Linux, programming, computers and life

I’m desperately looking for online calendar. Features i need, more or less sorted by priority (1st is most important) are (i’m not writing here the basic stuff)

1. Recurrent events. Yes, i tend to forget birthdays
2. Reminders - email at least, other creative options like RSS & Jabber are also appreciated
3. Ability to share the calendar with some other person
4. Standard files (ical?) import/export
5. Convenient - AJAX would be nice

Suggestions, anyone? I happen to know about kiko, airset, planzo and calendarhub.

Update:
Only kiko and airset support recurrent events, my number 1 - they become best so far. Way to go! Import is probably next great feature (for kiko), airset has this already. Thanks a lot for the comments.

Other suggestions, anyone?

I just discovered meebo - a free AJAX IM client - currently supporting jabber, google talk, icq, msn, and aim. I use jabber, which is superset of all the others, so it’s more than enough for me.
Great interface, simplicity of use… Of course, some features are missing, but it’s first cool web-based jabber client i have seen.

Today we’ll talk about archiving files in Linux.
“The Unix Way ™” which is Linux way also is: each program must do only one thing, but do it good.

There’re 2 types of programs for archiving:

1. put a lot o files in one file - tar we’ll talk about it in the next lesson
2. shrink/un-shrink one file - gzip, bzip2, compress

There’re 3 programs to shrink files: gzip (which is the default choice), bzip2 (which is the best compressing) and compress (which is old and generally not used). Of course, there’re programs like unzip, unrar, etc’ - which work with other format but I’ll not speak about them in this lesson. compress also will not be mentioned since it’s not generally used.

In order to shrink ‘file.smth’:

gzip file.smth

bzip2 file.smth

In order to un-shrink use:

gzip -d file.smth.gz

bzip2 -d file.smth.bz2

As you see, you can understand what the file format is based on the extension.
