  • If a jQuery function calls itself in its completion callback, is that a recursive danger to the stac

    - by NXT
    Hi, I'm writing a little jQuery component that animates in response to button presses and also should go automatically as well. I was just wondering if this function recursive or not, I can't quite work it out. function animate_next_internal() { $('#sc_thumbnails').animate( { top: '-=106' }, 500, function() { animate_next_internal(); } ); } My actual function is more complicated to allow for stops and starts, this is just a simplified example.

  • DataContractSerializer: preserve string member that happens to be raw xml?

    - by bwerks
    I'm a little inexperienced with the DataContract paradigm, and I'm running into a deserialization problem. I have a field that's a string, but it contains xml and it's not being deserialized correctly. I have a feeling that it's because the DCS is treating it as input to the serializer and not as an opaque string object. Is there some way to mark a DataMember in code to say "This thing is a string, don't treat its contents as xml" similar to XmlIgnore? Thanks!

  • Why MyModel.all works in Rails ?

    - by AntonAL
    Hi, i don't understand this little thing: Suppose, we have "Person" model class Person < ActiveRecord::Base end Why Person.all works ? Person.all.each { |p| do_something } This syntax tells us, that we have Person class-object instanciated somewhere ? Or is it some convention over configuration case ?

  • Is there an easy way to stream a m3u in iPhone?

    - by marty
    I can have a UIWebView with the .m3u file opened, which will go to the webview with a play button displayed, and that automatically goes to the quicktime player and starts playing the stream. But when I press the done button, it goes back to the UIWebView with a little play button in the middle, and from there you can go back to the previous screen (it was selected from a tableview). So I just want it to automatically load the quicktime player in the view. How can I do that?

    - by user576844
    I am trying to write a program containing two source files: main program written in C and assembly(x86 32 and 64) module callable from C. The C declaration for the assembly routine looks like this: void mirrorbmp1(void *img, int width, int height) The task involves Mirror/flipping a 1 bpp .BMP image horizontally while Handling any image width properly, not only multiples of 8. I am new to assembly programming and have very little idea about how i should do the ask. Any help would be appreciated.

  • Is there a full REPL for Erlang?

    - by Gabriel Cuvillier
    Is there a way to have a full interpreter in Erlang, not just a "shell". Since it is a dynamic language, not being able to define named functions in the interpreter is a little bit disappointing... I suspect that it is because compilation units (modules) must be explicitly compiled for their execution by the VM, but maybe a REPL acting as a dynamic/recompilable module exist?

  • Are there algorithms for increasing resolution of an image?

    - by David
    Are there any algorithms or tools that can increase the resolution of an image - besides just a simple zoom that makes each individual pixel in the image a little larger? I realize that such an algorithm would have to invent pixels that don't really exist in the original image, but I figured there might be some algorithm that could intelligently figure out what pixels to add to the image to increase its resolution.

  • Generic JSON parser in .NET / WPF?

    - by niklassaers
    I've read lots of tutorials on how to deserialize a JSON object to an object of a particular using DataContractJsonSerializer. However, I'd like to deserialize my object to a Dictionary consisting of either Strings, Arrays or Dictionaries, such as System.Json does with SilverLight when I say JsonObject.Parse(myJSONstring). Is there an equivalent to System.Json that I can use in my WPF project? (just a short background: I'm fetching JSON objects that have way to much info, and I just want to use a little bit to fill out a String array) Cheers Nik

  • How to make NetBeans IDE 6.8 show svn commit status (especially for "dirty" files)

    - by Andrew M. Andrews III
    I just switched from Eclipse to NetBeans IDE 6.8 for my PHP/Ajax development. Eclipse always showed a little hard disk symbol over the file icon for files that were in sync with the svn repository, and an asterisk for files with changes that have not been committed. Is there a way to see the commit status in NetBeans? If not, what is your preferred way of recognizing which files to commit?

  • C#. How to terminate a thread which has spawned another thread which is sleeping?

    - by Bobb
    I have a long running thread made from Thread.Start(). It spawns a background thread using QueueUserWorkItem which sleeps most of the time. Then the class-owner get disposed I call thread1.Join() but naturally it doesnt return because its child background thread is sleeping. What would be the right solution to gracefully terminate a thread which has other threads with little hassle? Thanks

  • HTML - Which element to output text?

    - by Oliver Weiler
    I'm implementing a little chat application where I receive messages from a server, which I would like to display to a user. As I'm more of a backend guy, and lacking experience in frontend development, I don't know which element would be suited best to output the text. Two options come to my mind: Using a plain div Using a textarea (as far as I understand, this is intended to be used for input). (Would also be nice if I could somehow fade in the text using JQuery).

  • Code indentation helper for gedit (python).

    - by aviraldg
    See the little vertical lines? They're damn helpful when writing Python code. Any chance I could get something similar for gedit? I wouldn't mind having to write my own plugin, as long as it's in Python... So: Is there a plugin for this in gedit? If not, would it be possible to write one in Python.

  • Fixing VB6 inaccurate mathmetical results due to rounding

    - by jay
    Try running this in a .VBS file MsgBox(545.14-544.94) You get a neat little answer of 0.199999999999932! This rounding issue also occurs unfortunately in Sin(2 * pi) since VB can only ever see the (user defined) variable pi as accurate as 3.14159265358979. Is rounding it manually (and loosing accuracy) the only way to improve the result? What is the most effective way of dealing with this kind of problem?

  • Whats better query with long where in condition or many small queries?

    - by DCrystal
    Maybe it's a little dumb, but i'm just not sure what is better. If i have to check about 30k rows in db for existanse, what i'd do? #1 - one query select id from table1 where name in (smth1,smth2...{till 30k}) #2 - many queries select id from table1 where name=smth1 Though, perfomance is not the goal, i don't want to go down with mysql either ;) Maybe, any other solutions will be more suitable... Thanks.

  • Export symbol as png

    - by Etiennebr
    I'd like to export plotting symbols form R as a png graphic. But I haven't found a perfect way yet. Using png("symbol.png",width=20, height=20, bg="transparent") par(mar=c(0,0,0,0)) plot.new() symbols(1, 1, circles=0.3, bg=2, inches=FALSE, lwd=2, bty="n") dev.off() creates a little border around the symbol (I'd like it to be transparent) and the symbol isn't filling the whole space. Is there a more specific way of doing this ?

  • Need to have testing server work with https: but don't have an SSL

    - by Cyrcle
    I'm working on an online store. I have it setup on my testing server. I'm having a problem where when it goes to the checkout functions it wants to start calling https pages. I don't have an SSL certificate for this server. Is there something I can do with Apache to get this to work? Mod_Rewrite perhaps? I've played a little with rewrites but haven't had any success.

  • Tool to monitor HTTP, TCP, etc. Web Service traffic

    - by huseyint
    What's the best tool that you use to monitor Web Service, SOAP, WCF, etc. traffic that's coming and going on the wire? I have seen some tools that made with Java but they seem to be a little crappy. What I want is a tool that sits in the middle as a proxy and does port redirection (which should have configurable listen/redirect ports). Are there any tools work on Windows to do this?

  • Javascript self contained sandbox events and client side stack

    - by amnon
    I'm in the process of moving a JSF heavy web application to a REST and mainly JS module application . I've watched "scalable javascript application architecture" by Nicholas Zakas on yui theater (excellent video) and implemented much of the talk with good success but i have some questions : I found the lecture a little confusing in regards to the relationship between modules and sandboxes , on one had to my understanding modules should not be effected by something happening outside of their sandbox and this is why they publish events via the sandbox (and not via the core as they do access the core for hiding base libary) but each module in the application gets a new sandbox ? , shouldn't the sandbox limit events to the modoules using it ? or should events be published cross page ? e.g. : if i have two editable tables but i want to contain each one in a different sandbox and it's events effect only the modules inside that sandbox something like messabe box per table which is a different module/widget how can i do that with sandbox per module , ofcourse i can prefix the events with the moduleid but that creates coupling that i want to avoid ... and i don't want to package modules toghter as one module per combination as i already have 6-7 modules ? while i can hide the base library for small things like id selector etc.. i would still like to use the base library for module dependencies and resource loading and use something like yui loader or dojo.require so in fact i'm hiding the base library but the modules themself are defined and loaded by the base library ... seems a little strange to me libraries don't return simple js objects but usualy wrap them e.g. : u can do something like $$('.classname').each(.. which cleans the code alot , it makes no sense to wrap the base and then in the module create a dependency for the base library by executing .each but not using those features makes a lot of code written which can be left out ... and implemnting that functionality is very bug prone does anyonen have any experience with building a front side stack of this order ? how easy is it to change a base library and/or have modules from different libraries , using yui datatable but doing form validation with dojo ... ? some what of a combination of 2+4 if u choose to do something like i said and load dojo form validation widgets for inputs via yui loader would that mean dojocore is a module and the form module is dependant on it ? Thanks .
