• LAMP stack on home computer as a public web server

  - by Scott

  So I'm using this website: http://www.howtoforge.com/ubuntu_debian_lamp_server to setup LAMP on my Ubuntu Virtual Machine. Here is my question though, This will enable me to program and test through localhost. How can I set this up so anyone on the web can access my .php pages from any Internet capable device, and they will still interact with my local database, etc?

• Ruby proc vs lambda in initialize()

  - by Jimmy Chu

  I found out this morning that proc.new works in a class initialize method, but not lambda. Concretely, I mean: class TestClass attr_reader :proc, :lambda def initialize @proc = Proc.new {puts "Hello from Proc"} @lambda = lambda {puts "Hello from lambda"} end end c = TestClass.new c.proc.call c.lambda.call In the above case, the result will be: Hello from Proc test.rb:14:in `<main>': undefined method `call' for nil:NilClass (NoMethodError) Why is that? Thanks!

• Codeigniter: Checklist for new users & logistics of app

  - by Kevin Brown

  I'm developing my first web-app, and I'm working through logistics. New users (At first login) need to complete a few things before they can use the app fully. For example, they need to complete their profile before they can move on to step 2, which is taking a test. What's the best way to go about creating a "new-user" checklist? I want it to be as simple as possible, coding wise, and as easy as possible for the user.

Any ideas why this is happening?

• How to open document that contains AutoOpen macro with powershell?

  - by grom

  My current powershell script: $document = "C:\\test.doc" $word = new-object -comobject word.application $word.Visible = $false $word.DisplayAlerts = "wdAlertsNone" $word.AutomationSecurity = "msoAutomationSecurityForceDisable" $doc = $word.Documents.Open($document) $word.ActivePrinter = "\\http://ptr-server:631\pdf-printer" $background = $false $doc.PrintOut([ref]$background) $doc.close([ref]$false) $word.quit() But it results in an alert box "The macros in this project are disabled. Please refer to the online help or documentation of the host application to determine how to enable macros." How can I open the document without it running the AutoOpen macro or displaying any sort of dialog prompt?

• JUnit Rule TemporaryFolder

  - by Jeff Storey

  I'm creating a TemporaryFolder using the @Rule annotation in JUnit 4.7. I've tried to create a new folder that is a child of the temp folder using tempFolder.newFolder("someFolder") in the @Before (setup) method of my test. It seems as though the temporary folder gets initialized after the setup method runs, meaning I can't use the temporary folder in the setup method. Is this correct (and predictable) behavior? thanks, Jeff

• jQuery and iterating on JSON objects.

  - by The Devil

  Hey everybody, I'm currently trying to figure out how can I iterate over all of the objects in an JSON response. My object may have endless sub objects and they may also have endless sub objects. { "obj1" : { "obj1.1" : "test", "obj1.2" : { "obj1.1.1" : true, "obj1.1.2" : "test2", "obj1.1.3" : { ... // etc } } } } I was just wondering if there is a out of the box script that can handle such kind of objects? Thanks in advance, The Devil

• How to "enable" HTML5 elements in IE that were inserted by AJAX call?

  - by Gidon

  IE does not work good with unknown elements (ie. HTML5 elements), one cannot style them , or access most of their props. Their are numerous work arounds for this for example: http://remysharp.com/2009/01/07/html5-enabling-script/ The problem is that this works great for static HTML that was available on page load, but when one creates HTML5 elements afterward (for example AJAX call containing them, or simply creating with JS), it will mark these newly added elements them as HTMLUnknownElement as supposed to HTMLGenericElement (in IE debugger). Does anybody know a work around for that, so that newly added elements will be recognized/enabled by IE? Here is a test page: <html><head><title>TIME TEST</title> <!--[if IE]> <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> </head> <body> <time>some time</time> <hr> <script type="text/javascript"> $("time").text("WORKS GREAT"); $("body").append("<time>NEW ELEMENT</time>"); //simulates AJAX callback insertion $("time").text("UPDATE"); </script> </body> </html> In IE you will see the: UPDATE , and NEW ELEMENT. In any other modern browser you will see UPDATE, and UPDATE Solution Using the answer provided I came up with the following piece of javascript to HTML5 enable a whole bunch of elements returned by my ajax call: (function ($) { jQuery.fn.html5Enable = function () { if ($.browser.msie) { $("abbr, article, aside, audio, canvas, details, figcaption, figure, footer, header, hgroup, mark, menu, meter, nav, output, progress, section, summary, time, video", this).replaceWith(function () { if (this.tagName == undefined) return ""; var el = $(document.createElement(this.tagName)); for (var i = 0; i < this.attributes.length; i++) el.attr(this.attributes[i].nodeName, this.attributes[i].nodeValue); el.html(this.innerHtml); return el; }); } return this; }; })(jQuery); Now this can be called whenever you want to append something: var el = $(AJAX_RESULT_OR_HTML_STRING); el.html5Enable(); $("SOMECONTAINER").append(el); See http://code.google.com/p/html5shiv/issues/detail?id=4 for an explanation about what this plugin doesn't do.

• How to integer-divide round negative numbers *down*?

  - by Conrad Albrecht

  Seems like whenever I divide a negative int by a positive int, I need it to round down (toward -inf), not toward 0. But both C# and C++ round toward 0. So I guess I need a DivideDownward() method. I can write it in a few lines with a test for negative and so on, but my ideas seem klugey. So I'm wondering if I'm missing something and if you have an "elegant" way to round negative division downward.

• Float: left not showing up after a certain point.

  - by Bobby K

  http://test.jptgraphics.com/products?cat=APPAREL This works fine in Safari but shows incorrectly in the latest version of Firefox ( was fine in 3.5) and in some versions of IE. In the middle column the product thumbnails drop down below when the 'float: left;' parameter is used. It is as if it is being escaped by a tag from that point forward no 'float: left's work and all the items are centered moving forward.

• How to create constant NSString by concatenating strings in Obj-C ?

  - by eric-morand

  Hi guys, I'm trying to instanciate a constant NSString by concatanating other NSString instances. Here is what I'm doing in my implementation file : static NSString *const MY_CONST = @"TEST"; static NSString *const MY_CONCATENATE_CONST = [NSString stringWithFormat:@"STRING %@", MY_CONST]; It leads to the following compilation error : Initializer element is not constant I suppose this is because stringWithFormat doesn't return a constant NSString, but since there is no other way to concatenate strings in Obj-C, what am I supposed to do ? Thanks for your help, Eric.

  How do I bind a function to the HTML5 localStorage change event using jQuery? $(function () { $(window).bind('storage', function (e) { alert('storage changed'); }); localStorage.setItem('a', 'test'); }); I've tried the above but the alert is not showing. Update: It works in Firefox 3.6 but it doesn't work in Chrome 8 or IE 8 so the question should be more 'How to bind to localStorage change event using jQuery for all browsers?'

• Issue with deserialization of a static property in .Net

  - by Punit Singhi

  I have a class called Test which has four public properties and one of them is static. the problem is after deserialization the static property contains null value. i have debugged the code and found that at server side it contains the value which is a collection , but at client side it becomes null after deserialization. i know static members doesn't serialize and deserialize so obviously it should contain the value.
