• iPhone/iPad universal build problem with firmware version

  - by DigitalVanilla

  Hello guys, I was doing a project as Universal binary for iPhone/iPad. I created the iPhone app side and I was doing to complete the iPad too. I noticed one thing, on iPad classes I use the UIPopoverController class, means that when I build now for 3.2 in the Simulator, it runs te iPad one and it works fine, BUT if I want to see the iPhone version app, means 3.1.3, It give me an error of framework missing in the iPad classes. I have no idea how to solve this problem because I cannot anymore see the iPhone version of the app and make changes. I can only remove all the iPad classes and after reimport again. thanks guys!

• Writing a plist

  - by iOS-Newbie

  I am trying to test out writing a dictionary to a plist. The following code does not report any errors, but I cannot find any trace of the file that I supposed wrote. Here is the code snippet: NSDictionary *myDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @"First letter of the alphabet", @"A", @"Second letter of the alphabet", @"B", @"Third letter of the alphabet", @"C", nil ]; I can see the dictionary contents displayed properly with either method calls: NSLog(@"Here is my partial dictionary %@", myDictionary); for (NSString *key in myDictionary) NSLog(@"here it is again %@ %@", key, [myDictionary objectForKey:key]); The following code displays the "succeeded" message when the program is run repeatedly if ([myDictionary writeToFile: @"myDictionary" atomically:YES ] == NO) NSLog(@"write to file failed"); else NSLog(@"write to file succeeded"); even when changing the atomically: argument to NO to not write a temporary file. However, when I search my current directory, or even my entire Mac, I cannot find any file called "myDictionary.plist" or any file with the string "myDictionary". Isn't the path variable "@myDictionary" supposed to represent the file at the current directory, i.e. where the class executable resides?

• Commercial CMS on Google App Engine, violation of terms?

  - by Yaggo

  I'm developing commercial CMS running on Google App Engine. I'm thinking of selling it in two ways: 1) Software as a service (SaS). The CMS running in my App Engine account (as single app), hosting the sites of all customers. A turn-key solution for "end user" customers. 2) Licence for running the CMS in customer's own App Engine account. Targeted for digital agencies for reselling as SaS. Being not a lawyer myself, I don't trust my abilities to read between the lines of TOS jargon. Counting on the general knowledge of SO community, my question is: do the above scenarios violate the App Engine Terms of Service?

• Automatically "upgrade" user settings from previous version of app.config file?

  - by SqlRyan

  Every time I compile my app and the version number changes (I have an auto-incrementing build number), I lose the user-configured app.config settings, since they're stored in the AppData folder for a specific version. Essentially, every release of my application starts from scratch as far as user settings go. While this is a mild annoyance in development, it raises the question as I approach deployment/release - if I use the app.config to store my user settings, will the user's personalized settings be hosed every time they install a patch that changes the version number of my app? If so, is there an easy way to "upgrade" the settings from the previous release? I know that using HKCU in the registry is another option, but I like the ease of the My.Settings namespace, and I'd like to stay with app.config. Another SO question asks something similar, though the answer doesn't seem that clear. Will setting my MSI so it asks the user to upgrade be enough to preserve these user-level settings?

  I'm trying to return the height of the detailTextLabel in the heightForRowAtIndexPath delegate method. This way my table view cells should be the same height as my detailTextLabel. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; NSString *text = cell.detailTextLabel.text; CGSize size = cell.detailTextLabel.bounds.size; UIFont *font = cell.detailTextLabel.font; CGSize labelSize = [text sizeWithFont:font constrainedToSize:size lineBreakMode:UILineBreakModeWordWrap]; return labelSize.height; } However I'm getting a EXC_BAD_ACCESS on the following line: UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; Wats wrong with the above piece of code?

• How to submit an app that uses an iOS6 feature?

  - by Darren

  I'm ready to submit my app to apple, however it says on the iOS Dev portal that xCode 4.5 cannot be used to submit apps yet, use the public release. xCode 4.4 wont compile my project because I am using -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } which is the new way to support orientation changes. It seems strange with iOS6 round the corner that I cannot submit this. Must I remove this and submit, then resubmit to support iOS6 when they allow it, or has anyone successfully submitted from xCode 4.5 beta 4? Thanks

• Nokia Windows Phone 8 App Collection

  - by Tim Murphy

  I recently upgraded to a Nokia Lumia 920.  Along with it came the availability of a number of Nokia developed apps or apps that Nokia has made available from other developers.  Below is a summary of some of the ones that I have used to this point.  There are quite a few of them so I won’t be covering everything that is available. Nokia Maps I am quite pleased with the accuracy of Nokia Maps and not having to tap the screen for each turn any more.  The information on the screen is quite good as well.  The couple of improvements I would like to see are for the voice directions to include which street or exit you need to use and improve the search accuracy.  Bing maps had much better search results in my opinion. Nokia Drive This one really had me confused when I first setup the phone.  I was driving down the road and suddenly I am getting notification tones, but there were no visual notifications on the phone.  It seems that in their infinite wisdom Nokia thinks I don’t know when I am going over the speed limit and need to be told. ESPN I really liked my ESPN app on Windows Phone 7.5, but I am not getting the type of experience I was looking for out of this app.  While it allows me to pick my favorite teams, but there isn’t a pivot page or panorama page that shows a summary of my favorite teams.  I have also found that the live tile don’t update very often.  Over all I am rather disappointed compared app produced by ESPN. Smart Shoot I really need to get the kids to let me use this on.  I like the concept, but I need to spend more time with it.  The idea how running the camera through a continuous shooting mode and then picking the best is something that I have done with my DSLR and am glad to see it available here. Cinemagraph Here is a fun filter.  It doesn’t have the most accurate editing features, but it is fun to stop certain parts of a scene and let other parts move.  As a test I stopped the traffic on the highway and let the traffic on the frontage road flow.  It makes for a fun effect.  If nothing else it could be great for sending prank animations to your friends. YouSendIt I have only briefly touched this application.  What I don’t understand is why it is needed.  Most of the functionality seems to be similar to SkyDrive and it gives you less storage.  They only feature that seems to differentiate the app is the signature capability. Creative Studio This app has some nice quick edits, but it is not very comprehensive.  I am also not to thrilled with the user experience.  It puts you though an initial color cast series that I’m not sure why it is there.  Discovery of the remaining adjustments isn’t that great.  In the end I found myself wanting Thumbia back. Panorama This is one of the apps that I like.  I found it easy to use as it guides you with a target circle that you center for it to take the next pictures.  It also stitches the images with amazing speed.  The one thing I wish it had was the capability to turn the phone into portrait orientation and do a taller panorama.  Perhaps we will see this in the future. Nokia Music After getting over the missing album art I found that there were a number of missing features with this app as well.  I have a Zune HD and I am used to being able to go through my collection and adding songs, albums or artists to my now playing.  There also doesn’t seem to be a way to manage playlists that I have seen yet.  Other than that the UI is familiar and it give Nokia City Lens Augmented reality is a cool concept, but I still haven’t seen it implemented in a compelling fashion beyond a demo at TED a couple of years ago.  The app still leaves me wanting as well.  It does give an interesting toy.  It gives you the ability to look for general categories and see general direction and clusters of locations.  I think as this concept is better thought out it will become more compelling. Nokia Trailers I don’t know how often I will use this app, but I do like being able to see what movies are being promoted.  I can’t wait for The Hobbit to come out and the trailer was just what the doctor ordered.  I can see coming back to this app from time to time. PhotoBeamer PhotoBeamer is a strange beast that needs a better instruction manual.  It seems a lot like magic but very confusing.  I need some more testing, but I don’t think this is something that most people are going to understand quickly and may give up before getting it to work.  I may put an update here after playing with it further. Ringtone Maker The app was just published and it didn’t work very well for me. It couldn’t find 95% of the songs that Nokia Music was playing for me and crashed several times.  It also had songs named wrong that when I checked them in Nokia Music they were fine.  This app looks like it has a long way to go. Summary In all I think that Nokia is offering a well rounded set of initial applications that can get any new owner started.  There is definitely room for improvement in all of these apps.  The main need is usability upgrades.  I would guess that with feedback from users they will come up to acceptable levels.  Try them out and see if you agree. del.icio.us Tags: Windows Phone,Nokia,Lumia,Nokia Apps,ESPN,PhotoBeamer,City Lens,YouSendIt,Drive,Maps

• Can I change the "From" name and address without going into Mail.app's preferences?

  - by Arjan van Bentem

  Can I somehow add an editable "From" field to Mail.app, a bit like Virtual Identity for Thunderbird, just like I could change the "Reply To" address on the fly? In Mail.app, one can set up multiple email addresses for a single account by just entering a comma-seperated list like [email protected], [email protected]. Next, when composing a message, Mail offers a dropdown to select a "From" address. And when replying†, it automatically selects the right address if it can find a match: Nice, but I'd like to be able to change the "From" on the fly, without going into the Account Information. Also, in previous versions of Mail one could even specify multiple Full Names for a single account: Email Address: Arjan <[email protected]>, Arjan on SU <[email protected]> But nowadays, Mail only uses the setting of Full Name, and even ignores names in the Email Address field when no value for Full Name is set at all. Hence, it would be great if I could change the Full Name on the fly as well. I had no luck finding a plugin for Mail yet. † When using sub-addressing, anything that is sent to [email protected] is simply delivered to [email protected]. I'd then like to reply with the same full address, rather than just [email protected] if Mail cannot find a match, without going into the Account Information first. I sometimes also want to compose a new message with a new sub-addressing-address.

• Linking a facebook app's page to an existing facebook business page

  - by Dan

  I have a facebook app page, and a separate facebook business profile page. The business page was created, but not by me, some time before the app and its page were created. Is there any way to connect the two pages, or import the content and friends from one to the other? The older profile page has some content; a set of friends and wall posts that I don't want to lose. It was created before I had a chance to set up an app page. Since the app was created more recently, it does not have any content posted to it. I intended the app page to eventually hold some advertising info for my main website itself (non-canvas, just using fb for the connect api etc). The idea being that as people sign up on my site through facebook's OAuth, I could use the graph api to post to their wall. The wall posts are working as expected but naturally they are directing users to the facebook app page, which has no content, friends etc. I'd prefer to be directed to the original business page, where the party is really happening. Now it seems that the two pages are completely separate; what would I need to do to direct the users to the business page?

• Restricting joystick within a radius of center

  - by Phil

  I'm using Unity3d iOs and am using the example joysticks that came with one of the packages. It works fine but the area the joystick moves in is a rectangle which is unintuitive for my type of game. I can figure out how to see if the distance between the center and the current point is too far but I can't figure out how to constrain it to a certain distance without interrupting the finger tracking. Here's the relevant code: using UnityEngine; using System.Collections; public class Boundary { public Vector2 min = Vector2.zero; public Vector2 max = Vector2.zero; } public class Joystick : MonoBehaviour{ static private Joystick[] joysticks; // A static collection of all joysticks static private bool enumeratedJoysticks=false; static private float tapTimeDelta = 0.3f; // Time allowed between taps public bool touchPad; // Is this a TouchPad? public Rect touchZone; public Vector2 deadZone = Vector2.zero; // Control when position is output public bool normalize = false; // Normalize output after the dead-zone? public Vector2 position; // [-1, 1] in x,y public int tapCount; // Current tap count private int lastFingerId = -1; // Finger last used for this joystick private float tapTimeWindow; // How much time there is left for a tap to occur private Vector2 fingerDownPos; private float fingerDownTime; private float firstDeltaTime = 0.5f; private GUITexture gui; // Joystick graphic private Rect defaultRect; // Default position / extents of the joystick graphic private Boundary guiBoundary = new Boundary(); // Boundary for joystick graphic public Vector2 guiTouchOffset; // Offset to apply to touch input private Vector2 guiCenter; // Center of joystick private Vector3 tmpv3; private Rect tmprect; private Color tmpclr; public float allowedDistance; public enum JoystickType { movement, rotation } public JoystickType joystickType; public void Start() { // Cache this component at startup instead of looking up every frame gui = (GUITexture) GetComponent( typeof(GUITexture) ); // Store the default rect for the gui, so we can snap back to it defaultRect = gui.pixelInset; if ( touchPad ) { // If a texture has been assigned, then use the rect ferom the gui as our touchZone if ( gui.texture ) touchZone = gui.pixelInset; } else { // This is an offset for touch input to match with the top left // corner of the GUI guiTouchOffset.x = defaultRect.width * 0.5f; guiTouchOffset.y = defaultRect.height * 0.5f; // Cache the center of the GUI, since it doesn't change guiCenter.x = defaultRect.x + guiTouchOffset.x; guiCenter.y = defaultRect.y + guiTouchOffset.y; // Let's build the GUI boundary, so we can clamp joystick movement guiBoundary.min.x = defaultRect.x - guiTouchOffset.x; guiBoundary.max.x = defaultRect.x + guiTouchOffset.x; guiBoundary.min.y = defaultRect.y - guiTouchOffset.y; guiBoundary.max.y = defaultRect.y + guiTouchOffset.y; } } public void Disable() { gameObject.active = false; enumeratedJoysticks = false; } public void ResetJoystick() { if (joystickType != JoystickType.rotation) { //Don't do anything if turret mode // Release the finger control and set the joystick back to the default position gui.pixelInset = defaultRect; lastFingerId = -1; position = Vector2.zero; fingerDownPos = Vector2.zero; if ( touchPad ){ tmpclr = gui.color; tmpclr.a = 0.025f; gui.color = tmpclr; } } else { //gui.pixelInset = defaultRect; lastFingerId = -1; position = position; fingerDownPos = fingerDownPos; if ( touchPad ){ tmpclr = gui.color; tmpclr.a = 0.025f; gui.color = tmpclr; } } } public bool IsFingerDown() { return (lastFingerId != -1); } public void LatchedFinger( int fingerId ) { // If another joystick has latched this finger, then we must release it if ( lastFingerId == fingerId ) ResetJoystick(); } public void Update() { if ( !enumeratedJoysticks ) { // Collect all joysticks in the game, so we can relay finger latching messages joysticks = (Joystick[]) FindObjectsOfType( typeof(Joystick) ); enumeratedJoysticks = true; } //CHeck if distance is over the allowed amount //Get centerPosition //Get current position //Get distance //If over, don't allow int count = iPhoneInput.touchCount; // Adjust the tap time window while it still available if ( tapTimeWindow > 0 ) tapTimeWindow -= Time.deltaTime; else tapCount = 0; if ( count == 0 ) ResetJoystick(); else { for(int i = 0;i < count; i++) { iPhoneTouch touch = iPhoneInput.GetTouch(i); Vector2 guiTouchPos = touch.position - guiTouchOffset; bool shouldLatchFinger = false; if ( touchPad ) { if ( touchZone.Contains( touch.position ) ) shouldLatchFinger = true; } else if ( gui.HitTest( touch.position ) ) { shouldLatchFinger = true; } // Latch the finger if this is a new touch if ( shouldLatchFinger && ( lastFingerId == -1 || lastFingerId != touch.fingerId ) ) { if ( touchPad ) { tmpclr = gui.color; tmpclr.a = 0.15f; gui.color = tmpclr; lastFingerId = touch.fingerId; fingerDownPos = touch.position; fingerDownTime = Time.time; } lastFingerId = touch.fingerId; // Accumulate taps if it is within the time window if ( tapTimeWindow > 0 ) { tapCount++; print("tap" + tapCount.ToString()); } else { tapCount = 1; print("tap" + tapCount.ToString()); //Tell gameobject that player has tapped turret joystick if (joystickType == JoystickType.rotation) { //TODO: Call! } tapTimeWindow = tapTimeDelta; } // Tell other joysticks we've latched this finger foreach ( Joystick j in joysticks ) { if ( j != this ) j.LatchedFinger( touch.fingerId ); } } if ( lastFingerId == touch.fingerId ) { // Override the tap count with what the iPhone SDK reports if it is greater // This is a workaround, since the iPhone SDK does not currently track taps // for multiple touches if ( touch.tapCount > tapCount ) tapCount = touch.tapCount; if ( touchPad ) { // For a touchpad, let's just set the position directly based on distance from initial touchdown position.x = Mathf.Clamp( ( touch.position.x - fingerDownPos.x ) / ( touchZone.width / 2 ), -1, 1 ); position.y = Mathf.Clamp( ( touch.position.y - fingerDownPos.y ) / ( touchZone.height / 2 ), -1, 1 ); } else { // Change the location of the joystick graphic to match where the touch is tmprect = gui.pixelInset; tmprect.x = Mathf.Clamp( guiTouchPos.x, guiBoundary.min.x, guiBoundary.max.x ); tmprect.y = Mathf.Clamp( guiTouchPos.y, guiBoundary.min.y, guiBoundary.max.y ); //Check distance float distance = Vector2.Distance(new Vector2(defaultRect.x, defaultRect.y), new Vector2(tmprect.x, tmprect.y)); float angle = Vector2.Angle(new Vector2(defaultRect.x, defaultRect.y), new Vector2(tmprect.x, tmprect.y)); if (distance < allowedDistance) { //Ok gui.pixelInset = tmprect; } else { //This is where I don't know what to do... } } if ( touch.phase == iPhoneTouchPhase.Ended || touch.phase == iPhoneTouchPhase.Canceled ) ResetJoystick(); } } } if ( !touchPad ) { // Get a value between -1 and 1 based on the joystick graphic location position.x = ( gui.pixelInset.x + guiTouchOffset.x - guiCenter.x ) / guiTouchOffset.x; position.y = ( gui.pixelInset.y + guiTouchOffset.y - guiCenter.y ) / guiTouchOffset.y; } // Adjust for dead zone float absoluteX = Mathf.Abs( position.x ); float absoluteY = Mathf.Abs( position.y ); if ( absoluteX < deadZone.x ) { // Report the joystick as being at the center if it is within the dead zone position.x = 0; } else if ( normalize ) { // Rescale the output after taking the dead zone into account position.x = Mathf.Sign( position.x ) * ( absoluteX - deadZone.x ) / ( 1 - deadZone.x ); } if ( absoluteY < deadZone.y ) { // Report the joystick as being at the center if it is within the dead zone position.y = 0; } else if ( normalize ) { // Rescale the output after taking the dead zone into account position.y = Mathf.Sign( position.y ) * ( absoluteY - deadZone.y ) / ( 1 - deadZone.y ); } } } So the later portion of the code handles the updated position of the joystick thumb. This is where I'd like it to track the finger position in a direction it still is allowed to move (like if the finger is too far up and slightly to the +X I'd like to make sure the joystick is as close in X and Y as allowed within the radius) Thanks for reading!

• Supporting copy 'n paste in your Windows Phone app

  - by Daniel Moth

  Some Windows Phone 7 owners already have the NoDo update, and others are getting it soon. This update brings, among other things, copy & paste support for text boxes. The user taps on a piece of text (and can drag in either direction to select more/less words), a popup icon appears that when tapped copies the text to the clipboard, and then at any app that shows the soft input panel there is an icon option to paste the copied text into the associated textbox. For more read this 'how to'. Note that there is no programmatic access to the clipboard, only the end user experience I just summarized, so there is nothing you need to do for your app's textboxes to support copy & paste: it just works. The only issue may be if in your app you use static TextBlock controls, for which the copy support will not appear, of course. That was the case with my Translator by Moth app where the translated text appears in a TextBlock. So, I wanted the user to be able to copy directly from the translated text (without offering an editable TextBox for an area where user input does not make sense). Take a look at a screenshot of my app before I made any changes to it. I then made changes to it preserving the look and feel, yet with additional copy support (see screenshot on the right)! So how did I achieve that? Simply by using my co-author's template (thanks Peter!): Copyable TextBlock for Windows Phone.   (aside: in my app even without this change there is a workaround, the user could use the "swap" feature to swap the source and target, so they can copy from the text box) Comments about this post welcome at the original blog.

• Game Center Leaderboard not dismissing

  - by FireStorm

  I was implementing Game Center into my app and all was going well except for the leaderboard done button not dismissing the leaderboard even with gameCenterControllerDidFinish added in. I call up the leaderboard with the touch of a button in the .m file as so: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInNode:self]; SKNode *node = [self nodeAtPoint:location]; if ([node.name isEqualToString:@"rankButton"]) { [self runAction:[SKAction playSoundFileNamed:@"fishtran.m4a" waitForCompletion: NO]]; GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init]; if (gameCenterController != nil) { gameCenterController.viewState = GKGameCenterViewControllerStateAchievements; UIViewController *vc = self.view.window.rootViewController; [vc presentViewController: gameCenterController animated: YES completion:nil]; } } else if ([node.name isEqualToString:@"Leaderboard"]) { GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init]; if (gameCenterController != nil) { gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards; UIViewController *vc = self.view.window.rootViewController; [vc presentViewController: gameCenterController animated: YES completion:nil]; } } ... and then I added thegameCenterControllerDidFinish immediately after as so: - (void)gameCenterControllerDidFinish:(GKGameCenterViewController*)gameCenterController { UIViewController *vc = self.view.window.rootViewController; [vc dismissViewControllerAnimated:YES completion:nil]; } and the done button still doesn't work and i haven't been able to find any solutions. And yes, I do have GKGameCenterControllerDelegate in my .h file. Any help would be greatly appreciated, Thanks!

• Windows 8 App Downloads Increasing + Over 5,000 Apps Available

  - by David Paquette

  Windows 8 will be unleashed on the general public tomorrow and I thought it would be a good time to review some of the numbers I have been tracking over the last month. Downloads of Windows 8 Apps have been steadily increasing over the last month.  Below is screenshot from the App Summary page for my Windows 8 app.  The blue line is my app, while the orange line is average for the top 5 apps in that subcategory.  Considering the large gap between the 2, I think it is safe to assume that my app is NOT in the top 5 in the subcategory. The spike in the last couple of days is fairly dramatic and I am a little surprised by that.  I would have expected that kind of spike on the days following the official release as opposed to the days leading up to the release.   Finally, the all important App count.  There have been some stories floating around that the Window 8 Store is a ghost town and that there are no apps available.  I think these might be exaggerating the situation a little.  As of this morning, in the US store there are over 5000 apps available for download.  Obviously a far cry from the hundreds of thousands available in other app stores, but we are seeing solid growth in this number. Less than a month ago, that number was 2000. That means the store more than doubled in less than a month. If the growth continues, it won’t be long before the Widows 8 Store is filled with all the apps you need (and a whole lot you don’t need).

• Windows 8 Store App Crash Logs

  - by David Paquette

  I was recently working on a Windows 8 app, and the application was crashing occasionally.  When resuming the application, the app would crash and close immediately without providing any feedback or information on what went wrong.  The crash was very difficult to reproduce, and I could never get the crash to occur when I was debugging through Visual Studio.  My app was crashing, and I had no idea what was going wrong!  HELP!!! After doing some digging, I found that when a Windows 8 Store App crashes, an error is logged in Windows Administrative Events.  You can view the details of any app crash by launching the Event Viewer and selecting Administrative Events under Custom Views.  The Source of the error will be listed as AppHost.  AppHost is the process that runs your Windows 8 Store App.  The error details contain all the information you would expect to find, including a stack trace and line numbers.   Windows 8 Tip:  A shortcut for launching the Event Viewer in Windows 8.  Right click on the bottom left corner of your desktop (where you normally click to go to the Start Screen).  A menu will appear with shortcuts to a number of common system tasks such as Event Viewer, Task Manager, Command Prompt, and Device Manager.

• Should Android and iPhone UI be different?

  - by Phonon

  I'm not completely new to developing apps, but I'm at a point where I'm trying to develop something and deploy it on several mobile platforms. To only concentrate on two major ones, suppose I'm developing an app for Android and iPhone and designing UI and the general user interaction architecture. Both platforms give guidelines as to how their UIs should work. For example, most iPhone apps have the Navigation Bar (the one that says Testing 1 and has a Back button) and an Icon Bar for navigating a program, while Android uses an Options Menu fetched via a Menu button and the "back" navigation is handled with the physical Back button on the device. I've seen many apps that try to force the same UI on every platform. For example, custom-building an iPhone style Icon Bar and putting it in their Android apps, but it just doesn't quite look right to me and it feels like it violates UI design guidelines somewhat. Are there any good design patters for implementing something sufficiently similar on both platforms, yet still platform-specific enough so that the user would not feel out of their comfort zone? What do people usually do in these situations?

• Google App Engine application instance recycling and response times...

  - by Konrad

  Hi, I posted this on GAE for Java group, but I hope to get some answers here quicker :) I decided to do some long-run performance tests on my application. I created some small client hitting app every 5-30 minutes and I run 3-5 of threads with such client. I noticed huge differenced in response times and started to investigate issue. I found reason very quick. I am experiencing same issues as described in following topics: Uneven response time between connection to server to first byte sent Application instances seem to be too aggressively recycled Getting 'Request was aborted after waiting too long to attempt to service your request.' after application idle I am using Springframework, it tkes around 18-20s to start app instance, which is causing response times to take from 1s (when requests hits running app - very rare) to 22s when fresh application is created. Is there any solution for this? I was thinking about creating most basic servlet performing critical tasks (serving API call) and leave UI as is. But then I would loose all benefits of Springframework. Is there any solution for this? After solving (hacking) numerous constrains of App Engine which I hit while developing my app that is the one I think will make me move out of App Engine... that's simply to much to all the time think how to win with GAE problems than how to solve my application problems... Any help? Regards Konrad

• How to combine twill and python into one code that could be run on "Google App Engine"?

  - by brilliant

  Hello everybody!!! I have installed twill on my computer (having previously installed Python 2.5) and have been using it recently. Python is installed on disk C on my computer: C:\Python25 And the twill folder (“twill-0.9”) is located here: E:\tmp\twill-0.9 Here is a code that I’ve been using in twill: go “some website’s sign-in page URL” formvalue 2 userid “my login” formvalue 2 pass “my password” submit go “URL of some other page from that website” save_html result.txt This code helps me to log in to one website, in which I have an account, record the HTML code of some other page of that website (that I can access only after logging in), and store it in a file named “result.txt” (of course, before using this code I firstly need to replace “my login” with my real login, “my password” with my real password, “some website’s sign-in page URL” and “URL of some other page from that website” with real URLs of that website, and number 2 with the number of the form on that website that is used as a sign-in form on that website’s log-in page) This code I store in “test.twill” file that is located in my “twill-0.9” folder: E:\tmp\twill-0.9\test.twill I run this file from my command prompt: python twill-sh test.twill Now, I also have installed “Google App Engine SDK” from “Google App Engine” and have also been using it for awhile. For example, I’ve been using this code: import hashlib m = hashlib.md5() m.update("Nobody inspects") m.update(" the spammish repetition ") print m.hexdigest() This code helps me transform the phrase “Nobody inspects the spammish repetition” into md5 digest. Now, how can I put these two pieces of code together into one python script that I could run on “Google App Engine”? Let’s say, I want my code to log in to a website from “Google App Engine”, go to another page on that website, record its HTML code (that’s what my twill code does) and than transform this HTML code into its md5 digest (that’s what my second code does). So, how can I combine those two codes into one python code? I guess, it should be done somehow by importing twill, but how can it be done? Can a python code - the one that is being run by “Google App Engine” - import twill from somewhere on the internet? Or, perhaps, twill is already installed on “Google App Engine”?

• How to setup a static multicast ARP entry with Cisco SG300?

  - by Fredrik Hedberg

  We're running a Microsoft NLB cluster in multicast mode as a loadbalancer. Using our old Cisco IOS switches we propagate access to the cluster to our branches using a static ARP entry in the core router: arp 10.20.1.226 03bf.0a14.01e2 ARPA But how does one solve this using non-IOS based Cisco hardware such as the SG300 series? Adding a static ARP entry results in an error message telling the user that the hardware address needs to be a valid unicast MAC address.

• Can I see the SMTP session log when Mail.app connects to an SMPT server?

  - by Charles Stewart

  Problem: I've set up a mail server using SASL authentication, and have given Mail.app (on Mac Os 10.4) the login information it needs to connect. I wrote a test message for it to deliver to my server: the Activity window shows that it tries to deliver the message, but then it simply stops, with no indication of error, except that the test message is left in the Outbox. How can I find out what went wrong? Is there some log file I don't know about?

  I've been using Coda recently. It's a great program, but overkill for just a multi session Mac terminal app. Know of a better alternative, especially with a command snippet library function?

• In Mail.app, move the reply to the original email's folder?

  - by Charles Brossollet

  As many, I find it handy to have emails organized by folders, but I don't like the fact that sent mails are in a separate folder. My idea would be that when I answer to an email that is already in a folder, the answer is placed automatically in that same folder. Is there a script or a plugin to do this in Mail.app? The corresponding add-on for thunderbird is Copy sent to current
