How the Typescript Required Type Works

Aggregated on: 2022-04-12 18:05:33

In TypeScript, we sometimes need to enforce that an object has required properties, even if the original type defined some of them as optional. For that, TypeScript has a utility type called Required. Let's look at how it works. TypeScript Required Utility Type By default, if we define a new type in TypeScript, all fields within that type are automatically required:

10 Books Every Senior Engineer Should Read

Aggregated on: 2022-04-12 18:05:33

Engineers are natural readers. They take enormous pleasure in learning about new things, and books are the perfect medium to cover complex ideas in depth. I picked some of my favorite books at my company, Semaphore — books that have profoundly influenced the company’s engineering culture. This list contains a mixture of classic, timeless texts and a fair share of modern game-changing publications, aimed at senior engineers and devs. But you don’t have to be a senior engineer to benefit from the books on this list, anyone interested in software development would enrich their skillset by reading them. We hope you enjoy reading this list as much as we enjoyed making it.

Digging Out Data With Adobe PDF Extract API

Aggregated on: 2022-04-12 16:35:33

There is an untold amount of scientific data in the millions of reports and scientific studies over the past few centuries. While much is digitized into easy-to-use PDF formats, the information inside may still be locked away so that it isn’t as easy as it could be to work with it in an aggregate manner. Our recently released PDF Extract API provides a powerful way to get the raw text of a document and intelligently understand the content within. This article will demonstrate how t use this API to gather and aggregate an extensive data set into a unified whole. Our Data For this hypothetical example, I imagine an astronomy organization (aptly named Department of Star Light) that examines the luminosity of stars. Before I say anything more, please note I am not an astronomer nor a scientist. Please remember this is all a hypothetical example. Anyway, the DSL (a government agency, so of course, it goes by an acronym) studies the brightness of a set of stairs. Every year, it creates a multipage report on these stars. The report contains a cover page and then twelve pages of tables representing each month of the year.

We find out ksqlDB’s role as a database on top of Kafka and what sets it apart from other databases. How do you facilitate a microservices architecture via event-processing? What does the future look like for event-streaming?

Choreo Is neither aPaaS, nor iPaaS

Aggregated on: 2022-04-12 01:35:33

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.

Building Offline-First Apps With Node.js and SQLite

Aggregated on: 2022-04-12 00:50:33

"Offline first" is an application development paradigm in which developers ensure that an app's functionality is unaffected by a temporary loss of network connectivity. Progressive web applications, which feel like native applications but run like web applications, are often built on this paradigm. This tutorial will teach you how to build an offline-first application with Node.js and a SQLite database. Let's start with an introduction to progressive web apps. Introduction to PWA Progressive Web Apps (PWAs) are web apps that use service workers, manifests, and other web-platform features and progressive enhancement to provide users with an experience comparable to native apps.

When to Use keyExtractor Prop in React Native's FlatList

Aggregated on: 2022-04-11 23:05:33

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.

How Continuous Integration Plays a Crucial Role In Business Agility

Aggregated on: 2022-04-11 19:35:32

There Was a Lot of Hype About Business Agility Unfortunately, Agility in business became one of the most hackneyed topics in IT. The main message was "Agility is Cool," and makes business flexible, reducing time to market. It's true. Why then do I raise this subject once again? Well, to show practical aspects and explain why continuous integration plays such an important role. Business Agility Meaning An Agile business is a business that is capable of reacting to a new environment and making changes quickly.

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

Aggregated on: 2022-04-11 19:35:32

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.

How Do You Do Rest Integration | Step-by-Step Methodology

Aggregated on: 2022-04-11 19:05:32

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: 2022-04-11 17:50:32

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.

Rethink Your Startup Hiring Strategy To Stand Out and Delight the Best Candidates

Aggregated on: 2022-04-11 16:05:32

Creating a Hiring Strategy Why should someone work at your company? Every company answers this question differently. Here are some valid strategies for hiring: We’ll pay the median rate in your area, but we’re investing heavily in making this the place for you to do your best work: the best work culture (early days New Relic). We’re working in a compelling technical area, which attracts a lot of talented people, so you can work with a great team and solve interesting problems. Plus we’re making a great people-focused work environment (Gremlin during my tenure there, also early days New Relic). We’re making Disneyland for engineers, with lots of perks, and top pay, in a university-like environment (early Google strategy). We’ll pay really well for you to work your ass off, and in return, you get a chance to work at a scale you won’t otherwise (Amazon today). We won’t pay you the most, but you’ll get to spend time each week working on open source software (a local software consultancy my friend ran for a while). In practice, when you haven’t done the work to articulate why someone should work there, your hiring strategy looks like this:

Application Database Monitoring: The Middle Way

Aggregated on: 2022-04-11 08:35:32

Sometimes you just need to know what a database client is doing in the database. You might be: Debugging an application and trying to figure out if its database interactions are a problem. Analyzing the performance of a serverless function to determine if some queries take too long. Testing an application and making sure its database interactions are as expected. Auditing a system to make sure it does not do anything funny in the database. Reverse-engineering an application. You get the picture, the list is endless.

POP and PUSH Testing Framework

Aggregated on: 2022-04-11 08:35:32

The POP and PUSH (P&PT) testing framework's goal is to provide a platform for combining Six Sigma testing techniques with IBM App Connect microservices. In the same way that a recording reel of film records a snapshot of test case data, the P&PT will record a snapshot of test case data. It is digital proof captured throughout the lifecycle of an App Connect Enterprise application, from development to production (application lifecycle), using Git and Jenkins' workflow. Introduction In reaction to the business scenario, the project's test case count increases. As the test case repository grows like the General Sherman Tree grows: the goal is to reduce the amount of time spent on manual testing (operations).

Digital Tech Doesn't Have to Be Toxic

The benefits of digital transformation are potentially limitless, with nearly endless ways to keep us connected with technology that optimizes efficiency, cost savings, and competitive advantage. But how do you navigate the ethical risks and unintended consequences of allowing algorithms and automation to make decisions that affect people's lives when almost two-thirds (65%) of senior executives can’t explain how specific artificial intelligence (AI) model decisions or predictions are made, and 73% struggle to get executive support for prioritizing AI ethics according to a recent study by global analytics firm FICO.

What is Data Ingestion? The Definitive Guide

Aggregated on: 2022-04-11 01:35:32

What Is Data Ingestion? Data ingestion is an essential step of any modern data stack. At its core data ingestion is the process of moving data from various data sources to an end destination where it can be stored for analytics purposes. This data can come in multiple different formats and be generated from various external sources (e.g., website data, app data, databases, SaaS tools, etc.) Why Is Data Ingestion Important? The data ingestion process is important because it moves data from point A to B. Without a data ingestion pipeline, data is locked in the source it originated in and this isn’t actionable. The easiest way to understand data ingestion is to think of it as a pipeline. In the same way that oil is transported from the well to the refinery, data is transported from the source to the analytics platform. Data ingestion is important because it gives business teams the ability to extract value from data that would otherwise be inaccessible.

Capacity and Compliance in Hybrid Cloud, Multi-Tenant Big Data Platforms

Aggregated on: 2022-04-11 01:05:32

As organizations are realizing how data-driven insights can empower their strategic decisions and increase their ROI, the focus is on building Data Lakes and Data Warehouses where all the Big Data can be safely archived. Big data can then be used to empower various data engineering, data science, business analytics, and operational analytics initiatives to benefit the business by improving operational efficiency, reducing operating costs, and making better strategic business decisions. However, the exponential growth in the data that we humans consume and generate day to day makes it necessary to have a well-structured approach toward capacity governance in the Big Data Platform. Introduction Capacity governance and scalability engineering are inter-related disciplines, as this requires a comprehensive understanding of our compute and storage capacity demands, infrastructure supply, and their inter-dynamics to develop an appropriate strategy for scalability in the big data platform. In addition to this, technical risk resolution and security compliance are equally important aspects of capacity governance.

Document Generation With Dynamic Image Generation

Aggregated on: 2022-04-10 18:20:32

One of the fascinating aspects of Adobe Document Generation is how incredibly flexible it is. One aspect of the API that can enhance the final result is the ability to include images in your template. In a typical use case, you would provide a static image defined in your data used with the API. In this blog post, I will demonstrate a more advanced example — dynamically generating images, in our case, charts, on the fly. The Basics Before we get into a more advanced demo, let’s quickly cover the basics. (My coworker has an intense look into Document Generation and images you should check out.) As our docs describe, using a dynamic image in your Word template requires a few steps.

Validate or Verify: What Should Your Tests Actually Be Doing?

Aggregated on: 2022-04-09 23:05:31

An overlooked challenge in updating your software testing strategy is simply understanding how effective existing testing is, making it hard to troubleshoot gaps or outdated practices. Understanding the distinctions between testing for validation and testing for verification can help your team build confidence and optimize software testing. Validation and Verification: A Quick Intro Developers commonly divide software testing philosophies into a couple of major areas. Yes, there are more than just two families in the taxonomy of software testing strategies, but these essential classifications offer a tried-and-true starting point.

Why Distributed Apps Need Dependency Management

Aggregated on: 2022-04-09 22:50:31

Distributed cloud applications (aka microservices) have introduced an enormous amount of complexity into the design and operation of cloud software. What used to manifest itself as complexity hidden within a single process or runtime now finds itself spread across tens or hundreds of loosely coupled services. While all of these services can use different languages and can scale independently from one another, the distributed nature can often make the app as a whole hard to navigate, hard to deploy, and hard secure. This new complexity makes it increasingly difficult to manage and contribute to cloud-native applications and beckons questions as to how we can maintain healthy cloud software. How can we take advantage of the benefits of service-oriented design without introducing friction and cost elsewhere?

What Is Dynamic Programming?

Aggregated on: 2022-04-09 22:50:31

Why Should I Care? Dynamic programming is the process of breaking down a larger problem into smaller problems. By using the answers to those smaller problems, we can find the overall solution more efficiently. We'll also learn about the term "memoization," and how it relates to dynamic programming.

The Internet of Things in Solutions Architecture

Aggregated on: 2022-04-09 22:05:31

As internet connectivity increases, an increasing number of small devices now exist with small memory and compute capacities. These sensors connect various physical entities, such as your home alarm, thermal sensors, and car. The data from millions of these connected devices needs to be collected and analyzed. For example, weather data collected from multiple sensors can be utilized to forecast weather for wind energy and farming. There are billions of connected devices in homes, factories, oil wells, hospitals, cars, and thousands of other places that are fueling digital transformation, generating huge volumes of data and growing exponentially. As IoT has become very common in the manufacturing industry for handling machine data and optimizing production, the concept of Industrial IoT (IIoT) was developed. Let’s learn more about this now.

Who Are We Helping?

Aggregated on: 2022-04-09 21:35:31

It’s hard to deny the truth that for a lot of us “difficult” means “good,” and “more difficult” is “even better.” From video games to exercise to music to cooking, if someone accomplishes something perceived as hard to do, it’s a clear indication of their skill. Conversely, saying something is easy or simple is often a veiled insult, an insinuation that anyone could do it and therefore the thing is therefore barely worth acknowledging. And, while I don’t want to discount the system upon which so much of our leisure activities are based, I think this is a lesson we in IT have taken too much to heart. I’m writing today to ask us to all consider shifting our thinking in the direction of “easy can also be good.” In fact, things which are easy are often better overall than things that require a greater level of individual virtuosity.

Know Your Gems

Aggregated on: 2022-04-08 23:50:31

In a Rails "shop" software company, it is most likely that developers and their leads do not know all the libraries (called gems in the Ruby world) their applications use. You should not be surprised when you pick a random gem from their Gemfile, ask a software engineer who has worked for 3 years in that company what that gem is used for, and you get the answer, "I don't know." I thought, I myself should not be in that precarious situation. I should know all the gems that my projects used.

10 AWS Services That Use SQL

Service Description SQL Support Use Case RDS Postgres, MySQL, etc. Full Small-medium web apps Aurora Serverless databases Full Serverless apps Redshift Data warehouse Full OLAP, Petabytes of data, analytics DynamoDB NoSQL database Some - PartiSQL Ecommerce, building fast Keyspaces Managed Cassandra (key value) Some - CQL Messaging Neptune Graph database Some - openCypher Social networks Timestream Time series database Partial IOT, Logging Quantum Ledger Cryptographically verified transactions Some - PartiSQL Finance Athena Ad-hoc queries on S3 Some - CTAS Historical data Babelfish MSFT SQL Server on Aurora Full .NET The table above shows how SQL support varies between the services. A graph database cannot be queried in the same way as a classic relational database, and various subsets of SQL, like PartiQL, have emerged to fit these models. In fact, even within standard SQL, there are many SQL dialects for different companies like Oracle and Microsoft.

Kafka Event Exchange Between Local and Azure

Aggregated on: 2022-04-08 22:50:31

While it may not be a daunting task to set up Kafka on a local machine or within a particular network and produce/consume messages, people do face challenges when they try to make it work across the network. Let’s consider a hybrid scenario where your software solution is distributed across two different platforms (say AWS and Azure or on-premise and Azure), and there is a need to route messages from Kafka cluster hosted on one platform to the one hosted on another. This could be a valid business scenario wherein you are trying to consolidate your solution with one cloud platform, and in the interim, you need to have this routing in place till you complete your migration. Even in the long term, there may be a need to maintain solution across multiple platforms for various business and technical reasons.

This article was originally published in May 2020. Coding may take years to practice to master. Having testers program a bunch of codes, fix errors in applications, and finish backlogs in weeks are challenging, time-consuming, and cost rising. The World Quality Report 2019–2020 has pointed out that lacking advanced programming expertise is one of the top challenges when applying test automation to Agile projects. We could say, the development of codeless automation testing tools is an emerging solution to the challenge.

GitOps Best Practices for DevOps Teams

Aggregated on: 2022-04-08 20:35:30

GitOps is a relatively new approach to managing production environments with the help of automation, containerization, and orchestration technologies. The idea behind GitOps is to have all the necessary infrastructure components up and running before pushing code to production. With such an automated deployment technique, every change is deployed in a predictable manner. However, not everyone has experience with this new approach – or even understands how it works. To assist you, we have compiled six actionable GitOps best practices you can use to get started in this new direction for better outcomes and more productive collaboration. The Importance of GitOps GitOps is a new way of managing and deploying software. It’s not just about Git, but the entire workflow. GitOps is a set of practices that help you deploy software that is more reliable, repeatable, and efficient. GitOps is relatively new, and it can be tough to understand how it works and how it could help your team. It basically involves Git to store all your manifest files and Kubernetes to deploy the application. Companies must look beyond DevOps to deploy their applications in a highly predictable manner. Instead of reinventing the wheel, GitOps is basically using simple tools like Git to manage your deployments.

Future JavaScript: Temporal

Aggregated on: 2022-04-08 20:05:30

I've written in the past about the many quirks of Javascript dates. The good news is that there are plans for an entirely new piece of Javascript functionality to clean up what Date() does wrong. That functionality is called Temporal. In this guide, we'll be covering why Temporal is better than Date(), and how to use it. Support for Temporal Temporal is currently a stage 3 proposal which means that although a large portion of its functionality is stable, there may be some changes in the future. As the specification is not stable yet, no browser or backend Javascript has implemented the temporal specification. If you want to try out Temporal today, you can try this polyfill (use with caution in production).

The number of people on your team can significantly impact your business. When you’re starting your business initially, it’s easy to keep track of everything that needs to be done. But as the team grows, things can get out of hand. At the same time, if multiple teams work parallel on one product, they need to communicate regularly and effectively. In most cases, people across many teams will not collaborate closely or even see each other regularly, so how can they communicate efficiently? How can they divide work between them if they don’t meet each other face-to-face?

This article was originally published in September 2021. Serverless has been one of the hottest trends for many years now and it’s easy to see why. If I could try to encapsulate a huge topic in one nugget, serverless lets developers focus on code and not infrastructure. Of course, there are a heck of a lot of caveats to that statement, but in general, it’s incredibly freeing as a developer to be able to focus on features and not servers.

The Many Quirks of JavaScript Dates

Aggregated on: 2022-04-08 18:05:30

JavaScript dates are weird. Famously, Brendan Eich wrote the first version of JavaScript in 10 days - and the Date function itself was no exception. It is based on code that was ultimately deprecated in Java. That means JavaScript has inherited a Date function which was found to be buggy and problematic in Java, leaving it full of issues. You may have even encountered some problems yourself. You may be wondering, then, "what's so weird about it?". Let's look at all the quirks and common pitfalls with JavaScript's Date constructor so that you can avoid them.

We'll do this without a back-end, and then iteratively add the optional — but selectively valuable — back-end (sample Node.js). The word "liberating" in the title of this tutorial is somewhat overloaded, on purpose:
