Reducing Cold-Start Latency in Serverless Applications via Dynamic Slicing
Georgios Alexopoulos, Konstantinos Karakatsanis, Nikolaos Alexopoulos +2
We present PyXtrim, a system that reduces the cold-start latency of serverless applications through debloating. We focus on Python, a dominant language for serverless applications…
When AI Agrees Too Much: Manipulating Automated Code Review via Bias Injection
Dimitris Mitropoulos, Nikolaos Alexopoulos, Georgios Alexopoulos +1
Automated Code Review (ACR) systems integrating Large Language Models (LLMs) are increasingly adopted in software development workflows, ranging from interactive assistants to auto…
Cross-Ecosystem Vulnerability Analysis for Python Applications
Georgios Alexopoulos, Nikolaos Alexopoulos, Thodoris Sotiropoulos +3
Python packages often bundle third-party native libraries (e.g., OpenSSL), a practice known as vendoring. Identifying vulnerabilities in these libraries is challenging because curr…
PyTrim: A Practical Tool for Reducing Python Dependency Bloat
Konstantinos Karakatsanis, Georgios Alexopoulos, Ioannis Karyotakis +4
Dependency bloat is a persistent challenge in Python projects, which increases maintenance costs and security risks. While numerous tools exist for detecting unused dependencies in…
