    In this talk, Shubhra Kar - StrongLoop Director of Products and Node.js trainer/evangelist, will dive into three essential areas you should be looking at to identify performance tuning opportunities in your Node apps. First, we'll look at how and why to perform CPU and Heap profiling. Second, how to troubleshoot memory leaks and understand the difference between rapid and slow leaks. Finally, we'll do a deep dive into how V8's garbage collection works and the role it plays in optimizing Node apps.

                      With all the news of malicious "hacking" in the news lately, let's get some hacking for good here. What is a hackathon? From Berkeley to MIT and now to China, the "hackathon" movement is one that presses on ideas and skillset, endorsing creative chaos and the ambitious spirit of "why not?". If you are averse to procrastination, it will push the envelope and challenge you to burst into a burning of adrenaline and fumes alike. HackShanghai is a hackathon in Shanghai (run by a group of students at New York University Shanghai) where teams work tirelessly together to build and pitch a prototype of a product within 36 hours using coding, hardware, design, planning, and imagination. From the apps on your phone to the infrastructure of healthcare to clean water, these technological push-forwards are ubiquitous in the world today. This is the do-good side of "hacking", with the same knowhow but a different purpose. Try a day without technology and the spirit of new ideas suddenly becomes realized. Whether for experience, learning, growth, curiosity, or just plain old fun, hackathons across the world are a great place for any tinkerer of bricolage. In 2013-2014's first small HackSH, a group of NYU Shanghai freshmen with a propensity for alcoholic beverages created with an Arduino-wielding product to promote recycling. Now in HackShanghai 2014-2015, teams from colleges all over the world executed ideas such as educational motion-sensing cooking programs, DUI-prevention protocols, and integrative multimedia web apps for collaboration. Following within the eastern board, Beijing's Tsinghua Hacks and Korea's government-sponsored Global Hackathon Seoul are also new members to the hackathon family working together to change the world (or at the least make it a bit more fun). Who knows what will happen in 2015?
