The Benefits of Implementing Serverless Architecture in Your CI/CD Pipeline

Aggregated on: Thu Apr 27 2023 04:45:22 GMT+0000 (Coordinated Universal Time)

Serverless architecture has been gaining momentum in the past few years as a popular way of building and deploying applications. It eliminates the need for developers to manage and maintain servers, allowing them to focus on writing code and delivering features. In this article, we will discuss the benefits of implementing serverless architecture in your CI/CD pipeline. CI/CD, or Continuous Integration/Continuous Deployment, is a practice that allows developers to deliver changes to their code frequently and reliably. It automates the process of building, testing, and deploying code changes to production. By implementing serverless architecture in your CI/CD pipeline, you can reap a number of benefits.

DALL-E and the Future of Art

Aggregated on: Thu Apr 27 2023 04:15:22 GMT+0000 (Coordinated Universal Time)

As we have seen in our previous article, artificial intelligence (AI) is transforming many aspects of our lives, including the world of art. With the help of machine learning algorithms and generative models (i.e., a machine “learns” a piece of information and uses it to generate a new image), AI can now create works of art that are often indistinguishable from those created by human artists. AI-generated images are a type of art that is generated through algorithms that analyze patterns and styles in existing art and use this information to create new and original pieces. AI-generated art can take many forms, including paintings, sculptures, music, and even fashion.

Does the OCP Exam Still Make Sense?

Aggregated on: Wed Apr 26 2023 21:15:22 GMT+0000 (Coordinated Universal Time)

Much has been written about the impact of AI tooling on software development, or indeed on any creative endeavor. Some of those blogs may already be written by AI, who knows? If the benefits for mundane coding tasks today are any foretaste of what lies ahead, I dare not contemplate what the next year will bring, let alone the next decade. I’m not overly worried. The price of job security was always continuous upgrading of your skillset - which is why I’m studying for the Oracle Certified Professional Java SE 17 developer exam. The OCP is reassuringly and infuriatingly old-school. It grills you on arrays, shorts, ObjectOutputStream, the flip bit operator ^, and much you’re probably not going to write or encounter. What is the point? I’ll tell you. On the one hand, the programming profession has changed beyond recognition from when I started in 1999 and long before that. I look forward to veteran Jim Highsmith’s upcoming book Wild West to Agile. It’s supposed to be liberally sprinkled with personal anecdotes from the era of punch cards and overnight compiles. The teasers remind me of the classic Four Yorkshiremen sketch by Monty Python, boasting how tough they had it. “We lived eighteen to a room! – Luxury! We lived in a septic tank.”

The Equivalence Rationale of Neural Networks and Decision Trees: Towards Improving the Explainability and Transparency of Neural Networks

Aggregated on: Tue Apr 25 2023 23:00:21 GMT+0000 (Coordinated Universal Time)

Over the past decade, neural networks have succeeded immensely in various industries. However, the black-box nature of their predictions has prevented their broader and more reliable adoption in fields such as health and security. This has led researchers to investigate ways to explain neural network decisions. One approach to explaining neural network decisions is through saliency maps, which highlight areas of the input that a neural network uses most while making a prediction. However, these methods often produce noisy results that do not clearly understand the decisions made.

SmartStoreNET: Malicious Message Leading To E-Commerce Takeover

Aggregated on: Tue Apr 25 2023 22:30:21 GMT+0000 (Coordinated Universal Time)

SmartStoreNET is the leading open-source e-commerce platform for .NET, which makes it suitable for companies running Windows Server. Next to the operation of an online business, it offers advanced features, such as CRM tools, a blog, and a forum. As a result, a SmartStoreNET instance handles highly sensitive data such as credit card, financial, and personally identifiable information that have to be protected from attackers. During recent security research, my team and I discovered two vulnerabilities that could allow attackers to gain control of the server where SmartStoreNET is installed by sending one malicious message to the instance's administrator. In this article, I present the root cause analysis of two Cross-Site Scripting bugs and then describe how they could be exploited by attackers. Finally, I will describe the patches applied by the maintainers and the limitations of those patches.

Feature Interaction Metrics

Aggregated on: Tue Apr 25 2023 21:45:21 GMT+0000 (Coordinated Universal Time)

In software development, feature interaction occurs when the behavior of a software system is affected by the combination of features or inputs. Feature interaction can cause unexpected and undesirable behavior in software systems, which can be challenging to detect and resolve. Feature interaction matrices are one of the techniques used to identify and analyze feature interaction in software systems. These metrics can help identify potential problems caused by feature interactions and guide software developers in designing better systems. What Is a Feature Interaction Matrix? A feature interaction matrix is a table that lists all possible combinations of features in a software system and identifies any interactions between them. Each row and column in the matrix represents a feature, and the cells represent the interactions between the features. The matrix is populated by testing the software system with different combinations of features to identify any interactions that may cause unexpected behavior.

Smart wearables are incredibly useful when it comes to outdoor workouts, especially in situations where you don't want to be carrying your mobile phone. A smartwatch that tracks your real-time exercise records and routes monitors your health status, and even supports maps and real-time navigation is practically a must-have tool for outdoor sports enthusiasts nowadays. However, not every smartwatch supports independent, real-time navigation on the watch. Fortunately, for watches without such a feature, it is still possible to use offline maps to navigate. Fitness apps can take advantage of offline maps to provide users with navigation features on smartwatches. The problem is, how can the offline maps generated on a fitness app be synced to a smartwatch?

Building a RESTful API With Java Spring Boot

Aggregated on: Tue Apr 25 2023 18:45:21 GMT+0000 (Coordinated Universal Time)

Spring Boot is a popular framework for creating powerful RESTful APIs, and in this tutorial, we will use it to develop a simple API that simulates a credit score rating. The API endpoint we will create will allow a user to retrieve a credit score rating by sending a request to the API. However, it is important to note that we will not be linking up to any actual backend systems to pull a real credit score. Instead, we will use a random number generator to generate the score and return it to the user. Although this API is relatively simple, it will demonstrate the basics of REST API development using Java and Spring Boot. This tutorial will provide a hands-on introduction to building RESTful APIs with Java Spring Boot. Prerequisites Before we start, we must ensure that a couple of prerequisites are completed. To follow along and run this tutorial, you will need the following:

A popular and practical use case for web3 is generating tickets to live events. Blockchains such as Ethereum can guarantee the ownership, originator, and authenticity of a digital item, effectively solving the problem of counterfeit tickets. While major players such as Ticketmaster struggle to mitigate scalpers (trying desperately to control who can resell tickets, where, and for how much) and ticket fraud—web3 already has a solution. The ticketing industry is ripe for disruption. In this tutorial, we’ll look at how to create such a ticketing solution using ConsenSys Truffle, Infura, and the Infura API. We’ll deploy a smart contract that acts as a ticketing service and creates tickets as ERC-20/ERC-721 digital tokens. We’ll also walk through a few architectures of potential frontends that could interface with the contract, and together function as an integrated, full-stack, web3 ticketing system.

A Critical Detail About Kafka Partitioners

Aggregated on: Tue Apr 25 2023 15:30:21 GMT+0000 (Coordinated Universal Time)

Apache Kafka is the de facto standard for event streaming today. Part of what makes Kafka so successful is its ability to handle tremendous volumes of data, with a throughput of millions of records per second, not unheard of in production environments. One part of Kafka's design that makes this possible is partitioning. Kafka uses partitions to spread the load of data across brokers in a cluster, and it's also the unit of parallelism; more partitions mean higher throughput. Since Kafka works with key-value pairs, getting records with the same key on the same partition is essential.

How To Place Text and Shapes on an Image in Java

Aggregated on: Mon Apr 24 2023 22:45:21 GMT+0000 (Coordinated Universal Time)

Coding new visual elements into an image file begins with a basic understanding of how image files are normally displayed. When an image file is loaded for display on any of our devices, software from that device must first decode the file and store the result of that decoding in a temporary block of memory called a buffer. Buffers become responsible for communicating the color information stored by each individual pixel within an image (in each instance, the file is opened), and from there, that color information can be rendered by our device’s lighting (usually LCD or LED) display. When we want to layer new text or shapes which display on top of an image, we need to access the file in memory and create our own temporary image buffer to work within. This new buffer will give us control over an entirely new layer of pixels in our image, allowing us to temporarily influence — and eventually save changes to — our image’s final display. How our image subsequently implements our new buffer depends on the original file format. If we begin with a PNG file, for example, we’ll leverage built-in transparency features to layer new content on top of the original file. If we begin with a JPG file, which doesn’t offer transparency features, we’ll end up with a single, blended image layer that effectively mixed the new and original content together. In either case, the result of the operation will retain the encoding of the original file, allowing us to easily write our resulting (slightly larger sized) file encoding to a new file entirely.

Is self-management an essential building block on an organization’s path to business agility or a nice-to-have cultural twist to, for example, keep teams happy and attract new talent? While many people, particularly at the management level, are skeptical about the concept, I am convinced that organizations need to descale and regroup around aligned, autonomous, self-managing teams in a complex environment. Ultimately, only the people closest to the customers’ problems can solve those within the given constraints while contributing to an organization’s sustainability.

And of the most popular cloud providers, Amazon Web Services (AWS) is the most widely used. While AWS offers many solutions for storing application parameters, understanding which option best fits your application and use case can be difficult. In this article, we’ll dive into the best ways to store your application parameters in AWS. Overview of Application Properties Storage Let us take the example of AWS Lambda — a popular compute service that allows developers to run code without provisioning or managing servers. When writing code for Lambda functions, it's common to use configuration properties to define how the function should operate. Configuration properties can include things like environment variables, database connection strings, and other settings that are specific to your application.

Remote Testing Mobile Devices and Embedded Platforms Using Squish

Aggregated on: Mon Apr 24 2023 19:45:21 GMT+0000 (Coordinated Universal Time)

Automation testing tools rely on object identification based on object models or object properties such as name, type, and position. We have many automation tools for web and desktop applications. While testing mobile devices, hardware, and electronic equipment poses unique challenges, which can be sorted out with remote system access. Where the local and remote system is not geographically co-located, interactive script recording and debugging can become cumbersome and time-consuming. Existing remote desktop solutions bring problems of their own: interoperability of the controlled and controlling platform, compatibility of the test framework and remote control application, setup and configuration issues, and others. Accessing specific embedded or mobile devices may not be possible. Squish is a cross-platform testing tool that supports many desktop, mobile, and embedded platforms. In addition, Squish allows automation of the testing of graphical user interfaces (GUI) for applications written in various programming languages, including Java, .NET, and Qt.

API Gateway Pattern: Features and the AWS Implementation

Aggregated on: Mon Apr 24 2023 19:15:21 GMT+0000 (Coordinated Universal Time)

API Gateway is an architectural pattern to create a façade that exposes the internal system’s data to external clients in a decoupled layer, reducing the dependency between frontend and backend components. Nowadays, that pattern is widely spread in the computing field being used in business applications and integration solutions for small, medium, and large enterprises. The value of breaking the dependency between clients and backend implementations is very substantial. Many paramount functions of modern distributed systems can be implemented in the API gateway. The list of functions is quite large and will be elucidated in the next sections of this article. Currently, we see API gateways usage in critical mission applications and use cases such as microservices architecture, legacy monoliths, monolith migration to microservices projects, and integration layers. Additionally, the API gateways are involved in different deployment models, since the bare-metal servers running on-premises, virtual machines like Amazon EC2, and containerized solutions such as Kubernetes on Amazon EKS, even in the modern serverless computing platform, covering all possible deployment spectrum available today. The issues solved using the API Gateway pattern are explored in section 2.

10 Best Practices for Using Kubernetes Network Policies

Make E2e Testing Easier With the Right Tools

Aggregated on: Mon Apr 24 2023 15:30:21 GMT+0000 (Coordinated Universal Time)

End-to-end (e2e further in the text) testing is immensely important since there are issues that can only be discovered while testing the system as a whole, testing it from one end to another. That also adds a greater level of complexity to e2e tests, making them longer, slower to execute, and with more points of potential failure compared to lower-level tests with a smaller scope, especially when compared to tiny and blazing-fast unit tests. Since e2e tests bring a lot of value, we don’t want to neglect them. We also want to make our lives easier when doing e2e testing, which we can do with the right tools. Apart from automating our e2e tests, we can speed up our e2e tests if when they are not automated. Let us dig deeper into what exactly we can do to make e2e testing easier and faster to execute.
