  • Ruby (with Rails) convert a string of time into seconds?

    - by Ryan
    So, I've got a string of time... something along the lines of '4 hours' '48 hours' '3 days' '15 minutes' I would like to convert those all into seconds. For '4 hours', this works fine Time.parse('4 hours').to_i - Time.prase('0 hours').to_i => 14400 # 4 hours in seconds, yay However, this doesn't work for 48 hours (outside of range error). It also does not work for 3 days (no information error), etc. Is there a simple way to convert these strings into seconds?

  • How to restore files that were removed by git?

    - by Ryan
    I am a git noob and git just deleted a bunch of important files. How do I get them back? I have a repo on my local machine. To get into git, I just right click my project folder and select "git bash here". This brings up the master where I do all my giting. So I had some changes to stage and I did: git add . This staged a bunch of changes. I noticed that I didn't want some of these staged so I decided that I'd try to unstage everthing. I did this: git reset --hard HEAD^ This basically deleted a bunch of files that I had made on the last commit and jumped to the commit before. How do I get those files back? If I can't do it through git is there another way?

  • What type of programs are C/C++ used for now?

    - by Ryan Detzel
    I started off with C in school, went to Java and now I primarily use the P's(Php, Perl, Python) so my exposure to the lower level languages have all but disappeared. I would like to get back into it but I can never justify using C over Perl or Python. What real-world apps are being built with these languages? Any suggestions if I want to dive back in, what can I do with C/C++ that I can't easily do with Perl/Python?

  • Mapping to a different view based on child type

    - by Ryan Burnham
    So i have a situation where i have common base type but i need to map to a different view based on the child type. It looks like i can use a generic mapping class to handle the inheritance http://geekswithblogs.net/nharrison/archive/2010/07/09/inheriting-a-class-map-in-fluent-nhibernate.aspx But how can i conditionally map to a different view based on the child type? I see an EntityType property but it says its obsolete and will be made private in the next version. As an example i have a base class of ContactInfo is standard between contact types but the values come from different places depending on the contact type, this I'll handle through the sql view.

  • Sending a message to nil?

    - by Ryan Delucchi
    As a Java developer who is reading Apple's Objective-C 2.0 documentation: I wonder as to what sending a message to nil means - let alone how it is actually useful. Taking an excerpt from the documentation: There are several patterns in Cocoa that take advantage of this fact. The value returned from a message to nil may also be valid: If the method returns an object, any pointer type, any integer scalar of size less than or equal to sizeof(void*), a float, a double, a long double, or a long long, then a message sent to nil returns 0. If the method returns a struct, as defined by the Mac OS X ABI Function Call Guide to be returned in registers, then a message sent to nil returns 0.0 for every field in the data structure. Other struct data types will not be filled with zeros. If the method returns anything other than the aforementioned value types the return value of a message sent to nil is undefined. Has Java rendered my brain incapable of grokking the explanation above? Or is there something that I am missing that would make this as clear as glass? Note: Yes, I do get the idea of messages/receivers in Objective-C, I am simply confused about a receiver that happens to be nil.

  • Align/Wrap images around div

    - by Ryan Phillips
    What I'm trying to achieve is a page with a div centered in the middle of the screen (720x360). This is done with jQuery using $(window).height() and $(window).width() and works perfectly. The next part is getting 180x180 images to fit around that middle div. These will fill the screen + beyond. I'm stuck on how to get these to align that way and I couldn't find a live example of anyone doing the same thing. So, is this even possible? Thanks, Any help is appreciated!

  • Selecting records in SQL that have the minimum value for that record based on another field

    - by Ryan
    I have a set of data, and while the number of fields and tables it joins with is quite complex, I believe I can distill my problem down using the required fields/tables here for illustration regarding this particular problem. I have three tables: ClientData, Sources, Prices Here is what my current query looks like before selecting the minimum value: select c.RecordID, c.Description, s.Source, p.Price, p.Type, p.Weight from ClientData c inner join Sources s ON c.RecordID = s.RecordID inner join Prices p ON s.SourceID = p.SourceID This produces the following result: RecordID Description Source Price Type Weight ============================================================= 001002003 ABC Common Stock Vendor 1 104.5 Close 1 001002003 ABC Common Stock Vendor 1 103 Bid 2 001002003 ABC Common Stock Vendor 2 106 Close 1 001002003 ABC Common Stock Vendor 2 100 Unknwn 0 111222333 DEF Preferred Stk Vendor 3 80 Bid 2 111222333 DEF Preferred Stk Vendor 3 82 Mid 3 111222333 DEF Preferred Stk Vendor 2 81 Ask 4 What I am trying to do is display prices that belong to the same record which have the minimum non-zero weight for that record (so the weight must be greater than 0, but it has to be the minimum from amongst the remaining weights). So in the above example, for record 001002003 I would want to show the close prices from Vendor 1 and Vendor 2 because they both have a weight of 1 (the minimum weight for that record). But for 111222333 I would want to show just the bid price from Vendor 3 because its weight of 2 is the minimum, non-zero for that record. The result that I'm after would like like: RecordID Description Source Price Type Weight ============================================================= 001002003 ABC Common Stock Vendor 1 104.5 Close 1 001002003 ABC Common Stock Vendor 2 106 Close 1 111222333 DEF Preferred Stk Vendor 3 80 Bid 2 Any ideas on how to achieve this? EDIT: This is for SQL Compact Edition.

  • When my object is no longer referenced why do its events continue to run?

    - by Ryan Peschel
    Say I am making a game and have a base Buff class. I may also have a subclass named ThornsBuff which subscribes to the Player class's Damaged event. The Player may have a list of Buffs and one of them may be the ThornsBuff. For example: Test Class Player player = new Player(); player.ActiveBuffs.Add(new ThornsBuff(player)); ThornsBuff Class public ThornsBuff(Player player) { player.DamageTaken += player_DamageTaken; } private void player_DamageTaken(MessagePlayerDamaged m) { m.Assailant.Stats.Health -= (int)(m.DamageAmount * .25); } This is all to illustrate an example. If I were to remove the buff from the list, the event is not detached. Even though the player no longer has the buff, the event is still executed as if he did. Now, I could have a Dispel method to unregister the event, but that forces the developer to call Dispel in addition to removing the Buff from the list. What if they forget, increased coupling, etc. What I don't understand is why the event doesn't detatch itself automatically when the Buff is removed from the list. The Buff only existed in the list and that is its one reference. After it is removed shouldn't the event be detached? I tried adding the detaching code to the finalizer of the Buff but that didn't fix it either. The event is still running even after it has 0 references. I suppose it is because the garbage collector had not run yet? Is there any way to make it automatic and instant so that when the object has no references all its events are unregisted? Thanks.

  • Div not expanding even with content inside

    - by Aiden Ryan
    I have a stack of divs inside of each other, all of which have an ID which specifies CSS only. But for some reason the surrounding DIV tag only expands to it's anointed height value, and not it's default auto, meaning that although the content is inside, the backing DIV is only a specific height. I need it to adjust the heigh to the size of whatever is inside of it (As there will be user submitted data being echoed out possibly in paragraphs with 500+ words.) Here is my HTML <div id="albumhold"> <div id="albumpic">Pic here</div> <div id="infohold"> <div id="albumhead">Name | Date</div> <div id="albuminfo">Information</div> </div> And the CSS for the HTML code: #albumhold { width: 920px; padding: 10px; height: auto; border: 1px solid #E1E1E1; margin-left: auto; margin-right: auto; background-color: #E1E1E1; background-image: url(../global-images/albumback.png); background-position: top center; background-repeat: repeat-x; } #albumpic { display: block; height: 110px; width: 110px; float: left; border: 1px solid #000; } #infohold { width: 800px; background-color: #CCC; float: right; height: 20px; } #albumhead { width: 800px; height: 20px; text-indent: 10px; border: 1px solid #000; color: #09F; } #albuminfo { margin-top: 5px; width: 800px; float: right; color: #09F; word-wrap:break-word; } Help is greatly appreciated.

  • PHP string enocding issue - Extra characters appearing

    - by ryan
    I see extra characters like â showing because of encoding issues as I found out here - HTML encoding issues - "Â" character showing up instead of "&nbsp;" I understand that if I set the browser meta encoding to UTF-8, these will not affect anything but I need to strip these extra characters from the database for other purposes. For eg. : Text: ↑ should be become Text: ? But if I run it through utf8_decode it gives me Text: ??? For every other occurrence of the â character, it converts properly to a blank space. Any help will be appreciated.

  • Prototype 'on show' Event.observe handler

    - by ryan
    I am trying to make an AJAX request that updates a div's content when that div is shown. My initial thought was to use an Event observer that watched for a div to be shown, but I cannot seem to find an appropriate handler. Is there an easy way to make an AJAX request for an element 'on show?'

  • Can I use accepts_nested_attributes_for with checkboxes in a _form to select potential 'links' from a list

    - by Ryan
    In Rails 3: I have the following models: class System has_many :input_modes # name of the table with the join in it has_many :imodes, :through => :input_modes, :source => 'mode', :class_name => "Mode" has_many :output_modes has_many :omodes, :through => :output_modes, :source => 'mode', :class_name => 'Mode' end class InputMode # OutputMode is identical belongs_to :mode belongs_to :system end class Mode ... fields, i.e. name ... end That works nicely and I can assign lists of Modes to imodes and omodes as intended. What I'd like to do is use accepts_nested_attributes_for or some other such magic in the System model and build a view with a set of checkboxes. The set of valid Modes for a given System is defined elsewhere. I'm using checkboxes in the _form view to select which of the valid modes is actually set in imodes and omodes . I don't want to create new Modes from this view, just select from a list of pre-defined Modes. Below is what I'm currently using in my _form view. It generates a list of checkboxes, one for each allowed Mode for the System being edited. If the checkbox is ticked then that Mode is to be included in the imodes list. <% @allowed_modes.each do |mode| %> <li> <%= check_box_tag :imode_ids, mode.id, @system.imodes.include?(modifier), :name => 'imode_ids[]' %> <%= mode.name %> </li> <% end %> Which passes this into the controller in params: { ..., "imode_ids"=>["2", "14"], ... } In the controller#create I extract and assign the Modes that had their corresponding checkboxes ticked and add them to imodes with the following code: @system = System.new(params[:system]) # Note the the empty list that makes sure we clear the # list if none of the checkboxes are ticked if params.has_key?(:imode_ids) imodes = Mode.find(params[:imode_ids]) else imodes = [] end @system.imodes = imodes Once again that all works nicely but I'll have to copy that cludgey code into the other methods in the controller and I'd much prefer to use something more magical if possible. I feel like I've passed off the path of nice clean rails code and into the forest of "hacking around" rails; it works but I don't like it. What should I have done?

  • Can I use Jquery to automatically find and set the width and height of a variety of images?

    - by Ryan
    I am using the Masonry Plugin and for it to work correctly with images, you need to set the width and height within the image tag. All the image's heights will vary, but the width will be set at 200px. Is there a way for Jquery to detect the height of each image and set it's height? That way I don't have to go set the height of every single image. Does this make sense? Hope someone can help! I am new to Jquery.

  • Drop down menu like the default iPad application menus

    - by Ryan French
    Hi Everyone, I'm currently working on my first iOS application to run on the iPad, and I've come across a problem. I have been asked to implement menu's similar to the ones in the default applications such as when you click on the "Calendars" button in the top left of the calendars app. Only issue is, I cant seem to find a standard UI object that looks like these, with the arrow connecting the menu to the button etc. Is this a standard UI component that I should be able to use, or will I have to imitate them by creating a custom object? Thanks for any help.

  • How to remove NSDate objects from a NSMutableArray

    - by Ryan
    I have been working with NSArrays and NSMutableArrays that store NSDate objects for a few days now. I noticed that calling [listOfDates removeObject:date1] removes all the NSDate objects from the array. I have instead been doing this to remove objects: NSMutableArray *dateList; // Has Dates in it NSDate *dateToRemove; // Date Object to Remove __block NSUInteger indexToRemove; __block BOOL foundMatch = NO; [dateList enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { if ([obj isEqualToDate:dateToRemove]) { indexToRemove = idx; foundMatch = YES; *stop = YES; } }]; if (foundMatch) { [dateList removeObjectAtIndex:indexToRemove]; } Is there a better way to be doing this? Perhaps another data structure? Or a simpler function?

  • MySQL: Return grouped fields where the group is not empty, efficiently

    - by Ryan Badour
    In one statement I'm trying to group rows of one table by joining to another table. I want to only get grouped rows where their grouped result is not empty. Ex. Items and Categories SELECT Category.id FROM Item, Category WHERE Category.id = Item.categoryId GROUP BY Category.id HAVING COUNT(Item.id) > 0 The above query gives me the results that I want but this is slow, since it has to count all the rows grouped by Category.id. What's a more effecient way? I was trying to do a Group By LIMIT to only retrieve one row per group. But my attempts failed horribly. Any idea how I can do this? Thanks

    I would like to select from two tables and display my result using this query: CREATE TABLE Buy_Table ( buy_id int identity primary key, user_id int, amount decimal (18,2) ); go INSERT INTO Buy_Table (user_id, amount) VALUES ('1', 10), ('1', 8), ('1', 20), ('3', 1), ('2', 2); go CREATE TABLE Sell_Table ( sell_id int identity primary key, user_id int, amount decimal (18,2) ); go INSERT INTO Sell_Table (user_id, amount) VALUES ('1', 10), ('1', 8), ('1', 20), ('3', 3), ('2', 3); go select [user_id], 'Buy' as [Type], buy_id as [ID], amount from Buy_Table union all select [user_id], 'Sell', sell_id, amount from Sell_Table order by [user_id], [ID], [Type] However the above query will return each row of the user_id like this I want to display my result to something like this in a grid: Can this be done in query itself rather manipulating the grid?

  • Why does SQL Server consider N'????' and N'???' to be equal?

    - by Aidan Ryan
    We are testing our application for Unicode compatibility and have been selecting random characters outside the Latin character set for testing. On both Latin and Japanese-collated systems the following equality is true (U+3422): N'????' = N'???' but the following is not (U+30C1): N'????' = N'???' This was discovered when a test case using the first example (using U+3422) violated a unique index. Do we need to be more selective about the characters we use for testing? Obviously we don't know the semantic meaning of the above comparisons. Would this behavior be obvious to a native speaker?
