVIDIA is introducing a library of primitives for deep neural networks call
ed cuDNN. The cuDNN library makes it easy to obtain state-of-the-art performance with DNNs, and provides other important benefits."

Internet-Connecting Drones (Facebook, Google)

Facebook Lays Out Its Roadmap for Creating Internet-Connected Drones | WIRED:

"Facebook formed its Connectivity Lab earlier this year. Dovetailing with CEO Mark Zuckerberg’s new venture,, its goal is to build and launch a fleet of solar-powered drones that can connect the billions of people currently living off the grid to the internet.1 It arrived just a month before Google agreed to acquire Titan Aerospace, a startup that makes its own solar-powered drones"
