Will Apple bundle the Mono Touch runtime with every iPhone?

- by Zoran Simic

It strikes me as a good idea for Apple to negotiate with Novell and bundle the Mono Touch runtime (only the runtime of course) into every iPhone and iPod Touch. Perhaps even make it a "one time install" that automatically gets downloaded from the App Store the first time one downloads an app build with Mono Touch, making every subsequent Mono Touch app much lighter to download (without the runtime). Doing so would be similar in a way to adding Bootcamp to OS X: it would make it easier for C# developers to join the party, but that wouldn't mean these developers will all stick to C#... What convinced me to buy a Mac is Bootcamp - I figured I could always install Windows if I didn't like OS X (and I liked the hardware, so no problem there). 6 months later, I'm using OS X full time... Would there be any technical issues in doing so? I see only advantages for all parties, not one disadvantage to anyone (except maybe for the few unfortunate Apple employees who would have to test the crap out of the Mono Touch runtime before bundling it): Novell wins because Mono Touch becomes much more viable (Mono Touch apps become much lighter all of the sudden) Developers win because now there's one more tool in the tool belt Many C# Developers would be very interested by this Apple wins because that would bring even more attention to the platform, more revenue in developer fees, more potential great apps, etc Users win because less space is used by different Apps having copies of the same runtime accumulating on their devices Would there be a major technical obstacle in bundling Mono Touch to iPhone OS? Edit: Changed the title from "Should" to "Will Apple bundle the runtime?", I think the consensus on predicting that means a lot to those considering going with Mono Touch.

Prototypal inheritance should save memory, right?

- by Techpriester

Hi Folks, I've been wondering: Using prototypes in JavaScript should be more memory efficient than attaching every member of an object directly to it for the following reasons: The prototype is just one single object. The instances hold only references to their prototype. Versus: Every instance holds a copy of all the members and methods that are defined by the constructor. I started a little experiment with this: var TestObjectFat = function() { this.number = 42; this.text = randomString(1000); } var TestObjectThin = function() { this.number = 42; } TestObjectThin.prototype.text = randomString(1000); randomString(x) just produces a, well, random String of length x. I then instantiated the objects in large quantities like this: var arr = new Array(); for (var i = 0; i < 1000; i++) { arr.push(new TestObjectFat()); // or new TestObjectThin() } ... and checked the memory usage of the browser process (Google Chrome). I know, that's not very exact... However, in both cases the memory usage went up significantly as expected (about 30MB for TestObjectFat), but the prototype variant used not much less memory (about 26MB for TestObjectThin). I also checked: The TestObjectThin instances contain the same string in their "text" property, so they are really using the property of the prototype. Now, I'm not so sure what to think about this. The prototyping doesn't seem to be the big memory saver at all. I know that prototyping is a great idea for many other reasons, but I'm specifically concerned with memory usage here. Any explanations why the prototype variant uses almost the same amount of memory? Am I missing something?

Losing URI segments when paginating with CodeIgniter

- by Danny Herran

I have a /payments interface where the user should be able to filter via price range, bank, and other stuff. Those filters are standard select boxes. When I submit the filter form, all the post data goes to another method called payments/search. That method performs the validation, saves the post values into a session flashdata and redirects the user back to /payments passing the flashdata name via URL. So my standard pagination links with no filters are exactly like this: payments/index/20/ payments/index/40/ payments/index/60/ And if you submit the filter form, the returning URL is: payments/index/0/b48c7cbd5489129a337b0a24f830fd93 This works just great. If I change the zero for something else, it paginates just fine. The only issue however is that the << 1 2 3 4 page links wont keep the hash after the pagination offset. CodeIgniter is generating the page links ignoring that additional uri segment. My uri_segment config is already set to 3: $config['uri_segment'] = 3; I cannot set the page offset to 4 because that hash may or may not exists. Any ideas of how can I solve this? Is it mandatory for CI to have the offset as the last segment in the uri? Maybe I am trying an incorrect approach, so I am all ears. Thank you folks.

Problem implementing Interceptor pattern

- by ph0enix

I'm attempting to develop an Interceptor framework (in C#) where I can simply implement some interfaces, and through the use of some static initialization, register all my Interceptors with a common Dispatcher to be invoked at a later time. The problem lies in the fact that my Interceptor implementations are never actually referenced by my application so the static constructors never get called, and as a result, the Interceptors are never registered. If possible, I would like to keep all references to my Interceptor libraries out of my application, as this is my way of (hopefully) enforcing loose coupling across different modules. Hopefully this makes some sense. Let me know if there's anything I can clarify... Does anyone have any ideas, or perhaps a better way to go about implementing my Interceptor pattern? Update: I came across Spring.NET. I've heard of it before, but never really looked into it. It sounds like it has a lot of great features that would be very useful for what I'm trying to do. Does anyone have any experience with Spring.NET? TIA, Jeremy

CLI include paths to run zend framework via cron

- by summerg

I wrote a command line utility using Zend Framework to do some nightly reporting. It uses a ton of the same functionality the accompanying site. It works great when I run it by hand, but when I run it on cron I have include path issues. Seems like it should be easily fixed with set_include_path, but maybe I'm missing something? My directory structure looks like this: /var/www/clientname/ application Globals.php commandline commandline_bootstrap.php public_html public_bootstrap.php library Zend In public_bootstrap.php I use set_include_path without a problem, relative to the current directory: set_include_path('../library' . PATH_SEPARATOR . get_include_path()); If I understand correctly, in commandline_bootstrap.php I need to put in the absolute path, so cron knows where everything is. My file starts like this: error_reporting(E_ALL); set_include_path('/var/www/clientname/library' . PATH_SEPARATOR . get_include_path()); require_once "../application/Globals.php"; But when I run it via cron I get the following error: PHP Fatal error: require_once(): Failed opening required '../application/Globals.php' (include_path='/var/www/clientname/library/') in /var/www/clientname/commandline/zfcli.php on line 11 I think PHP is accepting my new path, because when I run it command line and dump the phpinfo I can see: include_path = /var/www/clientname/library/:.:/usr/share/pear:/usr/share/php = .:/usr/share/pear:/usr/share/php I admit the syntax here looks a little strange, but I can’t figure out how to fix it. Any suggestions would be greatly appreciated. Thanks summer

Giving another object a NSManagedObject

- by Wayfarer

Alright, so I'm running into an issue with my code. What I have done is subclassed UIButton so I can give it some more infomormation that pertain to my code. I have been able to create the buttons and they work great. Capiche. However, one of the things I want my subclass to hold is a reference to a NSMangedObject. I have this code in my header file: @interface ButtonSubclass : UIButton { NSManagedObjectContext *context; NSManagedObject *player; } @property (nonatomic, retain) NSManagedObject *player; @property (nonatomic, retain) NSManagedObjectContext *context; - (id)initWithFrame:(CGRect)frame andTitle:(NSString*)title; //- (void)setPlayer:(NSManagedObject *)aPlayer; @end As you can see, it has a instance variable to the NSMangedobject I want it to hold (as well as the Context). But for the life of me, I can't get it to hold that NSManagedObject. I run both the @synthesize methods in the Implementation file. @synthesize context; @synthesize player; So I'm not sure what I'm doing wrong. This is how I create my button: ButtonSubclass *playerButton = [[ButtonSubclass alloc] initWithFrame:frame andTitle:@"20"]; //works playerButton.context = self.context; //works playerButton.player = [players objectAtIndex:i]; //FAILS And I have initilaized the players array earlier, where I get the objects. Another weird thing is that when it gets to this spot in the code, the app crashes (woot) and the the console output stops. It doesn't give me any error, and notification at all that the app has crashed. It just... stops. So I don't even know what the error is that is crashing the code, besides it has to do with that line up there setting the "player" variable. Thoughts and ideas? I'd love your wisdom!

Ideas Related to Subset Sum with 2,3 and more integers

- by rolandbishop

I've been struggling with this problem just like everyone else and I'm quite sure there has been more than enough posts to explain this problem. However in terms of understanding it fully, I wanted to share my thoughts and get more efficient solutions from all the great people in here related to Subset Sum problem. I've searched it over the Internet and there is actually a lot sources but I'm really willing to re-implement an algorithm or finding my own in order to understand fully. The key thing I'm struggling with is the efficiency considering the set size will be large. (I do not have a limit, just conceptually large). The two phases I'm trying to implement ideas on is finding two numbers that are equal to given integer T, finding three numbers and eventually K numbers. Some ideas I've though; For the two integer part I'm thing basically sorting the array O(nlogn) and for each element in the array searching for its negative value. (i.e if the array element is 3 searching for -3). Maybe a hash table inclusion could be better, providing a O(1) indexing the element? For the three or more integers I've found an amazing blog post;http://www.skorks.com/2011/02/algorithms-a-dropbox-challenge-and-dynamic-programming/. However even the author itself states that it is not applicable for large numbers. So I was for 2 and 3 and more integers what ideas could be applied for the subset problem. I'm struggling with setting up a dynamic programming method that will be efficient for the large inputs as well.

Removing HTML entities while preserving line breaks with JSoup

- by shrodes

I have been using JSoup to parse lyrics and it has been great until now, but have run into a problem. I can use Node.html() to return the full HTML of the desired node, which retains line breaks as such: Glóandi augu, silfurnátt <br />Blóð alvöru, starir á <br />Óður hundur er í vígamóð, í maga... mér <br /> <br />Kolniður gref, kvik sem dreg hér <br />Kolniður svart, hvergi bjart né But has the unfortunate side-effect, as you can see, of retaining HTML entities and tags. However, if I use Node.text(), I can get a better looking result, free of tags and entities: Glóandi augu, silfurnátt Blóð alvöru, starir á Óður hundur er í vígamóð, í maga... mér Kolniður gref, kvik sem dreg hér Kolniður svart, Which has another unfortunate side-effect of removing the line breaks and compressing into a single line. Simply replacing <br /> from the node before calling Node.text() yields the same result, and it seems that that method is compressing the text onto a single line in the method itself, ignoring newlines. Is it possible to have the best of both worlds, and have tags and entities replaced correctly which preserving the line breaks, or is there another method or way of decoding entities and removing tags without having to replace them manually?

How to get more detail from an exception?

- by cusimar9

I have a .NET 4.0 web application which implements an error handler within the Application_Error event of Global.asax. When an exception occurs this intercepts it and sends me an email including a variety of information like the logged in user, the page the error occurred on, the contents of the session etc. This is all great but there is some fundamental detail missing which I seem unable to locate. For instance, this is a subset of an error I would receive and the associated stack trace: Source: Telerik.Web.UI Message: Selection out of range Parameter name: value Stack trace: at Telerik.Web.UI.RadComboBox.PerformDataBinding(IEnumerable dataSource) at Telerik.Web.UI.RadComboBox.OnDataSourceViewSelectCallback(IEnumerable data) at System.Web.UI.DataSourceView.Select(DataSourceSelectArguments arguments, DataSourceViewSelectCallback callback) at Telerik.Web.UI.RadComboBox.OnDataBinding(EventArgs e) at Telerik.Web.UI.RadComboBox.PerformSelect() at System.Web.UI.WebControls.BaseDataBoundControl.DataBind() at Telerik.Web.UI.RadComboBox.DataBind() at System.Web.UI.WebControls.BaseDataBoundControl.EnsureDataBound() at Telerik.Web.UI.RadComboBox.OnPreRender(EventArgs e) at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) Now as lovely as this is I could do with knowing a) the name of the control and b) the value which caused the control to be 'out of range'. Any suggestions about how I could get this sort of information? I've run this in debug mode and the objects passed to Global.asax don't seem to hold any more detail that I can see.

Reverse alphabetic sort multidimensional PHP array maintain key

- by useyourillusiontoo

I'm dying here, any help would be great. I've got an array that I can sort a-z on the value of a specific key but cannot sort in reverse z-a. sample of my array which i'd like to sort by ProjectName (z-a): Array ( [0] => Array ( [count] => 1 [ProjectName] => bbcjob [Postcode] => 53.471922,-2.2996078 [Sector] => Public ) [1] => Array ( [count] => 1 [ProjectName] => commercial enterprise zone [Postcode] => 53.3742081,-1.4926439 [Sector] => Public ) [2] => Array ( [count] => 1 [ProjectName] => Monkeys eat chips [Postcode] => 51.5141492,-0.2271227 [Sector] => Private the desired results would be to maintain the entire array key - value structure but with the order: Monkeys eat chips Commericial enterprise zone bbcjob I hope this makes sense

MapScale not being persisted properly in mxd when programmatically changed outside of ArcMap environ

- by Vidar

I am trying to change the scale of a map in an mxd OUTSIDE of ArcMap in a standalone Windows application. The problem is the scale is never persisted - the best code I have come up with is the following: private void UpdateMapScaleInMxd(double scale, string mxdFullPath) { IMapDocument mapDocument = new MapDocumentClass(); mapDocument.Open(mxdFullPath, ""); IPageLayout pageLayout = (IPageLayout)mapDocument.ActiveView; IGraphicsContainer graphicsContainer = (IGraphicsContainer)pageLayout; graphicsContainer.Reset(); IMapFrame mapFrame; IActiveView tmpActiveView = null; IElement element = graphicsContainer.Next(); while (element != null) { if (element is IMapFrame) { mapFrame = (IMapFrame)element; tmpActiveView = (IActiveView)mapFrame.Map; mapFrame.ExtentType = esriExtentTypeEnum.esriExtentScale; mapFrame.MapScale = scale; tmpActiveView.Refresh(); } element = graphicsContainer.Next(); } mapDocument.Save(false, false); mapDocument.Close(); } I check the mxd by opening it up in ArcMap and the map scale has changed, although the little combobox to change the scale is now greyed out - does anyone know what that means!? So now I try to export the map as a PDF in code - and the most frustrating thing is - it exports the map at the previous scale that was set - NOT the scale I just changed it to! So infuriating - if anyone can help me understand where I am going wrong that would be great.

Javascript AJAX function not working properly

- by Or W

I have a function that sends a GET request to a php script and checks if the script returned any output. It works great, but when I try to add another function that checks for something similar, both of them fail. What am I missing? function checkUsername(usr,n) { var user = usr.val(), xmlhttp; //var str = document.getElementById('email').value; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { //document.getElementById("txtHint").innerHTML=xmlhttp.responseText; if (xmlhttp.responseText != "") { usr.addClass( "ui-state-error" ); updateTips( n ); return false; } else { return true; } } } xmlhttp.open("GET","ajaxValidate.php?type=user&q="+user,true); xmlhttp.send(); } The above works perfectly, when adding this function, none of them work: function checkEmail(em,n) { var email = em.val(), xmlhttp; //var str = document.getElementById('email').value; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { //document.getElementById("txtHint").innerHTML=xmlhttp.responseText; if (xmlhttp.responseText != "") { em.addClass( "ui-state-error" ); updateTips( n ); return false; } else { return true; } } } xmlhttp.open("GET","ajaxValidate.php?type=email&q="+email,true); xmlhttp.send(); }

What arguments to use to explain why SQL Server is far better then a flat file

- by jamone

The higher ups in my company were told by good friends that flat files are the way to go, and we should switch from SQL Server to them for everything we do. We have over 300 servers and hundreds of different databases. From just the few I'm involved with we have 10 billion records in quite a few of them with upwards of 100k new records a day and who knows how many updates... Me and a couple others need to come up with a response saying why we shouldn't do this. Most of our stuff is ASP.NET with some legacy ASP. We thought that making a simple console app that tests/times the same interactions between a flat file (stored on the network) and SQL over the network doing large inserts, searches, updates etc along with things like network disconnects randomly. This would show them how bad flat files can be especially when you are dealing with millions of records. What things should I use in my response? What should I do with my demo code to illustrate this? My sort list so far: Security Concurrent access Performance with large amounts of data Amount of time to do such a massive rewrite/switch Lack of transactions PITA to map relational data to flat files NTFS doesn't support tons of files in a directory well I fear that this will be a great post on the Daily WTF someday if I can't stop it now.

Linq is returning too many results when joined

- by KallDrexx

In my schema I have two database tables. relationships and relationship_memberships. I am attempting to retrieve all the entries from the relationship table that have a specific member in it, thus having to join it with the relationship_memberships table. I have the following method in my business object: public IList<DBMappings.relationships> GetRelationshipsByObjectId(int objId) { var results = from r in _context.Repository<DBMappings.relationships>() join m in _context.Repository<DBMappings.relationship_memberships>() on r.rel_id equals m.rel_id where m.obj_id == objId select r; return results.ToList<DBMappings.relationships>(); } _Context is my generic repository using code based on the code outlined here. The problem is I have 3 records in the relationships table, and 3 records in the memberships table, each membership tied to a different relationship. 2 membership records have an obj_id value of 2 and the other is 3. I am trying to retrieve a list of all relationships related to object #2. When this linq runs, _context.Repository<DBMappings.relationships>() returns the correct 3 records and _context.Repository<DBMappings.relationship_memberships>() returns 3 records. However, when the results.ToList() executes, the resulting list has 2 issues: 1) The resulting list contains 6 records, all of type DBMappings.relationships(). Upon further inspection there are 2 for each real relationship record, both are an exact copy of each other. 2) All relationships are returned, even if m.obj_id == 3, even though objId variable is correctly passed in as 2. Can anyone see what's going on because I've spent 2 days looking at this code and I am unable to understand what is wrong. I have joins in other linq queries that seem to be working great, and my unit tests show that they are still working, so I must be doing something wrong with this. It seems like I need an extra pair of eyes on this one :)

Android ViewFlipper is out of control

- by Doug Miller

I have an app that uses a ViewFlipper to display some text and images. I have the flipper's flipinterval set to 10 seconds, but also want to allow the user to click a button that will advance the flipper. The code blow works great on 2.2, the view is changed every 10 seconds and if I click flip_button the view is changed and the auto flip steps back in 10 seconds later. The 1.5 and 1.6 versions will remember the manual advance and it will happen every time in the rotation. What am I missing? private void initFlipButton(){ final ImageView flip_button = (ImageView) findViewById(R.id.flip_button); info_button.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { flipper.stopFlipping(); flipper.showNext(); flipper.startFlipping(); } }); } private void initFlipper(){ flipper = (ViewFlipper) findViewById(R.id.flip_dog); flipper.setFlipInterval(10000); flipper.setInAnimation(inFromRightAnimation()); flipper.setOutAnimation(outToLeftAnimation()); flipper.startFlipping(); }

PHP: Profiling code and strict environment ~ Improving my coding

- by DavidYell

I would like to update my local working environment to be stricter in an effort to improve my code. I know that my code is okay, but as with most things there is always room for improvement. I use XAMPP on my local machine, for simplicities sake Apache Friends XAMPP (Basic Package) version 1.7.2 So I've updated my php.ini : error_reporting to be E_ALL | E_STRICT to help with the code standard. I've also enabled the XDebug extension zend_extension = "C:\xampp\php\ext\php_xdebug.dll" which seems to be working, having tested some broken code and got the nice standard orange error notice. However, having read this question, http://stackoverflow.com/questions/133686/what-is-the-best-way-to-profile-php-code and enabled the profiler, I cannot seem to create a cachegrind file. Many of the guides that I've looked at seem to think you need to install XDebug in XAMPP which leads me to think they are out of date, as XDebug is bundled with XAMPP these days. So I would appreciate it if anyone can help point me in the right direction with both configuring XDebug to output grind files, and or just a great set of default settings for the XDebug config in XAMPP. Seems there is very little documentation to go on. If people have tips on integrating these tools with Netbeans, that would be awesomesauce. I'm happy to get suggestions on other things that I can do to help tighten up my php code, both syntactically and performance wise Thanks, and apologies for the rambling question(s)! Ninja edit I should menion that I'm using named vhosts as my Apache configuration, which I think is why running XDebug on port 9000 isn't working for me. I guess I'd need to edit my vhost to include port 9000

PHP programmer wanting to learn Flash game development

- by grokker

Hi! I'm currently a PHP programmer and one of my childhood dreams is to create a game. A game to show my friends or my children when the time comes :) The problem is I don't know Flash. I'm not great at drawing stuff or even artistic. I could program a little with Javascript and I could consider myself intermediate with jQuery. So my question is, how do I get started? What books do I read first? What's the steps that I should take on this journey? Thank you SO friends. I hope you all could help me create something I could be proud of :) P.S. I'm just assuming that Flash is the easiest way to create and show to other people my game. Anyway I'm very open for other suggestions! My game in mind is a side scroller about an indiana jones type of character and the setting is on the jungle with trees and snakes and a lot of animals!

I dont know how or where to add the correct encoding code to this iPhone code...

- by BC

Ok, I understand that using strings that have special characters is an encoding issue. However I am not sure how to adjust my code to allow these characters. Below is the code that works great for text that contains no special characters, but can you show me how and where to change the code to allow for the special characters to be used. Right now those characters crash the app. enter code here - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ if (buttonIndex == 1) { //iTunes Audio Search NSString *stringURL = [NSString stringWithFormat:@"http://phobos.apple.com/WebObjects/MZSearch.woa/wa/search?WOURLEncoding=ISO8859_1&lang=1&output=lm&term=\"%@\"",currentSong.title]; stringURL = [stringURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; NSURL *url = [NSURL URLWithString:stringURL]; [[UIApplication sharedApplication] openURL:url]; } } And this: -(IBAction)launchLyricsSearch:(id)sender{ WebViewController * webView = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:[NSBundle mainBundle]]; webView.webURL = [NSString stringWithFormat:@"http://www.google.com/m/search?hl=es&q=\"%@\"+letras",currentSong.title]; webView.webTitle = @"Letras"; [self.navigationController pushViewController:webView animated:YES]; } Please show me how and where to do this for these two bits of code.

Google Maps API and "rightclick" events on Macs

- by samc

Using the Google Maps API (v3), I can create a map and handle normal click events just fine, but when I want to handle rightclick events, it doesn't work on Macs. I assume this is because a rightclick on a Mac is actually converted to a ctrl-click, but the Google Maps API MouseEvent doesn't provide information about modifier keys, so I can't check for the ctrl key. I tried adding an "capture" event listener to the document that converts the click event to a rightclick event. function convertClick(e) { if (e.ctrlKey) { e.button = 2; } } document.addEventListener("click", convertClick, true) I added an alert to verify that the condition is correct, but modifying the event in this way didn't work. So, I decided to have my event handler set a global flag that my click handler could check. If the flag is set, it means ctrl was pressed, so the click handler just invokes the rightclick handler. var ctrl; function captureCtrl(e) { ctrl = e.ctrlKey; } This approach worked great, except for one thing. The ctrl flag gets set for the click after the one that occured when ctrl was pressed. That means the event handler is be called during the bubble phase rather than the capture phase. Could explain why the event modification approach didn't work. So, my question is how can you detect "rightclick" events from Macs with the Google Maps API? I can't be the first person to want to do this. That said, when I right-click on the map on http://maps.google.com from a Windows or Linux machine, I get a popup box with options like "Directions from here...", etc. On a Mac, nothing happens. So, not even the main Google Maps page has solved this problem. ...maybe I am the first person to want to do this.

Php index page utitlizing an idea for a superswitch...

- by Matt

I dont know if this is a great idea...or a crap one. But I was thinking I may use one page to display all my pages using includes. Here is what my index.php would look like...on the functions include there is a function called "superSwitch" which will determine what requested page will be included....for instance if I do a get ?a=a it will goto the function superSwitch(a) superSwitch will take it and associate it with (login.php) then respond with such... here is the code for the index.php...please let me know if this makes sense and might work, or should I just stick to long blocks of code (which is why I am trying this because I hate long pages full of code...) of course as you can tell it is not actually including anything yet...the print is for debugging purposes. :) Thanks, Matt <?php //includes Functions include_once('inc/func.inc.php'); //set superget variable $superget = @$_GET['a']; //check if superget is set or null if (!$superget) { echo "Nothing Requested :)"; } else { //sanitizes the superget request $supergetr = supergetSanitize($superget) //uses the result "good" or "nogood" to determine what happens if ( $supergetr == "good" ) { //pulls superSwitch value of the request $ssresult = superSwitch($superget); print_r ($ssresult); } //if the sanitize is nogood else { //the superSwitch is instructed to respond with a 404 page $superget = "404" $ssresult = superSwitch($superget); print_r ($ssresult); } } ?>

What would you write in a consitution (law book) for a programmers' country?

- by Developer Art

After we have got our great place to talk about professional matters and sozialize online - on SO, I believe the next logical step would be to found our own country! I invite you all to participate and bring together your available resources. We will buy an island, better even a group of island so that we could establish states like .NET territories, Java land, Linux republic etc. We will build a society of programmers (girls - we need you too). To the organizational side, we're going to need some constitution or a law book. I suggest we write it together. I make it a wiki as it should be a cooperative effort. I'll open the work. Section 1. Programmers' rights. Every citizen has a right to an Internet connection 24/7. Every citizen can freely choose the field of interest Section 2. Programmers' obligations. Every citizen must embrace the changing nature of the profession and constanly educate himself Section 3. Law enforcement. Code duplication when can be avoided is punished by limiting the bandwith speed to 64Kbit for a period of one week. Using ugly hacks instead of refactoring code is punished by cutting the Internet connection for a period of one month. Usage of technologies older than 5/10 years is punished by restricting the web access to the sites last updated 5/10 years ago for a period of one month. Please feel free to modify and extend the list. We'll need to have it ready before we proceed formally with the country foundation. A purchase fund will be established shortly.

Mercurial central server file discrepancy (using 'diff to local')

- by David Montgomery

Newbie alert! OK, I have a working central Mercurial repository that I've been working with for several weeks. Everything has been great until I hit a really bizarre problem: my central server doesn't seem to be synced to itself? I only have one file that seems to be out-of-sync right now, but I really need to know how this happened to prevent it from happening in the future. Scenario: 1) created Mercurial repository on server using an existing project directory. The directory contained the file 'mypage.aspx'. 2) On my workstation, I cloned the central repository 3) I made an edit to mypage.aspx 4) hg commit, then hg push from my workstation to the central server 5) now if I look at mypage.aspx on the server's repository using TortoiseHg's repository explorer, I see the change history for mypage.aspx -- an initial check-in and one edit. However, when I select 'Diff to local', it shows the current version on the server's disk is the original version, not the edited version! I have not experimented with branching at all yet, so I'm sure I'm not getting a branch problem. 'hg status' on the server or client returns no pending changes. If I create a clone of the server's repository to a new location, I see the same change history as I would expect, but the file on disk doesn't contain my edit. So, to recap: Central repository = original file, but shows change in revision history (bad) Local repository 'A' = updated file, shows change in revision history (good) Local repository 'B' = original file, but shows change in revision history (bad) Help please! Thanks, David

Fast sketching tools for drawing C/C++ structs, pointers, etc...

- by tomasorti

Hi. I would like to know what do you use to sketch relations between different entities in C/C++. This can be a very broad issue, so I'll try to clarify a bit more my question and give an example. I'm looking for something that is simple enough as a user, and let me sketch easily containers, pointers, etc... in an informal way. The aim is to document some structs relations to pass them to junior developers. A look at the drawings is supposed to accelerate the understanding of the code. My solutions at this moment are to use: 1) Paper & pencil. 2) Microsoft PowerPoint/Word Autoshapes. 3) Freeware Dia. Other ones could be: 4) Microsoft Visio, but my company does not own licenses. 5) UML tools. I don't want to go this way. This is what I mean a more formal solution. I know tools like Rational Rose are great, and I tried boUML and violet and they are fine in some parts, but I prefer the flexibility of options 2) or 3). Finally, let me write down a more concrete example: Let's say I what to sketch a map that contains another map as the mapped value, and that one contains a struct as the mapped value, that holds a vector of pointers of a type and a pointer to other type. Also, there exist other structs that hold pointers to the objects pointed by the previous map, so there are objects pointed from different places. This is just one example I have, but you can easily come with one from you experience. What would you use to sketch this example or another similar you have dealt with? Best regards, Tomas.

IIS not responding to the few requests from the client

- by Haroon

I am stuck with an issue with IIS 7.0. I need someone's help to find resolution on this, as this is very urgent requirement for us. Scenario I am trying to host the service in my server (Windows Server 2008 R2 and IIS 7.0) and my client is running in the XP machine with IIS 5.1. Few of my request sent from client get successful response and for few request I am getting the below exception in Visual studio when I try to debug. Exception in Visual studio 2010 An error occurred while receiving the HTTP response to This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to HTTP request context being aborted by the server (possibly due to the service shutting down). See the server logs for more details. When referred to the server event viewer log I got the below events(Application error and System warning) during the above exception. Under System logs - Warning A process serving application pool 'DefaultAppPool' suffered a fatal communication error with the Windows Process Activation Service. The process id was '5372'. The data field contains the error number. Under Application log - Error Faulting application name: w3wp.exe, version: 7.5.7600.16385, time stamp: 0x4a5bd0eb Faulting module name: ntdll.dll, version: 6.1.7600.16559, time stamp: 0x4ba9b802 Exception code: 0xc0000374 Fault offset: 0x00000000000c6df2 Faulting process id: 0x14fc Faulting application start time: 0x01cbd042562e92c3 Faulting application path: c:\windows\system32\inetsrv\w3wp.exe Faulting module path: C:\Windows\SYSTEM32\ntdll.dll Report Id: 95f76467-3c35-11e0-a46e-7071bc5cc1ee From internet I am not able to get the exact solution. Therefore could anyone please help me out from getting resolution for the same that would be really a great help for me. Please let me know if you need more details. Thanks in advance.

Django Development Environment Setup Questions

- by Ross Peoples

Hello, I'm trying to set up a good development environment for a Django project that I will be working on from two different physical locations. I have two Mac machines, one at home and one at work that I do most of my development on. I currently host a Ubuntu virtual machine on one of the machines to host the Django environemnt, install DropBox on it, and edit source code from my Mac. When I save the code file, the changes get synced over DropBox to the Ubuntu VM and the Django development server automatically restarts because of the change. This method has worked well in the past, but I am starting to use DropBox for a lot of other things now and don't want all of that to be downloaded on every virtual machine I use. Plus, I want to start using Eclipse + PyDev to be able to debug code and have code completion. Currently, I use TextEdit which is great, but doesn't support debugging or completion. So what are my options? I thought about setting up a Parallels VM on a thumb drive that has my entire environment on it (Eclipse included), but that has its own problems. Any other thoughts?
