On August 1, 2023, the free tier for the Amazon Simple Email Service (SES) will change. We are adding more features to the SES free tier: it now includes more outbound email message sources, SES’ new Virtual Deliverability Manager, and a higher limit for receiving inbound messages. We are also lowering the free tier limit for outbound messages and reducing the duration of the SES free tier to 12 months.

This may affect your bill starting in August 2023. Since you are already using SES, you will be able to take advantage of the revised free tier for another 12 months (until August 2024). Based on your SES usage in May 2023, this change would not have affected your SES bill. Note this is an estimate based on your usage, and actual billing impact may vary depending on your usage patterns each month and any discounts you may have.

The revised SES free tier offers you more flexibility. Previously, the SES free tier included up 1,000 inbound email messages per month and up to 62,000 outbou

In this tutorial, we will walk through the process of using the grep command to filter Nginx logs based on a given time range. grep is a powerful command-line tool for searching and filtering text patterns in files.

Step 1: Access the Nginx Log Files First, access the server or machine where Nginx is running. Locate the log files that you want to search. Typically, Nginx log files are located in the /var/log/nginx/ directory. The main log file is usually named access.log. You may have additional log files for different purposes, such as error logging.

Step 2: Understanding Nginx Log Format To effectively search through Nginx logs, it is essential to understand the log format. By default, Nginx uses the combined log format, which consists of several fields, including the timestamp. The timestamp format varies depending on your Nginx configuration but is usually in the following format: `[day/month/year:hour:minute

On Thursday (June 22), former US President Barack Obama courted controversy by virtue-signalling India about its ‘human rights’ record.

Obama, who has a notorious record as a potential war criminal, suggested that the Indian Prime Minister must be told by the Biden administration about protecting the ‘Muslim minority in a majority Hindu India.’ He also hinted at another ‘partition’ if India, under the Modi government, did not mend its ways.

The former US President made the contentious remarks during an interview with CNN news host Christiane Amanpour, just hours before PM Modi made his historic address at the joint session of the US Congress.

Running Commands in Parallel in Linux

In Linux, you can execute multiple commands simultaneously by running them in parallel. This can help improve the overall execution time and efficiency of your tasks. In this tutorial, we will explore different methods to run commands in parallel in a Linux environment.

Method 1: Using & (ampersand) symbol

The simplest way to run commands in parallel is by appending the & symbol at the end of each command. Here's how you can do it:

 bash

    
command_1 & command_2 & command_3 &

  

This syntax allows each command to run in the background, enabling parallel execution. The shell will immediately return the command prompt, and the commands will execute concurrently.

For example, to compress three different files in parallel using the gzip command:

 bash

    
gzip file1.txt & gzip file2.txt & gzip file3.txt &

  

Method 2: Using xargs with -P

Introduction to Upanishads

The Upanishads are a collection of ancient philosophical and spiritual texts that form the core teachings of Hinduism. These texts are considered the culmination of Vedic knowledge and are revered for their profound insights into the nature of existence, consciousness, and the ultimate reality. The word "Upanishad" is derived from the Sanskrit root words "upa" (near), "ni" (down), and "shad" (to sit), implying the act of sitting close to a spiritual teacher to receive esoteric knowledge.

Significance of the Upanishads

The Upanishads occupy a central position in Hindu philosophy and have influenced various schools of thought, including Vedanta, Yoga, and Buddhism. These texts delve into profound metaphysical and spiritual concepts, exploring the nature of the self (Atman), the ultimate reality (Brahman), and the interconnectedness of all things. They offer profound meditations on the nature of existence, the purpose of life, and the path to spiritual l
