Is your VirtualBox reading your E-Mail? Reconstruction of FrameBuffers from VRAM

This document describes a method of reading and displaying previously used framebuffers from a variety of popular graphics cards. In all 4 tested laptops the content of the VRAM was not erased upon reboot. It is also possible to show that the content of the host VRAM can be accessed from a VirtualBox guest, thereby leaking possibly confidential information from a trusted host into an untrusted guest machine.

Code critics in java PMD

PMD scans Java source code and looks for potential problems like:

Possible bugs – empty try/catch/finally/switch statements

Dead code – unused local variables, parameters and private methods

Suboptimal code – wasteful String/StringBuffer usage

Overcomplicated expressions – unnecessary if statements, for loops that could be while loops

Duplicate code – copied/pasted code means copied/pasted bugs
