holy grail of last.fm and spotify music data sites. i'd still say check the actual link but i've copy pasted most of the info n the links below

Spotify

Sites, apps and programs that use your Spotify account, Spotify API or both.

Spotify sites:

Obscurify: Tells you how unique you music taste is in compare to other Obscurify users. Also shows some recommendations. Mobile friendly.

Skiley: Web app to better manage your playlists and discover new music. This has so many functions and really the only thing I miss is search field for when you are managing playlists. You can take any playlist you "own" and order it by many different rules (track name, album name, artist name, BPM, etc.), or just randomly shuffle it (say bye to bad Spotify shuffle). You can also normalize it. For the other functions you don't even need the rights to edit the playlist. Those consists of splitting playlist, filtering out song by genre or year to new playlist, creating similar playlists or exporting it to CFG, CSV, JSON, TXT or XML.

You can also use it to discover music based on your taste and it has a stats section - data different from Last.fm.

Also, dark mode and mobile friendly.

Sort your music: Lets you sort your playlist by all kinds of different parameters such as BPM, artist, length and more. Similar to Skiley, but it works as an interactive table with songs from selected playlist.

Run BPM: Filters playlists based on parameters like BPM, Energy, etc. Great visualized with colorful sliders. Only downside - shows not even half of my playlists. Mobile friendly.

Fylter.in: Sort playlist by BMP, loudness, length, etc and export to Spotify

Spotify Charts: Daily worldwide charts from Spotify. Mobile friendly

Kaleidosync: Spotify visualizer. I would personally add epilepsy warning.

Duet: Darthmouth College project. Let's you compare your streaming data to other people. Only downside is, those people need to be using the site too, so you have to get your friends to log in. Mobile friendly.

Discover Quickly: Select any playlist and you will be welcomed with all the songs in a gridview. Hover over song to hear the best part. Click on song to dig deeper or save the song.

Dubolt: Helps you discover new music. Select an artist/song to view similar ones. Adjust result by using filters such as tempo, popularity, energy and others.

SongSliders: Sort your playlists, create new one, find new music. Also can save Discover weekly every monday.

Stats for Spotify: Shows you Top tracks and Top artists, lets you compare them to last visit. Data different from Last.fm. Mobile friendly

Record Player: This site is crazy. It's a Rube Goldberg Machine. You take a picture (any picture) Google Cloud Vision API will guess what it is. The site than takes Google's guess and use it to search Spotify giving you the first result to play. Mobile friendly.

Author of this site has to pay for the Google Cloud if the site gets more than 1000 requests a month! I assume this post is gonna blow up and the limit will be easily reached. Author suggests to remix the app and set it up with your own Google Cloud to avoid this. If your are able to do so, do it please. Or reach out to the author on Twitter and donate a little if you can.

Spotify Playlist Randomizer: Site to randomize order of the songs in playlist. There are 3 shuffling methods you can choose from. Mobile friendly.

Replayify: Another site showing you your Spotify data. Also lets you create a playlist based on preset rules that cannot be changed (Top 5 songs by Top 20 artists from selected time period/Top 50 songs from selected time period). UI is nice and clean. Mobile friendly, data different from Last.fm.

Visualify: Simpler replayify without the option to create playlists. Your result can be shared with others. Mobile friendly, data different from Last.fm.

The Church Of Koen: Collage generator tool to create collages sorted by color and turn any picture to collage. Works with Last.fm as well.

Playedmost: Site showing your Spotify data in nice grid view. Contains Top Artists, New Artists, Top Tracks and New Tracks. Data different from Last.fm, mobile friendly.

Playlist Manager: Select two (or more) playlists to see in a table view which songs are shared between them and which are only in one of them. You can add songs to playlists too.

Boil the Frog: Choose to artists and this site will create playlists that slowly transitions between one artist's style to the other.

SpotifyTV: Great tool for searching up music videos of songs in your library and playlists.

Spotify Dedup and Spotify Organizer: Both do the same - remove duplicates. Spotify Dedup is mobile friendly.

Smarter Playlists: It lets you build a complex program by assembling components to create new playlists. This seems like a very complex and powerful tool.

JBQX: Do you remember plug.dj? Well this is same thing, only using Spotify instead of YouTube as a source for music. You can join room and listen to music with other people, you all decide what will be playing, everyone can add a song to queue.

Spotify Buddy: Let's you listen together with other people. All can control what's playing, all can listen on their own devices or only one device can be playing. You don't need to have Spotify to control the queue! In my opinion it's great for parties as a wireless aux cord. Mobile friendly.

Opslagify: Shows how much space would one need to download all of their Spotify playlists as .mp3s.

Whisperify: Spotify game! Music quiz based on what you are listening to. Do you know your music? Mobile friendly.

Understanding Flutter Widgets: The Building Blocks of UI

Introduction

Flutter has rapidly emerged as one of the most popular frameworks for cross-platform app development. Known for its fast development cycle, beautiful UI components, and seamless performance, Flutter is widely adopted by developers worldwide. At the core of Flutter’s functionality lies its powerful widget-based architecture.

Whether you are building a simple application or a complex one, Flutter widgets play a crucial role in shaping the user interface (UI). In this article, we will explore what Flutter widgets are, their types, and why they are essential for app development. If you’re looking to master Flutter development, consider Flutter Training in Chennai, which provides hands-on experience in building UI with widgets.

What Are Flutter Widgets?

A widget in Flutter is a UI component that controls a part of the screen. Every UI element in a Flutter app, from a simple button to a complete screen layout, is made up of widgets. Flutter follows a widget tree structure, meaning widgets are nested within each other to create complex user interfaces.

Why Widgets Are Important in Flutter

Reusability – Widgets can be used multiple times across different parts of the app.

Customization – Widgets allow developers to create unique UI experiences.

Hot Reload – Changes made to widgets can be instantly reflected in the app.

Cross-Platform Development – Widgets enable seamless UI creation for Android, iOS, web, and desktop.

Types of Flutter Widgets

Flutter offers a rich set of widgets that developers use to build stunning interfaces. These widgets are primarily classified into two categories: Stateless Widgets and Stateful Widgets.

1. Stateless Widgets

Stateless widgets are immutable, meaning their properties do not change once they are created. They are used when the UI does not require updates based on user interaction or dynamic data changes.

Examples of Stateless Widgets:

Text Widget – Displays text on the screen.

Image Widget – Loads images from assets, network, or file.

Icon Widget – Displays icons from Flutter’s icon library.

RaisedButton – A simple button with elevation.

2. Stateful Widgets

Stateful widgets are dynamic and can change based on user interactions, API responses, or other factors. They maintain a state that can be modified during the app’s lifecycle.

Examples of Stateful Widgets:

TextField – Accepts user input dynamically.

Checkbox – Allows toggling between checked and unchecked states.

Slider – Provides a sliding control for setting values.

ListView – Displays a scrollable list of widgets.

Key Flutter Widget Categories

Apart from Stateless and Stateful widgets, Flutter provides several widget categories to enhance app development.

1. Layout Widgets

Layout widgets help structure the UI elements effectively.

Column – Arranges widgets vertically.

Row – Arranges widgets horizontally.

Stack – Overlaps widgets on top of each other.

Container – Provides padding, margins, and background properties.

2. Input Widgets

These widgets facilitate user interaction.

TextField – Enables text input.

DropdownButton – Displays a list of selectable options.

Switch – Toggles between on/off states.

3. Styling Widgets

Styling widgets enhance the visual appearance of the UI.

Padding – Adds space around a widget.

Align – Aligns widgets within their parent container.

DecoratedBox – Applies decorations like colors, gradients, and borders.

4. Scrolling Widgets

Scrolling widgets help manage content overflow.

ListView – Creates a scrollable list.

GridView – Arranges widgets in a grid format.

SingleChildScrollView – Allows a single widget to be scrollable.

5. Interactive Widgets

These widgets enable user interaction.

GestureDetector – Detects gestures like taps and swipes.

InkWell – Provides visual feedback on touch.

FloatingActionButton – A button that performs primary app actions.

How Flutter Widgets Improve UI Development

1. Faster Development with Hot Reload

One of the biggest advantages of Flutter’s widget system is Hot Reload, which allows developers to instantly see the changes they make without restarting the app.

2. Consistent UI Across Platforms

Flutter widgets ensure a native-like UI experience across Android, iOS, web, and desktop platforms, making cross-platform development seamless.

3. Customization and Theming

Flutter allows extensive customization of widgets through properties like colors, shapes, and animations. Themingenables developers to apply a consistent design across the app.

Future of Flutter Widgets

As Flutter continues to evolve, its widget ecosystem is expanding with new features and optimizations. Some trends in Flutter widget development include:

Adaptive Widgets – Widgets that adjust automatically based on the platform.

Flutter Web Widgets – Enhancing Flutter’s web development capabilities.

Difference between ASP.NET Web Forms and ASP.NET MVC.

ASP.NET Web Forms and ASP.NET MVC are two different frameworks for building web applications within the ASP.NET ecosystem. They cater to different development needs and philosophies. Here’s a detailed comparison of the two:

ASP.NET Web Forms

Overview:

Introduced with the initial release of ASP.NET.

Based on a component-based and event-driven programming model.

Designed to abstract much of the complexity of web development by mimicking a Windows Forms application.

Key Features:

Event-Driven Model: Web Forms use a page and control lifecycle with events similar to desktop application development.

ViewState: Automatically maintains the state of the controls between requests, simplifying the development of interactive web pages.

Server Controls: Rich set of server controls (e.g., GridView, DataList) that encapsulate HTML and behavior, reducing the need for manual HTML and JavaScript.

Code-Behind: Separates the HTML markup (ASPX file) from the server-side logic (code-behind file, usually in C# or VB.NET).

Rapid Development: Suited for quick development with minimal coding for UI-heavy applications.

Strengths:

Ease of Use: Easier to learn for developers with a desktop application background.

Rapid Application Development: Suitable for developing applications quickly with minimal effort.

Rich Controls: Provides a wide range of built-in controls for common tasks.

Weaknesses:

ViewState Overhead: ViewState can become large and affect performance, especially for pages with many controls.

Less Control Over HTML: Less flexibility and control over the rendered HTML and client-side behavior.

Tight Coupling: Tends to produce tightly coupled code that can be harder to maintain and test.

ASP.NET MVC

Overview:

Introduced in 2009 to provide a more flexible and testable framework.

Based on the Model-View-Controller (MVC) design pattern, which separates the application into three main components: Model, View, and Controller.

Key Features:

Separation of Concerns: Clear separation between business logic (Model), UI (View), and input handling (Controller), promoting cleaner code architecture.

Testability: Easier to unit test due to the separation of concerns and use of interfaces.

Full Control Over HTML: Allows complete control over the rendered HTML and client-side behavior.

Routing: Uses a powerful routing engine to map URLs to controller actions, providing clean and SEO-friendly URLs.

Extensibility: Highly extensible, allowing developers to customize or replace framework components as needed.

Strengths:

Fine-Grained Control: Provides detailed control over HTML, CSS, and JavaScript, facilitating the creation of responsive and interactive web applications.

Testability: Easier to write unit tests for MVC applications.

SEO-Friendly: Clean URLs and better control over HTML output make it easier to optimize for search engines.

Scalability: Better suited for large and complex applications due to its structured architecture.

Weaknesses:

Learning Curve: Steeper learning curve, especially for developers not familiar with the MVC pattern.

More Code: Typically requires more code and effort to achieve the same functionality compared to Web Forms.

Key Differences

Programming Model:

Web Forms: Event-driven, uses server controls, and maintains state through ViewState.

MVC: Pattern-based, uses controllers and views with a clear separation of concerns.

Control Over HTML:

Web Forms: Abstracts HTML and client-side details using server controls.

MVC: Gives developers complete control over HTML and client-side behavior.

State Management:

Web Forms: Automatically manages state through ViewState.

MVC: Stateless by default, requiring developers to manage state manually.

Testability:

Web Forms: Harder to unit test due to tightly coupled code.

MVC: Easier to unit test due to separation of concerns and use of interfaces.

Development Approach:

Web Forms: Rapid application development with less code for UI-heavy applications.

MVC: More structured and maintainable approach, suitable for complex applications.

Conclusion

Both ASP.NET Web Forms and ASP.NET MVC have their own strengths and are suited for different types of applications. Web Forms are ideal for rapid development and applications that benefit from an event-driven model. In contrast, ASP.NET MVC is better suited for applications that require fine-grained control over HTML, improved testability, and a scalable architecture. Choosing between the two depends on the specific needs and constraints of the project, as well as the familiarity and preference of the development team.

How To Scrape Walmart for Product Information Using Python

In the ever-expanding world of e-commerce, Walmart is one of the largest retailers, offering a wide variety of products across numerous categories. If you're a data enthusiast, researcher, or business owner, you might find it useful to scrape Walmart for product information such as prices, product descriptions, and reviews. In this blog post, I'll guide you through the process of scraping Walmart's website using Python, covering the tools and libraries you'll need as well as the code to get started.

Why Scrape Walmart?

There are several reasons you might want to scrape Walmart's website:

Market research: Analyze competitor prices and product offerings.

Data analysis: Study trends in consumer preferences and purchasing habits.

Product monitoring: Track changes in product availability and prices over time.

Business insights: Understand what products are most popular and how they are being priced.

Tools and Libraries

To get started with scraping Walmart's website, you'll need the following tools and libraries:

Python: The primary programming language we'll use for this task.

Requests: A Python library for making HTTP requests.

BeautifulSoup: A Python library for parsing HTML and XML documents.

Pandas: A data manipulation library to organize and analyze the scraped data.

First, install the necessary libraries:

shell

Copy code

pip install requests beautifulsoup4 pandas

How to Scrape Walmart

Let's dive into the process of scraping Walmart's website. We'll focus on scraping product information such as title, price, and description.

1. Import Libraries

First, import the necessary libraries:

python

Copy code

import requests from bs4 import BeautifulSoup import pandas as pd

2. Define the URL

You need to define the URL of the Walmart product page you want to scrape. For this example, we'll use a sample URL:

python

Copy code

url = "https://www.walmart.com/search/?query=laptop"

You can replace the URL with the one you want to scrape.

3. Send a Request and Parse the HTML

Next, send an HTTP GET request to the URL and parse the HTML content using BeautifulSoup:

python

Copy code

response = requests.get(url) soup = BeautifulSoup(response.text, "html.parser")

4. Extract Product Information

Now, let's extract the product information from the HTML content. We will focus on extracting product titles, prices, and descriptions.

Here's an example of how to do it:

python

Copy code

# Create lists to store the scraped data product_titles = [] product_prices = [] product_descriptions = [] # Find the product containers on the page products = soup.find_all("div", class_="search-result-gridview-item") # Loop through each product container and extract the data for product in products: # Extract the title title = product.find("a", class_="product-title-link").text.strip() product_titles.append(title) # Extract the price price = product.find("span", class_="price-main-block").find("span", class_="visuallyhidden").text.strip() product_prices.append(price) # Extract the description description = product.find("span", class_="price-characteristic").text.strip() if product.find("span", class_="price-characteristic") else "N/A" product_descriptions.append(description) # Create a DataFrame to store the data data = { "Product Title": product_titles, "Price": product_prices, "Description": product_descriptions } df = pd.DataFrame(data) # Display the DataFrame print(df)

In the code above, we loop through each product container and extract the title, price, and description of each product. The data is stored in lists and then converted into a Pandas DataFrame for easy data manipulation and analysis.

5. Save the Data

Finally, you can save the extracted data to a CSV file or any other desired format:

python

Copy code

df.to_csv("walmart_products.csv", index=False)

Conclusion

Scraping Walmart for product information can provide valuable insights for market research, data analysis, and more. By using Python libraries such as Requests, BeautifulSoup, and Pandas, you can extract data efficiently and save it for further analysis. Remember to use this information responsibly and abide by Walmart's terms of service and scraping policies.

Unveiling Flutter's Widget Wonderland: A Comprehensive Guide to Mastering the Heartbeat of App Development

The process of creating cross-platform applications has been completely transformed by Flutter, Google's open-source UI software development framework. Flutter's vast range of widgets is the foundation for its adaptability and strong user interface. In this post, we explore the world of Flutter widgets, including their importance, applications, and ways to meet various development demands.

Developers who are keen to fully utilize Flutter widgets, regardless of skill level, should read this post. More experienced developers will learn advanced approaches and best practices for building effective and aesthetically pleasing user interfaces (UIs), while beginners will learn the basics of widgets.

Use Cases:

The fundamental components of Flutter applications are Flutter widgets, which give developers the ability to design a smooth and interesting user interface. The following are some important use cases that demonstrate how versatile Flutter widgets are:

1. Customized UI Components:

With Flutter widgets, developers can create one-of-a-kind, interactive user interfaces. Flutter widgets provide you the freedom to modify any part of the user interface (UI) to satisfy particular design specifications, whether it's a personalized button, a modern navigation bar, or an animated card.

2. Responsive Layouts:

The widget system in Flutter is excellent at producing responsive layouts that change with the size and orientation of the screen. Because of this, it's perfect for creating apps that must function reliably on a range of gadgets, including tablets and smartphones.

3. Animation and Motion:

Animations are easy to implement with the help of Flutter widgets. The user experience can be improved by developers giving their applications a dynamic touch, ranging from straightforward fade-ins to intricate physics-based animations.

4. State Management:

Flutter widgets are essential for controlling an application's state. Constructing reliable and effective Flutter applications requires an understanding of stateful and stateless widgets.

The foundation of Flutter development are widgets, which offer an extensive toolkit for creating stunning and responsive user interfaces. Flutter's hierarchical UI component structure, known as the widget tree, enables developers to assemble basic building blocks into intricate user interfaces.

The reusability of Flutter widgets is one of their main advantages. Developers can create modular components that can be reused across multiple parts of an application or even across multiple projects. This not only saves development time but also ensures design and functionality consistency.

Custom button widget:

Flutter widgets are excellent for creating intricate user interfaces. Developers have a wide range of options available to them, ranging from basic layout widgets like Column and Container to more specialized widgets like ListView and GridView. The "hot reload" function of Flutter expedites the development process even more by enabling developers to immediately see the effects of their modifications.

But widgets in Flutter aren't just for the user interface. They are also essential in managing an application's state. When the UI needs to change dynamically, stateful widgets with mutable state are used. Stateless widgets, on the other hand, are ideal for UI elements that remain static.

The more Flutter development you do, the more crucial it is to grasp how to use and manipulate widgets. Understanding Flutter widgets is essential whether you're creating a productivity tool, social media platform, or slick e-commerce application.

As we wrap up our look at Flutter widgets, we'd like to thank the vibrant Flutter community and the developers who continue to push the boundaries of what's possible with this powerful toolkit. Remember that the learning process for Flutter widgets is ongoing, and the possibilities are endless.

In conclusion, Flutter widgets are the secret sauce behind Flutter's success in delivering visually appealing and performant cross-platform applications. Whether you're a beginner taking your first steps into Flutter development or an experienced developer looking to enhance your UI-building skills, mastering Flutter widgets is a crucial step in your journey. Embrace the flexibility, reusability, and power that Flutter widgets bring to your applications, and unlock a world of possibilities in crafting exceptional user experiences.
