I’m not an overly paranoid person and think some of the people who feel the need to delete their cookies regularly are probably taking things just a little too far. If people are tracking me around the web and serving adverts I might actually be interested in - fair play to them! I have nothing to hide and nothing to worry about.

However I didn’t realise that Flash provides a much more dangerous type of cookie that really needs to be addressed.

This Local Shared Object can:

• Stay on your computer for an unlimited amount of time
• Store 100 kb of data by default, with an unlimited max
• Couldn’t be deleted by your browser
• Send previous visit information and history, by default, without your permission

The big thing I take exception to here are the last two points. Firstly I believe every technology should give the user the ability to opt out, for cookies the option to delete should be readily available even if for the most part it’s only used by a minority. But the second point is truly wrong - this kind of data should be limited as it is in other technologies such as JavaScript.

Come on Adobe just give an opt out button on the next version of Flash player or perhaps just make security settings a little easier to find for your average user?

Microsoft’s Silverlight seems to be gathering steam and is getting lofty predictions from industry monitors that it’ll triple its use within 18 months.

It’s major competitor, the current undisputed market leader, is Adobe Flash but I believe in the long run Silverlight should at least start to give Flash a run for it’s money which is only good for encouraging innovation even more.

Comparing Flash against Silverlight isn’t really fair we should be looking at Adobe Air which gives a whole platform to work with in a similar way to Silverlight.

I have to agree with the predictions from the article I can see Silverlight adoption growing rapidly. However I don’t necessarily see Flash market share suffering hugely; at least at first. Generally Flash is a design tool (I accept it can do more but ActionScript isn’t a good development language in my opinion) and I can’t see the Flash lovers changing over to Silverlight quickly or at all. Flash does what they need - if it ain’t broke why fix it?

In which case how is Silverlight going to take off? Well it provides an amazing tight development platform - server-side and client-side coding along with multimedia all tied in together. The idea of XAML is very exciting allowing the development of user interfaces that just weren’t possible before. Also because it’s the next step for the .NET framework the great number of existing .NET developers that will adopt it causing it to grow quickly. Also Microsoft have been very clever here as Silverlight can be treated as a development platform or a design platform depending on your strengths and therefore the software package you would use therefore hoping to steal the Flash market. Finally Microsoft are truly trying to make Silverlight cross-platform and cross-browser to maximise the market potential in a similar way to Flash.

I for one will eventually move onto the Silverlight platform - I’m currently monitoring it’s success to ensure the community around this new technology is mature enough to support it fully.
