  • How can I set the Rails environment for my somewhat stand alone Ruby script?

    - by Nick
    I have a Ruby script in my Rails app that I use to load some data from Twitter. In the future I will make it an automatic background process, but for now I run it manually like: ruby /lib/twitter/twitterLoad.rb In order to use the Rails model classes and such, I have the following as the top line of the script: require "#{File.dirname(__FILE__)}/../../config/environment.rb" By default, the development environment is used. But, I'd like to be able to choose the production environment at some point. Update #1: The RAILS_ENV constant is getting set in the environment.rb file. So, I was able to put ENV['RAILS_ENV'] = 'production' at the very top (before the environment.rb) line and solve my problem somewhat. So, my new question is, can do pass in env vars through the command line?

I tried to put wmode outside embed tag - without result.

  • Execute 'stty raw' command in same terminal?

    - by Matt
    I'm trying to put the console into "raw" mode in Java. I understand this will only work on UNIX. I'm using the command stty raw If I type the command into the terminal directly, it does what it's supposed to do. In Java, I try to set the mode like this: Runtime.getRuntime().exec("stty raw"); But the terminal does not go into raw mode. I have a feeling this is because Java is just executing the command in a virtual terminal in the background or something, rather than the active terminal. Is there a way to do this?

  • Dynamic, reflective SignalHandler in Java

    - by pilcrow
    How do I install signal handling logic iff sun.misc.Signal is available? Background First generation of my code looked something like this: class MyApp { public static void main(String[] args) { ... Signal.handle(term_sig, new SignalHandler() { public void handle(Signal sig) { ... } }); ... } } I believe I understand how to reflectively test for and use signal handlers -- Class.forName("sun.misc.Signal"), reflectively call Signal.handle, and so forth. My impulse was simply to instantiate another anonymous inner class with the dynamically obtained SignalHandler class, but I think that's just wishful syntax.

  • UITableView - Loading data from internet

    - by Emil
    Hey. I have seen many apps that load data to UITableViews from the internet, and they usually load smoothly. Now it's my turn to load in that kind of data. I am getting different data at the same time, separating categories with ~ and pieces of categories with #. This works great, and I have managed to separate the data in obj-c perfectly. Everything in my app works, it's just that the loading takes a lot of time. So, I guess the real question is, how can you load in data for a tableView in the background, showing a label/UIActivityView or something while it is loading? Thank you.

  • Cleanest Way to Invoke Cross-Thread Events

    - by Nick
    I find that the .NET event model is such that I'll often be raising an event on one thread and listening for it on another thread. I was wondering what the cleanest way to marshal an event from a background thread onto my UI thread is. Based on the community suggestions, I've used this: // earlier in the code mCoolObject.CoolEvent+= new CoolObjectEventHandler(mCoolObject_CoolEvent); // then private void mCoolObject_CoolEvent(object sender, CoolObjectEventArgs args) { if (InvokeRequired) { CoolObjectEventHandler cb = new CoolObjectEventHandler( mCoolObject_CoolEvent); Invoke(cb, new object[] { sender, args }); return; } // do the dirty work of my method here }

  • How to create a splash activity , call a second activity via a button, simple data form 5 fields and 2 buttons

    - by Mike
    New to Android need help with one solid build that I can refer to and study for future projects. The first activity is a background image with a button,when clicked the it takes you to the second activity which is a form with 5 data fields and 2 buttons. One button calls an intent to take a picture within the app and one button that submits the data from the form along with the picture to URL. lastly a third activity that says complete thank you. I can make some of this but don't know how to link button or open and merge camera with the app to be sent as a package of data. I suppose I could also hook into GPS acquire location as well as the camera call?

  • How to tell iPhone NSURLConnection to abort

    - by Jahmic
    I have an app that makes moderate use of NSURLConnection. These async calls eventually finish and release properly (it looks like), but sometimes it takes some time for them to finish. So, there are times when I exit the app, (note, not just sending it the background), that some of these connections are still active. If I immediately restart the app, the app freezes on startup. (didFinishLaunchingWithOptions never seems to get called). While I'm not certain these connections are the issue, it would probably be good to terminate or cancel any remaining. Any suggestions on how to do this? Bonus points on how to debug the restart also. (I'm already saving NSLog statements to a downloadable file)

  • Using CSS to positon text after an image

    - by Charles L
    I've trying to do something that I'm sure is simple, but I can't do it. All I want to do is have an image and then some text after that image, and be able to control accurately the amount of space between the image and the text. Here's my code: http://pastebin.com/fx17XUaR I couldn't work out how to paste it in here directly. In my style sheet, wrap has these attributes: .wrap { //text-align: left; width: 1100px; height: 870px; background-color: white; color: black; padding: 10px; margin: auto; I want my text to look like this directly below the image: Username Age Location Currently, I just add loads of break tags to control where I have the text, but that's messy and there must be a better way. Thanks in advance for any help.

  • Basic QT Event handling / Threading questions ?

    - by umanga
    Greetings , I am new to QT (4.6) and have some basic questions regarding its event mechanism.I come from Swing background so I am trying to compare it with QT. 1) Does Event-processing-loop run in seperate thread? (like EventDispatch thread in Swing) ? 2) If we open several 'QMainWindow' do they run in several threads? 3) Whats the best way to run an intensive process in a seperate thread? (like SwingWorker in Swing ? ) 4) If intesive-process runs in a seperate thread ,is it possible to call UI methods like update(),repaint() from that process? thanks in advance.

  • Ripping a CD to mp3 in C# - third party component or api out there?

    - by Jonathan Williamson
    We're working on a project that requires the ripping of audio tracks from CDs to MP3s (ideally also retrieving the track information from CDDB or similar). More background information: Various music labels send us CDs of music which we then deliver to people via an online delivery system. We're looking at automating the process of converting those CDs into MP3s with full track information where possible. We want to produce a simple desktop application that allows a member of editorial staff to setup the information about the new music we receive. To streamline the process we'd like to include the ripping of the audio and retrieval of the track information.

  • iphone singleton object synchronization

    - by user127091
    I'm working on an iphone app but this is probably a general question. I have a singleton Model class and there would be scenarios where multiple NSOperations (threads) would exist and work with the singleton object. If they all call the same method in this object, do i need to have some locking mechanism? Or can this method be executed only one at a time? I do not have a computer science background but my guess is that all threads would have their CALL to the same address (this method). Also can you please suggest a good beginner programming book that discusses general programming concepts. I don't have the brains for Knuth kinda books.

  • What would you like to see in a book about Rails 3?

    - by Ryan Bigg
    Hello, I'm thinking of writing a book about Rails 3 and I have a basic idea of what I want to write about, but really what I need is that little bit of polish from the community. The book is planned to cover: A little bit of Ruby Version control using Git Testing using RSpec & Cucumber Life without Rails (Rack) Developing an application in Rails (vague, I know, sorry! Work in progress) Javascript testing using Selenium Background processing Document databases (a tentative maybe, at this stage) Monitoring an application And a little more. So, I leave this question for you: What do you want to see in a book about Rails 3, which goes from "This is Rails" to "This is how Rails scales"?

  • Linux program - reverse highlighted text

    - by Oren
    I want to develop a program that will run on the background of my Ubuntu 12.04 so when some text is selected in some textbox of any running program and some key-combination is pressed (like ctrl-F12), the text will be cut, reversed, and pasted in the same place. I know some programs that do it on windows. It is useful in some programs and web-pages that do not support right-to-left languages like arabic and hebrew - the letters are printed from left to right so the text becomes reversed. More specifically I need it in Prezi that has this kind of bug in their embedded flash editor (I thought about writing a chrome-plugin, but I don't think such plugin can manipulate the selected text inside a flash objects). Do you know if such a program exist? Where should I start reading in order to develop a program with such capabilities (manipulate selected text in other programs)? Thanks

  • How do would you use jQuery's .each() to apply the same script to each element with the same class?

    - by derekmx271
    I have a with multiple cart items listed. I have a "x-men logo" looking remove button that I want to fade-in next to the item when the customer hovers over a cart item. I had no issue getting this to work when there is only one item in the list. However, when there are multiple items in the cart, the jQuery operates funky. It still does the fade in, but only when I hover over the last item in the cart, and of course all of the "remove X" images become visible. Argh... So i searched around and think the .each() is my savior. I have been trying to get it to work, with no luck. My script just breaks when I attempt to implement it. Anyone have any pointers on this *.each() thing and how to implement it into my script?* I have tried putting a cartItem.each(function(){ around the mouseEnter/mouseLeave events (and used some $(this) selectors to make it "make sense") and that didn't do anything. Tried some other things as well with no luck... Here is the HTML (Sorry, there's a lot): <ul id="head-cart-items"> <!-- Item #1 --> <li> <!-- Item #1 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=AFE&amp;f=Air_Intakes_Magnum_FORCE_Stage-1_PRO_5R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/AFE/Intakes/Air_Intakes/Magnum_FORCE_Stage-1_PRO_5R/19029">AFE Magnum FORCE Stage-1 PRO 5R Air Intakes</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$195.00</span> <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> <!-- Item #2 --> <li> <!-- Item #2 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=Exedy&amp;f=Clutch_Kits_Carbon-R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/Exedy/Clutch/Clutch_Kits/Carbon-R/19684">Exedy Carbon-R Clutch Kits</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$2,880.00</span> <!-- Here is my other Remove-X... --> <a class="remove-x" href='/cart//7806888'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> </ul> And here is the jQuery... $(document).ready(function(){ var removeX = $(".remove-x"); var cartItem = $(".head-cart-item"); // Start with an invisible X removeX.fadeTo(0,0); // When hovering over Cart Item cartItem.mouseenter(function(){ // Fade the X to 100% removeX.fadeTo("normal",1); // On mouseout, fade it back to 0% $(this).mouseleave(function(){ removeX.fadeTo("fast",0); }); }); }); If you didn't see it, here is the "X" I am trying to fade... <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> Thanks for the help in advance.

  • latex and listings : highlighting some parts of the code

    - by Jérôme
    I'm using Latex and the listings package to display some C++ code (with syntax highlighting) inside a document. I need to highlight some parts of the code. This specific highlight has nothing to do with syntax highlighting, it's just some parts of the code I'd like to highlight so that the reader can focus on it. I wish I could make some variable name, for instance, displaying in bold, and on a yellow background. Here is something I did with MSWord I'd like to reproduce with Latex (of course, not the red and green underlining) : . I haven't found a way to do it with the listings package. Is it possible ?

  • Some input regarding Dojo (smooth css change on mouseover)

    - by Andy Walpole
    I've been playing around with Dojo over the last couple of days. The script below changes the background position of the list item when the mouse is over the link. dojo.query('a[class=main-menu-link]').forEach(function(linkTwo) { dojo.connect(linkTwo, "onmouseover", function(evt) { dojo.query('#main-menu ul li').forEach(function(linkThree) { dojo.style(linkThree, { "backgroundPosition": "right center", }); }); You can see it in action in the right hand side menu: http://www.mechanic-one.suburban-glory.com/ I'm trying to work out the best of way of giving it a smooth transition between the two states... I've been looking on the Dojo documentation page but I'm not sure what is the best way of approaching it.

  • WPF: In Expression Blend, how to change Foreground of a custom button with a Border on different states?

    - by SubmarineX
    In Expression Blend 4, I want to change the Foreground of a custom button on different states. I'm just able to change the Background and BorderBrush. Just like this: If the state is "Normal", the color of text "Button" is Black, while the state is "Pressed", the color of text "Button" is White. On Brushes Panel under Properties Panel, there're 3 properties but no Foreground property: Who can help me? I'm so perplexed. Edit I find ContentControl have a Foreground property, but ContentPresenter haven't. Wether I should use ContentControl instead of ContentPresenter?

  • Using Zend_Navigation, how do I create image-based navigation?

    - by SimpleCoder
    (I'm assuming my navigation should be in a layout script.) I have a navigation bar composed of rollover images. The image corresponding to the page that is active should be a different color, though. I do this by changing the image. My question is, where and how should I implement this using Zend_Navigation? Details: The menu itself is just a stack of divs that are floated to the left within a container. Each div has a background image. Thank you for your help,

  • jQuery Dialog theme not being applied

    - by Tim
    I'm using jquery-1.4.2.min.js and jquery-ui-1.8.1.custom.min.js. According to Firebug, both minimized scripts have been loaded. They both appear in the dropdown list on Firebug's Scripts tab. The dialog is launching, but there's no background and so the text below it shows through, and there's no "window" stuff at all, no titlebar, no X button. Just the floating/draggable text with a -close- link at the top left corner. I was under the impression from reading these pages http://jqueryui.com/demos/dialog/ http://jqueryui.com/themeroller/ that the UI theme-driven appearance would be automatically applied to the dialog when it was invoked using this barebones call: $('#dialog').dialog() I would be grateful for suggestions on how to troubleshoot this. Thanks

  • Will Emacs --batch run in cron will hang when require user input?

    - by J Spen
    I have a job in crontab that requires emacs --batch but if the file is currently open it requests (s, p, q) to (steal, quit, etc...) which is fine if this file is being edited to not run the script but I want to make sure it kills the cron running script so it's not sitting in the background taking up memory. I have the output set to go to a log file so I can see this happening but no way to tell whether the script was terminated even though asked for user input. Does cron terminate these scripts and how to check the PID to make sure?
