• How to thoroughly clean up a ruby on rails project?

  - by hip10

  Hi, I am very new to ruby on rails. I've installed a complicated ruby on rails project via github clone and bundle install, and I was making minor changes to it until it reaches a point whereby it is not stable anymore, sass was throwing strange exceptions, so did other ruby gems. For a rails project, is there a way to clean up the project (aka, remove any "compiled or cached code") and just run again. My alternative now is to go thru github clone and bundle install again, but that means all of my modified changes have to be reapplied again. What is rails equivalent of "make clean" in Java? Is "rake clean" the answer? Do we need to run any bundle commands?

• How can I "override" deepcopy in Python?

  - by Az

  Hi there, I'd like to override __deepcopy__ for a given SQLAlchemy-mapped class such that it ignores any SQLA attributes but deepcopies everything else that's part of the class. I'm not particularly familiar with overriding any of Python's built-in objects in particular but I've got some idea as to what I want. Let's just make a very simple class User that's mapped using SQLA. class User(object): def __init__(self, user_id, name): self.user_id = user_id self.name = name I've used dir() to see, before and after mapping, what SQLAlchemy-specific attributes there are and I've found _sa_class_manager and _sa_instance_state. Provided those are the only ones how would I ignore that when defining __deepcopy__? Also, are there any attributes the SQLA injects into the mapped object? (I asked this in a previous question (as an edit a few days after I selected an answer to the main question, though) but I think I missed the train there. Apologies for that.)

• A good class structure for cleaning and using input?

  - by ciscoheat

  I want to be helpful to the users of a system, so I'll clean up the input a bit before testing if it can be used. So I have a flow like this: Input: aa12345b Clean input somehow: 12345 Test if clean input is valid Use input if valid Now I want to do this in a beautiful OO-fashion (IoC, interfaces, testable, no statics, you know). Any ideas how to organize a class structure for this? Is it good to have a Cleaner and a Parser/Validator class separately, or put them as methods in the data class itself? Thanks for any help or discussion about this, and extra thanks if the answer is in C#!

• C optimization breaks algorithm

  - by Halpo

  I am programming an algorithm that contains 4 nested for loops. The problem is at at each level a pointer is updated. The innermost loop only uses 1 of the pointers. The algorithm does a complicated count. When I include a debugging statement that logs the combination of the indexes and the results of the count I get the correct answer. When the debugging statement is omitted, the count is incorrect. The program is compiled with the -O3 option on gcc. Why would this happen?

  - by tykebikemike

  I know this has been asked to death, but I cant seem to find the answer i'm looking for...

• Is Sphinx better than LaTex in writing manuals/books?

  - by Masi

  Only a few people recommended to use Sphinx at the beginning of the year. Sphinx has developed rather fast recently. I noted today that Sage has made a change from direct editing with LaTex to Sphinx. This is evident in William Stein's answer on 2nd April about Sage's tutorial The tutorial is not a latex document anymore. It's an entirely different Sphinx document that can output pdf. It suggests me that Sphinx may be at a level such that it is suitable for me. Is Sphinx better than LaTex in writing manuals/books?

• Detect movie being played (Windows)

  - by modosansreves

  Watching a movie is quite a different user activity. User doesn't touch neither mouse nor keyboard. Yet he 'actively' uses the computer. Thus, screensaver shouldn't run, indexing should be performed with care etc. On the other side, playing video requires either using direct write to video memory, or DirectShow, or some other API. This may be the key to the answer. What is the Dead Simple Way to determine that a video is being played?

• APP CAN'T LAUNCH IN XCODE

  - by user2977180

  I'm beginning to code in xCode 5 and I'm doing a really simple app. I just began and, when I try to test my game with iOS Simulator, the main page opens, but when I click on the button to launch the game, I'm redirected to xCode and this appears: #import "AppDelegate.h" #import "AppDelegate.h" int main(int argc, char * argv[]) { @autoreleasepool { return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); } } and just next to it, this is written: Thread 1 : Signal SIGABRT I searched on internet and I just can't seem to find an answer. Could someone help me please???

• Accessing entire netflix catalog via API v1.5

  - by Stone

  Netflix recently updated their API methods for obtaining the full Netflix catalog. I'm curious if anyone has had any success accessing these new xml documents and downloading them via API v1.5 (9/2012). Previously, you could download the entire Netflix catalog via one API call (which I had working perfectly). Now, there are supposedly two calls to make: one for dvd's and one for streaming movies. I cannot make these calls return anything except for an empty array. Please don't offer an answer unless you have personally downloaded the entire catalog via these new API's. Bonus points if you can tell me how to do it in Ruby. http://developer.netflix.com/blog/read/Update_Changes_for_the_Public_API

• Why does my Eclipse crash all the time?

  - by Marcel

  Somehow stupid question, I have to admit - hope it won't cost me too many points. To make it clear: I would also be happy if you can help me find the reason for the crashes. I wouldn't expect a precise answer. However, I don't see why my Eclipse is crashing (freezing) all the time. Mostly when I save a file. For some reason, crashes seem to increase lately... I use Eclipse Helios (Version: 3.6.1) and java version "1.6.0_20" (OpenJDK Runtime Environment (IcedTea6 1.9.2) (6b20-1.9.2-0ubuntu2) OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)) on Ubuntu 10.10 (64-Bit). Thank you!

• Stop sign icon in VS2005 Express solution explorer

  - by Andy Bisson

  What does a small stop sign icon on a file in solution explorer mean? Someone asked the same question a year ago Original Question but the answer provided is of no help. The icon looks like this: Suffice to say that the sign is not one presented in the VS documentation and is a UK Stop sign (red circle with a white horizontal bar) not a US one. The project is WebKit and the build process cannot find AuthenticationCF.h even though the file is present. I presume the sign might shed some light on this. Thanks, Andy

• C/C++ usage of special CPU features

  - by b-gen-jack-o-neill

  Hi, I am curious, do new compilers use some extra features built into new CPUs such as MMX SSE,3DNow! and so? I mean, in original 8086 there was even no FPU, so compiler that old cannot even use it, but new compilers can, since FPU is part of every new CPU. So, does new compilers use new features of CPU? Or, it should be more right to ask, does new C/C++ standart library functions use new features? Thanks for answer.

• How does windows differentiate between regular exe and a .Net exe?

  - by Yogendra

  Hi All, This might be a duplicate entry. Excuse me if it is. I was asked in an interview as to how does Windows OS differentiate between regular exe and .Net exe. My reply was, when .Net exe is build, the compiler emits some information into the header. The information is PE32 or PE32+. windows verifies the header to determine if it needs to load the MSCOREE.dll which loads the CLR and executes the exe. I am not sure if my answer is correct ? Your inputs is appreciated.

• create a folder and files in c:\program files\myApp\data in windows 7

  - by ile

  I have an old c++ application that needs to be modified to work with windows 7. Problem is in creating a new folder and saving a file in that folder. This folder should be created in c:\program files\myApp\data\newFolder. This is function I use to create new folder and get errors: if(!CreateDirectory(pathSamples,NULL)) //Throw Error { DWORD errorcode = GetLastError(); LPVOID lpMsgBuf; FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, errorcode, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR)&lpMsgBuf, 0, NULL ); MessageBox(NULL, (LPCTSTR)lpMsgBuf, TEXT("Error"), MB_OK); } In XP this works, but in Windows 7 it doesn't. If I run application as administrator than the folder is created, otherwise "Access is denied" error is thrown. My question is following: Is there an option to make changes to the code so that the folder can be created in "program files" nad that files can be saved in this folder? PS I saw this thread already but it doesn't answer my question. Thanks, Ilija

• Trigger button click with JavaScript on Enter key in Text Box

  - by ziondreams

  I have one text input and one button (see below). How can I use JavaScript to trigger the button's click event when the Enter key is pressed inside the text box? There is already a different submit button on my current page, so I can't simply make the button a submit button. And, I only want the enter key to click this specific button if it is pressed from within this one text box, nothing else. <input type="text" id="txtSearch" /> <input type="button" id="btnSearch" value="Search" onclick="doSomething();" /> Update: I'd like to accept my own answer below, but since that is now allowed I will accept the next best solution.

• ASP.NET Long Process and Sending updates to Browser

  - by user204588

  Hello, I've asked this before but I was hoping for another answer and perhaps some code samples because I've been having a difficult time with this. I have an asp.net page. The user hits the "Run" button and I have code IN AN ASSEMBLY, not in the APP_CODE folder that is called and runs a long process that moves product info from a file into the database. While the user waits, I would like them to see status updates like what product the import process in on and status info. I'm assuming I'd break off into another thread and use Ajax but I have no idea how to do this. Some code samples would be very helpful, thanks.

• jquery: call functions immediately after plugin

  - by Dave

  I'm sure that there's an easy answer to this, but I can't find it. I have a table 'myTable' which I stripe using the following $("#myTable tr:even").css({ "background-color": "#FEE996" }); $("#myTable tr:odd").css({ "background-color": "#FFEFAF" }); This works fine. I am also using a table filter plugin as follows $('#myTable').tableFilter(); This plugin places a blank field at the top of each column into which the filter criteria can be typed. When the table is filtered it removes unmatched rows, which in turn messes up the striping. I would like to be able to re-invoke the lines to re-stripe the table. Something like $('#myTable').tableFilter().find("tr:even").css({ "background-color": "#FEE996" }).find("tr:even").css({ "background-color": "#FFEFAF" }); Is this possible please?

• Simple explaination of Arraylists

  - by Jeremy

  I'm new to programming and I'm looking for a simple answer to build my foundation of understanding Arrays. I've used google and searched this site. After a bit of trial and error I get how to make and reference Arrays like thing[3] gets you the fourth thing in the thing array(since 0 is the first). which lets me do something like thing[3].getStupidNumber() to get the StupidNumber of the 4th thing in the thing array. Then I get to ArrayLists which seem to have much more utility but I cant make logical sense of them like Arrays. When i search I cant find this or word this correctly and thus far everything else I've learned clicked easily. so say I make an ArrayList thing with 5 things in it. how do i get to the .getStupidNumber() method inside the fourth thing, if possible? I think if I learn this I can learn the rest on my own. Thanks!

• SQL Find duplicate sets

  - by Aheho

  given this Schema: table tblSET SetID int PK SetName nvarchar(100) Table tblSetItem SetID int PK ItemID int PK tblSetItem.SetID is a FK into the tblSet Table. Some data: tblSet SetID SetName 1 Red 2 Blue 3 Maroon 4 Yellow 5 Sky tblSetItem SetID ItemID 1 100 1 101 2 100 2 108 2 109 3 100 3 101 4 101 4 108 4 109 4 110 5 100 5 108 5 109 I'd like a way to identify which sets contain the same items. In the example above Red and Maroon contain the same items (100,101) and Blue and Sky contain the same values (100,108,109) Is there a sql query which would provide this answer?

• How do I create a point system in a Rails app that assigns points to users and non-authenticated-use

  - by codyvbrown

  I'm building a question and answer application on top of twitter and I'm hitting some snags because I'm inevitably dealing with two classes of users: authenticated and non-authenticated. The site enable users to give points to other users, who may or may not be authenticated, and I want to create a site-wide point system where the application stores and displays this information on their profile. I want to save this point data to the user because that would be faster and more efficient but non-authenticated users aren't in our system, we only have the twitter handle. So instead we display the points in our system like this: @points = point.all( :select => "tag, count(*) AS count", # Return tag and count :group => 'tag', # Group by the tag :order => "2 desc", :conditions => {:twitter_handle => params[:username]}) Is there a better way to do this? Is there a better way to associate data with non-authenticated users?

• [SEO] sitemap.xml What is the precision of the priority field?

  - by Christoph

  Unfortunately the specification does not tell anything about precision. The xml scheme definition states that it is of the type xsd:decimal: <xsd:restriction base="xsd:decimal"> <xsd:minInclusive value="0.0"/> <xsd:maxInclusive value="1.0"/> </xsd:restriction> I have a sitemap generator that uses up to 10 positions after decimal point. Where often only the last few positions differ. These numbers are perfectly right according to the xsd, but yet i found some pages(3,4) that state that only 0.0, 0.1, 0.2, .., 1.0 are valid values. How will the search engines react to such a sitemap? Will some just round the value? I know that it is unlikely that someone can provide an answer to that question, unless he works for that search engine, but i think experiences will also do.

• Division inaccurate in Javascript?

  - by Nate

  If I perform the following operation in Javascript: 0.06120*400 The result is 24.48. However, if I do this: 24.48/400 The result is: 0.061200000000000004 JSFiddle: http://jsfiddle.net/zcDH7/ So it appears that Javascript rounds things differently when doing division and multiplication? Using my calculator, the operation 24.48/400 results in the correct answer of 0.0612. How should I deal with Javascript's inaccurate division? I can't simply round the number off, because I will be dealing with numbers of varying precision. Thanks for your advice.
