• bash bcmath functions

  - by Gordon

  I have two functions for GNU bc in a Bash script. BC_CEIL="define ceil(x) { if (x>0) { if (x%1>0) return x+(1-(x%1)) else return x } else return -1*floor(-1*x) }\n" BC_FLOOR="define floor(x) { if (x>0) return x-(x%1) else return -1*ceil(-1*x) }\n" echo -e "scale=2"$BC_CEIL$BC_FLOOR"ceil(2.5)" | bc Both functions work fine in interactive bc. bc does not seem to allow multiple functions on one line separated by ; though, so I have to echo -n | bc with newlines at the end of each function. The above output is 2.5, not the expected 3.0 that I get if I type it into bc -i myself. It seems that bash calls bc for each line of echo output, rather than echo'ing it all to a single instance. Is there any workaround for this?

• Dealing with UIImagePickerController to minimize memory useage

  - by Gordon Fontenot

  So, I have read the SO post on UIImagePickerController, UIImage, Memory and More, and I read the post on Memory Leak Problems with UIImagePickerController in iPhone. I have VASTLY increased my memory efficiency between these 2 posts, and I thank the OPs and the people that provided the answers. I just had a question on the answer provided in the Memory Leak question, which was (essentially): only have one instance of the controller throughout the programs runtime What would be the best way to go about this without causing memory leaks? Right now I am initiating it and releasing it on every use from within the view, and I am seeing exactly what the answer describes (Memory warnings and a crash after about 20 uses). Should I initiate the UIImagePickerController when I need it, but use a seperate class unrelated to the view to control it? How should I deal with releasing the controller if I do it this way?

• extjs how to make a nested child using xTemplate when we don't know how deep is it?

  - by Ebo the gordon

  first, sorry if my english bad,.... in my script, variable tplData below is dynamic,... (lets say it generates from database) so, every chid, can have another child. and so on,.... now, i'm stack how to iteration it,.. var tplData = [{ name : 'Naomi White' },{ name : 'Yoko Ono' },{ name : 'John Smith', child : [{ name:'Michael (John\'s son)', child: [{ name : 'Brad (Michael\'s son,John\'s grand son)' },{ name : 'Brid (Michael\'s son,John\'s grand son)', child: [{ name:'Buddy (Brid\'s son,Michael\'s grand son)' }] },{ name : 'Brud (Michael\'s son,John\'s grand son)' }] }] }]; var myTpl = new Ext.XTemplate( '<tpl for=".">', '<div style="background-color: {color}; margin: 10px;">', '<b> Name :</b> {name}<br />', // how to make this over and over every child (while it has ) '<tpl if="typeof child !=\'undefined\'">', '<b> Child : </b>', '<tpl for="child">', '{name} <br />', '</tpl>', '</tpl>', /////////////////////////////////////// '</div>', '</tpl>' ); myTpl.compile(); myTpl.overwrite(document.body, tplData);

• Copy an entity in Google App Engine datastore in Python without knowing property names at 'compile'

  - by Gordon Worley

  In a Python Google App Engine app I'm writing, I have an entity stored in the datastore that I need to retrieve, make an exact copy of it (with the exception of the key), and then put this entity back in. How should I do this? In particular, are there any caveats or tricks I need to be aware of when doing this so that I get a copy of the sort I expect and not something else. ETA: Well, I tried it out and I did run into problems. I would like to make my copy in such a way that I don't have to know the names of the properties when I write the code. My thinking was to do this: #theThing = a particular entity we pull from the datastore with model Thing copyThing = Thing(user = user) for thingProperty in theThing.properties(): copyThing.__setattr__(thingProperty[0], thingProperty[1]) This executes without any errors... until I try to pull copyThing from the datastore, at which point I discover that all of the properties are set to None (with the exception of the user and key, obviously). So clearly this code is doing something, since it's replacing the defaults with None (all of the properties have a default value set), but not at all what I want. Suggestions?

• Managing several hundred occurrences of NSLocalizedString

  - by Gordon Hughes

  My application has several hundred points of localisation, some of which can be reused many times. To prevent from hunting and pecking through code to find occurrences of a particular NSLocalizedString, I create a macro for each in a header file using the #define preprocessor directive. For example: #define kLocFirstString NSLocalizedString(@"Default Text", @"Comment") #define kLocSecondString NSLocalizedString(@"More Text", @"Another comment") ... When I want to refer to a particular string, I do so by its macro name. This method has been working nicely for me, but I'm concerned that such blatant abuse of #define is frowned upon. From the standpoint of "correctness", should I just inline each NSLocalizedString with the code, or is there another method (extern NSString *aString; perhaps?) that I can use to collect the declarations in one place?

• Properly declare delegation in Objective C (iPhone)

  - by Gordon Fontenot

  Ok, This has been explained a few times (I got most of the way there using this post on SO), but I am missing something. I am able to compile cleanly, and able to set the delegate as well as call methods from the delegate, but I'm getting a warning on build: No definition of protocol 'DetailViewControllerDelegate' is found I have a DetailViewController and a RootViewController only. I am calling a method in RootViewController from DetailViewController. I have the delegate set up as so: In RootViewController.h: #import "DetailViewController.h" @interface RootViewController : UITableViewController <NSFetchedResultsControllerDelegate, DetailViewControllerDelegate> //Error shows up here { //Some Stuff Here } //Some other stuff here @end In RootViewController.m I define the delegate when I create the view using detailViewController.delegate = self In DetailViewController.h: @protocol DetailViewControllerDelegate; #import "RootViewController.h" @interface DetailViewController : UITableViewController <UITextFieldDelegate> { id <DetailViewControllerDelegate> delegate; } @property (nonatomic, assign) id <DetailViewControllerDelegate> delegate; @end @protocol DetailViewControllerDelegate //some methods that reside in RootViewController.m @end I feel weird about declaring the protocol above the import in DetailViewController.h, but if I don't it doesn't build. Like I said, the methods are called fine, and there are no other errors going on. What am I missing here?

• Straw Poll - K&R vs BSD

  - by Gordon Mackie JoanMiro

  No holy wars please - (ultimately a standardised and consistently-observed house-style on a project always wins out whatever is chosen), but I am genuinely interested in the preferences of people for K&R style formatting: public bool CompareObjects(object first, object second) { if (first == second) { return true; } else { return false; } } over BSD style: public bool CompareObjects(object first, object second) { if (first == second) { return true; } else { return false; } } K&R seems to be making a bit of a comeback recently (I'm an old programmer, so I've seen these things fluctuate); do people think K&R looks more professional, more cool, more readable, is compactness when viewing more important than extending the structure down the screen? Please use the 2 community wiki answers below to vote for K&R vs. BSD. Polls shouldn't earn rep for the first person that manages to type "BSD FTW!" My God! This question is nearly 2 years old and people are still down-voting it; ENOUGH!

• Passing row from UIPickerView to integer CoreData attribute

  - by Gordon Fontenot

  I'm missing something here, and feeling like an idiot about it. I'm using a UIPickerView in my app, and I need to assign the row number to a 32-bit integer attribute for a Core Data object. To do this, I am using this method: -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { object.integerValue = row; } This is giving me a warning: warning: passing argument 1 of 'setIntegerValue:' makes pointer from integer without a cast What am I mixing up here? --EDIT 1-- Ok, so I can get rid of the errors by changing the method to do the following: NSNumber *number = [NSNumber numberWithInteger:row]; object.integerValue = rating; However, I still get a value of 0 for object.integerValue if I use NSLog to print it out. object.integerValue has a max value of 5, so I print out number instead, and then I'm getting a number above 62,000,000. Which doesn't seem right to me, since there are 5 rows. If I NSLog the row variable, I get a number between 0 and 5. So why do I end up with a completely different number after casting the number to NSNumber?

• Auto-generating toString Method

  - by Gordon

  Is it good or bad practice auto-generating toString methods for some simple classes? I was thinking of generating something like bellow where it takes the variable names and produces a toString method that prints the name followed by it's value. private String name; private int age; private double height; public String toString(){ Formatter formatter = new Formatter(); return formatter.format("Name: %s, Age: %d, Height %f", name, age, height).toString(); }

• How do I reset a form in an ajax callback?

  - by B.Gordon

  I am sending a form using simple ajax and returning the results in a div above the form. The problem is that after the form is submitted and validated, I display a thank you and want to reset the form so they don't just press the submit button again... Can't seem to find the right code to do this... <form id="myForm" target="sendemail.php" method="post"> <div id="results"></div> <input type="text" name="value1"> <input type="text" name="value2"> <input type="submit" name="submit"> </form> So, my sendemail.php validation errors and success messages appear in #results without problems. But... when I try to send back a javascript form reset command, it does not work. Naturally I cannot see it in the source code since it is an AJAX callback so I don't know if that is the issue or if I am just using the wrong syntax. echo "<p>Thank you. Your message has been accepted for delivery.</p>"; echo "<script type=\"text/javascript\">setTimeout('document.getElementById('myForm').reset();',1000);</script>"; Any ideas gurus?

• Using trace and dbg in Erlang

  - by Gordon Guthrie

  I am trying to start using erlang:trace/3 and the dbg module to trace the behaviour of a live production system without taking the server down. The documentation is opaque (to put it mildly) and there don't appear to be any useful tutorials online. What I spent all day trying to do was capture what was happening in a particular function by trying to apply a trace to module:function using dbg:c and dbg:p but with no success at all... Does anyone have a succinct explanation of how to use trace in a live Erlang system?

• Java OutOfMemoryError message changes when trying to create Arrays of different sizes

  - by Gordon

  In the question by DKSRathore How to simulate the Out Of memory : Requested array size exceeds VM limit some odd behavior was noted when creating an arrays. When creating an array of size Integer.MAX_VALUE an exception with the error java.lang.OutOfMemoryError Requested array size exceeds VM limit was thrown. However when an array was created with a size less than the max but still above the virtual machine memory limit the error message read java.lang.OutOfMemoryError: Java heap space. Testing further I managed to narrow down where the error messages changes. long[] l = new long[2147483645]; exceptions message reads - Requested array size exceeds VM limit long[] l = new long[2147483644]; exceptions message reads - Java heap space errors I increased my virtual machine memory and still produced the same result. Has anyone any idea why this happens? Some extra info: Integer.MAX_VALUE = 2147483647. Edit: Here's the code I used to find the value, might be helpful. int max = Integer.MAX_VALUE; boolean done = false; while (!done) { try { max--; // Throws an error long[] l = new long[max]; // Exit if an error is no longer thrown done = true; } catch (OutOfMemoryError e) { if (!e.getMessage().contains("Requested array size exceeds VM limit")) { System.out.println("Message changes at " + max); done = true; } } }

• Code Access Security and Sharepoint WebParts

  - by Gordon Carpenter-Thompson

  I've got a vague handle on how Code Access Security works in Sharepoint. I have developed a custom webpart and setup a CAS policy in my Manifest <CodeAccessSecurity> <PolicyItem> <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for Okana"> <IPermission class="Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" version="1" ObjectModel="True" Impersonate="True" /> <IPermission class="SecurityPermission" version="1" Flags="Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration" /> <IPermission class="AspNetHostingPermission" version="1" Level="Medium" /> <IPermission class="DnsPermission" version="1" Unrestricted="true" /> <IPermission class="EventLogPermission" version="1" Unrestricted="true"> <Machine name="localhost" access="Administer" /> </IPermission> <IPermission class="EnvironmentPermission" version="1" Unrestricted="true" /> <IPermission class="System.Configuration.ConfigurationPermission, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" version="1" Unrestricted="true"/> <IPermission class="System.Net.WebPermission, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Unrestricted="true" /> <IPermission class="System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" PathDiscovery="*AllFiles*" /> <IPermission class="IsolatedStorageFilePermission" version="1" Allowed="AssemblyIsolationByUser" UserQuota="9223372036854775807" /> <IPermission class="PrintingPermission" version="1" Level="DefaultPrinting" /> <IPermission class="PerformanceCounterPermission" version="1"> <Machine name="localhost"> <Category name="Enterprise Library Caching Counters" access="Write"/> <Category name="Enterprise Library Cryptography Counters" access="Write"/> <Category name="Enterprise Library Data Counters" access="Write"/> <Category name="Enterprise Library Exception Handling Counters" access="Write"/> <Category name="Enterprise Library Logging Counters" access="Write"/> <Category name="Enterprise Library Security Counters" access="Write"/> </Machine> </IPermission> <IPermission class="ReflectionPermission" version="1" Unrestricted="true"/> <IPermission class="SecurityPermission" version="1" Flags="SerializationFormatter, UnmanagedCode, Infrastructure, Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration, ControlAppDomain,ControlDomainPolicy" /> <IPermission class="SharePointPermission" version="1" ObjectModel="True" /> <IPermission class="SmtpPermission" version="1" Access="Connect" /> <IPermission class="SqlClientPermission" version="1" Unrestricted="true"/> <IPermission class="WebPartPermission" version="1" Connections="True" /> <IPermission class="WebPermission" version="1"> <ConnectAccess> <URI uri="$OriginHost$"/> </ConnectAccess> </IPermission> </PermissionSet> <Assemblies> .... </Assemblies> This is correctly converted into a wss_custom_wss_minimaltrust.config when it is deployed onto the Sharepoint server and mostly works. To get the WebPart working fully, however I find that I need to modify the wss_custom_wss_minimaltrust.config by hand after deployment and set Unrestricted="true" on the permissions set <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1"> to <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1" Unrestricted="true"> It's all because I'm loading a User Control from the webpart. I don't believe there is a way to enable that using CAS but am willing to be proven wrong. Is there a way to set something in the manifest so I don't need to make this fix by hand? Thanks

• Correct way of setting a custom FileInfo class to an Iterator

  - by Gordon

  I am trying to set a custom class to an Iterator through the setInfoClass method: Use this method to set a custom class which will be used when getFileInfo and getPathInfo are called. The class name passed to this method must be derived from SplFileInfo. My class is like this (simplified example): class MyFileInfo extends SplFileInfo { public $props = array( 'foo' => '1', 'bar' => '2' ); } The iterator code is this: $rit = new RecursiveIteratorIterator( new RecursiveDirectoryIterator('/some/file/path/'), RecursiveIteratorIterator::SELF_FIRST); Since RecursiveDirectoryIterator is by inheritance through DirectoryIterator also an SplFileInfo object, it provides the setInfoClass method (it's not listed in the manual, but reflection shows it's there). Thus I can do: $rit->getInnerIterator()->setInfoClass('MyFileInfo'); All good up to here, but when iterating over the directory with foreach($rit as $file) { var_dump( $file ); } I get the following weird result object(MyFileInfo)#4 (3) { ["props"]=>UNKNOWN:0 ["pathName":"SplFileInfo":private]=>string(49) "/some/file/path/someFile.txt" ["fileName":"SplFileInfo":private]=>string(25) "someFile.txt" } So while MyFileInfo is picked up, I cannot access it's properties. If I add custom methods, I can invoke them fine, but any properties are UNKNOWN. If I don't set the info class to the iterator, but to the SplFileInfo object (like shown in the example in the manual), it will give the same UNKNOWN result: foreach($rit as $file) { // $file is a SplFileInfo instance $file->setInfoClass('MyFileInfo'); var_dump( $file->getFileInfo() ); } However, it will work when I do foreach($rit as $file) { $file = new MyFileInfo($file); var_dump( $file ); } Unfortunately, the code I a want to use this in is somewhat more complicated and stacks some more iterators. Creating the MyFileInfo class like this is not an option. So, does anyone know how to get this working or why PHP behaves this weird? Thanks.

• UML Modelling in C++Builder 2010 Professional

  - by Gordon Brandly

  I'd like to do some basic class diagram UML models in the Pro version of C++Builder 2010. Embarcadero has a C++Builder Features Matrix document, one line of which says "UML Code Visualization – at any time, get a UML model view of your source code" and has a check in the "Professional" column of that table -- I assume this means it should be available to me. Yet, when I open an existing project and do a View | Model View, there's nothing in the Model View window. The only diagram I can find is on the Graph tab of the C++ Class Explorer. I wouldn't call that a UML diagram myself -- is that what Embarcadero is referring to? Embarcadero's table shows that many UML diagrams are not available in Pro, but it looks to me like Class Diagrams should be available. Other lines in that same table indicate that both "Full two-way class diagrams with synchronization between code and diagrams" and "Diagram hyper-linking and annotations" are also supposed to be available in Pro. The Class Explorer graph is one-way only as far as I can tell, so I hope they're referring to something else I haven't been able to find so far. Thanks for any insight into this.

• Fetching Core Data for Tableview on iPhone - Tutorial leaves me with crashes when adding items to a

  - by Gordon Fontenot

  Been following the Core Data tutorial on Apple's developer site, and all is good until I have to add something to the fetched store. I am getting this error after a successful build and load when I try to add a new item to the list: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (0) must be equal to the number of rows contained in that section before the update (0), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted). Due to the fact that the fetch goes through fine, and that if I replace the fetching with eventList = [[NSMutableArray alloc] init] it works as expected (without persistance, of course), I am led to believe that the problem comes from not creating the Mutable Array correctly. Here's the problematic part of the code: NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Event" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"creationDate" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptors release]; [sortDescriptor release]; NSError *error; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if (mutableFetchResults = nil) { //Handle the error } [self setEventList:mutableFetchResults]; [mutableFetchResults release]; [request release]; I have tried switching the NSArrays in the second chunk out with NSMutableArrays, but I still get the same error. For reference, the section of code that is throwing the error when I try adding an entry is here: [eventList insertObject:event atIndex:0]; NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES]; it errors out at the insertRowsAtIndexPaths call. Thanks in advance for any help

• How does a programmer think?

  - by Gordon Potter

  This may be a hopelessly vague question. But I am interested to hear whatever logical thought processes people go through when learning a new concept or trying to get their brain around code they might not have ever seen before. Basically, what general steps does one take to to break down problems and what does it take to "get it"? If you were to diagram a flowchart of how your mental process works when you look at code or try to solve a problem what might it look like? What common references, tips, and mental assumptions do you find useful in problem solving? How is this different between different domains? For example in what ways is a web programmer's thought process similar or different from a traditional desktop app developer's process?

  I had the idea that I would write my GroovyDao as a grails service. Next I would write a MyJavaService in java and locate it in the java sources dir in my grails app. MyJavaService contains a instance reference to groovyDao for spring injection. I would wire up in resources.groovy the MyJavaService with a groovyDao = ref("GroovyDao"). Everything starts up fine. However if I make call to MyJavaService any Domain method like Domain.list() returns a Method not found error. Any help is appreciated.

• CSS3PIE issues in IE6 and 8

  - by Gordon

  I'm using CSS3PIE to apply some rounded corners to elements in Internet Explorer that will get them by stylesheet in other browsers. I've run into some issues with it though. In IE8, I discovered that any element that had the PIE behaviour would behave strangely. The container would jump a few pixels to the right, but the content would stay in its original position, giving the appearance that the content had all shifted left relative to its container. This would be especially problematic on elements with no or small amounts of padding. I was able to hack my way around the problem in IE8 by using X-UA-Compatible, but I'd rather avoid this solution if at all possible. I don't have access to IE9 for testing but my understanding hacks like PIE aren't necessary and it would be wasteful to force a compatibility mode in a browser that doesn't need it. I have worse issues in IE6, with the PIE layout breaking down completely on a list that is set up to use display:inline; zoom:1; list items (to simulate inline-block, which works in IE8 and the other browsers). Here the borders of the list items get rendered in completely the wrong place. So ideally, I'd like to have PIE work properly in IE6, and in IE8 without having to resort to compatibility mode. As far as IE6 goes, a graceful fallback where PIE is just not applied will do. IE7 is the only browser where the page displays as intended. I can't provide an example page just at the moment unfortunately, I can add one later though. Follow up: Here are some screen grabs made with IE Tester. I'm hoping they will make things a little more clear for everybody. As you can see, IE7 is fine. However, in IE8, the containers are offset to the left relative to their content, and in IE6 the list elements (with the rounded 1 pixel border) are a complete mess! Full size versions for IE8, IE7 and IE6 are also available
