From Paper Traces to Abstract Syntax Trees: Code Similarity Then and Now

The history of code similarity detection is a story of escalating arms races. What started with professors reading printouts has evolved through Unix diffs, token-based fingerprinting, and into modern abstract syntax tree analysis. This retrospective traces the key technical shifts that shaped how we detect code plagiarism in programming courses today.

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.

How a TA Spots Refactored Code in 300 Java Submissions

Teaching assistants often face the challenge of detecting code plagiarism when students refactor submissions to evade similarity checkers. This article profiles one TA's workflow using AST-based analysis and structural fingerprinting to catch plagiarized code in a large introductory Java course, with practical techniques applicable to any programming educator.

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.
