There are multiple ways to ingest data streams into the Apache Kafka topic and subsequently deliver to various types of consumers who are hooked to the topic. The stream of data that collects continuously from the topic by consumers, passes through multiple data pipelines and then stream processing engines like Apache Spark, Apache Flink, Amazon Kinesis, etc and eventually landed upon the real-time applications to deliver a final data-driven decision. From finances, manufacturing, insurance, telecom, healthcare, commerce, and more, real-time applications are becoming the best solution for organizations to take immediate action, gain insights from the updated data. In the present day, Apache Kafka shapes the central nervous system that brings data from all aspects of the business to the large information operational hubs where choices are made.

The text files contain unformatted ASCII text and are commonly used for the storage of information. Each line of the file represents a data record and can be updated continuously to store. Every insert of a new line or lines on the text file can be considered as new data insertion on the file. Henceforth, every addition of a new line or lines on the text file continuously either by humans or applications (no modification on the already inserted line)and subsequently moves or sends to a different location can be considered as data streaming from the file. Every addition of a new line or row in the text file can be analyzed continuously by exporting the new line/lines to the Kafka topic and importing them by consumers that hooks up with the topic.

Overview

EclipseLink has two types of caches: the shared cache (L2) maintains objects read from database; and the isolated cache (L1) holds objects for various operations during the lifecycle of a transaction. L2 lifecycle is tied to a particular JVM and spans multiple transactions. Cache coordination between different JVMs is off by default. EclipseLink provides a distributed cache coordination feature that you can enable to ensure data in distributed applications remains current. Both L1 and L2 cache store domain objects.

“Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.” — redis.io

Machine learning-based applications have seen significant commercial success in several mainstream consumer applications in the recent past. Self-driving cars, stock-trading bots, robo-advisors, Amazon’s Alexa, and Apple’s Deep Fusion and Siri are some of the renowned examples of commercial success with artificial intelligence and machine learning. AI has also made our lives easier by improving the customer experience of the products we use. Google’s text generation software, Netflix’s recommendation engine, and Facebook and Twitter’s fake news detection are other prime examples. In fact, every single technology company uses AI in its mainstream applications either directly or indirectly. Non-technology companies are also using AI to improve customer experience, improve efficiency, and generate new revenue streams. Chatbots, robo-advisors, systems that predict system failures, and products that generate efficient supply chain routes are some of the prominent ways in which non-technology companies use AI. This is leads to a popular belief that AI and ML are primarily used by technology companies or they are being used by non-tech companies to build AI-based products.

This popular perception is not true. There are plenty of avenues in which AI/ ML is being used or can be used by non-tech and non-product-based groups to generate insights. In this article, I am going to share with you four ways in which you can augment advanced analytics into your analytics strategy to generate insights.

As a web designer, you’re constantly being bombarded with messages that tell you to acquire new skills, try new tools, and keep on hustling.

But if you’re constantly changing things up, does it do the opposite of what you originally set out to do? In other words, if you always have to start over, is it possible to ever really achieve anything?

I think it ultimately depends on why you’re making the change.

When Change Is the Right Move for Web Designers

One of the reasons I despise New Year’s resolutions is because it’s change for the sake of change:

It’s a new year, so it’s time to get all hyped up about this one thing I need to change about myself!

There’s a reason why so many resolutions fail by February. When you force a change, it’s really hard to stay invested in it, especially if it’s something you’ve chosen to do because everyone else has.

Change should be driven by necessity.

That said, when it comes time to make changes as a web designer, is it ever really necessary? Or are you learning new skills, trying new tools, or switching up your client list simply because it’s what you believe you have to do?

It’s important to be open to change, but you should only invest your time, money, or effort when it’s the absolute right move for you. Here are some ways you’ll know when that’s the case:

Learn New Skills To…

…Round Out the Basics

If you’re a new designer and there are gaps in your education and training (and I don’t mean formally, just in general), then there’s no reason to hesitate in spending time to acquire those skills.

This doesn’t just go for basic skills as a web designer or as a coder. This also goes for skills you need to become a successful freelancer.

…Add Evergreen Skills to Future-Proof Your Position

As you move up in your career, you’ll eventually find other skills worth learning. Just make sure they’ll help you move the needle.

The best way to do that is to focus on acquiring evergreen skills that’ll always be useful to you, no matter what stage you’re at in your career or how the design landscape changes. They should also go beyond the average skill set of a designer, so they help you stand out further from the pack.

… Create a Better Situation for Yourself

The web is constantly evolving, which means that your responsibilities and skills as a web designer will have to change in order to adapt. Whenever one of these shake-ups occurs, you should either be ready to master the needed skill right away or, better yet, have been working on it beforehand.

Take, Google’s mobile-first indexing, for instance. It announced it was going to be making this shift years before website rankings were impacted. Designers had plenty of time to not only learn what was needed to design for the mobile-first web, but to get all their existing clients’ sites in shape for it.

Adopt New Tools When…

…Your Existing Ones Are Slowing You Down

If you’re doing a lot of things from-scratch (like writing emails to clients or creating contracts), that’s a good sign your toolbox needs some improvement.

As a web designer, you should be focused on creating, not on the tedious details involved in running a business or communicating with clients. That’s just not a good use of your time. A lot of this stuff can easily be automated with tools and templates.

…You’re Turning Down Business

In some cases, it’s the right thing to say “no” to prospective clients — like when they’re a bad fit or can’t afford your rates. However, there are other times when you desperately want to be able to say “yes”, but you don’t have the capacity for the job or you’re unable to cover the full scope of what they need.

This is where new tools come in handy. For instance, let’s say you’ve been approached by a ecommerce company that not only wants you to build a new store, but also needs it fully optimized for search (it’s not the first time this has happened either). Rather than turn something like that down, you may find that the addition of an SEO tool to your toolbox is all you need to be able to say “yes”.

…You Have Extra Room in Your Budget

Obviously, you don’t want to throw away money on a bunch of tools simply because a ton of people are talking about them. But you’ll eventually get to a point where the tools that served you well in the first year of business need to be replaced.

If you get to a point where you have extra time to experiment and there’s room in your budget for upgraded tools, go ahead and assess what you currently have and test out replacement solutions that will help you work better, faster, and smarter.

Look for New Business Opportunities If…

…You’re Not Doing Well

“Well” here is subjective. For instance:

  • If you’re not doing well financially, you probably need to look for more clients;
  • If you’re not doing well in terms of how you get along with clients, you should explore a niche that’s a better fit;
  • If you’re not happy with your job because burnout and stress have overtaken your life, then you might consider exploring other avenues of work.

When something has been amiss for awhile, the last thing you should do is lean into it and hope it gets better.

…The Web is Changing

Notice a trend here? Each of these changes (skills, tools, and now business opportunities) is often driven by the fact that the web is always changing. And as the web changes, you have to be ready to evolve.

In terms of business opportunities, what you’ll realistically need to do is look for new kinds of design work as technologies make your job obsolete. Take website builders like Wix or Shopify, for example. As business owners and entrepreneurs take it upon themselves to build their own websites, more and more web designers will need to find other kinds of clients and jobs to take on.

…You Want to Diversify Your Income

This is something many web designers are doing already as they’ve discovered how beneficial it is to have predictable recurring revenue streams.

But even if you’ve already found one way to diversify and stabilize your income (like by offering website maintenance services), you may become interested in exploring other opportunities along the way. If you have the capacity to pursue them, then go for it.

Is Change a Good Idea?

As you can see, change can be a very good thing for a web designer, their business, and their clients. However, there should be a very good reason for the change and you need to prepare yourself for how it’s going to impact what you’re doing now before implementing it. No amount of change can happen without some level of sacrifice.

Check out the article below to become a master of Java Streams!

Declarative code (e.g. functional composition with Streams) provides superior code metrics in many cases. Code your way through this hands-on-lab article series and mature into a better Java programmer by becoming a Master of Java Streams.

The whole idea with Streams is to represent a pipeline through which data will flow and the pipeline’s functions operate on the data. This way, functional-style operations on Streams of elements can be expressed. This article is the first out of five where you will learn firsthand how to become a Master of Streams. We start with basic stream examples and progress with more complex tasks until you know how to connect standard Java Streams to databases in the Cloud.

Java 8
No matter what version of the JDK we are on, Java 8 is not going anywhere.

Java 8 introduced a new era of Java. Everything from lambda expressions and functional programming to Streams and collections — DZone was there to document it all.

So whether you’re migrating over to Java 9 or Java 11, or maybe even Java 13, Java 8 concepts and features are still very much alive in the JDK. And understanding these core concepts can help tremendously when it’s time to move beyond Java 8.
