  • Java web UI framework like ASP.NET MVC?

    - by Ethel Evans
    I'm doing some web apps for personal projects that might be shared out with my friends. I'm trying to use skills that will help me at work, but don't have $$ to spend on Visual Studio right now and don't want to try to cobble something together with Express Editions. Since I've been sort of wanting to bring my Java skills up to date and the main skills I want to work on are design and architecture skills, this isn't a big deal - except that I have no idea how to track down the right UI framework. I know I want something based on MVC, to get more practice with frameworks for that design pattern (we're using ASP .NET MVC2 at work). The UIs that I'll be making will be pretty simple - data entry, buttons, text, images. They will need AJAX. Any thoughts about which frameworks to look at? I'll be watching the comments, if anyone wants additional clarification on what I'm looking for.

  • Should I put an app I wrote on my résumé even if it has low ratings?

    - by charliehorse55
    Last summer I wrote an iPhone app for the Toronto Film Festival. The development was pretty rushed, and the design goals were changed multiple times. In particular, the central film list view controller was redesigned three times in the week before launch. I forgot to update one of my functions to match the changed design, and the app shipped with a serious bug. While the app was fairly popular, this bug crippled the app and it got a lot of poor reviews. I fixed the bug as soon as I got a crash report, but it got stuck in the iTunes review process for the duration of the film festival. Should I put this app on my résumé? The app has poor ratings and most of the reviews mention crashes, but it's also the only work experience I have. Additionally, how should I approach this topic in an interview? Here is the iTunes link for the app: https://itunes.apple.com/ca/app/official-tiff/id550151899?mt=8

  • I want to master ASP.NET - What concepts should I focus on/What concepts do you most value?

    - by Josh
    I start a job this summer doing work in ASP.NET 4 (C#). I plan on working with some legacy code as well as MVC. I want to get a running start. I have good understanding of HTML/CSS/Javascript, and pretty good understanding of C# itself, Design principles, Design Patterns, and understand masterpages, basic MVC2, and code behinds for web forms. In your opinion what aspects of ASP.NET are the most important to master for web applications? What do you value most in your usage of ASP.NET? Do you have a recommendation for understanding the internals of ASP.NET itself?

  • Google Open-Sources Their Book Scanner

    - by Jason Fitzpatrick
    Google has released the hardware and software source for their high speed/non-destructive book scanner–If you’re looking to scan a large volume of books, save yourself the design work and check out the Linear Book Scanner project. The design is pretty slick; the scanner uses vacuum pressure to automatically turn the pages as it works.

  • Hard Copies VS Soft Copies

    - by Garet Claborn
    Where do you draw the line and say, "OK, I'm actually going to print out this piece of code, spec, formula, or other info and carry it around but these pieces can stay on disk." Well, more importantly why do you draw the line there? I've encountered this a number of times and have some sort of vague conceptions beyond "oh now I'm REALLY stuck, better print this out." I've also found some quicksheets of basic specs to be handy. Really though, I have no particular logic behind what is useful to physically have available in the design and development process. I have a great pile of 'stuff' papers that seemed at least partially relevant at the time, but I only really use about a third of them ever and often end up wishing I had different info on hand. Edit: So this is what I'm hearing in a nutshell: Major parts of the design pattern Common, fairly static and prominently useful code (reference or specs) Some representation of data useful in collaborating or sharing with team Extreme cases of tough problem solving Overwhelmingly,almost never print anything.

  • ASP.NET Web Forms is bad, or what am I missing?

    - by iveqy
    Being a PHP guy myself I recently had to write a spider to an asp.net site. I was really surprised by the different approach to ajax and form-handling. For example, in the PHP sites I've worked with, a deletion of a database entry would be something like: GET delete.php?id=&confirm=yes and get a "success" back in some form (in the ajax case, probably a json reply). In this asp.net application you would instead post a form, including all inputs on the page, with a huge __VIEWSTATE and __EVENTVALIDATION. This would be more than 10 times as big as above. The reply would be the complete side again, with a footer containing some structured data for javascript to parse and display the result. Again, the whole page is sent, and then throwed away(?) since it's already displayed. Why not just send the footer with the data to parse (it's not json nor xml but a | separated list). I really can't see why you would design a system that way. Usually you've a fast client, and a somewhat fast server but a really slow connection. Why not keep the datatransfer to a minimum? Why those huge __VIEWSTATE and __EVENTVALIDATION? It seems that everything is done way to chatty and way to complicated. I really can't see the point and that usually means that I'm missing something. So please tell me, what are the reasons for this design and what benefits (and weaknesses) does it have? (Yes I know that __VIEWSTATE is used to tell what type of form-konfiguration should be sent back to the server. But WHY is this needed?) Please keep this discussion strictly technical and avoid flamewars. Update: Please excuse the somewhat rantish question. I tried to explain my view to be able to get a better answer. I am not saying that asp.net is bad, I am saying that I don't understand the meaning of those concepts. Usually that means that I've things to learn instead of the concepts beeing wrong. I appreciate the explanations about that "you don't have to do this way in asp.net", I'll read up on MVC and other .net technologies. However, there most be a reason for this site (the one I referred to) to be written the way it is. It's written by professionals for a big organisation with far more experience than what I've. Any explanation about their (possible) design choice would be welcome.

  • Integrating Azure ServiceBus and SharePoint 2010

    - by Sahil Malik
    SharePoint 2010 Training: more information My new article is finally online. I had been waiting for this for a while. The thing is, AppFabric became .NET 4, and left SharePoint 2010 behind. But fear not, we have REST API. But that brings up interesting challenges of how we can integrate Azure Service Bus with SharePoint 2010 (yes 2010, not vNext – I’m not giving NDA information out you fool), the design patterns you can use, figuring out challenging issues like security, sessions, and just app design patterns instead. Well, I hope you like my next article, SharePoint Applied: Azure ServiceBus and SharePoint 2010 Enjoy! Read full article ....

  • Dealing with coworkers when developing, need advice [closed]

    - by Yippie-Kai-Yay
    I developed our current project architecture and started developing it on my own (reaching something like, revision 40). We're developing a simple subway routing framework and my design seemed to be done extremely well - several main models, corresponding views, main logic and data structures were modeled "as they should be" and fully separated from rendering, algorithmic part was also implemented apart from the main models and had a minor number of intersection points. I would call that design scalable, customizable, easy-to-implement, interacting mostly based on the "black box interaction" and, well, very nice. Now, what was done: I started some implementations of the corresponding interfaces, ported some convenient libraries and wrote implementation stubs for some application parts. I had the document describing coding style and examples of that coding style usage (my own written code). I forced the usage of more or less modern C++ development techniques, including no-delete code (wrapped via smart pointers) and etc. I documented the purpose of concrete interface implementations and how they should be used. Unit tests (mostly, integration tests, because there wasn't a lot of "actual" code) and a set of mocks for all the core abstractions. I was absent for 12 days. What do we have now (the project was developed by 4 other members of the team): 3 different coding styles all over the project (I guess, two of them agreed to use the same style :), same applies to the naming of our abstractions (e.g CommonPathData.h, SubwaySchemeStructures.h), which are basically headers declaring some data structures. Absolute lack of documentation for the recently implemented parts. What I could recently call a single-purpose-abstraction now handles at least 2 different types of events, has tight coupling with other parts and so on. Half of the used interfaces now contain member variables (sic!). Raw pointer usage almost everywhere. Unit tests disabled, because "(Rev.57) They are unnecessary for this project". ... (that's probably not everything). Commit history shows that my design was interpreted as an overkill and people started combining it with personal bicycles and reimplemented wheels and then had problems integrating code chunks. Now - the project still does only a small amount of what it has to do, we have severe integration problems, I assume some memory leaks. Is there anything possible to do in this case? I do realize that all my efforts didn't have any benefit, but the deadline is pretty soon and we have to do something. Did someone have a similar situation? Basically I thought that a good (well, I did everything that I could) start for the project would probably lead to something nice, however, I understand that I'm wrong. Any advice would be appreciated, sorry for my bad english.

  • Can an object oriented program be seen as a Finite State Machine?

    - by Peretz
    This might be a philosophical/fundamental question, but I just want to clarify it. In my understanding a Finite State Machine is a way of modeling a system in which the system's output will not only depend on the current inputs, but also the current state of the system. Additionally, as the name suggests it, a finite state machine can be segmented in a finite N number of states with its respective state and behavior. If this is correct, shouldn't every single object with data and function members be a state in our object oriented model, making any object oriented design a finite state machine? If that is not the interpretation of a FSM in object design, what exactly people mean when they implement a FSM in software? am I missing something? Thanks

  • Drag and drop fearture for a website

    - by gpuguy
    I have to design a website which will have drag and drop features for creating an e-card. So you select items from a tool box and drag and drop this item on the card area. Once you have completed the design you can publish the e-card on the web by clicking "Save and publish" button. What are the possible technologies for implementing this feature? The requirement is that the application should not degrade the performance of the website, and should not take much time in publishing once the user click "Save and publish" button.

  • Our Favorite Highlights from OpenWorld 2012

    - by Kathy.Miedema
    By Kathy Miedema and Misha Vaughan, Oracle Applications User Experience The Oracle Applications User Experience (UX) team’s activities around OpenWorld expand every year, but this year we certainly raised the bar.   Members of our team helped deliver three, separate, all-day training events in the week prior to OpenWorld. Our Fusion User Experience Advocates (FXA) and Applications UX Sales Ambassadors (SAMBA) have all-new material around the Oracle user experience to deliver at conferences in the coming year - Fusion Applications design patterns, mobile design patterns, and the new face of Fusion. We also delivered a hands-on workshop sharing user experience tools for our customers that is designed to answer this question: "If I have no UX staff, what do I do?" We also spent the weeks just before OpenWorld preparing to talk about the new face of Fusion Applications, a greatly simplified entry experience into Fusion Applications for self-service users, CRM users, and IT managers who want to change the look and feel quickly. Special thanks to Oracle ACE Director Floyd Teter for the first mention of our project.Jeremy Ashley, VP, Oracle Applications User Experience Customers may have seen one of the many OpenWorld session demos of the new face of Fusion, which will be available with Fusion Applications soon. It was shown in sessions by Oracle's Chris Leone, Anthony Lye, and our own Vice President, Jeremy Ashley, among others.   Leone reinforced the importance of user experience as one of three main design principles for Fusion Applications, emphasizing that Fusion was designed from the beginning to be intelligent, social, and mobile. User experience highlights of the new face of Fusion, he said, included the need for "zero training," and he called the experience "easy to use." He added that deploying it for HCM self-service would be effortless.  Customers take part in a usability lab tour during OpenWorld 2012. Customers also may have seen the new face of Fusion on the demogrounds or during one of our teams' chartered lab tours at the end of the week. We tested other new designs at our on-site lab in the Intercontinental Hotel, next to Moscone West. Applications User Experience team members show eye-tracking and mobile demos at OOW. We were also excited to kick off new branches of the Oracle Usability Advisory Board, which now has groups in Latin America and the Middle East, in addition to North America and EMEA.   And we were pleasantly surprised by the interest in one of our latest research projects, Oracle Voice, which is designed to enable faster data input for on-the-go users. We offer a big thank-you to the Nuance demopod for sharing the demo with OpenWorld attendees.  For more information on our program and products like the new face of Fusion, please comment below.

  • Generation 4 Modular Data Center

    - by kaleidoscope
    Microsoft’s launched Generation 4 Modular Data Center design at the PDC 09 - The 20-foot container built on container-based model. Microsoft says the use of server-packed containers – known as Pre-Assembled Components (PACs) – will allow it to slash the cost of building its new data centers. Completely optimized for outdoor use, with a design that relies upon fresh air (”free cooling”) rather than air conditioning. Its exterior is designed to draw fresh air into the cold aisle and expel hot air from the rear of the hot aisle.

  • In this context with views in a tree, which class should perform the task?

    - by Jhonny 8
    Imagine that I have this context: A main view containing a table containing some cells. Each one of them with their own controller and view files. In the main view, I have an object "Person", with 3 different IDs. Depending on certain conditions (let say, time of the day), I have to choose one of them and display it in the cell. My question is, should the main view pass the whole object to the table, and this one to the cell, and the cell will calculate the ID that it will be shown? or, The main view calculates this parameter, and send the result to the table and this to the cell? Is a question focused on OO design, which one of this approaches is more suitable in an OO design and why?

  • User eXperience

    - by Daniel Moth
    The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

  • How to improve quality of software

    - by hariharan
    Last week in our organization, we triggered a topic related to different ways of improving the quality of software (both technical as well as functional related topics). Since i am a technical person, i suggested following ideas, Use case based detailed design document – Both technical as well as functional specification should be well organized according to use case requirement. Design patterns – Will help developers to adopt common approach irrespective of technologies. Analyze and implement new technologies – Helps to improve the performance as well as the security of the application. As I am not a well experienced technical candidate , i am unable to provide other solutions. If any suggestions or topics related to this (including testing, functional requirement), please post your valuable comments.

  • web services, J2EE, spring, DB integration project ideas- maybe data mining related?

    - by sj88
    Hey guys, I am a graduate CS student (Data mining and machine learning) and have a good exposure to core JAVA (3 years). I have read up a bunch of stuff on Design patterns J2EE Web services( soap and rest) spring and hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff (over my free time of corse) to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + svn, maven). Any good project ideas would be really appreciated. I just wanna build this stuff to learn so I dont really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus (fits with my research) but absolutly not necesary (since this project is more to learn to do large scale software developement)

  • VS2010 crashes when opening a vsp generated using VS 2012

    - by Tarun Arora
    I recently profiled some web applications using Visual Studio 2012, a vsp (Visual Studio Profile) file was generated as a result of the profiling session. I could successfully open the vsp file in Visual Studio 2012 as expected but when I tried to open the vsp file in Visual Studio 2010 the VS2010 IDE crashed. As a responsible citizen I raised bug # 762202 on Microsoft Connect site using the Microsoft Visual Studio 2012 Feedback Client. Note – In case you didn’t already know, VSP generated in Visual Studio 2012 is not backward compatible. Please refer below for the steps to reproduce the issue and the resolution of the connect bug. 1. Behaviour and Steps to Reproduce the Issue Description I have generated a vsp file by using the Visual Studio 2012 Standalone profiler. When I try and open the vsp file in Visual Studio 2010 the IDE crashes. I understand that a vsp generated by using VS 2012 cannot be opened in VS 2010, but the IDE crashing is not the behaviour I would expect to see. Steps to Reproduce the Issue 1. Pick up the Stand lone profiler from the VS 2012 installation media. The folder has both x 64 and x86 installer, since the machine I am using is x64 bit. I have installed the x64 version of the standalone profiler. 2. I have configured the system path by setting the 'environment variable' path to where the profiler is installed. In my case this is, C:\Program Files (x86)\Microsoft Visual Studio 11.0\Team Tools\Performance Tools 3. Created a new environment variable _NT_SYMBOL_PATH and set its value to CACHE*C:\SYMBOLSCACHE;SRV*C:\SYMBOLSCACHE*HTTP://MSDL.MICROSOFT.COM/DOWNLOAD/SYMBOLS;\\FOO\BUILD1234 4. Open up CMD as an administrator and run 'VSPerfASPNETCmd /tip http://localhost:56180/ /o:C:\Temp\SampleEISK.vsp' 5. This generates the following message on the cmd       Microsoft (R) VSPerf ASP.NET Command, Version 11.0.0.0     Copyright (C) Microsoft Corporation. All rights reserved.     Configuring and attaching to ASP.NET process. Please wait.     Setting up profiling environment.     Starting monitor.     Launching ASP.NET service.     Attaching Monitor to process.     Launching Internet Explorer.     The profiler is attached to ASP.net. Please run your application scenario now.     Press Enter to stop data collection...   6. I perform certain actions and then I come back to the cmd and hit enter to shut down the profiling. Once I do this, the following message is written to the cmd, Press Enter to stop data collection... Profiling now shut down. Report file "C:\Temp\SampleEISK.vsp" was generated. Running VsPerfReport, packing symbols into the .VSP. Shutting down profiling and restarting ASP.NET. Please wait. Restarting w3wp.exe.   7. I look in the C:\Temp folder and I can see the SampleEISK.vsp file generated. I can successfully open this file in Visual Studio 2012. 8. When I am trying to open the vsp file in VS 2010 the VS 2010 IDE crashes. Kaboooom! What I would expect to happen I expect to receive a message "VS 2010 does not support the vsp file generated by VS 2012". What actually happened The VS 2010 IDE crashed 2. Resolution This is a valid bug! However, there isn’t much value in releasing a hotfix for this issue. Refer below to the resolution provided by the Visual Studio Profiler Team.  Thank you for taking the time to report this issue. We completely agree that Visual Studio 2010 should not crash. However in this particular case this is not a bug we are going to retroactively release a fix to 2010 for at this point. Given that a fix would not unblock the scenario of opening a 2012 created file on Visual Studio 2010, and there is not an active update channel for Visual Studio 2010 other than manually locating and installing hot fixes, we will not be fixing this particular issue. Best Regards, Visual Studio Profiler Team   Though it would be great to improve the behaviour however, this is not a defect that would stop you from progressing in any way. It’s important to note however that VSP files generated by Visual Studio 2012 are not backward compatible so you should refrain from opening these files in Visual Studio 2010.

  • Constraints while designing the Java generics

    - by Andrea
    Java generics look quite different from those available in Scala, although both were designed by Martin Odersky. From my point of view, the design of generics in Java is worse, for instance: there is no possibility to specify variance one can get around the previous limitation by using wildcards, but this means the burden of specifying variance goes on the caller instead of the library designer one cannot use a type constructor in generics What were the constraints in Java that forced Odersky to design this mechanism for generics instead of the more flexible one he devised for Scala? Was he just savvier a few years later or there were actual limitations due to Java?

  • 3D Modeling Software for Programmer [closed]

    - by Pathachiever11
    I've recently learned how to make games for Unity3d, and now I want to start making games! I can't wait to start! However, before I can make 3D games, I need to learn 3D modeling for character design, level design, and some animation. What is the easiest 3D modeling software, compatible with Unity3d? I do not want to spend too much time learning the software. From what I've heard, Blender is a bit complicated to use. Maya and 3dsMax seem very powerful. Could someone point me in the right direction? I don't want to spend a lot of time learning. I know its not that easy, but you guys have experience, you guys probably know out of all which one is easier and powerful. Could you recommend a software? Many Thanks!

  • How to model interentity membership in entity-component architecture?

    - by croxis
    I'm falling in love with simple grace of entity-component design, although I still have issues breaking from MVC and OOP practices. Some of my game entities have membership relationships with each other (ex: a player is a member of a city, a city is a member of a nation), and I am unsure on the best way to implement it. My initial reaction is to have a a MemberOfCity component that points to the appropriate city component, but components are suppose to have no references to each other. My other option is to have a System do it, but that would require the system to persist data outside of a component. Is there a clean way to do this in an entity-component design, or am I trying to use a hammer on a screw and should use a hybrid/another approach?
