One of the crucial factors in ensuring the website’s best performance is to test every aspect of the website and improve it over time. The most commonly used testing technique is A/B testing which is simple to conduct and optimize your website to get traction Conversion is considered an essential factor in deciding the success of your business. Whether a small-scale or large-scale business, attracting visitors and converting them into leads is always necessary. If you know how to improve your chances of success, why not go for it. A/B testing helps the business quickly achieve its goals within time to achieve that success.

Did You Know the Fastest Way of Serializing a Java Field Is Not Serializing It at All?

Aggregated on: 2022-01-20 09:49:41

Learn how to apply C++'s trivially copyable scheme in Java and get blazing serialization speed using Unsafe and memcpy to directly copy the fields in one single sweep to memory or to a memory-mapped file. In a previous article about open-source Chronicle Queue, there was some benchmarking and method profiling indicating that the speed of serialization had a significant impact on execution performance. After all, this is only to be expected as Chronicle Queue (and other persisted queue libraries) must convert Java objects located on the heap to binary data which is subsequently stored in files. Even for the most internally efficient libraries, this inevitable serialization procedure will largely dictate performance.

Get Out Early With Perl Statement Modifiers

Aggregated on: 2022-01-20 02:04:41

When I first started writing Perl in my early 20’s, I tended to follow a lot of the structured programming conventions I had learned in school through Pascal, especially the notion that every function has a single point of exit. For example: Perl sub double_even_number { # not using signatures, this is mid-1990's code my $number = shift; if (not $number % 2) { $number *= 2; } return $number; } This could get pretty convoluted, especially if I was doing something like validating multiple arguments. And at the time I didn’t yet grok how to handle exceptions with eval and die, so I’d end up with code like:

Microservices: Good for Developers' Mental Health

Aggregated on: 2022-01-20 01:34:41

Let’s face it: developers’ work and responsibilities have increased dramatically in the last 15 years. We develop, run and maintain critical services used by millions of users around the globe 24/7, 365 days a year, and a single service disruption may cause severe business disruption. Remember the last time Gmail went down? Yeah, that. And as apps and APIs change even more frequently, we developers can feel overwhelmed, and can experience anxiety, burnout, stress and fatigue. The COVID new reality hasn't helped. So when I heard that we needed to transition our monolithic app to a microservices design, I feared that it meant that we would have even shorter deadlines to meet – with code that we had even less time to test. I did not look forward to breaking the news to my development team. Already, I could hear groans about the mountain of tech debt we would create in order to release a candidate by the deadline. Would it be resilient? Maintainable? Reliable? Observable. Sort of. This is a startup's way of saying, "Yes."

For some reason, this query, which was running fine until today, now takes a long time.

Leetcode: Improving String Performance in Swift

Aggregated on: 2022-01-20 01:04:41

Problems with strings are one of the most common problems with Leetcode. By solving a task on Leetcode, you can also compare your solution with other solutions in terms of performance and memory usage. I have experience solving issues with strings, and my task execution time is often better than 100% of other users' solutions. Let's see how we can speed up solving a difficulty with strings. Strings in Swift In many programming languages, a string is an array of characters with direct access to the elements of the string/array. In this case, you can access a substring or character instantly in O(1) time. However, Swift is built differently. Let's take a more in-depth look at what lies behind the facade.

Which Special Characters Must Be Escaped in Regular Expressions?

Aggregated on: 2022-01-20 00:04:41

In most regular expression engines (PCRE, JavaScript, Python, Go, and Java), these special characters must be escaped outside of character classes: [ * + ? { . ( ) ^ $ | \ If you want to find one of these metacharacters literally, please add \ before it. For example, to find the text $100, use \$100. If you want to find the backslash itself, double it: \\.

How LambdaTest Cuts E2E Test Speeds

Aggregated on: 2022-01-19 20:19:41

One of the most fundamental concepts in software testing is the so-called "testing pyramid". This mental framework helps inform software engineers of which types of tests they need. As you go up the pyramid, the tests become more expensive to run, so you should have fewer of them. Unit tests are fast and cheap to write and run, so you can have many of them. End-to-end tests are expensive, so you should only have a few of them for your most critical user paths.

Requirements for Running K8ssandra for Development

Aggregated on: 2022-01-19 15:49:41

K8ssandra is a complete stack for running Apache Cassandra® in production. As such, it comes with several components that can consume a lot of resources and make it challenging to run on a dev laptop. Let’s explore how we can configure K8ssandra for this environment and run some simple benchmarks to determine what performance we can expect. Managing Expectations The K8ssandra Quickstart is an excellent guide for doing a full installation of K8ssandra on a dev laptop and trying out the various components of the K8ssandra stack. While this is a great way to get your first hands-on experience with K8ssandra, let’s state the obvious: running K8ssandra locally on a dev laptop is not aimed at performance. In this blog post, we will start Apache Cassandra® locally then explain how to run benchmarks to help evaluate what level of performance (especially throughput) you can expect from a dev laptop deployment.

What Is a Kubernetes Operator?

Aggregated on: 2022-01-19 15:19:41

Kubernetes is popular due to its capability to deploy new apps at a faster pace. Thanks to "Infrastructure as data" (specifically, YAML), today you can express all your Kubernetes resources such as Pods, Deployments, Services, Volumes, etc., in a YAML file. These default objects make it much easier for DevOps and SRE engineers to fully express their workloads without the need to learn how to write code in a programming language like Python, Java, or Ruby. Kubernetes is designed for automation. Out of the box, you get lots of built-in automation from the core of Kubernetes. It can speed up your development process by making easy, automated deployments, updates (rolling update), and by managing your apps and services with almost zero downtime. However, Kubernetes can’t automate the process natively for stateful applications. For example, say you have a stateful workload, such as a database application, running on several nodes. If a majority of nodes go down, you’ll need to reload the database from a specific snapshot following specific steps. Using existing default objects, types, and controllers in Kubernetes, this would be impossible to achieve.

The Universal Language: Reliability for Non-Engineering Teams

Aggregated on: 2022-01-19 12:49:41

We talk about reliability a lot from the context of software engineering. We ask questions about service availability, or how important it is for specific users. But when organizations face outages, it becomes immediately obvious that the reliability of an online service or application is something that impacts the entire business with significant costs. A mindset of putting reliability first is a business imperative that all teams should share. But what does reliability mean for people outside of engineering? And how does it translate into best practices for other teams? In this blog post, we’ll investigate:

Open-Source SPL That Can Execute SQL Without RDB

Aggregated on: 2022-01-19 10:04:41

SQL syntax is close to natural language, with a low learning threshold and the bonus of first-mover advantage, it soon became popular between database manufacturers and users. After years of development, SQL has become the most widely used and most mature structured data computing language. However, SQL must work based on RDB, and there is no RDB in many scenarios, such as encountering CSV \ restful JSON \ MongoDB and other data sources or performing mixed calculations between these data sources, such as CSV and XLS. In these scenarios, many people will choose to hard code algorithms in high-level languages such as Java or C#, etc., which requires writing lengthy underlying functions from scratch, and the execution efficiency is difficult to guarantee.

Leveraging Gamification in your Mobile App for Superior User Experience: Top Tips

Aggregated on: 2022-01-19 09:49:41

In general, video games are considered to be dopamine-releasing products. When you're happy or excited, the chemical is released into your system. To make a non-gaming app more enticing to users, you must provide them with a cause to return and compete with one another regularly. Therefore, it is safe to assume that incorporating this experience into any of your applications makes them more joyful for your customers to use. Having to rewrite your website or app is the least appealing aspect of this solution. The addition of gamification to your program does nothing to improve its performance; rather, it just enriches the user experience by making it more entertaining and rewarding for the user. The inclusion of gamification elements directly influences the number of downloads of an app.

Aggregated on: 2022-01-18 20:34:40

In this blog, you will learn how to use AWS Lambda versions and aliases by means of a Java example. You will create a simple AWS Java Lambda, create several versions for it and you will learn how to use aliases for your environments. Enjoy! 1. Introduction AWS Lambda allows you to run serverless functions onto the AWS environment. More general information about AWS Lambda can be found at the Amazon website. An important item when working with lambdas, is how to keep control over the different versions of your lambda and over which version runs onto which environment. You can imagine that you have a production environment which runs version 1 of your lambda, a test environment which runs version 2 and a development environment which runs version 3. Version 1 is your stable version, version 2 is the one with extra functionality or fixed bugs and is about to make the step to production but needs to be verified by the customer first, version 3 is your development version and is not yet tested and therefore the most instable version. In this post, you will learn how to manage your versions in these different environments. You will create a sample Java lambda and will create several versions of it.

WSO2 API-M 3.2.0: Creation of a New KeyStore With a New Self-Signed Certificate and CN

Aggregated on: 2022-01-18 16:34:40

This article describes the steps to create a new KeyStore with a new self-signed SSL certificate and a new CN (Common Name) in WSO2 API-M 3.2.0 and how it can be used to invoke APIs’ in WSO2 from a remote host. By default, WSO2 API-M has a KeyStore named wso2carbon.jks which contains a self-signed certificate. However, the default certificate has Common Name (CN) as localhost and this certificate can be used to invoke the APIs from the same server where WSO2 API-M is hosted. This article is useful when the client/end-user wants to invoke APIs exposed via WSO2 gateway that is hosted on a remote server and using an SSL certificate. Steps: 1. Open a command prompt and go to <API-M_HOME>/repository/resources/security/. Then, create the new KeyStore that includes the private key by executing the following command. We will provide the hostname/domain name where WSO2 API-M is hosted as the CN value while creating this new KeyStore. For example, in this case, it is api.test.wso2.com.

DevOps: CI/CD Tools to Watch Out for in 2022

Aggregated on: 2022-01-18 09:04:40

From the evolution of successful software-powered companies, the following five building characteristics have emerged: Speed, Agility, Automation, Security, and Quality. All five of these can be developed with DevOps Principles and new technologies. But with so many DevOps technologies on the market, software development has become more complicated than ever. CI/CD approach help reduce complexity while helping you deploy your software smoothly. CI/CD is about continually packaging, testing, and efficiently deploying code into a production environment. This approach has the advantage of eliminating integration issues and mitigating risk in deployments by making them frequent. Breakdown of CI/CD Continuous Integration is a technique where developers connect and share their work as they progress on tasks. In the process, they continuously make changes to the entire system instead of making them one by one. The result is a reduction in bugs and a higher quality product. One of the main benefits of using Continuous Integration is sharing code across teams. When teams can see what other teams are doing, they can collaborate more efficiently. Again, this leads to higher quality products and fewer or no bugs. Lastly, Continuous Integration increases the speed at which developers push code changes by reducing the chance for conflict or error. It's like an assembly line, where all members of the team pitch in and assemble a car in parallel, rather than one person working on one part of the car at a time. Continuous Delivery is a similar technique and includes delivering software after every successful build. Teams that practice Continuous Delivery will usually automate their release process. This eliminates errors that can occur when human intervention is required. In addition, by practicing Continuous Delivery, teams can update their software more often without worrying about any errors getting through. You can also use this technique for events or seasons when customers are less active to lower your risk for downtime in production environments. Continuous Deployment is the final step where the teams, if they want to, should be able to deploy to production at any given moment. This process can be completely automated, and DevOps aims at zero-touch automation of deployment. Still, sometimes that may not be practically easy, and hence we rarely see companies employing Continuous Deployment. While Continuous Deployment may not be practical across all departments or products, it has helped some companies improve their development process significantly by decreasing the time spent on bug fixes and speeding up the release cycle by deploying software frequently.

Optimization Techniques Using Java Streams

Aggregated on: 2022-01-18 00:49:40

The incredible amounts of data collected by digital technologies have created an explosion of big data analysis. It allows companies, governments, and other organizations to find patterns and predict future behavior. For example, it can aid in sale projections, marketing campaigns, solving and preventing crime, etc. The possibilities are disparate and limitless. Similarly, AI applications and neural networks in particular use big datasets. When working on a complex problem modeled by a neural network it is very important to collect big amounts of data that is properly formatted and labeled. We divide this data into training and testing datasets that we use to get the values of the weight matrices of the model.

Backend Engineering Skills Are Emphasized Too Heavily for Principal Engineers

Aggregated on: 2022-01-17 17:34:40

There is a bias toward backend engineers at the principal engineer level. This leaves frontend engineers heavily disadvantaged when it comes to promotion time. When someone says they’re a fullstack engineer, what they usually mean is one of two things: 1) They’re a coding bootcamp grad that has minimal experience with Node.js and an emphasis on the frontend. Or, 2) they’re an experienced backend engineer that knows a little bit of HTML and CSS. A truly fullstack software engineer is a rare find.

One of the main goals is to create a stable and high-quality code profile from aggregated and anonymous data as quickly as possible (to maximize the number of users that can benefit from this) while ensuring that we have enough data to optimize accurate performance applications. To design a scalable Android application in a multi-core device environment, an Android developer must be able to create concurrent execution lines that mix and match data from many resources. Mobile teams tend to focus on external monitoring, how the app behaves on the device, evaluating whether code is running correctly, resources are being managed efficiently, screens are displaying correctly, user commands are being logged, and so on. All of this is important, but it's just the tip of the mobile monitoring iceberg. Effective mobile monitoring requires full end-to-end and end-to-end visibility into everything that affects the app experience with the user, not just what happens on the device itself. Front-end monitoring tools might not show them what's going on, or the mobility team might be a separate organization from the rest of the IT team.
