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.

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.

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.

The Open Source Audit That Nearly Bankrupted a Startup

When a promising fintech startup sought Series B funding, their technical due diligence triggered a nightmare. A deep code audit revealed a sprawling, undocumented web of open-source license violations, putting their entire intellectual property—and survival—at risk. This is the story of how they navigated the legal and technical fallout, and why your codebase might be hiding the same ticking bomb.

The 8 Code Smells That Predict Your Next Plagiarism Case

Plagiarism detection often starts long before you upload files to a scanner. Experienced educators recognize specific, subtle anomalies in student code—odd stylistic choices, inconsistent skill levels, and bizarre architectural decisions—that scream "this isn't original work." Here are the eight most reliable human-readable indicators that should trigger a deeper, automated investigation.

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 Hiding Plagiarism in Plain Sight

Plagiarism detection isn't just about matching code. Savvy students are using sophisticated obfuscation techniques—dead code injection, comment spoofing, and false refactoring—that fool standard similarity checkers. This guide reveals their methods and provides a tactical workflow to uncover the deception, preserving academic integrity in advanced courses.
