Virtual Machine Gaming: Setup and Performance Boost

Aggregated on: Wed May 24 2023 17:15:39 GMT+0000 (Coordinated Universal Time)

Virtualization creates many opportunities to optimize the use of hardware resources. That works not only for organizations that build high-performance servers to run complex environments. Individuals can also benefit from the functions and features that workload virtualization provides. But what if you want to use a virtual machine for gaming? In short: that’s possible. A gamer can use a virtual machine (VM) to run games with reasonable benefits over traditional PC gaming approaches. Virtual machines were designed to make hardware usage more convenient and flexible along with the boost in security. However, when you consider VM gaming, things become more complicated. The performance issue arises especially urgently when you want to run a resource-intensive game on a virtual machine.

What Is Cross-Site Scripting? Cross-Site Scripting (XSS) is a code-injection vulnerability that occurs in applications that process HTML when developers do not sanitize user input well enough before inserting it into an HTML template. It allows an attacker to insert arbitrary JavaScript code into a template and execute it in the user’s context: In the image above, the developer failed to sanitize the content of the "last-name" div, which resulted in users being able to include malicious scripts by manipulating their last name.

Aggregated on: Wed May 24 2023 16:00:39 GMT+0000 (Coordinated Universal Time)

React Router is a widely used routing library for React applications due to its API, which simplifies integration. The latest version of React-router (v6) was released in November 2021 and marked a significant API change. Version 5 of React-router was released in March 2019, but it faced some problems with its routing algorithm and configuration defaults. In version 6, React hooks are the driving force behind the new release, resulting in more efficient and compact code. The article discusses the major problems with version 5, as well as changes to routing logic, bundle size reduction, route protection, and redirection, new features for forms in version 6.4, and also the features that are no longer available in the new version.

What Is End-To-End Testing? E2E Testing Tutorial With Examples and Best Practices

Aggregated on: Wed May 24 2023 15:45:39 GMT+0000 (Coordinated Universal Time)

End-to-end testing, or E2E testing, as the name suggests, is the testing methodology that validates a software workflow from start to end. The primary goal of E2E testing is to simulate an end user's application journey and ensure that all integrated components, dependencies, and other integrated pieces work as expected. While this looks obvious that the testing has to be done with all components attached, end-to-end testing is the last stage of testing and is usually done infrequently. This is especially so if the application under test is extensive, i.e., it has hundreds of components and thousands of dependencies.

Extending Java APIs: Add Missing Features Without the Hassle

Aggregated on: Wed May 24 2023 15:30:39 GMT+0000 (Coordinated Universal Time)

The Java API is vast. That’s great, but sometimes a missing method or capability can be frustrating. With Manifold, developers can solve this problem without having to wait for Java to add a feature in a later version. Even more importantly, Manifold provides many such extensions out of the box, making Java better for developers. In this post, we will discuss the extension capability. It lets us change classes in the Java API in a compatible way without risk. If Java adds these APIs later, then we can seamlessly switch to them. Before I proceed, the code for this tutorial and the previous tutorials in the series is available here. I will skip setting up as it was covered in the previous installments of the series. You can see the specific pom file settings for this time in the project directly.

How To Become a 10x Dev: An Essential Guide

Aggregated on: Wed May 24 2023 15:30:39 GMT+0000 (Coordinated Universal Time)

In a Nutshell Software development is a team sport. Your individual performance doesn't matter as much as the performance of your whole team and company. By improving how you work, you only ADD to your team's performance. By improving how everyone works, you MULTIPLY your team's performance. Multiplying the whole team's performance will put you on a much faster lane for being noticed and promoted than being a crazy efficient individual contributor. Boosting other people's performance requires a different mindset and approach than boosting your individual performance. In this article, I'll show you 16 proven ways to multiply your team's performance (or even the whole company). The Common Misconception of 10x Dev If you google the term "10x developer", you'll get many results related to individual performance. Check out the quotes from a few of the top results that I've got:

8 Data Anonymization Techniques to Safeguard User PII Data

Aggregated on: Tue May 23 2023 22:45:38 GMT+0000 (Coordinated Universal Time)

In today's data-driven market, data translates to more power and opportunity for businesses. But as it is said, “With great power comes greater responsibility.” As more personal information is being collected and analyzed by organizations, the need to protect an individual's privacy and prevent the misuse or unauthorized access of the personal data comes with it. The Netflix Prize, a dataset released in 2006 to improve and innovate Netflix's recommendation algorithm, containing a large amount of user data from Netflix's movie recommendation service, including user ratings and rental histories, spurred the need for data anonymization. According to the DLA Piper’s latest annual General Data Protection Regulation (GDPR) Fines and Data Breach Survey, Europe have issued a total of EUR1.64bn (USD1.74bn/GBP1.43bn) in fines since 28 January 2022 under GDPR. A year-over-year increase in aggregate reported GDPR fines of 50%.

Redefining DevOps: The Transformative Power of Containerization

Aggregated on: Tue May 23 2023 17:30:38 GMT+0000 (Coordinated Universal Time)

In the rapidly evolving digital age, DevOps has emerged as a crucial paradigm reshaping the software development landscape. DevOps, a term derived from 'Development' and 'Operations,' integrates these two historically siloed functions into a unified approach focused on shortening the software development life cycle. As a result, DevOps practices promote faster, more reliable software releases and facilitate continuous integration, continuous delivery, and high availability, enhancing business competitiveness and agility. However, the ceaseless quest for increased efficiency and more robust delivery processes has led us to an innovation that is having a profound impact on the way we develop and deliver software: containerization. Containerization involves encapsulating or packaging up software code and all its dependencies to run uniformly and consistently on any infrastructure. This remarkable technology is not merely an incremental improvement in the DevOps world; it is a significant leap forward, transforming the operational effectiveness of software development and deployment.

MongoDB: 5 Syntactic Weirdnesses to Keep in Mind

Aggregated on: Tue May 23 2023 11:30:38 GMT+0000 (Coordinated Universal Time)

People like to complain about MongoDB. For instance, maybe they feel that it ruined their social network, or any number of other less recent complaints. The debate gets so heated, though, that sometimes valid criticisms - and nothing is above criticism - are dismissed as bandwagon hatred. It's a problem that Slava Kim seems very aware of in this recent blog post on some of the syntactic weirdnesses of MongoDB. It's not bashing, Kim stresses. For developers to effectively use any technology, they need to understand the "sharp edges." Kim goes into detail for each warning, covering five general areas:

Monetizing Mods: What we Learned from Valve and 'Skyrim'

Aggregated on: Tue May 23 2023 11:30:38 GMT+0000 (Coordinated Universal Time)

There’s an old adage, “the best things in life aren’t free.” However, in the gaming community, this notion is completely upended. Mods are incredibly prevalent in the gaming world, and usually come at no cost. These normally free downloads change the original and unaltered, or vanilla, game in various capacities. Mods can present minor tweaks, like “Half-Life 2: Update,” or major overhauls such as “Half-Life 2: Cinematic Mod.” Whether a mod manifests as simply improved eye candy, or an entirely different experience, there’s usually one constant: it’s free. Well, aside from the cost of the base game. However, the modding dynamic was poised for upheaval when the always-innovative Valve added a paid mods feature to its signature Steam Workshop recently. An early paid mod for “Skyrim,” a fishing mod, was removed quickly because it apparently employed assets from another mod. This coupled with an internet outrage prompted Valve to nix the idea entirely.

This third post in this series of blogs about MaxScale is finally getting where you want to go: Install and configure MaxScale. The first blog in this series was an overview of what MaxScale is and the second about how to set up a Cluster of MariaDB servers, using MariaDB Replication, for MaxScale to access. But now it's time to introduce MaxScale. If you skipped the second post as you already know how to set up MariaDB with Replication and all that, be remineded that I will use the same Linux server setup as outlined there even for the MaxScale server and for a client to do some testing, and I recommend you stick with that for now (for MariaDB itself you can use any relevant setup you want, MaxSCale doesn't really care, but MaxScale is pretty new and has still not been tested on that many platforms, so try to stick to the CentOS 6.5 setup I propose.

MapReduce Algorithms: Understanding Data Joins, Part II

Aggregated on: Tue May 23 2023 11:00:38 GMT+0000 (Coordinated Universal Time)

It’s been awhile since I last posted, and like last time I took a big break, I was taking some classes on Coursera. This time it was Functional Programming Principals in Scala and Principles of Reactive Programming. I found both of them to be great courses and would recommend taking either one if you have the time. In this post we resume our series on implementing the algorithms found in Data-Intensive Text Processing with MapReduce, this time covering map-side joins. As we can guess from the name, map-side joins join data exclusively during the mapping phase and completely skip the reducing phase. In the last post on data joins we covered reduce side joins. Reduce-side joins are easy to implement, but have the drawback that all data is sent across the network to the reducers. Map-side joins offer substantial gains in performance since we are avoiding the cost of sending data across the network. However, unlike reduce-side joins, map-side joins require very specific criteria be met. Today we will discuss the requirements for map-side joins and how we can implement them. Map-Side Join Conditions To take advantage of map-side joins our data must meet one of following criteria:

My last article raised an interesting discussion whether you should see tests more as documentation or more as specification. I agree that they can contribute to both of them, but I still think tests are just - tests... There were also complaints about my statement that testing often becomes tedious work which nobody likes. Also here I agree, that techniques like TDD can help you to structure your code and make sure you code exactly what is needed by writing the tests, but the result of the process will still be a class which needs to be tested somehow.

Making A Good Thing Even Better: Google Open Source WindowBuilder and CodePro Profiler

Back in September, when Google announced they were to make the Instantiations tool suite free for all, I thought things couldn't get better than this for Java developers. Well I was wrong, today Google trumped that announcement with their latest plan to open source both WindowBuilder and CodePro Profiler. Google is donating the source and the IP for both of these former products to the open source community through the Eclipse Foundation, and creating two new Eclipse projects. All in all, this is a value of more than $5 million dollars worth of code and IP. For those unfamiliar with the products, WindowBuilder provides the best available Java GUI Designer available, integrated into Eclipse allowing you to build Swing, SWT, RCP and GWT interfaces. CodePro Profiler helps you to identify performance issues in your Java code.

The approach aimed to get the same functionality as you would get by using the jar file in a regular JAVA setting, but as I demonstrated, Equinox does have the benefit of allowing multiple JXSE instances to run simultaneously, which is a great benefit when developing JXSE applications. In this second tutorial, we will cover some ways of improving the functionality by severing the dependency on the 4.2x version of Jetty (which has just released it's 9.0 version!) and we will introduce some basic tools to visualize the properties and functions of JXSE. This will improve the development cycle of JXSE applications even more.

JXSE and Equinox Tutorial, Part 1

Aggregated on: Tue May 23 2023 09:45:38 GMT+0000 (Coordinated Universal Time)

Abstract NOTE: As of January 2015, you can integrate JXTA in OSGI through an update site. The WIKI At chaupal.org gives detailed instructions on how to use the new 2.8.x JXSE bundles for OSGI. This extended series of tutorials will cover the various ways that the JAVA P2P framework JXSE (formerly popularly known as JXTA, and currently the most up-to-date JAVA implementation of the JXTA specifications) can be made to work with Equinox (the engine on which Eclipse runs). It would be tempting to replace Equinox with OSGI, and indeed many of the issues covered here will work fine with alternative OSGI implementations such as Apache Felix or Knopflerfish, but I will concentrate on Equinox because it will allow us to do a few things with JXSE that requires a bit more handwork on other OSGI platforms. Besides this, I have tested the code on Equinox alone, so I don't want to get ahead of myself. This tutorial is work in progress, so the document will be re-edited a few times. This tutorial not meant to cover the principles behind P2P in general, and JXTA/JXSE in particular. If you are interested in this, I'd recommend the (free) book Practical Jxta II by Jérôme Verstrynge, or to go through the online manuals for JXTA 2.5, JXSE 2.6 and 2.7. This first tutorial is aimed to get you started with JXSE 2.7x in an Equinox environment. The reader is expected to have a good understanding on developing plugins with the Eclipse IDE. If you are new to Eclipse I would advise you to read the excellent articles on developing plugins by Lars Vogel and brush up on OSGI and Equinox while you're at it.

JFXtras RadialMenu for NetBeans RCP (Part 2)

Aggregated on: Tue May 23 2023 09:15:38 GMT+0000 (Coordinated Universal Time)

this article is part 2 of a tutorial that will walk through adapting an open source javafx radialmenu ( http://jfxtras.org/ ) to replace the netbeans platform system menu. it will build upon both previous tutorials and part 1 that demonstrate complete replacements for the default netbeans swing components using javafx. code examples will feature netbeans platform, javafx and css. part 1 of the article walks through some of the code upgrades necessary for the task. as of this article’s writing the open-source jfxtras radialmenu needed a few upgrades to act as a system menu replacement for a netbeans platform rcp. part 2 will show the specific algorithm and code to then utilize the upgraded radialmenu as described. when complete you should be able to produce a slick radial system menu like this:

A Java Programmer’s Guide to Random Numbers. Part 2: Not just coins and dice

Aggregated on: Tue May 23 2023 05:45:38 GMT+0000 (Coordinated Universal Time)

This is the second in a series of articles about random numbers in Java programs. The series covers the following topics and also serves as an introduction to the random numbers package of the Uncommons Maths library: True Random Numbers and Pseudorandom Numbers Statistical Quality (making sure the dice are not loaded) Performance (because sometimes you really do need half a million random numbers a second) Different kinds of randomness (because not everything can be modelled by tossing a coin) Degrees of Freedom (is every possible outcome actually possible?) Security and Integrity (when not losing money depends on nobody knowing what happens next) Part 1 of this series discussed different kinds of random number generators (RNGs), highlighted the issues with using the default Java RNGs (java.util.Random and java.security.SecureRandom) and introduced the Uncommons Maths library, which provides three fast, high-quality alternative Java RNGs.

JavaFX Goes Mobile

Aggregated on: Tue May 23 2023 05:45:38 GMT+0000 (Coordinated Universal Time)

Today sees the release of JavaFX 1.1, allowing developers to put their JavaFX RIA applications on mobile phones, as well as the desktop. I talked with a few of the folks at Sun, including Param Singh, Senior Director of JavaFX at Sun, John Burkey, JavaFX Architect and Mandini Romani, who runs the JavaFX platform. In this article I'll go through what's included in this release, as well as ask find out a little more about the things in JavaFX that I've wondered about - mostly the integration between Swing, or SWT, and JavaFX.

JavaFX Gets Video Capabilities

Aggregated on: Tue May 23 2023 05:45:38 GMT+0000 (Coordinated Universal Time)

Get ready for high quality video on the screens of your life. Sun has entered into a multi-year agreement with On2 Technologies, to provide immersive media and content on your JavaFX applications. "The JavaFX runtime environment is designed from the ground up to support high fidelity media, empowering content authors to deliver media-rich content and applications across all the screens of your life. On2 shares Sun's vision of driving video convergence across desktops and mobile devices and we look forward to working with On2 to deliver this capability as part of the JavaFX family of products," said Rich Green, executive vice president, Software at Sun. RIAs written in JavaFX will be able to use the On2 video codecs from Fall 2008, at the same time as the 1.0 release of JavaFX desktop (an early access release is expected in July). We'll need to wait until Spring 2009 for JavaFX Mobile and JavaFX TV. The same high resolution video will run across all of these platforms.

IoT's Security Nightmare: Unpatched Devices that Never Die

Aggregated on: Tue May 23 2023 05:15:38 GMT+0000 (Coordinated Universal Time)

As the Internet of Things becomes a ubiquitous idea and a fact of life, what happens to all the aging and increasingly insecure Things? According to Wired's Robert Mcmillan, responding to a recent question on the security of IoT from Dan Geer, this may be a serious problem [1][2]. The solution, Mcmillan suggests, is to design these devices with an expiration date. In other words: they need to be programmed to die. The problem may not be too severe now, but the future of the Internet of Things will look different than it does now. Security will likely loosen, because software will be a part of everything, and it tends to be the case that things mass produced to that degree experience a bit of a drop in quality. That, Mcmillan argues, presents a problem:

Java Enterprise and Desktop: Spot The Difference

Aggregated on: Tue May 23 2023 05:15:38 GMT+0000 (Coordinated Universal Time)

The two main branches of Java development, Enterpise and Desktop, have traditionally been seen as separate skill sets. But some current trends are contributing to blurring the line between the desktop and the web.For years I've been working on desktop Java with Swing and with the Eclipse platform. I've regarded JEE development as a separate activity, targeting the web market. Some changes in the industry have led me to question this assumption. What is an Enterprise Application Anyway? Before we discuss why desktop and enterprise Java aren’t all that different, we should look at what defines an application as an enterprise application
