• Can jQuery perform a compound select against the top level only? (a.k.a. "How to avoid chaining chil

  - by harpo

  Basically, is there a way to write a.children('.outer').children('.inner') without the intermediate selector? I can't write $('.outer > .inner', a) because I don't want to do full-depth search against a — I know that the .outer elements are immediate children of a. It's partly a matter of "elegance", but partly because I'm trying to avoid "throwaway" element sets. Yes, jQuery may in effect do the same thing, but it has a better chance of optimizing (at least in theory), when it knows the full query's intent.

• Building a "lecture notes" website with wordpress

  - by Tal Galili

  Hi all, I wish to build a "lecture notes" website using wordpress. And would love for any advice on what plugins to use, other considerations to have or website that perform a similar task with WP. The website should have a form that will allow users to upload their lecture files. The results should be a new "post". When submitting the form, the users should be able to tag their subject matter so to allow others to search it. Any suggestions will be welcomed. Thanks.

• Getting the most frequent items without counting every item

  - by DeadMonkeyWalkin

  Hi. I was wondering if there was an algorithm for counting "most frequent items" without having to keep a count of each item? For example, let's say I was a search engine and wanted to keep track of the 10 most popular searches. What I don't want to do is keep a counter of every query since there could be too many queries for me to count (and most them will be singletons). Is there a simple algorithm for this? Maybe something that is probabilistic? Thanks!

• How do you remove the Bing Disambiguation Dialog via API call?

  - by Justin Dearing

  I am integrating bing maps into a web page. I am calling the GetDirections() method of my VEMap option. and setting the VERouteOptions.ShowDisambiguation property to true when I call VEMap.GetDirections(). So sometimes I get the following dialog: The problem is sometimes the user will enter a second set of directions into my form, and dialog remains. I've done the following to attempt to correct it: // In case the disambiguation dialog a.k.a "" is present from a previous direction search var disambiguationDialogElement = $('#myMap_veplacelistpanel')[0]; if (typeof (disambiguationDialogElement) == "object") { map.DeleteControl(disambiguationDialogElement); } It seems to work, but it feels like a suboptomial approach. Is there a better way to do it?

• How can I write this Table Valued Function as a Stored Procedure?

  - by Alex

  I have the following TVF for fulltext search: FUNCTION [dbo].[Fishes_FullTextSearch] (@searchtext nvarchar(4000), @limitcount int) RETURNS TABLE AS RETURN SELECT * FROM Fishes INNER JOIN CONTAINSTABLE(Fishes, *, @searchtext, @limitcount) AS KEY_TBL ON Fishes.Id = KEY_TBL.[KEY] When I'm using this TVF, it doesn't return a collection of objects of type Fish (which I want!) - instead LINQ creates a new result type which includes all "Fish" fields and the fields Key and Rank. In another question, it was suggested that I rewrite this TVF into a stored procedure for it to return Fish objects only. Can someone help me do this please? Also, it needs to be ordered by Rank. Thank you!

• Download Specific Images

• Finding relative libraries when using symlinks to ruby executables

  - by dgtized

  Imagine you have an executable foo.rb, with libraries bar.rb layed out in the following manner: <root>/bin/foo.rb <root>/lib/bar.rb In the header of foo.rb you place the following require to bring in functionality in bar.rb: require File.dirname(__FILE__)+"../lib/bar.rb" This works fine so long as all calls to foo.rb are direct. If you put as say $HOME/project, and symlink foo.rb into $HOME/usr/bin, then __FILE__ resolves to $HOME/usr/bin/foo.rb, and is thus unable to locate bar.rb in relation to the dirname for foo.rb. I realize that packaging systems such as rubygems fix this by creating a namespace to search for the library, and that it is also possible to adjust the load_path using $: to include $HOME/project/lib, but it seems as if a more simple solution should exist. Has anyone had experience with this problem and found a useful solution or recipe?

• MVC framework for huge JEE application

  - by chaKa

  Which MVC-framework is the best option (performance/ease of development) for a web application, that will have + 2 million visits per week. Basically the site is a search engine,but also there will be large amounts of xml parsing, and high db traffic. We are using Java, over Jboss 4.2.3x, with PG as DB, and Solr for the searches. We were thinking on code JSPs with taglibs, and Servlets, but we were feeling like there would be a better alternative, which don't know yet, as we are starting on the Java Web applications world. Any opinions, and shares of your experience will be appreciated! Thanks in advance!

• thinking sphinx ordering by mixing capitals and lower case

  - by miccet

  I have a rails application that is using thinking_sphinx for the searching. My problem is that the result returned is sorted with capitals first and lower case after it at the bottom. I'd like to mix them so that both 'A' and 'a' comes before 'B'. This is the method I'm using: Company.search(query, :star => true, :page => params[:page], :per_page => 20, :order => :name, :sort_mode => :asc)

• How to enforce lazy loading of entities on certain conditions

  - by Samuel

  We have an JPA @Entity class (say User) which has a @ManyToOne reference (say Address) loaded using the EAGER option which in turn loads it's own @ManyToOne fields (say Country) in a EAGER fashion. We use the EntityQuery interface to count the list of User's based on a search criteria, during such a load all the @ManyToOne fields which have been marked as EAGER get loaded. But in order to perform a EntityQuery.resultCount(), I actually don't need to load the @ManyToOne fields. Is there a way to prevent loading of the EAGER fields in such cases so that we can avoid the unnecessary joins?

• How can I select a value matching my input from a TypeAhead control using WWW::Mechanize?

  - by kyoob

  So ordinarily the element I want to pick from a list would be populated on a page and I'd just find it and pick it. But I'm dealing with a control that doesn't populate list elements until some input has been stuck into a text box, after which it gives me a list of recommendations. For an example of the kind of list I'm talking about think of Facebook's "People, Places, and Things" search field. I want to plug a string into this text box, select the same string from the list of recommendations, and submit the form. The issue I'm having right now is I can't seem to get Mechanize to even recognize the field is there. I examine a dump of $mech->find_all_inputs and it isn't listed. Is this kind of field just beyond Mechanize's jurisdiction?

• WCF and a developer key like Google map API. What exactly am I looking for?

  - by Scott

  I want to allow access to a WCF service to only those requests that contain a developer key. This is similiar to how the Google Maps API works. Register for a developer key and include that key in your requests. Anyone can get a key. How you get a key is undecided but is being discussed. For now, we'll email you a key. The service is up and running so I will be adding this on. I just need to know what I'm looking for so I can figure out what I need to do. Makes sense, right?!?! What is this scheme called? What should I search for? Any suggested links / books / whitepapers?

• Form action with #hashtag not working in internet explorer

  - by Stephane

  I am using jquery-ui tabs and I've set it up to select the correct tab depending on the #hash from the requested URL. I have a form which performs a search, and each tab present the result from different providers. so if the form is submitting to the action "/myAction#tab1", when the results load, the corresponding tab gets selected. This works perfectly in every browser except for IE. When my form is submitted, it loses somehow the #hash which describes which tab to select. Is that yet another a bug from IE, or am I doing something wrong? I could not find much information about this, but I can hardly believe that this is not a common problem.

• Alternatives to C++ Reference/Pointer Syntax

  - by Jon Purdy

  What languages other than C and C++ have explicit reference and pointer type qualifiers? People seem to be easily confused by the right-to-left reading order of types, where char*& is "a reference to a pointer to a character", or a "character-pointer reference"; do any languages with explicit references make use of a left-to-right reading order, such as &*char/ref ptr char? I'm working on a little language project, and legibility is one of my key concerns. It seems to me that this is one of those questions to which it's easy for a person but hard for a search engine to provide an answer. Thanks in advance!

• databind a DropDownList control with a list of all sub directories that exist in a particular direct

  - by sushant

  I am wanting to databind a DropDownList control with a list of all sub directories that exist in a particular directory on the server. The directory I want to search is in the root of the application. I am fairly new to programming and I'm not sure where to even start. I found this code on a website: Dim root As String = "C;\" Dim folders() As String = Directory.GetDirectories(root) Dim sb As New StringBuilder(2048) Dim f As String For Each f In folders Dim foldername As String = Path.GetFileName(f) sb.Append("<option>") sb.Append(foldername) sb.Append("</option>") Next Label3.Text = "<select runat=""sever"" id=""folderlist""" & sb.ToString() & "</select>" I guess this is vb. but my tool is in asp, so is their something similar in vbscript so that I can use it.

• Where to install shared DLLs on Windows

  - by BruceCran

  I have a driver which can be installed on Windows (XP/Vista/7). It's accessed via a DLL that applications link to, and which is also a Winsock Provider (WSP). It used to be installed under System32, but having seen advice not to, I changed it to install under ProgramFiles instead. Now, the problem is that people are having to either copy it back into System32 or copy it into the application directory whenever they want to use it in their own applications, because Windows won't search the install directory under ProgramFiles when the application tries to load the DLL. I've been unable to find any Microsoft documentation discussing this issue, so if System32 shouldn't be used then where should shared DLLs be installed?

• 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?
