English proficiency tests IELTS, TOEFL: Reading these books can help you crack the exam

 Books can help in more ways than one. For example, they can take your vocabulary to the next level

Books can be our best friends, it's not for nothing that this saying is popular. Here are a few classics and what they can teach you when it comes to English language 

Lord of the Flies

BY William Golding

Often prescribed as curriculum in school, this book is a modern novel using descriptive and dramatic language that helps a reader visualise the story

Animal Farm

BY George Orwell

Simple language drives this novel. This story is short and effective, giving the reader an understanding on how to use language in a clever way

To Sir, With Love

BY ER Braithwaite

The story is about how a professor wins over the hearts of unruly students. The words and characterisation will surely teach you a thing or two too

The Curious Incident of the Dog in the Night-Time

BY Mark Haddon

A heart-warming tale of an autistic kid and a dog who set out to solve a murder mystery. The perspective of the world that the kid, Christopher, has is charming

The Old Man and the Sea

BY Ernest Hemingway

Written by journalist Ernest Hemingway, the book has language that is clear, straight forward and factually tight. The sentence structure is short, making it easy to follow

send XML data


If you want to send XML data to another service internally, you can use a variety of communication methods depending on your system architecture and the technologies you are working with. Here are some common approaches:

  1. HTTP/HTTPS Requests:

    • Description: You can send XML data to another service internally using HTTP or HTTPS requests.
    • How: Use a library in your programming language of choice to make HTTP requests. Include the XML data as the request body.
    • Example: In Python, you might use the requests library to send a POST request with an XML payload.
      python
      import requests url = "http://internal-service/api/endpoint" headers = {"Content-Type": "application/xml"} xml_data = """ <book> <title>The Great Gatsby</title> <author>F. Scott Fitzgerald</author> <year>1925</year> <genre>Fiction</genre> </book> """ response = requests.post(url, data=xml_data, headers=headers) print(response.status_code) print(response.text)
  2. Message Queues:

    • Description: You can use a message queue to send XML data as messages to another service.
    • How: Send XML data as messages to the queue, and the other service can consume the messages from the queue.
    • Example: In Python, you might use the pika library to interact with RabbitMQ and send XML data as messages.
      python
      import pika connection = pika.BlockingConnection(pika.ConnectionParameters('localhost')) channel = connection.channel() channel.queue_declare(queue='book_queue') xml_data = """ <book> <title>The Great Gatsby</title> <author>F. Scott Fitzgerald</author> <year>1925</year> <genre>Fiction</genre> </book> """ channel.basic_publish(exchange='', routing_key='book_queue', body=xml_data) connection.close()
  3. Remote Procedure Call (RPC):

    • Description: You can use RPC mechanisms to send XML data to another service internally.
    • How: Use an RPC library or framework to make a call to the remote service, passing XML data as an argument.
    • Example: In gRPC, you might define a service method that accepts XML data as input.
  4. Inter-Process Communication (IPC):

    • Description: You can use IPC mechanisms to send XML data between different processes.
    • How: Use methods such as sockets, shared memory, or named pipes to communicate and pass XML data.
    • Example: In Python, you might use a socket connection to send XML data to another process.

Why does C++ allow unsafe code?


That is, why does C++ support operations that can be used to violate the rules of static (compile-time) type safety?
  • to access hardware directly (e.g. to treat an integer as a pointer to (address of) a device register)
  • to achieve optimal run-time and space performance (e.g. unchecked access to elements of an array and unchecked access to an object through a pointer)
  • to be compatible with C
That said, it is a good idea to avoid unsafe code like the plague whenever you don't actually need one of those three features:
  • don't use casts
  • keep arrays out of interfaces (hide them in the innards of high-performance functions and classes where they are needed and write the rest of the program using proper strings, vectors, etc.)
  • avoid void* (keep them inside low-level functions and data structures if you really need them and present type safe interfaces, usually templates, to your users)
  • avoid unions
  • if you have any doubts about the validity of a pointer, use a smart pointer instead,
  • don't use "naked" news and deletes (use containers, resource handles, etc., instead)
  • don't use ...-style variadic functions ("printf style")
  • Avoid macros excpt for include guards
Almost all C++ code can follow these simple rules. Please don't be confused by the fact that you cannot follow these rules if you write C code or C-style code in C++.

For an ambitious project to make C++ easier to use and safer without damaging its efficiency or flexibility, see the Core C++ Guidelines.
