After your remote debugging connection is established, it’s time to solve real-world problems. In this second part, Christoph Sterz demonstrates how to use your remote debugging setup to act as if you were running the code directly on your desktop.

Christoph dives into a real-world scenario: a ship navigation app that crashes on the target device. You'll see how to catch a segmentation fault, interpret stack traces, and identify common pitfalls like lambda lifetime issues in Qt. He also wraps up with QML #profiling, showing you how to pinpoint performance bottlenecks and slow frames directly on the #hardware.

This video covers:
- Remote GDB Workflow: Using target extended-remote to catch crashes in real-time.
- #Debugging Case Study: Solving a classic lambda reference error that only crashes on hardware.
- QML #Performance: How to profile startup costs and runtime frame rates on the device.
- Safety Warning: Best practices for enabling #QML debugging in secure environments.

Lil' something for the night owls.

I put my alt text debugging bookmarklet into GitHub. Clicking it will add red/yellow/green (configurable) outlines to images based on their alt text status and make alt texts visible below images so you can quickly check that everything looks good.

"Works on my machine" is a luxury you rarely have in #embedded development. To fix bugs effectively on your target hardware, you first need the right infrastructure. In this video, Christoph Sterz explains the essential setup required for professional-grade embedded #debugging.

Christoph starts by demystifying debug symbols: where they are hidden in your SDK, how to manage "split debug" files in #Yocto, and how to use elfutils to handle your binaries. Finally, he walks through the setup for remote debugging using gdbserver, allowing you to keep your heavy symbol files on your laptop while controlling the application running on your device.

In this video:
- Why debug symbols are non-negotiable and how to find them in your #SDK.
- Managing "stripped" vs. "unstripped" binaries using file, eu-strip, and eu-unstrip.
- Strategies for limited storage: Partial debugging vs. remote debugging.
- Configuring gdbserver and gdb for a seamless remote connection.

🚀 Ah, #DuckDB, the savior for those who mistakenly thought their laptops could handle 100GB of #CSV files without turning into smoldering piles of silicon. Now with the added complexity of #Clojure, because every data scientist dreams of #debugging Lisp syntax when they could have just bought a server. 🤦‍♂️

Memory-safe doesn't mean crash-proof. When the JVM crashes, Java abstractions disappear. Ravali Yatham & Gireesh Punathil show how to reverse-engineer native crashes and uncover the real root cause.

Before you retry

Before retrying an AI API request, save 5 fields: requested model, final source, failure class, usage + cost, and proof of one settlement. A 200 alone is not diagnosis or billing proof.

I just added a new person to our QA team for H3VR2. As soon as they get access to the build they *immediately* soft-lock it by somehow triggering a grenade in the intro sequence causing a death->respawn-> death loop.

We have definitely found the right person!

In one of my student jobs, my supervisor used to add >>> to the beginning of debug messages. ~20 years later and I still do it: it helps to directly see what I'm looking for.
