When in Eclipse you have an error like: “Access restriction: The constructor AppletAudioClip(URL) is not accessible due to restriction on required library C:\Programmi\Java\jdk1.6.0_24\jre\lib\rt.jar” You simply need to follow these steps to avoid compilation error:

Click on the Properties of your project Go to Java Compiler–>Errors/Warnings search for “Deprecated and Restricted API” and set to warning “Forbidden reference (access rules)” item.

That’s it.

To open a port by using iptables you can use the iptables command, assume for example that you want to open port 25, you have to issue on the shell the following command

iptables -I INPUT -p tcp –dport 25 -j ACCEPT

where -I instruct to not add the rulle after the deny all rule avoiding to not be checked by iptables. At the end you have to save your changes with

service iptables save

and restart the service with

service iptables restart

However you can also edit directly the configuration file that in CentOS is in /etc/sysconfig/iptables

When you run a remote shell (for example putty) and you start a remote cli program (e.g. tomcat, servicedesk, jboss and so on) when you close the remote shell normally they would terminate. To avoid this situation you can try to run the program in background (adding & at the end of the command or using the combination CTRL-Z and after the command bg)  but there are some cases in which the child process will continue to receive signal from the parent process (e.g. SIGINT), so you can overcome this by using the nohup command (which will cause the program to ignore signals sent from the shell).

Example think that you have a run.sh script to run,  to avoid to be interrupted when you close the remote shell just write this:

nohup run.sh &

Mounting is an easy process to do, provided the filesystem type you are using is supported. What happen when you have an LVM formatted disk, and you need to mount it because the disk cannot be booted and a hell lot of valuable data kept inside?? Do not worry, because the solution is here…….

1. Get a live cd, for example, Ubuntu. For this article, I use Ubuntu 6.06 (I cannot find any latest version of ubuntu at my place)

2. Boot using the live cd. Search for these tools: lvm2. If the cd do not have it, install it.
# apt-get install lvm2

3. To make sure the harddisk is recognised, you can use fdisk
# fdisk -lu

4. Once installed, run pvscan to scan all disks for physical volume. this to make sure your LVM harddisk is detected by Ubuntu
# pvscan
PV /dev/sda2 VG VolGroup00 lvm2 [74.41 GB / 32.00 MB free]
Total: 1 [74.41 GB] / in use: 1 [74.41 GB] / in no VG: 0 [0 ]

5. After that run vgscan to scan disks for volume groups.
# vgscan
Reading all physical volumes. This may take a while…
Found volume group “VolGroup00″ using metadata type lvm2

6. Activate all volume groups available.
# vgchange -a y
2 logical volume(s) in volume group “VolGroup00″ now active

7. Run lvscan to scan all disks for logical volume. You can see partitions inside the hard disk now active.
# lvscan
ACTIVE ‘/dev/VolGroup00/LogVol00′ [72.44 GB] inherit
ACTIVE ‘/dev/VolGroup00/LogVol01′ [1.94 GB] inherit

8. Mount the partition to any directory you want, usually to /mnt
# mount /dev/VolGroup00/LogVol00 /mnt

9. You can access the partition in the /mnt directory and can backup your data

To enable keywords substitution as I usually have with the CVS, you just need to enable a svn properties on the Eclipse project configuration.

These are the steps to activate the svn-keyword-substitution feature in Eclipse:

1. Install Subclipse into your Eclipse application
2. Right-mouse-click on your project folder, and choose Team => Set Property from the popup menu (note to click on the root of the project folder)
3. Enter the property name:  svn:keywords
4. Enter the text property:  Author Date Id Revision HeadURL
   
5. Click the  Set property recursively checkbox
6. OK

Note that on large project files this action could take also several minutes. Now keywords are substituted when you commit a file in SVN, just like they were by using CVS.  Also, you can shorten Revision to Rev and HeadURL to URL.

So if you now have a file like:

// File name: $HeadURL$
// Revision: $Revison$
// Last modified: $Date$
// Last modified by: $Author$
//
//  file description

commiting it to the SVN will result into:

//  File name: afile.php
//  Revision: 1
//  Last modified: 2010-11-4 14:53
//  Last modified by: quonn
//
//  file description

You can generate an SSH key on Windows using the PuTTY SSH client. You can download PuTTY for free from this URL.

To generate a key with PuTTY, you should:

1. Download and start the puttygen.exe generator.

2. In the “Parameters” section choose SSH2 DSA (if your server uses RSA you have to choose SSH2 RSA) and press Generate.

3. Move your mouse randomly in the small screen in order to generate the key pairs.

4. Enter a key comment, which will identify the key (useful when you use several SSH keys).

5. Type in the passphrase and confirm it. The passphrase is used to protect your key. You will be asked for it when you connect via SSH.

6. Click “Save private key” to save your private key.

7. Click “Save public key” to save your public key.

For more information on how to load the key and connect via SSH using PuTTY, please check this article.

I am hearing about this social application by some day, and even if I haven’t really understand the utility of this social app, I will give you an abstract of what it is and link the symbian download page for Nokia mobile phone owners.

Foursquare is a mobile application that is a cross between a friend-finder, a social city-guide, and a game that rewards you for doing interesting things. Foursquare lets you “check in” to a place when you’re there, tell friends where you are, and track the history of where you’ve been–and who you’ve been there with. Foursquare challenges you to explore your city in new and fun ways by earning points, winning mayorships, and unlocking badges and specials for trying new places and revisiting old favorites

The Nokia apps could be downloaded here. Enjoy it
