General Introduction to Web Scraping using Python
Published: 2023-03-05 10:13:21

Web scraping is the process of extracting data from websites and saving it for analysis or further use. It is a powerful tool for data scientists, researchers, and analysts who need to collect large amounts of data from websites quickly and efficiently.

Amazing right?  

To get started with web scraping, you'll need to have a basic understanding of HTML and CSS, as well as some programming experience. You should also be familiar with the terms "selectors" and "tags," which refer to the HTML elements that you want to extract data from.

First of all, if you haven't done it yet, you should install BeautifulSoup by running the following command:

```
pip install bs4  # For windows users 
pip3 install bs4 # For mac & linux users
```

Here is some sample code in Python that demonstrates how to use BeautifulSoup to extract data from a website:



```
import requests
from bs4 import BeautifulSoup

url = 'https://example.com'
response = requests.get(url)

soup = BeautifulSoup(response.text, 'html.parser')

title = soup.find('title').text
print(title)

links = soup.find_all('a')
for link in links:
    print(link.get('href'))
```


In this example, we first import the requests and BeautifulSoup libraries. We then define a URL that we want to scrape and use the requests library to retrieve the HTML content of the page. We then create a BeautifulSoup object and use its methods to find the title of the page and all the links on the page.

In conclusion, Web scraping can be a powerful tool, but it's important to use it ethically and responsibly. Make sure that you have permission to scrape the websites you are targeting, and be mindful of any terms of service or other guidelines that may prohibit scraping. Additionally, be careful not to overload a website with too many requests, as this can cause performance issues or even lead to your IP address being blocked.
 

Getting Started Code snippets:

Here are some more code snippets that you can use to get started with web scraping in Python:

```
# Scraping data from multiple pages
import requests
from bs4 import BeautifulSoup
base_url = 'https://example.com/page'
for i in range(1, 6):
    url = base_url + str(i)
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    # Extract data from the page

# Scraping data using CSS selectors
import requests
from bs4 import BeautifulSoup
url = 'https://example.com'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
items = soup.select('.item')
for item in items:
    title = item.select_one('.title').text
    price = item.select_one('.price').text
    # Extract data from the item
```

These code snippets demonstrate some of the basic techniques for web scraping using Python and the BeautifulSoup library. With these tools, you can quickly and efficiently extract data from websites and use it for analysis or other purposes.

why people always have a conflict about which is harder: front-end or back-end
Tags: webdev, laravel, web3, react
Published: 2023-03-05 09:58:47

The choice between front-end and back-end development is subjective and depends on individual preferences, skills, and interests. Both front-end and back-end development require specific knowledge and skills, and neither is inherently "harder" than the other. It's important to appreciate the strengths and challenges of both disciplines and find the one that best suits your abilities and interests.

Looking for a beginner friendly Golang open source project to contribute.
Published: 2023-03-05 09:52:48

Hi Gophers, I've been coding in Go for about 2 years now. I've never contributed to any open source project in any language. I'm now looking for open source projects to learn from, contribute and sharpen my Golang and Git skills as I dive in. So far my experience has been in HTML, CSS, JavaScript, Vue JS, Quasar, MongoDb and Golang.

Any advice or guidance is acceptable.
Python list comprehension
Tags: python, programming, tutorial, codenewbie
Published: 2023-03-05 09:25:34

[Python list](https://www.programdoc.com/python/lists) is used to store multiple value with different data types, values inside a list can be accessed or retrieved using index. 

## Create a new list with the addition of each number in an existing list

consider the following example if we want to do some operation the values inside the list we have to python for loop to iterate over each one.
```py
l = [1,2,3,4,5]
m = []
for i in l:
    m.append(i+i)
print("m:", m) # Output: m: [2, 4, 6, 8, 10]
```

Python have its own pythonic style of writing the code in a single line.
```py
l = [1,2,3,4,5]
m = [i+i for i in l]
print("m:", m) # Output: m: [2, 4, 6, 8, 10]
```


## Creating a new list out of the first letter of every word in a string
```py
myString = "Hello World Python Code"

myList = []
for s in myString.split(" "):
    myList.append(s[0])
    
print("myList:", myList) # Output: myList: ['H', 'W', 'P', 'C']
```
Using list comprehension 
```py
myString = "Hello World Python Code"

myList = [s[0] for s in myString.split(" ")]

print("myList:", myList) # Output: m: [2, 4, 6, 8, 10]
```

Uses Sentinel
Tags: github, workflow, bash, actionshackathon
Published: 2023-03-05 09:23:17

## Uses Sentinel

Uses Sentinel is a GitHub action that scans all `.yml` files in the `.github/workflows` directory of a GitHub repository and performs two checks on the `uses` fields in the YAML files:

1. Checks if any `uses` field contains the version `main`, `master`, or `latest`, which are considered unsafe versions to use. If a `uses` field contains any of these versions, a warning message is printed to the console.

2. Checks if the `uses` field references the latest version of the action by checking the GitHub repository's tags. If the `uses` field does not reference the latest version, a warning message is printed to the console.

Uses Sentinel is written in Bash only and has no dependencies.

## Usage

To use Uses Sentinel in your GitHub repository, create a new workflow file (e.g., `.github/workflows/uses-sentinel.yml`) with the following content:

```yaml
name: Uses Sentinel
on: [pull_request]

jobs:
  uses-sentinel:
    runs-on: ubuntu-latest
    steps:
      - name: Uses Sentinel
        uses: maork-elementor/uses-sentinel@1.0.0
```

* This will run Uses Sentinel on every pull request in your repository.

## Inputs
```yaml
jobs:
  uses-sentinel:
    runs-on: ubuntu-latest
    steps:
      - name: Uses Sentinel
        uses: maork-elementor/uses-sentinel@1.0.0
        with:
          exlude:'exlude.yml,exlude2.yml,exlude3.yml'
```
exlude - list of files to exlude from the scan


## Output Example
Here's an example output from Uses Sentinel:

```
Some actions are not safe to use or not updated

Bad versions:
yml: ./.github/workflows/ci.yml, use: actions/checkout@main version: main, It not safe to use main, master or latest

Not updated actions:
yml: ./.github/workflows/ci.yml, use: actions/setup-node@v1 current version: v1.0.0, latest version: v2.1.4
```

This output indicates that the .github/workflows/ci.yml file contains an unsafe version (main) of the actions/checkout action and an outdated version (v1.0.0) of the actions/setup-node action.

Diatonic scale builder
Tags: rust, music, beginners, python
Published: 2023-03-05 09:17:31

When I first started learning programming (Rust) in November 2021, I rapidly had the idea to write an algorithm to calculate diatonic harmonies from any note. At the end of December 2021 I started my first attempts and wrote some nonsense in half a year. Recently I decided to rewrite the project from scratch and managed [it](https://github.com/antonovmike/scale_finder_2) literally in a couple of days. Because of the problem with getting a new place to live, it's hard for me to calculate the time I spent. In general, I am satisfied with the result. There is one last problem left to solve: automatically fixing the "wrong" alteration signs of the root note. Because we don't want to use weird cases like E sharp which is F or Fb which is E and C sharp which is H and Hb which is C. Have to write the documentation. I may try to turn this project into a crate. It would also be interesting to rewrite the project in Python.
What I lack now is practice in the real project. But there is only job for at least middles and you can't get into a real project without experience in the real project. I should look for a job where I don't get paid. To at least get experience in a real project

Need help in building a new application from scratch
Tags: dlt, web3, programming
Published: 2023-03-05 09:04:16

Hello All,
These days data is evolving, expanding and eating up our storage.
I've been following DLT since 2010 and based on my work on data storage, I'm trying to fix a data deduplication issue which can actually optimize storage space. 
Thinking to start it using lists and cursors with the 94 English US keyboard characters as pointers have much smaller footprint.
What language is better to implement this application?
Which database is best to implement this kind of chain?
Is there any other way to tackle this issue?
Feedback and ideas are much appreciated.
Polyfill for map in javascript
Tags: javascript, interview, polyfill
Published: 2023-03-05 08:47:47

The `map()` method in JavaScript is **used to iterate over an array and apply a function to each element in the array, returning a new array with the results**. For those who are new to javascript here is a basic example of how `map()` works

```
// Define an array of numbers
const numbers = [1, 2, 3, 4, 5];

// Use the map() method to square each number in the array
const squaredNumbers = numbers.map(function(number) {
  return number * number;
});

// Output the new array of squared numbers
console.log(squaredNumbers); // [1, 4, 9, 16, 25]

```

For an indepth understanding of `map()` please refer this [link](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map) 

As seen above `map()` is a very useful method, but not all browsers support it. In this blog post, we will create a polyfill for the `map()` method so that it can be used in all browsers.

Here's the code for the `map()` polyfill -

```
if (!Array.prototype.map) {
  Array.prototype.map = function(callback, thisArg) {
    if (typeof callback !== 'function') {
      throw new TypeError(callback + ' is not a function');
    }

    var newArray = [];

    for (let i = 0; i < this.length; i++) {
      if (this.hasOwnProperty(i)) {
        newArray[i] = callback.call(thisArg, this[i], i, this);
      }
    }

    return newArray;
  };
}
```

Let's break down this code -

1. First, we check if the `map()` method already exists on the `Array prototype`. If it does not exist, we create our implementation.
2. We define the `map()` function on the `Array prototype`, taking two arguments: a `callback `function and an optional `thisArg` parameter.
3. We check if the `callback `argument is a function, and `throw` a `TypeError` if it is not.
4. We create a new empty array to hold the results of the mapping operation.
5. We iterate over each element in the array, using the `hasOwnProperty()` method to skip any non-existent elements such as properties added to the array's prototype.
6. For each element, we call the callback function with the element, the index, and the original array as arguments, using the `call()` method to set the `this` value to `thisArg` if it is provided.
7. We store the result of the callback function in the new array.
8. We return the new array containing the mapped results.

And that's it! With this `map()` polyfill, you can use the `map()` method on arrays in all browsers, even if they do not support it natively.
Quality Metrics
Published: 2023-03-05 08:16:48

## Code Coverage
The percentage of code that is covered by (automated) unit tests.

## Abstract Interpretation

Let's explain the abstract with an example.
```
if (obj == null) {
    obj = getObject();
}
obj.method();
```

Here in the above example there is one problem abstract interpretation may detect that is the obj variable may have the value null even after line 2. 

## Cyclomatic Complexity

Programs with a lot of conditional statement or loops are more complex. This means maintainability of the program is hurt, since it is hard to understand for new developers working on it.

## Compiler Warnings

Compiler warnings are potential errors in the source code that are discovered during compilation. These include syntactic errors for which the semantics are easily misinterpreted, portability issues and type errors.

## Coding Standards

Coding standards provide rules for software developers to follow while writing code. The most important reason for coding standards is maintainability; a clear set of rules makes it easier for programmers to understand the meaning of code.

## Code Duplication

Code Duplication is a software metric that indicates the amount of source code that occurs more than once in a program.

## Fan Out

The fan out metric indicates how many different modules are used by a certain module. 

For Python, the number of modules mentioned in the import statement are counted. from-import counts as 1.
