May I ask you a favor (list of accounts worth to be blocked)?
Tags: followers, spam
Published: 2024-01-06 12:08:51


I am quite new to DEV and experiencing that the level of spam accounts advertising things from steel sheets for construction work in Dubai to whatever else following my account makes almost the entire list of my followers (exceptions confirm the rule). 

May someone point me to a daily updated list of accounts worth to be blocked? Or point me to another way of knowing which articles and accounts are really worth attention and are in the original spirit of DEV which is bringing software developer together?

The intended audience here is advanced beginners. Maybe you've taken a Python course, or completed a tutorial. Maybe you have a basic, but solid understanding of the language. Maybe you have a Python script in place that does work for you. Great!

Now what? How do we move that understanding into real, working software?

In this series, we will be working with Python 3. Poetry requires at least Python 3.8.

## Pipx

[Pipx](https://pipx.pypa.io/) is a package manager that distributes Python code.

I am on a Mac, so I can install Pipx via Brew:

```sh
brew install pipx
```

## Poetry

[Poetry](https://python-poetry.org/docs/) is a tool for dependency management and packaging. Traditionally a tool called virtualenv has been the standard in Python, but it seems like that is transitioning from `requirements.txt` to `pyproject.toml`.

```sh
pipx install poetry
```

Poetry provides some really great [documentation](https://python-poetry.org/docs/basic-usage/) to help get you started.
In this series, we will be using Poetry because it has a modern interface that adheres to the `pyproject.toml` standard. It will also enable us to learn how to take our Python projects from a beginner's script to a complete package.
SSH: "Connection refused" Fix - Ubuntu Server
Published: 2024-01-06 11:28:52

The "Connection refused" error typically indicates that the SSH service is not running on the specified host, or a firewall is blocking the connection.

**Error below**

> root@00bc17d6e6f8:/# ssh -v ubuntu@100.24.238.153
> OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014  
> debug1: Reading configuration data
> /etc/ssh/ssh_config  debug1: /etc/ssh/ssh_config line 19: Applying
> options for *  debug1: Connecting to 100.24.238.153 [100.24.238.153]
> port 22.  debug1: connect to address 100.24.238.153 port 22: 
> Connection refused ssh: connect to host 100.24.238.153 port 22:
> Connection refused root@00bc17d6e6f8:/#

Here are a few steps to troubleshoot the issue:

1. **Check SSH Service:**
   Ensure that the SSH service is running on the remote server. If you have access to the server, you can check and restart the SSH service using the following commands:

   ```bash
   sudo service ssh status
   sudo service ssh restart
   ```

2. **Firewall Configuration:**
   Make sure that the firewall on the remote server is not blocking incoming connections on port 22 (the default SSH port). You can temporarily disable the firewall or allow SSH traffic through it.

3. **Security Group / Network ACLs (for AWS):**
   If you are using Amazon Web Services (AWS), check the security group and network ACL settings for the instance. Ensure that incoming traffic on port 22 is allowed.

4. **Check if SSH is Listening:**
   On the remote server, check if SSH is listening on the specified port (22 by default). You can use the following command:

   ```bash
   sudo netstat -tulpn | grep 22
   ```

   This should show an entry for the SSH daemon (`sshd`) listening on port 22.

5. **Restart SSH Service on the Remote Server:**
   If the SSH service is running, try restarting it on the remote server:

   ```bash
   sudo service ssh restart
   ```

6. **Check Server Logs:**
   Examine the logs on the remote server for any SSH-related issues. The location of the logs may vary depending on your server's operating system. Common locations include `/var/log/auth.log`, `/var/log/secure`, or `/var/log/messages`.

7. **Confirm IP Address:**
   Double-check that the IP address (100.24.238.153 in this case) is correct and corresponds to the intended server.

After performing these steps, try connecting again:

```bash
ssh -v ubuntu@100.24.238.153
```

The `-v` option provides verbose output and might give more details about the connection issue. If the problem persists, inspect the logs and error messages for further troubleshooting.

What is an OPTIONS Request in an API call?
Published: 2024-01-06 10:29:36


#####If you are reading this blog then you must have come across the OPTIONS request in an API call, but what exactly is an Options Method

well if you make a server request from the front end to the backend, and log the requests made to the server by using a logging package (in the Context of Nodejs) you will get a result like this.


```
OPTIONS /api/users/signup 204 2.247 ms - 0
POST /api/users/signup 201 519.913 ms - 333
```

in this example, we are signing up the user, and the endpoint is

 `/api/users/signup`

Now we know what a POST method is but what is this OPTIONS method? 

#Let's break this down,


**HTTP Method**: OPTIONS

**Endpoint**: /api/users/signup

**Status Code**: 204

**Response Time**: 2.247 ms

**Response Size**: - 0 (indicating a response with no content)

_To put it in simple words an OPTIONS request is a part of the CORS (Cross-Origin Resource Sharing) mechanism._

The OPTIONS method is often used to request information about the communication options available for a target resource, including the permitted HTTP methods or the supported headers. It's part of the HTTP/1.1 protocol, and browsers often send OPTIONS requests as a pre-flight check before making a cross-origin request (e.g., for a POST request with certain headers).

#in our current example : 

The client, typically a web browser, is checking what methods are allowed on the `/api/users/signup` endpoint and what headers can be used in the actual request.

**Status Code (204):** This status code indicates that the server successfully processed the OPTIONS request, and there is no additional information to send in the response payload. thus the response is empty, as indicated by - 0.

#In a nutshell: 

Browsers often perform this pre-flight request to determine if the actual request (e.g., a POST request) will be allowed by the server. The server responds with information about the allowed methods, headers, and other details. 
Thus HTTP OPTIONS request method is useful for determining what commands are available for use on a target server or for a specific resource.
Designing pages for scanning, not reading
Published: 2024-01-06 10:26:16






1/ To make a page easy to understand quickly, it's crucial that how things look on the page clearly reflects their connections. This involves highlighting important elements with bigger text, bold fonts, distinct colors, extra space, or positioning them higher on the page. This creates a clear 
visual order for easier 
comprehension.
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vtkkqbbw2u74my2ytzt6.jpeg)

---

2/ If things logically go together, they should visually connect on the page too. Grouping similar things under a heading or presenting them in a similar style helps convey their connection seamlessly.
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ounjolnjcflchs3ql5jk.jpeg)

---

3/ Visual nesting is a powerful tool to illustrate what's part of what. Take a section heading like "Computer Books" - it sits above a specific book title, visually covering the entire content area. This clearly indicates that the book is part of that section. The book title, in turn, spans the elements describing the book.

SynoGut Reviews (Nobody Tells You This) SynoGut Dietary Supplement 2024

This is why the belief makes us mighty. These are the secrets to that assignment. I'm behind the woodshed again. That modulation probably comes low on your list. You cannot ignore this: It topic should be continued at a later date. Indeed, I know. 

The first detail you may need to do is to figure out what you know relevant to your idea. I must admit I had no it at that time. I don't squander it on their recipe and such if this was that hot. From the studies over the decades, it is a proven hypothesis.

Someone with the knowledge of that excuse is needed in order to do it. Newer doing this types also have these capacities, enabling them to be utilized in that way. There's actually something alarming here. Your bias always has an advantage. 

You have an mundane opportunity to teach them as this concerns a buzzword. I got several more SynoGut as though improbably, there's a larger problem here. That is a sly way of getting this opportunity that you desperately want. That's the time for quite a few last minute measures.

Service Discovery :
Published: 2024-01-06 08:58:46

In a microservices architecture, a discovery Server is a component that helps microservices locate and communicate with each other within the distributed system. Since microservices contains 
number of services so ,for storing all the services together at a location we have to use service registry at that point . Commonly used service registries include tools like Eureka, Consul, and ZooKeeper. 
By using Service discovery  and service registry, microservices can achieve better scalability, flexibiliy.

1) In Springboot based application we can use Service Discovery(Service Registry) as Server by adding a dependency in pom.xml file :

```
<dependency>
   <groupId>org.springframework.cloud</groupId> 
   <artifactId>spring-cloud-starter-netflix-eureka- 
    server</artifactId>
</dependency>
```
After adding dependency the next step is to add the scripts in application.yml or property file :
                         
 ```
                  eureka:
                     instance:
                           hostname: localhost
                      client:
                            register-with-eureka: false
                            fetch-registry: false
                  sever:
                      port: 8761
```
 
by adding above scripts the service will acts as a Eureka server where we can store all the client services .

 2) For Using Service Discovery as client we have to add another dependency in pom.xml file:

```
  <dependency>
     <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-starter-netflix-eureka- 
       client</artifactId>
  </dependency>
```
     
Next step is to add scripts in Application.yml or property file :

```   
      eureka:
            instance:
              prefer-ip-address: true
         client:
             register-with-eureka: true
             fetch-registry: true
             serviceUrl:
                defaultZone: http://localhost:8761/eureka/
```

by adding these scripts the service will act as a eureka client and automatically store into Service Registry

Note that : netflix-eureka-server  are  the servers of Netflix itself which is configured by spring developers for using it in springboot application .
