Lowercase E is unusual in the text. Is it a special teletype font?

An interesting quirk in Ethereum is that a contract address is determined by deployer address + nonce. So, you can send ETH to a contract that does not exist, then later deploy a contract there and recover it.
It is also the same address on many forks of Ethereum, which has led to some strange circumstances when Optimism sent tens of millions of dollars to a smart contract address on the wrong blockchain, and a hacker was able to create a smart contract they controlled using the same address on the blockchain it was accidentally sent to and steal the funds.
Bug or feature. Could it have been a transfer of funds organized to look like a hack?

I visited Bletchley Park museum this summer when in London. Can recommend and it's also really easy to get there; just a 50 minute train ride from London Euston station, and 5 minute walk to the museum. Entire family enjoyed the museum (have two teenage kids). There is also the "National Museum of Computing" located next to it which contains the Bombe, Collosus and related equipment. As I understand it most (or all?)…
A personal Bletchley Park anecdote: my grandfather, an electrical engineer, staffed a radio listening station during the war, and every evening a motorcycle dispatch rider would take the day’s intercepts away to a secret location. It was more than 20 years before my grandfather figured out they went to Bletchley. In the 1980s the Bletchley museum project put out a call for wartime electrical components so they could…
At the end of 90-s some parts sent to the Russian Mir space station were found and bought at flea market - these parts had been pinched from work and their production ceased during those years of collapse in USSR/Russia.

#94ETA: Note that I appear to have been mistaken about the connection to ENIAC. Note that it is equally dangerous to send paraphrased messages using the same key (which is called sending messages "in depth"). This was used to crack the Lorenz ("Tunny") cipher. Interestingly Bletchley Park hadn't gotten their hands on a Lorenz machine, they cracked it based on speculation. And it lead to the development of the first tube…
As I point out now and then, Colossus was not a computer. It was a key-tester, like a Bitcoin miner. Here's the block diagram of Colossus.[1] Before there were general-purpose stored program digital computers, there were many special-purpose computing devices. They checked some, but not all, of those boxes. - IBM had electronic arithmetic in test before WWII, but that went on hold during the war. Mechanical arithmeti…
"Colossus was not a computer. It was a key-tester,"
The original definition of computer was basically a person wot computes (analyzes data and performs arithmetic and so on). That would have mostly involved pencil and paper, fag packets and napkins. IT co-opted the term for their devices, many years later.
What is your issue with Colossus performing automated computations/analysis given some inputs of some sort and hence being described as a computer?
One of the earliest modern day IT related truisms is "garbage in/garbage out" - that dates back to at least getting the clipper out on the cards. Can that notion be applied to Colossus or rather is Colossus the sort of device that gi/go might refer to?
What exactly is a computer?

Oh that’s delightful! I love how contingent these things can be.

Those parts really belong in a museum somewhere because they are an important part of history, irrespective of politics.
What happened to them?

This is the first I’ve heard of Colossus influencing the ENIAC. I was under the impression that Colossus was so secret that ENIAC was designed independently and (falsely) touted as the first tube computer prior to Colossus’ existence being declassified. I’m not sure if I’m misremembering that though.
The ENIAC seems to be the first general purpose electronic digital computer. It wasn't stored program, though - no good memory devices. Plugboards and lots of rotary switches. Took hours to load a new program. Unrelated to Colossus. The first machine to have it all was the Manchester Baby.[1] Now this really was sort of a descendant of Colossus, with some of the same people involved. It was mostly a test rig for the…
Any good books to recommend on computer history?
