• Pros and Cons of Facebook's React vs. Web Components (Polymer)

  - by CletusW

  What are the main benefits of Facebook's React over the upcoming Web Components spec and vice versa (or perhaps a more apples-to-apples comparison would be to Google's Polymer library)? According to this JSConf EU talk and the React homepage, the main benefits of React are: Decoupling and increased cohesion using a component model Abstraction, Composition and Expressivity Virtual DOM & Synthetic events (which basically means they completely re-implemented the DOM and its event system) Enables modern HTML5 event stuff on IE 8 Server-side rendering Testability Bindings to SVG, VML, and <canvas> Almost everything mentioned is being integrated into browsers natively through Web Components except this virtual DOM concept (obviously). I can see how the virtual DOM and synthetic events can be beneficial today to support old browsers, but isn't throwing away a huge chunk of native browser code kind of like shooting yourself in the foot in the long term? As far as modern browsers are concerned, isn't that a lot of unnecessary overhead/reinventing of the wheel? Here are some things I think React is missing that Web Components will care of. Correct me if I'm wrong. Native browser support (read "guaranteed to be faster") Write script in a scripting language, write styles in a styling language, write markup in a markup language. Style encapsulation using Shadow DOM React instead has this, which requires writing CSS in JavaScript. Not pretty. Two-way binding

• Assuming "clean code/architecture" is there a difference in "effort" between PHP or Java/J2EE web application development?

  - by PhD

  A client asked us to estimate effort when selecting PHP as the implementation language for his next web-based application. We spent about a week exploring PHP, prototyping, testing etc., We are quite new to this language - may have hacked around it in the past but, let's go with PHP-noobs but application development experts (for the lack of a better, less flattering word :) It seems, that if we write, clean maintainable code, follow separation of concerns, enterprise architecture patters (DAOs etc.) the 'effort' in creating an object-oriented PHP based web-application seems to be the same for a Java based one. Here's our equation for estimating the effort (development/delivery time): ConstructionEffort = f(analysis, design, coding, testing, review, deployment) We were specifically comparing effort estimates in creating an enterprise application with the following: PHP + CakePHP/CodeIgniter (should we have considered others?) Java + Spring + Restlet It's an end-to-end application: Client: Javascript/jQuery + HTML/CSS Middle tier/Business Logic - (Still evaluating PHP/Java) Database: MySQL The effort estimates of the 1st and 3rd tier are constant and relatively independent of the middle tier's technology. At a high level with an initial breakdown into user stories of the requested features as well as a high-level SWAG on the sheer number of classes/SLOC that would be required for PHP doesn't seem to differ by much from what is required of the same in Java. Is this correct? We are basing our initial estimates on the initial prototyping/coding we've done with PHP - we are currently disregarding fluency with the language as a factor, since that'll be an initial hurdle and not a long term impediment IMHO (we also have sufficient time to become quite fluent with PHP). I'm interested in knowing the programmers' perspective with respect to effort when creating similar applications with either of the languages to justify choosing one over the other. Are we missing something here? It seems we are going against popular belief of PHP being quicker to market (or we being very fluent with Java have our vision clouded). It doesn't seem to have any coding/programming effort saving from what we/ve played around with.

• Recommend a CMS and extension to build an Event Manager [closed]

  - by Haris

  I posted this question on SO but good friends there told me that SE is the better place for these kind of questions and the post was locked there by community. Hence, posting the question here as well: I have a lead to build an event manager solution in LAMP with following functionality: It should handle events by country, city, locality in city, type of event, venue type etc. following are a few user features: to see details of city, venue, event, performer etc. to purchase tickets and reserve tables. to search for events by city, venue, type, performer etc. to manage favorite venues and performers, save events etc. the venues should be able to add their events I plan to use a CMS (Joomla, Drupal etc.) with some ready made extension that provides most of the functionality or provide framework to build upon. Could you guys suggest me a CMS and an extension to build this. I know it is possible to do this in both Joomla or Drupal. What I am looking is the extension that is closest to my requirements whether it is done in Joomla or Drupal, or as a matter of fact any other CMS. Thanks in anticipation!

• Architecture of a "website generator" web application

  - by Resorath

  What is the most maintainable and efficient way to architect a web application who's purpose is to host and generate websites which can be customized to a certain degree? There are a lot of these style of applications in the wild that generate all kinds of sites, from sites that host World of Warcraft guilds like guildlaunch to other sites like my wedding for wedding site hosting. My question is, what is the basic architecture that these sites operate on? I imagine there are two ways of thinking about this. A central set of code that all sites on the host run against, and it acts differently based on which site was visited. In this manner, when the base code is updated all sites are updated simultaneously. Or, the code for an individual site exists in a silo, and is simply replicated to a new directory each time a site is created. When an update needs to be applied, the code is pushed out to each site silo. In my case, I am working in PHP with the CodeIgniter framework, however the answer need not be limited to this case. Which method (if any) creates a more maintainable and efficient architecture to manage this style of web application?

• How to customize web-app (pages and UI) for different customers

  - by demoncodemonkey

  We have an ASP.NET web-application which has become difficult to maintain, and I'm looking for ideas on how to redesign it. It's an employee administration system which can be highly customized for each of our customers. Let me explain how it works now: On the default page we have a menu where a user can select a task, such as Create Employee or View Timesheet. I'll use Create Employee as an example. When a user selects Create Employee from the menu, an ASPX page is loaded which contains a dynamically loaded usercontrol for the selected menuitem, e.g. for Create Employee this would be AddEmployee.ascx If the user clicks Save on the control, it navigates to the default page. Some menuitems involve multiple steps, so if the user clicks Next on a multi-step flow then it will navigate to the next page in the flow, and so on until it reaches the final step, where clicking Save navigates to the default page. Some customers may require an extra step in the Create Employee flow (e.g. SecurityClearance.ascx) but others may not. Different customers may use the same ASCX usercontrol, so in the AddEmployee.OnInit we can customize the fields for that customer, i.e. making certain fields hidden or readonly or mandatory. The following things are customizable per customer: Menu items Steps in each flow (ascx control names) Hidden fields in each ascx Mandatory fields in each ascx Rules relating to each ascx, which allows certain logic to be used in the code for that customer The customizations are held in a huge XML file per customer, which could be 7500 lines long. Is there any framework or rules-engine that we could use to customize our application in this way? How do other applications manage customizations per customer?

• The 2012 JAX Innovation Awards

  - by Janice J. Heiss

  A new article, now up on otn/java, titled “The 2012 JAX Innovation Awards” reports on  important Java developments celebrated by the Awards, which were announced in July of 2012. The Awards, given by S&S Media Group, aim to, "Reward those technologies, companies, organizations and individuals that make outstanding contributions to Java." The Awards fall into three categories: Most Innovative Java Technology, Most Innovative Java Company, and Top Java Ambassador. In addition, a finalist who did not win an award receives a Special Jury prize, "in acknowledgement of their unique contribution and positive impact on the Java ecosystem."The winners were: JetBrains for Most Innovative Java Company; Adam Bien as Top Java Ambassador; Restructure 101, created by Headway Software, as Most Innovative Technology; and Charles Nutter, Special Jury award. Each winner received a $2,500 prize. The five finalists in each category were invited to attend the JAX Conference in San Francisco, California. This year's winners each received a $2,500 prize. JetBrains Fellow, Ann Oreshnikova, listed her favorite JetBrains innovations: * Nullability annotations and nullability checker* CamelCase navigation and completion* Continuous Integration in grid (on multiple agents), in TeamCity* IntelliJ Platform and its language support framework* MPS language workbench* Kotlin programming languageWhen asked what currently excites him about Java, Adam Bien, winner of the Java Ambassador Award, expressed enthusiasm over the increasing interest of smaller companies and startups for Java EE. “This is a very good sign,” he said. “Only a few years ago J2EE was mostly used by larger companies -- now it becomes interesting even for one-person shows. Enterprise Java events are also extremely popular. On the Java SE side, I'm really excited about Project Nashorn.”Special Jury Prize Winner, Charles Nutter of Red Hat, remarked that, “JRuby seems to have hit a tipping point this past year, moving from ‘just another Ruby implementation’ to ‘the best Ruby implementation for X,’ where X may be performance, scaling, big data, stability, reliability, security, and a number of other features important for today's applications.

• Quickly ubuntu-application + indicator template don't work

• Extremely simple online multiplayer game

  - by Postscripter

  I am considering creating a simple multiplayer game, which focuses on physics and can accommodate up to 30 players per session. Very simple graphics, but smart physics (pushing, weight and gravity, balance) is required. After some research I found a good java script (framework ??) called box2d.js I found the demo to be excellent. this is is kind of physics am looking for in my game. Now, what other frameworks will I need? Node.js?? Prototype.js?? (btw, I found the latest versoin of protoype.js to be released in 2010...?? is this still supported? Should I avoid using it?) What bout HTML 5 and Canvas? would I need them? websockets? Am a beginner in web programming + game programming world. but I will learn fast, am computer science graduate. (but no much web expeience but know essentionals javascript, html, css..). I just need a guiding path to build my game. Thanks

• XNA on the TechNet Wiki

  - by Michael B. McLaughlin

  Many months ago I came across an interesting Microsoft website, the TechNet Wiki, when I was looking for information about something that I can’t even remember anymore. I noticed at the time that its section on gaming technologies was sparse and even exchanged a few emails with one of the friendly Microsoft employees who contributes there regularly about some ideas I had for the site. I seem to recall mentioning my intentions to add some articles on XNA when I found the time but between one thing and another it seemed like I was busy from the end of last Summer straight through ‘til now. Yesterday I came across the TechNet Wiki link in my miscellaneous links collection and remembered my intentions many months ago. I decided that adding XNA pages to it would make a nice project to work on while taking breaks from my other projects. So I wrote my first two articles for it: XNA Framework Overview and Content Pipeline Overview. I hope to add more in the coming days and weeks. I’d be delighted if some of my fellow XNA enthusiasts out there joined in, time permitting. Anyone else who’d like to add a page or two on a topic area you’re familiar with, this seems like a great opportunity to contribute to the community and help build a nice knowledge base to benefit all of us who are always interested in learning something new!

• Antenna Aligner part 1: In the beginning.

  - by Chris George

  Picture the scene, it's 9pm, I'm in my caravan (yes I know, I've heard all the jokes!) with my family and I'm trying to tune the tv by moving the aerial, retuning, moving the aerial again, retuning... 45 mins and much cursing later I succeed. Surely there must be an easier way than this? Aha, an app; there must be an app for that? So I search in the AppStore for such an app, but curiously drew a blank. Then the seeds of the idea started to grow. I can code, I work in a software house with lots of very clever people, surely I can make an app that points to the nearest digital tv transmitter! Not having looked into app development before, I investigated how one goes about making an iPhone app and was quickly greeted by a now familiar answer "Buy a mac!". That was not an option for many reasons, mostly wife related! My dreams were starting to fade until one of my colleagues pointed out that within Red Gate, the very company I work for, there was on-going development on a piece of software that would allow me to write an app using Visual Studio on a Windows machine, Nomad! Once I signed up for the beta program I got to work learning the Jquery mobile / Phonegap framework. Within a couple of hours I had written (in Visual Studio), built in the cloud (using Nomad) and published (via TestFlight) my first iPhone app onto my iPhone ! It didn't do much, but it was a step in the right direction. To be continued...

• What is the best way for an experienced developer to work on a WordPress blog

  - by nanothief

  I'm beginning to work on my first WordPress blog, however I've noticed most tutorials just have you do modifications (such as theme changes, installing plugins) on the production site. This worries me for a few reasons: No backups No version control If you make a mistake, your production site is affected Developing remotely is slower than local development, especially when tweaking css files. I understand why WordPress works like this - it allows people with no development experience to manage their WordPress installation (or the one provided by their service provider). It also allows you to work on the WordPress installation without having ssh access to the server. However as I am confortable working with tools like git and ssh, and am using a virtual server for the blog, this isn't very important to me. So I was wondering what techniques experienced developers use when working on a WordPress blog. For example: Do you develop locally, then push the changes to the live site? How do you do this? How do you manage database changes and backups? What do you store under version control (if anything)? If a plugin changes the database, do you somehow track the changes it does in version control, so you can rollback the changes done by the plugin if you need to? Or maybe I'm just overcomplicating everything if working on the production site isn't as risky as I am thinking it would be. I would appreciate any answers either way.

• How to handle sorting of complex objects?

  - by AedonEtLIRA

  How would one sort a list of objects that have more than one sortable element? Suppose you have a simple object Car and car is a defined as such: class Car { public String make; public String model; public int year; public String color; // ... No methods, just a structure / container } I designed a simple framework that would allow for multiple SortOptions to be provided to a Sorter that would then sort the list. interface ISorter<T> { List<T> sort(List<T> items); void addSortOption(ISortOption<T> option); ISortOption<T>[] getSortOptions(); void setSortOption(ISortOption<T> option); } interface ISortOption<T> { String getLabel(); int compare(T t1, T t2); } Example use class SimpleStringSorter extends MergeSorter<String> { { addSorter(new AlphaSorter()); } private static final class AlphaSorter implements ISortOption<String> { // ... implementation of alpha compare and get label } } The issue with this solution is that it is not easily expandable. If car was to ever receive a new field, say, currentOwner. I would need to add the field, then track down the sorter class file, implement a new sort option class then recompile the application for redistribution. Is there an easier more expandable/practical way to sort data like this?

• What technical details should a programmer of a web application consider before making the site public?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web application consider before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also, I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification.

• Bending of track in a racing game

  - by caius

  I am trying to create a small racing game in which the track would be modeled using a BSpline curve for the path's center line and directional vectors to define the 'bending' of the track at each point. My problem is that I don't know how to calculate the correct bending / slope of the curve, in such a way that it would be optimal or at least visually nice for a car to 'bend in the corner'. My idea was to use the direction of the 2nd derivatives of the curve, however while this approach looks fine for most of the track, there are points in which the 2nd derivative makes sharp 'twists' / very quick 180 degree flips. I also read about 'knots' of bsplines, but I don't know if such 'twist' in 2nd derivatives is a knot or knots are something else. Can you tell me that using a BSpline: 1. How could I calculate a visually nice bending of a track for a racing game? 2. Is it possible to do this by using some simple calculations of centripertal force / gravity? 3. Is it possible to do this by using 1st, 2nd and 3rd derivatives of the BSpline curve? I am not looking for the 'physically correct' bending angle for the track, I would just like to create something which is visually pleasing in a simple game. I am using a framework which has a built-in class for BSpline, including support for 1st, 2nd and 3rd derivatives of the curve.

• Should Developers Perform All Tasks or Should They Specialize?

  - by Bob Horn

  Disclaimer: The intent of this question isn't to discern what is better for the individual developer, but for the system as a whole. I've worked in environments where small teams managed certain areas. For example, there would be a small team for every one of these functions: UI Framework code Business/application logic Database I've also worked on teams where the developers were responsible for all of these areas and more (QA, analsyt, etc...). My current environment promotes agile development (specifically scrum) and everyone has their hands in every area mentioned above. While there are pros and cons to each approach, I'd be curious to know if there are more pros and cons than I list below, and also what the generally feeling is about which approach is better. Devs Do It All Pros 1. Developers may be more well-rounded 2. Developers know more of the system Cons 1. Everyone has their hands in all areas, increasing the probability of creating less-than-optimal results in that area 2. It can take longer to do something with which you are unfamiliar (jack of all trades, master of none) Devs Specialize Pros 1. Developers can create policies and procedures for their area of expertise and more easily enforce them 2. Developers have more of a chance to become deeply knowledgeable about their specific area and make it the best it can be 3. Other developers don't cross boundaries and degrade another area Cons 1. As one colleague put it: "Why would you want to pigeon-hole yourself like that?" (Meaning some developers won't get a chance to work in certain areas.) It's easy to say how wonderful agile is, and that we should do it all, but I'm somewhat of a fan of having areas of expertise. Without that expertise, I've seen code degrade, database schemas become difficult to manage, hack UI code, etc... Let's face it, some people make careers out of doing just UI work, or just database work. It's not that easy to just fill in and do as good of a job as an expert in that area.

• Triggering Data Changes in N-Tier

  - by Ryan Kinal

  I've been studying n-tier architectures as of late, particularly in VB.NET with Entity Framework and/or LINQ to SQL. I understand the basic concepts, but have been wondering about best practices in regard to triggering CRUD-type operations from user input/action. So, the arcitecture looks something like the following: [presentation layer] - [business layer] - [data layer] - (database) Getting information from the database into the presentation layer is simple and abstracted. It's just a matter of instantiating a new object from the business layer, which in turn uses the data layer to get at the correct information. However, saving (updating and inserting), and deleting seem to require particular APIs on the relevant business objects. I have to assume this is standard practice, unless a business object will save itself on various operations (which seems inefficient), or on disposal (which seems like it just wouldn't work, or may be unwieldy and unreliable). Should my "savable" business objects all implement a particular "ISavable" or "IDatabaseObject" interface? Is this a recognized (anti-)pattern? Are there other, better patterns I should be using that I'm just unaware of? The TLDR question, I suppose, is How does the presentation layer trigger database changes?

• How can I learn more about ADF?

  - by jhpierce -Oracle

  Look to the Oracle Technology Network for a wealth of information, tutorials, best practices and coding examples. The place to start is the Oracle Application Development Framework (ADF) web page. The Oracle ADF page has basic information and downloads for ADF, but the real wealth is in the links to other pages. One of the pages is the Oracle ADF Code Corner,  which is a blog-style column that provides hints, tips and coding examples for ADF developers. The content on this page ranges from easy to complex and often contains advanced programming concepts. The content is inspired by questions asked on the Oracle JDeveloper customer forum on OTN. The ADF Code Corner has many articles that will inspire your imagination and possibly solve your coding problem.How about the Oracle ADF Architecture Square link? The Oracle ADF Architecture Square focuses on architectural issues and developer guidelines for writing ADF software solutions. The goal is to give ADF developers an understanding of the necessary decisions for building a successful ADF application, to offer potential architectural blueprints to choose from when putting the ADF application together, and to provide potential ADF best practices to take back to your development team. The Oracle ADF Mobile link gives information on developing mobile applications for iOS and Android based applications. There are links to ADF Mobile Overview, ADF Mobile demos and ADF Mobile courses.The Sample ADF Applications link lists sample applications and other resources where you can find code samples for ADF. These are complete ADF applications that can be downloaded into JDeveloper and give you insight into coding an application.There are many more links found under the "Learn More" tab that can equip the developer with the knowledge they need to develop their applications. There are links to overview papers, technical resources, related topics and available training. The information you need IS just a click away.

• Need help with ColdFusion and ASP.NET site [closed]

  - by Michael Stone

  To begin, I wasn't too sure how to title this.. I've got a few questions. First off, I've got a very big site that's in ColdFusion and we've been migrating to ASP.NET C# 4.0 the last 8 months. I've got a team of 7 programmers and no one can seem to figure out these answers, not even our senior C# programmer. We're using Team Foundation Server and we can't figure out how to only push up one small change at time. Right now we're stuck to publishing the entire site and it's causing serious issues. We've currently got the site as a Project and not a Website. We're wondering if that's one issue. I actually think it might be a problem. We're also dealing with an issue where we can't access our regular folders with relative paths. So we're first developing our admin side in .NET and We've got our regular site and then we've got another site within that for our .NET admin tools. By site, I'm referring to them actually being Sites in IIS. This also creates a problem for us when we're creating tools that upload images and want to store them and access them from our parent Site. I'd very much appreciate any advice on how to go about this in the most standardized way. So what I'm hoping for is advise on: -Publishing and managing a site/project in Team Foundation Server. Being able to push up one fix at a time if needed would be GREAT! -Any help figuring out the issuing referencing folders from my .NET child site to my parent ColdFusion site using regular relative paths. "/a/images/b/" would be nice nice instead of only being able to do "/b/images/" We're using ColdFusion 8, C# Asp.NET 4.0/Entity Framework/POCO Templates, and a Windows 2008 R2 Server. Thank you in advance for any help.

• Places to store basic data

  - by Ella

  I am using PHP. I'm building a fully modular CMS, which is destined for the public. Some people might view this as a framework, but I intend to write a set of extensions for it, extensions that will make it a CMS :P Because it's completely modular I have a problem figuring out how to load extensions. Practically I need to get the list of active extensions, so I can load them inside my base class. I load them by reading some file headers, which contain a "dependency" field. That field decides the order in which I have to instantiate the objects. The problem is that when the CMS starts I have no database interface, because that's an extension too, so I can't store the active extensions list in the database :) You might ask how are extensions activated in the first place. Well - in the administration interface, which is an extension as well (obviously on first install of the CMS there will be some extensions active by default). Could writing that list inside a text file be a solution? The problem is that a lot of hosts are not very nice with scripts when they write files. And since this CMS is public I might have a problem here?

• Is Wordpress more appropriate than Magento/Opencart for site like this?

  - by Alex

  The premise of the site is that a user pays a small fee to advertise an item that they want to sell. Therefore the user is responsible for adding the "products", not the administrator. The product upload will create a product page for that item. This is a rather common framework that I'm sure you're familiar with. My initial thought was that it would be best suited using Magento - mainly because it needs to accept payments - and the products will grow to form a catalog of categorized products. However - there is no concept of a shopping cart. A buyer does not buy the item online, or go to a checkout. They simply look at the product, and contact the seller if they like it. The buyer and seller then take it from there. For this reason, I then begin to suspect that Magento is perhaps too overkill, or just simply not the right CMS if there is on checkout procedure (other than the uploader making a payment) So then I begin to think Wordpress....Hmmm Feature requirements: User's can add content via a form process User's can be directed to a payment gateway For each product listing - a series of photographs shall be displayed, in thumbnail form Zoom capabilities/rotate on the images would be a welcome feature In short - e-commerce CMS, or something more simple?

• What would be a good topic for research on "edge of multiple processors / computers programming" topic?

  - by Kabumbus

  This is a subjective discussion so we can express our dreams and hopes here. A "topic" must be like a task with point to have as end result a software poduct. A "topic" must be mainly about "Software engineering", "Algorithm and data structure concepts" and perhaps "Design patterns". I mean let us try to look what is not already there? What can be developed in fiew month and give a breakthrue / start a new leap / show somethig not realized before in science of f multiple computers programming? What i see is already there: LAN / wire and other infrastractural programms for connecting on device level MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging on top Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

• Should I care about Junit redundancy when using setUp() with @Before annotation?

  - by c_maker

  Even though developers have switched from junit 3.x to 4.x I still see the following 99% of the time: @Before public void setUp(){/*some setup code*/} @After public void tearDown(){/*some clean up code*/} Just to clarify my point... in Junit 4.x, when the runners are set up correctly, the framework will pick up the @Before and @After annotations no matter the method name. So why do developers keep using the same conventional junit 3.x names? Is there any harm keeping the old names while also using the annotations (other than it makes me feel like devs do not know how this really works and just in case, use the same name AND annotate as well)? Is there any harm in changing the names to something maybe more meaningful, like eachTestMethod() (which looks great with @Before since it reads 'before each test method') or initializeEachTestMethod()? What do you do and why? I know this is a tiny thing (and may probably be even unimportant to some), but it is always in the back of my mind when I write a test and see this. I want to either follow this pattern or not but I want to know why I am doing it and not just because 99% of my fellow developers do it as well.
