  • jQuery mobile List-View is not working after adding some jquery code [closed]

    - by Kaidul Islam Sazal
    I am using jquery mobile and I have an array makeArrayin jquery and I have created few listview by the values of the array.Everything works fine.But the jquery mobile list-view style is not shown. Rather it is shown an ordinary list view. This is my code: $(document).ready(function(){ var url = "inventory/inventory.json"; var makeArray = new Array(); $.getJSON(url, function(data){ $.each(data, function(index, item){ if(($.inArray(item.make, makeArray)) == -1){ makeArray.push(item.make); $('.upper_case') .append('<li data-icon="list-arrow"> <a href="trade_form.php?='+ item.make +'"><img src="images/car_logo/buick.png" class="ui-li-thumb"/>' + item.make + '</a></li>'); } }); }); });

  • How to analyze a scenario where a bug didn't get caught and adjust development workflow to prevent similar errors

    - by durron597
    I had a bug that was really difficult to track down, because all the unit tests were green, but the production application didn't work properly. Here's what happened: I had a filter class that set my application to ignore data that was not in some specified time windows. The unit test, which seemed thorough to me, turned green. Additionally, my integration tests also produced results as expected. Production, however, did not work. As a result of the first two bullets, this problem was very difficult to find. It turned out the problem was that my test dates were using my time zone (America/Chicago) but the production data was providing dates in UTC, which I did not realize, and the logic for the filter wasn't correct for UTC dates. (I was using joda time DateTime objects). Where did my workflow break down? Did I fail to produce a spec that specified that the logic needed to handle dates in any time zone? Did I fail to thoroughly consider all cases at the unit test level? Did I fail to insure the integration test was sufficiently similar to production? Other? What changes can I make to my workflow to better prevent this sort of mistake in the future? How can I more effectively debug a problem when there is an issue in production but not in testing?

  • How to choose the right web development language for my app without much programming experience?

    - by twinbornJoint
    I have my own idea for a web application, and I am not a programmer. The application will work similar to Facebook and Twitter, profiles and feeds. I have learned some computer science theory, all the way up to OOP, but have no practical experience. Without any experience, is there a way I can evaluate the different language and platform choices available to me? What kind of things should I be looking at? Ease of setup? How many followers it has? How can I evaluate whether a language will have the capabilities I need?

  • Broad topics needed for teaching game development

    - by livingtech
    I am going to be doing a presentation on game development to an iPhone user group in the near(ish) future. My audience are iPhone developers, but not necessarily very experienced ones, and this is meant to be an introduction. My question is, what broad topics are needed to understand game development? I acknowledge that this is fairly subjective, but I really am hoping for a comprehensive list of high-level topics that apply to a broad enough swath of games that anyone interested in the topic SHOULD know about them. I would be ecstatic with some pointers to any resources that attempt to make a list such as this this. (I have looked, but my google-fu is failing me tonight.) Here's what I have so far: The Game Loop a sub-note about event driven games 2D Animation sprites/texture maps 3D Animation importance of frameworks modeling software Particles and particle effects hit detection AI Obviously I will not be covering all these topics with any depth, more like simply defining them so that after my talk, the audience will (hopefully) be able to wrap their heads around how any given game might be developed. What am I missing?

  • Is it common for a development position to be extremely mundane and not challenging at all? [closed]

    - by Kim Jong Woo
    Hi guys so I am working at this company as a web developer but after 1 week of working here, I realize the stuff I am doing seem to be very easy stuff compared to what my peers who have been around for longer are doing. I am way ahead of my schedule and finish my projects early but it's because the work is not at all hard or problem solving involved. So I am puzzled why I would be thanked over doing such menial tasks. Is this normal? This is driving me nuts, I ask to be given more work and I do get it and still finish it quickly and accurately. Now I am having this paranoia that they are just conspiring to use me for a short period of time and terminate me. Am I going too far with this? I keep losing sleep over this. On days when I have a full load of work to complete, this uneasiness goes away but so far I feel like I am not being allowed to pursue what I thought I would do like solving and designing solutions. A lot of it doesn't require any thinking, just cleaning up other people's code and closing bug tickets.

  • How to test issues in a local development environment that can only be introduced by clustering in production?

    - by Brian Reindel
    We recently clustered an application, and it came to light that because of how we're doing SSL offloading via the load balancer in production it didn't work right. I had to mimic this functionality on my local machine by SSL offloading Apache with a proxy, but it still isn't a 1-to-1 comparison. Similar issues can arise when dealing with stateful applications and sticky sessions. What would be the industry standard for testing this kind of production "black box" scenario in a local environment, especially as it relates to clustering?

  • Healthcare Mobile Database Synchronization Demonstration

    - by Jim Connors
    Like many of you, I learn best by getting my hands dirty.  When confronted with the task of understanding a new set of products and technologies and figuring out how they might apply to a vertical industry like healthcare, I set out to create a demonstration.  The video that follows aims to show how the Oracle embedded software portfolio can be applied to a healthcare application.  The demonstration utilizes among others, Java SE Embedded, Berkeley DB, Apache Tomcat, Oracle 11gR2 and Oracle Database Mobile Server. Eric Jensen gives a great critique and description of the demo here.  To sum it up, we aim to show how live medical data can be collected on a medical device, stored in a local database, synchronized to a master database and furthermore propagated to a mobile phone (Android) application.  Come take a look!

  • How to shift development culture from tech fetish to focusing on simplicity and getting things done?

    - by Serge
    Looking for ways to switch team/individual culture from chasing latest fads, patterns, and all kinds of best practices to focusing on finding quickest and simplest solutions and shipping features. My definition of "tech fetish": Chasing latest fads, applying new technologies and best practices without considering product/project impact, focusing on micro optimization, creating platforms and frameworks instead of finding simple and quick ways to ship product features. Few examples of culture differences: From "Spent a day on trying to map database query with five complex joins in NHibernate" to "Wrote a SQL query and used DataReader to pull data in" From "Wrote super-fast JSON parser in C++" to "Used Python to parse JSON response and call C++ code" From "Let's use WCF because it supports all possible communication standards" to "REST is simple text-based format, let's stick with it and use simple HTTP handlers"

  • Transition from 2D to 3D Game development [closed]

    - by jakebird451
    I have been working in the 2D world for a long time from manual blitting in windows to SDL to Python (pygame, pyopengl) and a bunch in between. Needless to say I have been programming for a while. So a while ago I started to program in OpenGL via C++ on my Mac. I then got a little intricate with my work after a while (3D models with skeleton structure and terrain development). After a long time of tinkering, I stopped due to the heavy work just to yield a low level understanding of how OpenGL works. Still interested in Graphics and Game Development I went on a search for a stable game engine with some features to grow on. Licence Requirement: Anything other than GPL (LGPL will do) OS Requirement: Mac & Windows Shader: GLSL or CG (GLSL preferred due to experience) Models: Any model structure with rigging (bone) support & animation I am looking at http://www.ogre3d.org/ currently and am starting to meddle around with some examples. However I am a little reluctant to spend a lot of time on it only to yield another dead end. So instead of falling down a spiraling black pit, I am posting my question to you guys to lead me in the right direction based on my requirements. How was your experience with the engine you recommend? Is it well documented? Does it have well documented examples? Any library requirements (Boost, libpng, etc)?

  • How do I apply a computer science degree to web development?

    - by T. Webster
    I'm a web programmer, but I haven't found many opportunities to take advantage of a formal education in computer science. Maybe I'm not looking in the right places, but it seems to me like most of the web jobs I come across are CRUD, web forms, and data grids. For these jobs a formal CS background doesn't seem necessary, and you could do fine with O'Reilly cookbooks in jQuery, CSS 3, PHP, SQL, or ASP.NET MVC. What kinds of web developer jobs exist that really let you apply your computer science background? Do I need to branch out into other areas of programming to take full advantage of my degree?

  • Calling Web Service with Complex Parameters in ADF Mobile

    - by Shay Shmeltzer
    Many of the SOAP based web services out there have parameters of specific object types - so not just simple String/int inputs. The ADF Web service data control makes it quite simple to interact with them. And this applies also in the case of ADF Mobile. Since there were several thread on OTN asking about this - I thought I'll do a quick demo to refresh people memory about how you pass these "complex" parameters to your Web service methods. By the way - this video is also relevant if you are not doing mobile development, you'll basically use the exact same process for building "regular web" ADF applications that access these types of Web services. One more thing you might want to do after you create the page is look at the binding tab to see the method call in there, and notice the parameters for it in the structure property. Go and look at their NDValue property to get the complete picture.
