Must-Have Tool for Anonymous Virtual Livestreams

Aggregated on: 2023-04-12 17:15:14

Influencers have become increasingly important as more and more consumers choose to purchase items online — whether on Amazon, Taobao, or one of the many other prominent e-commerce platforms. Brands and merchants have spent a lot of money finding influencers to promote their products through live streams and consumer interactions, and many purchases are made on the recommendation of a trusted influencer. However, employing a public-facing influencer can be costly and risky. Many brands and merchants have opted instead to host live streams with their own virtual characters. This gives them more freedom to showcase their products and widens the pool of potential on-camera talent. For consumers, virtual characters can add fun and whimsy to the shopping experience.

If you're developing applications for a business, then one of your most important tasks is collecting payment for goods or services. Sure, providing those goods or services is essential to keeping customers happy. But if you don’t collect payments, your business won’t be around for very long. In the dev world, when we talk about infrastructure, we often consider the resiliency of our servers and APIs. We don’t talk about payment processing in the same way. But we should.

Relearning Java Thread Primitives

Aggregated on: 2023-04-12 17:15:14

I’ve coded in Java since the first beta. Even back then, threads were at the top of my list of favorite features. Java was the first language to introduce thread support in the language itself. It was a controversial decision back then. In the past decade, every language raced to include async/await, and even Java had some third-party support for that… But Java zigged instead of zagging and introduced the far superior virtual threads (project Loom). This post isn’t about that. I think it’s wonderful and proves the core power of Java. Not just as a language but as a culture. A culture of deliberating changes instead of rushing into the fashionable trend.

The Importance of Test-Driven Development in Software Development

Aggregated on: 2023-04-12 14:30:14

Software development has come a long way since the early days of programming. The importance of developing high-quality software has become increasingly important as businesses rely more heavily on technology to drive their operations. One method that has gained traction in recent years is Test-Driven Development (TDD). In this article, we'll explore what TDD is, why it's important, and how to implement it in your software development process. What Is Test-Driven Development? Test-Driven Development is a software development technique that emphasizes writing automated tests before writing the actual code. The process starts with writing a test case, then writing the code that satisfies that test case. Once the code has been written, the test is run to ensure that it passes. If the test fails, the code is revised until the test passes. This process is repeated until all the tests have passed and the software is considered complete.

How To Find Broken Links Using Cypress [With Examples]

Aggregated on: 2023-04-11 18:00:14

Have you ever experienced a 404 error? From an end user’s perspective, a 404 error (or broken link) experience can be a complete turn-off. Apart from annoying end-user experience, broken links (or dead links) on a website can dampen the SEO (Search Engine Optimization) activity. The more 404 pages you have on your site, the fewer time users spend on the site. To reduce the bounce rate and build a top-notch online reputation for your website, it is essential to check for broken links using Cypress. It is relatively easy to check broken links on the website by performing Cypress testing compared to other test automation frameworks like Selenium.

Amazon S3 is the most commonly used managed storage solution in AWS. It provides object storage in a highly scalable and secure way. AWS guarantees 11 9s for its durability. Objects stored in S3 are shared access objects; shared meaning they can be accessed by different clients at the same time. S3 provides low latency for data, and it has high throughput (able to move data in and out of S3 quickly). S3 is highly available, durable, and can encrypt data. S3 provides access management, lifecycle management, and the ability to query-in-place (no need to move to a data lake). Static website hosting is another very popular feature of S3.

Lessons Learned From Picking a Java Driver for Amazon ElastiCache for Redis - Part 2

Aggregated on: 2023-04-11 16:45:14

In part one of this series, we looked at Jedis as the Java-based Redis driver when used in combination with ElastiCache for Redis in clustered mode. We learned that during a failover, Jedis takes some time to figure out what the new primary is before it can restore the connection to the ElastiCache cluster. In this post, I’ll share some of the lessons learned from switching to Lettuce as the driver for our Java-based application. A Different Driver Lettuce, a Java-based driver for Redis, is the default driver for Redis when working with Spring Framework. Lettuce is a fully non-blocking Redis client built with Netty providing Reactive, Asynchronous, and Synchronous Data Access.

Rolling Numbers Animation Using Only CALayers

Aggregated on: 2023-04-11 16:45:14

I’m an iOS Engineer at Triumph Labs, where I develop TriumphSDK for game devs. Not so long ago, I got a task to completely reimplement UI and animations. One of the most interesting parts was implementing of balance view with rolling animation of the number in it. At the first sight, it looks pretty simple, but we needed a well-configured custom solution. Of course, I checked existing libraries that I could reuse and adjust this kind of animation for our needs. After the first try, I figured out that the libraries are not so adjustable, and we cannot control the animation of each number. I won’t go into details too much. However, I decided to make my own solution from scratch.

Handling Bad Messages via DLQ by Configuring JDBC Kafka Sink Connector

Aggregated on: 2023-04-11 16:15:14

Any trustworthy data streaming pipeline needs to be able to identify and handle faults. Exceptionally while IoT devices ingest endlessly critical data/events into permanent persistence storage like RDBMS for future analysis via multi-node Apache Kafka cluster. (Please click here to read how to set up a multi-node Apache Kafka Cluster). There could be scenarios where IoT devices might send fault/bad events due to various reasons at the source points, and henceforth appropriate actions can be executed to correct it further. The Apache Kafka architecture does not include any filtering and error handling mechanism within the broker so that maximum performance/scale can be yielded. Instead, it is included in Kafka Connect, which is an integration framework of Apache Kafka. As a default behavior, if a problem arises as a result of consuming an invalid message, the Kafka Connect task terminates, and the same applies to JDBC Sink Connector. Kafka Connect has been classified into two categories, namely Source (to ingest data from various data generation sources and transport to the topic) and Sink (to consume data/messages from the topic and send them eventually to various destinations). Without implementing a strict filtering mechanism or exception handling, we can ingest/publishes messages inclusive of wrong formatted to the Kafka topic because the Kafka topic accepts all messages or records as byte arrays in key-value pairs. But by default, the Kafka Connect task stops if an error occurs because of consuming an invalid message, and on top of that JDBC sink connector additionally won’t work if there is an ambiguity in the message schema.

What Are Microservices Architecture and How Do They Work?

Aggregated on: 2023-04-11 16:15:14

In the era of mobile computing, app developers should be able to deploy actions quickly and make changes without redeploying the entire app. As a result, it has led to a new way of building software called "microservices." Microservices are small, self-contained parts of an app that each do their job and talk to each other through APIs. Even though these microservices are different, they work together to complete the job. Microservices are becoming an essential part of modern app architecture, so let's talk about what microservices architecture is, how they work, and why they are helpful.

Streaming in Mule 4: Processing Large Data Sets

Aggregated on: 2023-04-11 15:15:14

Mule is a lightweight enterprise service bus and integration framework provided by MuleSoft. The platform is Java-based and hence makes use of the JVM for process execution. It is the fundamental task in MuleSoft to integrate different systems, and there are scenarios where we take data from one system, then process it, and finally load it into another system (ETL), where these source and end systems can be Database, Salesforce, SFTP/FTP or Files. There can be various approaches we can adopt to achieve the above goal. But when processing a reasonable amount of data, one of the concerns designers and developers need to address is the potential of retrieving an enormous number of results in a single load session because if the size of the data being loaded into the JVM Heap Memory exceeds its size, we get the memory out of bound exception, ourapplication crashes, and the process execution fails. Some Conventional Solutions To address the problem we encountered in the above scenario, we can make use of the following logic:

What Is a Streaming Database?

Aggregated on: 2023-04-10 15:15:14

A streaming database is a type of database that is designed specifically to process large amounts of real-time streaming data. Unlike traditional databases, which store data in batches before processing, a streaming database processes data as soon as it is generated, allowing for real-time insights and analysis. Unlike traditional stream processing engines that do not persist data, a streaming database can store data and respond to user data access requests. Streaming databases are ideal for latency-critical applications such as real-time analytics, fraud detection, network monitoring, and the Internet of Things (IoT) and can simplify the technology stack. Brief History The concept of a streaming database was first introduced in academia in 2002. A group of researchers from Brown, Brandeis, and MIT pointed out the demand for managing data streams inside databases and built the first streaming database, Aurora. A few years later, the technology was adopted by large enterprises. The top three database vendors, Oracle, IBM, and Microsoft, consecutively launched their stream processing solutions known as Oracle CQL, IBM System S, and Microsoft SQLServer StreamInsight. Instead of developing a streaming database from scratch, these vendors have directly integrated stream processing functionality into their existing databases.

Container Security: Top 5 Best Practices for DevOps Engineers

Aggregated on: 2023-04-10 14:45:14

Containerization has resulted in many businesses and organizations developing and deploying applications differently. A recent report by Gartner indicated that by 2022, more than 75% of global organizations would be running containerized applications in production, up from less than 30% in 2020. However, while containers come with many benefits, they certainly remain a source of cyberattack exposure if not appropriately secured. Previously, cybersecurity meant safeguarding a single "perimeter." By introducing new layers of complexity, containers have rendered this concept outdated. Containerized environments have many more abstraction levels, which necessitates using specific tools to interpret, monitor, and protect these new applications.

Single Cloud vs. Multi-Cloud: 7 Key Differences

Aggregated on: 2023-04-09 01:00:13

The advent of the Internet has brought revolutionary changes in the IT world. One of the notable changes is that virtualization has advanced with the Internet to become an integral part of the IT infrastructure of modern organizations. As a result, companies are now relying on the virtual online entity housing data and services, commonly referred to as the cloud. The switch to the cloud was brought on by the exponential data growth in the last couple of decades. In fact, studies predict that by 2025, the cloud will be storing up to 100 zettabytes of data. What Is the Cloud? The cloud refers to a global network of remote servers, each with a unique function that are connected and work together as a unitary ecosystem. In simple terms, the cloud describes what we commonly know as the “internet.” This remote network of servers is designed to either store and manage data, run applications, or deliver content or a service such as streaming videos or accessing social media networks for anyone with an internet connection.

What Will Come After Agile?

Aggregated on: 2023-04-09 01:00:13

I think that probably most development teams describe themselves as being “agile” and probably most development teams have standups, and meetings called retrospectives. There is also a lot of discussion about “agile,” much written about “agile,” and there are many presentations about “agile.” A question that is often asked is, what comes after “agile?” Many testers work in “agile” teams, so this question matters to us. Before we can consider what comes after agile, we need to consider what agile is — an iterative, incremental development methodology. Agile teams develop software in iterations and each iteration makes an increment toward the team’s goal. An agile team can decide, after an iteration or two, that the goal they are working towards should be changed and start to work on a new goal. Working iteratively makes the team agile as it can change direction quickly and easily. There are several agile methodologies and one of the most widely used methodologies is scrum.

Boldness in Refactoring

Aggregated on: 2023-04-07 17:45:13

The old engineering adage “Don’t touch it, it works” is terrible. Don’t listen to it. It might be OK at a small scale, but as time goes by, the bit rot spreads through your code and servers polluting everything. Large swaths of your system become “no-man's-land.” As you’re developing a new system, you must always “touch it” and make sure we hire engineers who aren’t afraid to do so. Yes, I get it. I said that sentence frequently in the past. I understand the motivation. Management doesn’t care about the bit rot in our future. They care about the here and now. Why are you wasting time on this feature?
