  • Parsing a complicated array with GetJSON Jquery

    - by Ozaki
    TLDR: Started with this question simplified it after got some of it working and continuing it here. I need to 'GET' the JSON array Format it correctly and for each within the array place it in the corresponding DIV. ?? It works. This is a followup from this question to simplify and continue. I need to some complicated JSON data from an array. With it I need the title and it's value. The reason why I am doing this is because I will know what the array is called but not the data that is being generated inside it. Lets say this new array looks as follows: {"Days": ["Sunday":"10.00", "Monday":"12.00", "Tuesday":"09.00", "Wednesday":"10.00", "Thursday":"02.00", "Friday":"05.00", "Saturday":"08.00"] } I would need it to get Sunday & 10.00 as well as the same for all of the others. My code to parse this at the moment is as follows: $.getJSON(url, function(data){ $.each(data, function(i,item){ $('.testfield').append('<p>' + item + '</p>'); }); }); Without the added times on each date it will parse the data as follows: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday With the times added to the days in the array Firebug no longer recognizes it as a JSON string. So I am guessing I have formatted something wrong here. Also, I need each day & time to be on a new line I thought that $('.testfield').append('<p>' + item + '</p>' + '<br />'); Would have applied each one to a new line but that did not work. How do I get each day or item to be on a new line? How do I get the $getjson to parse the data correctly day and its value, into a div?

  • Want to learn Objective-C but syntax is very confusing

    - by Sahat
    Coming from Java background I am guessing this is expected. I would really love to learn Objective-C and start developing Mac apps, but the syntax is just killing me. For example: -(void) setNumerator: (int) n { numerator = n; } What is that dash for and why is followed by void in parenthesis? I've never seen void in parenthesis in C/C++, Java or C#. Why don't we have a semicolon after (int) n? But we do have it here: -(void) setNumerator: (int) n; And what's with this alloc, init, release process? myFraction = [Fraction alloc]; myFraction = [myFraction init]; [myFraction release]; And why is it [myFraction release]; and not myFraction = [myFraction release]; ? And lastly what's with the @ signs and what's this implementation equivalent in Java? @implementation Fraction @end I am currently reading Programming in Objective C 2.0 and it's just so frustrating learning this new syntax for someone in Java background.

  • VPython in Eclipse - thinks it has the wrong architecture type.

    - by Duncan Tait
    Evening, So I've recently installed VPython on my MacBook (OS X, Snow Leopard) - and it works absolutely fine in IDLE and from the command line (interactive mode). However, eclipse has issues. Firstly it couldn't find it (which is a bit of an issue actually with all these 'easy install' python modules - when they don't tell you where they actually install to!) but I searched it out in the depths of Library\Frameworks... and added that to the System PYTHONPATH listbox in Eclipse. Now it can find it, but it says the following: Traceback (most recent call last): File "/Users/duncantait/dev/workspace/Network_Simulation/src/Basic/Net_Sim1.py", line 15, in <module> import visual File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/__init__.py", line 59, in <module> import cvisual ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/cvisual.so, 2): no suitable image found. Did find: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/cvisual.so: mach-o, but wrong architecture I am guessing that VPython might not be built for a 64-bit architecture (Intel), but the fact remains that it works in both IDLE and command prompt... So there must be a way to configure Eclipse to run it right? (Wishful thinking). Thanks for any help! Duncan

  • Using jQuery delay() with separate elements

    - by boomturn
    I want to fake a simple animation on page load by sequentially revealing several pngs, each appearing instantly but with unique, precisely timed delay before the next one. Using the latest version of jQuery (1.4.2 at writing), which provides a delay method. My first (braindead) impulse was: $('#image1').show('fast').delay(800); $('#image2').show('fast').delay(1200); $('#image3').show('fast'); Of course all come up simultaneously. jQuery doc examples refer to a single item being chained, not handling multiple items. OK... try again using nested callbacks from show(): $('#image1').show('fast', function() { $('#image2').show('fast', function() { $('#image3').show('fast', function() { }); }); }); Looks ugly (imagine doing 10, also wonder what processor hit would be) but hey, it works sequentially! Without delay though. So... chain delay() after show() using a callback function from it (not even sure if it supports one): $('#image1').show('fast').delay(800, function() { $('#image2').show('fast').delay(1200, function() { $('#image3').show('fast'); }); }); Hm. Opposite result of what I thought might happen: the callback works, but still no delay. So... should I be using some combination of queue and delay instead of nested callbacks? jQuery doc examples for queue again only use one element for example. Guessing this would involve using a custom queue, but am uncertain how to implement this. Or maybe I'm missing a simple way? (For a simple problem!)

  • Slow MySQL Query Breaking my back!

    - by Chris n
    so, I have tried everything I can think of, and can't get this query to happen in less than 3 seconds on my local server. I know the problem has to do with the OR referencing both the owner_id and the person_id. if I run one or the other it happens instantly, but together with an or I can't seem to make it work - I looked into rewriting the code, but the way the app was designed it won't be easy. is there a way I can call an equivalent or that won't take so long? here is the sql: SELECT event_types.name as event_type_name,event_types.id as id, count(events.id) as count,sum(events.estimated_duration) as time_sum FROM events,event_types WHERE event_types.id = events.event_type_id AND events.event_type_id != '4' AND ( events.status!='cancelled') AND events.event_type_id != 64 AND ( events.owner_id = 161 OR events.person_id = 161 ) GROUP BY event_types.name ORDER BY event_types.name DESC; Here's the Explain soup, although I'm guessing it's unnecessary cause there is probably a better way to structure that or that is obvious: thanks so much! chris. +----+-------------+-------------+-------+---------------------------------------------------------------------------------------------------------+-------------------------------+---------+-------------------------------------+------+----------------------------------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------------+-------+---------------------------------------------------------------------------------------------------------+-------------------------------+-- | 1 | SIMPLE | event_types | range | PRIMARY | PRIMARY | 4 | NULL | 78 | Using where; Using temporary; Using filesort | | 1 | SIMPLE | events | ref | index_events_on_status,index_events_on_event_type_id,index_events_on_person_id,index_events_on_owner_id | index_events_on_event_type_id | 5 | thenumber_production.event_types.id | 907 | Using where | +----+-------------+-------------+-------+---------------------------------------------------------------------------------------------------------+-------------------------------+---------+-------------------------------------+------+----------------------------------------------+

  • 2D Ball Collisions with Corners

    - by Aaron
    I'm trying to write a 2D simulation of a ball that bounces off of fixed vertical and horizontal walls. Simulating collisions with the faces of the walls was pretty simple--just negate the X-velocity for a vertical wall or the Y-velocity for a horizontal wall. The problem is that the ball can also collide with the corners of the walls, where a horizontal wall meets with a vertical wall. I have already figured out how to detect when a collision with a corner is occurring. My question is how the ball should react to this collision--that is, how its X and Y velocities will change as a result. Here's a list of what I already know or know how to find: *The X and Y coordinates of the ball's center during the frame when a collision is detected *The X and Y components of the ball's velocity *The X and Y coordinates of the corner *The angle between the ball's center and the corner *The angle in which the ball is traveling just before the collision *The amount that the ball is overlapping the corner when the collision is detected I'm guessing that it's best to pretend that the corner is an infinitely small circle, so I can treat a collision between the ball and that circle as if the ball were colliding with a wall that runs tangent to the circles at the point of collision. It seems to me that all I need to do is rotate the coordinate system to line up with this imaginary wall, reverse the X component of the ball's velocity under this system, and rotate the coordinates back to the original system. The problem is that I have no idea how to program this. By the way, this is an ideal simulation. I'm not taking anything like friction or the ball's rotation into account. I'm using Objective-C, but I'd really just like a general algorithm or some advice. Many thanks if anyone can help!

  • SmtpClient.SendAsync - How to ensure my application doesn't finish before callback?

    - by James
    Hi, I need to send emails asychronously through a console application. I need to do some DB updates on the callback but my application is exiting before the callback code gets run! How can I stop this from happening in a nice manner rather than simply guessing how long to wait before exiting. I would imagine the Async calls get placed in some form of thread? Is it possible to check if any are waiting to be called? Sample Code private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. String token = (string) e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { // update DB Console.WriteLine("Message sent."); } } public static void Main(string[] args) { var users = Repository.GetUsers(); SmtpClient client = new SmtpClient("Host"); client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback); MailAddress from = new MailAddress("[email protected]", "System", Encoding.UTF8); foreach (var user in users) { MailAddress to = new MailAddress(user.Email); MailMessage message = new MailMessage(from, to); message.Body = "This is a test"; message.BodyEncoding = System.Text.Encoding.UTF8; message.Subject = "test message 1" + someArrows; message.SubjectEncoding = System.Text.Encoding.UTF8; string userState = String.Format("Message for user id {0}", user.ID); client.SendAsync(message, userState); message.Dispose(); } // need to wait here until I have received a callback for each message // otherwise the application will exit }

  • Debugging NSoperation BAD ACCESS within graphics context

    - by Joe
    I tried everything to debug this one but I can't get to the bottom of it. This code lives in a subclass of NSOperation which is processed from a queue: (borders is an ivar NSArray containing 5 UIimage objects) NSMutableArray *images = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < 5; i++) { CGSize size = CGSizeMake(60, 60); UIGraphicsBeginImageContext(size); CGPoint thumbPoint = CGPointMake(6, 6); [controller.image drawAtPoint:thumbPoint]; CGPoint borderPoint = CGPointMake(0, 0); [[borders objectAtIndex:i] drawAtPoint:borderPoint]; [images addObject:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext(); } [images release]; The code works fine most of the time but when I push the iphone by access subviews and pressing lots of buttons on the UI I either get this exception which is trapped by the operation: Exception Load view: *** -[NSCFArray insertObject:atIndex:]: attempt to insert nil or I get this: Program received signal: “EXC_BAD_ACCESS”. The exception is caused because UIGraphicsGetImageFromCurrentImageContext() return nil. I don't know how to debug the EXC_BAD_ACCESS but I'm guessing that this error (in fact both of these errors) is caused by low memory. The debugger stops at the line: [controller.image drawAtPoint:thumbPoint]; As I mentioned I've trapped the exception so I can live with that but the EXC_BAD_ACCESS is more serious. IF this is memory related how can I tell and is it possible to increase the memory available to NSOperation?

  • Why does the MSCVRT library generate conflicts at link time?

    - by neuviemeporte
    I am building a project in Visual C++ 2008, which is an example MFC-based app for a static C++ class library I will be using in my own project soon. While building the Debug configuration, I get the following: warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library After using the recommended option (by adding "msvcrt" to the "Ignore specific library" field in the project linker settings for the Debug configuration), the program links and runs fine. However, I'd like to find out why this conflict occured, why do I have to ignore a critical library, and if I'm to expect problems later I if add the ignore, or what happens if I don't (because the program builds anyway). At the same time, the Release configuration warns: warning LNK4075: ignoring '/EDITANDCONTINUE' due to '/OPT:ICF' specification warning LNK4098: defaultlib 'MSVCRTD' conflicts with use of other libs; use /NODEFAULTLIB:library I'm guessing that the "D" suffix means this is the debug version of the vc++ runtime, no idea why this gets used this time. Anyway, adding "msvcrtd" to the ignore field causes lots of link errors of the form: error LNK2001: unresolved external symbol imp_CrtDbgReportW Any insight greatly appreciated.

  • Sending wordpress title-value across PHP-pages

    - by VoodooBurger
    I recently made this wordpress blog, where you can sign up a team for an event, when clicking a link under the event post. This link takes you to a sign-up form on another php-page. The link is added in the loop of the events-template like this: <?php query_posts('cat=8');?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <div class="post" id="post-<?php the_ID(); ?>"> <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2> <div id="tilmeldknap"><?php wp_list_pages("title_li=&depth=1&include=63"); ?></div> <?php include (TEMPLATEPATH . '/inc/meta.php' ); ?>... So every upcoming event will have the same sign-up button. All I need now is to somehow send the specific event-post-title along to the sign-page, so that the following form-submit action will contain that title aswell. But since I'm not very good at php it seems like a mystery, altho I bet it's very simple! I'm guessing it's something like: $event=$_POST['single_post_title()'] But how to get the value to the next php-page I have no idea... please help, anyone :) An eksample can be seen throught this link: http://gadebold.dk/events/ The link sais: 'Tilmeld Hold'

  • Qt QFileDialog - native dialogs only with static functions?

    - by darron
    I'm trying to simply save a file. However, I need a filename entered without a suffix to automatically get a default suffix (which setDefaultSuffix() does). I'd rather not completely lose the native save dialog just for this. exec() is not overloaded from QDialog, so it totally bypasses the native hook (ignoring the DontUseNativeDialog option even if it's false). If I disable the file overwrite warning and append the default suffix myself after the function returns, then I'd be re-opening the dialog if the user did not want to overwrite... and that's just ugly. Is there some signal I can catch and quickly inject the default suffix if it's not there? I'm guessing not, since it's a native dialog. Is there something I'm doing wrong with the filter? I only have one filter choice. It should use that extension. This seems pretty lame. Launching the save dialog and simply typing "test" should never result in an extensionless file. "test.", yes. "test" no way. That'll really confuse the users when they hit Load and can't see the file they just saved. I guess the cross-platform part of Qt is giving me lowest common denominator file dialog functionality?

  • Subsonic 3 ActiveRecord nested select for NotIn bug?

    - by Junto
    I have the following Subsonic 3.0 query, which contains a nested NotIn query: public List<Order> GetRandomOrdersForNoReason(int shopId, int typeId) { // build query var q = new SubSonic.Query.Select().Top("1") .From("Order") .Where("ShopId") .IsEqualTo(shopId) .And(OrderTable.CustomerId).NotIn( new Subsonic.Query.Select("CustomerId") .From("Customer") .Where("TypeId") .IsNotEqualTo(typeId)) .OrderDesc("NewId()"); // Output query Debug.WriteLine(q.ToString()); // returned typed list return q.ExecuteTypedList<Order>(); } The internal query appears to be incorrect: SELECT TOP 1 * FROM [Order] WHERE ShopId = @0 AND CustomerId NOT IN (SELECT CustomerId FROM [Customer] WHERE TypeId = @0) ORDER BY NewId() ASC You'll notice that both parameters are @0. I'm assuming that the parameters are enumerated (starting at zero), for each "new" Select query. However, in this case where the two Select queries are nested, I would have expected the output to have two parameters named @0 and @1. My query is based on one that Rob Conery gave on his blog as a preview of the "Pakala" query tool that became Subsonic 3. His example was: int records = new Select(Northwind.Product.Schema) .Where("productid") .In( new Select("productid").From(Northwind.Product.Schema) .Where("categoryid").IsEqualTo(5) ) .GetRecordCount(); Has anyone else seen this behavior? Is it a bug, or is this an error or my part? Since I'm new to Subsonic I'm guessing that this probably programmer error on my part but I'd like confirmation if possible.

  • Securely erasing a file using simple methods?

    - by Jason
    Hello, I am using C# .NET Framework 2.0. I have a question relating to file shredding. My target operating systems are Windows 7, Windows Vista, and Windows XP. Possibly Windows Server 2003 or 2008 but I'm guessing they should be the same as the first three. My goal is to securely erase a file. I don't believe using File.Delete is secure at all. I read somewhere that the operating system simply marks the raw hard-disk data for deletion when you delete a file - the data is not erased at all. That's why there exists so many working methods to recover supposedly "deleted" files. I also read, that's why it's much more useful to overwrite the file, because then the data on disk actually has to be changed. Is this true? Is this generally what's needed? If so, I believe I can simply write the file full of 1's and 0's a few times. I've read: http://www.codeproject.com/KB/files/NShred.aspx http://blogs.computerworld.com/node/5756 http://blogs.computerworld.com/node/5687 http://stackoverflow.com/questions/4147775/securely-deleting-a-file-in-c-net

  • Operator issues with cout

    - by BSchlinker
    I have a simple package class which is overloaded so I can output package data simply with cout << packagename. I also have two data types, name which is a string and shipping cost with a double. protected: string name; string address; double weight; double shippingcost; ostream &operator<<( ostream &output, const Package &package ) { output << "Package Information ---------------"; output << "Recipient: " << package.name << endl; output << "Shipping Cost (including any applicable fees): " << package.shippingcost; The problem is occurring with the 4th line (output << "Recipient:...). I'm receiving the error "no operator "<<" matches these operands". However, line 5 is fine. I'm guessing this has to do with the data type being a string for the package name. Any ideas?

  • R + Bioconductor : combining probesets in an ExpressionSet

    - by Mike Dewar
    Hi, First off, this may be the wrong Forum for this question, as it's pretty darn R+Bioconductor specific. Here's what I have: library('GEOquery') GDS = getGEO('GDS785') cd4T = GDS2eSet(GDS) cd4T <- cd4T[!fData(cd4T)$symbol == "",] Now cd4T is an ExpressionSet object which wraps a big matrix with 19794 rows (probesets) and 15 columns (samples). The final line gets rid of all probesets that do not have corresponding gene symbols. Now the trouble is that most genes in this set are assigned to more than one probeset. You can see this by doing gene_symbols = factor(fData(cd4T)$Gene.symbol) length(gene_symbols)-length(levels(gene_symbols)) [1] 6897 So only 6897 of my 19794 probesets have unique probeset - gene mappings. I'd like to somehow combine the expression levels of each probeset associated with each gene. I don't care much about the actual probe id for each probe. I'd like very much to end up with an ExpressionSet containing the merged information as all of my downstream analysis is designed to work with this class. I think I can write some code that will do this by hand, and make a new expression set from scratch. However, I'm assuming this can't be a new problem and that code exists to do it, using a statistically sound method to combine the gene expression levels. I'm guessing there's a proper name for this also but my googles aren't showing up much of use. Can anyone help?

  • Cannot find symbol - variable

    - by Ben Garside
    I'm new to Java, and I'm trying to get user input, store each line of input as a variable and then return each value so that it can be passed on somewhere else. When I try and compile it is telling me that it can't find the variable magnitude. I'm assuming it won't find the others either. I'm guessing that this is because I've declare the variables inside of the "try" but don't know how to get it so that the return statement accepts them. Code is as follows: public Earthquake userAddEarthquake() { Scanner scanner = new Scanner(System.in); try{ // convert the string read from the scanner into Integer type System.out.println("Please Enter An Earthquake Magnitude: "); Double magnitude = Double.parseDouble(scanner.nextLine()); System.out.println("Please Enter The Earthquakes Latitude Position: "); scanner = new Scanner(System.in); Double positionLatitude = Double.parseDouble(scanner.nextLine()); System.out.print("Please Enter The Earthquakes Longitude Position: "); scanner = new Scanner(System.in); Double positionLongitude = Double.parseDouble(scanner.nextLine()); System.out.print("Please Enter The Year That The Earthquake Occured: "); scanner = new Scanner(System.in); int year = Integer.parseInt(scanner.nextLine()); System.out.println("Magnitude = " + magnitude); } catch(NumberFormatException ne){ System.out.println("Invalid Input"); } finally{ scanner.close(); } return new Earthquake(magnitude, positionLatitude, positionLongitude, year); }

  • Setting Parameters from another Parameter In SSRS

    - by Mike
    I was able to get this working is SSRS 2008, but do to the fact that my company only has 2005 servers I need to downgrade the report to 2005. The idea is for a given person name there are two key fields EntityType and EntityId So I have a parameter from a dataset where the Label is the Name and the value is EntityType_EntityId I use the split function to take the left and right sides of from _ In 2008, I set the query parameters of the dataset to the split function and it works In 2005, I set the Default Value of each Report Parameters Now when I run the report and put textboxes showing the value of the parameters, the values are shown correctly but the query does not run. I am guessing that this is a lifecycle issue being Get Name Parameter Run Report THEN Set Parameters = Split of Name But the problem with that is the second time I run the report I should get result and I do not. Does anyone know what I am doing wrong. I guess I can pass in the underscore delimted string to the stored procedure and parse it there, but my question is can this be done in the report? Reason being other callers will pass in the parameters as two seperate values.

  • Designing a fluent Javascript interface to abstract away the asynchronous nature of AJAX

    - by Anurag
    How would I design an API to hide the asynchronous nature of AJAX and HTTP requests, or basically delay it to provide a fluid interface. To show an example from Twitter's new Anywhere API: // get @ded's first 20 statuses, filter only the tweets that // mention photography, and render each into an HTML element T.User.find('ded').timeline().first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); function filterer(status) { return status.text.match(/photography/); } vs this (asynchronous nature of each call is clearly visible) T.User.find('ded', function(user) { user.timeline(function(statuses) { statuses.first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); }); }); It finds the user, gets their tweet timeline, filters only the first 20 tweets, applies a custom filter, and ultimately uses the callback function to process each tweet. I am guessing that a well designed API like this should work like a query builder (think ORMs) where each function call builds the query (HTTP URL in this case), until it hits a looping function such as each/map/etc., the HTTP call is made and the passed in function becomes the callback. An easy development route would be to make each AJAX call synchronous, but that's probably not the best solution. I am interested in figuring out a way to make it asynchronous, and still hide the asynchronous nature of AJAX.

  • Node.js running under IIS Express Keeps Crashing

    - by PazoozaTest Pazman
    I recently resinstalled Windows 7 on my machine and went back to downloading and installing the tools to help me continue developing node.js windows azure web applications. I followed the instructions given on the node.js azure site: http://www.windowsazure.com/en-us/develop/nodejs/ and using web installer 4.0 it says I have successfully installed these tools: Windows Azure Powershell Windows Azure SDK for Node.js - June 2012 Windows Azure SDK for .Net (VS 2012 RC) - June 2012 IIS Recommend Configuration The problem I am experiencing is that when I run the site using powershell e.g: start-azureemulator -launch it goes ahead and runs IIS Express, and after several minutes IIS Express crashes with the following information: Problem signature: Problem Event Name: APPCRASH Application Name: iisexpress.exe Application Version: 8.0.8298.0 Application Timestamp: 4f620349 Fault Module Name: iiscore.dll Fault Module Version: 8.0.8298.0 Fault Module Timestamp: 4f63b65c Exception Code: c0000005 Exception Offset: 00021767 OS Version: 6.1.7601.2.1.0.256.28 Locale ID: 1033 Additional Information 1: f66d Additional Information 2: f66d807b515d6b2dc6f28f66db769a01 Additional Information 3: 7b2f Additional Information 4: 7b2f6797d07ebc2c23f2b227e779722e I am running 2 instances each time, and both of them crash one after the other. Is anyone experiencing something similar and fix this issue ? Is their an upgrade I need to do ? I've run windows update but it says I've got all the latest updates etc. Can I tell the powershell cmdlet to use IIS 7 instead of IIS Express? I'm guessing its something to do with IIS Express on my machine. I did some hunting around and found this person here who experienced a similar problem: https://github.com/tjanczuk/iisnode/issues/149 I've got a cron job running every 1 second, to check if any website totals need to be updated. Could this be causing IIS Express to crash? Cheers

  • DRY Authenticated Tasks in Cocoa (with distributed objects)

    - by arbales
    I'm kind of surprise/infuriated that the only way for me to run an authenticated task, like perhaps sudo gem install shi*t, is to make a tool with pre-written code. I'm writing a MacRuby application, which doesn't seem to expose the KAuthorization* constants/methods. So.. I learned Cocoa and Objective-C. My application creates a object, serves it and calls the a tool that elevates itself and then performs a selector on a distributed object (in the tool's thread). I hoped that the distributed object's methods would evaluated inside the tool, so I could use delegation to create "privileged" tasks. If this won't work, don't try to save it, I just want a DRY/cocoa solution. AuthHelper.m //AuthorizationExecuteWithPrivileges of this. AuthResponder* my_responder = [AuthResponder sharedResponder]; // Gets the proxy object (and it's delegate) NSString *selector = [NSString stringWithUTF8String:argv[3]]; NSLog(@"Performing selector: %@", selector); setuid(0); if ([[my_responder delegate] respondsToSelector:NSSelectorFromString(selector)]){ [[my_responder delegate] performSelectorOnMainThread:NSSelectorFromString(selector) withObject:nil waitUntilDone:YES]; } RandomController.m - (void)awakeFromNib { helperToolPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingString:@"/AuthHelper"]; delegatePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingString:@"/ABExtensions.rb"]; AuthResponder* my_responder = [AuthResponder initAsService]; [my_responder setDelegate:self]; } -(oneway void)install_gems{ NSArray *args = [NSArray arrayWithObjects: @"gem", @"install", @"sinatra", nil]; [NSTask launchedTaskWithLaunchPath:@"/usr/bin/sudo" arguments:args]; NSLog(@"Ran AuthResponder.delegate.install_gems"); // This prints. } ... other privileges tasks. "sudo gem update --system" for one. I'm guessing the proxy object is performing the selector in it's own thread, but I want the current (privileged thread) to do it so I can use sudo. Can I force the distributed object to evaluate the selector on the tool's thread? How else can I accomplish this dryly/cocoaly?

    Hi All, I've begun playing with the android NDK. One of the things I've just learnt is about creating an application.mk file to specify the armv7 abi. I'm building the san-angeles example with the following parameters. APP_MODULES := sanangeles APP_PROJECT_PATH := $(call my-dir)/../ APP_OPTIM := release APP_ABI := armeabi-v7a However this seems to run at exactly the same speed as it did before (ie badly). Am I just GL limited and not CPU limited or is something wrong here? I have noticed when I compile that I get the following command line options emitted: -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -mthumb The thing that worries me there is the "softfp". There IS mention of the v7 abi, the VFP fpu stuff and I'm guessing the "thumb" refers to the "thumb-2" instructions (Though I don't know what exactly these are). However that "softfp" does concern me. Shouldn't it be "hardfp"? Anyone got any ideas on these questions? I think I'm probably about ready to start implementing some GL ES 2.0 code for my HTC Desire but I'd like to make sure I'm getting the best possible speed out of it :) Cheers in advance!

  • PHP Performance Metrics

    - by bigstylee
    I am currently developing a PHP MVC Framework for a personal project. While I am developing the framework I am interested to see any notable performance by implementing different techniques for optimization. I have implemented a crude BenchMark class that logs mircotime. The problem is I have no frame of reference for execution times. I am very near the beginnig of this project with a database connection and a few queries but no output (bar some debugging text and BenchMark log). I have a current execution time of 0.01917 seconds. I was expecting this to be lower but as I said before I have no frame of reference. I appreciate there are many variables to take into account when juding performance but I am hoping to find some sort of metric to a) techniques to measure performance for example requests per second and b) compare results for example; how a "moderately" sized PHP application on a "standard" webserver will perform. I appreciate "moderately" and "standard" are very subjective words so perhaps a table of known execution times for a particular application (eg StackOverFlow's executing time). What are other techniques of measuring performance are there other than execution time? When looking at MVC Framework Performance Comparisom it talks about Requests Per Second (RPS). How is this calculated? I am guessing with my current execution time of 0.01917 seconds can handle 52 RPS (= 1 / 0.01917 ). This seems to be significantly lower than that quoted on the graph especially when you consider my current limited funcitonality.

  • PageMethod with Custom Handler

    - by Mister Cook
    I have a page based web method which works fine, using [WebMethod], i.e [WebMethod] public static void DoSomethingOnTheServer() { } I also have a custom page handler to make SEO friendly URLs possible, e.g http://localhost/MySite/A_nice_url.ext = http://localhost/MySite/page.aspx?id=1 I am using Server.Transfer in my ProcessRequest handler to achieve this. This all works fine. Also, my page method works fine when the user requests the URL such as: http://localhost/MySite/page.aspx?id=1 However, when the user requests the custom handled URL, i.e. http://localhost/MySite/A_nice_url.ext The client reports that the PageMethod has been successfully completed, but it has not been called at all. I'm guessing it has something to do with my custom handler, so I have modified it to include PathInfo: public void ProcessRequest(HttpContext context) { // ... (code to determine id) ... // Transfer to the required page string actualPath = "~/page.aspx" + context.Request.PathInfo + "?id=" + determinedId; context.Server.Transfer(actualPath); } So now if a PageMethod is called, it will result in: http://localhost/MySite/page.aspx/DoSomethingOnTheServer?id=1 I'm wondering if this is the correct syntax for calling a PageMethod. When I try Server.Transfer reports: Error executing child request for /MySite/page.aspx/DoSomethingOnTheServer I've experimented with HttpContext.RewritePath but not sure how to actually make it perform the request. This does not seem to work, any ideas?

  • Django tests failing on invalid keyword argument

    - by Darwin Tech
    I have a models.py like so: from django.db import models from django.contrib.auth.models import User from datetime import datetime class UserProfile(models.Model): user = models.OneToOneField(User) def __unicode__(self): return self.user.username class Project(models.Model): user = models.ForeignKey(UserProfile) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) product = models.ForeignKey('tool.product') module = models.ForeignKey('tool.module') model = models.ForeignKey('tool.model') zipcode = models.IntegerField(max_length=5) def __unicode__(self): return unicode(self.id) And my tests.py: from django.test import TestCase, Client # --- import app models from django.contrib.auth.models import User from tool.models import Module, Model, Product from user_profile.models import Project, UserProfile # --- unit tests --- # class UserProjectTests(TestCase): fixtures = ['admin_user.json'] def setUp(self): self.product1 = Product.objects.create( name='bar', ) self.module1 = Module.objects.create( name='foo', enable=True ) self.model1 = Model.objects.create( module=self.module1, name='baz', enable=True ) self.user1 = User.objects.get(pk=1) ... def test_can_create_project(self): self.project1 = Model.objects.create( user=self.user1, product=self.product1, module=self.module1, model=self.model1, zipcode=90210 ) self.assertEquals(self.project1.zipcode, 90210) But I get a TypeError: 'product' is an invalid keyword argument for this function error. I'm not sure what is failing but I'm guessing something to do with the FK relationships... Any help would be much appreciated.

  • WPF Textbox & Borders - curious resizing behavior

    - by CitizenParker
    The following XAML produces a window with strange behavior around the textbox: <Window x:Class="WpfSandbox.CuriousExample" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="CuriousExample" Height="300" Width="300"> <DockPanel Margin="15"> <TextBox BorderThickness="1" BorderBrush="#FF000000"></TextBox> </DockPanel> </Window> What happens, at least during my limited testing, is that the textbox renders with an inset border pattern (top/left is black, right/bottom is grey). However, when you resize to any position except the original, the entire textbox border goes to black. Whenever you return the window to the exact number of on-screen pixels the form had when it first loaded, it's inset again. I'm guessing it isn't pixel snapping as I can easily correct the problem with this code: <Window x:Class="WpfSandbox.CuriousExample" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="CuriousExample" Height="300" Width="300"> <DockPanel Margin="15"> <Border BorderThickness="1" BorderBrush="#FF000000"> <TextBox BorderThickness="0" ></TextBox> </Border> </DockPanel> </Window> Anyone care to venture an explanation as to what I'm seeing? Or is it all in my head? Like I said, the above workaround can resolve this problem - just trying to understand what is happening here. Thanks, -Scott
