1. Quick Intro to Node.js
2. What it is ? - based on Javascript V8 runtime - event driven - non-blocking standard libraries - Streams is supported in most APIs - support for C/C++ extension - package manager is included
3. Blocking code Non-blocking code ေမာင္လွ  တံျမက္စည္းလွည္း၊  ေရခ်ိဳး  ၿပီးရင္  ထမင္းစားထားေခ်။ ေမာင္ျမသည္  ေဆးေပါ့လိပ္ကုုိ  ပါးေစာင္တြင္ခဲကာ  ဖဲထုုိင္႐ုုိက္ေနသည္။  
4. Real World Example var contents = fs.readFileSync('/etc/hosts'); console.log(contents); console.log('Doing something else'); ! fs.readFile('/etc/hosts', function(err, contents) { console.log(contents); }); console.log('Doing something else’);
5. Differences ! - non-block code - single thread yet multiple pipeline - event driven - realtime ready Same - npm ( gem,composer,pip ) - modular structure - frameworks (express,sail,meteor,koa)
6. - Javascript everywhere - can freely decide project structure - same with front-end code - reusable - familiar to us - can happily work with JSON style databases (MariaDB,MongoDB) Why ?? (Hooray!, rise of Javascript)
7. Who use it ??? - LinkedIn,Yahoo! Microsoft Azure, Paypal - Strong and active community (Google) - Joyent start it, visionmedia contribute a lot and strongloop - approximately repo rate 4x increase in this year - There’s local node.js group (small but yet promising)
8. How ??
9. What node isn’t - Frameworks like Laravel, Django and Rails - New Programming Language - Silver Bullet - Multi-threaded - For Beginners What node is - Web Socket Server - Fast File upload Client - Ad Server - Any Realtime data app
10. Pitfall - Memory Management - hard to catch on - no significant difference or even slower in normal traffic - difficult to debug - strongly relies on benchmarking - not suit with normal crud applications - need to embrace whole new paradigm
11. The next Web Imagine
12. Furthermore Learning sites (Codeschool,tutplus, and many so on) Node.js offical website Google Node.js videos on youtube ! !
