  • hexdump confusion

    - by zedoo
    I am playing with the unix hexdump utility. My input file is UTF-8 encoded, containing a single character ñ, which is C3 B1 in hexadecimal UTF-8. hexdump test.txt 0000000 b1c3 0000002 Huh? This shows B1 C3 - the inverse of what I expected! Can someone explain? For getting the expected output I do: hexdump -C test.txt 00000000 c3 b1 |..| 00000002 I was thinking I understand encoding systems..

  • Deliberately crashing an external process under Windows

    - by Terry
    I would like to synthesise a native code fault. This is so that we can see where in particular some debugging output gets put when that occurrs. Pskill (from Sys-Internals) causes a graceful exit. DotCrash.exe doesn't seem to be available anymore from Microsoft directly. Is there any way to externally cause a crash in a process?

  • Encoding problem (Hebrew UTF8) in WordPress

    - by Tal Galili
    Hi all, I have a blog (of a friend) I am failing to fix: http://www.nivcalderon.com/ The language of the website is Hebrew, but the encoding scrambles the output, and I can't find how to fix it. I tried changing the DB colliation to be utf8_general_ci. I added this: define('DB_COLLATE', 'utf8_general_ci'); To the wp-config (and also this: define('DB_CHARSET', 'utf8'); But removed it later, since it didn't seem to fix the problem) Any ideas of what else to do ? Thanks

  • how to create a SETUP.EXE wrapper for an MSI file using NSIS

    - by user222846
    I want to wrap a existing msi installer file into NSIS installer executable. Because there is not any option to change the icon of the msi file. I just want to customize the icon of the output setup.exe. Along with this I would also want to make sure that NSIS does not add any extra user interface into my installer. Have anybody an idea to do this ? Thanks in advance.

  • iPad: How to let a user write a hand-written note using a Pogo(like) stylus?

    - by MikeN
    How could I let a user jot a quick hand-written note on an iPad using a Pogo-like stylus? (Or by using their finger, some kind of stylus makes it more legible feasible.) Initial thoughts: 1) Open GL canvas? 2) Store the output as a .png/.jpg snapshot of the openGL screen (by taking a screenhot of the iPad? 3) Would the note be limited to one screenshot, could there be a scrollable area notepad to write out a long note?

  • Arbitrary Form Processing with Drupal

    - by Aaron
    I am writing a module for my organization to cache XML feeds to static files to an arbitrary place on our webserver. I am new at Drupal development, and would like to know if I am approaching this the right way. Basically I: Expose a url via the menu hook, where a user can enter in a an output directory on the webserver and press the "dump" button and then have PHP go to drupal and get the feed xml. I don't need help with that functionality, because I actually have a prototype working in Python (outside of Drupal).. Provide a callback for the form where I can do my logic, using the form parameters. Here's the menu hook: function ncbi_cache_files_menu() { $items = array(); $items['admin/content/ncbi_cache_files'] = array( 'title' => 'NCBI Cache File Module', 'description' => 'Cache Guide static content to files', 'page callback' => 'drupal_get_form', 'page arguments' => array( 'ncbi_cache_files_show_submit'), 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_NORMAL_ITEM, ); return $items; } I generate the form in: function ncbi_cache_files_show_submit() { $DEFAULT_OUT = 'http://myorg/foo'; $form[ 'ncbi_cache_files' ] = array( '#type' => 'textfield', '#title' => t('Output Directory'), '#description' => t('Where you want the static files to be dumped. This should be a directory that www has write access to, and should be accessible from the foo server'), '#default_value' => t( $DEFAULT_OUT ), '#size' => strlen( $DEFAULT_OUT ) + 5, ); $form['dump'] = array( '#type' => 'submit', '#value' => 'Dump', '#submit' => array( 'ncbi_cache_files_dump'), ); return system_settings_form( $form ); } Then the functionality is in the callback: function ncbi_cache_files_dump( $p, $q) { //dpm( get_defined_vars() ); $outdir = $p['ncbi_cache_files']['#post']['ncbi_cache_files']; drupal_set_message('outdir: ' . $outdir ); } The question: Is this a decent way of processing an arbitrary form in Drupal? I not really need to listen for any drupal hooks, because I am basically just doing some URL and file processing. What are those arguments that I'm getting in the callback ($q)? That's the form array I guess, with the post values? Is this the best way to get the form parameters to work on? Thanks for any advice.

What I would like to do is something like this capture a frame then do some image processing on it and display the output and then move on to the next frame. Can I can access to web-cam frame events or is there any efficient way to achieve this?

  • Is there anything like deal() for normal MATLAB arrays?

    - by jjkparker
    When dealing with cell arrays, I can use the deal() function to assign cells to output variables, such as: [a, b, c] = deal(myCell{:}); or just: [a, b, c] = myCell{:}; I would like to do the same thing for a simple array, such as: myArray = [1, 2, 3]; [a, b, c] = deal(myArray(:)); But this doesn't work. What's the alternative?

  • Still failing a function, not sure why...ideas on test cases to run?

    - by igor
    I've been trying to get this Sudoku game working, and I am still failing some of the individual functions. All together the game works, but when I run it through an "autograder", some test cases fail.. Currently I am stuck on the following function, placeValue, failing. I do have the output that I get vs. what the correct one should be, but am confused..what is something going on? EDIT: I do not know what input/calls they make to the function. What happens is that "invalid row" is outputted after every placeValue call, and I can't trace why.. Here is the output (mine + correct one) if it's at all helpful: http://pastebin.com/Wd3P3nDA Here is placeValue, and following is getCoords that placeValue calls.. void placeValue(Square board[BOARD_SIZE][BOARD_SIZE]) { int x,y,value; if(getCoords(x,y)) { cin>>value; if(board[x][y].permanent) { cout<< endl << "That location cannot be changed"; } else if(!(value>=1 && value<=9)) { cout << "Invalid number"<< endl; clearInput(); } else if(validMove(board, x, y, value)) { board[x][y].number=value; } } } bool getCoords(int & x, int & y) { char row; y=0; cin>>row>>y; x = static_cast<int>(toupper(row)); if (isalpha(row) && (x >= 'A' && x <= 'I') && y >= 1 && y <= 9) { x = x - 'A'; // converts x from a letter to corresponding index in matrix y = y - 1; // converts y to corresponding index in matrix return (true); } else if (!(x >= 'A' && x <= 'I')) { cout<<"Invalid row"<<endl; clearInput(); return false; } else { cout<<"Invalid column"<<endl; clearInput(); return false; } }

  • Know of any Java garbage collection log analysis tools?

    - by braveterry
    I'm looking for a tool or a script that will take the console log from my web app, parse out the garbage collection information and display it in a meaningful way. I'm starting up on a Sun Java 1.4.2 JVM with the following flags: -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails The log output looks like this: 54.736: [Full GC 54.737: [Tenured: 172798K->18092K(174784K), 2.3792658 secs] 257598K->18092K(259584K), [Perm : 20476K->20476K(20480K)], 2.4715398 secs] Making sense of a few hundred of these kinds of log entries would be much easier if I had a tool that would visually graph garbage collection trends.

  • Patterns for wrapping a command line tool in another language

    - by Tom Duckering
    I'm currently writing some Java to wrap around an extensive command line tool. It feels like I'm writing a lot of similar code. I'm wondering if there are any established patterns for wrapping command line tools - passing arguments and handling output and so on. Specific examples in Java would obviously be great, but any general suggestions or pointers are welcome too.
