  • how to develop a program to minimize errors in human transcription of hand written surveys

    - by Alex. S.
    I need to develop custom software to do surveys. Questions may be of multiple choice, or free text in a very few cases. I was asked to design a subsystem to check if there is any error in the manual data entry for the multiple choices part. We're trying to speed up the user data entry process and to minimize human input differences between digital forms and the original questionnaires. The surveys are filled with handwritten marks and text by human interviewers, so it's possible to find hard to read marks, or also the user could accidentally select a different value in some question, and we would like to avoid that. The software must include some automatic control to detect possible typing differences. Each answer of the multiple choice questions has the same probability of being selected. This question has two parts: The GUI. The most simple thing I have in mind is to implement the most usable design of the questions display: use of large and readable fonts and space generously the choices. Is there something else? For faster input, I would like to use drop down lists (favoring keyboard over mouse). Given the questions are grouped in sections, I would like to show the answers selected for the questions of that section, but this could slow down the process. Any other ideas? The error checking subsystem. What else can I do to minimize or to check human typos in the multiple choice questions? Is this a solvable problem? is there some statistical methodology to check values that were entered by the users are the same from the hand filled forms? For example, let's suppose the survey has 5 questions, and each has 4 options. Let's say I have n survey forms filled in paper by interviewers, and they're ready to be entered in the software, then how to minimize the accidental differences that can have the manual transcription of the n surveys, without having to double check everything in the 5 questions of the n surveys? My first suggestion is that at the end of the processing of all the hand filled forms, the software could choose some forms randomly to make a double check of the responses in a few instances, but on what criteria can I make this selection? This validation would be enough to cover everything in a significant way? The actual survey is nation level and it has 56 pages with over 200 questions in total, so it will be a lot of hand written pages by many people, and the intention is to reduce the likelihood of errors and to optimize speed in the data entry process. The surveys must filled in paper first, given the complications of taking laptops or handhelds with the interviewers.

  • Extracting multiple values from a string with RegEx

    - by Toni Frankola
    I have an input string that's generated as in following example: string.Format("Document {0}, was saved by {1} on {2}. The process was completed {3} milliseconds and data was received.", "Document.docx", "John", "1/1/2011", 45); Generate string looks like this then: Document Document.docx, was saved by John on 1/1/2011. The process was completed 45 milliseconds and data was received. Once such a string is received from a different application, what would be the easiest way to parse with regex and extract values Document.docx, John, 1/1/2011, 45 from it. I am looking for the easiest way to do this as we will have to parse a number of different input strings.

  • Starting self hosted WCF services on demand

    - by Pieter
    Is it possible to start self hosted WCF services on demand? I see two options to accomplish this: Insert a listener in the self hosted WCF's web server and spin up a service host when a request for a specific service comes in, before WCF starts looking for the existence of that endpoint; or Integrate a web service in process, start a service host for a request if it isn't running yet and redirect the request to that service host (like I suspect IIS does). I cannot use IIS or WAS because the web services need to run in process with the UI business logic. Which is feasible and how can I accomplish this? EDIT: I cannot just start the service hosts because there are hundreds, most (about 95%) of which are (almost) never used but need to be available. This is for exposing a business logic layer of 900 entities.

  • UIActivityIndicator not working properly?

    - by medma
    Hello frends, I have a problem regarding UIActivityIndicator. I applied "[spinner startAnimating]" at the IBAction on a button and then doing some process. After the process activityindicator should be stopped and then navigate to another view. But the activity indicator does not appear. When I remove the line "[spinner stopAnimating]" then the indicator appears but not at the instant button is pressed. It appears just before the other view loads, and apparently does not appear, I mean it does not appear but if we see very carefully then only it appears for an instant. Thanx in advance for any answer.

  • Vim: multi-file editing - having different makes in different splits

    - by gmatt
    I'm a recent vim convert (from fancy IDEs like eclipse.) I love the :make command in vim and use it extensively; however I also like to edit multiple projects (with separate makefiles.) So usually to edit more than one project I will do pushd project1 vim project1.cpp [suspend signal] pushd ../project2 vim project2.cpp and now I can switch between the two projects with ctrl+z i.e. suspend signal, and fg. When this becomes an issue is when I want to open one project in the context of another so I can do copy/pasting. So if instead in the above I do pushd project1 vim project1.cpp :vsp ../project2/project2.cpp I can edit both concurrently in the same vim process, however I can't effectively build one or the other with the :make command, it will only build project 1. Does anyone have some kind of scheme that gives them the best of both worlds: being able to edit concurrently while still being able to build multiple projects with the :make command all from the same vim process?

  • Unable to boot from USB boot drive for AMD Athlon 64

    - by Nagarjun
    I am trying to install Ubuntu 13.04 ISO for AMD64 Athlon processor using USB drive (8GB). I did create a bootable USB using the USB installer from Win7 intel 32bit processor (followed steps from here: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows). This USB is unable to boot on my AMD64 bit processor. The bios is able to detect the USB and once I change the boot order to USB and save exit from bios, I get a message saying "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS CONTINUE" and unable to proceed further. However earlier to this I have successfully installed Ubuntu 13.04 on to my laptop which has Intel 32 bit core i5 processor with the same procedure but my desktop which has AMD64 is failing. I also tried to create the USB installer on my desktop which has the AMD64 bit processor and tried booting which also resulted in the same error. (My desktop currently has Win XP) Please help as I have run out of options. thanks, Nagarjun

  • Does booting a live USB cause writes to occur to it?

    - by InkBlend
    I know that Ubuntu will not and can not write to a live CD-R/DVD+-R when it is booting from it, as it is a read-only medium. However, the procedure (at least on the data level) for running Ubuntu off an optical disc is different from a USB drive, which is usually write-enabled. if I make a live USB, turn off persistent files, and boot from it, will any data be written to the USB drive (e.g. settings, error logs, temporary files)? Or will Ubuntu just read from it, nothing else?

  • Tips for a successful AppStore submission?

    - by Andrew Grant
    In a day or two I'll be ready to submit my iPhone app to the AppStore and I'm curious whether people who have gone through this process have any tips / suggestions for a smooth submission process. Here's things I've covered; No memory leaks Tested performance on an actual device Doesn't crash :) Using correct certificates / profile What I'm a little unsure about are how to configure the "Bundle Display Name" /"Bundle Identifier" and "Bundle Name" in info.plist. I understand the first is the text that's shown on the iPhone itself, but what about the last? Does this have to match Bundle Identifier? Are there any other things I should add to the info.plist? I've noticed that when built for Adhoc distribution my app does not have any author/title information in iTunes.

  • c# list<int> how to insert a new value in between two values

    - by gdubs
    so i have a list where i need to add new values constantly but when i do i need to increment it and insert it in between two values. List<int> initializers = new List <int>(); initializers.Add(1); initializers.Add(3); so initializers would have 1, 3 values. i would then process a new set of numbers. the initializers will need to have the values. 1, 5, 3, 7 and if i process another set of numbers it should become 1, 9, 5, 13, 3, 11, 7, 15 i know how to properly generate the new values inserted, i just need some help on inserting it in between the existing values of the initializers without having to add 2 or 3 more loops to move the values' positions.

  • IIS6 + PHP + FastCGI 500 Errors - Where do I start looking?

    - by Bertvan
    I've set up IIS6 with FastCGI to use php-cgi.exe. I have some php websites by external parties, that I'm trying to run in a test environment. One of the websites just plain gives me a FastCGI Error Page. Is there some way to enable logging somewhere so that I can get a bit more information on this problem? I have looked in - Eventlog - IIS Website log (c:\windows\system32\Logfiles) - PHP log But no results, except the IIS Website log mentions a return of a 500 page. Is there any other way to debug/check where things might be going wrong? Here is what the page looks like: FastCGI Error The FastCGI Handler was unable to process the request. Error Details: The FastCGI process exited unexpectedly Error Number: -1073741571 (0xc00000fd). Error Description: Unknown Error HTTP Error 500 - Server Error. Internet Information Services (IIS)

  • Creating compound applications in Windows 7

    - by Mmarquee
    I need to port a suite of Windows applications (running under XP with little security turned on) to Windows 7 with various levels of security, depending on how our clients may configure it. Each functional area is a seperate executable or DLL that is downloaded and registered by a central 'compound' application. This means that the different parts are all joined together to form in effect a large single application. My problem is that the compound application knows about the other applications via COM registery, either as a typelibrary or as OCXs, where appropriate. I have tried several questions here to try and solve the problems I am getting, but I don't seem to be able to get around the problem of needing elevated access to register applications and access the registry. Our clients will be expecting the same (relatively) seemless download and activation process as current under XP. So does anyone have a solution for registering typelibraries and OCX controls without need to go through an elevation process. Thanks in advance

  • How can I measure TForm deserialization time in Delphi?

    - by mjustin
    For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": before the beginning of the deserialization process after the completion of deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.

  • Deploying Asp.net MVC web application [migrated]

    - by Pankaj Upadhyay
    I have been trying to find a neat tutorial, guide or step by step instructions for deploying an Asp.net MVC3 webapp but have found nothing so far. Everyone talks about his version of the stroy and different type of MVC versions. Right now, I have build a simple Asp.net MVC web application which i need to deploy on my shared hosting account. In a very simple manner, I need to know which files should i copy. Do i upload everything in my webproject directory to the server including the controller directory, views, models, content and bin directory ?. What about the Global.asax, web.config, packages.config, myapp.publish.xml. In short, I have no idea which files should be uploaded and which should be not. I am sure of one thing that i need few(MVC and Razor dlls) following dlls in bin directory. Just treat me as someone who has never deployed any website NOTE:- I don't have VS SP1 installed and it doesn't install either. Basically i need a manual procedure.

  • Why does the token returned by LogonUser() in Win x64 not belong to LOCAL group?

    - by edwinbs
    Hi, I have a piece of code that calls LogonUser() followed by CreateProcessAsUser(). In Win32, the resulting process belongs to a user (say, TESTDOMAIN\user1) who belongs to the LOCAL group. However, in x64, the process owner does not belong to LOCAL. The owner still belongs to all other groups (Authenticated Users, Everyone, etc.) Does anyone know if this is a documented behavior change? Or am I supposed to put some special flag in x64 when calling LogonUser()? Thanks.

  • how to selfhost wcf without iis

    - by dotnetcoder
    Reading up on WCF we have self hosting option available , one limitation here is we have to manage the host process lifecycle ourselves. What I am exploring here is to run the service without IIS and do a self hosting. Few things come to mind - How will request management work here. In case of IIS it manages the request and give control to dotnet on a particular thread. In absence of IIS do we need to write code ourselves to manage incoming requests ( say on a tcp port ) or WCF provides some classes to manage request and spawn threads to process each thread. I am aware that in case of self hosting this needs to be a windows service. In case of self hosting how can me tap on the number of simultaneous requests on the sever , it can be managed by limiting the thread pool ? or we can configure this via wcf ? Thanks dc

  • Ridiculously Simple Erlang Question

    - by Aiden Bell
    Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and is there any guarantee of order when processing messages? ie. Received in order sent? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)
