  • jQuery: How to collect values from sliders into simple object with id as keys

    - by Svish
    I have several jQuery UI Sliders and I want to collect their values. Thought it would be a simple task, but when I was going to do it I got stuck and not quite sure what to do anymore :p The object I would like to end up with should look something like this: { a: 80, b: 90, c: 20, ... } I can do it manually like this: var values = { a: $('#a').slider('value'), b: $('#b').slider('value'), c: $('#c').slider('value'), ... }; But that's a bit tedious, especially if I need to add or remove or rename. Was hoping I could do something with the map or each function or something like that, but I can't figure it out. Anyone have some clever ideas?

  • Solution for distributing MANY simple network tasks?

    - by EmpireJones
    I would like to create some sort of a distributed setup for running a ton of small/simple REST web queries in a production environment. For each 5-10 related queries which are executed from a node, I will generate a very small amount of derived data, which will need to be stored in a standard relational database (such as PostgreSQL). What platforms are built for this type of problem set? The nature, data sizes, and quantities seem to contradict the mindset of Hadoop. There are also more grid based architectures such as Condor and Sun Grid Engine, which I have seen mentioned. I'm not sure if these platforms have any recovery from errors though (checking if a job succeeds). What I would really like is a FIFO type queue that I could add jobs to, with the end result of my database getting updated. Any suggestions on the best tool for the job?

  • A simple string array Iteration in C# .NET doesn't work

    - by met.lord
    This is a simple code that should return true or false after comparing each element in a String array with a Session Variable. The thing is that even when the string array named 'plans' gets the right attributes, inside the foreach it keeps iterating only over the first element, so if the Session Variable matches other element different than the first one in the array it never returns true... You could say the problem is right there in the foreach cicle, but I cant see it... I've done this like a hundred times and I can't understand what am I doing wrong... Thank you protected bool ValidatePlans() { bool authorized = false; if (RequiredPlans.Length > 0) { string[] plans = RequiredPlans.Split(','); foreach (string plan in plans) { if (MySessionInfo.Plan == plan) authorized = true; } } return authorized; }

  • Good simple C/C++ FTP and SFTP client library recommendation for embedded Linux

    - by Roman Nikitchenko
    Could anyone recommend FTP / SFTP client C/C++ library for Linux-based embedded system? I know about Curl library but I need something as simple as possible just to download files from FTP / SFTP servers. Is there any recommendation to look for? Yes, SFTP support is critical. Actually I can even sacrifice multi-threading because I need only one stream at a time. And I'd like it to be able to work through memory buffers but this should be not a problem. Thank you in advance.

  • Laying out JPanels to make a simple GUI

    - by Elvis
    Hello, first of all, this is more or less my first GUI and ive learned Java for not more then a week, so it might contain some serious programming errors. What i have right now is: Buttons and labels are part of OptionPanel and are on the left, DrawingPanel is about 5x5 px in size and is on the right. What I am trying to do is a simple test, to get me more familiar with the GUI. The rectangle should be movable and re-sizeable by the user when clicking the respective buttons: http://www.upload.ee/image/612005/JFrame2.jpg Right now i have: JFrame MainFrame - Makes JFrame (Not using the setSize function. using .pack() instead. not sure about it) JPanel MergedPanel - FlowLayout - Adds JPanel OptionsPanel and JPanel DrawingPanel together and gets injected to JFrame MainFrame JPanel DrawPanel - This JPanel is responsible of drawing the rectangle. JPanel OptionPanel - FlowLayout - This JPanel is responsible of the buttons. Help please.

  • Simple iPhone tally method question

    - by Rob
    Just trying to create a simple method that counts up 1 on the tally when the button is pressed. My knowledge is extremely limited and I am pretty sure that my problem is somewhere in the method implementation: -(IBAction) updateTally:(id) sender { NSString *text; int total = 0; total = total + 1; text=[[NSString alloc] initWithFormat: @"%i", total]; lblTally.text = text; } I have done the necessary interface declarations for the lblTally UILabel and the updateTally method. I suspect that there is some sort of an NSString/int/%i/%@ mixup that I am making but I'm not sure how to fix it. When I run the program as it currently is it displays a 0 in the lblTally label field on the iphone. When I press the button it then displays a 1 in that field. However, if I continue to press the button - nothing happens.

    - by Audel
    Hi, I know is a rather simple question but I just can't find an appropriate example in google or anywhere. I've got this piece int numberOfPlays = int.Parse(textBox2.Text); numberOfPlays = (numberOfPlays++); textBox2.Text = (numberOfPlays.ToString()); MessageBox.Show(numberOfPlays.ToString()); So basically what I want to do is to get the value of the textBox2, make it an integer and then add 1 to it. I can't think of any more details right now, so if i'm not clear enough please ask Thanks in advance

  • Approximate photo of a simple drawing using lines

    - by user3704596
    As an input I have a photo of a simple symbol, e.g.: https://www.dropbox.com/s/nrmsvfd0le0bkke/symbol.jpg I would like to detect the straight lines in it, like points of start and ends of the lines. In this case, assuming the top left of the symbol is (0,0), the lines would be defined like this: start end (coordinates of beginning and end of a line) 1. (0,0); (0,10) (vertical line) 2. (0,10); (15, 15) 3. (15,15); (0, 20) 4. (0,20); (0,30) How can I do it (pereferably using OpenCV)? I though about Hough lines, but they seem to be good for perfect thin straight lines, which is not the case in a drawing. I'll probably work on binarized image, too.

    Does this simple cache class need thread synchronization ... if I remove the lock _syncLock statement will encounter any problems?

    I have written a snippet of code in javascript, for a prompt to appear when clicked.

  • scala xml rewrite rule (or, simple pattern help)

    - by williamstw
    I'm missing some fairly simple syntax I gather. I'm trying to rewrite an element label to something else and keep everything else intact. object htmlRule extends RewriteRule { override def transform(n: Node): Seq[Node] = n match { case Elem(prefix, "document", attribs, scope, child@_*) => Elem(prefix, "html", attribs, scope, child) case other => other } } Now, I ask for an explanation of two things: 1) What exactly does "child@_*" mean in plain English? 2) How can I capture the value of "child@_*" and just let it pass right through to the new element? Currently, I get the following error, which makes sense. [error] found : Seq[scala.xml.Node] [error] required: scala.xml.Node [error] Elem(prefix, "html", attribs, scope, child) I'm not wedded to this either, so if there's a better way to simply change the element name of a specific node, let's here it... Thanks, --tim

  • Simple Version Contol

    - by JM01
    We work on a lot of small website projects. There are three of us in different physical locations. I would like a system that is very simple where the main concern is checking out and checking in web files (php, css, images, js) so that we don't accidentally overwrite each other's code. We also need a way to synch our local file systems with the files on the webserver and with each other. Rolling back to older versions is nice but features like branching and merging are not important. It seems like GIT may be overkill for our purpose or maybe not. Can you recommend anything?

  • Simple performance testing tool in C#?

    - by Tomas
    Hi, At first -I need to do it as my university project so I am not interested in using existing tools. I would like to know whether it is even possible to write a very simple tool that I could use for performance testing of web applications. It would only record actions (I do not know, maybe just packet sniffering?) and then replay. However I have basic idea (record packets on port 80 and sending them again), I do not know how to measure time for each transaction as they are not differentiated. Any help is greatly appreciated, thank you!
