• sortable list using jquery ui not passing updated list order

  I am following the sortable lists railscast and got everything working except when I sort, the same (original) order gets passed to the update method each time, so it doesn't update the true order.

• VirtualBox Shared Folder encoding issue

  - by Somebody

  I'm using Ubuntu in Virtualbox and have a shared folder mounted to Virtualbox which i'm accessing inside Ubuntu. The problem is, that when i'm editing and saving some files from shared folder in Windows it's getting some strange symbols at the end of edited file. There must be some encoding issues. Doesn't Virtualbox automatically converts files to Unix standards? To fix that, i have to re-mount shared folder inside Ubuntu each time i'm editing some file. Any solution to avoid re-mounting each time I edit? I'm mounting like that: mount -t vboxsf SVN /opt/htdocs/ Thanks.

• Windows 7 treating my third monitor as an extension to my second rather than detecting it as a stand alone

  - by user331837

  I am trying to attach a third monitor to my PC, however I am coming across a rather strange issue. Windows screen resolution is still only showing that I have two monitors connected, but the second has been extended over both the second and third monitors. Basically, it shows as the main display being a normal size, and the secondary as being twice as long as normal. I have my main connected via a the display port, and the second and third are using two of the three mini HDMI ports my video card provides. How do I get windows to accept my third monitor the same as it does my second?

• Handle edittexts onKeyListener ?

  - by hungson175

  Hi everyone, I am creating login screen with 2 editTexts: etUsername and etPassword. On the etUsername, user should input the username and press Enter to go to the edit text etPassword, then he inputs the password, press Enter to login. Here are my current codes: etUsername.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_ENTER)) { etPassword.requestFocus(); return true; } else return false; } }); etPassword.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_ENTER)) { loginToServer(); return true; } else return false; } }); But when I input the username, and then press Enter – the program tries to log in to the server. In the debug mode, I saw that when I pressed Enter once (on the etUsername) then first: etUsername.onKey() is called and then etPassword.onKey() is also called ! Can anyone please tell me, how to implement what I want ? Thank you very much, Son

• Magento - save quote_address on cart addAction using observer

  - by Byron

  I am writing a custom Magento module that gives rate quotes (based on an external API) on the product page. After I get the response on the product page, it adds some of the info from the response into the product view's form. The goal is to save the address (as well as some other things, but those can be in the session for now). The address needs to be saved to the quote, so that the checkout (onestepcheckout, free version) will automatically fill those values in (city, state, zip, country, shipping method [of which there are 3]) and load the rate quote via ajax (which it's already doing). I have gone about this by using an Observer, and watching for the cart events. I fill in the address and save it. When I end up on the cart page or checkout page ~4/5 times the data is lost, and the sql table shows that the quote_address is getting save with no address info, even though there is an explicit save. The observer method's I've used are: checkout_cart_update_item_complete checkout_cart_product_add_after The code saving is: (I've tried this with the address, quote and cart all not calling save() with the same results, as well as not calling setQuote() $quote->getShippingAddress() ->setCountryId($params['estimate_to_country']) ->setCity($params['estimate_to_city']) ->setPostcode($params['estimate_to_zip_code']) ->setRegionId($params['estimate_to_state_code']) ->setRegion($params['estimate_to_state']) ->setCollectShippingRates(true) ->setShippingMethod($params['carrier_method']) ->setQuote($quote) ->save(); $quote->getBillingAddress() ->setCountryId($params['estimate_to_country']) ->setCity($params['estimate_to_city']) ->setPostcode($params['estimate_to_zip_code']) ->setRegionId($params['estimate_to_state_code']) ->setRegion($params['estimate_to_state']) ->setCollectShippingRates(true) ->setShippingMethod($params['carrier_method']) ->setQuote($quote) ->save(); $quote->save(); $cart->save(); I imagine there's a good chance this is not the best place to save this info, but I am not quite sure. I was wondering if there is a good place to do this without overriding a whole controller to save the address on the add to cart action. Thanks so much, let me know if I need to clarify

• Weird noise coming out on Windows 7 when harddisk activity at peak?

  - by Curious Apprentice

  I'm having a very strange problem. I'm hearing a "choooooooooo kkkrrr" sound (Its not like the normal sound speakers make when powered on) all the time. When there is more Hard Disk r/w activity the sound increases and as HDD r/w activity slows down so the sound. I have two other OS installed on my system. I have tested, it only happens when I'm on Windows 7. I have no clue what the hell is happening !? Any help would be greatly appreciated. Here's the sample of noise: http://www.ziddu.com/download/20852917/noise.mp3.html

• Mysql loses its root password

  - by RubyDev

  I am having a strange problem, my mysql loses/resets the root password automatically. By which I mean that it resets it to none. It has happened twice this month. I am worried that it can be a security issue as data is open waiting only for someone trying no password! Here is the version: mysql --version mysql Ver 14.14 Distrib 5.1.56, for redhat-linux-gnu (i386) using readline 5.1 Any help would be appreciated. Update: Output of select user, host, password from mysql.user; how it looks after the password got reset | root | localhost | | root | 127.0.0.1 | | | localhost | | | admin | localhost | ################################# | (I have removed the actual output with #) So all the passwords are blank, except for for another user named 'admin'

• Word 2010 doc skips pages

  - by Sarah

  A Word document with 9 pages, 3 section brakes next page (no odd and even breaks used) and inserted page numbers shows the correct sequence of pages when moving thru the document. When I change the page numbers in section 2 to start from 1 (Section 1 is only one page numbered with a roman numeral.) Then two strange things happen: The sequence in the status bar goes from 1 to 3. Page 2 disappeared (no text is missing) and my total number of pages reads 10 when i actually only have 9. The first page has a table of contents. Page 2 is listed, but when I press ctrl + click the shortcut it goes to page 4?

• Saving a Record with Rails Association

  - by tshauck

  Hi, I've been going through the Rails Guides, but have gotten stuck on associations after going through validations and migrations. So, I have the following models Job and Person, where a Person can have many jobs. I know that in reality there'd be a many-to-many, but I'm trying to get my handle on this first. class Job < ActiveRecord::Base belongs_to :people end and class Person < ActiveRecord::Base has_many :jobs end Here's the schema ActiveRecord::Schema.define(:version => 20110108185924) do create_table "jobs", :force => true do |t| t.string "occupation" t.boolean "like" t.datetime "created_at" t.datetime "updated_at" t.integer "person_id" end create_table "people", :force => true do |t| t.string "first_name" t.string "last_name" t.datetime "created_at" t.datetime "updated_at" end end Is there some I can do the following j = Job.first; j.Person? Then that'd give me access to the Person object associated with the j. I couldn't find it on guides.rubyonrails.org, although it has been very helpful getting a grip on migrations and validations thus far. Thanks PS, If there are any tutorials that covers more of this kind of things links would be great.

• Rails how to return a list of answers with a specific question_id

  - by mytwocentsisworthtwocents

  Let's say I have two Models, Answers and Questions (there are others, but irrelevant to the question). The models are as follows: Answer.rb class Answer < ActiveRecord::Base attr_accessible :description, :question_id has_one :question, :through => :user, :dependent => :destroy validates :description, :presence => true end Question.rb class Question < ActiveRecord::Base attr_accessible :budget, :description, :headline, :user_id, :updated_at, :created_at belongs_to :user has_many :answers validates :headline, :description, :user_id, :presence => true end I'd like to display on a page a list of all answers associated with a question, and only those questions. I got this far. I believe this variable finds all the questions in the database by the question_id (foreign key): @findanswers = Answer.all(params[:question_id]) And this one grabs the the id of the current question (this code will reside as an ERB on the page where the current question is located): @questionshow = Question.find(params[:id]) And now I'm stuck. How do I put the two together so that I list all the answers with the current question id?

• What's wrong (or right) with this JS Object Pattern?

  - by unsane1

  Here's an example of the pattern I'm using in my javascript objects these days (this example relies on jQuery). http://pastie.org/private/ryn0m1gnjsxdos9onsyxg It works for me reasonably well, but I'm guessing there's something wrong, or at least sub-optimal about it, I'm just curious to get people's opinions. Here's a smaller, inline example of it: sample = function(attach) { // set internal reference to self var self = this; // public variable(s) self.iAmPublic = true; // private variable(s) var debug = false; var host = attach; var pane = { element: false, display: false } // public function(s) self.show = function() { if (!pane.display) { position(); $(pane.element).show('fast'); pane.display = true; } } self.hide = function() { if (pane.display) { $(pane.element).hide('fast'); pane.display = false; } } // private function(s) function init () { // do whatever stuff is needed on instantiation of this object // like perhaps positioning a hidden div pane.element = document.createElement('div'); return self; } function position() { var h = { 'h': $(host).outerHeight(), 'w': $(host).outerWidth(), 'pos': $(host).offset() }; var p = { 'w': $(pane.element).outerWidth() }; $(pane.element).css({ top: h.pos.top + (h.h-1), left: h.pos.left + ((h.w - p.w) / 2) }); } function log () { if (debug) { console.log(arguments); } } // on-instantiation let's set ourselves up return init(); } I'm really curious to get people's thoughts on this.

• Slow Gmail Attachment Download over HTTPS [closed]

  - by Todd

  It only affects Gmail. I have tested other HTTP, FTP and HTTPS websites and downloading is fine, at the exact same time the problem is affecting a Gmail attachment download. The symptoms include both: High waiting time, before the download starts (in the order of 30 seconds); AND Very slow download transfer speeds ( in the order of 1kbps) It's a very strange problem, and I didn't find any recent issues relating to Google Australia. The account works fine at another site with a different ISP, so it's either a computer configuration or ISP - I lean to the latter.

• C# Possible to have a generic return type?

  - by JL

  Here is a typical function that returns either true/false; private static bool hasValue() { return true; } Now on an error, I would like to return my own custom error object with definition: public class Failure { public string failureDateTime { get; set; } public string failureReason { get; set; } } I would have expected to be able to throw this custom object for example... private static bool hasValue() { throw new Failure(); } This is not possible, and I don't want to derive Failure from System.IO.Exception because of the inability to serialize an exception in C#. What is the best practice / or ideal solution to this problem. Should I just work with private static object? Or is there a cleaner way to return a custom object or bypass the typical return type on an error (not using System.IO.Exception)? Not entirely wild about object either, because then I need to cast the result and validate it by more boolean logic.

• Flash automatically names objects on stage "instance#"

  - by meowMIX3R

  Hi, I have 2 TLF text boxes already placed on my main stage. In the property inspector window I give these the instance names: "txt1" and "txt2". I am trying to have a single mouseup event, and figure out which text box it occurred on. My document class has the following code: package { import flash.display.Sprite; import flash.events.KeyboardEvent; public class SingleEvent extends Sprite{ public function SingleEvent() { // constructor code root.addEventListener(KeyboardEvent.KEY_UP, textChanged,false,0,true); } private function textChanged(e:KeyboardEvent){ trace(e.target.name); trace(" " + e.target); switch(e.target){ case txt1: trace("txt1 is active"); break; case txt2: trace("txt2 is active"); break; default: break; } } } } Example output is: instance15 [object Sprite] instance21 [object Sprite] Since the objects are already on the stage, I am not sure how to get flash to recognize them as "txt1" and "txt2" instead of "instance#". I tried setting the .name property, but it had no effect. In the publish settings, I have "Automatically declare stage instances" checked. Also, is it possible to have a single change event for multiple slider components? The following never fires: root.addEventListener(SliderEvent.CHANGE, sliderChanged,false,0,true); Thanks for any tips

• Gmail Sync on Android phone

  - by sunocky

  Android has the Gmail push features, which means the new message arrives in the mailbox without checking or refreshing the mailbox. As I understand, the sync processes are like these: 1) User turns on the sync 2) There will be a alert msg and the sync flag in the Gmail DB of this device will be True 3) When a new email reach the Gmail Server, it will check if the device sync value, if it's True then send the email OK, here, I don't quite understand how exactly does it work, For a WiFi and cell signal connection, does the phone has a TCP socket open keep listening to the Gmail Server, or when a new email arrives the Server send a SMS alert to the phone, and then it will open the data channel to fetch the email? Are the two ways of connections have different approaches? And second question is which method is the priority one? Say when you are in the middle of receiving data(emails), and suddenly the phone connect to a wireless network, will the data socket be closed and then reopened for the WiFi one? What's the behavior for the case when carrier's data channel and WiFi flips? I have also downloaded the source code, anyone knows which part should I be looking into in order to solves my questions? I found a folder called "email" inside the folder "package", should I be looking at its code? I know I asked quite some questions here, I'd appreciate if you know the answer for any of them, thanks very much!

• How to match words as if in a dictionary, based on len-1 or len+1? Python

  - by pearbear

  If I have a word 'raqd', how would I use python to have a spellcheck, so to speak, to find the word 'rad' as an option in 'spellcheck'? What I've been trying to do is this: def isbettermatch(keysplit, searchword): i = 0 trues = 0 falses = 0 lensearchwords = len(searchword) keysplits = copy.deepcopy(keysplit) searchwords = copy.deepcopy(searchword) #print keysplit, searchwords if len(keysplits) == len(searchwords)-1: i = 0 while i < len(keysplits): j = 0 while j < lensearchwords: if keysplits[i] == searchwords[j]: trues +=1 searchwords.pop(j) lensearchwords = len(searchwords) elif keysplits[i] != searchwords[j]: falses +=1 j +=1 i +=1 if trues >= len(searchwords)-1: #print "-------------------------------------------------------", keysplits return True keysplit is a list like ['s', 'p', 'o', 'i', 'l'] for example, and the searchword would be a list ['r', 'a', 'q', 'd']. If the function returns True, then it would print the keyword that matches. Ex. 'rad', for the searchword 'raqd'. I need to find all possible matches for the searchword with a single letter addition or deletion. so ex. 'raqd' would have an option to be 'rad', and 'poted' could be 'posted' or 'potted'. Above is what I have tried, but it is not working well at all. Help much appreciated!
