• RMI-applets - Cannot understand error message

  - by aeter

  In a simple RMI game I'm writing (an assignment in uni), I reveice: java.rmi.MarshalException: error marshalling arguments; nested exception is: java.net.SocketException: Broken pipe at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:138) at java.rmi.server.RemoteObjectInvocationHandler.invokeRemoteMethod(RemoteObjectInvocationHandler.java:178) at java.rmi.server.RemoteObjectInvocationHandler.invoke(RemoteObjectInvocationHandler.java:132) at $Proxy2.drawWorld(Unknown Source) at PlayerServerImpl$1.actionPerformed(PlayerServerImpl.java:180) at javax.swing.Timer.fireActionPerformed(Timer.java:271) at javax.swing.Timer$DoPostEvent.run(Timer.java:201) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:597) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122) The error message appears after the second Player is registered with the RMI Server and the server starts to send the image (the array of pixels) to the 2 applets. The PlayerImpl and the PlayerServerImpl both extend UnicastRemoteObject. I have been struggling with other error messages for some time now, but I cannot understand how to troubleshoot this one. Please help. The relevant parts of the code are: PlayerServerImpl.java: ... timer = new Timer(10, new ActionListener() { // every 10 milliseconds do: @Override public void actionPerformed(ActionEvent e) { ...

• How can I drag from a connected vertical list to the first item of a another list below with jQueryUI Sortable?

  - by Denis Hoctor

  Hi all, I have have several ULs vertically down a page. They are setup using jQueryUI's sortable(). My live example is: http://jsfiddle.net/pborreli/pJgyu/ I can drag from answers to make it the final element in questions. But when I drag from questions to answers the placeholder jumps to the second item in the questions list. At that point I can then drag it to the top. Any ideas why I am having this issue dragging from a list above to the first element of a list below? I've tried editing the padding and margin on both the lists and the sortable items. Thanks, Denis

• Oracle SQLPlus: How to display the output of a sqlplus command without having to first issue the spo

  - by ziggy

  Is there a way to display the output of a sqlplus command without having to first issue the spool off command? I am spooling the results of a sqlplus session to a file while at the same time tailing the file. The reason for this is that for table with very long rows the format is easier to look at from a file. The problem is to see the output i have to issue the spool off command everytime i run a command in sqlplus. Can i configure sqlplus so that after i have issued the spool command all the output is viewable straight away on the file. (Formating the way the rows are displayed on the screen is not an option. ) THanks

• Is it more efficient to always run a delete query, or to check if that information exists first

  - by Scarface

  Ok this is going to seem like a dumb question to experienced developers, but questions like this bother me until I ask them. So... is it more efficient to always run a delete query by default whether an entry exists or not, for example to delete a user name after a certain period of time (DELETE * from table where username=user), or should you check if that entry exists first using a select query and mysql_num_rows. What uses more processor on the server side? Obviously one approach contains more code, but I was wondering if certain mysql operations used a lot more cpu than others.

• Do .NET Timers Run Asynchronously?

  - by MrEdmundo

  I have a messaging aspect of my application using Jabber-net (an XMPP library.) What I would like to do, if for some reason the connection to the Server is ended, is keep trying to connect every minute or so. If I start a Timer to wait for a period of time before the next attempt, does that timer run asynchronously and the resulting Tick event join the main thread, or would I need to start my own thread and start the timer from within there?

• How do I keep existing values from shifting to the right when entering keypresses into a jQuery Mask

  - by Andrew

  I have a text box I'm using as a timer display "hh:mm:ss" When I select the box and press a number, it inserts the number at the cursor location, but instead of replacing the value at that position, it shifts all existing values over. For example, the timer text box reads "01:00:35" and I replace the first minute position with 1, the timer text box will then read "01:10:03." Anybody know how to force the text box to replace, instead of insert, at the cursor position? I've tried intercepting onKeyPress, doing the replace manually, rewriting the entire timer text, and then returning false. But, that doesn't worked with a jQuery masked input, because my function runs first.

• How to select the first row for each group in MySQL?

  - by Jader Dias

  In C# it would be like this: table .GroupBy(row => row.SomeColumn) .Select(group => group .OrderBy(row => row.AnotherColumn) .First() ) Linq-To-Sql translates it to the following T-SQL code: SELECT [t3].[AnotherColumn], [t3].[SomeColumn] FROM ( SELECT [t0].[SomeColumn] FROM [Table] AS [t0] GROUP BY [t0].[SomeColumn] ) AS [t1] OUTER APPLY ( SELECT TOP (1) [t2].[AnotherColumn], [t2].[SomeColumn] FROM [Table] AS [t2] WHERE (([t1].[SomeColumn] IS NULL) AND ([t2].[SomeColumn] IS NULL)) OR (([t1].[SomeColumn] IS NOT NULL) AND ([t2].[SomeColumn] IS NOT NULL) AND ([t1].[SomeColumn] = [t2].[SomeColumn])) ORDER BY [t2].[AnotherColumn] ) AS [t3] ORDER BY [t3].[AnotherColumn] But it is uncompatible with MySQL.

• Game of life in F# with accelerator

  - by jpalmer

  I'm trying to write life in F# using accelerator v2, but for some odd reason my output isn't square despite all my arrays being square - It appears that everything but a rectangular area in the top left of the matrix is being set to false.

• What frameworks to use to bootstrap my first production scala project ?

  - by Jacques René Mesrine

  I am making my first foray into scala for a production app. The app is currently packaged as a war file. My plan is to create a jar file of the scala compiled artifacts and add that into the lib folder for the war file. My enhancement is a mysql-backed app exposed via Jersey & will be integrated with a 3rd party site via HttpClient invocations. I know how to do this via plain java. But when doing it in scala, there are several decision points that I am pussyfooting on. scala 2.7.7 or 2.8 RC ? JDBC via querulous Is this API ready for production ? sbt vs maven. I am comfortable with maven. Is there a scala idiomatic wrapper for HttpClient (or should I use it just like in java) ? I'd love to hear your comments and experiences on starting out with scala. Thanks

• counter and displaylist AS3

  - by VideoDnd

  How can I connect my counter to my display list?I've got a counter and a displaylist working, but I need help with everything in between. Try to explain I finished a Snowflake tutorial. The snowballs are children that are called to the stage. When connected to a dynamic variable, they move around and look like snow. I want my counter to move numbers around.

• I have lots of images on a html page - how can i make certain ones load first (or certain ones load

  - by imlostmike

  Hi, i have a page with the main content area being big thumbnails, but elsewhere on the page are about 100-200 other (smaller) thumbs that are not important but must still show. What ways do i have to make the main ones show first (or the unimportant ones show last)? I was thinking of these ways: JS load: on page load (once it has finished loading), use a jquery's append() (or whatever other way) to write the html with the image code Set all unimportant images inside a div with style="display:none;". Then once the page has loaded, use JS to set it as visible what do you think is the best way?

• Real world example of Unification in First Order Logic?

  - by Sebi

  I know this is only part of a programming question, but at the moment, I'm doing a little bit of logic programming. One thing I still don't understand correctly is Unification in First Order Logic. I read the Wikipedia article and it is more or less clear that the purpose is searching a term that unifies two sentences... There are also examples in this article but I just don't get the point why this should be useful. Can anyone give an example with real world objects instead of A, B, C,, etc.? I hope this will help me to understand. Thanks

• How to use jasper reports to print something only on the first page ?

  - by Harsha

  How to use jasper reports to print something only on the first page. I am using jasper reports for printing invoices and only on the 1st page I need to print the Remit Payment To section with the address following it. Customer address is also present there. The way it is currently designed is that this goes into pageFooter section and we use printWhenExpression(PAGE_NUMBER = 1) so that this only gets printed on the 1st page of the invoice. But the downside of this approach is that the jasper engine reserves the size equivalent of the page footer on all the other pages (1..n) of the invoice. So we are able to use only about 2/3 rd of all pages. Remaining 1/3rd page which is for page footer is blank for all pages except the 1st page. This increases the number of pages. Any ideas for fixing this issue?

• Flip clock showing time issue (animations invovled)

  - by Hwang

  I'm creating a flip clock (clock where you always see in airport), but I can't seems to get the time to show at the correct timing. After the flip, then will see the number changing. But I want it to change before it flips. Currently I'm not sure whether is the animation problem, or isit I have to do something else on the script. I've uploaded the FLA so that you could have a look on how I set up the flipping animation. http://www.mediafire.com/?nzmymjgtntz Below is the AS3 code: package { import flash.display.MovieClip; import flash.events.TimerEvent; import flash.utils.Timer; public class flipClock extends MovieClip { private var clock:clockMC=new clockMC(); //seconds private var secTop1=clock.second.top1.digit; private var secTop2=clock.second.top2.digit; private var secBot1=clock.second.bot1.digit; private var secBot2=clock.second.bot2.digit; private var seconds:Number; private var minutes:Number; private var hours:Number; private var days:Number; public function flipClock():void { decrease(); addChild(clock); } private function decrease():void { var countdownTimer:Timer=new Timer(1000); //Adding an event listener to the timer object countdownTimer.addEventListener(TimerEvent.TIMER,updateTime); //Initializing timer object countdownTimer.start(); } private function updateTime(event:TimerEvent):void { decreasTimerFunction(); updateSecond(); //updateMinute(); } private function updateSecond():void { clock.second.play(); secTop1.text=num2; secTop2.text=num1; if (num1<10) { num1="0"+num1; } if (num2<10) { num2="0"+num2; } if (num1==60) { num1=0; } if (num2==60) { num2=0; } secTop1.text=num1; secTop2.text=num2; //secBot1.text=num1; //secBot2.text=num2; } private function decreasTimerFunction():void { //Create a date object for Christmas Morning var endTime:Date=new Date(2010,4,26,0,0,0,0); //Current date object var now:Date=new Date(); // Set the difference between the two date and times in milliseconds var timeDiff:Number=endTime.getTime()-now.getTime(); seconds=Math.floor(timeDiff/1000); minutes=Math.floor(seconds/60); hours=Math.floor(minutes/60); days=Math.floor(hours/24); // Set the remainder of the division vars above hours%=24; minutes%=60; seconds%=60; } } }

• Issue in parsing the GridViewRows in a Telerik RadGridView

  - by cricketmovies

  Hi, I would like to do something similar what we do in ASP.NET where we parse through all the rows in a GridView and assign a particular value to a particular cell in a row which has a matching TaskId as the current Id. This has to happen in a Tick function of a Dispatcher Timer object. Since I have a Start Timer button Column for every row in a GridView. Upon a particular row's Start Timer Button click, I have to start its timer and display in a cell in that row. Similarly there can be multiple timers running in parallel. For this I need to be able to check the task Id of the particular task and keep updating the cell values with the updated time in all of the tasks that have a Timer Started. TimeSpan TimeRemaining = somevalue; string CurrentTaskId = "100"; foreach(GridViewRow row in RadGridView1.Rows) // Here I tried RadGridView1.ChildrenOfType() as well but it has null { if( (row.DataContext as Task).TaskId == CurrentTaskId ) row.Cells[2].Content = a.TaskTimeRemaining.ToString(); } Can someone please let me know how do I get this functionality using the Telerik RadGridView? Cheers, Syed.

• ack (perl?) regexp matching lines where if is the first word

  - by Gauthier

  Hey. I'm finally learning regexps, training with ack. I believe this uses perl regexp. I want to match all lines where the first non-blank characters are if (<word> !, with any number of spaces in between the elements. This is what I came up with: ^[ \t]*if *\(\w+ *! It only nearly worked. ^[ \t]* is wrong, since it matches one or none [space or tab]. What I want is to match anything that may contain only space or tab (or nothing). For example these should not match: // if (asdf != 0) else if (asdf != 1) How can I modify my regexp for that?

• Why does the release build of my iPhone app crash on the device on the first run after installation?

  - by Chris Cooper

  I have an iPhone app that's been in development for about 2 weeks. We recently tried the "release" version of the build on a device, and to our great unhappiness, it crashes in one of the views with an "EXC_BAD_ACCESS". This crash only occurs on devices, and only in the "release" build. Not only that, but it only happens the first time the app is launched! It is also 100% reproducible. We have removed the small block of code that deals with data persistence, and have tried re-openning Xcode, cleaning the project, deleting and reinstalling the app, etc., as some other questions suggest. Do you have any advice for a) what might be causing this problem, and b) how to go about debugging if it only happens in "release"? Thanks

• Is the first persistance of an Entity Data Model in EF 4.0 slower due to the connection cost ?

  - by Scott Davies

  Hi, I've got a console app written that persists an object graph via Entity Framework 4.0. I loop through this to dump the execution times for each persistance. The first persistance is always the largest. Is this due to EF making the initial connection to the database and/or JIT'ing ? Here's a sample of the output: Persisted graph in **3318** millseconds. Persisted graph in 25 millseconds. Persisted graph in 26 millseconds. Persisted graph in 22 millseconds. Thanks, Scott

• Is it faster to do the pages first and CSS second, or should I do them at the same time?

  - by Fred Haslam

  I have been tasked with building a new web project from scratch, with the exception of reusing CSS files (the look and feel) from an existing project. In the past I have always completed development of the functionality and the web-ui before considering the appearance. This is mostly due to CSS development overlapping with the tail end of the project. I now have the opportunity to integrate a static set of CSS as I build the application. I have no experience with this circumstance. Would it be faster to develop the project and web-pages first, then integrate the CSS; or would it be faster to integrate the CSS as part of page development?

• GROUP BY as a way to pick the first row from a group of similar rows, is this correct, is there any

  I have a table which stores test results like this: user | score | time -----+-------+------ aaa | 90% | 10:30 bbb | 50% | 9:15 *** aaa | 85% | 10:15 aaa | 90% | 11:00 *** ... What I need is to get the top 10 users: user | score | time -----+-------+------ aaa | 90% | 11:00 bbb | 50% | 9:15 ... I've come up with the following SELECT: SELECT * FROM (SELECT user, score, time FROM tests_score ORDER BY user, score DESC, time DESC) t1 GROUP BY user ORDER BY score DESC, time LIMIT 10 It works fine but I'm not quite sure if my use of ORDER BY is the right way to pick the first row of each group of sorted records. Is there any better practice to achieve the same result? (I use MySQL 5)

• Do all header("Location: member.php?id=$username") have to be the first thing in a script? (PHP)

  - by ggfan

  I know in the Manuel it says that the header has to be the first thing in a script, but how come I see some codes where header("Location: member.php?id=$username") is in a if-statement? Ex: //a bunch of codes above if($result!="0"){ // authenication correct lets login $_SESSION["password"] = $password;; $_SESSION["username"] = $username; header("Location: member.php?id=$username"); } else { echo "Wrong username or password. Please try again!"; } But when I do this, it sometimes would/won't throw an error. How do I allow the header (); to be used in a script without any errors? I want to redirect the user back to the login if they click "no" and to the homepage if they click "yes".
