echo dir1 dir2 dir3 | xargs -n 1 cp file1

failed to load java vm library in OpenProj

We have set java jre. But still it was showing the message:

failed to load java vm library in OpenProj

Later we found that we have install jre for 64bit on a windows7. So, OpenProj couldn't find the java jre path. We have found that OpenProj runs on 32bit machine. So, we need to install java jre for 32 bit machine.
To edit the path, we need to go to the below path to edit OpenProj configuration file.

go to this path: C:\Users\tahsin.hasan\AppData\Roaming\OpenProj\{13702021-43FB-480C-912F-D9B74A538288}
Set the java jre to 32bit(x86) path.

how to update svn in mac?

We will follow the below steps to upgrade our svn version on mac machine.

In Terminal, type "svn --version" to find out what version you currently have.
Install macports and using macports install svn. this will install the latest svn into your system.
Got to your terminal and check your $PATH by typing "echo $PATH". If you don't see /opt/subversion/bin in there, make sure you add it by typing export PATH=/opt/subversion/bin:$PATH. If it DOES exist and appears AFTER /usr/bin, then you may need to remove an older copy of svn that came installed on OS X. To do so, go to /usr/bin and remove all files starting with svn. This isn't an exact science but it should do the trick.
Make sure you reload your .profile first by typing . ./.profile* or you can close the terminal and reopen again. also you can type source .profile. this will also reload profile.
Type "svn --version". You should see that you have the newest version installed!

Integrate Xcode with Corona SDK

1. Launch XCode, Create a new project, “File” > “New Project”
2. Template for project should be “Other” > “External Build System” and give the project a name and save it.
3. Under “Targets” in the left hand “Groups & Files” window in the main xcode editing window, then double click “Your Projects Name”
4. Remove all the “Build Settings”, dont know what they did but removing them didnt hurt
5. In “Build Tool” enter the path to either the “simulator” link or the “Corona Terminal” app just so you know, if you put the Corona folder in your Applications folder the the paths are as follows “/Applications/CoronaSDK/Corona Terminal” .
6. Under “Arguments” enter “$(PROJECT_DIR)”, this passes the location of the folder, what Corona looks for, to the simulator so it launches and builds the app without asking for the location of the project folder
7. Right click on the top of the main xcode window, the toolbar, and select “Customize Toolbar” and add the “Build” icon to the bar and click “Done”
8. Clicking the “Build” icon will now launch your application in Corona
9. If the corona simulator is already on and you save changes to the main.lua file, the simulator will prompt you to reload the lua file.
10. The project directory must contain a file that goes by the name of ‘main.lua’, this file can link itself to other modules.
11. Place Lua.pbfilespec and Lua.xclangspec in: ~/Library/Application Support/Developer/Shared/Xcode/Specifications/ and/or /Developer/Library/Xcode/Specifications/ http://f3gamesig.pbworks.com/w/file/42079531/Lua.pbfilespec http://f3gamesig.pbworks.com/w/file/42079528/Lua.xclangspec
12. reboot Xcode.

NOTE: If the directories don’t exist create them.

session.gc_maxlifetime value

This value (default 1440 seconds) defines how long an unused PHP session will be kept alive. For example: A user logs in, browses through your application or web site, for hours, for days. No problem. As long as the time between his clicks never exceed 1440 seconds. It's a timeout value. PHP's session garbage collector runs with a probability defined by session.gc_probability divided by session.gc_divisor. By default this is 1/100, which means that above timeout value is checked with a probability of 1 in 100. session.cookie_lifetime This value (default 0, which means until the browser's next restart) defines how long (in seconds) a session cookie will live. Sounds similar to session.gc_maxlifetime, but it's a completely different approach. This value indirectly defines the "absolute" maximum lifetime of a session, whether the user is active or not. If this value is set to 60, every session ends after an hour a minute.

How to Check What's Using Port 80 or 443

I am using Xampp. And Apache runs on port 80. When I install Skype or some other HTTP services, then it also runs on the same port. Hence, Apache can't run on this machine. So, I need to check which port is running on that port. To check this, need to do the followings:

1) Go to START-->Run and type cmd to bring up a Command prompt.
2) In the Command Prompt window. type netstat -aon.
3) Open up the Windows Task Manager
4) Then stop the process ID that was running on port 80.

size and daily/weekly/monthly not work together in logrotator

I have configured the logrotate file. And I have noticed that for some reason, my logrotate is not working. When I googled, I found that if you set the size value and the period together, they won't work.
The size and daily option don't work together in logrotate. So, I removed the period option and left the size option only, then it worked like a charm.

size 10K
