API Rate Limiter

http://bitbucket.org/chomnoue/api-rate-limiter/src/master/
To avoid performance issues and reduce costs, API速率限制器允许公司避免对给定API进行过多调用.

The limits are configurable, 速率限制器应该在以下情况下限制AIP调用:
1. 同一时间窗口内来自客户端的请求太多
2. 每个月来自特定客户的请求太多
3. Too many requests across the entire system

该应用程序是为在分布式环境中运行而构建的，并且经过了有效扩展的设计.

NPS Score from Social Media

一个无服务器API，可以收集标记目标公司的推特帖子, runs a sentimental analysis on them, and computes their NPS (see Medallia.com/net-promoter-score/#). It runs on AWS, involving cloud services like Lambda, Firehose, S3, DynamoDB, Comprehend, and the NPS score for telcos (Social-nps.herokuapp.com/dashboard). On top of that, 我用Python和Bokeh库构建了一个仪表板，并将其部署在Heroku上，以显示计算出的NPS分数.

Ebola Data Visualization

http://chomnoue.github.io/EbolaDataVisualizationND/
这张可视化图显示了2014年8月至2015年5月西非埃博拉病例的演变情况, as reported by the WHO.

用户可以选择一个指标和一个日期在地图上查看状态. 他还可以选择为所选的指示器重放动画.

我选择在地图上用橙色来区分受影响的国家. 只有受影响的国家的名字，让用户专注于他们.

红色圆圈表示每个国家的指标值. 我选择了一个对数尺度的圆半径，所以只有少数情况下, countries' values can be seen on the map.
