• Deploying site on Amazon Beantalk and IIS settings

  - by Idan Shechter

  I am interested in working with Amazon Elastic Beantalk to deploy my new site. A few things that I need to know and can't get an answer to: 1) How can I maintain IIS settings of all deployed and future deployed machines? 2) If I can maintain, what happens if I change the settings on one server, will it automatically set it on other servers? 3) How can I backup the data. In other servers I usually make an AMI and deploy to a new server in case of a problem?

• Problem setText UITextView

  - by Mat

  Hi i have a problem. I have 2 viewcontroller, in the first there is a mapView that implements the function "calloutAccessoryControlTapped" to tap a button on an annotation on the mapView; in the second there is just a UITextView. I want to change the text of the UITextView (and show the SecondViewController) in the second controller once the button on annotation is clicked; here is my code (FirstViewController) Header @interface FirstViewController<MKMapViewDelegate>{ IBOutlet MKMapView *mapView; SecondViewController *secondV;} @end Implementation @implementation FirstViewController - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control{ secondV = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; NSString *myS = @"some text here"; [secondV.myTextView setText:myS]; //Switch from this to the secondview [self presentModalViewController:secondV animated:YES]; @end (SecondViewController) Header @interface SecondViewController{ IBOutlet UITextView *myTextView; } @property(nonatomic, retain)UITextView *postitTextView; - (IBAction)backToMAp; - (void)setText:(NSString *)string; @end Implementation @implementation SecondViewController - (IBAction)backToMAp{ //Back To First View; [self dismissModalViewControllerAnimated:YES];} - (void)setText:(NSString *)string{ myTextView.text = string;} In this code when i tap on the button ([self presentModalViewController:secondV animated:YES];) on annotation the first time the second view show up but the text of UITextView don't change, when i back on the FirstView ([self dismissModalViewControllerAnimated:YES];) and then again tap the button to switch again to secondView the text of UITextView change..... Sorry for long thread and for my bad english!! Thank you stack!

• Record/Playback with AudioQueue on iPhone

  - by Biranchi

  Hi, I am currently using Audio Queues on the iPhone to record and playback audio. What I would like to be able to do is to record some audio, allow the user to pause the record queue, and to seek back and forward through the audio to select a position from where they can start recording from again. I have got over the seeking issue by making the playback AudioQueueBuffer sizes small enough so that the play audio queue callback happens at a rate that allows the user to use a slider control to hear the audio as they adjust the slider back and forth. I think I can achieve the recording at a new position by setting the inStartingPacket parameter of the AudioFileWritePackets function that I call from the Audio Recording Queue callback. The trouble is this only inserts audio over the previously recorded audio. The file length obviously doesn't change so if the user were to go backwards and record less audio than before, the old audio still remains after the end of the newly recorded audio. Is there a way I can get the AudioFile to truncate at the point the user starts to insert the new audio, is there some other way I can remove the old audio starting at the insert position or is there a better way about going about this task? Thanks

• Getting browser to make an AJAX call ASAP, while page is still loading

  - by Chris

  I'm looking for tips on how to get the browser to kick off an AJAX call as soon as possible into processing a web page, ideally before the page is fully downloaded. Here's my approximate motivation: I have a web page that takes, say, 5 seconds to load. It calls a web service that takes, say, 10 seconds to load. If loading the page and calling the web service happened sequentially, the user would have to wait 15 seconds to see all the information. However, if I can get the web service call started before the 5 second page load is complete, then at least some of the work can happened in parallel. Ideally I'd like as much of the work to happen in parallel as possible. My initial theory was that I should place the AJAX-calling javascript as high up as possible in the web page HTML source (being mindful of putting it after the jquery.js include, because I'm making the call using jquery ajax). I'm also being mindful not to wrap the AJAX call in a jquery ready event handler. (I mention this because ready events are popular in a lot of jquery example code.) However, the AJAX call still doesn't seem to get kicked off as early as I'm hoping (at least as judged by the Google Chrome "Timeline" feature), so I'm wondering what other considerations apply. One thing that might potentially be detrimental is that the AJAX call is back to the same web server that's serving the original web page, so I might be in danger of hitting a browser limit on the # of HTTP connections back to that one machine? (The HTML page loads a number of images, css files, etc..)

• Problem with response.redirect sending incorrect HTTPMethod

  - by Andy Macnaughton-Jones

  Hi, I've got a strange problem with a Response.Redirect. I'm using VB.NET with the .NET 2 framework (so VS2005 & SP1). I've got a page that I do a form submit on (that's a proper form method="POST" hard-coded onto the page) and that properly posts me back the page data which is then processed. As part of that processing the system determines if we need to get sent to another URL after processing has been complete. So the request.httpmethod = "POST". So if the "GotoPage" parameter has a URL specified we then do a response.redirect(URL, false). (False as we want page processing to complete in order to write some timing logs etc). The page correctly redirects but instead of the response having a "GET" as the request.httpmethod it has a "POST" instead ! Now, we're using our own custom framework so that we use the HTTPRequest method to determine if a page has been posted back or is being "Getted" so the "IsPagePostBack" property doesn't work (that only works when you're using the normal .NET controls and form submissions). In all other instances our code works happily but what might be causing the Request.httpMethod to not be being set correctly ? I've tried doing a response.clear before the redirect in case headers are being written out before hand but to no avail. Any clues ?! thanks, Andy

• Find which php scripts cause high CPU with php-cgi

  - by Oli

  Background: I maintain a server for a client who has half a dozen Wordpress sites on. They all have the W3 Total Cache plugin installed and eAcellerator is installed (might be APC). All the PHP sites run through a single batch of fastcgi php-cgi processes (it's actually php-fpm but I'm not sure if that makes a difference). Problem: php-cgi's CPU usage is quite high. Not terminally high but high enough to raise an eyebrow. The client wants to add more sites in the future and I want to avoid becoming CPU limited if I can help it. Question: Is there any way I can find the scripts or even just requests that are causing the high CPU. I realise I might not be able to do anything with the results but it would give me a chance.

• iPad + OpenGL ES2. Why the Puzzling Virtual Memory Spike During Device Reorientation?

  - by dugla

  I've been spending the afternoon starring at Xcode Instruments memory monitor trying to decipher the following memory issue. I have a fullscreen OpenGL ES2 app running on iPad. I am fanatical about memory issues so my retains/releases are all nicely balanced. I closely monitor memory leaks. My app is basically squeeky clean. Except occassionally when I reorient the device. Portrait to Landscape. Back and forth I rock the device stress testing my discarding and rebuilding of the OpenGL framebuffer. The ambient memory footprint of my app is about 70MB Real Mems and 180MB Virtual Mems. Real memory hardly varies at all during device rotations. However the virtual mems reading sometimes briefly spikes up to 250MB and then recedes back to 180MB. No real pattern. But clearly related discarding/rebuilding the framebuffer. I see random memory warnings in my NSlogs but the app just hums along, no worries. 1) Since iPhone OS devices don't have VM could someone explain to me what the VM reading actually means? 2) My app totally leak free and generally bulletproof dispite the VM spikes. Never crashes. Rock solid. Should I be concerned about this? 3) There is clearly something happening in OpenGL framebuffer land that is causing this but I am using the API in the proper way: paraphrasing: Discarding the framebuffer: glDeleteRenderbuffers(1, &m_colorbuffer); glDeleteFramebuffers(1, &m_framebuffer); Rebuilding the framebuffer: glGenFramebuffers(1, &m_framebuffer); glGenRenderbuffers(1, &m_colorbuffer); Is there some other memory flushing trick I have missed? Thanks for any insight. Cheers, Doug

• Does any upgrade version of Visual Studio require an installed development tool?

  - by Will Eddins

  I'm wondering this from a legal standpoint and an installation-issue standpoint. I'm considering pre-ordering Visual Studio 2010 for future use in some home projects, and you cannot pre-order a full version, only an upgrade version. On the preorder page, it says: Eligible for upgrade with any previous version of Visual Studio or any other developer tool. In reality, I think it won't require anything installed, but from a legal standpoint, is this inclusive with development tools such as Eclipse? After installing Windows 7 on this PC, Eclipse is currently the only IDE I have installed. But really anything could be considered a developer tool, such as Notepad++ or Kaxaml. How has this worked in regards to previous upgrade versions?

• How do I reset the scale/zoom of a web app on an orientation change on the iPhone?

  - by Elisabeth

  I'm having the same problem that a couple of others have had with getting the correct behavior in a web app on an orientation change, and there doesn't seem to be an obvious solution - I've seen this question asked a couple of times on Stack Overflow and no one's yet been able to answer it. When I start the app in portrait mode, it works fine. Then I rotate into landscape and it's scaled up. To get it to scale correctly for the landscape mode I have to double tap on something twice, first to zoom all the way in (the normal double tap behavior) and again to zoom all the way out (again, the normal double tap behavior). When it zooms out, it zooms out to the correct NEW scale for landscape mode. Switching back to portrait seems to work more consistently; that is, it handles the zoom so that the scale is correct when the orientation changes back to portrait. I am trying to figure out if this is a bug? or if this is something that can be fixed with Javascript? With the viewport meta content, I am setting the initial-scale to 1.0 and I am NOT setting minimum or maximum scale (nor do I want to). I am setting the width to device-width. Any ideas? I know a lot of people would be grateful to have a solution as it seems to be a persistent problem. Thank you!

• can 'Percona MySQL Data Recovery' be used to recover dropped tables if the datadir filesystem is mounted as /

  - by Tom Geee

  according to Percona: Unmount the filesystem or make it read-only if... You have filesystem corruption OR You have dropped tables in innodb_file_per_table format If I have innodb_file_per_table enabled, and accidently dropped a table, while the datadir is mounted as within the / partition , can data still be recovered? Obviously you can't work with an unmounted root filesystem. Our VPS host has a defaulted filesystem table which we cannot customize. I was wondering in case of any future scenario. edit: would mounting the / filesystem through NFS onto another system as read-only be a workaround? TIA.

• Detection of page refresh / F5 key in ASP.NET MVC 2

  - by Michael

  How would one go about detecting a page refresh / F5 key push on the controller handling the postback? I need to distinguish between the user pressing one of two buttons (e.g., Next, Previous) and when the F5 / page refresh occurs. My scenario is a single wizard page that has different content shown between each invocation of the user pressing the "Next" or "Previous" buttons. The error that I am running into is when the user refreshes the page / presses the F5 key, the browser re-sends the request back to the controller, which is handled as a post-back and the FormCollection type is used to look for the "submitButton" key and obtain its value (e.g., "Next," "Send"). This part was modeled after the post by Dylan Beattie at http://stackoverflow.com/questions/442704/how-do-you-handle-multiple-submit-buttons-in-asp-net-mvc-framework. Maybe I'm trying to bend MVC 2 to where it isn't meant to go but I'd like to stay with the current design in that the underlying database drives the content and order of what is shown. This allows us to add new content into the database without modifying the code the displays the content. Thanks, Michael

• How have you successfully implemented MessageBox.Show() functionality in MVVM?

  - by Edward Tanguay

  I've got a WPF application which calls MessageBox.Show() way back in the ViewModel (to check if the user really wants to delete). This actually works, but goes against the grain of MVVM since the ViewModel should not explicitly determine what happens on the View. So now I am thinking how can I best implement the MessageBox.Show() functionality in my MVVM application, options: I could have a message with the text "Are you sure...?" along with two buttons Yes and No all in a Border in my XAML, and create a trigger on the template so that it is collapsed/visible based on a ViewModelProperty called AreYourSureDialogueBoxIsVisible, and then when I need this dialogue box, assign AreYourSureDialogueBoxIsVisible to "true", and also handle the two buttons via DelegateCommand back in my ViewModel. I could also somehow try to handle this with triggers in XAML so that the Delete button actually just makes some Border element appear with the message and buttons in it, and the Yes button did the actually deleting. Both solutions seem to be too complex for what used to be a couple lines of code with MessageBox.Show(). In what ways have you successfully implemented Dialogue Boxes in your MVVM applications?

• MySQL: creating a user that can connect from multiple hosts

  - by DrStalker

  I'm using MySQL and I need to create an account that can connect from either the localhost of from another server, 10.1.1.1. So I am doing: CREATE USER 'bob'@'localhost' IDENTIFIED BY 'password123'; CREATE USER 'bob'@'10.1.1.1 IDENTIFIED BY 'password123'; GRANT SELECT, INSERT, UPDATE, DELETE on MyDatabse.* to 'bob'@'localhost', 'bob'@'10.1.1.1; This works fine, but is there any more elegant way to create a user account that is linked to multiple IPs or does it need to be done this way? My main worry is that in the future permissions will be updated form 'bob' account and not the other.

• IPhone custom UITableViewCell Reloading

  - by Steblo

  Hi, currently I'm struggling with this problem: I got a UITableViewController that displays a tableView with different custom cells. One custom cell displays a number (by a label). If you click on this cell, the navigationController moves to a UIPicker where the user can select the number to be displayes. If the user moves back, the cell should display the updated value. Problem: I managed to reload the cells by calling - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.tableView reloadData]; } in the UITableViewController. This works only, if I don't use dequeueReusableCellWithIdentifier for the cell (tables won't show updates otherwise). But in this case, memory usage grows and grows... In addition, the program crashes after about 15 movements to pickerView and back - I think because the cell that should be reloaded is already released. How can I update a reusable custom cell every time the view appears ? What is the best solution ? I think retaining cells should not be used ?

• How to route HyperV VMs traffic through host VPN

  - by Random

  I'm using Windows 8.1 Pro with HyperV. I have several VMs for development, all of them connected with host via Internal adapter using network addresses: 192.168.10.0/24 Where: 192.168.10.1 is my host's Hyper-V internal NIC address. When I'm not in my office I use 3G usb dongle an dialup VPN connection. I would like to route traffic from all existing and future VMs through the VPN. In best scenario traffic would be routed only partially to the local company network addresses 10.1.1.0/24 I don't want to use sharing because I'm switching between WiFi, USB 3G dongle and VPN. Moving to other virtualization is also not an option for me.

• How to watch 3D on Acer "3D Ready" projector?

  - by glenneroo

  We have here a Acer P1200 DLP projector which is "3D Ready" (using the BrilliantColor™ DarkChip™ 3) and documentation was not included in the packaging. We don't have a Blu-ray player and have no intention of purchasing one in the near future so I'm looking for a way to view encoded or streamed content. My question is: How is it possible to watch 3D content? What extra hardware/software will I need? EDIT: Found this information in the user manual: DLP 3D function: Choose while using DLP 3D glasses, quad buffer (NVIDIA/ATI…) graphic card and HQFS format file or DVD with corresponding SW player. 3D Sync L/R: If you see a discrete or overlapping image while wearing DLP 3D glasses, you may need to execute "Invert" to get best match of left/ right image sequence to get the correct image (for DLP 3D). ...but I'm still at a loss. What is a quad buffer graphics card?

• RFC regarding WAM

  Request For Comment regarding Whitespace's Assembly Mnemonics What follows in a first generation attempt at creating mnemonics for a whitespace assembly language. STACK ===== push number copy copy number swap away away number MATH ==== add sub mul div mod HEAP ==== set get FLOW ==== part label call label goto label zero label less label back exit I/O === ochr oint ichr iint In the interest of making improvements to this small and simple instruction set, this is a second attempt. hold N Push the number onto the stack copy Duplicate the top item on the stack copy N Copy the nth item on the stack (given by the argument) onto the top of the stack swap Swap the top two items on the stack drop Discard the top item on the stack drop N Slide n items off the stack, keeping the top item add Addition sub Subtraction mul Multiplication div Integer Division mod Modulo save Store load Retrieve L: Mark a location in the program call L Call a subroutine goto L Jump unconditionally to a label if=0 L Jump to a label if the top of the stack is zero if<0 L Jump to a label if the top of the stack is negative return End a subroutine and transfer control back to the caller exit End the program print chr Output the character at the top of the stack print int Output the number at the top of the stack input chr Read a character and place it in the location given by the top of the stack input int Read a number and place it in the location given by the top of the stack What do you think of the following revised list for Whitespace's assembly instructions? I'm still thinking outside of the box somewhat and trying to come up with a better mnemonic set than last time. When the previous interpreter was written, it was completed over two contiguous, rushed evenings. This rewrite deserves significantly more time now that it is the summer. Of course, the next version of Whitespace (0.4) may have its instructions revised even more, but this is just a redesign of what originally was done in a very short amount of time. Hopefully, the instructions make more sense once someone new to programmings thinks about them.

• Synchronize DataGrid and DataForm in Silverlight 3

  - by SpiralGray

  I've been banging my head against the wall for a couple of days on this and it's time to ask for help. I've got a DataGrid and DataForm on the same UserControl. I'm using an MVVM approach so there is a single ViewModel for the UserControl. That ViewModel has a couple of properties that are relevant to this discussion: public ObservableCollection<VehicleViewModel> Vehicles { get; private set; } public VehicleViewModel SelectedVehicle { get { return selectedVehicle; } private set { selectedVehicle = value; OnPropertyChanged( "SelectedVehicle" ); } } In the XAML I've got the DataGrid and DataForm defined as follows: <data:DataGrid SelectionMode="Single" ItemsSource="{Binding Vehicles}" SelectedItem="{Binding SelectedVehicle, Mode=TwoWay}" AutoGenerateColumns="False" IsReadOnly="True"> <dataFormToolkit:DataForm CurrentItem="{Binding SelectedVehicle}" /> So as the SelectedItem changes on the DataGrid it should push that change back to the ViewModel and when the ViewModel raises the OnPropertyChanged the DataForm should refresh itself with the information for the newly-selected VehicleViewModel. However, the setter for SelectedVehicle is never being called and in the Output window of VS I'm seeing the following error: System.Windows.Data Error: ConvertBack cannot convert value 'xxxx.ViewModel.VehicleViewModel' (type 'xxxx.ViewModel.VehicleViewModel'). BindingExpression: Path='SelectedVehicle' DataItem='xxxx.ViewModel.MainViewModel' (HashCode=31664161); target element is 'System.Windows.Controls.DataGrid' (Name=''); target property is 'SelectedItem' (type 'System.Object').. System.MethodAccessException: xxxx.ViewModel.MainViewModel.set_SelectedVehicle(xxxx.ViewModel.VehicleViewModel) It sounds like it's having a problem converting from a VehicleViewModel to an object (or back again), but I'm confused as to why that would be (or even if I'm on the right track with that assumption). Each row/item in the DataGrid should be a VehicleViewModel (because the ItemsSource is bound to an ObservableCollection of that type), so when the SelectedItem changes it should be dealing with an instance of VehicleViewModel. Any insight would be appreciated.

• ASP.NET MVC 2: Mechanics behind an Order / Order Line in a edit form

  - by Dr. Zim

  In this question I am looking for links/code to handle an IList<OrderLine> in an MVC 2 edit form. Specifically I am interested in sending a complete order to the client, then posting the edited order back to an object (to persist) using: Html.EditorFor(m = m.orderlines[i]) (where orderlines is an enumerable object) Editing an Order that has multiple order lines (two tables, Order and OrderLine, one to many) is apparently difficult. Is there any links/examples/patterns out there to advise how to create this form that edits an entity and related entities in a single form (in C# MVC 2)? The IList is really throwing me for a loop. Should I have it there (while still having one form to edit one order)? How could you use the server side factory to create a blank OrderLine in the form while not posting the entire form back to the server? I am hoping we don't treat the individual order lines with individual save buttons, deletes, etc. (for example, they may open an order, delete all the lines, then click cancel, which shouldn't have altered the order itself in either the repository nor the database. Example classes: public class ViewModel { public Order order {get;set;} // Only one order } public class Order { public int ID {get;set;} // Order Identity public string name {get;set;} public IList<OrderLine> orderlines {get;set;} // Order has multiple lines } public class OrderLine { public int orderID {get;set;} // references Order ID above public int orderLineID {get;set;} // Order Line identity (need?) public Product refProduct {get;set;} // Product value object public int quantity {get;set;} // How many we want public double price {get;set;} // Current sale price }

• MySQL started to consume about 40% of system CPU time and got unresponsive suddenly

  - by Alex

  I use Debian 6.0.3 x86_64 and MySQL 5.5.20-1~dotdeb.0-log from the Dotdeb repository. MySQL process started to consume a lot of "sy" CPU time serveral hours ago according to this graph. I was not able to connect to running mysqld process and had to kill it. I found nothing useful in logs. My setup seems to be quite common (I assume Dotdeb just redistributes stock MySQL versions) and I have never seen anything like this before. What is the possible root cause of this? How can I prevent this situation in the future?

• WCF Double Hop questions about Security and Binding.

  - by Ken Maglio

  Background information: .Net Website which calls a service (aka external service) facade on an app server in the DMZ. This external service then calls the internal service which is on our internal app server. From there that internal service calls a stored procedure (Linq to SQL Classes), and passes the serialized data back though to the external service, and from there back to the website. We've done this so any communication goes through an external layer (our external app server) and allows interoperability; we access our data just like our clients consuming our services. We've gotten to the point in our development where we have completed the system and it all works, the double hop acts as it should. However now we are working on securing the entire process. We are looking at using TransportWithMessageCredentials. We want to have WS2007HttpBinding for the external for interoperability, but then netTCPBinding for the bridge through the firewall for security and speed. Questions: If we choose WS2007HttpBinding as the external services binding, and netTCPBinding for the internal service is this possible? I know WS-* supports this as does netTCP, however do they play nice when passing credential information like user/pass? If we go to Kerberos, will this impact anything? We may want to do impersonation in the future. If you can when you answer post any reference links about why you're answering the way you are, that would be very helpful to us. Thanks!

• C++: Check istream has non-space, non-tab, non-newline characters left without extracting chars

  - by KRao

  I am reading a std::istream and I need to verify without extracting characters that: 1) The stream is not "empty", i.e. that trying to read a char will not result in an fail state (solved by using peek() member function and checking fail state, then setting back to original state) 2) That among the characters left there is at least one which is not a space, a tab or a newline char. The reason for this is, is that I am reading text files containing say one int per line, and sometimes there may be extra spaces / new-lines at the end of the file and this causes issues when I try get back the data from the file to a vector of int. A peek(int n) would probably do what I need but I am stuck with its implementation. I know I could just read istream like: while (myInt << myIstream) {...} //Will fail when I am at the end but the same check would fail for a number of different conditions (say I have something which is not an int on some line) and being able to differentiate between the two reading errors (unexpected thing, nothing left) would help me to write more robust code, as I could write: while (something_left(myIstream)) { myInt << myIstream; if (myStream.fail()) {...} //Horrible things happened } Thank you!

• Git-svn branch hoses dcommit when using an odd branch structure

  - by Chuck Vose

  I had a boss, past-tense, who decided to put svn branches in the same folder as trunk. Normally, this wouldn't affect me that much but since I'm using git-svn things are going so well. After I did a fetch it created a folder for each branch in my root folder so I have three folders, drupal, trunk, and client. The drupal folder is git's master branch, client and trunk are the svn branches. Merging and committing works great, in fact everything git related is working superb. However dcommit is totally hosed, it's trying to commit a folder called client and one called trunk. I can't even imagine what havoc this would cause for svn later on. So my question is, what have I done wrong in my .git/config and is there anything I can do to fix this or am I going to have to suffer and go back to using svn? Please don't make me go back. I don't think I can take it anymore. Bastard boss knows how to leave a legacy. [svn-remote "svn"] url = https://svn.mydomain.com/svn/project_name fetch = trunk:refs/remotes/trunk branches = *:refs/remotes/* tags = tags/*:refs/remotes/tags/* Normally the branches line would look like this (when using --stdlayout): branches = branches/*:refs/remotes/branches/* ls output is thus: $ ls client/ docs/ drupal/ sql/ trunk/

• Perl script and out of memory errors

  - by Kevin

  We have a midsized server with 48GB of RAM and are attempting to import a list of around 100,000 opt-in email subscribers to a new list management system written in Perl. From my understanding, Perl doesn't have imposed memory limits like PHP, and yet we are continuously getting internal server errors when attempting to do the import. When investigating the error logs, we see that the script ran out of memory. Since perl doesn't have a setting to limit the memory usage (as far as I can tell) why are we getting these errors? I doubt a small import like this is consuming 48GB of ram. We have compromised and split the list into chunks of 10,000, but would like to figure out the root cause for future fixes. This is a CentOS machine with Litespeed as the web server.

• Flash video slooow in AIR 2 HTMLLoader component

  - by shane

  I am working on a full screen kiosk application in Flex 4/Air 2 using Flash Builder 4. We have a company training website which staff can access via the kiosk, and the main content is interactive flash training videos. Our target machines are by no means 'beefy', they are Atom n270s @ 1.6Ghz with 1Gb RAM. As it stands the videos are all but unusable when used from within the Air application, the application becomes completely unresponsive (100% cpu usage, click events take approx 5-10 seconds to register). So far I have tried: increasing the default frame rate from 24fps to 60. No improvement. nativeWindow.stage.frameRate = 60; running the videos in a stripped down version of my app, just a full screen HTMLLoader component pointed at the training website. No better than before. disabled hyper threading. The Atom CPU is split into two virtual cores, and the AIR app was only able to use one thread so maxed out at 50% CPU usage. Since the kiosk will only run the AIR app I am happy to loose hyper threading to increase the performance of the Air app. Marginal Improvement. The same website with the same videos is responsive if viewed in ie7 on the same machine, although Internet Explorer takes advantage of the CPU’s hyper threading. The flash videos are built with Adobe Captivate and from what I understand employee JavaScript to relay results back to the server. I will add more information about the video content asap as the training guru is back in the office later this week.
