  • How convert a string into a ActiveSupport::TimeWithZone?

    - by Nisanio
    How convert a string into a ActiveSupport::TimeWithZone? My dilemma is this. I need to update a field (called updated_at). The field in mysql is datetime, and the class is ActiveSupport::TimeWithZone. But the dates are strings like "10/17/2008". I used "10/17/2008".to_date (And I intend .to_time and to_datetime), and even if in console the ActiveRecord class save succesfully, the field in the database still is the current date... Thanks in advanced.

  • Install Trac on 64bits Windows 7

    - by Tufo
    I'm configuring a new Developing Server that came with Windows 7 64bits. It must have installed Trac with Subversion integration. I install Subversion with VisualSVN 2.1.1, clients with TortoiseSVN 1.6.7 and AnkhSVN 2.1.7 for Visual Studio 2008 SP1 integration. All works fine! my problem begun when going to Trac installation. I install python 2.6 all fine. Trac hasn't a x64 windows installer, so I installed it manually by compiling it with python console (C:\Python26\python.exe C:/TRAC/setup.py install). After that, I can create TRAC projects normally, the Trac core is working fine. And so the problem begins, lets take a look at the Trac INSTALL file: Requirements To install Trac, the following software packages must be installed: Python, version = 2.3. Subversion, version = 1.0. (= 1.1.xrecommended) Subversion SWIG Python bindings (not PySVN). PySQLite,version 1.x (for SQLite 2.x) or version 2.x (for SQLite 3.x) Clearsilver, version = 0.9.3 (0.9.14 recommended) Python: OK Subverion: OK Subversion SWIG Python bindings (not PySVN): Here I face the first issue, he asks me for 'cd' to the swig directory and run the 'configure' file, and the result is: C:\swigwin-1.3.40> c:\python26\python.exe configure File "configure", line 16 DUALCASE=1; export DUALCASE # for MKS sh ^ SyntaxError: invalid syntax PySQLite, version 1.x (for SQLite 2.x) or version 2.x (for SQLite 3.x): Don't need, as Python 2.6 comes with SQLLite Clearsilver, version = 0.9.3 (0.9.14 recommended): Second issue, Clearsilver only has 32bit installer wich does not recognize python installation (as registry keys are in different places from 32 to 64 bits). So I try to manually install it with python console. It returns me a error of the same kind as SWIG: C:\clearsilver-0.10.5>C:\python26\python.exe ./configure File "./configure", line 13 if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then ^ SyntaxError: invalid syntax When I simulate a web server using the "TRACD" command, it runs fine when I disable svn support but when I try to open the web page it shows me a error regarding ClearSilver is not installed for generating the html content. AND (for making me more happy) This TRAC will run over IIS7, I mustn't install Apache... I'm nearly crazy with this issue... HELP!!!

  • Facebook FXBML since Yesterday not rendering (IFRAME Canvas)

    - by ArneRie
    Hi Folks, since yesterday is my app not rendering the xfbml Tags (name and picture). Iam using the new JavaScript SDK inside an Canvas-Iframe Application. Firebug tells me the following inside the console: Get: http://0.channel20.facebook.com/x/3332504234/true/p_1348362044=0 And after a while: XFBML tags failed to render in 30000ms. Does someone has the same problems, or know why this happens?

  • How to supress Powershell window when using the -File option

    - by guillermooo
    I'm calling Powershell like so: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noprofile -noninteractive -nologo -file "C:\Users\dummy\Documents\dev\powershell\samples\test.ps1" I'm calling it from a python script, but the same problem can be observed if called via a shortcut. I thought the -NonInteractive flag would cause Poweshell to execute in a hidden window, but it doesn't. Is there a way of supressing the console window when calling Powershell from an external application? Solution based on Johannes Rössel suggestion st_inf = subprocess.STARTUPINFO() st_inf.dwFlags = st.inf.dwFlags | subprocess.STARTF_USESHOWWINDOW Popen(["notepad"], startupinfo=st_inf)

  • Mono vs .NET Interop curiosity

    - by Olaseni
    I'm developing a huge console application for Unix using C# via Mono. If I develop that app using M Visual Studio and .NET 3.5 and I carefully neglect to use win32 specific API calls, should I expect that application to automatically work in my Unix box? Or should I just get MonoDevelop and go the Mono way?

    Inspite of putting the following meta tag I am not getting the expected result: <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" > I open the developer tool window. In the same bar where the menu appears there is an item called Browser Mode: it still shows IE 8 by default. Even doing document.documentMode in the console window shows "8". Am I doing anything wrong?

  • C# Begin/EndReceive - how do I read large data?

    - by ryeguy
    When reading data in chunks of say, 1024, how do I continue to read from a socket that receives a message bigger than 1024 bytes until there is no data left? Should I just use BeginReceive to read a packet's length prefix only, and then once that is retrieved, use Receive() (in the async thread) to read the rest of the packet? Or is there another way? edit: I thought Jon Skeet's link had the solution, but there is a bit of a speedbump with that code. The code I used is: public class StateObject { public Socket workSocket = null; public const int BUFFER_SIZE = 1024; public byte[] buffer = new byte[BUFFER_SIZE]; public StringBuilder sb = new StringBuilder(); } public static void Read_Callback(IAsyncResult ar) { StateObject so = (StateObject) ar.AsyncState; Socket s = so.workSocket; int read = s.EndReceive(ar); if (read > 0) { so.sb.Append(Encoding.ASCII.GetString(so.buffer, 0, read)); if (read == StateObject.BUFFER_SIZE) { s.BeginReceive(so.buffer, 0, StateObject.BUFFER_SIZE, 0, new AyncCallback(Async_Send_Receive.Read_Callback), so); return; } } if (so.sb.Length > 0) { //All of the data has been read, so displays it to the console string strContent; strContent = so.sb.ToString(); Console.WriteLine(String.Format("Read {0} byte from socket" + "data = {1} ", strContent.Length, strContent)); } s.Close(); } Now this corrected works fine most of the time, but it fails when the packet's size is a multiple of the buffer. The reason for this is if the buffer gets filled on a read it is assumed there is more data; but the same problem happens as before. A 2 byte buffer, for exmaple, gets filled twice on a 4 byte packet, and assumes there is more data. It then blocks because there is nothing left to read. The problem is that the receive function doesn't know when the end of the packet is. This got me thinking to two possible solutions: I could either have an end-of-packet delimiter or I could read the packet header to find the length and then receive exactly that amount (as I originally suggested). There's problems with each of these, though. I don't like the idea of using a delimiter, as a user could somehow work that into a packet in an input string from the app and screw it up. It also just seems kinda sloppy to me. The length header sounds ok, but I'm planning on using protocol buffers - I don't know the format of the data. Is there a length header? How many bytes is it? Would this be something I implement myself? Etc.. What should I do?

  • problem with reload data from table view after come back from another view

    - by user129677
    I have a problem in my application. Any help will be greatly appreciated. Basically it is from view A to view B, and then come back from view B. In the view A, it has dynamic data loaded in from the database, and display on the table view. In this page, it also has the edit button, not on the navigation bar. When user tabs the edit button, it goes to the view B, which shows the pick view. And user can make any changes in here. Once that is done, user tabs the back button on the navigation bar, it saves the changes into the NSUserDefaults, goes back to the view A by pop the view B. When coming back to the view A, it should get the new data from the UIUserDefaults, and it did. I user NSLog to print out to the console and it shows the correct data. Also it should invoke the viewWillAppear: method to get the new data for the table view, but it didn't. It even did not call the tableView:numberOfRowsInSection: method. I place a NSLog statement inside this method but didn't print out in the console. as the result, the view A still has the old data. the only way to get the new data in the view A is to stop and start the application. both view A and view B are the subclass of UIViewController, with UITableViewDelegate and UITableViewDataSource. here is my code in the view A : - (void)viewWillAppear:(BOOL)animated { NSLog(@"enter in Schedule2ViewController ..."); // load in data from database, and store into NSArray object //[self.theTableView reloadData]; [self.theTableView setNeedsDisplay]; //[self.theTableView setNeedsLayout]; } in here, the "theTableView" is a UITableView variable. And I try all three cases of "reloadData", "setNeedsDisplay", and "setNeedsLayout", but didn't seem to work. in the view B, here is the method corresponding to the back button on the navigation bar. - (void)viewDidLoad { UIBarButtonItem *saveButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSave target:self action:@selector(savePreference)]; self.navigationItem.leftBarButtonItem = saveButton; [saveButton release]; } - (IBAction) savePreference { NSLog(@"save preference."); // save data into the NSUSerDefaults [self.navigationController popViewControllerAnimated:YES]; } Am I doing in the right way? Or is there anything that I missed? Many thanks.

  • Single-Stage vs Two-Stage Animation for iPhone Apps?

    - by Devoted
    What are single-state and two-stage animation for rotating an iPhone window? This is the "error" message I get in the Debugger Console (nothing crashes): Using two-stage rotation animation. To use the smoother single-stage animation, this application must remove two-stage method implementations. I was working through the book "Beginning iPhone Development: Exploring the iPhone SDK" by Apress (Dave Mark, Jeff LaMarche) on the Swap Project.

  • How is IObservable<double>.Average supposed to work?

    - by Dan Tao
    Update Looks like Jon Skeet was right (big surprise!) and the issue was with my assumption about the Average extension providing a continuous average (it doesn't). For the behavior I'm after, I wrote a simple ContinuousAverage extension method, the implementation of which I am including here for the benefit of others who may want something similar: public static class ObservableExtensions { private class ContinuousAverager { private double _mean; private long _count; public ContinuousAverager() { _mean = 0.0; _count = 0L; } // undecided whether this method needs to be made thread-safe or not // seems that ought to be the responsibility of the IObservable (?) public double Add(double value) { double delta = value - _mean; _mean += (delta / (double)(++_count)); return _mean; } } public static IObservable<double> ContinousAverage(this IObservable<double> source) { var averager = new ContinuousAverager(); return source.Select(x => averager.Add(x)); } } I'm thinking of going ahead and doing something like the above for the other obvious candidates as well -- so, ContinuousCount, ContinuousSum, ContinuousMin, ContinuousMax ... perhaps ContinuousVariance and ContinuousStandardDeviation as well? Any thoughts on that? Original Question I use Rx Extensions a little bit here and there, and feel I've got the basic ideas down. Now here's something odd: I was under the impression that if I wrote this: var ticks = Observable.FromEvent<QuoteEventArgs>(MarketDataProvider, "MarketTick"); var bids = ticks .Where(e => e.EventArgs.Quote.HasBid) .Select(e => e.EventArgs.Quote.Bid); var bidsSubscription = bids.Subscribe( b => Console.WriteLine("Bid: {0}", b) ); var avgOfBids = bids.Average(); var avgOfBidsSubscription = avgOfBids.Subscribe( b => Console.WriteLine("Avg Bid: {0}", b) ); I would get two IObservable<double> objects (bids and avgOfBids); one would basically be a stream of all the market bids from my MarketDataProvider, the other would be a stream of the average of these bids. So something like this: Bid Avg Bid 1 1 2 1.5 1 1.33 2 1.5 It seems that my avgOfBids object isn't doing anything. What am I missing? I think I've probably misunderstood what Average is actually supposed to do. (This also seems to be the case for all of the aggregate-like extension methods on IObservable<T> -- e.g., Max, Count, etc.)

  • Destructuring assignment problem

    Why does for ([] in iterable); work fine but [void 0 for ([] in iterable)] throw a syntax error for invalid left-hand assignment?
