Galileo OSNMA and HAS bring authentication and precision to embedded GNSS systems

·1 views

The European Union's Galileo satellite system offers two advanced services — OSNMA and HAS — that go beyond standard positioning for embedded applications. OSNMA allows compatible receivers to verify the authenticity of Galileo navigation signals, helping protect against spoofing, though it does not prevent jamming. Galileo HAS delivers free, globally available high-accuracy corrections via satellite and internet, targeting decimetre-level positioning performance. Together, these services enable developers to build more resilient Positioning, Navigation and Timing (PNT) systems for drones, vehicles, robots and industrial infrastructure. Development boards, Linux platforms and software-defined radios allow engineers to prototype and validate such systems before committing to a final hardware design.

Developer builds free no-signup GPS altitude finder as a Progressive Web App

A solo developer has launched Zirvə, a free Progressive Web App that displays a user's elevation above sea level without requiring an account, installation, or ads. The app primarily uses the Open-Meteo terrain elevation API for accuracy within 1–3 meters, falling back to the device's raw GPS altitude reading when offline. Because GPS chips measure vertical position far less reliably than horizontal position, the app clearly labels GPS-sourced readings as approximate to avoid misleading users. A service worker enables the app to load from cache when there is no internet connection, making it usable in remote areas such as above the treeline. The developer plans to add an elevation profile for tracked sessions and explore barometric pressure as an additional offline fallback.

Why Python's subprocess.terminate() Often Fails to Kill Child Processes

When a deployment script exits cleanly, child processes it spawned can silently keep running, holding ports or file locks and breaking subsequent deploys. Python's process.terminate() sends a SIGTERM signal, which is merely a request that the target process can ignore, defer, or handle in unexpected ways. The process.kill() method sends SIGKILL, which the kernel enforces unconditionally, but it must be used as a fallback after SIGTERM times out. A further complication arises when shell=True is used or when child processes spawn their own subprocesses, since the signal reaches only the direct child and not the entire process tree. A reliable termination pattern requires sending SIGTERM first, waiting with a timeout, escalating to SIGKILL if needed, and accounting for grandchild processes to ensure nothing is left running.

AI Is Reshaping Software Engineering — But Human Judgment Still Matters

Since ChatGPT launched in November 2022, AI tools have dramatically lowered the barrier to building software, enabling non-programmers to create custom applications and automate tasks that once required professional developers. Large language models have made prototyping faster and cheaper, allowing individuals and small businesses to validate ideas without deep technical knowledge. However, one software engineer argues that understanding code fundamentals remains essential, as human judgment is needed to evaluate AI-generated code for security, scalability, and performance. AI has also transformed how developers study, offering more interactive and personalized learning experiences than traditional methods. The author cautions that while AI will keep improving, engineers should filter out the constant hype and focus on building durable skills rather than chasing every new tool or model.

How to Test TypeScript AI Agents Without Making Real Model API Calls

Developers building AI agents in TypeScript often skip proper testing, relying on live runs that can miss critical failures like runaway loops or malformed tool responses. A lightweight interface called ModelClient can be used to inject a scripted fake client during tests, replacing real API calls entirely. The scripted client replays predefined responses in sequence, records all outgoing requests, and clamps to its last step to simulate infinite-loop scenarios safely. This approach allows developers to assert on turn limits, budget checks, and tool result pairing before any broken request reaches the API. The technique keeps production code unchanged while making edge-case agent behaviour fully testable in isolation.
