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 (...)

Twenty-five years after its creation, Java is still the most popular programming language according to the latest TIOBE index. Who would have thought that the language invented by Sun would have such a destiny when it was created in 1995?Today, knowing how to program in Java language has become almost indispensable. Why? 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 (...)

More and more companies and teams are switching towards the serverless architecture for their applications.In this article, I will be explaining serverless and we will be deploying our first hello world lambda function!What is Serverless?Serverless simply means that you don’t have to manage the servers on which your application runs.You don’t have to take care of patching the system, installing antivirus software or configuring firewalls. Also, you don’t have to worry about scaling your application as the load increases, it is handled automatically!Hence, it allows you to focus more on the functionality of your application.Why is it better?Normally, when you are creating a dynamic web application you (...)

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 (...)

How #redux Middlewares can be helpful for you

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 (...)
How To Set Up a Network Bridge for LXD Containers

Most of our web applications run in LXD containers. Not without reason LXD is one of the most important features of #ubuntu Server for me. There are many ways to access a web application in an LXD container from outside. For example, you can use a reverse proxy to control access to the containers. Another possibility is to set up a network bridge so that the containers are in the same network as the container host (the Ubuntu server).

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 (...)

Let’s time travel a bit. Imagine you’re a developer back in the mid-2000s. You’re working on building a web application, and you are solving for the desktop Internet browser because it’s the only platform available. It’s easier to keep your server and client codebase integrated and let the framework abstract away the client-server communication.Fast forward a few years — browsers have now matured to support HTML5 and JavaScript, permitting richer client-side capabilities. At this point in time, the front-end developer emerged. Although developers began to diverge in their roles and responsibilities to keep up with evolving technological advancements, monolithic frameworks such as PHP, Ruby-on-Rails, and ASP.NET continued to dominate the developer ecosphere thanks to their simplicity, (...)

IntroductionAll web applications display dynamic information that is fetched from the computer resources that support the web application (in contrast to web sites, which may only display static content). In many cases a web application is supported by a web server like Tomcat or by “serverless” components like Amazon Web Services (AWS) Lambda. To simplify the discussion in this article, the back end system will be referred to as a web server.When the web application page is displayed, it will contain the dynamic information fetched from the web server. There are two ways that dynamic information from the server can be included in the web page:JavaScript running on the client (the web browser) can fetch the data from the server and insert the data into the page by modifying the in-memory (...)
