How can i make a callback to accordion after form validation, to show errors

- by Esger

I have a very long form, which is divided into fieldsets which in turn are being shown or hidden, using the harmonica from jQuery UI. I am using form validation from jQuery as well, all newest versions. After submission and validation the user is redirected to the first erroneous field by $('myForm').validate(); But the containing harmonica fieldset has to be showed/opened with $('myForm').accordion('activate', index); as well, in order to show the field to the user. So how can I open the appropriate accordion fieldset after the form has been tried to submit? Is there a way to do it in a callback function after $('myForm').validate();

How can I use git to stage only one line in a file for commit, all from a script?

- by Sandy

I'm writing a simple pre-commit git hook that updates the year in copyright headers for files that are staged for commit. After modifying the line with the copyright, I would like the hook to stage that line so that it is part of the commit. It can't just git add the whole file, because there may be other pre-existing changes in there that shouldn't be staged. I don't see any options in the git add manual the let you stage specific lines. I figure I could git stash save --keep-index, apply my change, git add the file, and then git stash pop, but that seems rather crude. Any better approaches?

How do stream rows from a MSSQL table into a .NET app, in 10000 row chunks?

- by Gravitas

I have a table with 300 million rows in Microsoft SQL Server 2008 R2. There is a clustered index on the date column [DataDate] which means that the entire table is ordered by the date column. How do I stream out the data from this table, into my .NET application, in 10000 row chunks? Environment: Using C#. Have to be able to pause the data stream at any point, to allow the client to process the rows. Unfortunately, cannot use a select * from as this will select the entire table (its 50GB - it won't fit into memory).

How can i test my DB speed? (Learning)

- by acidzombie24

I have design a database. Theres no columns with indexing, nor any code for optimizing. I am positive i should index certain columns since i search them a lot. My question is HOW do i test if any part of my database will be slow? ATM I am using sqlite and i will be switching to either MS Sql or MySql based on my host provider. Will creating 100,000 records in each table be enough? Or will that always be fast in sqlite and i need to do 1mil? Do i need 10mil before a database will become slow? Also how do i time it? I am using C# so should i use StopWatch or is there a ADO.NET/Sqlite function i should use?

"Introduction to Computer Science and Programming" for a beginner.

- by Richard

Hi everyone! Im new here and also new to developing software and programming, and with new I mean 0 experience or schooling for it. As Im currently studying medicine via internet and I use a computer on an average of about 8-9 hours a day, this has lead me to get very interested in programming. I got a link from a fellow Redditor and I got some questions before I dive into this project. http://ocw.mit.edu/OcwWeb/Electrical-Engineering-and-Computer-Science/6-00Fall-2008/CourseHome/index.htm Is this too much/hard for a beginner? Is Python™ programming language the way to go or would I be better off learning some other kind of language to begin with? What other ways of learning basic programming by myself is there? Are there any better ways for a complete beginner to start off? Thank you for your time!

Rails + RSpec problem

- by FancyDancy

I have just installed Rspec and Rspec-rails. When i try to run the test, it says: rake aborted! Command /opt/local/bin/ruby -I"lib" "/opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/bin/spec" "spec/controllers/free_controller_spec.rb" --options "/Volumes/Trash/dev/app/trunk/spec/spec.opts" failed Full log here: http://pastie.org/939211 However, my second "test" application with sqlite works with it. I think the problem is in my DB. My ruby version is 1.8.7, i use mysql as database. My files: specs/spec_helper.rb config/environment.rb config/environments/test.rb List of my gems My test is just: require 'spec_helper' describe FreeController do it "should respond with success" do get 'index' response.should be_success end end I really can't understand the error, so i don't know how to fix it.. Additional question: should i use a fixtures and ActiveRecord, if i going to use Machinist for creating test data? What should i do to disable them?

How can I delete a specific element in priority queue?

Can somebody teach how to implement...thanks!

100+ tables to joined

- by deian

Hi guys, I was wondering if anyone ever had a change to measure how a would 100 joined tables perform? Each table would have an ID column with primary index and all table are 1:1 related. It is a common problem within many data entry applications where we need to collect 1000+ data points. One solution would be to have one big table with 1000+ columns and the alternative would be to split them into multiple tables and join them when it is necessary. So perhaps more real question would be how 30 tables (30 columns each) would behave with multitable join. 500K-1M rows should be the expected size of the tables. Cheers

Remove items from one list in another

- by coffeeaddict

I'm trying to figure out how to traverse a generic list of items that I want to remove from another list of items. So lest say I have this as a hypothetical example List<car> list1 = GetTheList(); List<car> list2 = GetSomeOtherList(); I want to traverse list1 with a foreach and remove each item in List1 in List2. I'm not quite sure how to go about that as foreach is not index based.

.htaccess wildcard problem

- by niggles

I've come across a problem with an .htaccess rule I can't sort out. It works on my MAMP stack and it works on 3 other servers, but it won't work on a particular server and keeps giving me a "500 error with an additional 302 error". It's the wildcard that's throwing it and from Google research it says it may be because of an infinite loop, but it works on other servers just fine. The site in question is being developed in a sub-directory, but then again, so have the other sites: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^$ public/ [L] RewriteRule (.*) public/$1 [L] /public has it's own .htaccess file that is: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?url=$1 [PT,L] Any suggestions as mod_rewrite's not my specialty and I can't seem to fix this.2

How to convert an arbitrary object to String with EL? (calling toString())

- by hstoerr

Is there any way to call toString() on an object with the EL? (I need the String representation of an enum as index in a map in a JSP EL expression.) I hoped something like ${''+object} would work like in java, but EL isn't that nice, and there does not seem to be any function that does it. Clarification: I have a variable somemap that maps Strings to Strings, and I have a variable someenum that is an enumeration. I'd like to do something like ${somemap[someenum.toString()]}. (Of course .toString() does not work, but what does?)

jquery-ui - position of a list item when starting drag and drop?

- by user246114

Hi, I am using the jquery-ui library. I have two sortables. I want to know the index of the dragged source item. I have something like this: $(function() { $("#sortable1, #sortable2").sortable({ connectWith: '.connectedSortable' }).disableSelection(); $("#sortable1").sortable({ start: function(event, ui) { alert(ui.position); } }); }); if I'm reading the docs correctly, then ui.position should be what I want?: ui.position - current position of the helper but when I jsut try printing it: alert(ui.position) it seems to be empty. I am doing all of this in an attempt to emulate cloning. docs: http://jqueryui.com/demos/sortable/#event-activate Thanks

Facebook Open Graph - Grab how many times a page has been liked?

- by DoMx

I have a site that allows users to create a saying and then users "like" those sayings on Facebook. http://www.likeylikey.net/ I got a friend to throw up this simple code in less than 2 hours so it's basic. He knows little to nothing regarding the Open Graph API. Basically, I want to know how I can programmatically store how many times a page has been liked so I can list a "Top 10, most liked pages" list. Right now the index shows a list of all created pages and now I just wish to show the 10 most liked but I need a way of pulling that information from Facebook. Is this possible?

A good way to look back arbitrary number of items in the Array.Fold in F#

- by tk

In the folder function of the Array.Fold operation, i want to look back arbitrary number of items. The only way i can figure out is like this. let aFolder (dataArray, curIdx, result) (dataItem) = let N = numItemsToLookBack(result, dataItem) let recentNitems = dataArray.[curIdx - n .. curIdx - 1] let result = aCalc(result, dataItem, recentNitems ) dataArray, curIdx + 1, result myDataArray | Array.fold aFolder (myDataArray, 0, initResult) As you can see, I passed the whole dataArray and index to the folder function to get the "recentNitems". But this way allows the folder function to access not only preceding data, but also the following data. Is there a better (or more functional) way?

efficiently compare two BitArrays of the same length

- by BobTurbo

How would I do this? I am trying to count when both arrays have the same value of TRUE/1 at the same index. As you can see, my code has multiple bitarrays and is looping through each one and comparing them with a comparisonArray with another loop. It doesn't seem to be very efficient and I need it to be. foreach (bitArrayTuple in bitarryList) { for (int i = 0; i < arrayLength; i++) if (bArrayTuple.Item2[i] && comparisonArray[i]) bitArrayTuple.Item1++; } where Item1 is the count and Item2 is a bitarray.

Is it possible to resolve domain names to an IP address with PHP?

- by Rob

Well, very simple question. So that's good news for you, I guess. More thorough explanation: I have a PHP script allowing me to add urls to a database. I want the script to resolve the url to an IP address as well, to store that, too. However, some of the URLs are like this: http://111.111.111.111/~example/index.php So it also needs to work with that. I'm not SURE that this is possible, but it only makes sense it would be. So: Is it possible, and if so, how?

Rails routes looking for show action

- by user1334345

I am pretty new to rails and basically I want to make a user registration form. I am currently using rails 3.2.3 Basically I want to make basic routes like user/register on top of basic REST route for user. Here are my routes.rb resources :user do collection do get 'register' end end And here are my rake routes: register_user_index GET /user/register(.:format) user#register user_index GET /user(.:format) user#index POST /user(.:format) user#create new_user GET /user/new(.:format) user#new edit_user GET /user/:id/edit(.:format) user#edit user GET /user/:id(.:format) user#show PUT /user/:id(.:format) user#update DELETE /user/:id(.:format) user#destroy From my understanding, since register user is on top of show, it should match with register first before going to show. However, when I try to do localhost:3000/user/register, it gives me this error: No route matches {:action="show", :controller="user"} Can somebody help me with this? Thanks!!

Indexing a method return (depending on Internationalization)

- by Hedde

Consider a django model with an IntegerField with some choices, e.g. COLORS = ( (0, _(u"Blue"), (1, _(u"Red"), (2, _(u"Yellow"), ) class Foo(models.Model): # ...other fields... color = models.PositiveIntegerField(choices=COLOR, verbose_name=_(u"color")) My current (haystack) index: class FooIndex(SearchIndex): text = CharField(document=True, use_template=True) color = CharField(model_attr='color') def prepare_color(self, obj): return obj.get_color_display() site.register(Product, ProductIndex) This obviously only works for keyword "yellow", but not for any (available) translations. Question: What's would be a good way to solve this problem? (indexing method returns based on the active language) What I have tried: I created a function that runs a loop over every available language (from settings) appending any translation to a list, evaluating this against the query, pre search. If any colors are matched it converts them backwards into their numeric representation to evaluate against obj.color, but this feels wrong.

JavaApplicationStub with CFBundleDocumentTypes

- by mystro

I'm trying to use CFBundleDocumentTypes to associate a custom file extension with my application. As far as I can tell, this seems to "work" -- my application launches when I double click the file. However, no callback is registered through the ApplicationListener events I setup in java. I used the code listed in http://stackoverflow.com/questions/1460193/set-default-file-association-mac-os-x-java-package-maker-installer to do the file association, and the file association itself appears fine, but it seems as if it is the application stub trying to launch the file, and thus fails. I added the Apple ApplicatinListener code to my java application at (similar to http://developer.apple.com/mac/library/documentation/Java/Reference/1.5.0/appledoc/api/index.html?com/apple/eawt/Application.html) but it doesn't seem like my application ever gets a call back. the code is similar to Application.getApplicatin().addApplicationListener( new ApplicationAdapter() { public void handleOpenFile(ApplicationEvent evt) { //some logging message here that I never get} }); Any help would be appreciated

What is a valid and reasonable alternative to a massive storage approach?

- by Backo

I am using Ruby on Rails 3.2.2 and MySQL. After my previous question on "how to handle massive storage of records in database for user authorization purposes", since related answers (on how to solve the issue or how to accomplish to that I am looking for) aren't sufficiently detailed or require to much resources (at least for me), I would like to know what are valid and reasonable alternatives to that approach. In few words, this question could be phrase as: how to handle "complex" (at level of SQL querying) user authorizations when you have to fetch "authorized" records? That is, for example, how to retrieve records when you would use code like the following (the following code would be used mostly in index controller actions): Article.readable_by_user(@current_user) # => Returns all articles readable by the current user.

Is it faster to count down than it is to count up?

- by Bob

Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?
