The drawing room at Bletchely Park hosts an exhibition about Gordon Welchman
Welchamn , a mathematician and lecturer at the University of Cambridge, was selected as a potential codebreaker before the war began. Despite only having had a short course in cryptography before starting work at Bletchley Park . His contributions to breaking the Enigma codes included adapting Alan Turing’s design for the codebreaking Bombe machine, changing it into a workable machine. He also established Hut 6, leading the team who decrypted more than 1 million German air force and army codes.

Pictures taken on a visit to Bletchley Park
Bletchley Park was the central site for Britain's codebreakers during World War Two. Run by the Government Code and Cypher School (GC&CS), it regularly penetrated the secret communications of the Axis Powers – most importantly the German Enigma and Lorenz ciphers. The official historian of World War II British Intelligence has written that the "Ultra" intelligence produced at Bletchley shortened the war by two to four years, and that without it the outcome of the war would have been uncertain
Apparently this is what the Internet looks like...

Bletchley Park in Buckinghamshire, was long the top secret centre for government intelligence. Its radio interception was decisive in the fight against Hitler in the Second World War.
This is the hut where Alan Turing and his team worked on their decoding and design work. Most workers at Bletchley were women.

I was in the RAF from Nov 1993 to Dec 2000. These pictures are from my trade training days at RAF Locking near Weston-Super-Mare, 9 Feb 1994 - 1 Aug 1994. I was on course TCO 114.
At RAF Locking I was trained as a Telecommunications Operator (TCO). A TCO mainly worked in Communication Centres or Signals Unit's, operating a variety of telegraphic, cryptographic, radio, and Morse equipment. TCO's were also trained as Telephonists where they worked in station telephone exchanges. TCO's could also serve in a field comms role at Tactical Communications Wing (TCW) RAF Brize Norton, a role in which I served in early 1998.
I later returned to RAF Locking in 1997 to undertake my Morse course (3 Mar 1997 - 10 Jun 1997); I was on QMC 41.
The operational units I served at were:
RAF Waddington
TCW, RAF Brize Norton (detached to Bahrain)
RAF Coningsby

Arlington Hall began as a junior college and high school in 1927 providing genteel education for young ladies. Set in an attractive park-like environment with easy access to Washington, the school boasted indoor and outdoor riding areas and a noted equestrienne club. The school was forced to close in 1942 when the U.S. Government took possession of the property which it used for its most secret cryptographic activities. It is currently the home of the State Department's National Foreign Affairs Training Center, as well as an Army National Guard office complex. R03-0070

The Enigma machines were a series of electro-mechanical rotor cipher machines developed and used in the early- to mid-twentieth century to protect commercial, diplomatic and military communication. Enigma was invented by the German engineer Arthur Scherbius at the end of World War
To avoid merely implementing a simple (and easily breakable) substitution cipher, every key press caused one or more rotors to step by one twenty-sixth of a full rotation, before the electrical connections were made. This changed the substitution alphabet used for encryption, ensuring that the cryptographic substitution was different at each new rotor position, producing a more formidable polyalphabetic substitution cipher. The stepping mechanism varied slightly from model to model. The right-hand rotor stepped once with each keystroke, and other rotors stepped less frequently.

I knabbed this little guy for a special sale price from ncix.com (they normally go for around $22 or so. I'll probably be grabbing a decent usb webcam to use this little ball of light to generate cryptographically secure random numbers. Why? Because I can, and I've got some time on my hands to play with that sorta ultra-geeky (well, ok nerdy) stuff.

STEM stoked for summer…Naval Hospital Bremerton, in conjunction with a partner program between U.S. Naval Undersea Museum, Puget Sound Navy Museum, and Science. Technology, Engineering and Mathematics (STEM) education coordinators at various local commands, distributed STEM-based activity kits to staff members for their children, July 1, 2021. The science kits – each with a colorful lesson page and requisite materials to complete the activity - are primarily suitable for elementary and middle school students. Made available, at no cost, covering a wide range of interests were kits including cryptography, signal flags, polyhedral construction, cribbage and plane spotting; knot tying, chromatography, Cartesian divers and clinometers. Hospital Corpsman 2nd Class (Fleet Marine Force qualified) Fernando A. Perezcarvajal coordinated the command effort. The Navy STEM program supports the Department of the Navy and Marine Corps education and outreach program, providing focus to ‘inspire, engage, and educate the next generation of scientists and engineers, technology and medical professionals. STEM development begins with a outreach programs much like this at the pre-K through 12th grade levels, can continue on through undergraduate and graduate school and also support student advancement into post-doctoral work and all stages of a chosen STEM profession (Official Navy photo by Douglas H Stutz, NHB/NMRTC Bremerton public affairs officer).
Dr. Barry Sanders (right), director of the University of Calgary's Institute for Quantum Information Science, explains the amazing world of quantum computing and quantum cryptography, during the November 12 lecture in the "Genius Speaker Series" of Friday night science talks featuring top researchers from the fields of biology and physics, complementing the Darwin and Einstein exhibits.
Raymond Laflamme's talk failed where so many others have failed before... providing me with a graspable crash-course on quantum computing. Nevertheless, the sheer intensity of the quantum computing wave coming down the continental shelf towards us can be made out from vibrations alone... I don't need a walkthrough to grasp the desired arc of the technology's development.... whether into cryptography, quantum queries, or the very nature of ourselves and the universe.

Quadratic Voting (QV) aims to bring the efficiency of markets to collective decision making by pricing rather than rationing votes. The proposal has attracted substantial interest and controversy in economics, law, philosophy and beyond. The goal of this conference is to evaluate the promise of Quadratic Voting and to stimulate research on QV from a broad range of perspectives. Leading scholars from disciplines ranging from classics to cryptography will present their work on diverse issues related to QV, including the history of the ideas behind it, practical implementation for market research surveys, objections to the use of money in politics and how QV might have averted political disasters in history. The conference papers will be published in a special issue of Public Choice in 2017, following up on a parallel special issue forty years prior on the use of the Vickrey-Clarke-Groves mechanism for collective decisions.
For instance, in the video Tacit:Blue (Rosa Menkman, video, 2015) small interruptions in an otherwise smooth blue video document a conversation between two cryptography technologies; a Masonic Pigpen or Freemasons cipher (a basic, archaic, and geometric simple substitution cipher) and the cryptographic technology DCT (Rosa Menkman, Discrete Cosine Transform encryption, 2015). The sound and light that make up the blue surface are generated by transcoding the same electric signals using different components; what you see is what you hear.
The technology responsible for the audiovisual piece is the NovaDrone (Pete Edwards/Casper Electronics, 2012), a small AV synthesizer designed by Casper Electronics. In essence, the NovaDrone is a noise machine with a flickering military RGB LED on top. The synthesizer is easy to play with; it offers three channels of sound and light (RGB) and the board has twelve potentiometers and ten switches to control the six oscillators routed through a 1/4-inch sound output, with which you can create densely textured drones, or in the case of Tacit:Blue, a rather monotonous, single AV color / frequency distortion.
The video images have been created using the more exciting functions of the NovaDrone. Placing the active camera of an iPhone against the LED on top of the NovaDrone, which turns the screen of the phone into a wild mess of disjointed colors, revealing the NovaDrone’s hidden second practical usage as a light synthesizer.
In this process the NovaDrone exploits the iPhone’s CMOS (Complimentary Metal-Oxide-Semiconductor) image sensor, a technology that is part of most commercial cameras, and is responsible for the transcoding of captured light into image data. When the camera function on the phone is activated, the CMOS moves down the sensor capturing pixel values one row at a time. However because the flicker frequency of the military RGB LED is changed by the user and higher than the writing speed of the phone’s CMOS, the iPhone camera is unable to synch up with the LED. What appears on the screen of the iPhone is an interpretation of its input, riddled with aliasing known as rolling shutter artifact; a resolution dispute between the CMOS and the RGB LED. Technology and its inherent resolutions are never neutral; every time a new way of seeing is created, a new prehistory is being written.
