• How much does Website Development cost nowadays?

  - by Andreas Grech

  I am thinking of setting up my own freelance business but coming from a workplace that offers a particular service to huge clients, I do not know what are the current charges for websites are nowadays. I know that as technology just keeps changing and changing (most of the time, for the better...), the amount you charge for a single website is constantly differing. Like for example, I don't think static websites (with just static html pages) are that expensive today, no? (as i said, I might be mistaken since I haven't really touched on this freelance industry yet) So, freelance web-developers out there, can you give me estimates on how much you charge for your clients? Some examples of websites that I want to know an approx charge: ~10 static html pages ~10 dhtml pages (with maybe a flasy menu on the top/side) Database driven websites with a standard CMS (be it the one you developed, or an existing one) Database driven but with a custom-built cms for the particular client Using an existing template for a design Starting the design from scratch etc... I know that the normally clients don't really care about the technologies used to construct their websites, but do you charge differently according to which technology you use to build the website with?; as in, is the technology a factor when setting the price? ...being ASP.Net, PHP, Ruby On Rails etc... Also, how do you go on about charging your clients for your services? What are the major factors that you consider when setting a price tag for a website to a client ? And better yet, how do you even find prospective clients? <= [or should I leave this question for a different post?] Btw, in your post, also mention some numbers (in cash values, be it in USD, GBP, EUR or anything) because I want to be able to take calculate some averages from this post when some answers stack up

• UTF8 charset, diacritical elements, conversion problems - and Zend Framework form escaping

  - by imanc

  Hey, I am writing a webapp in ZF and am having serious issues with UTF8. It's using multi lingual content through Zend Form and it seems that ZF heavily escapes all of these characters and basically just won't show a field if there's diacritical elements 'é' and if I use the HTML entity equivalent e.g. é it gets escaped so that the user will see 'é'. Zend Form allows for having non escaped data, but trying to use this is confusing, and it seems it'd need to be used all over the place. So, I have been told that if the page and the text is in UTF8, no conversion to htmlentities is required. Is this true? And if the last question is true, then how do I convert the source text to UTF8? I am comfortable setting up apache so that it sends a default UTF8 charset heading, and also adding the charset meta tag to the html, but doing this I am still getting messed up encoding. I have also tried opening the translation csv file in TextWrangler on OSX as UTF8, but it has done nothing. Thanks! L

• ambient values in mvc2.net routing

  - by Muhammad Adeel Zahid

  Hello Everyone, i have following two routes registered in my global.asax file routes.MapRoute( "strict", "{controller}.mvc/{docid}/{action}/{id}", new { action = "Index", id = "", docid = "" }, new { docid = @"\d+"} ); routes.MapRoute( "default", "{controller}.mvc/{action}/{id}", new { action = "Index", id = "" }, new { docConstraint = new DocumentConstraint() } ); and i have a static "dashboard" link in my tabstrip and some other links that are constructed from values in db here is the code <ul id="globalnav" class = "t-reset t-tabstrip-items"> <li class="bar" id = "dashboard"> <%=Html.ActionLink("dash.board", "Index", pck.Controller, new{docid =string.Empty,id = pck.PkgID }, new { @class = "here" })%> </li> <% foreach (var md in pck.sysModules) { %> <li class="<%=liClass%>"> <%=Html.ActionLink(md.ModuleName, md.ActionName, pck.Controller, new { docid = md.DocumentID}, new { @class = cls })%> </li> <% } %> </ul> Now my launching address is localhost/oa.mvc/index/11 clearly matching the 2nd route. but when i visit any page that has mapped to first route and then come back to dash.board link it shows me localhost/oa.mvc/7/index/11 where 7 is docid and picked from previous Url. now i understand that my action method is after docid and changing it would not clear the docid. my question here is that can i remove docid in this scenario without changing the route. regards adeel

• When to choose which machine learning classifier?

  - by LM

  Suppose I'm working on some classification problem. (Fraud detection and comment spam are two problems I'm working on right now, but I'm curious about any classification task in general.) How do I know which classifier I should use? (Decision tree, SVM, Bayesian, logistic regression, etc.) In which cases is one of them the "natural" first choice, and what are the principles for choosing that one? Examples of the type of answers I'm looking for (from Manning et al.'s "Introduction to Information Retrieval book": http://nlp.stanford.edu/IR-book/html/htmledition/choosing-what-kind-of-classifier-to-use-1.html): a. If your data is labeled, but you only have a limited amount, you should use a classifier with high bias (for example, Naive Bayes). [I'm guessing this is because a higher-bias classifier will have lower variance, which is good because of the small amount of data.] b. If you have a ton of data, then the classifier doesn't really matter so much, so you should probably just choose a classifier with good scalability. What are other guidelines? Even answers like "if you'll have to explain your model to some upper management person, then maybe you should use a decision tree, since the decision rules are fairly transparent" are good. I care less about implementation/library issues, though. Also, for a somewhat separate question, besides standard Bayesian classifiers, are there 'standard state-of-the-art' methods for comment spam detection (as opposed to email spam)? [Not sure if stackoverflow is the best place to ask this question, since it's more machine learning than actual programming -- if not, any suggestions for where else?]

• Problem with my Jquery loading in my Codeigniter views

  - by sico87

  Hello, I am working on a one page website that allows the users to add and remove pages from there navigation as and when they would like too, the way it works is that if the click 'Blog' on the main nav a 'Blog' section should appear on the page, if they then click 'News' the 'News' section should also be visible, however the way I have started to implement this it seems I can only have one section at a time, can my code be adpated to allow multiple sections to shown on the main page. Here is my code for the page that has the main menu and the users selections on it. <!DOCTYPE html> <head> <title>Development Site</title> <link rel="stylesheet" href="/media/css/reset.css" media="screen"/> <link rel="stylesheet" href="/media/css/generic.css" media="screen"/> <script type="text/javascript" src="/media/javascript/jquery-ui/js/jquery.js"></script> <script type="text/javascript" src="/media/javascript/jquery-ui/development-bundle/ui/ui.core.js"></script> <script type="text/javascript" src="/media/javascript/jquery-ui/development-bundle/ui/ui.accordion.js"></script> <script type="text/javascript"> $(document).ready(function() { $('a.menuitem').click(function() { var link = $(this), url = link.attr("href"); $("#content_pane").load(url); return false; // prevent default link-behavior }); }); </script> </head> <body> <li><a class="menuitem" href="inspiration">Inspiration</a></li> <li><a class="menuitem" href="blog">Blog</a></li> <div id="content_pane"> </div> </body> </html>

• In IE8, jquery-ui's dialog set the height of its contents to zero. How can I fix this?

  - by brahn

  I am using jquery UI's dialog widget to render a modal dialog in my web application. I do this by passing the ID of the desired DOM element into the following function: var setupDialog = function (eltId) { $("#" + eltId).dialog({ autoOpen: false, width: 610, minWidth: 610, height: 450, minHeight: 200, modal: true, resizable: false, draggable: false, }); }; Everything works just fine in Firefox, Safari, and Chrome. However, in IE 8 when the dialog is opened only the div.ui-dialog-titlebar is visible -- the div.ui-dialog-contents are not. The problem seems to be that while in the modern browsers, the div.ui-dialog-contents has a specific height set in its style, i.e. after opening the dialog, the resulting HTML is: <div class="ui-dialog-content ui-widget-content" id="invite-friends-dialog" style="width: auto; min-height: 198px; height: 448px">...</div> while in IE8 the height style attribute is set to zero, and the resulting HTML is: <div class="ui-dialog-content ui-widget-content" id="invite-friends-dialog" style="min-height: 0px; width: auto; height: 0px">...</div> What do I need to do to get the height (and min-height) style attributes set correctly?

• Replacing content with jquery.

  - by BillZ

  I am loading a movie into a overlay. My problem is that when I close the div overlay the movie continues to play. I do not control the code on the move side it is imported via a script tag which then opens in a iframe. I am able to remove the content of the of the div and then the movie stops playing. Then of course when the user opens the div again the movie is gone. My current thinking was that I could simply replace the script tag with one just like it but the outcome of that is that there is nothing there. I have been using jquery. Thanks -- script -- $(document).ready(function() { $("#closeModal2").click(function() { $("#movieContainer").html("<script src='http://www.accelacast.com/programs/launch.js'/>"); }); }); -- html -- <div id="movieContainer"> <script id="movieTag" language='JavaScript' src='http://www.accelacast.com/programs/launch.js'/> </div> On a side note. I tried replacing the src attribute of the script tag with no luck. I was able to replace the src of a image though. Is it not possible to effect the src attribute of script? Thanks

• accessing widgets inside a GWT element

  - by flyingcrab

  I want to access the text elements inside this textbox in GWT from the main method (where I call it like this) DialogBox aBox = newCandidatePop.buildNewElecPopup(); aBox.center(); aBox.getWidget(); MiscUiTools.newCandidateHandler(aBox.firstName, aBox.surName); in newCandidateHandler i want to attach a click handler to the two text boxes However, the above doesnt quite work - I cant get access to the aBox.firstName elements because they are static methods -- I am wondering what is best practice, how would you code something like this up? static TextBox firstName = new TextBox(); static TextBox surName = new TextBox(); static DialogBox box; // public newCandidatePop() { // box = buildNewElecPopup(); // } static public DialogBox buildNewElecPopup() { DialogBox box = new DialogBox(); box.setAutoHideEnabled(true); box.setText("Add a New Candidate"); box.setAnimationEnabled(true); box.setGlassEnabled(true); Grid dialogGrid = new Grid(2, 3); dialogGrid.setPixelSize(250 , 125); dialogGrid.setCellPadding(10); dialogGrid.setWidget(0, 0, new HTML("<strong>First Name</strong>")); dialogGrid.setWidget(0, 1, firstName); dialogGrid.setWidget(1, 0, new HTML("<strong>Surname</strong>")); dialogGrid.setWidget(1, 1, surName); box.add(dialogGrid); return box; }

• onSubmit returning false is not working

  - by StuckOnSubmit

  I'm completely confused ... I'd swear this was working yesterday ... I woke up this morning and all my forms stopped to work in my project. All the forms have a "onsubmit" to a function that returns false since it's an ajax call, so the form is never sent. After a lot of tests, I simplified the question to this piece of code: <html> <head> <script type="text/javascript"> function sub() { alert ("MIC!"); return false; } </script> </head> <body> <form method = "post" id = "form1" onsubmit = "return sub()"> input: <input type="text" name="input1" > <a href="#" onClick="document.getElementById('form1').submit();">button</a> </form> </body> </html> I would swear that this works perfectly, but today is nor working :D Why if I press the button the form is sent ? I know it's a total newbie question, but I'm stuck Thank you !

• Finding the right terminology for a dictionary table

  - by Karl Forner

  My concern is about what I currently call "dictionary tables", that are database tables containing a list of controlled vocabulary. Let's use an example: Suppose you have a table User containing fields: user_id : primary key first_name last_name user_type_id : foreign key to the UserType table and another table UserType with just two fields: user_type_id : primary key name : the name/value of a particular type of user. For instance, the UserType table may contain (1, Administrator), (2, PowerUser), (3, Normal)... My question is: what is the canonical term for a table like UserType, that only contains a list of (dictinct) words. I want to publish some code that help managing this kind of tables, but first I have to name them ! Thanks for your help. Current state of thought: For now I feel Lookup Tables is a good term. It is also used with the same meaning in these posts: http://dbix-class.35028.n2.nabble.com/RFC-Component-for-Lookup-tables-td3504085.html http://tonyandrews.blogspot.de/2004/10/otlt-and-eav-two-big-design-mistakes.html Lookup Tables Best Practices: DB Tables... or Enumerations The only problem is that lookup table is also sometimes used to name a junction table.

• Action Mailer: How do I render dynamic data in an email body that is stored in the database?

  - by Brandon Toone

  I have Action Mailer setup to render an email using the body attribute of my Email model (in the database). I want to be able to use erb in the body but I can't figure out how to get it to render in the sent email message. I'm able to get the body as a string with this code # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # pulls the email body and passes a string to the template views/user_mailer/customer_email.text.html.erb body :msg => email.body end I came across this article http://rails-nutshell.labs.oreilly.com/ch05.html which says I can use render but I'm only able to get render :text to work and not render :inline # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # body :msg => email.body body :msg => (render :text => "Thanks for your order") # renders text and passes as a variable to the template # body :msg => (render :inline => "We shipped <%= Time.now %>") # throws a NoMethodError end

• How to return value using ajax

  - by Priyanka

  Hello. I have Ajax file in which code has written to accept values form user and then these values are taken in a Ajax function as follows: $(document).ready(function(){ $("#newsletterform").validate(); $('#Submit').click(function(){ var name = $('#newsletter_name').val(); var email = $('#newsletter_email').val(); sendValue(email,name); }); }); The function for paasing values and getting values from other file: function sendValue(str,name){ $.post( "newsletter/subscribe.php", //Ajax file { sendValue: str, sendVal: name }, function(data2){ $('#display').html(data2.returnValue); }, //How you want the data formated when it is returned from the server. "json" ); } and these values are passed to another file called "subscribe.php" in which insertion code to database is written and again I return the value to my first ajax function as follows: echo json_encode(array("returnValue"=$msg)); The msg is ging to contain my message to be displayed. But now, this works fine on localhost, I get the return values nad message properly but when I upload it on server this gives me an error as: data2 is null [Break on this error] $('#display').html(data2.returnValue); This only gives error for return value but insertion, sending mail functionality works fine. Please provide me with a good solution wherein I can be able to get back the return values without any error. Thanks in advance.

• CSS: div text wrap around floated div

  - by Thildemar

  I am trying to create a site that has a fixed width content div and a floating div in the blank space on the right of the page, like so: <html> <div style="width:150px;float:right;border:thin black solid"> Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam.</div> <div style="width:400px"> Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat. Duis autem vel eum iriure dolor in hendrerit in vulputate velit esse molestie consequat, vel illum dolore eu feugiat nulla facilisis at vero eros et accumsan et iusto odio dignissim qui blandit praesent luptatum zzril delenit augue duis dolore te feugait nulla facilisi. </div> </html> This works fine, but when the page is re sized too small either the left div jumps down or the text within it does not start wrapping around the right div until its about halfway through it. I would like the test within the left div to wrap around the float is the page width is too small. What am I missing??

• ObjectiveFlickr - how to call getSizes on a photo ID not known until the response?

  - by Jonathan Cohen

  Hi guys, I'm building a free music instrument iPhone app with the Flickr API and ObjectiveFlickr.A random photo from the interestingness list is displayed in the background, but I can't center it without knowing its size. (so I can reset the UIWebView frame) I've been researching this for awhile, and if the answer is super easy, please have some mercy on a noob - it's my first time playing with a web service API. =) Since I don't know the photo ID until after I receive the response from the interestingness feed, how would I call flickr.photo.getSizes on the response? This is what I have so far: - (void)flickrAPIRequest:(OFFlickrAPIRequest *)inRequest didCompleteWithResponse:(NSDictionary *)inResponseDictionary{ int randomResponse = arc4random() % 49; photoDict = [[inResponseDictionary valueForKeyPath:@"photos.photo"] objectAtIndex:randomResponse]; NSString *photoID = [photoDict valueForKeyPath:@"id"]; NSLog(@"%@",photoID); NSURL *photoURL = [flickrContext photoSourceURLFromDictionary:photoDict size:OFFlickrMediumSize]; NSString *htmlSource = [NSString stringWithFormat: @"<html>" @"<head>" @" <style>body { margin: 0; padding: 0; } </style>" @"</head>" @"<body>" @"<img src=\"%@\" />" @"</body>" @"</html>" , photoURL]; [webView loadHTMLString:htmlSource baseURL:nil]; }

• need to add secure ftp file upload area to a client's website

  - by user346602

  This is a variation on a previous question as I am having tons of trouble finding answers in all my relentless online searches. Am designing a website for an architecture firm. They want their clients to be able to upload files to them, through a link on their site, via ftp. They also want to have a sign in for their clients, and ensure the uploads are secure. I can figure out how to make a form that has a file upload area - but just don't understand the ftp and the secure part... I understand html, css and a bit of JQuery; the rest is still very challenging to me. Have found something called net2ftp that claims to do what I'm looking for - but the even the installation instructions (for administrators, here: http://www.net2ftp.com/help.html) confuse me. Do I need a MySQL database? Where do I put in Admin password they refer to? It goes on... Is there anything "easier" out there that anyone knows of? I have read that I should be Googling "file managers" - but don't know if these can be embedded in a client's website. I even need to understand of what happens to said file, and where it ends up, when client clicks the upload link. Oh - I am so in over head on this one.

• Clearly defined Rails routing problem - undefined method for Nil:NilClass

  - by sscirrus

  Guys and girls, I have been working on this problem for a while but still no joy. This is my second question within this general area, because the last question was getting too long and this is now more well-defined. Summary of the Problem: I am loading a page for my customers and I get error: undefined method 'name' for Nil:NilClass My Code #Link on views/users/show.html.erb: <%= link_to "Customer Account", :action => "home", :controller => "customers", :id => @user.user_type_id %> #Regular Route: map.connect 'customers/home/:id', :controller => 'customers', :action => 'home' #Rake Routes, first entry: /customers/home/:id :controller=>:"customers", :action=>"home" #Customers Controller: def home render :layout => 'home' @customer = Customer.find(params[:id]) @user = @current_user_session.user flash[:error] = "Customer not found" and return unless @customer @jobs = @customer.jobs end #views/customers/home.html.erb: <%= @customer.name %> I have absolutely no idea why this seemingly clear sequence of events is resulting in a NilClass. Search the console for Customer.find(2) returns the correct customer. What is this noob missing? Thank you very much.

• No route matches when trying to edit

  - by mmichael

  Here's the scoop: I've created a test app that allows users to create ideas and then add "bubbles" to these ideas. Currently, a bubble is just text. I've successfully linked bubbles to ideas. Furthermore, when a user goes to view an idea it lists all of the bubbles attached to that idea. The user can even delete the bubble for any given idea. My problem lies in editing bubbles. When a user views an idea, he sees the idea's content as well as any bubbles for that idea. As a result, I've set all my bubble controls (editing and deleting) inside the ideas "show" view. My code for editing a bubble for an idea is <%= link_to 'Edit Bubble', edit_idea_bubble_path %>. I ran rake routes to find the correct path for editing bubbles and that is what was listed. Here's my error: No route matches {:action=>"edit", :controller=>"bubbles"} In my bubbles controller I have: def edit @idea = Idea.find(params[:idea_id]) @bubble = @idea.bubbles.find(params[:id]) end def update @idea = Idea.find(params[:idea_id]) @bubble = @idea.bubbles.find(params[:id]) respond_to do |format| if @bubble.update_attributes(params[:bubble]) format.html { redirect_to(@bubble, :notice => 'Bubble was successfully updated.') } format.xml { head :ok } else format.html { render :action => "Edit" } format.xml { render :xml => @bubble.errors, :status => :unprocessable_entity } end end end To go a step further, I have the following in my routes.rb file resources :ideas do resources :bubbles end So far everything seems to function except when I try to edit a bubble. I'd love some guidance. Thanks!

• C#/.NET library for source code formatting, like the one used by Stack Overflow?

  - by Lasse V. Karlsen

  I am writing a command line tool to convert Markdown text to html output, which seems easy enough. However, I am wondering how to get nice syntax coloring for embedded code blocks, like the one used by Stack Overflow. Does anyone know either: What library StackOverflow is using or if there's a library out there that I can easily reuse? Basically it would need to have some of the same "intelligence" found in the one that Stack Overflow uses, by basically doing a best-attempt at figuring out the language in use to pick the right keywords. Basically, what I want is for my own program to handle a block like the following: if (a == 0) return true; if (a == 1) return false; // fall-back Markdown Sharp, the library I'm using, by default outputs the above as a simple pre/code html block, with no syntax coloring. I'd like the same type of handling as the formatting on Stack Overflow does, the above contains blue "return" keywords for example. Or, hmm, after checking the source of this Stack Overflow page after adding the code example, I notice that it too is formatted like a simple pre/code block. Is it pure javascript-magic at works here, so perhaps there's no such library? If there's no library that will automagically determine a possible language by the keywords used, is there one that would work if I explicitly told it the language? Since this is "my" markdown-commandline-tool, I can easily add syntax if I need to.
