The attempt to make DES more secure resulted in the development of Triple DES.

In the 1990s, it was becoming clear that the 56-bit key length of DES was no longer sufficient to protect sensitive data from advanced attacks. In response, the National Institute of Standards and Technology (NIST) launched an effort to develop a successor to DES. This effort resulted in the selection of the Rijndael cipher as the Advanced Encryption Standard (AES) in 2001.

However, in the interim period, there was a need for a more secure version of DES that could be used until AES was widely adopted. This led to the development of Triple DES (3DES), which involves applying the DES algorithm three times with two or three different keys. This effectively increases the key length to 112 or 168 bits, making it much more resistant to brute-force attacks.

While 3DES has been widely used for many years, it is now considered less secure than modern ciphers like AES. In fact, NIST has recommended that organizations phase out the use of 3DES in favor of stronger algorithms.

a. An exponential propagation model is plausible for Bitcoin because the network is designed to propagate information in a peer-to-peer fashion.
b. The probability of at least one stale block being found with α(t)=2 t/30 -1 and tmax=30 seconds is 0.0069.

a. The Bitcoin network is designed to propagate information in a peer-to-peer fashion, which means that each node in the network shares information with its neighbors. As new nodes join the network, they receive information from their neighbors, allowing the information to spread exponentially. The derivative of an exponential function is another exponential function, which supports the plausibility of an exponential propagation model.
b. Using the given α(t) function, we can calculate the proportion of miners who have heard about a new block at any given time. The probability of at least one stale block being found is 0.0069, calculated using the formula P(stale block) = 1 - e^(-λα(tmax)).
c. Lowering β to 60 seconds would decrease the mean time to find a block, which would make transactions post faster. However, this would increase the probability of stale blocks being found because the window of time for a new block to propagate through the network would be smaller. This could cause problems for the network because stale blocks can lead to wasted mining efforts and potential double-spending attacks.

Schema decomposition is a process in which a given table is divided into multiple tables in order to achieve a higher level of normalization, specifically Boyce-Codd Normal Form (BCNF). To decompose the given table (Order) into BCNF, we need to analyze the functional dependencies provided.

The given functional dependencies are:
1. CustID -> Name, Address, State, Zip
2. BookID -> Title, Author, Price, Category
3. OrderID -> CustID, BookID, ShipDate

Based on these dependencies, we can decompose the Order table into three separate tables to conform to BCNF:

1. Customer (CustID, Name, Address, State, Zip)
2. Book (BookID, Title, Author, Price, Category)
3. OrderInfo (OrderID, ShipDate, CustID, BookID)

1. Customer table: This table stores information about customers, including their unique CustID, Name, Address, State, and Zip. CustID is the primary key for this table as it functionally determines the other attributes.

2. Book table: This table contains details about the books, including BookID, Title, Author, Price, and Category. BookID is the primary key since it uniquely identifies each book and functionally determines the other attributes.

3. OrderInfo table: This table holds information about the orders, including OrderID, ShipDate, CustID, and BookID. OrderID is the primary key because it uniquely identifies each order. CustID and BookID are foreign keys referring to the Customer and Book tables, respectively.

If you enter only one value for border-radius properly, that radius is applied to all four corners of the element. This is because when a single value is given for border-radius, it is assumed that the same value applies to all four corners of the element.

Border-radius is a CSS property that allows you to round the corners of an element. It takes one or more values as input, which can be specified in different ways such as percentages, pixels, or ems. When using a single value for border-radius, it is important to note that the value is applied to all corners of the element equally. This means that all four corners will have the same radius, resulting in a symmetrical shape.

However, if you want to specify different radius values for each corner, you can use the shorthand syntax for border-radius. This syntax allows you to specify four values, which represent the top-left, top-right, bottom-right, and bottom-left corners of the element, respectively.

A linked list is a data structure that consists of a sequence of nodes, where each node contains a value and a pointer to the next node in the sequence. Overall, the printlinkedlist() function is a simple and elegant way to print the values of a linked list recursively.

To write a recursive function called printlinkedlist() that outputs the integer value of each node in a linked list, we need to first define the structure of the linked list. Let's assume that the linked list is represented by a class called Node, which has two attributes: a value and a next pointer. The next pointer is None for the last node in the list.

Here's one way to implement the printlinkedlist() function recursively:

```python
class Node:
   def __init__(self, value, next=None):
       self.value = value
       self.next = next

def printlinkedlist(node):
   if node is not None:
       print(node.value)
       printlinkedlist(node.next)
```

Let's go through this code step by step. The printlinkedlist() function takes a node as an argument, which represents the current node in the linked list that we want to print. The first thing we do in the function is to check if the node is not None. If it is None, then we have reached the end of the linked list, so we don't need to print anything.

If the node is not None, we print the value of the current node using the print() function. Then we call the printlinkedlist() function recursively with the next node in the linked list as the argument. This will print the value of the next node, and so on, until we reach the end of the linked list.

Note that the printlinkedlist() function is a tail-recursive function, which means that the recursive call is the last operation performed in the function. This is important because tail recursion can be optimized by some compilers and interpreters, which can result in better performance.
