# AWS LAMBDA tutorialspoint SIMPLY EASY LEARNING www.tutorialspoint.com https://twitter.com/tutorialspoint ## About the Tutorial AWS Lambda is a service which computes the code without any server. basics of AWS Lambda and its programming concepts in simple and easy way. This tutorial will give you enough understanding on various functionalities of AWS Services to be used with AWS Lambda with illustrative illustrative examples. ## Prerequisites To work with AWS Lambda, you need a login in AWS. The details on how to get free login is discussed in tutorial. AWS Lambda supports languages like NodeJS, Java, Python, C#

## SOFA MESH 的通用协议扩展 邵俊雄（熊啸） 2018.08.25 ## AGENDA • SOFA MESH 介绍 • SERVICE MESH 落地的问题 • SOFA MESH 的通用落地方案 • DNS 服务寻址方案 • X-PROTOCOL 通用协议 · 问答 ## SOFA MESH • 从 ISTIO 克隆并保持同步更新 - 使用 SOFA-MOSN 代替 DUBBO 协议支持 ## SOFA MESH 的统一解决方案 • 采用 Kubernetes Native 方式落地微服务应用 • 使用 INTERFACE 作为 DNS 来寻址服务 • 开发一个通用协议处理框架 - 避免为不同的微服务框架修改 PILOT 代码 • 通过插件的方式按需支持新的协议 • 对应用代码无侵入性 • 为微服务框架提供轻量化客户端 ## 落地一个微服务框架需要的工作 Service RPC Service 关联到一个 Kubernetes 服务 RPC Service 的域名就是其接口 ## X -PROTOCOL 通用协议扩展 ## 目标 • Kubernetes Native，高性能，低侵入性的通用 Mesh 落地方案 • 支持新 RPC 框架和通信协议低成本接入 • 协议扩展对 Mesh 控制平面透明化 • 允许对协议多层次，插件化的扩展

@新媒沈阳 团队：余梦珑博士后 • Deepseek是什么？ • Deepseek能够做什么？ · 如何使用Deepseek? ## DeepSeek是什么？ - DeepSeek是一家专注通用人工智能（AGI）的中国科技公司，主攻大模型研发与应用。 • DeepSeek-R1是其开源的推理模型，擅长处理复杂任务且可免费商用。 性能对齐 OpenAI-o1 正式版 DeepSeek-R1 任务。 |维度|推理模型|通用模型| |---|---|---| |优势领域|数学推导、逻辑分析、代码生成、复杂问题拆解|文本生成、创意写作、多轮对话、开放性问答| |劣势领域|发散性任务（如诗歌创作）|需要严格逻辑链的任务（如数学证明）| |性能本质|专精于逻辑密度高的任务|擅长多样性高的任务| |强弱判断|并非全面更强，仅在其训练目标领域显著优于通用模型|通用场景更灵活，但专项任务需依赖提示语补偿能力| ## 通用模型 - 需显式引导推理步骤（如通过CoT提示），否则可能跳过关键逻辑。 • 依赖提示语补偿能力短板（如要求分步思考、提供示例）。 ## 关键原则 ## 模型选择 1 优先根据任务类型而非模型热度选择（如数学任务选推理模型，创意任务选通用模型）。 ## 提示语设计 2 - 推理模型：简洁指令，聚焦目标，信任其内化能力。（“要什么直接说”）。 - 通用模型：结构化、补偿性引导（“缺什么补什么”）。

and a generic lambda $ \Lambda $ , it would return the result of the lambda applied to the i-th element of the tuple: $ \Lambda(\mathcal{T}_i) $ ? ## The trivial approach 1 i == 0 ? lambda(std::get<0>(tuple)): 1 ? lambda(std::get<1>(tuple)): 3 i == 2 ? lambda(std::get<2>(tuple)): 4 i == 3 ? lambda(std::get<3>(tuple)): 5 // ... 6 lambda(std::getlambda(std::get<0>(tuple)) + 2 (i == 1) * lambda(std::get<1>(tuple)) + 3 (i == 2) * lambda(std::get<2>(tuple)) + 4 (i == 3) * lambda(std::get<3>(tuple))

the project ## Lambda functions - Lambda functions are flexible and powerful tool • With noisy syntax • And this is yet another footgun Use less: • Nested lambda functions • Long lambda functions - - Lambda functions assigned to local variables ## Use less lambda functions core::Expected◁ WindowLayoutStack::add( const window::Uri& windowUri) { return loadWindow( windowUri, m_windowLoader) function • ...used in many places • …and you cannot easily change a signature - A solution with lambda functions looks too cumbersome • std::bind_front – C++20 • std::bind_back-C++23 ## bind back/front
