How the TypeScript Extract Type Works

Aggregated on: Thu Apr 14 2022 20:05:34 GMT+0000 (Coordinated Universal Time)

The Extract utility type lets us check a union type for specific members, and returns a new type based on what is leftover. It's quite similar in format to the Exclude type. Let's find out how it works.

Message Queuing and the Database: Solving the Dual Write Problem

Aggregated on: Thu Apr 14 2022 19:35:34 GMT+0000 (Coordinated Universal Time)

Developing a modern application means developing for the cloud, with uptime, scalability, geographic distribution, and low latency at the forefront of concerns. This has led to the widespread adoption of application architectures based on event-driven microservices. Breaking the elements of an application down into microservices allows us to (for example) scale different services independently. It is simply the most efficient way to architect applications for the cloud. However, embracing event-driven microservices also presents some challenges. With so many different services in motion at the same time, communication between them can become a challenge.

What Can Go Wrong While Following Agile Methodology

Aggregated on: Thu Apr 14 2022 19:35:34 GMT+0000 (Coordinated Universal Time)

Introduction Most of the Job Postings you will see will have the term Agile Process mentioned somewhere in their Job Description. If you talk to Developers or Managers in your network, most of them will tell you that their teams are using Agile Methodology. So I believe it is fair to say that the term Agile Process is trending nowadays in Software Industry, and using Agile Process in your team is as cool as using AI/ML in your code. Agree?

Using the PDF Embed API With Vue.js

Aggregated on: Thu Apr 14 2022 15:20:34 GMT+0000 (Coordinated Universal Time)

I've recently become acquainted with Adobe's PDF Embed API. As you can probably guess by the name, it's a library for embedded PDFs on a web page. It is not just a simple viewer; it has APIs for interacting with the PDF and excellent mobile support. This is a part of the Document Cloud service that provides other PDF tools (extraction, conversion, and so forth). I've been playing with the viewer a bit and wanted to see what Vue.js integration would look like. Here's my solution, but note that I'm still learning about the product, so it could probably be done better. First off, to use the API, you need a key. Clicking the link from the webpage will walk you through generating a key. One important note on this, though. You have to lock down your key to a domain, and that domain cannot be changed either. Also, you can only specify one domain. So, if you want your domain and localhost, create two projects, generate two keys, and set them as environment variables for your development and production environment. I did my testing on CodePen and had to use this domain: cdpn.io

From Zookeeper to Raft: HA and Fault-Tolerance

Aggregated on: Thu Apr 14 2022 01:20:34 GMT+0000 (Coordinated Universal Time)

Introduction Alluxio implements a virtual distributed file system that allows accessing independent large data stores with compute engines like Hadoop or Spark through a single interface. Within an Alluxio cluster, the Alluxio master is responsible for coordinating and keeping access to the underlying data stores or filesystems (UFS for short) consistent. The master contains a global snapshot of filesystem metadata, and when a client wants to read or modify a file, it first contacts the master. Given its central role in the system, the master must be fault-tolerant, highly available, strongly consistent, and fast. This blog will discuss the evolution of the Alluxio master from a complex multi-component system using Zookeeper to a simpler and more efficient one using Raft. The operation of a file system can be thought of as a sequence of commands performed on the system (e.g., create/delete/read/write). Executing these commands one at a time in a single thread gives us a sequential specification for our file system that is easy to reason about and to implement applications on top of. While this sequential specification is simple, the actual implementation of Alluxio’s virtual distributed file system consists of many moving parts all executing concurrently: the master who coordinates the system, the workers who store the file data and act as a cache between the client and the UFS, the UFSs themselves, and the clients who, at the direction of the master, access all other parts of the system. Again here, we may want to reason about each of these individual components as a sequential thread executing one operation at a time, but in reality, they are running complex systems themselves.

Go Application Vulnerability Cheatsheet

Aggregated on: Thu Apr 14 2022 01:20:34 GMT+0000 (Coordinated Universal Time)

Securing applications is not the easiest thing to do. An application has many components: server-side logic, client-side logic, data storage, data transportation, API, and more. With all these components to secure, building a secure application can seem really daunting. Thankfully, most real-life vulnerabilities share the same root causes. And by studying these common vulnerability types, why they happen, and how to spot them, you can learn to prevent them and secure your application.

SingleStore DB Loves R

Aggregated on: Thu Apr 14 2022 00:50:34 GMT+0000 (Coordinated Universal Time)

Abstract The R programming language is very popular with many Data Scientists. At the time of writing this article, R ranks as the 11th most popular programming language according to TIOBE. R provides many compelling data manipulation capabilities enabling the slicing and dicing of data with ease. Often data are read into and written out of R programs using files. However, R can also work with database systems. In this article, we'll see two quick examples of how Data Scientists can use R from Spark with SingleStore DB.

Making Your Own Email Subscription Service with Node.JS

Verification and Validation in Testing

Aggregated on: Wed Apr 13 2022 20:20:33 GMT+0000 (Coordinated Universal Time)

Introduction You are at the right place! This is not a free vocabulary-building class but a critical evaluation of a much sought-after debate around verification and validation in the software testing world. Why do we need to know the difference between Verification and Validation? Even though they sound just about the same, they carry different meanings depending on what you intend to do as a tester/developer in the software development and testing process. They both go hand in hand while solving a problem. However, there is a lot of confusion around the meaning of these two words concerning software testing. While there may be many definitions of these terms in various fields on the internet, here we will look at these terms in the testing space and analyze both of these terms in detail. Verification vs Validation Software testing is a vast field. It involves various methods and processes proposed to solve different software testing issues. Verification and Validation are also a part of the same group in software testing. It is also known as a V-Model (Verification and Validation model) in the context of software development and testing.

Saving Form Data in Client-side Storage

Aggregated on: Wed Apr 13 2022 19:50:33 GMT+0000 (Coordinated Universal Time)

Today's post is one of those that started off with me worrying that it was going to be too simple and quickly turned into a bit of a complex little beast. I love that as it usually means my expectations were wrong and I've got a chance to expand my knowledge a bit. This post came from a simple idea: While working on a form, can we save your form data for restoring later in case you navigate away, close the tab by accident, or perhaps get "surprised" by an operating system update. While this is not something you would want to use in every situation (for example, storing a new password field), there are plenty of examples where this could be helpful, especially in a larger form. For our demo, I will only cover client-side storage, which means the data will be unique to one browser on the device. Although what I described here could be tied to a back-end service for storing temporary form data as well.

Don’t Have a DevOps Team? This Is Why You’re Wrong

Aggregated on: Wed Apr 13 2022 19:20:33 GMT+0000 (Coordinated Universal Time)

If you’re not sure what “DevOps” means and whether or not you need a DevOps team in your organization, this article is for you. Here, I provide an overview of DevOps and its various facets, discuss why you most probably want a dedicated DevOps team in your company, and cover those edge cases where you might not need one. What Is “DevOps”? “DevOps” is a workplace culture that merges “development” and “operations.” Before the DevOps methodology was established, engineers worked in silos, focusing solely on their particular area of expertise and usually unwilling to learn about other fields. DevOps eliminates silos by ensuring collaboration between developers and operations engineers throughout the software development lifecycle (SDLC). Teams can thus deliver optimized products much faster.

Benefits of Setting Initial and Maximum Memory Size to the Same Value

Aggregated on: Wed Apr 13 2022 17:05:33 GMT+0000 (Coordinated Universal Time)

When we launch applications, we specify the initial memory size and maximum memory size. For the applications that run on JVM (Java Virtual Machine), initial and maximum memory size is specified through "-Xms" and "-Xmx" arguments. If Java applications are running on containers, it’s specified through "-XX: InitialRAMPercentage" and "-XX: MaxRAMPercentage" arguments. Most enterprises set the initial memory size to a lower value than the maximum memory size. As opposed to this commonly accepted practice, setting the initial memory size the same as the maximum memory size has certain "cool" advantages. Let’s discuss them in this post. 1. Availability Suppose you are launching your application with the initial heap size to be 2GB and the maximum heap size to be 24GB. This means when the application starts, the operating system will allocate 2GB of memory to your application. From that point, as the application starts to process new requests, additional memory will be allocated until a maximum of 24GB is reached.

Understanding Cross Browser Testing and Responsive Testing

Aggregated on: Tue Apr 12 2022 20:50:33 GMT+0000 (Coordinated Universal Time)

Introduction The Internet is inevitable in the current time. It is everywhere, and the entire world depends on it to function, perform day-to-day activities and stay connected with people from different corners. Gone are the days when testers only chose to create websites for selected browsers and hardly faced issues maintaining a website on a few browsers. As the technology matured, many significant players entered the browser market. Even the users evolved, became tech-savvy, and improved their browsing habits. Now was a time when businesses were in critical need of cross-browser testing and responsive testing to stay ahead of the competition. Cross-browser testing focuses on the website's overall functionality; responsive web testing verifies the look and feel of the web application. Cross-browser testing deals with the analysis of the web browsers that their users use, and responsive testing deals with the devices where the company's user base visits the websites. Let us shed some light and understand cross-browser and responsive testing in detail. What Is Cross Browser Testing? We all know that testing cross-browser compatibility of websites "is of utmost importance. It helps understand how stable your web application is across various technologies, browsers, operating systems, and devices. The adoption of cross-browser testing is to provide a better user experience irrespective of which browser-OS-device combination your users use to access your website. In cross-browser testing, the testers generally validate the web application's functionality and ensure its user-friendliness and performance are up to the mark across the web browsers. Businesses can also take the help of cloud-based automated cross-browser testing tools to have access to a wide range of real devices to test their web and mobile applications. Different browser engines render websites differently; even the version of each browser causes the code uniquely. It means the code behind the websites is read differently by every browser. So, various cross-browser testing strategies are critical for website accessibility. It is how different browsers render a web page:

Not Just Buckets: Are You Aware of ALL Your Public Resources?

Aggregated on: Tue Apr 12 2022 19:05:33 GMT+0000 (Coordinated Universal Time)

Public exposure to resources is a point of dread for many security practitioners. Public resources are low-hanging fruit for attackers seeking to access sensitive information or manipulate an activity -- or even deny the availability of mission-critical resources. One well-known culprit for exposing resources is AWS built-in mechanisms. While misconfiguring them is a common and legitimate concern for security practitioners charged with protecting AWS environments, we often see another mechanism that may be even more misconfiguration-prone: resource-based policies.

Background WSO2 has been building enterprise software since 2005 and the team has been working with 1000s of enterprise customers ever since. WSO2’s products cover a range of capabilities from API Management (APIM), Integration, Stream Processing, and Customer Identity and Access Management (CIAM). All these product capabilities are available to the users as installable software (binaries) that can be installed on customers' choice of infrastructures such as physical servers, virtual machines, and cloud infrastructure. In addition to these installable versions, WSO2 has offered these functionalities as a cloud (SaaS) solution via WSO2 Cloud. This SaaS offering was a scalable installation of WSO2 products on a shared cloud infrastructure which did not provide many capabilities beyond the installable components’ functionality. WSO2 team has identified this as a limitation of the platform given the fact that most enterprises are moving towards cloud and cloud-native solutions. After several years of RnD efforts, the WSO2 team is thrilled to announce the General Availability (GA) of Choreo on 30th March 2022. The official announcement can be found here.

When to Use keyExtractor Prop in React Native's FlatList

Aggregated on: Mon Apr 11 2022 23:05:33 GMT+0000 (Coordinated Universal Time)

In React Native, the FlatList component works well to render a long list of data. It renders only the items shown on the screen in a scrolling list and not all the data items at once. To render a scrollable list of items using FlatList, you need to pass the required data prop to the component. The data prop accepts an array of items. Each item in the array represents a single item in the list. Another required prop is renderItem, which takes an item from the data and renders it on the list. This prop accepts a function that returns the JSX to be rendered.

Creating Your Own Schema With the Adobe Document Generation Word Add-in

Aggregated on: Mon Apr 11 2022 19:35:32 GMT+0000 (Coordinated Universal Time)

When Document Generation API launched a few months ago, we included a Microsoft Word add-in to make it simpler for folks to design their Word templates for use within the API. To use the add-in, you needed to provide data in JSON format, either pasted in or uploaded via an existing file: This worked perfectly fine if you had your data ready to go, but that wouldn’t always be possible, especially if you’re starting a new project and need to start prototyping quickly. Luckily, our latest update adds a few features to simplify this. Let’s take a quick look at what’s changed. Note — for folks who’ve already installed the Word add-in, it should update automatically for you. Suppose you haven’t installed this add-in yet; head over to our documentation for instructions on how to do it.

When you need two or more applications and services to exchange data between them on a regular basis, REST integration (or REST API integration) is one method that slowly but steadily gains the status as the new and preferred standard. But as with any other project where you need to connect apps and web services via API, integrating REST requires good preparation and a solid methodology to avoid project delays, development overhead, and too many errors. So, how do you do REST integration the right way? Well, in this article, we explore exactly this topic, offering you a step-by-step guide of all the things you need to consider and clarify before you even start working on the code.

Using SingleStore DB to Map Crimes and Visualize Hot Routes

Aggregated on: Mon Apr 11 2022 17:50:32 GMT+0000 (Coordinated Universal Time)

Abstract Many great visualization techniques, such as kernel density mapping, can help us map and analyze crime concentrations. However, sometimes, it may be more beneficial to visualize crime concentrations along a linear network, such as a bus route or subway/underground line. Law enforcement agencies could use this to target resources at particular hot spots. To map these hot spots, we can use hot routes. Hot routes enable crimes to be mapped along sections of a linear network using thematic mapping (colour and line width). An excellent tutorial illustrates hot routes, using R, for the Bakerloo Line on the London Underground. Using Python, we'll use the example described in that tutorial and apply it to SingleStore DB. In a previous article, we have already seen one approach to model and store the London Underground network in SingleStore DB.
