  • Importing VMware drive into VirtualBox drive

    - by Bry4n
    I have VMware on my Mac and it crashed. I am unable to access the files used by the VMware. So I downloaded VirtualBox and when I try to add the .vmwarevm file to VirtualBox it says that its unable to read that type. I wasn't sure if there was a way i can get to these files as they are extremely important. I can not shutdown or open my virtual state in VMware whatsoever. Thoughts?

  • OpenGL, how to set a monochrome texture to a colored shape?

    - by Santiago
    I'm developing on Android with OpenGL ES, I draw some cubes and I change its colors with glColor4f. Now, what I want is to give a more realistic effect on the cubes, so I create a monochromatic 8bit depth, 64x64 pixel size PNG file. I loaded on a texture, and here is my problem, witch is the way to combine the color and the texture to get a colorized and textured cubes onto the screen? I'm not an expert on OpenGL, I tried this: On create: public void asignBitmap(GL10 gl, Bitmap bitmap) { int[] textures = new int[1]; gl.glGenTextures(1, textures, 0); mTexture = textures[0]; gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexture); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glTexEnvf(GL10.GL_TEXTURE_ENV, GL10.GL_TEXTURE_ENV_MODE, GL10.GL_REPLACE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_ALPHA, bitmap, 0); ByteBuffer tbb = ByteBuffer.allocateDirect(texCoords.length * 4); tbb.order(ByteOrder.nativeOrder()); mTexBuffer = tbb.asFloatBuffer(); for (int i = 0; i < 48; i++) mTexBuffer.put(texCoords[i]); mTexBuffer.position(0); } And OnDraw: public void draw(GL10 gl, int alphawires) { gl.glColor4f(1.0f, 0.0f, 0.0f, 0.5f); //RED gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexture); gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); gl.glEnable(GL10.GL_TEXTURE_2D); gl.glEnable(GL10.GL_BLEND); gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, mTexBuffer); //Set the face rotation gl.glFrontFace(GL10.GL_CW); //Point to our buffers gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer); //Enable the vertex and color state gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); //Draw the vertices as triangles, based on the Index Buffer information gl.glDrawElements(GL10.GL_TRIANGLES, 36, GL10.GL_UNSIGNED_BYTE, indexBuffer); //Disable the client state before leaving gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glDisable(GL10.GL_BLEND); gl.glDisable(GL10.GL_TEXTURE_2D); } I'm even not sure if I have to use a blend option, because I don't need transparency, but is a plus :)

  • Replace conditional with polymorphism refactoring or similar?

    - by Anders Svensson
    Hi, I have tried to ask a variant of this question before. I got some helpful answers, but still nothing that felt quite right to me. It seems to me this shouldn't really be that hard a nut to crack, but I'm not able to find an elegant simple solution. (Here's my previous post, but please try to look at the problem stated here as procedural code first so as not to be influenced by the earlier explanation which seemed to lead to very complicated solutions: http://stackoverflow.com/questions/2772858/design-pattern-for-cost-calculator-app ) Basically, the problem is to create a calculator for hours needed for projects that can contain a number of services. In this case "writing" and "analysis". The hours are calculated differently for the different services: writing is calculated by multiplying a "per product" hour rate with the number of products, and the more products are included in the project, the lower the hour rate is, but the total number of hours is accumulated progressively (i.e. for a medium-sized project you take both the small range pricing and then add the medium range pricing up to the number of actual products). Whereas for analysis it's much simpler, it is just a bulk rate for each size range. How would you be able to refactor this into an elegant and preferably simple object-oriented version (please note that I would never write it like this in a purely procedural manner, this is just to show the problem in another way succinctly). I have been thinking in terms of factory, strategy and decorator patterns, but can't get any to work well. (I read Head First Design Patterns a while back, and both the decorator and factory patterns described have some similarities to this problem, but I have trouble seeing them as good solutions as stated there. The decorator example seems very complicated for just adding condiments, but maybe it could work better here, I don't know. And the factory pattern example with the pizza factory...well it just seems to create such a ridiculous explosion of classes, at least in their example. I have found good use for factory patterns before, but I can't see how I could use it here without getting a really complicated set of classes) The main goal would be to only have to change in one place (loose coupling etc) if I were to add a new parameter (say another size, like XSMALL, and/or another service, like "Administration"). Here's the procedural code example: public class Conditional { private int _numberOfManuals; private string _serviceType; private const int SMALL = 2; private const int MEDIUM = 8; public int GetHours() { if (_numberOfManuals <= SMALL) { if (_serviceType == "writing") return 30 * _numberOfManuals; if (_serviceType == "analysis") return 10; } else if (_numberOfManuals <= MEDIUM) { if (_serviceType == "writing") return (SMALL * 30) + (20 * _numberOfManuals - SMALL); if (_serviceType == "analysis") return 20; } else //i.e. LARGE { if (_serviceType == "writing") return (SMALL * 30) + (20 * (MEDIUM - SMALL)) + (10 * _numberOfManuals - MEDIUM); if (_serviceType == "analysis") return 30; } return 0; //Just a default fallback for this contrived example } } All replies are appreciated! I hope someone has a really elegant solution to this problem that I actually thought from the beginning would be really simple... Regards, Anders

  • What tricks do you use to get yourself "in the zone"?

    - by Tim Jarvis
    Once I am "in the zone" I am extremely productive and code just flows out of me, often I can get 2 or 3 days coding done in 1 day. But I find that often its hard to get to that place, I find myself procrastinating, getting distracted by other things (SO for example). Is this experience common? How do you force yourself into that state of mind? Is it simply something you can't force?

  • Will this static class break in a multi user scenario ?

    - by Perpetualcoder
    Say I make a static class like following with an extension method: public static class MyStaticExtensionClass { private static readonly Dictionary<int, SomeClass> AlgoMgmtDict = new Dictionary<int, SomeClass>(); public static OutputClass ToOutput(this InputClass input) { // clears up the dict // does some kind of transform over the input class // return an OutputClass object } } In a multi user system, will the state management dictionary fail to provide correct values for the transform algorithm? Will a regular class be a better design or shoving the Dictionary inside the method a better design?

  • Automaticly Change VisualState in Silverlight

    - by Matt
    If you create a simple button and then choose Edit Template - Edit a Copy, Blend will automatically generate a style area, along with all the button states (MouseEnter, MouseLeave, Pressed, etc). No where in the generated code does it say that on a "MouseOver" event, change the state to "MouseOver", but it still manages to work! How does a standard button do it? Is there some sort of AutoEventWireUp going on?

  • how to remove empty tags in input xml

    - by SGB
    My java module gets a huge input xml from a mainframe. Unfortunately, the mainframe is unable to skip optional elements when it is not a leaf node, with the result that I get a LOT of empty tags in my input : So, <pre><code><SSN>111111111</SSN> <Employment> <Current> <Address> <line1/> <line2/> <line3/> <city/> <state/> <country/> </Address> <Phone> <phonenumber/> <countryCode/> </Phone> </Current> <Previous> <Address> <line1/> <line2/> <line3/> <city/> <state/> <country/> </Address> <Phone> <phonenumber/> <countryCode/> </Phone> </Previous> </Employment> <MaritalStatus>Single</MaritalStatus> </code></pre> should be <SSN>111111111</SSN> <MaritalStatus>Single</MaritalStatus> I use jaxb to unmarshall the input xml string that the mainframe sends it. Is there a clean/ easy way to remove all the empty group tags, or do I have to do this manuall in the code for each element. I have over 35 elements in my input xml, so I would love to it if jaxb itself had a way of doing this automatically? Thanks, SGB

  • Why can I not access this class member in python?

    - by Peter Smit
    I have the following code class Transcription(object): WORD = 0 PHONE = 1 STATE = 2 def __init__(self): self.transcriptions = [] def align_transcription(self,model,target=Transcription.PHONE): pass The important part here is that I would like to have a class member as default value for a variable. This however gives the following error: NameError: name 'Transcription' is not defined Why is this not possible and what is the right (pythonic) way to do something like this.

  • WPF MVVM Cancel Edit

    - by terkri
    How can I implement cancelation of editing an object using MVVM. For example: I have a list of customers. I choose one customer an click the button "Edit", a dialog window(DataContext is binded to CustomerViewModel) opens and I start editing customer's fields. And then I decide to cancel editing, but the fields of the customer have been already changed, so how can I return a customer to its previous state in MVVM?

  • best way to record local modifications to an application's configuration files

    - by Menelaos Perdikeas
    I often install applications in Linux which don't come in package form but rather one just downloads a tarball, unpacks it, and runs the app out of the exploded folder. To adjust the application to my environment I need to modify the default configuration files, perhaps add an odd script of my own and I would like to have a way to record all these modifications automatically so I can apply them to another environment. Clearly, the modifications can not be reproduced verbatim as things like IP addresses or username need to change from system to system; still an exhaustive record to what was changed and added would be useful. My solution is to use a pattern involving git. Basically after I explode the tarball I do a git init and an initial commit and then I can save to a file the output of git diff and a cat of all files appearing as new in the git status -s. But I am sure there are more efficient ways. ???

  • How to search a text file for strings between two tokens in Ubuntu terminal and save the output?

    - by Blue
    How can I search a text file for this pattern in Ubuntu terminal and save the output as a text file? I'm looking for everything between the string "abc" and the string "cde" in a long list of data. For example: blah blah abc fkdljgn cde blah blah blah blah blah blah abc skdjfn cde blah In the example above I would be looking for an output such as this: fkdljgn skdjfn It is important that I can also save the data output as a text file. Can I use grep or agrep and if so, what is the format?

  • Visual Studio 2010 Graphic Artifacts

    - by jonathan
    This problem started happening to me once I installed SP1 onto my Windows 7 Ultimate install. When changing between tabs, or even just hovering my mouse over buttons, VS2010 starts artifacting. It's bad enough where I often times can't see any of the code I'm working on. Sometimes just the button the mouse is over will go black, and other times the entire code panel will turn a black and grey pattern. This problem only happens with Visual Studio 2010 (2008 works fine). The problem remained when I upgraded Visual Studio to SP1. I've also uninstalled and reinstalled Visual Studio and the graphics drivers several times now, and I'm about ready to reinstall Windows 7, but I figured I'd ask for suggestions first. Google, as well as searching through Stack Exchange, did not turn up anything useful.

  • Ternary operator in if-statement?

    - by Pindatjuh
    I've written the following if-statement in Java: if(methodName.equals("set" + this.name) || isBoolean() ? methodName.equals("is" + this.name) : methodName.equals("get" + this.name)) { ... } Is this a good practice to write such expressions in if, to separate state from condition? And can this expression be simplified?

  • Where does INumeric come from?

    - by jdk
    I see kudos to INumeric and blog posts that state how to simulate the features in its absence from a language (e.g. this post ) But in what language/s does this INumeric goodness originate from? In other words in what languages would I find examples of INumeric? I Googled its name and didn't come up with useful results about origin or examples. But I'm sure somebody here knows...

  • Does CakePHP treat all INT fields as ID's for join tables?

    - by Jonnie
    I am trying to save a User, their Profile, and some tags and my join table that links the profile and the tags keeps getting messed up. The profile model is called Instructor, the tag model is called Subject. The Instructor has a phone number and a zip code and for some reason CakePHP thinks these are the fields it should use when creating entries in my join table. My Join table always comes out as: id | instructor_id | subject_id | 1 | 90210 | 1 | // thinks that the zip code is an instructor_id 2 | 1112223333 | 1 | // thinks that the phone number is an instructor_id 3 | 1 | 1 | // thinks that user_id is an instructor_id 4 | 1 | 1 | // the actual instructor_id, this one's correct 5 | 90210 | 2 | 6 | 1112223333 | 2 | 3 | 1 | 2 | 4 | 1 | 2 | My Models: class Instructor extends AppModel { var $name = 'Instructor'; var $belongsTo = array('User', 'State'); var $hasAndBelongsToMany = array( 'Subject' = array( 'className' = 'Subject', 'joinTable' = 'instructors_subjects', 'foreignKey' = 'instructor_id', 'associationForeignKey' = 'subject_id', 'unique' = true, 'conditions' = '', 'fields' = '', 'order' = '', 'limit' = '', 'offset' = '', 'finderQuery' = '', 'deleteQuery' = '', 'insertQuery' = '' ) ); } class Subject extends AppModel { var $name = 'Subject'; var $hasAndBelongsToMany = array( 'Instructor' = array( 'className' = 'Instructor', 'joinTable' = 'instructors_subjects', 'foreignKey' = 'subject_id', 'associationForeignKey' = 'instructor_id', 'unique' = true, 'conditions' = '', 'fields' = '', 'order' = '', 'limit' = '', 'offset' = '', 'finderQuery' = '', 'deleteQuery' = '', 'insertQuery' = '' ) ); } My Model Associations: User hasOne Instructor Instructor belongsTo User Instructor hasAndBelongsToMany Subject Subject hasAndBelongsToMany Instructor My form data looks like: Array ( [User] = Array ( [username] = MrInstructor [password] = cddb06c93c72f34eb9408610529a34645c29c55d [group_id] = 2 ) [Instructor] = Array ( [name] = Jimmy Bob [email] = [email protected] [phone] = 1112223333 [city] = Beverly Hills [zip_code] = 90210 [states] = 5 [website] = www.jimmybobbaseballschool.com [description] = Jimmy Bob is an instructor. [user_id] = 1 [id] = 1 ) [Subject] = Array ( [name] = hitting, pitching ) ) My function for processing the form looks like: function instructor_register() { $this-set('groups', $this-User-Group-find('list')); $this-set('states', $this-User-Instructor-State-find('list')); if (!empty($this-data)) { // Set the group to Instructor $this-data['User']['group_id'] = 2; // Save the user data $user = $this-User-save($this-data, true, array( 'username', 'password', 'group_id' )); // If the user was saved, save the instructor's info if (!empty($user)) { $this-data['Instructor']['user_id'] = $this-User-id; $instructor = $this-User-Instructor-save($this-data, true, array( 'user_id', 'name', 'email', 'phone', 'city', 'zip_code', 'state_id', 'website', 'description' )); // If the instructor was saved, save the rest if(!empty($instructor)) { $instructorId = $this-User-Instructor-id; $this-data['Instructor']['id'] = $instructorId; // Save each subject seperately $subjects = explode(",", $this-data['Subject']['name']); foreach ($subjects as $_subject) { // Get the correct subject format $_subject = strtolower(trim($_subject)); $this-User-Instructor-Subject-create($this-data); $this-User-Instructor-Subject-set(array( 'name' = $_subject )); $this-User-Instructor-Subject-save(); echo ''; print_r($this-data); echo ''; } } } } }

  • SQLite DB borked when opened on a different machine

    - by pruefsumme
    Hello, I'm using SQLite to store some data. The primary database is on a NAS (Debian Lenny, 2.6.15, armv4l) since the NAS runs a script which updates the data every day. A typical "select * from tableX" looks like this: 2010-12-28|20|62.09|25170.0 2010-12-28|21|49.28|23305.7 2010-12-28|22|48.51|22051.1 2010-12-28|23|47.17|21809.9 When I copy the DB to my main computer (Mac OS X) and run the same SQL query, the output is: 2010-12-28|20|1.08115035175016e-160|25170.0 2010-12-28|21|2.39343503830763e-259|-9.25596535779558e+61 2010-12-28|22|-1.02951149572792e-86|1.90359837597183e+185 2010-12-28|23|-1.10707273937033e-234|-2.35343828462275e-185 The 3rd and 4th column have the type REAL. Interesting fact: When the numbers are integer (i.e. they end with ".0"), there is no difference between the two databases. In all other cases, the differences are ... hm ... surprising? I can't seem to find a pattern. If someone's got a clue - please share!
