    - by jay

  • how to detect an escape sequence in a string

    - by mix
    Given a string named line whose raw version has this value: \rRAWSTRING how can I detect if it has the escape character \r? What I've tried is: if repr(line).startswith('\r'): blah... but it doesn't catch it. I also tried find, such as: if repr(line).find('\r') != -1: blah doesn't work either. What am I missing? thx! EDIT: thanks for all the replies and the corrections re terminolgy and sorry for the confusion. OK, if i do this print repr(line) then what it prints is: '\rSET ENABLE ACK\n' (including the single quotes). i have tried all the suggestions, including: line.startswith(r'\r') line.startswith('\\r') each of which returns False. also tried: line.find(r'\r') line.find('\\r') each of which returns -1

  • Rails - How do i update a records value in a join model ?

    - by ChrisWesAllen
    I have a join model in a HABTM relationship with a through association (details below). I 'm trying to find a record....find the value of that records attribute...change the value and update the record but am having a hard time doing it. The model setup is this User.rb has_many :choices has_many :interests, :through => :choices Interest.rb has_many :choices has_many :users, :through => :choices Choice.rb belongs_to :user belongs_to :interest and Choice has the user_id, interest_id, score as fields. And I find the ?object? like so @choice = Choice.where(:user_id => @user.id, :interest_id => interest.id) So the model Choice has an attribute called :score. How do I find the value of the score column....and +1/-1 it and then resave? I tried @choice.score = @choice.score + 1 @choice.update_attributes(params[:choice]) flash[:notice] = "Successfully updated choices value." but I get "undefined method score"......What did i miss?

  • Pruning data for better viewing on loglog graph - Matlab

    - by Geodesic
    Hi Guys, just wondering if anyone has any ideas about an issue I'm having. I have a fair amount of data that needs to be displayed on one graph. Two theoretical lines that are bold and solid are displayed on top, then 10 experimental data sets that converge to these lines are graphed, each using a different identifier (eg the + or o or a square etc). These graphs are on a log scale that goes up to 1e6. The first few decades of the graph (< 1e3) look fine, but as all the datasets converge ( 1e3) it's really difficult to see what data is what. There's over 1000 data points points per decade which I can prune linearly to an extent, but if I do this too much the lower end of the graph will suffer in resolution. What I'd like to do is prune logarithmically, strongest at the high end, working back to 0. My question is: how can I get a logarithmically scaled index vector rather than a linear one? My initial assumption was that as my data is lenear I could just use a linear index to prune, which lead to something like this (but for all decades): //%grab indicies per decade ind12 = find(y >= 1e1 & y <= 1e2); indlow = find(y < 1e2); indhigh = find(y > 1e4); ind23 = find(y >+ 1e2 & y <= 1e3); ind34 = find(y >+ 1e3 & y <= 1e4); //%We want ind12 indexes in this decade, find spacing tot23 = round(length(ind23)/length(ind12)); tot34 = round(length(ind34)/length(ind12)); //%grab ones to keep ind23keep = ind23(1):tot23:ind23(end); ind34keep = ind34(1):tot34:ind34(end); indnew = [indlow' ind23keep ind34keep indhigh']; loglog(x(indnew), y(indnew)); But this causes the prune to behave in a jumpy fashion obviously. Each decade has the number of points that I'd like, but as it's a linear distribution, the points tend to be clumped at the high end of the decade on the log scale. Any ideas on how I can do this?

  • Finding specific words in a file (Python language)

    - by Caroline Yi
    I have to write a program in python where the user is given a menu with four different "word games". There is a file called dictionary.txt and one of the games requires the user to input a) the number of letters in a word and b) a letter to exclude from the words being searched in the dictionary (dictionary.txt has the whole dictionary). Then the program prints the words that follow the user's requirements. My question is how on earth do I open the file and search for words with a certain length in that file. I only have a basic code which only asks the user for inputs. I'm am very new at this please help :( this is what I have up to the first option. The others are fine and I know how to break the loop but this specific one is really giving me trouble. I have tried everything and I just keep getting errors. Honestly, I only took this class because someone said it would be fun. It is, but recently I've really been falling behind and I have no idea what to do now. This is an intro level course so please be nice I've never done this before until now :( print print "Choose Which Game You Want to Play" print "a) Find words with only one vowel and excluding a specific letter." print "b) Find words containing all but one of a set of letters." print "c) Find words containing a specific character string." print "d) Find words containing state abbreviations." print "e) Find US state capitals that start with months." print "q) Quit." print choice = raw_input("Enter a choice: ") choice = choice.lower() print choice while choice != "q": if choice == "a": #wordlen = word length user is looking for.s wordlen = raw_input("Please enter the word length you are looking for: ") wordlen = int(wordlen) print wordlen #letterex = letter user wishes to exclude. letterex = raw_input("Please enter the letter you'd like to exclude: ") letterex = letterex.lower() print letterex

  • HTML5: HTML VS XHTML spec question regarding comments

    - by NoozNooz42
    In the W3C working draft for HTML5 here's a line I find confusing: http://www.w3.org/TR/html5/introduction.html#html-vs-xhtml Comments that contain the string "--" can be represented in the DOM but not in the HTML syntax or in XML. I can interpret this in two different ways: Comments that contain the string "--" can be represented in XML and in the DOM but not in the HTML syntax Comments that contain the string"--" can be represented in the DOM but neither in the HTML syntax nor in XML. I really find the original formulation highly confusing. Which one does it mean and is it even correct english? Who should I contact if I want to point out that I find such a wording highly confusing and that hence there's a high probability that other non-native english speaker would find this kind of formulation highly confusing too?

  • No route matches when trying to edit

    - by mmichael
    Here's the scoop: I've created a test app that allows users to create ideas and then add "bubbles" to these ideas. Currently, a bubble is just text. I've successfully linked bubbles to ideas. Furthermore, when a user goes to view an idea it lists all of the bubbles attached to that idea. The user can even delete the bubble for any given idea. My problem lies in editing bubbles. When a user views an idea, he sees the idea's content as well as any bubbles for that idea. As a result, I've set all my bubble controls (editing and deleting) inside the ideas "show" view. My code for editing a bubble for an idea is <%= link_to 'Edit Bubble', edit_idea_bubble_path %>. I ran rake routes to find the correct path for editing bubbles and that is what was listed. Here's my error: No route matches {:action=>"edit", :controller=>"bubbles"} In my bubbles controller I have: def edit @idea = Idea.find(params[:idea_id]) @bubble = @idea.bubbles.find(params[:id]) end def update @idea = Idea.find(params[:idea_id]) @bubble = @idea.bubbles.find(params[:id]) respond_to do |format| if @bubble.update_attributes(params[:bubble]) format.html { redirect_to(@bubble, :notice => 'Bubble was successfully updated.') } format.xml { head :ok } else format.html { render :action => "Edit" } format.xml { render :xml => @bubble.errors, :status => :unprocessable_entity } end end end To go a step further, I have the following in my routes.rb file resources :ideas do resources :bubbles end So far everything seems to function except when I try to edit a bubble. I'd love some guidance. Thanks!

    Hi I just noticed that if you creating a new view on jEdit, when you editing the new one, it affected the text on the original window's text as well, how could I create a New view that allow the user to duplicate data for the current shown view only and not effecting the old ones? I try to find solutions on the source code, then I find seems there are setting that related to this: http://www.jedit.org/users-guide/buffersets.html but I didn't find the selection mentioned on my setting.

My thoughts were learning Scheme, making a working Zelda-like game(the original), find some open source project to help with.

  • Make xargs execute the command once for each line of input

    - by Readonly
    How can I make xargs execute the command exactly once for each line of input given? It's default behavior is to chunk the lines and execute the command once, passing multiple lines to each instance. From http://en.wikipedia.org/wiki/Xargs: find /path -type f -print0 | xargs -0 rm In this example, find feeds the input of xargs with a long list of file names. xargs then splits this list into sublists and calls rm once for every sublist. This is more efficient than this functionally equivalent version: find /path -type f -exec rm '{}' \; I know that find has the "exec" flag. I am just quoting an illustrative example from another resource.

  • intersection of three sets in python?

I know there's a much simpler and better way to do this, but I can't find one...

  • problem when cloning jQuery UI datepicker

    - by h3
    I have a div in which there is a datepicker. I use something like this to clone it: mydiv = $('#someDiv'); // works fine so far mydiv.find('input.datefield').datepicker(); // clone without the events and insert newDiv = myDiv.clone(false).insertAfter(myDiv); // datepicker won't re-init if this class is present newDiv.find('.hadDatepicker').removeClass('hadDatepicker'); // reinitialize datepicker newDiv.find('input.datefield').datepicker(); This is a stripped down version of my code. It works and the calendar shows up as expected where it is expected .. but when a date is clicked, the previous datepicker's value gets updated.. (the one from which it was cloned). I've tried to destroy the (inexisting) instance before like this: newDiv.find('input.datefield').datepicker('destroy').datepicker(); No luck .. I've checked how it keeps track of instances and manually cleared the data like this: newDiv.find('input.datefield').data('datepicker', false).datepicker('destroy').datepicker(); Still no luck. What I don't understand is that only the date selection behavior is buggy, everything else works as expected. I really don't know what else to check now ..

  • Perl: Unsuccessful stat on filename containing newline. What?

    Hello, I am getting an error I do not understand. I am using File:find to recurse a fylesystem on windows using Activestate Perl 5.8.8 and trying to stat $File::Find::name; so I am not stat-ing a filename got from a text file scanning requiring chomp-ing or newline removing. I was unable to get file modification time, the m in: my ($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,$blocks) = stat($File::Find::name); so trying a -s $File::Find::name give me the error: "Unsuccessful stat on filename containing newline" A typical file name found is F01-01-10 Num 0-00000.pdf but I get the same error even renaming in E02.pdf Some ideas about a possible reason for this error?

  • Help me understand Rails eager loading

    - by aaronrussell
    I'm a little confused as to the mechanics of eager loading in active record. Lets say a Book model has many Pages and I fetch a book using this query: @book = Book.find book_id, :include => :pages Now this where I'm confused. My understanding is that @book.pages is already loaded and won't execute another query. But suppose I want to find a specific page, what would I do? @book.pages.find page_id # OR... @book.pages.to_ary.find{|p| p.id == page_id} Am I right in thinking that the first example will execute another query, and therefore making the eager loading pointless, or is active record clever enough to know that it doesn't need to do another query? Also, my second question, is there an argument that in some cases eager loading is more intensive on the database and sometimes multiple small queries will be more efficient that a single large query? Thanks for your thoughts.

  • Problems with rails and saving to the database.

    - by Grantismo
    I've been having some difficulty in understanding the source of a problem. Below is a listing of the model classes. Essentially the goal is to have the ability to add sentences to the end of the story, or to add stories to an existing sentence_block. Right now, I'm only attempting to allow users to add sentences, and automatically create a new sentence_block for the new sentence. class Story < ActiveRecord::Base has_many :sentence_blocks, :dependent => :destroy has_many :sentences, :through => :sentence_blocks accepts_nested_attributes_for :sentence_blocks end class SentenceBlock < ActiveRecord::Base belongs_to :story has_many :sentences, :dependent => :destroy end class Sentence < ActiveRecord::Base belongs_to :sentence_block def story @sentence_block = SentenceBlock.find(self.sentence_block_id) Story.find(@sentence_block.story_id) end end The problem is occurring when using the show method of the Story. The Story method is as follows, and the associated show method for a sentence is also included. Sentence.show def show @sentence = Sentence.find(params[:id]) respond_to do |format| format.html {redirect_to(@sentence.story)} format.xml { render :xml => @sentence } end end Story.show def show @story = Story.find(params[:id]) @sentence_block = @story.sentence_blocks.build @new_sentence = @sentence_block.sentences.build(params[:sentence]) respond_to do |format| if @new_sentence.content != nil and @new_sentence.sentence_block_id != nil and @sentence_block.save and @new_sentence.save flash[:notice] = 'Sentence was successfully added.' format.html # new.html.erb format.xml { render :xml => @story } else @sentence_block.destroy format.html format.xml { render :xml => @story } end end end I'm getting a "couldn't find Sentence_block without and id" error. So I'm assuming that for some reason the sentence_block isn't getting saved to the database. Can anyone help me with my understanding of the behavior and why I'm getting the error? I'm trying to ensure that every time the view depicts show for a story, an unnecessary sentence_block and sentence isn't created, unless someone submits the form, I'm not really sure how to accomplish this. Any help would be appreciated.
