  • Shell complains 'cannot execute binary file'

    - by Negai
    Hi everyone, I've playing around with linux and noticed that for some mysterious reason commands like '/bin/sh ' just will not work. Each time I'm trying to start a process it yields 'cannot execute binary file' error message. m@sanctuary:~$ sh sed /bin/sed: /bin/sed: cannot execute binary file When I first launch sh and try to execute sed, it succeeds. I'm starting to loose my wits. It would be just great, if somebody could help me. Thank you.

  • C# convert binary data to string?

    - by Tom
    Hi, just going through the registry retrieving values and binary is making my file outputer fall. I was wondering how could I convert Subkey.getValue(value[i]) into a String if the Value type is binary? Thank you in advance

  • Set a C++ bitset from a binary input steam

    - by Jon
    I have an input stream from a binary file. I want to create a bitset for the first 5 bits of the stream. Here is the code I have so far: ifstream is; is.open ("bin_file.out", ios::binary ); bitset<5> first_five_bits; is >> first_five_bits; // always is set to default 00000

  • Are binary protocols dead?

    - by Earlz
    It seemed like there use to be way more binary protocols because of the very slow internet speeds of the time (dialup). I've been seeing everything being replaced by HTTP and SOAP/REST/XML. Why is this? Are binary protocols really dead or are they just less popular? Why would they be dead or less popular?

  • Boost::binary<> [c++][Boost]

    - by atch
    Hi, Is there anything in boost libraries like binary? For example I would like to write: binary<10101> a; I'm ashamed to admit that I've tried to find it (Google, Boost) but no results. They're mention something about binary_int< but I couldn't find neither if it is available nor what header file shall I include; Thanks for help.

  • Reading binary data from stdin

    - by thebeav
    Is it possible to read stdin as binary data in Python 2.6? If so, how? I see in the Python 3.1 documentation that this is fairly simple, but the facilities for doing this in 2.6 don't seem to be there. If the methods described in 3.1 aren't available, is there a way to close stdin and reopen in in binary mode?

  • Powershell overruling Perl binmode?

    - by hippietrail
    I have a Perl script which creates a binary file while scanning a very large text file. It outputs to STDOUT which I redirect in the commandline to a file. To optimize it I'm making changes then seeing how low it takes to run. On Linux for this I use the "time" command. On Windows the best way to time a program seemed to be to PowerShell's "measure-command". This seemed to work fine but I noticed the generated files were larger. On examination I found that the files generated from within PowerShell begin with a BOM and contain CRLF pairs! My Perl script has a "binmode STDOUT" directive and does work correctly in a normal dosbox. Is this a bug or misfeature in PowerShell or measure-command? Has it affected others creating binary files by means other than Perl? Googling hasn't turned anything up so far. I'm using Perl 5.12, PowerShell v1.0 and Windows XP.

  • Files built with a makefile are disapearing (including the binary)

  • Changing the name of a binary packaged application and its evoking command

    - by jerkstore
    I have taken the source code of a large project, App A, and made many modifications to it to produce my version, App B. Both App A and App B compile cleanly on Debian and Red Hat and now I would like to build binary packages for both platforms. The last modification I need to make is ensuring App B can be installed alongside App A without any interference. I should be able to evoke both application-a and application-b in the terminal and have both be listed as separate software in whatever desktop environment is present. The projects have a debian/ folder (containing rules, control, etc.) and an rpm/ folder containing a SPEC file. Currently, building and installing the .rpm and .deb packages works except that App B is recognized as App A and therefore does not meet the aforementioned requirements. ldd shows the programs have the same exact dependencies and I am not able to pursue static linking of libraries. What modifications do I need to make to my project to achieve the desired outcome? Please be specific as I do not have much experience with the packaging process.

  • Why use binary files to stack up different versions on DMSs?

    - by edgarator
    I've used both Liferay and Alfresco trying to use them as the Document Management System for an intranet. I noticed the following: They use the file system and the database to store files They use a GUID to name the file on the filesystem and that GUID is used as an Id in the database. The GUID-named file is a binary file The GUID-named binary file stores all versions for a given file The path for the file in the DMS doesn't match the one in the file system The URL makes reference to the GUID when a certain file is requested What I want to know is why is this, and what would be the best way of doing it. Like how to would you create the binary file (zip?), and what parts would you keep in the binary file and what parts would you store in the database (meta-data, path?). I'm assuming some of the benefits of doing it like this. As having the same URL for a file, regardless of its current document path. And having only one file even if the file has changed names over time.

  • Simple Android Binary Text Clock

    - by Hristo
    Hello, I want to create a simple android binary clock but my application crashes. I use 6 textview fields: 3 for the decimal and 3 for the binary representation of the current time (HH:mm:ss). Here's the code: import java.text.SimpleDateFormat; import java.util.Calendar; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class Binary extends Activity implements Runnable { Thread runner; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); if (runner == null) { //start the song runner = new Thread(this); runner.start(); } } @Override public void run() { TextView hours_dec = (TextView) findViewById(R.id.hours_dec); TextView mins_dec = (TextView) findViewById(R.id.mins_dec); TextView secs_dec = (TextView) findViewById(R.id.secs_dec); TextView hours_bin = (TextView) findViewById(R.id.hours_bin); TextView mins_bin = (TextView) findViewById(R.id.mins_bin); TextView secs_bin = (TextView) findViewById(R.id.secs_bin); SimpleDateFormat hours_sdf = new SimpleDateFormat("HH"); SimpleDateFormat mins_sdf = new SimpleDateFormat("mm"); SimpleDateFormat secs_sdf = new SimpleDateFormat("ss"); Calendar cal = Calendar.getInstance(); while (runner != null) { WaitAMoment(); cal.getTime(); hours_dec.setText(hours_sdf.format(cal.getTime())); mins_dec.setText(mins_sdf.format(cal.getTime())); secs_dec.setText(secs_sdf.format(cal.getTime())); hours_bin.setText(String.valueOf(Integer.toBinaryString(Integer.parseInt((String) hours_dec.getText())))); mins_bin.setText(String.valueOf(Integer.toBinaryString(Integer.parseInt((String) mins_dec.getText())))); secs_bin.setText(String.valueOf(Integer.toBinaryString(Integer.parseInt((String) secs_dec.getText())))); } } protected void WaitAMoment() { try { Thread.sleep(100); } catch (InterruptedException e) { }; } }`

  • Iterate with binary structure over numpy array to get cell sums

    - by Curlew
    In the package scipy there is the function to define a binary structure (such as a taxicab (2,1) or a chessboard (2,2)). import numpy from scipy import ndimage a = numpy.zeros((6,6), dtype=numpy.int) a[1:5, 1:5] = 1;a[3,3] = 0 ; a[2,2] = 2 s = ndimage.generate_binary_structure(2,2) # Binary structure #.... Calculate Sum of result_array = numpy.zeros_like(a) What i want is to iterate over all cells of this array with the given structure s. Then i want to append a function to the current cell value indexed in a empty array (example function sum), which uses the values of all cells in the binary structure. For example: array([[0, 0, 0, 0, 0, 0], [0, 1, 1, 1, 1, 0], [0, 1, 2, 1, 1, 0], [0, 1, 1, 0, 1, 0], [0, 1, 1, 1, 1, 0], [0, 0, 0, 0, 0, 0]]) # The array a. The value in cell 1,2 is currently one. Given the structure s and an example function such as sum the value in the resulting array (result_array) becomes 7 (or 6 if the current cell value is excluded). Someone got an idea?

  • how to write binary copy of structure array to file

    - by cerr
    I would like to write a binary image of a structure array to a binary file. I have tried this so far: #include <stdio.h> #include <string.h> #define NUM 256 const char *fname="binary.bin"; typedef struct foo_s { int intA; int intB; char string[20]; }foo_t; void main (void) { foo_t bar[NUM]; bar[0].intA = 10; bar[0].intB = 999; strcpy(bar[0].string,"Hello World!"); Save(bar); printf("%s written succesfully!\n",fname); } int Save(foo_t* pData) { FILE *pFile; int ptr = 0; int itr = 0; pFile = fopen(fname, "w"); if (pFile == NULL) { printf("couldn't open %s\n", fname); return; } for (itr = 0; itr<NUM; itr++) { for (ptr=0; ptr<sizeof(foo_t); ptr++) { fputc((unsigned char)*((&pData[itr])+ptr), pFile); } fclose(pFile); } } but the compiler is saying aggregate value used where an integer was expected fputc((unsigned char)*((&pData[itr])+ptr), pFile); and I don't quite understand why, what am I doing wrong? Thanks!

  • A question on getting number of nodes in a Binary Tree

    - by Robert
    Dear all, I have written up two functions (pseudo code) for calculation the number of nodes and the tree height of a Binary Tree,given the root of the tree. Most importantly,the Binary Tree is represented as the First chiled/next sibling format. so struct TreeNode { Object element; TreeNode *firstChild; TreeNode *nextSibling; } Calculate the # of nodes: public int countNode(TreeNode root) { int count=0; while(root!=null) { root= root.firstChild; count++; } return count; } public int countHeight(TreeNode root) { int height=0; while(root!=null) { root= root.nextSibling; height++; } return height; } This is one of the problem I saw on an algorithm book,and my solution above seems to have some problems,also I didn't quite get the points of using this First Child/right sibling representation of Binary Tree,could you guys give me some idea and feedback,please? Cheers!

  • Storing "binary" data type in C program

    - by puchu
    I need to create a program that converts one number system to other number systems. I used itoa in Windows (Dev C++) and my only problem is that I do not know how to convert binary numbers to other number systems. All the other number systems conversion work accordingly. Does this involve something like storing the input to be converted using %? Here is a snippet of my work: case 2: { printf("\nEnter a binary number: "); scanf("%d", &num); itoa(num,buffer,8); printf("\nOctal %s",buffer); itoa(num,buffer,10); printf("\nDecimal %s",buffer); itoa(num,buffer,16); printf("\nHexadecimal %s \n",buffer); break; } For decimal I used %d, for octal I used %o and for hexadecimal I used %x. What could be the correct one for binary? Thanks for future answers!

  • Re-packaging commercial software into RPM packages

    - by gac
    The situation is this - I have a small CentOS 5 "cluster" (currently 7 machines, but potential for more) which run a commercially available software package that's distributed essentially in tarball format (it's actually a zip file with a mixture of Windows/Linux binaries and an installation shell script with no potential for automation). I'd like to re-package this somehow into an RPM package (ideally that I can throw onto a self-hosted yum repository) in order to keep these "cluster" machines both up to date and consistent. I could do 7 manual installations, but there's scope for error. As I understand it, I'll need to accomplish the following tasks: add a non-privileged user to the target system for running the daemon without unnecessary root privileges package the binary files themselves up from the final installation location on a separate build machine (probably under /opt/package for sanity's sake). No source is available. add a firewall hole in order for the end-users to be able to communicate with the "cluster" nodes add a cron task which can start the daemon on @reboot I'm coming up with plenty of good packaging resources so far, but all are based on the traditional method (i.e. if I were the vendor packaging up my source files), rather than re-packaging a ton of binary files from an already-installed instance of the application, which is the only option available to me. Anyone have any good resources they can share for achieving this goal? Thanks!

  • Find largest rectangle containing all zero's in an N X N binary matrix

    - by Rajendra
    Given an N X N binary matrix (containing only 0's or 1's). How can we go about finding largest rectangle containing all 0's? Example: I 0 0 0 0 1 0 0 0 1 0 0 1 II->0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 <--IV 0 0 1 0 0 0 IV is a 6 X 6 binary matrix, return value in this case will be Cell 1: (2, 1) and Cell 2: (4, 4). Resulting sub-matrix can be square or rectangle. Return value can be size of the largest sub-matrix of all 0's also, for example, here 3 X 4.

  • "Bad binary signature" in ASP.NET MVC application

    - by David M
    We are getting the error above on some pages of an ASP.NET MVC application when it is deployed to a 64 bit Windows 2008 server box. It works fine on our development machines, though these are 32 bit XP. Just wondered if anyone had encountered this before, and has any suggestions? Details as follows: Bad binary signature. (Exception from HRESULT: 0x80131192) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Runtime.InteropServices.COMException: Bad binary signature. (Exception from HRESULT: 0x80131192) All projects are set to compile for Any CPU, and are compiled in Release mode. The ASP.NET site is precompiled, and the precompiled build is on a 64 bit Windows 2008 TeamCity build agent. Thanks in advance. EDIT We're still plagued by this. I have looked at all the binaries in the website's bin directory using corflags.exe. None has the 32BIT flag set, and all have a CorFlags value of 9 except for Antlr3.Runtime.dll which has a value of 1. The problem only affects certain pages, and it seems to be those which use FluentValidation (including FluentValidation.Mvc and FluentValidation.xValIntegration assemblies). None of these shows anything out of the ordinary when inspected with corflags.exe, and there are no odd looking dependencies revealed by ildasm. When built locally (32 bit Windows XP) the site deploys and runs fine. When built on the build agents (64 bit Windows 2008 Server) the site displays these errors. The site runs in Integrated Pipeline mode, and is not set to 32 bit. The stack trace is: [COMException (0x80131192): Bad binary signature.

  • How do I change my iPhone App binary filename

    I get the following error when I try to upload the application on iTunes Connect: "Binary file names cannot contain a space. Please rename your binary file and try again." If I try to Validate the Application in XCode, I get: "My Application.ipa: filename may not contain whitespace" So I guess I have to find a way to rename this .ipa file. I don't want to change my product name which has to stay "My Application". How can I do that? Thanks!

  • XStream <-> Alternative binary formats (e.g. protocol buffers)

    - by sehugg
    We currently use XStream for encoding our web service inputs/outputs in XML. However we are considering switching to a binary format with code generator for multiple languages (protobuf, Thrift, Hessian, etc) to make supporting new clients easier and less reliant on hand-coding (also to better support our message formats which include binary data). However most of our objects on the server are POJOs with XStream handling the serialization via reflection and annotations, and most of these libraries assume they will be generating the POJOs themselves. I can think of a few ways to interface an alternative library: Write an XStream marshaler for the target format. Write custom code to marshal the POJOs to/from the classes generated by the alternative library. Subclass the generated classes to implement the POJO logic. May require some rewriting. (Also did I mention we want to use Terracotta?) Use another library that supports both reflection (like XStream) and code generation. However I'm not sure which serialization library would be best suited to the above techniques.
