qDecoder is a library for CGI programming.
Being a Web Application Interface for C/C++ use, qDecoder is a solution
product for developers. The Query Fetch algorithm of qDecoder based on the
linked-list provides transparency with low layers by the simple library
interface regardless of COOKIE/GET/POST(including File Upload). Thus, it
enables the web based software to be more intuitively designed and
implemented. qDecoder is developed according to the free software model and
is publicly distributed.

Sather is an object oriented language which designed to be simple,
efficient, safe, and non-proprietary. It aims to meet the needs of
modern research groups and to foster the development of a large,
freely available, high-quality library of efficient well-written
classes for a wide variety of computational tasks. It was originally
based on Eiffel but now incorporates ideas and approaches from several
languages. One way of placing it in the "space of languages" is to say
that it attempts to be as efficient as C, C++, or Fortran, as elegant
and safe as Eiffel or CLU, and to support higher-order functions as
well as Common Lisp, Scheme, or Smalltalk.
Sather has garbage collection, statically-checked strong typing,
multiple inheritance, separate implementation and type inheritance,
parameterized classes, dynamic dispatch, iteration abstraction,
higher-order routines and iters, exception handling, assertions,
preconditions, postconditions, and class invariants. Sather code can
be compiled into C code and can efficiently link with C object files.

Cilk is a language for multithreaded parallel programming based on
ANSI C. Cilk is designed for general-purpose parallel programming,
but it is especially effective for exploiting dynamic, highly
asynchronous parallelism, which can be difficult to write in
data-parallel or message-passing style. Cilk has been developed since
1994 by the Supercomputing Technologies Group at the MIT Laboratory
for Computer Science. Cilk has been used for research, teaching, and
for coding applications such as a virus shell assembly simulator and
three chess programs.

Gri is a language for scientific graphics applications. By 'language'
I mean that it is a command-driven application, as opposed to a
click/point application. It is analogous to latex or tex, and shares
the property that extensive power is the reward for tolerating a
modest learning curve. Gri output is in industry-standard PostScript,
suitable for incorporation in documents prepared by various text
processors.
Gri can make x-y graphs, contour-graphs, and image graphs. In
addition to high-level capabilities, it has enough low-level
capabilities to allow users to achieve a high degree of customization.
Precise control is extended to all aspects of drawing, including
line-widths, colors, and fonts. Text includes a subset of the tex
language, so that it is easy to incorporate Greek letters and
mathematical symbols in labels.

- The function whos() didn't work in the previous release,
for which reason there is this early bug fix release now.
- Since introduction of KShallowObjectArray in 1.32, I forgot to
increase the constant 12 to 13 in #define pair(ka,kb) ... in
objarithm.C. Result: E.g., 2/x where x is undefined did not produce
error message but silently evaluated to 0. There could be other much
more obscure errors also. Now the constant 12 is no longer
hard-coded but is defined to be int(Kundef)+1. This works as long as
Kundef remains the last in enum Tkind (object.H). There is comment
telling it... - in tela.C:FindMachineNan(), using switch()
statement can cause compile-time error due to duplicate case labels,
fixed now by rewriting switch() as nested if's (tela.C)
(This is in code segment that was put in tela only in the previous
release.)
- some changes to allow compilation with gcc-3.0 (contributed by Ch. Spiel)

New Features and Changes:
========================
o The following Vdata routines were added:
VSsetblocksize/vsfsetblsz -- sets the block size of the
linked-block element.
VSsetnumblocks/vsfsetnmbl -- sets the number of blocks for
a linked-block element.
VSgetblockinfo/vsfgetblinfo -- retrieves the block size and the number
of blocks of a linked-block element.
o Two routines were added to get compression information for the SD and
GR interfaces, including chunked elements: SDgetcompress/sfgcompress
and GRgetcompress/mggcompress.
Note:
- For a JPEG image, GRgetcompress only returns the compression type, not
the compression information (i.e, quantity and force_baseline). This
information is not currently retrievable.
- Getting compression type for JPEG chunked images is not working yet.
o "hdp dumpgr" has a new option, -pd, to print palette data only. Also,
whenever option -p or -pd is given, only palettes are printed, and no
images or file attributes.
o A new FORTRAN function, heprntf (HEprint), was added. It takes two
arguments: file name and level. If the file name string has 0 length,
then error messages will be printed to standard output.
o A memory leak in the netCDF portion of the HDF/mfhdf distribution
was fixed.
o The "#define NULL" was removed since ANSI C compilers are required to
define NULL.
o When using "hdp dumpgr", data was being printed in the range of 0-250
when it should have been between 0-168. This problem is now fixed.

Changes made from patch level 1 to patch level 2:
1. Fixed bug in -makedcls option that allowed a buffer overflow when
module names exceed 20 characters.
2. Minor changes to source code to clean it up and make it compatible
with C++.
3. Fixed bug that caused crash when number of statement labels in a
subprogram exceeded 2000.
4. Fixed bug that could cause access violation on some systems, if
program contains variable names starting with AA or AB.
5. Fixed bug in handling a labeled END DO statement that matches a
DO statement that doesn't use a label.
6. Changed license from "BSD"-like to "MIT."

- New program Iget to retrieve documents by docid
- Fixed spurious output from Isearch -t option
- Fixed score calculation for Boolean searches
- Added -l parameter to zpresent to accept docids from a file
- Fixed a bad return state that caused a segfault when no files were
found to index.
- Added improved entity replacement code to STRING class (J. Tyler)
- Improved algorithm for generating URL from path in EOS_GUIDE doctype
- Added hook for VIDB KeyLookup method
- Initial release of zpresent
- Fixed bug in EOS_GUIDE doctype which caused searches to sometimes fail
- Modified zpresent.dtd to stick the source field in the individual
result elements, rather than on the container results element.
- Added method Result::GetVKey for virtual databases so you can tell
which constituent they came from. It's an egregious hack which just
stuffs the database number at the front of the key so it can be
included in the output from zsearch and parsed by zpresent.
- Rearranged some of the XML presentation for the FGDC doctype Summary
element set
- Added a path->URL translation to EOS_GUIDE doctype to facilitate links
back to original (crawled) source documents
- Cleaned XML text of characters which should be entities
- Added zsearch program for XML search output
- Added initial version of NASA EOS/Guide doctype
- Removed some extraneous output from vidb.cxx
- Added CIPC doctype for NASA/CIP Collection metadata
- Added delimiter to Isearch output (J. Millard)
- Improved XML results presentation in FGDC doctype

changes in silc-server package:
===============================
- upgraded to version 0.8.4
- added generic startup script for Solaris and Linux (i can't test it on
Darwin/Mac OS X because i don't have any.. please let me know if it works
for you. thanks)
You will need to copy ${PREFIX}/etc/rc.d/silcd to appropriate location in
your system and do neccessary actions to enable it.
e.g. Solaris: copy ${PREFIX}/etc/rc.d/silcd to /etc/init.d/ and make links
in /etc/rc2.d/, /etc/rc1.d/, /etc/rc0.d/.
changes in silc-server since 0.8.1:
===================================
* Fixed a bug in library where sending a bogus authentication
payload would lead to a crash.
* Fixed a bug in the fetch_logging() config callback.
* Drop root privileges when started in foreground. Don't drop them
if debugging also.
* Added better error logging in rekey protocol.
* Do not check public key types in SKE during rekey.
* Fixed the rekey protocol with PFS, which was totally broken.
* Fixed a negative refcount situtuation for the config context.
* Fixed memory leaks from config object.
* Added support for adding new connections to the server in rehash.
After rehash they take effect.
* Added support for changing the maximum allowed connections in
rehash. The number can grow but going smaller is not supported.
* Added preliminary checking during config parsing for a valid
public/private key and removed further checks in the code.
* Fixed silc_net_gethostbyaddr to correctly resolve by
address.
* Fixed the notify relaying to client. The HMAC to be used
with relayed packets ws wrong and caused decryption failure
at the client end.
* Fixed the silc_log_quick handling in the logging routines.
It didn't log quickly when it was TRUE. Also the flush delay
was set even if it was 0 in config file.
* Added support for changing key pair of the server in rehash.
* Fixed the TOPIC_SET notify to not crash. It changed the topic
too early, before getting the channel entry.
* Added rehash support. Added function silc_server_rehash() that
will perform all the basic tasks of the rehashing procedure.
* Added command line option `-x, --hexdump'. This will enable the
SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
The option `--hexdump' implies `--debug'.
* Fixed a bad bug in the logging APIs (silcutil library) where
the application would crash after calling silc_log_reset_all().

changes in the silc-client package:
===================================
- upgraded to 0.8.6
- separate PLIST files for perl support and crypto modules
- make it compile on Solaris
- minor cleanups
changes in the silc-client since 0.8.3:
=======================================
* Merged irssi crash fixes on /QUIT.
* Fixed a bug in library where sending a bogus authentication
payload would lead to a crash.
* Do not check public key types in SKE during rekey.
* Fixed the Irssi SILC Client to use the silc_get_username and
silc_get_real_name insted of glib routines since the glib
routines only corrupt stack. Fixes the Irssi SILC to work in
Cygwin.
* Fixed the Irssi to not use g_get_home_dir since it crashes
or returns garbage on cygwin and corrupts stack. Added function
get_home_dir to Irssi routines.
* Fixed the KICKED notify handling in client library to
correctly remove the channel and all entries from the
channel when I was kicked. This bug crashed the client.
* Fixed yet another but in KICKED notify handling to remove
the kicked client correctly from the channel.
* Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
sources correctly to distribution. Fixes --with-gmp option.
* Removed the manual rehashing from ID Cache, and changed it
to use the SILC Hash Table's auto rehash feature.
* Fixed a bug in the silc_client_nickname_format function that
handles the multiple same nickname formatting. Two clients
with same nickname caused problems after the first one left
and rejoined. It didn't format the nickname correctly.
