Progressive Web App Development: How to Cook PWA in 2022 – DEV Community

When talking about web development, Progressive Web Apps have been a buzzword for a while. But will your company benefit from going down the PWA road? Read how and when you should use and should NOT use this technology now and in 2022. Introduction to PWA Progressive Web Apps (PWAs) are a fairly recent trend in web and mobile app development. Coined by Google engineer Alex Russell in 2015, the term refers to web applications that use “progressive” design approaches in order to behave and function similarly to native apps. What that specifically means may not be perfectly clear, as there is no precise definition of what does or does not make a progressive web app. However, there are some defining characteristics that are indicative of PWA design patterns. These include the use of ServiceWorkers (background scripts that run in the browser in order to provide features like push notifications) and app manifests (standardized JSON files that instruct the platform how to install and manage your app). There are also several common design themes that are often pointed to as being unique to PWA. Benefits and Drawbacks of PWA Employing progressive web app technology in an application’s development has many benefits, though there are also some drawbacks to consider. The main benefit of PWA design is that it is mostly platform-independent. This means that an app can be developed using a single codebase and deployed on several different platforms. Simplifying the development in this way reduces the time and resources necessary to get an app to market. Platform independence combined with the fact that PWAs are inherently installable makes...

Why My Model with 90% Accuracy Doesn’t Work | by Meagvo | Dec, 2021 | Towards Data Science

Why My Model with 90% Accuracy Doesn’t Work Model Performance Metrics for Imbalanced Datasets When you’re dealing with marketing problems like customer churn (when a customer stops using a company’s product over a certain period of time) prediction, the raw dataset is often imbalanced, meaning that the classes are inherently not balanced. Basically, what this means is the percentage of your customers who churn might be a lot lower than those who don’t. In this example, the binary classification problem might have an 80–20 split, with only 20% of customers discontinuing their engagement with the company and 80% continuing to make a purchase. The problem is, that 20% could be VERY important to the business’s bottom line. Think about it — a gifting company has 100,000 customers with an average value of $50 per person. that’s $5,000,000 from those customers, but if 20% stop buying from the company, you’re losing $1,000,000! Over the course of a few years, that can add up for even the largest of ecommerce companies or brick and mortar shops. Therefore, a major goal for the company’s marketing department is to predict when a customer will churn and implement some sort of intervention to prevent that from happening. Machine Learning for Churn Prediction Now if your company has a good data science/data analytics team, you could be in luck. With a good customer churn prediction model, you can intervene before a customer abandons your business and potentially get them to return to their loyal status. Now, we get to the next problem — when we’re working with binary classification models, the imbalanced classes tend to...

Native Mobile App Development or React Native vs Flutter vs Cordova: What to Choose in 2021

Native Mobile App Development or React Native vs Flutter vs Cordova: What to Choose in 2021

Native mobile app development: Android vs iOS The first time I faced an issue of choosing between Android or iOS app development was in 2012. Two of my friends from the biomedical engineering department were about to build an app for senior people providing real-time messaging with their doctor. Yet, they couldn’t prove to each other which operating system was better: both certainly had a point.  There are several things to consider if you need to pick a native platform, including: According to data from August 2021, the worldwide market share of Android devices is 72.73%, while for iOS gadgets it’s just 26.42%. However, the general picture is not enough for making a definite decision, and should not discredit iOS. Platforms‘ popularity differs for each particular region, e.g. in the USA iOS market share is substantially higher than the one of Android. At the same time if, let’s say, you develop an app for Ukrainians, you can not count too much solely on iOS. Despite the difference between them, both operating systems constantly improve and create excellent user experience. Here is a closer comparison of iOS and Android that highlights their peculiarities. Things to consider Swift, Objective-C Tools for app development Android SDK supported on all platforms Xcode+iOS SDK supported only on macOS Ease of app development and testing With a broad variety of android devices you need to take into account their peculiarities and a rather wide range of screen sizes. This also makes testing more complicated. Relatively small number of devices and screen sizes for which you develop the app. Testing is rather straightforward. Quite flexible material...
