Artificial intelligence which gives machines the ability to think and behave like humans are gaining traction since the last decade. These features of artificial intelligence are only there because of its ability to predict certain things accurately, these predictions are based upon one certain technology which we know as machine learning (ML). Machine learning as the name suggests is the computer’s ability to learn new things and improve its functionality over time. The main focus of machine learning is on the development of computer programs that are capable of accessing data and using it to learn for themselves. 

To implement machine learning algorithms, two programming languages, R and Python for machine learning are normally used. Generally, selecting features for training data on machine learning in python is a very complex and technical process. But here we will go over some basic techniques and details regarding what is machine learning and how it works. So, let us start by going into detail regarding what ML is, what feature selection is and how can one select feature using python.

As you already know, TestNG or Test Next Generation is one of the most frequently used automation testing frameworks in Java. Inspired by JUnit and NUnit, Cedric Beust created TestNG with the idea of covering almost all types of testing models, be it functional or end-to-end. The annotations, functionalities, usability, features, and ease-of-use make TestNG a very popular choice of framework. Listed below are some of the major benefits of using TestNG-

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.

I think of a creative practice as a combination of an approach (a design philosophy) and a series of techniques (craft skills); a good tool facilitates a technique, which in turn supports an approach.

It wasn’t until I sat down to write a list of tools I can’t design without, that I realized just how many tools I rely on as an integral part of my creative process. The danger of tools is that they promote certain techniques, and that bias can alter your approach.

First and foremost a good tool does no harm, it does not dictate, or obstruct your approach. Secondly, a good tool offers flexibility in the techniques you choose. Thirdly a good tool is invisible, it leaves no marks on the end product.

If I’d written this post a year ago the list would have been different, and I hope that in a year it will be different again. These are the tools that I currently find enabling, that have contributed to my craft, and supported my approach.

Affinity Designer

I’ve always used Adobe products. Photoshop and Illustrator were the de facto graphic tools for half my life. I’ve never had an issue with the subscription licensing of Creative Cloud, which I think is proportionate for a professional set of tools. Then, around 18 months ago I got very frustrated with how sluggish Illustrator had become.

I’d written an early review of Affinity Designer, I’d been impressed at the time, so I decided to give it another try expecting the sojourn to last an hour or two before I gravitated back to Illustrator. Running the latest version of Affinity Designer was a revelation, I’ve simply never wanted to switch back.

Why not Sketch? Well, I do occasionally jump into Sketch, especially for pure vector wireframing. I was an early adopter of Sketch, but the reliability issues (long since resolved) poisoned my relationship with it. Why not Figma? Well, Figma’s real strength is in collaboration, something that I get with Sketch, and personally I find some of Figma’s features unintuitive.

Affinity Designer isn‘t perfect. I dislike the color tools, especially the gradient tool, which I find clunky. But it’s the first design app I’ve used in years that syncs closely with my creative process.

Affinity Photo

I don’t do a lot of photo manipulation, so when I switched away from Creative Cloud for design work, I was relaxed about switching from Photoshop to Affinity Photo.

In my experience, Affinity Photo is stronger than Photoshop in some areas, and weaker in others. Affinity Photo’s bitmap scaling is much better than Photoshop’s, largely due to Lanczos 3 sampling.

Affinity Photo also solves a lot of little irritations that Adobe has chosen not to address for legacy or philosophical reasons, such as the toggleable ratio setting when resizing the canvas — I’ve lost track of the hours I’ve spent in Photoshop manually calculating vertical whitespace so that it’s proportionate to the horizontal.

TinyPng

Both Affinity Photo and Photoshop are poor at web format optimizations. Photoshop perhaps has the edge, but its output certainly isn’t acceptable for production.

I run bitmaps through TinyPng, which on average halves the size of the file without any appreciable loss of quality. (It stripped 66% off the images for this post.)

Fontstand

When I started to drift away from Creative Cloud, the one service that delayed me was Adobe Fonts (née Typekit). Not so much for the webfonts — which are faster and more reliable self-hosted — but for the ability to sync desktop fonts into my design apps.

I tried Fontstand when it was first released, and I loved the concept, but was worried about the small library. When I took a second look and discovered the library is now substantial for both workhorses and experimental typefaces, it was an easy decision to switch.

Fontstand is a desktop font rental service. Once you’ve found a typeface you’re interested in, you can activate an hour-long trial, then choose to rent the font for a small fee. You can auto-renew the rental if you need to, and if you rent the font for 12 months it’s yours forever.

If there’s one tool on this list I genuinely could not design without it’s this one. Fontstand makes working with fonts from independent foundries affordable for freelancers, and it’s enriched the typographic palette available to me.

Khroma

Every designer has strengths and weaknesses. Since day one of art school, my weakness has been color. It just doesn’t come naturally to me, and I have to work quite hard at it.

An incredibly helpful tool that I’ve been using for a few months is Khroma. It helps my eyes warm up before approaching color, and helps me find a starting point that I can then refine. Comparing my design work before, and after Khroma, the latter color choices are cleaner, more vibrant, and more interesting.

Atom

A good code editor is essential, and I’ve never found one that I’m completely happy with. For years I’ve flitted back and forth between Brackets, Sublime Text, and BBEdit. I think that probably reflects the changes in the type of coding I’m doing.

For now, I’ve settled on Atom. It’s fast, reliable, and it’s not biased to front or back-end code.

CodeKit

I held out on compilers longer than I should have, using apps like Minify to minify CSS and JavaScript, and the command line to process Sass (see below). Then I found CodeKit and it’s been essential to my workflow ever since.

What I like best about CodeKit is that it’s a GUI. Which means I can change settings while coding, like toggling off the JavaScript linting, without switching mental gears into another language.

MAMP

MAMP is a tool that allows you to run a local server environment, meaning I can run PHP and MySQL without the tedious process of FTPing to a server to test a change. Mac comes with Apache, so this isn’t strictly necessary, but it’s simple to use and works well with both CodeKit and Craft (see below).

There’s a pro version of MAMP, which allows you to switch seamlessly between projects, but it’s heavily geared towards WordPress. I’m still trying to find the time to evaluate Laravel Valet.

Dash

When you first start coding you try and memorize the entire language. It’s very possible to become fluent in the core of a language, but there are always nuances, defaults, and gotchas that you miss. As you grow more experienced, you realize that all professional coders Google the answer at least once per day.

When I got tired of Googling I started using Dash which is a superb app that combines the docs of numerous different languages into a searchable window. I use it daily for everything from SVG to Twig.

LambdaTest

It doesn’t really matter what you’re building, even the indy-web needs to be tested. Ideally you’ll test on real devices, but if you can’t afford a device library — and who but the largest agencies can — you need a live testing solution.

There are a few upstarts, but your choice is basically between BrowserStack and LambdaTest. I went for LambdaTest because I prefer the style of the UI, but that’s entirely subjective. If you’re not sure, toss a coin, you’ll get the same results with both.

Sass

I can’t write CSS without Sass — and I mean that literally. If I try and write vanilla CSS I guarantee I’ll nest something with @at-root and it will throw an error.

Craft CMS

Stating any preference for a CMS online that is not WordPress inevitably invites impassioned protests from developers whose career is built on the WordPress platform. So let me say preface this by saying: if WordPress works for you, and more importantly for your clients, then more power to you; I think it’s a dog.

Shopping around for a CMS is challenging, and I’ve gone through the process several times. A good CMS needs to be in sync with your mindset, and it needs to be appropriate for your clients — all of them, because unless you’re in a large agency with multiple coders, you need to commit to a single solution in order to master it.

I have looked and looked, and finally settled on Craft CMS. Craft makes it easy to build and maintain complex, high-performance sites. It has a shallow learning curve that grows exponentially steeper, making it easy to get started with plenty of room to grow.

Vue.js

Way back when Flash went kaput I switched to jQuery, and that was a really easy route into JavaScript — ignore the people who tell you to master the core language first, do whatever it takes to start using a language, that’s how you learn. But jQuery is heavy, and I found I needed it less and less.

These days 90% of the JavaScript I write is progressive enhancements in vanilla JavaScript to keep the dependencies low. Occasionally I encounter a job that requires complex state management, and then I fall back on Vue.js. JavaScript developers are as partisan as CMS aficionados, so let’s just say I favor Vue.js because it’s not controlled by a mega-corp and leave it at that.

Ulysses

As editor at WDD, I cannot emphasize enough that the right way to write copy for the web is markdown.

Markdown is faster to write so you don’t lose the thread of your thought process, and it doesn’t impose formatting so you can easily migrate to a CMS. If you’ve ever spent 20 minutes stripping the class, id, and style tags out of a file created in Word, Pages, or (by far the worst offender) Google Docs, then you don’t need to be sold on this point.

There are a few markdown-based writing apps available, I tested half a dozen, and the one I settled on was Ulysses. I like its distraction-free mode, I love its clean exports. Everything I write, I write in Ulysses.

Screenshot Plus

Much like markdown editors, there’s no shortage of screenshot apps. My current favorite is Screenshot Plus.

Screenshot Plus has one feature that makes it standout for me, and that is its Workflows. It sounds like a small problem, but when you’re taking screenshots of a dozen sites, the extra clicks to save, switch to your editor, and open the file are laborious. I have several workflows setup in Screenshot Plus that allow me to take a screenshot, save it to a specified folder on my local machine, and then open it in Affinity Photo, all with a single click.

Spark

I get a lot of email, a lot. At one point the influx was so bad I was using multiple email apps to segment it. Yes, I use Slack daily, but it doesn’t eliminate the need for email.

I‘ve been using Spark for around six months and it’s radically sped up my workflow. I’m a big fan of the smart inbox that allows me to compartmentalize email like newsletters, and email that warrants a reply. I like that I can switch to a chronological list if I’m looking for something specific. I love the ability to pin, or snooze messages, which helps me triage my inbox.

Todoist

I’m one of those people who can’t make it through the day without being organized. I need lists and sublists, and I need something native that opens automatically when I boot my Mac, and something that sits on the home screen of my Android.

There are as many to-do apps as there are things to do. When I’m working in a team I’ll use whichever task-tracking system it prefers. But by choice I always use Todoist thanks to its balance of simplicity and power. At this point it’s something of a meta-tool, and the app I open first every morning.
