  • First Call to a Controller, Constant is defined, Second call, "uninitialized constant Oauth"?

    - by viatropos
    I am trying to get the OAuth gem to work with Rails 3 and I'm running into this weird problem... (independent of the gem, I think I've run into this once before) I have a controller called "OauthTestController", and a model called "ConsumerToken". The model looks like this. require 'oauth/models/consumers/token' class ConsumerToken < ActiveRecord::Base include Oauth::Models::Consumers::Token end When I go to "/oauth_test/twitter", it loads the Oauth::Models::Consumers::Token module and I'm able to connect to twitter no problem. But the second time I try it (just refresh the /oauth_test/twitter url), it gives me this error: NameError (uninitialized constant Oauth): app/models/consumer_token.rb:4 app/models/twitter_token.rb:2 app/controllers/oauth_test_controller.rb:66:in `load_consumer' Why is that? It has something to do with load paths or being in development mode maybe?

  • Splitting string on probable English word boundaries

    - by Sean
    I recently used Adobe Acrobat Pro's OCR feature to process a Japanese kanji dictionary. The overall quality of the output is generally quite a bit better than I'd hoped, but word boundaries in the English portions of the text have often been lost. For example, here's one line from my file: softening;weakening(ofthemarket)8 CHANGE [transform] oneselfINTO,takethe form of; disguise oneself I could go around and insert the missing word boundaries everywhere, but this would be adding to what is already a substantial task. I'm hoping that there might exist software which can analyze text like this, where some of the words run together, and split the text on probable word boundaries. Is there such a package? I'm using Emacs, so it'd be extra-sweet if the package in question were already an Emacs package or could be readily integrated into Emacs, so that I could simply put my cursor on a line like the above and repeatedly invoke some command that splits the line on word boundaries in decreasing order of probable correctness.

  • glibc backtrace - can't redirect output to file

    - by Jason Antman
    Hi, I'm in the process of debugging a C program (that I didn't write). I have all of the internal debugging tools (a whole bunch of printf's) enabled, and I wrote a small PHP script that uses proc_open() and just grabs both stdout and stderr, and time-coordinates them in one file. At the moment, the binary is dieing with a realloc() error that's caught by glibc, and a glibc backtrace is printed, beginning with: *** glibc detected *** /sbin/rsyslogd: realloc(): invalid next size: 0x00002ace626ac910 *** Here's the thing I don't understand: I've confirmed that the PHP script is catching both stdout and stderr from the binary's process and writing them to the correct files, but this backtrace is still printed to the console. Where is this coming from? Is there some magical output channel other than stdout and stderr? Any ideas on how I go about capturing this backtrace to a file, or sending it out with stderr? Thanks, Jason

  • IPhone Dev: Activate the view of a tabBar button

    - by Alex N Sanchez
    Hi, I have an application that has a tabBar that handles all the views. In the first view I have a login process. When that process finishes I want to go automatically to the second tabBar view without making the user to click in its respective tabBar button. All I've got until now is to highlight the button with this: myTabBar.selectedItem = [myTabBar.items objectAtIndex:1]; But I have no idea about how to bring the second view related to that button to the front, automatically. Until now the user has to press the button when it gets lighted (selected). Any idea about how to do this? Is it possible? It would be much appreciated. Thanks.

  • search & replace on 3000 row, 25 column spreadsheet

    - by Deca
    I'm attempting to clean up data in this (old) spreadsheet and need to remove things like single and double quotes, HTML tags and so on. Trouble is, it's a 3000 row file with 25 columns and every spreadsheet app I've tried (NeoOffice, MS Excel, Apple Numbers) chokes on it. Hard. Any ideas on how else I can clean this thing up for import to MySQL? Clearly I could go through each record manually, row by row, but would like to avoid that if at all possible. Likewise, I could write a PHP script to handle it on import, but don't want to put the server into a death spiral either.

  • How do quickly search through a .csv file in Python

    - by Baldur
    I'm reading a 6 million entry .csv file with Python, and I want to be able to search through this file for a particular entry. Are there any tricks to search the entire file? Should you read the whole thing into a dictionary or should you perform a search every time? I tried loading it into a dictionary but that took ages so I'm currently searching through the whole file every time which seems wasteful. Could I possibly utilize that the list is alphabetically ordered? (e.g. if the search word starts with "b" I only search from the line that includes the first word beginning with "b" to the line that includes the last word beginning with "b") I'm using import csv. (a side question: it is possible to make csv go to a specific line in the file? I want to make the program start at a random line) Edit: I already have a copy of the list as an .sql file as well, how could I implement that into Python?

  • Overflow on UILabels

    - by jkeesh
    I have a table view that I am customizing and I am adding a UILabel as a subview of the contentView, and I want the number of lines to be relatively consistent. I set the numberOfLines property to be 3 so it can't go more than that, but there are still some that overflow onto the 4th line. If it overflows, I want to add a a trailing ... How can I figure out if it overflows? I've tried truncating at different character counts of my string, but since I am using lineBreakMode = UILineBreakModeWordWrap the number of characters doesn't really predict the number of lines. Is there a way to find out the number of lines your UILabel is using?

  • NSZombieEnabled hides EXC_BAD_ACCESS error entirely

    - by David Liu
    So I have a subclass of a UIView that starts causing EXC_BAD_ACCESS errors when I go through a specific set of conditions (run on iPad instead of iPhone or simulator, first login only). It throws the exception when the UIView subclass gets deallocated, during the last line, where I have [super dealloc]. I heard about using NSZombieEnabled, so I tossed that on to see if I could get any more information about it, but now it hides the error completely! Does anyone know a bit more about this type of situation? I thought NSZombie would start spewing stuff into my console like before, but I'm hoping that the nonexistance of errors would tell me some sort of information as well.

  • Rails: Skinny Controller vs. Fat Model, or should I make my Controller Anorexic?

    - by Nick Gorbikoff
    I know similar questions have been answered before - such as: Where should logic go, where to do certain tasks, etc. But I have a more specific question - How far should I take this axiom: "keep your controller skinny, make your model fat!" Here is an example: For instance let's say I have multiple source of verification data. A good example would be a VIN number - I can verify it against, manufacturers data source, DMV's data source, also my local databases - to see what I have on record. So I have a model called Vin and vins_controller. Inside the model I have 5 methods: check_against_local_db, check_against_dmv, check_against_car_maker_1, check_against_car_maker_2, etc. In my controller keeping with the REST, in action show - I have a simple case statement which looks at the params[:source], and based on source specified - will call specific check method. Now here is the question: Should I leave the logic that governs which data source to call in controller or should I move it to model and then in controller just do something like check_vin(source, vin)? Should I make my controller anorexic?

  • UI Controls layer on top of operating system.

    - by Mason Blier
    I'm kind of curious about what layer writing a UI platform to the level of Win32 or the X Windowing System would fall in the grand scheme of an operating system. What layers below do they primarily make use of, is it heavily based on direct communication with the graphics card driver (I can't imagine going though a rendering pipeline like OpenGL for this), or is there a graphical platform as part of the operating system which extracts this out a little more. I'm also interested in the creation of shells and the like, and I"m particularly curious as to how people go about creating alternative shells for windows, what do people look for when figuring out what methods to call or what to hook into, etc? I guess I'm fairly lost at these concepts and finding it difficult to find documentation on them. I was initially excited to have taken Operating Systems in college but it was all low level resource management stuff. Thanks all, Mason

  • Did test server port change in Rails 2.3?

    - by kareem
    I upgraded rails to 2.3.2 from 2.1.1 yesterday and a bunch of my tests started failing. When I was running under 2.1.1, the test server was running on port 3000 so I had a HOST_DOMAIN variable that included the port - HOST_DOMAIN = "localhost.tst:3000". This is so my assert_redirected_to's would succeed. Now, however, it seems that the test server is running on port 80, so the port in HOST_DOMAIN is causing tests to fail. There's no specific reason I'm keeping the port in HOST_DOMAIN. I more want to know whether something in Rails 2.3 changed the port the test server runs on and where I can read more about why. I've searched a ton and can't find anything, so I'm going to my go-to place to ask development questions :) Thanks in advance.

  • Select Statement to show missing records (Easy Question)

    - by Gerhard Weiss
    I need some T-SQL that will show missing records. Here is some sample data: Emp 1 01/01/2010 02/01/2010 04/01/2010 06/01/2010 Emp 2 02/01/2010 04/01/2010 05/01/2010 etc... I need to know Emp 1 is missing 03/01/2010 05/01/2010 Emp 2 is missing 01/01/2010 03/01/2010 06/01/2010 The range to check will start with todays date and go back 6 months. In this example, lets say today's date is 06/12/2010 so the range is going to be 01/01/2010 thru 06/01/2010. The day is always going to be the 1st in the data. Thanks a bunch. :) Gerhard Weiss Secretary of Great Lakes Area .NET Users Group GANG Upcoming Meetings | GANG LinkedIn Group

  • How to add dimensions to dynamic img elements

    - by Mohammad
    I use a Json call to get a list of image addresses, then I add them individually to a div like this. <div id="container"> <img src="A.jpg" alt="" /> <img src="B.jpg" alt="" /> ... </div> Unfortunately the image dimension is not part of the Json information but I do need them for later JQuery DOM interactivity. Do any of you JQuery geniuses know of a code that would flawlessly add the width and height to the individual image elements in the container after they load? I was thinking maybe the code could wait for the images to have a width bigger than 5px then add the new width and height to the element. But I wouldn't know how to go about that and make it work stably. Thank you so much!

  • Unit testing "hybrid" WPF/Silverlight controls

    - by Alan Mendelevich
    I'm starting a new WPF/Silverlight custom control project and wanted to do unit testing on this one. However I'm a little confused about how to approach this. This control would be based on the same codebase for both WPF and Silverlight with minor forking using #ifs and partial classes to tame the differences. I guess I could write unit tests for WPF part with NUnit, MSTest, xUnit, etc. and for the Silverlight part with Silverlight Unit Test Framework but this doesn't sound very elegant to me. I'd have to either ignore testing identical code on one of the platforms and test only differing parts (which is not very trustworthy) or rewrite tests for 2 frameworks (which is annoying). Is this the right way to go? I'm wondering if there's some guidance, articles, tutorials out there on how to approach this task. Any pointers?

  • Process-wide hook using SetWindowsHookEx

    - by mfya
    I need to inject a dll into one or more external processes, from which I also want to intercept keybord events. That's why using SetWindowsHookEx with WH_KEYBOARD looks like an easy way to achieve both things in a single step. Now I really don't want to install a global hook when I'm only interested in a few selected processes, but Windows hooks seem to be either global or thread-only. My question is now how I would properly go about setting up a process-wide hook. I guess one way would be to set up the hook on the target process' main thread from my application, and then doing the same from inside my dll on DLL_PROCESS_ATTACH for all other running threads (plus on DLL_THREAD_ATTACH for threads started later). But is this really a good way? And more important, aren't there any simpler ways to setup process-wide hooks? My idea looks quite cumbersome und ugly, but I wasn't able to find any information about doing this anywhere.

  • Windows IIS test server setup

    - by chopps
    hello everyone, I picked up a new server to do some testing and need of a little help in setting up my environment at home. Here is what I would like to do: The test server will be used to test new code and configurations for a SaaS product. I would like from my laptop to enter www.acme.com and have it hit the server. The server is connected to a wireless router. I have windows server 2008 with IIS running on an an IP of 192.168.1.4. What is the best way to set this up? I want to hit the test server for www.acme.com and not go out to the internet. Do i need to mess with the LMHosts file? Thanks for the help. Im sure its easy but have never done this before.

  • Remove another user's lock obtained with sp_getapplock on SQL Server

    - by joshperry
    We have a system that uses sp_getapplock to create an exclusive mutex any time someone opens an order in the GUI. This is used to prevent multiple people from making changes to an order simultaneously. Sometimes people will open an order and go home, leaving it open. This effectively blocks anyone from being able to make changes to the order. I then get emails, calls and end up doing a kill <spid> in enterprise manager. Obviously I've gotten sick of this and want to make a quick self-service webform. The main problem I've run into is that kill requires sysadmin privileges, which I do not want to give to the user that the our website runs as. I have tried sp_releaseapplock but this doesn't let you release another user's lock (even when calling it as a sysadmin). So, finally my question; does anyone know of an alternative method to release a lock that was obtained by another user using sp_getapplock?

  • Is it worth it to learn an esoteric programming language?

    - by Thomas Owens
    Wikipedia: An esoteric programming language (sometimes shortened to esolang) is a programming language designed as a test of the boundaries of computer programming language design, as a proof of concept, or as a joke. There is usually no intention of the language being adopted for real-world programming. Such languages are often popular among hackers and hobbyists. This use of esoteric is meant to distinguish these languages from more popular programming languages. Some more popular languages may appear esoteric (in the usual sense of the word) to some, and though these could arguably be called "esoteric programming languages" too, this is not what is meant. I think it might be worth it, just to learn a new language and go through the process, although only if you don't have anything else to do (like a real project or learning a new real language). But what does the community think? Is there some value in these languages?

  • Sql Paging/Sorting - Efficent method with dynamic sort?

    - by dmose
    I'm trying to implement this style of paging: http://www.4guysfromrolla.com/webtech/042606-1.shtml CREATE PROCEDURE [dbo].[usp_PageResults_NAI] ( @startRowIndex int, @maximumRows int ) AS DECLARE @first_id int, @startRow int -- A check can be added to make sure @startRowIndex isn't > count(1) -- from employees before doing any actual work unless it is guaranteed -- the caller won't do that -- Get the first employeeID for our page of records SET ROWCOUNT @startRowIndex SELECT @first_id = employeeID FROM employees ORDER BY employeeid -- Now, set the row count to MaximumRows and get -- all records >= @first_id SET ROWCOUNT @maximumRows SELECT e.*, d.name as DepartmentName FROM employees e INNER JOIN Departments D ON e.DepartmentID = d.DepartmentID WHERE employeeid >= @first_id ORDER BY e.EmployeeID SET ROWCOUNT 0 GO This method works great, however, is it possible to use this method and have dynamic field sorting? If we change this to SELECT e.*, d.name as DepartmentName FROM employees e INNER JOIN Departments D ON e.DepartmentID = d.DepartmentID WHERE employeeid >= @first_id ORDER BY e.FirstName DESC It breaks the sorting... Is there any way to combine this method of paging with the ability to sort on different fields?

  • Dynamically assigning properties on a non data bound ASP.NET control

    - by thinknow
    For example, let's say I have a HyperLink: <asp:HyperLink runat="server" Text="Foo" NavigateUrl="foo.aspx" /> How can I set the NavigateUrl on the server side, without having to go the code-behind? This doesn't work of course: <asp:HyperLink runat="server" Text="Foo" NavigateUrl="<%= urlString %>" /> (where urlString might be a string I created earlier in the page) And this doesn't work because the HyperLink is not within a data bound control: <asp:HyperLink runat="server" Text="Foo" NavigateUrl='<%# urlString %>' /> I guess I could just use a standard anchor element: <a href="<%= urlString %>">Foo</a> But I'd rather not mix up HTML and ASP.NET controls, and it would be handy to be able to do this for other controls. Surely there must be a way?

  • Opencart not working

But when I change the physical path in the basic settings for this website in the iis manager to the sstore/upload/ directory only text shows up. No images can be found or css style sheets. So basically www. sunnybrookfs. com/ goes to my xampp page, then I can access my OpenCart by going to http://www.sunnybrookfs.com/sstore/upload/. If I want www.sunnybrookfs.com to point to my store it does not work. Any suggestions? Thank you.

    Hi, I have a website using asp.net mvc in which I need to embed a flash file in view. I am unable to set the relative path for the flash file. Given below is the code I am using: AC_FL_RunContent( 'codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0', 'width', '487', 'height', '359', 'menu', 'false', 'movie', 'images/butterfly', 'quality', 'high', 'allowscriptaccess', 'sameDomain', 'pluginspage', 'http://www.macromedia.com/go/getflashplayer' ); where I copied butterfly.swf in a directory called images. images directory resides in the views folder. If I use code behind( default.aspx default.aspx.cs) in a different solution with the same folder strucuture, browser is able to load the flash file. Could you please throw some light on the MVC folder structure issue?? Thanks a lot. Mahesh
