  • Error appearing in application after updating cakePHP library files from 1.3.0 to 1.3.1

    - by Gaurav Sharma
    Hi everyone, I have just updated my cakephp library to latest version 1.3.1. Before this I was running v1.3.0 with no errors. After running the application I am given this error message. unserialize() [function.unserialize]: Error at offset 0 of 2574 bytes [CORE\cake\libs\cache\file.php, line 176] I updated the libraries simply by replacing the existing cake files with the new ones downloaded from the net. Is it the correct way of updating applications. I did'nt made any customizations to the core library of cakePHP. What is the problem ? Please help. Thanks

  • How to build a Video Broadcaster, which can handle more than 20,000 viewers

    - by Gaurav Srivastava
    I want to broadcast Video from a web cam, over internet. The problem is, the Video will be viewed live by more than 20,000 people (expected). I have a very little experience with Red5 Broadcasting. I did some broadcasting using Red5 and Flash. It works fine for 1 or 2 viewers i.e. it is great for personal chatting/ video conferencing applications. But, when the number of viewers increases, the delay in Broadcasting also increases. I am experiencing a Delay addition of about 0.5 Seconds for every new user who joins the broadcast. Can any one suggest me some, better technologies on which I can work out this Live Broadcasting. I don't want to use http://www.ustream.com; I want to create one of my own, such tool. But thats always the last solution.

  • Dynamically/recursively building hashes in Perl?

    - by Gaurav Dadhania
    I'm quite new to Perl and I'm trying to build a hash recursively and getting nowhere. I tried searching for tutorials to dynamically build hashes, but all I could find were introductory articles about hashes. I would be grateful if you point me towards the right direction or suggest a nice article/tutorial. I'm trying to read from a file which has paths in the form of one/two/three four five/six/seven/eight and I want to build a hash like VAR = { one : { two : { three : "" } } four : "" five : { six : { seven : { eight : "" } } } } The script I'm using currently is : my $finalhash = {}; my @input = <>; sub constructHash { my ($hashrf, $line) = @_; @elements = split(/\//, $line); if(@elements > 1) { $hashrf->{shift @elements} = constructHash($hashrf->{$elements[0]}, @elements ); } else { $hashrf->{shift @elements} = ""; } return $hashrf; } foreach $lines (@input) { $finalhash = constructHash($finalhash, $lines); }

  • Right method to build a online whiteboard - JAVA

    - by Nikhar Sharma
    I am building a whiteboard, which would have a server(teacher) and clients(students). Teacher would draw something on his side, which will be shown exactly same to the students. I want to know which component i should use to do the drawing? i am currently drawing on JPanel . I want the screen of Server gets copied on the clients, so for that what could be the right method to do this? option1: i save the JPanel as image, and send thru socket, and loads it on the screen of client, also it always saves the background image only, not what the user has drawn onto it. OR option2: both server and client JPanel dimensions are same, so i just send the new coordinates drawn everytime thru socket, with some protocol to understand whether it is rubber or pencil.. Any help would be appreciated.

    - by Gaurav
    I am developing an application which runs on both honeycomb and ice cream sandwich. I want my action bar not to have the icon but keep the "up/home" button. I used: getActionBar().setDisplayOptions(0, ActionBar.DISPLAY_SHOW_HOME); This removes the action bar icon but keeps the "up" button on ice cream sandwich. But on honeycomb, it removes the "up" button as well. Is there a way on honeycomb that allows me to keep the "up" button but get rid of the icon?

  • Prevent unauthorised write access to a part of filesystem or partition

    - by gaurav
    Hello all I have some very important system files which I want to protect from accidental deletion even by root user. I can create a new partition for that and mount it with readonly access but the problem is that I want my application which handles those system files to have write access to that part and be able to modify them. Is that possible using VFS? As VFS handles access to the files I could have a module inserted in the VFS layer which can see if there is a write access to that part then see the authorization and allow it or otherwise reject it. If not please provide me suggestions regarding how can such a system be implemented what would I need in that case. If there exists a system like this please suggest about them also. I am using linux and want to implement this in C, I think it would be possible in C only. Edit: There are such kind of programs implemented in windows which can restrict access to administrator even, to some important folders, would that be possible in linux?
