What Open Source Licenses Actually Enforce in Court

An analysis of 47 open source license enforcement cases from 2008 to 2023 reveals surprising patterns: most violations aren't willful, GPL enforcement rarely goes to trial, and MIT license cases are rising faster than any other. Here's what the data says about what licenses actually enforce in practice versus what developers assume.

How Cross-Language Code Plagiarism Detection Actually Works

Cross-language code plagiarism presents a growing challenge for programming educators as students discover they can translate solutions between languages to evade detection. This article explains the techniques—AST normalization, semantic fingerprinting, and intermediate representation comparison—that modern tools use to catch these sophisticated cases.

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.

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.

What Code Complexity Metrics Miss About Real Maintainability

Cyclomatic complexity, lines of code, and other traditional metrics have been the gold standard for decades — but they systematically miss the factors that actually make code hard to maintain. Here is what experienced teams have learned about measuring what matters.
