Python TSV to Parquet File Format.
Published: 2023-04-06 14:54:31

**TSV:**

Tab-separated values (TSV) is a simple, text-based file format for storing tabular data.[1] Records are separated by newlines, and values within a record are separated by tab characters. The TSV format is thus a delimiter-separated values format, similar to comma-separated values.

**Parquet:**
What is Parquet? Apache Parquet is an open source, column-oriented data file format designed for efficient data storage and retrieval. It provides efficient data compression and encoding schemes with enhanced performance to handle complex data in bulk.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4dvqyt7zbg468pulxj6l.png)

**Benefits of Parquet**

1. Good for storing big data of any kind (structured data tables, images, videos, documents).
2. Saves on cloud storage space by using highly efficient column-wise compression, and flexible encoding schemes for columns with different data types.
3. Increased data throughput and performance using techniques like data skipping, whereby queries that fetch specific column values need not read the entire row of data.


**Advantages of Storing Data in a Columnar Format:**

1. Columnar storage like Apache Parquet is designed to bring efficiency compared to row-based files like CSV. When querying, columnar storage you can skip over the non-relevant data very quickly. As a result, aggregation queries are less time-consuming compared to row-oriented databases. This way of storage has translated into hardware savings and minimized latency for accessing data.
2. Apache Parquet is built from the ground up. Hence it is able to support advanced nested data structures. The layout of Parquet data files is optimized for queries that process large volumes of data, in the gigabyte range for each individual file.
3. Parquet is built to support flexible compression options and efficient encoding schemes. As the data type for each column is quite similar, the compression of each column is straightforward (which makes queries even faster). Data can be compressed by using one of the several codecs available; as a result, different data files can be compressed differently.
4. Apache Parquet works best with interactive and serverless technologies like AWS Athena, Amazon Redshift Spectrum, Google BigQuery and Google Dataproc.

From Art to Coding
Tags: webdev, beginners, career, codenewbie
Published: 2023-04-06 14:52:35

Hey there! My name is Mahmoud, and I'm thrilled to share my coding journey with you on dev.to. At 24 years old, I've been immersed in the world of art for six years, and it's been a huge passion of mine. However, after doing freelance artwork for some time, I found that it wasn't working out and I wasn't enjoying it anymore.

In addition to my love for art, I'm also taking care of my sick parents and doing everything I can to support them. However, art was unfortunately not able to support me and them, so I had to find an alternative.
During a break from art, I decided to try my hand at graphic design, and while I enjoyed it, I still felt like it wasn't the right fit for me.

That's when I turned to coding. I've always been fascinated by it, and I felt like it was the perfect time to take it seriously. As I write this post, I've just finished the free Javascript course on scrimba, and I couldn't be happier about taking this step!

So far, I've been able to create a little website, a fun project using HTML and CSS, as well as a chrome extension. I'm excited to make new friends and learn from others, while also helping people who are just starting out on their coding journey.


Here's a link to my little HTML/CSS website:
[SBORPSERS - a parody of Japanese Gachapon systems](https://othm-mahmoud.github.io/sborpsers.github.io/sborpsers/)

Now that I've learned Javascript I'd like to take this project to the next level, make it cooler, make it move, and even do all sorts of animations for it!

From today onwards, I will be documenting my coding journey over here and keeping note of every new thing that I do!

I'm looking forward to sharing my experiences and learning from all of you on this platform. Thanks for joining me on this journey!

I am trying to update my angular project from 7 to 8 (eventually I want to update to the latest). Following the Angular Update Guide here https://update.angular.io/?v=7.2-8.2 gives the following error after invoking the first command instruction cmd /C "set "NG_DISABLE_VERSION_CHECK=1" && npx @angular/cli@8 update @angular/cli@8 @angular/core@8"

I recently talked about [WordPress.com and WordPress.org](https://dev.to/gunkev/wordpresscom-vs-wordpressorg-which-one-should-you-use-4ho0) in my previous articles and actually I have been getting requests from people asking what WordPress actually is. Today you will finally feel relief cause I will give you a brief introduction to WordPress. So guys sit and get a cup of tea to savour this.
WordPress… just another CMS

WordPress is actually a free and open source Content Management System written in PHP and associated with MySQL or MariaDB databases. Initially, it was created as a blog publishing-System. But it has evolved to include different web content types (such as online stores, membership websites, forums, and media galleries…).
CMS… What is it?

Content System Management also known as CMS is simply an application that is used to manage web content. In general, it allows a contributor or contributors to create, edit, publish or destroy content(web pages, articles…). A contributor can be any person who has access to a WordPress Dashboard

WordPress is equally one of the most popular content system management used today. It has also been used for other application domains such as pervasive display systems.

The software was released under the GPLv2 license. Founded by an American developer Matt Mullenweg and Mike Little an English developer. WordPress is also called a factory that makes webpages. It comes along with many tools to ease management. Some of these tools include themes and plugins.

Below you will find a screenshot of a section of WordPress Dashboard

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/k8igv7y49ofzukd57v57.PNG)

As you can see in the shot above, the WordPress Dashboard has many tools you can use to manage your web content. To have a better experience just install WordPress and take a look around. If you would like to set up WordPress on your own don’t worry here is a tutorial on how to install it locally.

To conclude, WordPress is an application used for building web platforms. Be it a blog, a website, or a portfolio, WordPress facilitates and eases your efforts to build such platforms. For example [MangAnime tradnow](https://www.tradnow.co) and [Learndevtools](https://www.learn-dev-tools.blog) are two blogs which talks about anime and development build essentially with WordPress

Last but not least there exist different versions of WordPress. Some of us can use WordPress.com(Practically no coding). Then developers have the chance to get beautiful documentation in order to customize and bring in some innovations with WordPress.org.

I hope I was able to answer most of your questions guys. Feel free to ask more questions. I will be glad to understand and help you.
Simplify Your Debugging Process with Visual Studio Group Breakpoints
Tags: productivity, programming, visualstudio
Published: 2023-04-06 14:10:50

Visual Studio is a powerful integrated development environment that provides many useful tools for developers. One such tool is the Group Breakpoints feature, which allows you to set breakpoints for multiple lines of code at once. This can be especially useful when debugging complex applications that have many different code paths, or when debugging code that is spread out over multiple files.

![Breakpoints](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gshnisl0jqbz5m07y9sh.png)


To use Group Breakpoints in Visual Studio, follow these steps:

- Open the code file that you want to debug.
- Select the lines of code that you want to group together.
- Right-click on the selected lines of code and choose "Breakpoint" from the context menu.
- In the Breakpoint menu, select "Insert Group Breakpoint."

Once you have set a Group Breakpoint, Visual Studio will display a blue rectangle in the left margin of the code editor to indicate the location of the breakpoint. When the code reaches this breakpoint, the debugger will stop and allow you to inspect the state of the application.

Group Breakpoints can be especially useful when debugging code that is spread out over multiple files. For example, if you have a complex function that is defined in multiple files, you can select all the lines of code that make up the function, right-click, and choose "Insert Group Breakpoint." This will create a single breakpoint that covers all the lines of code for the function, making it easier to debug the code and find any errors.

Group Breakpoints can also be useful when debugging code that has multiple methods. Rather than setting individual breakpoints for each method, you can select all the lines of code for each method, right-click, and choose "Insert Group Breakpoint." This will create a single breakpoint that covers all the lines of code for each method, making it easier to debug multiple methods at once.

To remove a Group Breakpoint, simply right-click on the blue rectangle in the left margin and choose "Delete Group Breakpoint" from the context menu.

In conclusion, Group Breakpoints are a powerful tool for debugging complex applications in Visual Studio. They can help you save time and effort by allowing you to set breakpoints for multiple lines of code at once, making it easier to debug your code and find any errors. By following the steps outlined above, you can easily use Group Breakpoints to debug your own applications and streamline your development workflow.
How Web Works.....

**Websites are built using a combination of programming languages like HTML, CSS, and JavaScript. When you type a website's address into your browser, it sends a request to the website's server, which responds with the website's files.**
**


These files include the website's code, images, and other assets. Your browser then interprets the code and renders the website on your screen.

Behind the scenes, web servers, databases, and other technologies work together to ensure that the website runs smoothly and can handle user requests.

Overall, websites rely on a complex infrastructure of software and hardware to deliver the content and functionality that we see and interact with on a daily basis.

Supercharging your Web Development with React: A Comprehensive Guide.
Published: 2023-04-06 13:21:54

As a developer you know React is a popular JavaScript library that enables developers to create dynamic and responsive user interfaces (UIs) for web applications. React simplifies web development by allowing developers to break down complex UIs into smaller, reusable components. In this technical write-up, we'll explore the basics of React and provide coding examples to demonstrate how it works.


## Getting Started with React


To get started with React, you need to have a basic understanding of HTML, CSS, and JavaScript. Once you have that foundation, you can use the React library to build more complex UIs. Here's an example of a simple React component:




![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/360oxl8q0zele6ko8ql6.png)


This code defines a React component called `Welcome` that takes in a `props` object and returns an HTML element with a dynamic greeting based on the `props` value.


## Breaking Down React Components

React components are the building blocks of a React application. They are reusable and can be composed together to create more complex UIs. Let's take a closer look at the `Welcome` component and its parts:


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/p2tewiduumxiupvk6ek0.png)

This line imports the `React` library, which is needed to define React components.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2lbcyl7xk0zi15jrtf3q.png)

This code defines a function called `Welcome` that takes in a `props` object as an argument. The function returns an HTML element with a dynamic greeting based on the `props` value.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/aws3ojmsh0r8g88gxr4t.png)

This line exports the `Welcome` component so that it can be used in other parts of the application.

## Rendering React Components


Once you've defined your React components, you need to render them to the DOM. Here's an example of how to render the `Welcome` component we just created:


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/lri3g2sqscsar6m0s617.png)

This code imports the `ReactDOM` library, which is used to render React components to the DOM. It then renders the `Welcome` component with a `name` prop of "Sidicode" to the element with an ID of "root".

## Wrapping It Up.

React is a powerful tool for creating dynamic and responsive user interfaces for web applications. With its reusable components and modular structure, React simplifies the development process and allows for more efficient code. By using the examples and tips outlined in this write-up, you can supercharge your web development with React and take your projects to the next level this write-up is strictly for Beginners who are interested on learning React.js, see you soon with more contents on React .
