After a long time, Bootstrap v5.2.0-beta1 was released last week. This version of bootstrap is the biggest release update till now and is being billed as the framework’s most significant release since Bootstrap 5.0 two years ago. This version features a redesigned document, all components of CSS Variable, responsive offcanvas, new helpers and utilities, improved buttons and inputs, and many underlying improvements. Builders are offering CSS variables for all components and new helpers and utilities in the latest planned upgrade to the Bootstrap web development framework. Let’s look at some major changes in Bootstrap 5.2.0.

Redesigned documents

The development team rewrites the whole home page, To better show Bootstrap All functions of. Changes include simplifying the navigation bar, Cancel sub navigation, and changing the sidebar to always show links to each page to improve discoverability. It also shows Updated Quick Start Guide. It is now through CDN Use Bootstrap Step-by-step guide.

The updated navigation bar also has a new version selector, which starts from v5.2.0 And higher. On any page, click versions and view options to navigate to previous minor versions of the same page. When a page does not exist in the old version, you will see the disabled version in the drop-down list. Official expression, it currently has no plans to link pages across major versions.

Document search is now powered by the latest version of Algolia DocSearch Provide support , Brings improved design. You can even display your recent searches.

Design adjustment

In order to cooperate with the redesign of documents, the development team made some detailed border radius updates for the buttons and input methods. Components now have improved theming and CSS variables for real-time customization. Color-mode support will be added soon, starting with dark mode.

It is easier to modify custom components. Here are two examples:

New.text-bg-color helpers have been added. Developers can now use the.text-bg-* helpers to set background colour with contrasting foreground colour instead of setting individual.text-* and.bg-* utilities.

Font-weight utilities have been expanded to include.fw-semibold for semibold fonts.

Component CSS variables

With this release, all components now include CSS variables to enable real-time customization, easier theming, and (soon) color mode support starting with dark mode. Every component page has been updated to include a reference guide of the relevant CSS variables.

--#{$prefix}btn-padding-x: #{$btn-padding-x};
--#{$prefix}btn-padding-y: #{$btn-padding-y};
--#{$prefix}btn-font-family: #{$btn-font-family};
@include rfs($btn-font-size, --#{$prefix}btn-font-size);
--#{$prefix}btn-font-weight: #{$btn-font-weight};
--#{$prefix}btn-line-height: #{$btn-line-height};
--#{$prefix}btn-color: #{$body-color};
--#{$prefix}btn-bg: transparent;
--#{$prefix}btn-border-width: #{$btn-border-width};
--#{$prefix}btn-border-color: transparent;
--#{$prefix}btn-border-radius: #{$btn-border-radius};
--#{$prefix}btn-box-shadow: #{$btn-box-shadow};
--#{$prefix}btn-disabled-opacity: #{$btn-disabled-opacity};
--#{$prefix}btn-focus-box-shadow: 0 0 0 #{$btn-focus-width} rgba(var(--#{$prefix}btn-focus-shadow-rgb), .5);

Values for virtually every CSS variables are assigned via Sass variable, so customization via CSS and Sass are both well supported. Also included for several components are examples of customizing via CSS variables.

New _maps.scss

Bootstrap v5.2.0-beta1 introduces a new Sass file with _maps.scss that pulls out several Sass maps from _variables.scss to fix an issue where updates to an original map were not applied to secondary maps that extend it. It’s not ideal, but it resolves a longstanding issue for folks when working with customized maps.

For example, updates to $theme-colors were not being applied to other maps that relied on $theme-colors (like the $utilities-colors and more), which created broken customization workflows. To summarize the problem, Sass has a limitation where once a default variable or map has been used, it cannot be updated. There’s a similar shortcoming with CSS variables when they’re used to compose other CSS variables.

This is also why variable customizations in Bootstrap have to come after @import “functions”;, but before @import “variables”; and the rest of the import stack. The same applies to Sass maps—you must override the defaults before they get used. The following maps have been moved to the new _maps.scss:

  • $theme-colors-rgb
  • $utilities-colors
  • $utilities-text
  • $utilities-text-colors
  • $utilities-bg
  • $utilities-bg-colors
  • $negative-spacers
  • $gutters

New helpers and utilities

  • Added a new .text-bg-{color}helpers. Now you can use .text-bg-* helpers To set the background color with a contrasting foreground color, Instead of setting up a separate .text-* and .bg-* utilities.
  • Expanded font-weightutilities, Include for semibold fonts Of .fw-semibold.
  • Expanded border-radius utilities , Includes two new sizes :.rounded-4 and .rounded-5, To provide more options.

Responsive offcanvas

Offcanvas component now has responsive variations. The original .offcanvas class remains unchanged—it hides content across all viewports. To make it responsive, change that .offcanvas class to any .offcanvas-{sm|md|lg|xl|xxl} class.

Coming soon: Dark mode!

Much of the work they have done in v5.2.0-beta1 has been in support of adding dark mode to Bootstrap. Yes, it’s finally coming in their next minor release!

They have also mentioned “We’re adding tons of new global CSS variables, cleaning up docs styles, and better supporting overall customization”.

Coming In V5.3.0

There’s lots to look forward to in their next minor release, though they’ll likely have some bug fixes along the way.

  • Dark mode! As mentioned above, they’re actively working to bring more nuanced color options and color modes to Bootstrap.
  • An attribute toggle plugin to programmatically toggle classes and attributes by only writing HTML.
  • CSS variables for forms!
  • CSS variables for forms!
  • Sticky headers for tables
  • Mixins and functions for modifying the utilities API.
  • An option for “always floating” floating forms.

Conclusion

More advancements in this direction are expected as Version 5 development progresses. Version 5.2.0 includes investments in helpers and utilities to make it easier to modify custom components. The project website provides access to Bootstrap v5.2.0-beta1. You can Head to https://getbootstrap.com to get the latest release. Hopefully the next update will be beneficial to those who have been wanting the above mentioned features.

It’s time again for a Flutter stable release and they are incredibly proud to announce Flutter 3! Only three months ago, they announced Flutter support for Windows. Now they have announced that Flutter will be stable for macOS and Linux, in addition to Windows!

It is said that Flutter has merged 5248 pull requests! They have announced several things as part of this release, including the update on Flutter’s support for macOS and Linux, significant performance improvements, mobile and web updates — and much more! In addition, they have announced about the reduction in support for older versions of Windows, and a short list of breaking changes. In today’s discussion we will deep dive into the latest Flutter release. So, let’s get down to business!

Flutter 3 brought joy to desktop platforms

With the release of Flutter 3, the labor of adding platforms is complete as developers on the stable channel can now build apps for macOS as well as Linux devices and expect first-class support. For Linux, this effort has been assisted by Canonical, developers of Ubuntu, who have been using Flutter to create core experiences within Ubuntu, including parts of the setup flow. Meanwhile, part of supporting macOS is that both Flutter and the underlying Dart programming language now have native support for Apple Silicon. Better yet, you can ship Flutter apps in the Universal Binary format, allowing them to run effectively on both Apple Silicon and Intel based Macs. This Apple Silicon support also extends to developers, with the Flutter and Dart SDKs both now ready to run on the latest generations of Mac Linux and macOS have reached stable and these following features have been included:

macOS system menu bar

You can now create platform-rendered menu bars on macOS using the PlatformMenuBar widget, which supports insertion of platform-only menus, and control over what appears in the macOS application menus.

Full support for international text input

International text input, including for languages that make use of text input method editors (IMEs) such as Chinese, Japanese, and Korean is fully-supported on all three desktop platforms, including third-party input methods such as Sogou and Google Japanese Input.

Accessibility

Flutter has included new accessibility services. Windows, macOS, and Linux all of them support this accessibility services such as screen-readers, accessible navigation, and inverted colors.

Universal binaries by default on macOS

As of Flutter 3, Flutter macOS desktop apps are built as universal binaries, with native support for both existing Intel-based Macs and Apple’s latest Apple Silicon devices.

Deprecating Windows 7/8 for development

With this release, they have been raising the recommended Windows version for development to Windows 10. While they aren’t blocking development on older versions (Windows 7, Windows 8, Windows 8.1), these versions are no longer supported by Microsoft and they will provide limited testing on these releases. But while they promised to offer ‘best effort’ support for older versions, they encouraged us to upgrade.

Mobile updates

Udates to mobile platforms includes the following:

Foldable phone support

The Flutter 3 release supports foldable mobile devices. In a collaboration spearheaded by Microsoft, new features and widgets will allow you to create dynamic and delightful experiences on foldable devices.

As part of this work, MediaQuery now contains a list of DisplayFeatures, describing the bounds and states of device elements like hinges, folds, and cutouts. Additionally, the DisplayFeatureSubScreen widget now positions its child widget without overlapping the bounds of DisplayFeatures, and has already been integrated with the framework’s default dialogs and pop-ups, making Flutter aware and responsive to these elements out of the box.

iOS variable refresh rate support

Flutter now supports variable refresh rate on iOS devices with ProMotion displays, including iPhone 13 Pro and iPad Pro. On these devices, Flutter apps can render at refresh rates reaching 120 hz, which were previously limited to 60 hz. This results in a smoother experience during fast animations such as scrolling. See flutter.dev/go/variable-refresh-rate for more details.

Simplified iOS releases

They have added new options to the flutter build ipa command to simplify releasing iOS apps. When you’re ready to distribute to TestFlight or the App Store, run flutter build ipa to build an Xcode archive (.xcarchive file) and an app bundle (.ipa file). You can optionally add –export-method ad-hoc, –export-method development, or –export-method enterprise. Once the app bundle is built, upload it to Apple through the Apple Transport macOS app or on the command line using xcrun altool (run man altool for App Store Connect API key authentication instructions). After uploading, your app is available for release to TestFlight or the App Store. After setting up your initial Xcode project settings, such as display name and app icon, you no longer need to open Xcode to release your app.

Web updates

Updates for web apps include the following:

Image decoding

Flutter web now automatically detects and uses the ImageDecoder API in browsers that support it. As of today, most Chromium-based browsers (Chrome, Edge, Opera, Samsung Browser, and more) have added this API.

The new API decodes images asynchronously off the main thread using the browser’s built-in image codecs. This speeds up image decoding by 2x, and it never blocks the main thread, removing all jank that was previously caused by images.

Web app lifecycles

The new lifecycle API for Flutter web apps gives you the flexibility to control the bootstrap process of your Flutter app from the hosting HTML page, and helps Lighthouse analyze the performance of your app.

Conclusion

Now that Flutter 3 has reached the six major platforms — Android, iOS, Web, Windows, macOS, and Linux — the big question some may have is “what’s next?” For Google, creating support for those platforms was intended to give Flutter a strong foundation to build upon. Now that the foundation has been laid, Google will continue to build upon it in two key avenues: improving developer productivity and expanding what Flutter can do.

React 18 was released in March 2022. Officially, React 18 is now ready to use! This release focuses on performance improvements and updating the rendering engine. React 18 sets the foundation for concurrent rendering APIs that future React features will be built on top of.

In my opinion, the latest feature that revolutionized the React Ecosystem was React Hooks, introduced in React 16.8 back in 2019. Since then, we have seen many versions being released. But without any major changes, what will happen in React 18? In this tutorial, we will have a quick look at the features released in React 18, and explain a few major concepts such as concurrent rendering, automatic batching, and transitions.

New Features

Automatic Batching

React 18 features automatic batching. To understand batching, let’s consider the example of grocery shopping from the same React Working Group discussion.

Let’s say that you are making pasta for dinner. If you were to optimize your grocery trip, you would create a list of all the ingredients that you need to buy, make a trip to the grocery store, and get all your ingredients in one trip. This is batching.

Without batching, you would start cooking, find out you need an ingredient, go to the grocery store and buy the ingredient. When you come back and continue cooking, you’ll find out you need another ingredient, you’ll then go to the grocery store again to buy that ingredient

In React, batching helps to reduce the number of re-renders that happen when a state changes, when you call setState. With this new exciting feature, React will combine multiple setState() calls into a single re-render to improve performance. Before this, if we had multiple setState() inside of a setTimeout(), React will re-render for every state update which sometimes causes performance issues if we have larger components. Previously, React batched state updates in event handlers.

You may already be familiar with this. This feature was available in React 17, but now it comes out of the box.

// React 17
  setTimeout(() => {
    setCount(c => c + 1);
    setFlag(f => !f);
    // The component will be rendered twice.
  }, 1000);


// React 18
  setTimeout(() => {
    setCount(c => c + 1);
    setFlag(f => !f);
    // The component will be rendered only once.
  }, 1000);

Transitions

This new feature lets the dev split the state update into two categories: urgent and low priority.

Transitions can be used to mark UI updates that do not need urgent resources for updating. For some actions, like selecting in a dropdown or updating an input, you want the action to respond immediately, so now we could distinguish between an urgent update and a non-urgent one. These non-urgent updates are called transitions. By marking non-urgent UI updates as “transitions”, React will know which updates to prioritize. This makes it easier to optimize rendering and get rid of stale rendering.

Updates wrapped in startTransition are handled as non-urgent and will be interrupted if more urgent updates like clicks or keypresses come in.

import { startTransition } from 'react';

// Updating state with urgent priority
setInputValue(input);

// Inside startTransition the updates won't be urgent
// and can be interrupted
startTransition(() => {
  setSearchQuery(input);
});

New Suspense Features

Finally, we will have Suspense on the server. In the server-rendered apps, we will have only one Suspense API.

In a client-rendered app, you load the HTML of your page from the server along with all the JavaScript that is needed to run the page and make it interactive.

If, however, the JavaScript bundle is huge, or you have a slow connection, this process can take a long time and the user will be waiting for the page to become interactive, or to see meaningful content. For optimizing the user experience and avoiding the user having to sit on a blank screen, we can use server rendering.

Server rendering is a technique where you render the HTML output of your React components on the server and send HTML from the server. This lets the user view some UI while JS bundles are loading and before the app becomes interactive. Server rendering further enhances the user experience of loading the page and reducing the time to interact.

Before React 18, this part was often the bottleneck of the app and would increase the time it took to render the component. Now React 18 adds support for Suspense on the server. With the help of suspense, you can wrap a slow part of your app within the Suspense component, telling React to delay the loading of the slow component. This can also be used to specify a loading state that can be shown while it’s loading.

Strict mode

Strict mode in React 18 will simulate mounting, unmounting, and re-mounting the component with a previous state. This sets the ground for a reusable state in the future where React can immediately mount a previous screen by remounting trees using the same component state before unmounting.

Strict mode will ensure components are resilient to the effects of being mounted and unmounted multiple times.

IE11 no longer supported

IE11 is no longer supported since React 18. If your app needs to continue bringing support to IE11, you will need to stay at React 17. x.

Conclusion

Some cool features like Automatic Batching or Adding Suspense should improve the performance of React in the latest release. I’m really excited to see how these new features will perform in a real-life app, but they look more than promising. In a summary, React 18 sets the foundation for future releases and focuses on improving the user experience.

Upgrading to React 18 should be straightforward and your existing code should not break after the update. The upgrade process should not take more than an afternoon.

Google Play is officially launching its own version of privacy-related “nutrition labels” for apps. They are introducing a new section in Play Store listings that requires developers to describe the data their app gathers and how they will use it. This will be like a privacy label giving users crucial information at a glance, which should be enough to help them decide if they would like to proceed with the installation.

According to Google, users want to understand the purpose of the apps to collect their data and whether the developer is sharing it with third parties, as well as how developers protect that data. The new section is titled ‘Data safety’ and will appear alongside the usual sections like ‘About this app’ and ‘Ratings and reviews’. It will function as a privacy label, providing users with key information shortly, which should be enough to let them decide whether or not to install the app. Not only will developers declare what data they collect, but also what data they share with third parties, essentially disclosing the purpose behind the collection. Google showed off its version last year but is only beginning to roll it out this week. According to them, it will begin to roll out the new Google Play Data safety section to users on a gradual basis so that Android users won’t see this new section immediately but over the next couple of weeks.

Suzanne Frey, Vice President of Product, Android Security, and Privacy at Google said in a blog post, “You alone are responsible for making complete and accurate declarations in your app’s store listing on Google Play,”

Failure to do so would lead to policy violations, leading to the suspension of the app in the Google Play Store.

“Google Play reviews apps across all policy requirements; however, we cannot make determinations on behalf of the developers of how they handle user data. Only you possess all the information required to complete the Data safety form”. “When Google becomes aware of a discrepancy between your app behavior and your declaration, we may take appropriate action, including enforcement action,” explained Frey.

If the user wants to learn more about a particular entry, tapping on the corresponding item will collapse the menu to reveal more information on what is collected or shared. The third pillar of the Data Safety section will be the app’s security practices, which describe the security mechanisms employed to protect the collected data, like the MASVS standard. This third section also clarifies whether users are given the option to ask for the deletion of their data at any time. And finally, Data Safety will specify if the app follows Google Play Families Policy, which is geared toward children’s protection.

Developers can begin declaring how collected data is used starting today, with the deadline to complete their submissions being July 20th, 2022.

Google told that developers would provide this information themselves, which Google will not confirm. However, if it is discovered that a developer has misrepresented their data use disclosures, they will be required to fix the provided information. Google is essentially relying on developers, to be honest in the information they provide to users in this section.

While Google’s move is beneficial to Android users, a similar feature called ‘Privacy Nutrition Labels’ was already introduced by Apple in 2020. Apple also released a similar feature as part of numerous privacy-enhancing features in last year’s iOS 14. This is another case where competition in the mobile OS space has brought positive developments, giving users more insight and control over how their data are handled by the various software that runs on their smartphones.

While both sets of labels focus on informing users about how apps collect and manage data and user privacy, there are some key differences. Apple’s labels largely focus on what data is being collected, including data used for tracking purposes, and on informing the user what’s linked to them. Google’s labels, meanwhile, put a bigger focus on whether you can trust the data that’s collected is being handled responsibly by allowing developers to disclose if they follow best practices around data security. The labels also give Android developers a way to make their case as to why they collect the data directly on the label, so users can understand how the data is used — for app functionality, personalization, etc. — to help inform the user’s decision to download the app. They can also see if the data collection is required or optional.

Up until now, Android apps on the Play Store had to list a link to their Privacy Policy under the “Additional Information” section and provide a contact email. Since this privacy policy is hosted on an external location, it’s subject to modifications, might be vague, may not disclose all the crucial details about data collection and protection, and may even lead to a broken link.

This Data Safety gives users a clear understanding of what happens with their data without requiring them to spend time digging into sections, while it also empowers Google with enforcement. Moreover, since reading large texts of legal jargon isn’t exactly what users look forward to when browsing the Google Play Store for new apps, almost nobody checks these.

App privacy labels have already been accused of being an unreliable source of information following their launch on the App Store. According to a report by The Washington Post last year, many of the labels they reviewed in a spot-check provided false information. For instance, apps claiming they collected no data were actually found to be doing the opposite — collecting it and sharing it. Google is confident about the step it is taking and also claims to be honest about this Data Safety feature they are bringing.

With a large number of scam apps, malware, and usury apps found on Google Play, this new Data Safety section will not only be useful for Android users but also allow Google to find policy violators more quickly. For more information on the new system, what it includes, and how it works, check out Google’s support page.

Apr 30

Two years after Epic Games revealed Unreal Engine 5 with a gorgeous tech demo, the next-gen game engine is officially available, Epic Games announced on Tuesday. The latest edition of the benchmark game development engine touts a new “fully dynamic global illumination” tool, plus a geometry system that allows creators to build games with “massive amounts of geometric detail.” After being available in Early Access since May 2021 and Preview since February 2022, Epic Games has now released Unreal Engine 5 which will no doubt go on to power some of the biggest upcoming releases.

Epic announced Unreal Engine 5’s launch with a Twitch and YouTube live stream showing high-performance visuals and real-time rendering. Unreal Engine 5 will also use a new World Partition system that, Epic says, “changes how levels are managed and streamed,” by dividing up the game world into a grid and streaming only its necessary cells.

Unreal Engine 5 is Epic’s latest in the line of game engines available to game developers big and small. While the release of a new game engine isn’t typically news that excites folks until video games start getting made with them, Epic first revealed Unreal Engine 5 with a blockbuster tech demo Called Lumen in the Land of Nanite, the tech demo was made to specifically demonstrate two of the marquis features of Unreal Engine 5. Lumen is a dynamic illumination tool where the light adapts to the world naturally and easily.

“With this release, we aim to empower both large and small teams to really push the boundaries of what’s possible, visually and interactively. UE5 will enable you to realize next-generation real-time 3D content and experiences with greater freedom, fidelity, and flexibility than ever before.” — Epic Games.

Epic also said that developers would be able to continue using “workflows supported in UE 4.27” but get access to the redesigned Unreal Editor, better performance, improved path tracing, and the list goes on.

A “preview” version of Unreal Engine 5 has been available for a while now, but on Tuesday it officially took Unreal Engine 4’s place as the current Unreal version: Unreal Engine 5 is out now. We can expect new Unreal-based games to use the latest engine, as well as many in-progress games, such as Stalker 2, the next Tomb Raider (also announced that day), and games from developers such as Remedy, Obsidian, and Ninja Theory. The video embedded above is a new UE5 tech demo compilation from Gears of War studio The Coalition.

Two new starter samples have also been made for developers: Lyra Starter Game, City Sample

Lyra Starter Game

Lyra Starter Game is a sample gameplay project built alongside Unreal Engine 5 development to serve as an excellent starting point for creating new games, as well as a hands-on learning resource. We plan to continue to upgrade this living project with future releases to demonstrate our latest best practices.

City Sample

The City Sample is a free downloadable sample project that reveals how the city scene from The Matrix Awakens: An Unreal Engine 5 Experience was built. The project—which consists of a complete city with buildings, vehicles, and crowds of MetaHuman characters—demonstrates how we used new and improved systems in Unreal Engine 5 to create the experience.

You will also find plenty of Linux and Vulkan improvements for Unreal Engine 5 including: Nanite and Lumen (with software ray tracing only) on Linux, the Unreal Build Tool was also upgraded to support Clang’s sanitizers for Linux (and Android), Vulkan and Linux support was also added to their “GameplayMediaEncoder”, compliant 64-bit image atomics in Vulkan that fixes all validation issues with 64-bit atomics and allows the use of RADV driver (AMD + Linux) for Nanite and Lumen, multiple crashes were solved for Linux. There are some features specific to open-world games, too, which may be useful for CD Projekt Red’s new Witcher game; the studio announced last month that it’s switching to Unreal Engine 5. One of those features is World Partition, which handles the on-the-fly loading and unloading of open worlds as players move through them. Adoption of UE5 will mean different things for different studios, but the big themes are workflow streamlining and high-fidelity geometry and lighting. The 2020 Unreal Engine 5 reveals video leads with its new “micro polygon geometry system,” Nanite, and its “global illumination solution,” Lumen. With Nanite and Lumen, Epic says that developers can import film-quality 3D assets with “massive amounts of geometric detail” and set up dynamic lights without worrying about certain complex technical steps, especially those to do with optimization. The engine handles the ‘making it run on our PCs’ part, or at least more of it.

UE5 also includes new modeling and animation tools, “a fundamentally new way of making audio,” and other features meant to simplify the work of game development and keep as much of it as possible in the Unreal Engine development environment. In fact, using Epic’s Quixel Megascans (super detailed environment models) and MetaHumans (realistic, customizable human models), which are free to use in Unreal Engine projects, you can make a playable game without ever minimizing the UE5 dev kit.

Another interesting fact about Unreal Engine 5 is, like the previous version, Unreal Engine 5 is free to download and use; Epic doesn’t collect royalties on indie games until they’ve earned over $1 million in revenue. It is now available on the Epic Games launcher. If you already had the UE5 preview version installed, it’s about a 5 GB update.

Last week, Browserling, world’s leading cross-browser testing company, announced that they’re launching a network of online developer tools that offer simple, free and easy to use utilities for programmers.

They’re starting with four sites in the network and will be expanding their network to thirty websites. Each site in their network covers one specific programming category. There are no ads, popups, blinking download buttons, or other garbage. Just useful utilities that work in your browser. All utilities are created by skilled software engineers and they just do the right thing.

Let’s review first four sites in the network.

#1 Online JSON Tools


Online JSON Tools for Programmers
Online JSON Tools

Online JSON Tools is the first website in Browserling’s online tools network. It’s all about working with JSON data structures and objects. You can perform all the most common operations, such as minify JSON, beautify JSON, validate JSON, escape and unescape JSON, convert JSON to XML, CSV, TSV, and YAML, and encode/decode JSON to/from base64 encoding.

Soon you’ll also be able to syntax highlight JSON and edit it in your browser, display a summary of JSON object statistics, flatten JSON objects, convert JSON to HTML tables and LaTeX tables, compare two JSON structures, and encode and decode JSON to and from percent-encoding.

#2 Online String Tools


Online String Tools for Programmers
Online STRING Tools

Online String Tools is the second and the largest website in Browserling’s online tools network. It’s all about working with strings. There are over 100 tools in this website and many more are getting added every week. Online String Tools allow you to encode, decode, convert, filter, replace, and generate strings right in your browser.

For example, you can URL-encode and URL-decode strings, HTML-encode and HTML-decode strings, base64-encode and base64-decode strings, slash-escape and slash-unescape strings, generate random strings and generate strings from regular expressions. You can split strings, join strings, convert strings to binary and ASCII codes. And much more.

The upcoming tools in Online String Tools website will be a multi-replace string tool that allows you to replace multiple strings at once, online diffing tool that will show changes between two strings, Levenshtein distance calculator, which will also let you view the distance visually, a string rewriting system, Zalgo string generator, and a string typo generator.

#3 Online CSV Tools

Microsoft Popfly is a set of online visual tools for novice programmers and end-users to build Web pages, applications and games.  This was Microsoft’s attempt to bring programming to the masses, similar to Hypercard on the Macintosh, or the original Visual Basic on Windows before it became a real (complicated) object-oriented language under .NET.

But this fly lived for only two years.  Microsoft has just announced that on August 24, 2009, the Popfly service will be discontinued and all sites, references, and resources will be taken down.  At that time, access to your Popfly account, including any games and mashups that you have created, will be discontinued.
