  • MDM Poised for Growth

    - by david.butler(at)oracle.com
    David Nixon, an Oracle colleague of mine, was doing some research on MDM the other day. He came up with some well founded insights that I thought I’d share with you. Gartner recently published a note asking “Should Organizations Using ERP 'Do' Master Data Management?”  It may seem a bit strange but that’s a question Gartner has been asked by a number of companies as organizations are beginning to understand the importance of data governance and data stewardship.  That’s because ERP Suites typically “focus on integrating their own applications within suites, but have little interest in making their suites interoperate with the applications or suites of other vendors.”  Therefore, Gartner is advising customers that “have deployed or plan to support multiple packaged application suites (even from the same vendor) that have different semantic data and/or process models” to add an MDM solution. And it appears that customers are taking note.  In a more recent note entitled “Search Analytics Trends: Master Data Management”, Gartner noted that MDM searches on gartner.com in November 2010 “were 300% higher than [in] May 2009, indicating the increased interest an importance that businesses are placing on MDM.”  Why the increased interest?  Moving towards a single version of the truth is a familiar theme, but customers are talking more about the underlying business value that this enables.  For example, businesses are talking about the need to fix master data before they can successfully move forward on SOA initiatives.  And the growing demands for compliance continue to be a major driver.  In short, companies are talking more about specific and tangible business value, and they are looking for help creating business cases for an MDM initiative. Why This Matters Gartner’s notes make three things clear.  First, MDM is poised for growth as organizations gain a greater understanding for it and the need they have.  Many are still sorting it out, but the demand is growing and is sure to rise.  Second, any organization with a heterogeneous computing environment should invest in MDM.  Even solutions from the same vendor may have different data models and could benefit from MDM.  But the key to growth, or which vendors will benefit the most from it, is the third and perhaps most critical point: companies need help with the business case for MDM. Oracle can help your organization build a compelling business case for MDM. We have seen our 1100+ MDM customers gain competitive advantages in a wide variety of implementations. Give us a ring.

  • Cooking with Wessty: WordPress and HTML 5

    - by David Wesst
    WordPress is easily one, if not the most, popular blogging platforms on the web. With the release of WordPress 3.x, the potential for what you can do with this open source software is limitless. This technique intends to show you how to get your WordPress wielding the power of the future web, that being HTML 5. --- Ingredients WordPress 3.x Your favourite HTML 5 compliant browser (e.g. Internet Explorer 9) Directions Setup WordPress on your server or host. Note: You can setup a WordPress.com account, but you will require an paid add-on to really take advantage of this technique.Login to the administration panel. Login to the administration section of your blog, using your web browser.  On the left side of the page, click the Appearance heading. Then, click on Themes. At the top of the page, select the Install Themes tab. In the search box, type the “toolbox” and click search. In the search results, you should see an theme called Toolbox. Click the Install link in the Toolbox item. A dialog window should appear with a sample picture of what the theme looks like. Click on the Install Now button in the bottom right corner. Et voila! Once the installation is done, you are done and ready to bring your blog into the future of the web. Try previewing your blog in HTML 5 by clicking the preview link.   Now, you are probably thinking “Man…HTML 5 looks like junk”. To that, I respond: “HTML was never why your site looked good in the first place. It was the CSS.” Now you have an un-stylized theme that uses HTML 5 elements throughout your WordPress site. If you want to learn how to apply CSS to your WordPress blog, you should check out the WordPress codex that pretty much covers everything there is to cover about WordPress development. Now, remember how we noted earlier that your free WordPress.com account wouldn’t take advantage of this technique? That is because, as of the time of this writing, you needed to pay a fee to use custom CSS. Remember now, this only gives you the foundation to create your own HTML 5 WordPress site. There are some HTML 5 themes out there that already look good, and were built using this as the foundation and added some CSS 3 to really spice it up. Looking forward to seeing more HTML 5 WordPress sites! Enjoy developing the future of the web.

  • How to keep groups when pulling with git

    - by mimrock
    I have a staging site that is a working directory of a git repository. How to set up git to let a developer pull out a branch or release without changing the group of the modified files? An example. Let's say I have two developers, robin and david. They are both in git-users group, so initially they can both have write permissions on site.php. -rw-rw-r-- 1 robin git-users 46068 Nov 16 12:12 site.php drwxrwxr-x 8 robin git-users 4096 Nov 16 14:11 .git After robin-server1$ git pull origin master: -rw-rw-r-- 1 robin robin 46068 Nov 16 12:35 site.php drwxrwxr-x 8 robin git-users 4096 Nov 16 14:11 .git And david do not have write permissions on site.php, because the group changed from 'git-users' to 'robin'. From now on, david will get a permission denied, when he tries to pull to this repository.

  • Learn Domain-Driven Design

    - by Ben Griswold
    I just wrote about how I like to present on unfamiliar topics. With this said, Domain-Driven Design (DDD) is no exception. This is yet another area I knew enough about to be dangerous but I certainly was no expert.  As it turns out, researching this topic wasn’t easy. I could be wrong, but it is as if DDD is a secret to which few are privy. If you search the Interwebs, you will likely find little information about DDD until you start rolling over rocks to find that one great write-up, a handful of podcasts and videos and the Readers’ Digest version of the Blue Book which apparently you must read if you really want to get the complete, unabridged skinny on DDD.  Even Wikipedia’s write-up is skimpy which I didn’t know was possible…   Here’s a list of valuable resources.  If you, too, are interested in DDD, this is a good starting place.  Domain-Driven Design: Tackling Complexity in the Heart of Software by Eric Evans Domain-Driven Design Quickly, by Abel Avram & Floyd Marinescu An Introduction to Domain-Driven Design by David Laribee Talking Domain-Driven Design with David Laribee Part 1, Deep Fried Bytes Talking Domain-Driven Design with David Laribee Part 2, Deep Fried Bytes Eric Evans on Domain Driven Design, .NET Rocks Domain-Driven Design Community Eric Evans on Domain Driven Design Jimmy Nilsson on Domain Driven Design Domain-Driven Design Wikipedia What I’ve Learned About DDD Since the Book, Eric Evans Domain Driven Design, Alt.Net Podcast Applying Domain-Driven Design and Patterns: With Examples in C# and .NET, Jimmy Nilsson Domain-Driven Design Discussion Group DDD: Putting the Model to Work by Eric Evans The Official DDD Site

  • Outstanding Silverlight User Group Meeting last night

    - by Dave Campbell
    We had a great Silverlight User Group Meeting in Phoenix last night! Before I go any farther I want to say thanks again to David Silverlight and Kim Schmidt for coming to talk to us! And not to forget Victor Gaudioso over the wire :) David, Kim, and Victor talked to us about the Silverlight User Group Starter Kit they are working on with an extended stellar list of talented developers. Don't bypass looking at this by thinking it's only for a User Group... this is a solid community-supported full-up application using MVVM and Ria Services that you could take and modify for your own use. Take a look at the list of developers. Chances are you know some of them... send them an email of thanks for all the hard work over the last year! David and Kim discussed the architecture and code, demonstrating features as they went. Then Victor came in through the application itself on a high-intensity live webcast from his home in California. The audience of about 15 seemed focused and interested which says a lot about the subject and presentation. Tim Heuer came bearing some gifts (swag) ... a hard-copy of Josh Smith's Advanced MVVM , and couple cheaply upgradeable copies of VS2008 Pro that were snatched up very quickly. We also gave away a few copies of Windows 7 Ultimate 64-bit, some Arc mice, and some Office 2007 disks... so I don't think anyone left empty-handed. Personal thanks from me go out to Mike Palermo and Tim Heuer for the surprise they had waiting for me that's been over Twitter, and to Victor for only mentioning it at least 3 times in a 5-minute webcast. Thanks for a great evening, and I look forward to seeing all of you in a couple weeks at MIX10!

  • NSDictionary - Read BOOL from Internet-Downloaded Plist

    - by David Schiefer
    Hi, I am downloading a PLIST file from my server using NSURLDownload. Once it is downloaded, I read the file using NSDictionary's dictionaryWithContentsOfFile: method. I need to read a BOOL value, so this is my code: if ([dict objectForKey:string] == [NSNumber numberWithBool:YES]) This however always returns NO, no matter what the value is. The same happens if I replace the == with isEqual:. Am I doing this wrong?

  • MobileMe Connection - Cocoa

    - by David Schiefer
    Hi, I need to send a file to MobileMe via Cocoa. I stumbled across a .Mac framework from Apple but it hasn't been updated in years, so I don't want to use it due to possible compatibility problems it may cause. I think that the MobileMe.framework is private, so I don't think I can use it. What kind of alternatives are there available for me so that I can upload the file to MobileMe? I've also been looking into WebDav frameworks (since MobileMe is WebDav based), but I didn't find anything useful either. Thanks!

  • iphone calls both if and else at the same time?

    - by David Schiefer
    Hi, I need to determine what file type a file is and then perform a certain action for it. this seems to work fine for some types, however all media types such as videos and sound files get mixed up. I determine the file type by doing this: BOOL matchedMP3 = ([[rowValue pathExtension] isEqualToString:@"mp3"]); if (matchedMP3 == YES) { NSLog(@"Matched MP3"); } I do this for various file types and just define an "else" for all the others. Here's the problem though. The iPhone calls them both. Here's what the log reveals: 2010-05-11 18:51:12.421 Test [5113:207] Matched MP3 2010-05-11 18:51:12.449 Test [5113:207] Matched ELSE I've never seen anything like this before. This is my "matchedMP3" function: BOOL matchedMP3 = ([[rowValue pathExtension] isEqualToString:@"mp3"]); if (matchedMP3 == YES) { NSLog(@"Matched MP3"); NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSFileManager *manager = [NSFileManager defaultManager]; self.directoryContent = [manager directoryContentsAtPath:documentsDirectory]; NSString *errorMessage = [documentsDirectory stringByAppendingString:@"/"]; NSString *urlAddress = [errorMessage stringByAppendingString:rowValue]; MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:urlAddress]]; moviePlayer.movieControlMode = MPMovieControlModeDefault; moviePlayer.backgroundColor = [UIColor blackColor]; [moviePlayer play]; } and here's the else statement: else { NSLog(@"Matched ELSE"); [[NSUserDefaults standardUserDefaults] setObject:rowValue forKey:@"rowValue"]; NSString*rowValue = [[NSUserDefaults standardUserDefaults] objectForKey:@"rowValue"]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSFileManager *manager = [NSFileManager defaultManager]; self.directoryContent = [manager directoryContentsAtPath:documentsDirectory]; NSString *errorMessage = [documentsDirectory stringByAppendingString:@"/"]; NSString *urlAddress = [errorMessage stringByAppendingString:rowValue]; webViewHeader.prompt = rowValue; [documentViewer setDelegate:self]; NSString *encodedString = [urlAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; //Create a URL object. NSURL *url = [NSURL URLWithString:encodedString]; //URL Requst Object NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; //Load the request in the UIWebView. [documentViewer loadRequest:requestObj]; [navigationController pushViewController:webView animated:YES]; } I can't see a reason why it wouldn't work. What happens is that both the webview and the MediaPlayer toggle their own player, so they overlap and play their sound/video a few secs apart from each other. Any help would be appreciated & thank for you taking the time to read through my code.

  • IE9 and the Mystery of the Broken Video Tag

    - by David Wesst
    I was very excited when Microsoft released the Internet Explorer 9 Release Candidate. As far as I was concerned, this was another nail in the coffin for IE6 and step in the right direction for us .NET web developers as our base camp was finally starting to support the latest and greatest future-web standards. Unfortunately, my celebration was short lived as I soon hit a snag while loading up an HTML5 site I was building in Visual Studio 2010. The Mystery After updating Internet Explorer, I ran my HTML5 site that had the oh-so-lovely HTML5 video tag showing a video. Even though this worked in IE9 Beta, it appeared that IE9 RC could not load the same file. I figured that it was the video codec. Maybe IE9 RC no longer supported the video codec I used to encode my video. Here's the code I used: <video width="854" height="480" id="myOtherVideo" autoplay="" controls=""> <source src="/DemoSite1/Media/big_buck_bunny.mp4"/> <div> <p>Your browser does not support HTML5 Video.</p> </div> </video> As you can see from the code, I had the "fail-safe" code inside the video tag. The idea there being that if the video tag, or the video files themselves, are not supported by the browser my video should fail gracefully. What was even more strange was the fact that it worked in all the other HTML5 browsers that supported video. The Investigation Whoa! DJ stop the music. How can any of that make sense? Would the IE team really take such huge strides forward only to forget to include a feature that was already in the beta? I don't think so. I did plenty of searching on the web and asking around on the web, but could not seem to find anyone else having the same problem. Eventually I came across this post talking about declaring the MIME type in the .htaccess file. That got me thinking: does my web server support the video MIME type? I was using VS2010, so how do I know what kind of MIME types are supported by default? Still, my page hosted in Cassini (the web development server in VS2010) works on the other browsers. Why wouldn't it work with IE9 RC? To answer that, it was time to open up the upgraded toolbox known as the Developer's Tools in IE9 and use the new Network Tab. The Conclusion If you take a closer look at the results displayed from the Network tab, you can see that IE9 RC has interpreted the video file as text/html rather than video/mp4. To make this work, I decided to use IIS to debug my HTML5 web application by setting the web project's properties. Then, I added the MIME types that I want to support (i.e. video/mp4, video/ogg, video/webm). Et voila! The Mystery of the Broken Video Tag is solved. After Thoughts After solving the mystery, I still had the question about why my site worked in Chrome, Safari, and Firefox 3.6. After asking around, the best answer that I received was from my colleague Tyler Doerksen. He said that IE9 likely depends on the server telling it what kind of file it is downloading rather than trying to read the metadata about the data it is trying to download before doing anything. I have no facts to back this up, but it makes sense to me. In a browser war where milliseconds can make your browser fall back a few places in the race for supremacy, maybe the IE team opted to depend on the server knowing what kind of content it is serving up. Makes sense to me. In any case, that is just an educated guess. If you have any comments, feel free to post on them below. This post also appears at http://david.wes.st

  • 5 Ways to Celebrate the Release of Internet Explorer 9

    - by David Wesst
    The day has finally come: Microsoft has released a web browser that is awesome. On Monday night, Microsoft officially introduced the world to the latest edition to its product family: Internet Explorer 9. That makes March 14, 2011 (also known as PI day) the official birthday of Microsoft’s rebirth in the world of web browsing. Just like any big event, you take some time to celebrate. Here are a few things that you can do to celebrate the return of Internet Explorer. 1. Download It If you’re not a big partier, that’s fine. The one thing you can do (and definitely should) is download it and give it a shot. Sure, IE may have disappointed you in the past, but believe me when I say they really put the effort in this time. The absolute least you can do is give it a shot to see how it stands up against your favourite browser. 2. Get yourself an HTML5 Shirt One of the coolest, if not best parts of IE9 being released is that it officially introduces HTML5 as a fully supported platform from Microsoft. IE9 supports a lot of what is already defined in the HTML5 technical spec, which really demonstrates Microsoft’s support of the new standard. Since HTML5 is cool on the web, it means that it is cool to wear it too. Head over to html5shirt.com and get yourself, or your staff, or your whole family, an HTML5 shirt to show the real world that you are ready for the future of the web. 3. HTML5-ify Something Okay, so maybe a shirt isn’t enough for you. Maybe you need start using HTML5 for real. If you have a blog, or a website, or anything out there on the web, celebrate IE9 adding some HTML5 to your site. Whether that is updating old code, adding something new, or just changing your WordPress theme, definitely take a look at what HTML5 can do for you. 4. Help Kill Old IE and Upgrade your Organization See this? This is sad. Upgrading web browsers in an large enterprise or organization is not a trivial task. A lot of companies will use the excuse of not having the resources to upgrade legacy web applications they were built for a specific version of IE and it doesn’t render correctly in legacy browsers. Well, it’s time to stop the excuses. IE9 allows you to define what version of Internet Explorer you would like it to emulate. It takes minimal effort for the developer, and will get rid of the excuses. Show your IT manager or software development team this link and show them how easy it is to make old code render right in the latest and greatest from the IE team. 5. Submit an Entry for DevUnplugged So, you’ve made it to number five eh? Well then, you must be pretty hardcore to make it this far down the list. Fine, let’s take it to the next level and build an HTML5 game. That’s right. A game. Like a video game. HTML5 introduces some amazing new features that can let you build working video games using HTML5, CSS3, and JavaScript. Plus, Microsoft is celebrating the launch of IE9 with a contest where you can submit an HTML5 game (or audio application) and have a chance to win a whack of cash and other prizes. Head here for the full scoop and rules for the DevUnplugged. This post also appears at http://david.wes.st

  • CORE Keygen Problem

    - by David Schiefer
    Hi, after fighting several versions of the CoreKeyGen created by some "minamoto" guy, a new version has appeared. This version is particularly sophisticated and seems to modify the actual binary itself, using a dylib known as libbassmod.dylib (this is in the keygen's mac os folder). Has anyone ever come across this & can give me advice on how to stop it? If so, how can I stop the keygen? it seems like the library can see what calls my app makes and stop them somehow, I'm not too sure.

The *plist file is never written. What am I doing wrong?

  • Creating a Cocoa Framework

    - by David Schiefer
    Hi, I've created a working Cocoa framework which I wish to redistribute. The problem is however, it won't run outside of Xcode. I've read something about @executable_path/../Frameworks, which I did not include, because I don't know where to put it :/ Therefore I run my app in Xcode using the DYLD_FRAMEWORK_PATH variable which works fine, but only in Xcode - if I try to run it on its own it crashes straight away and says IMAGE NOT FOUND. I'm sure @executable_path/../Frameworks is what's missing, but I don't know where to put it. Could anyone help me out please? :) Thanks

    Possible Duplicate: NSNumberFormatter and ‘th’ ‘st’ ‘nd’ ‘rd’ (ordinal) number endings Hello, I'm building an application that downloads player ranks and displays them. So say for example, you're 3rd out of all the players, I inserted a condition that will display it as 3rd, not 3th and i did the same for 2nd and 1st. When getting to higher ranks though, such as 2883rd, it'll display 2883th (for obvious reasons) My question is, how can I get it to reformat the number to XXX1st, XXX2nd, XXX3rd etc? To show what I mean, here's how I format my number to add a "rd" if it's 3 if ([[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] isEqualToString:@"3"]) { NSString*badge = [NSString stringWithFormat:@"%@rd",[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; NSString*scoreText = [NSString stringWithFormat:@"ROC Server Rank: %@rd",[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; profile.badgeValue = badge; rank.text = scoreText; } I can't do this for every number up to 2000 (there are 2000 ranks in total) - what can I do to solve this problem?

Properties.h: [[NSNotificationCenter defaultCenter] postNotificationName:@"NameChanged" object:[WriteIt_MobileAppDelegate class] userInfo:nil]; WriteIt_MobileAppDelegate.m -(void)awakeFromNib { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reloadItProperties:) name:@"NameChanged" object:self]; } - (void) reloadItProperties: (NSNotification *)notification { NSLog(@"Reloading Data"); //this gets called [self.navigationController popToRootViewControllerAnimated:YES]; [self.tblSimpleTable reloadData]; [self.tblSimpleTable reloadSectionIndexTitles]; // but the rest doesn't } What am I doing wrong here?

  • iPhone Simulator - Restores Plist - Weird Issue

    - by David Schiefer
    Hi All, today I've come across a rather weird issue. After adding code to validate a key (i added it below), the Simulator refuses to let go of the old plist file. I deleted the simulator folder in the Application Support folder, then deleted the *build directory and restarted xcode & build & run my app...still the same issue. the old plist is still there and 100% identical. I then changed the identifier and the snippet's validation keys, the plist however stayed the same. basically, no matter what i do it won't go. the same thing happens on the iphone itself. I have checked through the code, i don't create the key anywhere, but it still returns YES for it at every restart. Here's the code I added: + (void)initialize{ ////////////////////////////SPECIFING THE PREDATA/////////////////// NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSDictionary *appDefaults = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:NO] forKey:@"protect"]; [defaults registerDefaults:appDefaults]; } if ([[NSUserDefaults standardUserDefaults] boolForKey:@"protect"] == NO) { [navigationController pushViewController:help animated:YES]; [help.navigationItem hidesBackButton]; } else { [window addSubview:passcode.view]; [self performSelector:@selector(responder) withObject:nil afterDelay:1]; } as a result, it will always go for the else option, which for some reason, doesn't get executed either. I assumed an error but the log is empty and there's no crash.

I'm not too advanced with Ruby on Rails, so this throws me a bit.
