  • Can I use a local::lib if local::lib isn't installed globally and without eval-ing it in shell?

    - by xenoterracide
    I have a problem, I want to use local::lib; in a script. But because I need to use this script many places, I don't want to try adding the eval to bashrc, every time I install this script to a server. and I can't get local::lib installed globally (in the default @INC) on the servers. Is there any way I can use local::lib from within the script so that it knows where the module local::lib is without the eval that local::lib recommends and without installing it into a directory in the default @INC on the server?

  • Reverse engineering a custom data file

    - by kerchingo
    At my place of work we have a legacy document management system that for various reasons is now unsupported by the developers. I have been asked to look into extracting the documents contained in this system to eventually be imported into a new 3rd party system. From tracing and process monitoring I have determined that the document images (mainly tiff files) are stored in a number of 1.5GB files. These files seem to be read from a specific offset and then written to a tmp file that is then served via a web app to the client, and then deleted. I guess I am looking for suggestions as to how I can inspect these large files that contain the tiff images, and eventually extract and write them to individual files.

  • Is there any way to prevent the display of unmatched xml tags using xslt?

    - by StevenWilkins
    Here is a contrived example of an xml document. In my real world case, the xml is fairly complex with multiple nested levels. <alphabet> <a>A</a> <b>B</b> <c>C</c> ... and so on </alphabet> Using xslt, I want to transform the document so that only the vowels are printed. In my real world case, we're using empty template match tags to block the display. But that's too verbose for my liking.

  • Problem with Precision floating point operation in C

    - by Microkernel
    Hi Guys, For one of my course project I started implementing "Naive Bayesian classifier" in C. My project is to implement a document classifier application (especially Spam) using huge training data. Now I have problem implementing the algorithm because of the limitations in the C's datatype. ( Algorithm I am using is given here, http://en.wikipedia.org/wiki/Bayesian_spam_filtering ) PROBLEM STATEMENT: The algorithm involves taking each word in a document and calculating probability of it being spam word. If p1, p2 p3 .... pn are probabilities of word-1, 2, 3 ... n. The probability of doc being spam or not is calculated using Here, probability value can be very easily around 0.01. So even if I use datatype "double" my calculation will go for a toss. To confirm this I wrote a sample code given below. #define PROBABILITY_OF_UNLIKELY_SPAM_WORD (0.01) #define PROBABILITY_OF_MOSTLY_SPAM_WORD (0.99) int main() { int index; long double numerator = 1.0; long double denom1 = 1.0, denom2 = 1.0; long double doc_spam_prob; /* Simulating FEW unlikely spam words */ for(index = 0; index < 162; index++) { numerator = numerator*(long double)PROBABILITY_OF_UNLIKELY_SPAM_WORD; denom2 = denom2*(long double)PROBABILITY_OF_UNLIKELY_SPAM_WORD; denom1 = denom1*(long double)(1 - PROBABILITY_OF_UNLIKELY_SPAM_WORD); } /* Simulating lot of mostly definite spam words */ for (index = 0; index < 1000; index++) { numerator = numerator*(long double)PROBABILITY_OF_MOSTLY_SPAM_WORD; denom2 = denom2*(long double)PROBABILITY_OF_MOSTLY_SPAM_WORD; denom1 = denom1*(long double)(1- PROBABILITY_OF_MOSTLY_SPAM_WORD); } doc_spam_prob= (numerator/(denom1+denom2)); return 0; } I tried Float, double and even long double datatypes but still same problem. Hence, say in a 100K words document I am analyzing, if just 162 words are having 1% spam probability and remaining 99838 are conspicuously spam words, then still my app will say it as Not Spam doc because of Precision error (as numerator easily goes to ZERO)!!!. This is the first time I am hitting such issue. So how exactly should this problem be tackled?

  • How to programmatically click on a EIT Lightbox hyperling in asp.net

    - by CruelIO
    Hi On my webpage Im using EIT Lightbox to display images. I need to click on the Lightbox hyper link by code.

If I use the following code body.Attributes.Add("onload", "alert('popup');\n"); The alert is displayed Is there another way to do the click?

  • innerHTML yielding undefined, but correct data is visible

    - by Mike Dyer
    var Model,node; document.getElementById('sedans').innerHTML=''; var thismodelabbr,prevmodelabbr; for(var j=0; j<xmlDoc.getElementsByTagName('data').length; j++){ node = xmlDoc.getElementsByTagName('data')[j]; thismodelabbr=node.getAttribute('model'); if(prevmodelabbr!=thismodelabbr){ Model+='<a href="">'+ node.getAttribute('model')+'</a>'; } prevmodelabbr=thismodelabbr; document.getElementById('sedans').innerHTML=Model; } The above javascript snippet is working correctly and as needed, but I'm getting an "Undefined" response before the entry is displayed within its respective page. I'm assuming it has to do with the .innerHTML call. Any insight would be deeply appreciated.

  • jquery custom drag and drop

    - by samlochner
    I am trying to create functionality similar to drag and drop. I need to create my own as there will be some significant differences to the drag and drop in the jquery UI. I would like to have mousemove being called repeatedly at all times, and mousedown called every time the mouse is pressed. So I have the following code: $(document).bind('mousemove',function(e){ $("#coords").text("e.pageX: " + e.pageX + ", e.pageY: " + e.pageY); }); $(document).bind('mousedown',function(e){ }); ('coords' is the id of a div) As I move the mouse, coordinates are reported correctly in 'coords'. If I depress a mouse button and then move the mouse, coordinates are still reported correctly. But if I depress a mouse button on an image and then move the mouse, coordinates are reported correctly for a few sets, and then they seize up! Why is this happening and how can I fix it? Thanks, Sam

  • Doctrine 1.2 Column Naming Conventions for Many To Many Relationships

    - by Alan Storm
    I'm working with an existing database schema, and trying to setup two Doctrine models with a Many to Many relationship, as described in this document When creating tables from scratch, I have no trouble getting this working. However, the existing join tables use a different naming convention that what's described in the Doctrine document. Specifically Table 1 -------------------------------------------------- table_1_id ....other columns.... Table 2 -------------------------------------------------- table_2_id ....other columns.... Join Table -------------------------------------------------- fktable1_id fktable_2_id Basically, the previous developers prefaced all forign keys with an fk. From the examples I've seen and some brief experimenting with code, it appears that Doctrine 1.2 requires that the join table use the same column names as the tables it's joining in Is my assumption correct? If so, has the situation changed in Doctrine 2? If the answers to either of the above are true, how do you configure the models so that all the columns "line up"

  • How to improve performance of opening Microsoft Word when automated from c#?

    - by Abdullah BaMusa
    I have Microsoft Word template that I automated filling it’s fields from my application, and when the user request print I open this template. but creating word application every time user request print after filling fields is very expensive and lead to some delay while opening the template, so I choose to cache the reference to Word then just open the new filled template. that solve the performance issue as opening file is less expensive than recreating Word each time, but this work while the user just close the document not the entire Word application which when happened my reference to Word become invalid and return with exception says: “The RPC server is unavailable” next time request opening template . I tried to subscribe to BeforClosing event but his trigger for Quitting Word as well as Closing documents. My question is how to know if the word is closing document or quit the entire application so I take the proper action, or any hint for another direction of thinking about improve performance of opening word template.

  • Unique constraint with nullable column

    - by Álvaro G. Vicario
    I have a table that holds nested categories. I want to avoid duplicate names on same-level items (i.e., categories with same parent). I've come with this: CREATE TABLE `category` ( `category_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `category_name` varchar(100) NOT NULL, `parent_id` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`category_id`), UNIQUE KEY `category_name_UNIQUE` (`category_name`,`parent_id`), KEY `fk_category_category1` (`parent_id`,`category_id`), CONSTRAINT `fk_category_category1` FOREIGN KEY (`parent_id`) REFERENCES `category` (`category_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci Unluckily, category_name_UNIQUE does not enforce my rule for root level categories (those where parent_id is NULL). Is there a reasonable workaround?

  • Interface with inner implementation - good or bad

    - by dermoritz
    I am working on a project with many someInterface - someInterfaceImpl-pairs. Some days ago I got the idea (probably inspired by reading some objective c code) to include the default implementations as an inner class. Now some colleagues (all with much more java experience than me) saw this idea - feedback was between shocked and surprised ("this is working?"). I googled around a bit but didn't find much evidence of usefulness of this "pattern" (personal i like it): pdf-paper and a faq about code style What do you think - especially in those cases where an "default" implementation is tightly coupled to an interface. Update i just found this: Java Interface-Implementation Pair (see accepted answer)

  • Is it possible to supply the jQuery Validation plugin with a rules object?

    - by ethagnawl
    I took the rules that I'd been using to validate my form and broke them out into a JSON object, hoping to use the same set of rules for client/server validation. So, where I had: $(document.getElementById('new_listing_form')).validate({ rules: { apt: { required: true } } }); I'm attempting to use: var rules_obj = { apt: { required: true } }; $(document.getElementById('new_listing_form')).validate({ rules: rules_obj }); ... and the form is not being validated. Does anyone know if this is possible?

  • What color scheme do you use for programming?

    - by EndangeredMassa
    I get a lot of attention at work because I am the only one who bothered to change the default color settings in Visual Studio. I just modified them myself. I can provide the settings file if anyone cares to import it. Here's an example of how it looks. It reminds me of DOS/BASIC programming before I actually knew how to program. I also find it to be very readable. What color schemes do you use?! EDIT: To clarify, I only edited the text settings. The windows and panels of VS2005 are still the windows default.

  • How are managed the sequences by JPA and Hibernate?

    - by romaintaz
    Hi all, I am using Hibernate in my project, and many of my entities use a sequence for their technical keys. For example: @Entity @Table(name = "T_MYENTITY") @SequenceGenerator(name = "S_MYENTITY", sequenceName = "S_MYENTITY") public class MyEntity { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "S_MYENTITY") @Column(name = "MY_ENTITY_ID") private Long entityId; ... } I have two questions about the ID generated by Hibernate when a new object of this class is persisted: Why SequenceGenerator (from javax.persistence) has a default value of allocationSize set to 50 instead of 1? What are the interests of that? What is the default algorithm used by Hibernate to calculate the generated ID? It seems that Hibernate uses the value returned by the sequence hosted by my Oracle database, but then modify it before assigning it to my entity...

  • opening iWorks documents in iPad UIWebView

    - by user369156
    Hello, I'm writing an iPad application that has a UIWebView which I open word and excel documents in, but I want the user to be able to import those documents into the iWorks applications, Pages and Numbers, just like how you can do it in Safari if you open a document. If you open a document in Safari on the iPad, there'll be a button on the top bar that says "Open in..." and you can choose applications to open in. You get the top bar to appear by tapping on middle of the page. So is there an option you can set to allow UIWebView to show up the bar and automatically detect the content type and populate the list with applications you can import in? Or do I have to build this myself? And if I have to build my own, how do I open URLs to import documents into Pages and Numbers etc? Thanks, -David

  • remember passowrd works in ff but not in ie and chrome

  • Is there a way to ignore Cache errors in Django?

    - by Josh Smeaton
    I've just set our development Django site to use redis for a cache backend and it was all working fine. I brought down redis to see what would happen, and sure enough Django 404's due to cache backend behaviour. Either the Connection was refused, or various other errors. Is there any way to instruct Django to ignore Cache errors, and continue processing the normal way? It seems weird that caching is a performance optimization, but can bring down an entire site if it fails. I tried to write a wrapper around the backend like so: class CacheClass(redis_backend.CacheClass): """ Wraps the desired Cache, and falls back to global_settings default on init failure """ def __init__(self, server, params): try: super(CacheClass, self).__init__(server, params) except Exception: from django.core import cache as _ _.cache = _.get_cache('locmem://') But that won't work, since I'm trying to set the cache type in the call that sets the cache type. It's all a very big mess. So, is there any easy way to swallow cache errors? Or to set the default cache backend on failure?

  • Get content in iframe to use as much space as it needs

    - by Mark
    I'm trying to write a simple JavaScript based modal dialog. The JavaScript function takes the content, puts it in a new iframe and adds the iframe to the page. Works great so far, the only problem is that the content of the dialog (e.g. a table) gets wrapped, although plenty of space is available on the page. I'd like the content of the dialog, a table in my case, to use as much space as it needs, without wrapping any lines. I tried lots of combinations of setting width/style.width on the iframe and the table. Nothing did the trick. Here the code to show the iframe dialog: function SimpleDialog() { this.domElement = document.createElement('iframe'); this.domElement.setAttribute('style', 'border: 1px solid red; z-index: 201; position: absolute; top: 0px; left: 0px;'); this.showWithContent = function(content) { document.getElementsByTagName('body')[0].appendChild(this.domElement); this.domElement.contentDocument.body.appendChild(content); var contentBody = this.domElement.contentDocument.body; contentBody.style.padding = '0px'; contentBody.style.margin = '0px'; // Set the iframe size to the size of content. // However, content got wrapped already. this.domElement.style.height = content.offsetHeight + 'px'; this.domElement.style.width = content.offsetWidth + 'px'; this._centerOnScreen(); }; this._centerOnScreen = function() { this.domElement.style.left = window.pageXOffset + (window.innerWidth / 2) - (this.domElement.offsetWidth / 2) + 'px'; this.domElement.style.top = window.pageYOffset + (window.innerHeight / 2) - (this.domElement.offsetHeight / 2) + 'px'; }; } Here the test code: var table = document.createElement('table'); table.setAttribute('style', 'border: 1px solid black; width: 100%;'); table.innerHTML = "<tr><td style='font-size:40px;'>Hello world in big letters</td></tr><tr><td>second row</td></tr>"; var dialog = new SimpleDialog(); dialog.showWithContent(table); The table shows up nicely centered on the page, but the words in the first cell are wrapped to two lines. How do I get the table to use as much space as it needs (without using white-space: nowrap ;) Thanks in advance for any suggestions! -Mark

  • Universal control - simple question about dock and anchor

    - by Vytas999
    I use Visual Studio .NET to develop internal applications. I create a Windows control that will display custom status bar information. Different developers will use the control to display the same information in many different applications. The control must always be displayed at the bottom of the parent form in every application. It must always be as wide as the form. When the form is resized, the control should be resized and repositioned accordingly. How should I do that in the best way and why? A)Create a property to allow the developers to set the Dock property of the control. Set the default value of the property to AnchorStyle.Bottom. B) Create a property to allow the developer to set the Anchor property of the control. Set the default value of the property to AnchorStyle.Bottom.

  • How can I disable the F4 key from showing the items in a ComboBox

    - by Alex
    You might not know this, but pressing the F4 key on a ComboBox makes it's drop-down item list appear. I believe this is the default behavior on Windows. Does anyone know how to override this behavior in WPF (C#)? I know that overriding default behavior is generally seen as bad practice, however in this case I have a rugged-device that runs XP Embedded. It has a handful of prominent Function keys (F1-F6) that need to trigger different events. This works fine, however when focused over a ComboBox the events aren't triggered as the ComboBox drops down. I have tried catching the KeyDown event both on the form and on the ComboBox and listening for the F4 key, however it doesn't get this far as the key press must be handled at a lower level. Any ideas? Thanks.
