  • When will EBS 12.2 be released?

    - by Steven Chan (Oracle Development)
    The most frequently asked question at OpenWorld this year was, "When will EBS 12.2 be released?" Sadly, Oracle's communication policies prohibit us from speculating about release dates for unreleased software. We are not permitted to give estimates, rough timelines, guesses, or anything else that remotely resembles specific guidance on release dates. You can monitor My Oracle Support and this blog for updates on EBS 12.2.  I'll post them here as soon as they're available.  I'm embedding an old favourite from 2007 in its entirety here, since it applies equally to new releases as well as certifications. "Loose Lips Sink Ships" (March 20, 2007)If I were to sort emails in my inbox into groups, the biggest -- by far -- would be the one for emails that start with, "When will _____ be certified with the E-Business Suite?"  I answer these dutifully but know that my replies can sometimes be maddening, for two reasons:  technical uncertainty, and Oracle's rules for such communications. On the Spiral Model of CertificationsTechnology stack certifications tend to be highly iterative in nature.  As a result, statements about certification dates tend to be accurate only when made in hindsight.  Laypeople are horrified to hear this, but it's the ugly truth.  Uncertainty is simply inherent to the process.  I've become inured to it over the years, but it might come as a surprise to you that it can take many cycles to get fully-released software to work together.  Take this scenario: We test a particular combination of Component A and B. If we encounter a problem, say, with Component A, we log a bug. We receive a new version of Component A. The process iterates again. The reality is this: until a certification is completed and released, there's no accurate way of telling how many iterations are yet to come.  This is true regardless of the number of iterations that have already been completed.  Our Lips Are SealedGenerally, people understand that things are subject to change, so the second reason I can't say anything specific is actually much more important than the first.  "Loose lips might sink ships" was coined in World War II in an effort to remind people that careless talk can have serious consequences.  Curiously, this applies to Oracle's communications about upcoming features, configurations, and releases, too.  As a publicly traded company, we have very strict policies that prohibit us from linking specific releases to specific dates.  If you've ever listened to an earnings call with analysts, you'll often hear them asking, "Can you add a little more color to that statement?"  For certifications, color is usually the only thing that I have.  Sometimes I can provide a bit more information about the technical nature of the certification in question, such as expected footprints or version levels.  I can occasionally share technical issues that we've found, too, to convey the degree of risk or complexity involved in the certification.  Aside from that, there's little additional information about specific dates, date ranges, or even speculation about dates that I can provide... that is, without having one of those uncomfortable conversations with Oracle Legal.  So, as much as it pains me to do so, when it comes to dates, I'm always forced to conclude with a generic reply that blandly states one of the following: We're working on that certification right now That certification is in the pipeline but hasn't been started yet We don't have plans for that certification Don't Shoot the MessengerThankfully, I've developed a thick skin over the years -- which is a good thing, considering the colorful and energetic responses I've received over the years after answering these questions.  However, on behalf of my Oracle colleagues who are faced with these questions every day in the field, I urge you to remember that they're required to follow these same corporate rules about date disclosures.  It never hurts to ask, but don't be too disappointed if we can't provide you with a detailed answer.  The Go-Go's had it right, after all.  Related Articles Webcast Replay Available: Technical Preview of EBS 12.2 Online Patching

  • Career-Defining Moments

    - by Robz / Fervent Coder
    Originally posted on: http://geekswithblogs.net/robz/archive/2013/06/25/career-defining-moments.aspx Fear holds us back from many things. A little fear is healthy, but don’t let it overwhelm you into missing opportunities. In every career there is a moment when you can either step forward and define yourself, or sit down and regret it later. Why do we hold back: is it fear, constraints, family concerns, or that we simply can't do it? I think in many cases it comes to the unknown, and we are good at fearing the unknown. Some people hold back because they are fearful of what they don’t know. Some hold back because they are fearful of learning new things. Some hold back simply because to take on a new challenge it means they have to give something else up. The phrase sometimes used is “It’s the devil you know versus the one you don’t.” That fear sometimes allows us to miss great opportunities. In many people’s case it is the opportunity to go into business for yourself, to start something that never existed. Most hold back hear for a fear of failing. We’ve all heard the phrase “What would you do if you knew you couldn’t fail?”, which is intended to get people to think about the opportunities they might create. A better term I heard recently on the Ruby Rogues podcast was “What would be worth doing even if you knew you were going to fail?” I think that wording suits the intent better. If you knew (or thought) going in that you were going to fail and you didn’t care, it would open you up to the possibility of paying more attention to the journey and not the outcome. In my case it is a fear of acceptance. I am fearful that I may not learn what I need to learn or may not do a good enough job to be accepted. At the same time that fear drives me and makes me want to leap forward. Some folks would define this as “The Flinch”. I’m learning Ruby and Puppet right now. I have limited experience with both, limited to the degree it scares me some that I don’t know much about either. Okay, it scares me quite a bit! Some people’s defining moment might be going to work for Microsoft. All of you who know me know that I am in love with automation, from low-tech to high-tech automation. So for me, my “mecca” is a little different in that regard. Awhile back I sat down and defined where I wanted my career to go and it had to do more with DevOps, defined as applying developer practices to system administration operations (I could not find this definition when I searched). It’s an area that interests me and why I really want to expand chocolatey into something more awesome. I want to see Windows be as automatable and awesome as other operating systems that are out there. Back to the career-defining moment. Sometimes these moments only come once in a lifetime. The key is to recognize when you are in one of these moments and step back to evaluate it before choosing to dive in head first. So I am about to embark on what I define as one of these “moments.”  On July 1st I will be joining Puppet Labs and working to help make the Windows automation experience rock solid! I’m both scared and excited about the opportunity!

  • Getting 2D Platformer entity collision Response Correct (side-to-side + jumping/landing on heads)

    - by jbrennan
    I've been working on a 2D (tile based) 2D platformer for iOS and I've got basic entity collision detection working, but there's just something not right about it and I can't quite figure out how to solve it. There are 2 forms of collision between player entities as I can tell, either the two players (human controlled) are hitting each other side-to-side (i. e. pushing against one another), or one player has jumped on the head of the other player (naturally, if I wanted to expand this to player vs enemy, the effects would be different, but the types of collisions would be identical, just the reaction should be a little different). In my code I believe I've got the side-to-side code working: If two entities press against one another, then they are both moved back on either side of the intersection rectangle so that they are just pushing on each other. I also have the "landed on the other player's head" part working. The real problem is, if the two players are currently pushing up against each other, and one player jumps, then at one point as they're jumping, the height-difference threshold that counts as a "land on head" is passed and then it registers as a jump. As a life-long player of 2D Mario Bros style games, this feels incorrect to me, but I can't quite figure out how to solve it. My code: (it's really Objective-C but I've put it in pseudo C-style code just to be simpler for non ObjC readers) void checkCollisions() { // For each entity in the scene, compare it with all other entities (but not with one it's already compared against) for (int i = 0; i < _allGameObjects.count(); i++) { // GameObject is an Entity GEGameObject *firstGameObject = _allGameObjects.objectAtIndex(i); // Don't check against yourself or any previous entity for (int j = i+1; j < _allGameObjects.count(); j++) { GEGameObject *secondGameObject = _allGameObjects.objectAtIndex(j); // Get the collision bounds for both entities, then see if they intersect // CGRect is a C-struct with an origin Point (x, y) and a Size (w, h) CGRect firstRect = firstGameObject.collisionBounds(); CGRect secondRect = secondGameObject.collisionBounds(); // Collision of any sort if (CGRectIntersectsRect(firstRect, secondRect)) { //////////////////////////////// // // // Check for jumping first (???) // // //////////////////////////////// if (firstRect.origin.y > (secondRect.origin.y + (secondRect.size.height * 0.7))) { // the top entity could be pretty far down/in to the bottom entity.... firstGameObject.didLandOnEntity(secondGameObject); } else if (secondRect.origin.y > (firstRect.origin.y + (firstRect.size.height * 0.7))) { // second entity was actually on top.... secondGameObject.didLandOnEntity.(firstGameObject); } else if (firstRect.origin.x > secondRect.origin.x && firstRect.origin.x < (secondRect.origin.x + secondRect.size.width)) { // Hit from the RIGHT CGRect intersection = CGRectIntersection(firstRect, secondRect); // The NUDGE just offsets either object back to the left or right // After the nudging, they are exactly pressing against each other with no intersection firstGameObject.nudgeToRightOfIntersection(intersection); secondGameObject.nudgeToLeftOfIntersection(intersection); } else if ((firstRect.origin.x + firstRect.size.width) > secondRect.origin.x) { // hit from the LEFT CGRect intersection = CGRectIntersection(firstRect, secondRect); secondGameObject.nudgeToRightOfIntersection(intersection); firstGameObject.nudgeToLeftOfIntersection(intersection); } } } } } I think my collision detection code is pretty close, but obviously I'm doing something a little wrong. I really think it's to do with the way my jumps are checked (I wanted to make sure that a jump could happen from an angle (instead of if the falling player had been at a right angle to the player below). Can someone please help me here? I haven't been able to find many resources on how to do this properly (and thinking like a game developer is new for me). Thanks in advance!

  • Don’t string together XML

    - by KyleBurns
    XML has been a pervasive tool in software development for over a decade.  It provides a way to communicate data in a manner that is simple to understand and free of platform dependencies.  Also pervasive in software development is what I consider to be the anti-pattern of using string manipulation to create XML.  This usually starts with a “quick and dirty” approach because you need an XML document and looks like (for all of the examples here, we’ll assume we’re writing the body of a method intended to take a Contact object and return an XML string): return string.Format("<Contact><BusinessName>{0}</BusinessName></Contact>", contact.BusinessName);   In the code example, I created (or at least believe I created) an XML document representing a simple contact object in one line of code with very little overhead.  Work’s done, right?  No it’s not.  You see, what I didn’t realize was that this code would be used in the real world instead of my fantasy world where I own all the data and can prevent any of it containing problematic values.  If I use this code to create a contact record for the business “Sanford & Son”, any XML parser will be incapable of processing the data because the ampersand is special in XML and should have been encoded as &amp;. Following the pattern that I have seen many times over, my next step as a developer is going to be to do what any developer in his right mind would do – instruct the user that ampersands are “bad” and they cannot be used without breaking computers.  This may work in many cases and is often accompanied by logic at the UI layer of applications to block these “bad” characters, but sooner or later someone is going to figure out that other applications allow for them and will want the same.  This often leads to the creation of “cleaner” functions that perform a replace on the strings for every special character that the person writing the function can think of.  The cleaner function will usually grow over time as support requests reveal characters that were missed in the initial cut.  Sooner or later you end up writing your own somewhat functional XML engine. I have never been told by anyone paying me to write code that they would like to buy a somewhat functional XML engine.  My employer/customer’s needs have always been for something that may use XML, but ultimately is functionality that drives business value. I’m not going to build an XML engine. So how can I generate XML that is always well-formed without writing my own engine?  Easy – use one of the ones provided to you for free!  If you’re in a shop that still supports VB6 applications, you can use the DomDocument or MXXMLWriter object (of the two I prefer MXXMLWriter, but I’m not going to fully describe either here).  For .Net Framework applications prior to the 3.5 framework, the code is a little more verbose than I would like, but easy once you understand what pieces are required:             using (StringWriter sw = new StringWriter())             {                 using (XmlTextWriter writer = new XmlTextWriter(sw))                 {                     writer.WriteStartDocument();                     writer.WriteStartElement("Contact");                     writer.WriteElementString("BusinessName", contact.BusinessName);                     writer.WriteEndElement(); // end Contact element                     writer.WriteEndDocument();                     writer.Flush();                     return sw.ToString();                 }             }   Looking at that code, it’s easy to understand why people are drawn to the initial one-liner.  Lucky for us, the 3.5 .Net Framework added the System.Xml.Linq.XElement object.  This object takes away a lot of the complexity present in the XmlTextWriter approach and allows us to generate the document as follows: return new XElement("Contact", new XElement("BusinessName", contact.BusinessName)).ToString();   While it is very common for people to use string manipulation to create XML, I’ve discussed here reasons not to use this method and introduced powerful APIs that are built into the .Net Framework as an alternative.  I’ve given a very simplistic example here to highlight the most basic XML generation task.  For more information on the XmlTextWriter and XElement APIs, check out the MSDN library.

  • How to introduce a computer illiterate 50-year old to programming [closed]

    - by sunday
    The other day my dad asked me a question that I would have never expected from him. "How can I learn C++?" My dad is turning 56 this year and computers are a distant concept for him. He doesn't know how to use a phone very well besides calling numbers (no speed dial or contacts); though he has started to learn computers a little better - to the point that he knows how to open the internet (in Windows) and browse around (and has successfully completed several job applications entirely on his own online, of which he was offered positions too). But still, these are too narrow-windowed experiences to mean much, really. While he may not have the background, my dad knows how to read. And I mean reading as a skill, not just an ability. He has little to no college education (financial problems, family, etc.) and was fortunate enough to finish high school, but still taught himself to become a master electrician and has been one for almost 30 years now. He did the same with guitar, learning to play at a very professional level and has been praised for his skill. In high school, he picked up a weight lifting book - and was the only person in his high school at the time to qualify officially as an "athlete" by national standards. In all cases, he just needed something to read. Something to teach him. He absorbs information like a sponge. I have no doubt in my dad's motivation or capability of doing this, so my general goal is simply: Get my dad into the world of computers, and get him on the road to programming. I strongly believe that once I get him through the fundamentals, his drive and reading skill will keep him going on this own. So I'm asking you all: where should I start with all this? And what are the best resources out there? Should I get him to start Linux instead of Windows? Is C++ a bad idea? Remember, he needs to (IMO) learn computers first, and then get that first grasp (the "Hello world" experience) of programming. For money's sake and at top preference, I'd like free online resources that he can read, but by all means any good suggestions in print or paid-for-online are welcome (that I could possibly look into later to purchase). And also, I intend to start him off with C++ (no Python, Java, etc.), because I know it the best and will be able to help him along the way with code. (I have minimal knowledge right now in other languages). Edit: I'm getting a lot of persistent suggestions to use Python. The only reason I wanted to do C++ is that I KNOW it and can be THERE when my dad needs help. My VERY FIRST exposure to programming ever was Java. I learned Java, and I got good at it. I open to other suggestions, but please provide an effective application of your suggestions. EDIT #2: I understand my approach/thinking/knowledge could be lacking here. I'm a sophomore level undergraduate CS major. If you don't agree with anything in my post, tell me why - give me ideas, information - that's why I'm asking in the first place. To narrow down my general goal to specific reachable goals.

  • Obtaining MFC Feature Pack GUI elements in .NET WinForms

    - by Cody Gray
    The MFC Feature Pack (and VS 2010) adds out-of-the-box support for several "modern" GUI elements (such as MDI with tabbed documents, the ribbon, and a Visual Studio-style interface with docking panels). These are a boon to those of us that have to support legacy MFC-based applications and want to update their look-and-feel, and a sign that Microsoft has not completely abandoned unmanaged C++ development. However, with the push so strongly in favor of .NET, WinForms, and managed code (and for plenty of good reasons), there seems little reason to develop new applications in unmanaged C++/MFC. The question then becomes how does one obtain these GUI elements in a WinForms application. Almost all of the add-ons and libraries I have found so far cost money, and introduce additional dependencies. I don't have a budget to buy third-party libraries, and the controls provided by Microsoft in MFC for free seem sufficient for our needs. But I still have reservations about learning MFC to develop a new application. Not only does the investment in time seem significant (by all accounts, MFC seems particularly difficult to learn, even for experienced .NET developers--although I am willing to try), but the question of MFC's lifespan is raised as well. Certainly, given the millions of lines of code and existing apps written in native C++, it will be around for some time, but the handwriting seems to be on the wall, so to speak, that it's no longer Microsoft's touted development platform. It seems like these features should be available by now in WinForms without the need for third-party add-ons, or devoting a lot of time and resources to custom-drawing EVERYTHING. Am I just missing something? I find very little online that compares these new features of MFC to what is available in WinForms, mainly because most everything written on MFC pre-dated its most recent update, before which it looked admitted "dated," and with its other flaws, was hardly an appealing platform for new development. With the very recent release of VS 2010, we have a while to wait before WinForms gets updated again. What routes are you guys taking for applications whose customers demand a modern-looking UI on a budget?

  • getting a job in game industry as a developer, just knowing a game engine

    - by numerical25
    I recently enrolled at a community college for game developement. But I am skeptical about the circulum. I have no experience in the gaming industry so I wouldnt be able to tell rather its a good investment or not. So I am asking you. I dont want to get too much into detail of all the classes I am taking so I will try to be brief. By the time I graduate, I should have a understanding of how a game engine works. I will be working with the unreal engine to develop a Multiplayer game from scratch. So in the process of my final project, I will learn how to work within the unreal engine, Learn python and learn how to use it's API to connect to a remote server and build game mechanics. Overall I will also recieve a associates degree in game development. I learn c++ but not c. The director said he was trying to implement c in the program as well. What I notice is I will not learn how to build a 3d game engine from scratch. They do not teach any AI. I will not learn how to work with the graphics card using a graphic's api such as DirectX or OpenGL. I know building a game engine from scratch is a little complex, but at the same time the track is requireing me to take some advances math courses such a calculus and geotomtry 1 and 2. I also got to take a physic class. I just think thats a little much for just learning how to use the unreal engine but not actually build one or try to learn the anatomy of a game engine. Is this good enough to possibly land my a job in the insdustry. If I left anything out or was not detail, please feel free to ask more questions. Thanks Guys!!

  • Objective-C SSL Synchronous Connection

    - by Mike
    Hello, I'm a little new to objective-C but have run across a problem that I can't solve, mostly because I'm not sure I am implementing the solution correctly. I am trying to connect using a Synchronous Connection to a https site with a self-signed certificate. I am getting the Error Domain=NSURLErrorDomain Code=-1202 "untrusted server certificate" Error that I have seen some solutions to on this forum. The solution i found was to add: - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; } (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; } to the NSURLDelegate to accept all certificates. When I connect to the site using just a: NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://examplesite.com/"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; It works fine and I see the challenge being accepted. However when I try to connect using the synchronous connection I still get the error and I don't see the challenge functions being called when I put in logging. How can I get the synchronous connection to use the challenge methods? Is it something to do with the delegate:self part of the URLConnection? I also have logging for sending/receiving data within the NSURLDelegate that is called by my connection function but not by the synchronous function. What I am using for the synchronous part: NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:@"https://examplesite.com/"]]; [request setHTTPMethod: @"POST"]; [request setHTTPBody: [[NSString stringWithString:@"username=mike"] dataUsingEncoding: NSUTF8StringEncoding]]; dataReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSLog(@"%@", error); stringReply = [[NSString alloc] initWithData:dataReply encoding:NSUTF8StringEncoding]; NSLog(@"%@", stringReply); [stringReply release]; NSLog(@"Done"); Like I mentioned I'm a little new to objective C so be kind :) Thanks for any help.

  • How to draw an Arc in OpenGL

    - by rpgFANATIC
    While making a little Pong game in C++ OpenGL, I decided it'd be fun to create arcs (semi-circles) when stuff bounces. I decided to skip Bezier curves for the moment and just go with straight algebra, but I didn't get far. My algebra follows a simple quadratic function (y = +- sqrt(mx+c)). This little excerpt is just an example I've yet to fully parameterize, I just wanted to see how it would look. When I draw this, however, it gives me a straight vertical line where the line's tangent line approaches -1.0 / 1.0. Is this a limitation of the GL_LINE_STRIP style or is there an easier way to draw semi-circles / arcs? Or did I just completely miss something obvious? void Ball::drawBounce() { float piecesToDraw = 100.0f; float arcWidth = 10.0f; float arcAngle = 4.0f; glBegin(GL_LINE_STRIP); for (float i = 0.0f; i < piecesToDraw; i += 1.0f) // Positive Half { float currentX = (i / piecesToDraw) * arcWidth; glVertex2f(currentX, sqrtf((-currentX * arcAngle)+ arcWidth)); } for (float j = piecesToDraw; j > 0.0f; j -= 1.0f) // Negative half (go backwards in X direction now) { float currentX = (j / piecesToDraw) * arcWidth; glVertex2f(currentX, -sqrtf((-currentX * arcAngle) + arcWidth)); } glEnd(); } Thanks in advance.

  • jQuery UI dialog on ASP.NET page (inside user control)

    - by marc_s
    I have a really odd behavior here: I created a little popup dialog in jQuery UI, and in my test HTML page, it works flawlessly. When I click on the button, the popup comes up, covers the background, and remains on screen until I click on one of the two buttons (OK or Cancel) provided. So now I wanted to add this into my ASP.NET 3.5 app. I wanted to add it to a GridView inside a user controls (ASCX), which is on a page (ASPX) contained inside a master page. The jQuery 1.4.2 and jQuery UI 1.8.1 scripts are referenced on the master page: <body> <form id="XXXXXX" runat="server"> <Ajax:ScriptManager ID="masterScriptManager" runat="server" ScriptMode="Auto"> <Scripts> <asp:ScriptReference Path="~/Scripts/jquery-1.4.2.min.js" /> <asp:ScriptReference Path="~/Scripts/jquery-ui-1.8.1.custom.min.js" /> </Scripts> </Ajax:ScriptManager> I had to change this to use the Ajax script manager, since adding them to the as never worked. So in my gridview, I have a column with image buttons, and when the user clicks on those, I am calling a little javascript function to show the jQuery UI dialog: function showDialog() { $("#dlg-discount").dialog('open'); $("#txtAmount").focus(); } When I run this page in MS IE 8, I get a separate page, and at the top of the page, I get the contents of my , with proper background color and all. In Firefox 3.5.6, I do get the dialog as a popup. In both cases, the dialog page/popup disappears again after a second or less - without me clicking anything! It seems similar to this question but the solution provided there doesn't work in my case. This one here also seems similar but again: the solution presented doesn't seem to work in my case... Any ideas / hints / tips on what the h** is going on here?? Thanks!

  • Creating a Custom EventAggregator Class

    - by Phil
    One thing I noticed about Microsoft's Composite Application Guidance is that the EventAggregator class is a little inflexible. I say that because getting a particular event from the EventAggregator involves identifying the event by its type like so: _eventAggregator.GetEvent<MyEventType>(); But what if you want different events of the same type? For example, if a developer wants to add a new event to his application of type CompositePresentationEvent<int>, he would have to create a new class that derives from CompositePresentationEvent<int> in a shared library somewhere just to keep it separate from any other events of the same type. In a large application, that's a lot of little two-line classes like the following: public class StuffHappenedEvent : CompositePresentationEvent<int> {} public class OtherStuffHappenedEvent : CompositePresentationEvent<int> {} I don't really like that approach. It almost feels dirty to me, partially because I don't want a million two-line event classes sitting around in my infrastructure dll. What if I designed my own simple event aggregator that identified events by an event ID rather than the event type? For example, I could have an enum such as the following: public enum EventId { StuffHappened, OtherStuffHappened, YetMoreStuffHappened } And my new event aggregator class could use the EventId enum (or a more general object) as a key to identify events in the following way: _eventAggregator.GetEvent<CompositePresentationEvent<int>>(EventId.StuffHappened); _eventAggregator.GetEvent<CompositePresentationEvent<int>>(EventId.OtherStuffHappened); Is this good design for the long run? One thing I noticed is that this reduces type safety. In a large application, is this really as important of a concern as I think it is? Do you think there could be a better alternative design?

  • WPF relaycommand from usercontrol

    - by pilsdumps
    Hi, I'm new to WPF and in the spirit of trying to do things the correct way have tried to implement MVVM in my application. I've made use of the frequently mentioned article by Josh Smith, and apart from making me realise how little I know, it has left me a little stumped. Specifically, I have a page that uses the RelayCommand object to handle a button directly on the page and this is fine. However, the button (save) will ultimately be on a user control that will also contain other buttons and the control will be used on a number of pages. My question is this; how do I relay the command from the user control to the page (ie viewmodel) containing it? If I bind to the command public ICommand SaveCommand { get { if (_saveCommand == null) { _saveCommand = new RelayCommand( param => this.Save(), param => this.CanSave ); } return _saveCommand; } } on the user control, I would need to use a Save method on the user control itself, when in fact I should be handling it on the viewmodel. Can anyone help?

  • Finding begin and end of year/month/day/hour

    - by reto
    I'm using the following snipped to find the begin and end of several time periods in Joda. The little devil on my left shoulder says thats the way to go... but I dont believe him. Could anybody with some joda experience take a brief look and tell me that the little guy is right? (It will be only used for UTC datetime objects) Thank you! /* Year */ private static DateTime endOfYear(DateTime dateTime) { return endOfDay(dateTime).withMonthOfYear(12).withDayOfMonth(31); } private static DateTime beginningOfYear(DateTime dateTime) { return beginningOfMonth(dateTime).withMonthOfYear(1); } /* Month */ private static DateTime endOfMonth(DateTime dateTime) { return endOfDay(dateTime).withDayOfMonth(dateTime.dayOfMonth().getMaximumValue()); } private static DateTime beginningOfMonth(DateTime dateTime) { return beginningOfday(dateTime).withDayOfMonth(1); } /* Day */ private static DateTime endOfDay(DateTime dateTime) { return endOfHour(dateTime).withHourOfDay(23); } private static DateTime beginningOfday(DateTime dateTime) { return beginningOfHour(dateTime).withHourOfDay(0); } /* Hour */ private static DateTime beginningOfHour(DateTime dateTime) { return dateTime.withMillisOfSecond(0).withSecondOfMinute(0).withMinuteOfHour(0); } private static DateTime endOfHour(DateTime dateTime) { return dateTime.withMillisOfSecond(999).withSecondOfMinute(59).withMinuteOfHour(59); }

  • Achieving NHibernate Nested Transactions Behavior

    - by jfneis
    Hi all, I'm trying to achieve some kind of nested transaction behavior using NHibernate's transaction control and FlushMode options, but things got a little bit confusing after too much reading, so any confirmation about the facts I list below will be very usefull. What I want is to open one big transaction that splits in little transactions. Imagine the following scenario: TX1 opens a TX and inserts a Person's record; TX2 opens a TX and updates this Person's name to P2; TX2 commits; TX3 opens a TX and updates this Person's name to P3; TX3 rollbacks; TX1 commits; I'd like to see NH sending the INSERT and the TX2 UPDATE to the database, just ignoring what TX3, as it was rolled back. I tried to use FlushMode = Never and only flushing the session after the proper Begins/Commits/Rollbacks have been demanded, but NH always update the database with the object's final state, independent of commits and rollbacks. Is that normal? Does NH really ignores transactional control when working with FlushMode = Never? I've also tried to use FlushMode = Commit and openning the nested transactions, but I discovered that, because ADO.NET, the nested transactions are, actually, always the same transaction. Note that I'm not trying to achieve a "all or nothing" behavior. I'm looking more to a savepoint way of working. Is there a way to do that (savepoints) with NH? Thank you in advance. Filipe

  • IKImageView resize is blocky

    - by Brian Postow
    I am putting an image into an IKImageView, and immediately sizing it to fit. Whenever I do this, the image originally appears at 1-1 size (huge) and then resizes down, which would be fine if the animation was smooth. However, the animation looks ... fluttery? There are big blocks, like 2 inches square, of the image that appear and shrink independently of each other. The effect is a little annoying, and almost to the level where it might give an epileptic a seizure... (I'm exaggerating a little). Is this a bug in IKImageView? Is it a bug in the animation? Will it go away if I turn off the animation (How do I do that? setAnimates: NO doesn't seem to do anything, nor does overloading animates to return NO in my subclass... EDIT: addedcode: NSImage* image = [doc currentImage]; [imageView setImage: image]; [imageView zoomImageToFit: self]; This is in the app controller, so self is the application (or plugin, depending on which version I'm looking at)

  • Some JPEG images are not working in IE

    - by jwandborg
    Hello, I have a press archive. The press archive displays automattically created thumbnails as links to a PDF document. This is what i get in IE 6, 7 & 8: While it works fine in Chrome: The thumbnails are automatically created by imagemagick: $cmd = 'convert ' . $_FILES['file']['tmp_name'] # This is a PDF file . '[0]' # This indicates that it the first page that should be converted . ' -resize "120x120" ' # This is the size of the thumbnail . $thumb_path; # This is the destination $resize_output = exec($cmd); A command can look like this convert /tmp/AcXDYe[0] -resize "120x120>" /var/www[...] However I looked a little closer on the images and it seems that they are a little different and this is a theme among all the failing images Image that does'nt work in IE: http://regex.info/exif.cgi?url=http://bit.ly/aFTL3T Image that works fine: http://regex.info/exif.cgi?url=http://bit.ly/b71B7R So, can i change my imagemagick command so that creates IE-compatible JPEGS?

  • Yet another Subversion "Commit failed" MERGE of 'blabla': 200 OK

    - by marty3d
    Hi! I get the infamous "MERGE of 'whatever': 200 OK" whenever I try to commit using a post-commit hook on Windows (running the repository and Trac locally), and I'm going crazy. I've been looking all over for a day now, without finding any solutions. So here's how it's set up and what I've tried so far: Settings: Windows 7 (64-bit) VisualSVN Server TortoiseSVN Trac 0.11.6 I'm using the three standard scripts for post-commit on Windows. Everything works when I run post-commit.cmd from the command prompt with repo and changesetnumber as parameters. After extensive trouble-shooting, I found that if I remove the last line in trac-post-commit.cmd, Python "%~dp0\trac-post-commit-hook.py" -p "%TRAC_ENV%" -r "%REV%" -u "%AUTHOR%" -m "%LOG%", the Commit failed error goes away. Adding 1/0 (generating a division by zero error) in the python script doesn't show anything different. From the command prompt I get an error, though. Removing all code in the python script also makes the commit failed go away, so I guess the culprit is in trac-post-commit-hook.py. Perhaps if I could send the actual error to a log file, I could dig a little deeper, but I'm not sure how. post-commit.cmd: call %~dp0\trac-post-commit-hook.cmd %1 %2 trac-post-commit-hook.cmd: http://trac.edgewall.org/browser/trunk/contrib/trac-post-commit-hook?rev=920 Thank you so much, it would mean alot if someone could assist a little here! /Martin

  • Roadmap to Android development

    - by Matthew
    Hello, I've done a little research, and am interested in developing for Android. I've never programmed before, and have no idea how to go from zero experience to developing for a mobile device. My interest is in eventually making some sort of 2d game. Is there a lesson plan for starting from the ground up? I would think one would need to learn the Java language to start. Looking at the Sun website, it's a bit daunting. Is there a book, specifically, that would wrap up this knowledge in a bit of a directed lesson plan? I'm not sure if opengl-es is what would be required for 2d games. I've done a little research on this, and it's even far more daunting than Java itself. I can't even begin to figure out where to start with even just opengl, sans -es. My best guess would be that I need further knowledge in Java to continue with this, but even still, is it possible to learn concurrently with Java?

  • Confused about C++'s std::wstring, UTF-16, UTF-8 and displaying strings in a windows GUI

    - by dfrey
    I'm working on a english only C++ program for Windows where we were told "always use std::wstring", but it seems like nobody on the team really has much of an understanding beyond that. I already read the question titled "std::wstring VS std::string. It was very helpful, but I still don't quite understand how to apply all of that information to my problem. The program I'm working on displays data in a Windows GUI. That data is persisted as XML. We often transform that XML using XSLT into HTML or XSL:FO for reporting purposes. My feeling based on what I have read is that the HTML should be encoded as UTF-8. I know very little about GUI development, but the little bit I have read indicates that the GUI stuff is all based on UTF-16 encoded strings. I'm trying to understand where this leaves me. Say we decide that all of our persisted data should be UTF-8 encoded XML. Does this mean that in order to display persisted data in a UI component, I should really be performing some sort of explicit UTF-8 to UTF-16 transcoding process? I suspect my explanation could use clarification, so I'll try to provide that if you have any questions.

  • UML class diagram vs ER database diagram

    - by salva84
    Hi, I'm a little confused, I'm developing a program, the program consist in two parts, the server and the clients, there are groups, places, messages... stored in the server, and the clients has to connect with it. I've design the use cases diagram, the activity diagrams, and I have design the class diagram too. The thing is that I want to implement the server in a mysql tables for storing the users, groups, places... users in groups... so I've designed a E-R diagram consisting in 6 tables, but the problem is that I think that my class diagram and my ER diagram looks too similar, I mean, I think I'm not doing things right because I have a class for each table practically, and when I have to extract all the users on my system, do I have to convert all the rows into objects at first and write in the database for each object modified? The easy choice for me would be to base my whole application only in the database, and making a class to extract and insert data in it, but I have to follow the UML specification and I'm a little confused what to do with the class diagram, because the books I have read say that I have to create a class for each "entity" of my program. Sorry for my bad English. Thank you.

  • IPhone SDK - Transition to NavigationController display problem

    - by Steblo
    Hi, I am nearly finished with my first IPhone app and everything works fine - except of one very little display bug: My starscreen is an UIView (Fullscreen) without Navigationbar or Toolbar. If I tap on a start button, there is an UIViewAnimationTransitionFlipFromRight animation that flips to the main navigation controller: -(IBAction) switchViewToMainMenu { [UIView beginAnimations:@"Flip View" context:nil]; [UIView setAnimationDuration:1.25]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:self.window cache:YES]; [self.navController viewWillAppear:YES]; [self.startScreenViewController viewWillDisappear:YES]; [self.startScreenViewController.view removeFromSuperview]; [self.window addSubview:navController.view]; [self.startScreenViewController viewDidDisappear:YES]; [self.navController viewDidAppear:YES]; [UIView commitAnimations]; self.startScreenViewController=nil; [startScreenViewController release]; } This works fine except of one little problem: When the navigation controller view appears (flips in), the Navigationbar on top is some pixels too high (the is a white bar where the Navigationbar should be). When the animation finished, the Navigationbar drops down to the right position. This doesn't look very beautiful... Any ideas how to fix that problem ?

  • Python coding test problem for interviews

    - by Kal
    I'm trying to come up with a good coding problem to ask interview candidates to solve with Python. They'll have an hour to work on the problem, with an IDE and access to documentation (we don't care what people have memorized). I'm not looking for a tough algorithmic problem - there are other sections of the interview where we do that kind of thing. The point of this section is to sit and watch them actually write code. So it should be something that makes them use just the data structures which are the everyday tools of the application developer - lists, hashtables (dictionaries in Python), etc, to solve a quasi-realistic task. They shouldn't be blocked completely if they can't think of something really clever. We have a problem which we use for Java coding tests, which involves reading a file and doing a little processing on the contents. It works well with candidates who are familiar with Java (or even C++). But we're running into a number of candidates who just don't know Java or C++ or C# or anything like that, but do know Python or Ruby. Which shouldn't exclude them, but leaves us with a dilemma: On the one hand, we don't learn much from watching someone struggle with the basics of a totally unfamiliar language. On the other hand, the problem we use for Java turns out to be pretty trivial in Python (or Ruby, etc) - anyone halfway competent can do it in 15 minutes. So, I'm trying to come up with something better. Surprisingly, Google doesn't show me anyone doing something like this, unless I'm just too dumb to enter the obvious search term. The best idea I've come up with involves scheduling workers to time slots, but it's maybe a little too open-ended. Have you run into a good example? Or a bad one? Or do you just have an idea?

  • Using inotify-tools and ruby to push uploads to Cloud Files

    - by Christian
    Hi Guys, I wrote a few scripts to monitor an uploads directory for changes, then capture the file uploaded/changed and push it to cloud files using a ruby script. This all works well 95% of the time, the only exception is that occasionally, ruby fails with a 'file does not exist' exception. I am assuming that the ruby 'push' script is being called before the file is 100% in its new location, so the script is being called a little prematurely. I tried adding a little function to my script to check if the file exists, if it doesn't, sleep 5 then try again, but this seems to snowball and eventually dies. I then just added a sleep 2 to all calls, but it hasn't helped as I now get the 'file does not exist' error again. #!/bin/sh function checkExists { if [ ! -e "$1" ] then sleep 5 checkExists $1 fi } inotifywait -mr --timefmt '%d/%m/%y-%H:%M' --format '%T %w %f' -e modify,moved_to,create,delete /home/skylines/html/forums/uploads | while read date dir file; do cloudpath=${dir:20}${file} localpath=${dir}${file} #checkExists $localpath sleep 2 ruby /home/cbiggins/bin/pushToCloud.rb skylinesaustralia.com $cloudpath $localpath echo "${date} ruby /home/cbiggins/bin/pushToCloud.rb skylinesaustralia.com $cloudpath $localpath" >> /var/log/pushToCloud.log done I am looking for any suggestions to help me make this 100% stable (eventually, I'll serve the uploaded files from Cloud FIles, so I need to make sure its perfect) Thanks in advance!

  • Does RabbitMq do round-robin from the exchange to the queues

    - by Lancelot
    Hi, I am currently evaluating message queue systems and RabbitMq seems like a good candidate, so I'm digging a little more into it. To give a little context I'm looking to have something like one exchange load balancing the message publishing to multiple queues. I don't want to replicate the messages, so a fanout exchange is not an option. Also the reason I'm thinking of having multiple queues vs one queue handling the round-robin w/ the consumers, is that I don't want our single point of failure to be at the queue level. Sounds like I could add some logic on the publisher side to simulate that behavior by editing the routing key and having the appropriate bindings in place. But that's kind of a passive approach that wouldn't take the pace of the message consumption on each queue into account, potentially leading to fill up one queue if the consumer applications for that queue are dead. I was looking for a more pro-active way from the exchange entity side, that would decide where to send the next message based on each queue size or something of that nature. I read about Alice and the available RESTful APIs but that seems kind of a heavy duty solution to implement fast routing decisions. Anyone knows if round-robin between the exchange the queues is feasible w/ RabbitMQ then? Thanks.
