Virtual and non-materialistic

What is the difference between the virtual world and the non-materialistic world?
I remember someone, who introduced into the computer science world, by declaring it non-materialistic. Software, i.e. "code, text, thoughts and time", is nothing. It's nothing less than nothing but it doesn't seem to be a lot more. It's not a table or chair you made by your own hand, it's not a car you drive around, it's not the hair cut by a hairdresser and not the burger you bbq-ed on your very own.
So what is it? It's nothing you can show, it's nothing you can take with you...
Or is it?
Today we can make software we put on our mobile and show it around. It can take a lot of time to produce it, it can make us proud. But still, it's nothing without a medium.
It's not easy to depend on a medium and be proud of it. If you show someone your mobile with your first J2ME application they might see the mobile, not the software you made. If you show someone you display and say you made it, how trusts you? I wouldn't think anybody I know can make a display.
But on the other hand, what are authors and journalists? They write books. Do they make the books in a way, do they produce the paper it is on? Do they glue the papers together to form a book? And journalists on TV, do they make the news? No, they just talk about it!
Perhaps, computer science (in this case, the software part only) could be a lot more satisfaction if it was more talked about than made.
We should try.

The network in the pocket

The day before yesterday I watched the movie "The holiday" with my gilfriend. It's about two girls making a holiday leaving their work, their friends and everybody else at home.
But though, they still leave their mobile and blackberry turned on.
Now imagine, making a holiday to leave everybody somewhere else but leaving your mobile on. Doesn't make sense, does it?
Ok, but everbody know, that movies usually don't claim to be logic.
What I thought, once again, is that in our modern world, we don't have to care about the place we are, we just have to care about the time it is. No, not even that. It doesn't matter what the time is because it's a different time depending on where you arem which timezone. So it's more interesting think in timespans than in points in time. Even more, what is a timespan, anyway?
One might think that 3 minutes is a timespan. But what the hell, who needs 3 minutes for something (despite the tea, of course). Perhaps we should start thinking in bytes we have transfered, perhaps in words we spoke, perhaps in something we ourselves think is good.
Ok, gotta go. We'll meet tomorrow, same time, same place (whatever this may mean).

Watching the web

Performing my studies, I have to work on an article about Mobile Social Networks. I even started for social bookmarking at furl.net although I nearly never used bookmarks.
What for should I use bookmarks? I use more than three different PCs and Operating Systems. Even if I used the same browser everywhere, it would be hard to keep the bookmarks up-to-date ( I know, I tried using POP3). Let's see if social bookmarking helps or even lets productivity grow.
