Enabling Remote Connections to PostgreSQL on Ubuntu

noreply@blogger.com (Unknown) — Fri, 20 Oct 2023 04:33:00 +0000

Enabling remote connections to a PostgreSQL server on Ubuntu 20.04 involves several steps to configure the PostgreSQL server and open up the necessary ports. Additionally, I'll provide information on changing the password for an existing PostgreSQL user if needed.

Step 1: Modify the PostgreSQL Configuration File

Open the PostgreSQL configuration file "postgresql.conf" using a text editor. The file is typically located in the /etc/postgresql/12/main directory. To open the file from the Linux Terminal, execute:

sudo nano /etc/postgresql/12/main/postgresql.conf

Find the line #listen_addresses = 'localhost' and uncomment it by removing the # character at the beginning of the line.

Next, change the value of listen_addresses to "*", allowing PostgreSQL to listen on all available IP addresses. Alternatively, you can specify a specific IP address or a range of IP addresses that are allowed to connect to the server.

Step 2: Modify the pg_hba.conf File

Open the "pg_hba.conf" file using your preferred text editor, typically located in the /etc/postgresql/12/main directory. To open the file from the Linux Terminal, execute:

sudo nano /etc/postgresql/12/main/pg_hba.conf

Find the section that allows local connections and modify it as follows:

# IPv4 local connections:
host    all             all             127.0.0.1/32            md5

Change it to allow connections from any IP address (0.0.0.0/0):

# IPv4 local connections:
host    all             all             0.0.0.0/0            md5

Step 3: Allow Port 5432 Through the Firewall

To enable traffic on port 5432 through the firewall, execute the following command:

sudo ufw allow 5432/tcp

Step 4: Restart PostgreSQL

Restart the PostgreSQL service to apply the changes:

sudo service postgresql restart

Changing the Password for an Existing PostgreSQL User:

If you need to change the password for an existing PostgreSQL user, you can follow these steps:

Log in to the PostgreSQL database as a superuser or a user with administrative privileges. You can do this by using the psql command:

sudo -u postgres psql

Change the password for the user using an SQL command. Replace username with the actual username and new_password with the new password you want to set:

ALTER USER username WITH PASSWORD 'new_password';

Exit the PostgreSQL prompt:

\q

After completing these steps, you should be able to connect to the PostgreSQL server from a remote machine and have successfully changed the password for an existing user. However, please keep in mind that allowing remote access to a PostgreSQL server can pose security risks. Therefore, it's recommended to use strong passwords, encryption, and firewall rules to protect your system.

Managing Linux Processes: A Comprehensive Guide to Viewing and Killing Running Processes

noreply@blogger.com (Unknown) — Tue, 19 Sep 2023 02:48:00 +0000

Introduction:

Linux is a versatile and powerful operating system used in various environments, from servers to desktops. One of its crucial aspects is process management. Knowing how to view and manage running processes is essential for system administrators and regular users alike. In this article, we’ll explore how to check all running processes on Linux and discuss the process of killing them when necessary.

Managing Linux Processes

Viewing Running Processes:
To check all running processes on Linux, you can use the ps command. There are several ways to use ps, but one of the most common and informative methods is:

ps aux

ps: This is the command for displaying information about running processes.
aux: The options "a" and "u" stand for "all users" and "user-oriented output," respectively. This combination provides a detailed list of all processes running on the system.

When you execute this command, you’ll see a table with various columns containing information about each process. Some of the essential columns include:

USER: The owner of the process.
PID: The Process ID, a unique identifier for each process.
%CPU: The percentage of CPU usage by the process.
%MEM: The percentage of RAM (memory) usage by the process.
VSZ: Virtual memory size in kilobytes.
RSS: Resident Set Size, the portion of a process's memory that is held in RAM.

Killing Processes:
Sometimes, you may need to terminate a running process, either because it’s unresponsive or consuming too many system resources. To do this, you can use the kill command. Here's the basic syntax:

sudo kill -9 PID

sudo: This command is used to execute another command with superuser privileges, which are often required to kill processes owned by other users or system services.
kill: The primary command for terminating processes.
-9: This is a signal number (SIGKILL) that forcefully terminates the process. It should be used cautiously, as it doesn't allow the process to clean up after itself, potentially leading to data corruption or other issues.
PID: Replace this with the Process ID of the process you want to kill.

For instance, if you want to terminate a process with a PID of 12345, you’d run:

sudo kill -9 12345

Alternatively, you can use the pkill command to kill processes by their name:

sudo pkill process_name

process_name: Replace this with the name of the process you want to terminate.

Conclusion:
Understanding how to view and manage running processes is a fundamental skill for any Linux user or administrator. The ps aux command provides valuable insights into the processes running on your system, while the kill command allows you to terminate processes when necessary. However, exercise caution when using the -9 option with kill, as it can have unintended consequences. Always ensure that you are terminating the correct process, especially when working with critical system processes.

By mastering process management on Linux, you’ll have better control over your system’s performance and stability, ensuring that it operates smoothly and efficiently.

How to Install Python 3.8 on Ubuntu 16.04

noreply@blogger.com (Unknown) — Thu, 19 Jan 2023 17:40:00 +0000

Installing Python 3.8 on Ubuntu with Apt

Installing Python 3.8 on Ubuntu with apt is a relatively straightforward process and takes only a few minutes:

Run the following commands as root or user with sudo access to update the packages list and install the prerequisites:
```
sudo apt update
sudo apt install software-properties-common
```

Add the deadsnakes PPA to your system’s sources list:

sudo add-apt-repository ppa:deadsnakes/ppa

When prompted press Enter to continue:

Press [ENTER] to continue or Ctrl-c to cancel adding it.

Once the repository is enabled, install Python 3.8 with:
```
sudo apt install python3.8
```
Verify that the installation was successful by typing:
```
python3.8 --version
```
```
Python 3.8.0
```

At this point, Python 3.8 is installed on your Ubuntu system, and you can start using it.

Installing Python 3.8 on Ubuntu from Source

In this section, we’ll explain how to compile Python 3.8 from the source.

Update the packages list and install the packages necessary to build Python:

sudo apt update
sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev

libssl-dev libreadline-dev libffi-dev wget

Download the latest release’s source code from the Python download page using wget:
```
wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz
```

At the time of writing this article, the latest release is 3.8.0.

When the download finishes, extract the gzipped archive:
```
tar -xf Python-3.8.0.tgz
```
Switch to the Python source directory and execute the configure script which performs a number of checks to make sure all of the dependencies on your system are present:
```
cd Python-3.8.0
./configure --enable-optimizations
```

The --enable-optimizations option optimizes the Python binary by running multiple tests. This makes the build process slower.

Start the Python 3.8 build process:
```
make -j 8
```

For faster build time, modify the -j to correspond to the number of cores in your processor. You can find the number by typing nproc.

When the build process is complete, install the Python binaries by typing:
```
sudo make altinstall
```

Do not use the standard make install as it will overwrite the default system python3 binary.

That’s it. Python 3.8 has been installed and ready to be used. Verify it by typing:
```
python3.8 --version
```
The output should show the Python version:
```
Python 3.8.0
```

Feedback

You have installed Python 3.8 on your Ubuntu 16.04 machine, and you can start developing your Python 3 project.

If you have any questions or feedback, feel free to comment below.

If you are unable to get the No Internet page, open a new tab and type chrome://dino, and press enter.

Playing

Space Bar / Up: Jump (also to start the game)
Down: Duck (pterodactyls appear after 450 points)
Alt: Pause
The game enters a black background mode after every multiple of 700 points for the next 100 points.

Open Chrome Console

Make sure you are on the No Internet Connection page.
Right-click anywhere on the page and select Inspect.
Go to the Console tab. This is where we will enter the commands to tweak the game.

Tweaking Speed

Type the following command in Console and press enter. You can use any other speed in place of 1000.

Runner.instance_.setSpeed(1000)

Immortality

After every command press enter. All the commands are case-sensitive.
We store the original game over function in a variable:
```
var original = Runner.prototype.gameOver
```

Then, we make the game over function empty:

Runner.prototype.gameOver = function(){}

Stopping the game after using Immortality

When you want to stop the game, Revert back to the original game over function:

Runner.prototype.gameOver = original

Setting the current score

Let’s set the score to 12345. You can set any other score less than 99999. The current score is reset on the game over.

Runner.instance_.distanceRan = 12345 / Runner.instance_.distanceMeter.config.COEFFICIENT

Dino jumping too high?

You can control how high the dino jumps by using the below function. Adjust the value as necessary.

Runner.instance_.tRex.setJumpVelocity(10)

Solving the Problem of Conditional Statement Optimization in C++

Programming is all about solving problems efficiently and effectively. In the world of competitive programming and software development, writing optimized code is crucial. Let's dive into the provided code snippet and explore how to optimize the conditional statement for better performance.

Understanding the Problem

The given code snippet is written in C++ and aims to solve a particular problem using conditional statements. Let's break down the problem statement and the code's logic:

The code takes an integer t as input, representing the number of test cases.
For each test case, three integers n, x, and y are input.
The goal is to determine whether the expression (n+1)*y >= x holds true or not.

If the expression is true, the code prints "Yes", otherwise, it prints "No".

Analyzing the Code

The provided code is functional and correctly solves the problem. However, there is an opportunity for optimization in the conditional statement.

The original conditional statement:

if ((n+1)*y >= x)

This statement calculates (n+1)*y every time it's evaluated. Since the value of (n+1)*y remains constant within each test case, it's unnecessary to compute it repeatedly.

Optimizing the Code

We can optimize the code by calculating (n+1)*y once and storing it in a variable before the conditional statement. This way, the calculation is performed only once for each test case, improving the code's efficiency.

Here's the optimized version of the code:

#include <iostream>
using namespace std;

int main() {
    int t;
    cin >> t;
    while (t--) {
        int n, x, y;
        cin >> n >> x >> y;

        int product = (n + 1) * y;  // Calculate (n+1)*y only once

        if (product >= x) {
            cout << "Yes" << endl;
        } else {
            cout << "No" << endl;
        }
    }
    return 0;
}

Benefits of Optimization

Optimizing the conditional statement by precomputing the constant value (n+1)*y provides several benefits:

Improved Performance: By performing the calculation only once, the code becomes more efficient, especially when dealing with a large number of test cases.
Reduced Redundancy: Unnecessary repeated calculations are eliminated, making the code easier to understand and maintain.
Faster Execution: Since the calculation is performed only once per test case, the code execution is faster, which is crucial for competitive programming tasks.

Conclusion

Optimizing code is a valuable skill that can lead to better performance and efficiency in programming tasks. By identifying and eliminating redundant calculations, we can make our programs run faster and more smoothly. In the provided code snippet, optimizing the conditional statement by calculating (n+1)*y once greatly enhances the efficiency of the program while maintaining its correctness.

Covid-19(Coronavirus Disease)

noreply@blogger.com (Unknown) — Wed, 14 Oct 2020 00:00:00 +0000

Coronavirus Disease: This diseases changed our daily life in 2020. First of all, this virus spread in China late December 2019. Then the virus was spread all over the world. Many people has been died by attacking the virus. After few months later covid-19 came to Bangladesh in March 2020. After coming the virus to our country all people of Bangladesh were afraid. I'm also afraid because the covid-19 is different from others. Main reason is anyone can't see this virus.

Covid changed our lifestyle: This coronavirus disease was changed our lifestyle. In this time, we did not do anything for caring our life. Some people of Bangladesh was carried poor life. And they couldn't eat properly. Because their income source has been stopped by this pendamic setuations. All poor income people depends on relief.

Preventive healthcare: All countries government were arranged and managed ther health care system quickly. Because covid-19 attacked and damaged people body very quickly. Basically, old peoples were dangerous position (Doctors said). But I think that the covid could attack all classes people. And the virus wasn't strong to hard-working people. Because those people has fighting energy on their body. For this reason, they were able to get rid from covid-19.

Died people by covid: The number of died people in this world by covid-19 was very much. I don't want to mention the number of died people, because it was changeable all over the day.

How to overcome negative thoughts in mind

noreply@blogger.com (Unknown) — Wed, 12 Aug 2020 09:16:00 +0000

You have wrong thoughts in your mind. After reading this article, I hope that you would be able to learn how to overcome from negative thoughts in mind. So please read this article using your full attention.

We often start comparing a person from a distance. I would say it's not right at all. Because the way we think about others is like he is younger than me, he is shorter than me, he is longer than me, he is idle than me, he is slower than me, he is faster than me etc. That's not right. Other people may be better or worse than you. But you don't understand him well and start comparing him. For this reason, negative thoughts come in mind. It’s not right for you. Because all over the world has different types of people. They may be smaller or bigger than you, but try to learn from them, not compare. If you can remember these things, you must be good, you can do something good.

On earth we are all completely different from each other

noreply@blogger.com (Unknown) — Wed, 03 Jun 2020 10:13:00 +0000

Best Motivational Speech:

Congenitally or hereditarily, we blame ourselves in many ways. As we say, why was born in a poor house ?, I can not do anything in life! Why wasn't Bill Gates born into the family? Why not Mark Zuckerberg's family? Why am I not the son of a millionaire? Why don't I have a house or a car? By thinking these things, we weaken ourselves. "How to be successful!" To get out of this thought and succeed, I am sharing a story with you: -

One was a crow. He was not satisfied with her life. He used to compare himself with everyone. One day I saw a cuckoo and thought to myself that the cuckoo is black like me but people love him for his beautiful voice. Seeing this, the crow came to the creator and said, "Why did you give me such a voice?" Which is unpleasant to people. When he saw me, he drove me away. But how much the cuckoo gets caressed! Then the creator said, you want to live as a cuckoo. The crow said, yes I want to live as a cuckoo. Then the creator made him a cuckoo. Before long, a hunter was busy trying to catch him. Fearing this, he flew away. As he flew, he saw people feeding the chickens and building houses for them. Seeing this, the crow went back to the creator. He went and said to the creator, why didn't you give me the life of a chicken. How beautiful their life is, people care for them, hunters do not come to catch them. So I decided that what I really needed to do was learn how to do it right. The Creator gave the crow the life of a chicken. Then life as a crow's chicken was going well. But he was sad to see the pigeons, because the pigeons can fly but they can't fly. One day while walking, he noticed that a man had caught and slaughtered one of his chickens. Seeing this, the crow went back to the creator, saying I don't want to live as a chicken. The Creator said to the crow, What do you want to live as? The crow said, I want to live as a pigeon. The Creator gave the crow the life of a dove. The crow is very happy with the life of the pigeon. But this happiness did not last long. Because the crow noticed one day that the pigeons were not left out of the human diet. Fearing that, the crow came to the creator again and said I don't want to live as a pigeon. The Creator said to the crow, What do you want to live as? I gave you life according to your will, but you could not live. Try to be content with your own life by omitting so much. I am telling you something to alleviate the pain you are feeling in your life. Try to listen to my words with your mind: --- The creator asked the crow, have you heard the name of chicken biryani? The crow said, yes I heard. The creator asked the crow again, "Have you heard the name of the rooster polao?" The crow said yes I heard. The creator asked the crow last, have you ever heard of crow polao or cro biryani? The crow replied, "No, I have never heard such a name." The Creator said to the crow: - Then where is your sorrow? No one is catching you, not beating you, not cutting you, not eating you. You are an independent bird. Then why is there so much sorrow or so much trouble with your life. Go and enjoy, rejoice, enjoy your independent life. You can go wherever you want, no one is eating you. The crow realized his mistake and went back to peace. I hope you understand from this story that you are not like everyone else. You are a different person from everyone else. Then what is so sad about your life! Don't be so sad, go and enjoy and enjoy this world. And always remember, you are different from everyone else. And with that in mind, you can succeed in life. Otherwise you have to accept failure.
