• MSSQL Search Proper Names Full Text Index vs LIKE + SOUNDEX

  - by Matthew Talbert

  I have a database of names of people that has (currently) 35 million rows. I need to know what is the best method for quickly searching these names. The current system (not designed by me), simply has the first and last name columns indexed and uses "LIKE" queries with the additional option of using SOUNDEX (though I'm not sure this is actually used much). Performance has always been a problem with this system, and so currently the searches are limited to 200 results (which still takes too long to run). So, I have a few questions: Does full text index work well for proper names? If so, what is the best way to query proper names? (CONTAINS, FREETEXT, etc) Is there some other system (like Lucene.net) that would be better? Just for reference, I'm using Fluent NHibernate for data access, so methods that work will with that will be preferred. I'm using MS SQL 2008 currently.

• Change input text to regular text on blur and ability to edit jQuery

  - by eknown

  I'm creating a form where I'm eliminating the use of a save button. The form is made up of input text boxes and textareas. After the user enters data into the input field, I want to trigger an onBlur function and change the input into a span that contains the information that the user entered. I also want to have the ability to edit this information, so if the user clicks on the newly created span with text, it will turn back into the input field with the current information for their editing pleasure. For reference, I'm looking to have a functionality pretty much like on editing a photo title on Flickr. If possible, I'd also like to have the textbox show "saving..." for half a second after the blur to reflect interaction with server.

• Sum value of XML attributes using PowerShell 2.0

  - by Yooakim

  I have a directory with XML files. I quickly want to go through them and sum upp the value stored in one attribute. I have figured out how to fidn the nodes I am interested in. For example: (Select-Xml -Path .\*.xml -XPath "//*[@Attribue = 'valueImlookingfor']").Count This command gives me the count of elements in all of the XML files in the current directory which has the value "valueImlookingfor" in the "Attribue". I want to sum up all the values of the "Attribute", not count them. What would be the best way to do this in PowerShell? I am new to PowerShell so this may be trivial but un-known to me... All tips are much appreciated :-)

• Serving files over HTTPS dynamically based on request.ssl? with Attachment_fu

  - by Marston A.

  I see there is a :user_ssl option in attachment_fu which checks the amazon_s3.yml file in order to serve files via https:// In the s3_backend.rb you have this method: def self.protocol @protocol ||= s3_config[:use_ssl] ? 'https://' : 'http://' end But this then makes it serve ALL s3 attachments with SSL. I'd like to make it dynamic depending if the current request was made with https:// i.e: if request.ssl? @protocol = "https://" else @protocol = "http://" end How can I make it work in this way? I've tried modifying the method and then get the NameError: undefined local variable or method `request' for Technoweenie::AttachmentFu::Backends::S3Backend:Module error

• NSIS Uninstaller Working Directory

  - by James Thigpen

  I am using NSIS to create my installers/uninstallers, and the uninstaller seems to have a weird behavior. I don't put the installer in $INSTDIR, it is located at $INSTDIR/subdir/uninstall.exe (it's a addon installer for a host application). When I run the installer then, it thinks the application installation root is $INSTDIR/subdir instead of $INSTDIR. It then can't find all the files in subdir/* as it's already in subdir. If I move the executable, it seems to just accept the current directory as where the application installation root is. I can move it to $INSTDIR and all is well. Thanks.

• ASP.NET MVC UpdateModel - fields vs properties??

  - by mrjoltcola

  I refactored some common properties into a base class and immediately my model updates started failing. UpdateModel() and TryUpdateModel() did not seem to update inherited public properties. I cannot find detailed info on MSDN nor Google as to the rules or semantics of these methods. The docs are terse (http://msdn.microsoft.com/en-us/library/dd470933.aspx), simply stating: Updates the specified model instance using values from the controller's current value provider. SOLVED: MVC.NET does indeed handle inherited properties just fine. This turned out to have nothing to do with inheritance. My base class was implemented with public fields, not properties. Switching them to formal properties (adding {get; set; }) was all I needed. This has bitten me before, I keep wanting to use simple, public fields. I would argue that fields and properties are syntactically identical, and could be argued to be semantically equivalent, for the user of the class.

• Having an online highscore leaderboard for a Flash game

  - by Marco Fox

  Why, hello there. I'm trying to develop a simple Flash game using Actionscript 2 (I know its a bit dated, but its a simple project that doesen't benefict much from AS3), and I came up with an ideia of implementing an online leaderboard that records and shows the highscore of the player. This isn't anything too complicated, but I seem to be having problem finding resources online that explain how I should implement this. All I want is a call, probably to a PHP/MySQL database that records the player's name (which will be recorded via a input window) and its current score. It would also have to show the best all time scores, by order. I should remind you that I am working on a Actionscript 2 so Actionscript 3 solutions are probably not going to work. Can anyone out there help me out here? Did any of you already been through this?

• Subversion commit conflict

  - by dvanaria

  I use Subversion mainly to synchronize work between two computers I use on a daily basis (and as a backup, since I have a checked-out copy of the repository on each computer). I keep the main repository on a USB flashdrive. I recently came across the following error when trying to commit a current working copy (and both working copies, one on each computer, are identical now): ! C career\UVaOnlineJudge\Log.doc local delete, incoming delete upon update ! C career\UVaOnlineJudge\102\Main.class local delete, incoming delete upon update Without going into more detail about what I did to get the repository out of synch, my question is more general. What does “local delete, incoming delete upon update” mean? What is Subversion expecting that I’m not giving it?

• Problem with connection to MS SQL Server database using SSMS

  - by Charles

  I have a database on line with Godaddy (who uses SQL Server 2005). They provide basic management tools, but tell you that for more advanced tools you can connect directly using SSMS. I followed their instructions to ensure my online database will accept remote connections, and can apparently log in using SSMS with success (after giving my hostname and access data). However: When attempting to expand the "Databases" folder tree, I get the following error: Failed to retrieve data for this request.

• Python: Remove items from a list while iterating in Python

  - by xApple

  My problem is simple: I have a long list of elements that I want to iterate through and check every element against a condition. Depending on the outcome of the condition I would like to delete the current element of the list, and continue iterating over it as usual. I have read a few other threads on this matter. Two solutions seam to be proposed. Either make a dictionary out of the list (which implies making a copy of all the data that is already filling all the RAM in my case). Either walk the list in reverse (which breaks the concept of the alogrithm I want to implement). Is there any better or more elegant way than this to do it ? def walk_list(list_of_g): g_index = 0 while g_index < len(list_of_g): g_current = list_of_g[g_index] if subtle_condition(g_current): list_of_g.pop(g_index) else: g_index = g_index + 1

• Replicating MySQL DB to development machine - bad idea?

  - by Joel

  I am considering replicating a production MySQL database to my development machine so I've always got current data. The production database is externally hosted. My development machine is behind an unreliable internet connection. It is entirely possible that the development machine could be disconnected from the internet for extended periods of time (hours). Would there be any adverse effect on the production database by doing this? (I don't strictly need live data - but it would be nice, and good excuse to dabble with replication. If the consensus is that this is a bad idea, I'll set up a daily job to import the previous night's backup into my development database)

• iPhone, JQTouch and HTML5 audio tags

  - by Moo

  I am having an issue with JQTouch (latest beta) and html5 audio tags on 'sub pages' - the audio tag works before any page transitions are done, and cease to work afterward. For example: http://richardprice.dyndns.ws/test.html and http://richardprice.dyndns.ws/test2.html are identical other than I swap the "current" class between the two divs - all the audio tags play the same mp3. On test.html the audio tag on the initial page works, but when you switch to Page 2 the audio tag on that page does not (and sometimes results in a browser crash). Switch back to Page 1 and the audio tag on that page has ceased to work. test2.html is the same test but with the initial pages reversed, and the same thing happens - Page 2 (now the initial page) plays the audio, Page 1 does not, and switching back to Page 2 results in the audio no longer working. Thoughts?

• How to mock test a web service in PHPUnit across multiple tests?

  - by scraton

  I am attempting to test a web service interface class using PHPUnit. Basically, this class makes calls to a SoapClient object. I am attempting to test this class in PHPUnit using the "getMockFromWsdl" method described here: http://www.phpunit.de/manual/current/en/test-doubles.html#test-doubles.stubbing-and-mocking-web-services However, since I want to test multiple methods from this same class, every time I setup the object, I also have to setup the mock WSDL SoapClient object. This is causing a fatal error to be thrown: Fatal error: Cannot redeclare class xxxx in C:\web\php5\PEAR\PHPUnit\Framework\TestCase.php(1227) : eval()'d code on line 15 How can I use the same mock object across multiple tests without having to regenerate it off the WSDL each time? That seems to be the problem.

• MySQL - getting SUM of MAX results from 2 tables

  - by SODA

  Hi, Here's my problem: I have 2 identical tables (past month data, current month data) - data_2010_03, data_2010_04: Content_type (VARCHAR), content_id (INT), month_count (INT), pubDate (DATETIME) Data in month_count is updated hourly, so for each combination of content_type and content_id we insert new row, where value of month_count is incrementally updated. Now I try something like this: SELECT MAX(t1.month_count) AS max_1, MAX(t2.month_count) AS max_2, SUM(max_1 + max_2) AS result, t1.content_type, t1.content_id FROM data_2010_03 AS t1 JOIN data_2010_04 AS t2 ON t1.content_type = t2.content_type AND t1.content_id = t2.content_id WHERE t2.pubDate < '2010-04-08' AND t1.content_type = 'video' GROUP BY t1.content_id ORDER BY result desc, max_1 desc, max_2 desc LIMIT 0,10 I get an error "Unknown column 'max_1' in 'field list'. Please help.

• What are some of best Javascript memory detecting tools?

  - by Philip Fourie

  Our team is faced with slow but serious Javascript memory leak. We have read up on the normal causes for memory leaks in Javascript (eg. closures and circular references). We tried to avoid those pitfalls in the code but it likely we still have unknown mistakes left in our code. I started my search for available tools but would like input from people with actual experience with these tools. Some of the tools I found so far (but have no idea how good and useful they would be for our problem): Sieve Drip JavaScript Memory Leak Detector Our search is not limited to free tools, it will be a bonus, but more importantly something that will get the job done. We do the following in our Javascript code: AJAX calls to a .NET WCF back-end that send back JSON data Manipulate the DOM Keep a fairly sized object model in the Javascript to store current state

• Implementing Role based Helpers

  - by Cynics

  So my question is how would you implement your handwritten Helpers based on the role of current user. Would it be efficient to change the behaviour at request time? e.g. the Helper somehow figures out the role of user, and include the proper SubModule? module ApplicationHelper module LoggedInHelper # Some functions end module GuestHelper # The Same functions end # If User is Guest then include GuestHelper # If User is LoggedIn then include LoggedInHelper end Is it efficient this way? is it rails way? I've got a whole bunch of function that act like this, and I don't want to wrap every single one of them in an if statement def menu_actions if current_user.nil? # User is guest { "Log in" => link_to "Login", "/login" } else # User is Logged In { "Log out" => link_to "Logout", "/logout" } end end Thank you for your time and thoughts.

• Wordpress auto excerpts from post content?

  - by Scott B

  I'm trying to create an auto generated post excerpt from the current page's post content using a function in my theme's header file. The post excerpt will be used as the page's meta description. Can someone give me an idea of how you might go about this once you've got the post content into a string variable? The somewhat tricky part is that, in order to predict a viable stopping point for the post excerpt, I'd like to specify that the cutoff point be the end of the first paragraph of text. And for that reason, it does not make sense to load the entire post content into the string I'm using. Can I grab the first paragraph without having to load the entire post content string? And I'm not certain how to test for that in php. Would regex be the only way?

• Object reference error even when object is not null

  - by Shrewd Demon

  hi, i have an application wherein i have incorporate a "Remember Me" feature for the login screen. I do this by creating a cookie when the user logs in for the first time, so next time when the user visits the site i get the cookie and load the user information. i have written the code for loading user information in a common class in the App_Code folder...and all my pages inherit from this class. code for loading the user info is as follows: public static void LoadUserDetails(string emailId) { UsersEnt currentUser = UsersBL.LoadUserInfo(emailId); if (currentUser != null) HttpContext.Current.Session["CurrentUser"] = currentUser; } Now the problem is i get an "Object reference" error when i try to store the currentUser object in the session variable (even though the currentUser object is not null). However the password property in the currentUser object is null. Am i getting the error because of this...or is there some other reason?? thank you

• How to detect when a tab is focused or not in Chrome with Javascript?

  - by LLer

  I need to know if the user is currently viewing the current tab or not in Google Chrome. I tried to use the events blur and focus binded to the window, but only the blur seems to be working. window.addEventListener('focus', function() { document.title = 'focused'; }); window.addEventListener('blur', function() { document.title = 'not focused'; }); The focus event works weird, only sometimes. If I switch to another tab and back, focus event won't activate. But if I click on the address bar and then back on the page, it will. Or if I switch to another program and then back to Chrome it will activate if the tab is currently focused.

• Mercurial: What is the benefit of fixing errors in earlier versions

  - by Ken Earley

  According to the guide, under the heading: Fixing errors in earlier revisions, it states this: When you find a bug in some earlier revision you have two options: either you can fix it in the current code, or you can go back in history and fix the code exactly where you did it, which creates a cleaner history. How does going back in history make it cleaner? It still makes a new changeset at tip. Does it have something to do with what is recorded as it's parent? Is there a way to view the logs seeing the newly inserted changeset in that order? This lesson is under the main heading of Lone developer with nonlinear history. Is this good practice when working on a team?

• Deploy maven generated site on Google Code svn?

  - by xamde

  Using a google code svn as a basic maven repository is easy. However, using mvn site:deploy efficiently on google code seems hard. So far, I found only these solutions: * Deploy to a local file:/// and use a PERL script to delete the old and copy the new * Use wagen-svn to deploy. This is very slow (hours!) and does not delete old files * Plus all mime-types are wrong I am looking for a solution that allows new developers in my projects to check out the current source and just use it, without requiring to install PERL or learn weird steps to perform or wait hours.

• NSFetchedResultsController doesn't fetch up the child-parent moc chain?

  - by Kronusdark

  I cannot find any clarification on this, so it may be a bug. Problem is, I have a series of parent-child Managed Object Context's. When I save on a child context the changes get pushed up to the parent, and I can fetch using a plain old NSFetchRequest. However, if I rely on an NSFetchedResultsController to pull these changes into a sibling context to the first, they do not see them. calling -(void)performFetch: error; doesn't seem to pull the changes either. After a restart of the app, all new data is available. My hypothesis is that NSFetchedResultsController only fetches from its current context and will not follow the chain to the persistent store. Can someone please set me straight here? Am I going to have to use notifications to monitor changes on other contexts? and finally, is this mentioned somewhere in the doc's? I cannot find it for the life of me.

• jQuery fadeIn IE Png Issue when loading from external

  - by Adam Stone

  I am loading data from external html files within my domain into a div on my webpage using a load content method in jQuery. I take the div out of the new page whilst hiding the div in the current page by fading this out and fading the new one in. There is a png image in both of these divs and it is creating horrid black blobs in IE, works fine in other browsers but due to IEs inability to process multiple filters its making a mess. I tried using the unit png fix to no avail, does anyone have any fixes or ideas to help keep my pngs looking nice during this transition? i46.tinypic.com/t9dtvr.jpg this is a screenshot of the problem, cheers also discovered that the png that is on the page originaly (before loading anything new) fades in and out perfectly using the unit png fix but stuff loading in and then back out from external files doesnt. Ive added the fix to those pages too but that doesnt work either.
