• Expert system for writing programs?

  - by aaa

  I am brainstorming an idea of developing a high level software to manipulate matrix algebra equations, tensor manipulations to be exact, to produce optimized C++ code using several criteria such as sizes of dimensions, available memory on the system, etc. Something which is similar in spirit to tensor contraction engine, TCE, but specifically oriented towards producing optimized rather than general code. The end result desired is software which is expert in producing parallel program in my domain. Does this sort of development fall on the category of expert systems? What other projects out there work in the same area of producing code given the constraints?

• Is C# WebAPI worth it? Can I use standart MVC4 to create my API?

  - by Steve

  I need to build a massive API and I'm trying out WebAPI instead of default MVC4 projects and it seems that it just makes things more difficult. Can have only 4 methods in controller Get, Post, Put, Delete, if I want more I need to modify route for that particular method FluentValidation won't work with WebAPI so I need to use DataAnnotations which I really don't want to. Can't use dynamic return data-types My question is: Would it really be that bad if I would use MVC4 project and use default ActionResults that return Json? What are real advantages of using WebAPI, why did they even made them in the first place if you can easily convert your project to API?

• How to deal with files that are relevant to version control, but that frequently change in irrelevant ways?

  - by Jens Mühlenhoff

  .dproj files are essential for Delphi projects, so they have to be under version control. These files are controlled by the IDE and also contain some information that is frequently changed, but totally irrelevant for version control. For example: I change the start parameters of the application frequently (several times a day), but don't want to accidently commit the project file if only the part dealing with the start parameters has changed. So how to deal with this situation? A clean solution would be to take the file apart, but that isn't possible with the Delphi IDE AFAIK. Can you ignore a specific part of a file? We're using Subversion at the moment, but may migrate to Git soon.

• spring mvc nested model validation

  - by hguser

  I have two models : User,Project public class Project{ private int id; @NotEmpty(message="Project Name can not be empty") private String name; private User manager; private User operator; //getter/setter omitted } public class User{ private int id; private String name; //omit other properties and getter/setter } Now, when I create a new Project, I will submit the following parameters to ProjectController: projects?name=jhon&manager.id=1&operator.id=2... Then I will create a new Project object and insert it to db. However I have to validate the id of the manager and operator is valid,that's to say I will validate that if there is matched id in the user table. So I want to know how to implement this kind of validation?

• design question for transportation agency/workflow system

  - by George2

  Hello everyone, I am designing a transportation agency/workflow system, and it including 3 types of people, customer who requests to transport some stuff, drivers who deliver the stuff, and truck manager who manages transport source/destination truck coordination and communicates/organizes drivers. The system is expected to be a web site, and 3 kinds of people could use the web site to submit request, accept request, monitor status of specific stuff transportation, etc. The web site is more like an open agency or a workflow system. I am wondering whether there are any existing technologies, tools or projects (better to be open source, but not a must) which I could build my application faster based on? I prefer to use .Net technologies, but not a must. thanks in advance, George

• How the hell do you get clients to use your bug tracking system?

  - by louism

  on larger projects i use a simple bug tracking system thats designed to be used by clients i have a lot of trouble convincing clients to use it (they send bug reports via email) does anyone have any strategies they can suggested? also, i have been playing around with a theory as to why this is the case; it goes like this: asking a client to log a bug is like taking your car to a mechanic for a service, and the mechanic hands you the engine oil and says "here, pop that in". basically, the client has paid you to do the work, logging a bug sounds too much like work, so they want you to do it thoughts? -- LM

• Time to ignore IE?

  - by Delan Azabani

  In this answer: http://stackoverflow.com/questions/2781013/does-anyone-have-a-easy-to-use-png-fix-for-ie/2781041#2781041 which got voted down considerably, I point out the need to ignore Internet Explorer, or at least its old version 6, for the following reasons: It is hard to hack for, and some features don't exist at all The more you hack for IE, the longer people blindly use it (vicious cycle) My website, azabani.com, doesn't hack for IE at all. The layout looks somewhat broken in the browser, and most of my projects require features not present in IE's codebase. I would like to know if you support my view, or if you share views with those who downvoted my answer.

• Publish web application from MSBuild Script using VS2010 targets resets working directory

  - by Raoul

  I am trying to automatically publish and deploy my .Net 4 web application automatically from a build script to be run by our continuous integration server. I am using the new _WPPCopyWebApplication target from VS2010 to perform the publish, however it appears to reset the current working directory of the msbuild project to c:\ this causes my prebuild steps to fail as they have relative paths to some external tools. The task I am running from our master.build file is as follows: <Target Name="PublishWeb"> <MSBuild Projects="$(ProjectPath)" Targets="ResolveReferences;_WPPCopyWebApplication" Properties="WebProjectOutputDir=$(DeployPath);OutDir=$(TempOutputFolder)$(WebOutputFolder)\;OutputPath=$(ProjectPath)\bin\Debug;" /> </Target> This does not happen when using the legacy _CopyWebApplication. Does anyone have any idea how to resolve this problem?

• Please recommend good books for telemetry / SCADA system design & programming

  - by Mawg

  I am looking at several projects, all with roughly the same fucntionality. Some instruments collect some data (or control some functionality). They commmunicate by Internet (Etehrnet/wifi/GPRS/sasatellite) with a databse server which stores the measurements and provides a browser based means of qeurying the data, prodcuing reports, etc (and possibly also allows control of the remote equipment). Can anyone recommend a good book describing an approach to developing such a software architecture, keeping it generic, which tools, languages. test methods, etc to use? (note to self: ask a similar question about possible existing frameworks)

• .NET Deployment of Interface/Classes for Command Pattern Question

  - by Jonno

  In theory I would like to produce 2 projects: 1) Asp.net (Sever A) 2) DAL running (Server B) I would like to utilise command objects to comunicate with the DAL. ASP.net instantiates a command class e.g. CmdGetAllUsers which impliments IMyCommand interface and sends it to the DAL (using ASMX or WCF). My question is: Would the class definition of CmdGetAllUsers need to exist on the DAL server? Or would having the interface definition be enough? My goal is to reduce the need to redeploy the DAL code, and have it as a fairly simple pass-through layer. Many thanks for your time.

• How to handle different roles with different previliges in PHP?

  - by user261002

  I would like to know how we can create different "user Roles" for different users in PHP. example: Administrator can create all types of users, add, view, manipulate data, delete managers, viewers, and workers, etc managers can only create, workers and viewers, can add and view data, workers can't create new users, but can only add data and view data, viewers can only view data that has been added to the DB by workers, managers and administrators. I though its better to use different sessions like : $_SESSION['admin'] $_SESSION['manager'] $_SESSION['worker'] $_SESSION['viewvers'] and for every page check which of them have a true or yes value, but I want to know how do they do it in real and big projects??? is there any other way???

• Lines-of-code counting for many C# solutions

  - by Eric

  I am currently researching a solution for counting lines of code in C#. I pretty much need a combination of the following two tools: http://richnewman.wordpress.com/2007/07/01/c-and-vbnet-line-count-utility/ http://www.locmetrics.com/index.html My problem is that I need to recursively scan a folder containing a lot of visual studio solutions. So can't really use the first tool without any major work on its code, as it's only able to scan a single solution at a time. But I also need to split the results for each solution, preferably even the contained projects. This disqualifies the second tool I found. I also found NDepend which suffers from the same problem. Do you know of any free tools that do what I need? I am unable to find anything suitable.

• Rails plugin for generating dynamic / ajax crud interfaces compatible with Rails 3 beta?

  - by mikehansen

  Anyone know of some good gems or plugins to create dynamic / ajax crud interfaces for Rails 3 projects? I know active scaffold was popular before and it's been awhile since I have used it / any other gems similar to this (I usually just write it myself). I like the direction that the formtastic gem (http://github.com/justinfrench/formtastic) is headed and wonder what else people are combining with it. Also I like the generators approach that Ryan Bates uses and he appears to be making updates for Rails 3. Anything else I am missing here? (I am also open to gems not compatible with Rails 3 too I guess, I can always make a contribution and try to help them get to the next phase. ;)) PS - Really stackoverflow, only one hyperlink?? lame.

• What JavaScript framework to choose? JQuery+JQueryUI, Dojo or ExtJS?

  - by Ivan

  I am choosing a JavaScript Framework to master and use extensively in all my future projects (mostly working with relational DATA, web services via AJAX and implementing complex rich client UIs). Now I am choosing between JQuery+JQueryUI, Dojo and ExtJS. What should I choose? 1st priority is power and functionality, 2nd priority is beauty and maintainability of code and ease of use, 3rd priority is flexibility and modularity, 4th priority is speed and size. IE compatibility hardly matters, I'd like it to be modern, legacy-free and standard-conformant.

• javax.servlet import cannot be resolved after moving web servlet

  - by Michael Kjörling

  I have written a small web servlet to run under Tomcat, using Eclipse Helios. In its old, non-source-controlled location, everything was fine, but now I need to add this to our source control system. Moving the old files out of the way, creating a new workspace, setting up the server connection and copying and importing the existing projects into the new workspace all worked fine once I figured out how to do it, but I can't get the servlet to build. Instead, I get a whole bunch of cannot be resolved to a type errors talking about various servlet class types; HttpServlet, HttpServletRequest, ServletException, etc. Another error that is almost certainly related is The import javax.servlet cannot be resolved. I am obviously missing something very basic, but I'm new to this (and not having the terminology really down pat probably doesn't help me Google for an answer). Any suggestions as to what I might be missing would be greatly appreciated.

• After pip installing uWSGI there's no /etc/uwsgi/ directory - how can I use apps-enabled?

  - by orokusaki

  I've been using apt-get install uwsgi to install uWSGI. Today, I realized I needed a feature that's not available until uWSGI 1.1, and Ubuntu 12.04.1 doesn't have anything after 1.0.x, at least according to my apt-get install uwsgi=1.1 attempt. So, I used: pip install http://projects.unbit.it/downloads/uwsgi-lts.tar.gz After doing so, I get a message prescribing the use of /usr/local/bin/uwsgi to launch the program. I'm not a guru when it comes to compiling from source, but my understanding is that when you do so, nothing will be changed in the /etc/ directory. Is this correct? If not, why don't I have a /etc/uwsgi/ directory and, more specifically, a /etc/uwsgi/apps-enabled/ directory? Should I simply create the directories when installing uWSGI from source? I was hesitant to do so, considering there is no mention of this in the docs (I don't want something that accidentally works, etc.).

• Any homologue of InternalsVisibleToAttribute, but for internal classes?

  - by Will Marcouiller

  In my most recent question: Unit Testing Best Practice? / C# InternalsVisibleTo() attribute for VBNET 2.0 while testing?, I was asking about InternalsVisibleToAttribute. I have read the documentation on how to use it, and everything is fine and understood. However, I can't instantiate my class Groupe from my Testing project. I want to be able to instantiate my internal class in my wrapper assembly, from my testing assembly. Any help is appreciated! EDIT Here's the compile-time error I get when I do try to instantiate my type: Erreur 2 'Carra.Exemples.Blocs.ActiveDirectory.Groupe' n'est pas accessible dans ce contexte, car il est 'Private'. C:\Open\Projects\Exemples\Src\Carra.Exemples.Blocs.ActiveDirectory\Carra.Exemples.Blocs.ActiveDirectory.Tests\GroupeTests.vb 9 18 Carra.Exemples.Blocs.ActiveDirectory.Tests (This says that my type is not accessible in this context, because it is private.) But it's Friend (internal)!

• Remove all references to a DLL across all application domains

  - by ck

  I have a web application that dynamically loads assemblies based on database configuration entries to perform certain actions (dynamic plugin style architecture). The calls to the objects are in a Factory Pattern implementation, and the object is cached (in a static dictionary< within the Factory) as the calls can be made many thousands of times in a minute. The calls to this factory are made from both the main web application and a number of webservices, some in different assemblies/projects. When I need to update one of these DLLs, I have to recycle IIS to get the DLL released. As this has an impact on another application on the server, I wanted to know if there was a way I could release the DLL without restarting IIS?

• How to name variables wich are structs

  - by evilpie

  Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non captialized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

• Best Ruby ORM for Wrapping around Legacy SQL Server Database?

  - by Technocrat

  Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support SQL Server through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in SQL Server. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the SQL Server app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with SQL Server but never to do anything quite like this. Any suggestions?

• When using Microsoft Test Manager 2010 with SfTS, how do QA engineers know what tests they have to run?

  - by MADCookie

  We are moving our projects to TFS 2010 using the SfTS v3 (Scrum for Team System) template. We need to understand how Microsoft Test Manager is supposed to be used in this Scrum process. Specific scenario & question: The QA manager uses Test Manager to create Acceptance Test Work Items (WIs). These new WIs are created and "assigned to" him. The manager doesn't run all the tests, instead he wants to give that responsibility to his staff. How is a QA engineer supposed to know that he has tests to run? Everything says it is assigned to the manager.
