Build resource server & client for OCF Cloud (2018.8.30)

This document discusses Netflix's API ecosystem built using Scala, Scalatra, and Swagger. It summarizes Netflix's use of these technologies to build APIs that power their consumer electronics partner portal and enable certification of Netflix ready devices. It describes how the APIs provide a single source of truth for all device data at Netflix and correlate streaming quality metrics. It then discusses aspects of the architecture including the manager layer containing business logic, HTTP layer for handling requests/responses, and use of Scala, Scalatra, Swagger, and deployment process including immutable infrastructure.

Our daily work is comprised of testing a product and improve its quality. However, here and there, we can come to a state where we find a need to build a tool, that can make our work easierbetter. I will share from my experience when I found myself in a situation where building a tool was needed. We will start with a web application that allows you to know when a food delivery you ordered arrives to the office, and then we will focus on a tool that test the performance of an app from the UI side. We will do a live demo for both of them.

DTrace is a comprehensive dynamic tracing framework created by Sun Microsystems for troubleshooting kernel and application problems on production systems in real time. It provides probes in the operating system and applications to monitor events, collects and aggregates data, and provides tools to analyze the data. DTrace can be used on Unix-like systems like Solaris, Linux, macOS, and in Node.js applications through a DTrace provider. It allows gathering insights about the system and application behavior without restarting or slowing the system.

This document provides examples and documentation on Azure Durable Functions patterns and concepts. It includes examples of orchestrator and activity functions, orchestration triggers, and common patterns like function chaining, fan-out/fan-in, and asynchronous HTTP responses. It also covers durable function concepts such as the control queue, work item queue, and history table.

The document provides an overview of a NodeJS CRUD and deployment course. The course outline includes: setting up a NodeJS environment on SmartOS with MySQL and Git in 3 minutes; tools for cloud development like SSH, SCP, and Git; building a simple web server with authorization using Passport and CRUD functionality with MySQL; and advanced topics like load balancing for cloud services. The course also provides a Micloud server for hands-on labs and sample projects.

The document discusses the process and code for building a client socket application in Java. It covers establishing a connection to a server, obtaining socket information, sending and receiving data, and closing the connection. An example client code is provided that connects to a sample server, receives data as bytes, and prints the response. The client creates a socket, gets input/output streams, reads server data into a byte array, and closes the connection when finished.

This document contains code for a file sharing application that allows users to upload files to Amazon S3 storage and send download links to recipients via email. It includes code for connecting to MongoDB and S3 databases, handling file uploads with Multer, generating signed URLs with AWS, sending emails with Nodemailer, and building APIs with Express. The React code handles form inputs, file previews, and confirming upload status.

Dpilot is a cloud based file transfer application that allows its user to upload data on cloud server and the receiver on the other hand can downlaod the data from the server. The Downlaod information is send to the receiver via mail service. Other Features include:- Secure Login system Easy data Access Lightening Fast Uploads and Downloads Connect with your Facebook Or Gmail Account for easy access

This document provides a tutorial on using ZooKeeper to implement basic distributed synchronization primitives like barriers and producer-consumer queues. It includes code examples for Barrier and Queue classes that extend a base SyncPrimitive class. The Barrier class allows processes to synchronize barrier entry and exit. The Queue class implements a distributed queue where producers can add elements and consumers can remove the oldest element. Both use ZooKeeper to coordinate access through ephemeral nodes and watches.

In SPIRE, attestation is the essential process because it certifies a node or workload, i.e. it asserts the identities of them. This talk describes how SPIRE implement this process and make it flexible. Moreover, it explains the detail of how spire-server and spire-agent (running at a node) interacts in the attestation process.

Secure remote access to the built-in web server of a device is one of the fundamental building blocks for the Internet of Things. my-devices.net enables easy and secure remote access, even if the device is located behind a NAT router or a firewall and does not have a public IP address.

This document discusses dependency injection and inversion of control patterns. It explains that dependency injection frameworks like Angular and Ember use an inversion of control container to manage dependencies and instantiate classes with their dependencies already satisfied. The container owns and manages all class registrations and dependencies. When a class is looked up from the container, it is instantiated with all its dependencies injected. This decouples classes from their concrete dependencies and makes applications more modular and testable.

Hack an ASP .NET website? Hard, but possible! Presentation by Vladimir Kochetkov at Positive Hack Days

1) SCORE is a smart contract platform on ICON that allows developers to write, deploy and interact with smart contracts using Python. 2) T-Bears is a SCORE development suite that provides tools to develop, test, deploy and interact with SCORE contracts. It includes a CLI, sample templates and supports local emulation of contract execution. 3) SCORE contracts are deployed to and run on the ICON blockchain. They can store data on-chain, be invoked by transactions to update state, and trigger events.

FIWARE IoT Hackathon at Campus Party Brazil 2015. Slides for Ultralight2.0 (virtual) devices. Carlos Ralli Ucendo

Every wondered how to make your code physically interact with things in the real world? Got a home automation project in mind? In this presentation we will cover: o) How to get started with Raspberry Pi and C# o) The numerous sensors and actuators you can control o) How to navigate basic electronics o) Different interfaces and how to program them o) Demonstrations of devices at work o) Azure IoT Hub to control your code from the cloud and receive live inputs from your device in a Blazor application

The document provides instructions for setting up a TI-RTOS project for the CC1352R wireless microcontroller. It describes creating a CCS project targeting the CC1352R, configuring compiler and linker settings, generating a system configuration file, and adding TI-RTOS and driver library files. The goal is to build a basic "hello world" project to demonstrate real-time operating system functionality on the CC1352R wireless microcontroller.

This document summarizes an advanced Sigfox workshop covering topics like downlink callbacks, event monitoring, geolocation callbacks, and using AT commands with the Xkit shield. It provides useful resources and contact information for Aurelien Lequertier and Nicolas Lesconnec. The workshop includes demonstrations of configuring downlink callbacks, monitoring for breaks in message sequences, geolocation callbacks, using IFTTT for advanced callbacks, and sending AT commands to the Xkit shield.

Our application and our infrastructure speak, time series are one of their languages, during this talk I will share my experience about InfluxDB and time series to monitor and know the status of our cloud infrastructure. We will show best practice and tricks to grab information from an application in order to understand the mains difference between logs and time series.
