  • Packing differently sized chunks of data into multiple bins

    - by knizz
    EDIT: It seems like this problem is called "Cutting stock problem" I need an algorithm that gives me the (space-)optimal arrangement of chunks in bins. One way would be put the bigger chunks in first. But see how that algorithm fails in this example: Chunks Bins ----------------------------- AAA BBB CC DD ( ) ( ) Algorithm Result ----------------------------- biggest first (AAABBB ) (CC ) optimal (AAACCDD) (BBB) "Biggest first" can't fit in DD. Maybe it helps to build a table like this: Size 1: --- Size 2: CC, DD Size 3: AAA, BBB Size 4: CCDD Size 5: AAACC, AAADD, BBBCC, BBBDD Size 6: AAABBB Size 7: AAACCDD, BBBCCDD Size 8: AAABBBCC, AAABBBDD Size 10: AAABBBCCDD

  • Can one form have multiple actions?

    - by Brook Julias
    I am wanting to submit a form to different places based on selections made in the form. If the user wants to delete elements go to page 1. If the user wants to edit/update elements go to page 2. If the user wants to group/attach elements go to page 3.

  • Multiple developers on a Titanium project

    - by Cybear
    I'm making an iPhone app with Appcelerator Titanium and I want to share the source code with a few more programmers. I will use a SCM repository which at some point might be open to the general public. Now my question is, are there any files which I should not commit to the repository? In project root I can tell that tiapp.xml and mainfest are telling the app GUID, is there any reason for me to keep that private? (this value is also shown many places in the build/ folder) I've added everything in the Resources/ folder. If I skip the build/iphone/build/ folder, will developers still be able to build the project? Side question - When another programmer downloads this code, it seems to me that (s)he has to have the same directory structure as I do? Any workarounds for this?

  • Ant - using vssadd to add multiple file

    - by mamendex
    Hi, I'm trying to use vssadd task to add a tree of source files to a recent created project on VSS. But it happens to be adding only the folder tree, all files missing. <vsscp vsspath="$/DEV/APL_${version}" ssdir="${vssapl}" serverPath="${vsssvr}"/> The vssadd task displays the name of the folders it's creating: ... (vssadd) $/DEV/APL_0.0.10c/src/domain: (vssadd) $/DEV/APL_0.0.10c/src/mbeans: (vssadd) $/DEV/APL_0.0.10c/src/service: ... The script runs successfully but the files never get in the repository. Trying to use wilcards are no good, the task says it found no matching files and ss returns with a code of 100: <vssadd ssdir="${vssapl}" localPath="C:\Workspace\APL_Build*.*" recursive="true" serverPath="${vsssvr}" comment="Build ${versao} at ${to.timestamp}"/ I've noticed that vssadd does not accept fileset tag either, so I'm kind of lost here. Any tips? tks

  • How do I do multiple assignment in MATLAB?

    - by Benjamin Oakes
    Here's an example of what I'm looking for: >> foo = [88, 12]; >> [x, y] = foo; I'd expect something like this afterwards: >> x x = 88 >> y y = 12 But instead I get errors like: ??? Too many output arguments. I thought deal() might do it, but it seems to only work on cells. >> [x, y] = deal(foo{:}); ??? Cell contents reference from a non-cell array object. How do I solve my problem? Must I constantly index by 1 and 2 if I want to deal with them separately?

  • Fact table with multiple facts

    - by Jeff Meatball Yang
    I have a dimension (SiteItem) has two important facts: perUserClicks perBrowserClicks however, within this dimension, I have groups of dimensions based on an attribute column (let's call the groups AboveFoldItems, LeftNavItems, OnTheFlyItems, etc.) each have more facts that are specific to that group: AboveFoldItems: eyeTime, loadTime LeftNavItems: mouseOverTime OnTheFlyItems: doesn't have any extra, but may in the future Is the following fact table schema ok? DateKey SessionKey SiteItemKey perUserClicks perBrowserClicks eyeTime loadTime mouseOverTime It seems a little wasteful since only some columns pertain to some dimension keys (the irrelevant facts are left NULL). But... this seems like it would be a common problem, so there should be a common solution for this, right?

  • Organizing multiple embed codes with jQuery

    - by Nimbuz
    I have several embed codes on my website, for example: Embed Code #1: <object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/f8Lp2ssd5A9ErAc&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/f8Lp2A9ErAc&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object> Embed Code #2: <script type="text/javascript"> _qoptions={ qacct:"p-3asdb5E0g6" }; </script> <script type="text/javascript" src="http://edge.quantserve.com/quant.js"></script> <noscript> <a href="http://www.quantcast.com/p-3asdb5E0g6" target="_blank"><img src="http://pixel.quantserve.com/pixel/p-3asdb5E0g6.gif" style="display: none;" border="0" height="1" width="1" alt="Quantcast"/></a> </noscript> and so on.. How do organize them and separate them into an external single js file to keep the markup clean? Thanks for your help!

  • A better way to delete a list of elements from multiple tables

    - by manyxcxi
    I know this looks like a 'please write the code' request, but some basic pointer/principles for doing this the right way should be enough to get me going. I have the following stored procedure: CREATE PROCEDURE `TAA`.`runClean` (IN idlist varchar(1000)) BEGIN DECLARE EXIT HANDLER FOR NOT FOUND ROLLBACK; DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK; DECLARE EXIT HANDLER FOR SQLWARNING ROLLBACK; START TRANSACTION; DELETE FROM RunningReports WHERE run_id IN (idlist); DELETE FROM TMD_INDATA_INVOICE WHERE run_id IN (idlist); DELETE FROM TMD_INDATA_LINE WHERE run_id IN (idlist); DELETE FROM TMD_OUTDATA_INVOICE WHERE run_id IN (idlist); DELETE FROM TMD_OUTDATA_LINE WHERE run_id IN (idlist); DELETE FROM TMD_TEST WHERE run_id IN (idlist); DELETE FROM RunHistory WHERE id IN (idlist); COMMIT; END $$ It is called by a PHP script to clean out old run history. It is not particularly efficient as you can see and I would like to speed it up. The PHP script gathers the ids to remove from the tables with the following query: $query = "SELECT id, stop_time FROM RunHistory WHERE config_id = $configId AND save = 0 AND NOT(stop_time IS NULL) ORDER BY stop_time"; It keeps the last five run entries and deletes all the rest. So using this query to bring back all the IDs, it determines which ones to delete and keeps the 'newest' five. After gathering the IDs it sends them to the stored procedure to remove them from the associated tables. I'm not very good with SQL, but I ASSUME that using an IN statement and not joining these tables together is probably the least efficient way I can do this, but I don't know enough to ask anything but "how do I do this better?" If possible, I would like to do this all in my stored procedure using a query to gather all the IDs except for the five 'newest', then delete them. Another twist, run entries can be marked save (save = 1) and should not be deleted. The RunHistory table looks like this: CREATE TABLE `TAA`.`RunHistory` ( `id` int(11) NOT NULL auto_increment, `start_time` datetime default NULL, `stop_time` datetime default NULL, `config_id` int(11) NOT NULL, [...] `save` tinyint(1) NOT NULL default '0', PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8;

  • PHP: passing GET between multiple pages

    - by aterimperator
    I'm building a set of pages where I have a number of GET variables and it is often valuable to keep passing it along to the next page. This leads to ugly code where I have to have "if this $_GET variable is set, dynamically add it to this hyperlink". This is, in many senses, not a problem; but I had the thought "there must be a better way to do this", I mean after all basically all I want is to take the '?' and everything after it and append it to the links on that page, it would seem this should be rather simple (or at least possible to do in a for loop). I tried google searching but couldn't find anything, so I figured I'd see if any of you happen to know. Why not use SESSION? Because these pages need to be capable of being bookmarked. Thank you.

  • WCF Web Services - Multiple Hop impersonation on the same server

    - by Lerxst
    Hi Folks I have 3 web services, all located on the same server. My Client calls Service A, which impersonates the client to call Service B, and all is well. Now, I want to impersonate the caller of service B (which is my username) to call Service C. When I use the same technique as before (AllowedImpersonationLevel = Impersonate, user.Impersonate()), The user doesnt get passed to service C. Instead, Service C sees the user as the user I am running it under in IIS. Is there anything special I need to do to get this working? Is this a delegation issue? (I thought it would not be delegation because they are all on the same server) Thanks SO!

  • use multiple xsl files with one xml document

    - by paracaudex
    I have a single xml document (data.xml), which I display as HTML using an XSLT document (transform.xsl) with the following line in data.xml. <?xml-stylesheet type="text/xsl" href="transform.xsl"?> Suppose, however, I want to display this information in two different ways, one at http://www.domain.com/data.xml and one at http://www.domain.com/data2.xml. Both of these displays will use the same xml document but with different xsl's. Is there a way to do this without duplicating the xml file?

  • Jquery Close/Open Multiple Toggles

    - by Pedro
    Hi, I have the toggle in my menu Working successfully for the two links that I have within it. Because the top link once toggled covers the other link, there is no problem. But since the link beneath it leaves the top link exposed, a user could click that and now have two toggled items open and pretty much stacked on top of each other. Is there a way for me to check if the other toggled item is open and if so, close it? Thanks! <div class="parents-toggle"> <a href="#" id="customize-toggle">Customize</a><br/> <div class="menu-toggle hidden" id="customize-menu"> <div class="menu-toggle-one"> <h3>Background</h3> <ul> <li><a href="#">Dark Wood</a></li> <li><a href="#">Wallpaper</a></li> <li><a href="#">Bricks</a></li> <li><a href="#">Planks</a></li> <li><a href="#">Default</a></li> </ul> </div> <div class="menu-toggle-two"> <h3>Layout</h3> <ul> <li><a href="#">Grid</a></li> <li><a href="#">List</a></li> <li><a href="#">Full</a></li> </ul> </div> </div> </div> <a href="/submit/">Submit video</a><br/> <div class="parents-toggle"> <a href="#" id="channels-toggle">Channels</a> <div class="menu-toggle hidden" id="channels-menu"> <div class="menu-toggle-one"> <ul> <li><a href="#">Automotive</a></li> <li><a href="#">Comedy</a></li> <li><a href="#">Movies</a></li> <li><a href="#">Weather</a></li> </ul> </div> <div class="menu-toggle-two"> <ul> <li><a href="#">Business</a></li> <li><a href="#">Commercials</a></li> <li><a href="#">Music</a></li> <li><a href="#">Technology</a></li> </ul> </div> </div> </div> </div> <script> $("#customize-toggle").click(function () { $("#customize-menu").toggle(); }); $("#channels-toggle").click(function () { $("#channels-menu").toggle(); }); </script>

  • Retrieving multiple rows in SQL Server but distinct filtering only on one

    - by Nicklas
    I have this: SELECT Product.ProductID, Product.Name, Product.GroupID, Product.GradeID, AVG(tblReview.Grade) AS Grade FROM Product left Join tblReview ON Product.GroupID = tblReview.GroupID WHERE (Product.CategoryID = @CategoryID) GROUP BY Product.ProductID, Product.Name, Product.GroupID, Product.GradeID I would like to return only the rows where Product.Name is unique. If I make a SELECT DISTINCT the ProductID is different on every row so all the rows are unique.

  • Python style: multiple-line conditions in IFs

    - by Eli Bendersky
    Hello, Sometimes I break long conditions in IFs to several lines. The most obvious way to do this is: if (cond1 == 'val1' and cond2 == 'val2' and cond3 == 'val3' and cond4 == 'val4'): do_something Isn't very very appealing visually, because the action blends with the conditions. However, it is the natural way using correct Python indentation of 4 spaces. Edit: By the way, for the moment I'm using: if ( cond1 == 'val1' and cond2 == 'val2' and cond3 == 'val3' and cond4 == 'val4'): do_something Not very pretty, I know :-) Can you recommend an alternative way ?

  • Usage of closures with multiple arguments in swift

    - by Nilzone-
    This question is largely based on this one: Link The main difference being that I want to pass in arguments to the closure as well. Say I have something like this: func someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> ()) { // function body goes here var error: NSError? let responseDictionary: Dictionary<String, AnyObject> = ["test" : "test2"] completionClosure(venues: responseDictionary, error: error!) } No error here. But when I call this function in my main view controller I have tried several ways but all of the result in different errors: venueService.someFunctionThatTakesAClosure(completionClosure(venues: Dictionary<String, AnyObject>, error: NSError){ }) or like this: venueService.someFunctionThatTakesAClosure((venues: Dictionary<String, AnyObject>, error: NSError){ }) or even like this: venueService.someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> (){ }); I'm probably just way tired, but any help would be greatly appreciated!

  • Mapping multiple keys to the same value in a Javascript hash

    - by Bears will eat you
    I use a Javascript hash object to store a set of numerical counters, set up like this [this is greatly simplified]: var myHash = { A: 0, B: 0, C: 0 }; Is there a way to make other keys, ones not explicitly in myHash, map to keys that are? For instance, I'd like [again, this is simplified]: myHash['A_prime']++; // or myHash.A_prime++; to be exactly equivalent to myHash['A']++; // or myHash.A++; e.g. incrementing the value found at the key A, not A_prime.

  • Jquery autocomplete UI - No results on multiple fields

    - by pjammer
    Andrew's answer to my comment has sparked this question. According to his awesome answer in the link above, the code at the bottom of the question will only work for ONE widget. But it's killer nice code and makes sense... I guess I want the best of both worlds. Nice JS, (if that is possible) and to have the zero results show() just the element that we're using at the time. This code snippet is the main crux of my problem, as I see it: source: function (request, response) { jQuery.ajax({ url: "/autocomplete.json", data: { term: request.term }, success: function (data) { if (data.length == 0) { jQuery('span.guest_investor_email').show(); jQuery('span.investor_field_delete_button').show(); } response(data); } }); Currently: I have a button on my page that says "Add more Information" and each time you click it, a new instance of the autocomplete text field appears, complete with some hidden fields and a display:none; on guest_investor_email. If I use the autocomplete text field, say 3 times, and i have 3 autocomplete instances on the page and the third one finds 0 results: The code will show() all 3 instances of the guest_investor_email text field, instead of just this one that is blank. QUESTION: How do i get something like jQuery(this).siblings(('span.guest_investor_email').show(); to work? this is an Object and not an array of elements to select. If it isn't with this I don't mind, as long as I know how to get at it. Thanks. Full Code: jQuery(".auto_search_complete").live("click", function() { jQuery(this).autocomplete({ minLength: 3, source: function (request, response) { jQuery.ajax({ url: "/autocomplete.json", data: { term: request.term }, success: function (data) { if (data.length == 0) { jQuery('span.guest_investor_email').show(); jQuery('span.investor_field_delete_button').show(); } response(data); } }); }, focus: function(event, ui) { jQuery(this).val(ui.item.user ? ui.item.user.name : ui.item.pitch.name); return false; }, select: function(event, ui) { jQuery(this).val(ui.item.user ? ui.item.user.name : ui.item.pitch.name); jQuery(this).siblings('div.hidden_fields').children('.poly_id').val(ui.item.user ? ui.item.user.id : ui.item.pitch.id); jQuery(this).siblings('div.hidden_fields').children('.poly_type').val(ui.item.user ? "User" : "Pitch"); jQuery(this).siblings('span.guest_investor_email').hide(); jQuery(this).siblings('span.investor_field_delete_button').show(); jQuery(this).attr('readonly','readonly'); jQuery(this).attr('id', "investor-selected"); return false; } }).each(function() { jQuery(this).data( "autocomplete" )._renderItem = function( ul, item ) { return jQuery( "" ) .data( "item.autocomplete", item ) .append("" + (item.user ? item.user.name : item.pitch.name) + "" + (item.user ? item.user.investor_type : item.pitch.investor_type) + " - " + (item.user ? item.user.city : item.pitch.city) + "" ) .appendTo( ul ); }; }); });

  • Assign Multiple Custom User Roles to a Custom Post Type

    - by OUHSD Webmaster
    Okay here's the situation.... I'm working on a my business website. There will be a work/portfolio area. "Work" is a custom post type. "Designer" is a custom user role. "Client" is a custom user role. In creating a new "Work" post I would like to be able to select both a "designer" and "Client" to assign to the piece of work, as I would assign an author to a regular ol' post.

  • Checking multiple conditions in Ruby (within Rails, which may not matter)

    - by Ev
    Hello rubyists and railers, I have a method which checks over a params hash to make sure that it contains certain keys, and to make sure that certain values are set within a certain range. This is for an action that responds to a POST query by an iPhone app. Anyway, this method is checking for about 10 different conditions - any of which will result in an HTTP error being returned (I'm still considering this, but possibly a 400: bad request error). My current syntax is basically this (paraphrased): def invalid_submission_params?(params) [check one] or [check two] or [check three] or [check four] etc etc end Where each of the check statements returns true if that particular parameter check results in an invalid parameter set. I call it as a before filter with params[:submission] as the argument. This seems a little ugly (all the strung together or statements). Is there a better way? I have tried using case but can't see a way to make it more elegant. Or, perhaps, is there a rails method that lets me check the incoming params hash for certain conditions before handing control off to my action method?

  • storing multiple values as binary in one field

    - by Enghoej
    Hi I have a project where I need to store a large number of values. The data is a dataset holding 1024 2Byte Unsigned integer values. Now I store one value at one row together with a timestamp and a unik ID. This data is continously stored based on a time trigger. What I would like to do, is store all 1024 values in one field. So would it be possible to do some routine that stores all the 1024 2byte integer values in one field as binary. Maybe a blobfield. Thanks. Br. Enghoej
