To scan a new card to your iPhone/iPods contacts is simple:

1. From the main screen press the icon

2. A listing of tips to increase the accuracy is displayed. Press OK to continue or Don’t Show Again to not be notified of these tips in future

3. At this point you can simply line up the business card within the guidelines and press the button to capture the card. However, a great feature included in this app is the Anti-Shake Mode capture. Line up the card within the guidelines, press the button and the app will wait until the camera is steady enough to take an accurate snapshot of the card.

4. Once a snapshot of the card has been taken, simply click the Recognize button and the app will scan the acquired image for contact information

5. A new contact record will be displayed containing the acquired information from the card snapshot. Add to or edit this information as required then press the Export button to create a new contact in your iPhone/iPods contact list

There are a number of business card scanner apps in the App Store but personally I found the speed and accuracy of WorldCard Mobile exceeded that of the other apps that I compared.

Enter Alfresco!

Alfresco is an Open Source Content Management System (CMS) incorporating key principles of document management, record management, web content management and enterprise collaboration. I have had Alfresco on my “to look into” list for some time now so I thought I would bite the bullet and see if it could conquer our current file management woes. What I would like to achieve from this project includes the following:

• Collaborative content management of student and staff data
• Anywhere access to collaborative and personal data from any web capable device
• Document version control (revision history)
• Single sign-on (SSO) authentication tied to our network directory (Active Directory)
• Integration with other collaborative services such as Moodle and Google Apps
• Centralised management for ICT staff
• Multi platform support (Windows, OS X and various Linux distributions)

Building upon these fundamental points, I would like for staff and students to have a space where they can continue to collaborate together outside the schools walls. The system would allow us to provide their content to them via the local network (ie: mapped CIFS drive) internally or via various web protocols from outside the school on their chosen device – hence maintaing anywhere access. Throughout the schools ICT systems we implement a standard whereby if the system requires authentication the user is able to use their single network directory (active Directory) credentials thus upholding a Sigle sign-on (SSO) cluster of systems. This would need to continue throughout the various facilities within the Alfresco CMS.

The school has implemented Moodle as its Learning Management System (LMS) and has employed the services of a Google Apps Educational account to provide email and other collaborative services to every student and teacher. The Alfresco CMS would need to tie into these current systems and further them to the benefit of the students learning. Our Moodle LMS currently resides on a Linux server which would also need to be able to call upon content stored within Alfresco’s filesystem hierarchy. In tern, Alfresco would be required to be accessible by the multiplatform structure that we have in place throughout the school.

From my reading, which has merely scratched the surface of what Alfresco can provide, I am confident that this CMS will be able to fulfill the school’s requirements and continue to exceed them as we explore its facilities. In the near future I hope to build a test server using Alfresco’s freely available Community Edition to put the system through its paces and confirm that it will be able to fulfill our needs before proceeding down the path of a production server and storage solution. My aim is to document my  way through this project via this blog. This process may be slow whilst I find some free time if that does indeed still exist in this world we live in…

Handbrake is an open source video transcoder available for Windows, Mac and Linux and comes equipped with various conversion setting presets. Handbrake can convert a single video file, a queue of video files or a DVD video in a few simple steps:

1. Select the source video file or DVD title/folder
   
2. Select a destination for the converted file
   
3. Select a conversion preset or configure the specific audio/video settings
   
4. For a single file conversion click the Start button or click Add to Queue if you wish to convert multiple files. Click Start once you have added all videos to the queue
   
5. The conversion process will start and notify you once all videos in the queue are complete

Note: For greater compatibility with iTunes, enable the ‘Use iPod/iTunes friendly (.m4v) file extension for MP4′ setting

Handbrake is by far the best free MP4 video transcoder that I have come across. Let me know your opinions or alternatives that you may use in the comments.

Yahoo! have become the first service to offer free video calls from iOS devices to non-iOS devices such as a desktop computer or (soon) Android smartphone. The call process is similar to that of FaceTime or placing a Skype voice call and can be initiated or received on either device. The process of making a video call is as simple as selecting an online contact and pressing the video call (webcam) icon or accepting the call if the call has been initiated from another device.

Sending Video Call Request

Receiving Video Call Request

The video quality is nowhere near that of FaceTime, but the app does have the advantages of; working not just on Wifi but also on 3G, it is available on all iOS4 devices not just iPhone 4 and iPod Touch Gen 4 and is not limited by only allowing iOS to iOS video calls. This app has taken a huge step in minimising the current proprietary nature of iPhone video calling (ie: FaceTime only works for iOS device to iOS device).

One thing to note is that the app currently does not seem to be able to accept calls from the Mac OS X version of Yahoo! Messenger. We must remember that this is the first app to successfully provide this type of service and I am sure future updates will improve and strengthen the service. Well done Yahoo!

1. Change the file extension of the Pages file from .pages to .zip
   (You must first show file extensions in windows explorer)
   
   
2. Open the newly renamed zip file and browse to the QuickLook folder.
3. The QuickLook folder will contain a PDF file named Preview.pdf. This file is a PDF version of the original Apple iWork Pages document.

Done!

The prerequisites for MRBS are as follows:

- PHP 4/5
- MySQL or PostgreSQL
- A web server (such as Apache) that supports PHP
- PHP-LDAP Modules (optional for LDAP authentication)

Luckily enough I already had an Ubuntu Linux production server in place with these prerequisites installed so I was ready to go. The install process is as follows:

1. Extract the contents of the MRBS.tar.gz file to your web servers storage folder (ie: Apache – htdocs, IIS -inetpub)
2. Create a mrbs database in MySQL
   CREATE DATABASE `mrbs` ;
3. Create the database table structure using the supplied tables.my.sql script
   (Optional: Add sample data to the database using the supplied sample-data.sql script)
4. You must enter a timezone into the config.inc.php file before the system will function (ie: $timezone = “Sydney/Australia;)

At this point the system is ready to use. However, I recommend a few extra steps for ease of use in a school environment:

Enable period view and define school periods:

The default view for MRBS is time slots. Generally schools work to periods not time slots so a period view has been included in MRBS.
To enable the period view:

1. Include the following line of code in your config.inc.php file:
   $enable_periods = TRUE;
2. Define the periods in the config.inc.php file. Example:
3. $periods[] = “Before School”;
   $periods[] = “Mentor”;
   $periods[] = “Period 1″;
   $periods[] = “Period 2″;
   $periods[] = “Recess”;

   And so on…

Activate LDAP authentication:

We endeavor to provide a single-sign-on environment for our staff and students which means that LDAP authentication is a must have for any system that we implement into our network. This process was by far the hardest part of the MRBS install and took my colleague and I sometime to complete mainly due to the PHP-LDAP modules.
To enable LDAP authentication:

1. Install PHP-LDAP modules
   I am not going to go into installing these modules in this post but am happy to lend a hand if you need help getting these working.
2. Define LDAP authentication commands in the config.inc.php file. Example:
   $auth['only_admin_can_book_repeat'] = TRUE;$auth["type"] = “ldap”;

   $ldap_host = “yourdomain.com.au”;
   $ldap_port = 389;
   $ldap_v3 = true;
   $ldap_tls = false;
   $ldap_base_dn = “ou=Users,dc=yourdomain,dc=com,dc=au”;
   $ldap_user_attrib = “sAMAccountName”;
   $ldap_dn_search_dn = “cn=Admin,ou=Users,dc=yourdomain,dc=com,dc=au”;
   $ldap_dn_search_attrib = “sAMAccountName”;
   $ldap_dn_search_password = “Admin_Password”;

3. Define admin users from LDAP in the config.inc.php file
   $auth["admin"] = “Admin”;

Being open source the opportunities to endless for you to critique this system to your individual needs. We have edited various files within the system to do the following:

• Only allow admins to create repeat bookings
• Change field labels by editing the language file (lang.en)
• Apply the users username to the end of the displayed booking so staff can easily see who has made the booking
• Add an “Override Creator” field for admins only so that they can make a booking on a staff members behalf
• Edit the Help page to be more school specific help

The app includes the following features:

• Basic IPv4 Subnet Calculator
  
• VLSM Subnet Calculator
  
• SuperNet Finder
  
• CIDR / Dotted Mask Converter
  
• Binary / Hex / Decimal Converter
  

There are free subnet calculator apps out there but not with the range of features that The Mask is offering. I highly recommend this app!

I thought that I would start the new file association section with playing compressed RAR files that contain video files. I recently downloaded a video file from a source that had compressed and split the video file into a number of RAR part files. I wanted to make sure that the file was in fact the video that I was after without having to download all the RAR parts to be able to do so. I came across Dziobas RAR Player that allowed me to do just that and the following is how this is achieved:

1. Download and install Dziobas RAR Player
2. Open Dziobas RAR Player and from the File menu, select Streaming from unrar… (no rewind)
   
3. Select the RAR file containing the video file and click Open
   Note: You can select any number part file (ie: video.part3.rar) as long as you have the parts proceeding this file in the same folder. You must also make sure that you have part1 before you will be able to play any of the file.

4. The software will now ask you for the RAR files password. If the file is not password protected simply click OK. if the file is password protected, enter the password then press OK.
   
5. A command prompt window will now be displayed letting you know what the player is doing. Do not close this window as the process of attempting to decompress and play the video file will stop if you are to do so. If successful, the video should start playing in a new window.
   Note: If you are using Windows Vista and 7 your colour scheme will be changed to basic whilst the video is playing. Once the video has completed or is closed, your colour scheme settings will return to normal.
   

I have found that some video files allow you to fast forward using the mouse scroll wheel or keyboard arrow keys. From my limited use of the software, I have achieved this with RAR files containing MPG files but majority of AVI files do not allow for fast forwarding.

I am primarily a Windows user but support both OS X and Linux workstations and servers. This being the case, majority of my posts will be Windows related but from time to time I will attempt to throw in the odd OS X or Linux application.

Searching through the logs pointed me in the direction of the Exchange services and sure enough one of the services had not started automatically as it should have. The service in question was the Microsoft Exchange System Attendant. Starting this service resolved the issue straight away. I have since restarted the server and the service continues to not start automatically. One to watch…

• Start -> Administrative Tools -> Services
• Right-Click Microsoft Exchange System Attendant service
• Select Start from displayed context menu
