• 2D Barcode Addendum

  - by Tim Dexter

  Having finally got my external drive back(long story) today from Oklahoma (thank you so much Sammy) Im back with a full compliment of Oracle and blogging tools at my disposal. I have missed JDeveloper this past week, which I have found, I immensely prefer over Eclipse (let the flaming commence :0) I use Zoundry Raven for writing articles and its not installed locally but on my external drove, so I have been soldiering on with the blog server's pain in the backside UI for writing. Now I have my favority editor back and things are calming down workwise, I will start to get the Excel template posts out. Today thou, a note about 2D barcode support or more specifically any barcode that needs some data manipulation before the barcode font is applied. I wrote about these fonts a long time back and laid out the java class you would need to write if you had an algorithm from the font manufacturer to use. I missed out a valuable point and James at Luminex fell into the trap. He was wanting to use the datamatrix font from IDAutomation but and had built the java class to be called from the RTF template but it was not encoding or at least did not appear to be. New debugging feature to the rescue. Kan over at the bipconsultng blog documented the feature a while back. Just adding <?xdo-debug-level:'STATEMENT'?> to my test template generated all the debug files in my c:\temp directory. No messing with files, just a simple command ... at last! Kan has documented the feature here. With the log in hand I spotted a java error stack referencing a missing code128a method, huh? Looking at James' class he had the following snippet: ENCODERS.put("code128a",mUtility.getClass().getMethod("code128a",clazz)); ENCODERS.put("code128b",mUtility.getClass().getMethod("code128b", clazz)); ENCODERS.put("code128c",mUtility.getClass().getMethod("code128c", clazz)); ENCODERS.put("pdf417",mUtility.getClass().getMethod("pdf417", clazz)); ENCODERS.put("datamatrix",mUtility.getClass().getMethod("datamatrix", clazz)); His class did not include the other code128 and pdf147 methods and BIP was expecting them. An easy fix, just comment them out, rebuild and deploy and the encoding started working. If you are hitting similar problems, check that class and ensure all of the referenced methods are available, if not, delete or get commenting. James now has purdy labels popping out that his hard ware can read, sweet!

• Using Dependency Walker

  - by Valter Minute

  Dependency Walker is a very useful tool that can be used to find dependencies of a Portable Executable module. The PE format is used also on Windows CE and this means that Dependency Walker can be used to analyze also Windows CE/Windows Embedded Compact module. On Win32 it can be used also to monitor modules loaded by an application during runtime, this feature is not supported on CE. You can download dependency walker for free here: http://dependencywalker.com/. To analyze the dependencies of a Windows CE/Windows Embedded Compact 7 module you can just open it using Dependency Walker. If you want to check if a specific module can run on a Windows CE/Windows Compact 7 OS Image you can copy the executable in the same directory that contains your OS binaries (FLATRELEASEDIR). In this way Dependency Walker will highlight missing dlls or missing entry points inside existing dlls. Let’s do a quick sample. You need to check if myapp.exe (an application from a third party) can run on an image generated with your Test01 OSDesign. Copy Myapp.exe to the flat release directory of your OS Design. Launch depends.exe and use the File\Open option of its main menu to open the application executable file you just copied. You may receive an error if some of the modules required by your applications are missing. Before you analyze the module dependencies is important to configure Dependency Walker to check DLL in the same folder where your application file is stored. This is needed because some Windows CE DLLs have the same name of Win32 system DLLs but different entry points. To configure the DLL search path select “Options\Configure Module Search Order…” from Depenency Walker main menu. Select “The application directory” from the “Current Search Order” list, select it, and move it to the top of the list using the “Move Up” button. The system will ask to refresh the window contents to reflect your configuration change, click on “Yes” to proceed. Now you can inspect myapp.exe dependencies. Some DLLs are missing (XAMLRUNTIME.DLL and TILEENGINE.DLL) and OLE32.DLL exists but does not export the “CoInitialize” entry point that is required by myapp.exe. The bad news is that MyApp.exe will not run on your OS Image, the good news is that now you know what’s missing and you can add the required modules to your OS Design and fix the problem!

• What I like about WIF&rsquo;s Claims-based Authorization

  - by Your DisplayName here!

  In “traditional” .NET with its IPrincipal interface and IsInRole method, developers were encouraged to write code like this: public void AddCustomer(Customer customer) {     if (Thread.CurrentPrincipal.IsInRole("Sales"))     {         // add customer     } } In code reviews I’ve seen tons of code like this. What I don’t like about this is, that two concerns in your application get tightly coupled: business and security logic. But what happens when the security requirements change – and they will (e.g. members of the sales role and some other people from different roles need to create customers)? Well – since your security logic is sprinkled across your project you need to change the security checks in all relevant places (and make sure you don’t forget one) and you need to re-test, re-stage and re-deploy the complete app. This is clearly not what we want. WIF’s claims-based authorization encourages developers to separate business code and authorization policy evaluation. This is a good thing. So the same security check with WIF’s out-of-the box APIs would look like this: public void AddCustomer(Customer customer) {     try     {         ClaimsPrincipalPermission.CheckAccess("Customer", "Add");           // add customer     }     catch (SecurityException ex)     {         // access denied     } } You notice the fundamental difference? The security check only describes what the code is doing (represented by a resource/action pair) – and does not state who is allowed to invoke the code. As I mentioned earlier – the who is most probably changing over time – the what most probably not. The call to ClaimsPrincipalPermission hands off to another class called the ClaimsAuthorizationManager. This class handles the evaluation of your security policy and is ideally in a separate assembly to allow updating the security logic independently from the application logic (and vice versa). The claims authorization manager features a method called CheckAccess that retrieves three values (wrapped inside an AuthorizationContext instance) – action (“add”), resource (“customer”) and the principal (including its claims) in question. CheckAccess then evaluates those three values and returns true/false. I really like the separation of concerns part here. Unfortunately there is not much support from Microsoft beyond that point. And without further tooling and abstractions the CheckAccess method quickly becomes *very* complex. But still I think that is the way to go. In the next post I will tell you what I don’t like about it (and how to fix it).

• User Group Meeting Summary - April 2010

  - by Michael Stephenson

  Thanks to everyone who could make it to what turned out to be an excellent SBUG event.  First some thanks to:  Speakers: Anthony Ross and Elton Stoneman Host: The various people at Hitachi who helped to organise and arrange the venue.   Session 1 - Getting up and running with Windows Mobile and the Windows Azure Service Bus In this session Anthony discussed some considerations for using Windows Mobile and the Windows Azure Service Bus from a real-world project which Hitachi have been working on with EasyJet.  Anthony also walked through a simplified demo of the concepts which applied on the project.   In addition to the slides and demo it was also very interesting to discuss with the guys involved on this project to hear about their real experiences developing with the Azure Service Bus and some of the limitations they have had to work around in Windows Mobiles ability to interact with the service bus.   On the back of this session we will look to do some further activities around this topic and the guys offered to share their wish list of features for both Windows Mobile and Windows Azure which we will look to share for user group discussion.   Another interesting point was the cost aspects of using the ISB which were very low.   Session 2 - The Enterprise Cache In the second session Elton used a few slides which are based around one of his customer scenario's where they are looking into the concept of an Enterprise Cache within the organisation.  Elton discusses this concept and also a codeplex project he is putting together which allows you to take advantage of a cache with various providers such as Memcached, AppFabric Caching and Ncache.   Following the presentation it was interesting to hear peoples thoughts on various aspects such as the enterprise cache versus an out of process application cache.  Also there was interesting discussion around how people would like to search the cache in the future.   We will again look to put together some follow-up activity on this   Meeting Summary Following the meeting all slide decks are saved in the skydrive location where we keep content from all meetings: http://cid-40015ea59a1307c8.skydrive.live.com/browse.aspx/.Public/SBUG/SBUG%20Meetings/2010%20April   Remember that the details of all previous events are on the following page. http://uksoabpm.org/Events.aspx   Competition We had three copies of the Windows Identity Foundation Patterns and Practices book that were raffles on the night, it would be great to hear any feedback on the book from those who won it.   Recording The user group meeting was recorded and we will look to make this available online sometime soon.   UG Business The following things were discussed as general UG topics:   We will change the name of the user group to the UK Connected Systems User Group to we are more inline with other user groups who cover similar topics and we believe this will help us to attract more members.  The content or focus of the user group is not expected to change.   The next meeting is 26th May and can be registered at the following link: http://sbugmay2010.eventbrite.com/

• SQL SERVER – Various Leap Year Logics

  - by pinaldave

  Earlier I wrote one article on Leap Year and created one video about Leap Year. My point of view was to demonstrate how we can use SQL Server 2012 features to identify Leap year. How ever during the conversation I had some really good conversation. Here are updates for those who have missed reading the excellent comments on the blog. Incorrect Logic There are so many people still think Leap Year is the event which is consistently happening at every four year and the way to find it is divide the year with 4 and if the remainder is 0. That year is leap year. Well, it is not correct. Comment by David Bridge Check out this excerpt from wikipedia page http://en.wikipedia.org/wiki/Leap_year “most years that are evenly divisible by 4 are leap years…” “…Some exceptions to this rule are required since the duration of a solar year is slightly less than 365.25 days. Years that are evenly divisible by 100 are not leap years, unless they are also evenly divisible by 400, in which case they are leap years. For example, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not. Similarly, 2100, 2200, 2300, 2500, 2600, 2700, 2900 and 3000 will not be leap years, but 2400 and 2800 will be.” If you use logic of divide by 4 and remainder is 0 to find leap year, you will may end up with inaccurate result. The correct way to identify the year is to figure out the days of February and if the count is 29, the year is for sure leap year. Valid Alternate Solutions Comment by sainswor99insworth IIF((@Year%4=0 AND @Year%100 != 0) OR @Year%400=0, 1,0) Comment by Madhivanan Madhivanan has written a blog post about an year ago where he listed multiple ways to find leap year. Comment by Jayan DECLARE @year INT SET @year = 2012 IF (((@year % 4 = 0) AND (@year % 100 != 0)) OR (@year % 400 = 0)) PRINT ’1' ELSE print ’0' Comment by David DECLARE @Year INT = 2012 SELECT ISDATE('2/29/' + CAST(@Year AS CHAR(4))) Comment by David Bridge Incidentally – Another approach would be to take one day off March 1st and see if it is 29.

• NoSQL is not about object databases

  - by Bertrand Le Roy

  NoSQL as a movement is an interesting beast. I kinda like that it’s negatively defined (I happen to belong myself to at least one other such a-community). It’s not in its roots about proposing one specific new silver bullet to kill an old problem. it’s about challenging the consensus. Actually, blindly and systematically replacing relational databases with object databases would just replace one set of issues with another. No, the point is to recognize that relational databases are not a universal answer -although they have been used as one for so long- and recognize instead that there’s a whole spectrum of data storage solutions out there. Why is it so hard to recognize, by the way? You are already using some of those other data storage solutions every day. Let me cite a few: The file system Active Directory XML / JSON documents The Web e-mail Logs Excel files EXIF blobs in your photos Relational databases And yes, object databases It’s just a fact of modern life. Notice by the way that most of the data that you use every day is unstructured and thus mostly unsuitable for relational storage. It really is more a matter of recognizing it: you are already doing NoSQL. So what happens when for any reason you need to simultaneously query two or more of these heterogeneous data stores? Well, you build an index of sorts combining them, and that’s what you query instead. Of course, there’s not much distance to travel from that to realizing that querying is better done when completely separated from storage. So why am I writing about this today? Well, that’s something I’ve been giving lots of thought, on and off, over the last ten years. When I built my first CMS all that time ago, one of the main problems my customers were facing was to manage and make sense of the mountain of unstructured data that was constituting most of their business. The central entity of that system was the file system because we were dealing with lots of Word documents, PDFs, OCR’d articles, photos and static web pages. We could have stored all that in SQL Server. It would have worked. Ew. I’m so glad we didn’t. Today, I’m working on Orchard (another CMS ;). It’s a pretty young project but already one of the questions we get the most is how to integrate existing data. One of the ideas I’ll be trying hard to sell to the rest of the team in the next few months is to completely split the querying from the storage. Not only does this provide great opportunities for performance optimizations, it gives you homogeneous access to heterogeneous and existing data sources. For free.

• SQL SERVER – A Puzzle – Fun with NULL – Fix Error 8117

  - by pinaldave

  During my 8 years of career, I have been involved in many interviews. Quite often, I act as the  interview. If I am the interviewer, I ask many questions – from easy questions to difficult ones. When I am the interviewee, I frequently get an opportunity to ask the interviewer some questions back. Regardless of the my capacity in attending the interview, I always make it a point to ask the interviewer at least one question. What is NULL? It’s always fun to ask this question during interviews, because in every interview, I get a different answer. NULL is often confused with false, absence of value or infinite value. Honestly, NULL is a very interesting subject as it bases its behavior in server settings. There are a few properties of NULL that are universal, but the knowledge about these properties is not known in a universal sense. Let us run this simple puzzle. Run the following T-SQL script: SELECT SUM(data) FROM (SELECT NULL AS data) t It will return the following error: Msg 8117, Level 16, State 1, Line 1 Operand data type NULL is invalid for sum operator. Now the error makes it very clear that NULL is invalid for sum Operator. Frequently enough, I have showed this simple query to many folks whom I came across. I asked them if they could modify the subquery and return the result as NULL. Here is what I expected: Even though this is a very simple looking query, so far I’ve got the correct answer from only 10% of the people to whom I have asked this question. It was common for me to receive this kind of answer – convert the NULL to some data type. However, doing so usually returns the value as 0 or the integer they passed. SELECT SUM(data) FROM (SELECT ISNULL(NULL,0) AS data) t I usually see many people modifying the outer query to get desired NULL result, but that is not allowed in this simple puzzle. This small puzzle made me wonder how many people have a clear understanding about NULL. Well, here is the answer to my simple puzzle. Just CAST NULL AS INT and it will return the final result as NULL: SELECT SUM(data) FROM (SELECT CAST(NULL AS INT) AS data) t Now that you know the answer, don’t you think it was very simple indeed? This blog post is especially dedicated to my friend Madhivanan who has written an excellent blog post about NULL. I am confident that after reading the blog post from Madhivanan, you will have no confusion regarding NULL in the future. Read: NULL, NULL, NULL and nothing but NULL.

• Data validation best practices: how can I better construct user feedback?

  - by Cory Larson

  Data validation, whether it be domain object, form, or any other type of input validation, could theoretically be part of any development effort, no matter its size or complexity. I sometimes find myself writing informational or error messages that might seem harsh or demanding to unsuspecting users, and frankly I feel like there must be a better way to describe the validation problem to the user. I know that this topic is subjective and argumentative. I've migrated this question from StackOverflow where I originally asked it with little response. Basically, I'm looking for good resources on data validation and user feedback that results from it at a theoretical level. Topics and questions I'm interested in are: Content Should I be describing what the user did correctly or incorrectly, or simply what was expected? How much detail can the user read before they get annoyed? (e.g. Is "Username cannot exceed 20 characters." enough, or should it be described more fully, such as "The username cannot be empty, and must be at least 6 characters but cannot exceed 30 characters."?) Grammar How do I decide between phrases like "must not," "may not," or "cannot"? Delivery This can depend on the project, but how should the information be delivered to the user? Should it be obtrusive (e.g. JavaScript alerts) or friendly? Should they be displayed prominently? Immediately (i.e. without confirmation steps, etc.)? Logging Do you bother logging validation errors? Internationalization Some cultures prefer or better understand directness over subtlety and vice-versa (e.g. "Don't do that!" vs. "Please check what you've done."). How do I cater to the majority of users? I may edit this list as I think more about the topic, but I'm genuinely interested in proper user feedback techniques. I'm looking for things like research results, poll results, etc. I've developed and refined my own techniques over the years that users seem to be okay with, but I work in an environment where the users prefer to adapt to what you give them over speaking up about things they don't like. I'm interested in hearing your experiences in addition to any resources to which you may be able to point me.

• Playing NSF music in FMOD.net

  - by Tesserex

  So, as the title says, I want to be able to play NSF files using FMOD, because my project already uses FMOD and I'd rather not replace it. This will involve figuring out how existing players and emulators work and porting it. I haven't yet found an existing player that uses FMOD. My starting point is the MyNes source from http://sourceforge.net/projects/mynes/. There are two big steps between here and what I'm looking for. MyNes plays from a ROM, not NSF. So, I have to rip out the APU and get it to play NSF files. The MyNes APU uses SlimDX, so I have to convert that to FMOD.NET. I am really stuck about how to go about either of these, because I'm not that familiar with audio formats and it's hard finding resources online. So here are a few questions: From what I can tell from the NSF spec at http://kevtris.org/nes/nsfspec.txt, it's just contains the relevant memory section of the ROM, plus the header. If anyone can verify or correct this that would be great. The emulator APU uses data from the rest of the emulator to play, including things like cycle counts. I'm not sure what replaces this in a standalone player. Can't I just load all the music data at once into a stream and play it? Joining #1 and #2, does the header data from the NSF substitute for some of the ROM data in the emulator code? Using FMOD, will I be following the usercreatedsound example for loading a stream? And does this format count as PCM? Specifically MyNes says PCM8. Any tips on loading / playing the stream in FMOD are appreciated. As an aside, I don't really understand the loading / playing sections of the spec I linked at all. It seems to apply to 6502 systems / emulators only and not to my situation. I know it's a long shot for anyone here to have enough experience in this area to help, but anything you can provide is definitely appreciated. A link to an existing .NET library that does this would be even better, but I don't believe one exists.

• ASP.NET Localization: Enabling resource expressions with an external resource assembly

  - by Brian Schroer

  I have several related projects that need the same localized text, so my global resources files are in a shared assembly that’s referenced by each of those projects. It took an embarrassingly long time to figure out how to have my .resx files generate “public” properties instead of “internal” so I could have a shared resources assembly (apparently it was pretty tricky pre-VS2008, and my “googling” bogged me down some out-of-date instructions). It’s easy though – Just change the “Custom Tool” to “PublicResXFileCodeGenerator”:    …which can be done via the “Access Modifier” dropdown of the resource file designer window:   A reference to my shared resources DLL gives me the ability to use the resources in code, but by default, the ASP.NET resource expression syntax: <asp:Button ID="BeerButton" runat="server" Text="<%$ Resources:MyResources, Beer %>" />   …assumes that your resources are in your web site project.   To make resource expressions work with my shared resources assembly, I added two classes to the resources assembly: 1) a custom IResourceProvider implementation:   1: using System; 2: using System.Web.Compilation; 3: using System.Globalization; 4:   5: namespace DuffBeer 6: { 7: public class CustomResourceProvider : IResourceProvider 8: { 9: public object GetObject(string resourceKey, CultureInfo culture) 10: { 11: return MyResources.ResourceManager.GetObject(resourceKey, culture); 12: } 13:   14: public System.Resources.IResourceReader ResourceReader 15: { 16: get { throw new NotSupportedException(); } 17: } 18: } 19: }   2) and a custom factory class inheriting from the ResourceProviderFactory base class:   1: using System; 2: using System.Web.Compilation; 3:   4: namespace DuffBeer 5: { 6: public class CustomResourceProviderFactory : ResourceProviderFactory 7: { 8: public override IResourceProvider CreateGlobalResourceProvider(string classKey) 9: { 10: return new CustomResourceProvider(); 11: } 12:   13: public override IResourceProvider CreateLocalResourceProvider(string virtualPath) 14: { 15: throw new NotSupportedException(String.Format( 16: "{0} does not support local resources.", 17: this.GetType().Name)); 18: } 19: } 20: }   In the “system.web / globalization” section of my web.config file, I point the “resourceProviderFactoryType" property to my custom factory:   <system.web> <globalization culture="auto:en-US" uiCulture="auto:en-US" resourceProviderFactoryType="DuffBeer.CustomResourceProviderFactory, DuffBeer" />   This simple approach met my needs for these projects , but if you want to create reusable resource provider and factory classes that allow you to specify the assembly in the resource expression, the instructions are here.

• TSAM 11gR1

  - by todd.little

  The Tuxedo System and Application Monitor (TSAM) 11gR1 release provides powerful new application monitoring capabilities, as well as significant improvements in ease of use. The first thing users will notice is the completely redesigned user interface in the TSAM console. Based on Oracle ADF, the console is much easier to navigate, provides a Web 2.0 style interface with dynamically updating panels, and a look and feel familiar to those that have used Oracle Enterprise Manager. Monitoring data can be viewed in both tabular and graphical form and exported to Excel for further analysis. A number of new metrics are collected and displayed in this release. Call path monitoring now displays CPU time, message size, total transport time, and client address giving even more end-to-end information about a specific Tuxedo request. As well the call path display has been completely revamped to make it much easier to see the branches of the call path. The call pattern display now provides statistics on successful vs failed calls, system and application failures, and end-to-end average elapsed time. Service monitoring now displays minimum and maximum message size, CPU usage, and client address. System server monitoring now includes monitoring the SALT gateway servers to provide detailed performance metrics about those servers. Perhaps the most significant new feature is the consolidation of alert definitions and policy management. In previous versions of TSAM, some alerts were defined and checked on the monitored systems while others were defined and checked in the console. Policy management could be performed on both the monitored node via environment variable or command, as well as from the console. Now all alert definitions and policy definitions are only made using the console. For alerts this means that regardless of where the alert is evaluated it is defined in one and only one place. Thus the plug-in alert mechanism of previous releases can now be managed using the TSAM console, making SLA alert definition much easier and cleaner. Finally there is support in TSAM for monitoring rehosted mainframe applications. The newly announced Oracle Tuxedo Application Runtime for CICS and Batch can be monitored in the TSAM console using traditional mainframe views of the application such as regions. Look for a future blog entry with more details on this as well as some entries providing a glimpse of the console. TSAM gives users a single point for monitoring the performance of all of their Tuxedo applications.

• How Microsoft listens

  - by Stacy Vicknair

  This being my freshman year as an MVP, I had a realization that I perhaps should be embarrassed hasn’t happened sooner. The realization comes much like the iconic M&Ms commercial where the M&Ms run into Santa and exclaim, “He does exist!” My personal realization arguably has a greater implication: Microsoft does listen. This is the most important lesson that I received this year attending the MVP Summit. My hope is that I can convince you that we are empowered to make a difference. Instead of using “Man I hate how this works / doesn’t work!” as cooler conversation, we can use it as true interaction with Microsoft. We as customers to Microsoft need to stop asking the question “Will this work for me?” and instead ask “How can this work for me?” There are three quick resources that the average developer has access to today that they can use to be heard by the product teams, and by no means should you think twice if you have a concern that you’d like a real response on. MVPs MVPs are members of your community who have a deep relationship with Microsoft and will have connections to their associated product group. Don’t think of them as just a resource for answers, but also as your ambassador for getting your experiences heard. You can find your local MVPs by browsing the directory at: https://mvp.support.microsoft.com/communities/mvp.aspx Evangelists Evangelists are employees of Microsoft who work to foster and grow communities in their assigned region. They are first-class citizens of Microsoft and are often deeply involved with the product groups. As a result, they will be more than glad to direct your questions or concerns to those who can answer them most expertly. With that said, evangelists are also very busy people (who do amazing things for the community) and might not be able to get you that conversation as quickly as a local MVP. You can find your local evangelist at the following website: http://msdn.microsoft.com/en-us/bb905078.aspx Microsoft Connect This is one of the resources that I haven’t used enough, but it cannot be understated. Connect is the starting point of the social conversation that happens between Microsoft and the community daily. Connect acts as a portal where you can provide new feedback as well as comment and rate the feedback provided by others. Power is in numbers when it comes to Connect, so the exposure that your feedback can get not only lets you know that you aren’t the only one who wants change, but also lets Microsoft know the same. https://connect.microsoft.com   Technorati Tags: Microsoft,MVP,Feedback,Connect

• Cloud Computing : publication du volet 3 du Syntec Numérique

  - by Eric Bezille

  Une vision client/fournisseur réunie autour d'une ébauche de cadre contractuel Lors de la Cloud Computing World Expo qui se tenait au CNIT la semaine dernière, j'ai assisté à la présentation du nouveau volet du Syntec numérique sur le Cloud Computing et les "nouveaux modèles" induits : modèles économiques, contrats, relations clients-fournisseurs, organisation de la DSI. L'originalité de ce livre blanc vis à vis de ceux déjà existants dans le domaine est de s'être attaché à regrouper l'ensemble des acteurs clients (au travers du CRIP) et fournisseurs, autour d'un cadre de formalisation contractuel, en s'appuyant sur le modèle e-SCM. Accélération du passage en fournisseur de Services et fin d'une IT en silos ? Si le Cloud Computing permet d'accélérer le passage de l'IT en fournisseur de services (dans la suite d'ITIL v3), il met également en exergue le challenge pour les DSI d'un modèle en rupture nécessitant des compétences transverses permettant de garantir les qualités attendues d'un service de Cloud Computing : déploiement en mode "self-service" à la demande, accès standardisé au travers du réseau,  gestion de groupes de ressources partagées,  service "élastique" : que l'on peut faire croitre ou diminuer rapidement en fonction de la demande mesurable On comprendra bien ici, que le Cloud Computing va bien au delà de la simple virtualisation de serveurs. Comme le décrit fort justement Constantin Gonzales dans son blog ("Three Enterprise Principles for Building Clouds"), l'important réside dans le respect du standard de l'interface d'accès au service. Ensuite, la façon dont il est réalisé (dans le nuage), est de la charge et de la responsabilité du fournisseur. A lui d'optimiser au mieux pour être compétitif, tout en garantissant les niveaux de services attendus. Pour le fournisseur de service, bien entendu, il faut maîtriser cette implémentation qui repose essentiellement sur l'intégration et l'automatisation des couches et composants nécessaires... dans la durée... avec la prise en charge des évolutions de chacun des éléments. Pour le client, il faut toujours s'assurer de la réversibilité de la solution au travers du respect des standards... Point également abordé dans le livre blanc du Syntec, qui rappelle les points d'attention et fait un état des lieux de l'avancement des standards autour du Cloud Computing. En vous souhaitant une bonne lecture...

• Is your test method self-validating ?

  - by mehfuzh

  Writing state of art unit tests that can validate your every part of the framework is challenging and interesting at the same time, its like becoming a samurai. One of the key concept in this is to keep our test synced all the time as underlying code changes and thus breaking them to the furthest unit as possible.  This also means, we should avoid  multiple conditions embedded in a single test. Let’s consider the following example of transfer funds. [Fact] public void ShouldAssertTranserFunds() {     var currencyService = Mock.Create<ICurrencyService>();     //// current rate     Mock.Arrange(() => currencyService.GetConversionRate("AUS", "CAD")).Returns(0.88f);       Account to = new Account { Currency = "AUS", Balance = 120 };     Account from = new Account { Currency = "CAD" };       AccountService accService = new AccountService(currencyService);       Assert.Throws<InvalidOperationException>(() => accService.TranferFunds(to, from, 200f));       accService.TranferFunds(to, from, 100f);       Assert.Equal(from.Balance, 88);     Assert.Equal(20, to.Balance); } At first look,  it seems ok but as you look more closely , it is actually doing two tasks in one test. At line# 10 it is trying to validate the exception for invalid fund transfer and finally it is asserting if the currency conversion is successfully made. Here, the name of the test itself is pretty vague. The first rule for writing unit test should always reflect to inner working of the target code, where just by looking at their names it is self explanatory. Having a obscure name for a test method not only increase the chances of cluttering the test code, but it also gives the opportunity to add multiple paths into it and eventually makes things messy as possible. I would rater have two test methods that explicitly describes its intent and are more self-validating. ShouldThrowExceptionForInvalidTransferOperation ShouldAssertTransferForExpectedConversionRate Having, this type of breakdown also helps us pin-point reported bugs easily rather wasting any time on debugging for something more general and can minimize confusion among team members. Finally, we should always make our test F.I.R.S.T ( Fast.Independent.Repeatable.Self-validating.Timely) [ Bob martin – Clean Code]. Only this will be enough to ensure, our test is as simple and clean as possible.   Hope that helps

• Enable Thumbnail Previews for Firefox in Windows 7 Taskbar

  - by Asian Angel

  Are you tired of waiting for the official activation of Taskbar Thumbnail Previews in Firefox? See how easy it is to enable them now with a simple about:config hack. Note: We have briefly covered this before but present it here in a more detailed format. Before For our example we opened all of the websites in the HTG Network in tabs… When hovering over the Firefox Icon in the Taskbar, you only see the one thumbnail. There are two things in particular to notice here: 1.) The Tab Bar for Firefox is displayed with all four tabs visible in the Thumbnail Preview  2.) The “Taskbar Icon” itself is displaying as singular with no “fanned edge” on the right side. Hack the About:Config Settings To get the Thumbnail Previews working you will need to make a modification in the about:config settings. Type about:config in the Address Bar and press Enter. Unless you have previously disabled the warning you will see this message after pressing Enter. Click on the I promise! Button to finish entering the settings. In the Filter Address Bar either type or copy and paste the following about:config entry: browser.taskbar.previews.enable After you enter that in, you should see the entry listing as shown here. At this point there are two methods that you can choose to alter the entry. The first method is to right click on the entry and select Toggle and the second method is to double click on the entry. Both work equally well…choose the method that you like best. Once the about:config entry has been changed, you will need to restart Firefox for it to take effect. After restarting Firefox on our system the Thumbnail Previews were definitely looking very nice. Notice that the Tab Bar is no longer displayed in the Thumbnail Previews. The Taskbar Icon also had a “fanned edge” indicating that multiple tabs were open. Conclusion If you are tired of waiting for Mozilla to officially activate Taskbar Thumbnail Previews in Firefox, then you can go ahead and start enjoying them now.

• SSDT - What's in a name?

  - by jamiet

  SQL Server Data Tools (SSDT) recently got released as part of SQL Server 2012 and depending on who you believe it can be described as either: a suite of tools for building SQL Server database solutions or a suite of tools for building SQL Server database, Integration Services, Analysis Services & Reporting Services solutions Certainly the SQL Server 2012 installer seems to think it is the latter because it describes SQL Server Data Tools as "the SQL server development environment, including the tool formerly named Business Intelligence Development Studio. Also installs the business intelligence tools and references to the web installers for database development tools" as you can see here: Strange then that, seemingly, there is no consensus within Microsoft about what SSDT actually is. On yesterday's blog post First Release of SSDT Power Tools reader Simon Lampen asked the quite legitimate question:I understand (rightly or wrongly) that SSDT is the replacement for BIDS for SQL 2012 and have just installed this. If this is the case can you please point me to how I can edit rdl and rdlc files from within Visual Studio 2010 and import MS Access reports.To which came the following reply:SSDT doesn't include any BIDs (sic) components. Following up with the appropriate team (Analysis Services, Reporting Services, Integration Services) via their forum or msdn page would be the best way to answer you questions about these kinds of services. That's from a Microsoft employee by the way. Simon is even more confused by this and replies with:I have done some more digging and am more confused than ever. This documentation (and many others) : msdn.microsoft.com/.../ms156280.aspx expressly states that SSDT is where report editing tools are to be foundAnd on it goes....You can see where Simon's confusion stems from. He has official documentation stating that SSDT includes all the stuff for building SSIS/SSAS/SSRS solutions (this is confirmed in the installer, remember) yet someone from Microsoft tells him "SSDT doesn't include any BIDs components".I have been close to this for a long time (all the way through the CTPs) so I can kind of understand where the confusion stems from. To my understanding SSDT was originally the name of the database dev stuff but eventually that got expanded to include all of the dev tools - I guess not everyone in Microsoft got the memo.Does this sound familiar? Have we not been down this road before? The database dev tools have had upteen names over the years (do any of datadude, TSData, VSTS for DB Pros, DBPro, VS2010 Database Projects sound familiar) and I was hoping that the SSDT moniker would put all confusion to bed - evidently its as complicated now as it has ever been.Forgive me for whinging but putting meaningful, descriptive, accurate, well-defined and easily-communicated names onto a product doesn't seem like a difficult thing to do. I guess I'm mistaken!Onwards and upwards...@Jamiet

• Development processes, the use of version control, and unit-testing

  - by ct01

  Preface I've worked at quite a few "flat" organizations in my time. Most of the version control policy/process has been "only commit after it's been tested". We were constantly committing at each place to "trunk" (cvs/svn). The same was true with unit-testing - it's always been a "we need to do this" mentality but it never really materializes in a substantive form b/c there is no institutional knowledge base to do it - no mentorship. Version Control The emphasis for version control management at one place was a very strict protocol for commit messages (format & content). The other places let employees just do "whatever". The branching, tagging, committing, rolling back, and merging aspect of things was always ill defined and almost never used. This sort of seems to leave the version control system in the position of being a fancy file-storage mechanism with a meta-data component that never really gets accessed/utilized. (The same was true for unit testing and committing code to the source tree) Unit tests It seems there's a prevailing "we must/should do this" mentality in most places I've worked. As a policy or standard operating procedure it never gets implemented because there seems to be a very ill-defined understanding about what that means, what is going to be tested, and how to do it. Summary It seems most places I've been to think version control and unit testing is "important" b/c the trendy trade journals say it is but, if there's very little mentorship to use these tools or any real business policies, then the full power of version control/unit testing is never really expressed. So grunts, like myself, never really have a complete understanding of the point beyond that "it's a good thing" and "we should do it". Question I was wondering if there are blogs, books, white-papers, or online journals about what one could call the business process or "standard operating procedures" or uses cases for version control and unit testing? I want to know more than the trade journals tell me and get serious about doing these things. PS: @Henrik Hansen had a great comment about the lack of definition for the question. I'm not interested in a specific unit-testing/versioning product or methodology (like, XP) - my interest is more about work-flow at the individual team/developer level than evangelism. This is more-or-less a by product of the management situation I've operated under more than a lack of reading software engineering books or magazines about development processes. A lot of what I've seen/read is more marketing oriented material than any specifically enumerated description of "well, this is how our shop operates".

• How to share two keyboard on the same laptop, french iso layout and usa ansi layout keyboard with usb?

  - by reyman64

  I recently buy a "noppoo choc mini" with this specific ANSI US-INTERNATIONAL pc84 layout. This specific keyboard have only 84 key , a 60% (compact tenkeyless) reduced layout My problem is simple, there is no keyboard layout into Ubuntu 12.04 which correspond to this usa normal ansi layout ... so it's the same problem with reduced version and only 84 key .. I search a template of normal ANSI US-INTERNATIONAL for xmodmap/xkb, and after i can try to manually map the other key. I search on google, and i don't find any other user which have same problem, so it's seem i have not the good keywoard to search this information.. Edit 1 : Here you can see there is probably a bug in ubuntu, because the layout for USA with dead key is not correct ! I have this : http://minus.com/lEdKMrsNAwkVA And other users have this for the same layout : http://i.stack.imgur.com/p52XG.png EDIT 2 It seems after a "sudo dpkg-reconfigure keyboard-configuration" : french standard keyboard pc105 + precision M65 keyboard from dell laptop Now i can see the good us layout in parameters, but i cannot have the iso layout for french usage... EDIT 3 Ok, after reboot i understand the probleme, i explain. I have one laptop with integrated french keyboard, and i want to use my usb keyboard which use a usa ANSI layout. It seem it's impossible in ubuntu and "dpkg-reconfigure keyboard-configuration" to share two different physical layout (ANSI and EU ISO) on the same computer ... EDIT4 Ok, it seems i can switch the physical layout (ISO <- ANSI) with this command in terminal : setxkbmap -layout us setxkbmap -layout us -variant alt-intl an setxkbmap -layout fr It's very complicated qnd it seem ubuntu 12.04 have big problem with keyboard manager ... because all works great with these two commands, without ANY change into the system parameters keyboard !!! Second bug ? The image of the layout for fr is buggy, the layout is not ISO, but i can press on the letter "< " at the left of right shift without any problem ! You can see the image here (french alternative with ANSI layout ? it's crazy ?) : http: //minus.com/lXsDJwoeyWAfF Can you help me on this point ? I'm lost with xkb, and manual mapping is very complicated ... Thanks a lot, SR

• How do I (tactfully) tell my project manager or lead developer that the project's codebase needs serious work?

  - by Adam Maras

  I just joined a (relatively) small development team that's been working on a project for several months, if not a year. As with most developer joining a project, I spent my first couple of days reviewing the project's codebase. The project (a medium- to large-sized ASP.NET WebForms internal line of business application) is, for lack of a more descriptive term, a disaster. There are three immediately noticeable problems with the coding standards: The standard is very loose. It describes more of what not to do (don't use Hungarian notation, etc..) than what to do. The standard isn't always followed. There are inconsistencies with the code formatting everywhere. The standard doesn't follow Microsoft's style guidelines. In my opinion, there's no value in deviating from the guidelines that were set forth by the developer of the framework and the largest contributor to the language specification. As for point 3, perhaps it bothers me more because I've taken the time to get my MCPD with a focus on web applications (specifically, ASP.NET). I'm also the only Microsoft Certified Professional on the team. Because of what I learned in all of my schooling, self-teaching, and on-the-job learning (including my preparation for the certification exams) I've also spotted several instances in the project's code where things are simply not done in the best way. I've only been on this team for a week, but I see so many issues with their codebase that I imagine I'll be spending more time fighting with what's already written to do things in "their way" than I would if I were working on a project that, for example, followed more widely accepted coding standards, architecture patterns, and best practices. This brings me to my question: Should I (and if so, how do I) propose to my project manager and team lead that the project needs to be majorly renovated? I don't want to walk into their office, waving my MCTS and MCPD certificates around, saying that their project's codebase is crap. But I also don't want to have to stay silent and have to write kludgey code atop their kludgey code, because I actually want to write quality software and I want the end product to be stable and easily maintainable.

• Not Dead, Just Busy

  - by MOSSLover

  So I didn’t die in a freak smelting accident yet, but I have been dealing with a lot of different things.  I had to take a bit of a break to deal with the cat death issue.  I am not fully recovered, because well it just happened a few months ago.  It kind of sucked.  Plus the apartment feels a lot bigger. Then you have the whole New York Comic Con thing where I had to plan some cosplay costumes.  I have been trying to find time to hang out with friends and have a social life.  That plus I built an entire presentation for iOS development for New York Code Camp.  I am also planning a couple MS Community dinners (namely one a week from Tuesday) plus a give camp.  I am also planning a vacation around SPS UK plus I will be at SPC.  Life is just incredibly hectic and when you factor in dating to the mix it’s gotten insane to the point where some day I just have to go dark.  Hence the lack of blogging.  I am just trying to keep up with everything and everyone without losing myself. If you guys will be at SPC or SPS UK I will be at both places this year.  Stop by the Planet Technologies booth and see me or I’ll be around somewhere.  I am really sorry if I don’t remember you from an event or if you are someone following me on twitter.  I am trying to get better at the mnemonic memory devices, but I think things broke down around the 47th event I attended or spoke at or something to that nature.  If anyone wants to talk to Cathy, Lori, or I about Women in SharePoint definitely find us at the event.  Anyway good night and good luck guys.  I promise to check back at least once before the year ends.  In the meantime twitter stalking is always possible.  Sometimes I even respond back.

• A New Home for E-Business Suite Customer Adoption Information

  - by linda.fishman.hoyle

  Phew! I made it! A new home with my name. Let's talk about E-Business Suite. So much is going on and more and more customers are upgrading and implementing the latest release. I think I will highlight in this blog entry the most recent press release we issued 2 weeks ago about our Applications Unlimited success but in the release, we name several customers who are live on E-Business Suite Release 12.1 and then have a fabulous quote from a customer who is doing great things with our product.   Here is a link to the press release To make it easy for you, I am pulling out just the E-Business Suite information Oracle E-Business Suite: Oracle® E-Business Suite Release 12.1 provides organizations of all sizes, across all industries and regions, with a global business foundation that helps them reduce costs and increase productivity through a portfolio of rapid value solutions, integrated business processes and industry-focused solutions. The latest version of the Oracle E-Business Suite was designed to help organizations make better decisions and be more competitive by providing a global or holistic view of their operations. Abu Dhabi Media Company, Agilysis, C3 Business Solutions, Chicago Public Schools, Datacard Group, Guidance Software, Leviton Manufacturing, McDonald's, MINOR International, Usana Health Sciences, Zamil Plastic Industries Ltd. and Zebra Technologies are just a few of the organizations that have deployed the latest release of the Oracle E-Business Suite to help them make better decisions and be more competitive, while lowering costs and increasing performance. Customer Speaks "Leviton Manufacturing makes a very diverse line of products including electrical devices and data center products that we sell globally. We upgraded to the latest version of the Oracle E-Business Suite Release 12.1 to support our service business with change management, purchasing, accounts payable, and our internal IT help desk," said Bob MacTaggart, CIO of Leviton Manufacturing. "We consolidated seven Web sites that we used to host individually onto iStore. In addition, we run a site, using the Oracle E-Business Suite configurator, pricing and quoting for our sales agents to do configuration work. This site can now generate a complete sales proposal using Oracle functionality; we actually generate CAD drawings - the actual drawings themselves - based on configuration results. It used to take six to eight weeks to generate these drawings and now it's all done online in an hour to two hours by our sales agents themselves, totally self-service. It does everything they need. From our point of view that is a major business success. Not only is it a very cool, innovative application, but it also puts us about two years ahead of our competition."

• Antenna Aligner Part 10: Updates and emails…

  - by Chris George

  Since my last post back in July, I’ve not done huge amounts of work on my app for two reasons. Firstly, no time! Secondly, I wanted to leave it out in the wild for a while and see what happened. Well, what happened?  over 1,300 users, that’s what’s happened!  This uptake is beyond my wildest expectations, and apart from a couple of issues that I’ll mention in a minute, most of the feedback has been very positive indeed! I’ve had several emails giving me feedback and reporting issues, all of which I have made a point of replying to immediately. This act alone has met with favourable replies! One of the main issues was with iPad. So it turns out that my app is only accurate in portrait mode. Turning it into landscape will offset the direction by +-90degrees! Whoops! I think I’ve fixed this by disabling the orientation switching, but I have not yet had an iPad to test this on. I had several emails from iPod Touch users claiming the app did not work for them. Specifically, the compass view did not work. On investigation, it turns out that the iPod Touch does not have the compass hardware required to do this. Unfortunately there is no way to exclude iPod Touch’s from the list of supported devices, so I’ve just had to make it very clear in the itunes description that the device is not fully supported.  You can still get the list of transmitters, but you then have to use a real compass to get the bearing. But that’s not the end of the world. Several customers have requested the aerial polarisation to be displayed in the app. I was already working on this, and the data was already there, it was just a case of displaying this in the UI. I have a solution now, and this will be in the next release. Of course, with the Digital switchover in full swing across the UK, there have been one set of data updates (in 1.0.3), and another is due shortly. This reflects the transmitters as they switch over the digital fully and their power output increased. So all in all I’m very pleased with the feedback I’ve had, and I’m looking to get the next release out there by early December (allowing for the 2-3 week Apple approval lag!)
