The metaverse is getting a lot of hype at the moment, driven by companies like Facebook and its founder Mark Zuckerberg. The idea is appealing, but it’s not at all clear how you’re supposed to join the metaverse!

The problem is that all this talk of the metaverse makes it sound like a single place you access or subscribe to, but the truth is that there are a whole bunch of metaverses out there, and even more are coming.

The Metaverse in a Nutshell

This article assumes that you already more or less know what the metaverse is. If you don’t and you have some time on your hands, head over to our What Is the Metaverse explainer for an in-depth discussion. If you’re in a hurry, here’s the gist of it.

Metaverse Hardware Requirements Paying for (and Owning) Things in the Metaverse

One of the main features of a metaverse is that you can buy and own things within it. That includes virtual property, objects, and anything else that has utility within the metaverse. You’re also likely to have access to real-world products as well. Don’t be surprised if online retailers like Amazon eventually set up shop within a metaverse as well!

In general, there are two ways you can pay for something in a metaverse. The first is to simply use real-world currencies with a credit card, PayPal, or any of the other common digital payment platforms we already use. The second is to use cryptocurrency

Cryptocurrency and the Metaverse

Cryptocurrency and blockchain technology are especially interesting when it comes to the metaverse. That’s because the blockchain has a level of permanence that digital items bought from a central server can’t match. If it’s in the blockchain, then evidence that you own a specific digital asset only disappears when the last copy of the blockchain is destroyed.

NFTs (Non-fungible tokens) make much more sense in a metaverse context than they do in the real world because they can act as title deeds for your virtual property. Of course, if the content hosting and computing power for a given metaverse aren’t also decentralized, then NFTs don’t mean much.

There are already a few video games that make use of crypto and NFTs, such as Cryptokitties and Axie Infinity (AXS). AXS is a trading and battling game that also allows for the purchase of virtual property, and it lets users cash out their cryptocurrency every 14 days for use in the real world. This means it’s shaping up to be a kind of metaverse itself.

Going ahead, that’s likely to change. Especially since companies like Nike are getting ready to sell you virtual products! So perhaps it’s time to open a crypto wallet on the Bitcoin or Ethereum blockchain and load it with a little digital cash.

The Best Metaverse Platforms You Can Join Today

The metaverse isn’t one place, although one day all metaverses may be linked to each other using common standards and practices. For now, you’ll have to pick the one or two metaverse platforms that offer the sort of experience you want. Each digital world represented here has its own unique charms, and most are built to let third-party creators (including users) add their own content.

Horizon Worlds (Rift S & Quest 2)

Horizon Worlds can be accessed using a Quest 2 or Rift S (connected to a PC). It supports full motion tracking in 3D space and has an integrated game creation system. From a central plaza, users can enter portals to visit user-created worlds. The sky’s the limit with Horizon Worlds, and since it was only released to the public early in December of 2023, you can bet it’s still got plenty of new stuff coming.

On a technical level, Decentraland has some serious work ahead. It’s a little janky to be honest, but it’s also a fascinating collection of ideas. More than half a million people have already signed up to be part of this virtual world.

Having a crypto wallet is optional, but obviously, if you want to be a creator and have a place to keep your NFTs, you’ll need one. During the peak of the NFT craze, plots of land were selling for as much as $100,000!

Roblox (Windows, macOS, iOS, Android, Xbox One)

Roblox started out as an innovative game that coasted under the radar for quite some time. After exploding in popularity, it’s a smash-hit akin to Minecraft today and it also happens to be a metaverse.

Roblox is a free-to-play game, so it’s always been ready to host a vibrant economy. What really elevates it to metaverse status is Roblox Studio. Users can use Studio to create entire games, which players of Roblox can then play.

Individual digital items are also bought and sold on the platform, and every now and then Roblox hosts virtual events. So far, at least, Roblox is free of any sort of cryptocurrency, token, or blockchain technology, sticking with its own traditional non-crypto “Robux” currency.

The Sandbox Metaverse (iOS, Android, Windows and macOS)

The Sandbox is a blockchain-based game with its own token named SAND. Users can buy land, create their own content, create entire games, buy, sell, and explore everything within the Sandbox Metaverse.

At the time of writing The Sandbox Metaverse is in the Alpha stage, but there’s major hype around it with companies like Square Enix and Softbank investing millions of dollars in the company. While everything is still in an unfinished state on a technical level, the concepts are solid, and getting in early is probably a good idea!

VR Chat (Oculus VR, Oculus Quest, SteamVR, Windows Desktop Mode)

VRChat is a VR-centric virtual world that does have a desktop mode for use with flat screens but really demands VR hardware to get the most out of it.

In VRChat, users can create their own instanced worlds. That means it’s not an open persistent virtual world, but one that exists for the player and their friends.

VRChat has been popular for a large part of its existence, but the pandemic turbo-charged the number of users who were looking for a way to spend time with people, without physically being in their presence. As a new user, you don’t rate high enough on the trust system to start making your own content, but that’s only temporary. Stick around and stick to the rules, and you’ll get the keys to your own kingdom soon.

Second Life (Windows and macOS)

As the name suggests, Second Life is a place where people can live, hang out, experience things, buy property, customize their spaces, and much more. There are even official business premises in Second Life that you can visit for customer service or buy products.

As one of the oldest metaverses that’s still around, Second Life is due for some upgrades, and the people behind its creation are working on an evolution of this virtual world, although for now that still doesn’t include VR.

Fortnite (Windows, Switch, PlayStation 4, PlayStation 5, Xbox One, Xbox Series)

Fortnite started out as a video game and became one of the most popular free-to-play titles in history. Since then it’s grown into something more than a game, with people hanging out with each other rather than just shooting one another 24/7.

Fortnite has successfully dabbled in hosting non-game events such as concerts as well, becoming more like a social platform as time went by. Now Fortnite has launched Party Worlds, which is an expansion to the game that formally gives people a place to hang out, create their own party worlds, and generally qualifies the game as a full-fledged metaverse.

Fortnite is available on virtually every platform, but for the foreseeable future, iOS and macOS users are out of luck thanks to a massive legal battle with Apple.

Is This the Real Life?

Our digital screens have been a way to escape from the boredom or stresses of real life for decades. People already spend thousands of hours in-game worlds and on social platforms. They make friends there, they have fun there, and sometimes they have bad experiences.

How To Access The Metaverse On Oculus Quest 2?

Virtual Reality is quickly gaining momentum in 2023. Facebook changing its name to Meta is only one of the steps in that direction. The Metaverse is a concept that has amazed and confused users at the same time. Part of you who already have an Oculus Quest 2 must be thinking about how you can get access to the Metaverse. I’m here to tell you there are ways you can make that happen. So keep your Quest 2 by your side as I show you the ways you can get into the Metaverse with it.

How to Enter the Metaverse on Oculus Quest 2? (2023)

While this guide will discuss how to get into the Metaverse with the Oculus Quest 2, it will also discuss some other requirements. However, if you already know them then use the table below to skip to the process itself.

What Is the Metaverse?

Ways You Can Access the Metaverse

Strictly speaking, there is no one way to access the Metaverse. The concept doesn’t fully exist yet since it will require a single universal world that is interconnected like the Internet. So there is no single app named the Metaverse that can be opened. However, since the Metaverse is essentially a digital universe, bits and pieces of it exist on multiple platforms. These pieces are in the form of different apps and games that allow users to jump inside them and socialize and play while using avatars. So in order to get the Metaverse experience before it’s fully here with your Oculus Quest 2, you will need at least one of these apps installed on your Quest 2. I’ll be listing these apps down below so keep reading.

Things You Will Need to Access the Metaverse with Oculus Quest 2

Ready to jump into the Metaverse with your Oculus Quest 2? Hold your horses for just a bit more. There are a couple of things you will need before you can start experiencing it. Have a look at the list below and make sure to cross every item off your list.

1. An Oculus Quest 2

2. A Metaverse Application/Game

Metaverse Apps and Experiences You Can Get

Given below are some of the most popular apps you can use to get the Metaverse experience. However, do note that not all of them might be available depending on where you live. Go through the list below and choose the one that takes your fancy.

1. Horizon Worlds

2. Horizon Venues

Horizon Venues is a bit of a different take into the Metaverse. Designed to bring real-life events online, Venues lets Quest 2 users attend live events right from the comfort of their homes. Remember Fortnite’s Concert? Horizon Venues is an app dedicated just to events like that. However, instead of it being just a concert, Venues houses all kinds of events.

Source: Meta

From music events, recorded documentaries, to sports and live events, there’s a lot on offer. Horizon Venues also ties into the previous Worlds so your avatar will carry over to this app too creating the Metaverse experience. Those wanting to step into the Metaverse like this, should get Horizon Venues (Free) and get going right away. Like before, Venues might not be available depending on your region.

3. AltspaceVR 4. Rec Room

Rec Room is an experience that sits right in the middle of Altspace and Horizon Worlds. The game boasts beautiful graphics coupled with servers full of people. Like the apps above, you can don avatars and walk about having fun either alone or with other people. However, Rec Room brings something more to the table. Rec Room’s experience is a bit more game-oriented.

The experience houses a wide variety of games that Oculus Quest 2 users can play together. The games themselves are created by creators and are very interesting. So if you’re a Quest 2 user who wants to play in the Metaverse, Rec Room is one such experience you can get. Simply add Rec Room (Free) to your Oculus account and begin playing.

5. VRChat

Created long before the release of the Oculus Quest 2, VRChat is a game that has captured the digital hearts of thousands worldwide. VRChat allows users to create their own custom avatars and drop in and out of worlds. There are potentially hundreds of custom worlds available and range across various locations.

How to Dive into the Metaverse with the Oculus Quest 2?

Got NFTs, Metaverse, and web 3.0 on your marketing radar?

In a world where the digital and physical meet, metaverses offer an unprecedented opportunity to brands.

Lisa Buyer of The Buyer Group joined me on the SEJ Show to shed light on the Metaverse and what it is.

We talked about this new frontier that’s perfect for marketers who want their business in front of consumers. And it’s only getting started!

Meta is not the Metaverse. Meta is just one version of the Metaverse. We can’t say what the Metaverse will look like because we’re so early. –Lisa Buyer, 8:42

NFTs are very popular right now as art, which is excellent if you resonate with art, but the art also has to have some sort of utility, some sort of what it comes with. What are the uses and benefits I will get if I buy this NFT, or am I just buying a piece of art like I have a piece of art on my wall? –Lisa Buyer, 30:45

I see the whole web 3 movement as being decentralization. I don’t remember anything being this exciting since the internet launched in the first place. –Loren Baker, 12:00

[46:38] – Where’s a good place to learn about the Metaverse.

I see that brands are dedicating a portion of their marketing budget for the year to buying an NFT in a community that aligns with that brand’s mission and vision.

So it’s a way to embed yourself as a brand. You have to do it in the right way. It has to be authentic and transparent, and you have to be able to want to spend time in the community you’re aligning yourself with.

Forget having to launch an NFT collection. Just find an NFT collection or community that matches what your brand stands for and invest in it.–Lisa Buyer, 32:46

The most popular NFTs you see are those from people changing their avatars. Those are great from a marketing perspective because people buy into these NFT projects because of the community. –Lisa Buyer, 22:39

NFTs are just a way to really have your community invest in each other and believe in each other. So I think it’s the next generation of community building. –Lisa Buyer, 36:12

Meta Is Experiencing Serious Problems Due To The Metaverse

The multinational has dropped out of the “Top 20” of the biggest businesses in the world by market capitalization. And is close to doing the same in the ranking of US businesses.

The company’s net profit for the third quarter was $4,395 million. A decline of 52.2% from the outcome for the same period in 2023. Although the revenue decreased by 4.5%. Which could have been due to the overall environment, the expenses and costs increased by 19%.

The trend in revenues up to September is slightly better. And even shows an increase of 0.2% when we extend the picture to the total figure for the year. But the increase in the chapter on invoices is also more noticeable. The decline in revenue from Reality Labs, the division in charge of the metaverse that specializes in augmented and virtual reality. And the expectation that expenses will continue to rise are particularly noteworthy.

What do these numbers actually mean? in a very severe stock market decline. Since the announcement, the company’s shares have dropped more than 20%, which is a significant loss in value. This is the first time they have traded below $100 since 2023 when Meta was still Facebook. And they were facing some ups and downs.

Meta has just left the top 20 most-valued companies in the world

Do the rankings reflect that? Even though the rankings are just rankings, they provide context. Yes, there is a noticeable change in the case of Meta. It was removed from the list of the 20 largest companies in the world on Thursday, according to Bloomberg, which gave it a market value of 267.8 billion, placing it below Exxon, Johnson & Johnson, and major technology firms like Tesla, Amazon, Alphabet, Microsoft, and Apple. By market capitalization at the start of the year, Meta was the sixth largest company in the US.

The metaverse, too? Without knowing the answer to this basic question, it would be difficult to accept the most recent Meta results. Zuckerberg has made a firm decision to wager on the new virtual environment. And this translates into a significant, very significant load for the brands’s coffers. Despite having already spent more than 10,000 million dollars. It claims 15,000—the company’s results are still far from meeting the expectations they have raised.

Despite a sharp decline in expected revenue growth, “Meta continues to be overly aggressive with its investments in long-term plans”. According to Mandeep Singh, a Bloomberg Intelligence analyst. Given the lack of success to date with his efforts in the metaverse. We do not know the brand’s capital and operating expense view for 2023. The accounts show the plan’s annual costs of between 85,000 and 87,000 million.

Antitrust cases against the company

Mark Zuckerberg, the CEO of Meta, should testify by the Federal Trade Commission in its case against the business. In an effort to prevent Facebook from acquiring Within Unlimited. It’s the company behind the popular VR workout app Supernatural, the FTC sued the social media giant in July.

Also, according to Reuters, the agency listed 18 witnesses in a court document submitted on Friday to California’s Northern District Court, including Zuckerberg and Meta CTO Andrew Bosworth. According to court documents viewed by Reuters, the FTC intends to question Zuckerberg about Meta’s VR strategy. And how the company plans to support third party developers in addition to questions regarding the potential buy.

In addition, the FTC charged the business and Zuckerberg with trying to “unfair acquire” Within in July. John Newman, deputy director of the FTC’s Bureau of Competition, said at the time, “Instead of competing, Meta is trying to buy its way to the top”.

Pyspark Join On Multiple Columns

Introduction to PySpark Join on Multiple Columns

PySpark Join on multiple columns contains join operation, which combines the fields from two or more data frames. We are doing PySpark join of various conditions by applying the condition on different or same columns. We can eliminate the duplicate column from the data frame result using it. Join on multiple columns contains a lot of shuffling.

Web development, programming languages, Software testing & others

Overview

Using the join function, we can merge or join the column of two data frames into the PySpark. Different types of arguments in join will allow us to perform the different types of joins. We can use the outer join, inner join, left join, right join, left semi join, full join, anti join, and left anti join. In analytics, PySpark is a very important term; this open-source framework ensures that data is processed at high speed. It will be supported in different types of languages.

PySpark is a very important python library that analyzes data with exploration on a huge scale. It is used to design the ML pipeline for creating the ETL platform. Pyspark is used to join the multiple columns and will join the function the same as in SQL. The join function includes multiple columns depending on the situation.

How to use Join Multiple Columns in PySpark?

We must follow the steps below to use the PySpark Join multiple columns. First, we are installing the PySpark in our system.

In the below example, we are installing the PySpark in the windows system by using the pip command as follows.

pip install pyspark

Installing the module of PySpark in this step, we login into the shell of python as follows.

python

After logging into the python shell, we import the required packages we need to join the multiple columns.

import pyspark from chúng tôi import SparkSession

After importing the modules in this step, we create the first data frame.

Code:

spark_join = SparkSession.builder.appName ('sparkdf').getOrCreate() data_join = [(13, "ABC"), (15, "PQR"), (17, "XYZ")] columns_join = ['stud_id', 'stud_name'] dataframe_join = spark_join.createDataFrame (data_join, columns_join) dataframe_join.show()

Output:

After creating the first data frame now in this step we are creating the second data frame as follows.

Code:

spark_join1 = SparkSession.builder.appName ('sparkdf').getOrCreate() data_join1 = [(13, "ABC"), (15, "PQR"), (17, "XYZ")] columns_join1 = ['stud_id', 'stud_name'] dataframe_join1 = spark_join1.createDataFrame (data_join1, columns_join1) dataframe_join1.show ()

Output:

After creating the data frame, we are joining two columns from two different datasets.

Code:

import pyspark from chúng tôi import SparkSession spark_join = SparkSession.builder.appName ('sparkdf').getOrCreate() data_join = [(13, "ABC"), (15, "PQR"), (17, "XYZ")] columns_join = ['stud_id', 'NAME1'] dataframe_join = spark_join.createDataFrame (data_join, columns_join) data_join = [(13, "ABC"), (15, "PQR"), (17, "XYZ")] columns_join = ['stud_id', 'stud_name'] dataframe_join1 = spark_join.createDataFrame (data_join, columns_join) dataframe_join.join (dataframe_join1, (dataframe_join.stud_id == dataframe_join1.stud_id) & (dataframe_join.NAME1 == dataframe_join1.stud_name)).show()

Output:

How Multiple Columns work in PySpark?

Below are the different types of joins available in PySpark. As per join, we are working on the dataset.

Inner join

Left outer join

Right outer join

Full outer join

Cross join

Left semi join

Left anti-join.

The inner join is a general kind of join that was used to link various tables. It will be returning the records of one row, the below example shows how inner join will work as follows.

Code:

import pyspark from chúng tôi import SparkSession spark_join = SparkSession.builder.appName('sparkdf').getOrCreate() data_join = [( )] columns_join = ['stud_id', 'NAME1'] dataframe_join = spark_join.createDataFrame(data_join, columns_join) data_join = [( )] columns_join = ['stud_id', 'stud_name'] dataframe_join1 = spark_join.createDataFrame (data_join, columns_join) join = dataframe_join.join(dataframe_join1, on=['stud_id'], how='inner') join.show ()

Output:

The outer join into the PySpark will combine the result of the left and right outer join. The below example shows how outer join will work in PySpark as follows.

Code:

import pyspark from chúng tôi import SparkSession spark_join = SparkSession.builder.appName ('sparkdf').getOrCreate() data_join = [( )] columns_join = ['stud_id', 'NAME1'] dataframe_join = spark_join.createDataFrame(data_join, columns_join) data_join = [( )] columns_join = ['stud_id', 'stud_name'] dataframe_join1 = spark_join.createDataFrame (data_join, columns_join) join = dataframe_join.join(dataframe_join1, on=['stud_id'], how='outer') join.show()

Pyspark Join on Multiple Columns Dataframes

Pyspark join on multiple column data frames is used to join data frames. The below syntax shows how we can join multiple columns by using a data frame as follows:

Syntax:

join(right, joinExprs, joinType) join(right)

In the above first syntax right, joinExprs, joinType as an argument and we are using joinExprs to provide the condition of join. In a second syntax dataset of right is considered as the default join.

In the below example, we are creating the first dataset, which is the emp dataset, as follows.

Code:

Output:

In the below example, we are creating the second dataset for PySpark as follows. Here we are defining the emp set.

Code:

import pyspark from chúng tôi import SparkSession spark_join2 = SparkSession.builder.appName ('sparkdf').getOrCreate() data_join2 = [(31, "AC"), (33, "PR"), (35, "XZ")] columns_join2 = ['emp_id', 'emp_name'] dataframe_join2 = spark_join2.createDataFrame (data_join, columns_join) dataframe_join2.show()

Output:

Examples

Below are the different examples:

Example #1

Code:

import pyspark from chúng tôi import SparkSession spark_join1 = SparkSession.builder.appName('sparkdf').getOrCreate() data_join1 = [(21, "BC"), (23, "QR"), (25, "YZ")] columns_join1 = ['emp_id', 'emp_name'] dataframe_join1 = spark_join.createDataFrame(data_join, columns_join1) data_join1 = [(31, "AC"), (33, "PR"), (35, "XZ")] columns_join1 = ['emp_id', 'stud_name'] dataframe_join2 = spark_join.createDataFrame(data_join1, columns_join1) dataframe_join1.join(dataframe_join2, (dataframe_join1.emp_id == dataframe_join2.emp_id) & (dataframe_join1.emp_name == dataframe_join2.stud_name)).show()

Output:

Example #2

In the below example, we are using the inner left join.

Code:

import pyspark from chúng tôi import SparkSession spark_join1 = SparkSession.builder.appName ('sparkdf').getOrCreate() data_join1 = [(21, "BC"), (23, "QR"), (25, "YZ")] columns_join1 = ['emp_id', 'emp_name'] dataframe_join1 = spark_join.createDataFrame (data_join, columns_join1) data_join1 = [(31, "AC"), (33, "PR"), (35, "XZ")] columns_join1 = ['emp_id', 'stud_name'] dataframe_join2 = spark_join.createDataFrame (data_join, columns_join) join = dataframe_join1.join (dataframe_join2, on=['emp_name'], how='left') join.show()

Output:

Key Takeaways

In PySpark join on multiple columns, we can join multiple columns by using the function name as join also, we are using a conditional operator to join multiple columns.

We also join the PySpark multiple columns by using OR operator. We need to specify the condition while joining.

FAQ

Given below are the FAQs mentioned:

Q1. What is the use of multiple columns join in PySpark?

Answer: It is used to join the two or multiple columns. We join the column as per the condition that we have used.

Q2. Which operator is used to join the multiple columns in PySpark?

Answer: We can use the OR operator to join the multiple columns in PySpark. We are using a data frame for joining the multiple columns.

Q3. What are the join types used in PySpark?

Answer: We are using inner, left, right outer, left outer, cross join, anti, and semi-left join in PySpark.

Conclusion

There are different types of arguments in join that will allow us to perform different types of joins in PySpark. Pyspark joins on multiple columns contains join operation which was used to combine the fields from two or more frames of data.
