Real-Time Data Streaming Technologies – Complete Guide

Published

on

Real-time Data Streaming is data that is created continuously by thousands of data sources, which usually sends data to registers simultaneously, and in small sizes. Real-time data streaming contains a wide range of data such as log records created by customers using your mobile app or web applications, in-game player activity, e-commerce purchases, financial trading floors, information from social networks, or geospatial services, and telemetry from connected devices or instrumentation in data centers. Streaming technologies are at the forefront of the Hadoop ecosystem.

Data Ingestion

The first point to create when seeing streaming in the data lake is that though many of the offered streaming technologies are very flexible and can be used in many situations, a well-executed data lake offers strict instructions and progressions around ingestion.

Kafka

Kafka is the fresher of the data streaming technologies but is speedily gaining traction as a strong, accessible and fault-tolerant messaging method. Kafka is more of a transmission, making information “topics” presented to any subscribers who have the approval to listen in. Where Kafka does fall small is in marketable support.

Flume

Flume has generally been the one choice for flowing ingest and as such, is well-established in the Hadoop ecosystem and is sustained in all marketable Hadoop deliveries. Flume is a push-to-client scheme and works between two endpoints fairly than as a broadcast for any customer to plug into.

Data Processing

Once you have a stream of data controlled for your information lake, there are some options for receiving that data into a storable, useable form. With Flume, it’s possible to compose straight to HDFS with in-built sinks. Kafka does not have any in-built connectors.

Storm

storm is a factual real-time handling structure, taking in a stream as a whole “event,” slightly than a sequence of small collections. This means that Storm has very small latency and is well-matched to information that must be consumed as a sole entity.

Spark

Spark is broadly known for its in-memory treating abilities and the Spark Streaming technologies works on much of a similar basis. Spark is not a truthfully a “real-time” method. Instead, it procedures in micro-batches at distinct breaks.

Flink

Flink is a bit of a hybrid between Spark and Storm. While Spark is a batch structure with no true flowing support and Storm is a flowing structure with no batch provision, Flink contains frameworks for both streaming and group processing.

Samza

Apache Samza is another spread stream processing structure that is strongly knotted to the Apache Kafka messaging system. Samza is created especially to take benefit from Kafka’s unique style and assurances fault acceptance, buffering and state stores.

Conclusion

We have plenty of choices for processing within a big data system. For stream-only workloads, Storm has wide language provision and so can bring very short latency processing. Kafka and Kinesis are gathering up fast and given that their set of benefits. For batch-only workloads that are not time-sensitive, Hadoop MapReduce is the best choice.

Cryptocurrency has entered the mainstream and if you feel like you’re way behind, you’re not alone.

TAMPA, Fla. — At Florida’s Bitcoin and Blockchain Summit earlier this month (which was held here in Tampa) Mayor Jane Castor announced she was going to take her next paycheck in bitcoin.

Miami and New York’s mayors recently did the same.

Over in Los Angeles, the Staples Center, one of the world’s most famous arenas, will get its name changed to “Crypto.com Arena” come Christmas Day, for a reported $700 million.

Apologies for coming late to the conversation – we’ve been busy preparing for today’s cryptocurrency conference here in the @CityofTampa. 🪙😏 But I’m certainly up for the challenge! #ForbesTopEmergingTechnologyCity #FloridasTechCapitol #TechTown

Cryptocurrency has entered the mainstream and if you feel like you’re way behind, you’re not alone. But, all of this Bitcoin and crypto talk can be a heck of a lot for us newbies to the coin game, even if it has been around for more than a decade.

So, let’s learn together. It’s a journey I like to call: Crypto 101.

To make this easier, we’ll break it down into four parts:

  • What is cryptocurrency?
  • How can I buy it?
  • How safe is it? 
  • Am I too late to the game to get in?

What is cryptocurrency?

Bitcoin, Blockchain, Coinbase, Etherium, To the Moon – it’s all a part of the crypto vernacular, but let’s get down to the basics.

In simplistic terms, it’s essentially a peer-to-peer digital cash system that’s decentralized, so it doesn’t go through any bank, government or third party, like how we’d traditionally use cash or a credit card.

“Cryptocurrency, very simply, is just a digital or virtual currency that’s secured by code, which makes it nearly impossible to counterfeit,” said Nick Agar, the founder of AXIA, an ecosystem and non-profit for hyper deflationary virtual currency. 

“These currencies run on something called a blockchain, which is a distributed ledger where these transactions are being tracked. What makes them that much more secure is they have to go through a proper validation process.”

And that process is called mining, which verifies the transaction via sophisticated computers solving very complex math problems.

“In bitcoin, all of these miners are processing the transaction, which is ultimately securing the network and making sure all the transactions are secure,” said Mark Palomba, the founder and chief investment officer at Deltacore Capital, a hedge fund for digital assets based here in Tampa. 

“In return, they get newly minted bitcoin.”

Najah Roberts, the chief visionary officer of a crypto services company called Crypto Blockchain Plug, likened it to what we’re already doing with digital payments, like Apple Pay or Venmo.

“Money is changing,” Roberts said. “We’re already in the digital space…this is just one step further, which is a digital currency, such as bitcoin. I tell people to get knowledgeable about Bitcoin first.” 

So let’s do that because there are thousands of cryptocurrencies, but Bitcoin is the most popular and the most lucrative. It’s like the McDonald’s of crypto. 

Satoshi Nakamoto created bitcoin in 2009. He wanted an independent way for users to send money to each other – fast and with little to no transaction fee.

“There will only be 21 million bitcoins ever in existence,” Palomba said. “They are slowly trickled into the flow of the system by miners, decreasing every four years until 2141.”

So, they’re limited and clearly in demand, with Bitcoin exploding over the last decade. CaseBitcoin says its 10-year compounded growth rate is unmatched in financial history, nearly tripling your money every year for a decade.

How can I buy it?

Okay, so now I’ve got your interest, but how do you buy, trade or sell crypto, like Bitcoin?

“Always make sure you’re using a trusted exchange with a lot of security,” Palomba said. “In the U.S., the biggest exchange is Coinbase, which is the quickest and easiest way for beginners to get into the market.”

“Similar to when you open a bank account,” Agar said. “You go through a registration process at one of these exchanges and then you receive one of these cryptocurrency wallets to go into the market and purchase whatever crypto you want at that time.”

How safe is it?

So, now that you know how to buy some, how safe is it?

The Federal Trade Commission says consumers lost north of $80 million on crypto scams during the back end of 2020 and the first quarter of 2021, but experts say that has more to do with a lack of research and knowledge than it does with the crypto process itself.

Blockchain technology is known for its unparalleled security. The user has their identity protected, but all transactions are public, making it nearly impossible to hack or cheat the system. With thousands of miners keeping track of the transactions and showing proof of their work to get paid, it increases the security.

“We should actually be looking to crypto as a far, far more secure way to make our payments,” Agar said. “Because of the immutable nature of blockchain transactions and because they’re so transparent on that ledger at all times.”

“Anybody that’s talking about massive gains, immediately you have to put up your red flags,” Roberts said. “I meet so many people who are scammed in this space and they don’t know better. The moment you begin to get greedy, that’s the time you begin to get scammed.”

Is it too late to get in?

We’re a decade in, so is it too late to get into the crypto game, or are we just getting started?

“This is a marketplace that’s in its infancy,” Agar said. “We’re almost at an inflection point in our economic system in terms of what is possible.”

“The sky is the limit,” Palomba said. “We’re only scratching the surface on the technology and the tools and the solutions that this can really offer. In 5-10 years, I don’t think we’ll recognize a lot of the difference that it’ll make in how we transact and do things on the internet.”

Google: Machine Written Content May Be Okay For Ranking Soon One Day

Published

on

Picture of Google text with Mac computer

Google has talked about how machine written content is currently against Google’s guidelines but some day might not be. We heard Google talk about this change in 2017, yes over four years ago, but still today, machine generated content is against Google’s guidelines. But that may change soon, suggests John Mueller of Google.

John Mueller spoke about this topic again, just this past Friday, about how Google will eventually not care if the content is generated by a machine or a human but rather if the content is overall quality. This came up at the 54:19 mark where John said “my feeling is at some point that is going to shift a little bit in the sense that we’ll focus more on the quality rather than how it was generated.”

John feels that some time in the near future that “some mix of maybe automatically generated content and human curated content I imagine will become normal.”

You can listen to it here at the 54 mark:

Here is the transcript:

From our guidelines it is the case that if it’s automatically generated content it should be blocked by robots for example. But my feeling is at some point that is going to shift a little bit in the sense that we’ll focus more on the quality rather than how it was generated.

And that’s something where I could imagine that there might be some setups for automatically generated content where you can actually create something that is fairly useful, where based on maybe the input data that comes in it’s actually something that is useful for people. So I know for example I think in the US some of the news sites use feeds from the different institutes for earthquake detection and they will automatically generate a news article if they see that one of these feeds says oh there was an earthquake in this big city. And they will take this automatically generated content and publish it initially because it’s like as soon as possible get the information out there. But they’ll also have people who go in and actually create something useful on top of that.

So some mix of maybe automatically generated content and human curated content I imagine will become normal. But we’ll continue to have the the really low effort automatically generated content as well where people just say oh I want to target this keywords give me five paragraphs of text and make it look like it’s written in English. And you like a normal person looks at it and reads through it and says this doesn’t make much sense or these sentences don’t fit together. And this kind of low effort content I think will continue to be something that our systems will try to recognize as low quality maybe spam and treat appropriately. And in the end if it’s low quality content it doesn’t matter if it was written by a person or by a machine, it’s like it’s not that useful for people.

Latest Article Crypto market hits $2.8tn as US House passes $1.2tn infrastructure bill

Published

latest-article-crypto-market-hits-$28tn-as-us-house-passes-$1.2tn-infrastructure-bill-–-coin-rivet

The value of the overall crypto market surpassed $2.8 trillion, according to CoinGecko.com.

It follows a move by the US House of Representatives to pass the $1.2tn Infrastructure Bill which is almost the same value as the entire market cap of Bitcoin.

The bill was signed into law by President Joe Biden, and was designed to enforce new provisions in relation to crypto-tax reporting for all US citizens.

The bill says some obligations for the crypto community must be fulfilled, including all digital asset transactions worth more than $10,000 to be reported to the IRS.

The overall crypto market cap of $2tn was crossed seven months ago while the $1tn cap was surpassed three months before that. It took 13 years – from the publication of the Bitcoin whitepaper at the end of 2008 – until this January for the market to hit the first trillion.

Records reached by Ethereum and Solana helped push the combined market cap of all cryptos above $2.75 trillion for the first time in its history, while Bitcoin alone is now worth more than US behemoths such as Facebook and Tesla with a market cap above $1.19tn.

Crypto market popular with traditional finance institutions

Compared to these numbers, the world’s largest bank – JPMorgan Chase – has a market cap of $503bn that represents $40bn less than that of Ethereum’s.

Together with the rest of the top 12 world’s biggest banks, it gives an overall market cap of just below $2.7tn for the traditional finance leaders who were strongly resisting new digital money.

However, some of the biggest players in the US and Europe started offering crypto trading services to institutional clients.

One of them is Singapore’s DBS Group, which became one of the first to offer the service to wealthy clients. The country’s Monetary Authority (MAS) also said recently there could be “a role” for stablecoins in future finance “that extends beyond pure speculation and illicit finance”.

Australia’s Commonwealth Bank also confirmed its intention to offer a platform for retail customers to trade cryptocurrencies on its mobile banking app.
