  • Read data from ATOM file with jquery.

    - by carrerasrodrigo
    Hi, i'm trying to read a xml/atom file, the code is: $.ajax({ type: 'GET', url: options.url, data: options.data, dataType: 'xml', async:options.async, success: function(xml) { var feed = new JFeed(xml); if(jQuery.isFunction(options.success)) options.success(feed); } }); The atom file has a field like this: <entry> <content type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml">Docentes y alumnos desa...</div> </content> </entry> The code to read the content tag is: jQuery(this).find('content').eq(0).text(); this - the entry part. The problem is, when jQuery execute this line returns "Docentes y alumnos desa...". There is is a way that jQuery returns---- "<div xmlns="http://www.w3.org/1999/xhtml">Docentes y alumnos desa...</div>" Thanks!! and sorry for the english!!

  • Card emulation via software NFC

    - by user85030
    After reading a lot of questions, i decided to post this one. I read that stock version of android does not support API's for card emulation. Also, we cannot write custom applications to secure element embedded in nfc controllers due to keys managed by google/samsung. I need to emulate a card (mifare or desfire etc). The option i can see is doing it via software. I have a ACR122U reader and i've tested that NFC P2P mode works fine with the Nexus-S that i have. 1) I came across a site that said that nexus s's NFC controller (pn532) can emulate a mifare 4k card. If this is true, can i write/read apdu commands to this emulated card? (Probably if i use a modded rom like cyanogenmod) 2) Can i write a android application that reads apdu commands sent from the reader and generate appropriate responses (if not fully, then upto some extent only). To do so, i searched that we need to patch nexus s with cynagenmod. Has someone tried emulating card via this method? I see that this is possible since we have products from access control companies offering mobile applications via which one can open doors e.g. http://www.assaabloy.com/en/com/Products/seos-mobile-access/

  • Android: Cannot get the httpPost params but can get the httpGet from php

    - by jjLin
    Here is my android code to send request: // defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(serverUrl); List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("abc", "abc2")); httpPost.setEntity(new UrlEncodedFormEntity(params)); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); InputStream is = null; is = httpEntity.getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader( is, "UTF-8"), 8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); String json = ""; json = sb.toString(); Log.d("JSON", "JSON is:" + json); and here is my php code to get the request: <?php echo $_POST['abc']; ?> When I run the application, the string json is nothing. I expect to get JSON is:abc2 Then I change the some code, in android part: HttpPost httpPost = new HttpPost(serverUrl); change to: HttpPost httpPost = new HttpPost(serverUrl + "?abc=abc3"); in php part: <?php echo $_GET['abc']; ?> This time, the string json in logcat is JSON is:abc3. It is correct!! I have tried lots of time, but seems cannot send HttpPost request with params. Any one can help me to find out what wrongs with my code??

  • Wireshark Dissector: How to Identify Missing UDP Frames?

    - by John Dibling
    How do you identify missing UDP frames in a custom Wireshark dissector? I have written a custom dissector for the CQS feed (reference page). One of our servers gaps when receiving this feed. According to Wireshark, some UDP frames are never received. I know that the frames were sent because all of our other servers are gap-free. A CQS frame consists of multiple messages, each having its own sequence number. My custom dissector provides the following data to Wireshark: cqs.frame_gaps - the number of gaps within a UDP frame (always zero) cqs.frame_first_seq - the first sequence number in a UDP frame cqs.frame_expected_seq - the first sequence number expected in the next UDP frame cqs.frame_msg_count - the number of messages in this UDP frame And I am displaying each of these values in custom columns, as shown in this screenshot: I tried adding code to my dissector that simply saves the last-processed sequence number (as a local static), and flags gaps when the dissector processes a frame where current_sequence != (previous_sequence + 1). This did not work because the dissector can be called in random-access order, depending on where you click in the GUI. So you could process frame 10, then frame 15, then frame 11, etc. Is there any way for my dissector to know if the frame that came before it (or the frame that follows) is missing? The dissector is written in C. (See also a companion post on serverfault.com)

  • Java split giving opposite order of arabic characters

    - by MuhammadA
    I am splitting the following string using \\| in java (android) using the IntelliJ 12 IDE. Everything is fine except the last part, somehow the split picks them up in the opposite order : As you can see the real positioning 34,35,36 is correct and according to the string, but when it gets picked out into split part no 5 its in the wrong order, 36,35,34 ... Any way I can get them to be in the right order? My Code: public ArrayList<Book> getBooksFromDatFile(Context context, String fileName) { ArrayList<Book> books = new ArrayList<Book>(); try { // load csv from assets InputStream is = context.getAssets().open(fileName); try { BufferedReader reader = new BufferedReader(new InputStreamReader(is)); String line; while ((line = reader.readLine()) != null) { String[] RowData = line.split("\\|"); books.add(new Book(RowData[0], RowData[1], RowData[2], RowData[3], RowData[4], RowData[5])); } } catch (IOException ex) { Log.e(TAG, "Error parsing csv file!"); } finally { try { is.close(); } catch (IOException e) { Log.e(TAG, "Error closing input stream!"); } } } catch (IOException ex) { Log.e(TAG, "Error reading .dat file from assets!"); } return books; }

  • Convert XML to DataSet with rows

    - by lidermin
    Hi, I have an xml file like this: <result> <customer> <id>1</id> <name>A</name> </customer> <customer> <id>2</id> <name>B</name> </customer> </result> So I need that data filled on a DataSet, here is my code: var reader = new StringReader(xmldoc.InnerXml); dsDatos.ReadXml(reader); The problem is that it's filling the dataset with two Tables each one with a single row. But I need a single Table with the two rows. What am I doing wrong? PD: I'm using C# and I don't want to iterate through the XML file, I want to use the ReadXml method. Thanks for your time.

  • Adding multiple rss feeds to a script in SCALA InfoChannel Designer 5

    - by godleuf
    Okay, since it is impossible to talk to anyone on the phone or get support through Scala's "forum", I am going to take a shot and see if anyone out there is feeling my pain. I have a client that uses Scala's InfoChannel Designer and Content Manager. I have had to learn this software from scratch and I have to say it hasn't been easy. I think I am at a point where the overall design is set, but I need to implement a couple of things before I can make this happen. RSS feeds are my issue at this point. Multiple RSS feeds to be specific. I need a feed coming in for 3 areas of content: Wiki News (or equivalent), local weather and a stock ticker. I have learned how to setup a "crawl" using a script example available from Scala's file center and copying and pasting into my design. But from what I have learned first hand and through reading through other forums, you can not have a feed from 3 different sources or urls happening simultaneously. Doesn't seem like it would be an issue, but apparently it is. This small step has held up this project for far too long and I need to get it figured out. This doesn't even touch on my issue of feeding in streaming video as a background but I have gone over this in another question but with no luck thus far. If there is ANYONE out there who is in anything similar using this software, your feedback and/or suggestions would be greatly appreciated. Thanks you for allowing me to vent!

  • Atomic int writes on file

    - by Waneck
    Hello! I'm writing an application that will have to be able to handle many concurrent accesses to it, either by threads as by processes. So no mutex'es or locks should be applied to this. To make the use of locks go down to a minimum, I'm designing for the file to be "append-only", so all data is first appended to disk, and then the address pointing to the info it has updated, is changed to refer to the new one. So I will need to implement a small lock system only to change this one int so it refers to the new address. How is the best way to do it? I was thinking about maybe putting a flag before the address, that when it's set, the readers will use a spin lock until it's released. But I'm afraid that it isn't at all atomic, is it? e.g. a reader reads the flag, and it is unset on the same time, a writer writes the flag and changes the value of the int the reader may read an inconsistent value! I'm looking for locking techniques but all I find is either for thread locking techniques, or to lock an entire file, not fields. Is it not possible to do this? How do append-only databases handle this? Thanks! Cauê

  • Facebook Open Graph - post to all approved users feeds.

    - by simnom
    Hi, I'm struggling to get to grips with posting a feed item to all the members of an approved application. Within the application settings for the user it is stating that the application has permission to post to the wall but I can only achieve this if that user is currently logged in to facebook. Obviously I would like this to function so that any items I uploaded are posted to all the members of the application at any one time. I am using the Facebook PHP SDK from http://github.com/facebook/php-sdk/ and currrently my code is as follows: require 'src/facebook.php'; //Generates access token for this transaction $accessToken = file_get_contents("https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=MyAppId&client_secret=MySecret"); //Gets the full user details as an object $contents = json_decode(file_get_contents("https://graph.facebook.com/SomeUserId?scope=publish_stream&" . $accessToken)); print_r($contents); if ($facebook->api('/' . $contents->id . '/feed', 'POST', array( 'title' => 'New and Improved, etc - 12/03/2010', 'link' => 'http://www.ib3.co.uk/news/2010/03/12/new-and-improved--etc', 'picture' => 'http://www.ib3.co.uk/userfiles/image/etc-booking.jpg', 'scope' => 'publish_stream' ) )==TRUE) { echo "message posted"; } else { echo "message failed"; } The output from $contents shows the expected user details but nothing relating to the permissions for my application. Am I missing a trick here? Then using the $facebook-api() function I am receiving a #200 - Permissions error. The application does not have permission to perform this action. This is driving me a little potty as I suspect I'm missing something straightforward with the authorisation but what? Many thanks in advance for an assistance offered.

  • Can I cross compile with gcc for an old version of a Linux distro on my Ubuntu 9.10?

    - by Johan
    Hi, I have some old hardware with an old version of say SuSE linux running on it. Now I have this fancy development machine running Ubuntu 9.10. Some of the tools I use to compile my C app (written in Python 2.6.x) are not available on the old SuSe box. So... is it possible to compile for that old machine on my dev box? I have the following steps in mind, but would like to cross-check before venturing off into this quest: 1. Find out which static/shared libs my app needs and find/build target version of them 2. Also find the corresponding header files 3. Feed the correct flags to gcc to use the target headers and libraries 4. Feed the correct flags to gcc to use the correct architecture (i386/i686), or do I need a cross-compilation toolchain. 5. Compile, upload and enjoy ;-) I regularly use avr-gcc and cc65, both are cross compiling. I know that you set up a coss compiler for developing something like a gumstix, so it should be possible to do the same for old/other Linux distros, not? C

  • How do I create a python module from a fortran program with f2py?

    - by Lars Hellemo
    I am trying to read some smps files with python, and found a fortran implementation, so I thought I would give f2py a shot. The problem is that I have no experience with fortran. I have successfully installed gfortran and f2py on my Linux box and ran the example on thew f2py page, but I have some trouble compiling and running the large program. There are two files, one with a file reader wrapper and one with all the logic. They seem to call each other, but when I compile and link or try f2py, I get errors that they somehow can't find each other: f95 -c FILEWR~1.F f95 -c SMPSREAD.F90 f95 -o smpsread SMPSREAD.o FILEWR~1.o FILEWR~1.o In function `file_wrapper_' FILEWR~1.F(.text+0x3d) undefined reference to `chopen_' usrlibgcci486-linux-gnu4.4.1libgfortranbegin.a(fmain.o) In function `main' (.text+0x27) undefined reference to `MAIN__' collect2 ld returned 1 exit status I also tried changing the name to FILE_WRAPPER.F but that did not help. With f2py I found out I had to include a comment to get it to accept free format, and saved this as a new file and tried: f2py -c -m smpsread smpsread.f90 I get a lot of output and warnings, but the error seems to be this one: getctype: No C-type found in "{'typespec': 'type', 'attrspec': ['allocatable'], 'typename': 'node', 'dimension': [':']}", assuming void. The fortran 90 spms reader can be found here. Any help or suggestions appreciated.

  • Getting table schema from a query

    - by Appu
    As per MSDN, SqlDataReader.GetSchemaTable returns column metadata for the query executed. I am wondering is there a similar method that will give table metadata for the given query? I mean what tables are involved and what aliases it has got. In my application, I get the query and I need to append the where clause programically. Using GetSchemaTable(), I can get the column metadata and the table it belongs to. But even though table has aliases, it still return the real table name. Is there a way to get the aliase name for that table? Following code shows getting the column metadata. const string connectionString = "your_connection_string"; string sql = "select c.id as s,c.firstname from contact as c"; using(SqlConnection connection = new SqlConnection(connectionString)) using(SqlCommand command = new SqlCommand(sql, connection)) { connection.Open(); SqlDataReader reader = command.ExecuteReader(CommandBehavior.KeyInfo); DataTable schema = reader.GetSchemaTable(); foreach (DataRow row in schema.Rows) { foreach (DataColumn column in schema.Columns) { Console.WriteLine(column.ColumnName + " = " + row[column]); } Console.WriteLine("----------------------------------------"); } Console.Read(); } This will give me details of columns correctly. But when I see BaseTableName for column Id, it is giving contact rather than the alias name c. Is there any way to get the table schema and aliases from a query like the above? Any help would be great!

  • .net real time stream processing - needed huge and fast RAM buffer

    - by mack369
    The application I'm developing communicates with an digital audio device, which is capable of sending 24 different voice streams at the same time. The device is connected via USB, using FTDI device (serial port emulator) and D2XX Drivers (basic COM driver is to slow to handle transfer of 4.5Mbit). Basically the application consist of 3 threads: Main thread - GUI, control, ect. Bus reader - in this thread data is continuously read from the device and saved to a file buffer (there is no logic in this thread) Data interpreter - this thread reads the data from file buffer, converts to samples, does simple sample processing and saves the samples to separate wav files. The reason why I used file buffer is that I wanted to be sure that I won't loose any samples. The application doesn't use recording all the time, so I've chosen this solution because it was safe. The application works fine, except that buffered wave file generator is pretty slow. For 24 parallel records of 1 minute, it takes about 4 minutes to complete the recording. I'm pretty sure that eliminating the use of hard drive in this process will increase the speed much. The second problem is that the file buffer is really heavy for long records and I can't clean this up until the end of data processing (it would slow down the process even more). For RAM buffer I need at lest 1GB to make it work properly. What is the best way to allocate such a big amount of memory in .NET? I'm going to use this memory in 2 threads so a fast synchronization mechanism needed. I'm thinking about a cycle buffer: one big array, the Bus Reader saves the data, the Data Interpreter reads it. What do you think about it? [edit] Now for buffering I'm using classes BinaryReader and BinaryWriter based on a file.

  • Using Array Controllers to restrict the view in one popup depending on the selection in another. Not

    - by mjohnh
    I am working on an app that is not core data based - the data feed is a series of web services. Two arrays are created from the data feed. The first holds season data, each array object being an NSDictionary. Two of the NSDictionary entries hold the data to be displayed in the popup ('seasonName') and an id ('seasonID') that acts as a pointer (in an external table) by matches defined for that season. The second array is also a collection of NSDictionaries. Two of the entries hold the data to be displayed in the popup ('matchDescription') and the id ('matchSeasonId') that points to the seasonId defined in the NSDictionaries in first array. I have two NSPopUps. I want the first to display the season names and the second to display the matches defined for that season, depending on the selection in the first. I'm new at bindings, so excuse me if I've missed something obvious. I've tried using ArrayControllers as follows: SeasonsArrayController: content bound to appDelegate seasonsPopUpArrayData. seasonsPopup: content bound to SeasonsArrayController.arrangedObjects; content value bound to SeasonsArrayController.arrangedObjects.seasonName I see the season names fine. I can obviously follow a similar route to see the matches, but I then see them all, instead of restricting the list to the matches for the season highlighted. All the tutorials I can find seem to revolve around core data and utilise the relationships defined therein. I don't have that luxury here. Any help very gratefully received.

  • Is it possible to prevent out-of-order execution by using single volatile

    - by Yan Cheng CHEOK
    By referring article, it is using a pair of volatile to prevent out-of-order execution. I was wondering, is it possible to prevent it using single volatile? void fun_by_thread_1() { this.isNuclearFactory = true; this.factory = new NuclearFactory(); } void fun_by_thread_2() { Factory _factory = this.factory; if (this.isNuclearFactory) { // Do not operate nuclear factory!!! return; } // If out-of-order execution happens, _factory might // be NuclearFactory instance. _factory.operate(); } Factory factory = new FoodFactory(); volatile boolean isNuclearFactory = false; The reason I ask, is because I have a single guard flag (similar to isNuclearFactory flag), to guard against multiple variables (similar to many Factory). I do not wish to mark all the Factory as volatile. Or, shall I fall into the following solution? void fun_by_thread_1() { try { writer.lock(); this.isNuclearFactory = true; this.factory = new NuclearFactory(); } finally { writer.unlock(); } } void fun_by_thread_2() { try { reader.lock(); Factory _factory = this.factory; if (this.isNuclearFactory) { // Do not operate nuclear factory!!! return; } } finally { reader.unlock(); } _factory.operate(); } Factory factory = new FoodFactory(); boolean isNuclearFactory = false; P/S: I know instanceof. Factory is just an example to demonstrate of out-of-order problem.

  • What programming language is this?

    - by Richard M.
    I recently stumbled over a very odd source listing on a rather old programming-related site (lost it somewhere in my browser history as I didn't care about it at first). I think that this is part of a simple (console-based?) snake game. I searched and searched but didn't find a language that looked somwhat like this. This seems like a mix of Python, Ruby and C++. What the hell? What programming-language is the below source listing written in? Maybe you can figure it out? my Snake.hasProps { length parts xDir yDir } & hasMethods { init: length = 0 parts[0].x,y = 5 move: parts[ 0 ].x,y.!add xDir | yDir # Move the head map parts(i,v): parts[ i ] = parts[ i + 1 ] checkBiteSelf checkFeed checkBiteSelf: part } my SnakePart.hasProps { x y } fork SnakePart to !Feed my Game.hasProps { frameTime = 30 } & hasMethods { init: mainloop mainloop: sys.util.sleep frameTime Snake.move Field.getInput -> Snake.xDir | Snake.yDir Field.reDraw with Snake & Feed & Game # For FPS } main.isMethod { game.init }

  • Convert InputStream to String with encoding given in stream data

    - by Quentin
    Hi, My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document. From this InputStream, I want to have all document in a String. To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding. It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error. Any idea, how to do it ? public static String streamToString(final InputStream is) { String result = null; if (is != null) { BufferedInputStream bis = new BufferedInputStream(is); bis.mark(Integer.MAX_VALUE); final StringBuilder stringBuilder = new StringBuilder(); try { // stream reader that handle encoding final InputStreamReader readerForEncoding = new InputStreamReader(bis, "UTF-8"); final BufferedReader bufferedReaderForEncoding = new BufferedReader(readerForEncoding); String encoding = extractEncodingFromStream(bufferedReaderForEncoding); if (encoding == null) { encoding = DEFAULT_ENCODING; } // stream reader that handle encoding bis.reset(); final InputStreamReader readerForContent = new InputStreamReader(bis, encoding); final BufferedReader bufferedReaderForContent = new BufferedReader(readerForContent); String line = bufferedReaderForContent.readLine(); while (line != null) { stringBuilder.append(line); line = bufferedReaderForContent.readLine(); } bufferedReaderForContent.close(); bufferedReaderForEncoding.close(); } catch (IOException e) { // reset string builder stringBuilder.delete(0, stringBuilder.length()); } result = stringBuilder.toString(); }else { result = null; } return result; } Regards, Quentin

  • BeautifulSoup HTMLParseError. What's wrong with this?

    - by user1915496
    This is my code: from bs4 import BeautifulSoup as BS import urllib2 url = "http://services.runescape.com/m=news/recruit-a-friend-for-free-membership-and-xp" res = urllib2.urlopen(url) soup = BS(res.read()) other_content = soup.find_all('div',{'class':'Content'})[0] print other_content Yet an error comes up: /Library/Python/2.7/site-packages/bs4/builder/_htmlparser.py:149: RuntimeWarning: Python's built-in HTMLParser cannot parse the given document.

  • Read specific line from text file, according to Checked Listbox selection number.

    - by Manolis
    Heya, i want to create an application which will read a specific line from a text file and show it in a textbox. The line will be chosen according to the number of the listbox selection i will make. Here's the code: Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim i As Integer For i = 0 To Me.CheckedListBox1.CheckedIndices.Count - 1 Me.CheckedListBox1.SetItemChecked(Me.CheckedListBox1.CheckedIndices(0),False) Next i End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click If CheckedListBox1.CheckedItems.Count <> 0 Then Dim reader As New System.IO.StreamReader(CurDir() & "\" & "READ.txt") Dim x As Integer Dim s As String = "" For x = 0 To CheckedListBox1.CheckedItems.Count - 1 s = s & "Answer " & (x + 1).ToString & ") " & CheckedListBox1.CheckedItems(x).ToString & ControlChars.CrLf & reader.ReadLine() & ControlChars.CrLf & ControlChars.CrLf Next x Answer.Text = (s) Else MessageBox.Show("Please select questions.", "Error", _ MessageBoxButtons.OK, _ MessageBoxIcon.Information) Return End If End Sub End Class So lets say i 'check' the first, second, and fifth items from the checked listbox, i want it to read from the text file the first, second, and fifth lines of text and show them in the textbox. The current code just reads line 1, 2, 3 (...) in order, no matter what item i have 'checked'. Thanks in advance!
