  • How to handle javascript & css files across a site?

    - by Industrial
    Hi everybody, I have had some thoughts recently on how to handle shared javascript and css files across a web application. In a current web application that I am working on, I got quite a large number of different javascripts and css files that are placed in an folder on the server. Some of the files are reused, while others are not. In a production site, it's quite stupid to have a high number of HTTP requests and many kilobytes of unnecessary javascript and redundant css being loaded. The solution to that is of course to create one big bundled file per page that only contains the necessary information, which then is minimized and sent compressed (GZIP) to the client. There's no worries to create a bundle of javascript files and minimize them manually if you were going to do it once, but since the app is continuously maintained and things do change and develop, it quite soon becomes a headache to do this manually while pushing out new updates that features changes to javascripts and/or css files to production. What's a good approach to handle this? How do you handle this in your application?

  • what do you expect from flash in the near future?

    - by algro
    The recent article of steve jobs link made me think about the future of flash. I'm learning actionscript 3.0 in my studies but is it the right decision still to go for it? I was pretty sure that I will be able to build application in as3 for iphones/ipads in the near future. It seems to me, while I would stay with flash, the market will be polarized by apple and adobe and you will always work double for both clientele, or just lose half of them. Which decision would you take as a designer, if you were still at university and you intend to become a freelancer?

  • Which web solution should I use for my project?

    - by BenIOs
    I'm going to create a fairly large (from my point of view anyway) web project with a friend. We will create a site with roads and other road related info. Our calculations is that we will have around 100k items in our database. Each item will contain some information like location, name etc. (about 30 thing each). We are counting on having a few hundred thousand unique visitors per month. The 100k items and their locations (that will be searchable) will be the main part of the page but we will also have some articles, comments, news and later on some more social functions (accounts, forums, picture uploads etc.). We were going to use Google AppEngine to develop our project since it is really scalable and free (at least for a while). But I'm actually starting to doubt that AppEngine is right for us. It seems to be for webbapps and not sites like ours. Which system (language/framework etc.) would you guys recommend us to use? It doesn't really mater if we know the language since before (we like learning new stuff) but it would be good if it's something that is future proof.

  • Tool to maintain a Data Mapping between two systems

    - by ktaylorjohn
    We have XML interfaces between multiple systems. An Enterprise Domain Model is missing in the overall architecture, hence the terms Product/Customer/User means different things to different systems. We currently use excel sheets to map the elements in incoming XML to what the actual Field means within our system. Additionally, it contains the values of Mandatory/Optional and length of each field. We call this the Data Dictionary. Any changes to the XML go through rounds of deliberation and updates to Word and Excel documents. Is there a better way to do this? Any tool/GUI based approach which all systems and owners can view?

  • Overview of mobile browsers and their features?

    - by Janusz
    I'm looking for a comparison of the features of mobile browsers. Most interesting are the default preinstalled browsers. I would love a matrix that shows what device line can do what with their preinstalled browser. There is a list with rendering engines on wikipedia but there should be differences appart from the rendering right?

  • Which version of .NET is available for Xbox 360?

    - by Rosarch
    I tried to look this up on MSDN, but couldn't get a straight answer. It says: The .NET Compact Framework for Xbox 360 implements a subset of the .NET Compact Framework, and has been optimized to take advantage of and expose the power of the Xbox 360. What exactly is the subset? Which version of the framework? 3.5? 2.0?

  • In Magento, how can I preview a page before saving it?

    - by jeremysawesome
    I am using the Magento ver. 1.4.0.1 Community Edition. The problem I am running into is that Magento only allows me to preview pages that I have already saved. This works fine if I am creating a new page - but what if I am editing a current page? I want to be sure that the changes I make look good on the site before saving them. Does anyone know of a way to preview a static cms page before saving the changes made? I'm open to using some sort of plugin if anyone knows of one. Thanks

  • What is the standard way of using a sitemap with pages that require specific information passed to t

    - by Mike
    Hi, I have a website for which many pages rely on information passed to them (usually in the form of a querystring) or on a session variable. When making a web application, how do you normally handle these particular pages in regards to the sitemap? If you're using the standard ASP.NET menu control, it will render the node on the menu and if you click it, you could get an exception stating that a session variable doesn't exist (if it hasn't been created yet). For example, if you're making a user management area: All of these nodes get rendered, but I don't want the user to click on edit user or delete user without specifying someone to edit or delete. Any tips or suggestions would be greatly appreciated.

  • Very Urgent :How to start a new session if a user click on the new tab in IE or mozilla on websphere

    - by ha22109
    Hi, I have one "user search" portlet on the home page of one application running on websphere portal server.Which display the matching user records as per the search criteria filled in the search form.I have requirement to have a "back to search input" link on the results page which onclick should show the filled form on the input jsp. The issue which i am facing is if i open the application in two diff tab of same IE browser and start giving some search criteria and submit and same time search for some other input from other IE tab (in the same browser)and then go back to previous tab and click on "back to search input" link then instead of showing me the first input it will show me the imput which i entered in the next IE tab. I am setting and getting the bean(form bean) through portlet session.but in the two diff tab of same IE it will be the sae user session (and may be the same portlet session..) Please tell me solution for this. The one thing to be notice here is i can access this "user search" application even without doing login also.so it must be taking the default portlet session in this case. what wil happen once i login and then search,will it going to overwrite the portlet session and http session or howz is that?

  • Uniquely identifying mobile devices over a network for webforms

    - by Eric
    I'm designing a system for mobile devices that can be assigned only to one job at a time. So I need to be able to know which mobile device is being used by accessing it's own unique static IP address or its device ID. I don't want to assign an ID myself for every machine that comes in which is why a static IP would work great. However, in trying to retrieve the client ip address I'm retrieving the wireless router's ip or some other ip which is not the mobile device's ip. I want to store that ip in a table and control which jobs are assigned to it. How can I accomplish this? I've tried the following but I'm getting the wireless ip: var hostEntry = Dns.GetHostEntry(Dns.GetHostName()); var ip = ( from addr in hostEntry.AddressList where addr.AddressFamily.ToString() == "InterNetwork" select addr.ToString() ).FirstOrDefault(); I'd rather not set a cookie if there exists a better alternative. TIA!

  • C++: Platform indepentend game lib?

    - by Martijn Courteaux
    Hi, I want to write a serious 2D game, and it would be nice if I have a version for Linux and one for Windows (and eventually OSX). Java is fantastic because of its platform independent. But Java is to slow to write a serious game. So, I thought to write it in C++. But C++ isn't very cross-platform friendly. I can find game libraries for Windows and libraries for Linux, but I'm searching one that I can use for both, by recompiling the source on a Windows platform and on a Linux platform. Are there engines for this or is this idea irrelevant? Isn't it that easy (recompiling)? Any advice and information about C++ libraries would be very very very appreciated!

  • Sys. engineer has decided to dynamically transform all XSLs into DLLs on website build process. DLL

    - by John Sullivan
    Hello, OS: Win XP. Here is my situation. I have a browser based application. It is "wrapped" in a Visual Basic application. Our "Systems Engineer Senior" has decided to spawn DLL files from all of our XSL pages (many of which have duplicate names) upon building a new instance of the website and have the active server pages (ASPX) use the DLL instead. This has created a "known issue" in which ~200 DLL naming conflicts occur and, thus, half of our application is broken. I think a solution to this problem is that, thankfully, we're generating the names of the DLLs and linking them up with our application dynamically. Therefore we can do something kludgy like generate a hash and append it to the end of the DLL file name when we build our website, then always reference the DLL that had some kind of random string / hash appended to its name. Aside from outright renaming the DLLs, is there another way to have multiple DLLs with the same name register for one application? I think the answer is "No, only between different applications using a special technique." Please confirm. Another question I have on my mind is whether this whole idea is a good practice -- converting our XSL pages (which we use in mass -- every time a response from our web app occurs) into DLL functions that call a "function" to do what the XSL page did via an active server page (ASPX), when we were before just sending an XML response to an XSL page via aspx.

  • Loading jQuery multiple times in the same page

    - by Winaji
    I'm implementing a plug-in that's embeddable in different sites (a la Meebo, Wibiya), and I want to use jQuery. Problem is, the site I'm embedding to, may already have a jQuery script loaded. The question is, what's the best approach for this kind of problem: Should I just check if jQuery is already loaded and if so, use the original site's jQuery, otherwise load it myself? If I use this approach, am I not risking comaptibility problems (i.e. the site uses an old version of jQuery)? Should I load jQuery myself (whether it's already loaded or not) and call "jQuery.noConflict(true)" when it's finished loading? If so, how can I make sure that my jQuery has finished loading (hooking to the onLoad event doesn't seem to work all the time, and polling for "jQuery" won't work for obvious reasons)? Should I do something else? Thanks.

  • Cocos2d score resetting is messing up (long post warning)

    - by Jhon Doe
    The score is not resetting right at all,I am trying to make a high score counter where every time you passed previous high score it will update.However, right now it is resetting during the game. For example if I had high score of 2 during the game it will take 3 points just to put it up to 3 as high score instead of keep going up until it is game over. I have came to the conclusion that I need to reset it in gameoverlayer so it won't reset during game. I have been trying to to do this but no luck. hello world ./h #import "cocos2d.h" // HelloWorldLayer @interface HelloWorldLayer : CCLayer { int _score; int _oldScore; CCLabelTTF *_scoreLabel; } @property (nonatomic, assign) CCLabelTTF *scoreLabel;

  • why does django-registration use an "activation window" for activating accounts?

    - by bharal
    i'm using django-registration, which is a django lib that helps with users registering on a django-built website. All well and dandy, except that it insists i have an "activation email" associated with all new users. It defaults to a 7 day window, after which, if someone signed up (and we then sent an email to confirm their email address) but didn't click on the link in the sent email within the 7 days, then they cannot sign up. Instead, they need to do the whole process all over again. I'm sure this is a concept that exists generally in web design, because why would django-registration make its own arbitrary signup process up? Anyway, the question is why? What do i gain by having the peace of mind knowing that all the users of my site are the kind of go-getters that click on registration emails with 7 days of receiving them? Why should i sleep easier knowing that my database isn't filled with users who, for whatever reason, clicked through to sign up but didn't actually want to sign up? cheers!

  • What's wrong with the architecture of a game object drawing and updating itself?

    - by Ricket
    What are the reasons for and against a game object drawing and updating itself? For example, if you have a game where the player has a position on screen, why not have an all-encompassing class: public class Player { private int x, y, xVelocity, yVelocity; private Sprite s; //... public Player() { // load the sprite here, somehow? } public void draw(CustomGraphicsClass g) { g.draw(s, x, y); } public void update(long timeElapsed) { x += (xVelocity * timeElapsed); y += (yVelocity * timeElapsed); } } What is wrong with this design? What are the downfalls or concerns? How would you better write something like this, or better architect this type of thing in a game? Also, somewhat connected, how would you implement loading that Sprite image? And furthermore, how would you then implement collision between two Players? (I should probably separate these extra two questions into new questions, huh?)
