  • Programming language detection in PHP

    - by nandu
    I need to detect which programming language is used in a code snippet, there is any library to do this? I already read this http://stackoverflow.com/questions/475033/detecting-programming-language-from-a-snippe, but I rather use a tested and working library.

  • Audio Detection in Matlab

    - by insane-36
    I am writing a matlab code that would be able to read the audio file and then compare it to the another audio and recognize if those audio are the voice of the same person. In both type of the audio, would have the same word utterance and the audio is about 1 minutes long. I have come to know that the approach of sliding windows using hamming window would work best on this approach but have a very little idea on this. The simple code to read an audio file and then display a portion of 10s is as below : [x,fs, nbits]= wavread('01-AudioTrack 01.wav'); subplot(211) plot(x) title('Entire Wave') smallRange = 1:100000; subplot(212) plot(smallRange,x(smallRange)) How do I make Hamming window each of 10ms in this case and what approaches should I take to deal with this problem ?

  • Customizing detection change

    - by mada
    Hi, I can now if a session contain any changes which must be synchronized with the database with session.isDirty() But i have a simple field (modification date) that i would like to be ignore by it. Example: object Person( name,age,datemodification). if i just modify the datemodification field i would like that session.isDirty() or othermethod like this to return false so at the end no sql update will occur. Thanks in advance. Regards

  • Flag bit computation and detection

    - by Majid
    Hi all, In some code I'm working on I should take care of ten independent parameters which can take one of two values (0 or 1). This creates 2^10 distinct conditions. Some of the conditions never occur and can be left out, but those which do occur are still A LOT and making a switch to handle all cases is insane. I want to use 10 if statements instead of a huge switch. For this I know I should use flag bits, or rather flag bytes as the language is javascript and its easier to work with a 10 byte string with to represent a 10-bit binary. Now, my problem is, I don't know how to implement this. I have seen this used in APIs where multiple-selectable options are exposed with numbers 1, 2, 4, 8, ... , n^(n-1) which are decimal equivalents of 1, 10, 100, 1000, etc. in binary. So if we make call like bar = foo(7), bar will be an object with whatever options the three rightmost flags enable. I can convert the decimal number into binary and in each if statement check to see if the corresponding digit is set or not. But I wonder, is there a way to determine the n-th digit of a decimal number is zero or one in binary form, without actually doing the conversion?

  • Does CSS have a "start over" feature?

    - by Rick Wayne
    I'm using calendar_date_select (henceforth CDS) in a Rails application, and have a stupid question. When I embed the CDS component in the middle of an already-CSS-styled page, all manner of things go ugly-wrong with it (spacing, fonts, etc.). Clearly the elements inside the CDS have inherited unwanted stuff from the styles already working in the containing page. Now, I could use a combination of, say, Safari's CSS debugging and analyze what's wrong element-by-element. But that's (A) tedious, and (B) might load up my component's styles with tons of container-defeating special cases. If nothing else, I'm certain to change the containing page's styles in the future and would have to maintain the special cases. My question: Is is possible to have a DIV in a page that essentially backs out all the existing styling? Is there a simple one-liner that will do this? Failing that, can it be done on an element-by-element basis? E.g. I know what tags the CDS generates, so I could list each of them: { p: "#--NOTHING--#"; a: "#--NOTHING--#"; } where #--NOTHING--# is the Magic Turn Off All Inherited Styles incantation. http://code.google.com/p/calendardateselect/ Thanks, peeps.

  • Visual studio feature - commenting code Ctrl K - Ctrl C

    - by Michael
    I commented on this answer some time ago regarding how visual studio comments out code with // or /* */. I was thinking to revise the answer (to include my findings) but I had to test it first, which kind of confused me. My finding is that depending on where your marker is when you press Ctrl - K, Ctrl - C you will get either // or /* */. So I tried it out on the following code: [1] [2]FD_ZERO(&mFSet); FD_SET(user->mSender, &mFSet); timeval zeroTime = { 0, 0 }; int sel = select(0, NULL, &mFSet, NULL, &zeroTime); [3] if (sel == SOCKET_ERROR){ [5]return false; [4] } if (sel == 0){ [6] return false; [7] } The [x] is markerpositions. All [1] positions give // for all marked lines. However Start position End Position: gives: [2] [3] : /* */ [2] [4] : // [2] [5] : /* */ [2] [more than 5] : // [5] [6] : /* */ [5] [7] : // I guess it has to do with forward indentation (not backwards), that whenever code is indented more than the starting line you get // except when you haven't selected any text on the indented line ([2] [5]). But why the distinction? Why not use /* */ for when you start at [2] and // when you start at [1]?

  • Implementing a 'Send Feedback' feature in a Java desktop application

    - by William
    I would like to implement a 'Send Feedback' option in a Java desktop application. One which will pop up a box for the user to enter a comment, then send it to us along with a screenshot of the application window. How would be the best way to communicate the data to us? Two obvious solutions spring to mind: Email - I'm thinking that the application would connect to an SMTP server set-up by us, with the username/password somehow hidden in the code. SMTP over SSL for security (not of the data being sent, but of the SMTP username/password). Web service - pretty self explanatory. Which of these would be best, or is there a better alternative?

  • CSS overflow detection in JavaScript

    - by ring0
    In order to display a line of text (like in a forum), and end that line with "..." if the text would overflow the line (not truncating using the CSS overflow property), there are a number of ways. I'm still seeking the best solution. For instance, Adding in CSS a "..." as a background-image is a possibility, but it would appear all the time, and this is not a good solution. Some sites just count the characters and if over - say - 100, truncates the string to keep only 100 (or 97) chars and add a "..." at the end. But fonts are usually not proportional, so the result is not pretty. For instance the space - in pixels - taken by "AAA" and "iii" is clearly different "AAA" and "iii" via a proportional font have the same width There is another idea to get the exact size in pixels of the string: create in Javascript a DIV insert the text in it (via innerHTML for instance) measure the width (via .offsetWidth) which is not implemented yet. However, I wonder if there could be any browser compatibility problem? Did any one tried this solution? Other recommendations would be welcome.

  • java string detection of ip

    - by user384706
    Hi, Assume a java string that contains an IP (v4 or v6) or a hostname. What is the best way to detect among these cases? I am not interested so much on whether the IP is in valid range (e.g. 999.999.999.999 for IPv4). I am interested in just a way to detect if a String is a hostname or an IP (v4 or v6). Initially I though this: if(theString.indexOf("@")!=-1){ //Not an Ip } but I am not sure if I should always expect a format containing @ always. Thanks

  • Detection of negative integers using bit operations

    - by Nawaz
    One approach to check if a given integer is negative or not, could be this: (using bit operations) int num_bits = sizeof(int) * 8; //assuming 8 bits per byte! int sign_bit = given_int & (1 << (num_bits-1)); //sign_bit is either 1 or 0 if ( sign_bit ) { cout << "given integer is negative"<<endl; } else { cout << "given integer is positive"<<endl; } The problem with this solution is that number of bits per byte couldn't be 8, it could be 9,10, 11 even 16 or 40 bits per byte. Byte doesn't necessarily mean 8 bits! Anyway, this problem can be easily fixed by writing, //CHAR_BIT is defined in limits.h int num_bits = sizeof(int) * CHAR_BIT; //no assumption. It seems fine now. But is it really? Is this Standard conformant? What if the negative integer is not represented as 2's complement? What if it's representation in a binary numeration system that doesn't necessitate only negative integers to have 1 in it's most significant bit? Can we write such code that will be both portable and standard conformant? Related topics: Size of Primitive data types Why is a boolean 1 byte and not 1 bit of size?

  • How to visualize Feature branches?

    - by crauscher
    We are using separate branches for separate features and we need to visualize these brances. Is there a tool that can help us? We do not need a tool that uses our source-repository to generate the graph. We want to use the tool for planning new branches and for visalizing them.

  • C# IE Proxy Detection not working from a Windows Service

    - by mytwocents
    This is very odd. I've written a windows form tool in C# to return the default IE proxy. It works (See code snippets below). I've created a service to return the proxy using the same code, it works when I step into the debugger, BUT it doesn't work when the service is running as binary code. This must be some sort of permissions or context thing that I cannot recreate. Further, if I call the tool from the windows service, it still doesn't return the proxy information.... this seems isolated to the service somehow. I don't see any permission errors in the events log, it's as if a service has a totally different context than a regular windows form exe. I've tride both: WebRequest.GetSystemWebProxy() and Uri requestUri = new Uri(urlOfDomain); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestUri); IWebProxy proxy = request.Proxy; if (!proxy.IsBypassed(requestUri)){ Uri uri2 = proxy.GetProxy(request.RequestUri); } Thanks for any help!

  • highlight query string in more than one field using solr search feature

    - by Romi
    i am using solr indexes for showing my search results. to show serch results i am parsing json data received from solr. i am able to highlight a query string in search result but only in a single field. for this i set hl=true and hl.fl="field1". i did it as $.getJSON("http://192.168.1.9:8983/solr/db/select/?wt=json&&start=0&rows=100&q="+lowerCaseQuery+"&hl=true&hl.fl=description,name&hl.usePhraseHighlighter=true&sort=price asc&json.wrf=?", function(result){ var n=result.response.numFound var highlight = new Array(n); $.each(result.highlighting, function(i, hitem){ var match = hitem.text[0].match(/<em>(.*?)<\/em>/); highlight[i]=match[1]; }); $.each(newresult.response.docs, function(i,item){ var word=highlight[item["UID_PK"]]; var result = item.text[0].replace(new RegExp(word,'g'), '<em>' + word + '</em>'); }); for this json object is as : { "responseHeader": { "status": 0, "QTime": 32 }, "response": { "numFound": 21, "start": 0, "docs": [ { "description": "The matte finish waves on this wedding band contrast with the high polish borders. This sharp and elegant design was finely crafted in Japan.", "UID_PK": "8252", }, { "description": "This elegant ring has an Akoya cultured pearl with a band of bezel-set round diamonds making it perfect for her to wear to work or the night out.", "UID_PK": "8142", }, ] }, "highlighting": { "8252": { "description": [ " and <em>elegant</em> design was finely crafted in Japan." ] }, "8142": { "description": [ "This <em>elegant</em> ring has an Akoya cultured pearl with a band of bezel-set round diamonds making" ] }, } } Now if i want to highlight query string in two fields i did as hl=true hl.fl=descrption, name my json is as: { "responseHeader":{ "status":0, "QTime":16 }, "response":{ "numFound":1904, "start":0, "docs":[ { "description":"", "UID_PK":"7780", "name":[ "Diamond bracelet with Milgrain Bezel1" ] }, { "description":"This pendant is sure to win hearts. Round diamonds form a simple and graceful line.", "UID_PK":"8121", "name":[ "Heartline Diamond Pendant" ] }, "highlighting":{ "7780":{ "name":[ "<em>Diamond</em> bracelet with Milgrain Bezel1" ] }, "8121":{ "description":[ "This pendant is sure to win hearts. Round <em>diamonds</em> form a simple and graceful line." ], "name":[ "Heartline <em>Diamond</em> Pendant" ] } } } Now how should i parse it to get the result. suggest me some general technique, so if i want to highlight query in more fields then i could do so. Thanks

  • What do you call this functional language feature?

    - by Jimmy
    ok, embarrassing enough, I posted code that I need explained. Specifically, it first chains absolute value and subtraction together, then tacks on a sort, all the while not having to mention parameters and arguments at all, because of the presense of "adverbs" that can join these functions "verbs" What (non-APL-type) languages support this kind of no-arguments function composition (I have the vague idea it ties in strongly to the concepts of monad/dyad and rank, but its hard to get a particularly easy-to-understand picture just from reading Wikipedia) and what do I call this concept?

  • Questions regarding PHPUnit mock feature

    - by Andree
    Can someone provide me a reference to a good PHPUnit mock guide? The one in the official documentation doesn't seem to be detailed enough. I need to know about the following: 1) How to expect multiple calls to a mock object's method, but each return a different sets of value? $tableMock->expects($this->exactly(2)) ->method('find') ->will($this->returnValue(2)); // I need the second call to return different value 2) How to expect a call to a mock object's method with multiple parameters?

  • Vote based issue tracking and feature request system? [closed]

    - by meds
    I'd like a system where people can sign up and post bugs or feature requests they might have and have access to seeing other bugs and feature requests they can vote on based on which they want the most. Something like http://feedback.unity3d.com would be great. edit: I'm not exactly sure how this isn't 'a real question', perhaps people are incapable of inferring a question because of a lack of a question mark so here's one: '?' is that better? (that makes two).

  • Connection Timeout Extension/Detection

    - by ircmaxell
    Well, let me start off by explaining what I'm trying to do. I have an application that stalls a HTTP connection until new data is available (sometimes a few seconds, sometimes 30 minutes or so). Right now, the system works fine if the data is sent within a few minutes. The problem I'm facing, is that it doesn't seem that XHR recognizes a dropped connection... So instead of killing the current connection and reconnecting when it detects a dropped connection, it just sits there. I'd really not like to have it force-reconnect every minute or two (That's one reason this app was written, to stop the need for polling). So, my questions are as follows: Is there a way to detect a dropped (not closed) TCP connection with XHR? Is there a way that I can tell XHR not to timeout (I saw IE8 has the .timeout property) Would it be better to send a header (or some other content) every now and then (say once per minute) down the pipe to keep the connection open? Thanks.

  • Hit detection on non-transparent pixel

    - by Abie
    Given a PNG in a web context with some transparent pixels and some non-transparent pixels, is there a way in Javascript to determine if a user has clicked on a non-transparent pixel? A webkit-only solution would be perfectly acceptable.

  • Community "Groups" feature (Ruby on Rails)

    - by timstepp
    Are there any good examples/plugins that enable users to create groups within a community application. For example, I would like to create a Group class and add it to something like Community Engine (http://communityengine.org/). Essentially, users need to be able to create and manage groups that other users can join (much like Facebook Pages). Thanks!
