  • Cross browser (chrome/firefox) trying to get top-pos defined in percentage as pixels

    - by Cinaird
    I have a problem whit cross browser output, I'm trying to get the top and left css attribute of a div, but firefox gives me the exact pixel position and Chrome give me the percentage. Example: http://web.cinaird.se/pdf/test.htm CSS #mix{ position:absolute; top: 10px; left: 45%; background-color:#f0f; } jQuery css top: " + $("#mix").css("top") + " <br/>css left: " + $("#mix").css("left") Output Firefox (and IE8): css top: 10px css left: 267.3px Chrome: css top: 10px css left: 45% is there any way to get the same result for both (all) browsers? I would prefer to get a pixel value without any major calculation

  • Is there an implementation of rapid concurrent syntactical sugar in scala? eg. map-reduce

    - by TiansHUo
    Passing messages around with actors is great. But I would like to have even easier code. Examples (Pseudo-code) val splicedList:List[List[Int]]=biglist.partition(100) val sum:Int=ActorPool.numberOfActors(5).getAllResults(splicedList,foldLeft(_+_)) where spliceIntoParts turns one big list into 100 small lists the numberofactors part, creates a pool which uses 5 actors and receives new jobs after a job is finished and getallresults uses a method on a list. all this done with messages passing in the background. where maybe getFirstResult, calculates the first result, and stops all other threads (like cracking a password)

  • Transform PDF to HTML, keep layout

    - by Tgr
    What methods are there to transform a PDF to HTML? It could be anything - online service, software, library. (Opensource preferred. In the last case, php or python would be preferred.) It has to keep the original layout (including page numbers, footnotes and such), keep the images (combining them to one single background image per page is acceptable) and keep the links. It should preferably output valid XHTML and clean up PDF features such as ligatures, but if there is some post-processing required, I can live with that. Something with a clean, relatively semantic HTML output would be great. The closest one I found was zamzar.org, but it choked on links. (Also, the HTML output is an ugly heap of absolutely positioned divs and needs post-processing because of encoding problems.)

  • Is this a "valid" css image replacement technique?

    - by user278457
    I just came up with this, it seems to work in all modern browsers, I just tested it then on (IE8/compatibility, Chrome, Safari, Moz) HTML <img id="my_image" alt="my text" src="images/small_transparent.gif" /> CSS #my_image{ background-image:url('images/my_image.png'); width:100px; height:100px;} Pro's: image alt text is best-practice for accessibility/seo no extra HTML markup, and the css is pretty minimal too gets around the css on/images off issue where "text-indent" techniques hide text from low bandwidth users The biggest disadvantage that I can think of is the css off/images on situation, because you'll only send a transparent gif. I'd like to know, who uses images without stylesheets? some kind of mobile phone or something? I'm making some sites for clients in regional Australia (hundreds of km from the nearest city), where many users will be suffering from dial-up connections, and often outdated browsers too, so the "images off" issue is an important consideration. are there any other side effects with this technique that I haven't considered?

  • Home key press behaviour

    - by Arnab
    While developing a sample android application i have constructed two activities 1)Activity 1 2)Activity 2 Now Activity 2 is the foreground activity whereas Activity 1 is the background one. Now user presses Home key. The application(i.e. both the activities) dissappear. Now is we relaunch the application we see Activity 1 as the foreground activity. My question is: 1)Does the platform maintain any history entry when pressed home key? 2)How do we take the user to the last launch activity on relaunching the application?

  • How can I get a rails server to use the same databse that cucumber uses during a test?

    - by James
    The cucumber test first makes an entry in the database and posts a form to a second server. This second server does some processing in background and then hits the first app (where the test is being run) with some data that the cucumber test needs to know about. I've tried running the main server via script/server and script/server -e test while the cucumber test is running, but I can't seem to force the server to use the same database that cucumber is using when it runs its step definitions. That is, when the second server pushes some data to a controller in the main server, the main server doesn't know about any entries that cucumber has made in the database. How can I get cucumber and the main server to use the same database?

  • How can i see if dealloc is being called on a uikit object, or any object not created by myself

    - by Gyozo Kudor
    I think i have an UIImage that has a higher retain count than it should have and i am probably leaking memory. I use this image as a thumbnail, to set a custom background to a uibutton. So the uibutton is holding a reference to it and so do i. But instead of 2, the retainCount is 3. Do i have to create a custom UIImage derived class and override dealloc if I want to place a log message there and then change the class used from UIImage to my class, or is there an easier way. Thanks in advance.

  • Parallel Assignment operator in Ruby

    - by Bragaadeesh
    Hi, I was going through an example from Programming in Ruby book. This is that example def fib_up_to(max) i1, i2 = 1, 1 # parallel assignment (i1 = 1 and i2 = 1) while i1 <= max yield i1 i1, i2 = i2, i1+i2 end end fib_up_to(100) {|f| print f, " " } The above program simply prints the fibonacci numbers upto 100. Thats fine. My question here is when i replace the parallel assignment with something like this, i1 = i2 i2 = i1+i2 I am not getting the desired output. My question here is, is it advisable to use parallel assignments? (I come from Java background and it feels really wierd to see this type of assignment) One more doubt is : Is parallel assignment an operator?? Thanks

  • What is the best way to manage application screens in SWT?

    - by parxier
    I'm creating a standalone SWT desktop application that has around 10 different screens (few wizards, help, forms, etc). Some elements on screen don't change at all (like header, background, etc) and there is a working area that changes depending on what is clicked, etc. What is the best way to manage application screens? Do I need to create all screen at startup and then show/hide them depending on what is clicked? Or do I need to create those screens dynamically? Also, I couldn't find any way to show/hide a Composite, do I need to dispose it and then create again? What is the best practice? I'm new to SWT developing outside of Eclipse so any help would be beneficial.

  • OOWrite is to LaTeX as OODraw is to?

    - by grimborg
    I'm looking for a tool to nicely generate single-page PDFs. My needs are: Able to put a PDF/EPS/... as a background Absolute positioning Able to define tables, lists Able to rotate blocks Reasonably easy syntax (will be used to automatically generate many similar looking documents) Easily usable from Python Free or very cheap In essence I'm looking for the tool X that is to OODraw/CorelDraw/... as LaTeX is to OOWrite/MS Word. I've looked at webkit2pdf and a headless OODraw, but both seem a bit of an overkill. XML-FO has some limitations such as not being able to predict how many pages your document spans. Reportlab is pricey. Any ideas? Thanks!

  • Jquery CPU usage

    - by nharry
    I am using Jquery to make an image scroll across my page horizontally. The only problem is that it uses a serious amount of cpu usage. Up to 100% on a single core laptop in firefox. What could cause this??? Jquery <script> jQuery(document).ready(function() { $(".speech").animate({backgroundPosition: "-6000px 0px"}, 400000, null); }); </script> CSS .speech { /*position:fixed;*/ top:0; left:0px; height:400px; width:100%; z-index:-1; background:url(/images/speech.png) -300px -500px repeat-x; margin-right: auto; margin-left: auto; position: fixed; } HTML <div class="speech"></div>

  • Does Windows 7 have a Kiosk Mode?

    - by Jordan
    I'm writing a Kiosk on a Windows 7 computer. The Kiosk is on a touch screen computer, that will not have a keyboard. The application is a WPF application running the .NET Framework version 3.5. I'm having problems with the progress bar task bar showing up (blinking) at the bottom of the screen. This unfortunately gives the user access to the background operating system. Is there someway to lock a full screen application window into the front of the screen without using it on-top-of-everything mode. Some sort of Kiosk mode, or some tool that was designed for this.

  • What's the usual term for a local IIS/web application with services?

    - by JBRWilkinson
    I've inherited a multi-technology project which comprises a Flash user interface contained in a web-browser-like host and has an ASP.NET piece which provides web services to the Flash UI, background/watchdog services plus a web application for administration of the system. Our transatlantic project conference calls are getting confusing due to the various terms people use to describe the ASP.NET piece. Indeed, ASP.NET has its' own project terminology including 'Web Site' and 'Web Application' to both of which one can add a 'Web Service'. Is there any commonly-used name for this ASP.NET multi-purpose project piece?

  • css opacity not working in IE7

    - by Alsciende
    I have this test page : http://jsfiddle.net/VWnm9/7/. The image is correctly faded on all my computers running IE6, 7 or 8, except for one computer that runs IE7 and doesn't fade the flower, even in noext mode. The page is : <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en"> <head> <style type="text/css"> body { background: blue; } img { filter: alpha(opacity=10); opacity: 0.1; } </style> </head> <body> <img src="http://upload.wikimedia.org/wikipedia/commons/c/c3/Extracted_pink_rose.png" /> </body> </html> Does anybody have an idea why?

  • Using an empty keystore password used to be possible?

    - by TomTasche
    When signing an apk after a long break from Android development I was surprised that I'm no longer able to enter an empty keystore password to unlock it. Is it just me or has this been possible before? If so, when did that change and how can I manage to unlock the keystore anyway? Some background: maybe I'm just crazy and didn't use an empty password for the keystore before, but the one and only possible password that I could have been using instead doesn't work either (I swear, there's no chance I'd have used another password!).

  • Pseudo Transparant images

    - by Samuel
    Hello World! For an assignment at university we program in a pretty unknown language Modula 2, which lacks major graphic support. I was wondering how to achieve a 'transparency' effect on images, i figured it would work like this: Create a 2D array for the background area of the image filled with the colours of the different pixels in that area, create another 2D array of the image with again the colours of every picture and than merge the pixel colours and draw the different "new colours" on their appropriate place. What i was wondering about: how do i merge the colours (hexadecimals) just: ( colour1 + colour2 ) / 2 ? Thanks for your help!!

  • is there any cross platform process manager tool

    - by lvlv
    I need a program that is able to launch a set of processes according to a schedule/configuration; the program would run in the background and restart the processes in case they crash. There are standard tools for this kind of task on both windows and unix - what I need is a cross platform program which could run on different operating systems using the same configuration. A portable C/C++ library which implements the basic functionality (i.e. create processes, signal process termination events and all that) would be ok too.

  • Finding an HTTP proxy that will intercept static resource requests

    - by pkh
    Background I develop a web application that lives on an embedded device. In order to make dev times sane, frontend development is done using apache serving static documents, with PHP proxying out to the embedded device for specifically configured dynamic resources. This requires that we keep various server-simulation scripts hanging around in source control, and it requires updating those scripts whenever we add a new dynamic resource. Problem I'd like to invert the logic: if the requested document is available in the static documents directory, serve it; otherwise, proxy the request to the embedded device. Optimally, I want a software package that will do this for me (for Windows or buildable on cygwin). I can deal with forcing apache to do it with PHP, but I'm unsure how to configure it to make it happen. I've looked at squid and privoxy, but neither of them seem to do what I want. Any ideas? I'd rather not have to roll my own.

  • C# Using singleton instead of a global static instance

    - by Farstucker
    I ran into a problem today and a friend recommended I use a global static instance or more elegantly a singleton pattern. I spent a few hours reading about singletons but a few things still escape me. Background: What Im trying to accomplish is creating an instance of an API and use this one instance in all my classes (as opposed to making a new connection, etc). There seems to be about 100 ways of creating a singleton but with some help from yoda I found some thread safe examples. ..so given the following code: public sealed class Singleton { public static Singleton Instance { get; private set; } static Singleton() { Instance = new Singleton(); } } How/Where would you instantiate the this new class and how should it be called from a separate class? Thanks for your help.

  • How to flush data in php and disconnect user but keep the script alive

    - by Rodrigo
    This is a trick question, while developing a php+ajax application i felt into some long queries, nothing wrong with them, but they could be done in background. I know that there's a way to just send a reply to user while throwing the real processing to another process by exec(), however it dosen't feels right for me, this might generate exploits and it's not pratical on making it compatible with virtual servers and cross platform. PHP offers the ob_* functions although they help on flushing the cache, but the user will keep connected until the script is running. I'm wondering if there's an alternate to exec to keep a script running after sending data to user and closing connection/thread with apache, or a less "dirty" way to have processing data sent to another script.

  • Preventing a Firefox Extension's load event from triggering across tabs

    - by lgomez
    Hi, I've been working on a Firefox extension that uses an iFrame to do some background scrapping. I have gone through a number of hoops to get it to trigger only once in the window/tab where it should but now when I open a different tab that tab triggers the load event. I found this: https://developer.mozilla.org/en/Code_snippets/Progress_Listeners but the snippets are not there. This was helpful before but doesn't solve the problem: https://developer.mozilla.org/en/Code_snippets/On_page_load More frustrating is that if there is this: https://developer.mozilla.org/En/Listening_to_events_on_all_tabs why should I worry about the normal event listener triggering in more than one tab? Any ideas or examples?

  • How can I create a simple message box in Python?

    - by Carson Myers
    I'm looking for the same effect as alert() in JavaScript. I wrote a simple web-based interpreter this afternoon using Twisted.web. You basically submit a block of Python code through a form, and the client comes and grabs it and executes it. I want to be able to make a simple popup message, without having to re-write a whole bunch of boilerplate wxPython or TkInter code every time (since the code gets submitted through a form and then disappears). I've tried tkMessageBox: import tkMessageBox tkMessageBox.showinfo(title="Greetings", message="Hello World!") but this opens another window in the background with a tk icon. I don't want this. I was looking for some simple wxPython code but it always required setting up a class and entering an app loop etc. Is there no simple, catch-free way of making a message box in Python?

  • Trying to create scrolling horizontal thumbnail navigation that hides on left side when not in use

    - by user346602
    Hi, I am trying recreate the following type of scrolling thumbnail navigation as described in the following tutorial: http://tympanus.net/codrops/2010/05/10/scrollable-thumbs-menu/ I require my thumbs to slide out horizontally from the left. I have amended the code to the best of my abilities, but I can't get it to work. (Think the problem is in the top third of the jquery). Here is what I have to date: HTML <ul class="menu" id="menu"> <li> <a href="#"></a> <div class="sc_menu_wrapper"> <div class="sc_menu"> <a href="#"><img src="images/gallery/1.jpg" alt=""/></a> <a href="#"><img src="images/gallery/2.jpg" alt=""/></a> <a href="#"><img src="images/gallery/3.jpg" alt=""/></a> <a href="#"><img src="images/gallery/4.jpg" alt=""/></a> <a href="#"><img src="images/gallery/5.jpg" alt=""/></a> </div> </div> </li> </ul> CSS /* Navigation Style */ ul.menu{ position: fixed; top: 0px; left:0px; width: 100%; } ul.menu li{ position:relative; width: 100% } ul.menu li > a{ position:absolute; top:300px; left:0px; width:40px; height:200px; background-color:#e7e7e8; } /* Thumb Scrolling Style */ div.sc_menu_wrapper { position: absolute; right: 0px; height: 220px; overflow: hidden; top: 300px; left:0px; visibility:hidden; } div.sc_menu { height: 200px; visibility:hidden; } .sc_menu a { display: block; background-color:#e7e7e8; } .sc_menu img { display: block; border: none; opacity:0.3; filter:progid:DXImageTransform.Microsoft.Alpha(opacity=30); } JQUERY $(function(){ // function to make the thumbs menu scrollable function buildThumbs($elem){ var $wrapper = $elem.next(); var $menu = $wrapper.find('.sc_menu'); var inactiveMargin = 220; // move the scroll down to the beggining (move as much as the height of the menu) $wrapper.scrollRight($menu.outerHeight()); //when moving the mouse up or down, the wrapper moves (scrolls) up or down $wrapper.bind('mousemove',function(e){ var wrapperWidth = $wrapper.width(); var menuWidth = $menu.outerWidth() + 2 * inactiveMargin; var top = (e.pageX - $wrapper.offset().right) * (menuWidth - wrapperWidth) / wrapperWidth - inactiveMargin; $wrapper.scrollRight(right+10); }); } var stacktime; $('#menu li > a').bind('mouseover',function () { var $this = $(this); buildThumbs($this); var pos = $this.next().find('a').size(); var f = function(){ if(pos==0) clearTimeout(stacktime); $this.next().find('a:nth-child('+pos+')').css('visibility','visible'); --pos; }; // each thumb will appear with a delay stacktime = setInterval(f , 50); }); /// on mouseleave of the whole <li> the scrollable area is hidden $('#menu li').bind('mouseleave',function () { var $this = $(this); clearTimeout(stacktime); $this.find('.sc_menu').css('visibility','hidden').find('a').css('visibility','hidden'); $this.find('.sc_menu_wrapper').css('visibility','hidden'); }); // when hovering a thumb, change its opacity $('.sc_menu a').hover( function () { var $this = $(this); $this.find('img') .stop() .animate({'opacity':'1.0'},400); }, function () { var $this = $(this); $this.find('img') .stop() .animate({'opacity':'0.3'},400); } ); }); Wondering if some eagle eye might be able to point out where I am going wrong. As my knowledge of JQuery is limited, I'm guessing it is in there. I really appreciate anyone taking the time to look this over. Thank you!

  • Swing: what to do when a GUI update takes too long and freezes other GUI elements?

    - by java.is.for.desktop
    Hello, everyone! I know that GUI code in Java Swing must be put inside SwingUtilities.invokeAndWait or SwingUtilities.invokeLater. This way threading works fine. Sadly, in my situation, the GUI update it that thing which takes much longer than background thread(s). More specific: I update a JTree with about just 400 entries, nesting depth is maximum 4, so should be nothing scary, right? But it takes sometimes one second! I need to ensure that the user is able to type in a JTextPane without delays. Well, guess what, the slow JTree updates do cause delays for JTextPane during input. It refreshes only as soon as the tree gets updated. I am using Netbeans and know empirically that a Java app can update lots of information without freezing the rest of the UI. How can it be done? NOTE 1: All those DefaultMutableTreeNodes are prepared outside the invokeAndWait. NOTE 2: When I replace invokeAndWait with invokeLater the tree doesn't get updated.

  • Faking user interaction on CMS

    - by Leocer
    I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.
