  • rails + sheevaplug = rails home development server and more

    - by microspino
    Hello I'd like to build a "Rails Brick" using a Sheevaplug from Marvell (O.S. is Ubuntu out of the box but You can install other distributions on It). It will be a home server and a silent, low cost (99$) low energy development machine. I'd like to add rails RVM, lot of gems, git-based heroku like deployment, passenger + nginx. This way I could have a portable server with a complete development environment and maybe I could find a hosting company where I can co-locate a grid of this devices or I can sell It as a simple little server for 10 or less users offices, with some centralized rails services (I think to a CMS, a BLOG, a WIKI, calendar or whatever this little jewel could afford). The usb port could make It a print server too or a UMTS link to the web via HUAWEI like usb UMTS keys. Can you give me some hint about: Is this project a crazy-close-to-failure idea? Why? which gem would You include? which rails open source app would you suggest? I have already an Excito Bubba Server at home, I saw the TonidoPlug so It came up in my mind to build something similiar but Rails based (Bubba is PHP based, TonidoPlug I don't know but It does not seems a Rails thing).

  • Beginning 3.2+ iPhone development

    - by Dinah
    I'm interested in learning Objective C for iPhone development. This is a topic which I realize has been covered to death. The qualifying difference is: I'd like to start learning beginning with the latest version (the most recent iPhone OS as of May, 2010 is ver. 3.2 and 4 beta is also out). I'd like to not have to wade through or unlearn legacy information. Using the links I've found throughout related topics on Stack Overflow, I'll read a blog post or tutorial which will say one thing, but then the comments will say, "this is different now in version xyz." For example, I've found this a few times regarding memory management/garbage collection. I assume that Apple's "getting started" doc.s will have the most recent info but many SO posts have said that those are not the most clear. The Stanford iPhone course looks great, but how do I know if it still applies to the most recent versions? Where should one start learning Objective C for iPhone development starting with version 3.2 or later without having as much exposure to legacy information?

  • JPA behaviour...

    - by Marcel
    Hi I have some trouble understanding a JPA behaviour. Mabye someone could give me a hint. Situation: Product entity: @Entity public class Product implements Serializable { ... @OneToMany(mappedBy="product", fetch=FetchType.EAGER) private List<ProductResource> productResources = new ArrayList<ProductResource>(); .... public List<ProductResource> getProductResources() { return productResources; } public boolean equals(Object obj) { if (obj == this) return true; if (obj == null) return false; if (!(obj instanceof Product)) return false; Product p = (Product) obj; return p.productId == productId; } } Resource entity: @Entity public class Resource implements Serializable { ... @OneToMany(mappedBy="resource", fetch=FetchType.EAGER) private List<ProductResource> productResources = new ArrayList<ProductResource>(); ... public void setProductResource(List<ProductResource> productResource) { this.productResources = productResource; } public List<ProductResource> getProductResources() { return productResources; } public boolean equals(Object obj) { if (obj == this) return true; if (obj == null) return false; if (!(obj instanceof Resource)) return false; Resource r = (Resource) obj; return (long)resourceId==(long)r.resourceId; } } ProductResource Entity: This is a JoinTable (association class) with additional properties (amount). It maps Product and Resources. @Entity public class ProductResource implements Serializable { ... @JoinColumn(nullable=false, updatable=false) @ManyToOne(fetch=FetchType.EAGER, cascade=CascadeType.PERSIST) private Product product; @JoinColumn(nullable=false, updatable=false) @ManyToOne(fetch=FetchType.EAGER, cascade=CascadeType.PERSIST) private Resource resource; private int amount; public void setProduct(Product product) { this.product = product; if(!product.getProductResources().contains((this))){ product.getProductResources().add(this); } } public Product getProduct() { return product; } public void setResource(Resource resource) { this.resource = resource; if(!resource.getProductResources().contains((this))){ resource.getProductResources().add(this); } } public Resource getResource() { return resource; } ... public boolean equals(Object obj) { if (obj == this) return true; if (obj == null) return false; if (!(obj instanceof ProductResource)) return false; ProductResource pr = (ProductResource) obj; return (long)pr.productResourceId == (long)productResourceId; } } This is the Session Bean (running on glassfish). @Stateless(mappedName="PersistenceManager") public class PersistenceManagerBean implements PersistenceManager { @PersistenceContext(unitName = "local_mysql") private EntityManager em; public Object create(Object entity) { em.persist(entity); return entity; } public void delete(Object entity) { em.remove(em.merge(entity)); } public Object retrieve(Class entityClass, Long id) { Object entity = em.find(entityClass, id); return entity; } public void update(Object entity) { em.merge(entity); } } I call the session Bean from a java client: public class Start { public static void main(String[] args) throws NamingException { PersistenceManager pm = (PersistenceManager) new InitialContext().lookup("java:global/BackITServer/PersistenceManagerBean"); ProductResource pr = new ProductResource(); Product p = new Product(); Resource r = new Resource(); pr.setProduct(p); pr.setResource(r); ProductResource pr_stored = (ProductResource) pm.create(pr); pm.delete(pr_stored); Product p_ret = (Product) pm.retrieve(Product.class, pr_stored.getProduct().getProductId()); // prints out true ???????????????????????????????????? System.out.println(p_ret.getProductResources().contains(pr_stored)); } } So here comes my problem. Why is the ProductResource entity still in the List productResources(see code above). The productResource tuple in the db is gone after the deletion and I do newly retrieve the Product entity. If I understood right every method call of the client happens in a new persistence context, but here i obviously get back the non-refreshed product object!? Any help is appreciated Thanks Marcel

  • IntelliJ IDEA plugin development: Get classes VirtualFile (or paths) for a specific source VirtualFi

    - by Ran Biron
    Hi all. This is a cross-post from http://www.jetbrains.net/devnet/message/5264436#5264436 - I failed to get any answer on that forum for two weeks now, so I'm re-asking it here (please don't flame). This question refers to plugin development for the IntelliJ IDEA IDE, specifically targeting java development: Is there any API to get the list of .class files for given source file? I'm trying to write a plugin that creates a binary patch jar based on a changelist. I've managed to get the changelist and, from it, a list of source files (VirtualFile). Now I'm trying to get the compiled class files for these source files (I don't mind preforming a "make" or relying on the previous compile output). I've played a bit with ProjectFileIndex but could only find the classes root. I'd hate to do a "dumb" path-based search because inner classes (and inner anonymous classes) would make it difficult to get correctly. Is there such an API? Or am I doomed to parse the paths? Thanks, Ran.

  • Vista 64-bits development tools

    - by Workshop Alex
    Well, okay. There's Visual Studio 2008 and Embarcadero Delphi/Studio that are both able to create 64-bits .NET applications for Vista. And of course a lot of 32-bits applications will run on 64-bits Vista. If not, it's always possible to install VMWare to create a virtual 32-bits Windows XP system to run 32-bits applications. So, plenty of options. But what I would like to see is a list of true 64-bits applications for Windows Vista and better. So if you know any useful 64-bits product, please share! (Especially compilers that generate native 64-bits code.) Tools would basically be anything that would make development a bit easier. Thus, debugging tools, image processing tools to create icons and bitmaps, hex editors to check the contents of binary files, XML editors to change XML files, etc. The tools from SysInternals, for example, seem to provide 64-bits versions or even support 64-bits systems natively. But how about all those other editors, viewers, browsers and other tools that we developers like to use? A 64-bits version of the Norton Commander/Midnight Commander or other file managers would be nice too. And with compilers, how about COBOL/ForTran/ADA/SmallTalk/Lisp/Whatever compiler/languages for Vista? I would just like to see a complete list of anything useful for 64-bits development.

  • Does <httpRedirect> in web.config work in a mono setup? Or is it IIS7 specific?

    - by Crystal
    We had some content restructure recently and I'd like to put in some redirect rules into web.config so bookmarks to the old pages can get routed to their new locations/pages. I tried using this approach: <location path="~/product/productA.aspx"> <system.webServer> <httpRedirect enabled="true" destination="~/product/category/productA.aspx" exactDestination="false" childOnly="true" httpResponseStatus="Permanent" /> </system.webServer> </location> But all I'm getting when I go to "http://www.oursite.com/product/productA.aspx" is our http 404 page. Am I doing something wrong, or is the httpRedirect tag in web.config not supported in mono? worked, but not ideal for what we want to achieve. Thank you :)

  • Test-First development tool for SQL Server 2005?

    - by Jeff Jones
    For several years I have been using a testing tool called qmTest that allows me to do test-driven database development for some Firebird databases. I write a test for a new feature (table, trigger, stored procedure, etc.) until it fails, then modify the database until the test passes. If necessary, I do more work on the test until it fails again, then modify the database until the test passes. Once the test for the feature is complete and passes 100% of the time, I save it in a suite of other tests for the database. Before moving on to another test or a deployment, I run all the tests as a suite to make sure nothing is broken. Tests can have dependencies on other tests, and the results are recorded and displayed in a browser. Nothing new here, I am sure. Our shop is aiming toward standardizing on MSSQLServer and I want to use the same procedure for developing our databases. Does anyone know of tools that allow or encourage this kind of development? I believe the Team System does, but we do not own that at this point, and probably will not for some time. I am not opposed to scripting, but would welcome a more graphical environment. Any suggestions?

  • Yaml::load_file acting different between development and production (Rails)

    - by James
    Hi, I am completely stumped at the nature of this problem. We export data from our application into a 'cleaned' YAML file (stripping out IDs, created_at etc). Then we (will) allow users to import these files back into the application - it is the import that is completely bugging me out. In development, YAML::load_file(params[:uploaded_data].local_path) returns an array of YAML::Objects's (and it doesn't matter which of the number of different ways the file could be loaded): [#{"exception_count"="0", "title"="Start", "amount"="70.00", "colour"=nil, "repeat_type_id"="0", "repeat_interval"="1"}}, etc etc] Which is very nice, as the attributes also include the (associated model) exceptions that you see an exception_count for. However on production (rails 2.3.2, running REE 1.8.7 and 1.8.6 for testing, tested on two different production env's, and running production locally) it returns an array of the Objects within the YAML - in this case, Event: [#, repeat_type_id: 0, colour: nil, repeat_interval: 1, exception_count: 0, etc etc] Now this would be just perplexing if it also included the associated model Exception with it - however it doesn't. Can anyone at all shed some light on why the Yaml parser would behave so differently between production and development? I'm on rails 2.3.2, running REE 1.8.7; however I've also tested running Ruby 1.8.6 with exactly the same results. Thanks for any help!

  • fastest SCM tool available for Embedded software development

    - by wrapperm
    Hi All, In my company, presently we are using Rational clearcase as the Software Configuration Management tool for our Embedded software development. The software is basically for Automobiles, to be specific for Engines (I dont think these information really matters). But I find Clearcase to be very slow is performing any the activities (accesing files, branching and labelling), in addition to which there are various other limitations. We have recently decided to research on some free & open source, distributed version control system which could be able to handle our large projects with speed and efficiency. This tool should be a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server. Branching and merging are fast and easy to do. It should have multisite development facility. With these above mentioned requirement, we have come up with some of the tools that are presently available in the market: GIT, Mercurial, Bazaar, Subversion, CVS, Perforce, and Visual SourceSafe. I need everybody's help in finding me an approrpiate SCM tool for me which meets the above mentioned requirements. Thanking you in Advance, Rahamath.

  • Is MVVM killing silverlight development?

    - by DeanMc
    This is a question I have had rattling around in my head for some time. I had a chat with a guy the other night who told me he would not be using the navigational framework because he could not figure out how it works with MVVM. As much as I tried to explain that patterns should be taken with a pinch of salt he would not listen. My point is this, patterns are great when they solve some problem. Sometimes only part of the pattern solves a particular problem while the other parts of it cause different problems. The goal of any developer is to build a solid application using a combination of patterns know how and foresight. I feel MVVM is becoming the one pattern to rule them all. As it is not directly supported by .Net some fancy business is needed to make it work. I feel that people are missing the point of the pattern, which is loosely coupled, testable code and instead jumping through hoops and missing out on great experiences trying to follow MVVM to the letter. MVVM is great but I wish it came with a warning or disclaimer for newbies as my fear is people will shy away from silverlight development for fear of being smacked with the mvvm stick. EDIT: Can I just add as an edit, I use and agree with MVVM as a pattern I know when it is and isn't feasible in my projects. My issue is with the encompassing nature it is taking, as if it HAS to be used as part of development. It is being used as an integral feature and not a pattern, which it is.

  • Web development: Haskell or Scheme

    - by Robert E. Lester
    I would like to to choose one of these languages for building web applications. I'm not interested in framework per say, but have the following needs: Rapid development. Easy to scale. Strong community for the web. Quick and easy to deploy. I'm very familiar with Haskell, and have some familiarity with scheme (in particular PLT). Scheme appeals to me as good candidate for web development due to it's simple syntax which is homogenous across libraries. I state this despite my subjective opinion that Haskell is a 'cleaner' language. Haskell web apps seem to require learning and building a patchwork of different combinator libraries. On the plus side, I realise this can be quite expressive, although I'd prefer to eliminate impedance mismatches where possible. While scheme-plt looks to be a good fit, I can find but one example of it being used in the "real world". Haskell doesn't seem to fair too much better here, but there seems to be a bigger community behind the web side. Please help me make up my mind. For the most part I'm interested in real-world use cases.

  • Ultra-Portable Laptop or Tablet PC for Development and Sketching

    - by Nelson LaQuet
    I am a software developer that primarily writes in PHP, [X]HTML, CSS, Javascript, C# and C++. I use Eclipse for web development, Visual Studio 2008 for C++ and C# work, TortoiseSVN, Subversion server for local repositories, SQL Server Express, Apache and MYSQL. I also use Office 2007 for word processing and spreadsheets and use Vista Ultimate 64 as my primary operating system. The only other things I do on my laptop are watch movies, surf the internet and listen to music. I currently have a Acer Aspire 5100 (1.4 GHz AMD Turion X2, 2 GB of RAM and a 15.4" screen). This thing does not cut it in performance or portability, and in addition, my DVD drive failed. And before anybody posts about vista: I have had XP Professional 32 on it for the last two years, and recently upgraded to Vista 64. It is actually faster (with areo disabled) then XP; so it is not the OS that is causing the laptop to be slow. I usually sketch a lot, for explaining things, developing user interfaces and software architecture. Because of my requirements, I was thinking about a Lenovo X61 Tablet PC. It outperforms my current laptop, is significantly more portable, and... is a tablet. My question is: do any other software developers use this (or other tablets) for programming? Does it help to be able to sketch on the computer itself? And is it capable of being a good development machine? Will it handle the above software listed? If not, what is the best ultra-portable laptop that is good for programming? Or are ultra-portable laptops even good for programming? I could manage with my 15.4" screen, but am spoiled by my two 19" at my home desktop and my job's workstation.

  • Magento: add product twice to cart, with different attributes!

    - by Peter
    Hello all, i have been working with this for a whole day but i cannot find any solution: I have a product (lenses), which has identical attributes, but user can choose one attribute set for one eye and another attribute set for another. On the frontend i got it ok, see it here: http://connecta.si/clarus/index.php/featured/acuvue-oasys-for-astigmatism.html So the user can select attributes for left or right eye, but it is the same product. I build a function, wich should take a product in a cart (before save), add other set of attributes, so there should be two products in the cart. What happens is there are two products, but with the same set of attributes??? Here is the snippet of the function: $req = Mage::app()-getRequest(); $request[’qty’] = 1; $request[’product’] = 15; $request[’uenc’] = $req-get(’uenc’); $request[’options’][1] = 1; $request[’options’][3] = 5; $request[’options’][2] = 3; $reqo = new Varien_Object($request); $newitem = $quote-addProduct($founditem-getProduct(), $reqo); //add another one ------------------------------------------ $request[’qty’] = 1; $request[’product’] = 15; $request[’uenc’] = $req-get(’uenc’); $request[’options’][1] = 2; $request[’options’][3] = 6; $request[’options’][2] = 4; $reqo = new Varien_Object($request); $newitem = $quote-addProduct($founditem-getProduct(), $reqo); Or another test, with some other functions (again, product added, with 2 quantity , but same attributes...): $req = Mage::app()-getRequest(); $request[’qty’] = 1; $request[’product’] = 15; $request[’uenc’] = $req-get(’uenc’); $request[’options’][1] = 2; $request[’options’][3] = 6; $request[’options’][2] = 4; $product = $founditem-getProduct(); $cart = Mage::getSingleton(’checkout/cart’); //delete all first… $cart-getItems()-clear()-save(); $reqo = new Varien_Object($request); $cart-addProduct($founditem-getProduct(), $reqo); $cart-getItems()-save(); $request[’options’][1] = 1; $request[’options’][3] = 5; $request[’options’][2] = 3; $reqo = new Varien_Object($request); $cart-addProduct($founditem-getProduct(), $reqo); $cart-getItems()-save(); i really dont know what more to do, please any advice, this is my first module in magento… thank you, Peter

  • The Implications of Modern Day Software Development Abstractions

    - by Andreas Grech
    I am currently doing a dissertation about the implications or dangers that today's software development practices or teachings may have on the long term effects of programming. Just to make it clear: I am not attacking the use abstractions in programming. Every programmer knows that abstractions are the bases for modularity. What I want to investigate with this dissertation are the positive and negative effects abstractions can have in software development. As regards the positive, I am sure that I can find many sources that can confirm this. But what about the negative effects of abstractions? Do you have any stories to share that talk about when certain abstractions failed on you? The main concern is that many programmers today are programming against abstractions without having the faintest idea of what the abstraction is doing under-the-covers. This may very well lead to bugs and bad design. So, in you're opinion, how important is it that programmers actually know what is going below the abstractions? Taking a simple example from Joel's Back to Basics, C's strcat: void strcat( char* dest, char* src ) { while (*dest) dest++; while (*dest++ = *src++); } The above function hosts the issue that if you are doing string concatenation, the function is always starting from the beginning of the dest pointer to find the null terminator character, whereas if you write the function as follows, you will return a pointer to where the concatenated string is, which in turn allows you to pass this new pointer to the concatenation function as the *dest parameter: char* mystrcat( char* dest, char* src ) { while (*dest) dest++; while (*dest++ = *src++); return --dest; } Now this is obviously a very simple as regards abstractions, but it is the same concept I shall be investigating. Finally, what do you think about the issue that schools are preferring to teach Java instead of C and Lisp ? Can you please give your opinions and your says as regards this subject? Thank you for your time and I appreciate every comment.

  • Need help accessing PHP DOM elements

    - by Michael Pasqualone
    Hey guys, I have the following HTML structure that I am trying to pull information from: // Product 1 <div class="productName"> <span id="product-name-1">Product Name 1</span> </div> <div class="productDetail"> <span class="warehouse">Warehouse 1, ACT</span> <span class="quantityInStock">25</span> </div> // Product 2 <div class="productName"> <span id="product-name-2">Product Name 2</span> </div> <div class="productDetail"> <span class="warehouse">Warehouse 2, ACT</span> <span class="quantityInStock">25</span> </div> … // Product X <div class="productName"> <span id="product-name-X">Product Name X</span> </div> <div class="productDetail"> <span class="warehouse">Warehouse X, ACT</span> <span class="quantityInStock">25</span> </div> I don't have control of the source html and as you'll see productName and it's accompanying productDetail are not contained within a common element. Now, I am using the following php code to try and parse the page. $html = new DOMDocument(); $html->loadHtmlFile('product_test.html'); $xPath = new DOMXPath($html); $domQuery = '//div[@class="productName"]|//div[@class="productDetail"]'; $entries = $xPath->query($domQuery); foreach ($entries as $entry) { echo "Detail: " . $entry->nodeValue) . "<br />\n"; } Which prints the following: Detail: Product Name 1 Detail: Warehouse 1, ACT Detail: 25 Detail: Product Name 2 Detail: Warehouse 2, ACT Detail: 25 Detail: Product Name X Detail: Warehouse X, ACT Detail: 25 Now, this is close to what I want. But I need to do some processing on each Product, Warehouse and Quantity stock and can't figure out how to parse it out into separate product groups. The final output I am after is something like: Product 1: Name: Product Name 1 Warehouse: Warehouse 1, ACT Stock: 25 Product 2: Name: Product Name 2 Warehouse: Warehouse 2, ACT Stock: 25 I can't just figure it out, and I can't wrap my head around this DOM stuff as the elements don't quite work the same as a standard array. If anyone can assist, or point me in the right direction I will be ever appreciative.

  • cross-platform development for mobile devices

    - by user924
    What language/framework is best worth learning for mobile application development? My specific situation is that I'm very familiar with Java and C++ (I especially love Qt), but have limited experience with other languages. Some options I'm considering: 1) Learn Objective-C and all the iPhone-specific tools I do have access to a mac. The downside here is I'm restricted to the iPhone, so I'd have to rewrite almost everything if I wanted to branch off into another mobile device (or move later to a cross-platform framework). Even after knowing Objective-C, it seems like other frameworks might be more efficient/faster to code in? 2) Use some existing cross-platform framework for development I've looked at rhomobile, but I only have limited experience with Ruby (and at first glance, it might be a little pricey comapred to other options). Appcelerator also looks popular and nice, but it uses html/css/javascript. Airplaysdk looks good, but it's new and I haven't been able to see much written about it (is it worth going for?). 3) Wait for something better to come along How far away is Qt for the iPhone? That would be ideal, but it isn't available now. So what do you recommend? Productivity/efficiency is my top priority, although learning a useful language for the long term would also be okay. Thanks

  • WinUSB failing on non-development computers

    - by Giawa
    Good afternoon, WinUSB is working well on the development computer that I am using (Win XP SP3). I am able to download new firmware to the Cypress FX2, and then connect to the new USB device once it 'renumerates'. However, if I've tried the same code with the WinUSB driver on a few other computers (Win XP SP3, Win7 x64) and they both returned the error "A device attached to the system is not functioning." when trying to use CreateFile to get a handle to the USB device. The devicePath was found successfully, so I'm not sure why it cannot connect to the device. Furthermore, the device manager states that my device is working properly. I'm curious if I'm missing something when compiling the code? I would guess that my development computer has something installed on it that the other computers do not? Or perhaps it's a power setting and the device is going to sleep (although I've fooled around with the Power Options on each computer to no avail). Does anyone have any ideas? I've compiled under Visual Studio 2008, and have installed the Microsoft C++ 2008 Redistributable Package on the computers that I've tested on. Thanks, Giawa

  • Releasing from development into production in maven

    - by Bruce
    Hi all, I'm confused about the use of maven in development and production environments - I'm sure it's something simple that I'm missing. Grateful for any help.. I set up maven inside eclipse on my local machine and wrote some software. I really like how it's made things like including dependent jars very easy. So that's my development environment. But now I want to release the project to production on a remote server. I've searched the documentation, but I can't figure out how it's supposed to work or what the maven best practice is.. Are you supposed to: a) Also be running maven on your production environment, and upload all your files to your production environment and rebuild your project there? (Something in me baulks at the idea of rebuilding 'released' code on the production server, so I'm fairly sure this isn't right..) b) use mvn:package to create your jar file and then copy that up to production? (But then what of all those nice dependencies? Isn't there a danger that your tested code is now going to be running against different versions of the dependent jars in the production environment, possibly breaking your code? Or missing a jar..?) c) Something else that I'm not figuring out.. Thanks in advance for any help!

  • is NATURAL JOIN any better than SELECT FROM WHERE in terms of performance ?

    - by ashy_32bit
    Today I got into a debate with my project manager about Cartesian products. He says a 'natural join' is somehow much better than using 'select from where' because the later cause the db engine to internally perform a Cartesian product but the former uses another approach that prevents this. As far as I know, the natural join syntax is not any different in anyway than 'select from where' in terms of performance or meaning, I mean you can use either based on your taste. SELECT * FROM table1,table2 WHERE table1.id=table2.id SELECT * FROM table1 NATURAL JOIN table2 please elaborate about the first query causing a Cartesian product but the second one being somehow more smart

  • ZF2 namespace and file system

    I have standard Application module in ZF2. It's configured by default, I didn't change anything. I just added some stuff: module/ Application/ src/ Application/ Entity/ Product/ **Product.php** Controller/ **IndexController.php** Product.php namespace Application\Entity; class Product { } IndexController.php namespace Application\Controller; use Zend\Mvc\Controller\AbstractActionController; use Zend\View\Model\ViewModel; use Application\Entity\Product; class IndexController extends AbstractActionController { public function indexAction() { $product = new Product(); } } and I get following error: Fatal error: Class 'Application\Entity\Product' not found in \module\Application\src\Application\Controller\IndexController.php on line 20 I use the same namespace, but it doesn't see it.

P.S: If I will change Product.php to be the following: namespace Application\Entity\Product; class Product { } then in the IndexController.php the following code will be working: namespace Application\Controller; use Zend\Mvc\Controller\AbstractActionController; use Zend\View\Model\ViewModel; use Application\Entity\Product\Product; class IndexController extends AbstractActionController { public function indexAction() { $product = new Product(); } }

  • Company wants to write custom project management tool, rather then use third party product.

    - by Jason Evans
    At the company I work, we are really wanting to get into the agile methodology for developing software. One thing that I'm not excited about is the fact that management wants us to build a custom project management feature inside the company's Intranet. I think this is a total waste of time. There are many great third party tools available (e.g. Axosoft OnTime) that can do everything we need, and more. For how much development time it would cost us to build our own project management module, we could buy numerous licences for a third party product. One concern is that, whilst we are writing code for a client, and using our custom Intranet project management module, we find bugs in the module that need fixing ASAP. That means having to stop work on the client code to fix the Intranet. That just puts shivers down my spine. Another worry I have is lack of functionality. This custom module is going to be so basic, that it will just feel really crap to use. That might sound a bit snooty, but for goodness sake, many third party tools are so feature rich, that the idea of having to write our own tool makes feel very uneasy. In fact, I can't be bothered. What do you guys think? I'm going to raise this issue with my boss, since I feel it's such an important topic to talk about. EDIT: Thanks for the great responses, much appreciated. To summarize some of them: Money Naturally my boss does want to save money, by not forking out a few hundred £'s for licences. However, for us to write a custom tool, it will take x number of days, multiplied by approx £500, which is our costs. I don't see the business value in this. Management have mentioned that they want to sell the Intranet as a product in the future, but it's so custom to our needs (and downright basic), that in order to give it to another client, I can see us having to fork a version of the code and rebuild the majority of it anyway. So it's not like we're gaining anything there in reuse. Features Having our own custom module means not feature bloat - only the functionality we require will be in the product. My issue is that there are plenty of free, open-source project management tools out there with minimal features already. So even if cost is an issue, we could look into open-source. Again it all boils down to the fact that I don't see the point in writing a project management tool in this day and age. It's a bit like writing your own web browser - why?, what's the point? Although management are asking for this tool, just because they are, it does not mean I'm going to please them and do it just because they asked for it. If something does not make sense, then I will raise it as a concern. At the end of the day, it's the developers who write the code, it's the developers who make money for a business. Thus, as far I'm concerned, the devs have a very big role in deciding how a company should manage projects and what tools are used. "I am Spartan, argh!" :) Hmm, I've not been able to make this question a wiki for some reason, thus I'm going to have to pick an answer to accept. Cheers. Jas.

  • Scrum Master Stephen Forte Teaches Agile Development, Silverlight and BI at GIDS 2010

    - by rajesh ahuja
    Great Indian Developer Summit 2010 – Gold Standard for India's Software Developer Ecosystem Bangalore, March 25, 2010: The author of several books on application and database development including Programming SQL Server 2008 and certified Scrum Master Stephen Forte is coming this summer to India's biggest summit for the developer ecosystem - Great Indian Developer Summit. At the summit, Stephen will conduct a workshop guaranteed to give attendees a jump start in taking a certified scrum master exam. Scrum, one of the most popular Agile project management and development methods, which is starting to be adopted at major corporations and on very large projects. After an introduction to the basics of Scrum like project planning and estimation, the Scrum Master, team, product owner and burn down, and of course the daily Scrum, Stephen will show many real world applications of the methodology drawn from his own experience as a Scrum Master. Negotiating with the business, estimation and team dynamics are all discussed as well as how to use Scrum in small organizations, large enterprise environments and consulting environments. Stephen will also discuss using Scrum with virtual teams and an off-shoring environment. He will then take a look at the tools we will use for Agile development, including planning poker, unit testing, and much more. On 20th April at the GIDS.NET Conference, Stephen will also conduct a series of sessions on Microsoft computing technologies. He will teach how to build data driven, n-tier Rich Internet Applications (RIA) with Silverlight 4.0. Line of business applications (LOB) in Silverlight 4.0 are easy by tapping the power of WCF RIA Services, the Silverlight Toolkit, and elevated out of browser support. Stephen's demo centric session will walk you through an example of building a LOB application with Silverlight 4.0. See how Silverlight and WCF RIA Services support domain logic, services, data binding, validation, server based paging, authentication, authorization and much more. Silverlight 4.0 means business. Silverlight runs C# and Visual Basic code, and so it seems natural that a business application might share some code between the Silverlight client and its ASP.NET Web server. You may want to run some code client-side for interactivity, but re-run that code on the server for security or reliability. This is possible, and there are several techniques you can use to accomplish this goal. In Stephen's second talk learn about the various techniques and their pros and cons. Some techniques work better in C#, others in VB. Still others are simpler with a little extra tooling or code-generation. Any serious Silverlight business application will almost certainly face this issue, and this session gets you going fast. In the third talk, Stephen will explain how to properly architect and deploy a BI application using a mix of some exciting new tools and some old familiar ones. He will start with a traditional relational transaction centric database (OLTP) and explore ways to build a data warehouse (OLAP), looking at the star and snowflake schemas. Next he will look at the process of extraction, transformation, and loading (ETL) your OLTP data into your data warehouse. Different techniques for ETL will be described and the various tradeoffs will be discussed. Then he will look at using the warehouse for reporting, drill down, and data analysis in Microsoft Excel's PowerPivot 2010. The session will round off by showing how to properly build a cube and build a data analysis application on top of that cube, and conclude by looking at some tools to help with the data visualization process.

  • WPF or WinForms for Game Development and learning resources?

    - by Stephen Lee Parker
    I'm looking to create a game framework for my own personal use... I want to use WPF, but I'm unsure if that is a wise choice... The games I will be writing should not require high performance graphics, so I am hoping to build on native classes... I do not want to rely on external DLL's unless I generate them myself. The games will be for young children, say 4 to 8. Most will be learning puzzles or simple shooters. The most advanced will be a platform game (non-scrolling screen like the old Atari Miner 2049er game). I think I know how to write something like the old Atari Chopper Command (partially written and my 4 year old loves it, but I used WinForms and GDI), Pac-Man, Tetris, Astroids, Space Invaders, Slider Puzzle, but I do not really know how to write the platform game... In my mind, I'm getting caught in collision detection and how to make a character jump and how to make a character walk up a slope or steps... Can anyone point me to information on developing a platform game in C#? Would you suggest WinForms or WPF for game development? I'm not looking for great graphics and speed, just entertaining game play...
