NoBug is a library which provides assertions, logging statements, and annotations for C and C++ programs. It includes pre-/post-condition and invariant checks, as well as generic assertions. Checks are enabled based on build-levels and scope tags. It also includes debugger support (valgrind), dumping of data structures, logging your application's activities, runtime customizable logging via environment variables, different logging targets (ringbuffer, stderr, syslog, debugger, etc.), and annotation of your source code regarding known bugs, things to do, and planned things. It can track resources and detect deadlocks.
Logapp is a wrapper utility that helps supervise the execution of applications that produce heavy console output (e.g. make, CVS, and Subversion). It does this by logging, trimming, and coloring each line of the output before displaying it. It can be called instead of the executable that should be monitored; it then starts the application and logs all of its console output to a file. The output shown in the terminal is preprocessed, e.g. to limit the length of printed lines and to show the stderr output in a different color. It is also possible to automatically highlight lines that match a certain regular expression. The output is therefore reduced to the necessary amount, and all important lines are easy to identify.
Seetxt is a lightweight text file and man page viewer for X windows. It maintains "document meta-data" for each user, allowing them to automatically keep bookmarks and highlights for read-only system files. It also has a "server mode" so that command line requests can be sent to a single running server rather than starting multiple instances. Other features include hypertext-style apropos (man page) searches, file monitoring, multi-level regular expression searching, a command history, and nice little toggle lights on the interface for the server and file monitor. There's also cross-application drag-n-drop support, and handy little features that allow you to view the output of shell commands and process the text buffer with an external command (sed, awk, grep, perl, etc.) Seetxt is POSIX compliant.
liblognorm is a tool to normalize log data. It takes logs in different formats as input and outputs the data within them in a single, consistent format. For example, if you have traffic logs from three different firewalls, liblognorm will be able to normalize all the events into a generic form. Among other features, it can extract source and destination IP addresses and ports and make them available via well-defined fields. The result is that a common log analysis application will be able to work on that common set independently from the actual firewalls feeding it. Even better, once a well-understood interim format exists, it is also easy to convert that into any other vendor specific format, so that you can use that vendor's analysis tool.
mcelog is a daemon to handle machine check events (hardware errors) on x86-64 machines running an x86 Linux kernel. It accounts and logs CPU and memory errors, supports triggers on error thresholds, and can predictively offline memory pages and CPUs based on error trends. This daemon should run on all x86 Linux systems that want to handle hardware errors.
MegaTunix is a tuning application for the MegaSquirt EFI (Electronic Fuel Injection) ECU, a semi-open design hardware fuel injection controller usable on just about any internal combustion engine. It supports most recent MegaSquirt firmwares for the MS-1, MS-2, and MS-2 Extra series. Also included is support for the JimStim ECU debugging tool and the 3rd party Performance Injection System (PIS) firmware retrofit for GM ALDL ECUs. MegaTunix includes an intelligent ECU interrogator, very flexible data logging, and a configurable and extendable GUI.
