Software Genres• Trial software:
– Limited time usage (e.g. 30 days)– Need to buy after expiry of time limit
• Shareware:– Can continue free use but with some restrictions, e.g. watermark
on document• Open Source Software:
– Copyright still with author– Use license depends on license type– Source codes are given– Source code amendments depend on license agreement– More than 60 licenses under the Open Source Software license
• Software as a Service (SaaS):– software that is deployed over the internet and/or – is deployed to run behind a firewall in your local area network or
personal computer
新 跃 大 学
Trial Software
• Try the software before you buy!
• Many of products may be downloaded for free to take them for a spin. If you like what you see, you may purchase the software later without losing any of your work.
• Example: http://www.rootsmagic.com/Try/

Shareware - 1
• Memories-on-TV• http://download.cnet.com/MemoriesOnTV/3000-
12511_4-10134414.html• allows you to create professional slideshows easily from
your digital photos and video clips • video you create can be burnt onto CD/DVD recordable
using the built-in burner and then played on a TV via a standard DVD player
• You can also output your show to web pages (Flash), or save them as AVI or MPG files.
• You can have effects such as multi-pictures on single slide, slideshow in slideshow, text caption animation, or Ken Burns pan/zoom effects.

Shareware - 2
• (Ken Burns Effect: The feature enables a widely used technique of embedding still photographs in motion pictures, displayed with slow zooming and panning effects, and fading transitions between them.) – please see http://www.youtube.com/watch?v=nNTiyRDhlRY
• Shareware is not Open Source Software.
新 跃 大 学
Open Source Software
• Computer software that is available in source code form for which the source code and certain other rights normally reserved for copyright holders are provided under a software license that permits users to study, change, and improve the software.
• Open source licenses often meet the requirements of the Open Source Definition.
• Examples: Linux (GPL version 2); Apache Web server software (Apache License version 2)
• Repository: http://sourceforge.org
• Open source software for Windows

Software as a Service (SaaS) - 1
• Started with sales force automation and then customer relationship management (CRM)
• Now, it has become commonplace for many businesses tasks, including:– computerized billing, – invoicing, – human resource management, and – service desk management.
• Example: SugarCRM:– www.sugarcrm.com– Free Trial version; Buy Now version
新 跃 大 学
Software as a Service (SaaS) - 2• Benefits:
– Save money by not having to purchase servers or other software to support use
– Focus Budgets on competitive advantage rather than infrastructure
– Monthly obligation rather than up-front capital cost
– Reduced need to predict scale of demand and infrastructure investment up front as available capacity matches demand
– Multi-Tenant efficiency – Flexibility and scalability
• Risks:– SaaS provider company may fold up– No “law” to prevent such risks
新 跃 大 学
Software as a Service (SaaS) - 3
• Typical examples of SaaS Application Software include: – CRM, – ERP, – Project Management, – Retail Point of Sale (POS), – Banking, – Insurance, – CAD/CAM, – Word Processor, – Spreadsheet, – Database applications etc.
新 跃 大 学
Software as a Service (SaaS) - 4
• Can you think of a SaaS application software which is free?
• SaaS applications can be developed entirely from open source software.
新 跃 大 学
The Reality – Mix and Match
• Open Source Software + Software as a Service – Example?
• Open Source Software + Trial Software – Example?

Virtualization using Virtual Box - 1
• Virtual Box from SUN (now Oracle)• Allows other operating systems to be
mounted:– Microsoft Windows– Solaris– BSD– IBM OS/2
– Website: http://www.virtualbox.org
新 跃 大 学
Virtualization using Virtual Box - 2
Virtualization can be used in the following ways:1. Multiple OS’s on one system.2. Go green!3. Develop a project or a website in virtual
space first.4. Software testing and evaluation.5. Migration from one physical machine to
another without loss of service.6. Backup and recovery.7. Training: use virtual machines to train your IT
staff.
新 跃 大 学
Virtualization – other examples
• KVM / QEMU
• XEN

Raspberry PI - 1
What is it?
It is a credit-card sized computer that plugs into your TV and a keyboard.
It is a capable little PC which can be used for many things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video.
Why do they want to do this?
It is developed for the purpose of getting children all over the world to learn programming.
