php selecting hash using wildcards

- by tipu

Say I have a hashmap, $hash = array('fox' => 'some value', 'fort' => 'some value 2', 'fork' => 'some value again); I am trying to accomplish an autocomplete feature. When the user types 'fo', I would like to retrieve, via ajax, the 3 keys from $hash. When the user types 'for', I would like to only retrieve the keys fort and fork. Is this possible? What I was thinking was using binary search to isolate the keys with 'f', instead of brute-force searching. Then continue eliminating the indexes as the user types out their query. Is there a more efficient solution to this?

Javas Math.sin() produces NaN all the time

- by milan1612

Forgive me if this is a dumb beginners problem, but I really don't get it. I have a member variable declared like so: public Double Value; When I assign 3.14159265 to Value and try to compute the sine of it, this happens: system.out.println(Value.toString()); //outputs 3.14159265 Value = Math.sin(Value); system.out.println(Value.toString()); //outputs NaN In fact, this happens with every single value I tried - even with 0! Math.sin() seems to always produce NaN as a result, regardless of the arguments value. The docs say: If the argument is NaN or an infinity, then the result is NaN. But my argument is clearly not NaN or infinity! What the heck is happening there?

Can I refresh a Yii CGridView from js?

- by Brian Dunn

When a "Create" modal dialog is submitted via XHR Then the rows in a Yii CGridView should be refreshed. I've tried to achieve this by rendering the new gridview in the XHR "create" action and then inserting it into the page via $("#list").html(response), but rendering a CGridView causes jQuery <script> include tags to be registered for inclusion, and so when I introduce those tags into the page they reload jQuery, which wipes out my live event handlers, so a bunch of stuff breaks. Which has me thinking, "the GridView knows how to refresh itself. heck, it does all the time on sort or page." So I can click a sort button in the GridView from js, but thats less than Ideal. I'd prefer to say $("#list").gridview('reload') or $.fn.gridview.reload("#list") or some such sense. Or do the way cool thing that is soo much simpler that you thought of just now.

ColdFusion structs Direct Assignment vs object literal notation.

- by Tom Hubbard

The newer versions of ColdFusion (I believe CF 8 and 9) allow you to create structs with object literal notation similar to JSON. My question is, are there specific benefits (execution efficiency maybe) to using object literal notation over individual assignments for data that is essentially static? For example: With individual assignments you would do something like this: var user = {}; user.Fname = "MyFirstnam"; user.Lname = "MyLastName"; user.titles = []; ArrayAppend(user.titles,'Mr'); ArrayAppend(user.titles,'Dr.'); Whereas with object literals you would do something like. var user = {Fname = "MyFirstnam", Lname = "MyLastName", titles = ['Mr','Dr']}; Now this limited example is admittedly simple, but if titles was an array of structures (Say an array of addresses), the literal notation becomes awkward to work with.

How to show an animated spinner while a background task is processing in nested rails model using aj

- by Globalkeith

My specific example is highly complex, so I will use the example shown by Ryan from Railscasts to discuss this: http://railscasts.com/episodes/197-nested-model-form-part-2 Background I have a form, let's say "Survey", which contains an arbitrary number of "Questions". Senario Give i am on the "Edit Survey" page. I would like to add a button to each "Question" field which calls a remote_function, which in turn queue's up a delayed_job to execute some processing on the "Question". To give feedback to the user, i would like to disable the button, and show an animated spinner, which remains until the delayed_job has processed the "Question". Hint - I can add methods to the "Question" model to indicate the status of the delayed_job. So, with best practices in mind, what is the best way to achieve this?

getjson jquery parsing an array

- by Ozaki

TLDR: Want to get each heading from an array and insert it into a div without knowing what is inside the div using Jquery - getJSON. I have JSON array lets say: jsonfeed({ "items": [ { "d":{"title":"034324324-22344231-10"} }, { "d"{"title":"23423404-3423422-10"} }, { "d"{"title":"0234234324-32432422-10"} }, { "d"{"title":"0234234324-223534534-10"} ] }) And I want to parse it as for each "title" to insert it into a div. Trying along the lines of $.getJSON(url, function(data){ $.each(data.items, function(i,item){ $('#testfield').html('<p>' + item.d.title + '</p>'); }); }); to no avail. I am using Getjson in other places but in cases where I know what request I am making. e.g: $('#livetime').html(data.Time); Which is all working perfectly fine but in this case I need to get the details out of the array without knowing what is inside the array I'm sure there is something simple that I'm missing here or doing wrong ^^.

How to pass a string containing both single and double quotes as a parameter to XSLT in PHP?

- by Boaz

Hi, I have a simple PHP-based XSLT trasform code that looks like that: $xsl = new XSLTProcessor(); $xsl->registerPHPFunctions(); $xsl->setParameter("","searchterms", $searchterms); $xsl->importStylesheet($xslDoc); echo $xsl->transformToXML($doc); The code passes the variable $searchterms, which contains a string, as a parameter to the XSLT style sheet which in turns uses it as a text: <title>search feed for <xsl:value-of select="$searchterms"/></title> This works fine until you try to pass a string with mixes in it, say: $searchterms = '"some"'." text's quotes are mixed." In that point the XSLT processor screams: Cannot create XPath expression (string contains both quote and double-quotes) What is the correct way to safely pass arbitrary strings as input to XSLT? Note that these strings will be used as a text value in the resulting XML and not as an XPATH paramater. Thanks, Boaz

Scrolling png with text & alpha on top of a static UIImageView

- by heymon

I have a view controller that has a view structure as follows: FilesOwner FirstResponder View ImageView (.jpg) ScrollView ImageView (.png) The text in the innermost imageview has white text and clear (alpha) all around. I want to scroll the innermost imageview, and see the background image (the .jpg) behind it. Its not working. Its acting like the scrollview background obscures the underneath .jpg. I say this because if I change the background color of the scrollview, that's what I see i.e. if I set it black, I see black behind my .png, if I set it white, I see white. If I change the alpha of the scrollview that doesn't seem to work either. The one other thing I tried was unchecking drawing: Opaque, but that doesn't get it either.

searching for address matches using sql server 2008 full text search

- by Sridhar

Hi, I am not sure how to search for address matches using sql server 2008 full text search. This is what I tried but it doesn't return any records. TableA ------ Address1 Address2 City State Zip All the above columns in the table are full text indexed. Let's say if the user enters "123 Apple street FL 33647" and I have a record in the table as Address1 = "123" , Address2 = "Apple street", City = "Tampa", State = "FL" and Zip = "33647" I would like the query to return this. can you please let me know how I would do this. query tried -------------- SELECT * FROM TableA WHERE CONTAINS((Address1, Address2, City, State, zip), N'FORMSOF(THESAURUS, 123AppleStreetFL33647)'); If I put spaces in the search word, it is giving syntax error. Thanks, sridhar.

Perl 'system' failure messages

- by mmccoo

Say I have this perl "program" called simple.pl: #!/usr/bin/perl use xyz; # xyz is bogus and doesn't exist And I also have this "program", called simple2.pl: #!/usr/bin/perl system("simple.pl"); my $abc = `simple2.pl`; printf("abc %s\n", $abc); for both system and backtick, I get this message: Can't exec "simple.pl": No such file or directory at scripts/perl/simple2.pl line 7. Can't exec "simple2.pl": No such file or directory at scripts/perl/simple2.pl line 9. Not very useful for the user calling simple2.pl. Is there a way to get a more useful message?

Which offer to pick?

- by Shawn

OK. This is kinda silly, but I'd really like to hear what you guys say. Here is the thing: I used to be an php developer and started looking for jobs 3 weeks ago and now I got 2 offers at hand. If I took the first one what I do would be 100% in PHP - simply dev works on a ecommerce project. If I go with the second one, the projects would be in python which I didn't have too much experiences on and is kinda exited about the new stuff I'm going to learn. But wait, the first offer gives more money(1k plus) and that's why I'm still hesitating and troubling you guys.) If you were me, which one would you pick? I know there could be other factors to be considered like 'which position is closer to your home so you could take good care of your dog', well let's forget about those things for now.

Haskell Console IO in notepad++

- by IVlad

I've recently started to learn Haskell. I have this code module Main where import IO main = do hSetBuffering stdin LineBuffering putStrLn "Please enter your name: " name <- getLine putStrLn ("Hello, " ++ name ++ ", how are you?") I'm using the GHC compiler together with the notepad++ editor. The problem is the interaction goes like this: Process started Vlad Please enter your name: Hello, Vlad, how are you? <<< Process finished. As you can see, output is only written after I input something. This was a bit unexpected, as I was sure the program would first ask for my name, then I'd get to enter it and then it would say hello. Well, that's exactly what happens if I run the exe manually, yet not if I run it with notepad++ and use its console wrapper... How can I make notepad++ display the output when it should, and not all of it just before the program terminates? Is this even possible?

SQL: Gather right hand values from a join

- by Max Williams

Let's say a question has many tags, via a join table called taggings. I do a join thus: SELECT DISTINCT `questions`.id FROM `questions` LEFT OUTER JOIN `taggings` ON `taggings`.taggable_id = `questions`.id LEFT OUTER JOIN `tags` ON `tags`.id = `taggings`.tag_id I want to order the results according to a particular tag name, eg 'piano', so that piano is at the top, then by all the other tags in alphabetical order. Currently i'm using this order clause: ORDER BY (tags.name = 'piano') desc, tags.name Which is going completely wrong - the first results i get back aren't even tagged with 'piano' at all. I think my problem is that i need to group the tag names somehow and do my ordering test against that: i think that doing it against the straight tags.name isn't working due to the structure of the resultant join table (it does work if i just do a simple select on the tags table) but i can't get my head around how to fix it. grateful for any advice, max

Magento Checkout options

- by graham barnes

Hi I want to add some options to my magento, lets say i print on clothing, a customer buys some t-shirts, shirts and jackets from me, it totals to £60+ VAT on the checkout area where i signup and not before I need to add an option where I can add a text box and upload option, can i do this? I ideally then want to add some pricing options if the user has chosen to add some branding to a product or multiple products e.g. if the branding was on the top right of the shirt it will cost £5.00, if on the back it costs £7.00 etc all if possible to be done via the admincp. I also want an option so when they upload their logo for the first time they are charged a one off charge, like a setup fee but If the customer has allready sent in there logo then no charge applies. thanks Graham

How to use CFUUID, can CFUUID be traced back to a unique individual. security/privacy

- by Kevin

Hi, i an new to iphone Dev and the concept of CFUUID, so thought i should ask, before i start implementing it. so the string returned by CFUUID is it really unique or can it be traced back to a unique individual. meaning lets say, i generate a CFUUID object and convert it to string(using the methods provided) , and then this info is used in my app or stored on a server database. and how unique is it, i mean is their a chance it can be similar to one generated on some other device. is it a good idea to use this info freely or are their some security/privacy aspects that i am not thinking about here. any help is greatly appreciated thanks

struts2 StringLengthFieldValidator annotation not working for empty string

- by dcp

Let's say I have this annotation for a struts2 validation: @StringLengthFieldValidator(key = "key14", fieldName = "poNumber", minLength = "1", maxLength = "255", message = "poNumber must be between 1 and 255 characters.") public void setPoNumber(String poNumber) { this.poNumber = poNumber; } The behavior I'm seeing is that if I pass a string that is empty to this setter, (ex. setPoNumber("")) the validator doesn't catch the error. Strings that are over 255 are caught fine. Equally strange is if I change minLength to 2 and pass a string of length 1, it will catch the error as well. But empty string does not seem to be caught when minLength = "1". For this reason, I cannot use this validator. I just wondered if I'm doing something wrong. I'm using struts 2.1.8.1. Thanks for any advice.

Are ORM's counterproductive to OO design?

- by Jeremiah

In OOD, design of an object is said to be characterized by its identity and behavior. Having used OR/M's in the past, the primary purpose, in my opinion, revolves around the ability to store/retrieve data. That is to say, OR/M objects are not design by behavior, but rather data (i.e. database tables). Case and point: Many OR/M tools come with a point-to-a-database-table-and-click-object-generator. If objects are no longer characterized by behavior this will, in my opinion, muddy the identity and responsibility of the objects. Subsequently, if objects are not defined by a responsibility this could lend a hand to having tightly coupled classes and overall poor design. Furthermore, I would think that in an application setting, you would be heading towards scalability issues. So, my question is, do you think that ORM's are counterproductive to OO design? Perhaps the underlying question would be whether or not they are counterproductive to application development.

Hope I have made my question clear. Any guidance would be highly appreciated. Thanks.

Why does Java read its default settings from the system

- by Bozho

Java is reading the locale, timezone and encoding information (and perhaps more) from the system it is installed on. This often brings bad surprises (brought me one just yesterday). Say your development and production servers are set to have TimeZone GMT+2. Then you deploy on a production server set to GMT. a 2-hour shift may not be easy to observe immediately. And although you can pass a TimeZone to your calendars, APIs might be instantiating calendars (or dates) using the default timezone. Now, I know one should be careful with these settings, but are easy to miss, hence make programs more error-prone. So, why doesn't Java have its own defaults - UTF-8, GMT, en_US (yes, I'm on non-en_US locale, but having it as default is fine). Applications could read the system settings via some API, if needed. Thus programs would be more predictable. So, what is the reason behind this decision?

asp.net client/browser url

- by Marcus King

I'm wondering how I can get the url from the browser in asp.net. I have a page that I use globalization/localization for and I am redirecting (via server not code) from www.spanishversion.com to www.englishversion.com but the url is masked to still say www.spanishversion.com. I want to get what the browser's url is but when I try things like Request.Url.ToString() Request.Url.OriginalUrl Request.Path Request.RawUrl Request.ServerVariables["SERVER_NAME"] it always comes back as www.englishversion.com. Is there a way that I can explicitly read the url from the browser? Thanks.

Teaching coworkers LINQ...

- by cyberzed

I have set myself upon a journey to educate my coworkers (all have accepted my mission, even the boss). Every day I seem to find a piece of code that could have been less error prone if my coworkers knew more about the framework, better-know-framework (in courtesy of DNR ;)) is part two of my teaching process. First part is teaching my coworkers about LINQ, what it can do for them and how it is written. My big question is where are all the good basic resources for LINQ education, everything if find is tightly coupled to Linq2Sql or all other sorts of material. Neither have I been able to find a tutorial for the actual linq syntax (except a specification of it all). (I hope this haven't been asked before but if it has please say so, cause then my searching skills have failed ;) )
