HVACLogic Launches Free, Offline Browser Tool Suite for HVAC Engineers

·2 views

A new open-access engineering platform called HVACLogic has been developed for HVAC designers, commissioning technicians, and trade educators. The suite offers 21 specialized tools across five disciplines, including duct sizing, load calculations, refrigeration diagnostics, and building science. All calculations run entirely in the user's browser with no data tracking, no required accounts, and no cloud dependency. A service worker cache layer allows the tools to function offline in field environments like equipment rooms and basements. The platform uses established standard formulations such as ASHRAE psychrometrics and the Colebrook-White equation, with validation benchmarks documented in a publicly archived whitepaper.

Platform Team Debunks Scrum Myths After Struggling With Infrastructure Sprints

An eight-engineer infrastructure platform team spent four months applying Scrum to Kubernetes-heavy work, only to find that sprint velocity metrics created a false sense of predictability. A particularly difficult sprint — derailed by a certificate rotation, flaky cloud nodes, urgent access requests, and a production database issue — saw completed points drop from an average of ~32 to just 14. The team identified key planning failures: treating externally blocked tickets as equivalent to active work, and quietly rolling unfinished cards forward instead of recording interruptions honestly. After reforming their process to include a single Sprint Goal, reserved capacity for operational work, and transparent dependency tracking, their completion rate stabilised around 73%, down from a misleading 82%. The team concluded that Scrum can surface expectations but cannot convert unknown work into known work, and that honest forecasting is more valuable than tidy sprint numbers.

How to test FastAPI routes without hitting the database using dependency overrides

FastAPI's dependency_overrides feature allows developers to replace database and authentication dependencies during testing without using Python's patch utility. Unlike patch, which fails because FastAPI resolves dependencies at import time, dependency_overrides works directly with the function object registered on the app. Developers can override get_db with an in-memory test session, and override get_current_user with a mock user to test protected routes without generating real JWTs. A critical teardown step—calling app.dependency_overrides.clear()—is necessary after each test, since the app is a module-level singleton and leftover overrides can silently affect the entire test suite. The technique is suited for testing endpoint wiring, but not a substitute for dedicated database tests that verify constraints, migrations, and transaction behavior.

How to Securely Upload Files to AWS S3 from Flutter Web and Mobile

A developer guide published on DEV Community outlines a secure method for uploading files to AWS S3 from Flutter apps on both web and mobile platforms. The approach uses presigned URLs generated by a backend server, ensuring AWS credentials are never exposed in the client app. The author warns against the common but insecure practice of embedding AWS access keys directly in Flutter code, which can be easily extracted by decompiling the app or inspecting browser dev tools. The implementation requires only the http package in Flutter and works consistently across Android, iOS, and web, with an additional CORS configuration needed on S3 for web builds. The method was developed from a real-world delivery app project, where it also reduced data costs by enabling direct client-to-S3 uploads instead of routing files through a backend proxy.

Developer builds DNS query tool from scratch to explain protocol internals

A developer has published a hands-on guide explaining how DNS works by building a simplified version of the dig command-line tool from scratch in C. The project, hosted on GitHub under ecekaptan/dig-from-scratch, walks through the raw byte structure of DNS packets, covering headers, flags, question sections, and answer records. A DNS lookup consists of just two packets — a query and a response — each following a fixed five-part structure with no padding or separators, using big-endian byte ordering. The 12-byte header encodes six 16-bit fields including a transaction ID, flag bits, and counts for questions and answers. The guide pays particular attention to the FLAGS field, breaking down individual bits such as Recursion Desired and Response Code to show exactly how a client and server communicate intent and status.
