If we are unable to maintain a good relationship with Facebook, our business will suffer.

Facebook is the primary distribution, marketing, promotion and payment platform for our games. We generate substantially all of our revenue and players through the Facebook platform and expect to continue to do so for the foreseeable future. Any deterioration in our relationship with Facebook would harm our business and adversely affect the value of our Class A common stock.

We are subject to Facebook’s standard terms and conditions for application developers, which govern the promotion, distribution and operation of games and other applications on the Facebook platform. We have entered into an addendum to these terms and conditions pursuant to which we have agreed to use Facebook Credits, Facebook’s proprietary payment method, as the primary means of payment within our games played through Facebook. This addendum expires in May 2015.

Our business would be harmed if:

• Facebook discontinues or limits access to its platform by us and other game developers;
• Facebook terminates or does not renew our addendum;
• Facebook modifies its terms of service or other policies, including fees charged to, or other restrictions on, us or other application developers, or Facebook changes how the personal information of its users is made available to application developers on the Facebook platform or shared by users;
• Facebook establishes more favorable relationships with one or more of our competitors; or
• Facebook develops its own competitive offerings.

We have benefited from Facebook’s strong brand recognition and large user base. If Facebook loses its market position or otherwise falls out of favor with Internet users, we would need to identify alternative channels for marketing, promoting and distributing our games, which would consume substantial resources and may not be effective. In addition, Facebook has broad discretion to change its terms of service and other policies with respect to us and other developers, and those changes may be unfavorable to us. For example, in 2010 Facebook adopted a policy requiring applications on Facebook accept only its virtual currency, Facebook Credits, as payment from users. As a result of this change, which we completed in April 2011, Facebook receives a greater share of payments made by our players than it did when other payment options were allowed. Facebook may also change its fee structure, add fees associated with access to and use of the Facebook platform, change how the personal information of its users is made available to application developers on the Facebook platform or restrict how Facebook users can share information with friends on their platform. Beginning in early 2010, Facebook changed its policies for application developers regarding use of its communication channels. These changes limited the level of communication among users about applications on the Facebook platform. As a result, the number of our players on Facebook declined. Any such changes in the future could significantly alter how players experience our games or interact within our games, which may harm our business.

Then you read that you can now reserve a Amazon Relational Database Service (RDS) instance so you look for the button on the Console and find that Amazon haven’t added this feature yet. So what do you do? Here is a step by step guide for novice user of the Command Line Interface (CLI) on how to reserve an instance.

Download public/private keys:

1. Login to http://aws.amazon.com

2. Point to “Your Account” and click “Security Credentials”

3. In the Access Credentials section of the page, click the X.509 Certificates tab.

4. Click Create a New Certificate.

Your X.509 certificate and corresponding private key are generated.

5. From the dialog box, download your private key file and X.509 certificate file.

Setup the RDS CLI:

1. Download the RDS Command Line Interface (CLI) RDSCli.zip

2. Unzip to C:\RDSCli

3. C:\set AWS_RDS_HOME=C:\RDSCli\RDSCli-1.3.003

4. C:\set EC2_CERT=c:\keys\cert-********************************************.pem

5. C:\set EC2_PRIVATE_KEY=c:\keys\pk-********************************************.pem

Reserve Instance:

1. First use the rds-describe-reserved-db-instances command to returns the list of DB Instance reservations for your account or details for one of your reserved database instances.

C:\rds-describe-reserved-db-instances –region eu-west-1

If you have no existing reserved RDS instances for the specified region then this will return nothing.

2. Next use rds-describe-reserved-db-instances-offerings to returns the list of DB Instance offerings that are available for purchase.

C:\rds-describe-reserved-db-instances-offerings –region eu-west-1

3. Looking at the list of instance types and prices select the ID of the one you require, in my case the db.m1.small for 1 year and use the rds-purchase-reserved-db-instances-offering command to purchase it.

C:\RDSCli\RDSCli-1.3.003\bin>rds-purchase-reserved-db-instances-offering ceb6a579-a4f3-4b55-ac53-7208e3c4b0fd –region eu-west-1 -c 1

4. Check a while later to see the status, it should now be active.

C:\RDSCli\RDSCli-1.3.003\bin>rds-describe-reserved-db-instances –region eu-west-1

RESERVATION  ri-2010-11-17-13-17-40-410  db.m1.small  n  2010-11-17T13:19:19.272Z  1y  1  active  mysql

All done, you have now purchased your RDS reserved instance.

1. Screen captures

Use the built-in screen capture shortcut (hold the “home” button, then hit the “power/sleep” button) to capture of your screen as a photo. You can then use these images to create an animation or include in a PowerPoint presentation.

Advantage: No extra software or equipment required.

Disadvantage: Not a true capture of the app use, just a series of screen shots.

2. Video Camera

Use a video camera to show someone using the app.

Advantages: It shows a true working scenario.

Disadvantages: Relatively easy to do but difficult to do well i.e. camera needs to be stable, the lighting needs to be correct to prevent glare on the screen and the users hands can get in the way of the screen.

3. Screen capture the simulator

If you have the Xcode IDE and the iPhone Simulator installed on a Mac then you can run the app in the simulator and capture the screen then use a tool like iShowU to do a video capture of the simulator on your Mac screen.

Advantages: Good representation of the working app.

Disadvantages: The simulator is not an exact copy of the iPhone device and not everything works the same especially if you are trying to show features like dialing a number or a hardware feature such as the camera which is not included in the simulator.

4. Capture the iPhone screen

The final option is to record the iPhone screen itself. This is something when you first go to do it you think there should be a straight forward way either via a built in feature or an app but there isn’t.

This can however be done as follows but only on a jailbroke phone:

1. Install ScreenSplitr via Cydia on the iPhone
2. On the Mac install iDemo
3. Install iShowU on the Mac (or a similar tool)
4. Start ScreenSplitr on the iPhone
5. Launch iDemo on the Mac (the iPhone may ask you to accept the connection) – it will list available phones (this will work via. USB or WiFi)
6. Launch iShowU to record the session.

I have only tried this on the iPhone 3 with ScreenSplitr but Display Recorder may be better  but only runs on 3GS and higher.

Advantages: Allows you to record a true life demo directly from the iPhone device.

Disadvantages: You need a jailbroke phone and there are allot of pieces to get working.

The new Skype Access service provides a very convenient way to access public WiFi hotspots in hotels, airports and other public locations. While there are many places that offer free WiFi and many of us use some sort of mobile broadband there are always times especially when traveling that you are confronted by a screen where you have to “sign up for…”, “enter code…”, “pay with credit card” etc.

For those interested in developing for the platform. There are tutorials an SDK and tools available from developer.bada.com. The developer tools are based on Eclipse and C++.

Samsung are also running a Developer Challenge competition with a prize fund of $2,700,000 consisting of 300 prizes up to $300,000.

There have been several releases of VirtualBox in the last year which have including enhanced support for VMware .vmdk virtual disk files. With support for .vmdk disks moving from VMware to VirtualBox on either Windows or OS X is as simple as:

• Mount the .vmdk disk using the “Virtual Media Manager”
• Create a new Virtual Machine with the approprtate settings using the disk

While VMware Workstation is an excellent product needing to buy a Windows version and a Mac version doubles the cost and using it on additional machines needs additional licenses.

VirtualBox is available in two editions:

• VirtualBox Open Source Edition (OSE) – This addition is available as source code you can build yourself under the GPL licence.

• VirtualBox – This edition adds RDP and USB support to the OSE version and is available as a easy to install binary distribution. This is released under a Personal Use and Evaluation License (PUEL). The license is explained here and includes:

“It doesn’t matter whether you just use it for fun or run your multi-million euro business with it. Also, if you install it on your work PC at some large company, this is still personal use. However, if you are an administrator and want to deploy it to the 500 desktops in your company, this would no longer qualify as personal use.”

Summary:

• VirtualBox is a good alternative to VMware workstation with similar functionality.
• Moving an existing virtual machine from VMware to VirtialBox is a simple process.
• The PUEL license covers most development and testing scenarios for multiple users in an organisation at no cost.

1. Turn down logging

Logging can be turned down by editing MobileConnect.exe.config and Settings.xml in C:\Program Files\Vodafone\Vodafone Mobile Connect\Bin\ as follows.

MobileConnect.exe.config

Settings.xml

2.  Don’t start the Mobile Connect software at logon

Use Autoruns to prevent Mobile Connect from starting at logon. It will start from the menu when you want to use the modem.
