So after being critiqued on the first image, here's the second attempt!

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

The blog post Ethereum versus Litecoin vs Bitcoin – A comparison was originally published on Business Law Group

Comparing Bitcoin, Litecoin, and EthereumBelow is a good comparison on the differences between the big three digital currencies – Litecoin, Ethereum and Bitcoin. As a part of our FinTech practice, we are constantly dealing with questions about these different platforms. What we do is help our client navigate the waters that are described in the article. The article is a long, but that is what makes it so good. Be sure to take a gander. For more about us, visit kcbusinesslawgroup.com/Posted by Business Law Group.https://www.mintdice.com/blog/bitcoin-vs-ethereum-vs-litecoinBITCOIN VS. ETHEREUM VS. LITECOINWhile cryptocurrency has only recently become a popular term in finance, it has been around for a long time. Before names like Bitcoin, Ethereum, and Litecoin even existed, there were attempts to create a decentralized currency.David Chaum, a respected cryptographer, launched ECash, an anonymous system in the 1990s but it failed. Chaum built the system on currently existing government financial principles and infrastructure like credit cards. RPOW, BitGold, B-Money were also created but failed.Cryptographers could not get past specific challenges that they faced at the time. The first challenge was how to achieve true decentralization and the second was the issue of double spending. The prevention of double spending meant the use of a third-party clearing house. This wasn’t acceptable because to achieve the type of innovative digital finance they wanted; the system had to be independent of any institution.In 2008, cryptographers finally stumbled on the information they had been searching for when an anonymous contender released the blueprint for a digital currency known as Bitcoin. It showed the technical specifications of the blockchain — a decentralized technology that creates a trustless, permissionless system and eliminates the problem of double spending. This new technology took the world by storm, later leading to changes in the financial industry as well as other industries such as real estate. With the cryptocurrency revolution, came many coins, tokens, and altcoins. Here, we take a deep dive into the similarities and differences between some of the most popular and valued ones: Bitcoin, Ethereum, and Litecoin.BITCOIN EXPLAINEDBitcoin is a digital currency, created as a store of value for the anonymous exchange of goods and services online. It typically has all the properties of a more traditional currency and can be broken down into smaller parts, up to eight decimal places. It’s also the largest cryptocurrency by market capitalization.A BRIEF HISTORY OF BITCOINBitcoin first originated in 2008 when an anonymous programmer under the pseudonym of Satoshi Nakamoto released a paper in a cryptography mailing list. This paper detailed the workings of a new digital currency, built on blockchain technology. The virtual currency was designed to imitate key qualities of traditional money while providing anonymity, transparency and eliminating the need for a third party.Researchers tried to find out the identity of this anonymous programmer, all to no avail. It became a mystery to the cryptography community who could not ignore this act of charity, containing a brilliant solution that had eluded them for so long.The technology behind Bitcoin is open source, […]

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.

Putting resources into the cryptographic money market can be testing, especially for more prepared investors.This is on the grounds that straightforwardly putting resources into digital currencies requires the utilization of original thoughts, instruments, and advances.

You will require an unmistakable comprehension of what to do and what to expect in the event that you choose to take a Crypto Asset Recovery shot at cryptography.

Whether you need to trade Bitcoin, Litecoin, Ethereum, or any of the 1300 tokens, you should choose a Trade that arrangements in the items you need.

The expression "crypto" and "bitcoin" are much of the time utilized conversely in light of the fact that Bitcoin is the most notable decentralized cryptocurrency.However, the truth is that other digital forms of money can likewise be utilized to make crypto-ventures.

Litecoin is an open-source decentralized installment network that works without a go between. It is likewise alluded to as "silver to Bitcoin's gold."

What recognizes Litecoin from Bitcoin?Well, there are numerous similitudes between the two, however Litecoin produces impedes a lot quicker than Bitcoin does.Investors all over the planet are tolerating Litecoin subsequently.

In 2011, Charlie Lee, a previous Google engineer, laid out Litecoin.Despite the way that Litecoin misses the mark on's namelessness innovation, late reports show that Litecoin is liked over Bitcoin because of its persistence.The Bitcoin SegWit innovation, which considers secure money exchanging between peers without the contribution of trades, is one more benefit of Litecoin.

Ethereum is a decentralized programming stage that was delivered in 2015 and makes it workable for dispersed applications and shrewd agreements to work without obstruction from outside parties.The ether, what capabilities as a gas pedal inside the ethereum stage, is the currency.Ethereum is the market chief in cryptocurrencies.is Bitcoin's nearest rival in prominence.

Zcash, which expects to resolve the issue of unknown exchanges, acquired fame close to the furthest limit of 2016.Let's say that "assuming bitcoin is like HTTP for cash, Zcash is HTTPS" to grasp the money.

To keep up with exchange straightforwardness, protection, and security, the money offers the safeguarded exchange option.Investors will actually want to move scrambled information accordingly.

All run, previously known as darkcoin, is a variation of bitcoin that is more selective.Evan Duffield presented it in January 2014 under the name Xcoin.The Decentralized Independent Association, or DAO, is one more name for it.The coin was intended to eliminate Bitcoin's ongoing restrictions.At the occasion, Bitcoin stands firm on a critical foothold among digital currencies.

Cryptographic money is an option in contrast to virtual cash that guarantees mysterious and secure shared transactions.Making the perfect venture at the ideal time is the way to making a ton of money.As a decentralized computerized system, digital currency models capability without a broker rather than the development of standard money.The people group peer network issues, makes due, and underwrites the consistent movement in this conveyed digital money mechanism.Over some other strategy, including computerized wallets and different media, the cryptographic money is eminent for its rapid exchanges.

Monero (XMR) and Bitcoin Money (BCH) are two other famous digital currencies notwithstanding those beforehand mentioned.Ripple and EOS (XRP).

While bitcoin has set the norm and is right now the market chief, other digital currencies have likewise set up a good foundation for themselves and are acquiring notoriety on a day to day basis.Given the pattern, the other digital currencies will be around for quite a while and may before long test Bitcoin's situation.

Associate with "The Top Coins" assuming you have settled on the choice to put hypothetically in this troublesome innovation and wish to get all suggestions, both now and later on.

This is a memorial to the Polish codebreakers Marian Rejewski, Jerzy Różycki, and Henryk Zygalski, who worked on breaking the Enigma code prior to the start of World War II. In 1939, the information they had obtained was shared by Poland with the French and British intelligence services; this contributed significantly to the codebreaking efforts at Bletchley Park.

This memorial was unveiled in 2002; at the same time, two more identical plaques were also unveiled, one at the Polish Embassy in London, and one in Piłsudski Square, Warsaw, on the wall of the building where the three mathematicians worked.

Paranoid Steganography is an intentionally naive approach to interpreting signals and symbols. It combines the techniques of cryptographic analysis and reverse engineering with the premise that there are secret messages everywhere. Workshop participants will build simple antennae to capture ambient electro-magnetic signals. These signals will be fed into a laptop which will then translate them based on our paranoid mapping to sound or images.

Warmer view, showing the duck pond (ducks out of frame), and more of the house, including the castle turret (possibly a water tower) seen at top center.

The tower made a great spot for a radio room when military intelligence took over Bletchley in 1938. This radio was the legendary "Station X." It was moved out of the house when it grew into a major communication station with a large rhombic antenna. Soon after that, it was moved away from Bletchley altogether, to avoid attracting the wrong kind of attention.

It must have worked, because Bletchley was never bombed, despite its being just about the most important intelligence site in the world at the time. Bombs fell at a safe distance down the road, but were probably targeted on the railway station.
