  • Best way to redirect users back to the pretty URL who land on the _escaped_fragment_ one?

    - by Ryan
    I am working on an AJAX site and have successfully implemented Google's AJAX recommendation by creating _escape_fragment_ versions of each page for it to index. Thus each page has 2 URLs: pretty: example.com#!blog ugly: example.com?_escaped_fragment_=blog However, I have noticed in my analytics that some users are arriving on the site via the "ugly" URL and am looking for a clean way to redirect them to the pretty URL without impacting Google's ability to index the site. I have considered using a 301 redirect in the head but fear that Googlebot might try to follow it and end up in an endless loop. I have also considered using a JavaScript redirect that Googlebot wouldn't execute but fear that Google may interpret this as cloaking and penalize the website. Is there a good, clean, acceptable way to redirect real users away from the ugly URL if for some reason or another they end up arriving at the site that way?

  • How relevant is PHP today for browser games?

    - by Bitgarden
    I was the lead developer of 2 moderately successful browser games quite a few years back, and plan on working on a new game soon. At the time, I wrote them in pure PHP (no template engine or anything of the sort). I'd like to start working on a new game, but have been out of the web development world for a while. Reading around, I hear a lot of good about Rails, Django, Node.js, etc., with which I have no experience (although I know my way around Python, Javascript, and the others quite well). So my question is the following- if I were to go in my old ways and go with PHP again, would I be making things hard for myself? Would picking something more "trendy" have a real impact on my development? In addition, does anyone have any pointers relating to specifically developing browser games with these more modern tools?

  • What web oriented language would work best with binary data?

    - by Qqwy
    I want to create a service where people can upload files. However, since file storage costs money, I want to compress the files so they take less space. I would want to write my own compression algorithm, however, PHP doesn't have good ways to handle binary data (which is needed for many compression algorithms). So I wondered, what would be a better language to create such a website in? I have knowledge of PHP (and Javascript, HTML and CSS) but no experience with other things like Ruby, Perl, Python, and other web development languages.

  • Waiting for Windows 8: A Long, Hot Summer

    - by andrewbrust
    Microsoft has revealed some things about Windows 8, and revealed a part of the developer story for new Windows 8 “tailored,” “immersive” applications.  In retrospect, very little was shared.  The bit that was revealed to us is that those applications can be developed using a combination of HTML 5 and JavaScript.  Not much else was said, except that additional details would be revealed at Microsoft’s //Build/ conference in Anaheim, California in September. This has left a lot of people in suspense, and it seems that suspended state is going to last all summer.  The problem, of course, is that in the absence of hard information, people fill the void with Speculation, Rumor and Gloom.  That’s a bit like Fear, Uncertainty and Doubt, except that it’s self-imposed by the Microsoft community and not planted by Microsoft’s competitors. This is a less-than-perfect situation.  Not only is it causing developers to worry about the value of their skill sets, but I am already hearing from consulting shops that customers are getting nervous too and, in extreme cases, opting for non-Microsoft tools for their projects as a result.  I’m also hearing from dev tool ISVs that sales have suffered as a result. It’s quite possible that the customers moving off .NET wanted to do so anyway and it’s also possible that dev tool ISVs are suffering slower sales this year due a slowed rate of economic recovery. Without hard information, tend to people interpret things negatively.  Actually, that’s the major point in all of this. While there is multitude of opinions about what the Windows 8 development platform will look like once fully revealed, there is an emerging consensus around one thing: it sure would help if Microsoft revealed more of its strategy…just enough to quash absurd rumors, stabilize the .NET ecosystem and get people to stay calm. We’ve had some reassurances thus far: there will be a Windows desktop mode; we’ll still have Windows Explorer, we’ll still run Office, we’ll still have a task bar, and all the skills and tools we use now will still work there.  But with reassurances like that…people still feel insecure.  Because telling us that Windows 8 will have what is essentially a “classic” mode sure makes it sound like today’s skill sets will soon be “classic” too…and then maybe they’ll just become obsolete. Humans find change scary; it’s natural.  And when left alone with their fears – because no one is saying anything to dispel them – people can go from frightened to paranoid, and can start to viewing things in a downright conspiratorial light.  It would be great if Microsoft stepped into the void now and told us what is coming – especially because whatever they tell us is bound to be at least a little better than what people think they are going to hear. I don’t know what the announcements will be, but I do have it on authority, from a number of sources, that Microsoft isn’t gong to talk until //Build/.  That means no news until September September 13th.  Nothing until after Labor Day.  You get zippo until after the Back-to-School sales are done. What to do?  Try not to let the dark voices of gloom and doom fill your head.  Even in the absence of answers, we still have some important facts: The .NET developer community is huge. Microsoft’s customers have major investments in .NET, and in .NET skills. Political infighting in Redmond might make for irrational decisions, but ultimately public companies can’t just alienate their advocates and piss off their customers.  Spite doesn’t trump fiduciary responsibility. The computing device markets are changing, software is changing, software business models are changing and developers are changing.  Microsoft has to keep up. The HTML + JavaScript community is huge too, and it includes many of the “changed” developers. Public companies can’t ignore new markets nor the popular standards that can help them enter those new markets.  Loyalty doesn’t trump fiduciary responsibility either. If Microsoft can appeal to new developers, then it should. If Microsoft can keep catering to its existing developers and customers -- not just through legacy support, but also through empowering futures -- then it probably will. You don’t have to shove your old friends out into the rain to make room for new ones; you can bring those new constituents in under a bigger tent.  I hope Microsoft will enlarge the tent, and I have trouble imagining why it would not.

  • Futures/Monads vs Events

    - by c69
    So, the question is quite simple: in an application framework, when performance impact can be ignored (10-20 events per second at max), what is more maintainable and flexible to use as a preferred medium for communication between modules - Events or Futures/Promices/Monads ? Its often being said, that Events (pub/sub, mediator) allow loose-coupling and thus - more maintainable app... My experience deny this: once you have more that 20+ events - debugging becomes hard, and so is refactoring - because it is very hard to see: who, when and why uses what. Promices (i'm coding in javascript) are much uglier and dumber, than Events. But: you can clearly see connections between function calls, so application logic becomes more straight-forward. What i'm afraid. though, is that Promices will bring more hard-coupling with them... p.s: the answer does not have to be based on JS, experience from other functional languages is much welcome.

  • Browser support for internal corporate tools

    - by adam
    We are on the verge of a conversion. For years, our company supported only IE for its internal (intranet) home-built tools. Since a few of our users are still on XP, which means IE only goes up to 8... a heavily JS / jQuery site wont even load! We have been in the process of converting to use Chrome instead, to make use of its javascript performance. But, it has now been suggested that we support all common browsers... internally for these tools. Which means more development time to scale-back some of these new applications, more time to test in all browsers, and we are already under staffed. Are there any good informational sites/posts out there, that already make this argument?

  • What undergraduate course to choose for a mature programmer returning to study

    - by Dve
    I have been developing applications (mostly web-based) for almost 10 years now and have learnt pretty much everything I know through experience (and the internet!). I wouldn't call myself an advanced programmer, but I am quite proficient in several languages (C#, Javascript, Ruby, HTML/CSS etc) and spend a quite a bit of time working on personal projects and reading countless books & articles. I am looking to emigrate to Canada, hopefully Vancouver (im from the UK) and one way would be on a student visa, if I was going to be studying for a minimum of 2 years. Having never been to university or achieved anything higher than A-Levels I am quite tempted by this path. The thought of learning is more exciting to me now than it was 10 years ago! What would be people recommend as a good undergraduate course to take that would complement this career path? Would Math be beneficial, if so which area of Math? TL;DR What undergraduate course/area of study would complement 10 years of (mostly web-based) programming experience?

  • Common reasons for the &lsquo;Sys is undefined&rsquo; error in ASP.NET Ajax applications

      In this blog I will try to summarize the most common reasons for getting the famous 'Sys is undefined' error when running an Ajax enabled web site or application (there are almost one milion results on Google for that phrase). Where does it come from? In every Ajax web pages source you will see a code like this: <script type="text/javascript"> //<![CDATA[ Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('form1')); Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90); //]]> </script>   This is the initialization script of the ScriptManager. So, if for some reason the Sys namespace is not available when the code executes you get the Sys is undefined error. Here are the most common reasons and solutions for that problem:   1. The error occurs when you have added a control from RadControls for ASP.NET AJAX, but your application is not configured to use ASP.NET AJAX. For example, in VS 2005 you created a new Blank Site instead of a new Ajax-Enabled Web Site and the Sys is undefined message pops up. To fix it you need to follow the steps described at Configuring ASP.NET Ajax article (check the topic called Adding ASP.NET AJAX Configuration Elements to an Existing Web Site) or simply create the Ajax-Enabled Web Site. You can also check my other blog post on the matter: Visual Studio 2008: Where is the new ASP.NET Ajax-Enabled Web Site template?   2. Authentication - as the website denies access to all pages to unauthorized users, access to the Telerik.Web.UI.WebResource.axd handler is unauthorized (this is the default handler of RadScriptManager). This causes the handler to serve the content of the login page instead of the combined scripts, hence the error. To solve it - add a <location> section to the application configuration file to allow access to Telerik.Web.UI.WebResource.axd to all users, like: <configuration> ... <location path="Telerik.Web.UI.WebResource.axd"> <system.web> <authorization> <allow users="*"/> </authorization> </system.web> </location> ... </configuration>   Note that the access to the standard ScriptResource.axd and WebResource.axd is automatically allowed for all users (authenticated and unauthenticated), so if you use the ScriptManager instead of RadScriptManager - you will not face this problem. The authentication problem does not manifest when you disable script combining or use the CDN. Adding the above configuration section will make it work with RadScriptManagers combined script.   3. The IE6 browser fails to load the compressed script. The problem does not appear in any other browser. There is a well known bug in the older versions of IE6 which lose the first 2,048 bytes of data that are sent back from a Web server that uses HTTP compression. Latest versions of RadScriptManager does not compress the output at all if the client is IE6, but in the previous versions you need to manually disable the output compression to prevent the error. So, if you get the Sys is undefined error in IE6 - update to the latest version of RadControls or simply disable the output compression.   4. Requests to the *.axd files returns Error Code 404 - Not Found. This could  be fixed easily: Check in the IIS management console that the .axd extension (the default HTTP handler extension) is allowed:     Also check if the Verify if file exists checkbox is unchecked (click on the Edit button appearing in the previous screenshot to check). More information can be found in our troubleshooting article and from the ASP.NET QA team blog post   5. The virtual directory in IIS is not marked as Web Application. Converting it to Web Application should fix the problem.   6. Check for the <xhtmlConformance mode="Legacy"/> option in your web.config and remove it. It would be rather rare to become a victim of this exact case, but still have it in mind. Scott Guthrie describes it in more details   In the above points I mentioned several times the terms web resources, javascript output, compressed script. If you want to find out more about these please see the Web Resources Demystified series of my friend and colleague Atanas Korchev   I hope that one of the above solutions will help you get rid of the Sys is undefined error.   Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • best programming language for a web based game?

    - by Adam Geisweit
    what programming language would be best for making a web based game to be played in a browser, and where would i be able to find tutorials on how to use the language? i have looked up silverlight in xna (because that was what i was most fluent with), but it made my projects unusable for a month until i got all of silverlight off my computer. i have looked at java and javascript, but i have found no suitable places where i can learn to create games on either of these, just the basics of the language. does anyone have any advice on this?

  • Hidden text and links appearing just on click for SEO?

    - by CamSpy
    I am working on a site that has neat clean/minimalistic design/layout. Menu items are "hidden" behind an icon, to see them, users need to click on that icon to get a javascript toggled overlay with the list of menu items. Then there are blocks with photos and users need to click on a small icon/button on each of them to get a block of text shown for each of the photo. While I don't like such "design" myself, making me click lots of time just to read, I also think that for SEO purpose this model is really wrong. Is such model bad for SEO? Are there ways to keep design like this but have "safe" methods of displaying text content on click that will not hurt SEO?

  • Houston We have a Problem with Silverlight Client OM&hellip;

    - by MOSSLover
    So I was playing around with NavigationNodeCollection, which is basically like SPNavigationNodeCollection just to make sure it worked without a hitch…Here is a little sample snippet of what should work: Unfortunately, you get a nice little javascript error that does not allow you to access the child nodes.  I tried a foreach() loop that gets a NavigationNode for each parent then loops through the NavigationNode.Children that did not work either.  I threw in two ExecuteQueryAsync statements thinking that would help, unfortunately adding a second statement provides no different results.  This appears to be a bug in the Silverlight Client Object Model.  I reported the error.  Hopefully, we get a fix by RTM so that we can use the easier method to get items into Silverlight, otherwise it’s back to WCF and cross domain policies.  We all love cross domain policies right?

  • How can I neatly embed Flash in a page in a way that is cross-browser compatible?

    - by Mark Hatton
    When I receive Flash objects from my designer, it comes with an example HTML page which includes both <object> tags and <embed> tags as well as a whole heap of JavaScript. If I copy and paste this code in to my webpage, it works, but the code looks a mess (and there is so much of it!). If I remove the extra code and try either just <embed> or <object> on their own, it works in some browsers, but not others. Is there a neat, minimal method that works in all the major browsers?

  • Can I make Google Analytics set its cookies on just a subdomain? (I.e. www.domain.com, not domain.com)

    - by Paul D. Waite
    I’m using Google Analytics on a site — let’s call it www.domain.com. My Google Analytics website profile is for www.domain.com, and my only report is set up for www.domain.com. Requests to domain.com redirect permanently to www.domain.com. I’ve got the regular Analytics JavaScript on my index page for the domain. For some reason, it seems to be setting its cookies for domain.com instead of www.domain.com. This is unfortunate, as I’ve got cdn.domain.com set up as a CDN using Amazon Cloudfront, so I’d rather not have useless cookies (Analytics seems to set four cookies) cluttering up those requests. How can I make Analytics set cookies for www.domain.com instead of domain.com?

  • Looking for a 24 Hour project for multiple languages [closed]

    - by Daan Timmer
    Right two friends and I came up with this idea of having a 24h programming competition. Where we are going to meet at one place and program away for 24hours long. Though we need a 'project'. Something that needs to be made within 24h. Doesn't have to be a real thing, just a nice learning 'thing'. The rules that we setup for ourselves is that the project can be programmed in any language of our own choice. What I know is that one guy is a PHP enthousiastic, we've got a C#/.NET person. And I am quite easy in languages and speak quite a few (PHP/C#.net/C++STL/Python/JavaScript/Java). Anything really language specific is out of the question. Is there anyone who happens to have a great idea for this?

  • Recommendations for a quick and easy discussion forum installation

    - by BeachRunnerJoe
    Hello. I did a couple quick searches on this topic and both Google and this site yielded poor results, but I was wondering what's the quickest way to setup a discussion forum on my website. Preferably one that has a decent Admin dashboard. My website is very static (e.g. it has one index.html, a stylesheet, and a javascript) and it will most likely be hosted on GoDaddy.com. The last time I installed a discussion forum was six years ago and it was phpBB. I'm sure that's still an option, but I'm (hoping) wondering if there are better, free, and as-easy alternatives to phpBB. Thanks for your wisdom!

  • What server-side language should I learn to be able to start big user-input websites (like twitter, facebook, stackexchange...)?

    - by DarkLightA
    I'm thinking ASP.NET, but I don't really know. Can someone tell me what a good server-side language for the "Zuckerberg-dorm-room-starting-up-a-huge-website" deal? I know the latter used PHP, but as I've understood it that's kind of outdated and C#/ASP.NET is a better way to go about it. Is HTML + CSS + JavaScript + C#/ASP.NET MVC + MySQL a good combination for it? Is MySQL combined in ASP.NET MVC? Also, where's a good tutorial for the server-side language you suggest? As mentioned previously it has to be able to handle massive user-input without much fuss.

  • Apress Books - 3 - Pro ASP.NET 4 CMS (ISBN 987-1-4302-2712-0) - Final comments

    - by TATWORTH
    This book is more than just  a book about an ASP.NET CMS system -  it has much practical advice and examples for the Dot Net web developer. I liked the use of JQuery to detect that JavaScript was not enabled. One chapter was about MemCached - this one chapter could justify the price of the book if you run a server farm and need to improve performance. Some links to get you started are: Windows Memcache at http://code.jellycan.com/memcached/ Dot Net Access Library at http://sourceforge.net/projects/memcacheddotnet/ The chapters on scripting, performance analysis and search engne optimisation all provide excellent examples. This certainly is a book that should be part of every Dot Net Web Development team library. Congratulations to the author and to Apress for publishing this book!
