SSL为安全套接层协议，是用于在Web浏览器和Web服务器之间进行安全信息交换的一种协议。其主要提供了两个核心的安全服务：数据加密和身份验证。作为网络安全的基础协议，SSL在网络数据传输中起到了至关重要的保密和安全保障作用。

Prompting is like web design. Let's call it prompt design, and build better tools for it.

Notifications (e.g. email, push, in-app messages) play an important role in driving user retention. In our previous system, which operated on a daily budget allocation model, the system relied on predicting daily budgets for individual users on a daily basis, constraining the flexibility and responsiveness required for dynamic user engagement and content changes. Notification Event Processor (NEP) is a next generation notification system developed at Pinterest, offering the flexibility to process and make decisions to send notifications in near real-time. By harnessing the power of machine learning, NEP determines various factors for sending notifications, such as content selection, recipient targeting, channel preferences, and optimal timing. The implementation of this system resulted in significant improvements in user email and push engagement metrics and weekly active user (WAU) growth.

什么是原型链，每个对象（Object）都有一个私有属性指向另一个名为原型（prototype）的对象。

ES 进行信息检索的时候，boolean 查询组合条件有 must/must_not/should/filter四个操作。

其中 must 和 filter 的用途都是用于过滤必要符合的条件，但是 filter 在查询过程中不算分并且可以进行缓存，这样逻辑简单又可以加速的查询方式经常得到官方的提倡。

可是，只有 filter 的条件可以被缓存么？这里的缓存是属于哪一部分？

缓存有什么样的进入和淘汰机制？怎么去监控缓存的使用情况？

Generating structured data from unstructured inputs is one of the core use cases for AI in today’s applications. Developers use the OpenAI API to build powerful assistants that have the ability to fetch data and answer questions via function calling(opens in a new window), extract structured data for data entry, and build multi-step agentic workflows that allow LLMs to take actions. Developers have long been working around the limitations of LLMs in this area via open source tooling, prompting, and retrying requests repeatedly to ensure that model outputs match the formats needed to interoperate with their systems. Structured Outputs solves this problem by constraining OpenAI models to match developer-supplied schemas and by training our models to better understand complicated schemas.

一图胜千言，图片是信息传递的重要载体。当用户进行社交媒体分享时，图片是比文字更加直观的展示方式。在一些分享的场景可能天然就有图片，比如分享一个商品，商品的图片就是最直观的展示方式。但是在一些场景下，可能没有天然的图片，比如分享一个从北京到上海的火车线路，这时候就需要我们自己生成图片。
