• Mobile Web Applications – A guide for professional development

  - by JuergenKress

  (Tobias Bosch, Stefan Scheidt, Torsten Winterberg / Opitz Consulting Deutschland GmbH). There is a real hype around mobile solutions. Smartphones and tablets are everywhere. Frontend architecture is changing quickly to adopt cross browser technologies like HTML5 and extensive JavaScript-based development. In this book we introduce our software development process to build test-driven Single-Page JavaScript Web Applications, which will be the future next to native apps. We start with a short introduction of our RYLC showcase (know from our SOA articles), give a very short introduction to JavaScript, then talk about jQuery Mobile, Angular JS, Testing, Backend-communication and we close with deploying our RYLC-Webapp as a hybrid app using the PhoneGap (Cordova) framework. Don’t expect too much theory – it’s a practical guide explaining how RYLC Web App was built, to kickstart your own development. Currently only available in German as paperback and eBook.

• Apply bone tranforms when importing FBX in XNA

  - by hichaeretaqua

  Preconditions: I have some models, that does only contain some meshes and one texture. There is no animation within the model. An example: a model of a table. I want to draw the Model with a custom effect, so I have to swap the effect after loading the model. In order to draw them correctly, I have to apply the bone transformation manually on each draw for each mesh and effect as can be seen here. So there are two questions: Is there a option during import that allows my to apply the bone transformation on all vertices, so that during draw call I should not have to do this? Is there a option during import that merges all vertices into a Vertex- and IndexBuffer, that allows me to draw the whole model with just one call? I'm pretty sure that the build-in "Autodesk FBX - XNA Framework" does not support this features, but maybe there is an other imported available or an other possibility I missed. The aim is to speed up rendering a little bit especially by using instancing. So having one VertexBuffer to draw at one time would be pretty nice.

• How to effectively design a piece of software

  - by ti83plus

  Im a compsci student and ive got some experience in various languages and paradigms c/java/python/ruby/html/css/scheme/sql/asp(classic). I realise that i want to have some software in my portfolio for future job hunting even tho i still have 2 years left of my education. Ive got a pretty good idea of what i want to make, its a webapp. Most shops around here are either .net or java and since i know java best and dont have access to ms developer tools im thinking i should go with java. Even tho i feel i know the principles of OOP pretty good ive got no clue how to go from my idea to a working solution. Where can i access information about designing the underlying architechture of my solution? Also i would like to know what other technologies i should train on, my current list includes javascript(and possibly a javascript library) some sort of java web framework tips are appreciated. I would like to add support for android/iphone apps in the future and this is something i have to take into account when designing the app. I have done a course on software engineering but i found this to be more centered around project management ideas then the actual design and implementation. So i would like tips on technologies i should focus on to get the most out of my time without the massive overhead of huge config processes but at the same time keep my project viable in a business sense, so that i use technologies that are relevant for business (java developer jobs). And i would also like tips on where i can learn more about the design process around a software project, i will be working mostly alone. But i find the approach ive used up until now (start coding and figure it out as you go) wont suffice.

• 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.

• SSIS Catalog: How to use environment in every type of package execution

  - by Kevin Shyr

  Here is a good blog on how to create a SSIS Catalog and setting up environments.  http://sqlblog.com/blogs/jamie_thomson/archive/2010/11/13/ssis-server-catalogs-environments-environment-variables-in-ssis-in-denali.aspx Here I will summarize 3 ways I know so far to execute a package while using variables set up in SSIS Catalog environment. First way, we have SSIS project having reference to environment, and having one of the project parameter using a value set up in the environment called "Development".  With this set up, you are limited to calling the packages by right-clicking on the packages in the SSIS catalog list and select Execute, but you are free to choose absolute or relative path of the environment. The following screenshot shows the 2 available paths to your SSIS environments.  Personally, I use absolute path because of Option 3, just to keep everything simple for myself. The second option is to call through SQL Job.  This does require you to configure your project to already reference an environment and use its variable.  When a job step is set up, the configuration part will require you to select that reference again.  This is more useful when you want to automate the same package that needs to be run in different environments. The third option is the most important to me as I have a SSIS framework that calls hundreds of packages.  The main part of the stored procedure is in this post (http://geekswithblogs.net/LifeLongTechie/archive/2012/11/14/time-to-stop-using-ldquoexecute-package-taskrdquondash-a-way-to.aspx).  But the top part had to be modified to include the logic to use environment reference. CREATE PROCEDURE [AUDIT].[LaunchPackageExecutionInSSISCatalog] @PackageName NVARCHAR(255) , @ProjectFolder NVARCHAR(255) , @ProjectName NVARCHAR(255) , @AuditKey INT , @DisableNotification BIT , @PackageExecutionLogID INT , @EnvironmentName NVARCHAR(128) = NULL , @Use32BitRunTime BIT = FALSE AS BEGIN TRY DECLARE @execution_id BIGINT = 0; -- Create a package execution IF @EnvironmentName IS NULL BEGIN   EXEC [SSISDB].[catalog].[create_execution]     @package_name=@PackageName,     @execution_id=@execution_id OUTPUT,     @folder_name=@ProjectFolder,     @project_name=@ProjectName,     @use32bitruntime=@Use32BitRunTime; END ELSE BEGIN   DECLARE @EnvironmentID AS INT   SELECT @EnvironmentID = [reference_id]    FROM SSISDB.[internal].[environment_references] WITH(NOLOCK)    WHERE [environment_name] = @EnvironmentName     AND [environment_folder_name] = @ProjectFolder      EXEC [SSISDB].[catalog].[create_execution]     @package_name=@PackageName,     @execution_id=@execution_id OUTPUT,     @folder_name=@ProjectFolder,     @project_name=@ProjectName,     @reference_id=@EnvironmentID,     @use32bitruntime=@Use32BitRunTime; END

• Sandcastle Help File Builder - October 2010 release

  - by TATWORTH

  At http://shfb.codeplex.com/releases/view/92191, the latest Sandcastle has been released. I am pleased to say that it incorporates the generic version of a fix, I originated that allows projects including Crystal Reports to be documented.Here is the relevant passage from the help file:"The default configuration for MRefBuilder has been updated to ignore the Crystal Reports licensing assembly (BusinessObjects.Licensing.KeycodeDecoder) if it fails to get resolved. This assembly does not appear to be available and ignoring it prevents projects that include Crystal Reports assemblies from failing and being unbuildable."There are many other fixes. Here are the release notes:IMPORTANT: On some systems, the content of the ZIP file is blocked and the installer may fail to run. Before extracting it, right click on the ZIP file, select Properties, and click on the Unblock button if it is present in the lower right corner of the General tab in the properties dialog.This release supports the Sandcastle October 2012 Release (v2.7.1.0). It includes full support for generating, installing, and removing MS Help Viewer files. This new release supports Visual Studio 2010 and 2012 solutions and projects as documentation sources, and adds support for projects targeting the .NET 4.5 Framework, .NET Portable Library 4.5, and .NET for Windows Store Apps.See the Sandcastle 2.7.1.0 Release Notes for details on all of the changes made to the underlying Sandcastle tools and presentation styles.This release uses the Sandcastle Guided Installation package.

• 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

• Non-blocking ORM issues

  - by Nikolay Fominyh

  Once I had question on SO, and found that there are no non-blocking ORMs for my favorite framework. I mean ORM with callback support for asynchronous retrieval. The ORM would be supplied with a callback or some such to "activate" when data has been received. Otherwise ORM needs to be split of in a separate thread to guarantee UI responsiveness. I want to create one, but I have some questions that blocking me from starting development: What issues we can meet when developing ORM? Does word "non-blocking" before word "ORM" will dramatically increase complexity of ORM? Why there are not much non-blocking ORMs around? Update: It looks, that I have to improve my question. We have solutions that already allows us to receive data in non-blocking way. And I believe that not all companies that use such solutions - using raw SQL. We want to create more generic solution, that we can reuse in future projects. What difficulties we can meet?

• Tomcat + Spring + CI workflow

  - by ex3v

  We're starting our very first project with Spring and java web stack. This project will be mainly about rewriting quite large ERP/CRM from Zend Framework to Java. Important factor in my question is that I come from php territory, where things (in terms of quality) tend to look different than in java world. Fatcs: there will be 2-3 developers, at least one of developers uses Windows, rest uses Linux, there is one remote linux-based machine, which should handle test and production instances, after struggling with buggy legacy code, we want to introduce good programming and development practices (CI, tests, clean code and so on) client: internal, frequent business logic changes, scrum, daily deployments What I want to achieve is good workflow on as many development stages as possible (coding - commiting - testing - deploying). The problem is that I've never done this before, so I don't know what are best practices to do this. What I have so far is: developers code locally, there is vagrant instance on every development machine, managed by puppet. It contains the same linux, jenkins and tomcat versions as production machine, while coding, developer deploys to vagrant machine, after local merge to test branch, jenkins on vagrant handles tests, when everything is fine, developer pushes commits and merges jenkins on remote machine pulls commit from test branch, runs tests and so on, if everything looks green, jenkins deploys to test tomcat instance Deployment to production is manual (altough it can be done using helping scripts) when business logic is tested by other divisions and everything looks fine to client. Now, the real question: does above make any sense? Things that I'm not sure about: Remote machine: won't there be any problems with two (or even three, as jenkins might need one) instances of same app on tomcat? Using vagrant to develop on php environment is just vise. Isn't this overkill while using Tomcat? I mean, is there higher probability that tomcat will act the same on every machine? Is there sense of having local jenkins on vagrant?

• Belgrade Open Source Software Development Center

  - by Tori Wieldt

  A new Open Source Software Development Center is open at University of Belgrade Serbia. It centers around using Java & NetBeans as open source projects to learn from and contribute to. Assistant Professor Zoran Sevarac says that not only does the center allow him to teach software development using open source projects, but also "we are improving our University courses based on the experience we get from working on open source code."  Some of the projects underway are a NetBeans UML plugin; Neuroph (a Java neural network framework, with a NetBeans Platform-based UI); a NetBeans DOAP Plugin; WorkieTalkie (NetBeans chat plugin); and 2D and 3D visualization plugins for NetBeans. Here's video describing the NetBeans UML plugin: University of Belgrade also has an official university course about open source development, where students learn to use development tools, work in teams, participate in open source projects and learn from real world software development projects. Students, teachers, and researchers at the University of Belgrade, and any member of the open source community are welcome to come to learn software development from successful open source projects. For more information, you can contact Zoran Sevarac (@neuroph on Twitter).

• Algorithms or patterns for a linked question and answer cost calculator

  - by kmc

  I've been asked to build an online calculator in PHP (and the Laravel framework). It will take the answers to a series of questions to estimate the cost of a home extension. For example, a couple of questions may be: What is the lie of your property? Flat, slightly inclined, heavily inclined. (these suggestive values could have specific values in the underlying calculator like, 0 degrees, 5 degrees, 10 degrees. What is your current flooring system? Wooden, or concrete? These would then impact the results of other questions. Once the size of the extension has been input, the lie of the land will affect how much site works will cost, and how much rubbish collection will cost. The second question will impact the cost of the extensions flooring, as stumping and laying floorboards is a different cost to laying foundations and a concrete slab. It will also influence what heating and cooling systems are available in the calculator. So it's VERY interlinked. The answer to any question can influence the options of other questions, and the end result. I'm having trouble figuring out an approach to this that will allow new options and questions to be plugged in at a later stage without having things too coupled. The Observer pattern, or Laravel's events may be handy, but currently the sheer breadth of the calculator has me struggling to gather my thoughts and see a sensible implementation. Are there any patterns or OO approaches that may help? Thanks!

• Which architecture should I choose for this project?

  - by Jichao

  I have a project. The server which based on a phone PCI-board is responsible for received phone calls from the customer and then redirect the phone calls to the operators. I have decided to code the server using c++ programming language and qt framework because the PCI-board SDK's interface is c/c++ originated and for the sake of portability. The server need to send the information of the the customer to the operator while ringing the operator and the ui interface of the operator client should be browser-based. Now the key problem is how could the server notify the operator that there is a phone call for he/she. One architecture I have considered is like this, The operator browser client use ajax pooling the web server to check whether there is call to the client; the web server pooling the database server to check whether there is call; the desktop server(c++) wait for the phone calls and set the information in the database. The other operations such as hang up the phone call from the client, retransfer the phone call to the other operator also use this architecture. Then, is there any way other than pooling the server(js code setInterval('getDail', 1000)) to decide whether there is a call to the operator? Is this architecture feasible or should I use some terrific techniques that I do know such as web services,xml-rpc, soap???

• What is a good way to share internal helpers?

  - by toplel32

  All my projects share the same base library that I have build up over quite some time. It contains utilities and static helper classes to assist them where .NET doesn't exactly offer what I want. Originally all the helpers were written mainly to serve an internal purpose and it has to stay that way, but sometimes they prove very useful to other assemblies. Now making them public in a reliable way is more complicated than most would think, for example all methods that assume nullable types must now contain argument checking while not charging internal utilities with the price of doing so. The price might be negligible, but it is far from right. While refactoring, I have revised this case multiple times and I've come up with the following solutions so far: Have an internal and public class for each helper The internal class contains the actual code while the public class serves as an access point which does argument checking. Cons: The internal class requires a prefix to avoid ambiguity (the best presentation should be reserved for public types) It isn't possible to discriminate methods that don't need argument checking   Have one class that contains both internal and public members (as conventionally implemented in .NET framework). At first, this might sound like the best possible solution, but it has the same first unpleasant con as solution 1. Cons: Internal methods require a prefix to avoid ambiguity   Have an internal class which is implemented by the public class that overrides any members that require argument checking. Cons: Is non-static, atleast one instantiation is required. This doesn't really fit into the helper class idea, since it generally consists of independent fragments of code, it should not require instantiation. Non-static methods are also slower by a negligible degree, which doesn't really justify this option either. There is one general and unavoidable consequence, alot of maintenance is necessary because every internal member will require a public counterpart. A note on solution 1: The first consequence can be avoided by putting both classes in different namespaces, for example you can have the real helper in the root namespace and the public helper in a namespace called "Helpers".

• 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 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.

• Remember way back when we had a free decompiler?

  - by Justin Jones

  I, like probably so many of the rest of you, was mortified when Reflector was sold to RedGate. I knew where it was going. Suddenly you had to install it instead of just download and run it. I had a deep down feeling that one of the most useful tools in my arsenal was about to become a corporate product and no longer belong to the world of free tools. Sure enough it did. For a while now I’ve limped by without my favorite decompiler. This was made a little easier by the fact that you can now debug into the .net framework, but I still missed Reflector. JetBrains, makers of the superawesome and well worth the cost ReSharper (no it’s not free) have made their own decompiler that is comparable with Reflector, and it’s free. It’s still a corporate product, and JetBrains isn’t exactly known for making free software, but for now we have an option back on the table until some other industrious developer makes the next Reflector. dotPeek can be downloaded here.  http://www.jetbrains.com/decompiler/

• Python Web Applications: What is the way and the method to handle Registrations, Login-Logouts and Cookies? [on hold]

  - by Phil

  I am working on a simple Python web application for learning purposes. I have chosen a very minimalistic and simple framework. I have done a significant amount of research but I couldn't find a source clearly explaining what I need, which is as follows: I would like to learn more about: User registration User Log-ins User Log-outs User auto-logins I have successfully handled items 1 and 3 due to their simple nature. However, I am confused with item 2 (log-ins) and item 4 (auto-logins). When a user enters username and password, and after hashing with salts and matching it in the DB; What information should I store in the cookies in order to keep the user logged in during the session? Do I keep username+password but encrypt them? Both or just password? Do I keep username and a generated key matching their password? If I want the user to be able to auto-login (when they leave and come back to the web page), what information then is kept in the cookies? I don't want to use modules or libraries that handle these things automatically. I want to learn basics and why something is the way it is. I would also like to point out that I do not mind reading anything you might offer on the topic that explains hows and whys. Possibly with algorithm diagrams to show the process. Some information: I know about setting headers, cookies, encryption (up to some level, obviously not an expert!), request objects, SQLAlchemy etc. I don't want any data kept in a single web application server's store. I want multiple app-servers to be handle a user, and whatever needs to be kept on the server to be done with a Postgres/MySQL via SQLAlchemy (I think, this is called stateless?) Thank you.

• Building a complete program?

  - by Bob

  Reading books, watching videos, and reviewing tutorials is all very easy. Taking notes and actually learning the material may be slightly harder, but even then, anyone with a decent brain and a fair amount of interest, it's easy enough (not to mention, fun). The thing is, it doesn't really prepare you to write a full program or website. Let's say you're those teens (only in highschool, no true (college level) computer science or programming courses, and no real world experience), and you come out with Groupon. Or even Mark Zuckerburg, sure he was a genius, and he was a very capable programmer... but how? How do you recommend that people who are not necessarily new to programming, but new to programming real applications and real programmers go about developing it? What is the "development process" - especially for single programmers (or maybe 2-3 teens)? Also, as far as web development goes, what is the process? Was something like Facebook or Groupon written with a framework (like CodeIgniter or Zend for PHP)? Or do they develop their own frameworks? I'm not asking how to come up with a great idea, but how to implement great ideas in an effective way? Does anyone have advice? I've read a couple of books on both C and C++ (primarily the C Programming Language and the C++ Programming Language) and taken AP Computer Science (as well as read a few additional books on Java and OOP). I also have read a few tutorials on PHP (and CodeIgniter) and Python. But I'm still in highschool, and I'm technically not even old enough to work at an internship for a few more months.

• 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?

• Function calls to calls in windows api

  - by Apeee

  I am a beginner, and learning C, I find it hard to grasp the whole programming concept. so hopefully this would help to clear up some things along the way. When programming in windows, which is my aim for the time being, it is really hard for me to understand how windows communicate with the programs that run on it. A question i have been pondering about is how when you incorporate a function call which is in another memory location on the disk or memory(not a function you yourself wrote and is included in the compilation), especially the windows API, does the compiler know where the function location is so when the program is run it can call that function? For example, a very simple program that displays a window which reads hello world. You would have to call windows API functions to achieve such features as creating the window, its size, colors and so on... So basically what I am struggling to grasp is how the programs I write communicate with the platform, framework they are run on(generally windows for Windows API). Apart from clarification on this one above, i would love a resource that explains this concept further. Thanks for your time!
