Daily del.icio.us bookmarks

I was pointed to a couple of outstanding web services that I will talk more about later. For now here are the links:

Than there was this excellent flash animation that gives a good idea of Atlantic hurricanes – their strength, timing, and pathes. Thanks to Lev for this one.

A good set of reading about blogging – why and how people do it. Also has a couple of interviews with famous bloggers.

Calendaring issues solved with AirSet

I’ve been looking for a tool to do shared calendaring for some time now. I went through manual editing of text files, ical, Korganizer, RSSCalendar.com and some other tools that I don’t remember anymore. None of these provided all the functionality and comfort that I needed. So, I used neither one of them.

Today, I finally came across a tool that looks very promising. One of the comments to this post in Alexandra Samuel blog suggested AirSet.

I tried it and it was love from the first sight! AirSet provides a free online service for managing and sharing of calendars, contact lists, and web links. It features flexible access control facilities with user and group management. Sharing of information can be neatly controlled and can be utilized either via RSS feeds or via AirSet web service.

I liked it so much that I immediately registered and created my public calendar. Check the “Calendar” link at the navigation bar at the top of the page. There you will find my public calendar and a link to the RSS feed with items for the next 30 days.

I foresee a lot of popularity for AirSet in the near future. Congratulations to the development team for a really nice service. Let’s see how stable it is.
