From: Aaron Isotton <aaron@isotton.com>
Subject: GPL: bz2stream 0.1.0
Date: 7 Jul 2002 06:45:21 GMT
I'm happy to announce the first release (0.1.0) of bz2stream, a set of
C++ stream classes wrapping libbzip2.
The streams do not write the data to any default destination, but to
another stream buffer. This gives you the maximun possible
flexibility. You just create a "normal" input or output stream, and
then use pass its stream buffer to the bz2 stream. The bz2 stream acts
as a filter, compressing or decompressing all the data you pass it.
For example, to read in a file and compress it to another file, a
program as the following would be enough:
#include "bz2stream.hpp"
#include <iostream>
#include <fstream>
int main(int argc, char** argv) {
std::ifstream infile(argv[1], std::ios::binary);
std::ofstream outfile(argv[2], std::ios::binary);
bz2ostream out(outfile.rdbuf());
out << infile.rdbuf();
}
The performance loss because of the use of the stream classes and not
of direct calls to libbzip2's API is virtually non existant. This
program is as fast as bzip2.
The use of the bz2 stream classes is especially easy because there are
no libraries you need to link to; you only need to include the
bz2stream.hpp header. (Of course you must link against libbz2).
This is an early release; this code is tested, but not ready for
applications where absolute reliability is a must.
bz2stream is available at http://www.isotton.com/bz2stream/. It is
released under the GNU GPL and includes HTML documentation.

Subject: sn 0.3.5 - Hassle-free Usenet news system for small sites.
Date: 7 Jul 2002 06:45:27 GMT
sn 0.3.5 is now available at <http://www.iki.fi/patrik/sn/>.
This release contains a number of bug fixes, see the CHANGES file.
What it is
==========
sn is a small news system for small sites serving perhaps a few
dozen newsgroups, and with a slow connection to the internet.
It is similar to Leafnode (<http://www.leafnode.org/>).
The target user is a home or SOHO with a single modem connection
to the Internet, maybe running IP masq or similar, and serving a
few workstations.
sn is different
===============
sn is fast. The news fetcher implements command pipelining and
parallel fetches, so high modem latency doesn't cost you.
(You can also throttle sn down, if it's too fast).
sn is flexible. You can subscribe to newsgroups on several
upstream sites, and you can create local newsgroups that are not
propagated upstream. sn can make mailing lists look like newsgroups
transparently.
sn is non-intrusive. It has no configuration files, only control
files with simple semantics, so it's suited to being run in an
automated fashion.
sn is small. It batches 10 (default) articles per file, so
conserving inodes and reducing disk block fragments. sn can also
compress the article bodies. It aliases cross posts rather
than making separate copies. It does not maintain a bulky overview
database; instead it gets overview information directly from the
articles. Spool metadata is 5% to 10% of the total spool size,
even with compression. You don't need to build a separate file
system just to spool news.
sn doesn't have to be set up for the system. You can use it
privately, and your users can maintain their own news spool without
building sn.
sn has limitations
==================
Because the news spool is in an unconventional format, news readers
can read news locally only via NNTP.
IHAVE is not supported. Use POST instead.
sn has no idea of distributions.
sn can't handle thousands of newsgroups. A hundred is comfortable.
The method sn uses to alias cross posts is similar to filesystem
symlinks rather than hard links, in that if the original article is
expired, the alias breaks.
sn doesn't know how to filter spam.
Newsgroup names are subject to the same length limitations as any
filename.
Requirements
============
sn is beta. It should work on most UNIXish systems, as long as the GNU
tools are installed. (Tested on Linux (main development platform),
Solaris and FreeBSD.) If it runs on your machine, let me know. Or if it
doesn't run.
You need zlib (<http://freshmeat.net/projects/zlib/>) if you decide to
compile in the compression feature.
You'll need inetd or tcpserver (<http://freshmeat.net/projects/ucspi-tcp/>)
to run the daemon. If you use inetd you will probably also want tcpd
(tcp wrappers).
I am interested in bug reports, comments, and suggestions.
License
=======
Distribution of sn is covered by the GNU GPL. See file COPYING.
Use of sn is not restricted. No express or implied warranty of
fitness for any purpose (but I'm still interested in bug reports
and comments).
History
=======
sn was created by Harold Tay <harold-sn at nb dot com dot sg> and maintained by him
until version 0.3.2. From 0.3.3 onwards, sn is maintained by
Patrik Rådman <patrik at iki dot fi>. For details see the CHANGES file.

Subject: [Software/Edu] Tux Paint - new version available (2002.07.07)
Date: 7 Jul 2002 20:45:18 GMT
"Tux Paint" is a free (Open Source) drawing program for young children.
It runs under Windows, Linux, and soon MacOS, Mac OS X, BeOS, and others...
The latest release, 2002.07.07, activates three items in the tool bar:
* Shapes
Draw simply polygon shapes (circles, squares, diamonds, triangles, etc.)
(Currently, outlines only. Filled shapes are coming soon.)
* Save
Save the current image so you can open it up later.
* Open
Open a saved image. (Simply a thumbnail browser; no knowledge of the
underlying operating system or filesystem structure are necessary.
Just choose the picture and click it, and it will load.)
This version is currently available as source code. Within a day or two,
a pre-compiled version for Windows will be available, as well.
Hopefully within the week, MacOS and Mac OS X versions will become
available, as well.

Changes
=======
Since version 2.7b:
Bug Fixes:
Install two DLLs for the Win32 version. Don't crash for HTTP servers that send
headers prefixed with whitespace. Make the "edit selected entry" option work.
Don't write uncompressed data to the cache with a header saying it is
compressed. Be more lenient in detecting spiders that cannot make requests.
The wwwoffle-tools programs now handle dir names as if they had http:// in
front. Disallow wwwoffle requests for protocols that WWWOFFLE does not
handle. Use the command line config filename in error messages. Fix to allow
compilation on SGI IRIX. Handle XHTML style tags when modifying HTML. Updated
setuid/setgid code. Some memory leaks removed and potential crashes removed
due to using lint).
New Features:
Split up Set-Cookie headers since browsers can't handle them.
Don't request deflated data since WWWOFFLE and servers don't agree on format.
Added a form on the monitor options page to stop monitoring a URL.
The confirm-requests option now asks for confirmation for page reloads.
Documentation:
Update FAQ to reference privoxy as well as JunkBuster.
Describe how to modify htdig templates to work with WWWOFFLE.
