Blockchain – Missing Transaction – Bitcoin Stack Exchange

The coin has disappeared from the wallet and never arrived in the wallet.

Although we often say (or write) that coins are kept in wallets, it is important to remember that this is just a convenient shorthand for communication between people.

In reality, Bitcoins do not exist in wallets, they are not stored in wallets and are not moved in or between wallets. Bitcoins do not really move between wallets and are not really sent from one wallet or arrive at another. This is all just hand movement and a very casual analogy.

Also, bitcoins are not stored in the blockchain. In the blockchain, only a list (a journal) of transactions with amounts of money using Bitcoin as a unit of measure is kept.

In summary, everything that is in the blockchain really happened. After about six confirmations, the blockchain is unlikely to change its view. If another person's wallet does not match the general and established view of the blockchain, the wallet is incorrect. Maybe because the wallet is out of sync. Theoretically, the receive address may have been entered incorrectly – but this is relatively unlikely.

Let's say you went into a shop and took a $ 20 bill out of your wallet and handed it to the shopkeeper, who put it in his wallet. Then the shopkeeper denies receipt of your $ 20. What do you do then? If you are lucky, there is a witness. The witness can not resolve your dispute, you must take him to court and ask the witness for testimony.

The blockchain is just your witness. The blockchain can provide evidence, but can not resolve disputes.

The transaction is still missing.

If it is in the blockchain, it is not missing.

If it's not in the blockchain, you still have the money.

Your transaction is in the blockchain and has 328 confirmations at the time of writing. 6 confirmations are usually considered safe. It is as safe as it gets. It definitely is not missing. The wait will not make it much more concrete, visible or undeniable. There is no chance it will disappear (on the brink of an unprecedented catastrophe and the possible end of the Bitcoin world)

Hotels – Booking.com Prepaid – Travel Stack Exchange

I recently booked through Booking.com an apartment in Budapest, which was free.

After reserving the apartment, I received an e-mail from the host of the apartment asking for an upfront payment of 50% of the total cost. The other half must be paid on arrival.

The host asked me to transfer this money.

Is that legitimate? Is that common? It seems a bit strange to me.

Combinatorics – Combinatorial Totals – Mathematics Stack Exchange


$ n choose 0 $+$ n choose $ 4+$ n choose $ 8+ …

The solution to this exercise:

let S1 =$ n choose 0 $$ n choose $ 2+$ n choose4 $$ n choose8 $+ …, S2 =$ n choose1 $$ n choose3 $+$ n choose5 $-…, S3 =$ n choose0 $+$ n choose4 $+$ n choose8 $+ …, S4 =$ n choose2 $+$ n choose6 $+$ n choose10 $+ … and we think (1 + i)$ ^ n $= S1 + iS2 =$ sqrt2 $$ ^ n $(cos$ frac {n pi} {4} $+ isin$ frac {n pi} {4} $) and 2$ ^ {n-1} $+ S1 = 2S3

The problem is that I did not get the part with (1 + i)$ ^ n $I've seen more exercises like these with combinatorial sums, the solution of which was complex numbers, and I'd like someone to explain that method to me. Thank you!

Is this blur normal? – Exchange of photo stacks

Since I have my Canon EOS 760D, I have the feeling that my pictures are not as sharp as on my Nikon 1 V1.
I had not used my 760D for a long time, but on the last photos I felt it was worse than before, for example:
Enter image description here

Zoomed a bit:
Enter image description here

For me it is as if the blurred parts have a kind of blossom, it even seems as if some parts are "doubled" (edges).

I use one Canon EF-S 18-135mm f / 3.5-5.6 IS STM Lens, I do not know if that's normal (low lens quality?) Or if something is wrong with the lens.

What do you think?

Many Thanks

Set Associative Cache Exercise – Computer Science Stack Exchange

I am new to the cache and trying to figure out how to solve this problem. Can someone please provide me some materials to help me solve these kinds of questions? I've tried googling Set Associative Cache, but I have not found many sources on the subject.

Can someone guide me how to solve this question?

2 Set the associative cache

Accept the following contents of a cache in which all blocks are valid. The two-way cache (m = 2) is byte-oriented with a block size of 16 bytes.

Determine the contents of the 8-bit data bus if the processor is reading and the value B70A appears on the 16-bit address bus. If the requested data is not in the cache memory, swipe any previous data in this memory that will be overwritten when new values ​​are saved.

In this case, write the letter on the data bus and set new values ​​for LRU and KEY.
(Note: Numbering of the data columns: 0 … left column, 1 … right column.)

Needed information:

  • Data Content:
  • New value of the LRU:
  • New value of the LRU in raw no:
  • New value of Key:
  • New value of key in column no.:
