#90DaysOfDevOps Challenge - Day-2 - Basic Linux Commands (1)
Tags: devops, linux, 90daychallenge, beginners
Published: 2023-08-31 10:21:27

Welcome to Day 2 of the #90DaysOfDevOps challenge! Today, I'll be diving into the world of basic Linux commands. These commands are essential for navigating and managing files and directories in a Linux environment. Let's explore some of the most commonly used commands and their examples.

## Listing Commands
The ls command is used to list the subdirectories and files available in the present directory. Here's the basic syntax:

```
ls [option_flag] [arguments]
```

Let's look at some examples:

- **ls -l**: This command lists files and directories in a long list format, providing extra information such as permissions, owner, size, and modification date.
- **ls -a**: It lists all files and directories, including hidden ones that start with a dot (.)
- **ls *.sh**: This command lists all files with a .sh extension, helpful when you want to filter files based on a specific pattern.
- **ls -i**: It lists files and directories along with their respective index numbers (inodes).
- **ls -d */**: This command lists only directories, allowing you to view the directory structure without the files. You can also specify a pattern to narrow down the results.


## Directory Commands

- **pwd**: The pwd command prints the current working directory, displaying the absolute path of the directory you're currently in.
- **cd path_to_directory**: This command changes the current directory to the provided path. For example, cd /home/user/Documents will navigate to the "Documents" directory.
- **cd ~** or just cd: Using cd ~ or simply cd without any arguments takes you to the home directory.
- **cd -**: The cd - command allows you to go back to the last working directory you were in.
- **cd ..**: This command moves you one step back in the directory structure. It's useful for navigating up one level.
- **cd ../..**: You can use cd ../.. to change directory by two levels, moving up twice in the directory hierarchy.
mkdir directoryName: The mkdir command is used to create a new directory in a specific location. Here are some examples:

```
mkdir newFolder               # Creates a new folder named 'newFolder'

mkdir .NewFolder              # Creates a hidden directory (prefixing with a dot)

mkdir A B C D                 # Creates multiple directories at the same time

mkdir /home/user/Mydirectory  # Creates a new folder in a specific location

mkdir -p A/B/C/D              # Creates a nested directory structure

```

Congratulations! You've learned some of the basic Linux commands for listing files and directories, navigating through directories, and creating new folders. These commands are the building blocks of your journey towards becoming a DevOps professional.

Stay tuned for Day 3 of the #90DaysOfDevOps challenge, where I'll explore more advanced Linux commands and their practical applications.
Daily Tutorial: Deploy with CLI
Published: 2023-08-31 10:17:16

To gain a better understanding of deployment processes, I'm revisiting the procedures from yesterday. My goal is to redeploy a web application on Azure, and today, I've chosen to exclusively utilize the command-line interface (CLI).

To achieve this, I installed the Azure CLI. Since I'm using Windows, the process was straightforward due to the MSI file. Subsequently, I logged into Azure:

```
az login
```

This command opens a browser-based login page. After logging in, my data is presented in the console in JSON format.

Following that, I navigated to my project folder and published my web application:

```
az webapp up --sku F1 --name <app-name> --os-type <os>
```

This is akin to the "Publish" button in Visual Studio. Initially, I forgot the "up" command, but afterward, everything went smoothly. The value for "--name" must be unique, as it represents a domain in azurewebsites.net. "F1" denotes the free pricing tier, and "--os-type" should be either "linux" or "windows."

It took a while, but eventually, the following message appeared:

```
The application can be accessed at http://azuretestapp310823.azurewebsites.net.
```

The new app can now be inspected in the Azure Portal.

My next step was to introduce changes. I modified the app's code and entered the following command:

```
az webapp up
```

This also went well. All the changes were adopted. Thus, I concluded that performing deployment through the CLI isn't all that complex.

Swinging on a playground is a fun childhood memory for many of us. The feeling of wind blowing through hair and the sensation of flying is hard to forget. But have you ever thought about the benefits of having a swing at home? Integrating a swing into your household can offer numerous advantages, not only for kids but also for adults. This blog article discusses the benefits of adding a swing to your home's interior.



## A Nostalgic Touch to Your Home

Swings can take us back to our childhood days, reminding us of the joyous moments of play, innocent laughter, and carefree afternoons. Incorporating a swing at home can bring a touch of nostalgia, serving as a pleasant reminder of simpler times. It helps to bridge the gap between childhood memories and adult responsibilities, allowing us to relive the carefree days of our past.

## Mental Health and Wellbeing

Swinging is known for its therapeutic properties thanks to its rhythmic motion. Several studies have shown that swinging meditatively releases endorphins that help alleviate stress and anxiety. It is also a necessary sensory experience for children, aiding in their cognitive and motor skill development. Additionally, for adults, a few moments on the swing can serve as mental rejuvenation, providing a refreshing break after a long day.

## Physical Health Benefits

Swinging is not just a fun activity, it also offers a great form of exercise. Regular swinging can improve balance and coordination. Additionally, it strengthens your core muscles and provides an excellent cardiovascular workout, especially when you pump your legs to go higher. Moreover, swinging outdoors can boost vitamin D levels, which is perfect for your overall health, particularly when you bask under the sun.

## Boosts Social Interactions

Having a swing at home can be a great way to promote togetherness and a sense of community. It can be a cozy spot where families can bond and create lasting memories. Imagine parents pushing their children on the swing or couples enjoying a gentle sway together under the stars. Swings encourage conversation, storytelling, and the sharing of moments, all of which help to foster deeper connections between people.

## A Versatile Addition to Home Decor

Swings benefit your health and emotions and can add style to your home. You can personalize them to match your aesthetic, be it modern, bohemian, or traditional. Hanging seats in living rooms or swing chairs on balconies can enhance the appearance of a space, making it both practical and visually pleasing.

## An Invitation to the Outdoors

Having an outdoor swing can encourage spending time outside, which is especially beneficial for children in the digital age. This can help them develop an appreciation for nature and reduce screen time.

## **OSI Reference model :**



![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hz8bo0zybm0pnpjzvc3w.png)



**7 layer of OSI model :**

**Physical layer**

The physical layer is concerned with transmitting raw bits over a communication channel.


**Data Link Layer**

The main task of the data link layer is to transform a raw transmission facility into a line that appears free of undetected transmission errors. It does so by masking the real errors so the network layer does not see them. It accomplishes this task by having the sender break up the input data into data frames and transmit the frames sequentially.

**The Network Layer**

The network layer controls the operation of the subnet. A key design issue is determining how packets are routed from source to destination.

**Transport Layer**

The basic function of the transport layer is to accept data from above it, split it up into smaller units if need be, pass these to the network layer, and ensure that the pieces all arrive correctly at the other end. Furthermore, all this must be done efficiently and in a way that isolates the upper layers from the inevitable changes in the hardware technology over the course of time.

**session layer** 

The session layer allows users on different machines to establish sessions between them. Sessions offer various services, including dialog control (keeping track of whose turn it is to transmit), token management (preventing two parties from attempting the same critical operation simultaneously), and synchronization.

**Presentation Layer**

Unlike the lower layers, which are mostly concerned with moving bits around the presentation layer is concerned with the syntax and semantics of the information transmitted

**Application Layer**

The application layer contains a variety of protocols that are commonly needed by users. One widely used application protocol is HTTP (Hyper Text Transfer Protocol), which is the basis for the World Wide Web. When a browser wants a Web page, it sends the name of the page it wants to the server hosting the page using HTTP.

Inquiry Senior Software Developer Salaries
Published: 2023-08-31 09:58:38

Hello forum members, 

I hope this message finds you well. I am currently conducting research on senior developer salaries across various European countries and would greatly appreciate your insights.

Based on my initial findings, salaries for senior developers in Poland seem to hover around 5,000 euros per month. Similarly, countries such as Hungary, Bulgaria, Romania, and Ukraine appear to offer salary ranges in proximity. 

However, I've encountered challenges in gathering accurate salary information for countries like Greece, Serbia, and Turkey. My aim is to gain a better understanding of potential salary differences within Europe. Despite the general notion of Western vs. Eastern salaries, it seems to me that there might not be substantial variance among Eastern European countries. 

If you have any information or insights regarding senior developer salaries in these countries or others within Europe, I would greatly appreciate your input. Your expertise will undoubtedly contribute to a more comprehensive overview, aiding both myself and fellow researchers in making informed decisions. 

Are there still European countries where senior developers can be found for <4000 euros a month? 

Thank you for taking the time to read my message. I'm looking forward to your valuable contributions. 

Best regards, 
Coen van der Meij



I reached out to numerous recruitment firms situated in different European countries to gather insights on senior developer salary ranges. Unfortunately, I encountered challenges in receiving responses from several firms, particularly those in Turkey and Greece. Moreover, the responses I did receive presented a wide range of salary figures, leaving me with uncertainties about the accuracy of the data. 

To complement my efforts, I also conducted comprehensive research on various online platforms, including Glassdoor. While these estimates provided valuable insights, I've noticed some discrepancies between the Glassdoor figures and the data I received from recruitment firms.

Japanese fishermen and aquaculture industry cry: the government is too stupid, the future...

At 10 a.m. local time on August 24, Japan Fukushima Prefecture, Shinchi Town area fishermen returned to port one after another, three hours after the Fukushima Daiichi nuclear power plant to start the nuclear contaminated water discharged into the sea. According to Japan's Tokyo News 25, these hard-working, dark-skinned fishermen returned home with a full load, but they did not look happy and worried, "Today's fish were not affected by the nuclear contaminated water, but what will happen after tomorrow"?
"All the fishermen cried, the government is so stupid." So say fishermen in Fukushima Prefecture when it comes to nuclear-contaminated water being discharged into the sea.
After Japan started to drain the sea, China announced a total suspension of imports of Japanese aquatic products. Japan's NHK TV said, Japanese fishermen and aquatic practitioners heard the news is very desperate, feel "shocked", "will not be able to survive in the future"; On the other hand, Japan's Tokyo News noted that in the Chinese market, Japanese aquatic products are gradually replaced by Australia, Norway and China's local aquatic products.

In Fukushima, Japan, a fisherman sat blankly by the fishing port.
