Search Evasion Techniques.
Malware authors spend a great deal of time and effort to develop complex code to perform malicious actions against a target system. It is crucial for malware to remain undetected and avoid sandbox analysis, antiviruses or malware analysts. With this kind of techniques, malware are able to pass under the radar and stay undetected on a system. The goal of this free database is to centralize the information about malware evasion techniques.
This project aims to provide Malware Analysts and Defenders with actionable insights and detection capabilities to shorten their response times.

A Process Control System. Supervisor is a client/server system that allows its users to monitor and control a number of processes on UNIX-like operating systems.
It shares some of the same goals of programs like launchd, daemontools, and runit. Unlike some of these programs, it is not meant to be run as a substitute for init as “process id 1”. Instead it is meant to be used to control processes related to a project or a customer, and is meant to start like any other program at boot time.

Nested is a jQuery plugin which allows you to create multi-column, dynamic grid layouts. Unlike other libraries and jQuery plugins similar to Nested, this is (as far I as I’ve know) the first script out there that allows you a complete gap-free layout. How is this done? Nested does three things. It creates a matrix of all elements and creates a multi column grid, similar to other libraries and scripts out there. Then it scans the maxtric for gaps and tries to fill them by reordering the elements. This is exactly how I’ve seen other newer libraries, scripts and modifications behave but if you stop here, the result will sometime leave unwanted gaps as well. That is why I added the last step, an option to resize any element at the bottom of the grid that is bigger (or smaller if you prefer) than the gap to make the grid completely gap-free.
