• Jquery taconite selector with character that needs to be escaped

  - by hdx

  I'm using the jquery taconite plugin to make an ajax request that will replace a certain element in my page, however the element has an id like "email.subject".. I can select it just fine if I do '$("email\\.subject")', but when I try to use the taconite plugin like this: <taconite> <replaceWith select="#email\\.subject"> JUCA </replaceWith> </taconite> The plugin log says: [taconite] No matching targets for selector: #email\\.subject How can I make this work?

• How can I consolidate deferred/delayed calls in Objective-C ?

  - by thrusty

  I'd like to ensure that certain maintenance tasks are executed "eventually". For example, after I detect that some resources might no longer be used in a cache, I might call: [self performSelector:@selector(cleanupCache) withObject:nil afterDelay:0.5]; However, there might be numerous places where I detect this, and I don't want to be calling cleanupCache continuously. I'd like to consolidate multiple calls to cleanupCache so that we only periodically get ONE call to cleanupCache. Here's what I've come up with do to this-- is this the best way? [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(cleanupCache) object:nil]; [self performSelector:@selector(cleanupCache) withObject:nil afterDelay:0.5];

• Linux friendly (.NET/Mono) browser object?

  - by HankB

  Hi folks, A friend of mine (familiar with C# and .NET on Windows) has asked how to port some functionality to a Linux host. This functionality is based on a JSP web page that fetches some data from the host server and displays it in a banner on a page. His Win/C#/.NET code simply creates a browser object which loads the page and he then inspects the resulting object to extract the data. I'm wondering what alternatives exist to duplicate this function on Ubuntu Linux. I'm not certain that the necessary libraries exist on this installation. I can assume that things like Perl and Python are ubiquitous, but I am not familiar with any libraries that include a browser object capable of executing javascript and exposing the results to another program. Any suggestions that lead in this direction are welcome. Thanks!

• HTML: How to get a child element to show behind (lower z-index) than its parent

  - by dclowd9901

  I need for a certain dynamic element to always appear on top of another element, no matter what order in the DOM tree they are. Is this possible? I've tried z-index (with position: relative), and it doesn't seem to work. I hate to be vague, but this is the simplest way I can think of asking this question without explaining its purpose ad nauseum. So, to recap, I need <div class="a"> <div class="b"></div> </div> <div class="b"> <div class="a"></div> </div> To display exactly the same when rendered. And for flexibility purposes (I'm planning on distributing a plugin that needs this functionality), I'd really like to not have to resort to absolute or fixed positioning.

• How created method with signature as List

  - by London

  Hi all, I'm very new to Java programming language so this is probably dumb question but I have to ask it because I can't figure it out on my own. Here is the deal. I want to create method which extracts certain object type from a list. So the method should receive List as argument, meaning list should contain either Object1 or Object2. I've tried like this : public Object1 extractObject(List<?>){ //some pseudo-code ... loop trough list and check if list item is instance of object one return that instance } The problem with declaring method with List<?> as method argument is that I receive compilation error from eclipse Syntax error on token ">", VariableDeclaratorId expected after this token. How do I set the method signature properly to accept object types either Object1 or Object2 ? Thank you

• Pro's and Con's of unit testing after the fact.

  - by scope-creep

  I have a largish complex app around 27k lines. Its essentially a rule drive multithreaded processing engine, without giving too much away Its been partially tested as it's been built, certain components. Question I have, is what is the pro's and con's of doing unit testing on after the fact, so to speak, after its been implemented. It is clear that traditional testing is going to take 2-3+ months to test every facet, and it all needs to work, and that time is not available really. I've done a fair bit of unit testing in the past, but generally it's been on desktop automation or LOB apps, which are fairly simple. The app is itself is highly componentized internally, interface driven really. I've not decided on what particular framework to use. Any advice would be appreciated. What say you.

• need to query MongoDB using php

  - by Mario Villarroel

  I need to query mongodb with something like this: ("something" < X OR "something" = "nll") AND ("someother"X OR "someother"= "nll") AND z=$z AND s=1 I've tried a few things, but can't get it to work, this is what I've tried: find( array( '$or'=array(array("something"=array("$le",$X)),array("something"="nll")), '$or'=array(array("someother"=array("$ge",$X)),array("someother"="nll")) )) But that's getting me the OR overwritten, so I'm lost on that... After diggin a bit more, I assembled this code that seems to be what I need, but doesn't work either: find( array('$and'=array( array( '$or' = array( array("something"=array('$gte'=$X)),array("something"="nll"))), array('$or' = array( array("someother"=array('$lte'=$X)),array("someother"="nll")))),"Z"=$z, "s"="1"); But this doesn't work as it returns zero results and I know for sure that there are more than 2 items that match on the db. (100% certain)

• Flex: How can I use the @ContextRoot in a Button or LinkButton

  - by Dave Meurer

  I'm trying to create a button that will simply link back to the context root. I noticed flex has a @ContextRoot attribute that appears to work only in certain cases. For example, if I try to use it in the following mxml: <mx:Button label="Back to Root" click="navigateToURL(new URLRequest(@ContextRoot()), '_parent')"/> I get the following error: Error: Attributes are not callable. I can't seem to find this technique explained anywhere, is there another way? Thanks for the help! Dave

• Use filter(), but work with both results

  - by Tomalak

  In jQuery, filter() reduces your result to those elements that fulfill a certain condition. This splits the list in two parts. Working with the "good half" of the elements is easy: $("some selector").filter(function() { // determine result... return result; }).each( /* do something */ ); But how can I work with the "other half" of my elements, too - but without doing the equivalent of this: $("some selector").filter(function() { // determine result... return !result; }).each( /* do something else */ ); Basically, I'd like to feed two separate /* do something */ parts to a single filter. One for those that match, and one for the others - without having to filter twice. Am I missing a jQuery function that does this? P.S.: I guess I could do: $("some selector").each(function() { // determine result... if (result) /* do something */ else /* do something else */ }); But I was hoping for something nicer.

• For what purpose does java have a float primitive type?

  - by Roman

  I heard plenty times different claims about float type in java. The most popular issues typicaly regard to converting float value to double and vice versa. I read (rather long time ago and not sure that it's actual now with new JVM) that float gives much worse performance then double. And it's also not recommended to use float in scientific applications which should have certain accuracy. I also remember that when I worked with AWT and Swing I had some problems with using float or double (like using Point2D.Float or Point2D.Double). So, I see only 2 advantages of float over double: it needs only 4 bytes while double needs 8 bytes JMM garantees that assignment operation is atomic with float variables while it's not atomic with double's. Are there any other cases where float is better then double? Do you use float's in your applications? It seems to me that the only valuable reason java has float is backward compatibility.

• Typical text encoding and EOL behavior on mobile devices

  - by Dan W

  Typical things to worry about when dealing with text are the BOM/signature, encoding, and the end of line (EOL) char/chars. I know that Windows often favours \r\n (CR+LF) and Mac/Linux favours \n (LF), but how about popular mobile devices such as the iPhone and Android? Do typical apps on those platforms favour one or the other (or maybe even \r for iOS)? I'll supply both types to the user just in case, but I'd like to choose one as default. Also, which text encodings are mobiles most likely to use - UTF-8, iso-8859-1, Windows 1252 (or other default codepage) or maybe even UTF-16? And if they use UTF-8/16, are they likely to need (or require not having) a BOM/signature? What is the typical behavior here? Once again, I'll supply a range of encodings to the user just in case, but I'd like to prioritize or use certain encodings as default if it's appropriate.

• Determine IP# of domain from client browser

  - by Tim W.

  Greetings all, I would very much like to determine the IP# of a domain from client script. It's for use in a testing application to determine whether or not a certain domain is set to a QA address as opposed to the address live on the . The testing machine will have it's host file set to resolve a domain to the QA address. Pinging from the server won't help since the server is getting the public DNS address. Is this possible in JavaScript? Maybe a Flash could do the trick?

• MediaElement seems to disable lock screen when playing a video

  - by CrossProduct

  I am working on an application that plays a video using the MediaElement component. Now, I would like that if the user is idle, the lock screen appears, as configured by the user in the Settings of the device. If I don't play a video, the lock screen indeed appears. But, when a video is playing no lock screen appears. I cannot find any information on this. Currently I set the idle detection modes like this: PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled; PhoneApplicationService.Current.UserIdleDetectionMode = IdleDetectionMode.Enabled; I am a bit lost now. The only solution I can think of is running a timer myself and stop the video playback after a certain time. (but there seems to be no API calls to receive the configured lock timeout.) Any suggestions are welcome, thanks.

• replacing text within quotes until next quote

  - by Jordan Trainor

  String input = "helloj\"iojgeio\r\ngsk\\"jopri\"gj\r\negjoijisgoe\"joijsofeij\"\"\"ojgsoij\""; This is my current code that works but iv added some code that has to run before this which makes some '"' split onto another line thus making the code below obsolute unless under certain cirumstances the '"' is not put onto the next line. firstQuote = input.IndexOf("\""); lastQuote = input.LastIndexOf("\""); input = input.Substring(0, firstQuote) + "<span>quote" + input.Substring(firstQuote + 1, lastQuote - (firstQuote + 1) + "quote</span>" + input.Substring(lastQuote + 1, lines.Length - (lastQuote + 1); How could I change the input string from input = "helloj\"iojgeio\r\ngsk\\"jopri\"gj\r\negjoijisgoe\"joijsofeij\"\"\"ojgsoij\""; to input = "helloj(<span>quoteiojgeio\r\ngsk\\"jopriquote</span>gj\r\negjoijisgoe<span>quotejoijsofeijquote</span>quote<span>quote</span>ojgsoij<span>quote</span>";

• Wizard based feature install in sharepoint 2007?

  - by JL

  I have a feature that gets installed using a WSP package, when the feature is activated, I would like the following to happen: The feature will contain a list definition. When the feature gets activated by an end user (the user physically clicks the feature activation button in site features admin) - I would like a modal dialog to appear then ask the user to provide some additional details. 3.1 The additional details will be supplying a certain number of names. For example Mary, John, Peter. Form logistics I can handle. Once the form is complete that information needs to somehow get back to the feature reciever, so that I can then take the base list definition, and use it as a template to create list instances for all the names supplied - so if user had supplied Mary and Peter, then 2 list instances will be created when this feature is activated. Is any of this possible with MOSS 2007? Thank you

• Automating site interaction

  - by Leocer

  I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.

• What's the standard behaviour for an out parameter when a TryXxxx method returns false?

  - by Matt Lacey

  Assuming a method with the following signature bool TryXxxx(object something, out int toReturn) What is it acceptable for toReturn to be if TryXxxx returns false? In that it's infered that toReturn should never be used if TryXxxx fails does it matter? If toReturn was a nulable type, then it would make sense to return null. But int isn't nullable and I don't want to have to force it to be. If toReturn is always a certain value if TryXxxx fails we risk having the position where 2 values could be considered to indicate the same thing. I can see this leading to potential possible confusion if the 'default' value was returned as a valid response (when TryXxxx returns true). From an implementation point if view it looks like having toReturn be a[ny] value is easiest, but is there anything more important to consider?

• g++ - is using the "-g" flag for production builds a good idea?

  - by Grigory

  Just to give some context, I'm talking about compiling C++ code with g++ here. I can see how including the -g flag for production builds would be convenient for maintenance: the program will be much easier to debug if it crashes unexpectedly. My question here is, does including the -g flag affect the output executable in any other way than increasing its size? Can it somehow make the code slower (e.g. by turning off certain optimizations)? From what I understand, it shouldn't (the documentation only mentions the inclusion of debug symbols), but I'm not sure.

• Hibernate criteria with projection not performing query for @OneToMany mapping

  - by Josh

  I have a domain object, Expense, that has a field called initialFields. It's annotated as so: @OneToMany(fetch = FetchType.EAGER, cascade = { CascadeType.ALL }, orphanRemoval = true) @JoinTable(blah blah) private final List<Field> initialFields; Now I'm trying to use Projections in order to only pull certain fields for performance reasons, but when doing so the initialFields field is always null. It's the only OneToMany field and the only field I am trying to retrieve with the projection that is behaving this way. If I use a regular HQL query initialFields is populated appropriately, but of course I can't limit the fields. Anyone ever seen anything like this?

• Loading a DB table into nested dictionaries in Python

  - by Hossein

  Hi, I have a table in MySql DB which I want to load it to a dictionary in python. the table columns is as follows: id,url,tag,tagCount tagCount is the number of times that a tag has been repeated for a certain url. So in that case I need a nested dictionary, in other words a dictionary of dictionary, to load this table. Because each url have several tags for which there are different tagCounts.the code that I used is this:( the whole table is about 22,000 records ) cursor.execute( ''' SELECT url,tag,tagCount FROM wtp ''') urlTagCount = cursor.fetchall() d = defaultdict(defaultdict) for url,tag,tagCount in urlTagCount: d[url][tag]=tagCount print d first of all I want to know if this is correct.. and if it is why it takes so much time? Is there any faster solutions? I am loading this table into memory to have fast access to get rid of the hassle of slow database operations, but with this slow speed it has become a bottleneck itself, it is even much slower than DB access. and anyone help? thanks

• is this a correct way to generate rsa keys?

• Java library to partially export a database while respecting referential integrity constraints

  - by Mwanji Ezana

  My production database is several GB's uncompressed and it's getting to be a pain to download and run locally when trying to reproduce a bug or test a feature with real data. I would like to be able to select the specific records that interest me, then have the library figure out what other records are necessary to produce a dataset that respects the databases integrity constraints and finally print it out as a list of insert statements or dump that I can restore. For example: given Author, Blog and Comment tables when I select comments posted after a certain date I should get inserts for the Blog records the comments have foreign keys to and the Author records those Blogs have foreign keys to.
