Google Protocol Buffers + gRPC
This document discusses Google Protocol Buffers (Protobuf), a method for serializing structured data that is faster than JSON or XML. It is well-suited for server-to-server communication where human-readability is not required. Protobuf uses a binary format that allows for higher throughput than technologies like HTTP with JSON. The document also introduces gRPC, which extends Protobuf to provide an RPC framework using Protobuf serialization.
DBXTalk - Smalltalks 2011
The document introduces DBXTalk, an open source relational database solution for Smalltalk. It includes an open database driver (OpenDBX), an ORM called Glorp, scaffolding tools (DBX Magritte), and a GUI browser (DBXBrowser) to interact with the database. The speaker discusses running over 800 unit tests on various databases with success and some errors, and plans for additional documentation chapters. The goal is to enable serious database usage in Smalltalk applications.
The Rise of Functional Programming
The document discusses the rise of functional programming. It provides an example comparing an imperative solution in Java to sum the ages of persons over 20 to a functional solution. The functional solution uses reduction and has no mutable state. Functional programming is described as writing what you want, not how to do it, with everything being a function. Benefits mentioned include stateless programming which aids reasoning, easy distribution and parallelism, and easier program proof. The document also briefly mentions functional languages like Haskell and Erlang, as well as Java's addition of lambda expressions in Java 8 to provide more functional capabilities.
PHP vs Node.js
This presentation takes you through the basic features of PHP and Node.js and the difference between them. It also suggests some of the popular frameworks for each of them.

Testing and Developing gRPC APIs
(1) Attendees are muted and should ask questions under the Q&A section. (2) A recording of the session will be shared after completion. (3) Participants are asked to provide feedback through a survey.
gRPC with java
Munander Maan presented an introduction to gRPC, a modern, fast and efficient open-source framework developed by Google. The presentation covered what gRPC is, how it works internally using Protocol Buffers, its advantages over REST APIs, how it achieves scalability, and different types of APIs that can be built with gRPC. The agenda included deep dives into gRPC internals, comparisons with REST, scalability, and API types.
What is gRPC introduction gRPC Explained
gRPC is an open source high performance RPC framework developed by Google. It uses HTTP/2 for transport, Protocol Buffers as the interface description language, and provides features such as authentication, bidirectional streaming and flow control. gRPC can connect microservices efficiently and is used by many companies including Google, Uber, Square and Netflix. It generates client and server code for multiple languages and can be used for building distributed systems like microservices architectures.
grpc_tutorial.pdf
The document provides an overview of gRPC and how to set up a basic "Hello World" application with gRPC in Java. It describes creating a .proto file to define the service and messages, setting up the gRPC server to handle requests, and generating client code from the .proto file to make requests to the server. The server implementation returns a greeting message in response to the client request.

Introduction to gRPC (Application) Presentation
In gRPC, a client application can directly call a method on a server application on a different machine as if it were a local object, making it easier for you to create distributed applications and services. As in many RPC systems, gRPC is based on the idea of defining a service, specifying the methods that can be called remotely with their parameters and return types. On the server side, the server implements this interface and runs a gRPC server to handle client calls. On the client side, the client has a stub (referred to as just a client in some languages) that provides the same methods as the server.
REST in Peace. Long live gRPC!
Devoxx UK, May, 2022, Mario-Leander Reimer (@LeanderReimer, Principal Software Architect bei QAware).
== Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! ==
This talk focused on modern and efficient Inter Process Communication (IPC) for microservices. We start with a REST API, built using JAX-RS and Quarkus to briefly discuss the pros and cons of this approach. We extended the API with an efficient Protobuf payload representation in order to finally transform the API into a fully fledged high-performance gRPC interface definition. But that’s not all! To put some extra icing on the cake, this talk demonstrated how to consume the gRPC service from a JavaScript web client and also how to completely generate a matching REST API from an enhanced gRPC interface definition to ensure full interoperability in a microservice architecture.
Introduction to gRPC Presentation (Java)
gRPC, which stands for Remote Procedure Call, is an open-source framework developed by Google. It is designed for building efficient and scalable distributed systems. gRPC enables communication between client and server applications by defining a set of services and message types using Protocol Buffers (protobuf) as the interface definition language. gRPC provides a way for applications to call methods on a remote server as if they were local procedures, making it a powerful tool for building distributed and microservices-based architectures.
Introduction to gRPC
gRPC is a remote procedure call framework developed by Google that uses HTTP/2 for transport, Protocol Buffers as the interface definition language, and provides features such as authentication, bidirectional streaming and blocking or nonblocking bindings. It aims to be fast, lightweight, easy to use and supports many languages. Key benefits include low latency using HTTP/2, efficient serialization with Protocol Buffers and multi-language support.

Tecnologia rest em python
This document discusses REST technology and how to implement it in Python. It introduces REST and compares it to SOAP. It then outlines the 6 steps to create a RESTful web service: 1) separate client and server responsibilities, 2) make the server stateless, 3) allow caching, 4) use a layered system with intermediaries, 5) implement a uniform interface using URIs, representations, status codes and headers, and hypermedia, and 6) optionally allow code on demand. The document concludes by mentioning JSONSchema and stating that examples of implementing REST in Python will follow.
Bringing Learnings from Googley Microservices with gRPC - Varun Talwar, Google
Varun Talwar, product manager on Google's gRPC project discusses the fundamentals and specs of gRPC inside of a Google-scale microservices architecture.
Comparison between-rpc-rmi-and-webservices-son-1228374226080667-8
The document compares and contrasts three technologies for remote procedure calls: RPC, RMI, and web services. RPC was introduced in 1976 and provides a simple way to call remote procedures but has disadvantages like complexity and lack of features. RMI was introduced as part of Java to address some of RPC's issues, providing object orientation and features like load balancing. Web services emerged in the early 2000s and use HTTP and XML-based standards like SOAP, WSDL, and UDDI, providing universal support, low costs, and allowing services to easily expose capabilities to others.
Rpc, Rmi And Webservices 2
The document compares and contrasts three technologies for remote procedure calls: RPC, RMI, and web services. RPC was introduced in 1976 and provides a simple way to call remote procedures but has disadvantages like complexity and lack of features. RMI was developed later for Java and improved on RPC with object orientation and features like load balancing. Web services emerged in the early 2000s and use open standards like HTTP, XML, and SOAP to enable universal interoperability across platforms and languages.

Up and Running with gRPC & Cloud Career [GDG-Cloud-Dhaka-IO/2022}
The document discusses gRPC and cloud computing. It provides an overview of gRPC including that it is an open source RPC framework created by Google. It compares gRPC to REST and describes how gRPC uses HTTP/2 and protocol buffers. The document also discusses cloud computing concepts like IaaS, PaaS, SaaS and common cloud jobs. It lists skills needed for cloud engineering and certifications from Google Cloud.
gRPC or Rest, why not both?
The document discusses REST and gRPC APIs. It describes REST as a design pattern that uses HTTP and represents resources with JSON or XML. While REST is widely used, it has disadvantages like bloated data payloads and lack of a formal contract. gRPC is introduced as an alternative that is high performance, uses protocol buffers for compact payloads, and has generated client/server code in many languages. The document also describes how grpc-gateway can be used to expose existing gRPC services through a RESTful JSON API via HTTP to support existing clients.
gRPC, GraphQL, REST - Which API Tech to use - API Conference Berlin oct 20
The document discusses different API technologies including gRPC, GraphQL, and REST. It provides overviews of each technology, describing their origins, key concepts, pros, and cons. gRPC was developed by Google and uses protocol buffers for messages and HTTP/2 for transport. GraphQL was created by Facebook and uses a query language for clients to specify the exact data they need. REST is the more established standard based on HTTP and uses URIs for identification of resources.

Build, deploy and scale: Django, GraphQL and SPA (DjangoCon EU 2021)
After building, deploying and scaling a dozen on products with the Django + GraphQL + SPA (React) setup, we have come to understand what works and what does not. In this talk, I will share our findings on how to do the same.
I will be using a simplified StackOverflow clone for demonstration. First, I will introduce Python-Graphene (and few other related libraries), the library that is used to build GraphQL endpoints. Then the talk will focus on how to structure your Django GraphQL project. Share the toolchain (a few management command scripts) that are handy to export your constants & GraphQL schemas to be used with your SPA. Integrating with an SPA (React for demo purpose) Auth, API calls.
Then I will talk about how you go about deploying your API using 2 different strategies:
1. Docker compose / swarm (Vendor independent, non-production workloads)
2. AWS Fargate (Vendor dependant, production workloads, serverless containers)
And a cost-effective and highly scale-able deployment strategy for your SPA (using AWS S3, CloudFront and ACM).

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Garuda: Automagically Exposing Djagno ORM over gRPC for microservices written in any other languages
- 1. Garuda Automagically Exposing Django ORM over gRPC for microservices wri en in any other languages @dhilipsiva
- 2. A bit about myself Optimistic Nihilist. Wannabe Astrophysicist. I code for fun & pro t. I love Science, Python, FOSS & tness. Dad of 2. Environmentalist. Story Teller. Gamer. http://dhilipsiva.com dhilipsiva@gmail.com
- 3. I have no idea what I am talking about
- 4. Microservices I am assuming that everyone has a basic understanding of a microservice architecture For the uninitiated, it is an architectural style that structures an application as a collection of loosely coupled services, which implement business capabilities. The microservice architecture enables the continuous delivery/deployment of large, complex applications. It also enables an organization to evolve its technology stack.
- 5. Implementa on of microservices that I have come across I am just talking about small & medium startups [The only space that I have experience with] CLI, HTTP, RPC, Thrift
- 6. CLI Call a command line/console application with Popen or something similar Very notorious (because we have limited control over the called program) Scaling is a bit tricky
- 7. HTTP Build a REST / SOAP endpoint Document the message exchange format (which is a manual process and might be error prone) relatively easier to scale compared to CLI method
- 8. RPC & Thir Build RPC Server and clients Just as easy to scale as HTTP method, but this is faster because of strongly typed messages serialize and deserialize very fast and data is smaller compared to JSON / XML Relatively harder (Implementation wise) because of all the learning curve involved We have well-de ned Data schemas; So manual intervention is not required to communicate changes
- 9. Garuda How to make the RPC Implementation relatively easier Introducing Garuda Automagically Exposing Django ORM over gRPC for microservices written in any other languages It's done with the help of gRPC (for now). So you need to understand Protobuf, gRPC and the likes.
- 10. RPC Frameworks gRPC: A high performance, open-source universal RPC framework Cap'n Proto: Cap'n Proto is an insanely fast data interchange format and capability-based RPC system.
- 11. Protobuf (Which we use with gRPC) Protocol Buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. message Article { string id = 1; string content = 2; int32 status = 3; string title = 4; }
- 12. gRPC Service De nition service Blog { rpc CreateArticle (Article) returns (Article) {} rpc UpdateArticle (Article) returns (Article) {} }
