  • how to store assembly in memory

    - by da cheng
    Hi, I have a question about how to store the assembly language in memory,when I compile the C-code in assembly, and run by "step", I can see the address of each instruction, but is there a way to change the start address of the code in the memory? Second question is, can I break the assembly code into two? I am curious about how the machine store the assembly code. BTW, I am working on a MACBOOK Pro, duo core. Thank you. -da

  • Is Android a product line?

    - by geowa4
    Android is an open source operating system that is modified by cell phone vendors (HTC, Motorola, etc.). Modifications include the user interface, drivers, and other proprietary extensions. Traditionally, product lines have been a suite of products or services that share a core set of functionality and are modified for different domains and markets. Does this still qualify as a product line?

    - by Nano8Blazex
    Another newbie question: What's the best way to store data in a Cocoa application written in Obj-C? For example if I want to create a sort of "quizzer" that quizzes the user with pre-written (and user-written) questions? How would I store these questions and answers? Core Data? Thanks!

  • What version of mongodb was full $text query operator introduced?

    - by Marc Maxson
    Stupid question, right? But the official docs for 'text index' say: http://docs.mongodb.org/manual/core/index-text/ Text Indexes New in version 2.4. To perform queries that access the text index, use the $text query operator. Whereas if you click on the help for searching the index you created with the $text operator, it reads: http://docs.mongodb.org/manual/reference/operator/query/text/#op._S_text $text New in version 2.6. Seems to be 2.4 but still having problems wiht it.

  • Is it possible to build exe on Vista and deploy on XP using py2exe

    - by dfens
    I have created some program using python on Windows Vista. But I want to deploy it on Windows XP. Is it necessary to make new build on windows XP? Or there is possibility to make build that will work on both of these systems? EDIT (EDIT 2 - very simple program does not work also): My setup: from distutils.core import setup import py2exe setup(console=['orderer.py']) Using dependency explorer i checked that dependencies are: msvcr90.dll kernel32.dll +ntdll.dll

  • What's the best approach for readonly property

    - by Patrick Parent
    Hi, I'm using a model UserRepository-User The Repository is used to Save and Load the User. I want to be able to set the ID in the Repository, but I don't want it to be access by UI. The User and Repository are found in a Core project, and the UI in a Web. Is there a way to do this, like a modifier for the property, or should I put the ID in the User contructor ? Thanks

  • "reduce" or "apply" using logical functions in Clojure

    - by Alex B
    I cannot use logical functions on a range of booleans in Clojure (1.2). Neither of the following works due to logical functions being macros: (reduce and [... sequence of bools ...]) (apply or [... sequence of bools ...]) The error saying that I "can't take value of a macro: #'clojure.core/and". How to apply these logical functions (macros) without writing boilerplate code?

  • Upgrading From EF 4x to 6 breaks everything

    - by dan h
    Attempted to upgrade my project from EF4 to EF6, I get build errors It appears that if i swap out the namespaces manually to include the entity.core it works, but if i change the .edmx file at all, the code reverts back to the old references and i have to manually edit the code generation files to include the update namespace references. I have attempted to "add code generation item" that does not resolve the issue at all. When i open the .edmx file in the IDE it shows me everything correctly.

  • How to detect .NET WPF memory leak or GC long run?

    - by Néstor Sánchez A.
    I have the next very strange situation and problem: .NET 4.0 application for diagram editing (WPF). Runs ok in my PC: 8GM RAM, 3.0GHz, i7 quad-core. While creating objects (mostly diagram nodes and connectors, plus all the undo/redo information) the TaskManager show, as expected, some memory usage "jumps" (up and down). These mem-usage "jumps" also remains executing AFTER user interaction ended. Maybe this is the GC cleaning/regorganizing memory? To see what is going on, I've used the Ants mem profiler, but somewhat it prevents those "jumps" to happen after user interaction. PROBLEM: It Freezes/Hangs after seconds or minutes of usage in some slow/weak laptos/netbooks of my beta testers (under 2GHz of speed and under 2GB of RAM). I was thinking of a memory leak, but... EDIT: Also, there is the case that the memory usage grows and grows until collapse (only in slow machines). In a Windows XP Mode machine (VM in Win 7) with only 512MB of RAM Assigned it works fine without mem-usage "jumps" after user interaction (no GC cleaning?!). So, I really have a big trouble because I cannot reproduce the error, only see these strange behaviour (mem jumps), and the tool supposed to show me what is happening is hiding the problem (like the "observer's paradox"). Any ideas on what's happening and how to solve it?

  • Passing Request Object into Service Layer

    - by SpringTrickery
    In a spring mvc + spring core app, we have have a view layers, a facade, a service layer, a dao layer and a stored-proc based persistance layer. The service layer is unaware of the clients that utilitize its methods. Is it fine to propagate raw http requests into the service layer? Or is it bad practice and a violation of the loose coupling principles? If it is, then what's a clean workaround?

  • Object disapear/don't scale in the Z-AXIS of OPENGL.

    - by user315684
    This code is susposed to have a QUAD orbit around a center point in basically a circle. The problem is while it does the X rotation fine it disapears when it moves in Z axis and doesn't appear to change in size. It feel like it's rendering everything in Orthagraphic view or something. This is my first OpenGL project. OPENGL CODE START HERE glClearColor(0.0f, 0.0f, 0.0f, 0.0f); glClear(GL_COLOR_BUFFER_BIT); glMatrixMode (GL_PROJECTION); glPushMatrix(); //glRotatef(theta, 0.0f, 0.0f, 1.0f); glScalef(0.75f, 0.75f, 0.75f); glTranslatef(planeX, -0.0f, 0.0f); glBegin(GL_QUADS); glColor3f(1.0f, 0.0f, 0.0f); glVertex3f(0.0f, 0.0f, planeZ); glColor3f(0.0f, 1.0f, 0.0f); glVertex3f(0.0f, 1.0f, planeZ); glColor3f(0.0f, 0.0f, 1.0f); glVertex3f(1.0f, 1.0f, planeZ); glColor3f(0.0f, 0.0f, 1.0f); glVertex3f(1.0f, 0.0f, planeZ); glEnd(); glPopMatrix(); SwapBuffers(hDC); theta += 1.0f; planeX = (sin(0.0314159265f*theta)); planeZ = (cos(0.0314159265f*theta)); Sleep (1); ENDS HERE

  • How to refactor logging in C#?

    - by Jader Dias
    In my services all exposed methods have: try { // the method core is written here } catch(Exception ex) { Log.Append(ex); } It's boring and ugly to repeat it over and over again. There is any way to avoid that? There is better way to keep the service working even if exceptions occurs and keep sending the exception details to the Log class?
