KDE SC 4.4 rocks!

Montag, 18. Januar 2010

Challenges of the next

5 years

Montag, 18. Januar 2010

Move from

Desktop Apps to

Cloud Apps

Montag, 18. Januar 2010

Examples:

• Pandora / last.fm• Google Docs• GMail/Hotmail/Messaging• Flickr / Picasa• even Instant Messaging.

Chrome OS

• Offline Support • Native Code Support• Notifications• WebGL• “Security”.

Montag, 18. Januar 2010

Google doesn´t think that native destkop app are

less important.

Google think they are irrelevant in the next years.

Montag, 18. Januar 2010

Why ?

Montag, 18. Januar 2010

Surveyadvantages

Montag, 18. Januar 2010

The advantagesthe biggest advantage (imho) of cloud computing for users would be ubiqious presense of applications and data.

data can be accessed from everywhere (PC, laptop, girlfriend latpop, www)

You can delegate upgrades/backups to the service provider

No need to install software

easy interaction with other users

You don't need to worry about losing your work if your machine crashes

Montag, 18. Januar 2010

So a shiny happy new

world is comming ?

Montag, 18. Januar 2010

Is this trend good from a free

software perspective ?

Montag, 18. Januar 2010

Where is the place for classic Desktop applications like

KDE SC in 10 years ?

Montag, 18. Januar 2010

Surveydisadvantages

Montag, 18. Januar 2010

The disadvantages

the security of your personal data. Where are your files stores? By whom? In which legislation. user data might be not

encrypted

dependency on 3rd party infrastructure (hot spots, internet, lan)

hosting is highly non-trivial

too much ?

Montag, 18. Januar 2010

What can we doabout it?

Montag, 18. Januar 2010

Is it possible to combine the best of both worlds?

• rich desktop with rich applications instead of web apps• social• easy deployable• data under my control but accessable from every device.

Montag, 18. Januar 2010

What do we have to do?

1. Social2. Deployment / Access to applications3. Access and sharing of data

Montag, 18. Januar 2010

1. Social

Montag, 18. Januar 2010

Social DesktopBringing Social Features to Desktop Applications
