  • R implementation of sorting by reversals

    - by user1357015
    I was wondering if there is an implementation in R where it sorts a permutation of n numbers into the original 1...n sequence and provides the number of reversals needed. Eg an implementation of the "sorting by reversals" or "sorting by translocation" as outlined in this ppt. Specifically, I have a permutation of a sequence of n elements, pi(n), and I want to figure out how close it is to the original sequence. The number of reversals seems a good metric. Thanks!

  • MVC3 - render view that is not a method in a controller

    - by scoo-b
    I don't know how to best describe my requirement, but here goes. I'm trying to render a view from the following controller/model in a nopCommerce application: CustomerController.cs snippet: [NonAction] protected CustomerNavigationModel GetCustomerNavigationModel(Customer customer) { var model = new CustomerNavigationModel(); model.HideAvatar = !_customerSettings.AllowCustomersToUploadAvatars; model.HideRewardPoints = !_rewardPointsSettings.Enabled; model.HideForumSubscriptions = !_forumSettings.ForumsEnabled || !_forumSettings.AllowCustomersToManageSubscriptions; model.HideReturnRequests = !_orderSettings.ReturnRequestsEnabled || _orderService.SearchReturnRequests(customer.Id, 0, null).Count == 0; model.HideDownloadableProducts = _customerSettings.HideDownloadableProductsTab; model.HideBackInStockSubscriptions = _customerSettings.HideBackInStockSubscriptionsTab; return model; } CustomerNavigationModel.cs: public partial class CustomerNavigationModel : BaseNopModel { public bool HideInfo { get; set; } public bool HideAddresses { get; set; } public bool HideOrders { get; set; } public bool HideBackInStockSubscriptions { get; set; } public bool HideReturnRequests { get; set; } public bool HideDownloadableProducts { get; set; } public bool HideRewardPoints { get; set; } public bool HideChangePassword { get; set; } public bool HideAvatar { get; set; } public bool HideForumSubscriptions { get; set; } public CustomerNavigationEnum SelectedTab { get; set; } } public enum CustomerNavigationEnum { Info, Addresses, Orders, BackInStockSubscriptions, ReturnRequests, DownloadableProducts, RewardPoints, ChangePassword, Avatar, ForumSubscriptions } MyAccountNavigation.cshtml snippet: @model CustomerNavigationModel @using Nop.Web.Models.Customer; @if (!Model.HideInfo) { <li><a href="@Url.RouteUrl("CustomerInfo")" class="@if (Model.SelectedTab == CustomerNavigationEnum.Info) {<text>active</text>} else {<text>inactive</text>}">@T("Account.CustomerInfo")</a></li>} Views: @Html.Partial("MyAccountNavigation", Model.NavigationModel, new ViewDataDictionary()) I am aware that it is unable to render MyAccountNavigation because it doesn't exist in the controller. However, depending on which page the syntax is placed it works. So is there a way to achieve that without changing the code in the controller? Thanks in advance.

  • Writing OpenGL enabled GUI

    - by Jaen
    I am exploring a possibility to write a kind of a notebook analogue that would reproduce the look and feel of using a traditional notebook, but with the added benefit of customizing the page in ways you can't do on paper - ask the program to lay ruled paper here, grid paper there, paste an image, insert a recording from the built-in camera, try to do handwriting recognition on the tablet input, insert some latex for neat formulas and so on. I'm pretty interested in developing it just to see if writing notes on computer can come anywhere close to the comfort plain paper + pencil offer (hard to do IMO) and can always turn it in as a university C++ project, so double gain there. Coming from the type of project there are certain requirements for the user interface: the user will be able to zoom, move and rotate the notebook as he wishes and I think it's pretty sensible delegate it to OpenGL, so the prospective GUI needs to work well with OGL (preferably being rendered in it) the interface should be navigable with as little of keyboard input as user wishes (incorporating some sort of gestures maybe) up to limiting the keyboard keys as modifiers to the pen movements and taps; this includes tablet and possible multitouch support the interface should keep out of the way where not needed and come up where needed and be easily layerable the notebook sheet itself will be a container for objects representing the notebook blurbs, so it would be nice if the GUI would be able to overlay some frames over the exact parts of the OpenGL-drawn sheet to signify what can be done with given part (like moving, rotating, deleting, copying, editing etc.) and it's extents In terms of interface it's probably going to end up similar to Alias' Sketch Book Pro: [picture][http://1.bp.blogspot.com/_GGxlzvZW-CY/SeKYA_oBdSI/AAAAAAAAErE/J6A0kyXiuqA/s400/Autodesk_Alias_SketchBook_Pro_2.jpg] As far as toolkits go I'm considering Qt and nui, but I'm not really aware how well would they match up the requirements and how well would they handle such an application. As far as I know you can somehow coerce Qt into doing widget drawing with OpenGL, but on the other hand I heard voices it's slot-signal framework isn't exactly optimal and requires it's own preprocessor and I don't know how hard would be to do all the custom widgets I would need (say color-wheel, ruler, blurb frames, blurb selection, tablet-targeted pop-up menu etc.) in the constraints of Qt. Also quite a few Qt programs I've had on my machine seemed really sluggish, but it may be attributed to me having old PC or programmers using Qt suboptimally rather to the framework itself. As for [nui][http://www.libnui.net/] I know it's also cross-platform and all of the basic things you would require of a GUI toolkit and what is the biggest plus it is OpenGL-enabled from the start, but I don't know how it is with custom widgets and other facets and it certainly has smaller userbase and less elaborate documentation than Qt. The question goes as this: Does any of these toolkits fulfill (preferably all of) the requirements or there is a well fitting toolkit I haven't come across or maybe I should just roll up my sleeves, get SFML (or maybe Clutter would be more suited to this?) and something like FastDelegates or libsigc++ and program the GUI framework from the ground up myself? I would be very glad if anyone had experience with a similar GUI project and can offer some comments on how well these toolkits hold up or is it worthwhile to pursue own GUI toolkit in this case. Sorry for longwindedness, duh.

  • Python templates for huge HTML/XML

    - by newtover
    Hello, Recently I needed to generate a huge HTML page containing a report with several thousand row table. And, obviously, I did not want to build the whole HTML (or the underlying tree) in memory. As result, I built the page with the old good string interpolation, but I do not like the solution. Thus, I wonder whether there are Python templating engines that can yield resulting page content by parts.

  • How to generate an Intent that jumps into a specific short message conversation?

    - by Janusz
    I would like to create an Intent that opens the messages application in a specific conversation. If a short message notification is clicked Logcat reveals the following: INFO/ActivityManager(31909): Starting activity: Intent { act=android.intent.action.VIEW dat=content://mms-sms/conversations/3 flg=0x34000000 cmp=com.android.mms/.ui.ConversationList bnds=[0,586][600,682] } This brought me a little bit further using content://mms-sms/conversations/3 as the data starts up the messages app in the correct conversation. I now only need to find out which conversation a message belongs to.

  • Path variable to mso.dll and msoutl.olb

    - by Stefanie
    Hey, I'm trying to develop a toolbar for Microsoft Outlook. For getting it to work I need mso.dll and msoutl.olb as an import. My problem is: the path is hardcoded , but it varies for every OS and of course if someone doesn't install Office to the default path. I tried it this way http://support.microsoft.com/kb/234788/en-us/ but it didn't work, because I couldn't get the return value I needed (OK, after four type conversions but I thought there had to be a better way ;) ) Thanks for helping

  • Is it possible to get a graphical representation of gprof results?

    - by Werner
    Hi, I am interested in getting the profiling of some number crunching program. I compiled it with -g and -pg options and linked it and got it gmon.out. After reading the info (plain text) it looks a bit ugly. I wonder if there are some open source tools for getting a graphical representation of the 10 functions where the program spends the most of the time as well as a flux diagram. Thanks

  • How to replicate data with memcache

    - by Industrial
    Hi everyone, I am trying to find good resources on best practices to data replication across memcache servers. What I want to accomplish is that if one of my servers in my pool goes down, the next server in line already has the info set. I have found "repcached" but since I run a WIN32 test environment, I have been unable to install it. So what's our alternatives on how to replicate data between servers? Thanks,

  • Is there a way to have three way habtm associations in rails / activerecord?

    - by txwikinger
    Often three (or more) way associations are needed for habtm associations. For instance a permission model with roles. A particular area of functionality has many users which can access many areas. The permissions on the area are setup via roles (habtm) The user/roles association is also habtm The permissions (read, write, delete, etc) are habtm towards roles. How would that be best done with rails/activerecord?
