  • Is Prince the best way to PDF in Ruby on Rails?

    - by Angela
    After several Google searches, it appears that the way to create PDF's in Rails from HTML and CSS (versus a new markup language) is to use Prince. With licensing at $3800 for my non-big-commercial app, I'm wondering if this is, in fact, consensus or people have an alternative they can share the what's and how's.

  • Issues with Apache redirect to www-prefixed URL

    - by lamp_scaler
    I have a website with domain mysite.com. I would like to have it so that if a user types in "mysite.com" it will redirect to "www.mysite.com". Additionally, "mysite.com/subdir" will also redirect to "www.mysite.com/subdir". I've looked and made changes with vhosts and also rewrites, but it's not working for the "mysite.com/subdir"-"www.mysite.com/subdir" case. Every time I type in "mysite.com/subdir", it will redirect to "www.mysite.com". Only "www.mysite.com/subdir" works. Not sure how to troubleshoot this. I turned on rewrite logs and didn't see anything obvious, yet. This is my config files so far. Please let me know what I'm missing. Thanks! FYI: I'm using CentOS 5.4, nginx 1.2.0 on top of Apache 2.2.3.

  • Included php file calling Javascript function

    - by Illes Peter
    Hi there! Here's the deal. I've got index.php which links to an internal JS file in it's header. index.php then includes another .php file, which outputs this: + add file. addFile() is a Javascript function defined in the external JS file. By doing this nothing happens, the included php does not "see" the JS function. Encapsulating the JS in the included PHP makes it all work. But I don't want to do it that way. Any ideas? EDIT: here's the source <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Archie</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <link rel="stylesheet" href="/screen.css" type="text/css" media="screen"/> <script src="/lib/js/archie.js" type="text/javascript"></script> </head> <body> ... ... //included php starts here <form action="/lib/course.php" method="post"> <fieldset> <div id="addFileLocation"></div> <a href="#" onClick="addFile()">+ add file</a> <input type="hidden" id="addFileCount" value="0"/> </fieldset> </form> //ends here ... ... </body> </html> and the js: <script type="text/javascript"> //Dynamically add form fields //add file browser function addFile() { var location = document.getElementById('addFileLocation'); var num = document.getElementById('addFileCount'); var newnum = (document.getElementById('addFileCount').value -1)+ 2; num.value = newnum; var newname = 'addFile_'+newnum; var newelement = document.createElement('input'); newelement.setAttribute('name',newname); newelement.setAttribute('type','file'); location.appendChild(newelement); } </script>

  • Creating a mobile version for my web app in CodeIgniter

    - by KeyStroke
    Hi there, I'm using CodeIgniter to develop a new web app, and I'd like to create a mobile version that users get redirect to when they visit it from their phones. The mobile version of the app should have a different flow, so swapping CSS/HTML files in the code is not an option for me since the mobile version and the web version will handle things differently in their Controllers and Views, while sharing the same Models. Anyway how I could do this efficiently? Your help is much appreciated. :)

  • How can I write directly to my Zune HD hard drive?

    - by iamgoat
    When syncing photos to the Zune HD it resizes them down to a much lower resolution which means I cannot load a high res picture on it (comic book) and zoom in to read it. This defeats the whole purpose of having a zoom feature. There is a registry hack you can make to get the Zune to display under My Computer. Then if you killed the zune process while it's syncing you'd be able to access it like a hard drive and copy files to it. It seems like the more recent firmware and/or Zune software version now prevents this. How can I treat it like an HDD and copy files to it? I simply want to take my original pictures folder and copy it over the low resolution versions the Zune software resized it to. An alternative option would be to remove the hard drive from it and see if I can connect it to a computer directly, but I just got this and don't want to disassemble it yet. Note to Microsoft: Why do you allow me to set the encoding quality of music, but not photos?

  • What is a better way to convert a simple sinatra app to static html pages?

    - by dimus
    A friend of mine asked to create a static website and I found that making such site using Sinatra is a pure joy. I just wrote all my routes like this: get '/index.html' do haml :index end get '/app.css' do sass :app end .... So I was able to use layouts, and haml and sass to put site together quickly. To create the static site I used wget -r -l2 http://localhost:4567 Which did work pretty well, but I imagine there is a better way to create a static site from a Sinatra code?

  • How do I display a jquery dialog box before the entire page is loaded?

    - by obarshay
    On my site a number of operations can take a long time to complete. When I know a page will take a while to load, I would like to display a progress indicator while the page is loading. Ideally I would like to say something along the lines of: $("#dialog").show("progress.php"); and have that overlay on top of the page that is being loaded (disappearing after the operation is completed). Coding the progress bar and displaying progress is not an issue, the issue is getting a progress indicator to pop up WHILE the page is being loaded. I have been trying to use JQuery's dialogs for this but they only appear after the page is already loaded. This has to be a common problem but I am not familiar enough with JavaScript to know the best way to do this. Here's simple example to illustrate the problem. The code below fails to display the dialog box before the 20 second pause is up. I have tried in Chrome and Firefox. In fact I don't even see the "Please Wait..." text. Here's the code I am using: <html> <head> <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" /> <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.dialog.js"></script> </head> <body> <div id="please-wait">My Dialog</div> <script type="text/javascript"> $("#please-wait").dialog(); </script> <?php flush(); echo "Waiting..."; sleep(20); ?> </body> </html>

  • Advantages/disadvantages of browser-based interface vs. graphics

    - by Josh
    Hello everyone, I'm in the design phase for a desktop-based application. Because of the nature of this particular application, I believe it would benefit greatly from a web-based approach (i.e., allowing a user to interface with the application through a browser running in kiosk mode) in order to leverage the simplicity of HTML/CSS/JS and the availability of many great JS interface plugins. Does taking this approach (rather than coding in a native or cross-platform graphics library) come with any gotchas?

  • Methodology to understanding JQuery plugin & API's developed by third parties

    - by Taoist
    I have a question about third party created JQuery plug ins and API's and the methodology for understanding them. Recently I downloaded the JQuery Masonry/Infinite scroll plug in and I couldn't figure out how to configure it based on the instructions. So I downloaded a fully developed demo, then manually deleted everything that wouldn't break the functionality. The code that was left allowed me to understand the plug in much greater detail than the documentation. I'm now having a similar issue with a plug in called JQuery knob. http://anthonyterrien.com/knob/ If you look at the JQuery Knob readme file it says this is working code: <input type="text" value="75" class="dial"> $(function() { $('.dial') .trigger( 'configure', { "min":10, "max":40, "fgColor":"#FF0000", "skin":"tron", "cursor":true } ); }); But as far as I can tell it isn't at all. The read me also says the Plug in uses Canvas. I am wondering if I am suppose to wrap this code in a canvas context or if this functionality is already part of the plug in. I know this kind of "question" might not fit in here but I'm a bit confused on the assumptions around reading these kinds of documentation and thought I would post the query regardless. Curious to see if this is due to my "newbi" programming experience or if this is something seasoned coders also fight with. Thank you. Edit In response to Tyanna's reply. I modified the code and it still doesn't work. I posted it below. I made sure that I checked the Google Console to insure the basics were taken care of, such as not getting a read-error on the library. <!DOCTYPE html> <meta charset="UTF-8"> <title>knob</title> <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/hot-sneaks/jquery-ui.css" type="text/css" /> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js" charset="utf-8"></script> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.min.js"></script> <script src="js/jquery.knob.js"></script> <div id="button1">test </div> <script> $(function() { $("#button1").click(function () { $('.dial').trigger( 'configure', { "min":10, "max":40, "fgColor":"#FF0000", "skin":"tron", "cursor":true } ); }); }); </script>

  • HTTP caching confusion

    - by Keith
    I'm not sure whether this is a server issue, or whether I'm failing to understand how HTTP caching really works. I have an ASP MVC application running on IIS7. There's a lot of static content as part of the site including lots of CSS, Javascript and image files. For these files I want the browser to cache them for at least a day - our .css, .js, .gif and .png files rarely change. My web.config goes like this: <system.webServer> <staticContent> <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" /> </staticContent> </system.webServer> The problem I'm getting is that the browser (tested Chrome, IE8 and FX) doesn't seem to be caching the files as I'd expect. I've got the default settings (check for newer pages automatically in IE). On first visit the content downloads as expected HTTP/1.1 200 OK Cache-Control: max-age=86400 Content-Type: image/gif Last-Modified: Fri, 07 Aug 2009 09:55:15 GMT Accept-Ranges: bytes ETag: "3efeb2294517ca1:0" Server: Microsoft-IIS/7.0 X-Powered-By: ASP.NET Date: Mon, 07 Jun 2010 14:29:16 GMT Content-Length: 918 <content> I think that the Cache-Control: max-age=86400 should tell the browser not to request the page again for a day. Ok, so now the page is reloaded and the browser requests the image again. This time it gets an empty response with these headers: HTTP/1.1 304 Not Modified Cache-Control: max-age=86400 Last-Modified: Fri, 07 Aug 2009 09:55:15 GMT Accept-Ranges: bytes ETag: "3efeb2294517ca1:0" Server: Microsoft-IIS/7.0 X-Powered-By: ASP.NET Date: Mon, 07 Jun 2010 14:30:32 GMT So it looks like the browser has sent the ETag back (as a unique id for the resource), and the server's come back with a 304 Not Modified - telling the browser that it can use the previously downloaded file. It seems to me that would be correct for many caching situations, but here I don't want the extra round trip. I don't care if the image gets out of date when the file on the server changes. There are a lot of these files (even with sprite-maps and the like) and many of our clients have very slow networks. Each round trip to ping for that 304 status is taking about a 10th to a 5th of a second. Many also have IE6 which only has 2 HTTP connections at a time. The net result is that our application appears to be very slow for these clients with every page taking an extra couple of seconds to check that the static content hasn't changed. What response header am I missing that would cause the browser to aggressively cache the files? How would I set this in a .Net web.config for IIS7? Am I misunderstanding how HTTP caching works in the first place?

  • Cannot delete flash9.ocx

    - by Kara Marfia
    Some kinda voodoo, indeed. Bought a new boot drive, and it's time to use the old drive for data. I thought I'd save some time by just wiping the unneeded system folders, instead of backing up, formatting, and restoring. Wups! I have a single Adobe file that absolutely will not be deleted. G:\Windows\SysWOW64\Macromed\Flash\flash9.ocx - though it may have started with a different file name. I'm able to rename it, oddly enough. To be clear, the drive is currently plugged in externally. So I can boot the computer, plug this drive in afterward, and immediately attempt to delete. "File in use" box reads "the action can't be completed because the file is open in another program". I'd format at this point, but it's my white whale, and I have to know if Adobe has inserted some nasty little registry hack - or whatever it is - making this impossible. Since I'm sure it'll come up, I've taken ownership of the file - and this was the trick preventing me from deleting anything else on the drive - full rights on the file permissions, you name it, I've fiddled with the file itself. I'm about to try uninstalling flash from the system drive, in case that aligns the planets properly. Sometimes I wish I were less stubborn, and could just format already.

For example, there are 3 detail table for a master table, and I want to use 3 different tabs for editing that 3 detail tables in the 'edit' page for the master table. Thank you in advance!

  • Hibernate between OS X and Bootcamp Win 7

    - by Willem
    Wouldn't it be great if someone wrote a guide or an app which allowed you to switch instantly between OS X and Windows using Hibernate in both OS:s? Windows 7 already has an option "Hibernate" which allows you to boot back to your OS X partition, but OS X does not exactly offer the same. However, there are possibilities here. It seems that the recent Mac's have 3 different kinds of sleeping mode: Sleep: Low power consumption, RAM still active. Legacy Safe Sleep: No power consumption(?), writes RAM to disk and shuts down (is this the same as Hibernate?) Safe Sleep: Writes RAM to disk and enters sleep mode. If battery level drops too low it goes into Hibernate (is this Hibernate the same as #2 in this list? This is the Hibernate I will be referring to int he rest of this post) It seems that I am unable to force my MacBook Pro (Late 2011) OS X 10.7.3 into a true hibernate using either command line or apps that are supposed to do this. I believe the Mac should show that white loading bar whilst waking up if it was truly put into hibernate (which it does not). But I can get this white bar to show by letting my battery level drop to 0% so there is obviously a system function for it (obviously, duh! :). When Win 7 goes into hibernate it shuts down completely and you can then boot into OS X on startup. On OS X however, hibernate forces you to wake up into OS X. Can you hack this so that you're allowed to select boot partition after OS X hibernates? Would it be possible to use the true hibernate system functionalities of Win 7 and OS X to create a kind of instant switching between the two? Imagine this on a quick SATA-3 SSD like my 180GB Intel 520. Thanks / Willem

  • SharePoint Permissions - Repeated Login Boxes

    - by Ryan Smith
    I have a SharePoint site that is locked down through standard Windows permissions. I keep getting an repeated login box prompt, and it appears that it has to do with the Themes images and the CSS style sheets. Where do I need to update permissions so that these files have the same permissions as the rest of the site and the user only needs to login once? Thanks.
