What I really wanted to do was set a breakpoint and examine the state of the objects at runtime.

Groovy Database Can Be a Powerful Tool There are coders all around the world right now working on some of the most challenging coding problems that are out there. They are all likely relying on using Groovy database at least to some extent as this is a major player in the industry. People from all over the world recognize the true power of Groovy database and all that it can provide to them from a coding perspective, but the fact that it is such a powerful tool should not be ignored. If you want to advance very far with Groovy database at all, you will need to make sure you have a firm grasp on what it is and why it is so useful to coders all around the world. How it Compares to Java Most people are familiar with Java and have likely used it in their coding adventures at some point. It is a primary tool that has helped with the coding of numerous projects that you are likely familiar with already. Java is a great place to get started, but it doesn't necessarily compare so well to Groovy when they go head to head. It depends on what you are trying to get done, but the use of Groovy trumps Java for most developers. The reason is that most developers prefer to work with a system that has been specifically created for them. Groovy is that system. Everything that it offers is crafted with the developer in mind, and most agree that it is more user-friendly from a developer's point of view. This means that you don't have to waste your time trying to figure out how to work the very system that you are just trying to make some progress on in the first place. Java users are frequently frustrated by their inability to get as much done as they might like to because they are constantly running into brick walls when it comes to how they develop the systems that they need to develop. Most people significantly prefer it if they are able to cut away everything else and simply get to the root of the problem that they are working on. Then, and only then, can they truly begin to formulate a strategy that will allow them to create something that the world will gravitate towards. I am a big fan of using SQL in java and C# software. I typically dislike the usage of ORM frameworks like Hibernate. I feel that ORMs tend to hide a lot of issues. They also tend to have a higher learning curve. I am not sure that the ROI on deeply learning an ORM is sufficient enough to use. However, there are a lot of pitfalls that come with being so close to the SQL. The largest of which is proper resource handling. If database connections are not closed properly, the application will soon become starved of available connections. This post contains a simple example of using Groovy Categories to help manage the resource management of database connections. There are a lot more robust solutions (ie: GORM), but sometimes you only need a quick implementation. To accomplish our goal, we will be using a static closure defined below. The OpenDatabase class is merely a container for the closure. I think the final implementation of the code reads nicely because of the name. OpenDatabase.groovy import groovy.sql.Sql class OpenDatabase { def static with = { DbConnection conn, Closure closure -> Sql sql try { sql = conn.getConnection() if (closure) { closure(sql) } } finally { sql.close() } } } The DbConnection class is a simple interface for creating the groovy.sql.Sql object. DbConnection.groovy import groovy.sql.Sql; public interface DbConnection { Sql getConnection(); } Below is the sample usage of these two classes. OpenDatabase.with(dbConnector) { sql -> sql.execute("insert into BLAH...") } The database connection will be closed after closure exits. Simple, easy resource handling. The groovy way. The original article can be found at http://www.greenmoonsoftware.com/2014/04/groovy-database-resource-handling/ Applying Mass Data to Problems One of the upsides to Groovy database handling is that you don't always hear about is the fact that you can apply massive amounts of data to the issues that you are attempting to take care of today. The beauty of this is the fact that much of that data will prove very useful to you as you work on trying to figure out exactly what it is that people want from your projects. The more data you have, and the more data that you can apply, the better the outcome will be for yourself and others. Groovy allows you to input all of the data that you require all at once so you aren't constantly left struggling to try to figure out which steps you need to take next and how you will get things done. Simply use Groovy to get the results that you need, and you will be all set. A large amount of data is always preferable to use because it will help you figure out what is truly going on within the scope of what you are working on. Any single piece of data could be an outlier, but when you have a major data dump to go through, you know that you are getting the most relevant information right away. Endless Possibilities Groovy has made it so much easier for developers to work out what they will do to get their code set up just right that it has truly performed an amazing service that we should all be grateful for. This is why we need to note that the possibilities are virtually endless when working with Groovy and the tools that this service has provided. It is a very big deal when you get your code to sync up just perfectly, and that is what you get when you use the Groovy system. There are now so many people working within the system that it has grown much larger than some of its competitors. That is why we anticipate that many interesting developments are going to come out of it. When you have that many people working that hard all within the same system, you are generally going to get some pretty outstanding results to come out of this. You need to account for that fact and understand that there are numerous upsides to using a system that works just like that. A Great Place for Starters Those who are just taking on the coding world for the first time need to look at Groovy as the kind of place where they can start to hone their skills. It is not necessarily the first area that people necessarily think of when they are looking over different coding programs to get started with, but it is where they should begin. The controls are so much more refined for the kind of person who is just getting started, and that means that it is the ideal training ground for someone who is truly eager to learn the system and get to work within it. People who are just starting their coding journey should be excited to have the resources available to them to get started in this way. It can all prove extremely useful in the long run.

Java is changing the world around us in major ways. Here is how.

Automated deployment doesn't have to be difficult. Learn how to use the Mule management console and Maven to achieve automated deployment.

Netbeans Platform Offshore has received an increased amount of attention given the massive amount of attention placed on the supply chain crisis that has occurred all throughout the world in recent years. Modern ships rely on NetBeans Platform Offshore and similar technologies to help guide them where they need to go. Thus, the world's reliance on Netbeans Platform Offshore could not be more obvious at this time. Better Software Systems Onboard Ships Make Them More Reliable Cargo ships and other naval vessels are very delicate pieces of equipment that can be easily disrupted by a malfunctioning piece of software equipment. If something goes wrong with the Netbeans system onboard, then a ship can be routed in the completely wrong direction from where it was intended to go. Obviously, the world of global commerce simply cannot allow for this to happen, and companies are responding to the need. Software Can Help Maintain Crew Safety Netbeans is being relied upon more than ever for crew safety at this point. After a review of all known marine system models, the Netbeans system was built to incorporate all of the best parts from each system to help promote safe passage and crew safety while on board the ship. At the same time, developers had to ensure that the enhanced security features would not hinder the ship from going where it needed to go. After all, the world of commerce moves faster than ever before these days, and there is no way that slowing the ship too much would be permitted by the companies that own and operate these vessels. They care about their profits and bottom line, and they wouldn't want to give those up too much. Modern ships and rigs have advanced computer systems for dynamic positioning, power generation and distribution, and drilling operations. Software errors in these systems lead to delays and non-productive time, and compromise safety. Marine Cybernetics performs independent testing and verification of computer system software to detect and eliminate such errors and weaknesses using Hardware-In-the-Loop (HIL) testing technology. Centralized Control and Overrides Two important things about the Netbeans system is that it provides both centralized control over the vessel and also allows for human overrides as necessary. If there is ever a situation in which the software program is incorrect in its assumptions or makes an error, humans can jump in and make the necessary corrections to get things right. It is wonderful to see the two things working in tandem, and it provides strong evidence that this is the way forward. Based on our extensive library of marine system models, we build applications and user interfaces for our testers and customers, based on the NetBeans Platform. The modular nature of our simulators and the diversity of test programs and vessel configurations make the NetBeans Platform a natural choice. Coupled with Maven, Hudson and an agile approach to software development, the NetBeans Platform enables us to quickly roll out new applications and adapt to the changing offshore industry. The screenshot above is taken from a Power Plant HIL Simulator, but we also make HIL simulators for Dynamic Positioning, Steering, Propulsion, Thrusters, Drilling Systems, Cranes and other systems. Our database of test programs and procedures is also powered by a NetBeans Platform application. Independently Verified Finally, one more reason to rest easy with the Netbeans system on board is the fact that it has been independently tested and verified. A third-party has been brought in to help ensure that the system is working as designed. That is clearly a very big deal because not every company would be so willing to work with outside auditors to ensure that everything was working as designed, but the makers of Netbeans are perfectly fine with doing exactly that. They want to make sure their systems are the safest and most tested on the planet, and they are not afraid to let another party poke around those systems to discover if this is the case. Continue to check out what Netbeans comes up with next as they are sure to provide the world with very interesting and useful equipment. Could More Useful Onboard Technology Help Supply Chain Issues? Unless you have had your head under a rock for the last several years, you are well aware of the fact that there have been some major supply chain issues that have caused trouble for seaports all throughout the world. Instead of getting things to customers right when they require them, many shipping companies have been woefully behind on getting their shipments to customers as designed. Thus, people are starting to ask if it might be possible to use onboard technology to help get the cargo from ships to where it needs to go much more quickly. Indeed, it does feel like there is some hope that some of the technologies that Netbeans has produced could help prevent some of the hang-ups at ports. This is not to suggest that Netbeans can do it all by itself, but there are plenty of people working on the problem, and it feels like a little extra guidance technology may be exactly what is called for to get the job done. Yes, there are going to need to be even more people hired to keep freight moving where it needs to go, but we cannot forget the fact that there are a lot of people counting on crews to bring their supplies to them in a timely fashion. The best way to reach that goal is to use the most up-to-date technologies in the world to make it happen. Navigation is a must for all shipping concerns, and having the best technologies on board means that one can finally get ships where they need to go. Estimates suggest that literally billions of dollars have been wiped off of the economies of the world because of supply chain issues. The fact that some of this can be remedied by just getting ships where they need to go is a wonderful piece of news for all involved. Tracking Shipping Containers and More Expectations are such that Netbeans may have the ability to track shipping containers and provide other valuable insights into what is going on in the world of shipping. If so, the value that they provide will surely skyrocket. The entire world relies on shipments that are brought to them via the ocean, and any system that can help make that process a bit smoother is going to be lauded as the next great thing when it comes to economic growth and stability. Netbeans is here to help bring that next chapter forward, and we all owe them a debt of gratitude for the work that they are actively doing to help all mankind.

Use this guide to grab eclipse console output effortlessly. After reading it, you'll be able to grab eclipse console output successfully. But before we dive into it, let's start by answering this crucial question: What is the Console in Eclipse? The Console in Eclipse is what will enable you to view the output of the utilities invoked when building a project or the program's output when you run or debug running the application. Typically, you will follow these easy steps to view the output: Click Window > Preferences. Expand C/C++ and Build, then click Console. If you want to display information on the latest project only, use the "Always clear console before building check box" option. Optimize Each Line Of the Eclipse Output In your plugin, if you want to do something with each line of your eclipse output console, for example, write that line to a file or parse it before sending it to your custom eclipse view, you should create a class that implements IConsoleLineTracker, and you should add this extension point to your plugin.xml. [img_assist|nid=1032|title=|desc=The steps are explained well here...|link=none|align=none|width=256|height=192] Now, suppose your class implementing IConsoleLineTracker is this: public class LogTracker implements IConsoleLineTracker { private IConsole m_console; public void dispose() { } public void init(IConsole console) { m_console = console; } public void lineAppended(IRegion region) { try { String line = m_console.getDocument().get(region.getOffset(), region.getLength()); // DO SOMETHING WITH THAT LINE } catch (BadLocationException e) { WrCheck.logError(e); } } } Copy the console output in Eclipse The best method you can use to copy a console is to tell Eclipse to save console output to a file. To do this, you need to go to Run → Debug Configurations on the Eclipse menu. Once you Debug Configurations successfully, then navigate under the Standard Input and Output section, click on the checkbox next to File: and choose the name of the output file to use. Get the full Console in Eclipse Are you trying to get full console in Eclipse? The good news is it's possible to get it. All you need to do is go to Windows --> Preferences --> Run/Debug --> Console and then unchecking "Limit Console Output" which is ON by default. This works on STS any version too. This would help print complete console output. For a Mac, it is Eclipse > Preferences > Run/Debug > Console. View the console log in Eclipse If you want to view the console login to Eclipse: You need to go to Run -> Debug Configurations on the Eclipse menu. Then, under the "Standard Input and Output" section, Click on the checkbox next to "File:", and choose the name of the output file to use. If you check "Append" underneath, console output will be appended to the output file. How do I save data on the console? There will be times when you'll need to save data on the console. To do this, all you need to do is right-click > go to Save button, which is in the Console panel. It will allow you to save the logged messages to a file. In a situation where you have an object logged, then you can use the following steps: Right-click on the object on the console and click Store as a global variable. The output will be visible as "temp1.type in console". Copy (temp1), And paste it to your favorite text editor Install a detached console in Eclipse Want to attach the console to the main eclipse window? Follow these easy steps: Click Window->Perspective-> then go to Reset Perspective to detach it. EFCARDZ TREND REPORTS WEBINARS ZONES DZone > Performance Zone > Remotely Debugging an Eclipse Plugin Upgrade Eclipse Follow the instructions below to upgrade Eclipse: On the toolbar, navigate to Window > Install New Software. Click on Add and add the following URL for the latest build of Eclipse: https://download.eclipse.org/releases/latest. Alternatively, you could add the specific build of Eclipse you want from https://download.eclipse.org/releases/ such as: https://download.eclipse.org/releases/photon/ or go to https://download.eclipse.org/releases/2019-09/. Once the site is added to Eclipse, you can now proceed with the upgrade by navigating to Window > Help > Check for Updates. This basically goes through all the sites under Window > Preferences > Install/Update > Available Software Sites and gathers updated details from the ones that are selected. You should be able to see a pop-up listing the various plugins/tools that require an update. You have the option to select the ones that you need, or you can leave them as is. Then, click Next. Click Next after reviewing the details. You should now see the review license page. Click on the radio button "I accept ...." and click Finish. Remotely Debugging an Eclipse Plugin The Eclipse plugin can be debugged from inside the IDE while in the development phase, but once the plugin is installed in the IDE, we need to debug it remotely for bug resolution. In this quick tutorial, I'm going to explain how to debug an Eclipse plugin remotely. Plugin Project Let's suppose we have developed our simple Hello World plugin and installed it in our IDE. Now, to debug the plugin remotely, please follow the steps below. Step 1 Open the first instance of Eclipse IDE pointing to the workspace where your Hello World plugin project is located. Step 2 Navigate to the eclipse.ini file of your IDE. Here is a screenshot of the location of the file in macOS. Now add the following JVM arguments to the file: 1 -vmargs 2 -Xdebug 3 -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 Step 3 Now, open another instance of the Eclipse IDE (on macOS, use the command open -a -n Eclipse in the terminal). This instance will point to a workspace different from the one which contains the Hello World plugin project. Step 4 Now, in the workspace containing the Hello World plugin project, make the following remote debug configurations/; Navigate Run -> Debug Configurations -> Remote Java Application. Then hit the debug button. Also, do not forget to put break-points in the code of the Hello World plugin to be debugged. Step 5 In the other workspace (which does not contain the Hello World plugin), try to use the Hello World plugin and it will be remotely debugged in the other instance of Eclipse. Conclusion There are Eclipse-based IDEs that have a powerful feature to make ‘variants’ of the same projects. Use the to Build Configurations, which are a powerful feature in Eclipse. They will allow you to make ‘variants’ of a project. The project will share the common things, and you can simply tweak things one way or the other for example to produce a ‘release’ or a ‘debug’ binary of my application without duplicating the project.

If you wonder what a JMF player is, you are in the right spot. We've noticed that many aspiring developers want to try it out but are unsure how it works. Hence, we decided to put together this guide to make things a tad easier for you. package org.jmf.example; import javax.swing.JDialog; import javax.swing.JFrame; import javax.swing.UIManager; import javax.swing.UnsupportedLookAndFeelException; import javax.swing.plaf.metal.MetalLookAndFeel; public class ExampleJMF { public static void main(String[] args) { JFrame.setDefaultLookAndFeelDecorated(true); JDialog.setDefaultLookAndFeelDecorated(true); try { UIManager.setLookAndFeel(new MetalLookAndFeel()); } catch(UnsupportedLookAndFeelException e) { e.printStackTrace(); } new exampleFrame(); } } But before we dive into it, let's answer this crucial question: What is Java? Java is a high-level language that programmers use to develop projects with few implementation dependencies. Java has transformed the web in many ways. A vast majority of online tools that we use today were built on Java. That includes websites mobile apps and multimedia playback platforms. This programming language has come a long way. This year it will be 27 years since James Gosling developed it. What is a Java Media Framework JMF is an API that enables you to play, process, and capture media audio and video. Whether you want to transmit or receive live media broadcasts and conduct videoconferences, you can easily do it thanks to this API. All thanks to RTP ”Real-time Transport Protocol of the JMF. A JMF is a straightforward player that encapsulates your multimedia component and allows you to control your player. It also offers methods that enable you to acquire necessary resources and query the current state. These are tools you will use to build page objects. For instance, if you want to scan the page and create a class. Here is what Java Media Framework can do: A multifunctional tool A JMF comes in handy, especially if you're looking for a tool that can scan a page and build a class. You can also use it to create prototype code and later build a robust application. Instrumentalization A lot of what you read about the topic of Observability mentions the benefits and potential of analyzing data, but little about how you collect it. This process is called “instrumentation” and broadly involves collecting events in infrastructure and code that include metrics, logs, and traces. There are of course dozens of methods, frameworks, and tools to help you collect the events that are important to you, and this post begins a series looking at some of those. This post focuses on introductory concepts, setting up the dependencies needed, and generating some basic metrics. Later posts will take these concepts further. An Introduction to Metrics Data Different vendors and open source projects created their own ways to represent the event data they collect. While this remains true, there are increased efforts to create portable standards that everyone can use and add their features on top of but retain interoperability. The key project is OpenTelemetry from the Cloud Native Computing Foundation (CNCF). This blog series will use the OpenTelemetry specification and SDKs, but collect and export a variety of the formats it handles. The Application Example The example for this post is an ExpressJS application that serves API endpoints and exports Prometheus-compatible metrics. The tutorial starts by adding basic instrumentation and sending metrics to a Prometheus backend, then adds more, and adds the Chronosphere collector. You can find the full and final code on GitHub. Install and Setup ExpressJS ExpressJS provides a lot of boilerplate for creating a JavaScript application that serves HTTP endpoints, so it is a great starting point. Add it to a new project by following the install steps. Capture media streams Not only does the JMF allows you to play music, but you can use it to capture media content as well. And all this will happen while you process and capture it from a source to a destination. You'll then identify each media stream by its content format. From there, the JMF will present the content of that specific video stream. Each media stream will have at least one or more tracks that you can play. Identify each media stream by location You can either identify your media stream by using uniform resource locators (URLs) or media locators. It doesn't matter how you locate them. What matters most is that you wouldn't struggle to identify each media stream. Process Time Bases and Clocks You can also play time-based media, or capture them at an accurate time. To achieve this, JMF requires time-bases and clocks. So, without a thorough understanding of time bases and clocks, you won't be able to work with JMF. While at it, use the below 1. Eliminate Unused Tables Usually, when you remove or deactivate a plugin, all the database tables remain. This can be a good thing, as you retain all the user information, preferences, and other data. However, in most cases, you’re left with a cumbersome dataset that may bring your server’s performance down. If you’re using WordPress, you can get rid of leftover tables by installing a plugin called Plugins Garbage Collector. It scans your database for any unused tables, and you can delete the ones that you know aren’t needed. A more hands-on approach is finding inactive tables using the UPDATE_TIME string. 2. Create an Execution Plan The execution plan’s main goal is to display the various methods of retrieving data by containing the operation's type and order when creating a query. If you’re not familiar with execution plans, here’s a video going through the basics. The typical execution plan includes the following: Types of operations Order of operations Indexes to use Row count estimates from stats Row count actual from results 3. Use Proper Indexing Indexing allows for faster access to the database and speeds up the queries. If you don’t use indexes at all, then processing the queries becomes painfully slow. Yet, over-indexing your database is also ineffective. Unfortunately, there isn’t a golden rule for optimizing your database the right way. However, with some trial and error, your database benefits from an index system. 4. Avoid Coding Loops A SQL query that runs more than once is inefficient and can cause unnecessary performance issues, which pile up quickly, especially with large datasets. In essence, moving a query outside a loop with the goal of it executing only once is the way to go. There are a couple of nifty solutions to achieve this. Use JOIN and GROUP BY to select data from multiple tables and have the database perform the counting with a single query. This is especially effective for multiple queries, including COUNT and MAX clauses. 5. Get Rid of Correlated Subqueries Correlated subqueries are essentially coding loops. The subquery runs row-by-row until it satisfies the parent statement. This method of processing is useful when the outcome relies on multi-part answer validation. You can avoid the correlated subqueries by using JOIN clauses, which makes the query run more efficiently. Essentially, this method replaces WHERE and removes the necessity to execute the subquery for each row separa 6. Avoid * Queries The ultimate goal of every query is to retrieve relevant data for maximum efficiency. However, it’s relatively common to use SELECT * clauses when creating a query resulting in unnecessary data. While it doesn’t play a massive role in the performance of small datasets, it can leave a significant dent in larger ones. Selecting the data sparingly helps with optimizing the query speed and reduces resource usage. A quick way to turn this issue around is using the LIMIT clause instead of SELECT *. This way, you limit the output of the query results unless you do need the entire dataset retrieved by the query.

Tracking open-source data users is harder than you think, but the Eclipse Foundation is trying to make it happen

It has often been remarked that IE is a headache for developers -- in part because Microsoft tends to prefer its own versions of web standards. With IE10, take advantage of the evolution of web standards with even more HTML5 access and features. The Retirement of Internet Explorer On the other hand, quite a few 'modern' web technologies -- including XHR -- were originally Microsoft innovations, only later adopted by..well, everyone else. Today, Microsoft has a brand new version, known as Microsoft Edge, as Internet Explorer 11 is set to be retired on June 15th, 2022, meaning there will no longer be support provided for users or developers alike. While in some fundamental ways, IE9 actually handled what it was meant to handle fairly well -- Chakra, for example, shows that IE9 uses less CPU time and RAM than Chrome, under Windows. Even today, Microsoft Edge clocks in at using around 600-800 MB of RAM compared to Google Chrome's 1.4 GB just for one browser window. Of course, in terms of support for emerging web standards, IE9 lagged well behind its competitors. IE9 may have done some things well, but it did not do as many things as other browsers do (even if it did some cool things, like pinned sites that other browsers don't). Advantages of Using IE10 While using Internet Explorer has not been in style for more than a decade, it is still used by many people from around the world, especially those who do not have access to updated software or hardware. Even if IE10 is not your preferred browser to work in, ensuring any website or software application that is programmed is compatible with Internet Explorer 10 is essential. Some of the advantages of using IE10 include: Speed: IE10 has been updated for improved performance and speed. With Internet Explorer 10, you can enjoy fast loading speeds when browsing and when developing projects of your own. User-friendly: Fortunately, the latest version of Internet Explorer is extremely user-friendly with an updated interface for easy and straightforward navigation. Tab implementation: With Internet Explorer 10, you can also use tabs easily and with minimal effort. Tab implementation helps developers to work in various areas with numerous websites open simultaneously without closing another window. Pinned sites: Use the new 'Pinned Sites' feature from Internet Explorer 10 to keep track of favorite websites or websites that are useful for resources and tools while programming. Memory usage: If you are concerned about how much memory your browser is using, IE10 is typically a safe and smaller choice compared to alternative browsers such as Google Chrome. On average, Google Chrome can use anywhere between 300 MB and 1GB of memory just while browsing online. With Internet Explorer 10, you have the ability to cut the memory usage in half in most instances. Flash add-on: There are enhanced add-ons available for Flash with Internet Explorer 10 for those who are interested in loading web pages with Flash or working with Flash during development. Development tools: If you enjoyed Internet Explorer 9's Developer Tools, you will be relieved to know that Internet Explorer 10 has kept the same F12 Developer Tools for quick and easy access. However, keep in mind that it is difficult to test a site that has been hosted on your machine with Internet Explorer 10 without a manual workaround. When using Developer Tools, Internet Explorer 10 automatically switches the pages you are working in into a compatibility mode by default, making it a bit more difficult to test pages locally without uploading them to your own web server(s). Drawbacks of IE10 Unfortunately, as with any piece of software, there are also drawbacks to using Internet Explorer 10, even for those who are truly committed to Microsoft's creations. The most notable drawbacks of using IE10 to program, develop, or browse include: Lack of Flash: With Internet Explorer 10, there is no built-in Flash player or Flash support, which can make it difficult to load websites with Flash players or with Flash animations built-in to the site itself. While Flash is not inherently supported by Internet Explorer 10, it is possible to use and access Flash-based websites and applications with an Internet Explorer 10 add-on designed for enhanced Flash performance. Lack of PDF support: Unfortunately, it is not possible to load previews or entire PDFs when using Internet Explorer, even when you are using the most updated version of the browser. There is no PDF reader with IE10 available, which can make it difficult to access a variety of documents, for work or for personal use. Outdated: Now that Internet Explorer 10 is being retired, it is considered an outdated piece of software. With little to no future updates being rolled out by Microsoft, Internet Explorer 10 will no longer provide additional features, add-ons, or plugins that may be relevant to the development or working with HTML5. IE10: Now With More HTML5 But Microsoft promised big changes for IE10, and made available a developer preview to prove it. Diving into HTML5 can provide an array of new features for developers and designers alike. This preview includes considerably expanded HTML5 support, and (most impressive to me) leverages hardware acceleration (ala Chakra) to speed up graphical technologies (e.g., SVG, CSS3 transforms) -- check out the embedded video in the full announcement. Microsoft highlighted a few specific HTML5 features, newly available in this developer preview: Cross-Origin Resource Sharing (CORS) for safe use of XMLHttpRequest across domains. File API Writer support for blobBuilder allowing manipulation of large binary objects in script in the browser. Support for JavaScript typed arrays for efficient storage and manipulation of typed data. CSS user-select property to control how end-users select elements in a Web page or application. Support for HTML5 video text captioning, including time-code, placement, and captioning file formats. Great operating system integration for various operating systems available today A Metro mode is also available for those working from touchscreen smartphones and tablet devices to browse and/or to develop Additional HTML 5 features supported by IE10 include: File reader API Forms validation Drag and drop solutions IFrame support for sandbox attributes CSS3 gradients Flexbox Improvements that have been made to the IE10 browser that are beneficial to developers include: The ability to run script (Web Workers API) in the background with frontend impact JavaScript 5 support (adds the method JSON.parse to objects) The browser's Flash player is no longer a plugin, but is a built-in element of the browser itself. The "Do Not Track" feature is automatically enabled by default, which can prevent ad trackers from harnessing web browsing data from users. The full documentation of IE10's HTML5 support is here, and the rest of the developer documentation here. While it seems like just yesterday, on October 26th, 2012, Microsoft released Internet Explorer 10, it's time for support has come to an end. It is important to keep in mind that further support will no longer be available for any versions of Microsoft's Internet Explorer following the official retirement of the browser on June 15th, 2022.

Animation Brings a Whole New World to Life Where would we be without animators helping us see the world in a whole new light? It seems that we easily forget the hard work that these people do, and that is truly a tragedy. There are so many people helping us see the world for the way that it truly is, and we should be thankful and respectful of the hard work that they are doing. That is why we also have to ask ourselves if we should be using CSS3 Transitions or jQuery Animate when looking for the right program to do our animation work in. You might think that animation is just something used to create children's movies and television shows, but that isn’t quite right. It has a wide range of uses in our world today (more on this later), and we are increasingly coming to rely on it to make critical decisions about how we move forward on some of the most important decisions that we have to make to keep our world moving forward the way that we want it to. Take some time to step back and recognize all that animation has brought us, and this will help you better understand why there are a lot of people who are pushing to figure out which software programs can bring them the best animation outcomes. Rich Bradshaw has written a detailed tutorial series on CSS Transitions, Transforms, and Animation. That alone is worth reading; but in case you weren't convinced, Rich also put together a little (and maybe a little unfair) performance comparison: A head to head comparison of CSS transitions and jQuery's animate. Rather than setting a timer to run repeatedly, transitions are handled natively by the browser. In my rather unscientific testing, transitions are always quicker, running with a higher frame rate, especially with high numbers of elements. They also have the advantage that colours can be animated easily, rather than having to rely on plugins. Putting it All to the Test The best way to compare the two programs against one another is to put them through a series of simulated tests that allow each program to prove what it has going for it. Believe it or not, that is exactly what some people have done. They work with the two programs to see how they adapt and react when put under various testing conditions. By doing exactly that, the programs must prove themselves in the sense that they are forced to show that they can keep up with rapid changes and shifts in the dynamics of the work thrown at them. These tests can all be sped up by using computer simulations to run the tests instead of putting actual work done by a human being through the testing period. You will find that there is a lot to be gained by going through all of this and figuring out just how much each system can potentially get through. You don't want to use something that is sub-par compared to the other programs on offer out there, and that is why we are all so grateful that there are people who are willing to work with both programs to test them and see what the ultimate outcome really is for each. Unsurprising Results You should not be shocked to learn that CSS3 Transitions is the better program to use. It has a more seamless transition from image to image, and the speed with which it can process all of that data is truly amazing as well. The fact that there are multiple programs available for us to choose from is a great thing, but there is really no competition between CSS3 Transitions and jQuery Animate. The CSS3 Transitions program has been around for a lot longer, and it has the ability to get results from its users much more easily. The results probably won't surprise you, and the conclusion is inevitable ('use CSS3 for animation when you can') but Rich's analysis (scroll down), using the Timeline view in the Webkit Inspector, is pretty neat: (Actually, the Timeline is pretty neat, period. I didn't know about it until now..sweet.) So check out Rich's test and performance discussion, and maybe use Webkit Inspector's Timeline for performance fine-tuning in the future. Animation Into the Future The tools that are used in the world of animation are going to continue to be called upon to help creators do the challenging work that they do. The demand for animated films and television series has not ceased, but the usefulness of animation goes far beyond being entertained. There are uses for animation in simulations of all kinds. Even the military uses animation to simulate certain battlefield conditions and other concerns that they know are relevant to their operations. It is something that has helped them sort out how they can best move forward with their plan of action whenever the need arises. Put another way, the military uses animation to make sure they are never caught off guard. Courtrooms are seeing an increasing amount of animation used in presentations put on both by prosecutors and defense counsel alike. They make reenactments of various aspects of an alleged crime using animation to help a jury see how they claim that things happened from their point of view. There are a lot of reasons why this helps juries to understand their point of view more completely. CSS3 technology is helping to make the use of animation more widespread and available to a larger number of people across all walks of life. It appears likely that this trend will continue, and there are many people who are counting on using CSS3 technology for several projects that they have in the works at this time. We should all celebrate the fact that such technology is making animation more accessible. Using the Best Programs Doesn’t Have to Be Costly One more thing to keep in mind when you look for the best programs for animation purposes is this: They don’t have to be costly. Many programs are free and/or open-source. Even the ones that you have to pay for aren’t necessarily wildly expensive. They provide a huge ROI when you put them to use, and that alone should get you to understand why they are so important to use. Make sure you consider this and consider the options that are before you when it comes to selecting an animation program that will do the work you need it to do. The last thing in the world that you want to have to happen is to produce lower-quality animation just because you insisted on trying to save a few dollars by going with a less expensive animation program.

I'm Stefano Chiappa and I'm from Milan (Italy). I work at Prisma Engineering (http://www.prisma-eng.com/) as Lead Software Engineer of the Simulator User Interface Team. AirMosaic is an application on the NetBeans Platform for controling Prisma's UeSIM, which is a multi mobile simulator. The UeSIM is basically a server with some antennas able to connect to a base station and simulate a population of mobiles doing some basic or complex Test Procedures. These procedures can be "real-world" applications such as HTTP, FTP, Mail, VOIP calls or protocol-dependent procedures such as attachment/detachment to the Core Network. Several mobile technologies are supported: LTE/UMTS/GSM. The images below are taken from LTE version. Why VoIP calls are more popular than ever The AirMosaic technology that is used within the Netbeans system is something that is generating a lot of buzz and helping companies get work done that they must surely have believed would take much longer than it has. One area that AirMosaic has come into play very rapidly is in the realm of VoIP calls. VoIP stands for "Voice over Internet Provider", and this refers to the way that many calls are received in the modern office environment these days. A few reasons why office managers prefer VoIP over other options is because: Prices are lower - Generally speaking, the cost of VoIP calls are lower in total. You don't have to pay some of the additional costs that come with international calls or other types of calls when using a VoIP system. Instead, you receive a lower overall cost because the cost is usually a standard and flat rate. VoIP meshes well with existing and emerging technology - VoIP works well with both existing technologies as well as those that are emerging on the scene at this time. Thus, office managers and anyone else who is involved in the phone purchasing process for an office will often find VoIP causes them the fewest headaches as far as combining it with what they already have or what is soon coming down the line. Excellent call quality - It is hard to beat the call quality that you receive with a VoIP system. The calls are crisper, clearer, and provide the consistency that every office is looking for. You really can't go wrong with a VoIP system like this. In the first step a population of mobiles is created. It is possible to edit a huge amount of parameters related to the mobile device hardware and the user subscription related to the SIM. The following image shows the editing of this mobile database, which is performed inside a NetBeans editor and properties window (click to enlarge the images): Once a Mobile population has been created, it is possible to create a scenario (navigator window) where is described what a single or group of mobiles will do. The available test procedures are collected and grouped inside a navigator window on the left bottom side, where you can see some of the available tests: When the scenario has been created, it is possible run it through the UeSIM hardware. This is displayed in the next image: On the upper left side of the image, AirMosaic displays, through some gears, the currently running test. We used a central editor window to display some counters of the running simulation. It is possible to choose the displayed counters by checking a node of the tree on the left side of the window. On the lower side of the application, there is an output window that displays the sequence of events happening during the simulation. Once a scenario has been completed, the scenario window, on the application's top left, shows a green circle to indicate that the test has been completed successfully, as you can see in the next image: Some plots can be drawn for each counter available. It is possible to put different counters on the same plot or on different plots. This is displayed in the next image: At the end of a test, it is possible to generate a report, save it as a PDF, or send it by mail automatically, as shown in image below: This is basically what the application does. Several features are still in development, of course! AirMosaic Runs Simulations For Phone Testing Purposes Did you know that it is important to test the phone systems within your office on a regular basis? You should do so not only because you need to make sure the phones are working so that customers can call in, but also to make sure there aren't any fraudsters trying to take advantage of a vulnerable phone system. Believe it or not, there are fraud cases in which the criminals will attack a phone system set up by a company for their own malicious purposes. Fraudulent calls can ring up huge expenses for companies that are difficult to repay. Obviously, this is not an ideal situation for anyone, and it is best to avoid such scenarios by testing the phones on a regular basis to make sure that there isn't anyone in the system who shouldn't be there. AirMosaic can run sweeping tests of phone systems to try to detect problems like this. What AirMosaic will do is run their sweeping tests to detect any anomalies within the system and alert you to what is going on. They will even let you know if there are phone calls within the system being placed by people who work for you that shouldn't be placed. It would be incredibly challenging to run all of these tests by yourself, and that is why so many are using AirMosaic instead. They see the value of adding a little extra security to their phone systems, and they realize that the only true way to do so is to run a program like this that can detect any problems. Data is Generated That Can be Scanned Finally, AirMosaic produces a list of data on the phones that it has scanned which you can view on your own time. Look over every piece of information that the system found in order to figure out what is going on with the phones that it has identified as perhaps having a problem. AirMosaic is very good at narrowing down the list for you so you don't waste your time trying to go through all of this information on your own. Instead, you rely on AirMosaic to help you out, and then you simply review the data that it discovered in order to get a better idea of what may be happening within your system. By isolating the phones that appear to have a problem, the AirMosaic system makes it easier for you to see which specific phones you will look at and why they may be having some issues. Users sincerely appreciate this because it means that they can finally receive the data that they require to send in their team of IT experts to fix the problem. It takes a little bit of time and effort, but it is worth the trouble when you identify the problem and get people involved who can help. Save your company from the risk of being vulnerable to attack over the phone system. Use AirMosaic to run some tests today.

Released back in 2012, Neo4j 1.8.M03 introduced the RELATE clause, a two-step dance of MATCH or CREATE. Also, new Transaction support in the shell lets you call for a do-over in case you misstep. RELATE, a Subgraph Match-Maker A RELATE clause looks a lot like a MATCH clause — the ASCII-art of graph traversals — but behaves differently when there isn't a satisfying subgraph. When there is no match, RELATE will create the needed Relationships and even intervening Nodes. RELATE ensures that the subgraph exists. So, I just fetched myself a coffee. Let's say I want to keep track of how often I visit 3 Bees Coffee. I could carve notches on my desk, but I've already ruined one Ikea desk that way. Being graph-minded, I immediately realize that I'll be curious about deeper questions regarding all the places I visit. I will, of course, evolve a graph mini-app. Neo4j 1.8.M01 introduced the CREATE clause, so I'll create me and the coffee shop: CREATE me = {name:"Andreas"}, `3bees` = {name: "3 Bees Coffee"} (Note the back ticks around 3bees because the term starts with a number) To record that I have visited 3 Bees Coffee, I could add a relationship at the same time: CREATE me = {name:"Andreas"}, `3bees` = {name: "3 Bees Coffee"}, me-[:VISITS]->`3bees` Of course, I will be re-visiting coffee shops more often than going to newly opened shops. I already know about me, and will usually know about the coffee shop, so what I really want to do is just create the Relationship. START me=node(1), coffee=node(2) CREATE me-[:VISITS]-coffee Easy as pie. Mmm pie. Create a record for me, create a record for a shop, and whenever I visit a shop, create a Relationship. Because I want to keep track of the frequency of my visits, I suddenly have a problem: I don't want to create a Relationship every time, but get one if it exists and just update a property on it. Cypher is declarative. There is no spoon, I mean 'IF'. So we turn to our friendly match-making RELATE clause: START me=node(1), coffee=node(2) RELATE me-[v:VISITS]-coffee return v That'll match the VISITS if it exists, or create one if it doesn't. To update the visits, I can convert the RETURN into a WITH to tack on a SET clause like so: START me=node(1), coffee=node(2) RELATE me-[v:VISITS]-coffee WITH v SET v.visits=(v.visits +1) RETURN v OK, one last detail to adjust: the classic initial condition problem. If RELATE happened to create a new Relationship, it won't yet have a visits Property. We'll use COALESCE to ignore v.visits if it is null, then add 1: START me=node(1), coffee=node(3) RELATE me-[v:VISITS]-coffee WITH v SET v.visits=(coalesce(v.visits?,0)+1) return v Ah, now I have even more motivation to take coffee breaks. The RELATE clause is powerful fun. Get yourself a cup of coffee, then sit down to peruse the Neo4j Manual section on Cypher RELATE to learn more. And, check on my coffee consumption in the Neo4j Live console, where you can play around with RELATE. Transactional Shell Prior to this release, every query issued in the Neo4j shell (whether command-line or in Webadmin) created a transaction when needed. Now, you have control over transactions with some new shell commands: begin transaction, commit, and rollback. These let you practice your new Cypher dance moves without worrying about falling on your face and taking your database down with you. As usual, look to the Neo4j Manual for the details. Now that we’ve looked back in time, let’s see what Neo4j can do better than SQL. SQL is an impressive query language but there are things that Cypher handles so much better. Whereas SQL started as a single table query language, support was added later for geospatial data and for XML and JSON as well. XML is primarily used for displaying documents on web pages. It uses customized markup languages that are user-defined. JSON reads data from web servers in order to display it online. When dealing with relational databases which are built on tables, JOINs make the connections. So how does this relate to Neo4j? Well, Neo4j is designed to handle product recommendation engines as well as supply management and personalizing customer experience. And Cypher’s graph query language allows you to extract data from graphs. It’s essentially SQL for graphs. Cypher is easy to use and understand. It’s designed for graphs. It borrows from other languages such as Python and is a powerful, full-featured modern language perfect for data analysts and subject matter experts who need to extract meaningful data by reading and writing queries themselves if need be. You don’t need to be a developer to get the benefits from Cypher. A feature of graph databases is that their searches are schema-free. Or at least optional. By not having a fixed schema you can develop the relationships, add attribute types and develop your data as you go. This provides extreme levels of flexibility when developing applications. SQL Path Patterns Query Using path patterns which is an advanced feature, you can have a product that points to a list of categories. With a deep hierarchy, one which you don’t know the depth of yet, you can insert a “*” to find arbitrary linked relationships right to the root directory. But you can limit it to a set number of relationships as well as categories. This is all easily achieved in Cypher but requires linking together a chain of queries in SQL. Each level must be spelled out in the query to the limit that is needed. A cumbersome and time-intensive process, especially when you don’t necessarily know how many categories you’re going to end up with anyway. Find All Cycles in a Directed Graph If you wish to find loops, where a loop leads back to the same person or thing over again, path patterns will determine the outcome. Using MATCH path = (p:Person)-[*3..10]-(p), one can look for 5 hops ending with the person you started with. Not only is the data available in a table but it can be generated visually. And that in essence is what you get with Cypher; a powerful much more user-friendly tool that is purpose-built to provide graph queries in a format that the user can manipulate to show relationships without being bogged down in endless hours of programming and validation. Combine Reads and Writes If you’re familiar with SQL, you need to support Reads and Writes by using insert statements or insert from select. Unfortunately, that’s where it ends. Cypher does the heavy lifting and combines reads and writes in a single query. So, you can update the database while simultaneously fetching data. The benefits of Cypher over SQL don’t end there but I’m sure you get the point. Relate Yourself Neo4j 1.8.M03 is available for immediate download in the usual places.

With IntelliJ IDEA supporting a fully-functional integration with Maven, you can automate your entire building process. The result is that you can create a new Maven project as well as easily handle multi-module projects. Netbeans IDE on the other hand, simplifies the development of mobile applications as well as web and desktop applications using Java and HTML5. So imagine my surprise when some weeks ago, I saw a colleague fighting IntelliJ's Maven support. A dependency was not detected by IntelliJ's Maven support and to fix it, he had to remove the dependency from the POM, save it, add it back to the POM and save it again. Hmmm... somehow not quite optimal. This was the reason for me to take a look at IntelliJ's Maven support and compare some points with the support provided by NetBeans. Let’s look first at how IntelliJ IDEA can support an integration with Maven that is fully functional. This will assist you in automating the whole build. It doesn’t matter whether you wish to create a totally new Maven project, synchronize with an existing open project or add Maven support to existing IntelliJ IDEA projects. You can also manage projects that are multi-module. Creating New Maven Projects These are the steps I’d follow to create a new Maven Project. If you’re starting from scratch and there’s no project open currently in IntelliJ IDEA, go to the Welcome screen and click on New Project. Alternatively, you can select File and then create a new project for the main menu. Once you’ve created your new project, you must name it and if you require it, change its location. You’ll want to create the Git repository, so select the new project for placement under version control. Just be aware that you can do this at any time later in the build. Don’t forget to tick the box. Your project requires a language selection, so do that as well as add any other languages you may want via plugins. You do this by clicking “App>general add”. Under "build system", select Maven followed by specifying the project’s SDK. Or, you can go with the default or JDK. While it is not necessary, it’s a good idea to have a file with a basic sample code, so tick the “add sample code” box. Don’t neglect to specify Maven’s coordinates, which are included in the pom.xml file. You’ll find these in the advanced settings where a new project package is identified in the Groupid box and the project name is specified via the Artifactid box contents. Maven naming conventions follow Jav’s package name rules. This is in the format of a reversed domain name that you control e.g. org.apache.maven. While the naming conventions are not enforced, you’ll have a hard time getting names that don’t follow the rules in the Maven central repository, especially if it is a single word used for group IDs. When you’ve finished your selections, then click “create”. Handling Maven Projects If you open a Maven project in IntelliJ, IntelliJ still generates a default project folder (".idea") and file (".iml"). This means IntelliJ must always ensure that data in the POM is kept in sync with its proprietary structures. However, IntelliJ only handles one direction. Changes in the POM are recognized and the project settings are in sync most times. But if you change something in the project settings, these changes are not reflected in the POM. So, as my colleague experienced, you have to do it twice. Also, IntelliJ lists the "target" folder and ".idea" project settings folder in the logical project view, which is not useful most of the time. In IntelliJIDEA, the Maven project pom.xml file has a compiler included as well as the target Java version. There’s also a Maven tool window and any dependencies that are required to start work. Just bear in mind that the version of Java that is specified in the pom.xml file will, in all likelihood, override the "JDK for importer" option’s specification version. You can find this in the Maven settings. Configure Maven Settings To make things easier, configure your Maven settings before opening new projects. Configuring IntelliJ IDEA to display the Maven settings prior to opening an existing project that is being opened for the first time in IntelliJ IDEA is done at the application level. Once set, they’ll appear for any new project that you open. On the Welcome screen, “All settings” under the customize option. You can also access it from the main menu by selecting “file”, then “new project setup” followed by “preferences for new projects.” In the “preferences” dialog under settings, choose “build”, then “execution”. Under deployment, select Maven as your option under “build tools.” Now go to the Maven settings dialog and make the selection “Show settings dialog for new Maven projects”. You can then click OK and your changes will be saved for all future projects. What this does is, each time you open new projects, the Maven settings dialog is displayed by IntelliJ IDEA and you can then specify the local Maven repository’s location as well as a user settings file. In contrast, NetBeans uses the POM for pretty much everything. The Maven POM file defines the project, as shown below. If you change something in the project settings, it is directly stored in the POM. Only in rare cases, e.g., if you redefine actions, does NetBeans need to create a specific file. NetBeans only shows important information in the Projects window, as shown above. However, if you do want to see the Maven "target" folder, you can easily switch to the Files tab: Building Maven Projects When you build a Maven project in IntelliJ, with the default IDE commands, Maven is not used for the build process. The same goes for tests. If you are using different profiles for local development and your continuous integration server, you have to use Intellij's Maven integration tab to build and test your project with Maven. This is really ugly because you cannot use all the shortcuts that make life easier. NetBeans uses Maven for all that. You can simply press F11 or use the default toolbar button or menu item to build your applications with Maven. This same action works whether you are using Maven, a plain NetBeans Ant build script, or Gradle. It’s always the same consistent procedure. You can even change the Maven command that is used to build the project via F11. You are completely free to configure what you need: Executing Maven Goals Running Maven goals in IntelliJ displays a dialog with just two text fields and you have to type all the Maven parameters by hand. Hey man, it could be so much easier. Running a custom goal in NetBeans gives you a fantastic dialog with lots of possibilities. You can choose the profile, add properties, and even save everything to run it again later. This saves a lot of work. Conclusion There are many smaller issues that show that NetBeans has a smoother Maven integration than offered by IntelliJ. My impression is that IntelliJ's Maven support is just an extension to its default project management system since It still needs the default IntelliJ project folders and files. Meanwhile, NetBeans provides a much deeper and more complete integration. One more thing. I’m not an IntelliJ user so please forgive me if there is a mistake in my observations. I'm also not trying to start a new IDE war. What I want to do by means of this article is to get readers to think out of the box. If you are familiar with your IDE, that is great. If you are productive with your IDE, that is great. But if you think an IDE needs to be expensive in order to be a good product, you are totally wrong and should definitely give NetBeans a try.

While a lot of databases have been created listing information in a table format, the web isn't set up in a tabular style. Neither is plenty of data in a variety of formats that the web uses. However, many databases are still using tables, because many web developers feel that tables handle plenty of data better than any other structure. Others feel that the data tables known as RDB should be converted to RDF, a format used to gather an even wider array of metadata across the worldwide web. The ability to convert to RDF will be extremely beneficial as technology advances to Artificial Intelligence AI and beyond. What is an RDB? RDB stands for a Relational Database. An RDB is a collective set of multiple data sets organized by tables, columns, or records. An RDB establishes a well-defined relationship between database tables. The tables communicate to share information that makes it possible to search for data, organize, and report. RDB is derived from the mathematical function concept of mapping data sets as developed by Edgar R. Codd. RDBs use Structured Query Language, SQL.SQL is a standard user application that provides an easy programming interface for database interaction. RDBs organize data with each table known as a relation which contains columns. Each table row, or record, contains a unique data instance defined for a corresponding column category. The data and record characteristics relate to at least one record to form functional dependencies. RDB performs "select", "project" and "join" database operations, where select is used for data retrieval, identifying data attributes, and combining relations. Those who prefer to use RDBs do so because of the advantages, including easy extensibility or scalability, new technology performance, and data security. What is RDF? RDF is primarily used to provide information or metadata for data available on the Internet. RDF provides the methodology for specifying, structuring, and transferring metadata, and provides the basic XML syntax for software applications to exchange or use that information. The URI/URL provides the location of that data. RDF stands for Resource Description Framework and is a standard for describing web resources and data interchange, developed and standardized by the World Wide Web Consortium, W3C with Xtensible Markup Language (XML) and Uniform Resource Identifier (URI) serving as its distribution standards. Typically, RDF provides basic information and attributes about an Internet-based object, such as the name of the author, Web page keywords, object creation or editing data, or the sitemap. While there are many conventional tools for dealing with data and more specifically for dealing with the relationships between data, RDF is the easiest, most expressive, and most powerful standard to date. The overall informational value is much greater because context or intent can be inferred. RDF presents small chunks of information in a form that infers meaning. This can include rules about how the data should be interpreted. Resource Description Framework, RDF, is the standard for encoding metadata and other structured information on the Semantic Web. Semanticization Data With all the semantic standards and database-centered HTML5 APIs and a W3C standard that calls for implementations, this is an exciting time for data on the web. It's time to embrace RDF with the capacity to start pulling relational data into the semantic web! The Purpose of RDBMS The software used to store, manage, query, and retrieve data stored in a relational database is called a Relational Database Management System, or RDBMS. The RDBMS provides an interface between users and applications with the database. It also provides administrative functions for managing data storage, performance, and access. Semanticization, or giving meaning to, all data can be done in two stages. First, construct a web of meanings, not documents -- as Sir Tim Berners-Lee has always wanted, and as the RDF, Resource Description Framework seeks to do. Second, fit all tabular data into the web whether legitimately or not. This second step is less exciting than the first because plenty of tabular data is not ideally tabular. In these cases, the second step is rather backward-looking. However, it is no less necessary than the first for two reasons: Converting everything RDBMS to RDF is not even close to worth it Much data ought not to be converted to RDF All of this data still needs to talk to the web, which means it needs to be translated into a webby structure, ideally RDF. The easiest way to translate without conversion is, of course, just plain mapping. But mapping two rather different structures to one another is no small undertaking or trivial task. That's why there's a whole W3C Working Group devoted to devising a mapping language and actual mapping of relational data to RDF. Sir Tim offers this insight into the RDF-RDBMS relation, cutting through questions that might otherwise be couched in domain-inappropriate terms (like 'is the RDF model an entity-relationship model'): Relational database systems manage RDF data, but in a specialized way. In a table, there are many records with the same set of properties. An individual cell (which corresponds to an RDF property) is not often thought of on its own. SQL queries can join tables and extract data from tables, and the result is generally a table. So, the practical use for which RDB software is used is typically optimized for doing operations with a small number of tables, some of which may have a large number of elements. Because relational databases are species of the genus described by RDF, the basic mapping model is as follows: a record is an RDF node; the field (column) name is RDF propertyType; and the record field (table cell) is a value. So far, so straightforward. Of course, the implementations usually wander pretty far from the original concept. That's why mapping actual RDBMS to RDF takes a bit of dirty work. RDB2RDF Enter RDB2RDF. The RDB2RDF WG is doing the dirty work. Back in 2005, when the Group was still an Incubator, they published a detailed survey of then-current approaches to mapping relational databases to RDF. This survey served as the starting point for typically extensive discussion and debate, which culminated in two Candidate Recommendations: The RDB to RDF mapping language: R2RML The Relational-to-RDF mapping itself Many techniques and tools have been proposed to enable the publication of relational data on the web in RDF. RDB-to-RDF methods are one of the keys to populating the web of data by unlocking the huge amount of data stored in relational databases. Since producing RDF data with sufficiently rich semantics is often important in order to make the data usable, interoperable and linkable, there are various strategies developed to enrich data semantics. Turning RDB to RDF has proven to be of value when dealing with SQL databases. It offers a straightforward and practical system for relational database conversion into RDF. RDB2RDF and the Future Moving forward beyond RDB-to-RDF methods, it will become necessary to find a compromise between the expressiveness of RDB to RDF mapping languages and the need for updating relational data using protocols of the semantic web. Creating, updating, and deleting RDF data should only be made possible in a secure, reliable, trustworthy, and scalable way.

When Apple finally released Java 6 for Mac OS 10.5.2, the Java community was more than a little upset. Java 6 only supports 64 Bit on Mac No Cocoa Support What to Do About Java 6 on Mac Using Java on Mac in 2022 What’s Changed Since Java 6 Where is Java on Mac Headed? The history of Java releases on Mac has been more than a little problematic. New updates for Java always find their way to Mac a few years too late and they are often more limited than their Linux and Windows counterparts. Let’s see how Java 6 on Mac stacked up and take a look at the latest Java release for mac and see how it compares. Java 6 on Mac Only Supports 64 Bit This means that Java 6 doesn't run on 1-year-old MacBooks or all early adopters of the Intel switch. A huge amount of people can't run 64-bit. Java 6 on Mac requires much more specific technology than Java 6 did on any of its counterparts. We tend to have a lot of opinions about how to code differently with Java, but we can all agree that Java 6 didn’t really work for Mac. Another problem is that it only supports 64-bit applications, Bye-bye applets in Safari. These are huge setbacks for people who were looking forward to Java on Mac, but the problems didn’t stop here. No Cocoa Support Because of the lack of 64-bit libraries for cocoa, it is not possible to use cocoa with Java 6. Nearly every Java application on Macs uses cocoa to make it look better on Mac OS. Some even are 100% cocoa, like Cyberduck. Because of that, only a small percentage of Java applications can run on Java 6. Java 6 really needed more Mac-specific support in order to function like it did on Windows or Linux. In fact, you have a better chance of performance tuning Java on Linux than you did on a Mac. Apple Knows This Apple is well aware of these problems. The update doesn't make Java 6 the default VM. Apple's preferences dialog even warns you if you want to make it the default VM. Having Apple and Java clash like this only made things more difficult for people working with Java on a Mac. So, What To Do Now? Options were limited for working with Java 6 on Mac. What made Java 6 on Mac even worse was the lack of any good workarounds or alternatives. You either had to commit to a limited system or try something a little involved. These are your options. We only have three choices from here: Switch back to Windows / Linux for Java development Use SoyLatte and help them to create the native GUI pipeline Ask Apple to fix these issues In the long term, no. 2 would be the best. A Java implementation by a large community would have faster release times. We can't wait for Apple to fix these issues—we have to do it ourselves. Getting Java 6 to turn on Mac requires some pretty advanced Java tutorials. Now, let’s take a look at what’s changed since Java 6. Using Java on Mac in 2022 In terms of running Java on Mac, so much has changed since Java 6. In fact, it would be just a few years until the release of Java 7 things completely changed for working with Java and working on an Apple computer. We're going to take a look at some of these specific changes and just see how the landscape of using Java on a Mac has changed from Java 6 all the way to Java 17. Using Java has only gotten more developed as the years have gone by. After all, becoming a Java developer starts with getting Java running on your Mac! What’s Changed Since Java 6 on Mac If you were trying to use Java on Mac since Java 6, you were up against a lot of trouble. You'd have to either settle for a Java that didn't perform nearly as well as it did online up to your PC or go through a bunch of complicated workarounds and still be stuck without all the features. What's important to keep in mind is that Java is more important today than it's ever been. While you might hear some people saying that Java is on the way out, Java still has plenty of use and pops up everything from popular applications, to websites, and it is a highly preferred language for programmers the world over. Java Becomes Mac Native All the DIY fixes in the world couldn't get us ahead for making Java work on Mac. However, things would have quickly changed with the release of Java 7. Starting with Java 7, Java releases work with Apple technology as long as the systems are compatible. You can run compatible editions of Java with your Mac laptop or computer. It all depends on whether or not the specs of your Mac match up with the edition of Java you want to run. Here’s where to start to find some familiar limitations for using Java on a Mac. There are Still Limitations (Java, Intel, and Mac) Even though Java runs on Mac after Java 7, there are still some problems with trying to get Java to run on Apple's technology. If you’re looking for the best toolkits, tips, and tricks for Java, you’re going to need to get it running first! Despite all the advances that are made, you're still going to encounter a few problems with trying to get Java to run on a Mac. The first thing that we have to talk about is that Java is designed to work with the Intel processor versions of Mac. Now that Mac is coming out with their own processor chips, we're seeing compatibility issues with Java and plenty of other technology that people rely on. Apple's desire to keep everything proprietary and stay in a closed sandbox is definitely costing them when it comes to reliably working with some of today's most popular technology. There are also issues when it comes to which Mac operating system you're using. There's a good chance that your Java version might not be compatible with the Mac computer that you're working with depending on the operating system that that Mac runs. Where Things Are Headed for Java on Mac There is good news for the future though. As Apple’s processor technology becomes more popular, more software is going to become compatible. Java is likely to follow suit with Adobe and plenty of others working to find ways to work with Mac’s M1 processors.
