  • Javascript: detect when a window is resized ?

    - by Patrick
    Is there any way with jQuery or javascript to trigger a function when the user ends to resize the browser window ? In other terms: 1) Can I detect mouse up event when user is resizing the browser window ? otherwise 2) Can I detect when a window resize operation is finished ? I'm currently only able to trigger an event when the user start to resize the window with jquery thanks

  • Python/Biophysics- Trying to code a simple stochastic simulation!

    - by user359597
    Hey guys- I'm trying to figure out what to make of the following code- this is not the clear, intuitive python I've been learning. Was it written in C or something then wrapped in a python fxn? The code I wrote (not shown) is using the same math, but I couldn't figure out how to write a conditional loop. If anyone could explain/decipher/clean this up, I'd be really appreciative. I mean- is this 'good' python- or does it look funky? I'm brand new to this- but it's like the order of the fxns is messed up? I understand Gillespie's- I've successfully coded several simpler simulations. So in a nutshell- good code-(pythonic)? order? c? improvements? am i being an idiot? The code shown is the 'answer,' to the following question from a biophysics text (petri-net not shown and honestly not necessary to understand problem): "In a programming language of your choice, implement Gillespie’s First Reaction Algorithm to study the temporal behaviour of the reaction A---B in which the transition from A to B can only take place if another compound, C, is present, and where C dynamically interconverts with D, as modelled in the Petri-net below. Assume that there are 100 molecules of A, 1 of C, and no B or D present at the start of the reaction. Set kAB to 0.1 s-1 and both kCD and kDC to 1.0 s-1. Simulate the behaviour of the system over 100 s." def sim(): # Set the rate constants for all transitions kAB = 0.1 kCD = 1.0 kDC = 1.0 # Set up the initial state A = 100 B = 0 C = 1 D = 0 # Set the start and end times t = 0.0 tEnd = 100.0 print "Time\t", "Transition\t", "A\t", "B\t", "C\t", "D" # Compute the first interval transition, interval = transitionData(A, B, C, D, kAB, kCD, kDC) # Loop until the end time is exceded or no transition can fire any more while t <= tEnd and transition >= 0: print t, '\t', transition, '\t', A, '\t', B, '\t', C, '\t', D t += interval if transition == 0: A -= 1 B += 1 if transition == 1: C -= 1 D += 1 if transition == 2: C += 1 D -= 1 transition, interval = transitionData(A, B, C, D, kAB, kCD, kDC) def transitionData(A, B, C, D, kAB, kCD, kDC): """ Returns nTransition, the number of the firing transition (0: A->B, 1: C->D, 2: D->C), and interval, the interval between the time of the previous transition and that of the current one. """ RAB = kAB * A * C RCD = kCD * C RDC = kDC * D dt = [-1.0, -1.0, -1.0] if RAB > 0.0: dt[0] = -math.log(1.0 - random.random())/RAB if RCD > 0.0: dt[1] = -math.log(1.0 - random.random())/RCD if RDC > 0.0: dt[2] = -math.log(1.0 - random.random())/RDC interval = 1e36 transition = -1 for n in range(len(dt)): if dt[n] > 0.0 and dt[n] < interval: interval = dt[n] transition = n return transition, interval if __name__ == '__main__': sim()

  • How do I make a SignalR client something when it receives a message?

    - by Ben
    I want to do something when a client receives a message via a SignalR hub. I've put together a basic chat app, but want people to be able to "like" a chat comment. I'm thinking the way to do this is to find the chat message on the client's page and update it using javascript. In the meantime to "prove the concept" I just want to make an alert popup on the client machine to say another user likes the comment. Trouble is, I'm not sure where to put it. (Am struggling to find SignalR documentation to be honest.) can't get my head round what is calling what here. My ChatHub class is as follows: public class ChatHub : Hub { public void Send(string name, string message) { // Call the broadcastMessage method to update clients. Clients.All.broadcastMessage(name, message); } } And my JavaScript is: $(function () { // Declare a proxy to reference the hub. var chat = $.connection.chatHub; // Create a function that the hub can call to broadcast messages. chat.client.broadcastMessage = function (name, message) { // Html encode display name and message. var encodedName = $('<div />').text(name).html(); var encodedMsg = $('<div />').text(message).html(); // Add the message to the page. var divContent = $('#discussion').html(); $('#discussion').html('<div class="container">' + '<div class="content">' + '<p class="username">' + encodedName + '</p>' + '<p class="message">' + encodedMsg + '</p>' + '</div>' + '<div class="slideout">' + '<div class="clickme" onclick="slideMenu(this)"></div>' + '<div class="slidebutton"><img id="imgid" onclick="likeButtonClick(this)" src="Images/like.png" /></div>' + '<div class="slidebutton"><img onclick="commentButtonClick(this)" src="Images/comment.png" /></div>' + '<div class="slidebutton" style="margin-right:0px"><img onclick="redcardButtonClick(this)" src="Images/redcard.png" /></div>' + '</div>' + '</div>' + divContent); }; // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.start().done(function () { $('#sendmessage').click(function () { // Call the Send method on the hub. chat.server.send($('#lblUser').html(), $('#message').val()); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); });

  • GWT and MVC type calls

    - by arinte
    I have a GWT app that when launched it takes you to a page with just a menu. So as a shortcut type thing I would like the users to be able to go straight to the page they want. So if the default start page is x, the should be able to say x/add and it will take them to the add page. How would I get that in gwt? Do I need a bunch of different entry points?

  • C# threading question

    - by MusiGenesis
    Is there any essential difference between this code: ThreadStart starter = new ThreadStart(SomeMethod); starter.Invoke(); and this? ThreadStart starter = new ThreadStart(SomeMethod); Thread th = new Thread(starter); th.Start(); Or does the first invoke the method on the current thread while the second invokes it on a new thread?

  • UINavigationBar unresponsive after canceling a UITableView search in nav controller in tab bar in a popover

    - by Mark
    Ok, this is an odd one and I can reproduce it with a new project easily. Here is the setup: I have a UISplitViewController. In the left side I have a UITabBarController. In this tab bar controller I have two UINavigationControllers. In the navigation controllers I have UITableViewControllers. These table views have search bars on them. Ok, what happens with this setup is that if I'm in portrait mode and bring up this view in the popover and I start a search in one of the table views and cancel it, the navigation bar becomes unresponsive. That is, the "back" button as well as the right side button cannot be clicked. If I do the exact same thing in landscape mode so we are not in a popover, this doesn't happen. The navigation bar stays responsive. So, the problem only seems to happen inside a popover. I've also noticed that if I do the search but click on an item in the search results which ends up loading something into the "detail view" of the split view and dismissing the popover, and then come back to the popover and then click the Cancel button for the search, the navigation bar is responsive. My application is a universal app and uses the same tab bar controller in the iPhone interface and it works there without this issue. As I mentioned above, I can easily reproduce this with a new project. Here are the steps if you want to try it out yourself: start new project - split view create new UITableViewController class (i named TableViewController) uncomment out the viewDidLoad method as well as the rightBarButtonItem line in viewDidLoad (so we will have an Edit button in the navigation bar) enter any values you want to return from numberOfSectioinsInTableView and numberOfRowsInSection methods open MainWindow.xib and do the following: please note that you will need to be viewing the xib in the middle "view mode" so you can expand the contents of the items drag a Tab Bar Controller into the xib to replace the Navigation Controller item drag a Navigation Controller into the xib as another item under the Tab Bar Controller delete the other two view controllers that are under the Tab Bar Controller (so, now our tab bar has just the one navigation controller on it) inside the navigation controller, drag in a Table View Controller and use it to replace the View Controller (Root View Controller) change the class of the new Table View Controller to the class created above (TableViewController for me) double-click on the Table View under the new Table View Controller to open it up (will be displayed in the tab bar inside the split view controller) drag a "Search Bar and Search Display" onto the table view save the xib run the project in simulator while in portrait mode, click on the Root List button to bring up popover notice the Edit button is clickable click in the Search box - we go into search mode click the Cancel button to exit search mode notice the Edit button no longer works So, can anyone help me figure out why this is happening? Thanks, Mark

  • Multiple subscribers in NServiceBus

    - by Johan Zell
    Hi. I'm getting started with NServiceBus and have a question about the Pubsub sample. My intention was to have multiple instances of Publisher1 running and receiving the message sent from the publisher. I also hacked the Publisher to only send messages of the eventMessage type. But if I start the publisher and three instances of Subscriber1, only one of them gets the message at a time. why is that? Is it a config setting or something else? /J

  • What's the best visual merge tool for Git?

    - by andy
    Title says it. What's the best tool for viewing and editing a merge in Git? I'd like to get a 3-way merge view, with "mine", "theirs" and "output" in separate panels. Also, instructions for invoking said tool would be great. (I still haven't figure out how to start kdiff3 in such a way that it doesn't give me an error) edit: My OS is Ubuntu.

  • Can iFrame Scrollbars be skinned in webkit?

    - by Mr. Bamboo
    It's pretty well known by now that you can style scrollbars using the webkit specific CSS tags (::-webkit-scrollbar-button:start:decrement, ::-webkit-scrollbar-button:end:increment, etc. ). However, I've noticed that I cannot style the scrollbars attached to iFrames. Question: Is there a way to access and style the scrollbars on the iFrame using webkit? (Yes, I've actually got a particular scenario where I'd like to be able to do this.) Thanks much in advance for any help!
