COSCon 2019 动手训练营

Workshop 这种活动形式，国内的小伙伴们可能了解不多。它直译过来通常叫工作坊，意译又称作动手训练营，是一种重在现场实操的技术活动。它与我们学生时代的“上机实验课”很像，但需要参与者带着自己的电脑，通过现场提供的多元化技术平台（如开源社自研的开放黑客松平台），亲身体验各类新技术，快速上手~

Node.js Code+Learn Workshop

本次工作坊将教大家如何给 Node.js 社区提交代码，贡献 Node.js 仓库。并尽量能给每个人分配实战小练习，让大家都能体验一次给 Node.js 提交代码。

Hands-on Pinpoint Plugin Workshop: How to trace your system down to the code level

Pinpoint is currently one of the most popular open-source APMs in China, capable of distributed tracing with code-level visibility.

• This interactive workshop kicks off with an introduction to how distributed tracing works in general, and how Pinpoint works internally to trace your applications over multiple nodes all the way down to the code level.
• We will build a brand new plugin together from scratch, discussing various issues such as deciding tracepoints and class load time/runtime considerations, so that everyone will gain the first-hand experience in making a Pinpoint plugin.
• Armed with this knowledge, you will be able to build a plugin for any library so that you can trace your very own system, or simply throw a pull request and join in on an open-source community.

受众收获

All those who were curious about how java agents work, as well as those interested in the application performance monitoring (APM) tool, will find the workshop interesting. The workshop covers a wide range of topics - from bytecode instrumentation to distributed tracing, and the audience will be able to gain first-hand experience into seeing how the different topics come together to run an APM tool.
