  • Using Python simplejson for transmitting JSON to another server results in unicode encoding problems

    - by Mark
    Hi there, I'm encoding a string with Python's simplejson library with special characters: hello testing spécißl characters plusses: +++++ special chars :œ?´®†¥¨ˆøp“ß?ƒ©??°¬O˜çv?˜µ== However, when I encode it and transmit it to the other machine (using POST), it turns out like this: {'message': ['{"body": "hello testing sp\\u00e9ci\\u00dfl characters\\n\\nplusses: \\n\\nspecial chars :\\u0153\\u2211\\u00b4\\u00ae\\u2020\\u00a5\\u00a8\\u02c6\\u00f8\\u03c0\\u201c\\u00df\\u2202\\u0192\\u00a9\\u02d9\\u2206\\u02da\\u00ac\\u03a9\\u2248\\u00e7\\u221a\\u222b\\u02dc\\u00b5\\u2264\\u2265"}']} The + signs are completely stripped and the rest are in this unicode(?) format. My code for this is: data = {'body': data_string} data_encoded = json.dumps(data) Any ideas? Thanks! Edit: I've tried using json.dumps(data, ensure_ascii=False) but it results in a UnicodeError ordinal not in range error.

  • how to generate large image in compact framework

    - by Buthrakaur
    I need to generate large images (A4 image at 200 DPI, PNG format would be fine) in my compact framework application. This is impossible to do in standard way due to memory limitations (such big image will throw OOMException). Is there any library which offers file-backed stream image generation? Or I could generate many smaller stripes of images (each stripe representing a row of the large image) using standard Bitmap approach, but I need to merge them together afterwards - is there any method how to merge many smaller images into one large without having to instantiate large Bitmap instance (which would again cause OOM)?

  • Temporary files & folders on Windows

    - by GRIGORE-TURBODISEL
    Emulating multithreading by loading a DLL multiple times (it's designed for this). Since LoadLibrary() doesn't really allow it, the DLL copies itself into a temporary file, via GetTempPath() and GetTempFileName(). It's a small file and upon thread destruction it frees the library and deletes the temporary file. Problem now is that the number of threads is configurable (maniacs can pick 50, 100, more) which basically exposes the risk of running unstable, crash and not go through the usual "delete temporary files" routine. Is it okay if I just leave those temporary files to die there? Does the OS usually clean the up by itself? Or should I write an autocleanup routine? If yes, how can I go about saving another temporary file to hold a list with those files, and not hit UAC restrictions or otherwise? Any ideas?

  • An easy way to replace fread()'s with reading from a byte array?

    - by Sam Washburn
    I have a piece of code that needs to be run from a restricted environment that doesn't allow stdio (Flash's Alchemy compiler). The code uses standard fopen/fread functions and I need to convert it to read from a char* array. Any ideas on how to best approach this? Does a wrapper exist or some library that would help? Thanks! EDIT: I should also mention that it's reading in structs. Like this: fread(&myStruct, 1, sizeof(myStruct), f);

  • Ideal timeout period for dns lookup

    - by railscoder
    In my rails app i do a nslookup using a ruby library resolv. If the site like dgdfgdfgdfg.com is entered its talking too long to resolve. in some instance like 20 sec.(mostly for non-existent sites) Because it cause the application to slowdown. So i though of introducing a timeout period for the dns lookup. What will be the ideal timeout period for the dns lookup so that resolution of actual site doesnt fail. will something like 10 sec will be fine?

  • Help need for openfast implementation

    - by ganuke
    Our stock exchange going to implement FAST messaging in their system in order to reduced the bandwidth usage. We have already implement the FIX based application to trade with Stock exchange. In future we need implement FIX FAST in our application to communicate with them. I found that OPEN FAST is FAST based library. But I do not have any idea how to start with it. I went through OpenFast web site but could not find much support on how to use templates and dictionaries. Can some one guide me or provide some resources to start with? Thanks in advance.

  • Cache an FTP connection via session variables for use via AJAX?

    - by Chad Johnson
    I'm working on a Ruby web Application that uses the Net::FTP library. One part of it allows users to interact with an FTP site via AJAX. When the user does something, and AJAX call is made, and then Ruby reconnects to the FTP server, performs an action, and outputs information. Every time the AJAX call is made, Ruby has to reconnect to the FTP server, and that's slow. Is there a way I could cache this FTP connection? I've tried caching in the session hash, but "We're sorry, but something went wrong" is displayed, and a TCP dump is outputted in my logs whenever I attempt to store it in the session hash. I haven't tried memcache yet. Any suggestions?

  • Include a Class in another model / class / lib

    - by jaycode
    I need to use function "image_path" in my lib class. I tried this (and couple of other variations): class CustomHelpers::Base include ActionView::Helpers::AssetTagHelper def self.image_url(source) abs_path = image_path(source) unless abs_path =~ /^http/ abs_path = "#{request.protocol}#{request.host_with_port}#{abs_path}" end abs_path end end But it didn't work. Am I doing it right? Another question is, how do I find the right class to include? For example if I look at this module: http://api.rubyonrails.org/classes/ActionView/Helpers/AssetTagHelper.html is there a rule of thumb how to include that module in a model / library / class / anything else ?

  • Newbie question about file formatting in Python

    - by user568041
    I'm writing a simple program in Python 2.7 using pycURL library to submit file contents to pastebin. Here's the code of the program: #!/usr/bin/env python2 import pycurl, os def send(file): print "Sending file to pastebin...." curl = pycurl.Curl() curl.setopt(pycurl.URL, "http://pastebin.com/api_public.php") curl.setopt(pycurl.POST, True) curl.setopt(pycurl.POSTFIELDS, "paste_code=%s" % file) curl.setopt(pycurl.NOPROGRESS, True) curl.perform() def main(): content = raw_input("Provide the FULL path to the file: ") open = file(content, 'r') send(open.readlines()) return 0 main() The output pastebin looks like standard Python list: ['string\n', 'line of text\n', ...] etc. Is there any way I could format it so it looks better and it's actually human-readable? Also, I would be very happy if someone could tell me how to use multiple data inputs in POSTFIELDS. Pastebin API uses paste_code as its main data input, but it can use optional things like paste_name that sets the name of the upload or paste_private that sets it private.

  • How do i translate this to "simpler" JavaScript?

    - by Julian Weimer
    Since i'm working with Titanium i realzed that its current JavaScript Interpreter doesn't accept specific coding-styles. So for for-loops and if-statements i have to have braces, even though i only want to span one line. Furthermore there is more i have to change if i want to use a Javascript Library like underscore.js. This is what Titanium doesn't want to see: if (!(result = result && iterator.call(context, value, index, list))) {_.breakLoop();} if (nativeSome && obj.some === nativeSome) {return obj.some(iterator, context);} var computed = iterator ? iterator.call(context, value, index, list) : value; computed >= result.computed && (result = {value : value, computed : computed}); Can i use a simpler syntax to describe the logic behind those lines of code?

  • Python elegant inverse function of int(string,base)

    - by random guy
    python allows conversions from string to integer using any base in the range [2,36] using: int(string,base) im looking for an elegant inverse function that takes an integer and a base and returns a string for example >>> str_base(224,15) 'ee' i have the following solution: def digit_to_char(digit): if digit < 10: return chr(ord('0') + digit) else: return chr(ord('a') + digit - 10) def str_base(number,base): if number < 0: return '-' + str_base(-number,base) else: (d,m) = divmod(number,base) if d: return str_base(d,base) + digit_to_char(m) else: return digit_to_char(m) note: digit_to_char() works for bases <= 169 arbitrarily using ascii characters after 'z' as digits for bases above 36 is there a python builtin, library function, or a more elegant inverse function of int(string,base) ?

  • A Combinations of Items in Given List

    - by mecablaze
    Hello stackoverflow, I'm currently in Python land. This is what I need to do. I have already looked into the itertools library but it seems to only do permutations. I want to take an input list, like ['yahoo', 'wikipedia', 'freebase'] and generate every unique combination of one item with zero or more other items... ['yahoo', 'wikipedia', 'freebase'] ['yahoo', 'wikipedia'] ['yahoo', 'freebase'] ['wikipedia', 'freebase'] ['yahoo'] ['freebase'] ['wikipedia'] A few notes. Order does not matter and I am trying to design the method to take a list of any size. Also, is there a name for this kind of combination? Thanks for your help!

  • How to get gesture IDs

    - by Colin Gough
    Is there anyway to get a list of gesture ids, from the gesture library that has been created using gesturebuilder. I want to link each gesture to an images, so some sort of an id or name is needed. I have looked at the samples and other online material avaialbe for gestures, and there is no information on this matter. Any help in this matter would be appreciated. Example: if (predictions.size() > 0) { Prediction prediction = predictions.get(0); if (prediction.score > 1.0) { if(prediction.best_score == Current_Image) { Correct(); Next_image(); } } }

  • How can I enable auto-updates in a Qt cross-platform app?

    - by FX
    I love applications that are able to update themselves without any effort from the user (think: Sparkle framework for Mac). Is there any code/library I can leverage to do this in a Qt app, without having to worry about the OS details? At least for Windows/Mac/user-owned-linux-binaries. I could integrate Sparkle on the Mac version, code something for the linux case (only for a standalone, user-owned binary; I won't mess with distros packaging, if my program is ever packaged), and find someone to help me on the Windows side, but that's horribly painful. Surely I'm not the only one who wants to provide this to users?

  • How can I create an http handler to redirect all traffic to HTML pages?

    - by Eitan
    Our company would like to redirect all calls to html files on our server to a separate page. The html pages are NOT in an asp.net application. In order to do this, I've been writing and IIS Handler in asp.net. 1) Is this possible to add an IIS handler to redirect static content that isn't served by any asp.net engine, i.e. stand alone files on the server? 2) If it is possible, how do I do this? I created an http handler in a class library. In the app.config I added the handler to the and sections. I added the DLL to the GAC, I changed the html mapping to my custom IIS dll and nothing works. Is there a tutorial or explanation from A to B on how to do this? Thanks. E p.s. I'm using IIS 7.5

  • Is there an easy way in Python to wait until certain condition is true?

    - by Checkers
    I need to wait in a script until a certain number of conditions become true? I know I can roll my own eventing using condition variables and friends, but I don't want to go through all the trouble of implementing it, since some object property changes come from external thread in a wrapped C++ library (Boost.Python), so I can't just hijack __setattr__ in a class and put a condition variable there, which leaves me with either trying to create and signal a Python condition variable from C++, or wrap a native one and wait on it in Python, both of which sound fiddly, needlessly complicated and boring. Is there an easier way to do it, barring continuous polling of the condition? Ideally it would be along the lines of res = wait_until(lambda: some_predicate, timeout) if (not res): print 'timed out'

  • Auto pointer for unsigned char array?

    - by Gianluca
    I'd need a class like std::auto_ptr for an array of unsigned char*, allocated with new[]. But auto_ptr only calls delete and not delete[], so i can't use it. I also need to have a function which creates and returns the array. I came out with my own implementation within a class ArrayDeleter, which i use like in this example: #include <Utils/ArrayDeleter.hxx> typedef Utils::ArrayDeleter<unsigned char> Bytes; void f() { // Create array with new unsigned char* xBytes = new unsigned char[10]; // pass array to constructor of ArrayDeleter and // wrap it into auto_ptr return std::auto_ptr<Bytes>(new Bytes(xBytes)); } ... // usage of return value { auto_ptr<Bytes> xBytes(f()); }// unsigned char* is destroyed with delete[] in destructor of ArrayDeleter Is there a more elegant way to solve this? (Even using another "popular" library)

  • SQL Compact Edition 3.5 SP 1 - LockTimeOutException - how to debug?

    - by Bob King
    Intermittently in our app, we encounter LockTimeoutExceptions being throw from SQL CE. We've recently upgraded to 3.5 SP 1, and a number of them seem to have gone away, but we still do see them occasionally. I'm certain it's a bug in our code (which is multi-threaded) but I haven't been able to pin it down precisely. Does anyone have any good techniques for debugging this problem? The exceptions log like this (there's never a stack trace for these exceptions): SQL Server Compact timed out waiting for a lock. The default lock time is 2000ms for devices and 5000ms for desktops. The default lock timeout can be increased in the connection string using the ssce: default lock timeout property. [ Session id = 6,Thread id = 7856,Process id = 10116,Table name = Product,Conflict type = s lock (x blocks),Resource = DDL ] Our database is read-heavy, but does seldom writes, and I think I've got everything protected where it needs to be. EDIT: SQL CE already automatically uses NOLOCK http://msdn.microsoft.com/en-us/library/ms172398(sql.90).aspx

  • Bit conversion operations in PHP

    - by Goro
    Hello, I find myself in need of performing bit-level conversion on variables in PHP. In more detail, I have a bit stream that is read as an integer by hardware, and I need to do some operations on the bits to make it into what its actually supposed to be (a float). I have to do this a few times for different formats, and the functionality I need is Being able to select and move individual bits in a variable Being able to cast statically one type of variable to the other (ie. int to float) I know php natively supports bitwise AND, OR, etc, and shift operations, but I was wondering if: there may already be a library in php that does this sort of thing I would be better off with delegating the calculations to some other language Thanks,

  • What's the best way to write to more files than the kernel allows open at a time?

    - by Elpezmuerto
    I have a very large binary file and I need to create separate files based on the id within the input file. There are 146 output files and I am using cstdlib and fopen and fwrite. FOPEN_MAX is 20, so I can't keep all 146 output files open at the same time. I also want to minimize the number of times I open and close an output file. How can I write to the output files effectively? I also must use the cstdlib library due to legacy code.

  • Does anyone know of a way to easily convert a PDF to a docx format programmatically

    - by Rob
    We have a couple 3rd party systems that give us PDFs. We would like to convert those PDFs for display on the web without using an Adobe product. Ideally we would like to use Silverlight to render the PDFs but are having trouble converting from a PDF to Xaml or using docx format as a middle man. There are lots of libraries that give PDFs but that is not what we need. If there is a library out there that does this, a .net lib would be preferable but we can run the conversion using the command line as well if that is an option.

  • Common Utility for Exception Searching

    - by Andrew
    I wrote this little helper method to search the exception chain for a particular exception (either equals or super class). However, this seems like a solution to a common problem, so was thinking it must already exist somewhere, possibly in a library I have already imported. So, any ideas on if/where this might exist? boolean exceptionSearch(Exception base, Class<?> search) { Throwable e = base; do { if (search.isAssignableFrom(e.getClass())) { return true; } } while ((e = e.getCause()) != null); return false; }

I am thinking of an idea, Please guide me if it is feasible and good enough Each log have Process name , Thread id , and Time stamp along with message. If I can create a intelligence to capture what is happing with time and display in a movie which user can view it like a normal video. Forward – backward etc. It will help to reach root cause fast and bug tracing will become easy. Please guide me on library in c++ using which I can draw diagrams and display as movie

  • On Memory Allocation and C++

    - by Arpan
    And I quote from MSDN http://msdn.microsoft.com/en-us/library/aa366533(VS.85).aspx: The malloc function has the disadvantage of being run-time dependent. The new operator has the disadvantage of being compiler dependent and language dependent. Now the questions folks: a) What do we mean that malloc is run-time dependent? What kind of dynamic memory allocation functions can be independent of run-time? This statement sounds real strange. b) new is language dependent? Of course it should be right? Are HeapAlloc, LocalAlloc etc language independent? c) From a pure performance perspective are the MSVC provided routines preferable? Arpan
