Introduction to AngularAngularJS is an open-source web framework as a first version. Google backs AngularJS. AngularJS is the first front-end framework based on the MVC design pattern. This allows the feature called two-way binding, which enables it to reflect changes continuously on a page. Also, AngularJS provides features such as Dependency Injection, ready-to-use templates, and testing. It allows the development of Single Page Applications with neat and clean code. These features make AngularJS unique.

What is AngularJS?Front-end technologies are evolved very much in the last 20 years. From very basic HTML, CSS, and JavaScript to many libraries and frameworks are available now with great functionality. Developers are now able to build very complex user interfaces in a very short amount of time. Since 2010 JavaScript frameworks have started to evolve, and at first, AngularJS entered the market. It became very famous in a short time. Eventually, as complications increased, a new version of Angular was written but incompatible with the old version. Due to this popularity of Angular started to decrease.
Angular v2 and above is a complete rewrite and a TypeScript-based framework. Angular features mobile support, whereas AngularJS does not. Angular is an improvement and has compatibility with newer versions.
List of Angular AlternativesBelow are the different Angular Alternatives which are as follows:
1. ReactReact is becoming one of the most popular frameworks nowadays. Some developers are switching from Angular to React. One of the engineers at Facebook created it. React is used in the development of Single-page as well as mobile applications. React provided innovative features such as Virtual DOM and one-way data flow.
React is declarative and has components based. This allows composing complex UI’s while cleanly maintaining code. React works in the View layer of the application. React is smaller and usually requires additional libraries while developing complex React Applications.
2. VueAnother angular alternative is Vue. chúng tôi is a progressive JavaScript framework created by author Evan You, which is now open source. Vue is powerful enough to build single-page applications. Vue has some similar concepts from both AngularJS and React. It works in the View layer of an application, has a virtual DOM feature, and supports additional libraries, similar to React. Vue has a template style similar to Angular, but performance-wise, Vue is more powerful because it is more lightweight.
Vue offers features such as Reactive Interfaces, CSS transitions & Animation, custom filters, and straightforward code. Vue is easy to understand and flexible.
3. EmberEmber is an open-source JavaScript framework. It allows developers to build scalable single-page applications using best practices in a framework. Ember is based on Model-View-View-Model (MVVM) pattern.
Ember provides features such as Ember CLI, Ember templates, and the Ember Inspector tool used for debugging. Ember offers a friendly API that is easy to understand and work with.
4. MeteorMeteor is a complete platform for developing web and mobile apps in pure JavaScript. It’s a free and open-source JavaScript framework that runs on the client and server. Meteor integrates directly with MongoDB and can propagate data changes to the client without any extra code. Meteor uses its template engine for design and can be utilized with Angular, React, and Vue frameworks.
Meteor is the best Angular Alternative as it is a full-stack framework; it is possible to build everything in an application by learning it once. Meteor is easy to learn and enables it to build faster, making it a favorite for developers.
5. PolymerA polymer is an open-source JavaScript library for building web applications developed by Google developers. YouTube, Google Earth, Netflix, and Electronic Arts, among others, use Polymer.
A polymer is built on the concept of web components. Polymer offers features such as building custom HTML elements, cross-browser compatibility, and Polymer CLI. The polymer has some downsides, such as a lack of documentation and support, but being backed by Google, it has the potential to gain a significant market share.
6. BackboneDevelopers use Backbone, a lightweight JavaScript library designed for developing single-page applications. It is based on the Model-View-Presenter (MVP) design pattern, which abstracts data into models, and DOM into views and binds these two using events. chúng tôi has been in the market for a long time and has a mature platform.
Backbone provides features such as a RESTful JSON interface, Syncing with the back-end, and Event-Driven communication. Backbone allows the building of web applications and mobile applications in an organized and well-structured format.
7. AureliaAurelia is a next-gen modern open-source UI framework for developing web and mobile applications. It allows designing complex apps by using pure JavaScript or TypeScript. It follows the latest JavaScript standards. Aurelia is clean and has a nice API. Aurelia is concise and simple and at the same time, it is powerful and flexible. Aurelia is modular, it has a collection of libraries that can be used separately, and when combined, they form a powerful and robust framework.
8. MithrilThis is one of the most famous alternatives present for angular today. Mithril is a modern client-side JavaScript framework for building Single Page Applications. It’s small (< 8kb grip), fast, and provides routing and XHR utilities out of the box. Mithril is used by companies like Nike and Vimeo and open-source platforms like Liches.
It already has available documentation for common tasks. Mithril focuses on accomplishing meaningful work efficiently. Mithril is a complete platform for building web and mobile apps in pure JavaScript.

What 8 Of The Top Marketers Do On Social Media
There are so many opinions on what works and what doesn’t when it comes to social media.
I decided that it was time to take a look at my favorite marketers that I feel have successful social channels and see what it is they do to get ahead.
I boiled it down to eight marketers – all of whom are doing their own thing to create an engaged following and successful business.
1. Dr. Ai Addyson-Zhang Uses Platform-Specific ContentDr. Ai Addyson-Zhang is a digital education expert.
When you Google “Dr. Ai Addyson-Zhang” the top 6 results are as follows:
LinkedIn.
Twitter (with tweet cards).
Inside Higher Ed.
Her site (Classroomwithoutwalls.ai).
Facebook.
Medium.
It seems as though Dr. Ai has done a remarkable job of building authority on her social sites.
As I went through her profiles, I noticed something right off of the bat – all of the platforms have their own type of content.
Addyson-Zhang goes live on LinkedIn on Wednesdays and Fridays.
On Twitter, she jumps in Twitter chats, shares news around current events, and posts about her kids.
Facebook is a bit different; she shares photos of her children and square video recaps of her LinkedIn live shows.
Medium is really where Addyson-Zhang got her start. Just like everyone else, she uses Medium for long-form, blog-like content.
These blog posts incorporate media from all of her platforms such as screenshots of Tweets, embedded videos from LinkedIn and photos that she shares on Facebook.
Lesson LearnedBy differentiating the content you share on each platform, you are prepping the audience for the content you are going to be sharing.
2. Sarah Evans Does PRSarah Evans is a Digital Correspondent and the owner of Sevans Strategy.
Upon visiting her Twitter profile, you’ll learn right away that Sarah does PR and she does it well.
Her handle is @PRsarahevans – PR is right in her name!
And when you look at her bio, you’ll learn that she’s been featured in CNN, Mashable, and Forbes.
So yeah, she’s probably pretty good at what she does.
Not only does her name and bio clearly state that she does PR and is good at it, but all of her posts point to that as well.
If you follow Evans on LinkedIn or Twitter, you will see that she is always putting out calls for resources to cover certain stories.
To go a step further, she also shares out the tools and resources she uses on a daily basis.
Lesson LearnedThrough sharing your resources and letting others know what you do upfront, you could be in the perfect position to be seen as a thought leader.
3. Barry Schwartz Gets It DoneBarry Schwartz is probably best known for his work on Search Engine Roundtable, a personal-blog-style search engine optimization information hub.
He consistently puts out credible information concerning search.
He is the epitome of getting stuff done.
There are so many roadblocks people face when it comes to creating content that it is often easier to just walk away from creating altogether.
Schwartz doesn’t do that though.
Despite being an agency CEO, he still publishes blog posts every day Monday-Friday and publishes video blogs just about every other day.
Nothing is super fancy or super time-intensive, but it is always done and that is what is important.
Lesson LearnedIf you commit to getting things done and always showing up, you will build trust within your community.
4. Brian Fanzo Builds CommunityBrian Fanzo is a digital futurist and keynote speaker (disclosure: I work with him).
If you take a peek at his social platforms, you’ll likely see a mix of things ranging from photos of his daughters to thought leadership type videos.
His feeds are very human.
Fanzo shares the more intimate portions of his life.
He doesn’t just show the good, he’s also transparent about the bad.
When you join in on the conversations he takes part in, you’ll see that he goes out of his way to relate with others and keep the conversation going.
By being human, Fanzo builds a community rather than a following as his “followers” feel connected with him.
Lesson LearnedBe human on social media through transparency, authenticity, and conversation.
5. Dan Knowlton Is a StorytellerDan Knowlton is the co-founder of Knowlton, a Kent-based digital and social media marketing agency.
Truly, this comes as no surprise as you move through his social feeds.
All of the content Knowlton puts out is well made and tells a story.
From time to time, he posts clips from his latest podcast (in which he tells the story of being a business owner), tells stories of content he creates for his clients, and shares some fatherhood anecdotes.
No matter what piece of Dan’s content you stumble across, it’s almost a guarantee that it is a piece of a much larger story.
Lesson LearnedYour timelines should paint a picture of who you are.
Not all of them have to tell the same exact story, but you should always keep in mind the bigger picture before you post.
6. Julia McCoy Creates for OthersJulia McCoy is the CEO of Express Writers and a content marketer by trade, so it isn’t surprising that she publishes a lot of content.
I counted, on average:
2 posts daily on LinkedIn.
About 10 on Twitter daily.
Around 6 Facebook posts daily.
4 to 6 articles a month on Search Engine Journal.
Occasional posts to SEMrush, MarketingProfs, and Huffington Post.
And she’s written three books.
The woman is a content machine!
Here is the thing though:
She doesn’t only create content for herself.
As I mentioned earlier, McCoy is also a contributor to multiple publications (both in and outside of the marketing industry).
She uses her abilities to help others and does it often.
Instead of constantly selling her service, she helps others by creating for them.
Lesson LearnedThrough helping others, you broaden your network and position yourself as an expert – so help often!
7. Ross Simmonds Has ConversationsRoss Simmonds is a Digital Marketing Strategist at Foundation Marketing and he’s also the co-founder of Hustle & Grind.
When it comes to Simmonds’ social media activity, the majority of it is based around conversations.
Simmonds is 100% behind the idea of giving more than receiving (he straight up told me that!).
This must be why he is constantly looking to join in on conversations.
He answers tons of questions as well as most of his mentions.
By giving more information than he asks for, Simmonds is able to build a network without even trying!
Lesson LearnedLeave LinkedIn In-Mail in 2023 and focus on creating true connections through meaningful conversation.
8. Mari Smith Mastered CurationMari Smith, the Queen of Facebook, is known to most in the industry for her extensive knowledge of both organic and paid Facebook strategies.
As I was navigating through her social profiles, it was very apparent that Mari is always learning.
Mari Smith is a master content curator.
She shares regularly on all of her social platforms, but the majority of the time her feeds are a curation of the content she is learning from.
She doesn’t simply copy and paste links though, she goes out of her way to add her opinion and strategies as it relates to the article.
Lesson LearnedBy curating content, you ensure your feed is always fresh while also exercising your expertise.
What Works for You?It’s nearly impossible to think through all eight of these lessons every time you go to publish a piece of content, but it is important to remember the ones that work best for you.
Take into consideration the goals of your social channels, then select the lessons you feel are the most applicable to your and your social strategy.

Top 3 Upgrades Of The Qualcomm Snapdragon 8 Gen 2 Cpu
The American chip giant wants to set new standards with the Snapdragon 8 Gen 2. This chip comes with the code name “Kailua” and the model number is SM8550. Qualcomm aims to grab the Android flagship market with this chip. The new system-on-chip offers a total of eight CPU cores. It also comes with a prime core based on the ARM Cortex-X3 architecture. This chip achieves a clock rate of up to 3.2 gigahertz.
Let us now take a look at the top 3 upgrades that this chip brings
Qualcomm Snapdragon 8 Gen 2 upgrades1. Qualcomm now offers five instead of four high-performance CPU cores
There are two pairs of high-performance cores based on the Cortex-A710 and Cortex-A715 architectures. These cores clocks at a maximum of 2.8 gigahertz. It also comes with three energy-saving cores based on ARM Cortex-A510. These cores clocks a maximum of 2.0 gigahertz. Qualcomm is going head to head with its Taiwanese competitor MediaTek. Thus, it had to make changes to the cluster design of the CPU of its new chip. This is to secure the performance of this chip.
Through further optimizations, Qualcomm also wants to have increased things by up to 40 per cent. The chip’s new Adreno 740 GPU is said to deliver up to 25 per cent more performance. However, this chip also works 45 per cent more efficiently according to the company. The new GPU also supports real-time ray tracing. This is the first time for a Qualcomm chip to offer realistic lighting effects and reflections in games. The real-time ray tracing is one of the selling points of the new chip.
Gizchina News of the week2. High-end 5G modem & object recognition in the image processing processor
Another selling point of this chip is the new 5G modem. This chip integrates the Snapdragon X70 5G modem. This modem supports the use of two simultaneously active 5G SIMs. Thus, users can access two 5G networks at the same time if they need it. The modem also comes with the new Wi-Fi 7 standard as well as its own AI processor. This should ensure better reception and higher transmission rates.
The image processing processor of the Snapdragon 8 Gen 2 is referred to as the “Cognitive Image Signal Processor”. It should be able to use semantic segmentation to break down the motifs in photos and videos in order to then recognize certain objects in an image and then for an optimized display. Basically, the chip should be able to use optimal settings for faces, hair, sky and other things.
3. Better camera sensors
One aspect of the upgrade is the image preview. Users can see the final image or video even before the image processing software intervenes to optimize it. Qualcomm is also collaborating with Sony and Samsung. It wants to better match the image processing in the new Snapdragon SoC to the next generation of camera sensors from the two market leaders.
There is an interesting detail in terms of video recording and playback. Although the Snapdragon 8 Gen 2 can record videos with a maximum of 8K resolution, the chip can only operate internal and external displays with a maximum of 4K resolution. Other technical improvements include support for the even faster UFS 4.0 storage. It also supports the ability to spatially change the audio playback via headphones. It does this using the so-called spatial sound when the user turns their head.
It will probably only be a few days before the first devices based on the new Qualcomm Snapdragon 8 Gen 2 will arrive. Qualcomm itself only mentioned Motorola, Oppo and ASUS during the launch event. These companies are already planning the appropriate hardware. There is also Honor and other Chinese manufacturers battling to be the first to launch this chip.
TSMC ensures reliable availabilityIn addition to these upgrades, TSMC will also do its part in the process. The production of this new flagship processor uses TSMC’s 4nm manufacturing process. Having previously relied on Samsung as a manufacturing partner, Qualcomm falls back to TSMC’s 4nm node this time. Qualcomm is now completely switching back to TSMC. This is not only to ensure quality but also to ensure availability in sufficient quantities. Qualcomm has also done well in terms of AI performance and promises an increase by a factor of 4.35. Among other things, this should enable the new chip to carry out more complex tasks such as translation into several languages at the same time.
Learn The Essential Idea Of The Jsoup Maven
Introduction to jsoup maven
Basically, Java provides different types of libraries to the user, in which jsoup maven is one of the libraries that are provided by Java. Jsoup maven normally is used while we need to work with the real-time HTML pages. Jsoup maven provides the different types of API to fetch the different URLs and manipulates them with the help of HTML5 DOM and a selector of CSS as per requirement. When we talk about the working of jsoup maven, the jsoup maven implements the HTML5 specification and it parses the HTML web page the same as the DOM parser or we can say that is the same as modern browsers.

Web development, programming languages, Software testing & others
What is jsoup maven?Jsoup is an open-source Java library utilized essentially for separating information from HTML. It additionally permits you to control and yield HTML. It has a consistent improvement line, extraordinary documentation, and a familiar and adaptable API. Jsoup can likewise be utilized to parse and fabricate XML.
In this instructional exercise, we’ll utilize the Spring Blog to delineate a scratching exercise that exhibits a few components of jsoup:
Stacking: Bringing and parsing the HTML into a Document.
Separating: Choosing the ideal information into Elements and navigating it.
Removing: Getting properties, text, and HTML of hubs.
Changing: Adding/altering/eliminating hubs and altering their traits.
To utilize the jsoup library in your venture, add the reliance to your chúng tôi For the implementation of jsoup maven, we need the following dependencies.
Jsoup is working on real-time HTML web pages. It gives an extraordinarily favorable API to getting URLs and removing and controlling data, using the best of HTML5 DOM techniques and CSS selectors.
jsoup carries out the WHATWG HTML5 determination and parses HTML to similar DOM as present-day programs do.
Scratch and parse HTML from a URL, document, or string
Find and concentrate information, utilizing DOM crossing or CSS selectors
Control the HTML parts, qualities, and text.
Clean client submitted content against a safe list, to forestall XSS assaults
Yield clean HTML
Basically, jsoup is used to manage all assortments of web pages or we can say that HTML that we found so at that time jsoup creates a parse tree.
Install Jsoup with maven
Now let’s see how we can install Jsoup as follows.
There are two ways to install jsoup as follows.
By using maven dependence:
To introduce jsoup utilizing experts, add given reliance on chúng tôi record.
By Using Jar File:
Using jsoup
Before you can work with the DOM, you need the parable report markup. That is the message content that is shipped off the program. By then all worker side code will have executed and created whatever powerful substance is required. Jsoup addresses a Web page utilizing the org.jsoup.nodes.Document object. It tends to be made from a substance string or by means of an association. Commonly, the most straightforward decision is the last mentioned, however, there are situations where you might need to bring the page yourself, like where an intermediary worker is involved or qualifications are required.
By using two ways we can fetch the web pages, first, we need to establish the connection then call the get() function, and the second way we can use the jsoup function.
TreeBuilder class, however, has a state and is by all accounts accomplishing basically everything except it’s made from inside a technique in this way the entire activity is a string protected by the goodness of stack/string repression.
The jsoup safelist sanitizer works by parsing the info HTML (in a protected, sand-boxed climate), and afterward emphasizing through the parse tree and just permitting known-safe labels and characteristics (and qualities) through into the cleaned yield. It doesn’t utilize customary articulations, which are improper for this undertaking.
jsoup Examples
Now let’s see the example of jsoup maven as follows.
First, we need to create the maven project in eclipse as shown in the following screenshot as follows.
Now add above mentioned dependencies in the chúng tôi file as follows.
In the above code, we added jsoup dependencies as shown.
Now create a package inside the demo1 project and inside the package we need to create the class as shown in the following screenshot as follows.
Now inside the class file write the following code as follows.
package com.sample; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; import java.io.IOException; public class jclass { public static void main(String[] args) { Document docu; try { String title_page = docu.title(); System.out.println("title : " + title_page); Ele links_web = docu.select("a[href]"); for (Ele link : links_web) { System.out.println("n web_link : " + link.attr("href")); System.out.println("web_text : " + link.text()); } } catch (IOException e) { e.printStackTrace(); } } }Explanation
By using the above code, we try to find out the all hyperlinks of chúng tôi Here we first import the required packages and library as shown. After we write the code for HTTP protocol and how we can get the all hyperlinks for google as shown. The final output of the above program we illustrated by using the following screenshot as follows.
Similarly, we can write the program for fetching images, metadata and form input, etc.
ConclusionWe hope from this article you learn more about the jsoup maven. From the above article, we have taken in the essential idea of the jsoup maven and we also see the representation and example of jsoup maven. From this article, we learned how and when we use the jsoup maven.

Learn The Use Of Substring In Pyspark
Introduction to PySpark substring
PYSPARK SUBSTRING is a function that is used to extract the substring from a DataFrame in PySpark. By the term substring, we mean to refer to a part of a portion of a string. We can provide the position and the length of the string and can extract the relative substring from that.

Web development, programming languages, Software testing & others
PySpark SubString returns the substring of the column in PySpark.
We can also extract character from a String with the substring method in PySpark. All the required output from the substring is a subset of another String in a PySpark DataFrame. This function is used in PySpark to work deliberately with string type DataFrame and fetch the required needed pattern for the same.
Syntax
df.columnName.substr(s,l)column name is the name of the column in DataFrame where the operation needs to be done.
s: The starting Index of the PySpark Application.
l: The Length to which the Substring needs to be extracted.
df: The PySpark DataFrame.
b = a.withColumn("Sub_Name",a.Name.substr(1,3))Screenshot:
The withColumn function is used in PySpark to introduce New Columns in Spark DataFrame.
a. Name is the name of column name used to work with the DataFrame String whose value needs to be fetched.
Working Of Substring in PySparkLet us see somehow the SubString function works in PySpark:-
The substring function is a String Class Method. The return type of substring is of the Type String that is basically a substring of the DataFrame string we are working on.
A certain Index is specified starting with the start index and end index, the substring is basically the subtraction of End – Start Index.
String basically is a char[] having the character of the String with an offset and count. A new string is created with the same char[] while calling the substring method. A different offset and count is created that basically is dependent on the input variable provided by us for that particular string DataFrame.
The count is the length of the string in which we are working for a given DataFrame.
By This method, the value of the String is extracted using the index and input value in PySpark.
One more method prior to handling memory leakage is the creation of new char[] every time the method is called and no more offset and count fields in the string.
ExampleLet us see some Example of how the PYSPARK SubString function works:-
Example #1Let’s start by creating a small DataFrame on which we want our DataFrame substring method to work.
a= spark.createDataFrame(["SAM","JOHN","AND","ROBIN","ANAND"], "string").toDF("Name")This creates a Data Frame and the type of data in DataFrame is of type String.
Let us see the first example to check how substring normal function works:-
b=a.withColumn("Sub_Name",a.Name.substr(1,3)).show()This will create a New Column with the Name of Sub_Name with the SubStr
Screenshot:
Example #2Let’s check if we want to take the elements from the last index. The last index of a substring can be fetched by a (-) sign followed by the length of the String.
Let’s work with the same data frame as above and try to observe the scenario.
Creation of Data Frame.
a= spark.createDataFrame(["SAM","JOHN","AND","ROBIN","ANAND"], "string").toDF("Name")Let’s try to fetch a part of SubString from the last String Element.
b = a.withColumn("Name_End" ,a.Name.substr(-2,2))This prints out the last two elements from the Python Data Frame.
b = a.withColumn("Name_End" ,a.Name.substr(-3,3)).show()This will print the last 3 elements from the DataFrame.
Screenshot:
The substring can also be used to concatenate the two or more Substring from a Data Frame in PySpark and result in a new substring.
Let’s check an example for this by creating the same data Frame that was used in the previous example.
Creation of Data Frame.
a= spark.createDataFrame(["SAM","JOHN","AND","ROBIN","ANAND"], "string").toDF("Name")Now let’s try to concat two sub Strings and put that in a new column in a Python Data Frame.
Since SQL functions Concat or Lit is to be used for concatenation just we need to import a simple SQL function From PYSPARK.
from pyspark.sql.functions import concat, col, lit
This will all the necessary imports needed for concatenation.
b = a.withColumn("Concated_Value", concat(a.Name.substr(-3,3),lit("--"),a.Name.substr(1,3))).show()This will concatenate the last 3 values of a substring with the first 3 values and display the output in a new Column. If the string length is the same or smaller then all the strings will be returned as the output.
Screenshot:
From these above examples, we saw how the substring methods are used in PySpark for various Data Related operations.
ConclusionFrom the above article, we saw the use of SubString in PySpark. From various examples and classification, we tried to understand how the SubString method works in PySpark and what are is used at the programming level.
