  • Gilda Garretón, a Java Developer and Parallelism Computing Researcher

    - by Yolande
    In a new interview titled “Gilda Garretón, a Java Developer and Parallelism Computing Research,” Garretón shares her first-hand experience developing with Java and Java 7 for very large-scale integration (VLSI) of computer-aided design (CAD). Garretón gives an insightful overview of how Java is contributing to the parallelism development and to the Electric VLSI Design Systems, an open source VLSI CAD application used as a research platform for new CAD algorithms as well as the research flow for hardware test chips.  Garretón considers that parallelism programming is hard and complex, yet important developments are taking place.  "With the addition of the concurrent package in Java SE 6 and the Fork/Join feature in Java SE 7, developers have a chance to rely more on existing frameworks and dedicate more time to the essence of their parallel algorithms."

  • Professional iOS Development as a Backup Career [closed]

    - by New Coder
    I am a research chemist by day and I am a self-taught hobbyist iOS programmer by night. I am in the process of developing a moderately complex iOS app and hope to launch it within a month or two. I love everything about iOS development (and programming in general). I want to know if iOS development could become a backup career for me if I loose my job. My question: Let's say I had a couple of apps in the app store, a solid foundation in objective-C and the apple frameworks and basic knowledge on network integrated apps. Without a formal CS degree, what other experience/knowledge would I need to land a job as a professional iOS developer? Forgive me if this question is out of bounds for this forum. If it is, suggestions on where to post such a question would be appreciated.

  • I don't really understand "Backend/Serverside" when it comes to web-development?

    - by Mercfh
    In the Web development world, what exactly do backend/server-side programmers do? I guess I don't really understand the whole concept. I've done the HTML/CSS layouts and website design and a little bit of SQL with PHP (still enhancing my skills, it's more of a side project for me). I've also done a small amount of JavaScript/JQuery. But I don't understand the "backend" work, such as the scripting languages (Rails/Python/etc) and such. What exactly do you "do" with them? Are there any books on the subject? I'm not even sure what it means. Is it kinda like what Web Application Frameworks do? Or not so much?

  • In Scrum, should tasks such as development environment set-up and capability development be managed as subtasks within actual user stories?

    - by Asim Ghaffar
    Sometimes in projects we need to spend time on tasks such as: exploring alternate frameworks and tools learning the framework and tools selected for the project setting up the servers and project infrastructure (version control, build environments, databases, etc) If we are using User Stories, where should all this work go? One option is to make them all part of first user story (e.g. make the homepage for application). Another option is to do a spike for these tasks. A third option is to make task part of an Issue/Impediment (e.g. development environment not selected yet) rather than a user Story.

  • Compiler Dependencies [closed]

    - by asghar ashgari
    I'm a newbie researcher who's passion is programming languages (Web era). I'm wondering why all the Web frameworks and Web-based general purposes languages, have a huge number of dependencies when you want to install and then use (e.g., extend, alternate, etc.) their compilers. For example, Ruby on Rails or Scala. If I want to download their source code, and try to build it again, to me at least, feels like a can of worms. I have a MAC, so I need to install MACports, then update my XCode, then get the compiler source code that has bunch of other dependencies, then its hard to set things up; just to see the installed open-source compiler works fine.

  • Web framework for IPad and common desktop browsers?

    - by Chris
    We are developing a web-based, commercial point-of-sale application. We'd like the same web site to work well on an Ipad as well a desktop browsers. We're looking for a web framework that makes the site look good on an IPad, but also makes the site work well in a desktop browser such as Chrome, IE, or Firefox on Windows or a Mac. I found quite a few at 18 Mobile Frameworks and Development Tools for Creating iPhone Apps Most of them, such as JQTouch, help a web site look and act more like a native IPhone application but they don't emphasize the cross platform/browser experience. The exception seems to be Sproutcore, which seems to be a full-fledged javascript MVC application framework. I did have trouble getting some of the demos to work under Chrome, but what did work looks good. What framework(s) have you actually used to develop web sites to work on an Ipad and desktop browser? If you didn't use a framework, how did you get it to work well under both environments?

  • AJI Report #18 | Patrick Delancy On Code Smells and Anti-Patterns

    - by Jeff Julian
    Patrick Delancy, the first person we interviewed on the AJI Report, is joining us again for Episode 18. This time around Patrick explains what Code Smells and Anti-patterns are and how developers can learn from these issues in their code. Patrick takes the approach of addressing your code in his presentations instead of pointing fingers at others. We spend a lot of time talking about how to address a developer with bad practices in place that would show up on the radar as a Code Smell or Anti-Pattern without making them feel inferior. Patrick also list out a few open-source frameworks that use good patterns and practices as well as how he continues his education through interacting with other developers.

  • What have we lost from computers 20 years ago

    - by Martin Beckett
    Following the theme of - I can't believe computers used floppy disks and did you have debuggers 20 years ago - questions (and because even putting my age in hex I don't look young anymore). What have we lost from computers 20years ago? VMS versioning file system. Make a mistake, no problem myprog.cpp;5 is still there. Home computers that powered up to give you a wordprocessor or a basic prompt in <0.5sec User ports, serial ports and ADCs that you could control things with - without an arduino APIs that actually did what they said (even DOS interrupts), without having to guess and experiment your way through layers of frameworks.

  • Java EE/GlassFish Adoption Story by Kerry Wilson/Vanderbilt University

    - by reza_rahman
    Kerry Wilson is a Software Engineer at the Vanderbilt University Medical Center. He served in a consultant role to design a lightweight systems integration solution for the next generation Foundations Recovery Network using GlassFish, Java EE 6, JPA, @Scheduled EJBs, CDI, JAX-RS and JSF. He shared his story at the JavaOne 2013 Sunday GlassFish community event - check out the video below: Kerry outlined some of the details of the implementation and emphasized the fact that Java EE can be a great solution for applications that are considered small/lightweight. He mentioned the productivity gains through the modern Java EE programming model centered on annotations, POJOs and zero-configuration - comparing it with competing frameworks that aim towards similar productivity for lightweight applications. Kerry also stressed the quality of the excellent NetBeans integration with GlassFish and the need for community self-support in free, non-commercial open source projects like GlassFish. You can check out the details of his story on the GlassFish stories blog. Do you have a Java EE/GlassFish adoption story to share? Let us know and we will highlight it for the community.

  • Web Camps by Microsoft

    - by Shaun
    Just knew from Wang Tao that Microsoft will launch the Web Camp event in many cities to share their technologies and experience on web application building. The topics of this Web Camps would focus on ASP.NET, jQuery and Entity Frameworks and how to build a cool web application based on them which I’m very interesting. And another reason is that, it’s FREE.   Please have the detail information and register at http://www.webcamps.ms/, which is built on Windows Azure. And the speaker in Beijing would be Scott Hanselam and James Senior – WOW!   Hope this helps, Shaun   All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  • Would knowing Python help with creating iPhone applications?

    - by Josh
    Here is what the apple site says: With Snow Leopard, Mac OS X makes it easy to use scripting languages as full application development tools. Snow Leopard ships with support for the RubyCocoa Bridge and the PyObjC bridge. These two bridges give developers access not only to system APIs, but to Cocoa frameworks such as AppKit and Core Data, enabling you to build fully native Mac OS X applications in Ruby or Python. The RubyCocoa and PyObjC bridges allow you to freely mix code written in Objective-C with code written in the scripting language. You can quickly build prototypes and then optimise by implementing performance-critical pieces in Objective-C. How could Python help in this case?

  • Invoke WCF rest service razor mvc 4

    - by Raj Esh
    I have been using jQuery to access my REST based wcf service which does not export the meta information. Using ajax, i could populate data into controls. I need guidance and directions as to how i can use these Rest service in my controller. I can't add Service reference to my MVC 4 project since my WCF rest does not to expose Metadata. Should i use UNITY? or any other DI frameworks?. Any sample would be of great help.

  • Confused about ASP.NET Ajax, jQuery and JavaScript

    - by Mr.Y
    Yesterday, I read couple of chapters on ASP.NET Ajax and jQuery from my ASP.NET 4 book and I found those frameworks pretty interesting and decide to learn more about them. Today, I borrowed some books from library on Ajax and JavaScript. It seems ASP.NET Ajax is different from Ajax and jQuery seems like the "new" JavaScript. Does it mean that I can skip JavaScript and learn jQuery directly? On the other hand, the non-ASP.NET Ajax book I borrowed seems to apply to the client side web programming only and looks quite different from what I learned from ASP.NET Ajax. If I'm an ASP.NET developer, I guess I should stick with ASP.NET Ajax instead of client side Ajax right? What about PHP? Is there a "PHP Ajax" similar to ASP.NET Ajax? It's not that I'm lazy to learn other tools, but I just want to focus on the right ones.

  • Authorizing a module in a framework

    - by Devon
    I've been studying PHP frameworks and I've been looking for how you would go about properly authorizing a module for classes, methods, and database actions. For example, lets say I want a framework that includes different modules from different programmers: Some core class may require special access, not all modules should have access to every core class unless authorized to. I do not want one module to be able to call another module's class/method if it is not supposed to be able to. I also don't want a security flaw in one module to be able to affect another module's database tables. I suppose an easy way to go about this is have a database table for authorization to consult, but I doubt that is the best way to go about this. I'd appreciate any advice or pointing me in the right direction for some reading.

  • HTML5 mobile game development vs. native game apps

    - by Vic Szpilman
    What is the current state of game engines, frameworks, libraries and conversions related to the HTML5 set of technologies (including CSS3 and JavaScript libraries such as RaphaelJS, Impact, gameQuery); and how does the best of that compare with developing a native app (especially for iOS and Android)? Especially in terms of performance, visuals and getting that "native feel". Thoughts on solutions such as Appcelerator and Corona SDK are also appreciated. In regards to Unity3D, is it possible to develop in it and still have the game be playable on a browser (such as current releases of Chrome or Firefox, at least) without any dependencies or having the user install anything (no unity web player). What I'm looking for is how to develop in web standards as to reach the maximum number of platforms (including outside mobile) while still retaining a native experience for mobile without having to implement the game anew for iOS and Android.

  • Is windows a "second class citizen" in the django community?

    - by Daniel Upton
    I'm currently doing R&D for a web application which we plan to host ourselves initially and then allow customers to self host. My task has been evaluating web frameworks to see which would give us the biggest productivity initially and ease of maintence while also allowing us to easily support deployment to customer controlled environments. Our team has experience with ASP.NET (MVC and Webforms) and Ruby on Rails. Our experience with rails is that windows deployment is a very taboo subject and any questions on IRC or SO are met with knee jerk "why not linux" responses.. However in this case our target market may be running windows or linux servers. Is this also the case in django land? Is it possible with rubbish performance? Is it possible with lost of pain? Is it seen as reasonable and not treated as a completely stupid idea for not wanting to run linux?

  • Why isn't Java more widely used for game development?

    - by Anto
    I'm not a game developer or anything, but I know that Java is not very widely used for game development. Java should be fast enough for most games, so where's the catch? I can think of some reasons: Lack of game developers with expertice in Java Lack of good game development frameworks Programmers don't want to accept Java as a games programming language. Most only accept C++ as that? No support for game consoles (though the PC market still exists) It could of course be something else. Could someone who knows the business better than me explain why Java isn't getting momentum when it comes to game development?

  • Why do people hesitate using Python 3?

    - by Ham
    Python 3 has been released in December 2008. A lot of time has passed since then but still today many developers hesitate using Python 3. Even popular frameworks like Django are not compatible with Python 3 yet but still rely on Python 2. Sure, Python 3 has some incompatibilities to Python 2 and some people need to rely on backwards-compatibility. But hasn't Python 3 been around long enough now for most projects to switch or start with Python 3? Having two competiting versions has so many drawbacks; two branches need to be maintained, confusion for learners and so on, so why is there such a big hesitation throughout the Python community in switching to Python 3?

  • Platforms for sharing content and expertise

    - by Thomas
    Are there any platforms / sites where people can share expertise in game development and where you can share (either payed or free) digital content (like images, sounds, animations but also frameworks or libraries) to be used in games? I'd also like the possibility to contact users and request specific pieces of content. I'd like to start out as an indie developer and have programming skills but I lack the experience and time to create ingame artwork and sound. Is there any site where I could locate other people (artists mostly) who would want to work on a game for free? I know I can get most technical questions answered on this site and I have some contacts but I'm affraid this won't be enough.

  • Is there any one standard framework for developing Python GUI apps.?

    - by RPK
    There are so many frameworks for writing GUI application using Python. But is there any one key standard framework? For example we have a bundle of .NET/C# on Visual Studio. I am thinking in other perspectives also. In future if I give an interview for a Python programmer job, which GUI framework will be considered? I also wonder, there is no IDE that integrates the GUI and Python language. Choice of flavor is good but over-choice becomes a distraction.

  • data maintenance/migrations in image based sytems

    - by User
    Web applications usually have a database. The code and the database work hand in hand together. Therefore Frameworks like Ruby on Rails and Django create migration files Sure there are also servers written in Self or Smalltalk or other image-based systems that face the same problem: Code is not written on the server but in a separate image of the programmer. How do these systems deal with a changing schema, changing classes/prototypes. Which way do the migrations go? Example: What is the process of a new attribute going from programmer's idea to the server code and all objects? I found the Gemstone/S manual chapter 8 but it does not really talk about the process of shipping code to the server.

  • Where should I draw the line between unit tests and integration tests? Should they be separate?

    - by Earlz
    I have a small MVC framework I've been working on. It's code base definitely isn't big, but it's not longer just a couple of classes. I finally decided to take the plunge and start writing tests for it(yes, I know I should've been doing that all along, but it's API was super unstable up until now) Anyway, my plan is to make it extremely easy to test, including integration tests. An example integration test would go something along these lines: Fake HTTP request object - MVC framework - HTTP response object - check the response is correct Because this is all doable without any state or special tools(browser automation etc), I could actually do this with ease with regular unit test frameworks(I use NUnit). Now the big question. Where exactly should I draw the line between unit tests and integration tests? Should I only test one class at a time(as much as possible) with unit tests? Also, should integration tests be placed in the same testing project as my unit testing project?
