Free some tools software for linux

stic bundles a few Linux tools which are intended to support the task of collecting an unreasonable amount of pictures (preferrably in JPEG format).
similar
a program for detecting duplicate or very similar images. It maintains a
database of characteristic color samples which it compares with submitted
pictures. similar depends on libjpeg and ImageMagick s convert (on a
modern Linux desktop system these components should already be present).
Storage medium may be a usual filesystem or a MySQL database. There
also is a MySQL UDF extension to compare image samples within SQL queries.
similar contains the communications module described at sagent.
simv
a core program to perform file management tasks on an image collection.
Its main purpose is to coordinate file movements with the content of
similars database. This applies to importing new files which get tested
against the existent collection, as well as to inform similar about moving
and deleting files within the collection.
simv depends on an external image viewer like ImageMagick s display
(should already be present on a modern Linux desktop system) or John
Bradleys xv (quite a fast one).
simv contains the communications module described at sagent.
sagent
a standalone version of the communications module used in simv and
similar. This software receives input from its start terminal and multiple
clients, distributes several types of output back to them, and is also
able to act itself as such a client.
Since communications mainly use TCP/IP there is an encryption layer
(Blowfish with 128 bit keys) which provides user authentication. Any
single activity of such a user may be particularly permitted or denied.
Secure connections should be possible that way as long as one can defend
the keyfiles and programs on client and server host against foreign
access.
Front-end connection software is available in C, Tcl/Tk and PHP3 to build
custom clients. In the most primitive case even telnet can act as a
client.
The standalone program sagent may be used as communications node in a tree
of clients. Another purpose is to be a shell frontend which sends commands
to a server and receives its replies.
snntpbatch
a command line based NNTP (newsgroups) client. It is mainly intended for
automatic download of images by use of a filter language. Nevertheless it
also downloads the message texts and converts them to HTML code which
includes the downloaded images. Also, it is capable of automatically
posting sets of images to the newsgroups.
The tools are designed to be very independent of the system flavor. On an
average Linux desktop there should be no need to update existing system
components. Actually one could use stic without having display equipment for
graphics.
Any program activity which is possible in dialog may also be performed in
batch runs. Therefore the tools are quite suitable for users who like to get
boring tasks automated and manual tasks simplified.
All tools code is open source and distributed under BSD license.

Enhancements:
- The new encrypted protocol version 0.2 is standard now : SHA-1 seal, 256 bit keys, variable chaining initialization vector.
- The protocol of a connection is chosen by the client and may or may not be accepted by the server.
- See sagent command -security options clientprotocol , serverprotocol.

SimpyTools is a collection of various software for using and enhancing the simpy.com social bookmarking service.

Simpy Tools includes libraries in various programming languages for using the REST API of simpy.com. It also includes a Firefox extension and more.

Simple wrapper-lib for accessing the http://www.simpy.com/ REST API via python. See http://simpytools.sourceforge.net for details, and libs in other languages

Synopsis:

# get and store links in files matching a query
client = SimpyClient(user, passwd)
links = client.getLinks( {limit:20, q:+tags:"programming" +tags:"trails"} )
for i, link in enumerate(links):
s = urllib2.urlopen(link.url)
if s is not None: file(str(i)+".html", w+).write(s.read())
else: print "URL "+link.url+" was not handled"

The mjpeg programs are a set of tools that can do recording of videos and playback, simple cut-and-paste editing and the MPEG compression of audio and video under Linux.
Recording is supported for the Zoran based cards like the Buz (Iomega), DC10 (MIRO, Pinnacle), Matrox Marvel cards and the LML33 (Linux Media Labs). See related pages to the right to find the right driver for your card.
The recorded videos can be converted to MPEG streams. The software playback of MPEG streams works with almost every player and every OS.
You can produce special forms of MPEG streams like VCD (Video CD) and SVCD for hardware playback.
A key design objective of the tools is interoperability with other video tools:
The tools can be used used to edit, playback and compress motion JPEG (MJPEG) AVIs captured using the xawtv package.
The tools can be used to edit playback and compress MJPEG streams created and editted with broadcast 2000. N.b. the current mpeg2movie high bit-rate MPEG encoder is in large part derived from an obsolescent snapshot of the mjpegtools MPEG encoder.
Enhancements:
- changes in YUV4MPEG2 API to offer support for multiple colorspaces (particularly useful for DV video), so that multiple planar YUV formats (also monochrome or alpha) are supported.
- most filtering tools have been adapted to support multiple YUV formats, so that you will not lose quality/precision in conversion steps.
- Many new or dramatically improved filters including (but not limited to):
*) yuvdenoise (denoising filter)
*) yuvdeinterlace (intelligent deinterlacing program)
*) y4munsharp (unsharp mask image sharpening program)
- Improvements in the IDCT/DCT routines in the MPEG-1/-2 encoder (much more exact now and not subject to overflow/truncation on the IA32 arch).
- MANY new utilties for importing/exporting data:
*) New and improved PGM/PNM conversion programs for dealing with PPM data.
*) Utilities to convert raw (headerless) YUV data to and from YUV4MPEG2 format. Useful when interfacing with other program suites.
*) Program (yuyvtoy4m) to convert 4:2:2 data from digital cameras into YUV4MPEG2 format for use with mjpegtools.
*) y4mstabilizer for stabilizing images with unsteady camera work
- Improvements and fixes in mplex for handling PCM audio (LPCM audio actually works now)
- DPME (Dual Prime Motion Estimation) in the encoder (mpeg2enc) is fully functional (it was present but buggy/artifacted in the earlier releases)
- Rate control in the encoder improved considerably.
- Much better Quicktime file handling (via libquicktime) especially the audio tracks.
- Besides the always-excellent x86 support, we now have full support for AMD64 (including MMX/SSE/etc. optimizations) and for PPC (e.g. Linux or OS/X), and win32 support is also available (via Cygwin/Mingw).

- Used COPYING, README, AUTHORS, and ChangeLog Files.
- Removed a bit of useless code.
- Decreased Filesize.
- Misc. Fixes.

cdp-tools is a software that provides tools to work with the Cisco Discovery Protocol (CDP).
They were written because of a particular hosting center that insisted on learning routes using CDP, and thusly required Cisco Switches for doing their dirty work.
cdp-listen/cdp-routemgr are proof-of-concepts that may be useful if you want to implement a similarly brain-damaged proposal.
cdp-send is a must-have tool if you are in that situation. It can pretend to be just about any kind of Cisco hardware you can imagine.
The source is a bit difficult to follow as a requirement was that it build under both the ancient libnet and the new libnet code. hence, much nasty macro-ing.
