• DLL Load Failed: %1 is not a valid win32 application

  - by glittershark

  So I have a situation where I need to make binary patches and then be able to apply them from within python. I found bsdiff which looks like a great algorithm and has a python extension module, but that extension module doesn't have a windows installer past Python 2.5 Alright, so having never even written C seriously, let alone attempted a python extension module, I set out to compile it myself. After a few hours of bashing my head against a DLL load error with MinGW32, I managed to get it compiled and built using the setup.py provided in the source of the project. However, upon importing the resulting bsdiff module, I get: ImportError: DLL load failed: %1 is not a valid Win32 application. Any advice?

• inputMismatchException Java reading doubles from plain text file

  - by user939287

  Using double variable = inputFile.nextDouble(); Gives the mismatch error and I can't figure out why... Anyone know what's up? The input file is just a bunch of doubles like 5.0... Okay here is the code snippet String fileName; Scanner scanner = new Scanner(System.in); System.out.println("\nEnter file name that contains the matrix and vector: "); fileName = scanner.nextLine(); Scanner inputFile = new Scanner(fileName); double a1 = inputFile.nextDouble(); the input file is a plain text document .txt in this format 5.0 4.0 -3.0 4.0 2.0 5.0 6.0 5.0 -2.0 -13.0 4.0 12.0 I don't understand why it wouldn't take those as doubles... As far as what its expecting the format of the file to be... I suppose binary? isn't that the default? I didn't specify in the code...

• Erlang bit syntax variable issue

  - by Jimmy Ruska

  Is there any way to format this so it's a valid expression, without adding another step? <<One:8,_:(One*8)>> = <<1,9>>. * 1: illegal bit size These work <<One:8,_:(1*8)>> = <<1,9>>. <<1,9>> <<Eight:8,_:Eight>> = <<8,9>>. <<8,9>> I'm trying to parse a binary with nested data with list comprehensions instead of stacking accumulators.

• Customizing compare in bsearch()

  - by Richard Smith

  I have an array of addresses that point to integers ( these integers are sorted in ascending order). They have duplicate values. Ex: 1, 2, 2, 3, 3, 3, 3, 4, 4...... I am trying to get hold of all the values that are greater than a certain value(key). Currently trying to implement it using binary search algo - void *bsearch( const void *key, const void *base, size_t num, size_t width, int ( __cdecl *compare ) ( const void *, const void *) ); I am not able to achieve this completely, but for some of them. Would there be any other way to get hold of all the values of the array, with out changing the algorithm I am using?

• python array.array with strings as data type

  - by Gladius

  Is there an object that acts like array.array, yet can handle strings (or character arrays) as its data type? It should be able to convert the string array to binary and back again, preferably with null terminated strings, however fixed length strings would be acceptable. >>> my_array = stringarray(['foo', 'bar']) >>> my_array.tostring() 'foo\0bar\0' >>> re_read = stringarray('foo\0bar\0') >>> re_read[:] ['foo', 'bar'] I will be using it with arrays that contain a couple million strings.

• How to check for a file's authenticity ?

  - by Ale_x

  Let's say I write a game application. I want the level of the player to be stored in an external file. How can I prevent a hacker from writing and modifying the file to put another level ? I want the file to be modified by my application only. I can sign the file's content with a key, but then this key will be stored in the application, therefore it would be possible for a hacker to decompile the binary and find the key. Is there any way to do this ?

• File upload with tdo-miniforms not working

  - by user338109

  I am using the TDO-miniforms plugin for wordpress. I have a form set up that lets the user submit files. The files are successfully uploaded to the tmp-folder, but once the post is created they are not copied into the allocated post folder. The only thing that is created in the folder with a post id is a file called array. It seems like the file holds the binary data of the uploaded files. The “correct” urls are appended to the post content I am running wordpress 2.9.2 on snow leopard using Mamp.

• How to pass multiple params to function in python?

  - by user1322731

  I am implementing 8bit adder in python. Here is the adder function definition: def add8(a0,a1,a2,a3,a4,a5,a6,a7,b0,b1,b2,b3,b4,b5,b6,b7,c0): All function parameters are boolean. I have implemented function that converts int into binary: def intTObin8(num): bits = [False]*8 i = 7 while num >= 1: if num % 2 == 1: bits[i] = True else: bits[i] = False i = i - 1 num /= 2 print bits return [bits[x] for x in range(0,8)] I want this function to return 8 bits. And to use this two functions as follows: add8(intTObin8(1),intTObin8(1),0) So the question is: How to pass 8 parameters using one function?

• Read from socket

  - by Alberto

  I need to read from an AF_UNIX socket to a buffer using the function read from C, but I don't know the buffer size. I think the best way is to read N bytes until the read returns 0 (no more writers in the socket). Is this correct? Is there a way to guess the size of the buffer being written on the socket? I was thinking that a socket is a special file. Opening the file in binary mode and getting the size would help me in knowing the correct size to give to the buffer? I'm a very new to C, so please keep that in mind.

• Persisting Serializable Objects in Hibernate

  - by VeeArr

  I am attempting to persist objects that contain some large Serializable types. I want Hibernate to automatically generate my DDL (using Hibernate annotations). For the most part, this works, but the default database column type used by Hibernate when persisting these types is tinyblob. Unfortunately, this causes crashes when attempting to persist my class, because these types will not fit within the length of tinyblob. However, if I manually set the type (using @Column(columnDefinition="longblob")), it works fine. Is there any way to make the default binary type longblob instead of tinyblob, so that I don't need to manually specify the @Column annotation on each field?

• Sending two servlet responses per request

  - by sangi

  Hi, I write, because I can not solve the following problem. I have a servlet that processes some information. In response I put both text and binary content. How do I get two response, then two html page, starting from the same request? is a thing possible? The first response should continue to do what he does now, while the second would appear to make a popup window to save an image. There are easier ways to achieve the same result? Many thanks in advance

• Why does Apple use Objective-C for iPhone development? (App Store)

  - by Luca Matteis

  I'm interested to know your opinion on why Apple uses a language such as Objective-C for app development. Does Apple's app store allow apps written only in this language? Does apple even look at your source-code or does it just care of the binary output? I learned that most of their app rejection (in the app store) is based upon apps crashing (probably memory leaks in which Objective-c is not very efficient unless you use a GC). Why not let developers use a safer language, like a scripting language? I think these are important questions for a developer (I don't even use Apple's products) because it seems like Apple's app store is the MOST successful app sale place on the web.

• What is this VB6 method doing?

  - by Craig

  We are converting a VB6 application to C# (4.0). and have come across a method in VB6 that we're battling to understand. Public Sub SaveToField(fldAttach As ADODB.Field) Dim bData() As Byte Dim nSize As Long nSize = Len(m_sEmail) bData = LngToByteArray(nSize) fldAttach.AppendChunk bData If nSize > 0 Then bData = StringToByteArray(m_sEmail) fldAttach.AppendChunk bData End If nSize = Len(m_sName) bData = LngToByteArray(nSize) fldAttach.AppendChunk bData If nSize > 0 Then bData = StringToByteArray(m_sName) fldAttach.AppendChunk bData End If bData = LngToByteArray(m_nContactID) fldAttach.AppendChunk bData End Sub It seems like it's doing some binary file copy type thing, but I'm not quite understanding. Could someone explain so that we can rewrite it?

• Java deserialization speed

  - by celicni

  I am writing a Java application that among other things needs to read a dictionary text file (each line is one word) and store it in a HashSet. Each time I start the application this same file is being read all over again (6 Megabytes unicode file). That seemed expensive, so I decided to serialize resulting HashSet and store it to a binary file. I expected my application to run faster after this. Instead it got slower: from ~2,5 seconds before to ~5 seconds after serialization. Is this expected result? I thought that in similar cases serialization should increase speed.

• iPhone App on iPad - What is the extra effort?

  - by hol

  I started to develop an iPhone App for a client but the binary not yet submitted to Apple. My client asked me whether they can run the iPhone App also on the iPad. I am not sure what to answer. I am away from home and cannot even check how this all works in XCode. I wonder whether I have to submit two binaries two Apple - one for iPhone and one for iPad - or how this all works? If somebody with experience can explain me. Basically I need to figure out how much more effort I have to consider if it is only making the app work on the iPad. I do not mean the effort to redesign the whole app being a real "iPad app". Just to make it work and when somebody downloads the app and it can be for an iPhone and for an iPad and it does not matter.

• PHP Losing variable data

  - by Conor B

  Hi, I'm having an issue with PHP losing data in a variable. There is quite a bit of data in the variable, because it basically contains a binary file, but I'm wondering if this is cause for it to completely lose it's information. Looking at a snippet from my code which is used to deal with email attachments: var_dump($data) if (array_key_exists('filename', $params) || array_key_exists('name', $params)) { var_dump($data) ... } The first var_dump gives the desired output of the file: "string(283155) " --Apple-Mail-5-930065543 ... etc while the second gives an output of: string(0) "" ... string(0) "" Any idea why this is happening? Does PHP just drop data in variables if they are really large? (I didn't think so, as I've never had this problem before) If so, any workaround? Thanks!

• wstring in union

  - by Oops

  Hi, I'd like to define a union, for reading special kind of binary files. The union should have two members one of int and the other a kind of string, or any other that's the question; what is the best way to do this? union uu { int intval; wstring strval; uu(){ memset(this, 0, sizeof(this)); } } it says: "Member strval of union has copy constructor" I think strval should have a * or a &; how would you define it? thanks in advance Oops

• grep --include command doesn't work in OSX zsh

  - by icemelon

  I am following the best answer on Finding all files containing a text string in linux to search string in my project. This is my command grep --include=*.rb -rnw . -e "pattern" Zsh tells me that zsh: no matches found: --include=*.rb It seems that grep doesn't support --include option. When I type grep --help, it returns usage: grep [-abcDEFGHhIiJLlmnOoPqRSsUVvwxZ] [-A num] [-B num] [-C[num]] [-e pattern] [-f file] [--binary-files=value] [--color=when] [--context[=num]] [--directories=action] [--label] [--line-buffered] [--null] [pattern] [file ...] no --include here. Is my grep version too old? Or is there something wrong with my command?

• Generics not so generic !!

  - by Aymen

  Hi I tried to implement a generic binary search algorithm in scala. Here it is : type Ord ={ def <(x:Any):Boolean def >(x:Any):Boolean } def binSearch[T <: Ord ](x:T,start:Int,end:Int,t:Array[T]):Boolean = { if (start > end) return false val pos = (start + end ) / 2 if(t(pos)==x) true else if (t(pos) < x) binSearch(x,pos+1,end,t) else binSearch(x,start,pos-1,t) } everything is OK until I tried to actually use it (xD) : binSearch(3,0,4,Array(1,2,5,6)) the compiler is pretending that Int not a member of Ord, well what shall I do to solve this ? Thanks

• Check if an object is order-able in python?

  - by sortfiend

  How can I check if an object is orderable/sortable in Python? I'm trying to implement basic type checking for the __init__ method of my binary tree class, and I want to be able to check if the value of the node is orderable, and throw an error if it isn't. It's similar to checking for hashability in the implementation of a hashtable. I'm trying to accomplish something similar to Haskell's (Ord a) => etc. qualifiers. Is there a similar check in Python?

• Why doesn't pppd over ssh work here? Why can't I kill pppd?

  - by Peter V. Mørch

  I'm trying to setup a simple ppp tunnel over ssh. It works on several machines just fine. But on one machine, pppd gets "stuck": > pgrep pppd | xargs ps up USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 4178 0.0 0.1 3020 1088 pts/1 Ds+ 05:28 0:00 /usr/sbin/pppd Any attempt to kill it (even sudo kill -9 4178) has no effect that I can see. strace -p 4178 also hangs similarly. After it has been started for a while, I start getting messages in dmesg like shown below. It is started like so from another machine: ssh -t root@server /usr/sbin/pppd passive noauth When I do this to one of the machines that work, the remote end's pppd spits out garbage/binary data to the console (as expected). When I do it to the one that fails, I get no output from pppd, but the ssh session eventually times out. If I instead ssh to the machine, and then run /usr/sbin/pppd passive noauth in a separate step I also get the expected binary output. I now have a couple of questions: What could be up with the one machine where pppd fails? I don't even know where to start looking... What could be the difference between ssh -t root@server /usr/sbin/pppd passive noauth in a single step and ssh root@server and /usr/sbin/pppd passive noauth in two steps? How can it be that I can't kill the process even with sudo kill -9? The only way I know is to reboot. (I've tried searching for something similar but didn't get anywhere so I'm sorry I don't have any more leads) Any ideas? The problem machine runs in debian on VMware "hardware" (as do the ones that work) and it exhibits the problem when cloned and on both debian lenny (original) and squeeze (after upgrade) dmesg entries: [ 1198.727248] INFO: task pppd:4178 blocked for more than 120 seconds.

• The Oracle Enterprise Linux Software and Hardware Ecosystem

  - by sergio.leunissen

  It's been nearly four years since we launched the Unbreakable Linux support program and with it the free Oracle Enterprise Linux software. Since then, we've built up an extensive ecosystem of hardware and software partners. Oracle works directly with these vendors to ensure joint customers can run Oracle Enterprise Linux. As Oracle Enterprise Linux is fully--both source and binary--compatible with Red Hat Enterprise Linux (RHEL), there is minimal work involved for software and hardware vendors to test their products with it. We develop our software on Oracle Enterprise Linux and perform full certification testing on Oracle Enterprise Linux as well. Due to the compatibility between Oracle Enterprise Linux and RHEL, Oracle also certifies its software for use on RHEL, without any additional testing. Oracle Enterprise Linux tracks RHEL by publishing freely downloadable installation media on edelivery.oracle.com/linux and updates, bug fixes and security errata on Unbreakable Linux Network (ULN).
