  • Illegal instruction in Assembly

    - by Natasha
    I really do not understand why this simple code works fine in the first attempt but when putting it in a procedure an error shows: NTVDM CPU has encountered an illegal instruction CS:db22 IP:4de4 OP:f0 ff ff ff ff The first code segment works just fine: .model small .stack 100h .code start: mov ax,@data mov ds,ax mov es,ax MOV AH,02H ;sets cursor up MOV BH,00H MOV DH,02 MOV DL,00 INT 10H EXIT: MOV AH,4CH INT 21H END However This generates an error: .model small .stack 100h .code start: mov ax,@data mov ds,ax mov es,ax call set_cursor PROC set_cursor near MOV AH,02H ;sets cursor up MOV BH,00H MOV DH,02 MOV DL,00 INT 10H RET set_cursor ENDP EXIT: MOV AH,4CH INT 21H END Note: Nothing is wrong with windows config. I have tried many sample codes that work fine Thanks

  • Disabling URL decoding in nginx proxy

    - by Tomasz Nurkiewicz
    When I browse to this URL: http://localhost:8080/foo/%5B-%5D server (nc -l 8080) receives it as-is: GET /foo/%5B-%5D HTTP/1.1 However when I proxy this application via nginx: location /foo { proxy_pass http://localhost:8080/foo; } The same request routed through nginx port is forwarded with path decoded: GET /foo/[-] HTTP/1.1 Decoded square brackets in the GET path are causing the errors in the target server (HTTP Status 400 - Illegal character in path...) as they arrive un-escaped. Is there a way to disable URL decoding or encode it back so that the target server gets the exact same path when routed through nginx? Some clever URL rewrite rule?

  • Multiple lines of text to a single map

    - by steven
    I've been trying to use Hadoop to send N amount of lines to a single mapping. I don't require for the lines to be split already. I've tried to use NLineInputFormat, however that sends N lines of text from the data to each mapper one line at a time [giving up after the Nth line]. I have tried to set the option and it only takes N lines of input sending it at 1 line at a time to each map: job.setInt("mapred.line.input.format.linespermap", 10); I've found a mailing list recommending me to override LineRecordReader::next, however that is not that simple, as that the internal data members are all private. I've just checked the source for NLineInputFormat and it hard codes LineReader, so overriding will not help. Also, btw I'm using Hadoop 0.18 for compatibility with the Amazon EC2 MapReduce.

  • Open Source Contribution for a newbie programmer.

    - by sasayins
    Hi, I am teaching programming to my nephews and I want them to improve their skills by contributing to open source projects. Now my question is, do you know any open source project that suit for a newbie programmer. What I mean is, the project does not have a large codebase, the project is very interesting and the project is written in C because I chose C language as their starting language but you can suggest other project made in other language. My goal here are to improve their logic by reading other source codes, familiarize to the available development tools like bug tracker, version control system, etc. and open their interest in open source community. Thanks. =)

  • Inverted question mark only on Microsoft Office applications

    - by inerte
    My dad has a notebook and the key which has the "/?°" symbols acts like ctrl. Known factory problem. Anyway, his keyboard also has a "?" marked under the "w" key. Pressing ctrl + alt + w will display the "?" character (question, interrogation mark). Except on Office applications, like Word and Outlook, which will output "¿". I've searched Word and Outlook menus looking for a parameter that could be, somehow, remapping the notebooks keyboards, applying different regional configurations, language, or encodings. Since it only happens on Office apps, I believe the solution is within its options, but I was unable to find it where. Pressing ctrl + alt gr + w will display ? correctly, but I am stumped by this problem. I could remap the keys and make "/?° behave correctly, but my curiosity now is eating me alive. Why only on Office?

  • Changes user's email on crowd doesn't apply in confluence

    - by donamir
    Hi It's my configuration: Atlassian Crowd Version: 2.0.2 (Build:#409 - 06-10-2009) Atlassian Confluence 3.0.2 I can't change users' emails in Confluence because I use Crowd as external user management. So I have to change users' emails in Crowd but changes doesn't apply in Confluence. Even users has access to crowd user console and can login to Crowd and view their profile and edit their email password but changed emails doesn't apply in Confluence. What should I do? Is it a bug? Also I should mention that emails contains dot character(.). I posted my question to Atlassian forum 3 days ago but there's no answer yet!

  • Unable to incorporate Eclispe JDT codeAssist facilities outside a Plug-in

    - by shi kui
    Using Eclipse jdt facilities, you can traverse the AST of java code snippets as follows: ASTParser ASTparser = ASTParser.newParser(AST.JLS3); ASTparser.setSource("package x;class X{}".toCharArray()); ASTparser.createAST(null).accept(...); But when trying to perform code complete & code selection it seems that I have to do it in a plug-in application since I have to write codes like IFile file = ResourcesPlugin.getWorkspace().getRoot().getFile(new Path(somePath)); ICodeAssist i = JavaCore.createCompilationUnitFrom(f); i.codeComplete/codeSelect(...) Is there anyway that I can finally get a stand-alone java application which incorporates the jdt code complete/select facilities? thx a lot! shi kui

  • Are their any suggestions for this new assembly language?

    - by Noctis Skytower
    Greetings! Last semester in college, my teacher in the Computer Languages class taught us the esoteric language named Whitespace. In the interest of learning the language better with a very busy schedule (midterms), I wrote an interpreter and assembler in Python. An assembly language was designed to facilitate writing programs easily, and a sample program was written with the given assembly mnemonics. Now that it is summer, a new project has begun with the objective being to rewrite the interpreter and assembler for Whitespace 0.3, with further developments coming afterwards. Since there is so much extra time than before to work on its design, you are presented here with an outline that provides a revised set of mnemonics for the assembly language. This post is marked as a wiki for their discussion. Have you ever had any experience with assembly languages in the past? Were there some instructions that you thought should have been renamed to something different? Did you find yourself thinking outside the box and with a different paradigm than in which the mnemonics were named? If you can answer yes to any of those questions, you are most welcome here. Subjective answers are appreciated! Stack Manipulation (IMP: [Space]) Stack manipulation is one of the more common operations, hence the shortness of the IMP [Space]. There are four stack instructions. hold N Push the number onto the stack copy Duplicate the top item on the stack copy N Copy the nth item on the stack (given by the argument) onto the top of the stack swap Swap the top two items on the stack drop Discard the top item on the stack drop N Slide n items off the stack, keeping the top item Arithmetic (IMP: [Tab][Space]) Arithmetic commands operate on the top two items on the stack, and replace them with the result of the operation. The first item pushed is considered to be left of the operator. add Addition sub Subtraction mul Multiplication div Integer Division mod Modulo Heap Access (IMP: [Tab][Tab]) Heap access commands look at the stack to find the address of items to be stored or retrieved. To store an item, push the address then the value and run the store command. To retrieve an item, push the address and run the retrieve command, which will place the value stored in the location at the top of the stack. save Store load Retrieve Flow Control (IMP: [LF]) Flow control operations are also common. Subroutines are marked by labels, as well as the targets of conditional and unconditional jumps, by which loops can be implemented. Programs must be ended by means of [LF][LF][LF] so that the interpreter can exit cleanly. L: Mark a location in the program call L Call a subroutine goto L Jump unconditionally to a label if=0 L Jump to a label if the top of the stack is zero if<0 L Jump to a label if the top of the stack is negative return End a subroutine and transfer control back to the caller exit End the program I/O (IMP: [Tab][LF]) Finally, we need to be able to interact with the user. There are IO instructions for reading and writing numbers and individual characters. With these, string manipulation routines can be written. The read instructions take the heap address in which to store the result from the top of the stack. print chr Output the character at the top of the stack print int Output the number at the top of the stack input chr Read a character and place it in the location given by the top of the stack input int Read a number and place it in the location given by the top of the stack Question: How would you redesign, rewrite, or rename the previous mnemonics and for what reasons?

  • Counting multiple entries in a MySQL database?

    - by Aaron
    Hi all, I'm trying to count multiple entries in a MySQL database, I know how to use COUNT(), but the exact syntax I want to get the results I need eludes me. The problem: Table structure: ID, CODE, AUTHOR, COUNTRY, TIMESTAMP. Code, Author and Country overlap many times in the table. I am trying to discover if there is one simple query that can be ran to return (using WHERE clause on COUNTRY) the author field, the code field, and then a final field that counts the number of times the CODE was present in the query result. So, theoretically I could end up with an array like: array('author', 'code', 'codeAppearsNTimes'); Authors also have varying codes associated with them, so I don't want the results merged. I suppose the end result would be: 'This author is associated with this code this many times'. Is this possible with MySQL? Thanks in advance.

  • How to refresh to entire device's screen (Windows Mobile)?

    - by walidad
    Hi everybody, I'm working on a simple application that draws an alpha-blended picture on the screen's Device Context every 2 secs, I want to refresh the screen contents before the drawing operation (To erase the drawn pic), I have used many many trick but unfortunately, the screen won't refresh correctly, some regions still keep portions of the drawn pic I'm really frustrated from this issue :( These are the sources codes I have used, I'm using C# SendMessage(HWND_BROADCAST, WM_SYSCOLORCHANGE, IntPtr.Zero, IntPtr.Zero); // wasted time in the refreshing process is enough to keep this. UpdateWindow(HWND_BROADCAST);// does not work at all! InvalidateRect(IntPtr.Zero,IntPtr.Zero,true); // the same goes here. SendMessage(HWND_BROADCAST, WM_PAINT, IntPtr.Zero, IntPtr.Zero); // pfffff ! SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, new IntPtr(SPI_SETNONCLIENTMETRICS), IntPtr.Zero); // trying to refresh the explorer, no resutl I used also EnumWindows and call back , very slow and does not fit my case. I wanna refresh the whole screen Help please! Regards Waleed

  • translating play in HTML to python

    - by aharon
    So, I'd like to represent one of Shakespeare's plays, Hamlet, into the following objects (maybe this isn't the best representation, if so please tell me): class Play(): acts = [] ... def add_act(self, act): acts.append(act) class Act(): scenes = [] ... def add_scene(self, scene): scenes.append(scene) class Scene(): elems = [] def __init__(self, title, setting=""): ... def add_elem(self, elem): elems.append(elem) ... class StageDirection(): # elem def __init__(self, text): ... class Line(): # elem def __init__(self, id, text, character = None): ... # A None character represents a continuation from the previous line # id could be, for example, 1.1.1 There are other methods, of course, for printing and such in each of the classes. The question is, how do I get a structure based on these classes (or something like them) from HTML 4 code that looks like this: <H3>ACT I</h3> <h3>SCENE I. Elsinore. A platform before the castle.</h3> <p><blockquote> <i>FRANCISCO at his post. Enter to him BERNARDO</i> </blockquote> <A NAME=speech1><b>BERNARDO</b></a> <blockquote> <A NAME=1.1.1>Who's there?</A><br> </blockquote> <A NAME=speech2><b>FRANCISCO</b></a> <blockquote> <A NAME=1.1.2>Nay, answer me: stand, and unfold yourself.</A><br> </blockquote> <A NAME=speech3><b>BERNARDO</b></a> <blockquote> <A NAME=1.1.3>Long live the king!</A><br> </blockquote> <A NAME=speech4><b>FRANCISCO</b></a> <blockquote> <A NAME=1.1.4>Bernardo?</A><br> </blockquote> <A NAME=speech5><b>BERNARDO</b></a> <blockquote> <A NAME=1.1.5>He.</A><br> </blockquote> <!-- for more, see the source of shakespeare.mit.edu/hamlet/full.html --> translating that into something like this: play = Play() actI = Act() sceneI = Scene("Scene I", "Elsinore. A platform before the castle.") sceneI.add_elem(StageDirection("Francisco at his post. Enter to him Bernardo.")) sceneI.add_elem(Line("Bernardo", "Who's there?")) ... Of course, I don't expect all the code—but what libraries and, when there aren't libraries, logic should I use? Thanks. (This is for a future opensource project and me learning Python for fun—not homework.)

  • How do I compile Android Browser (or other android-supplied applications)

    - by afriza
    I want to add support for Arabic (or other languages which are currently unsupported) to the applications supplied by android platform (e.g. Browser) without having root-access. To add Arabic support (at least displaying only) in a normal application (using developer SDK), I will need to: Add fonts Modify (reshape) the characters to be rendered For illustration, if I have string a aaa, I will need to change a aaa into a bcd because letter a at the beginning, middle, and end of a word need to be changed to b,c and d respectively) But now I want to compile android's Browser (and other apps). I am planning to get the source codes for these applications and their dependencies and bundle them as stand-alone applications which do not require root-access, and thus do not void the warranty. Other solutions which void the warranty can be obtained here. My Questions: Is the application's (e.g. Browser's) source code + 'developer SDK' enough to accomplish this? Do I need to get the source code + the development environment for the android platform? Any tips?

  • Quick backup system for large projects

    - by kamziro
    I've always backed up all my source codes into .zip files and put it in my usb drive and uploaded to my server somewhere else in the world.. however I only do this once every two weeks, because my project is a little big. Right now my project directories (I have a few of them) contains a hierarchy of c++ files in it, and interspersed with them are .o files which would make backing up take a while if not ignored. What tools exist out there that will let me just back things up efficiently, conveniently and lets me specify which file types to back up (lots of .png, .jpg and some text types in there), and which directories to be ignored (esp. the build dirs)? Or is there any ingenious methods out there that people use?

  • Regex to validate SMTP Responses?

    - by Alix Axel
    I'm writing a regular expression that can interactively validate SMTP responses codes, once the SMTP dialog is completed it should pass the following regex (some parentheses added for better readability): ^(220)(250){3,}(354)(250)(221)$ Or with(out) authentication: ^(220)(250)((334){2}(235))?(250){2,}(354)(250)(221)$ I'm trying to do rewrite the above regexes so that I can interactively check if the dialog is going as expected, otherwise politely send a QUIT command and close the connection saving bandwidth and time, but I'm having a hard time writing an optimal regex. So far I've managed to come up with: ^(220(250(334(235(250(354(250(221)?)?)?){0,})?){0,2})?)?$ Which, besides only matching authenticated connections, has some bugs... For instance, it matches: 220250334235250354250221 220250334334235250354250221 I've also tried the following modification: ^(220(250)?)?((334(235)?){2})?(250(354(250(221)?)?)?){0,}$ This one accepts non-authenticated responses but it fails to match 220250334 and wrongly matches 220250334334235250354250221 (at least 2 250 are needed before the 354 response code). Can someone help me out with this? Thanks in advance.

  • Calculating co-ordinate of a point on a path given a distance

    - by Alex
    I'm working on a project that surveys the condition of a road or highway using a calibrated trip computer connected to a rugged-PC. An operator keys in defect codes as they travel along a pre-defined route. I need to show an indicator on the map screen that shows the vehicles current position, taking into account the distance data from the trip computer. I know the exact lat lon co-ordinates at the starting point of each section of road, and the road is made up of a series of points. The question is: how can I calculate the lat lon co-ordinates of the vehicle assuming that it has continued on the route and traveled a certain distance (e.g. 1.4km). The co-ordinates would be 'locked onto' the road line, as shown in blue on the diagram below. Thanks, Alex
