memtester is a user-space utility for testing the memory subsystem in a computer to determine if it is faulty. It does a good job of finding intermittent faults and non-deterministic faults. It has many tests to help catch borderline memory. memtester should compile and run on any 32- or 64-bit Unix or Unix-like system.
FTPL (FakeTime Preload Library, aka libfaketime) intercepts various system library calls and tricks programs of your choice into seeing a faked system time without having to change the time system-wide. This can be used for running legacy software with Y2K bugs, testing software for year-2038 compliance, debugging time-related issues such as expired SSL certificates, and using software that ceases to run outside a certain time frame. The faked time can be specified either absolutely or relative to the real current time, and optionally also affects file timestamps. The faked clock continues to run, but can optionally be frozen, slowed down, or made faster. A wrapper script "faketime" simplifies the usage, similar to tools such as fakechroot.
ProcMeter3 is a program for monitoring the system status and other information and displaying it in a series of graphs or as text. Most of the information comes from the /proc filesystem (cpu usage, load average , processes information, memory usage, network traffic, interrupts etc.). Other information is available for other sources (date, time, email status, log file length, disk status etc.). The program is modular and highly configurable.
mpt-status is a query tool for accessing the running configuration and status of LSI SCSI HBAs. It is a heavily modified version of the original mpt-status-1.0 tool written by Matt Braithwaite. It allows you to monitor the health and status of your RAID setup. Currently supported and tested HBAs are the LSI 1030 SCSI RAID storage controller and LSI SAS1064 SCSI RAID storage controller. Since the tool uses the MPI (message passing interface), chances are high that the basic information regarding RAID status will be available for all LSI-based controllers.
memtest86+ is a memory tester which is based on memtest86 v3.0, and provides an up-to-date version of this useful tool, which aims to be as reliable as the original. It has been fixed to work on AMD64 systems, and also properly detects all current CPUs and motherboard chipsets. It supports ECC polling for AMD64, i875P, and E7205, and displays some useful settings for the most popular chipsets.
The RegLookup project is devoted to direct analysis of Windows NT-based registry files. RegLookup provides command line tools, a C API, and a Python module for accessing registry data structures. The project has a focus on providing tools for digital forensic examiners (though it is useful for many purposes), and includes algorithms for retrieving deleted data structures from registry hives.
