• Version control for subtitle creation

  - by user3635

  We make subtitles for a TV series and I plan to use a VCS for it. The structure of project directory is like this: series/ episode1/nameofepisode1.str episode2/nameofepisode2.str episode3/nameofepisode3.str ... Question: When I finish subtitle of an episode, I want to assign release tag for this episode (episode1_v1). I wanted to use git for this, but in git tag is assigned only to the whole repository. What to do, so that I can view every episode progress separately? Maybe there are some more suitable VCS for this?

• Windows 7 batch files: How to write string to text file without carriage return AND trailing space?

  - by oscilatingcretin

  I am trying to have my batch file write a string of text to a text file. At first, the command I was using was writing an extra carriage return to the end of the string, but I found this command that prevented that: echo|set /p=hello>hello.txt However, now it's putting a trailing space at the end. I need only the string I specify to be written without any extra characters. Is this possible?

• is_admin? function in rails? - undefined method Error

  - by Newbie

  Hello! At the moment, I am creating some kind of admin panel/backend for my site. I want to do the following: Only admins (a user has a user_role(integer) -- 1 = admin, 2 = moderator, 3 = user) can see and access a link for the admin panel. So I created an admin_controller. In my admin controller I created a new function called is_admin?: class AdminController < ApplicationController def admin_panel end def is_admin? current_user.user_role == 1 end end my route looks like. map.admin_panel '/admin-panel', :controller => 'admin', :action => 'admin_panel' and in my _sidebar.html.erb (partial in applicaton.html.erb) I created the link: <%= link_to "Admin Panel", :admin_panel unless is_admin? %> Now I get an error called: undefined method `is_admin?' Where is the problem? Please help me solving this problem!

• why arrayfun does NOT improve my struct array operation performance

  - by HaveF

  here is the input data: % @param Landmarks: % Landmarks should be 1*m struct. % m is the number of training set. % Landmark(i).data is a n*2 matrix old function: function Landmarks=CenterOfGravity(Landmarks) % align center of gravity for i=1 : length(Landmarks) Landmarks(i).data=Landmarks(i).data - ones(size(Landmarks(i).data,1),1)... *mean(Landmarks(i).data); end end new function which use arrayfun: function [Landmarks] = center_to_gravity(Landmarks) Landmarks = arrayfun(@(struct_data)... struct('data', struct_data.data - repmat(mean(struct_data.data), [size(struct_data.data, 1), 1]))... ,Landmarks); end %function center_to_gravity when using profiler, I find the usage of time is NOT what I expected: Function Total Time Self Time* CenterOfGravity 0.011s 0.004 s center_to_gravity 0.029s 0.001 s Can someone tell me why? BTW...I can't add "arrayfun" as a new tag for my reputation.

• Adding local users / passwords on Kerberized Linux box

  - by Brian

  Right now if I try to add a non-system user not in the university's Kerberos realm I am prompted for a Kerberos password anyway. Obviously there is no password to be entered, so I just press enter and see: passwd: Authentication token manipulation error passwd: password unchanged Typing passwd newuser has the same issue with the same message. I tried using pwconv in the hopes that only a shadow entry was needed, but it changed nothing. I want to be able to add a local user not in the realm and give them a local password without being bothered about Kerberos. I am on Ubuntu 10.04. Here are my /etc/pam.d/common-* files (the defaults that Ubuntu's pam-auth-update package generates): account # here are the per-package modules (the "Primary" block) account [success=1 new_authtok_reqd=done default=ignore] pam_unix.so # here's the fallback if no module succeeds account requisite pam_deny.so # prime the stack with a positive return value if there isn't one already; # this avoids us returning an error just because nothing sets a success code # since the modules above will each just jump around account required pam_permit.so # and here are more per-package modules (the "Additional" block) account required pam_krb5.so minimum_uid=1000 # end of pam-auth-update config auth # here are the per-package modules (the "Primary" block) auth [success=2 default=ignore] pam_krb5.so minimum_uid=1000 auth [success=1 default=ignore] pam_unix.so nullok_secure try_first_pass # here's the fallback if no module succeeds auth requisite pam_deny.so # prime the stack with a positive return value if there isn't one already; # this avoids us returning an error just because nothing sets a success code # since the modules above will each just jump around auth required pam_permit.so # and here are more per-package modules (the "Additional" block) # end of pam-auth-update config password # here are the per-package modules (the "Primary" block) password requisite pam_krb5.so minimum_uid=1000 password [success=1 default=ignore] pam_unix.so obscure use_authtok try_first_pass sha512 # here's the fallback if no module succeeds password requisite pam_deny.so # prime the stack with a positive return value if there isn't one already; # this avoids us returning an error just because nothing sets a success code # since the modules above will each just jump around password required pam_permit.so # and here are more per-package modules (the "Additional" block) # end of pam-auth-update config session # here are the per-package modules (the "Primary" block) session [default=1] pam_permit.so # here's the fallback if no module succeeds session requisite pam_deny.so # prime the stack with a positive return value if there isn't one already; # this avoids us returning an error just because nothing sets a success code # since the modules above will each just jump around session required pam_permit.so # and here are more per-package modules (the "Additional" block) session optional pam_krb5.so minimum_uid=1000 session required pam_unix.so # end of pam-auth-update config

• Given an instance of a Ruby object, how do I get its metaclass?

  - by Stanislaus Wernstrom

  Normally, I might get the metaclass for a particular instance of a Ruby object with something like this: class C def metaclass class << self; self; end end end # This is this instance's metaclass. C.new.metaclass => #<Class:#<C:0x01234567>> # Successive invocations will have different metaclasses, # since they're different instances. C.new.metaclass => #<Class:#<C:0x01233...>> C.new.metaclass => #<Class:#<C:0x01232...>> C.new.metaclass => #<Class:#<C:0x01231...>> Let's say I just want to know the metaclass of an arbitrary object instance obj of an arbitrary class, and I don't want to define a metaclass (or similar) method on the class of obj. Is there a way to do that?

  When I try centering my table & getting a caption so that it reads something like "Table 1. This is the caption." the table appears at the top of the page no matter what I do.

• Rails 3 respond_to: default format?

  - by bdorry

  I am converting a Rails 2 application to Rails 3. I currently have a controller set up like the following: class Api::RegionsController < ApplicationController respond_to :xml, :json end with and an action that looks like the following: def index @regions = Region.all respond_with @regions end The implementation is pretty straightforward, api/regions, api/regions.xml and api/regions.json all respond as you would expect. The problem is that I want api/regions by default to respond via XML. I have consumers that expect an XML response and I would hate to have them change all their URLs to include .xml unless absolutely necessary. In Rails 2 you would accomplish that by doing this: respond_to do |format| format.xml { render :xml => @region.to_xml } format.json { render :json => @region.to_json } end But in Rails 3 I cannot find a way to default it to an XML response. Any ideas?

• How do I set up my @product=Product.find(params[:id]) to have a product_url?

  - by montooner

  Trying to recreate { script/generate scaffold }, and I've gotten thru a number of Rails basics. I suspect that I need to configure default product url somewhere. But where do I do this? Setup: Have: def edit { @product=Product.find(params[:id]) } Have edit.html.erb, with an edit form posting to action = :create Have def create { ... }, with the code redirect_to(@product, ...) Getting error: undefined method `product_url' for #< ProductsController:0x56102b0 My def update: def update @product = Product.find(params[:id]) respond_to do |format| if @product.update_attributes(params[:product]) format.html { redirect_to(@product, :notice => 'Product was successfully updated.') } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end

• 1-st level routes for multiple resources in Rails

  - by Leonid Shevtsov

  I have a simple SEO task. There's a City model and a Brand model, and I have to create 1st-level URLs for both (e.g. site.com/honda and site.com/boston). What's the preferred routing/controller combination to do this in Rails? I can only think of map.connect '/:id', :controller => 'catchall', :action => 'index' class CatchallController < ApplicationController def index if City.exists?(:slug => params[:id]) @city = City.find_by_slug!(params[:id]) render 'cities/show' else @brand = Brand.find_by_slug!(params[:id]) render 'brands/show' end end end but it seems to be very un-Rails to put such logic into the controller. (Obviously I need to make sure that the slugs don't overlap in the models, that's done).

• what is a TOPIC in Struts2

  - by nacho4d

  HI, I am learning struts 2 with Tiles 2 and the word "topic" shows up very frequently... What is a topic? for example: The sx:a tag (specifically the ajax a template) and the div tag support an ajax event system, providing the ability to broadcast events to topics. You can specify the topics to listen to using a comma separated list in the listenTopics attribute. What this means is that when a topic is published, usually through the ajax a template, the URL specified in the href attribute will be re-requested. Placeholder... Refresh

• Include a Class in another model / class / lib

  - by jaycode

  I need to use function "image_path" in my lib class. I tried this (and couple of other variations): class CustomHelpers::Base include ActionView::Helpers::AssetTagHelper def self.image_url(source) abs_path = image_path(source) unless abs_path =~ /^http/ abs_path = "#{request.protocol}#{request.host_with_port}#{abs_path}" end abs_path end end But it didn't work. Am I doing it right? Another question is, how do I find the right class to include? For example if I look at this module: http://api.rubyonrails.org/classes/ActionView/Helpers/AssetTagHelper.html is there a rule of thumb how to include that module in a model / library / class / anything else ?

• variable being weirdly deleted

  - by calccrypto

  im having a weird problem with one variable: its not being recognized but its still printing. i would post my code, but it is massive. the basic idea is: # pseudocode def function(stuff): <do stuff> # These are the only 2 conditions if tag == 3: pka = <a string> if tag == 4: pka = <a string> print pka # (1) print pka # (2) <do stuff not modifying pka> print pka # (3) if pka == 'RSA': <do stuff> elif pka == 'DSA': <do stuff> my code will error at (2). however, it will print out (1), (2), and (3), all of which are the same. is there any general explanation of why this is happening? if my code is really needed, i will post it, but otherwise, i would rather not due to its size update: now the code will error at the if statement after (3), saying UnboundLocalError: local variable 'pka' referenced before assignment even though (1),(2),(3) just printed

• Fastest/One-liner way to list attr_accessors in Ruby?

  - by viatropos

  What's the shortest, one-liner way to list all methods defined with attr_accessor? I would like to make it so, if I have a class MyBaseClass, anything that extends that, I can get the attr_accessor's defined in the subclasses. Something like this: class MyBaseClass < Hash def attributes # ?? end end class SubClass < MyBaseClass attr_accessor :id, :title, :body end puts SubClass.new.attributes.inspect #=> [id, title, body] What about to display just the attr_reader and attr_writer definitions?

• Repeat over files in a File > Open dialog with Applescript

  In the below script I use an Application other than Finder to launch an "Open" browser and perform a search in it. I've got the window into the state I want, but whatever I try can't access the list of files to repeat over. If anyone can help by adding the code to repeat over that file list and log out the file path of each file it'd be a huge help.

• Regular expression from font to span (size and colour) and back (VB.NET)

  - by chapmanio

  Hi, I am looking for a regular expression that can convert my font tags (only with size and colour attributes) into span tags with the relevant inline css. This will be done in VB.NET if that helps at all. I also need a regular expression to go the other way as well. To elaborate below is an example of the conversion I am looking for: <font size="10">some text</font> To then become: <span style="font-size:10px;">some text</span> So converting the tag and putting a "px" at the end of whatever the font size is (I don't need to change/convert the font size, just stick px at the end). The regular expression needs to cope with a font tag that only has a size attribute, only a color attribute, or both: <font size="10">some text</font> <font color="#000000">some text</font> <font size="10" color="#000000">some text</font> <font color="#000000" size="10">some text</font> I also need another regular expression to do the opposite conversion. So for example: <span style="font-size:10px;">some text</span> Will become: <font size="10">some text</font> As before converting the tag but this time removing the "px", I don't need to worry about changing the font size. Again this will also need to cope with the size styling, font styling, and a combination of both: <span style="font-size:10px;">some text</span> <span style="color:#000000;">some text</span> <span style="font-size:10px; color:#000000;">some text</span> <span style="color:#000000; font-size:10px;">some text</span> I apprecitate this is a lot to ask, I am hopeless with regular expressions and need to find a way of making these conversions in my code. Thanks so much to anyone that can/is willing to help me!

• Match an element of an array to a different element in that array

  - by Anh

  I have an array containing several students. I want them to cross-grade one another randomly, i.e. each student will grade someone and will be graded by someone else (these two people may or may not be the same person). Here is my working solution. I'm sure there is a more elegant answer! def randomize(student_array) graders = student_array.dup gradees = student_array.dup result = {} graders.each do |grader| gradee = grader while gradee == grader gradee = gradees.sample end result[grader] = gradee gradees.delete_at(gradees.index(gradee)) end return result end

I know I can duplicate my code to make it work but how to dynamically create the services? Thanks!

• Why is new showat attribute required when using code generation?

  - by Patrick Karcher

  When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile: Control "ddState" is missing required attribute "showat". I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following: <asp:dropdownlist id="ddState" runat="server" showat="client" /> solves the problem. Why do I have to add this to generated code but not other times? (It's a VS-2010 webforms project, using VB, in case that makes a difference.)

• Using True and False to select items to print

  - by user1753915

  I have a workbook that contains rows of information that needs to printed to a seperate worksheet in excel. I am trying to utilize a checkbox to indicate which items need to print and which items need to be skipped. The checkbox is located in column "A" and once checked and the macro ran, I want it to pick up the data in each cell of that particular row, transfer it a seperate worksheet (form), prompt and save the worksheet to pdf, clear the form, and then return to the main worksheet to continue until all rows have been checked. However, right now, my code is only looping through the very first "TRUE" statement and not continuing to the rest. Here is the code: Private Sub CommandButton1_Click() On Error GoTo ErrHandler: Dim i As Integer For i = 1 To 10 If ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = False Then Else If ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = True Then Call PrintWO Else End If Do Until ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = 10 MsgBox "Nothing Selected to Print" Exit Do Exit Sub Loop End If Next i ErrHandler: End Sub

• C++ vector<T>::iterator operator +

  - by Tom

  Hi, Im holding an iterator that points to an element of a vector, and I would like to compare it to the next element of the vector. Here is what I have Class Point{ public: float x,y; } //Somewhere in my code I do this vector<Point> points = line.getPoints(); foo (points.begin(),points.end()); where foo is: void foo (Vector<Point>::iterator begin,Vector<Point>::iterator end) { std::Vector<Point>::iterator current = begin; for(;current!=end-1;++current) { std::Vector<Point>::iterator next = current + 1; //Compare between current and next. } } I thought that this would work, but current + 1 is not giving me the next element of the vector. I though operator+ was the way to go, but doesnt seem so. Is there a workaround on this? THanks

• use simplexml to get attributes of elements

  - by user1291894

  I am trying to parse an xml file with a soap envelope from a web service using php. I would like to use SoapClient, but I get an error back that 'page must be viewed over secure channel SSL', which I think is an issue on their end, so I gave up on that. Currently I am using curl to get a result back. Then I put it into a simplexml object like so: <?php $xml = @simplexml_load_string($result, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); $xml->registerXPathNamespace('xs', 'http://www.w3.org/2001/XMLSchema'); $output = $xml->xpath('//soap:Body'); ?> I now have this: Array ( [0] => SimpleXMLElement Object ( [GetDocumentListResponse] => SimpleXMLElement Object ( [GetDocumentListResult] => <NewDataSet> <xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"> <xs:element name="_x0023_temp_list"> <xs:complexType> <xs:attribute name="tran_datetime" type="xs:string" /> <xs:attribute name="sender" type="xs:string" /> <xs:attribute name="doc_type_num" type="xs:string" /> <xs:attribute name="doc_date" type="xs:string" /> <xs:attribute name="doc_num" type="xs:string" /> <xs:attribute name="doc_sys_no" type="xs:string" /> <xs:attribute name="is_new" type="xs:string" /> </xs:complexType> </xs:element> <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true"> <xs:complexType> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element ref="_x0023_temp_list" /> </xs:choice> </xs:complexType> </xs:element> </xs:schema> <_x0023_temp_list tran_datetime="2012-03-22T13:37:17.237" sender="webservice" doc_type_num="100" doc_date="2012-03-22T13:37:17.253" doc_num="12345" doc_sys_no="1234567" is_new="1" /> </NewDataSet> ) ) ) I am able to loop through this object and get to the part between the "NewDataSet" tags, but I can't seem to get to the individual elements. What I need is the attributes in the last tag that starts with _x0023_temp_list. I'm not sure if the tag is always going to be named that, so I will probably also have to deal with getting attributes from the tag with the xs namespace as well. I've read quite a few other posts and have tried several different methods of getting the info and so far nothing has seemed to work.

• sql query where parameters null not null

  - by Laziale

  I am trying to do a sql query and to build the where condition dynamically depending if the parameters are null or no. I have something like this: SELECT tblOrder.ProdOrder, tblOrder.Customer FROM tblOrder CASE WHEN @OrderId IS NOT NULL THEN WHERE tblOrder.OrderId = @OrderId ELSE END CASE WHEN @OrderCustomer IS NOT NULL THEN AND tblOrder.OrderCustomer = @OrderCustomer ELSE END END This doesn't work, but this is just a small prototype how to assemble the query, so if the orderid is not null include in the where clause, or if the ordercustomer is not null include in the where clause. But I see problem here, for example if the ordercustomer is not null but the orderid is null, there will be error because the where keyword is not included. Any advice how I can tackle this problem. Thanks in advance, Laziale
