LEUCHTTONNE?

I'm hoping to find more information about a Bletchley Park anecdote that I
heard a while back, which went something along the lines of:

"In order to effect an attack on a certain cipher, a crib of a special form was
required, namely, that two pairs of repeated, adjacent letters occurred in the
plaintext spaced an odd number of places apart. A German language expert
suggested 'LEUCHTTONNE', with repeated pairs 'TT' and 'NN', meaning
'lightbuoy'. In order to induce this crib, it was arranged for an actual
lightbuoy to be bombed; it was fairly certain that the resulting German
messages would include the word."

I don't suppose anyone has a source for this anecdote, or knows what the
codebreaking technique was which required this property?

OBITUARY - Peter Twinn

All...

On 17 November Martin Postranecky posted extracts from Peter Twinn's
obituary from The Daily Telegraph of that date and then a week later
posted a similar extract from the obituary that appeared in The Times.

Thank you Martin.

Somewhat tardily - I've been travelling - I finally got around to
reading the complete print version from each these two respected
publications to find that, in both instances, the newspaper in
question managed to misspell the name of Dillwyn Knox..!

Admin: Autoresponders and lists

This is an administrative note.   Sorry that this always come in the
form of scolds, but I guess that is when these notes are needed.

Those of you who don't use autoresponders can ignore this message.

Those of you who use autoresponders, but use them in a list-friendly
way can ignore this message.

List subscribers who use some kind of autoresponder (eg, out-of-office,
vacation, anti-spam challenge/response systems) need to configure their
systems to behave appropriately when getting mailing list message.  As
it happens, I actually have a rant about this at

  http://www.goldmark.org/netrants/auto-resp/

on the topic, but it hasn't been updated to address the question of
anti-spam challenge/response systems, which are spreading.

I will have to remove addresses from the list if their autoresponders
continue to behave obnoxiously to list posters.

Oh, and sorry for my long absence in dealing with admin things.  I'll
try to start to try to begin to take on my responsibilities again.

Cheers,

-j

New Colossus article

Some will be interested in Jack Copeland's "Colossus: Its Origins and Originators in the IEEE Annals of the
History of Computing (26:4, October-December 2004), pp. 38-45, available online to Computer Society members.

Re: New Colossus article

All...

There is another article that may be of interest in that it touches
[very briefly] on Colossus:

Museum of secrets to open warfares bag of tricks
------------------------------------------------
Michael Tillotson

BY THE end of this month, the trustees of the Intelligence Corps Museum
hope to have raised the first £450,000 of the £1.25 million required to
carry this intriguing project to conclusion  although, of course, no
museum can ever claim to be complete. Earlier this year, the Duke of
Edinburgh, Colonel-in-Chief of the Intelligence Corps, became the patron
of the project and MoD funds were authorised to provide for three
professional staff alongside existing volunteers.

The original museum was founded in 1970 in Ashford, Kent, but relocated in
1997 to Chicksands, Bedfordshire, virtually the centre of a cluster of
intelligence-related and covert operations sites used during the Second
World War. Bletchley Park, where the German Enigma codes were deciphered,
is 13 miles to the west and Y Service operators responsible for
intercepting and passing enemy message traffic to Bletchley were housed in
huts behind the historic Chicksands Priory. Agents of the Special
Operations Executive (SOE) and the United States Office of Strategic
Services (OSS) were trained at Tempsford, ten miles to the northeast and
the Political Warfare Executive operated from the stables at Woburn Abbey.
There is a story that the Y Section work was shrouded in such secrecy that
a married couple recently visiting the museum discovered they had both

Colossus - the first electronic computer

"Colossus - the first electronic computer", a book by Jack Copeland, appears
to be available now from Amazon but there's not much by way of a description
of its contents on the Amazon website and nothing at all on the OUP's
website yet.

Has anyone seen a copy yet and can post to say if it's a good read ?

Thanks,

A.

We had a discussion in this forum on 28 November about misusing
the 'reply' feature within email software to begin a new topic,
rather than composing a new message.

There is no problem with an individual posting done in this way
but archives like <gmane.science.cryptography.bletchley-park>
display these items by thread and as a result this entry, along
with others of greater import, is now displayed under a totally
unrelated heading - and is as a consequence 'off topic!.

Incidentally: the writer must, when he refers to 'Amazon' be
referring to <www.amazon.co.uk>. Parent <www.amazon.com> refers to
the book in question as "Not yet released".

Re: Probably O/T...: Museum of secrets to open warfares bag of tricks

Might this museum be a more receptive home for Colossus and the Bombe?

PS  If this is "O/T" I give up trying to figure out what isn't.
