[QUOTE=pinhodecarlos;522144]Also there are more than 15 different books on sale there and as such just don’t know which one to buy![/QUOTE]
The biography "Alan Turing the Enigma" by Andrew Hodges is a very good book with lots of historical and scientific details about Bletchley Park as well as the rest of Turing's life and ideas.

The Bletchley Park Report booklet series are also good on historical details.

Britain's National Museum of Computing is on the same site but now has a separate entrance after becoming independent.

Fantastic Nick, much appreciated.

[QUOTE=Nick;522146]The biography "Alan Turing the Enigma" by Andrew Hodges is a very good book with lots of historical and scientific details about Bletchley Park as well as the rest of Turing's life and ideas.[/QUOTE]I own this book and have found it immensely difficult to read it. I've tried on several occasions but always gave up after an hour or so.

Part of the problem with the work is, IMO, it very strongly over-emphasizes the homosexuality of Turing to the detriment of describing his mathematical and technical work and abilities. It's surely no coincidence that Hodges is also gay and that the book was written in an era when homosexuality is not as widely accepted in the mainstream UK as it now is.

YMMV.

Carlos: all my library on BP, Enigma, etc, is in the UK and I can't consult it from here easily to provide suggestions made on it.. A book which I can strongly recommend is [I]The Hut Six Story[/I] by Gordon Welchman. The fact that it is the first one which comes to mind is perhaps an indication of the high regard I have of it.

Thank you Paul. Are you still overseas? Not quite hot enough here, 30 degC, but Thursday will have 37 degC.

[QUOTE=kriesel;512726]Latest check on neighborhood status yielded basically "Great news! Your neighborhood is an approved fiber build and services are estimated to launch in mid 2019." Yay, can't wait! Even though I'm skeptical about the scheduling because there are many other neighborhoods nearby that were approved earlier, it's an encouraging step. I'm definitely looking forward to not needing to drive to town for any appreciable sized download or upload, that times out early on my existing slow unreliable DSL that's been climbing in cost while declining in performance.[/QUOTE]For a while, it was supposed to come in June. Then just "2019". Just got the voicemail call that fiber will get run under my grass in 10 days!

Cool. Has anyone positively identified a case of finding two or more factors in the same class of the same bit level and exponent? It's a low probability for one run, but a substantial probability for millions of exponent & bit level runs.

Going home tomorrow after a week in Reno (work related).

My observatory is working again after a ~2 month hiatus caused by the camera dying. First light was tonight and although no useful scientific data was taken I do have a nice image of a beautiful barred spiral galaxy called [URL="https://telescopius.com/deep-sky/object/11805/ic-1296/galaxy"]IC 1296[/URL].

Still a few niggles to be worked out but I'm a happy bunny again.

Congrats! Always good to hear someone is recording photons again after a break in the action. And a nifty little barred-spiral, too.

I’m again at Bletchley Park, will purchase the book.

The Hut Six Story by Gordon Welchman must be read like an academic book...wow. Think I can do it, it will take some time though.
