IEEE had 400 engineer volunteers available when the project launched, and hopes to recruit more.

Azure Mobile Services lets you build and host the backend of any mobile app. New Relic Mobile allows users to monitor the end-to-end performance of all their mobile apps in real-time, using real-user data. So it only makes sense that we would team up with our partner Microsoft for an iOS and Android Hackathon!

To make it possible, we leveled up the Wrapper API to make it more extensible and to allow developers to directly configure it instead of relying on global state. After such improvements, it was very easy to change the Simple Form configuration to work with Bootstrap 3. I'll talk more about this in a future post.

Integrating Bootstrap with Simple Form should be as easy as it was before. We are working on the documentation before the final release but you can find examples about how …

Towards the end of last year, we started work on a European collaborative project called DaPaaS ( Data-and-Platform-as-a-Service). It aims to optimise and simplify both publication and use of Open Data across different platforms.

Being part of this is great for us because it's very well aligned to our development objectives for our PublishMyData platform .

Our main role in the project is to simplify data publishing for non experts. So, we'll be developing tools …

Or like Rey Faustino , who I wrote about last month. He grew up in a working-class family in Southern California that relied on social services to make ends meet. Now he's working on fixing the problems he remembered as a child through One Degree, which is a Yelp-like platform that helps Bay Area families find the right non-profits and social services for them. It's supported by Y Combinator and has thousands of users.

Many of the people who come here …

Here is the rough list of iterations we worked through in developing this tool/process:

Standard pt-heartbeat update/monitor

Asynchronous, threaded update/monitor tool

Synchronized (via zeroMQ), threaded version of the tool
