Step-by-Step Guide: Building Your First ASP.NET Controller

·6 views

A new tutorial on DEV Community walks beginners through creating their first ASP.NET controller using C# and .NET 10 or later. The guide covers setting up a controller class, applying routing and API attributes, and migrating endpoints from the main program file. It also demonstrates how to register controllers in Program.cs and test them via the Scalar API reference tool. Additional examples show how to build parameterized endpoints that simulate async delays and return dynamic responses. The series is set to continue with topics covering database integration and more advanced features.

Developer Builds 80 Free Browser-Based Tools After Finding Most Rivals Upload Your Data

A developer discovered that eight out of the first twelve free online developer tools tested were silently sending user data to remote servers, including sensitive items like JWT tokens and config files. Many tools operated this way not out of malicious intent but simply because their logic was built server-side by default. Beyond privacy risks, server-dependent tools introduce latency, rate limits, downtime, and offline unavailability. In response, the developer built over 80 browser-based utilities — including a JWT debugger, JSON formatter, regex tester, and hash generators — that run entirely client-side using vanilla JavaScript and the Web Crypto API. The tools, hosted at 23232322.xyz, require no account, collect no input analytics, and transmit no user data.

Red Hat Offers Two-Node OpenShift Edge Clusters, But Capacity Trade-offs Remain

Red Hat has introduced two production-ready architectures — Two-Node with Arbiter (TNA) and Two-Node with Fencing (TNF) — that allow OpenShift edge clusters to run on just two servers instead of the traditional three. TNA uses a lightweight arbiter node to maintain quorum without carrying workloads, and reached general availability with OpenShift 4.20, while TNF relies on hardware fencing to prevent split-brain scenarios and became generally available with OpenShift 4.22 in July 2026. Both approaches are designed to cut costs at remote sites such as retail stores, clinics, and factory floors, where a third full-sized server adds significant expenses beyond just hardware. However, neither architecture changes the underlying capacity math: when one of the two workload-bearing nodes fails, only a single node remains to handle all production workloads. The two topologies preserve cluster availability in a degraded state but do not replicate the N+1 failure capacity that a standard three-node cluster provides.

How YouTube's Upload, Transcoding, and CDN Architecture Works at Scale

A technical breakdown published on DEV Community explains how a YouTube-like platform separates its write and read paths to handle massive scale. The write side uses a resumable, chunked upload system that sends video files directly to blob storage, followed by a queue-driven transcoding pipeline that converts raw footage into multiple resolutions and formats. The read side relies entirely on a CDN edge network to serve billions of daily video segment requests without overwhelming origin servers. Adaptive bitrate streaming via HLS or DASH allows video players to dynamically adjust quality based on available bandwidth. View counts are handled through approximate aggregation rather than per-view database writes, keeping the system performant under extreme load.

Phishing Costs Firms $10.5B Annually — Here Is Why It Keeps Working

Phishing attacks cost organizations $10.5 billion in 2022, a figure that rose from the prior year despite widespread email security improvements and awareness training. Experts attribute phishing's persistent success to its exploitation of human psychology, including authority bias, urgency-induced tunnel vision, and visual familiarity with trusted brands. Attackers have also evolved technical tactics such as subdomain spoofing, homograph domain tricks, and context-harvested personalization to bypass modern filters. Conventional annual phishing simulations largely fail because skills learned in low-stress test environments do not transfer to real, distracted work conditions. Security professionals recommend practical workflow changes — including password managers, app-based two-factor authentication, and independent verification of unusual requests — as more effective defenses.
