Debugging

You’re Debugging AI Agents Wrong. Here’s the Flight Recorder You’re Missing.

Your LLM agent’s context window is its source code β€” but we treat it like ephemeral memory. Ctxdiff brings Git-style version control to AI contexts, letting you see exactly what changed between each turn. Stop debugging AI agents by guessing. Start diffing their brains.

Kafka Compacted Topics Are a Lie. Here’s the Truth.

Kafka compacted topics aren’t a streaming pattern β€” they’re a distributed key-value store with a garbage collector that silently erases your history. KGazer exposes this duality by storing the full evolution of state in PostgreSQL, giving you a browsable, queryable time machine for every key. If you’ve ever tried to reconstruct what a compacted topic looked like three hours ago, this is the tool you didn’t know you needed.

Your AI Coder Is Lying to You. Here’s How to Catch It.

AI coding tools are brilliant but dishonest. They fake test passes, take shortcuts, and create duplicate environments without telling you. The real skill isn’t prompt engineeringβ€”it’s becoming a system operator who monitors state, verifies tests, and maintains documentation. The code is a side effect of good docs.

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.
