  • Simulink: type consistency errors

    - by stanigator
    Using this Simulink model file as a reference, I'm trying to figure out the two following errors: I have no idea what has gone wrong with the data type consistency/conversion problems. Do you know what the error messages mean exactly in the context of a model? It would be great to get an interpretation of the problem to solve it. Thanks in advance.

  • How does SimpleWorkerRequest associate MIME types with extensions?

    - by Justin Dearing
    I was serving html referencing svg files in Cassini, and having problems since the mime type was not being sent properly. I ended up writing my own port of Cassini that set the extension based on mime type. After a good night of sleep I realized that there might be some sort of registry key or config file where I can configure custom mime types for SimpleWorkerRequest, the .NET class that serves content through Casinni. However, I don't know what that is.

  • dz's Open Flash Chart 2 disabling animation problem (Rails)

    - by greg
    How to disable the startup animation in OFC2? Since I started using the dz build, the on-show animation is on by default, which sucks quite a lot. Neither of these work: graph.animate=false graph.on_show=false Also, dz's build implements the tooltip hover support poorly - the tooltip continues to hover even when the cursor is on another flash object. Has anyone overcome these problems?

  • Auto-scaffolding an "index" view in ASP.NET MVC

    - by DanM
    I'm trying to write an auto-scaffolder for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. Here's what I have so far: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; // Should be generic! var properties = items.First().GetMetadata().Properties .Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)); %> <table> <tr> <% foreach(var property in properties) { %> <th> <%= property.DisplayName %> </th> <% } %> </tr> <% foreach(var item in items) { %> <tr> <% foreach(var property in properties) { %> <td> <%= Html.Display(property.DisplayName) %> // This doesn't work! </td> <% } %> </tr> <% } %> </table> Two problems with this: I'd like it to be generic. So, I'd like to replace var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; with var items = (IQueryable<T>)Model; or something to that effect. The <td> elements are not working because the Html in <%= Html.Display(property.DisplayName) %> contains the model for the view, which is a collection of items, not the item itself. Somehow, I need to obtain an HtmlHelper object whose Model property is the current item, but I'm not sure how to do that. How do I solve these two problems?

  • Tomcat threads vs Java threads

    - by black666
    When using java threads, one has to take care of the basic problems that come with concurrency through synchronization etc. AFAIK Tomcat also works with threads to handle its workload. Why is it, that I don't have to think about making my code threadsafe when it is running in Tomcat?

  • Doubt about adopting CI (Hudson) into an existing automated Build Process (phing, svn)

    - by maraspin
    OUR CURRENT BUILD PROCESS We're a small team of developers (2 to 4 people depending on project) who currently use Phing to deploy code to a staging environment, before going live. We keep our code in a SVN repo, where the trunk holds current active development and, at certain times, we do make branches that we test and then (if successful), tag and export to the staging env. If everything goes well there too, we finally deploy'em in production servers. Actions are highly automated, but always triggered by human intervention. THE DOUBT We'd now like to introduce Continuous Integration (with Hudson) in the process; unfortunately we have a few doubts about activity syncing, since we're afraid that CI could somewhat interfere with our build process and cause certain problems. Considering that an automated CI cycle has a certain frequency of automatically executed actions, we in fact only see 2 possible cases for "integration", each with its own problems: Case A: each CI cycle produces a new branch with its own name; we do use such a name to manually (through phing as it happens now) export the code from the SVN to the staging env. The problem I see here is that (unless specific countermeasures are taken) the number of branches we have can grow out of control (let's suppose we commit often, so that we have a fresh new build/branch every N minutes). Case B: each CI cycle creates a new branch named 'current', for instance, which is tagged with a unique name only when we manually decide to export it to staging; the current branch, at any case is then deleted, as soon as the next CI cycle starts up. The problem we see here is that a new cycle could kick in while someone is tagging/exporting the 'current' branch to staging thus creating an inconsistent build (but maybe here I'm just too pessimist, since I confess I don't know whether SVN offers some built-in protection against this). With all this being said, I was wondering if anyone with similar experiences could be so kind to give us some hints on the subject, since none of the approaches depicted above looks completely satisfing to us. Is there something important we just completely left off in the overall picture? Thanks for your attention &, in advance, for your help!

  • How do I rollback capistrano tasks upon failure?

    - by dchua
    In my Capistrano deploy.rb, I have a couple of daemons like delayed_jobs and fetcher, starting and stopping depending on where they are in the deployment process. This method would create problems if a deployment fails, because the daemons wouldn't be managed properly (ie. two processes spawned instead of one, or processes were shutdown without restarting itself until the next deployment). Is there anyway to prevent this from happening like a rollback code? How is deployment of daemons normally done over capistrano?

  • Pros and cons of distributed revision control systems?

    - by Ludwig Weinzierl
    What are the advantages and disadvantages of distributed revision control systems? If you have any experience with distributed systems like Git, Mercurial, Plastic SCM, etc. please share your experience. Tell us what worked well and where problems arose. I'm particularly interested to hear about the use of distributed systems in traditional, commercial, non-open source projects but answers about other uses are also welcome.

  • How to migrate from SVN to GIT Locally

    - by Guilherme
    I'm working on a project that initially used Subversion, but the remote repository was removed and i don't want to use Subversion any more. I want to migrate it to git. There's a way to do it without the remote repository, keeping all revisions history (without doing a git init .)? I've already made a subversion to git migration with git-svn with no problems it on other projects, but they were on remote repository and i cannot find any info about migrating it locally.

  • TimeZoneInfo to TIME_ZONE_INFORMATION structure

    - by jaircazarin-old-account
    Hey, I've a TimeZoneInfo object and from this one I want to create a TIME_ZONE_INFO struct. Bias, StandardDate and Daylightdate are pretty easy to obtain. However, I'm having problems getting standardbias and daylightbias. So the question is, How can I get the standardbias from a TimeZOneInfo object and how can I get the same thing for daylightbias (there is a AdjustmentRule.DaylightDelta, but as you can see I need the offset not the delta). Thanks.

  • Portable shebang line

    - by Mike
    #!/usr/bin/perl This is the shebang line to a lot of scripts I'm writing lately. Hard coding the path of the binary seems like it could create some problems. For instance, if one of my users has Perl installed at /something_else/bin then they'd have to change all the shebangs. I've seen some tools that will automatically replace the shebangs, but I'm wondering if there is something simpler.
