Do AST-Based Engines Catch More Refactored Cheating Than Token-Based Ones

A mid-sized university CS department ran a controlled study comparing AST-based and token-based plagiarism detection across student assignments that had been systematically refactored. The results reveal which technique handles control flow restructuring, identifier renaming, and method reordering — and where both fail entirely.

A Checklist for Evaluating AI Code Detection Tools

Not all AI detection tools are created equal, and a single "accuracy" number is dangerously misleading. This article provides a practical, seven-point checklist for evaluating AI-generated code detectors, covering everything from cross-language support and prompt sensitivity to campus-specific deployment constraints.

When Is Peer Similarity Enough in a Plagiarism Checker

Source code plagiarism detection relies on two fundamentally different reference sets: peer submissions and the open web. This article examines the trade-offs between each approach, when one method catches cheating the other misses, and how to build detection strategies that combine both for maximum coverage.

Can Dev Teams Trust Code Similarity for IP Theft Detection

Code similarity analysis has long been a staple of academic integrity enforcement, but enterprises face a harder problem: detecting IP theft, insider leaks, and unlicensed reuse in complex, multi-repo codebases. This post examines the practical limitations and proper applications of similarity detection for proprietary software, from AST comparison to dependency graph analysis.

Your Static Analysis Tool Is Lying to You About Code Smells

The industry's obsession with counting "code smells" is a dangerous distraction. We're measuring the wrong things, creating false confidence, and missing the systemic rot that actually slows down development. It's time to stop trusting the simplistic metrics and start analyzing what really matters: semantic duplication and logical debt.

Your AI Detection Tool Is Probably a Random Number Generator

The market is flooded with tools claiming to spot AI-written code with 99% accuracy. Most are built on statistical sand. We dissect the eight fundamental flaws, from dataset contamination to meaningless confidence scores, that render their outputs little better than a coin flip for serious applications.

Your Static Analysis Tool Is Lying to You About Code Smells

A 2024 study of 12 million static analysis warnings found that the majority of flagged "code smells" have zero correlation with actual defects. We're drowning in false positives, wasting developer time, and missing the real architectural rot. It's time to audit your tool's configuration before it audits your team's productivity.

Your Students Are Copying Code You Can't See

A student submits a perfectly functional binary search tree. The logic is flawless, but the variable names are gibberish and the structure is bizarrely convoluted. It passes MOSS with flying colors. This is obfuscated plagiarism, the most sophisticated form of academic dishonesty in computer science. We're entering an arms race where simple token matching is no longer enough.

Your Static Analysis Tool Is Lying to You About Security

Static analysis tools promise a fortress of security but often deliver a Potemkin village. They generate thousands of warnings while missing the subtle, architectural vulnerabilities that lead to real breaches. This deep-dive exposes the fundamental gaps in token-based scanning and charts a path toward analysis that actually understands code intent and data flow.
