Top 9 Tips For Optimizing Images in 2021

The ‘need for speed’ is an essential item on every website’s bucket list these days. And why not? Enhanced speed is directly responsible for converting traffic into paying clients.

Anyone in any industry wishes to boost their website’s loading speed, providing an improved user experience. Plus, don’t forget that escalated site speeds also escalates the website’s ranking to more competitive spots on the search engine result pages and improves core web vitals. So, how can this need for speed be achieved? The answer is image optimization.

What is Image Optimization?

Image optimization is a process of delivering superior-quality images in the appropriate format, size, and resolution while keeping them at a compressed size. Image optimization, if done right, improves not only a website’s performance but also certain other metrics like:

Page loading speed;
SEO ranking;
Conversion rate;
User engagement;
User experience;
Resource download time.

However, the image optimization process can be accelerated for better efficiency if some modern tips are followed. ImageEngine, with its years of experience in the image optimization industry, has cherry-picked some tips that can help businesses in the year 2021 and beyond.

Tips for Perfect Image Optimization in 2021

In this article, the top five tips to optimize images have been outlined to help you maximize business opportunities. All the tips included are backed by comprehensive research and years of experience in the image optimization industry.

The Right Format Matters

Selecting the right image format matters a lot in the optimization process because every format is meant to serve a specific requirement.

JPEG: Best for still images, real-world images, and complex coloring;
PNG: Best for web images like logos and flat images;
GIF: Best for low-resolution images, animated graphics, small icons, and simple images — however, it is not advisable to go with GIF format but rather use mp4 or a webp instead;
TIFF: Best for high-quality and large-size print graphics;
WebP: A modern image format that offers superior compression while maintaining great quality.

Choosing the right format reduces bandwidth consumption for an improved webpage loading speed. However, a new format has joined the club: AVIF, that covers all the above image formats’ good qualities and surpasses even WebP while maintaining an excellent compression ratio. AVIF provides almost 50% savings in size when compared to JPEG format.

Serving images in the next generation formats like WebP and AVIF is a trending practice these days.

Go for Image Compression

Once the correct format has been selected, it becomes important to reduce the images’ size through a compression method. There are two methods of compressing images:

Lossless compression: In this compression method, all the unnecessary metadata linked with the images is removed without degrading the quality. The metadata can be erased safely while exhibiting the images on a website or application.

Lossy compression: In this compression method, the quality of the image is slightly reduced to accomplish a smaller size. The file size obtained in lossy conversion is lower than lossless compression, however, a naked human eye cannot highlight the difference between the original image and the lossy compressed image.

Never Skip the CDN

Image optimization and image CDNs are a match made in heaven. Website images not only need to be optimized but have to be delivered fast and easily as well. An optimized image is of no use if it cannot be transported quickly. An image CDN (Content Delivery Network) takes care of this need. It makes the rapid delivery of optimized images possible by reducing the distance between the online visitors and the servers.

The global image CDN also serves a ton of other benefits like:

Enabling fast global reach via cloud acceleration;
Audience segmentation (based on device viewport) becomes easy;
It saves many costs by eliminating the need to invest in separate server providers in different parts of the world;
Pulls down the load on the server to achieve reduced delivery cost;
Secure storage capacity.

The carefully engineered image CDN from ImageEngine distinguishes itself from the rest with its unique features listed below:

The images are optimized to be delivered 30% faster than other CDNs in the market;
It is easy to integrate and configure ImageEngine CDN;
The images are automatically optimized to the relevant format as per the user’s viewport size;
The images can be delivered in next-generation formats such as AVIF and WebP;
The images delivered have reduced size (irrespective of the format) and outstanding quality at the same time;
ImageEngine’s extensive global CDN network provides support for HTTP, HTTP/2, WAF, and DDoS protection.

Set-up Browser Caching

The “Leverage Browser Caching” warning displays on the Google PageSpeed Insights tool when there is no caching rule in the place, or the expiration time has been set too low. In simple terms, the warning is a suggestion to improve website speed.

Browser caching instructs the visitor’s browser to save some specific files on the visitor’s local system instead of downloading them repeatedly. For example, a visitor needs to download the logo image of a website on the first visit. However, after every subsequent visit, such a visitor would load the logo file from the website’s local cache, provided that the browser caching has been enabled. The result? Faster loading because the visitor is no longer required to get everything from the website’s server directly. Browser caching can be used for images and many other types of files like statistical resources and object data.

There are many ways to leverage browser caching but simply adding the following lines of code to the .htaccess file is the most effective one:

Browser caching stores the images for a decided interval of time for easy and quick accessibility. A custom timeline or industry standards can be followed for this purpose. The timeline in the above-shared code snippet is one year.

The .htaccess file can be found with the help of an FTP program for connecting to the root directory of the website’s server.

Disable Hotlinking

Hotlinking means when an individual or business copies the URL of an image, which belongs to another website, and embeds it on their website. This results in the image being displayed as if it was an owned content. Hotlinking is a next-door neighbor of copyright infringement, but despite this fact, the practice is widespread. In many cases, hotlinking is unintentional, but it can cost the original owner of the image some money. It can even affect the website’s performance if a drain of the server’s resources happens.

Optimize for Flaky Connections

If a website has a lot of content and rich images to offer, but a portion of the users visiting the website doesn’t have a reliable internet connection, then this portion of visitors would not convert. This situation is no different than any lost business opportunity. Not all website visitors have access to fast and reliable internet facilities; therefore, it is recommended to optimize image content for spotty connections.

One trusted way of optimizing the images for slow connections is compressing the images appropriately in real-time. However, even before compressing the images, it is important to determine the network speed of users visiting the page and then categorizing them into buckets based on connection types like 4G, 3G, 2G, or slow 2G.

But ImageEngine simplifies the whole compression process. It fetches and optimizes the images in the right format, dimension, and quality directly from the URL and then delivers such images on the website’s front-end via global image CDN.

Handling Responsive Images

A lot of traffic arrives from mobile devices, and as such, it is important to have the perfect strategy for responsive images.

If vector-based images are being used, then using SVG format would be a great way to optimize them for any viewport without worrying about sizes because SVG images are resolution-independent.
Using media queries for background images or images that have been produced via CSS is the best way to display smaller images to mobile devices.
For inline images, techniques like the srcset attribute or the picture element can be used.

srcset attribute: This attribute can be implemented on the img element for defining the images at different sizes so that the browser can select the best option based on the device characteristics like width.

picture element: This is best to be used if different images are required to be displayed based on the device’s display size.

All the aforesaid discussed options offer different ways of displaying the optimized images to visitors depending on how they view the website. MDN’s responsive image guide and Google developer’s image guide can be referred to for learning more about responsive images and using picture elements or srcset attributes.

Responsive Images

Images are required to be responsive to deliver the right optimal image for every screen size. It enhances the user experience and reduces load time. According to the browser or device in which images are viewed, images of different sizes are displayed, such as full-size, thumbnail, or featured images. To create a responsive image, you need to have different versions of the image.

The problem is to optimize a high-resolution image that looks great with details while displaying it on mobile devices; details can be missed, so instead of shrinking the image details, consider cropping or scaling down the image for mobile devices.

Advantages of responsive images:

Improve the page loading speed;
Increase your reach through smartphone responsive design;
Increase conversion and sales rate with consistent user experience;
Reduce load over the server and server memory;
Boost conversations.

Client Hints

The fundamental of Client Hints is simple — the client through a device sends the server some hints regarding the requirement. The server with responsibility serves them with the right resource according to the hint. For example, with hints, browsers ask the server for 600px images for the device layout — the image to be served based on the requested parameter. Even if the client informs that data saver mode is enabled, the server delivers identical images of a lighter version. The browser and server interact through Client Hints, the job becomes readable, shorter with the same functionality.

Client Hints with ImageEngine

ImageEngine delivers images with the required – width, DPR, and Data Saver. The responsive images are created based on client hints about width and DPR and later cover the Data Saver client hint.

Optimize Images For Retina Displays

Apple coined the term “retina displays,” which display clear and densely packed pixels to provide perfect vision from an appropriate viewing distance. Now, most smartphones and desktops deliver users a high crispy viewing experience. Apple with Retina squeezed four times the pixels into the same space to create a density of 326 pixels per inch (PPI), making the displays smooth.

Why Optimize Images for Retina?

The average screen pixel density is quite low, so the web-based standard images need to include 72 PPI to cover a certain height and width.

We need to maintain the appropriate density of pixels. Otherwise, the image will cram or get stretched. As a result, a fuzzy image is created with jagged edges that distract the viewer from your brand. To solve the problem, Retina class displays came into the role. They increased image resolution, optimized high pixel density in small space, and even displayed images decently over large screens.

People these days browse from a different device; most users access images from smartphones rather than desktops. So you need to optimize the image for Retina displays.

Wrapping it up

There are many tips and tricks to optimize images, but of all these tips, using a CDN has proven to be the most effective and long-term solution for many businesses all across the globe. Image CDNs automate the optimization process for a business to focus on its core activities properly. The good thing is that it is not all expensive to integrate image CDN. It is easy to get started with and generates the results in a short space of time.

Scaling Databases With EclipseLink And Redis

Actualités, Méthodes et organisation des process IT

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

2 Smartest Ways to Structure Sass

Actualités, Actualités

Sass – the extended arm of CSS; the power factor that brings elegance to your code.

With Sass, it is all about variables, nesting, mixins, functions, partials, imports, inheritance, and control directives. Sass makes your code more maintainable and reusable.

And now, I will show you how to make your code more structured and organized.

The organization of files and folders is crucial when projects expand. Modularizing the directory is necessary as the file structure increases significantly. This means structuring is in order. Here is a way to do it.

Divide the stylesheets into separate files by using Partials
Import the partials into the master stylesheet – which is typically the main.sass file.
Create a layout folder for the layout specific files

Types of Sass Structures

There are a few different structures you can use. I prefer using two structures — a simple one and a more complex one. Let’s have a look.

Simple Structure

The simple structure is convenient for a small project like a single web page. For that purpose, you need to create a very minimal structure. Here is an example:

_base.sass — contains all the resets, variables, mixins, and utility classes
_layout.sass — all the Sass code handling the layout, which is the container and grid systems
_components.sass — everything that is reusable – buttons, navbars, cards, and so on
_main.sass — the main partial should contain only the imports of the already mentioned files

Another example of the same simple structure is the following:

_core.sass — contains variables, resets, mixins, and other similar styles
_layout.sass — there are the styles for the header, footer, the grid system, etc
_components.sass — styles for every component necessary for that project, including buttons, modals, etc.
_app.sass — imports

This is the one I usually use for smaller projects. And when it comes to making a decision of what kind of structure to be used, the size of the project is often the deciding factor.

Why Use This Structure?

There are several advantages why you should use this organisational structure. First of all, the CSS files cache and in doing so, the need to download a new file for every new page visit is decreased. In this way, the HTTP requests decrease as well.

Secondly, this structure is much easier to maintain since there is only one file.

Thirdly, the CSS files can be compressed and thus decrease their size. For a better outcome, it is recommended to use Sass/Less and then do concatenation and minification of the files.

In case files become disorganized, you would need to expand the structure. In such a case, you can add a folder for the components and break it further into individual files. If the project broadens and there is a need for restructuring the whole Sass structure, consider the next, more complex pattern.

The 7-1 Patterned Structure

The name of this structure comes from 7 folders, 1 file. This structure is used by many, as it is considered to be a good basis for projects of larger sizes. All you need to do is organize the partials in 7 different folders, and one single file (app.sass) should sit at the root level handling the imports. Here is an example:

sass/
|
|- abstracts/
| |- _mixins // Sass Mixins Folder
| |- _variables.scss // Sass Variables
|
|- core/
| |- _reset.scss // Reset
| |- _typography.scss // Typography Rules
|
|- components/
| |- _buttons.scss // Buttons
| |- _carousel.scss // Carousel
| |- _slider.scss // Slider
|
|- layout/
| |- _navigation.scss // Navigation
| |- _header.scss // Header
| |- _footer.scss // Footer
| |- _sidebar.scss // Sidebar
| |- _grid.scss // Grid
|
|- pages/
| |- _home.scss // Home styles
| |- _about.scss // About styles
|
|- sections/ (or blocks/)
| |- _hero.scss // Hero section
| |- _cta.scss // CTA section
|
|- vendors/ (if needed)
| |- _bootstrap.scss // Bootstrap
|
- app.scss // Main Sass file

In the Abstract partial, there is a file with all the variables, mixins, and similar components.

The Core partial contains files like typography, resets, and boilerplate code, used across the whole website. Once you write this code, there is no further overwriting.

The Components partial contains styles for all components that are to be created for one website, including buttons, carousels, tabs, modals, and the like.

The Layout partial has all styles necessary for the layout of the site, i.e., header, footer.

The Pages partial contains the styles for every individual page. Almost every page needs to have specific styles that are to be used only for that particular page.

For every section to be reusable and the sass code to be easily accessible, there is the Section/Blocks partial. Also, it is important to have this partial so that you don’t need to search whether particular code is in the home.sass or about.sass files in the Pages partial.

It is a good idea to put each section in a separate .sass file. Thus, if you have two different hero sections, put the code in the same file to know that there you can find the code for the two sections. And if you follow this pattern, you will have the majority of files in this folder.

The Vendors partial is intended for bootstrap frameworks so, if you use one in your project, create this partial.

I recommend you use app.sass as the main folder. Here is how it should look:

// Abstract files
@import "abscracts/all"; // Vendor Files
@import "vendor/bootstrap.scss"; // Core files
@import "core/all"; // Components
@import "components/all"; // Layout
@import "layout/all"; // Sections
@import "sections/all"; // Pages
@import "pages/all";

Instead of having a lot of imports in the file, create an all.sass file in every folder. Each all.sass file should contain all the imports for that folder — and to make it more visible and understandable, create a main file.

Organisation

The biggest benefit of this structure is organisation.You always know where to check if you need to change something specific. For example, if you want to change the spacing on a Section/Block you go directly to the Sections/Blocks folder. That way, you don’t need to search in the folder to find the class in a file.

Facilitation

When the code is structured, the processes are promptly facilitated. They are streamlined and every segment of the code has their own place.

Final Words

Organizing code is essential for developers and together with all other skills, it is the most effective way to improve the functioning of the site. And even though there are multiple ways of organisation and different strategies, opting for simplicity helps you avoid the dangerous pitfalls. And finally, there is no right or wrong choice since everything depends on the developer’s work strategies.

12 Best Google Design & Development Tools

Actualités, Actualités

Google resembles an iceberg: there’s the part above the water we can see and use everyday; there’s also the part beneath the water, that we don’t see and know little about.

While many of us are concerned about the aspects of Google we don’t see — the parts that threaten our privacy, or monopolize the web — there’s no denying that Google offers some amazing products and tools, many of them free, all from the convenience of a single login.

Today we’re going to take a look at 12 tools from Google that really do bring something positive to the table.

1. Polymer

Polymer is an open-source JavaScript library from Google for building web applications using Web Components. The platform comes with a ton of libraries and tools to help designers and developers unlock the web’s potential by taking advantage of features like HTTP/2, Web Components, and Service Workers.

The main feature of Polymer is Web Components. With Web Components, you can share custom elements to any site, work seamlessly with any browser’s built-in elements, and effectively use frameworks of all kinds. Products like LitElement (a simple base class for creating fast, lightweight web components) and PWA Starter Kit make Polymer easy to use. If you like, you can build your app entirely out of Web Components.

2. Lighthouse

Google Lighthouse is an open-source, automated tool for improving the quality of web pages. The software allows you to audit web pages for performance, SEO, accessibility, and more. You can run Lighthouse using ChromeDevTools, directly from the command line, or as a Node module.

To use Lighthouse in Google Chrome, just go to the URL you want to audit (you can audit any URL on the web), open ChromeDevTools, and click the Audits tab. After you have run the audit, Lighthouse will give you an in-depth report on the web page.

With these reports, you will see which parts of your web page you need to optimize. Each report has a reference doc that explains why that audit is important and also shows you the steps you can take to fix it.

You can also use Lighthouse CL to prevent regression on your sites. Using Lighthouse Viewer, you can view and share reports online. You can also share reports as JSON or GitHub Gists.

Lighthouse also comes with a feature called Stack Packs that allows Lighthouse to detect what platform a site is built on. It also displays specific stack-based recommendations.

3. Google Analytics

Google Analytics is the gold standard of analytics services. Google analytics can be installed on your site for free with a small amount of JavaScript and allows you to see all kinds of details about your site visitors, like what browser they’re using, and where they’re from.

By using Google Analytics you can make decisions about your site based on science, and therefore be somewhat confident that the decisions you make will result in the outcome you are expecting.

4. Flutter

Flutter is Google’s UI toolkit for building natively compiled applications for mobile, web, and desktop from a single codebase. The toolkit is open source and free to use. The best part of Flutter is that it works with existing code.

The toolkit has a layered architecture that allows for full customization, which results in fast rendering and flexible designs. It also comes with fully-customizable widgets that allow you to build native interfaces in minutes. With these widgets, you will be able to add platform features such as scrolling, navigation, icons, and fonts to provide a full native performance on both iOS and Android.

Flutter also has a feature called hot reload that allows you to easily build UIs, add new features, and fix bugs faster. You can also compile Flutter code to native ARM machine code using Dart native compilers.

5. Google API Explorer

Google has a huge library of APIs that are available to developers but finding these APIs can be difficult. Google API Explorer makes it easy for developers to locate any API. On the Google API Explorer web page, you will see a complete list of the entire API library. You can easily scroll through the list or use the search box to filter through the API list.

The best part of Google API Explorer is that each link to a reference page comes with more details on how to use the API. API Explorer is an excellent way to try out methods in the Monitoring API without having to write any code.

6. Puppeteer

Puppeteer is a project from the Google Chrome team. The platform enables web developers to control a Chrome (or any other Chrome DevTools Protocol based browser) and execute common actions, much like in a real browser. Puppeteer is also a Node library and it provides a high-level API for working with headless Chrome. It is also a useful tool for scraping, testing, and automating web pages.

Here are some things you can do with Puppeteer: generate screenshots and PDFs of pages, UI testing, test Chrome Extensions, automate form submission, generate pre-rendered content, and crawl Single-Page Applications.

7. Codelabs

Google Developer Codelabs is a handy tool for beginner developers and even advanced developers who want to improve their knowledge. Codelabs provide a guided, tutorial, hands-on coding experience. Codelabs’ site is broken down into several tutorial sessions on different topics.

With the tutorials on Codelabs, you can learn how to build applications from scratch. Some of the tutorial categories include Augmented reality, TensorFlow, Analytics, Virtual Analytics, G Suite, Search, Google Compute Engine, and Google APIs on iOS.

8. Color Tool

Color Tool makes it easy for web designers to create, share, and apply colors to their UI. It also measures the accessibility level for any color combination before exporting to the palette. The tool comes with 6 user interfaces and offers over 250 colors to choose from.

The tool is also very easy to use. All you need to do is pick a color and apply it to the primary color scheme; switch to the secondary color scheme, and pick another color. You can also switch to Custom to pick your own colors. After you have selected all your colors, use the Accessibility feature to check if all is good before exporting it to your palette.

9. Workbox

Workbox is a set of JavaScript libraries and Node modules. The JavaScript libraries make it easy to add offline support to web apps. The Node modules make it easy to cache assets and offer other features to help users build Progressive Web Apps. Some of these features include pre-caching, runtime caching, request routing, background sync, debugging, and greater flexibility than sw-precache and sw-toolbox.

With Workbox, you can add a quick rule that enables you to cache Google fonts, images, JavaScript, and CSS files. Caching these files will make your web page to run faster and also consume less storage. You can also pre-cache your files in your web app using their CLI, Node module, or webpack plugin.

10. PageSpeed Insights

PageSpeed Insights is a handy tool from Google Developers that analyzes the content of a web page, then generates suggestions on how to make the page faster. It gives reports on the performance of a web page on both desktop and mobile devices. At the top of the report, PageSpeed Insights provides a score that summarizes the page’s performance.

11. AMP on Google

AMP pages load faster and also look better than standard HTML pages on mobile devices. AMP on Google allows you to enhance your AMP pages across Google. It is a web component framework that allows you to create user-first websites, ads, emails, and stories. One benefit of AMP is that it allows your web pages to load almost instantly across all devices and platforms hence improving the user’s experience.

12. Window Resizer

When creating websites, it is important that developers test them for responsive design – this is where Window Resizer comes in. Window Resizer is a Chrome extension that resizes the browser window so that you can test your responsive design on different screen resolutions. The common screen sizes offered are desktop, laptop, and mobile, but you can also add custom screen sizes.

Cache in Java With LRU Eviction Policy

Actualités, Méthodes et organisation des process IT

What a cache!

Introduction

LRU (or Least Recently Used) is a cache eviction strategy, wherein if the cache size has reached the maximum allocated capacity, the least recently accessed objects in the cache will be evicted. Also, the objects in the cache could be accessed by multiple threads in an application so is very important that the cache has a good synchronization mechanism in-built. This article describes the implementation of a Java-based cache with LRU eviction strategy, but fundamentally, this applies to any programming language.
