The original Colossus had 1,500 valves; the Mk II had 2,500. Contrary to popular belief, these were very reliable provided that you didn't power them up and down all the time; consequently, the Colossi at Bletchley Park were switched on and then not switched off until the end of the war!

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

charismathics exhibits at Infosecurity Europe, London, UK - 19-21 April 2011
charismathics is a global leader in identity management software. Its premier product, the charismathics Smart Security Interface (CSSI), makes it cost-effective and easy for enterprises to integrate multiple authentication solutions into a single, transparent interface. Since 2003, charismathics has pioneered the field of Public Key Infrastructure (PKI), introducing the first PKI client to support Trusted Platform Modules (TPM) and the first PKI client to be fully integrated with pre-boot environments. charismathics also bundles its premier solution with silicon based hardware devices, primarily smart cards and USB cryptographic tokens, where physical and logical security needs also meet when contactless chips and RFID tags are embedded. charismathics is partnering with a growing number of world key players in the field of single sign on, hard disk encryption, digital certificate issuance. Envisioning a revolution in mobile Internet devices, charismathics has turned to this technology as well releasing iEnigma, a software which secures handheld units such as the iPhone, the iPod Touch and most phones featuring Windows Mobile, and provides streamlined two-factor authentication for the enterprise. charismathics offers its security products and services in a variety of industries including building security, banking and finance, healthcare, telecommunications, government and computer manufacturing.

Rewire festival 2015
Korzo, Den Haag
Artist, graduate of Frankfurt’s famed Städelschule, and “experimental computer musician” formerly known as Cracksmurf, Lars Holdhus’s work as TCF explores themes of code, cryptography and privacy. To do this he creates a dizzying, often inspiring mash of visual, sonic, built and written concepts. Boomkat raved about his recent release, 415C47197F78E8… on Liberation Technologies: “Ultimately, words fall well short of adequately describing this stuff; it simply needs to be experienced, fully immersed… pupils dilated.”
This is a rare four rotor Naval Enigma machine that was recovered from U-534. The box on the right holds the spare interchangable rotors
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.

The title of this artwork is 9C1A66DEBEEA8219C72C359BFABA4E0D62F9D36E29542EF5507BEC4961B74248. This series of text and numbers was generated by the SHA-256 cryptographic hash function. It's up to you to decode this hash and find the original text.
It's impossible to reverse engineer a SHA-256 hash. Enter your guesses into a SHA-256 hash generator and see if your hash matches this artwork.
Bitcoin mining uses the SHA-256 as the Proof of work algorithm. Each bitcoin block is identified by a unique SHA-256 hash.
This artwork is identified by its unique hash, which is created from its original identity. Decode the hash, and you'll decode the original title.
