Free ck software for linux

Kits JavaScript Brainf*ck Interpreter is a rather fast interpreter for the Brainf*ck esoteric programming language.

schedtool project was born, because there was no tool to change or query CPU-scheduling policies under Linux. Support for CPU-affinity has also been added and most recently (re-)nicing of processes. Thus, schedtool is the definitive interface to Linuxs scheduler.
It can be used to avoid skipping for A/V-applications, to lock processes onto certain CPUs on SMP/NUMA systems, which may be beneficial for networking or benchmarks, or to adjust nice-levels of lesser important jobs to maintain a high amount of interactive
responsiveness under high load.
All output, even errors, go to STDOUT to ease piping.
If you dont know about scheduling policies, you probably dont want to use this program - or learn and read "man sched_setscheduler".
Certain modes (as of this writing: SCHED_BATCH and SCHED_ISO) need a patched
kernel.
Main features:
- query and alter a process scheduling policy
- specifically: _normal | _fifo | _rr | _batch | _iso
- set static priority needed for _fifo | _rr
- behaves better with newer -ck kernels and sched_iso
sched_batch
improve performance of long_running processes
improve performance of multiple cpu_hog processes
sched_fifo | _rr
fine_tune system for realtime_usage
cpu_affinity
avoid cache_bounces | scheduling_overhead
fully utilize dual_cpu_machines on network_load
lock processes to certains cpus at your wish
Enhancements:
- Installing the man page works again.
- Many typos have been corrected.

This is an excellent widget set for Tcl which retains much of the Tk syntax, but uses curses to render the widgets in a character-cell terminal instead of X and a graphical display.

Installation

1. Type "./configure". This runs a configuration script made by GNU autoconf, which configures Ck for your system and creates a Makefile. The configure script allows you to customize the configuration to your local needs; for details how to do this, type "./configure --help" or refer to the autoconf documentation (not included here).

The following special switches are supported by "configure":

--enable-shared If this switch is specified Ck will compile itself as a shared library if configure can figure out how to do this on this platform.

--with-tcl Specifies the directory containing the Tcl binaries and Tcls platform-dependent configuration information. By default the Tcl distribution is assumed to be in "../../tcl8.0".

2. Type "make". This will create a library called "libck.a" or "libck8.0.so" and an interpreter application called "cwsh" that allows you to type Tcl commands interactively or execute scripts.

3. Type "make install" to install Cks binaries, script files, and man pages in standard places. Youll need write permission on the install directories to do this. If you plan to install the libraries, executables, and script files whitout documentation, use "make install-binaries" and "make install-libraries".

4. Now you should be able to execute "cwsh". However, if you havent installed Ck then youll need to set the CK_LIBRARY environment variable to hold the full path name of the "library" subdirectory. If Ck has been built as shared library, you have to set the LD_LIBRARY_PATH to include the directory where "libck8.0.so" resides.

So far, Ck8.0 has been successfully tested on various Linux distributions, on FreeBSD 3.3 with manually adapted Makefile, and on Windows NT 4.0 with a modified PDCURSES library. The Ck8.0 source tree should be able to be combined with Tcl7.4, 7.5, 7.6, and 8.0. Older version of Ck (which use Tcl7.4 or Tcl7.5) are in use for several years on HP-UX, AIX, and DEC Unix.

Pygments aims to be a generic syntax highlighter for general use in all kinds of software such as forum systems, wikis or other applications that need to prettify source code.
Main features:
- a wide range of common languages and markup formats is supported
- special attention is paid to details that increase quality by a fair amount
- support for new languages and formats are added easily
- a number of output formats is available, presently HTML, RTF, LaTeX and ANSI sequences
- it is usable as a command-line tool and as a library
- ... and it highlights even Brainf*ck!
Enhancements:
- This release just contains some bugfixes from 0.8, no new features.

PATH is a very different programming language than what you are probably used to if youre an average programmer. If youve programmed in the language Brainf*ck, youll recognize the memory cell architecture. Also, Befunge programmers will recognize the two-dimensional way that PATH programs are laid out.

PATH programs are laid out on a two-dimensional grid. It follows a path of instructions on the program grid, turning 90 degrees when instructed to (hence the name). A character recognized by the interpreter is called an instruction symbol.

To show you what a PATH program actually looks like, heres a simple program that coincidentally spells out the word "PATH" in large ASCII art letters. (You may recognize it from the PATH program homepage, and its also included with the interpreter.) All it does is make the console beep. Ill explain it in detail later, once you know what all the instruction symbols do.

The interpreter starts at the first "$" symbol it finds and starts heading right. Every time it encounters a valid instruction symbol, it executes it. When it encounters certain special symbols, it may turn in another direction.

The interpreter keeps going until it reaches a "#" symbol. If it encounters a character that is not a valid instruction symbol, it ignores it and skips over it.
