  • Need some help understanding this problem

    - by Legend
    I was wondering if someone could help me understand this problem. I prepared a small diagram because it is much easier to explain it visually. Problem I am trying to solve: 1. Constructing the dependency graph Given the connectivity of the graph and a metric that determines how well a node depends on the other, order the dependencies. For instance, I could put in a few rules saying that node 3 depends on node 4 node 2 depends on node 3 node 3 depends on node 5 But because the final rule is not "valuable" (again based on the same metric), I will not add the rule to my system. 2. Execute the request order Once I built a dependency graph, execute the list in an order that maximizes the final connectivity. First and foremost, I am wondering if I constructed the problem correctly and if I should be aware of any corner cases. Secondly, is there a closely related algorithm that I can look at? Currently, I am thinking of something like Feedback Arc Set or the Secretary Problem but I am a little confused at the moment. Any suggestions? PS: I am a little confused about the problem myself so please don't flame on me for that. If any clarifications are needed, I will try to update the question.

  • How extension methods work in background ?

    - by Freshblood
    I am just cuirous about behind of extension method mechanism.Some questions and answer appear in my mind. MyClass.OrderBy(x=>x.a).OrderBy(x=>x.b); I was guessing that mechanism was first orderby method works and order them by a member then returns sorted items in IEnumarable interface then next Orderby method of IEnumarable Order them for b paramater.But i am wrong when i look at this linq query. MyClass.Orderby(x=>x.a).ThenOrderBy(x=>x.b); this is slightly different and tells me that i am wrong.Because this is not ordering by a then b and not possible to have such result if i was right.This get me confuse enough... Similiar structure is possible to write withot extension methods as first query but second is not possible.This prove i am wrong . Can u explain it ?

  • Can GraphViz be used for a graph editing GUI?

    - by user185420
    I am creating an application which will allow a developer to create a program flow-chart by selecting pre-defined functions from a ToolBox (which will show up as small graphical elements). In other words, developer will select one or more pre-defined functions (graphical elements) from ToolBox and drag-drop on the main work area. The application will then, based on the flow of functions selected, will auto-generate ready-to-compile-code. I looked a GraphViz, but am not sure whether it can be used to create a GUI IDE for editing graphical elements. I am looking for a functionality similart to Microsoft Visio, where users can add/remove/drag-drop/ various shapes to create a diagram. Does GraphViz fit in here? If yes, can you direct me to some examples showing how to do it? If GraphViz cannot be used, what are the other open source/free components available? I am intending to build the final application in .Net.

  • Ignoring a character along with word boundary in regex

    - by DavidP6
    I am using gsub in Ruby to make a word within text bold. I am using a word boundary so as to not make letters within other words bold, but am finding that this ignores words that have a quote after them. For example: text.gsub(/#{word}\b/i, "<b>#{word}</b>") text = "I said, 'look out below'" word = below In this case the word below is not made bold. Is there any way to ignore certain characters along with a word boundary?

  • py2app generates .app with no errors but .app crashes and quits unexpectedly

    - by user3705730
    I am trying to use py2app and it generates .app with no errors but .app crashes and quits unexpectedly. I am trying to do this in virtualenv so I am not sure if that is an issue with all the paths. It works on my computer when all the virtual environments exist but as soon as I close them down, the .app no longer works. The virtual environment I am using has python 2.7.5 Here is my setup.py: """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['myApp.py'] DATA_FILES = [] OPTIONS = {'argv_emulation': True, 'packages': ['pulp']} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], )

  • How to use Map element as text of a JComboBox

    - by llm
    I am populating a JComboBox (using addItem()) with all the elements of a collection. Each element in the collection is a HashMap (so its a ComboBox of Hashmaps..). My question is - Given that I need each item to be a HashMap how do I set the text to apear in the combobox on the GUI? It needs to be the value of a certain key in the map. Normally if I am populating a combobox with my own type, I would just overide the toString() method...but I am not sure how to acheive this since I am using a Java HashMap. Any ideas (if possible, without implementing my own HashMap)? Update: It seems like there isn't anyway to avoid having the object int the JComboBox overide toString() if I want custom functionality..I wish there was a way to (1) specify the objects to be loaded into the JComboBox and (2) specify how these objects are to appear in the GUI.

  • PHP Sessions and Passing Session ID

    - by Jason McCreary
    I have an API where I am passing the session id back and forth between calls. I set up the session like so: // start API session session_name('apikey'); session_id($data['apikey']); // required to link session session_start(); Although I named my session and am passing the session id via GET and POST using the name, PHP does not automatically resume that session. It always creates a new one unless I set the explicitly set the session id. I found some old user comments on www.php.net that said unless the session id is the first parameter PHP won't set it automatically. This seems odd, but even when I call tried it still didn't work: rest_services.php?apikey=sdr6d3subaofcav53cpf71j4v3&q=testing I have used PHP for years, but am a little confused on why I needed to explicitly set the session with session_id() when I am naming the session and passing it's key accordingly. UPDATE It seems I wasn't clear. My question is why is setting the session ID with session_id() required when I am passing the id, using the session name apikey, via $_GET or $_POST. Theoretically this is no different than PHP's SID when cookies are disabled. But for me it doesn't work unless I explicitly set the session ID. Why?

  • How to load an image in matlab from java

    - by Ian
    Basically I am trying to create a little program that will allow me to make calls in matlab from a jave GUI It's mainly going to be used for image manipulation and deblurring but I am struggling to find a way that will effectively give me full matlab control from the java end I am hoping to have it work like so: { //create matlab execution call String loadImage = " image1 = imread ('imageOnComputer.jpg'); "; //send instruction to matlab and save the path to it so java can //use the newly created variable resultingVariablePath = java.sendInstructionToMatlab(loadImage); //display on the screen java.displayImage(resultingVariablePath); } Basically I am just trying to find out if there is a plugin for matlab (or some java package) that will grant you (pretty much) full control over matlab.

  • What is the best answer to give for, "Why do you want to change from your present organization?"

    - by Techmaddy
    At present I am into a very good organization. I am planning to shift because I am not happy with the work that I am getting now. I want to work under a different Manager, but my Manager and team is more dependent on me. I tried so many times, but couldn't change my team. So, I started planning to switch my company. Everyone is asking the same question, "Why do you want to change?". Should I say the truth? I told this in 2 places, but did not see a good response from them. Or is there a better answer that I can give?

  • Setting the origin to center of the screen instead of the top left screen?(iPhone)

    - by thyrgle
    Hi, I am working on an iPhone app and I am trying to make something that has to do with line-circle collision detection. I am using the slope of the line and checking if the coordinates of a circle suffice the equation y = mx + b. But, with the current origin (0,0) at the top left it is a pain to get the slope. Any way I can convert the coordinates so the origin is in the center of the screen?

  • GWT-RPC vs HTTP Call - which is better??

    - by Nirmal Patel
    I am evaluating if there is a performance variation between calls made using GWT-RPC and HTTP Call. My appln services are hosted as Java servlets and I am currently using HTTPProxy connections to fetch data from them. I am looking to convert them to GWT-RPC calls if that brings in performance improvement. I would like to know about pros/cons of each... Also any suggestions on tools to measure performance of Async calls...

  • Problems debugging using Cygwin gdb in Eclipse CDT(Helios)

    - by Rohan
    I am trying to debug an application using Eclipse CDT and cygwin gdb and I am facing a problem if my code calls Sleep(), it looks like whenever a sleep is encountered in the code the debugger seems to go in an infinite loop(I meant it never terminates or hit a breakpoint after sleep). On pressing pause the code is stuck on one of the thread on sigint::interrupt. Even my debugger console windows throw these error in the console output: [New thread 5968.0x1f98] Error: dll starting at 0x774a0000 not found. Error: dll starting at 0x775c0000 not found. [New thread 5968.0x19e8] Any idea what are these errors about? It would be helpful if someone can help me out here as I am new to eclipse and I am used to using VS so it has made be lazy to be honest and expect things to work out of box. Here are more details if required Windows 7 x64 bit. Eclipse 3.6 Helios with CDT plug-in compiled from the CVS head. Cygwin latest from website, I think it is 1.71

  • Manipulating individual rows of a datagrid

    - by pfranchise
    Hey, recently I started working on a webpage that has a datagrid. I understand how to add datasources and that sort of thing, or at least I am starting to get it. But my question is about manipulating individual rows or cells. Is that only possible during the databind event handler, that is the only place I have been able to do it so far. I am sure there is a more abstract way of doing the things I want to do, but there are times where I just want to say Datagrid.add(row). I mean, if the datagrid is made up of a certain object type, can I make a new object of that type and just chuck it on the end? I am still new to this stuff, so perhaps what I want to do would defeat the purpose of this added abstraction, but figured I would ask around. Thanks for any advice, tips, or tricks people feel like sharing. Edit: for clarification I am using c#, entity framework, asp.net, and an SQL database.

  • mocking command object in grails controller results in hasErrors() return false no matter what! Plea

    - by egervari
    I have a controller that uses a command object in a controller action. When mocking this command object in a grails' controller unit test, the hasErrors() method always returns false, even when I am purposefully violating its constraints. def save = { RegistrationForm form -> if(form.hasErrors()) { // code block never gets executed } else { // code block always gets executed } } In the test itself, I do this: mockCommandObject(RegistrationForm) def form = new RegistrationForm(emailAddress: "ken.bad@gmail", password: "secret", confirmPassword: "wrong") controller.save(form) I am purposefully giving it a bad email address, and I am making sure the password and the confirmPassword properties are different. In this case, hasErrors() should return true... but it doesn't. I don't know how my testing can be any where reliable if such a basic thing does not work :/ Here is the RegistrationForm class, so you can see the constraints I am using: class RegistrationForm { def springSecurityService String emailAddress String password String confirmPassword String getEncryptedPassword() { springSecurityService.encodePassword(password) } static constraints = { emailAddress(blank: false, email: true) password(blank: false, minSize:4, maxSize: 10) confirmPassword(blank: false, validator: { confirmPassword, form -> confirmPassword == form.password }) } }
