• Is there an image phase correlation library available for Python?

  - by kamasudra

  A project that involves image processing, i.e. to calculate the angular shift of the same image when shifted by a medium of certain Refractive Index. We have to build an app that correlates the 2 images (phase/2D correlation?) and then plot using Chaco and Mayavi (2 libraries in Python). Is there any other existing template software (FOSS) that we can base our app on, or use it as a reference?

• Can a System Analyst come outside of programming?

  - by WeNeedAnswers

  Back in the day, if you wanted to be a Systems Analyst you had to work up the ranks from humble programmer. But these days there are University Courses/Programmes based on this topic alone. Is it thus valid for a graduate or post graduate to come into the world and just do systems analyst without doing the graft of being a programmer first, getting to know the nuances of what code is all about.

• flashlog viewer

  - by user334091

  Hi all, I want to build an application using air. The application should load the flashlog file and display the contents after performing some text filtering. But when i load the application this clears my flashlog.txt though my file mode is READ. I can understand that running my air application clears the flashlog and prepares it for new logging. Is there a workaround for this. I dont want to open the flashlog file everytime and check for traces from my web application

• Suppress errors of files that are not set to be built from the "Error List" window

  - by ohadsc

  I have some cs files in my project that are not set to be built (Properties - Build Action = None). They contain bits of code that don't compile as a whole and are there merely for reference. I don't care about any compilation errors in them, but they appear in the "Error List" window, cluttering it. Is there some way to tell VS to ignore errors in that file? Or in all files not set to be built, at that ? I'm using VS 2010 Thanks

• Java/Eclipse Dependency mapping / graphing tool - Where is a JAR being used in my project?

  - by gav

  Hi All, I have a JAR on the build path of a medium sized Java application and I would like to know where it's used. At the most basic level if someone could tell me how to 'Find References' for a Jar that would be great. Whilst I'm looking at dependencies it would be great to find a tool that would map all of my package / external library usages and graph them. I used to have a free plug-in for eclipse that did just that but I haven't been able to rediscover it. Thanks, Gav

  - by lampshade

  I made a post earlier but the information I got was wrong. How can I add two seperate objects? given that a, b and c are class objects of A, B and C then a = b + c, should invoke the operator+ overloaded operator. But lets say that I need to access private members to add the data.

• Are there any programmable barcode scanners that can call a webservice?

  - by Mark Redman

  I am looking at integrating a C# application with a barcode scanner. The last time I did this was with Delphi 1 (win 3.11) using a scanner that plugged in-line into the keyboard cable. Looking around it appears most scanners are USB based these days and assume they emulate keyboard entry. Anybody know of more sophisticated/programmable scanner that can call a webservice or even just do a basic POST/GET this would eliminate the C# application and the computer to support it?

• Is it possible to do a #define in Adobe Flex?

  - by Without me Its just Aweso

  I'm looking for a way to do something similar to a c/c++ #define in adobe flex. I'd like to have lots of different paths a project build can take depending on wither or not something was defined. Does such a thing exist in flex? I know there is ways to set global variables but that wont really suit my purpose. being able to have structures with numerous #ifndefined and such is really what i'm in need of. thanks!

• What to have in mind when building a AJAX-based webapp

  - by Industrial

  Hi everyone, We're in the first steps of what will be a AJAX-based webapp where information and generated HTML will be sent backwards and forwards with the help of JSON/POST techniques. We're able to get the data out quickly without putting to much load on the database with the help of a cache-layer that features memcached as well as disc-based cache. Besides that - what's essential to have in mind when designing AJAX heavy webapps? Thanks a lot,

• Evil merges in git - where do they come from?

  - by Benjol

  I've read this question and the answers, but what isn't clear to me is WHO creates the "changes that do not appear in any parent". Is it the git merge algorithm screwing up? Or is it because the user has to manually adjust the conflicts to get the thing to build, introducing new code which wasn't in either parent?

• Web Services with Android - why no support for WSDL ?

  - by Itsik

  I'm creating a Client/Server application with Android (Client) and WCF (Web Service). From reading quite alot of discussions, I'm under the impression that there is no tool available to create the web service client in android automatically from a WSDL file. If this is the situation, what is the easiest approach for creating a communication infrastructure between the client and server, that can be updated easily in the future (plain GET, REST, use SOAP and manually parse responses) Initially, I wanted to build the web service and have the client created automatically with the provided WSDL file. Thanks

• loading method based on URL

  - by steeped

  I am trying to build a small mvc-based application. How do I call a method in a class based on a query string? For example, the $_GET query string is being set as load_master_form http://www.domain.com/settings/load_master_form And to call the method within the settings class, I am doing: function __construct(){ $this->{$_GET['method']}(); } But obviously that doesn't work - it just isn't possible to load a method like that. So how would it be done?

• Javascript plugins design pattern like jQuery

  - by Marco Demaio

  Could someone write down a very simple basic example in javascript to conceptualize (and hopefully make me understand) how the jQuery plugin design pattern is done and how it works? I'm not interested in how creating plugin for jQuery (so no jQuery code here at all). I'm interested in a simple explanation (maybe with a bit of Javascript code) to explain how it is done the plugin concept. Plz do not reply me to go and read jQuery code, I tried, but I it's too complex, otherwise I would have not post a question here.

• WiX - Gotchas for Combining COM and .NET components in the same installer

  - by cmsjr

  I have two products that are always installed in tandem. One is an ActiveX exe the other a C# application. I've gotten the ActiveX installer to build and function properly using WiX and I'd really like to combine both into a single installer. I'm feeling just about dangerous enough with WiX to attempt it, but would be interested in any advice (particularly if it is inadvisable).
