  • How do you use jQuery .data() to store html?

    - by Al
    Hi all - when I look up the syntax for .data(), it gives examples like this: $('body').data('foo', 52); I am doing AJAX loads and I was wondering if it is possible to store the incoming html using .data() so once the content is loaded, I would not need to do another AJAX load if the same link is clicked again - I would check to see if the .data key is empty. Would something like this work?: To load the contents of a #ajaxdiv into storage: $('body').data('storage', div#ajaxdiv.html()); To test if the data has already been loaded: if $('body').data('storage') != '' { div#ajaxdiv.html($('body').data('storage')); } Thanks in advance!!

  • Why use hashing to create pathnames for large collections of files?

    - by Stephen
    Hi, I noticed a number of cases where an application or database stored collections of files/blobs using a has to determine the path and filename. I believe the intended outcome is a situation where the path never gets too deep, or the folders ever get too full - too many files (or folders) in a folder making for slower access. EDIT: Examples are often Digital libraries or repositories, though the simplest example I can think of (that can be installed in about 30s) is the Zotero document/citation database. Why do this? EDIT: thanks Mat for the answer - does this technique of using a hash to create a file path have a name? Is it a pattern? I'd like to read more, but have failed to find anything in the ACM Digital Library

  • Creating a Mac OS application that interacts with all text fields

    - by mjdth
    What would be the first step to creating an application for Mac OS X that would take user interaction from any text field in the system? A couple examples of apps that do this are TextExpander and Typinator. What I want to do would be using similar functions to access Text fields throughout the computer during user input to give other additional options, I'm just not sure where to even start in Xcode and with what type of project to use. Any help or links would be greatly appreciated! Thanks!

  • access custom group

    - by Carlos
    I have my Access 2007 database configured to use "Custom" groups in the navigation pane. I've grouped all my tables in a way that makes sense. However, whenever I update a link table, it loses its grouping. I have not been able to find a way to avoid this. Since it seems to be unavoidable, I'd like to simply have a macro that adds the table back to the right group programatically. I have not found any examples on how to do this. Any suggestions?

  • jQuery UI sortable on select options

    - by user1038814
    I'm trying to get jQuery UI default sortable to work on options in a select multi list box but can't seem to get it working. Can this work with a select option? I've only seen examples with <li> everywhere. Here's my JavaScript: $(function() { $( "#secondSelectms2side__dx" ).sortable(); $( "#secondSelectms2side__dx" ).disableSelection(); }); And the HTML: <select title="" name="secondSelectms2side__dx" id="secondSelectms2side__dx" size="8" multiple="multiple"> <option value="4">asdsdsds</option> <option value="10">bsdsdsdsd</option> <option value="2">csdsdsds</option> </select>? My code is on jsFiddle: http://jsfiddle.net/noscirre/DRUPe/

  • Sockets: RAW or STREAM

    - by user1415536
    May be the question is a bit stupid, but I'll ask it. I read a lot about raw sockets in network, have seen several examples. So, basically with raw sockets it's possible to build own stack of headers, like stack = IP + TCP/UDP + OWN_HEADER. My question is, is it possible to get some kind of ready frame of first two(IP + TCP/UDP) from the linux kernel and then just append own header to them? The operating system in question is linux and the language is C. I cannot find any function which can do such a thing, but may be I'm digging in a wrong direction.

  • Learning to use open source software [closed]

    - by dole
    Do you know any book, blog, tutorial which explains in a detailed way the use of some open source projects? Maybe you have written such a tutorial, example of open source libraries, and your final product is great for a beginner to understand it. I'm in the learning stage of OOP and I really need to learn by examples. I'll like to find some text which explains the use of some open source software/libraries and the good practices. Beign honestly I feel scared to use the open source libraries as I wish/think at this moment. I feel like as I still write procedural code and not OOP. Do you know such tutorials, links, blogs, stories, pages? PS: I know C and PHP. I can't say that I know C++ yet, and that's why I need your help.

  • Delphi Search files and directories fastest alghorithm

    - by radu-barbu
    Hi, I'm using Delphi7 and i need a solution to a big problem.Can someone provide me a faster way for searching through files and folders than using findnext and findfirst? because i also process the data for each file/folder (creation date/author/size/etc) and it takes a lot of time...I've searched a lot under WinApi but probably I haven't see the best function in order to accomplish this. All the examples which I've found made in Delphi are using findfirst and findnext... Also, I don't want to buy components or use some free ones... Thanks in advance!

  • Does CLOS have an eql specialization dispatch on strings?

    - by mhb
    Examples of what you can do. (defmethod some-fn ((num real)) (print "an integer")) (defmethod some-fn ((num real)) (print "a real")) (defmethod some-fn ((num (eql 0))) (print "zero")) (some-fn 19323923198319) "an integer" (some-fn 19323923198319.3) "a real" (some-fn 0) "zero" It also works with a general 'string type. (defmethod some-fn ((num string)) (print "a string")) (some-fn "asrt") "a string" Not with a specific string, however (defmethod some-fn ((num (eql "A")) (print "a specifict string"))) => doesn't compile I imagine it doesn't work because eql does not work on strings in the way that would be necessary for it to work. (eql "a" "a") => nil Is there a way to do it?

  • In datastore, confused on how to pass a list of key_names as an argument to somemodel.get_or_insert(

    - by indiehacker
    Are there examples of how to pass a list of key_names to Model.get_or_insert() ? My Problem: With a method of ParentLayer I want to make the children. The key_names of the new (or editable) entities of class Child will come from such a list below: namesList = ["picture1","picture2"] so I should be able to build a list of key_names with method from the parent class as follows: class ParentLayer(db.Model): def getOrMakeChildren(self, namesList): keyslist = [ db.Key.from_path( 'Child' , name , parent = self.key() ) for name in namesList ] the problem is next where I simply want to get_or_insert entities based on keylist defined above: childrenEntitiesList = Child.get_or_insert(keyslist) # no works? also none of the below attempts worked: #childrenEntitiesList = Child.get_or_insert(keyslist, parent = u'TEST') #childrenEntitiesList = Child.get_or_insert(keyslist, parent=self.key().name() ) #childrenEntitiesList = Child.get_or_insert(keyslist, parent=self.key()

  • Building FFmpeg for Android

    - by varevarao
    I've spent almost a week on this now, trying to get FFmpeg "Angel" to build for Android. I've tried build scripts from all over the internet to no avail. I got closest was using this. A sthe author himself says the script doesn't work for newer versions of FFmpeg due to this bug, which has been dismissed on that ticket saying "I found a Makefile that does it." This was dis-heartening, being the only post on all of the cast Google world that was anywhere close to my problem. So, question time: Is there a way to get around the above bug? I'm trying to use the newest ffmpeg API, and "Love" is just giving me "undefined reference" errors while trying to use av_encode_video2(), and av_free_frame(). The code I was working on the lines of is at the ffmpeg git repo, under /doc/examples/decoding_encoding.c (the function starting on line 338)

  • Is there a way to implement an XMPP client or message reciever that can recieve all the messages fro

    - by roberto
    Basically im trying to build a bot that can send a message using one of many accounts out to a user and be able to receive messages to that account it originally used process and do whatever I need it to do. So far I found the JAXL library (http://code.google.com/p/jaxl/) but based on examples it is only able to handle one user at a time. Any suggestions or ideas? thank you in advanced. btw if there is anyway to make the server automatically forward those messages to another program or whatever that works just as well.

  • What are the best blogs for staying up to date on C#, ASP.NET, LINQ, SQL, C++, Ruby, Java, Python?

    - by Arj
    Apologies if this repeats another - but I couldn't fine one like it. My day to day programming spans a fair number of technologies: C#, ASP.NET, LINQ / SQL, C++, Ruby, Java, Python in approximately that order. It's a struggle to keep up to date on any of best practices, new ideas, innovation and improvements, let alone all. Therefore, what would your top 1 blog be in each of these technologies and which technology do you find easiest to stay up to date with? I'd have a bias towards blogs with broad and high level rather than narrow and detailed content / solutions / examples.

  • Is it possible to reference object within the same object?

    - by fudgey
    I've been messing around with jQuery plugin code and I'm trying to put all of my common variables into a single object for easy access. I have included a few examples below on how I've done this, but I'm wondering how others deal with this problem. Lets say I have this var x = function(options){ var defaults = { ulist : $('ul#list'), listLen : $('ul#list').children().length } $.extend(options, defaults); // do other stuff } What I'm trying to do is use the ulist object in as a base, then find the number of li's I guess I could do this: var x = function(options){ var defaults = { ulist : $('ul#list'), listLen : 0 } defaults.listLen = defaults.ulist.children().length; $.extend(options, defaults); // do other stuff } or this: var x = function(options){ var defaults = { ulist : $('ul#list') }; var defaults2 = { listLen : defaults.ulist.children().length } $.extend(defaults, defaults2); $.extend(options, defaults); // do other stuff } The above code samples are just thrown together, and only meant to get the idea across to you. Anyway, is there a better way to do this?

  • Database table design vs. ease of use.

    - by Gastoni
    I have a table with 3 fields: color, fruit, date. I can pick 1 fruit and 1 color, but I can do this only once each day. examples: red, apple, monday red, mango, monday blue, apple, monday blue, mango, monday red, apple, tuesday The two ways in which I could build the table are: 1.- To have color, fruit and date be a composite primary key (PK). This makes it easy to insert data into the table because all the validation needed is done by the database. PK color PK fruit PK date 2.- Have and id column set as PK and then all the other fields. Many say thats the way it should be, because composite PKs are evil. For example, CakePHP does no support them. PK id color fruit date Both have advantages. Which would be the 'better' approach?

  • What's your favourite programming language, and its killer feature?

    - by eplawless
    Each language I've used has had its pros and cons, but some features have really shone through as being indispensible, shining examples of how to design a programming language to make programmers happy. I use PHP a lot at work, and the one thing I really miss when moving to other languages is PHP's foreach: foreach($items as $item) //iterate through items by value foreach($items as &$item) //iterate through items by reference foreach($items as $i => $item) //by value, with indices foreach($items as $i => &$item) //by reference, with indices In C#, I'm kind of smitten with the built-in multicast delegate system, as well as the way it handles getters and setters. So what's your favourite/favorite language, and what feature makes it awesome?

  • XML DOM Manipuation

    - by kunalsawlani
    Hi, I am new to XML and have been trying some simple examples and they work fine. I want to do something like the following, but I am not able to figure out how to go about doing this. I have a HTML web page, where the user types in some data in an input field. I want to take that data, parse it to create an XML string, and the apply XSLT transformation to it, and display the result back on the page. All this needs to be done on the client browser, with JavaScript. If some one could point out the steps or the general procedure to go about doing this, it would be great. I have been looking over the net, but the information is so vast, that I have not been able to locate exactly what I need. Thanks

  • What is the "Entity" reffering to in fluent Nhibernate Mapping Configuration?

    - by percent20
    I am trying to learn fluent nhibernate better so am doing a basic sample application from scratch, instead of using someone elses framework. However, I am finding I really don't understand what is going on in assigning mapping files. I have seen a lot of code examples which are all showing the same code, but nothing that spells it out. No description of how it works just that it works. Here is a code example that I see often. return Fluently.Configure() .Database(config) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Entity>()) .BuildSessionFactory(); So in the code example what is Entity? and how does that piece of code work? Part of me thinks it is the name of the assembly, but seeing as how the namespace I am using is usually the name of the assembly the compiler complains that I am using a namespace as a type. I feel this is important and am rather flustered by the fact I can't figure it out. Thanks

  • Workflow Foundation: How to create Recieve activity with custom message in xaml designer?

    - by Petr Felzmann
    I need to have Recieve activity which can receive my custom data. I found examples, but all use coded workflows like such public class ProcessRequest : Activity { public ProcessRequest() { Variable<MyData> request = new Variable<MyData> { Name = "request" }; Receive receiveRequest = new Receive { ServiceContractName = "IProcessRequest", OperationName = "Foo", CanCreateInstance = true, Content = ReceiveContent.Create(new OutArgument<MyData>(request)) }; } } The main point is that Recieve.Content property. It is not clear for me how I can do it in XAML designer. What I have to set in the dialog of the Content property - Message or Parameters and what to set inside those options? Thanks for the light!

Will work through and update once working. Anyone wanna beat me to the punch, by all means. Better yet, if you can find a way to be rid of WorkflowDesigner, seems odd it is required.
