Mastering Word Frequencies: A Python Solution to the Coding Challenge
Tags: python, programming, beginners, tutorial
Published: 2023-07-18 07:00:59

Problem-solving skills are the key to mastering complex challenges. Let's dig into a fascinating coding problem that involves reading a file, counting word frequencies, and generating a unique word frequency list. I'm going to explain this using the Python programming language. We will guide go over a comprehensive solution to this simple yet challenging problem. Mastering this problem will sharpen some extremely important programming skills.

The objective of this challenge is to develop a program that reads an input file containing a list of words separated by commas, determine the frequency of each word in the file and present the result, excluding any duplicates.

---

#Example

To better understand the problem, let's consider the following example:

Suppose we have an input file named input1.csv with the following content:

```
hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy

```

The expected output for this program would be:

```
hello 1
cat 2
man 2
hey 2
dog 2
boy 2
Hello 1
woman 1
Cat 1
```

---

#Solution

To reach a solution to this coding problem, we will make use of the powerful built-in csv module. The following code presents a straightforward solution that will lead us to the desired output:

```
import csv

user_input = input("Enter the name of the input file: ")
word_freq = {}

with open(user_input, 'r') as csvfile:
    input_reader = csv.reader(csvfile, delimiter=',')

    for line in input_reader:
        for word in line:
            if word not in word_freq:
                word_freq[word] = 1
            else:
                word_freq[word] += 1

for word, frequency in word_freq.items():
    print(f"{word} {frequency}")
```

At the beginning of our solution we prompt the user to enter the name of the input file. Next, we create an empty dictionary called word_freq to store the word frequencies. We open the file using the csv.reader() method and read it line by line. Each line is then split into individual words using the comma delimiter.

On each iteration, we check if each word already exists in the word_freq dictionary. If the word is not present, we add it to the dictionary with an initial frequency of 1. If the word already exists, we increment its frequency by 1.

Finally, we loop through the word_freq dictionary using the items() method to access both the word and its frequency. We print each word and its frequency using string formatting.

---

Problem-solving is a programmer's main skill, finding a comprehensive solution to a common coding challenge like this one will sharpen this necessary skill. By leveraging Python's powerful csv module, we read an input file, counted word frequencies, and created a frequency dictionary. The step-by-step approach displayed in this solution arms programmers of all levels with valuable insights, upgrades their problem-solving skills and expands their programming knowledge. I hope you had fun solving this problem and experimenting with it as much as I did. Happy coding! 😎

What is a Logger Middleware
Tags: apacheage, postgres, node
Published: 2023-07-18 05:56:14

**What is a Logger Middleware?**

A logger middleware in Node.js is a piece of code that intercepts incoming HTTP requests and logs information about them. It helps in monitoring and debugging server-side applications by providing insights into request details such as the HTTP method, URL, timestamp, and other relevant information.

**Setting up the Project**


Before we dive into the code, make sure you have Node.js installed on your system. Create a new directory for your project, open a terminal, and navigate to the project directory. Run the following command to initialize a new Node.js project:

```
$ npm init -y
```

This will create a new package.json file, which will be used to manage project dependencies.

**Installing Dependencies**


We'll be using the Express.js framework to create our server and the morgan library for logging. Install these dependencies by running the following command:

```
$ npm install express morgan

```

Once the installation is complete, you can proceed to the code implementation.

**Implementing the Logger Middleware**

Create a new file called app.js and open it in your preferred code editor. Let's begin by requiring the necessary modules and setting up the basic Express server:

```
const express = require('express');
const morgan = require('morgan');

const app = express();
const port = 3000;

app.use(morgan('dev'));

// ... Additional code will be added here

app.listen(port, () => {
  console.log(`Server listening on port ${port}`);
});

```

Here, we import the required modules and create an instance of the Express application. We also specify the port on which the server will run. The morgan('dev') statement sets up the logger middleware using the 'dev' predefined format, which provides concise logging output.


**Testing the Logger Middleware**

To test the logger middleware, let's create a simple route that will respond with a sample JSON message. Add the following code below the existing code:

```
app.get('/', (req, res) => {
  res.json({ message: 'Hello, world!' });
});

```

**Logging Output**

With the server running, open your browser and navigate to http://localhost:3000. You should see the JSON response message. Meanwhile, in your terminal, you'll notice logs generated by the logger middleware in the 'dev' format:

```
GET / 200 6.802 ms - 20

```

Customize your VSCode IDE
Tags: vscode, productivity
Published: 2023-07-18 05:26:43

Vscode is a greate IDE, and it is the first choice of many developers. In this article I will share tips you can use to be more productive with Vscode.

Many times we work with mulitple windows of Vscode, for example, while developing a fullstack web app, you have a window for frontend and another for backend. In that scenerio if often happens that you accidently messup with the code and write it on wrong folder, or just search a file which is not present in that folder.

We can customize Vscode from its settings, but we don't want the changes to be reflected in all of our Vscode instances. We want the changes to persist on specific instances.

Steps:

1. Create a `.vscode` folder in project's root.
2. Create `settings.json` file in it.
3. Customize the looks according to the following image reference.

Importance of Software Testing
Tags: webdev, beginners, programming, react
Published: 2023-07-18 05:17:04

Software testing is the process of evaluating a software application or system to ensure that it meets specified requirements and performs as expected. It involves executing the software to find defects or errors and ensure its quality, reliability, and functionality.

Software testing is the process of evaluating and verifying that a software product or application does what it is supposed to do. The benefits of testing include preventing bugs, reducing development costs, and improving performance.

Software testing typically involves the following key activities:

Test Planning: Defining the objectives, scope, and approach for testing. This includes identifying test objectives, test strategy, test deliverables, and resource allocation.

Test Design: Creating test cases and test scenarios based on the requirements and specifications of the software. Test design involves determining what to test, how to test, and what data to use for testing.

Does NPM really stands for "Node Package Manger" ?
Tags: node, npm, javascript
Published: 2023-07-18 04:47:49

"Hey there, curious minds! Ready for some NPM fun facts? 🤩 NPM, the JavaScript developer's best buddy, is the one and only package manager you'll ever need! 🎉

Here's the scoop: NPM doesn't actually stand for "Node Package Manager" as many believe. It's an independent rockstar in the coding world, strutting its stuff without any full form! 🎸

So, what does NPM stand for, you ask? Drumroll, please... nothing! Yep, it's simply N-P-M – the trio of letters that brings joy to developers everywhere! 🥳

Don't take my word for it, visit their official website at https://www.npmjs.com, and you'll see – no fancy acronyms, just the funky name itself! 🕺

check this out: https://github.com/npm/npm-expansions

But here's the best part: NPM has sparked creativity among developers, and they've come up with hilarious and imaginative expansions for N-P-M. It's like a never-ending party of wordplay! 🎈

So, next time someone says NPM means "Node Package Manager," drop the knowledge bomb and tell them the truth – NPM is the enigma of the coding world, making the web a better place one package at a time! 🌐📦

Get ready to embrace the funky charm of NPM and join the groovy squad of JavaScript developers! Happy coding!" 🚀🌈
TIL about interesting CSS resources
Published: 2023-07-18 04:15:45

While slowly progressing through TechPrep, I found out about some very cool resources to practice CSS.

Here are some of my favorite ones.

- [Flexbox Froggy](https://flexboxfroggy.com/)

![Flexbox Froggy](https://flexboxfroggy.com/images/screenshot.png)

It is kind of silly but also so useful. I will probably get back to it several more times until it sticks.

Also learned some interesting things about CSS : when setting the direction to reverse, start and end are also reversed. It makes sense, but good to know!

`#pond {
  display: flex;
  flex-direction:row-reverse;
  justify-content:flex-end;
}`

Although, reversing the row does not reverse start and end for align-items. Makes sense also!

Flutter Accessibility - Lost focus after Getx modal dialog has been closed
Published: 2023-07-18 03:55:45

We are trying to make our application accessible with screen readers for visually impaired people.

One problem is, that after a modal dialog like Get.bottomSheet() was closed, the focus goes back to the top of our page. For blind people this behaviour is very heavy to get along with. I tried with the below approach but not working. Can any one suggest the best approach to achieve this?

```
void openGetxBottomSheet({FocusNode? focusNode, required Widget view ,bool isDismissible = true , bool enableDrag = true, bool isScrollControlled = false}) {
    Get.bottomSheet(view, isDismissible: isDismissible, enableDrag: enableDrag, isScrollControlled: isScrollControlled).whenComplete(() {
     Future.delayed(const Duration(seconds: 4), () {
        focusNode?.requestFocus();
      });
    });
  }
```

Below is the custom TextField,

```
FocusNode selectBoxFocusNode = FocusNode();

CustomTextField(
                focusNode: selectBoxFocusNode,
                heading: "Amount",
                maxLength: 16,
                showDropDown: true,
                showCursor: false,
                readOnly: true,
                controller: TextEditingController(text: ""),
                onTap: () {
                  openGetxBottomSheet(
                      focusNode: selectBoxFocusNode,
                      view: "Sample data"
                      isScrollControlled: true,
                  );
                  setState(() {
                   
                  });
                },
              );

TIL #2 Codespace
Tags: beginners
Published: 2023-07-18 03:44:38

TLDR: Codespace = VS Code in browser

I think it's crazy that a tool as powerful as VS Code can be done all within a browser, without needing the extensive download times, extensions, and packages (unless that comes in the future). Codespace is a really neat tool, and going through this assignment helped me understand a new way to perform source control. I was so used to typing in the 'git push', 'git commit - m', etc. that I didn't realize that Codespace just needed 3 clicks instead. Well, maybe VS Code can do that too, but when I used it beforehand I didn't know it was that simple. Leaving myself a few notes here, in case I need the refresher especially with the new 'rackup' and 'rake grade' commands.

Checking live preview and running tests in the terminal 
1. Click the + sign to add another Bash prompt
2. Type "rackup" as the command (no "")
3. Live preview complete! 
4. Click on ports 
5. Under 'Local Address' click the globe to open in new browser
6. Git Source Control (left side squiggly icon)
7. Add a comment describing changes
8. Commit/ Sync Changes
9. Go to normal Bash Prompt
10. Type "rake grade"
11. Open Rake Grade assignment and copy paste the assignment token (rinse and repeat until everything works, click the red tests to find issues!)

P.S- I'm going to look into what exactly the Bash terminal is (and puma!)

Counter App
Published: 2023-07-18 03:29:58

**App Component**
In this blog I will explain about how i completed assignment of counter App.
First I created counter App component inside component folder and import counter App in App component.

In App component. I used useState hook for that we need to import useState first from 'react' and declared initial state as 'light theme'.`const[theme,setTheme]=useState("light");`
I used two icons inside ternary operator and  for each icon used function whenever user click on icon state get updated according to that changes will display. 
To style App component I used class selector.Declared  class for each button which will change according to the state.
className=`{${theme}-backgroundColor}` and wrote css for  both the themes and that class will apply css to component according to state. 
Passed 'theme' to counter App component as props because whenever state changes we need make changes according to theme in counter App.

**Counter Component**
In counter App component. First I import style file. I used one input for getting number from user and three buttons to update counter. Here ,I used useState to store number or update number entered by user.
`const[num , setNum]=useState("")`
I declare initial state as double quote because if user try to increase to decrease number without entering any number in input it will give error to solve this I used ternary operator
whenever value of num become ""  direct pass 1 or -1 else increment or decrement number by one.
First button is for decrease number for that I used onClick event passed one function it will decrease number by one.
Second button is for reset counter for that also I used onClick event passed one function that will reset the counter.
Third button is for increase number for that also used onClick event and passed one function that will increase number by one.
To style counter app component. I used class selector for each button gave one class which will change according to state and wrote css  for each class.
