• Customizing The Fusion Applications Simplified UI (aka FUSE)

  - by Richard Bingham

  Everyone who has seen it is impressed by the new Simplified UI, providing self-service workers the ease-of-use that they expect from a modern web application. As always, people want and need to make small adjustments, especially in the Cloud, and thankfully even in its first release there is good support for this. The main features are: Configuring the branding and look-and-feel (known as a theme) of the Simplified UI. Adding you own custom announcements to the Simplified UI homepage. Using Page Composer to edit component properties, such as re-label text or hiding unwanted fields. Using MDS Sandboxes to manage groups of related customizations. Using Application Composer to adjust the fields available in certain Simplified UI pages. These are demonstrated in the video embedded below, available as part of our YouTube channel, as well as being documented in the extensibility guide. &amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;quot;&amp;amp;amp;amp;gt;&amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;gt; As mentioned, this is the first release of this capability so if there is something you're stuck on please use our forum and we'll try to help, or if you have a requirement for a new Simplified UI customization, please add a comment below.

• How to enable a Web portal-based rich enterprise platform on different domains and hosts using JS without customization/ server configuration

  - by S.Jalali

  Our company Coscend has built a Web portal-based communications and cloud collaboration platform by using JavaScript (JS), which is embedded in HTML5 and formatted with CSS3. Other technologies used in the core code include Flash, Flex, PostgreSQL and MySQL. Our team would like to host this platform on five different Windows and Linux environments that run different types of Web servers such as IIS and Apache. Technical challenge: Each of these Windows and Linux servers have a different host name and domain name (and IP address), but we would like to keep our enterprise platform independent of host server configuration. Possible approach to solution: We think an API (interface module with a GUI) is needed to accomplish this level of modularity and flexibility while deploying at our enterprise customers. Seeking your insights: In this context, our team would appreciate your guidance on: Is there an algorithmic method to implement this Web portal-based platform in these Windows and Linux environments while separating it from server configuration, i.e., customizing the host name, domain name and IP address for each individual instance? For example, would it be suitable to create some JS variables / objects for host name and domain name and call them in the different implementations? If a reference to the host/domain names occurs on hundreds of portal modules, these variables or JS objects would replace that. If so, what is the best way to make these object modules written in JS portable and re-usable across different environments and instances for enterprise customers? Here is an example of the implemented code for the said platform. The following Web site (www.CoscendCommunications.com) was built using this enterprise collaboration platform and has the base code examples of the platform. This Web site is domain-specific. We like to make the underlying platform such that it is domain and host-independent. This will allow the underlying platform to be deployed in multiple instances of our enterprise customers.

• Is the Entity Component System architecture object oriented by definition?

  - by tieTYT

  Is the Entity Component System architecture object oriented, by definition? It seems more procedural or functional to me. My opinion is that it doesn't prevent you from implementing it in an OO language, but it would not be idiomatic to do so in a staunchly OO way. It seems like ECS separates data (E & C) from behavior (S). As evidence: The idea is to have no game methods embedded in the entity. And: The component consists of a minimal set of data needed for a specific purpose Systems are single purpose functions that take a set of entities which have a specific component I think this is not object oriented because a big part of being object oriented is combining your data and behavior together. As evidence: In contrast, the object-oriented approach encourages the programmer to place data where it is not directly accessible by the rest of the program. Instead, the data is accessed by calling specially written functions, commonly called methods, which are bundled in with the data. ECS, on the other hand, seems to be all about separating your data from your behavior.

• How to print a pdf in a new tab? [migrated]

  - by TheDuke777

  I need to print a pdf by opening it in a new window. I've looked at tutorials for days, but nothing is working. I've tried many approaches, but this is the most recent: <!DOCTYPE html> <html> <head> <script type="text/javascript"> function print() { window.getElementById("pdf").focus(); window.getElementById("pdf").print(); } </script> </head> <body onload="print()"> <embed id="pdf" src="http://path/to/file" /> </body> </html> The page loads fine, with the pdf embedded. But it won't print, and I feel like I've been beating my head against a brick wall trying to figure this out. How can I get this to work? I'm willing to try anything at this point.

• Proper XAML for Windows 8 Applications [closed]

  - by Jaapjan

  Traditionally, my programs do their work in the background and when I do have to make an interface for some reason, they often do not need to be complex which means I can use a simple Windows Forms or console application. But lets be honest-- Windows Forms? That is so ... ancient! Instead I have been looking at Windows 8. A new interface, different, maybe better-- but fun to give a try. Which means XAML. Now, XAML isn't all that hard in concept. Panel here, button there-- A smattering of XML. My question in short: Where can I find resources that teach me how to write good XAML code for Windows 8 applications? The long version: How do I combine XAML constructs to achieve effects? Horizontal panels with multiple sections you can scroll through with your finger, the proper way? How should you use default style resources Windows 8 might give you by default? How do I properly create a panel with user info on the right? Left aligned stackpanels with embedded dockpanels? Yes? No? Why?

• How well do graduates from top universities perform and how does it feel compare to the rest of the world?

  - by Amumu

  I always have impressions to those who got admitted into top Universities like MIT, Standford... for studying Engineering. I don't actually know what they are doing in the University or what they will do, but I always feel they can perform higher level tasks with more complexities. I always think that they are good at create and applying mathematical model in real life and I tend to agree: If you can't apply math, it's your problems, not math. I am a junior software engineer on embedded devices. I am learning more on Linux kernel and low level stuffs. Even so, my will is not strong enough to pursue technical path forever, with a final purpose is to create something significant on my own. May I have a chance to get on their level if I keep learning through experience and self-study? In my opinion, Math is the must have requirement, since it seems that programs on those Universities are very Math oriented. Without very strong math skill, how can one perform good in science and researching beyond making regular business products?

• JavaOne 2012 in Review

  - by Janice J. Heiss

  Noted freelance writer Steve Meloan has a new article up on otn/java, titled, “JavaOne 2012 Review: Make the Future Java” in which he summarizes the happenings at JavaOne 2012. Along the way, he reminds us that if the future turns out to be anything like the past, Java will do fine: The repeated theme for this year's conference was ‘Make the Future Java,’ and according to recent stats, the groundwork is already firmly in place:    There are 9 million Java developers worldwide.    Three billion devices run Java.    Five billion Java Cards are in use.    One hundred percent of Blu-ray Disc players ship with Java.    Ninety-seven percent of enterprise desktops run Java.    Eighty-nine percent of PC desktops run Java.This year's content curriculum program was organized under seven technical tracks:    Core Java Platform    Development Tools and Techniques    Emerging Languages on the JVM    Enterprise Service Architectures and the Cloud    Java EE Web Profile and Platform Technologies    Java ME, Java Card, Embedded, and Devices    JavaFX and Rich User Experiences”Meloan artfully reminds us of how JavaOne makes learning fun. Have a look at the article here.

• Learning curve for web development

  - by refro

  At the moment our team has a huge challenge, we're being asked to deliver a new GUI for an embedded controller. The deadline is very tight and is set on April 2013. Our team is very diverse, some people are on the level of functional programming (mostly C), others (including myself) have mastered object oriented programming (C++, C#). We built a prototype for Android, although it has its quirks, it is mostly just OO. For the future there is a wish to support multiple platforms (Windows, Android, iOS). In my opinion a HTML5 app with a native app shell is the way to go. When gathering more information on the frameworks to use etc., it became obvious to me a paradigm shift is needed. None of us have a web background so we need to learn from the ground up. The shift from functional to OO took us about 6 months to become productive (and some of the early subsystems were rewritten because they were a total mess). Can we expect the learning curve to be similar? Can this be pulled off with a web app? (My feeling says it will already be hard to pull off as a native app which is at the edge of our comfort zone).

• Is there such thing like a "refactoring/maintainability group" role in software companies?

  - by dukeofgaming

  So, I work in a company that does embedded software development, other groups focus in the core development of different products' software and my department (which is in another geographical location) which is located at the factory has to deal with software development as well, but across all products, so that we can also fix things quicker when the lines go down due to software problems with the product. In other words, we are generalists while other groups specialize on each product. Thing is, it is kind of hard to get involved in core development when you are distributed geographically (well, I know it really isn't that hard, but there might be unintended cultural/political barriers when it comes to the discipline of collaborating remotely). So I figured that, since we are currently just putting fires out and somewhat being idle/sub-utilized (even though we are a new department, or maybe that is the reason), I thought that a good role for us could be detecting areas of opportunity of refactoring and rearchitecting code and all other implementations that might have to do with stewarding maintainability and modularity. Other groups aren't focused on this because they don't have the time and they have aggressive deadlines, which damage the quality of the code (eternal story of software projects) The thing is that I want my group/department to be recognized by management and other groups with this role officially, and I'm having trouble to come up with a good definition/identity of our group for this matter. So my question is: is this role something that already exists?, or am I the first one to make something like this up?

• From the Coalface - 3 - Work as hard as you can to be as lazy as you can!

  - by TATWORTH

  The saga of the Change Log A recent conversation reminded me of the need for change logs within a database, to record when various change scripts were run. Creating such the required table is simple. A typical table for this consists of: Id - identity Integer primary key ChangeFileName - NVARCHAR(128) to hold the name of the file run. DateAdded - DateTime non-null with default value of getutcdate() Purpose - NVARCHAR(128) Rerunnable - Bit non-null default 0. By good design of the table only two data values normally need to be supplied. Two stored procedures, one for inserting data and one to list in reverse sequence the log complete the database essentials. The complete implementation can be found in the CommonData solution at http://CommonData.CodePlex.Com By including a call the add Change Log stored procedure, each script can log its name and purpose for posterity. The scripts that were applied to say the UAT system and their sequence of application can be readily identified for running on the Live system. Formatting XML XML is often produced as one continous string with no embedded CR/LF. To get it into human readable form, open it in visual studio, swap to another tab and back and click the format document button. The XML will then be nicely formatted!

• How can one find software development work that involves directly the final end user?

  - by RJa

  I've worked in software development for 15 years and, while there have been signficant personal achievements and a lot of experience, I've always felt detached from the man/woman-on-the-street, the every day person, how it affects their lives, in a number of ways: the technologies: embedded software, hidden away, stuff not seen by the everyday person. Or process technology supporting manufactured products the size of the systems, meaning many jobs, divided up, work is abstract, not one person can see the whole picture the organisations: large, with departments dealing with different areas, the software, the hardware, the marketing, the sales, the customer support the locations and hours: out-of-town business parks away from the rest of society, fixed locations, inflexible: 9-5 everyday This to me seems typical of the companies I worked for and see elsewhere. Granted, there are positives such as the technology itself and usually being among high calibre co-workers, but the above points frustrate me about the industry because they detach the work from its meaning. How can one: change these things in an existing job, or compensate for them? find other work that avoids these and connects with the final end user? Job designs tend to focus on the job content and technical requirements rather than how the job aims to fulfil end user needs, is meaningful.

• Enemy collision detection with movie clips

  - by user18080

  I have created multiple movieclips with animations within them. It is an obstacle avoidance game and I cannot seem to be able to get my enemies to contact my playableCharacter. The enemies I have created are each embedded on certain levels of my game. I have created an array, enemiesArray to have each of my enemies placed within it. Here is the code for that: //step 1: make sure array exists if(enemiesArray!=null && enemiesArray.length!=0) { //step 2: check all enemies against villain for(var i:int = 0;i < enemiesArray.length; i++) { //step 3: check for collision if(villain.hitTestObject(enemiesArray[i])) { //step 4: do stuff trace("HIT!"); removeChild(enemiesArray[i]); enemiesArray.splice(i,1); removeChild(villain); villain = null; } } } What I am unsure of is whether or not my enemiesArray is actually holding the movieclips I have suggested. If it was, this code would be tracing back a "HIT" for every time I ran into an enemy and would kill my character. It is not doing that however. I am thinking I have to push my movieclips into my array but I don't know how to do that or where for that matter. Any and all help would be much appreciated.

• Tomcat 7 vs. ehCache Standalone Server (Glassfish) Configuration with RESTful Web Services

  - by socal_javaguy

  My requirements consist of using ehCache to send and store data via RESTful web service calls. The data can be stored in-memory or via the filesystem... Never used ehCache before so I am having some issues deciding on which bundle to use. Have downloaded the following bundles: ehcache-2.6.2 ehcache-standalone-server-1.0.0 (1) What is the difference between the two? It seems the ehcache-2.6.2 contains src and binaries, which essentially enables one to bundle it with their webapps (by putting the compiled jar or binaries inside the webapp's WEB-INF/lib folder). But it doesn't seem that it has support for Restful web services. Whereas, ehcache-standalone-server-1.0.0 (comes with an embedded Glassfish server and has support for REST & SOAP) can be used to run as a standalone server. If I my answers to my own question are correct, then that means, I should just use the standalone server? (2) My requirements are to setup ehCache (with REST support) on Tomcat 7. So, how could I setup ehCache on Tomcat 7 as a separate app with REST & SOAP support? Thank you for taking the time to read this...

• How do I develop database-utilizing application in an agile/test-driven-development way?

  - by user39019

  I want to add databases (traditional client/server RDBMS's like Mysql/Postgresql as opposed to NoSQL, or embedded databases) to my toolbox as a developer. I've been using SQLite for simpler projects with only 1 client, but now I want to do more complicated things (ie, db-backed web development). I usually like following agile and/or test-driven-development principles. I generally code in Perl or Python. Questions: How do I test my code such that each run of the test suite starts with a 'pristine' state? Do I run a separate instance of the database server every test? Do I use a temporary database? How do I design my tables/schema so that it is flexible with respect to changing requirements? Do I start with an ORM for my language? Or do I stick to manually coding SQL? One thing I don't find appealing is having to change more than one thing (say, the CREATE TABLE statement and associated crud statements) for one change, b/c that's error prone. On the other hand, I expect ORM's to be a low slower and harder to debug than raw SQL. What is the general strategy for migrating data between one version of the program and a newer one? Do I carefully write ALTER TABLE statements between each version, or do I dump the data and import fresh in the new version?

• "bug" in C++11 text by Stroustrup?

  - by Astara

  I found an apparent contradiction in the c++ text having to do with the result of the c_str() function operating on std:strings (in my copy, the definition and contradiction are on p1040). First it defines the c_str() function as something that produces a 'C-style' (zero-terminated) string, but later it talks about how a C++ c_str value can have embed a 'C'-style, end-of-string terminators (i.e. NUL's) embedded in the string (that is defined by being NUL terminated). Um... does anyone else feel that this is a 'stretching' of the definition of a C-string beyond it's definition? I.e. I think what it means, is that if you were to look at the length() function as applied to the string, it will show a different end of string than using the C-definition of a z-string -- one that can contain any character except NUL, and is terminated by NUL. I likely don't have to worry about it in my of my programs, but it seems like a subtle distinction that makes a C++ c_str, not really a 'C'-string. Am I misunderstanding this issue? Thanks!

• Managing TFS Workspaces

  - by Enrique Lima

  You are the administrator (or since you may be the one that knows the most about it) and you need to do some cleanup on what is connected and perhaps even cleanup after people that have left the organization and left some code checked out in their workspace. What permissions do I need? You will need to have Administer Workspaces permission to perform the following tasks. The commands. In order to execute the commands, you will need to open a Visual Studio Command Prompt, once there you will be able to use the tf command.  This has a nice set of options, which I will be providing a listing for later on in another post. To list all workspaces registered: tf workspaces /collection:<url to your TPC> <workspace>;<owner> To delete a specific workspace: tf workspace /delete /server:<url to your TPC> <workspace>;<owner> If for any reason a workspace has embedded spaces, then surround that with “” (double quotes).

• Enjoy Cloud Odyssey The Oracle Movie

  - by Naresh Persaud

  If you attended Open World you may have seen the promotions for a new movie produced by Oracle. The movie is called Cloud Odyssey and it chronicles the journey of a hero to the cloud. The movie is an animated sci-fi adventure. This movie will be played at Oracle events around the world so you may soon get an invite to attend. Interesting approach to telling the cloud story. For many IT organizations, the journey to the cloud is a major initiative for end users. I am sure Homer would be proud. In fact perhaps if it is successful, I am hopeful we may see a cloud Iliad.  Below, I have embedded a trailer to the movie for your viewing pleasure. While it clearly is not the next Iron Man, it is intriguing. Hope you enjoy.  &amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;gt;

• Web-Service: How much would you charge? [closed]

  - by jacksbox

  I´ve to make an offer to a client who wants me to develope a web-service for him. I have some trouble calculating the pricing - can you help me? Here is a rough outline of the project: It´s a portal on which various artists and entertainers can register and administrate there profile (texts, gallerie, some embedded videos, choose categories and radius of offer, etc). Other user can browse the artists by 3-4 level categories and countries/staats. If someone wants to hire a artists, he can put them in an "shopping-basket" and can mail everyone in his basket. The Artists can answer them with a form on the website (he doesn't get the email of the other person). Users should be able to comment/rate the artists. But if an artists wants this comments/ratings visible on his profile he must pay, and after that, the admin of the site must activate this comments/ratings. So, no more information given, what would you charge (ca.)? Edit: It´ll be developed with php/codeigniter. A .psd design is already there.

• Live HTML Preview

  - by netbeanstips

  When you need to edit an HTML document in NetBeans you may find useful this little plugin that adds a Preview tab to HTML editor window. The plugin works with some small issues in NetBeans 7.4 but I recommend using development builds instead. So install the plugin, restart NetBeans and open any HTML document. Notice there's a Preview button in editor's toolbar (see the red rectangle in the picture below). Now split the editor window by dragging the split button at top right corner. You can also use menu View - Split - Vertically.  Then in the bottom split part toggle Preview button. You will get a live preview of your HTML source code. The preview pane will auto-refresh as you edit the HTML code. There are even some handy tools in Preview toolbar, for example you can resize the preview browser to match the screen dimensions of various device types. I know there is full-blown HTML5 support in NetBeans 7.4. But if you need to edit a single document or when you're running Java-only NetBeans distribution this plugin may come handy... Note: The plugin is built on top of embedded WebKit browser which is based on JavaFX WebView component. So there might be some issue when using the plugin on some flavors of Linux.

• Dynamic Type to do away with Reflection

  The dynamic type in C# 4.0 is a welcome addition to the language. One thing Ive been doing a lot with it is to remove explicit Reflection code thats often necessary when you dynamically need to walk and object hierarchy. In the past Ive had a number of ReflectionUtils that used string based expressions to walk an object hierarchy. With the introduction of dynamic much of the ReflectionUtils code can be removed for cleaner code that runs considerably faster to boot. The old Way - Reflection Heres...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• OpenGL or OpenGL ES

  - by zxspectrum

  What should I learn? OpenGL 4.1 or OpenGL ES 2.0? I will be developing desktop applications using Qt but I may start developing mobile applications in a few months, too. I don't know anything about 3D, 3D math, etc and I'd rather spend 100 bucks in a good book than 1 week digging websites and going through trial and error. One problem I see with OpenGL 4.1 is as far as I know there is no book yet (the most recent ones are for OpenGL 3.3 or 4.0), while there are books on OpenGL ES 2.0. On the other hand, from my naive point of view, OpenGL 4.1 seems like OpenGL ES 2.0 + additions, so it looks like it would be easier/better to first learn OpenGL ES 2.0, then go for the shader language, etc Please, don't tell me to use NeHe (it's generally agreed it's full of bad/old practices), the Durian tutorial, etc. Thanks
