• From actionscript to google's datastore through java.

  - by Jonathan

  I'm working on a flash game written in pure actionscript 3.0 in Flex. I've just finished implementing replays for the game, but want to store the top 10 hiscores' replay data on my google-app-engine'd website. I'm using Java for the app-engine stuff in Eclipse in java but I have no idea how to deal with communicating to my java code from my actionscript code. I'll need to both read and write from actionscript - java - datastore. Does anyone have any experience with this? For note, I'm horribly noob with anything to do with web development. I hear you can pass arguments to a URL when calling it, comparable to command-line arguments on a desktop executable and if so then sending all the data as a large string would be doable... The question then would be how to call a url from AS3 code with additional data and then how to catch that on the java side. Thanks to anyone who can help. Jono

• how can i make a link in XML

  - by Chi

  I have this flash website that comes with XML. The website is predefined in such a way that when I hoover the mouse cursor over some pictures or text, it will show the pointing hand, thus meaning it's a clickable link. Originally, it would look like so: After I changed the link part, it becomes: However, this seems not to be working (google link is just an example). The pointing hand is still showing, but when I click on it, nothing happens. So my question is quite simple, how do I link in XML (sorry if all this sounded rather stupid, I'm a noob)

• How do you install Castle Windsor IOC?

  - by user300266

  I'm currently reading Pro ASP.NET MVC Framework by Sanderson. In the book he recommends setting up IoC using Castle Windsor, and he points out that the download automatically installs it and registers the Castle DLLs in the GAC. Well, at this point in time (5/4/2010), the Castle Project no longer has a downloadable installer that sets this up. Its all broken out into their individual subprojects with the raw files contained in zipped folders. Sadly there's no installation documentation that I can find about how to set it up. Being the noob that I am, I'm stuck and now forced to ask #1 where should castle windsor live on my hard drive? #2 how do I manually register the dlls properly? And, #3 should I be angry at the project maintainers for their oversight? Here's the link: http://www.castleproject.org/castle/download.html

• Programmaticaly finding the Landau notation (Big O or Theta notation) of an algorithm?

  - by Julien L

  I'm used to search for the Landau (Big O, Theta...) notation of my algorithms by hand to make sure they are as optimized as they can be, but when the functions are getting really big and complex, it's taking way too much time to do it by hand. it's also prone to human errors. I spent some time on Codility (coding/algo exercises), and noticed they will give you the Landau notation for your submitted solution (both in Time and Memory usage). I was wondering how they do that... How would you do it? Is there another way besides Lexical Analysis or parsing of the code? PS: This question concerns mainly PHP and or JavaScript, but I'm opened to any language and theory.

• TDD - A question about the approach

  - by k25

  I have a question about TDD. I have always seen the recommendation that we should first write unit tests and then start writing code. But I feel that going the other way is much more comfortable (for me) - write code and then the unit tests, because I feel we have much more clarity after we have written the actual code. If I write the code and then the tests, I may have to change my code a little bit to make it testable, even if I concentrate much on creating a testable design. On the other hand, if I write the tests and then the code, the tests will change pretty frequently as and when the code shapes up. My questions are: 1) As I see a lot of recommendations to start writing tests and then move on to coding, what are the disadvantages if I do it the other way - write code and then the unit tests? 2) Could you please point me to some links that discuss about this or recommend some books (TDD)?

• Project Management, Developer being project managers manager

  - by marabutt

  I am in the planning stages of a project and am looking to hire a project manager. I want be doing some coding and keeping an eye on all parts of the project but feel a project manager will get better results than I could. I can project manage the project and not code and hire another coder or code myself and hire a project manager. I am worried that the project manager will fell impeded by having the project owner as part of the development team. If I run the project, the team might fall apart causing the project to fail. To stick within budget, I have to be involved in one capacity or another. Does anyone have experience with this situation or suggestions?

• Best practices for team workflow with RoR/Github for designer + coder?

  - by Josh

  My friend and I have started to try to collaborate on some projects. For background, I come from a PHP/Wordpress/Drupal coding background, but recently I've become more experienced with the RoR framework, while he is more experienced as an HTML/CSS designer, working with PHP and WordPress. We're both relatively new to RoR I think, and so we're trying to figure out our collaborative workflow, but we have no idea where to start. For instance, we were trying to figure out how he could do some minor edits to the CSS file without having to do a full RoR deploy on his box. We still haven't figured out a solution, so I think it's best if we start to set some sort of workflow based on best practices. I was wondering if you guys have any insight or links to articles/case studies regarding this topic?

• Java PlayFramework & Python Django GAE

  - by Maik Klein

  I already know Java, C# and C++. Now I want to start with web development and I saw that some really big sites are built with Python/C++. I like the coding style of Python, it looks really clean, but some other things like no errors before runtime is really strange. However, I don't know what I should learn now. I started with Python but then I saw that Google App Engine also supports Java and the PlayFramework looks amazing too. Now I am really confused. Should I go with Python or Java? I found the IDE for Python "PyCharm" really amazing for web development. Does Java have something similar, eclipse maybe? I know that this question isn't constructive, but it will help me with my decision. What are pro and cons of both languages?

• What Agile Model do you use at Work?

  - by Kyle Rozendo

  I am looking to start pushing for more Agile processes to be brought into play in the work place and do my best to outlaw cowboy coding as much as possible. I understand many of the different models and am just looking to see which model has the higher uptake (or which parts of the model as well), and in what industry it is being used. Extreme Programming (XP) Adaptive Software Development (ASD) Scrum Dynamic Systems Development Model (DSDM) Crystal Feature Driven Development (FDD) Lean Software Development (LSD) Agile Modelling (AM) Agile Unified Process (AUP) Kanban If you care to add to your answer with comments about what you don't like, do like or have tried and it hadn't worked, that would also be appreciated.

• libgdx spite position relative to body

  - by While-E

  Apologies if this is a reiteration, as I couldn't find another discussion of this over the past couple days. Issue: I'm using libgdx and box2d, and I'm currently updating the sprite's position to the body's current position every render call. Using a debugRenderer to see the bodies, I see that there is fairly noticeable lag between the movement/position of the body and the sprite that is being moved relative to it. Question: Is this lag normal, possibly to perform collisions ahead of time? If not, should I be manipulating/relating the positions differently? Thanks in advance! [Solution] This was a coding error on my part. Pointed out by a good reply below, I was updating the position of the sprite relative to the body and then stepping the physics. Thus never actually setting the sprite to the body's CURRENT position. Thanks!

• Trying to find a good strategy using Git for personal development on local/personal machine

  - by AJ

  A noob here. I have a personal Macbook and I want to use Git to track the changes etc. I want to just init a repo on my macbook and work there. Is this a good idea? What if: I have a main repo somewhere in my Macbook HD, like, /Users/user/projects/project1 and clone it to another area on my macbook where I actually perform development? But there is a lot of redundancy in this. I am a little confused and want to know what are the usual steps folks take in a similar personal development environment. Thanks a lot.

• What are reasons for Unity3D's owners to force rich guys buying Pro version?

  - by mhambra

  Well, I have to say that Unity is a really nice thing that can save one a dozen of hours on coding (letting instantly work on gameplay). But what's the idea of forcing (EULA) any party, which made over 100k last fiscal year, to purchase Pro instead of using normal edition!? It feels that this kind of licensing provides hidden benefits to rich guys over me, poor sloven, who can afford buying $3.5k license but obviously will not receive any additional cookies from it. And, by the way, anyone estimated how much Unity's source + Playstation + Xbox license will cost?

• Specify Action on sub-controller when using Html.RenderAction

  - by iammaz

  I have a UserControl that I call with Html.RenderAction(...), so far so good.. Then I want to specify in the user control, which action should be used Html.BeginForm("DeleteComment", "Comments", new { Id = "frmDelete" }, FormMethod.Post);%> <%= Html.SubmitImage( "imgbtnDelete", "/image.png", new { ... })%> <% Html.EndForm(); %> And therein lies my problem; this calls the user control's controller/action. What I want to happen is to call the pages action first and then be able to specify what action to call on the user control's controller. Is this possible?? Thanks from an MVC noob

• The joomla 'create a template' tutorial

  - by ryan

  Hello all, Ive recently downloaded joomla using an instant download option, and now im looking to create my own templates, so i went to http://www.siteground.com/tutorials/joomla15/joomla_create_template.htm and Im trying to follow the tuturial but ive failed at the first hurdle... where it says "First, open the "templates" directory in your Joomla installation. Then create a subfolder in it named "tutorial_template". All the files of your template will reside in it." The problem is I have no clue how to do this, where is the directory to start with?? the only thing I know how to get up is the administrators screen, in which I have to choose one of the stock templates, which would be great if I didnt care about my own designs...but obviously im looking to have my own html and css coding used instead. How do I find where the folders are and how do I open them? Im sorry if its a bit of a dumb question but im so confused..so early on. Thanks in advance. Ryan

• Introduction tutorial/s for web accessibility?

  - by Arnis L.

  I've ignored this topic for really long time and I would like to get at least basic instincts on this subject (You know - more than "don't forget to add alt on images"). Assuming that I'm complete noob on this, where should i look first? Please, do not just post some ISO standards, html spec or whatnot. That will just recoil any interest. I'm looking for gentle push with guidelines where to look next. P.s. I did try to find duplicate question/s w/o any luck.

• Convert an Enum to String

  - by Aamir Hasan

   Retrieves the name of the constant in the specified enumeration that has the specified value. If you have used an enum before you will know that it can represent numbers (usually int but also byte, sbyte, short, ushort, int, uint, long, and ulong) but not strings. I created my enum and I was in the process of coding up a lookup table to convert my enum parameter back into a string when I found this handy method called Enum.GetName(). using System;public class GetNameTest { enum Colors { Red, Green, Blue, Yellow }; enum Styles { Plaid, Striped, Tartan, Corduroy }; public static void Main() {Response.Write("The 4th value of the Colors Enum is" + Enum.GetName(typeof(Colors), 3));Response.Write("The 4th value of the Styles Enum is "+ Enum.GetName(typeof(Styles), 3)); }}Reference:http://msdn.microsoft.com/en-us/library/system.enum.getname.aspxhttp://www.studentacad.com/post/2010/03/31/Convert-an-Enum-to-String.aspx
