  • 80 Years of Supplier Misinformation: How can Oracle Supplier Hub Help?

    - by Mala Narasimharajan
    By Mark Peachy       Well, we're down to the final week before this year's Oracle Open World conference kicks-off on Sunday and there's still plenty of work to be done to be ready in time.  One of the great benefits I think that attendees get from Open World is the opportunity to listen to other organizations talk about their implementation experiences.  Typically, these sessions provide hugely valuable insights that have been gained during a deployment, delivering a wealth of practical information on what it really takes to get an organization up and running with a new module or a revamped business process.And I'm not just saying this because we're lucky enough to have one of our early implementers join us for this year's Supplier Hub/Supplier Lifecycle Management MDM session!  With a multi-phased deployment underway, this customer is working to fix a long, 80-year history without much in the way of formal processes or tools to manage all of their accumulated supplier information.  Faced with a mess of supplier details, they had been challenged to efficiently track supplier spend, monitor performance, maintain qualification information or carry out meaningful risk analysis.  Join us on Wednesday to hear how they are addressing these issues and the plans they have to evolve their supplier management techniques - it's a great story.CON9242:  Oracle Supplier Lifecycle Management and Oracle Supplier Hub for Better Supply Base Management Wednesday, October 3rd at 1:15 PM                                                                                                                                                InterContinental Hotel, Sutter Suite

  • Do you know about the Visual Studio 2010 Database Projects Guidance?

    - by Martin Hinshelwood
    Early on in the Team System (now Visual Studio ALM) cycle a new product surfaced within Team System that was affectionately called “Data Dude”, but had the more formal name of “Visual Studio 2005 Team Edition for Database Professionals”. The purpose of this product was to try and make the database a “first class citizen” in the development world. Those that started using Visual Studio 2005 Team Edition for Database Professionals (Data Dude) loved it, but everyone else did not get it. The capabilities were a little patchy, but the one thing it did bring to the party was the ability to put your database schema under source control. This was revolutionary as previously your DBA sat as far away from the team as possible, and usually in a dark cupboard, now they could partake of all the goodness of Version Control, Work Item Tracking and automated builds. The problem was that the understanding required to manage these projects was very different to that needed previously. Then the Visual Studio ALM Rangers got a hold of it…and produced some of the best guidance available. Figure: Download the guidance from http://vsdatabaseguide.codeplex.com/ This guidance discusses scenarios and approaches of using the Database Projects in Visual Studio 2010 to help you use the tools more effectively and maximize their value to your organization This guidance is focused on these five areas: Solution and Project Management Source Code Control and Configuration Management Integrating External Changes with the Project System Build and Deployment Automation with Visual Studio Database Projects Database Testing and Deployment Verification Each of these areas has common guidance, usage scenarios, hands on labs, and lessons learned from real world engagements and the community discussions.   The guidance is broken down into three packages: Guidance documentation Hands-on-lab (HOL) documentation note: The documentation is available in XPS-only format packages or complete XPS,PDF,DOCX format packages HOL Package If you need assistance and no one else can help, then you may need to call the Visual Studio ALM Rangers. The Visual Studio ALM Rangers have the mission to provide out of band solutions for missing features or guidance. They are supported by Microsoft Product Group, Microsoft Consulting Services, Microsoft Most Valued Professionals (MVPs) and technical specialists from technology communities around the globe, giving you a real-world view from the field, where the technology has been tested and used. For more information on the Rangers please visit http://msdn.microsoft.com/en-us/vstudio/ee358786.aspx and for more a list of other Rangers projects please see http://msdn.microsoft.com/en-us/vstudio/ee358787.aspx.

  • Dadaism and Agility

    - by alexhildyard
    We all have our little bugbears, and something that has given me particular pause over the years is the place of Agility in the software development life cycle. While I have seen it used successfully on both small and Enterprise-level projects, I have also seen many instances in which long-standing technical debt has also originated under its watch. Ironically the problem in such cases seems to me not that the practitioners in question have failed to follow due process (Test, Develop, Refactor -- a common "what" of Agile), but basically that they have missed the point (the "why" of Agile). It's probably a sign of my age that I'm much more interested in the "why" than the "what", since I feel that the latter falls out naturally from the former, but that this is not a reciprocal relationship.Consider Dadaism, precursor to the Surrealist movement in the early part of the twentieth century. Anyone could stand up and proclaim he or she was Dada; anyone could write cut-ups, or pull words out a hat, or produce gibberish on duelling typewriters under the inspiration of Dada. And all that took place at such performances was a manifestation of Dada, and all the artefacts that resulted were also Dada. Hence one commentator's engimatic observation that 'when one speaks of Dada, then one speaks of Dada. But when one does not speak of Dada, one still speaks of Dada.'What is Dada? Literally, Dada is what you say it is. But that's also missing the point. Dada is about erecting a framework within which utterances like this are valid; Dada is about preparing a stage for itself. Dadaism exemplifies the purity of a process-driven ideology -- in fact an ideology that is almost pure process, with nothing extraneous in the way of formal method, and while perhaps Agile delivery should not embrace the liberties of Dadaism too literally, some of the similarities nevertheless are salutary.Agile -- like Dada -- is an attitude; it is about *being* agile; it is not really about doing a specific set of things that are somehow *part* of being Agile. It is an abstract base rather than an implementation, a characteristic rather than a factor. It is the pragmatic response to the need for change in the face of partial information, ephemeral requirements and a healthy dose of systematic uncertainty. In practice this will usually mean repeatedly making the smallest useful changes to a system, recognising that systems evolve, and that all change carries risk. It will usually mean that instead of investing effort in future-proofing a system against a known technology roadmap, one instead invests one's energies in the daily repetition and incremental development of processes best designed to accommodate change quickly. But though it may mean these things in practice, it isn't actually *about* either of these things; it's about the mindset, the attitude that conceives of such responses as sensible solutions given the larger and ultimately unclassifiable thing that constitutes the development lifecycle of a specific project.

  • Html.DropDownListFor() doesn't always render selected value

    - by Andrey
    I have a view model: public class LanguagesViewModel { public IEnumerable<LanguageItem> Languages { get; set; } public IEnumerable<SelectListItem> LanguageItems { get; set; } public IEnumerable<SelectListItem> LanguageLevelItems { get; set; } } public class LanguageItem { public int LanguageId { get; set; } public int SpeakingSkillId { get; set; } public int WritingSkillId { get; set; } public int UnderstandingSkillId { get; set; } public LanguagesViewModel Lvm { get; internal set; } } It's rendered with the following code: <tbody> <% foreach( var language in Model.Languages ) { Html.RenderPartial("LanguageItem", language); } %> </tbody> LanguageItem.ascx: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<HrmCV.Web.ViewModels.LanguageItem>" %> <tr id="lngRow"> <td class="a_left"> <%: Html.DropDownListFor(m => m.LanguageId, Model.Lvm.LanguageItems, null, new { @class = "span-3" }) %> </td> <td> <%: Html.DropDownListFor(m => m.SpeakingSkillId, Model.Lvm.LanguageLevelItems, null, new { @class = "span-3" }) %> </td> <td> <%: Html.DropDownListFor(m => m.WritingSkillId, Model.Lvm.LanguageLevelItems, null, new { @class = "span-3" })%> </td> <td> <%: Html.DropDownListFor(m => m.UnderstandingSkillId, Model.Lvm.LanguageLevelItems, null, new { @class = "span-3" })%> </td> <td> <div class="btn-primary"> <a class="btn-primary-l" onclick="DeleteLanguage(this.id)" id="btnDel" href="javascript:void(0)"><%:ViewResources.SharedStrings.BtnDelete%></a> <span class="btn-primary-r"></span> </div> </td> </tr> The problem is that upon POST, LanguageId dropdown doesn't render its previously selected value. While all other dropdowns - do render. I cannot see any differences in the implementation between them. What is the reason for such behavior?

  • How to read a barcode from an image

    - by tardate
    I'm seeking a library, technique or advice on how to read an EAN-13 barcode from an image (including ISBN,and ISSN encodings). The image would come from a mobile phone or webcam, so resolution may be quite poor and not well aligned. I'm specifically interested in something that could be used from ruby on rails, but answers for other languages are welcome. Open Source solutions preferred. Leading solutions so far: ZBar (previously known as Zebra - h/t @bgbg, @Natim) and ZXing (h/t @codr)

  • F# and OCaml

    - by Erik Forbes
    I hear that F# is derived from OCaml. How true is this statement? That is to say, are the resources available for learning OCaml useful to someone who wants to learn F#? What are the major differences between the two languages (aside from the fact that F# is .NET)?

  • C++ vs Matlab vs Python as a main language for Computer Vision Postgraduate

    - by Hough
    Hi all, Firstly, sorry for a somewhat long question but I think that many people are in the same situation as me and hopefully they can also gain some benefit from this. I'll be starting my PhD very soon which involve the fields of computer vision, pattern recognition and machine learning. Currently, I'm using opencv (2.1) C++ interface and I especially like its powerful Mat class and the overloaded operations available for matrix and image seamless operations and transformations. I've also tried (and implemented many small vision projects) using opencv python interface (new bindings; opencv 2.1) and I really enjoy python's ability to integrate opencv, numpy, scipy and matplotlib. But recently, I went back to opencv C++ interface because I felt that the official python new bindings were not stable enough and no overloaded operations are available for matrices and images, not to mention the lack of machine learning modules and slow speeds in certain operations. I've also used Matlab extensively in the past and although I've used mex files and other means to speed up the program, I just felt that Matlab's performance was inadequate for real-time vision tasks, be it for fast prototyping or not. When the project becomes larger and larger, many tasks have to be re-written in C and compiled into Mex files increasingly and Matlab becomes nothing more than a glue language. Here comes the sub-questions: For postgrad studies in these fields (machine learning, vision, pattern recognition), what is your main or ideal programming language for rapid prototyping of ideas and testing algorithms contained in papers? For postgrad studies, can you list down the pros and cons of using the following languages? C++ (with opencv + gsl + svmlib + other libraries) vs Matlab (with all its toolboxes) vs python (with the imcomplete opencv bindings + numpy + scipy + matplotlib). Are there computer vision PhD/postgrad students here who are using only C++ (with all its availabe libraries including opencv) without even needing to resort to Matlab or python? In other words, given the current existing computer vision or machine learning libraries, is C++ alone sufficient for fast prototyping of ideas? If you're currently using Java or C# for your postgrad work, can you list down the reasons why they should be used and how they compare to other languages in terms of available libraries? What is the de facto vision/machine learning programming language and its associated libraries used in your university research group? Thanks in advance.

  • WPF TextBox SpellChecking Problem

    - by Alex
    How can I change the spellchecking language of a WPF textbox to french using XAML? I tried this but it doesn't work. <TextBox AcceptsReturn="true" SpellCheck.IsEnabled="true" FontSize="12" BorderBrush="Blue" Height="100" Language="fr-fr" /> French is supposed to be one of the 4 supported languages for spellchecking in WPF so I don't understand why it doesn't work. I also tried fr-CA but it still won't work.

  • complete, monospaced Unicode font?

    - by nachik
    I'm looking for a good programming font that lets me add comments and string literals in Unicode, usually Japanese and Chinese along with some Latin and Cyrillic languages. So far the situation seems to be "complete, monospace, free, pick 2" and Google is failing me with this (maybe because there are no good ones?). The best I found is Arial Unicode but it's not monospace, which is a big nuisance for me and the editors I use. Not to mention Python indentation when I'm coding Python. (Links, edits are welcome)

  • Tips on a tool to measure code quality?

    - by Cristi Diaconescu
    I'm looking for a tool that can provide code quality metrics. For instance it could report very long functions (spaghetti code) very complex classes (which could contain do-it-all code) ... While we're on the (subjective:-) subject of code quality, what other code metrics would you suggest? I'm targetting C#/.NET code, but I'm sure this could extend to most programming languages.

  • perl: tk: a way/widget that allows pixel level control over the output

    - by chhh
    I want something like a canvas, but where i'd be able to manipulate pixels easily in addition to all the provided geometries, that can be drawn on canvas. Is it possible to embed something like GD::Image into a canvas? So then I maybe could make the image transparent and set some pixels in it (GD::Image-setPixel()) positioning it over the canvas? ps: well, that doesn't necessarily have to be perl, as there seem to be bindings for all the libs for most scripting (and not only) languages.

  • ActionScipt MouseEvent's CLICK vs. DOUBLE_CLICK

    - by TheDarkIn1978
    is it not possible to have both CLICK and DOUBLE_CLICK on the same display object? i'm trying to have both for the stage where double clicking the stage adds a new object and clicking once on the stage deselects a selected object. it appears that DOUBLE_CLICK will execute both itself as well as 2 CLICK functions. in other languages i've programmed with there was a built-in timers that set the two apart. is this not available in AS3?

  • codepad.org Perl runner limitations

    - by Lemurik
    Sometimes I see people use http://codepad.org as a way to quickly run/test their Perl snippets (it supports doing that with a wide variety of languages, from C to Scheme to Perl). It's pretty obious that there must be some limitations as to what code/features can be tested with codepad - does anyone know what those limitations are for Perl runner? I'll get the ball rolling on my own observation: not every CPAN module is avialable :(
