• Another sound not working post

  - by Thomas Smart

  Tried all the other "sound not working" posts i think, lost count. purge/reinstall alsa and pulse, reboot, add user to audio group, various lines in the alsa config file such as "options snd-hda-intel model=" then tried different options like generic, auto, basic, default, etc. tried pulseaudio -k && sudo alsa force-reload a few times, with and without rebooting.

• C#'s equivalent to VB.Net's DirectCast?

  - by Collin Sauve

  This has probably been asked before, but if it has, I can't find it. Does C# have an equivalent to VB.Net's DirectCast? I am aware that it has () casts and the 'as' keyword, but those line up to CType and TryCast. To be clear, these keywords do the following; CType/() casts: If it is already the correct type, cast it, otherwise look for a type converter and invoke it. If no type converter is found, throw an InvalidCastException. TryCast/"as" keyword: If it is the correct type, cast it, otherwise return null. DirectCast: If it is the correct type, cast it, otherwise throw an InvalidCastException. EDIT: After I have spelled out the above, some people have still responded that () is equivalent, so I will expand further upon why this is not true. DirectCast only allows for either Narrowing or Widening conversions on inheritance tree, it does not support conversions across different branches like () does. ie: C#, this compiles and runs: //This code uses a type converter to go across an inheritance tree double d = 10; int i = (int)d; VB.Net, this does NOT COMPILE 'Direct cast can only go up or down a branch, never across to a different one. Dim d as Double= 10 Dim i as Integer = DirectCast(d, Integer) The equivalent in VB.Net to my C# code is CType: 'This compiles and runs Dim d as Double= 10 Dim i as Integer = CType(d, Integer) (Edit again, I was originally using strings, I changed it to double... sorry)

• Implicit conversion between Scala collection types

  - by ebruchez

  I would like to implicitly convert between the Scala XML Elem object and another representation of an XML element, in my case dom4j Element. I wrote the following implicit conversions: implicit def elemToElement(e: Elem): Element = ... do conversion here ... implicit def elementToElem(e: Element): Elem = ... do conversion here ... So far so good, this works. Now I also need collections of said elements to convert both ways. First, do I absolutely need to write additional conversion methods? Things didn't seem to work if I didn't. I tried to write the following: implicit def elemTToElementT(t: Traversable[Elem]) = t map (elemToElement(_)) implicit def elementTToElemT(t: Traversable[Element]) = t map (elementToElem(_)) This doesn't look too ideal because if the conversion method takes a Traversable, then it also returns a Traversable. If I pass a List, I also get a Traversable out. So I assume the conversion should be parametrized somehow. So what's the standard way of writing these conversions in order to be as generic as possible?

• Checked and Unchecked operators don't seem to be working when...

  - by flockofcode

  1) Is UNCHECKED operator in effect only when expression inside UNCHECKED context uses an explicit cast ( such as byte b1=unchecked((byte)2000); ) and when conversion to particular type can happen implicitly? I’m assuming this since the following expression throws a compile time error: byte b1=unchecked(2000); //compile time error 2) a) Do CHECKED and UNCHECKED operators work only when resulting value of an expression or conversion is of an integer type? I’m assuming this since in the first example ( where double type is being converted to integer type ) CHECKED operator works as expected: double m = double.MaxValue; b=checked((byte)m); // reports an exception , while in second example ( where double type is being converted to a float type ) CHECKED operator doesn’t seem to be working. since it doesn't throw an exception: double m = double.MaxValue; float f = checked((float)m); // no exception thrown b) Why don’t the two operators also work with expressions where type of a resulting value is of floating-point type? 2) Next quote is from Microsoft’s site: The unchecked keyword is used to control the overflow-checking context for integral-type arithmetic operations and conversions I’m not sure I understand what exactly have expressions and conversions such as unchecked((byte)(100+200)); in common with integrals? Thank you

• SVG to JPEG/BMP conversion

  - by stanigator

  I have a svg file that I want to convert to jpeg or bmp (or any other image formats). However, all the conversions that I have used on the various online tools yielded very unclear output images. I don't want to use svg as it is very inconvenient. What would be your suggestions to get around that?

• Batch convert divx to iPhone format

  - by Kelsey

  I am looking for free software to do batch conversions of divx video files to iPhone format. I have read the thread: http://superuser.com/questions/5784/looking-to-convert-video-to-iphone-format Handbrake works good for single files but it has very little customization with regards to files names and the batch functionality is not very good (or at least I can't get it to work very easily). Can anyone recommend a good batch converter? A script for Handbrake to do a batch for all in a specific directory would be useful even.

• Removing "Transfer To..." and "Show Converted Files" from uTorrent's context menu

  - by kotekzot

  Under uTorrent version 3.1.3 (and possibly earlier), the context menu has taken on 2 new options, "Transfer To...", for moving a download to a mobile device, and "Show Converted Files", for built-in conversion. I prefer to do all my file management and conversions manually, and the options are, at best, annoying space wasters. In fact, I'm not sure these features are even available outside of uTorrent Plus, which is not something I run. Is it possible to remove them from the context menu?

• Paid service that will bulk convert HTML and text to PDF?

  - by SCS

  We have a repository of documents in HTML and text that we're looking to get into PDF format, but my boss (another developer) feels that writing this portion of the application will detract from the main development that we're doing at the moment. Is anyone aware of any services that will be able to do bulk conversions of these documents to PDF? Any services that will also provide thumbnails for the documents is something we're looking for as well.

• Python bindings for C++ code using OpenCV giving segmentation fault

  - by lightalchemist

  I'm trying to write a python wrapper for some C++ code that make use of OpenCV but I'm having difficulties returning the result, which is a OpenCV C++ Mat object, to the python interpreter. I've looked at OpenCV's source and found the file cv2.cpp which has conversions functions to perform conversions to and fro between PyObject* and OpenCV's Mat. I made use of those conversions functions but got a segmentation fault when I tried to use them. I basically need some suggestions/sample code/online references on how to interface python and C++ code that make use of OpenCV, specifically with the ability to return OpenCV's C++ Mat to the python interpreter or perhaps suggestions on how/where to start investigating the cause of the segmentation fault. Currently I'm using Boost Python to wrap the code. Thanks in advance to any replies. The relevant code: // This is the function that is giving the segmentation fault. PyObject* ABC::doSomething(PyObject* image) { Mat m; pyopencv_to(image, m); // This line gives segmentation fault. // Some code to create cppObj from CPP library that uses OpenCV cv::Mat processedImage = cppObj->align(m); return pyopencv_from(processedImage); } The conversion functions taken from OpenCV's source follows. The conversion code gives segmentation fault at the commented line with "if (!PyArray_Check(o)) ...". static int pyopencv_to(const PyObject* o, Mat& m, const char* name = "<unknown>", bool allowND=true) { if(!o || o == Py_None) { if( !m.data ) m.allocator = &g_numpyAllocator; return true; } if( !PyArray_Check(o) ) // Segmentation fault inside PyArray_Check(o) { failmsg("%s is not a numpy array", name); return false; } int typenum = PyArray_TYPE(o); int type = typenum == NPY_UBYTE ? CV_8U : typenum == NPY_BYTE ? CV_8S : typenum == NPY_USHORT ? CV_16U : typenum == NPY_SHORT ? CV_16S : typenum == NPY_INT || typenum == NPY_LONG ? CV_32S : typenum == NPY_FLOAT ? CV_32F : typenum == NPY_DOUBLE ? CV_64F : -1; if( type < 0 ) { failmsg("%s data type = %d is not supported", name, typenum); return false; } int ndims = PyArray_NDIM(o); if(ndims >= CV_MAX_DIM) { failmsg("%s dimensionality (=%d) is too high", name, ndims); return false; } int size[CV_MAX_DIM+1]; size_t step[CV_MAX_DIM+1], elemsize = CV_ELEM_SIZE1(type); const npy_intp* _sizes = PyArray_DIMS(o); const npy_intp* _strides = PyArray_STRIDES(o); bool transposed = false; for(int i = 0; i < ndims; i++) { size[i] = (int)_sizes[i]; step[i] = (size_t)_strides[i]; } if( ndims == 0 || step[ndims-1] > elemsize ) { size[ndims] = 1; step[ndims] = elemsize; ndims++; } if( ndims >= 2 && step[0] < step[1] ) { std::swap(size[0], size[1]); std::swap(step[0], step[1]); transposed = true; } if( ndims == 3 && size[2] <= CV_CN_MAX && step[1] == elemsize*size[2] ) { ndims--; type |= CV_MAKETYPE(0, size[2]); } if( ndims > 2 && !allowND ) { failmsg("%s has more than 2 dimensions", name); return false; } m = Mat(ndims, size, type, PyArray_DATA(o), step); if( m.data ) { m.refcount = refcountFromPyObject(o); m.addref(); // protect the original numpy array from deallocation // (since Mat destructor will decrement the reference counter) }; m.allocator = &g_numpyAllocator; if( transposed ) { Mat tmp; tmp.allocator = &g_numpyAllocator; transpose(m, tmp); m = tmp; } return true; } static PyObject* pyopencv_from(const Mat& m) { if( !m.data ) Py_RETURN_NONE; Mat temp, *p = (Mat*)&m; if(!p->refcount || p->allocator != &g_numpyAllocator) { temp.allocator = &g_numpyAllocator; m.copyTo(temp); p = &temp; } p->addref(); return pyObjectFromRefcount(p->refcount); } My python test program: import pysomemodule # My python wrapped library. import cv2 def main(): myobj = pysomemodule.ABC("faces.train") # Create python object. This works. image = cv2.imread('61.jpg') processedImage = myobj.doSomething(image) cv2.imshow("test", processedImage) cv2.waitKey() if __name__ == "__main__": main()

• HTML5 mobile game development vs. native game apps

  - by Vic Szpilman

  What is the current state of game engines, frameworks, libraries and conversions related to the HTML5 set of technologies (including CSS3 and JavaScript libraries such as RaphaelJS, Impact, gameQuery); and how does the best of that compare with developing a native app (especially for iOS and Android)? Especially in terms of performance, visuals and getting that "native feel". Thoughts on solutions such as Appcelerator and Corona SDK are also appreciated. In regards to Unity3D, is it possible to develop in it and still have the game be playable on a browser (such as current releases of Chrome or Firefox, at least) without any dependencies or having the user install anything (no unity web player). What I'm looking for is how to develop in web standards as to reach the maximum number of platforms (including outside mobile) while still retaining a native experience for mobile without having to implement the game anew for iOS and Android.

• Historical origins of Scala implicits

  - by Frank

  Scala has been called complex with its rich feature set by many of my colleagues and some even blamed all those new features of it. While most programmers are aware of the OO-features, and at least the decent ones also know about functional programming, there is one feature in particular in Scala for which I am not aware of its historical origins. Given that a major mantra of our profession is to not reinvent the wheel, I am rather confident, that Scala does not have any actual unheard-of-before features, but I stand to be corrected on this one if necessary. To get to the actual question, while I am aware of the origins of most of Scala's features I have never seen something like its implicit declarations before. Are there other (older!) languages out there which also provide this feature? Does it make sense to distinguish the different cases of implicits (as they may originate from different sources), namely implict conversions and implicit parameters?

• Replacing LF, NEL line endings in text file with CR+LF

  - by Tomas Lycken

  I have a text file with a strange character encoding that I'd like to convert to standard UTF-8. I have managed to get part of the way: $ file myfile.txt myfile.txt: Non-ISO extended-ASCII text, with LF, NEL line endings $ iconv -f ascii -t utf-8 myfile.txt > myfile.txt.utf8 $ file myfile.txt.utf8 myfile.txt.utf8: UTF-8 Unicode text, with LF, NEL line endings ## edit myfile.txt.utf8 using nano, to fix failed character conversions (mostly åäö) $ file myfile.txt.utf8 myfile.txt.utf8: UTF-8 Unicode text, with LF, NEL line endings However, I can't figure out how to convert the line endings. How do I do to replace LF+NEL with CR+LF (or whatever is the standard)? When I'm done, I'd like to see the following: $ file myfile.txt myfile.txt: UTF-8 Unicode text

• Javascript naming conventions

  - by ManuPK

  I am from Java background and am new to JavaScript. I have noticed many JavaScript methods using single character parameter names, such as in the following example. doSomething(a,b,c) I don't like it, but a fellow JavaScript developer convinced me that this is done to reduce the file size, noting that JavaScript files have to be transferred to the browser. Then I found myself talking to another developer. He showed me the way that Firefox will truncate variable names to load the page faster. Is this a standard practice for web browsers? What are the best-practice naming conversions that should be followed when programming in JavaScript? Does identifier length matter, and if so, to what extent?

• Using RegEx's in Multi-Channel Funnels in Google Analytics

  - by Rob H

  For some reason, I can't get my multi-channel funnel which utilizes RegEx's in the path steps to function -- it keeps coming back with no data. There are a few variables which may be holding things up, but I can't figure out the origin of the problem, nor a solution. Here's the situation: The funnel is tracking conversions, defined as when a user completes 4 steps to signup Steps are not "required" Default URL is set to https://example.com There is a 302 redirect set up on our site that leads from http://example.com to https://example.com Within the funnel, steps switch from non-secure pages (unless browser is set to secure browsing), to secure pages once the user moves from the landing page to the second page of the sign-up process (account placeholder has been created) URL at that point contains the variable of publisher number within (but not at the end) the URL My RegEx's are all properly written as tested on rubular.com

• Google Analytics Campaigns Not Tracking E-Commerce

  - by Paul

  I am running email campaigns via MailChimp and tracking the success of my campaigns via Google Analytics. I can successfully see data being tracked for: Reporting > Conversions > Ecommerce (Receiving Data) Reporting > Traffic Sources > Campaigns (Receiving Data) However, I am not receiving any Ecommerce data for the individual campaigns: Reporting > Traffic Sources > Campaigns > Ecommerce (No data) So I see data like: Visits: 18,501 Revenue: $0.00 Everything I have read leads me to believe this should just "work" if Ecommerce is setup. Is there some additional action I need to take for this work? Any help would be appreciated!

• How important is to avoid name collisions between libraries belonging to different domains?

  - by Sergio

  I have written a small open source Java library for facilitating conversions between different types of objects (in the style of Google's gson, but quite more general). It seems to me that a nice natural name for my library is JConverter, after browsing in the web to see if another library with the same name already exists, I found a library with the same name for Joomla. My concrete question is: How important is to avoid naming collisions when creating an open source library if an existing library with the chosen name already exists in a complete different domain ? (in my concrete case, these are libraries even implemented for different languages).

• Best in-depth analytics or stats tools? (preferrably server-side)

  - by Litso

  Hey all, I know there's been questions about this before, but mine is a little more specific. I work for a high traffic website and we want to start tracking our visitors better. Unfortunately, Google Analytics is not an option at the moment, so what I'm looking for is some alternatives, preferrably server-side (but not necessarily). We're currently running Urchin, but what I'm missing most there is the way you can set conversions in Analytics and then track (for example) which keywords convert better or which landing pages convert better. Also, A/B testing is something I really miss. Which analytics tools can be compared to analytics in terms of advanced segmentation, navigation summaries, A/B testing, etc?
