• Posting New html from TINYMCE

  - by matthewb

  Seems like a simple problem, I have a form and when someone needs to edit data, the textarea that is controlled by TINYMCE loads the values, but when I change it and submit the form, the new changes are not being posted. What am I doing wrong? UPDATE How do I do it via this, or do it say on click in the editor. I am using jquery validate, this is the submit handler. $(form).ajaxSubmit({ target:'#result', success:function(){ $('html, body').animate({scrollTop:'90px'}, 500);}, clearForm: false}); }});

• VisualStudio: Toggle Archive Attribute When Saving File?

  - by John Dibling

  We use Tortoise CVS in out shop, but in my last job we used Visual SourceSafe. VSS is generally a pile, but it did have one nice feature. You could right-click on a branch and ask it for a list of all the files you had checked-out. As far as I can tell there is no similar feature in CVS. So what I'm looking for is some kind of VS plusgin that will automatically reset (turn off) the archive attribute when saving a file. Then I can recursively dir to find the files I have checked-out. Does anyone know of a VS plugin or something I can do to get this behavior? Or is there something else I can do in CVS to get my ultimately desired result?

• Make the Enter key act like the submit button

  - by Michael Quiles

  How can I make it where some one presses the enter key on my form it will submit this code ? Ive tried the ligtning bolt events etc... but I can't seem to figure it out. private void xTripSubmitButton_Click(object sender, EventArgs e) { // Calculates the numbers from the input and output boxes/labels Miles = double.Parse(this.xTripDestinationTextBox.Text); Mpg = double.Parse(this.xTripMpgTextBox.Text); Price = double.Parse(this.xTripPricepgTextBox.Text); Output = Miles / Mpg; Coutput = Output * Price; //displays a message and the result for the numbers the user inputs this.xTripOutputLabel.Text = "Total gallons you would use: " + Output.ToString("0") + Environment.NewLine + "Total amount it will cost you: " + Coutput.ToString("C"); }

• How to combine two arrays of same length to one array with two fields (not append/merge)

  - by Raj

  Say, I have an array with months $months = array('Jan', 'Feb', 'Mar'...'Dec'); And another, with days (say, for year 2010) $mdays = array(31, 28, 31...31); I want to merge/combine these two arrays, into an array like this: $monthdetails[0] = ('month' => 'Jan', 'days' => 31) $monthdetails[1] = ('month' => 'Feb', 'days' => 28) ... $monthdetails[11] = ('month' => 'Dec', 'days' => 31) I can loop through both the arrays and fill the $monthdetails. I want to know whether there are any functions/easier way for achieving the same result. Thanks! Raj

• Search in big text log files

  - by 0xFF

  Hi, let's say you have an game server which creating text log files of gamers actions, and from time to time you need to lookup something in those logs files (like investigating an scam or loosing an item). Just for example you have 100 files and each file have size between 20MB and 50MB - How you would search them quickly? What I have already tried to do is create several threads and each invidual thread will map his own file to memory (let say memory should not be problem if it not exceed 500MB of ram) perform search here, result was something around 1 second per file : File:a26.log - read in: 0.891, lines: 625282, matches: 78848 Is there better way how to do that ? - because it seems to me kinda slow. thanks. (java was used for this case)

• difference between 2 pieces Python code

  - by draw

  Hello, I'm doing an exercise as following: # B. front_x # Given a list of strings, return a list with the strings # in sorted order, except group all the strings that begin with 'x' first. # e.g. ['mix', 'xyz', 'apple', 'xanadu', 'aardvark'] yields # ['xanadu', 'xyz', 'aardvark', 'apple', 'mix'] # Hint: this can be done by making 2 lists and sorting each of them # before combining them. sample solution: def front_x(words): listX = [] listO = [] for w in words: if w.startswith('x'): listX.append(w) else: listO.append(w) listX.sort() listO.sort() return listX + listO my solution: def front_x(words): listX = [] for w in words: if w.startswith('x'): listX.append(w) words.remove(w) listX.sort() words.sort() return listX + words as I tested my solution, the result is a little weird. Here is the source code with my solution: http://dl.dropbox.com/u/559353/list1.py. You might want to try it out.

• How to generate all permutations of a string in PHP ?

  - by Johan

  I need an algorithm that return all possible combination of all characters in one string. I've tried: $langd = strlen($input); for($i = 0;$i < $langd; $i++){ $tempStrang = NULL; $tempStrang .= substr($input, $i, 1); for($j = $i+1, $k=0; $k < $langd; $k++, $j++){ if($j > $langd) $j = 0; $tempStrang .= substr($input, $j, 1); } $myarray[] = $tempStrang; } But that only returns the same amount combination as the length of the string. Say the $input is = "hey", the result would be: hey, hye, eyh, ehy, yhe, yeh.

• LINQ - if condition

  - by ile

  In code, the commented part is what I need to solve... Is there a way to write such query in LINQ? I need this because I will need sorting based on Status. var result = ( from contact in db.Contacts join user in db.Users on contact.CreatedByUserID equals user.UserID join deal in db.Deals on contact.ContactID equals deal.ContactID into deals orderby contact.ContactID descending select new ContactListView { ContactID = contact.ContactID, FirstName = contact.FirstName, LastName = contact.LastName, Email = contact.Email, Deals = deals.Count(), EstValue = deals.Sum(e => e.EstValue), SalesAgent = user.FirstName + " " + user.LastName, Tasks = 7, // This is critical part if(Deals == 0) Status = "Prospect"; else Status = "Client"; // End of critical part... }) .OrderBy(filterQuery.OrderBy + " " + filterQuery.OrderType) .Where(filterQuery.Status);

• C++: is it safe to read an integer variable that's being concurrently modified without locking?

  - by Hongli

  Suppose that I have an integer variable in a class, and this variable may be concurrently modified by other threads. Writes are protected by a mutex. Do I need to protect reads too? I've heard that there are some hardware architectures on which, if one thread modifies a variable, and another thread reads it, then the read result will be garbage; in this case I do need to protect reads. I've never seen such architectures though. This question assumes that a single transaction only consists of updating a single integer variable so I'm not worried about the states of any other variables that might also be involved in a transaction.

• Qt: QAbstractItemModel and 'const'

  - by Eye of Hell

  Hello. I'm trying to use a QTreeView for a first time, with a QAbstractItemModel. And instantly it's a problem: QAbstractItemModel interface declares methods as 'const', assuming they will not change data. But i want a result of SQL query displayed, and returning data for a record with specified indeq REQUIRES to use QSqlQuery::seek() that is a non-const. Is it any 'official' guideline to use a QAbstractItemModel with data that MUST be changed in order to get number of items, data per item etc? Or i must hack C++ with const casts?

• C#: How to unit test a method that relies on another method within the same class?

  - by michael paul

  I have a class similar to the following: public class MyProxy : ClientBase<IService>, IService { public MyProxy(String endpointConfiguration) : base(endpointConfiguration) { } public int DoSomething(int x) { int result = DoSomethingToX(x); //This passes unit testing int result2 = ((IService)this).DoWork(x) //do I have to extract this part into a separate method just //to test it even though it's only a couple of lines? //Do something on result2 int result3 = result2 ... return result3; } int IService.DoWork(int x) { return base.Channel.DoWork(x); } } The problem lies in the fact that when testing I don't know how to mock the result2 item without extracting the part that gets result3 using result2 into a separate method. And, because it is unit testing I don't want to go that deep as to test what result2 comes back as... I'd rather mock the data somehow... like, be able to call the function and replace just that one call.

• Experiences teaching or learning map/reduce/etc before recursion?

  - by Jay

  As far as I can see, the usual (and best in my opinion) order for teaching iterting constructs in functional programming with Scheme is to first teach recursion and maybe later get into things like map, reduce and all SRFI-1 procedures. This is probably, I guess, because with recursion the student has everything that's necessary for iterating (and even re-write all of SRFI-1 if he/she wants to do so). Now I was wondering if the opposite approach has ever been tried: use several procedures from SRFI-1 and only when they are not enough (for example, to approximate a function) use recursion. My guess is that the result would not be good, but I'd like to know about any past experiences with this approach.

• Handling file upload in a non-blocking manner

  - by Kaliyug Antagonist

  The background thread is here Just to make objective clear - the user will upload a large file and must be redirected immediately to another page for proceeding different operations. But the file being large, will take time to be read from the controller's InputStream. So I unwillingly decided to fork a new Thread to handle this I/O. The code is as follows : The controller servlet /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse * response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub System.out.println("In Controller.doPost(...)"); TempModel tempModel = new TempModel(); tempModel.uploadSegYFile(request, response); System.out.println("Forwarding to Accepted.jsp"); /*try { Thread.sleep(1000 * 60); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); }*/ request.getRequestDispatcher("/jsp/Accepted.jsp").forward(request, response); } The model class package com.model; import java.io.IOException; import java.util.concurrent.ExecutionException; import java.util.concurrent.Future; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.utils.ProcessUtils; public class TempModel { public void uploadSegYFile(HttpServletRequest request, HttpServletResponse response) { // TODO Auto-generated method stub System.out.println("In TempModel.uploadSegYFile(...)"); /* * Trigger the upload/processing code in a thread, return immediately * and notify when the thread completes */ try { FileUploaderRunnable fileUploadRunnable = new FileUploaderRunnable( request.getInputStream()); /* * Future<FileUploaderRunnable> future = ProcessUtils.submitTask( * fileUploadRunnable, fileUploadRunnable); * * FileUploaderRunnable processed = future.get(); * * System.out.println("Is file uploaded : " + * processed.isFileUploaded()); */ Thread uploadThread = new Thread(fileUploadRunnable); uploadThread.start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } /* * catch (InterruptedException e) { // TODO Auto-generated catch block * e.printStackTrace(); } catch (ExecutionException e) { // TODO * Auto-generated catch block e.printStackTrace(); } */ System.out.println("Returning from TempModel.uploadSegYFile(...)"); } } The Runnable package com.model; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.nio.ByteBuffer; import java.nio.channels.Channels; import java.nio.channels.ReadableByteChannel; public class FileUploaderRunnable implements Runnable { private boolean isFileUploaded = false; private InputStream inputStream = null; public FileUploaderRunnable(InputStream inputStream) { // TODO Auto-generated constructor stub this.inputStream = inputStream; } public void run() { // TODO Auto-generated method stub /* Read from InputStream. If success, set isFileUploaded = true */ System.out.println("Starting upload in a thread"); File outputFile = new File("D:/06c01_output.seg");/* * This will be changed * later */ FileOutputStream fos; ReadableByteChannel readable = Channels.newChannel(inputStream); ByteBuffer buffer = ByteBuffer.allocate(1000000); try { fos = new FileOutputStream(outputFile); while (readable.read(buffer) != -1) { fos.write(buffer.array()); buffer.clear(); } fos.flush(); fos.close(); readable.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("File upload thread completed"); } public boolean isFileUploaded() { return isFileUploaded; } } My queries/doubts : Spawning threads manually from the Servlet makes sense to me logically but scares me coding wise - the container isn't aware of these threads after all(I think so!) The current code is giving an Exception which is quite obvious - the stream is inaccessible as the doPost(...) method returns before the run() method completes : In Controller.doPost(...) In TempModel.uploadSegYFile(...) Returning from TempModel.uploadSegYFile(...) Forwarding to Accepted.jsp Starting upload in a thread Exception in thread "Thread-4" java.lang.NullPointerException at org.apache.coyote.http11.InternalInputBuffer.fill(InternalInputBuffer.java:512) at org.apache.coyote.http11.InternalInputBuffer.fill(InternalInputBuffer.java:497) at org.apache.coyote.http11.InternalInputBuffer$InputStreamInputBuffer.doRead(InternalInputBuffer.java:559) at org.apache.coyote.http11.AbstractInputBuffer.doRead(AbstractInputBuffer.java:324) at org.apache.coyote.Request.doRead(Request.java:422) at org.apache.catalina.connector.InputBuffer.realReadBytes(InputBuffer.java:287) at org.apache.tomcat.util.buf.ByteChunk.substract(ByteChunk.java:407) at org.apache.catalina.connector.InputBuffer.read(InputBuffer.java:310) at org.apache.catalina.connector.CoyoteInputStream.read(CoyoteInputStream.java:202) at java.nio.channels.Channels$ReadableByteChannelImpl.read(Unknown Source) at com.model.FileUploaderRunnable.run(FileUploaderRunnable.java:39) at java.lang.Thread.run(Unknown Source) Keeping in mind the point 1., does the use of Executor framework help me in anyway ? package com.utils; import java.util.concurrent.Future; import java.util.concurrent.ScheduledThreadPoolExecutor; public final class ProcessUtils { /* Ensure that no more than 2 uploads,processing req. are allowed */ private static final ScheduledThreadPoolExecutor threadPoolExec = new ScheduledThreadPoolExecutor( 2); public static <T> Future<T> submitTask(Runnable task, T result) { return threadPoolExec.submit(task, result); } } So how should I ensure that the user doesn't block and the stream remains accessible so that the (uploaded)file can be read from it?

• Get count matches in query on large table very slow

  - by Roy Roes

  I have a mysql table "items" with 2 integer fields: seid and tiid The table has about 35000000 records, so it's very large. seid tiid ----------- 1 1 2 2 2 3 2 4 3 4 4 1 4 2 The table has a primary key on both fields, an index on seid and an index on tiid. Someone types in 1 or more tiid values and now I would like to get the seid with most results. For example when someone types 1,2,3, I would like to get seid 2 and 4 as result. They both have 2 matches on the tiid values. My query so far: SELECT COUNT(*) as c, seid FROM items WHERE tiid IN (1,2,3) GROUP BY seid HAVING c = (SELECT COUNT(*) as c, seid FROM items WHERE tiid IN (1,2,3) GROUP BY seid ORDER BY c DESC LIMIT 1) But this query is extremly slow, because of the large table. Does anyone know how to construct a better query for this purpose?

• Reading Matrices in MATLAB and assigning coordinates to the entries

  - by Michael Schofield

  Hi, I'm a bit new to MATLAB. Basically, I have a 25x25 Matrix, complete with various random entries ranging from 0 to 3. I need to write a program that reads this matrix, and assigns x-y coordinates to the entries, so that when I ask for an input of a particular x-y coordinate which has, say an entry of 3, then it will result in an error. I'm a bit overwhelmed - but I understand the general concept of what I'm supposed to be finding. I'm wondering if I should use a plot instead to help me.

• Return no records if FIndKey results in False?

  - by jwilfong

  Using TDataSet.FindKey you can locate records. When it results in True the datasets cursor will be positioned on the found record. When it results in False the cursor is not moved. This results in the record data prior to FindKey being issued being displayed in data aware components. How can I code the result of FindKey to return an empty record? if Not tblSomeTable.FindKey([SomeSearchData]) then begin < code to return empty or move data cursor to neutral position > end; Thanks, John

• Process AJAX response with long runing tasks

  - by mpz

  I have long time task in controller action. I use delayed job for it. (Also in heroku it is good practice for perfomance - dyno must work for small time in each request) But my client need result of it work and users can wait on that task. It is more clear: no any addition models or records in it, simple view and js... I think about such way: On client run AJAX with very long timeout (5 min for example) Client make request to server as usual On controller in action1 def start_work (with delay work setup) i need NO any response to client After work performs (delay job finished) i need run new action2 with response to client Client recieve response after about 1-5 min It is possible?

• Sed substitution not doing what I want and think it should do

  - by nategoose

  I have am trying to use sed to get some info that is encoded within the path of a file which is passed as a parameter to my script (Bourne sh, if it matters). From this example path, I'd like the result to be 8 PATH=/foo/bar/baz/1-1.8/sing/song I first got the regex close by using sed as grep: echo $PATH | sed -n -e "/^.*\/1-1\.\([0-9][0-9]*\).*/p" This properly recognized the string, so I edited it to make a substitution out of it: echo $PATH | sed -n -e "s/^.*\/1-1\.\([0-9][0-9]*\).*/\1/" But this doesn't produce any output. I know I'm just not seeing something simple, but would really appreciate any ideas about what I'm doing wrong or about other ways to debug sed regular expressions.

• Can review changes in Acrobat Reader (Pro, or not) be 'applied' to a PDF?

  - by Danjah

  Hi there, As part of an enhancement to my workplace processes, we're trying to streamline review of various documents. Yeah, there's way better alternatives to what I'm about to suggest, but the reality is that I have no time allocated to investigate things like DAV, repo setups and such. What I do have time allocated for is improving workflow around tools we already use. So I tried to work through the Adobe PDF collaborative review cycle. I have to say it was pretty amazing, from the notify toolbar icon to doc merging, to user access control. They offer it all, EXCEPT the ability to actually apply review changes to a PDF!?! To clarify, after sending a PDF through the collab review cycle (involving a bunch for external editors and internal staff) the end result was a PDF full of rich feedback - but I can see no way to finalised and apply those 'accepted' review points to the PDF in question. I hope this is clear enough, feel free to ask questions to clarify - perhaps I'm just missing something obvious, but perhaps applying changes to an already existing PDF is not possible? -d

• DB2 increase bufferpool size and compressed tables not equal better performance. Why?

  - by Mestika

  Hi, I’m working on tuning and increasing the performance of my IBM DB2 version 9.7 database. I’ve been searching around the net for the last couple of days and learned that if I created my tables in COMPRESS mode and created one more bufferpool and set both of them to access 1024mb, then the performance in my queries should increase because of the less I/Os to the disks. However, when I run my time analysis, the performance Decrease. I added the new additions to my regular database with the indexes I’ve used all the time. Each time I search google I come up with the statement that: Increased bufferpool size and several bufferpools AND a table compression SHOULD prove to get better performance. I’m very puzzled about the total unexpected result. Are there some tuning mechanisms I’ve forgot or does anyone have a explanation for this odd behavior? Sincerely Mestika
