The smartmontools package contains two utility programs (smartctl and smartd) to control and monitor storage systems using the Self- Monitoring, Analysis and Reporting Technology System (SMART) built into most modern ATA and SCSI hard disks. In many cases, these utilities will provide advanced warning of disk degradation and failure.
Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger.
Sos is a set of tools that gathers information about system hardware and configuration. The information can then be used for diagnostic purposes and debugging. Sos is commonly used to help support technicians and developers.
The default freedesktop.org sound theme following the XDG theming specification. (http://0pointer.de/public/sound-theme-spec.html).
SoundTouch is a LGPL-licensed open-source audio processing library for changing the Tempo, Pitch and Playback Rates of audio streams or files. The SoundTouch library is suited for application developers writing sound processing tools that require tempo/pitch control functionality, or just for playing around with the sound effects. The SoundTouch library source kit includes an example utility SoundStretch which allows processing .wav audio files from a command-line interface.
This program, given a source file, produces a document with syntax highlighting. At the moment this package can handle : Java, Javascript, C/C++, Prolog, Perl, Php3, Python, Flex, ChangeLog, Ruby, Lua, Caml, Sml and Log as source languages, and HTML, XHTML and ANSI color escape sequences as output format.
SoX (Sound eXchange) is a sound file format converter SoX can convert between many different digitized sound formats and perform simple sound manipulation functions, including sound effects.
The SoX Resampler library `libsoxr' performs one-dimensional sample-rate conversion -- it may be used, for example, to resample PCM-encoded audio.
SpamAssassin provides you with a way to reduce if not completely eliminate Unsolicited Commercial Email (SPAM) from your incoming email. It can be invoked by a MDA such as sendmail or postfix, or can be called from a procmail script, .forward file, etc. It uses a genetic-algorithm evolved scoring system to identify messages which look spammy, then adds headers to the message so they can be filtered by the user's mail reading software. This distribution includes the spamd/spamc components which create a server that considerably speeds processing of mail. To enable spamassassin, if you are receiving mail locally, simply add this line to your ~/.procmailrc: INCLUDERC=/etc/mail/spamassassin/spamassassin-default.rc To filter spam for all users, add that line to /etc/procmailrc (creating if necessary).
Speex is a patent-free compression format designed especially for speech. It is specialized for voice communications at low bit-rates in the 2-45 kbps range. Possible applications include Voice over IP (VoIP), Internet audio streaming, audio books, and archiving of speech data (e.g. voice mail).
