  • Rails CSS not Loading using Heroku

    - by eWizardII
    I have the following site set up here on Heroku - http://www.peerinstruction.net/users/sign_up the issue is that I have updated the css yet it is not being actively reflected on the site, it just shows a textbox, with some edited/custom fonts. I have attached the css file in the following gist - https://gist.github.com/f74b626c54ecbb60bbde The signup page controller: !!!

  • Fork in Perl not working inside a while loop reading from file

    - by Sag
    Hi, I'm running a while loop reading each line in a file, and then fork processes with the data of the line to a child. After N lines I want to wait for the child processes to end and continue with the next N lines, etc. It looks something like this: while ($w=<INP>) { # ignore file header if ($w=~m/^\D/) { next;} # get data from line chomp $w; @ws = split(/\s/,$w); $m = int($ws[0]); $d = int($ws[1]); $h = int($ws[2]); # only for some days in the year if (($m==3)and($d==15) or ($m==4)and($d==21) or ($m==7)and($d==18)) { die "could not fork" unless defined (my $pid = fork); unless ($pid) { some instructions here using $m, $d, $h ... } push @qpid,$pid; # when all processors are busy, wait for child processes if ($#qpid==($procs-1)) { for my $pid (@qpid) { waitpid $pid, 0; } reset 'q'; } } } close INP; This is not working. After the first round of processes I get some PID equal to 0, the @qpid array gets mixed up, and the file starts to get read at (apparently) random places, jumping back and forth. The end result is that most lines in the file get read two or three times. Any ideas? Thanks a lot in advance, S.

  • Bored with CS. What can I study that will make an impact?

    - by Eric Martinez
    So I'm going to an average university, majoring in CS. I haven't learned a damn thing and am in my third year. I've come to be really bored with studying CS. Initially, I was kind of misinformed and thought majoring in CS would make me a good "product creator". I make my money combining programming and business/marketing. But I have always done programming for the love of the art. I find things like algorithms interesting and want to be able to use CS to solve real world problems. I like the idea of bioinformatics and other hybrid studies. I'm not good enough, yet I hope, to really make a significant effort in those areas but I aspire to be. What are some other fields, open problems, and otherwise cool stuff to apply CS knowledge to in the real world? I'm really looking for something that will motivate me and re-excite me to continue studying CS. Edit: Like someone mentioned below. I am very interesting in the idea of being able to use computer science to help answer fundamental questions of life and the universe. But I'm not sure what is possible or how to begin.

  • Is there any other efficient way to use table variable instead of using temporary table

  • how to push a string address to stack with assembly, machine code

    - by Yigit
    Hi all, I am changing minesweeper.exe in order to have an understanding of how code injection works. Simply, I want the minesweeper to show a message box before starting. So, I find a "cave" in the executable and then define the string to show in messagebox and call the messagebox. Additionally of course, I have to change the value at module entry point of the executable and first direct it to my additional code, then continue its own code. So at the cave what I do; "hello starbuck",0 push 0 //arg4 of MessageBoxW function push the address of my string //arg3, must be title push the address of my string //arg2, must be the message push 0 //arg1 call MessageBoxW ... Now since the memory addresses of codes in the executable change everytime it is loaded in the memory, for calling the MessageBoxW function, I give the offset of the address where MessageBoxW is defined in Import Address Table. For instance, if MessageBoxW is defined at address1 in the IAT and the instruction just after call MessageBoxW is at address2 instead of writing call MessageBoxW, I write call address2 - address1. So my question is, how do I do it for pushing the string's address to the stack? For example, if I do these changes via ollydbg, I give the immediate address of "hello starbuck" for pushing and it works. But after reloading the executable or starting it outside of ollydbg, it naturally fails, since the immediate addresses change. Thanks in advance, Yigit.

  • How to detect if an application has UI elements in it from C# in Windows 7?

    - by Santhosh
    I have a c# application in Windows 7 that runs in Session 0. This application is basically a framework for software patches installation that will install patches in the background (in session 0). So this app will download patches from the server and start installing them on the client machines. The way it installs the patches is by calling CreateProcess("Patch.exe"). Now mostly, Patch.exe will be a non-ui silent installation and henceforth, installing the patch from session 0 goes through successfully. However, sometimes this Patch.exe happens to have some UI elements in it such as prompting the user for some details (like installation location, etc..) and let us say that these UI elements cannot be avoided. So is it possible for my installation framework (that runs in Session 0 written in C#), to know that the process Patch.exe which was created by my framework has any UI elements in it? The reason I ask is, if I determine that the application has any UI elements in it, then I do not want to continue with the installation (a crude way of doing this would be to kill the installer process Patch.exe, but that is a different story and not of concern here).

  • handling java exception

    - by Noona
    This questions is related to java exception, why are there some cases that when an exception thrown the program exits even though the exception was caught and there was no exit() statement? my code looks something like this void bindProxySocket(DefaultHttpClientConnection proxyConnection, String hostName, HttpParams params) { if (!proxyConnection.isOpen()) { Socket socket = null; try { socket = new Socket(hostName, 80); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } try { proxyConnection.bind(socket, params); } catch(IOException e) { System.err.println ("couldn't bind socket"); e.printStackTrace(); } } } and then I call this method like this: bindProxySocket(proxyConn, hostName, params1); but, the program exits, although I want to handle the exception by doing something else, can it be because I didn't enclose the method call within a try catch clause? what happens if I catch the exception again even though it's already in the method? and what should I do if i want to clean resources only if an exception occurs and otherwise I want to continue with the program? I am guessing in this case I have to include the whole piece of code until I can clean the resources with in a try statement or can I do it in the handle exception statement? some of these questions are on this specific case, but I would like to get a thorough answer to all my questions for future reference. thanks

  • Problem consuming Exchange Web Service 2010 with jax-ws metro

    - by Johan Karlberg
    I am trying to consume the Exchange 2010 Web Service interface using JAX-WS. I'm using JAX-WS 2.2 RI (Metro 2.0). 2.1 exhibited the same problem. I am running into trouble with Exchange, which returns "HTTP/1.1 415 Cannot process the message because the content type 'text/xml;charset=utf-8' was not the expected type 'text/xml; charset=utf-8'." as a reponse (2.1 quoted the charset value, otherwise same response). Apparently I need to dictate the exact Content-type header for Exchange to be happy. Is there a way for me to do this without forcing me to manually rebuild the dependency? I currently rely on published maven artifacts, and would like to continue doing this if at all possible. The consuming process is a regular J2SE app, with no containers in sight. I have control of the application and can add pretty much anything required to the applications scope, but can not add out-of-process items like proxy servers. The client classes were generated from local WSDL, but the charset specification is derived from constants declared in the jaxws RI implementation, not the generated code. The resulting HTTP transport is thus handled by the standard http/https client from Sun JRE5 or JRE6.

  • Word Macros Problem: MsgBox function appears to lock all open windows of word

    - by amby
    I have some Macros that run in Word. We are migrating to Office 2007. Problem: the MsgBox function appears to lock all open windows of word. Any Ideas on how to get around that? (It is a macro that walks a user through a bunch of prompts for information that they enter into user forms and or MsgBoxes.) The error says: The command cannot be completed because a dialog box is open. Click OK then close all open dialog boxes to continue. Is there any way to have each window of word act independently of each other? The problem is that the information is frequently cut and pasted from other open word documents, and this doesn't work as the MsgBox locks control of ALL windows of Word 2007. The macros are pretty simple, but if you want to see the code, I will certainly post it. Basically, the old version of office let you go between windows, while 2007, that we are migrating to does not. I have run all the updates I could find. Any help would be greatly appreciated.

  • Mostly PJAX site with some AngularJS

    - by jrhicks
    I have a site using PJAX all over the place and I have a few pages that are using AngularJS. For the AngularJS pages I would like to continue to use PJAX to get all the benefits associated with not reloading the entire HTML page, assets etc. Unfortunately, PJAX just loads some HTML into the page and doesn't fire any javascript. This is okay, because I can fire the javascript manually on pjax success, but I can't quite figure out what makes AngularJS initialize. For a simple scenario, lets say I AJAX the following HTML into a page. Also assume, the page already had Angular.js included. What could I call to have the following behave like an Angular App? <div> <label>Name:</label> <input type="text" ng-model="yourName" placeholder="Enter a name here"> <hr> <h1>Hello {{yourName}}!</h1> </div> Thanks

  • Java process is not terminating after starting an external process

    - by tangens
    On Windows I've started a program "async.cmd" with a ProcessBuilder like this: ProcessBuilder processBuilder = new ProcessBuilder( "async.cmd" ); processBuilder.redirectErrorStream( true ); processBuilder.start(); Then I read the output of the process in a separate thread like this: byte[] buffer = new byte[ 8192 ]; while( !interrupted() ) { int available = m_inputStream.available(); if( available == 0 ) { Thread.sleep( 100 ); continue; } int len = Math.min( buffer.length, available ); len = m_inputStream.read( buffer, 0, len ); if( len == -1 ) { throw new CX_InternalError(); } String outString = new String( buffer, 0, len ); m_output.append( outString ); } Now it happened that the content of the file "async.cmd" was this: REM start a command window start cmd /k The process that started this extenal program terminated (process.waitFor() returned the exit value). Then I sent an readerThread.interrupt() to the reader thread and the thread terminated, too. But there was still a thread running that wasn't terminating. This thread kept my java application running even if it exited its main method. With the debugger (eclipse) I wasn't able to suspend this thread. After I quit the opened command window, my java program exited, too. Question How can I quit my java program while the command window stays open?

  • iPhone dev - viewDidUnload subviews

    - by Mk12
    I'm having a hard time undestand a couple of the methods in UIViewController, but first I'll say what I think they are meant for (ignoring interface builder because I'm not using it): -init: initialize non view-related stuff that won't need to be released in low memory situations (i.e. not objects or objects that can't be recreated easily). -loadView: create the view set the [self view] property. -viewDidLoad: Create all the other view elements -viewDidUnload: Release objects created in -viewDidLoad. didReceiveMemoryWarning: Low-memory situation, release unnecessary things such as cached data, if this view doesn't have a superview then the [super didReceiveMemoryWarning] will go on to release (unload) the view and call -viewDidUnload. -dealloc: release everything -viewWillAppear:, -viewDidAppear:, -viewWillDisappear:, -viewDidDisappear: self-explanatory, not necessary unless you want to respond (do something) to those events. I'm not sure about a couple of things. First, the Apple docs say that when -viewDidUnload is called, the view has already been released and set to nil. Will -loadView get called again to recreate the view later on? There's a few things I created in -viewDidLoad that I didn't make a ivar/property for because there is no need and it will be retained by the view (because they are subviews of it). So when the view is released, it will release those too, right? When the view is released, will it release all its subviews? Because all the objects I created in -viewDidLoad are subviews of [self view]. So if they already get released why release them again in -viewDidUnload? I can understand data that is necessary when the view is visible being loaded and unloaded in these methods, but like I asked, why release the subviews if they already get released? EDIT: After reading other questions, I think I might have got it (my 2nd question). In the situation where I just use a local variable, alloc it, make it a subview and release, it will have a retain count of 1 (from adding it as a subview), so when the view is released it is too. Now for the view elements with ivars pointing to them, I wasn't using properties because no outside class would need to access them. But now I think that that's wrong, because in this situation: // MyViewController.h @interface MyViewController : UIViewController { UILabel *myLabel; } // MyViewController.m . . . - (void)viewDidLoad { myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 40, 10)]; [myLabel setText:@"Foobar"]; [[self view] addSubview:myLabel]; } - (void)viewDidUnload [ // equivalent of [self setMyLabel:nil]; without properties [myLabel release]; myLabel = nil; } In that situation, the label will be sent the -release message after it was deallocated because the ivar didn't retain it (because it wasn't a property). But with a property the retain count would be two: the view retaining it and the property. So then in -viewDidUnload it will get deallocated. So its best to just always use properties for these things, am I right? Or not? EDIT: I read somewhere that -viewDidLoad and -viewDidUnload are only for use with Interface Builder, that if you are doing everything programmatically you shouldn't use them. Is that right? Why?

  • How can I programmatically add more than just one view object to my view controller?

    - by BeachRunnerJoe
    I'm diving into iPhone OS development and I'm trying to understand how I can add multiple view objects to the "Left/Root" view of my SplitView iPad app. I've figured out how to programmatically add a TableView to that view based on the example code I found in Apple's online documentation... RootViewController.h @interface RootViewController : UITableViewController <NSFetchedResultsControllerDelegate, UITableViewDelegate, UITableViewDataSource> { DetailViewController *detailViewController; UITableView *tableView; NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; } RootViewController.m - (void)loadView { UITableView *newTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; newTableView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth; newTableView.delegate = self; newTableView.dataSource = self; [newTableView reloadData]; self.view = newTableView; [newTableView release]; } but there are a few things I don't understand about it and I was hoping you veterans could help clear up some confusion. In the statement self.view = newTableView, I assume I'm setting the entire view to a single UITableView. If that's the case, then how can I add additional view objects to that view alongside the table view? For example, if I wanted to have a DatePicker view object and the TableView object instead of just the TableView object, then how would I programmatically add that? Referencing the code above, how can I resize the table view to make room for the DatePicker view object that I'd like to add? Thanks so much in advance for your help! I'm going to continue researching these questions right now.

  • PHP execute command as subcommand

    - by Thomaschaaf
    I have the following 2 files and am executing them on linux (debian). File1.php <?php exec("php -f file2.php > /dev/null 2>&1 &"); sleep(100); File2.php <?php exec("sleep 30 > /dev/null 2>&1 &"); exec("sleep 30 > /dev/null 2>&1 &"); sleep(100); The way it currently is it first starts file1.php and fires up file2.php and immediatly begins the sleep commands. It does not wait for the first sleep to finish to continue. The problem is that the file2.php and sleep commands are not subcommands of file1.php and I can't simply kill it to kill all subcommands. My htop looks like this: http://dl.getdropbox.com/u/5910/Jing/2011-01-13_1611.png I am searching for a way to have the commands be subcommands of file1.php so that I can easily kill them all :) what I have: '- php -f file2.php '-sleep 30 '-sleep 30 '- php -f file1.php basically I want this: '- php -f file1.php '- php -f file2.php '-sleep 30 '-sleep 30

  • Best terminal environment for Cygwin/Windows?

    - by Anders Sandvig
    Today I run Cygwin with rxvt using the following startup line: rxvt -bg black -sl 8192 -fg white -sr -g 150x56 -fn "Fixedsys" -e /usr/bin/bash --login -i This gives me a resizeable native Windows window which is much better than the standard "DOS box" the default cygwin.bat provides. However, the current configuration does have a couple of issues: I am not able to enter non-ASCII characters into the terminal window (i.e. æ, ø, å and Æ, Ø, Å, which I use semi-frequently. In fact, the terminal will not even accept them when I paste them into the window. If I paste a string like "bølle" (Norwegian for "bulley"), all I get is "blle". I am not able to render UTF-8 character, they only show as ?, even if they are supported by the font (i.e. when rendering the same characters in ISO-8859-1 they show just fine.). I am running English Windows Vista with locale and keyboard layout set to Norwegian (ISO-8859-1 character set?), but I've had the exact same issue on Windows 2000 and XP. Anyone knows how to fix this (i.e. a better way to configure rxvt)? Apart from the issues mentioned above, I'm very happy with rxvt, so if I find a way to resolve them I'd like to continue using it. However, if the issues are not (easily) solvable, are the any other good terminal solutions for Cygwin? Update The solution provided by Andy and Mattias (editing the .inputrc file) did solve the input problem, but output rendering is still an issue. Output is fine when I render in ISO-8859-1, but when using UTF-8 I only get ? for non-ASCII characters. This behavior is consistent between rxvt, urxvt (under Cygwin XFree X Server), mintty and PuttyCyg. Is there a similar configuration file where output encoding can be set (i.e. the equivalent of setting output locale on a Linux system)?

  • delete UITableView row apple addMusic example

    - by Pavan
    Hi, i am trying to add a swipe to delete feature to the addmusic example project (downloaded free from apple) so that i am able able to delete a specific row. Ive added the following code just so that i can enable to delete feature but i dont know how to remove the song from the list which i believe to be the mediaItemCollection and actually deleting it from the userMediaItemCollection which is used to queue the songs to the player. - (void)tableView:(UITableView*)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath { } - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { // If row is deleted, remove it from the list. if (editingStyle == UITableViewCellEditingStyleDelete) { // delete your data item here // Animate the deletion from the table. [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]withRowAnimation:UITableViewRowAnimationFade]; } } The swipe to delete feature works nicely, the delete button only appears when swiped, but when i click delete, a SIGBART error occurs, the whole application freezes, (although the musix does continue to play, lol). Can someone please tell me how i can delete the row at that index and how i can delete it from the mediaitemcollection please. When taking that single line of code out: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]withRowAnimation:UITableViewRowAnimationFade]; the swipe to delete works, except that it does not delete anything obviously since i havent added any actual delete functionality/coding that needs to be done. All ideas appreciated.

  • mySQL Efficiency Issue - How to find the right balance of normalization...?

    - by Foo
    I'm fairly new to working with relational databases, but have read a few books and know the basics of good design. I'm facing a design decision, and I'm not sure how to continue. Here's a very over simplified version of what I'm building: People can rate photos 1-5, and I need to display the average votes on the picture while keeping track of the individual votes. For example, 12 people voted 1, 7 people voted 2, etc. etc. The normalization freak of me initially designed the table structure like this: Table pictures id* | picture | userID | Table ratings id* | pictureID | userID | rating With all the foreign key constraints and everything set as they shoudl be. Every time someone rates a picture, I just insert a new record into ratings and be done with it. To find the average rating of a picture, I'd just run something like this: SELECT AVG(rating) FROM ratings WHERE pictureID = '5' GROUP by pictureID Having it setup this way lets me run my fancy statistics to. I can easily find who rated a certain picture a 3, and what not. Now I'm thinking if there's a crapload of ratings (which is very possible in what I'm really designing), finding the average will became very expensive and painful. Using a non-normalized version would seem to be more efficient. e.g.: Table picture id | picture | userID | ratingOne | ratingTwo | ratingThree | ratingFour | ratingFive To calculate the average, I'd just have to select a single row. It seems so much more efficient, but so much more uglier. Can someone point me in the right direction of what to do? My initial research shows that I have to "find the right balance", but how do I go about finding that balance? Any articles or additional reading information would be appreciated as well. Thanks.

  • How should I implement lazy session creation in PHP?

    - by Adam Franco
    By default, PHP's session handling mechanisms set a session cookie header and store a session even if there is no data in the session. If no data is set in the session then I don't want a Set-Cookie header sent to the client in the response and I don't want an empty session record stored on the server. If data is added to $_SESSION, then the normal behavior should continue. My goal is to implement lazy session creation behavior of the sort that Drupal 7 and Pressflow where no session is stored (or session cookie header sent) unless data is added to the $_SESSION array during application execution. The point of this behavior is to allow reverse proxies such as Varnish to cache and serve anonymous traffic while letting authenticated requests pass through to Apache/PHP. Varnish (or another proxy-server) is configured to pass through any requests without cookies, assuming correctly that if a cookie exists then the request is for a particular client. I have ported the session handling code from Pressflow that uses session_set_save_handler() and overrides the implementation of session_write() to check for data in the $_SESSION array before saving and will write this up as library and add an answer here if this is the best/only route to take. My Question: While I can implement a fully custom session_set_save_handler() system, is there an easier way to get this lazy session creation behavior in a relatively generic way that would be transparent to most applications?

    Hello friends, I am trying to implement 'scrollview' effect in 'Tabbar' which has 'TabItems'. I found that the good example is from 'facebook' open source 'TTCatlog' project 'Tabs' section. So i included all the source from it to my project and trying to build it. I have followed the following links to go ahead on this: http://stackoverflow.com/questions/822792/how-to-create-a-horizontal-scrolling-view-on-iphone source: http://github.com/facebook/three20/tree/master/samples/ My calling code is like below: _tabBar1 = [[TTTabStrip alloc] initWithFrame:CGRectMake(10, 68, 300, 28)]; _tabBar1.tabItems = [NSArray arrayWithObjects: [[[TTTabItem alloc] initWithTitle:@"Item 1"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 2"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 3"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 4"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 5"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 6"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 7"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 8"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 9"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 10"] autorelease], nil]; [self.navigationController.view addSubview:_tabBar1]; My project folder as like below: ..../iphone/MyProgram/MyProgram.xcodeproj ..../iphone/Three20/src/Three20.... In my project settings for header search path, I have ../Three20/src But when i try to build it, it throws the following error: "objc_class_name_TTTabStrip symbol not found" "objc_class_name_TTTabItem symbol not found" I see there, all these files (.h and .m) are availbale there. Could someone please help what's wrong there and how do i get rid of this issue and continue working with it?

  • Is it possible to unstick a remote IIS ASP server after an exception hangs the session?

    - by user89691
    I have been coding an app in classic ASP that accesses 2 Access databases. I had a page I was working on throw an exception, which is normal during development and causes no lasting problems. This time however, after the exception any attempt to open either of the databases would freeze the session with an infinite script timeout. If I delete the session cookie I an able to access ASP pages again until I try to open the database again. The database that was open when the exception was thrown is left open. There is a LDB lock file and I can't rename or delete either the LDB or MDB file, though I can download the MDB file with FTP. The 2nd access database is not open but any attempt to read this also hangs the session. Accessing HTML pages is fine. The site is hosted with Hostway and they are not interested ("Coding problem = Your problem" even though it leaves my site dead in the water, I suspect until the next reboot, whenever that might be). Here is the dump from the relevant ASP page that threw the exception: Active Server Pages error 'ASP 0115' Unexpected error /translatestats.asp A trappable error (C0000005) occurred in an external object. The script cannot continue running. Active Server Pages error 'ASP 0240' Script Engine Exception /translatestats.asp A ScriptEngine threw exception 'C0000005' in 'IActiveScript::Close()' from 'CActiveScriptEngine::FinalRelease()'. Is there any way I can unstick the site / force close the database remotely ?
