  • conversion of assembly

    hello, can somebody please explain is it possible to convert this snippet of the code to assembly of pdp11? movq %rdi, -8(%rbp) movl %esi, -12(%rbp) movl %edx, -16(%rbp) movl -16(%rbp), %eax cltq leaq 0(,%rax,4), %rdi movq -8(%rbp), %r8 movl -12(%rbp), %eax cltq leaq 0(,%rax,4), %rcx movq -8(%rbp), %rsi movl -16(%rbp), %eax cltq leaq 0(,%rax,4), %rdx movq -8(%rbp), %rax movl (%rdx,%rax), %eax addl (%rcx,%rsi), %eax movl %eax, (%rdi,%r8) movl -12(%rbp), %eax cltq leaq 0(,%rax,4), %rdi movq -8(%rbp), %r8 movl -16(%rbp), %eax cltq leaq 0(,%rax,4), %rcx movq -8(%rbp), %rsi movl -12(%rbp), %eax cltq leaq 0(,%rax,4), %rdx movq -8(%rbp), %rax movl (%rdx,%rax), %edx movl (%rcx,%rsi), %eax subl %edx, %eax movl %eax, (%rdi,%r8) movl -16(%rbp), %eax cltq leaq 0(,%rax,4), %rdi movq -8(%rbp), %r8 movl -16(%rbp), %eax cltq leaq 0(,%rax,4), %rcx movq -8(%rbp), %rsi movl -12(%rbp), %eax cltq leaq 0(,%rax,4), %rdx movq -8(%rbp), %rax movl (%rdx,%rax), %edx movl (%rcx,%rsi), %eax subl %edx, %eax movl %eax, (%rdi,%r8) leave ret it is only small part of all code that I have...

  • How to use acts-as-commentable-with-threading in Rails

    - by alex
    Hi All, I am developing my first rails site (yup, i am a rails idiot). I'm writing a blog, and i got to the comments part. I installed acts-as-commentable-with-threading ( GitHub ), i made and ran the migration like the install instructions said. I have added acts_as_commentable to my Posts model and i have a Comments controller When i add @comment = Comment.build_from(params[:id],1, params[:body] ) I get the error. undefined method `build_from' for # Clearly i am doing something terribly wrong, and i don't really get the example. What should i be feeding to build_from? Can somebody explain this plugin step by step? :) Or is there an easier way to get simple threaded comments?

  • Building a clip area in a UIView from path objects in its subviews

    - by hkatz
    I'm trying to produce a clipping area in a UIView that's generated from path objects in its subviews. For example, I might have one subview containing a square and another containing a circle. I want to be able to produce a clip in the parent superview that's the union of both these shapes. Can someone explain how to do this? About all I've been able to figure out so far is that: 1 - the superview's drawRect: method is called before its subviews' drawRects are, and 2 - the ContextRef that's accessible in all three instances is the same. Other than that I'm stumped. Thanks, Howard

  • Sql Server Service Broker Conversation Groups

    - by Brian Hasden
    Can someone explain conversation groups in service broker? Currently, I'm using service broker to send messages from one SQL server to another. On the sending server, I'm trying to correlate the messages so they are processed in serial on the receiving side. Based on the documentation, conversation groups seem to be a perfect fit for this, but on the receiving server, the messages get assigned to a different conversation group from the one I specified when sending the message. I've search around the web and saw that this behavior seems to be intended (http://social.msdn.microsoft.com/forums/en-US/sqlservicebroker/thread/baf48074-6804-43ab-844a-cb28a6dce02b/), but then I'm confused about the usefulness of the syntax from (http://msdn.microsoft.com/en-us/library/ms178624.aspx) WAITFOR( GET CONVERSATION GROUP @conversation_group_id FROM [dbo].[ReceiveQueue] ) If the conversation group doesn't come across with the message from the sender and messages sent with the same conversation group id don't have the same conversation group id on the receive side, what's the point of the code above?

  • PopupWindow with GridView - Trouble with inflating view

    - by k_day
    I am having an issue while trying to use a GridView in a PopupWindow. On my Activity's onCreate method, I am inflating a gridview from xml as follows: LayoutInflater inflater = (LayoutInflater)this.getSystemService (Context.LAYOUT_INFLATER_SERVICE); final GridView popupview = (GridView) inflater.inflate (R.layout.gridviewpopup, null, false); popupview.setAdapter(new ImageAdapter(this)); would like this GridView to popup on a button click. Also inside of my activity's onCreate, I have: final Button addButton = (Button) findViewById(R.id.add); addButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { PopupWindow mwindow = new PopupWindow(popupview, 100, 100); mwindow.showAtLocation(findViewById(R.id.main), Gravity.CENTER, 100, 100); mwindow.setFocusable(true); } }); On button click, I am throwing a ClassCastException from GridView.onMeasure(int, int). Can anyone please explain to me what I am doing wrong?

  • 2D collision detection and stuff with OpenGL

    - by shinjuo
    I am working on a simple 2D openGL project. It contains a main actor you can control with the keyboard arrows. I got that to work okay. What I am wanting is something that can help explain how to make another actor object follow the main actor. Maybe a tutorial on openGL. The three main things I need to learn are the actor following, collision detection, and some kind of way to create gravity. Any good books or tutorials to help get me in the right direction would be great.

  • unwanted quote marks in output from printf

    - by Gary
    I have some address data which has been exported from a database. If the address had multiple lines, the exported data has joined all the lines into one string with the former lines being separated by dollars signs. Here's one of the addresses: INFORMATION DELIVERY DEPT$704 CHERRY ST$ATLANTA, GA 30332-0900 I'm splitting this into an array on the dollar sign and outputting the three array elements into separate tab-separated fields with printf. For some reason, it comes out like this: INFORMATION DELIVERY DEPT 704 CHERRY ST "ATLANTA, GA 30332-0900" I don't want the quotes around that final field. Can anyone explain why this is happening and how to suppress it? This is being done in Windows Vista with gawk3.1.6. Thanks! gary

  • How to use Cassandra's Map Reduce with or w/o Pig?

    - by UltimateBrent
    Can someone explain how MapReduce works with Cassandra .6? I've read through the word count example, but I don't quite follow what's happening on the Cassandra end vs. the "client" end. https://svn.apache.org/repos/asf/cassandra/trunk/contrib/word_count/ For instance, let's say I'm using Python and Pycassa, how would I load in a new map reduce function, and then call it? Does my map reduce function have to be java that's installed on the cassandra server? If so, how do I call it from Pycassa? There's also mention of Pig making this all easier, but I'm a complete Hadoop noob, so that didn't really help. Your answer can use Thrift or whatever, I just mentioned Pycassa to denote the client side. I'm just trying to understand the difference between what runs in the Cassandra cluster vs. the actual server making the requests.

  • Selectively configuring Apache 2 mod_headers for Google Chrome Frame

    - by Adam Cobb
    I am currently evaluating Google Chrome Frame and so far i'm happy with it, but what i'd like to do is selectively use it for certain sections of my website. Some sections require ActiveX so need to be viewed in native IE, whereas others benefit greatly, and may end up requiring, Chrome Frame. I've currently got the following configured in my apache httpd.conf file - <IfModule mod_setenvif.c> <IfModule mod_headers.c> BrowserMatch chromeframe gcf Header append X-UA-Compatible "chrome=1" env=gcf </IfModule> </IfModule> This causes anything coming in via Apache to get the chrome frame stuff added to the headers. What I need is to make this only happen when a user visits particular URL's / particular pages, which i'm currently controlling via RewriteRules. Could anybody explain how I would go about this, as my understanding of the Apache config files isn't brilliant. Thanks.

  • How do I run different threads in Java?

    - by Cris Carter
    Hey. I'm having some problems with threads. I understand how they work, but since they all use the same method, how do I run different threads that do completely different things, but at the same time? To me, it seems that they always use the same standard method which makes them do the same thing. So, let's say I have a big .txt file where I want to go through each line and do something to the line. In this case, I would like to have each thread do 1/10th of the .txt file, but I don't understand how the threads can communicate with each other, and how they could organize so each thread does the right part? Could anyone explain or help me with this? Would be very much appreciated!

  • How do I make the "change order" button appear in SharePoint 2010?

    - by Jan Aagaard
    How do I make the "change order" button appear in SharePoint 2010? I have followed a guide that allowed me to add OrderedList="TRUE" to my list template. This makes it possible to select "Allow users to order items in this view" for my view. But the change order button is still missing. Any idears on what I am missing? I am using SharePoint 2010 and the guide is from 2006, so that might explain why it doesn't just work. The guide from tech-archive.net.

  • Problem with persisting inteface collection at design time in winforms, .net

    - by Jules
    The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?

  • How to implement SCORM in Objective C

    - by iranjan
    Hey, Do you know how to implement SCORM (Sharable Content Object Reference Model) in Objective C for eLearning content? Let me explain you what exactly I am looking for. I have one MCQ (multiple choice question) application which has 4 questions. On attempting each question I want my application to interact with a SCORM compatible server with result (whether the user has attempted correct one or not). The communication channel should be to and fro. May be at the end of the MCQ I want to show result which will come from the server with some calculations*(like Score : 85% number of attempts : 16 average score:16.7% etc.)*. How should I go about it? Please guide if you have already achieved it regards Ranjan.

  • c# peer-to-peer networking - getting around routers

    - by The.Anti.9
    I want to code a peer-to-peer like chat program in C#. I am trying to figure out how the networking would work. I know that the concept is that each peer is a client and a server at the same time. It can connect and be connected to. But my question is, how do you connect to a computer behind a router without the port being forwarded to that computer? I know things like Bittorrent do this with no problem. I was planning on using a tracker to keep a list of peers and the ports they listen on, but I still don't understand how to get through the router issue. Could someone please explain?

  • A function's static and dynamic parent

    - by legends2k
    I'm reading Thinking in C++ (vol. 2): Whenever a function is called, information about that function is pushed onto the runtime stack in an activation record instance (ARI), also called a stack frame. A typical stack frame contains (1) the address of the calling function (so execution can return to it), (2) a pointer to the ARI of the function’s static parent (the scope that lexically contains the called function, so variables global to the function can be accessed), and (3) a pointer to the function that called it (its dynamic parent). The path that logically results from repetitively following the dynamic parent links is the dynamic chain, or call chain I'm unable to comprehend what the author means as function's static and dynamic parent. Also am not able to differentiate between item 1, 2 or 3. They all seem to be the same. Can someone please explain this passage to me?

  • How does Qt implement signals and slots?

    - by anton
    Can someone explain to me the basic idea of Qt signals&slots mechanism IMPLEMENTATION? I want to know what all those Q_OBJECT macros do "in plain C++". This question is NOT about signals&slots usage. added: I know that Qt uses moc compiler to transform Qt-C++ in plain C++. But what does moc do? I tried to read "moc_filename.cpp" files but I have no idea what can something like this mean void *Widget::qt_metacast(const char *_clname) { if (!_clname) return 0; if (!strcmp(_clname, qt_meta_stringdata_Widget)) return static_cast<void*>(const_cast< Widget*>(this)); return QDialog::qt_metacast(_clname); } Thanks in Advance, anton

  • Is there a Maven plugin to generate AS3 classes from Java for BlazeDS ?

    - by Maskime
    Hi, I'm looking for a maven plugin that would generate ActionScript3 classes from Java classes in order to access them by object remoting. I've seen FlexMojo but it uses the GraniteDS generator wich create some problems when it comes to map Enum objects (wich can be fix through a workaround that is describe here : http://dev.c-ware.de/confluence/display/PUBLIC/Flexmojos+generated+AS3+model+with+Enum+support+using+BlazeDS?focusedCommentId=7634946&#comment-7634946 if you've googled your way here this might be useful) when working with BlazeDS. Everything that i found so far are people who explain how to generate VO classes on flex side using Flash Builder 4, but this solution can not be used in an industrial developpement environnement. Thanks in advance for any leads on this matter.

  • How to build a java applet?

    - by Stefano Borini
    Most of the tutorials around explain how to create a java applet: create a .java file with a class, compile it with javac, put the .class somewhere, add a proper tag in the html. However, I'm not able to find anything about the best practices to build and release a complex applet, made of multiple classes and with additional libraries. How is the build/release process for this case ? What is it needed to go from my java project to the final .jar to put on the web ? I'm working with pure Eclipse, no plugins.

  • Metric 3d reconstruction

    - by srand
    I'm trying to reconstruct 3D points from 2D image correspondences. My camera is calibrated. The test images are of a checkered cube and correspondences are hand picked. Radial distortion is removed. After triangulation the construction seems to be wrong however. The X and Y values seem to be correct, but the Z values are about the same and do not differentiate along the cube. The 3D points look like as if the points were flattened along the Z-axis. What is going wrong in the Z values? Do the points need to be normalized or changed from image coordinates at any point, say before the fundamental matrix is computed? (If this is too vague I can explain my general process or elaborate on parts)

  • Performance of DrawingVisual vs Canvas.OnRender for lots of constantly changing shapes

    - by romkyns
    I'm working on a game-like app which has up to a thousand shapes (ellipses and lines) that constantly change at 60fps. Having read an excellent article on rendering many moving shapes, I implemented this using a custom Canvas descendant that overrides OnRender to do the drawing via a DrawingContext. The performance is quite reasonable, although the CPU usage stays high. However, the article suggests that the most efficient approach for constantly moving shapes is to use lots of DrawingVisual instances instead of OnRender. Unfortunately though it doesn't explain why that should be faster for this scenario. Changing the implementation in this way is not a small effort, so I'd like to understand the reasons and whether they are applicable to me before deciding to make the switch. Why could the DrawingVisual approach result in lower CPU usage than the OnRender approach in this scenario?

  • using pscp.exe for sftp transfer is very slow compared to filezilla

    I have a weird problem. I'm using pscp.exe from within a C# program (with process.start) to upload files to an SFTP server. Now I have set up a new server with the same program, where I upload to the same SFTP server as before, but It runs incredibly slow in the new server. The weird thing is that when I try uploading the files manually via FileZilla, the upload goes as fast as expected, but not when using the program. Can anyone explain this? Am I missing something obvious like a windows setting or something?
