This is the sixth release candidate for the 0.1.0.x series. This is an
actual release candidate--it's going to be the final release if there
are no bugs--we promise. :) We fixed the last known major problems:
we don't use threading on netbsd now, and the new libevent 1.1 detects
and disables the broken kqueue that ships with OS X 10.4.0.

Libevent 1.1 also has __significant__ performance improvements if you're
using poll or select. Try it, you'll like it.

Please report any bugs, either in the installers or in Tor operation, so
we can get it perfect for an actual release: http://bugs.noreply.org/tor

http://tor.eff.org/download.html

  o Bugfixes:
- Implement --disable-threads configure option. Disable threads on
  netbsd by default, because it appears to have no reentrant resolver
  functions.
- Apple's OS X 10.4.0 ships with a broken kqueue. The new libevent
  release (1.1) detects and disables kqueue if it's broken.
- Append default exit policy before checking for implicit internal
  addresses. Now we don't log a bunch of complaints on startup
  when using the default exit policy.
- Some people were putting "Address  " in their torrc, and they had
  a buggy resolver that resolved " " to 0.0.0.0. Oops.
- If DataDir is ~/.tor, and that expands to /.tor, then default to
  LOCALSTATEDIR/tor instead.
- Fix fragmented-message bug in TorControl.py.
- Resolve a minor bug which would prevent unreachable dirports
  from getting suppressed in the published descriptor.
- When the controller gave us a new descriptor, we weren't resolving
  it immediately, so Tor would think its address was 0.0.0.0 until
  we fetched a new directory.
- Fix an uppercase/lowercase case error in suppressing a bogus
  libevent warning on some Linuxes.

  o Features:
- Begin scrubbing sensitive strings from logs by default. Turn off
  the config option SafeLogging if you need to do debugging.
- Switch to a new buffer management algorithm, which tries to avoid
  reallocing and copying quite as much. In first tests it looks like
  it uses *more* memory on average, but less cpu.
- First cut at support for "create-fast" cells. Clients can use
  these when extending to their first hop, since the TLS already
  provides forward secrecy and authentication. Not enabled on
  clients yet.
- When dirservers refuse a router descriptor, we now log its
  contactinfo, platform, and the poster's IP address.
- Call tor_free_all instead of connections_free_all after forking, to
  save memory on systems that need to fork.
- Whine at you if you're a server and you don't set your contactinfo.
- Implement --verify-config command-line option to check if your torrc
  is valid without actually launching Tor.
- Rewrite address "serifos.exit" to "localhost.serifos.exit"
  rather than just rejecting it.

Three Years of A New Kind of Science

2005-05-15 Thread Stephen Wolfram
Today it is three years since I published my book A New Kind of
Science. It seems like a lot longer than that--so much has
happened in the intervening time. What started as a book is
steadily emerging as a major intellectual movement with its own
structure and community.

The first year after the book came out was dominated by a
certain amount of "paradigm shift turbulence." But by the second
year, many serious projects were starting, and indicators like
the publication rate of NKS-based papers began to climb.

Now, in the third year, a recurring theme has been the emergence
of a growing group of exceptional individuals who are planning
to base their careers on NKS. There are scores of NKS-based
Ph.D. theses underway, and all sorts of NKS-based corporate
ventures--as well as our own growing NKS R&D operation in
Boston.

Later this year, the first full-length independent book based on
NKS will be published, and the first independent NKS conference
will be held. In late June, we will be holding our third annual
NKS Summer School--for which there were a record number of
exceptional applicants. We are planning to have our next major
NKS conference in spring 2006; we'll be announcing the details
shortly. There will also be an NKS mini-course at our Wolfram
Technology Conference this October.

This year I myself have mostly been in a tool-building phase,
working on major new Mathematica technology that, among other
things, will be very important for NKS research--and which I
can't wait to use.

There's a lot more in the pipeline too. We're developing plans
for a new kind of publishing medium for NKS (partly based on the
Complex Systems journal that I've been publishing since 1986).
We're also planning later this year to start regular "live
experiments," in which I'll be leading public web-conferenced
explorations into the computational universe.

Also in the next few months we're planning to release a rather
unexpected consumer-oriented application of NKS, which I expect
we'll all be hearing quite a bit about.

As we begin the fourth year of NKS, I feel more optimistic than
ever before about its promise--and its significance in science,
technology, the arts, and beyond. It will be fascinating to see
where the most important NKS-based breakthroughs come from, and
what they will be.

I hope you'll have the opportunity to take part in the
excitement of the upcoming years of early NKS growth.
