• Generic Text Only printer driver mangles control codes

  - by Terry

  If an escape character (or most other characters < 0x20) is sent to the generic / text only printer it gets printed as a period. Using the code in the WinDDK is it possible to 'correct' this behaviour so that it passes it through unmodified? The general scenario for this is that some application ('user app') outputs a document to a windows printer. My application requires this data in plain text form and so what I do is run a generic / text only printer that talks to a virtual com port. This generally works fine except where the 'user app' outputs binary data to the print queue without using the correct mechanism (which seems to work fine on some printer drivers, such as the Epson POS ones, but not the generic / text only one). I've tried changing the print processor selection without success and also tried looking at the gtt files to see if I could readily map in these characters as though they were printable, but the minidriver tool won't let me do that. Any suggestions?

• Bit manipulation, permutate bits

  - by triktae

  Hi. I am trying to make a loop that loops through all different integers where exactly 10 of the last 40 bits are set high, the rest set low. The reason is that I have a map with 40 different values, and I want to sum all different ways ten of these values can be multiplied. (This is just out of curiosity, so it's really the "bitmanip"-loop that is of interest, not the sum as such.) If I were to do this with e.g. 2 out of 4 bits, it would be easy to set all manually, 0011 = 7, 0101 = 5, 1001 = 9, 0110 = 6, 1010 = 10, 1100 = 12, but with 10 out of 40 I can't seem to find a method to generate these effectively. I tried, starting with 1023 ( = 1111111111 in binary), finding a good way to manipulate this, but with no success. I've been trying to do this in C++, but it's really the general method(if any) that is of interest. I did some googling, but with little success, if anyone has a good link, that would of course be appreciated too. :)

• HMM for perspective estimation in document image, can't understand the algorithm

  - by maximus

  Hello! Here is a paper, it is about estimating the perspective of binary image containing text and some noise or non text objects. PDF document The algorithm uses the Hidden Markov Model: actually two conditions T - text B - backgrouond (i.e. noise) It is hard to understand the algorithm itself. The question is that I've read about Hidden Markov Models and I know that it uses probabilities that must be known. But in this algorithm I can't understand, if they use HMM, how do they get those probabilities (probability of changing the state from S1 to another state for example S2)? I didn't find anything about training there also in that paper. So, if somebody understands it, please tell me. Also is it possible to use HMM without knowing the state change probabilities?

• Copy Structure To Another Program

  - by Steven

  Long story, long: I am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure). LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file. I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure. When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure, populate the structure from the data file, then call the method to transfer the data back to the website. Long story, short: How do you recommend I transfer (copy) an instance of a structure from one .NET program to a VB.NET program? Ideas considered: sockets, temp file, xml file, config file, web services, CSV, some type of serialization, shared memory

• IIS website is sending multiple content-type headers for zip files

  - by frankadelic

  We have a problem with an IIS5 server. When certain users/browsers click to download .zip files, binary gibberish text sometimes renders in the browser window. The desired behavior is for the file to either download or open with the associated zip application. Initially, we suspected that the wrong content-type header was set on the file. The IIS tech confirmed that .zip files were being served by IIS with the mime-type "application/x-zip-compressed". However, an inspection of the HTTP packets using Wireshark reveals that requests for zip files return two Content-Type headers. Content-Type: text/html; charset=UTF-8 Content-Type: application/x-zip-compressed Any idea why IIS is sending two content-type headers? This doesn't happen for regular HTML or images files. It does happen with ZIP and PDF. Is there a particular place we can ask the IIS tech to look? Or is there a configuration file we can examine?

• Creating an AST node in Erlang

  - by dagda1

  Hi, I am playing about with Erlang and I am trying to write a simple arithmetic parser. I want to try and parse the following expression: ((12+3)-4) I want to parse the expression into a stack of AST nodes. When parsing this expression, I would first of all create a binary expression for the (12+3) expression which would look something like this in C#: var binaryStructure = new BinaryStructure(); binaryStructure.Left = IntegerLiteralExpression(12); binaryStructure.Right = IntegerLiteralExpression(4); binaryStructure.Operator = binaryExpression.Operator != BinaryOperatorType.Addition; I am quite new to Erlang and I am wondering how I would go about creating a structure like this in Erlang that I can place on a List that I would use as the stack of expressions. Can anyone suggest how to create such a tree like structure? Would a function be a good fit? Thanks Paul

• How to encrypt the mobile configuration profiles in iOS (in OTA deployments)?

  - by user1353477

  I am trying to sign and encrypt .mobileconfig profiles for iOS devices. Signing works perfectly using openssl::pkcs7 sign function in ruby, however using encrypt function, I get an encrypted data but Safari fails to install the profile saying "Invalid Profile". There are two questions in this regard: Which data from the .mobileconfig profile is actually encrypted that goes into the .. section of the EncryptedPayloadContent ? Is the data in binary format (.der) or base64 encoded? Any help in this regard would be helpful as APPLE severly lacks any documentation in encrypting the profiles.

• Best approach for building a multiplattform graphical interface for a command-line application

  - by Werner

  Hi, I developed a command line application, whose binary runs in Linux, Windows and Mac OSX. It reads some text input files, but I realize that some special users can not handle this. I would then like to build some kind of graphical interface, where the user only finds buttons and scroll bars for selecting the input parameters, a big "run" button, and then it reads the output of the program and makes some figures. I also need that everything gets finally packed in a single file, which uses only static libraries, so the user just needs to copy the file to his/her machine and run it. I would like to know what is the best open source and multi-platform approach to do this. 10 years ago I played a bit with something similar on DEC machines, so I guess that nowadays the situation has probably improved a bit. P.S. For designing the graphical interface, I am looking for a graphical approach, where you add buttons, scroll bars with the mouse P.S. 2: the interface is really simple, just need less than 10 buttons, 5 text fields and 2 scrolla bars Thanks

• How to install python physics engine

  - by None

  I want a python physics engine that works on mac and makes it easy to simulate physics. I have VPython and it works fine, but it is not quite what I want. VPython just shows visual elements and all the physics is in formulas. I looked at the documentation for PyODE and it looked like more what I want. It allowed you to add forces to masses and have worlds and things like that. When I tried to install PyODE (I am using a Mac), it didn't work. One reason was that I didn't have pyrex (I do have Cython, so maybe there is some way to have it use that?), but the other was that I didn't have ode installed. I looked and realized that PyODE is dependent on ode. I tried to install ode but that didn't work. Is there some documentation or binary or something that makes it easy to install PyODE on a mac? Or is there a similar module?

• Debian Package Control file Question.

  - by AJ

  Hello, I need to create a debian package for a java application. In my package there a .jar file which is executable , a script which will run this jar file and a .so file for fmod. I read the tutorial provided at http://tldp.org/HOWTO/html_single/Debian-Binary-Package-Building-HOWTO/ My question is in control file there is a Depends field which basically mentions the packages that need to installed in order to install my application. How do i find which packages are required for my application. I followed the instructions provided in the link for one of the .so and did ~/Desktop/PennTotalRecall/native/fmod/lib/linux64$ dpkg -S libfmodex64-4.28.09.so dpkg: libfmodex64-4.28.09.so not found. It gives above result. Also my application requires java 1.5 to be installed in order for it to run. How do I specify in my debian package. Thanks, AJ

• C: sprintf and recursion

  - by Shinka

  In C, is it possible to use recursion within the sprintf function ? For some reason I get a segmentation fault when I do it: inline char *TreeNode_toString(const TreeNode *node) { char *out; if(TreeNode_isExternal(node)) // If the node has no children... { sprintf(out, "%s:%.2f", node->name, node->distance); } else // The node is strictly binary, so it will have two non-null children { char *l = TreeNode_toString(node->l); // l = left child char *r = TreeNode_toString(node->r); // r = right child sprintf(out, "(%s,%s):%.2f", l, r, node->distance); } return out; }

• how to get an SDP record for bluetooth service??

  - by user302798

  Hi I'm new to both winsock and bluetooth programming. I need to develop a bluetooth service to run on a pc. Looking at the MSDN library they say to use WSASetService(http://msdn.microsoft.com/en-us/library/aa362921%28VS.85%29.aspx) function to publish a service. The problem is that the WSAQUERYSET(http://msdn.microsoft.com/en-us/library/aa362920%28VS.85%29.aspx) structure, that has to be passed to WSASetService, needs a binary SDP record and i don't know how to get it. In the Windows embedded section of the MSDN library they describe a procedure to obtain an SDP record using Bthnscreate. I installed Windows CE 6 to use this tool but i can't find it in the install directory nor in the entire system. How can i get an SDP record? Thanks!

• Why does mysqldump need to be fully pathed when called from a controller or model?

  - by Kris

  When I call mysqldump from a controller or model I need to fully path the binary, when I call it from Rake I don't need to. If I do not fully path I get a zero byte file... I can confirm both processes are run using the same user. # Works in a controller, model and Rake task system "/usr/local/mysql/bin/mysqldump -u root #{w.database_name} > #{target_file}" # Only works in a Rake task system "mysqldump -u root #{w.database_name} > #{target_file}" If I call the Rake task from the action it also fails (zero byte file). OS: Mac Ruby 1.8.6 EDIT: I use Etc.getpwuid(Process.uid).name to get the User of the current process

• download zip file using java?

  I am downloading zip file from web server using Java but somehow I am loosing about 2kb in each file. I don't know why since same code works fine with other formats, e.g, text, mp3 and extra. any help is appreciated? here is my code. public void download_zip_file(String save_to) { try { URLConnection conn = this.url.openConnection(); conn.setDoOutput(true); conn.setDoInput(true); conn.setRequestProperty("content-type", "binary/data"); InputStream in = conn.getInputStream(); FileOutputStream out = new FileOutputStream(save_to + "tmp.zip"); byte[] b = new byte[1024]; int count; while ((count = in.read(b)) > 0) { out.write(b, 0, count); } out.close(); in.close(); } catch (IOException e) { e.printStackTrace(); } }

• removing duplicate strings from a massive array in java efficiently?

  - by Preator Darmatheon

  I'm considering the best possible way to remove duplicates from an (Unsorted) array of strings - the array contains millions or tens of millions of stringz..The array is already prepopulated so the optimization goal is only on removing dups and not preventing dups from initially populating!! I was thinking along the lines of doing a sort and then binary search to get a log(n) search instead of n (linear) search. This would give me nlogn + n searches which althout is better than an unsorted (n^2) search = but this still seems slow. (Was also considering along the lines of hashing but not sure about the throughput) Please help! Looking for an efficient solution that addresses both speed and memory since there are millions of strings involved without using Collections API!

• How was non-decimal money represented in software?

  - by dan04

  A lot of the answers to the questions about the accuracy of float and double recommend the use of decimal for monetary amounts. This works because today all currencies are decimal except MGA and MRO, and those have subunits of 1/5 so are still decimal-friendly. But what about the software used in U.S. stock markets when prices were in 1/16ths of dollar? The accuracy of binary data types wouldn't have been an issue, right? Going further back, how did pre-1971 British accounting software deal with pounds, shillings, and pence? Did their versions of COBOL have a special PIC clause for it? Were all amounts stored in pence? How was decimalisation handled?

• XAMPP or MAMP on Mac OS X 10.6.2 (Snow Leopard)

  - by Steve

  I just bought a new MacBook Pro which comes with Snow Leopard 10.6.2 (Mac OS X 10.6.2). I am used to using XAMPP as my local development server on XP. Since Mac OS X is based on Unix, I was thinking on activating/installing all the necessary stuff as I would normally do on Linux. However, I am not quite ready to be playing around with the system at this point so having an external package would be a nice temporary solution I think. The question is whether I should go with MAMP or XAMPP. Does anybody have any suggestions? The Pro and Cons I suppose. As far as I know, Mac OS X comes with Apache2 and PHP5. Would MAMP or XAMPP modify the existing Apache and PHP installation? Any comments on how I should proceed? PS: Eventually I would use the default installation of Apache and PHP, and install a binary package of MySQL but time for development is an essence and I don't have time to familiarize myself with Mac OS X.

• How fast can you make linear search?

  - by Mark Probst

  I'm looking to optimize this linear search: static int linear (const int *arr, int n, int key) { int i = 0; while (i < n) { if (arr [i] >= key) break; ++i; } return i; } The array is sorted and the function is supposed to return the index of the first element that is greater or equal to the key. They array is not large (below 200 elements) and will be prepared once for a large number of searches. Array elements after the n-th can if necessary be initialized to something appropriate, if that speeds up the search. No, binary search is not allowed, only linear search.

• How to embed images in a single HTML / PHP file?

  - by Tatu Ulmanen

  Hi, I am creating a lightweight, single-file database administration tool and I would like to bundle some small icons with it. What is the best way to embed images in a HTML/PHP file? I know a method using PHP where I would call the same file with a GET parameter that would output hardcoded binary data with the correct header, but that seems a bit complicated. Can I use something to pass the image directly in a CSS background-image declaration? This would allow me to utilize the CSS sprite technique. Browser support isn't an issue here, so more exotic methods are welcome also. EDIT Does someone have a link/example to how to generate Data URL's properly with PHP? I'd figure echo 'data:image/png;base64,'.base64_encode(file_get_contents('image.png')) would suffice but I could be wrong.

• In Subversion, I know when a file was added, what's the quickest way to find out when it was deleted

  - by Eric Johnson

  OK, so suppose I know I added file "foo.txt" to my Subversion repository at revision 500. So I can do a svn log -v http://svnrepo/path/foo.txt@500, and that shows all the files added at the same time. What's the fastest way to find when the file was deleted after it was added? I tried svn log -r500:HEAD -v http://svnrepo/path/foo.txt@500, but that gives me "path not found" - perhaps obviously, because the file "foo.txt" doesn't exist at "HEAD". I can try a binary search algorithm going forward through revisions (and that would certainly be faster than typing this question), but is there a better way?

• md5 hash for file without File Attributes

  - by Glennular

  Using the following code to compute MD5 hashs of files: Private _MD5Hash As String Dim md5 As New System.Security.Cryptography.MD5CryptoServiceProvider Dim md5hash() As Byte md5hash = md5.ComputeHash(Me._BinaryData) Me._MD5Hash = ByteArrayToString(md5hash) Private Function ByteArrayToString(ByVal arrInput() As Byte) As String Dim sb As New System.Text.StringBuilder(arrInput.Length * 2) For i As Integer = 0 To arrInput.Length - 1 sb.Append(arrInput(i).ToString("X2")) Next Return sb.ToString().ToLower End Function We are getting different hashes depending on the create-date and modify-date of the file. We are storing the hash and the binary file in a SQL DB. This works fine when we upload the same instance of a file. But when we save a new instance of the file from the DB (with today's date as the create/modify) on the file-system and then check the new hash versus the MD5 stored in the DB they do not match, and therefor fail a duplicate check. How can we check for a file hash excluding the file attributes? or is there a different issue here?
