Is the end coming for the Apple App Store and Google Play Store? The title is obviously an exaggeration, but in all seriousness, the time has come for a new wave of #mobile technology to come to the fore. In 2018, Twitter announced that it has started offering its mobile PWA as its main site. PWA? What’s that?Progressive Web Apps (PWA) is the future of mobile apps and the web, pushed by heavyweights in the industry especially Google. With features such as adding to home screen, offline support, push notifications and more, a PWA offers a user experience approaching that of a native mobile app.Here’s how a PWA works. Imagine you have a Customer Relationship Management (CRM) app that is also PWA compliant. You just need to visit the app using a normal URL in your mobile browser. If you have (...)

Photo by Samuel Zeller on UnsplashAbout Performance TestingPerformance testing is a method of identifying whether software (a web application) is capable to handle a high load, among other possible performance issues. Therefore, the ultimate goal of a performance test is to analyze the overall performance against heavy loads. Apache JMeter is an open-source tool that can be used exactly for this purpose.What is a Single-node Server?This is the case when a server runs on a single machine only. If the server crashes due to some issue, there will be a downtime until the issue is fixed.What is a Two-node Cluster?A two-node cluster is a setup where two servers are configured with high availability. If clustering is used, there won’t be downtime due to a server crash. The advantage of having (...)

Wallets are gateways to cryptocurrencies and, as the #blockchain space has grown, the variety of wallets available has also grown. Most people who want to dabble with a small amount of crypto, start off their crypto journey by setting up hot wallets in the form of phone, desktop, or web application. Hot wallets focus primarily on convenience and are great for making coin transfers on the go.While hot wallets may be convenient, they force users to sacrifice #security and the underlying basis of crypto: having complete control of one’s wealth. Thus, as people get a stronger grasp of blockchain technology and understand how to improve security of their Crypto assets, they either opt for hardware wallets, or even brain wallets.User Experience is ImportantGiven that wallets are gateways to (...)

Simply because the language that now belongs to Oracle allows you to do everything. It is thus possible to create desktop applications, Web applications or mobile applications via Android, which is crushing the smartphone market. The question of the need to learn Java does not therefore arise in 2019.Books to learn Java are numerous and it is therefore very difficult to find your way around such an important choice.

Photo by Stephane LacasaDemystifying an industry in motion for users and developers alike.Last year I decided to dive into crypto headfirst.The space was as boisterous as a teenager — acne & all — and growing up just as fast. I was intrigued. And I was wary.I’d been working on web applications since the dot-com era, and wanted a new challenge. Taking the lead on the technical vision of a stablecoin — a cryptocurrency pegged to real world asset — seemed like a good way to dive in headfirst. ?Most of what I saw in the space were inflated egos of self-proclaimed “visionaries” and dollar signs behind every perked-up ear. Everyone I met was pitching their brand new infrastructure/platform, and it was exhausting. To top it off, the jargon thrown around at events was so thick you could cut it with a (...)

The Displaced Universal #react Web App in a #serverless FutureTaco Lost in the AbyssIt’s easy to get lost in the labyrinth of choices when building a web app these days. I jumped on the “universal” bandwagon (back when it was called “isomorphic”) early and have many learned lessons since.A universal app is one that can execute the same code universally — on the server and client. React provides ways to render components to static markup as documented in the official docs, typically used on a Node server. This support revolutionized the way many of us think of and write JavaScript. The practicality of scaling and maintaining such a mechanism however is questionable.Universal… Why?Beyond the ability to share code across the stack, why go universal? Some would say SEO (just that one word). I remember (...)

Executive Summary (TLDR)Asynchronous #javascript in the form of Single Page Applications (SPA) offer an incredible opportunity for improving the user experience of your web applications. CSS frameworks like Bootstrap enable developers to quickly contribute styling as they’re working on the structure and behaviour of things.Unfortunately, SPA and CSS frameworks tend to result in relatively complex solutions where traditionally separated concerns - HTML-structure, CSS-style, and JS-behaviour - are blended together as a matter of course — Counter to the lessons learned by previous generations.CC BY-SA 401(K) 2012This blending of concerns can prevent entry level developers and valued specialists (Eg. visual design, accessibility, search engine optimization, and internationalization) from making (...)

Scale Your #react Web Application with Redux MiddlewaresWhen it comes to state management in React, Redux is quite popular and does the required job efficiently. Though dispatching actions and updating the store with reducers works great with simple Web Applications, Redux provides a powerful functionality of middlewares which makes your life easy in building a large scale web application.It provides a third-party extension point between dispatching an action, and the moment it reaches the reducer.As the documentation suggests, Redux middlewares work in a similar manner as express middlewares do ( if you come from server-side ). Someway between Action Creators and Reducer, the Middleware intercepts the action object before Reducer receives it and gives the functionality to perform (...)

Software Composability in Crypto
▻https://hackernoon.com/software-composability-in-crypto-a705700c3816?source=rss----3a8144eabfe3
One of the most interesting breakthroughs in crypto is the strong degree of composability the technology lends to software development. Composability is the ability to combine various components of a software stack in different ways. To keep things simple, we’ll split the stack into two parts: front-end and back-end. Applications on the web today, including the likes of Twitter, Amazon, Facebook, both develop and own their proprietary software stack. The primary factors driving the proprietary stacks of today are twofold: closed data structures and monopolistic business models. More user data increases a company’s monetisation potential through strategies such as targeted advertisement and induces strong user lock-ins. As such, web applications are incentivized to monopolize the user (...)
