List of AWS
The below are the list of AWS database offerings:
- Amazon Aurora
- It is a type of relational database used for transactional applications.
- Amazon RDS
- It is a type of relational database used for transactional applications.
- Amazon Dynamo DB
- It is a type of non-relational database used for internet scaling applications.
- It is server less NoSQL database.
- Amazon Redshift
- It is a data warehouse used for data analytics.
- Amazon ElastiCache
- It is a type of in-memory data store used in caching the data and process real-time workloads.
- Amazon Neptune
- A Highly connected data can be build using the Graph database.
Difference among the Amazon’s RDS, DynamoDB, ElastiCache and Redshift services:
| Amazon’s RDS | Amazon’s DynamoDB | Amazon’s ElastiCache | Amazon’s Redshift |
| It is a managed Relational database. | It is NoSQL database. | It is an in-memory data store. | It is a data warehouse. |
| Provides service with easy setup. It is easy to operate and could be scaled in the cloud. | It is fast and flexible that provides a NoSQL database service for the application in a consistent and single millisecond latency at required scale. | It could be deployed, operated and scaled effortlessly operated in an open source compatible in memory data store. | It is simple, fast and cost effective fully managed data warehouse to manage the data using the SQL and existing Business Intelligence tools. |
| It is used in OLTP (Online Transaction Processing) systems. | It can be used in the system that requires millisecond read latency at required scale. | It can be used in the system that requires sub- millisecond response time. | It is used for the OLAP(OnLine Analytical Processing) systems. |
| It supports read replicas across regions and gets backup at Amazon S3. | It uses streams to replicate the data to a table and to another table and does not require any backup. | Replicas are provided based on the read scaling and gets backup automatically. | Data gets replicated automatically and gets backup in Amazon S3... |

Clustering by k-means, with preprocessing tokenization, term weighting TFIDF.
Manhattan Distance. Number of cluster is 2. Centroid docID 2 and docID 9.
Change the following code so that there is always at least one way to get from the left corner to the top right, but the labyrinth is still randomized.
The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. Take care that the player and the dragon cannot start off on walls. Also the dragon starts off from a randomly chosen position
public class Labyrinth { private final int size; private final Cell[][] grid;
public Labyrinth(int size) { this.size = size; this.grid = new Cell[size][size]; generateLabyrinth(); }
private void generateLabyrinth() { Random rand = new Random(); for (int i = 0; i < size; i++) { for (int j = 0; j < size; j++) { // Randomly create walls and paths grid[i][j] = new Cell(rand.nextBoolean()); } } // Ensure start and end are…
Change the following code so that it checks the following 3 conditions:
1. there is no space between each cells (imgs)
2. even if it is resized, the components wouldn't disappear
3. The GameGUI JPanel takes all the JFrame space, so that there shouldn't be extra space appearing in the frame other than the game.
Main():
Labyrinth labyrinth = new Labyrinth(10);
Player player = new Player(9, 0); Dragon dragon = new Dragon(9, 9);
JFrame frame = new JFrame("Labyrinth Game"); GameGUI gui = new GameGUI(labyrinth, player, dragon);
frame.add(gui); frame.setSize(600, 600); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true);

- Make the following game user friendly with GUI, with some simple graphics. The GUI should be in another seperate class, with some ImageIcon, and Game class should be added into the pane. The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.

- In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…arrow_forwardHow do you distinguish between hardware and a software problem?
