• Content Types in browsers, can we use the Mime??

  - by SoLoGHoST

  Ok, I am wondering which mime types are dangerous in browsers? That is to say setting the Content Type to that mime type?? Which mime types, if any would pose a security risk?? I am noticing that many forum software, when uploading files, use the application/octet-stream for any files other than images and place that into the Content Type of the header. I am wondering why don't they place the actual mime-type instead into the Content Type? Are there security risks involved with this? So far I have used text/css, text/plain, audio/mpeg, and many others and haven't noticed any difference between application/octet-stream and these others. Does anyone out there know the exact difference, and what makes application/octet-stream any better, or any worse...to use for the Content Type?? Thank You :)

• Reading html with accented characters from a URL on iPhone

  - by lbh

  Hello, I'm having trouble extracting the html from a website which contains accented characters. Specifically, there are French characters on the site. Currently I'm using: NSString* html= [NSString stringWithContentsOfURL: [NSURL URLWithString: url] usedEncoding: &enc error:&error]; to get html from a URL. It works perfectly fine for any sites which are all English, but with a mostly English site with French characters it returns nothing. I've tried a few different types of encoding, but none have worked for me. Any suggestions? Thanks.

• "Voice trigger" detection

  - by sehugg

  I have a voice application that would be much-improved if there was the ability to use a "trigger word" to start recording audio. I don't need a full speech-text engine, just the ability to reliably/efficiently detect the trigger word. I am wondering if there are any specialized speech engines that support this specific use case, or any libraries/methods to developing such a single-purpose detection engine. Ideally I'd like it to work in noisy environments, but it can be trained for a single user's voice. Pointers to research papers / topics would also be appreciated so I know what to ask for.

• Quickbooks ItemServiceQueryRq not returning all service items

  - by gdx

  I am implementing a billing system for a client. I wrote this XML query to grab all the Item Service Codes from the company file: <?xml version=\"1.0\" encoding=\"utf-8\"?><?qbxml version=\"2.0\"?><QBXML><QBXMLMsgsRq onError=\"continueOnError\"><ItemServiceQueryRq requestID=\"81\"></ItemServiceQueryRq></QBXMLMsgsRq></QBXML> For the life of me I can't get QB web connector to return all of the service codes. The company file has about 500 service codes but it only returns 67. Does anyone have any idea on why this would happen? The QB web connector application log doesn't provide any hints either.

• How to parse JSON string that can be one of two different strongly typed objects?

  - by user852194

  Background: I'm invoking a web service method which returns a JSON string. This string can be of type ASConInfo or ASErrorResponse. Question: Using the DataContractJsonSerializer, how can I convert the returned JSON string to one of those objects? Thanks in advance I have tried the following technique, but it does not work: public static object test(string inputString) { object obj = null; using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(inputString))) { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(object)); obj = ser.ReadObject(ms) as object; } return obj; } [WebMethod] public string TypeChecker() { string str = "{\"Error\":191,\"ID\":\"112345678921212\",\"Length\":15}"; //string strErro = ""; object a = test(str); if (a is ASResponse) { return "ASResponse"; } if (a is ASErrorResponse) { return "ASErrorResponse"; } return "Nothing"; }

• A non-blocking server with java.io

  - by Jon

  Everybody knows that java IO is blocking, and java NIO is non-blocking. In IO you will have to use the thread per client pattern, in NIO you can use one thread for all clients. Now my question follows: is it possible to make a non-blocking design using only the Java IO api. (not NIO) I was thinking about a pattern like this (obviously very simplified); List<Socket> li; for (Socket s : li) { InputStream in = s.getInputStream(); byte[] data = in.available(); in.read(data); // processData(data); (decoding packets, encoding outgoing packets } Also note that the client will always be ready for reading data. What are your opinions on this? Will this be suitable for a server that should at least hold a few hundred of clients without major performance issues?

• iPhone: Try to send html code to a php script (but fail)

  - by Marc-André Weibezahn

  Hello all, I am trying this for an iPhone app in Xcode: create html code for a website on the fly sending it to a php-script and getting the response with this code: NSError * error = [[[NSError alloc]init]autorelease]; NSURL * phpURL = [NSURL URLWithString: @"http://www.mydomain.com/myscript.php?mywebsite= (...websitestring...) ];NSString * myResponse = [NSString stringWithContentsOfURL:phpURL encoding:NSUTF8StringEncoding error:&error]; It does not work. It should not be a problem of the php code because when I replace the websitestring which contains the html code with "hello" or something, this is accepted. (the script then creates a file "test.html" with the content I sent.) But when I put html code in it, I always get the error: Error Domain=NSCocoaErrorDomain Code=256 "The operation couldn’t be completed. (Cocoa error 256.)" UserInfo=0x322ec10 {} It seems that there are some things to consider when sending code to php? Thanks in advance!

• Performance: float to int cast and clippling result to range

  - by durandai

  I'm doing some audio processing with float. The result needs to be converted back to PCM samples, and I noticed that the cast from float to int is surprisingly expensive. Whats furthermore frustrating that I need to clip the result to the range of a short (-32768 to 32767). While I would normally instictively assume that this could be assured by simply casting float to short, this fails miserably in Java, since on the bytecode level it results in F2I followed by I2S. So instead of a simple: int sample = (short) flotVal; I needed to resort to this ugly sequence: int sample = (int) floatVal; if (sample > 32767) { sample = 32767; } else if (sample < -32768) { sample = -32768; } Is there a faster way to do this? (about ~6% of the total runtime seems to be spent on casting, while 6% seem to be not that much at first glance, its astounding when I consider that the processing part involves a good chunk of matrix multiplications and IDCT)

• Load a single symbol from a LaTeX package

  - by Martijn

  When using the MnSymbol package, pdflatex gives two font warnings: LaTeX Font Warning: Encoding 'OMS' has changed to 'U' for symbol font (Font) 'symbols' in the math version 'normal' on input line 120. LaTeX Font Info: Overwriting symbol font 'symbols' in version 'normal' (Font) OMS/cmsy/m/n --> U/MnSymbolF/m/n on input line 120. It turns out that this is probably due to a clash with the AMSSymb package. Since I need just a few symbols from the package: is there a way to load one symbol from a package, in stead of all?

• Loading HTML into a Cocoa app with WebView and change text

  - by Domness

  Right, so far I've got this for loading up a HTML file from within my app: NSString *path1 = [[NSBundle mainBundle] pathForResource:@"file" ofType:@"html"]; NSString *html = [NSString stringWithContentsOfFile:path1 encoding:NSUTF8StringEncoding error:nil]; [[webView mainFrame] loadHTMLString:html baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]bundlePath]]]; Which works loading the file up into the app's WebView. But I want to change some values in the HTML (or PHP if it works by using $_REQUEST/$_GET), for example, I have a table with some text in it and I want to change this text from an NSString etc. How would I go about this?

• Is there a way to highlight specific words or numbers without inserting a span tag?

  - by Taylor

  I've got blocks of text with various specs in them and want to have jquery highlight whatever matches a specific pattern without inserting any extra html. The following is the kind of text that I've got to work with. Intel® Core™ i7 Processor 920 (2.66GHz, 8MB cache, 4.8GT/sec)/ Genuine Windows® 7 Home Premium 64bit- English/ 640 GB Serial ATA non Raid (7200 Rpm)/ 6GB 1333MHz (3x2GB) Tri Channel Memory/ Display Not Included/ 16X DVD+/- RW Optical Drive (DVD & CD read and write)/ 1.8GB NVIDIA® GeForce™ GTX260 graphics card/ Integrated HDA 7.1 Dolby Digital Audio What I'm hoping jquery can do is highlight some of the basic specs without inserting any extra html. Maybe working off a list of values matching the spec format using some wildcards where neededed? The css to select the correct tag is #list div div div+p or I could just give the p class but would rather not. Is this kind of thing possible?

• UIWebView load remote html page with local images and javascript files

  - by BlueNile

  Im creating application that will display remote page on the UIWebView using local images and javascript/css files for faster loading. I want to avoid using cache because for this to work it must first load all the content. I was searching online for possible solution. Here is what I have: NSURLRequest *urlrequest = [ [NSURLRequest alloc] initWithURL: [NSURL URLWithString:urlString] ]; NSData *returnData = [ NSURLConnection sendSynchronousRequest:urlrequest returningResponse: nil error: nil ]; NSString *HTMLData = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSString *resourcePath = [[NSBundle mainBundle] resourcePath]; resourcePath = [resourcePath stringByReplacingOccurrencesOfString:@"/" withString:@"//"]; resourcePath = [resourcePath stringByReplacingOccurrencesOfString:@" " withString:@"%20"]; [webView loadHTMLString:HTMLData baseURL: [NSURL URLWithString: [NSString stringWithFormat:@"file:/%@//",resourcePath] ]]; urlString is defined and I moved files to the app bundle. Code works as I can see the remote page but no images nor javascript files are present.

• Print unique ascii characters in eclipse console

  - by Shaded

  Hey guys, Kind of a strange question but... here it goes. Recently my application threw an IOException that the text only had a clubs symbol in it (like the suit in cards) I know this is probably because there was a number in there that was cast to a char and printed to the screen, and I've found where that might have happened. The only problem is, I can't recreate it in eclipse because the eclipse console doesn't want to print those characters for me. All I get are boxes. I figure this is an encoding issue or something but I need eclipse to print out those characters just like the windows console would. Is there a setting I can change to do this?

• File encodings with ruby

  - by pablorc

  Hi, I'm having a bit problems with file encodings. I'm receiving a url-encoded string like "sometext%C3%B3+more+%26+andmore", unescape it, process the data, and save it with windows-1252 encoding. The conversions are these: irb(main) >> value => "sometext%C3%B3+more+%26+andmore" irb(main) >> CGI::unescape(value) => "sometext\303\263 more & andmore" irb(main) >> #Some code and saved into a file using open(filename, "w:WINDOWS-1252") irb(main) >> # result in the file: => sometextA³ more & andmore And the result should be sometextó more & andmore

• How can I configure a Hudson job to use a specific JDK?

  - by rewbs

  I have a number of projects running on a Hudson slave. I'd like one of them to run Ant under Java6, rather than the default (which is Java5 in my environment). In the project configuration view, I was hoping to find either: An explicit option allowing me to set a custom JDK location to use for this project. A way to set custom environment variables for this project, which would allow me to set JAVA_HOME to the JDK6 location. The would make Ant pick up and run on Java6 as desired. Is there a way to do either of the above? If one of those facilities is available, I can't see how to access it. I'm running on Hudson 1.285. I would rather avoid using an "execute shell" operation instead of the "invoke Ant" operation if possible: my slave is on z/OS and Hudson doesn't seem to create the temporary shell scripts properly on this platform (probably an encoding issue).

• Securely using exec with PHP to run ffmpeg

  - by Venkat D.

  I would like to run ffmpeg from PHP for video encoding purposes. I was thinking of using the exec or passthru commands. However, I have been warned that enabling these functions is a security risk. In the words of my support staff: The directive 'disable_functions' is used to disable any functions that allow the execution of system commands. This is for more security of the server. These PHP functions can be used to crack the server if not used properly. I'm guessing that if exec is enabled, then someone could (possibly) execute an arbitrary unix command. Does anyone know of a secure way to run ffmpeg from PHP? By the way, I'm on a dedicated server. Thanks ahead of time!
