Experience
Heavy Reading Barbell and Book Club
http://www.heavyreadingclub.com/这是一个搞笑的WordPress博客，里面的帖子都是由健身爱好者撰写的人工智能生成的. 这些帖子混合了书评和健身建议，这些建议是在知道会被忽视的情况下给出的.
The business logic is written in Java and executed in AWS. There is a periodic SQS trigger that invokes a lambda function. 该函数选择一个随机提示并查询OpenAI API以生成书评. The lambda parses the response from OpenAI, packages it into a WordPress post, 然后使用WordPress REST API将该帖子发布到指定的WordPress实例.

TSDBot: A Java-based Discord Chat Bot
http://github.com/schoolyd/tsdbot2This project is a chatbot for Discord written in Java. It has several features:
1. Easily-extensible array of "functions" ranging from trivial (e.g.(替换前一条消息中的一些文本并返回结果)到更复杂的(例如.g., 从聊天记录中随机挑选一行，并将其发送给电子游戏开发商Bungie的社区经理)。
2. Integration with AWS, specifically S3 and EC2
3. Via Dropwizard, implements an embedded Jetty server for serving HTTP requests, including a navigable website
4. Implements streaming, 整合了Discord聊天和托管网站的广播媒体服务. This service is modeled on a "job polling" framework, 流媒体与独立的“代理”可执行JAR一起存储在不同的机器上. 这个代理会定期向Discord机器人发送心跳信号，告知它有哪些视频可用. The Discord bot can display this video catalog to users. If a user wants to play any video, the Discord bot will place a "job" in its queue for the specific agent, and the next time the agent sends a heartbeat, 它将收到“播放此视频”作业，并将开始流式传输视频

TSDTV.java
http://github.com/schoolyd/tsdbot2这段代码表示广播视频服务的“控制器”类，该服务集成了我编写和维护的Discord聊天机器人. 它允许异步播放由用户选择的流媒体.
