In today's world of real-time data processing and analytics, streaming databases have become an essential tool for businesses that want to stay ahead of the game. These databases are specifically designed to handle data that is generated continuously and at high volumes, making them perfect for use cases such as the Internet of Things (IoT), financial trading, and social media analytics. However, with so many options available in the market, choosing the right streaming database can be a daunting task.
This post helps you understand what SQL streaming is, the streaming database, when and why to use it, and discusses some key factors that you should consider when choosing the right streaming database for your business.
It says that match is now a reserved keyword. DaniWeb's matching algorithm has many instances of the variable $match, the function match() and even a class named Match. What do I need to do in order to upgrade?
In this age where new technologies are coming up rapidly, it’s very important to keep up with speed and ensure the highest application quality is delivered to the customers. If we see the user base of different operating systems, we can see that Android is currently the market leader worldwide. Let’s see this market trend:
Many companies want a mobile version of their web applications or even directly create mobile applications for their customers. Therefore, it must be tested thoroughly to ensure customers get quality applications.
The benefits of adopting cloud-native practices have been talked about by industry professionals ad nauseam, with everyone extolling its ability to lower costs, easily scale, and fuel innovation like never before.
In the current fast-paced environment, both AR and VR are becoming more and more useful. Both technologies have a lot in common with each other, but they are also very different. So, in this article, we'll explain the difference between augmented reality and virtual reality.
What Is AR vs. VR?
AR is a digitally enhanced version of reality in which users can communicate with graphical interfaces that look like a mobile phone or an app. Augmented reality is the technology that connects digital data like text, images, and 3D Models in a real-world atmosphere.
In this article, you will learn how to build a GraalVM image for your Spring Boot application. Following these practical steps, you will be able to apply them to your own Spring Boot application. Enjoy!
Introduction
Java is a great programming language and is platform independent. Write once, run anywhere! But this comes at a cost. Java is portable because Java compiles your code to bytecode. Bytecode is computer object code, which an interpreter, (read: Virtual Machine), can interpret and convert to machine code. When you start your Java application, the Virtual Machine will convert the bytecode into bytecode specific for the platform, called native machine code. This is done by the just-in-time compiler (JIT). As you will understand, this conversion takes some time during startup.
Spring Boot 3 is riding the wave in the Java world: a few months have passed since the release, and the community has already started migrating to the new version. The usage of parent pom 3.0.2 is approaching 500 on Maven Central!
An exciting new feature of Spring Boot is the baked-in support from GraalVM Native Image. We have been waiting for this moment for years. The time to migrate our projects to Native Image is now!
I first ran into the concept of Continuous Integration (CI) when the Mozilla project launched. It included a rudimentary build server as part of the process and this was revolutionary at the time. I was maintaining a C++ project that took two hours to build and link. We rarely went through a clean build, which created compounding problems as bad code was committed into the project.
A lot has changed since those old days. CI products are all over the place and, as Java developers, we enjoy a richness of capabilities like never before. But I’m getting ahead of myself. Let’s start with the basics.
Elasticsearch is a distributed, full-text search and analytics engine that allows you to store, search, and analyze large volumes of data quickly and in near real-time. In this Elasticsearch tutorial, you’ll get to know what is Elasticsearch, how Elasticsearch works, and how you can configure, install, and run it. Also, you’ll understand its benefits and what is Elasticseach used for. So, let’s begin.
What Is ElasticSearch?
Elasticsearch is an open-source search and analytics engine that allows you to store, search, and analyze large amounts of data in real-time. It is based on the Lucene search engine library and is designed to provide distributed and scalable search capabilities, making it ideal for use in a variety of applications such as e-commerce, log analysis, and business intelligence.
ChatGPT has taken the world by storm, and this week, OpenAI released the ChatGPT API. I’ve spent some time playing with ChatGPT in the browser, but the best way to really get on board with these new capabilities is to try building something with it. With the API available, now is that time.
As per StackOverflow insights, JavaScript is the most popular programming language. As the power of web and mobile is increasing day by day, JavaScript and JavaScript frameworks are becoming more popular. It would not be surprising to hear that JavaScript has become a preference for test automation as well. Over the past few years, a lot of development has happened in the open-source JavaScript based test automation framework development and now we have multiple JavaScript testing frameworks that are robust enough to be used professionally. There are scalable frameworks that can be used by web developers and testers to automate even unit test cases and create complete end-to-end automation test suites. Mocha is one JavaScript testing framework that has been well renowned since 2016, as per StateofJS.
With that said, when we talk about JavaScript automation testing, we can’t afford not to loop Selenium into the discussion. So I thought coming up with a step-by-step Mocha testing tutorial on the framework will be beneficial for you to kickstart your JavaScript automation testing with Mocha and Selenium. We will also be looking into how you can run it on the LambdaTest automation testing platform to get a better browser coverage and faster execution times. By the end of this Mocha testing tutorial, you will have a clear understanding of the setup, installation, and execution of your first automation script with Mocha for JavaScript testing.
We have quite a history with real-time technologies here at CodePen. We’ve had all sorts of things in production from hand-rolled and self-hosted ideas, to services that don’t even exist anymore, to well-known products like Google Firebase’s Realtime Database. Sometimes our real-time needs are fairly complex, like our Collab Mode PRO feature that allows people to code within the same code editors at the same time, which is capable of conflict resolution and that kind of exotic science. Sometimes our real-time needs are more basic. Our real-time Live View is closer to the basic side. It has just a few jobs:
As a PRO user is editing a Pen they own, when the preview updates, update Live View as well.
If the Pen update is only CSS, inject the new CSS without refreshing the preview entirely.
That this is mostly single-directional real-time-ness. The only thing Live View needs to do is authenticate to ensure the user is PRO (and looking at a Pen they own), but there are otherwise no events it needs to send back.
We have been keeping our eye on Cloudflare’s Durable Objects technology to use for future real-time needs of CodePen. We’re already heavy users of Cloudflare Workers, K/V storage, and HTMLRewriter — and Durable Objects fit into that same ballpark. The fairly basic nature of Live View made it a perfect testing ground to try out Durable Objects. Nothing like getting a new technology to production to really kick the tires! It’s not that Durable Objects isn’t capable of complex situations (in fact, it’s quite good at it), we just wanted to keep complexity low for our first rodeo.
The one-nickel version of how Live View Works:
If a Pen is owned by a PRO user, it’ll kick off a connection to a Cloudflare Worker which establishes a connection to a Durable Object. Then if Live View is opened, that web page does the same thing, ultimately connecting to the same Durable Object. Now messages can be passed from the Pen Editor to Live View (“Hey! A new preview is ready!”).
Live View was using Firebase Realtime Database before and now we’ve converted it to using Durable Objects. Here’s why we started down this road:
We’re vetting the Durable Objects for more complex and higher-scale real-time needs. If this goes well, we know we’ve found a good path for future projects.
We already use Cloudflare products for a variety of things and like the fit. If we can keep investing in that, we’re taking advantage of existing knowledge and consolidating expertise. We’ll need to keep an eye on the price of course!
In particular, we use Cloudflare Workers a bunch. A Cloudflare Worker is needed to talk to a Durable Object, so we already have a bit of infrastructure for that (testing, deployment, local dev, etc.).
Firebase Realtime Database does a decent job of shooting data between connected clients, but it’s arguably not a “real” messaging service. You can’t run code using just it, for example, so all the logic and whatnot is done by clients receiving the data. Using this new setup, we have the opportunity to run code at the Worker level (in our case, auth) and the Durable Object level (in our case, send messages to Live View(s)).
We would like need it to be fast.
What did we find? Drumroll, I suppose…
So far so good! Over the course of a few days, we slowly rolled it out to 100% of PRO users and experienced no issues.
The tech slotted nicely into things we were already doing, so that’s a win. It feels so far like we’ve found a good solution for all future real-time needs.
The removal of Firebase from Live View means a fairly dramatic reduction in client-side code. No library is needed at all. The Live View-specific code is now a hand-rolled bit of JavaScript that uses Web Workers natively to connect/re-connect to the Cloudflare Worker. It’s 1.5 KB gzipped. That’s a form of speed improvement for users right there.
Pitted against Live View using Firebase Realtime Database, not only is the page load faster, the messages are faster too. Live View now (almost weirdly) refreshes faster than the on-page editor does. We’ve found about an 80-250 millisecond message ping speed, with 80 being coast-to-coast in the U.S. and 250 being U.S. to Australia.
This is not really a question, since I can make it work. It's just something I have not seen before and I think it is odd. I'm writing some unit tests. One test works fine, but when I change a parameter for another test, it gives an error. The parameters do match what is passed into the methods. I just didn't retype the test method attribute each time here. This is not my actual code because that is the property of my employer and I am not allowed to post any of it. Hopefully there are no typos due to typing it out instead of copy/paste. This is C#.
Have any of you seen this before, and do you know why it would do this?
[TestMethod]
[DataRow(enumName.SomeValue, "stringValue", new string[] {"aryVal1","aryVal2"})] //this works, but when I remove the string value, it does not
[DataRow(enumName.SomeValue, new string[] {"aryVal1","aryVal2"})] //this gives error CS0182: An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type
[DataRow( new string[] {"aryVal1","aryVal2"}, enumName.SomeValue)] //this works, but all I did was change the order of the parameters
After being voted as the best programming language in the year 2018, Python still continues rising up the charts and currently ranks as the third best programming language just after Java and C, as per the index published by Tiobe. With the increasing use of this language, the popularity of test automation frameworks based on Python is increasing as well. Obviously, developers and testers will get a little bit confused when it comes to choosing the best framework for their project. While choosing one, you should judge a lot of things, the script quality of the framework, test case simplicity and the technique to run the modules and find out their weaknesses. This is my attempt to help you compare the top five Python frameworks for test automation in 2019, and their advantages and disadvantages over the other frameworks. So you could choose the ideal Python framework for test automation according to your needs.
Robot Framework
Used mostly for development that is acceptance test-driven as well as for acceptance testing, the Robot Framework is one of the top Python test frameworks. Although it is developed using Python, it can also run on IronPython, which is .net-based and on Java-based Jython. Robot as a Python framework is compatible across all platforms—Windows, MacOS, or Linux.
Microservice architecture is a popular software design pattern that involves dividing a large application into smaller, independent services that can be developed, deployed, and scaled autonomously. Each microservice is responsible for a specific function within the larger application and communicates with other services via well-defined interfaces, often leveraging lightweight communication protocols such as REST or message queues.
Advantages of Microservice Architecture
Microservice architecture provides several advantages. Here are some benefits of using microservices:
From Facebook and Instagram to Yelp and Google Business, there are a dozen ways for organizations to maintain an online presence. But no matter how many profiles you create across these popular social media and review sites, your audience will want to visit your real home. The one not hosted by Google, Facebook, or Yelp.
I’m talking about your website. A website gives your business credibility. It’s a place to show off your brand, relay important information, answer FAQs, and publish SEO-rich articles to increase your visibility and value. But you only get a few seconds to make a positive impression when visitors arrive, so make sure it’s effective by using some of these nine modern website design trends.
1. Accessibility
Website accessibility—that is, making sure site elements like images, links, and even color schemes are kind to visitors with visual or other impairments—is more of a need than a trend. But it’s something that many businesses are only now starting to incorporate into their websites. The CDC estimates that one in four adults in the United States lives with a disability. That’s a quarter of your potential website audience!
How do you make your website more accessible to people with disabilities? Think about high-contrast viewing modes, keyboard navigation options, ARIA labels to provide invisible text descriptions on clickable fields for screen readers to read, meaningful alt text for screen readers describing your images, focus indicators, and video descriptions.
Patagonia
With high-contrast fonts and colors, descriptive links, and focus indicators on most buttons, the Patagonia website is already accessible to many. But if visitors need additional support, they can navigate to Patagonia’s Accessibility Statement page and Level Access page to download assistive technology.
Patagonia goes above and beyond the minimum considerations for accessibility.
Scope
One of our favorite examples of an accessible website is Scope, a non-profit organization that promotes disability equality in the UK. The website features bold colors, focus indicators, high-contrast fonts, and an accessibility button on the page’s top-left corner, where it’s easy for screen readers and people to find. According to its accessibility page, Scope scans its site for accessibility issues every four months and provides transparency about problem areas and recent updates.
With bright, bold, contrasting colors, focus indicators, and an accessibility button, Scope’s website is a great example of what to strive for.
2. Custom Illustrations
It’s not hard to find a website that features unique illustrations these days. Even SaaS companies like Notion, Todoist, GitHub, and Salesforce use custom imagery to highlight their brand and products. Custom graphics give websites a personal touch. They can be whatever you need to fit your brand’s personality: playful, somber, simple, or complex.
And they’ve never been easier to make. Tools like Adobe Illustrator help artists and graphic designers create custom vector-based illustrations, drawings, cartoons, and just about any type of artwork a website designer could want. Even those of us with limited design skills can try Adobe Illustrator. Or, you can hire professionals through sites like 99Designs and get something one-of-a-kind from an experienced designer.
Duolingo
Duolingo’s adorable illustrations make learning a new language seem easy and fun. Who wouldn’t want to follow the cute little owl on a new adventure? The images work to make the concept of learning another language much less intimidating.
Duolingo’s eye-catching illustrations help make the idea of learning a new language seem like the most fun challenge you’ll ever tackle.
Notion
Illustrations don’t have to be colorful to look good, though. The project management software company, Notion, embraces a black-and-white color scheme as part of its brand identity. The web illustrations reflect that choice.
Notion’s black-and-white illustrations make the bits of color in the website pop.
3. Full-Page Hero Images
Gone are the days of limiting your hero image to the upper marquee of a website. Countless websites use full-page hero images that make us want to enter the world on the other side of our screens. The best full-page hero images are layered with just enough text to get the viewer to scroll down or select a menu option.
Too much text, and the hero image gets obscured. Too little, and a viewer might not know what action the website wants them to take. As smartphone cameras continue to get more powerful and loading speeds keep improving, we predict this 2023 website trend will hold strong for years to come.
Ocean Conservancy
Full-page hero images should support your brand. In other words, avoid stock photos if you can. Take a look at the Ocean Conservancy’s captivating hero image. It makes you feel like you’re underwater with the sea turtle. Who wouldn’t want to help keep oceans healthy after viewing it?
The Ocean Conservancy hero image makes you feel like you’re under the sea.
Yelp
Yelp is another example of full-page hero images put to good use. Known for its local retailer and restaurant reviews, the company also wants to promote automotive, housekeeping, and painting services. Its rotating carousel of full-page header images showcases photos from business owners in each of these fields.
Crisp, authoritative text layered over an image of a clean house helps promote Yelp’s evolving review focus.
4. Playful Fonts
After three difficult years of pandemic-related stress, modern website design is leaning resolutely into an era of playfulness and personality. Fonts are no longer purely functional. With more font choices now than ever, people are picking typefaces that evoke a range of bold, beautiful feelings.
And with tools like Adobe Illustrator, it’s never been easier to create custom fonts if you’re up for the challenge. Either way, you can employ creative but still readable fonts to give your website a unique look.
CatScarf
CatScarf provides custom, comfortable, high-fashion scarves…for cats. It’s quirky. It’s fun. It’s a little bit serious. The fonts on the CatScarf website reflect these brand characteristics, striking a clever balance of elegance and playfulness.
The playful, serious, and elegant selection of typefaces on the CatScarf website work together to create an immersive brand experience.
The Met
Even though conventional wisdom says to use a maximum of three fonts on a single webpage, The Metropolitan Museum of Art ignores this. Instead, it proudly displays a variety of wildly different fonts. The Met is all about art, and art is bold, diverse, and complex all at once–just like the font choices on The Met’s website.
A sturdy sans serif font describing each exhibit ties the whole webpage together.
5. Card Layouts
2023 is the year of cards…at least when it comes to modern website design. Website cards are UI (user interface) units that come in square or rectangular shapes and contain bite-sized pieces of information. A website card can include several elements to display this information, such as a title, image, descriptive text, call-to-action button, link, or hashtag.
Sites like Pinterest have been using card layouts for a while, but more websites are adopting the trend for themselves these days. And why not? Cards are an easy way to fit lots of information on a page without overwhelming the viewer and provide a level of interactivity with your website.
The Met
As the nation’s most-visited museum and the largest art museum in the Americas, The Met has an overwhelming amount of information to share with its website visitors. But the site is anything but cluttered. Every bit of information is broken into image-centric cards, and each card is a link that leads the viewer to a whole new webpage.
The Met uses different sizes of cards to display key information and make it easy to click between web pages.
SurveyMonkey
On the SurveyMonkey website, cards act as buttons that guide web visitors to the perfect survey template. Each card has a simple illustration that helps you quickly understand what type of survey it links to. It’s a clean way of presenting several options to a site visitor without creating clutter or confusion.
These simple cards on the SurveyMonkey website make choosing a survey template quick and easy.
6. Background Videos
Modern website design is really embracing background videos instead of classic hero images since so many visitors have better internet connections or data transfer speeds via cell service. Have you noticed that a video will automatically start to play when you navigate to some sites? This puts you right in the center of the action and keeps you on the page. You can’t look away.
So, you stay on the site and keep watching the video—and then click on the text to learn more. It’s genius. A couple of years ago, background videos were limited to desktop versions of websites. But in 2023, most smartphones have the mobile network capacity they need to quickly load and play automatic background videos.
Playa Grande
I could stare at the automatic background video loop on the Playa Grande Golf & Ocean Club website for hours. The club is in the Dominican Republic. Each video clip showcases the activities you can do at the club while surrounded by the gorgeous turquoise waters of the Caribbean Sea.
The Playa Grande website uses background videos that make visitors want to book plane tickets immediately.
Beyond Indigo Pets
Beyond Indigo Pets, a content agency for veterinary websites, also uses a loop of background videos to highlight its services. Each clip shows a different animal turning its head to look at the camera. The overlaid text highlights the services Beyond Indigo offers, which are designed—you guessed it—to turn heads.
Who wouldn’t want to watch an infinite loop of adorable animals turning their heads to look at the camera?
7. Creative Cursors
Many web designers are embracing unique cursors to add value to their websites. Instead of featuring tiny arrows, hands, or magnifying glasses that we barely see because we’re so used to them, designers are choosing bold, creative cursors.
Some contain images or text that enrich the viewer’s experience. Others activate fascinating visual and UX effects. When done well, creative cursors keep web visitors on a page just a little bit longer—and make a page unforgettable.
Kite Festival
When you hover over the name of one of the musicians performing in the UK’s Kite Festival, your cursor will turn into a bright circle with a photograph of the musician inside. This helps personalize an otherwise unremarkable-looking list of names and gives each artist a slice of the spotlight.
The photo in the bright circle of your cursor changes as you hover over different names.
Advanced Team
Advanced Team is a boutique website design agency, and its creative cursor showcases the best of its design abilities by leaving a pattern in the wake of cursor movements. It’s so cool that I just want to sit at my laptop and create swirl patterns all day. Yes, that green swirl you see is the cursor moving across the page!
I highly suggest testing out this amazing cursor yourself.
8. Augmented and Virtual Reality
From face filters on Instagram to Home Depot’s 3D Augmented Reality feature, we’ve been using AR for a while. But the trend is only getting stronger in 2023, with sites refining and adding to their AR capabilities. Websites are also starting to implement Web VR, a type of virtual reality that allows you to step into immersive experiences with or without a VR headset.
Augmented and virtual reality can help us decide which paint colors to choose, which furniture to buy, and find places to explore. And it’s only going to get more sophisticated from here.
Google Earth
Google continues to add features and updates to Google Earth VR, a mixed-reality experience that lets you walk through Florence or fly through the Grand Canyon. You can enjoy some of the magic on your computer screen or strap on your headset for the full experience.
Use Google Earth VR to explore places you might never get to see in real life.
The Home Depot
The Home Depot introduced AR in 2015, but the technology gets better every year. You can now use the Home Depot app to visualize every detail of a build or remodel before making a single purchase.
The Home Depot’s AR feature helps you see how home decor products, paint colors, flooring, and furniture will look in your home, saving you time and money.
9. Chatbots
Chatbots are popping up—literally—on more and more websites every day. They’re particularly helpful on ecommerce or SaaS sites, where the friendly little AI-powered conversational agents can answer questions or connect you with a real human.
Whether you find them annoying or helpful, they’re here to stay. And they’re getting more capable, too. Instead of only being activated when you respond to them by typing a question, chatbot developers are starting to adopt voice-enabled technology.
Slack
Chatbot developers got smart. It’s harder than ever to make a chatbot say silly things by asking it random questions. The Slack chatbot, for example, asks you questions and provides a range of answers for you to choose from. You can’t just type a question, and you won’t need to.
The Slack chatbot helps you decide whether or not Slack is right for you.
Snatchbot
Tools like Snatchbot are making it easier for people who aren’t chatbot developers or experienced coders to include chatbots on their websites to field questions from visitors and connect them with salespeople. You can even create a Snatchbot chatbot that speaks in one of 60 languages.
SnatchBot helps you create a chatbot that speaks in English, Spanish, Hindi, Chinese, French, or another language.
Final Thoughts About Modern Website Design
If you’re designing a new website or reimagining a site you haven’t touched in years, consider incorporating some of these trends to bring it into the modern ages and vie for the attention of visitors better than your competitors.
Voice-activated chatbots can increase your website’s accessibility level. Background videos showcase the best things about your brand. Playful fonts and cursors help your content stick in the mind of your web visitors. And those are just a few basic examples of how to utilize the trends we’ve spotlighted in this article.
Wix is a popular website builder and can be a fantastic option to create a website, but it isn't the only option around. In fact, there are some aspects of Wix that many won't find so welcoming. As such, you're probably interested in exploring some Wix alternatives, so that you can compare them, and make the switch. Well, that's exactly what we're going to give you, so keep reading.
In the contemporary era of digitization, information reigns supreme and is an indispensable asset for almost every business venture. To capitalize on the potential of data, data science, and software engineering have emerged as key players in the technology industry. While these two fields are often used interchangeably, they are, in fact, distinct and necessitate different skill sets and expertise. This discourse will explore the intrinsic dissimilarities between data science and software engineering and their respective roles, responsibilities, and methodologies.
Data science is a multifaceted field focusing on mining, interpreting, and manipulating vast and complex data sets to draw meaningful insights and create predictive models. It encompasses various sub-disciplines, such as statistics, mathematics, machine learning, and programming.
