Gwyddion is a modular SPM (Scanning Probe Microsope) data visualization and analysis tool. It can be used for all most frequently used data processing operations including: leveling, false color plotting, shading, filtering, denoising, data editing, integral transforms, grain analysis, profile extraction, fractal analysis, and many more. The program is primarily focused on SPM data analysis (e.g. data obtained from AFM, STM, NSOM, and similar microscopes). However, it can also be used for analyzing SEM (scaning electron microscopy) data or any other 2D data.
LE has many block operations with stream and rectangular blocks, can edit both unix and dos style files (LF/CRLF), is binary clean, has hex mode, can edit text with multi-byte character encoding, has full undo/redo, can edit files and mmap-able devices in mmap shared mode (only replace), has tunable syntax highlighting, tunable color scheme (can use default colors), tunable key map. It is slightly similar to Norton Editor, but has more features.
Linux is a clone of the Unix kernel, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. It has all the features you would expect in a modern fully-fledged Unix kernel, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and TCP/IP networking.
c++-gtk-utils is a lightweight library containing a number of classes and functions for programming GTK+ programs using C++ in POSIX environments where the user does not want to use a full-on wrapper such as gtkmm or wxWidgets. It provides classes for managing the lifetimes of GTK+ widgets and windows that will make GTK+ exception safe, functions to make single instance programs where restarting will bring up the existing instance, smart pointer classes for memory management, thread-safe signal/slot classes with automatic disconnection, classes for using std iostreams with files opened with Unix file descriptors, functions for connecting a callback object and a Unix file descriptor to the main loop with provision for automatic disconnection, classes and functions for inter-thread communication, some convenience pthread wrapper classes., a class encapsulating anonymous Unix pipes, a class to reassemble UTF-8 sent over pipes and sockets, and classes for printing Postscript files and plain text using the GTK+ print system.
