Debugging

Stop Trying to Teach AI to Write Better Code. Do This Instead.

The secret to unlocking AI coding tools isn’t better prompts. It’s enforcing classical software engineering processes β€” TDD, code review, bug diagnosis loops β€” as executable constraints. Matt Pocock’s 180k-star GitHub repository shows how to turn your AI assistant from a messy intern into a disciplined senior engineer. Stop trying to make AI faster. Make it slower, on purpose.

AI Could Generate Code, But It Couldn’t Debug It. Until Now.

Cursor’s Debug mode transforms AI from a code-generating parrot into a runtime detective. Instead of guessing fixes based on training data, it inserts logging probes, collects real execution data, and diagnoses the phantom bugs that static analysis can’t see. This automates the hardest part of software engineering β€” debugging β€” and threatens to make senior debuggers obsolete.

The Vanishing Segfault: When ‘It Works Now’ Is a Lie

Every developer has experienced the phantom bug that vanishes after unrelated code changes. But that relief is a trap. The segfault didn’t fix itselfβ€”it’s merely hidden by a shift in memory layout. Without finding the root cause, you’re deferring a catastrophic failure to the worst possible moment. Learn why Heisenbugs are more dangerous than the ones that crash reliably.

Your Rust Service Isn’t Leaking – It’s Being Sabotaged by the C Allocator

Rust’s compile-time memory safety is a promise. The allocator is a loophole. The default glibc malloc hoards freed memory in thread-local caches for performance, making your service’s memory footprint grow exactly like a leak. This isn’t a bugβ€”it’s a deliberate optimization. Stop blaming your code and check the allocator.

How to Spy on Your SQLite Database Without Touching a Single Line of Code

A new open-source tool called sqlitefeed uses kernel-level uprobes to intercept every SQLite3 query your application runs β€” without modifying a single line of code. It reveals hidden queries from ORMs, third-party libraries, and embedded usage, giving developers a backstage pass to their database. No instrumentation, no recompilation, just raw visibility.

The 2 AM Heisenbug Is Dead. You Just Don’t Know It Yet.

DDB introduces source-level interactive debugging for distributed applications, letting developers step through multi-node execution as if it were single-threaded. The real breakthrough isn’t technicalβ€”it’s cognitive. While existing tools either abstract away distribution or drown you in logs, DDB collapses the complexity gap between distributed state and developer intuition, turning 2 AM heisenbug hunts into calm, linear debugging sessions.

Your ‘Safe’ Rust Code Is Just a Thin Layer Over 1970s C. Deal With It.

Every Rust program that touches the OS – parsing command-line arguments, reading environment variables, opening files – is just a safe wrapper around the same 1970s C library calls. The ‘rewrite it in Rust’ dream is an illusion at the system boundary. This article exposes the humbling truth and why embracing it makes you a better developer.
