• Profit's COLLABORATE 10 Session Selections

  - by Aaron Lazenby

  COLLABORATE 2010 is a mere 11 days away (thanks for the reminder @ocp_advisor). Every year I publish my a list of the sessions I think reflect some of the more interesting people/trends in enterprise IT. I should be at all of these sessions, so drop by for a chat--I'll be the guy tapping out emails on my iPad... Monday, April 19 9:15 a.m. - Keynote: Transforming Customer Value, Delivering Highest Customer Service Location: Keynote Hall I never miss Charles Phillips when he speaks--it's one of the best opportunities to get an update on Oracle product developments and strategy. And there's certainly occasion for an update: this will be Phillips' first big presentation since the Oracle + Sun Strategy Update in late January. Phillips is appearing with Oracle Executive Vice President of Development Thomas Kurian which means there should be some excellent information about how customers are using Oracle's complete software and hardware stack to address enterprise IT challenges. The session should provide some excellent context for the rest of the week's session...don't miss it. 10:45 a.m. - Oracle Fusion Applications: Functional Overview Location: South Seas FI met Basheer Khan at COLLABORATE 08 in Denver and have followed his work ever since. He's a former member of the OAUG Board of Directors, an Oracle ACE, and a charismatic enterprise IT expert. Having worked with the Oracle Usability Advisory Board, Basheer should have some fascinating insights to share about the features and interface of Oracle's Fusine Applications. This session, along with Nadia Bendjedou's "10 Things You Can Do Today to Prepare for the Next Generation Applications" (on Tuesday, April 20 8:00 a.m. in room 3662) should give attendees the update they need about Oracle's next-generation applications.   1:15p.m. - E-Business Suite in the Amazon Cloud Location: South Seas HI did my first full-fledged cloud computing coverage at last year's COLLABORATE show (check out my interview with Oracle's Bill Hodak), where I first learned about Amazon's EC2 offering. I've since talked with several people who have provisioned server space on Amazon's cloud with great results. So I'm looking forward to watching the audience configure an instance of the Oracle E-Business Suite release 12 on the cloud while Chuck Edwards from Blue Gecko drives. This session should take some of the mist and vapor out of the cloud conversation.2:30 p.m. - "Zero Sign-on" to EBS - Enabling 96000 Users to Login to EBS Without User Maintenance Location: South Seas HI'll be sitting tight in South Seas H for the next session on Monday where Doug Pepka, a ten-year veteran of communications giant Comcast, will be walking attendees through a massive single sign-on (SSO) project across the enterprise. I'm working on a story about SSO for the August issue of Profit, so this session has real practical value to me. Plus the proliferation of user account logins--both personal and professional--makes this a critical usability/change management issue for IT leaders planning for successful long-term IT implementations.   Tuesday 8:00 am  - Information Architecture for Men in Kilts Location: SURF AGetting to a 8:00 a.m. presentation is a tall order in Las Vegas, but presenter Billy Cripe will make it worth your effort. Not only is the title of this session great, but the content should appeal to any IT strategist looking to push the limits of Web 2.0 technologies in the enterprise. Cripe is a product management director of Enterprise 2.0 and Enterprise Content Management at Oracle, author of Reshaping Your Business with Web 2.0, and a prolific blogger--he knows how information architecture is critical to and enterprise 2.0 implementation.    10:30a.m. - Oracle Virtualization: From Desktop to Data Center Location: REEF FData center virtualization is still one of the best ways to reduce the cost of running enterprise IT. With the addition of Sun products, Oracle has the industry's most comprehensive virtualization portfolio. I must admit, I'm no expert in this subject. So I'm looking forward to Monica Kumar's presentation so I can get up to speed.   Wednesday 8:00 a.m. - The Art of the Steal Location: Mandalay Bay Ballroom JMany will know Frank Abagnale from Steven Spielberg's 2002 film "Catch Me if You Can." The one-time con man and international fugitive who swindled $2.5 million in forged checks went on to help U.S. federal officials investigate fraud cases. Now the CEO of Abagnale and Associates, he has become an invaluable source to the business world on the subject of fraud and fraud protection. With identity theft and digital fraud still on the rise, this session should be an entertaining, and sobering, education on the threats facing businesses and customers around the world. A great way to start Wednesday.1:00 p.m. - Google Wave: Will it replace e-mail as we know it today? Location: SURF EBy many assessments (my own included), Google Wave is a bit of an open collaboration failure. It may seem like an odd reason for me to be excited about this session, but I'm looking forward to the chance to revisit the technology. Also, this is a great case study in connecting free, available Internet tools to existing enterprise computing environments--an issue that IT strategists must contend with as workers spreads out and choose their own productivity tools.

• Machine freezes when configuring dual display on Ubuntu 9.10 (karmic)

  - by sa125

  Hi - I'm trying to configure dual displays on an Ubuntu 9.10 machine. When I connect the 2 screens (1 VGA input, the other DVI), I see them in a mirrored display. I opened up Display Settings and unchecked the 'mirror screens' box, and when I clicked apply, the machine froze and I had to force restart it. This happened repeatedly for about 6 times until I gave up. How do I set it up to boot up normally with dual display working? thanks. edit: I thought it might be related to the virtual screen size, so I tried to edit /etc/X11/xorg.conf to add: SubSection "Display" Virtual 2560 1024 EndSubSection But that didn't do much. Each screen works fine on it's own, and together with mirrored display.

• ASP.NET Connections Spring 2012 Talks and Code

  - by Stephen.Walther

  Thank you everyone who attended my ASP.NET Connections talks last week in Las Vegas. I’ve attached the slides and code for the three talks that I delivered:   Using jQuery to interact with the Server through Ajax – In this talk, I discuss the different ways to communicate information between browser and server using Ajax. I explain the difference between the different types of Ajax calls that you can make with jQuery. I also discuss the differences between the JavaScriptSerializer, the DataContractJsonSerializer, and the JSON.NET serializer.   ASP.NET Validation In-Depth – In this talk, I distinguish between View Model Validation and Domain Model Validation. I demonstrate how you can use the validation attributes (including the new .NET 4.5 validation attributes), the jQuery Validation library, and the HTML5 input validation attributes to perform View Model Validation. I then demonstrate how you can use the IValidatableObject interface with the Entity Framework to perform Domain Model Validation.   Using the MVVM Pattern with JavaScript Views – In this talk, I discuss how you can create single page applications (SPA) by taking advantage of the open-source KnockoutJS library and the ASP.NET Web API.   Be warned that the sample code is contained in Visual Studio 11 Beta projects. If you don’t have this version of Visual Studio, then you will need to open the code samples in Notepad. Also, I apologize for getting the code for these talks posted so slowly. I’ve been down with a nasty case of the flu for the past week and haven’t been able to get to a computer.

• Attend my GTC sessions

  - by Daniel Moth

  The last GTC conference in the US was 2 years ago and I was there as an attendee. You may recall from that blog post that we were running UX studies at the time. It really feels great 2 years later, to be back at GTC presenting two sessions on C++ AMP, demonstrating our progress that includes input from those early studies. If you are attending GTC (in person or virtually later), be sure to watch my two-part session. Part 1 is S0242 on Wednesday 5pm and part 2 is S0244 on Thursday 10am. Here is the shared abstract for both parts: Harnessing GPU Compute with C++ AMP C++ AMP is an open specification for taking advantage of accelerators like the GPU. In this session we will explore the C++ AMP implementation in Microsoft Visual Studio 11 Beta. After a quick overview of the technology understanding its goals and its differentiation compared with other approaches, we will dive into the programming model and its modern C++ API. This is a code heavy, interactive, two-part session, where every part of the library will be explained. Demos will include showing off the richest parallel and GPU debugging story on the market, in the upcoming Visual Studio release. See you there! Comments about this post by Daniel Moth welcome at the original blog.

• Putty: Send EOF

  - by joshhendo

  Hi, I'm running Windows 7, and am connecting to a Linux server using Putty. For some programs I'm writing, I need to be able to pass EOF to the input. On Linux I'd normally type Ctrl-Z, but in Putty that seems to exit the program. Ctrl-D doesn't seem to work either. I have had a look at: http://the.earth.li/~sgtatham/putty/0.58/htmldoc/Chapter3.html#using-sysmenu , which suggests looking at http://the.earth.li/~sgtatham/putty/0.58/htmldoc/Chapter4.html#config-telnetkey , though it seems to be if I'm connecting to a Telnet server, which I'm not. Any suggestions on what I could do? Thanks.

• How to learn & introduce scrum in small startup?

  - by Jens Bannmann

  In a few months, a friend will establish his startup software company, and I will be the software architect with one additional developer. Though we have no real day-to-day experience with agile methods, I have read much "overview" type of material on them, and I firmly believe they are a good - if not the only - way to build software. So with this company, I want to go for iterative, agile development from day 1, preferably something light-weight. I was thinking of Scrum, but the question is: what is the best way for me and my colleagues to learn about it, to introduce it (which techniques when etc) and to evaluate whether we should keep it? Background which might be relevant: we're all experienced developers around the same age with similar professional mindset. We have worked together in the past and afterwards at several different companies, mostly with a Java/.NET focus. Some are a bit familiar with general ideas from the agile movement. In this startup, I have great power over tools, methods and process. The startup's product will be developed from scratch and could be classified as middleware. We have some "customer" contacts in the industry who could provide input as soon as we get to an alpha stage.

• security issue of Linux sudo command?

  - by George2

  Hello everyone, 1. I am using Red Hat Enterprise 5 Linux box. I find if a user is in /etc/sudoers file, then if the user run command with sudo, the user will run this command with root privilege (without knowing root password, the user runs sudo only need to input the user's own password in order to run a command with sudo). Is that correct understanding? 2. If yes, then is it a security hole? Since users other than root could run with root privilege? thanks in advance, George

• BizTalk: mapping with Xslt

  - by Leonid Ganeline

  BizTalk Map Editor (Mapper) is a good editor, especially in the last 2010 version of the BizTalk. But still sometimes it cannot do the tasks easily. It is time for the Xslt code, It is time to remember that the maps are executed by the Xslt engine.  Right-click the Mapper Grid (a field between the source and target schemas) and choose Properties /Custom XSLT Path.  Input here a name of the file with Xslt code. Only this code will be executed, forget the picture in the Mapper, all those links and functoids.  Let’s see the real-life example. There are two source Addresses. One is on the top level and the second is inside the Member_Address record with MaxOccurs=* . The target address is placed inside the Locator record with MaxOccurs=*. The requirement is to map all source address to the one target address structure. The source Xml document looks like: The result Xml should be like this: Try to do this mapping with the Mapper and you will spent good amount of time and the result map would be tricky. If we use the Xslt code, the mapping will be simple and unambiguous, like this: Simple, elegant.

• Architect Day Artifacts

  - by Bob Rhubart

  In the last eight days the Oracle Technology Network Architect Day tour has stopped in Dallas, Anaheim (Disneyland, to be precise) , and at Oracle HQ in Redwood Shores,  CA. I was on-scene for the Dallas event, where I pulled a TMZ-style ambush on Chris Benedict from the Oracle Enterprise Solutions Group to capture this short video.     The other presenters escaped. But the slide decks from several of the presentations are now available on Slideshare:  IT Optimization: Reduce Data Center Costs and Set the Foundation for Future Growth as presented by Alan Levine, Oracle Enterprise Architect Senior Director Implementing Applications with SOA and Application Integration Architecture as presented by Vish Gaitonde, Director, Ecosystem Strategy, Application Integration Architecture Application Grid: Platform for Virtualization and Consolidation of Your Java Applications as presented by Sam Shah, Director, SOA and Integration, Oracle Enterprise Solutions Group Infrastructure Consolidation and Virtualization as presented by Steve Bennett, also a Director with the Oracle Enterprise Solutions Group Security in a Cloudy Architecture as presented by Geri Born, Security Specialist with the Oracle Enterprise Solutions Group I'll post more Architect Day presentations as soon as I track them down. A special thank you to Oracle ACE Directors Jordan Braunstein, Billy Tong, and Kai Yu, who were on hand in Dallas, and to fellow ACE Directors Basheer Khan and Floyd Teter for their participation in the Anaheim event.  (Floyd and his iPad came through again, allowing me to record the Anaheim panel discussion via Skype while sitting in my home office in Cleveland.) That audio, as well as audio from the panel discussion and a roundtable from the Dallas event, will be available soon as ArchBeat podcast programs. If you attended one of these events, a big thanks. Your active participation, your questions and input, are what these events are all about.  As new cities are added to the tour, we expect more of the same from the OTN architect community.

• WSDL-world vs CLR-world – some differences

  - by nmarun

  A change in mindset is required when switching between a typical CLR application and a web service application. There are some things in a CLR environment that just don’t add-up in a WSDL arena (and vice-versa). I’m listing some of them here. When I say WSDL-world, I’m mostly talking with respect to a WCF Service and / or a Web Service. No (direct) Method Overloading: You definitely can have overloaded methods in a, say, Console application, but when it comes to a WCF / Web Services application, you need to adorn these overloaded methods with a special attribute so the service knows which specific method to invoke. When you’re working with WCF, use the Name property of the OperationContract attribute to provide unique names. 1: [OperationContract(Name = "AddInt")] 2: int Add(int arg1, int arg2); 3:  4: [OperationContract(Name = "AddDouble")] 5: double Add(double arg1, double arg2); By default, the proxy generates the code for this as: 1: [System.ServiceModel.OperationContractAttribute( 2: Action="http://tempuri.org/ILearnWcfService/AddInt", 3: ReplyAction="http://tempuri.org/ILearnWcfService/AddIntResponse")] 4: int AddInt(int arg1, int arg2); 5: 6: [System.ServiceModel.OperationContractAttribute( 7: Action="http://tempuri.org/ILearnWcfServiceExtend/AddDouble", 8: ReplyAction="http://tempuri.org/ILearnWcfServiceExtend/AddDoubleResponse")] 9: double AddDouble(double arg1, double arg2); With Web Services though the story is slightly different. Even after setting the MessageName property of the WebMethod attribute, the proxy does not change the name of the method, but only the underlying soap message changes. 1: [WebMethod] 2: public string HelloGalaxy() 3: { 4: return "Hello Milky Way!"; 5: } 6:  7: [WebMethod(MessageName = "HelloAnyGalaxy")] 8: public string HelloGalaxy(string galaxyName) 9: { 10: return string.Format("Hello {0}!", galaxyName); 11: } The one thing you need to remember is to set the WebServiceBinding accordingly. 1: [WebServiceBinding(ConformsTo = WsiProfiles.None)] The proxy is: 1: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/HelloGalaxy", 2: RequestNamespace="http://tempuri.org/", 3: ResponseNamespace="http://tempuri.org/", 4: Use=System.Web.Services.Description.SoapBindingUse.Literal, 5: ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] 6: public string HelloGalaxy() 7:  8: [System.Web.Services.WebMethodAttribute(MessageName="HelloGalaxy1")] 9: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/HelloAnyGalaxy", 10: RequestElementName="HelloAnyGalaxy", 11: RequestNamespace="http://tempuri.org/", 12: ResponseElementName="HelloAnyGalaxyResponse", 13: ResponseNamespace="http://tempuri.org/", 14: Use=System.Web.Services.Description.SoapBindingUse.Literal, 15: ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] 16: [return: System.Xml.Serialization.XmlElementAttribute("HelloAnyGalaxyResult")] 17: public string HelloGalaxy(string galaxyName) 18:  You see the calling method name is the same in the proxy, however the soap message that gets generated is different. Using interchangeable data types: See details on this here. Type visibility: In a CLR-based application, if you mark a field as private, well we all know, it’s ‘private’. Coming to a WSDL side of things, in a Web Service, private fields and web methods will not get generated in the proxy. In WCF however, all your operation contracts will be public as they get implemented from an interface. Even in case your ServiceContract interface is declared internal/private, you will see it as a public interface in the proxy. This is because type visibility is a CLR concept and has no bearing on WCF. Also if a private field has the [DataMember] attribute in a data contract, it will get emitted in the proxy class as a public property for the very same reason. 1: [DataContract] 2: public struct Person 3: { 4: [DataMember] 5: private int _x; 6:  7: [DataMember] 8: public int Id { get; set; } 9:  10: [DataMember] 11: public string FirstName { get; set; } 12:  13: [DataMember] 14: public string Header { get; set; } 15: } 16: } See the ‘_x’ field is a private member with the [DataMember] attribute, but the proxy class shows as below: 1: [System.Runtime.Serialization.DataMemberAttribute()] 2: public int _x { 3: get { 4: return this._xField; 5: } 6: set { 7: if ((this._xField.Equals(value) != true)) { 8: this._xField = value; 9: this.RaisePropertyChanged("_x"); 10: } 11: } 12: } Passing derived types to web methods / operation contracts: Once again, in a CLR application, I can have a derived class be passed as a parameter where a base class is expected. I have the following set up for my WCF service. 1: [DataContract] 2: public class Employee 3: { 4: [DataMember(Name = "Id")] 5: public int EmployeeId { get; set; } 6:  7: [DataMember(Name="FirstName")] 8: public string FName { get; set; } 9:  10: [DataMember] 11: public string Header { get; set; } 12: } 13:  14: [DataContract] 15: public class Manager : Employee 16: { 17: [DataMember] 18: private int _x; 19: } 20:  21: // service contract 22: [OperationContract] 23: Manager SaveManager(Employee employee); 24:  25: // in my calling code 26: Manager manager = new Manager {_x = 1, FirstName = "abc"}; 27: manager = LearnWcfServiceClient.SaveManager(manager); The above will throw an exception saying: In short, this is saying, that a Manager type was found where an Employee type was expected! Hierarchy flattening of interfaces in WCF: See details on this here. In CLR world, you’ll see the entire hierarchy as is. That’s another difference. Using ref parameters: * can use ref for parameters, but operation contract should not be one-way (gives an error when you do an update service reference)   => bad programming; create a return object that is composed of everything you need! This one kind of stumped me. Not sure why I tried this, but you can pass parameters prefixed with ref keyword* (* terms and conditions apply). The main issue is this, how would we know the changes that were made to a ‘ref’ input parameter are returned back from the service and updated to the local variable? Turns out both Web Services and WCF make this tracking happen by passing the input parameter in the response soap. This way when the deserializer does its magic, it maps all the elements of the response xml thereby updating our local variable. Here’s what I’m talking about. 1: [WebMethod(MessageName = "HelloAnyGalaxy")] 2: public string HelloGalaxy(ref string galaxyName) 3: { 4: string output = string.Format("Hello {0}", galaxyName); 5: if (galaxyName == "Andromeda") 6: { 7: galaxyName = string.Format("{0} (2.5 million light-years away)", galaxyName); 8: } 9: return output; 10: } This is how the request and response look like in soapUI. As I said above, the behavior is quite similar for WCF as well. But the catch comes when you have a one-way web methods / operation contracts. If you have an operation contract whose return type is void, is marked one-way and that has ref parameters then you’ll get an error message when you try to reference such a service. 1: [OperationContract(Name = "Sum", IsOneWay = true)] 2: void Sum(ref double arg1, ref double arg2); 3:  4: public void Sum(ref double arg1, ref double arg2) 5: { 6: arg1 += arg2; 7: } This is what I got when I did an update to my service reference: Makes sense, because a OneWay operation is… one-way – there’s no returning from this operation. You can also have a one-way web method: 1: [SoapDocumentMethod(OneWay = true)] 2: [WebMethod(MessageName = "HelloAnyGalaxy")] 3: public void HelloGalaxy(ref string galaxyName) This will throw an exception message similar to the one above when you try to update your web service reference. In the CLR space, there’s no such concept of a ‘one-way’ street! Yes, there’s void, but you very well can have ref parameters returned through such a method. Just a point here; although the ref/out concept sounds cool, it’s generally is a code-smell. The better approach is to always return an object that is composed of everything you need returned from a method. These are some of the differences that we need to bear when dealing with services that are different from our daily ‘CLR’ life.

• How to crash a program

  - by user2949019

  I have a program called BlueCoat Proxy installed on my school issued laptop that basically blocks every second website on the Internet, including stack exchange, YouTube and yahoo answers. I do not have administrator rights, nor can I delete anything in program files, I tried every possible method of obtaining admin rights. It is not accessible in task manager (it doesn't even appear there). I tried to close it with Windows command prompt through commands like 'taskkill' but it returns 'Access is Denied' (I'm only denied access with that program). Does anyone know a method of crashing a program with a batch file or VB program? I was thinking something like the ping command, though for a program. Maybe automating 1000 meaningless requests to the program? Your input on the subject matter is appreciated, however telling me that this is wrong or illegal is not.

• Can I get my video card to output a DVI and VGA signal at the same time?

  - by Roy Pardee

  Hey All, I've got: a lovely 24" monitor, w/both DVI and VGA inputs, a personal desktop w/a Radeon HD Pro 2400 video card (both DVI and VGA outputs) a work laptop w/both outputs, and a KVM switch that handles VGA only Right now I've got laptop connected to the monitor's VGA, and the desktop connected to the DVI. This works, but requires me to switch the KVM and monitor input sources separately, which annoys me (I switch back & forth a lot to make skype calls & manage my music). I'd like to feed both VGA and DVI signals out of my desktop so I can do quick things on my desktop & switch right back, but then when I'm done working, switch the monitor over to DVI to get the crisper picture. Alas, just attaching both VGA and DVI cables to my desktop's video card did not do the trick. Can this card be persuaded to output both signals at the same time? Many thanks! -Roy

• The Oracle Retail Week Awards - in review

  - by user801960

  The Oracle Retail Week Awards 2012 were another great success, building on the legacy of previous award ceremonies. Over 1,600 of the UK's top retailers gathered at the Grosvenor House Hotel and many of Europe's top retail leaders attended the prestigious Oracle Retail VIP Reception in the Grosvenor House Hotel's Red Bar. Over the years the Oracle Retail Week Awards have become a rallying point for the morale of the retail industry, and each nominated retailer served as a demonstration that the industry is fighting fit.

• Intermittent freeze of Windows 7 x64 on laptop

  - by georged

  I have Lenovo W500, 8GB RAM, 250GB Crucial SSD running Windows 7 x64 using boot-to-vhd. Lately I started to experience some random freezes for 5-30 seconds. And when I say "freeze" I mean it; it's like a time machine - no input taken, nothing is written anywhere, no log, no disk activity. And then suddenly machine would wake up and continue as if nothing happened. I do suspect that it's one of the drivers but I don't see any updates in the log lately except for .NET 4 framework and Adobe Reader. Out of new or updated software I can only recall Skype and IE9 but freezes started to occur definitely before IE install. Regular software includes but not limited to: Office 2010, VMWare Workstation, IE9, Chrome, Skype, Seesmic/TweeterDeck, Live Writer. How should I approach the "hunting season" to find our the culprit? Any tools or packages that could help me to identify the component, program, driver that causes the freeze? Cheers

• Apache Solr: What is a good strategy for creating a tag/attribute based search for an image.

  - by Development 4.0

  I recently read an article about YayMicro that descries how they used solr to search their photos. I would like doing something similar (but on a smaller scale). I have figured out how to have solr to search text files, but I would like to learn what the best way to associate images with semi structured/unstructured text. Do I create an xml file with an image link in it? I basically want to input a search string and have it return a grid of images. Yay Micro Article Link

• moving to a new dedicated server and need advice on the new setup

  - by Eric Martin

  I currently have a dedicated server that we have outgrown and we are moving to another server. Our current setup was a 8gb W2008R2 server running a W2008R2 IIS virtual machine using VMWare. We are moving to a 2 cpu 24 gb server with W2012 R2 on Hyper-V. On our virtual machine we are running iis 7.5 and sql server. Sql Server seems to want to eat up all the memory so I had to cap it at 2gb, which doesn't seem sufficient. My question is, when I move the virtual machine to the new server, should I create 2 virtual machines, one for sql server and one for IIS? Or should I leave them both on the same virtual machine? Or even, put the Sql Server on the dedicated server and run the IIS in the vm? I'd like some input on how this should be done, I've not got the experience needed to make the right call. Thanks!

• open mysql to any connection on ubuntu

  - by ThomasReggi

  I simply want to open up mysql to be accessible from any server ip. I have already commented out the bind-address in /etc/mysql/my.conf. I have already setup the user account within mysql. I have no clue whats stopping me from connecting. The more challenging I see this being the more I realize how much of a security risk it is, and I get that, I just want to be able to do it temporarily. I think that the iptables firewall is the last thing that is preventing me from achieving this, but sudo iptables -A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT is seemingly doing nothing.

• Remote Desktop Mobile mangles barcodes coming from scanner

  - by sfonck

  Hi, We have an application here using handhelds to scan barcodes. These handhelds are actually making a remote desktop session towards a server where the application runs. Works fine. Now we have bought some new Motorola MC55's running 'Windows Mobile 6.1 Classic', and when using the application over remote desktop: it mangles the characters of the barcodes.... I already tried following things: When scanning a barcode on the MC55 itself it is displayed correctly When scanning a barcode via the remote desktop into a notepad session it is incorrect. Played with all options of the 'Remote Desktop Mobile' - no result Disabled 'autocorrect' and 'suggest words when entering text' on the input settings - no result The strange things is: a barcode which consists of only numbers gets scanned correctly the mangled characters comes through in lower case For some codes \t is mangled in between (should normally be entered after the barcode) e.g.: 'PERIN4' becomes 'ERINp4' 'MGZB' becomes 'GZB m' 'BAK664' becomes 'AK664 b' 'MAGBFA01' becomes 'AGBFmA01' '5021879949500' gets scanned correctly Anybody an idea how I could solve this problem?

• ASP.NET Connections Spring 2012 Talks and Code

  - by Stephen.Walther

  Thank you everyone who attended my ASP.NET Connections talks last week in Las Vegas. I’ve attached the slides and code for the three talks that I delivered: Using jQuery to interact with the Server through Ajax– In this talk, I discuss the different ways to communicate information between browser and server using Ajax. I explain the difference between the different types of Ajax calls that you can make with jQuery. I also discuss the differences between the JavaScriptSerializer, the DataContractJsonSerializer, and the JSON.NET serializer. ASP.NET Validation In-Depth– In this talk, I distinguish between View Model Validation and Domain Model Validation. I demonstrate how you can use the validation attributes (including the new .NET 4.5 validation attributes), the jQuery Validation library, and the HTML5 input validation attributes to perform View Model Validation. I then demonstrate how you can use the IValidatableObject interface with the Entity Framework to perform Domain Model Validation. Using the MVVM Pattern with JavaScript Views – In this talk, I discuss how you can create single page applications (SPA) by taking advantage of the open-source KnockoutJS library and the ASP.NET Web API. Be warned that the sample code is contained in Visual Studio 11 Beta projects. If you don’t have this version of Visual Studio, then you will need to open the code samples in Notepad. Also, I apologize for getting the code for these talks posted so slowly. I’ve been down with a nasty case of the flu for the past week and haven’t been able to get to a computer.

• Bandwidth Control on our Internet Connection

  - by AlamedaDad

  Hi all, I have Covad dual/bonded T1 service in our office coming through a Cisco 1841 and then through a Sonicwall 3060Pro/Enhanced SW firewall. The problem I'm looking for some input on is how to limit the amount of bandwidth any single user/PC can user for downloading a file from the Internet. It's become an issue that when one person happens to download let's say an ~300MB file, normal internet access for the other employees slows to a crawl. I've seen through MRTG that in fact usage of the circuit jumps to the full 3mb for the duration of the download and then drops. Is it possible to control this? I'm not familiar with QOS or the like so I'm not sure. Any help on this would be appreciated. Thanks...Michael

• How do I classify using GLCM and SVM Classifier in Matlab?

  - by Gomathi

  I'm on a project of liver tumor segmentation and classification. I used Region Growing and FCM for liver and tumor segmentation respectively. Then, I used Gray Level Co-occurence matrix for texture feature extraction. I have to use Support Vector Machine for Classification. But I don't know how to normalize the feature vectors. Can anyone tell how to program it in Matlab? To the GLCM program, I gave the tumor segmented image as input. Was I correct? If so, I think, then, my output will also be correct. My glcm coding, as far as I have tried is, I = imread('fzliver3.jpg'); GLCM = graycomatrix(I,'Offset',[2 0;0 2]); stats = graycoprops(GLCM,'all') t1= struct2array(stats) I2 = imread('fzliver4.jpg'); GLCM2 = graycomatrix(I2,'Offset',[2 0;0 2]); stats2 = graycoprops(GLCM2,'all') t2= struct2array(stats2) I3 = imread('fzliver5.jpg'); GLCM3 = graycomatrix(I3,'Offset',[2 0;0 2]); stats3 = graycoprops(GLCM3,'all') t3= struct2array(stats3) t=[t1;t2;t3] xmin = min(t); xmax = max(t); scale = xmax-xmin; tf=(x-xmin)/scale Was this a correct implementation? Also, I get an error at the last line.
