[Jason Kottke](http://www.kottke.org) has an interesting write-up about how he envisions the future of the OS and the Web. The gist of his post can be summed up in the following points:

1. The OS can be made irrelevant by people writing for another OS, let’s call it WebOS.
2. People now only need to code for one platform (Java, anyone?)
3. A local web server on the client machine will mean that an app can continue on working even if it’s offline (think local app for Gmail, etc).
4. When users are back online, the app will synchronize itself with its online counterpart. Think adding Flickr pictures locally, and then uploading them.

The OS is still there whichever one it is, but it is no longer going to lock-in developers to only developing for that OS. One of the things Jason is saying is that people will no longer need to write for 3 OSes but for just one OS. This sounds just like “people will no longer have to write for 3 OSes but for just one platform: Java”.

Jason has already outlined some of the problems he envisions with this approach, such as web apps accessing local content on your hard drive. Java applets have solved this problem for a long time by using a sandbox model. The only problem is that these applets have to be downloaded and run locally for them to work. A WebOS app, however, will run both locally and remotely, it will live on your local hard drive and perhaps a sandbox model will help there as well. Are vulnerabilities detected in these local apps any more dangerous than vulnerabilities for remote apps? Perhaps there isn’t much different because at the end of the day, a security hole is the same thing whatever app it affects. However, I suppose a local security hole can do a *lot* more damage than a remote one.

Some other suggestions like: “Read newsfeeds from bloglines locally” sound no different to NetNewsWire, FeedDemon or SharpReader, etc. These are all locally accessible feed readers which, when online, update your subscriptions, etc, otherwise they work fine when offline.

I think, as [Paul Graham](http://paulgraham.com/) said, a WebOS will allow totally new kinds of applications to exist and we don’t know what they will look like at all. So this is definitely an interesting space to watch.
Some great examples of new ways of using the web are: [Backpack](http://www.backpackit.com), [Basecamp](http://www.basecamphq.com/), [Gmail](http://www.gmail.com) and [Google Maps](http://maps.google.com). Another up-and-coming app is [Hula](http://hula-project.org/Hula_Server) which has been open-sourced by Novell and is being actively worked on by many GNOME hackers. If you want to see a demo of how the future of web-calendaring might look like, take a look at [this](http://www.nat.org/2005/august/#Hula-Web-Interface) amazing demo on [Nat's](http://www.nat.org) blog.

In other news, I would love to get my hands on one of [these](http://joi.ito.com/archives/2005/08/25/wearing_firefox.html) [Firefox](http://www.getfirefox.com) T-shirts that [Joi](http://joi.ito.com) managed to pick up from the [Mozilla](http://www.mozilla.org) offices. I have ordered quite a few T-shirts from [ThinkGeek.com](http://www.thinkgeek.com) in the past, and I will order one of these if they stock them someday.
