Construire le prochain Data Lakehouse : 10X Performance

Construire le prochain Data Lakehouse : 10X Performance

,

Construire le prochain Data Lakehouse pour obtenir une performance 10X plus rapide est un défi passionnant. Nous devons trouver des moyens innovants pour exploiter les technologies de données modernes.

Unification: La Nouvelle Paradigme du Data Lakehouse

unifying data, unifying analytics, and unifying governance.

En tant que scientifique informatique enthousiaste, je peux dire que le concept de data lakehouse est un paradigme révolutionnaire. Il a été défini par Bill Inmon il y a plus de 30 ans comme « une collection intégrée, non volatile et à temps variable de données à des fins de prise de décision ». Cependant, les premiers data warehouses étaient incapables de stocker des données hétérogènes massives, ce qui a conduit à la création des data lakes.

Aujourd’hui, le data lakehouse est une architecture de gestion de données ouverte dotée de puissantes capacités d’analyse et de gouvernance des données, d’une grande flexibilité et d’un stockage ouvert. Si je devais utiliser un seul mot pour décrire le data lakehouse de nouvelle génération, ce serait unification : unifier les données, unifier l’analyse et unifier la gouvernance.

Le data lakehouse est une solution idéale pour les entreprises qui souhaitent tirer parti de leurs données. Il permet aux entreprises d’accéder à des informations précieuses et d’utiliser des outils d’analyse avancés pour prendre des décisions plus éclairées. Grâce au data lakehouse, les entreprises peuvent facilement intégrer des données hétérogènes et obtenir des informations exploitables pour leurs activités. De plus, le data lakehouse offre une meilleure visibilité sur les données et une meilleure sécurité grâce à des fonctionnalités de codage avancées.

En conclusion, le data lakehouse est une solution innovante qui offre aux entreprises une meilleure gestion et une meilleure analyse des données. Il permet aux entreprises de tirer parti de leurs données pour prendre des décisions plus éclairées et améliorer leurs activités. Le data lakehouse est une solution idéale pour les entreprises qui cherchent à intégrer des données hétérogènes et à utiliser des outils d’analyse avancés pour améliorer leurs performances.

20 Best New Websites, July 2022

,

Welcome to our guide to the best new websites this month. If subtle, minimal sites are your thing, either look away now or prepare to have your preconceptions challenged because this month, we are going maximalist.

Lots of elements fill up the screen, lots of color, lots of big fonts, lots of illustration, and plenty of in-your-face personality. This is a tricky style to get right: if elements are not chosen and placed well, the result is simply annoying clutter. If done well, the result can be impactful and memorable.

[And Happy Independence Day to all of our American readers!]

screenagers & the incredible machine

screenagers & the incredible machine’s site puts illustration front and center, creating a look that evokes various mystic ideas. It sounds strange, but it works.

Anna Jóna

This prelaunch teaser site for Anna Jóna café and cinema has an elegant yet modern feel.

Hardpops

This site for Hardpops (alcoholic) ice pops takes its cue from the product flavors, and the bright, fruity colors give it a real zing.

Daniel Spatzek

Daniel Spatzek’s portfolio site takes the rules-are-made-to-be-broken approach. The result has attitude and a nice touch of humor.

Ander Agency

Plenty of color, large type, and illustration make a bold statement for Ander Agency’s single-page site.

Pretty Damn Quick

Colorful illustration on this site for Pretty Damn Quick’s Shopify app creates an impression of friendliness about the company and ease of use of the product itself.

Know Your Beetle

Know Your Beetle is a showcase page for Kaploom creative studio. Color and type combinations make a big impact.

WTFFF

While many of the sites featured here have a sense of fun about them, WTFFF tackles a somber subject: online sexual abuse and harassment. Artwork and audio create an immersive experience in which five young people share their experiences with the aim of helping others.

BelArosa Chalet

Full-screen illustrations with a hint of vintage style create an ideal impression of what future guests can expect from the currently under construction BelArosa Chalet.

Paradam

The color scheme on the Paradam site is on the pastel end of the scale, but there is still lots going on to entrance the eye.

Tilton Group

The scrolling color panels on the Tilton Group site are a thing to behold.

Fresco

Fresco uses a standard layout design, but the colors and quarter-circles instantly lift it.

Museum of Pink Art

Museum of Pink Art is an immersive experience celebrating the color pink. Undoubtedly worth a virtual wander around.

Icons by Menu

OK, this somewhat more minimalist site slipped through the net, but Icons by Menu is so pleasing to look at and use that we had to include it.

GlareDB

With an illustration that could be ideally at home on an Arthur C. Clarke book jacket and that rich, deep red background, this site for Glare DB is a world away from what might be expected.

Alex Beige

While the overall style and accent illustrations are pleasing on Alex Beige’s site, the Our Team section is guaranteed to raise a smile and stick in the user’s mind.

Snickerdoodle

Careful spacing means busy elements (like on scroll animated illustrations) don’t become overwhelming on the Snickerdoodle site.

Grisly’s Cosmic Black

The site for Grisly’s Cosmic Black is fun, bright, and joyful. Plus, it’s nice to see an alcohol site going a bit further than the usual ‘drink responsibly’ and actually providing helpful links.

The Perennial

Not just floorplans and (lots of) images, but virtual walkthroughs too. The Perennial doesn’t feel like a standard office building.

Using Micro-Interactions to Drive UX

,

Micro-interactions effectively communicate brand identity and ethos while strengthening ties with the customer. These habit-forming tools make for a fun and seamless user experience. Facebook’s ‘likes’ and Tinder’s ‘swipes’ are two classic examples. 

Micro-interactions originated with the need to guide customers who had hit a snag while using a service or a product. The goal was to ease customers into being more product-savvy via subtle reassurance and feedback. Micro-interactions are now employed by everything from washing machines, to coffee makers.

Along with feedback, prompts, and recommendations, they can also present customers with an appealing visual reward upon finishing a task. When used optimally, micro-interactions drastically enhance the navigation and simplify how users interact with sites and apps.

How Micro-Interactions Work

Here are the four structural elements to a simple micro-interaction: triggers, rules, feedback, and loops. Every micro-interaction has a significant component to organize the operational cycle. It lets you control feedback and runs, so the users understand the consequences of their performance and feel motivated to follow through.

Triggers

This feature begins micro-interactions of both the user-initiated (prompted by user) and system-initiated (driven by the system) kind. For example, a click, scroll, swipe, tap, and pull are common triggers that users carry out. So making a payment, booking a cab, and clicking or tapping on the hamburger menu all fall under this category. On the flip side, the user’s alert prompt upon entering a wrong password is a classic system-generated trigger. 

Rules

This element determines what happens after the user sets a prompt into motion via tapping, clicking, scrolling, or swiping. Rules refer to the fact that apps decide the triggers that users employ — Tinder’s ‘swipe’ feature illustrates this point. These rules gradually become a habit-forming action that users get accustomed to while regularly engaging with an app.

Feedback

During this process stage, the system informs the user via auditory, visual, or haptic cues. It engages the users and encourages them to proceed further in their process. For example, the progress bar of a download, the visual representation of steps cleared in a circle, or the visual, aural, and tactile indication upon the success or failure of payment are all a part of the feedback mechanism.

Loop/Modes

This final stage entails tiny meta-rules of the process and determines the frequency and duration. A classic example from an ecommerce app is the ‘Buy Now’ transformed to ‘Buy Another’ Before the user loses interest in the app, the app typically uses such a loop to get them to re-engage with the app. 

How to Use Micro-Interactions

We’ve established that micro-interactions are fabulous, but not every UX interaction on your app or site needs one throughout the wireframe. Overusing this tool could saturate the overall creative experience your design may want to offer. Worse, it might even end up confusing the information hierarchy. It undermines the design and unbalances the user experience of discomfort and irritability. So it’s crucial to know when exactly to use them.

Let’s find out how few quick tips on micro-interactions can elevate and humanize your mobile user experience:

  • Swipe right or left: A signature move made entirely on swiping micro-interaction featured in the famous Tinder app. Swiping is an easier action than clicking or tapping.
  • Call-to-action:  As part of the last step during payment or order, place a ‘Confirm Order’ or ‘Book Now’ prompt, which gives the task a sense of urgency. As a result, having acted on it feels like a minor achievement. 
  • System status: Your app user wants to know what’s happening. System status lets them know they are moving in the right direction and helps avoid confusion. Sometimes, users even run out of patience while uploading a picture, downloading a file, or filling up the registration form.
  • Classic notifications: Users need a quick reminder of products selected/wishlist in their abandoned cart with a reduced attention span. A simple notification can nudge them toward finalizing the purchase. 
  • Button animation: Animated buttons are not only cute, but they also help users navigate the mobile app swiftly. Try out attractive colors, fonts, sizes, shapes, and clipart elements corresponding to the animation and create that cool button to pop up when tapped or hovered on. 
  • Animated text inputs:  A simple process of a likable element like zooming in while entering data into a form or filling up card details for payment can enhance the user experience.
  • Reward an achievement:  Especially true for educational and health apps, micro-interactions celebrating big and small milestones with a badge or a compliment of encouragement can strengthen a user’s engagement with the app. 

Benefits of Micro-Interactions

  • Brand communication: A successful brand ensures that the transmission to the buyer is engaging, positive, and hassle-free. When micro-interactions show a process status clearly, it creates and reinforces a positive image for your brand.
  • Higher user engagement: Experts say micro-interactions engage users better. These tiny elements subconsciously create the urge to keep interacting with your app. For example, each push or nudge notification acts toward redirecting your customers back to your app.
  • Enhanced user experience: From shopping to banking to traveling to learning to staying healthy, there’s an app for everything. A wide range of activities elevates the overall user experience and stays ahead in the game. Micro-interactions can work that magic for your brand. 
  • Prompt feedback: It’s frustrating not to know what’s happening behind the blank screen, especially during a purchase. Instant feedback via visual, sound, or vibrating notifications makes for a pleasant user experience. 
  • Visual harmony: Micro-interactions initiated even with a tap, swipe, typing, or scrolling are all a part of the UX design’s overall appeal. The trick is to keep all the interface elements in perfect sync with the app’s visual features.

Micro-Interaction Best Practices

Here are a few basic principles you should follow when you introduce a micro-interaction to the user experience.

1. Keep it simple, stupid (KISS)

KISS is a famous design principle that becomes even more important in the case of micro-interactions. The goal is to make the user journey delightful and not be a distraction.

2. Keep it Short

It has ‘micro’ in the name itself. But, again, micro-interactions aren’t supposed to be show stars, and a lengthy micro-interaction only distracts the user. 

3. Pick the Right Place

You should always consider the options carefully before choosing the spot for any micro-interaction. The widely used user-interaction designs are popular for a reason. Many people have already approved them, so you can safely continue with them. The use of micro-interaction should also sit well with your brand image. 

See also if the placement of a micro-interaction is reaching your ideal customer or not. And even consider whether you need a micro-interaction to begin with. 

And That’s a Wrap!

As UX designers, we can profoundly impact the overall design of sites and apps, the user’s journey, their interactions with our product/service, their connection with the brand, and the ease of doing a transaction.

We want customers to connect to our brand, love our products, and experience our exceptional customer service. But most of all, we want to earn their trust and loyalty.

7 Worst Fails in Email Marketing

,

The email channel is known for multiple advantages. It is convenient to implement practically, offers many options, and has a fantastic ROI of up to 4200%.

But we also face problems, the most disappointing of which is people ignore emails, not performing the desired action, or worst of all unsubscribing. Why does it happen?

The web is constantly progressing. It offers many tools like modern HTML template builders, ESP services, and other digital assistants that help us at all stages. But even the best tools are not enough; the secret of success still rests with us.

In this post we’ll cover the 7 cardinal sins of email marketing, to help you avoid them.

1. Being Too Late

I can define this mistake as probably the worst. It’s worse than broken links, incorrect dates, or prices. Even more harmful than ugly design.

We lose a lot when postponing email strategy implementation. Beginners often focus all their attention on the content, social media activities, SEO issues… All that is important, right. But ignoring email campaigns is a hard fail.

Thousands of visitors never come again to your website. In other words, they leave the very first levels of the marketing funnel. While regular emailing keeps them engaged and prevents churn.

So delays here are only profitable for competitors. Don’t wait until you collect “enough” contacts. Start as soon as possible. 

Frequency matters too. Don’t bomb people with emails; it annoys and causes unsubscribes. Email frequency is an individual parameter depending on many factors.

2. Disregarding Clients’ Expectations

A fundamental axiom: people unsubscribe when emails are irrelevant. The same goes for neglected expectations. Even the best content with next-gen features won’t save the situation.

I mentioned the email frequency a bit above. Notice that if you announce the weekly emails but send them every day, this is an example of ignoring expectations. Be honest with readers.

Another typical issue is off-topic. If your subscribers are waiting for content related to smartphones, send them newsletters about smartphones, not dresses or domestic turtles :)

But in some cases, getting off-topic can be good. It all depends on the target audience, actual situation, and communication style. 

3. Bad Segmentation 

Once again, relevance is vital. So we must avoid generic emails. Instead, especially if your contact list is extensive enough, apply all the possible parameters: age, gender, location, customers history, etc.

Where to get the respective data? A typical solution is to use update preferences forms in emails or on the website. Let clients choose the topics that are interesting for them.

Use surveys, sign-in forms, AI-based techniques of segmentation… Smart algorithms are great helpers that track clients’ behavior and then process the data for segmentation purposes. 

The better we know our subscribers, the deeper we segment the contact list. It allows sending precisely targeted newsletters to respective segments.

4. Insufficient Personalization 

As Hubspot stats say, personalized emails’ open rate is 26% higher, and their click-through rate is 14% better. But even besides index data, poor personalization is just nonsense today.

Clients are looking for content that matches their preferences, so marketers have to consider these expectations. Segmentation and dynamic range are essential here, but they are not the only techniques.

Everything is much more sophisticated here, in addition to personalized subjects and content. Another solution is to generate recommendations that include the previously browsed products.

AI-powered automation comes to help. Machines will upgrade the classical personalization to the next level called hyper-personalization.

5. Underestimating Mobile-Friendliness 

It’s simply unacceptable to send non-responsive emails today. With so many people opening email on different devices, this is a huge fail.

The modern world is full of gadgets and devices. Email has been opened on smartphones more frequently than on desktop PCs and notebooks in recent years. Up to 70% of readers will read messages on mobiles very soon. No wonder that responsivity turned into a mobile priority.

Regarding layout and design, there are no problems: modern template editors are featured with automated responsivity. But mobile-first means not only layout/design adjustment for mobiles, full-width buttons, or larger fonts. We have to work with content too. Don’t overwrite text remember that recipients read inbox emails on the run. 

Just imagine yourself reading emails in the cafe or cab. And ask yourself: is everything convenient? Would you take the desired action on the run?

6. Non-Professional Approach 

People are quite skeptical of new brands. We need to do our best to attract them. So everything must be done professionally.

The best solution: be a perfectionist. If newsletters look amateurish, they are likely to repel.  

Being amateurish will also ruin your brand identity and reduce customers’ trust. Pay close attention to design, stick to your corporate style, analyze each detail in the context of overall harmony.

7. Overlooking Tests and Improvements 

Testing is vital. Before sending an email campaign, check it via Litmus or Email on Acid to be sure that message looks just as planned. These tools allow testing email rendering by +90 combinations of email clients, devices, and OS.

Knowledge is power. Always try and test your marketing strategies. Are you satisfied with your actual performance? Run A/B tests and focus on the most significant wins and failures. 

Summing Up

Of course, threats are not limited to these seven failures. The last piece of advice: never ignore trends. 

Accessibility? Don’t forget about clients with special requirements. Get whitelisted and incorporate these technologies in your campaigns.

And constantly strive for perfection. With this doctrine, you’ll win!

WordPress Website Analysis: Before & After ImageEngine

,


WordPress is by far the world’s most popular CMS. Not only does it dominate the CMS market with a 64% market share, but it also powers 39.6% of all websites. It has taken the internet by storm by democratizing the web for all. Now, anyone can build, manage, and host a successful website without needing a college degree or coding expertise.

However, while WordPress is great at managing many technical aspects, it still can’t do everything for you. Built mostly on PHP, there are often concerns regarding how performant WordPress is. And, with performance impacting everything from bounce rates to SEO rankings to conversions, it’s something that should be on your radar too.

If you don’t know it yet, images are one of the main causes of slow-loading websites. In recent years, WordPress has stepped up its efforts to try and help users with image optimization out-of-the-box.

Still, as we’ll show, it’s not a total solution, and there is still plenty you can do to deliver better experiences on your WordPress website through image optimization.

What is WordPress Image Optimization? Why is it Important?

Simply put, image optimization is anything you do to make images load faster on your website pages. Almost all websites that use images can benefit from some form of image optimization, even those using WordPress.

Why?

Well, performance is a hugely significant factor when it comes to the competitiveness of your website today.

Google has also made performance an increasingly important factor when it comes to SEO rankings. In fact, performance is a direct ranking signal that carries significant weight.

Google’s Page Experience Update that went live in 2021 has been the biggest move in that direction yet. Soon, Google might even use visual indicators in SERP results to distinguish high-performing websites from the rest.

In Google’s own words, “These signals measure how users perceive the experience of interacting with a web page and contribute to our ongoing work to ensure people get the most helpful and enjoyable experiences from the web.”

So, Why Should We Target Images For Performance Optimization?

According to Google, images are the largest contributor to page weight. Google has also singled out image optimization specifically as the factor with the most untapped potential for performance optimization.

This problem isn’t going away soon. According to data by the HTTP Archive, there are roughly 967.5 KB bytes of image data on desktop web pages and 866.3 KB of image data on mobile pages. This is an increase of 16.1% and 38.8%, respectively, over the last five years.

Thanks to popular e-commerce tools like Woocommerce, it’s estimated that up to 28% of all online sales happen on WordPress websites.

And don’t forget, images are both a key part of conveying information to the user and integral to the design of your website. If they take significantly longer to load than your text, for example, it will negatively impact the user experience in a variety of ways.

In summary, optimized images help your WordPress website by:

  • Improving user satisfaction.
  • Improving various traffic metrics, like bounce rates, time-on-page, etc.
  • Boosting your SEO rankings.
  • Contributing to higher conversions (and sales).

How Does Image Optimization in WordPress Work?

WordPress is so popular because it’s a CMS (content management system) that allows anyone to build, design, and manage a website without any coding or advanced technical experience. Advanced features can be installed with just a few clicks, thanks to plugins, and you rarely have to touch the code behind your website unless you want to make some unique modifications.

In short, using a CMS like WordPress shields you from many of the day-to-day technicalities of running a website.

WordPress Image Optimization: What It Can Do

As we mentioned, one of the main reasons WordPress is so popular is because it takes care of many of the technical aspects of running a website. With that in mind, many think that WordPress should also automatically take care of image optimization without them having to get involved at all.

Unfortunately, that’s not really the case.

True, WordPress does offer some built-in image optimization. Whenever you upload an image to WordPress, it currently compresses the quality to about 82% of the original (since v4.5).

In v4.4, WordPress also introduced responsive image syntax using the srcset attribute. This creates four breakpoints for each image you upload according to the default WordPress image sizes:

  • 150px square for thumbnails
  • 300px width for medium images
  • 768px max-width for medium_large images
  • 1024px max-width for large images.

Here you can see an example of the actual responsive syntax code generated by WordPress:

<img loading="lazy" src="https://bleedingcosmos.com/wp-content/uploads/2021/12/33-1024x683.jpg" alt="" class="wp-image-9" width="610" height="406" srcset="https://bleedingcosmos.com/wp-content/uploads/2021/12/33-1024x683.jpg 1024w, https://bleedingcosmos.com/wp-content/uploads/2021/12/33-300x200.jpg 300w, https://bleedingcosmos.com/wp-content/uploads/2021/12/33-768x512.jpg 768w, https://bleedingcosmos.com/wp-content/uploads/2021/12/33-1536x1024.jpg 1536w" sizes="(max-width: 610px) 100vw, 610px">

Depending on the screen size of the device from which a user visits your webpage, WordPress will let the browser pick the most appropriately sized image. For example, the smallest version for mobile displays or the largest for 4K Retina screens, like those of a Mac.

While this may seem impressive, it’s only a fraction of what can be achieved using a proper image optimization solution, as we’ll show later.

Lastly, WordPress implemented HTML native default lazy loading for all images starting with version 5.5.

So, in short, WordPress offers the following image optimization capabilities baked-in:

  • Quality compression (limited)
  • Responsive syntax (up to 4 breakpoints)
  • Lazy loading

WordPress Image Optimization: What it Cannot Do

There are other issues many have with both the implementation of image compression and responsive syntax as it’s used by WordPress. This leads to some users even purposefully deactivating WordPress’ built-in image optimization so they can fully take control of it themselves.

Here are some of the reasons why:

  • WordPress uses a very basic form of quality compression. It does not use advanced technologies like AI and machine learning algorithms to compress images while maintaining maximum visual quality. It’s also lossy compression, so the quality is lost for good. You can clearly see the difference between an original HD image and the compressed version created by WordPress.
  • WordPress only compresses most images by up to 20%, while advanced image optimization tools can reduce all image sizes intelligently by up to 80%.
  • Responsive syntax can provide significant performance improvements over simply uploading a single HD image to be served on all devices and screens. However, it’s still only limited to a set number of breakpoints (typically 3 or 4). Since it’s not dynamic, a whole spectrum of possible image sizes is not created or used.
  • Responsive syntax code is not scalable and can quickly lead to code that’s bloated, messy, and hard to read.
  • WordPress doesn’t accelerate image delivery by automatically caching and serving them via a global CDN, although this can be done using other tools.

Another important optimization feature that WordPress does not have is auto-conversion to next-gen image file formats. Different image formats offer different performance benefits on different devices. Some formats also enable higher levels of compression while maintaining visual fidelity.

Next-gen formats like WebP, AVIF, and JPEG-2000 are considered to be the most optimal formats on compatible devices. For example, until recently, WebP would be the optimal choice on Chrome browsers, while JPEG-4000 would be optimal on Safari browsers.

However, WordPress will simply serve images in the same formats in which they were originally uploaded to all visitors.

How to Measure the Image Performance of a WordPress Website?

As the undisputed king of search engines, we’ll base most of our performance metrics on guidelines established by Google.

Along with its various performance updates, Google has released a number of guidelines for developers as well as the tools to test and improve their websites according to said guidelines.

Google introduced Core Web Vitals as the primary metrics for measuring a web page’s performance and its effect on the user experience. Thus, Core Web Vitals are referred to as “user-centric performance metrics.” They are an attempt to give developers a testable and quantifiable way to measure an elusive and abstract concept such as “user experience.”

Combined with a number of other factors, Core Web Vitals constitute a major part of the overall page experience signal:

You can find a complete introduction to Core Web Vitals here. However, they currently consist of three main metrics:

  • LCP (Largest Contentful Paint): The time it takes the largest above-the-fold element on your page to load. This is typically a full-sized image or hero section.
  • FID (First Input Delay): The delay from the moment a user first interacts with an element on the page until it becomes responsive.
  • CLS (Cumulative Layout Shift): The visual stability with which the elements on a page load.

Here is an illustration of how these metrics are scored:

While these are the three most important metrics to optimize, they are not the only ones. Google still measures other metrics like the FCP (First Contentful Paint), SI (Speed Index), as well as the TTFB (Time to First Byte), TBT (Total Blocking Time), and TTI (Time to Interactive).

A number of these metrics are directly affected by the images used on your web pages. For example, LCP, FCP, and SI are direct indicators of how fast the content of your web page loads and depends on the overall byte size of the page. However, it can also indirectly affect FID by keeping the main thread busy with rendering large amounts of image content or the perceived CLS by delaying the time it takes large images to load.

These metrics apply to all websites, whether they are custom-made or built using a CMS like WordPress.

When using tools like Lighthouse or PageSpeed Insights, you’ll also get scored based on other flags Google deems important. Some of them are specific to images, such as properly sizing images and serving images in next-gen formats.

If you only use built-in WordPress image optimization, you’ll get flagged for the following opportunities for improvement:

Some of the audits it will pass, however, are deferring offscreen images (lazy loading) and efficiently coding images (due to compression):

A Better Way to Optimize WordPress Images: ImageEngine

Billions of websites are all vying for prime real estate on Google SERPs, as well as the attention of an increasingly fussy internet-using public. Every inch matters when it comes to giving your website a competitive advantage.

So, how can you eliminate those remaining performance flags and deliver highly optimized images that will keep both your visitors and Google happy?

Sure, you could manually optimize images using software like PhotoShop or GIMP. However, that will take you hours for each new batch of images. Plus, you still won’t benefit from any automated adaptive optimization.

A more reasonable solution in today’s fast-paced climate is to use a tool developed specifically for maximum image optimization: an image CDN like ImageEngine.

ImageEngine is an automated, cloud-based image optimization service using device detection as well as intelligent image compression using the power of AI and machine learning. It can reduce image payloads by up to 80% while maintaining visual quality and accelerating delivery around the world thanks to its CDN with geographically dispersed PoPs.

Why is ImageEngine Image Optimization Better Than WordPress?

When making a head-to-head comparison, here are the reasons why ImageEngine can deliver better performance:

  • Device Detection: ImageEngine features built-in device detection. This means it picks up what device a visitor to your website is using and tailors its optimization strategy to what’s best for that specific device.
  • Client hints: By supporting client hints, ImageEngine has access to even more information regarding the device and browser to make better optimization decisions.
  • Next-gen formats: Based on optimal settings, ImageEngine automatically converts and serves images in next-gen formats like WebP, AVIF, JPEG2000, and MP4 (for GIFs).
  • Save data header: When a Chrome user has save-data mode enabled, ImageEngine will automatically compress images more aggressively to save on data transfer.
  • CDN with dedicated edge servers: ImageEngine will automatically cache and serve your optimized image assets using its global CDN. Each edge server has device awareness built-in to bring down latency and accelerate delivery. You can also choose to prioritize specific regions.

So, the key differentiator is that ImageEngine can tailor optimizing images for what’s optimal for each of your visitors. ImageEngine is particularly good at serving mobile visitors thanks to WURFL device detection, which can dynamically resize images according to most devices and screen sizes in use today. As of now, this is a completely unique capability that none of its competitors offer.

It allows for far better and more fine-tuned optimization than WordPress’ across-the-board approach to compression and responsive syntax.

If you want, you could turn off WordPress responsive syntax and compression, and you would still experience a performance increase using ImageEngine. However, ImageEngine also plays nice with responsive syntax, so it’s not completely necessary unless you want to serve the highest-fidelity/low-byte-size images possible.

How Does ImageEngine Work with WordPress?

The process ImageEngine uses to integrate with WordPress can be broken down into a few easy steps:

  • Sign up for an ImageEngine account: ImageEngine offers three pricing plans depending on the scale and features you need as well as a no-commitment 30-day free trial.
  • Specify your image origin: This tells ImageEngine where to find the original versions of your images. For a WordPress website, you can just use your domain, e.g., https://mywordpresswebsite.com. ImageEngine will then automatically pull the images you’ve uploaded to your WordPress website.

  • Copy the Delivery Address: After you create an account and specify your image origin, ImageEngine will provide you with a Delivery Address. A Delivery Address is your own unique address that will be used in your <img> tags to point back to the ImageEngine service. Delivery Addresses may be on a shared domain (imgeng.in) or customized using a domain that you own. A Delivery Address typically looks something like {random_string}.cdn.imgeng.in. If your images are uploaded to the default WordPress folder /wp-content/uploads/, you can access your optimized images from ImageEngine simply by changing your website domain. For example, by typing {imageengine_domain}.cdn.imgeng.in/wp-content/uploads/myimage.jpg into your browser, you’ll see the optimized version of that image. Just press the copy button next to the Delivery Address and use it in the next step configuring the plugin.

  • Install the ImageEngine Optimizer CDN plugin: The plugin is completely free and can be installed just like any other plugin from the WordPress repository.
  • Configure and enable ImageEngine Plugin in WordPress: Just go to the plugin under “ImageEngine” in the main navigation menu. Then, copy and paste in your ImageEngine “Delivery Address,” tick the “Enabled” checkbox, and click “Save Changes” to enable ImageEngine:

Now, all ImageEngine basically does is replace your WordPress website domain in image URLs with your new ImageEngine Delivery Address. This makes it a simple, lightweight, and non-interfering plugin that works great with most other plugins and themes. It also doesn’t add unnecessary complexity or weight to your WordPress website pages.

ImageEngine vs Built-in WordPress Image Optimization

So, now let’s get down to business by testing the performance improvement you can expect from using ImageEngine to optimize your image assets.

To do this test, we set up a basic WordPress page containing a number of high-quality images. I then used PageSpeed Insights and the Lighthouse Performance Calculator to get the performance scores before and after using ImageEngine.

Importantly, we conducted this test from a mobile-first perspective. Not only has mobile internet traffic surpassed desktop traffic globally, but Google themselves have committed to mobile-first indexing as a result.

Here is a PageSpeed score using the Lighthouse calculator for WordPress with no image optimization:

As we can see, both Core Web Vitals and other important metrics were flagged as “needs improvement.” Specifically, the LCP, FCP, and TBT. In this case, both the LCP and FCP were a high-res featured image at the top of the page.

If we go to the opportunities for improvement highlighted by PageSpeed, we see where the issues come from. We could still save as much as 4.2s of loading time by properly resizing images and a further 2.7s by serving them in next-gen formats:

So, now let’s see how much ImageEngine can improve on that.

The same test run on my WordPress website using ImageEngine got the following results:

As you can see, we now have a 100 PageSpeed score. I saved roughly 2.5s on the SI (~86%) as well as roughly 1.7s on the LCP (~60%). There was also a slight improvement in the FCP.

Not only will you enjoy a stronger page experience signal from Google, but this represents a tangible difference to visitors regarding the speed with which your website loads. That difference will lead to lower bounce rates, increased user satisfaction, and more conversions.

There was also a 53% overall reduction in the total image payload. This is impressive, considering that it’s on top of WordPress’ built-in compression and responsive syntax.

Conclusion

So, as someone with a WordPress website, what can you take away from this?

Well, first of all, WordPress does feature some basic image optimization. And while not perfect, it should help you offer reasonable levels of performance, even if you use a lot of image content.

However, the caveat is that WordPress applies aggressive, across-the-board compression, which will lead to a noticeable reduction in visual quality. If you use WordPress for any type of website where premium quality images are important, this is a concern — for example, as a photography portfolio, exhibition, or image marketplace like Shutterstock.

By using ImageEngine, you can reduce image payloads and accelerate delivery even further without compromising too harshly on visual quality. What’s more, ImageEngine’s adaptive image optimization technology will provide greater improvements to more of your visitors, regardless of what device(s) they use to browse the web.

Whether or not you still want to use WordPress’ built-in optimizations, ImageEngine will deliver significant improvements to your user experience, traffic metrics, and even conversions.

Plus, true to the spirit of WordPress, it’s extremely simple to set up without any advanced configuration. Just sign up for ImageEngine in 3 easy steps, install the plugin, integrate ImageEngine by copy/pasting your image domain, and you’re good to go.

Inspecting Joins in PostgreSQL

,

Man on the computer.

Introduction

Relational databases distribute their data across many tables by normalization or according to business entities. This makes maintaining a growing database schema easier. Real-world queries often span across multiple tables, and hence joining these tables is inevitable.

PostgreSQL uses many algorithms to join tables. In this article, we will see how joins work behind the scenes from a planner perspective and understand how to optimize them.

How COVID Changed the Way We Work With SQL

,

Article Image Life was normal until 2020’s monstrously bad news – Covid – came around. Developers got out of bed, then marched to the office to crunch code as they always do. While inside of the office, they reviewed their goals, played with Git, interacted with their colleagues over a cup (or two) of coffee, and built products relevant to the functionality of the company. Many developers also had side-projects that they would go home and work on during their free time as their hobby.

While in the office, developers would be busy regurgitating code – web developers, for example, would work with PHP, SQL, CSS, Javascript, and its libraries (say, jQuery). Meanwhile, database administrators would think deeply about the performance of their database instances (they would take care of indexing and normalizing their data, or work with big data sets, etc.). Once the code was complete, they’d document it and push it over to GitHub.
