It shows how these capabilities help engineering teams detect issues proactively, understand their scope and root causes, correlate frontend signals with backend traces, and resolve production problems faster. ### Source excerpt When something breaks in production, the questions that matter most are also the toughest to answer from metrics alone: who was affected, what did they actually see, and is this worth waking someone up for? Answering those questions requires a fuller picture of the issue and its impact on your users. That's where Digital Experience Monitoring (DEM) in Grafana Cloud comes in. By combining Frontend Observability and Synthetic Monitoring, DEM connects real user experiences with proactive testing, helping engineering teams understand the scope of an issue, investigate its cause, and resolve it faster, all within Grafana Cloud. In this blog post, we'll walk through some of the latest DEM updates in Grafana Cloud, and how to get started. You can also learn more by watching the video below. First, what is Digital Experience Monitoring? Digital Experience Monitoring in Grafana Cloud gives you a complete picture of how users experience your web applications, from real user data to proactive synthetic checks. DEM helps your team achieve: Real user visibility: know how users truly experience your web application, not just what your backend metrics suggest. Proactive detection: catch problems before your users do, using automated checks against your critical user journeys. End-to-end correlation: connect a frontend signal to the backend trace behind it. Faster resolution: cut your mean time to recovery from hours to minutes. Session Replay: see exactly what your users saw Session Replay in Grafana Cloud Frontend Observability lets you visually replay what a user saw and did inside your web application. Your team can watch exactly what users experienced and correlate it with real user monitoring signals like Core Web Vitals, user actions, and traces, which makes it a powerful tool for investigating bugs and running root cause analysis. Session Replay is powered by Faro, Grafana's open source JavaScript instrumentation library for collecting real user monitoring data.

It describes the course's 17 chapters, practical API-learning exercises, coverage of REST APIs, OpenAPI, Swagger UI, testing and publishing API documentation, and a PDF edition exceeding 900 pages. ### Source excerpt While researching information for my job about the Swagger UI and how it can be used for testing, I came across this free course, called Documenting APIs: A guide for technical writers and engineers at https://idratherbewriting.com/learnapidoc/docapis_overview.html written by Tom Johnson, a technical writer based in Seattle who works for Google. The course looks intense, containing 17 chapters talking about Introduction to REST APIs, using APIs like a developer, Documenting API endpoints, the Open API spec, Testing API docs, Publishing API docs, and more. From the Course Introduction: "You'll first learn about API documentation by using a simple weather API to put a weather forecast on your site. [...] As you use the API, you'll learn about endpoints, parameters, data types, authentication, curl, JSON, the command line, Chrome's Developer Console, JavaScript, and more. The idea is that rather than learning about these concepts independent of any context, you learn them by immersing yourself in a real scenario while using an API. Immersion in real scenarios makes these tools and technologies more meaningful. "We'll then transition into standards, tools, and specifications for REST APIs. You'll learn about the required sections in API documentation, analyze examples of REST API documentation from various companies, learn how to join an open-source project to get experience, and more. "[...] We'll also dive into specifications such as the OpenAPI specification and Swagger UI (which provides tooling for the OpenAPI specification). Additionally, you'll learn how to document native library APIs and generate Javadoc". Tom Johnson offers a PDF version of this free course... over 900 pages, with more always being added. It also offers many workshop-like activities you could put in an actual itinerary. You would need for the course: Chrome, since it provides "a Javascript Console that works well for inspecting JSON", the JSON Formatter Chrome extension, Postman, a GitHub acco ## OpenTrailPaper transforms LILYGO T5 E-Paper S3 Pro devkit into a DIY e-paper bike computer DevFeed: [OpenTrailPaper transforms LILYGO T5 E-Paper S3 Pro devkit into a DIY e-paper bike computer]() Original publisher: [Read original article]() Author: Jean-Luc Aufranc (CNXSoft) Published: 2026-09-05T08:01:22Z Content type: news Language: en Sources: [CNX Software - Embedded Systems News]() Topics: [Embedded Systems](), [ESP32-S3](), [Open Source](), [Android](), [iOS](), [Bluetooth](), [ESP-IDF](), [GitHub](), [JavaScript](), [Python](), [web browser]() Tags: [android](), [bluetooth](), [browser](), [core](), [display](), [diy](), [e-ink](), [e-paper](), [epaper](), [esp-idf](), [esp32](), [esp32-s3](), [espressif](), [firmware](), [github](), [gps](), [hardware](), [ios](), [javascript](), [lilygo](), [lora](), [open-source](), [python]() ### AI overview OpenTrailPaper is an open-source DIY e-paper bike computer project for the LILYGO T5 E-Paper S3 Pro, using ESP32-S3 firmware alongside Android and iOS companion apps.
