This document provides an overview of big data. It defines big data as large volumes of diverse data that are growing rapidly and require new techniques to capture, store, distribute, manage, and analyze. The key characteristics of big data are volume, velocity, and variety. Common sources of big data include sensors, mobile devices, social media, and business transactions. Tools like Hadoop and MapReduce are used to store and process big data across distributed systems. Applications of big data include smarter healthcare, traffic control, and personalized marketing. The future of big data is promising with the market expected to grow substantially in the coming years.

Order-food system for everyone.
簡單說是一個訂便當系統,但這並不特別,
我們還加上了與 Slack API 以及使用Hubot來讓一些繁瑣的事情自動化。
雖然不像Din Ben Don以及市面上功能那麼完善(複雜),
不過正因為這樣,預留了很多可以客製化的空間,
環境架設及安裝也相當簡易。
(server部分是用Heroku,如果你有自己管理主機的經驗,會變得更加簡單)
總之就是一個簡單的 Chatops 基礎實作
The document discusses using the SPEA2 algorithm for multi-objective optimization to find non-dominated classification rules from transaction data. It describes classification rule mining, objectives of accuracy, comprehensibility and interestingness, and the SPEA2 approach which uses selection, crossover and mutation operators over generations to find a non-dominated solution set. A case study applies SPEA2 on insurance broker transaction data to extract non-dominated rules relating customer attributes to insurance products.
HTTPS: What, Why and How (SmashingConf Freiburg, Sep 2015)Guy Podjarny
When users use our sites, they put their faith in us. They trust we will keep their information from reaching others, believe we provided the information they see, and allow us to run (web) code on their devices. Using HTTPS to secure our conversations is a key part of maintaining this trust.
If that’s not motivation enough, the web’s giants are actively promoting HTTPS, requiring it for features such as HTTP2 & ServiceWorker, using it for search engine ranking and more. To make the most of the web, you need to use HTTPS.
This deck reviews what HTTPS is, discusses why you should prioritize using it, and cover some of the easiest (and most cost effective) steps to get started using HTTPS
This presentation, by big data guru Bernard Marr, outlines in simple terms what Big Data is and how it is used today. It covers the 5 V's of Big Data as well as a number of high value use cases.

This is how we build www.attictv.com with NodeJS, and the development philosophies we adopted as a startup.
AtticTV is a music video website that is going to the the MTV of the Internet. Just get on www.attictv.com and music video starts playing, no searching, no waiting.
The slide notes are in Chinese because I presented the slide at NodeJS Party Taiwan at Taipei. If you have any questions, feel free to buzz me at @conancat on Twitter!
