Post-It Story

Post-its Office

Post-it are a revolutionary product and you can use them to be creative and innovative in other fields. But in the last years I’ve heard a few stories from different friends, teachers and conference speakers, about how post-it was originally created. Maybe everyone adds a little of their personal taste to the story just like any urban myth, but I think this is the real one:

Most people love them.

But Post-it® Notes were not a planned product. No one got the idea and then stayed up nights to invent it. A man named Spencer Silver was working in the 3M research laboratories in 1970 trying to find a strong adhesive. Silver developed a new adhesive, but it was even weaker than what 3M already manufactured. It stuck to objects, but could easily be lifted off. It was super weak instead of super strong.

No one knew what to do with the stuff, but Silver didn’t discard it. Then one Sunday four years later, another 3M scientist named Arthur Fry was singing in the church’s choir. He used markers to keep his place in the hymnal, but they kept falling out of the book. Remembering Silver’s adhesive, Fry used some to coat his markers. Success! With the weak adhesive, the markers stayed in place, yet lifted off without damaging the pages. 3M began distributing Post-it ® Notes nationwide in 1980 – ten years after Silver developed the super weak adhesive. Today they are one of the most popular office products available.

FriendFeed – my #1 source of information

This may be a controversial article, and many people may disagree with me, but it reflects my opinion on why FriendFeed is the ultimate tool for keeping me updated on the Internet.

FriendFeed Logo

My experience with FriendFeed started a long time ago, but only in the last couple of months I’ve started to using it more extensively. The main reason is because of the redesign the company did on the service. Yes, this new design (with some minor new functionalities) made me fall in love with the application. You can get a better feeling of it at VentureBeat: FriendFeed’s redesign combines publishing and IM better than Facebook or Twitter.

Twitter vs FriendFeed

I have to say that I’m a huge fan of Twitter and that’s probably the reason I don’t blog more often. But Twitter has become a bit of a problem to me. I like to follow people that I think that are relevant to my interests, but I also like to follow back people who think my tweets are interesting. I could well follow about 50 different individuals to keep me updated about web stuff, but when I passed the 150 followers my stream become unreadable and full of non-interesting information. I could use some Twitter client to organize all those people into groups, but I’m a huge fan of open-source and most of those apps are built under Adobe Air.

Where does FriendFeed fills in?

FriendFeed has some unique features that solves my problems. On FriendFeed you can add all you social profiles, so when you follow someone you don’t subscribe only to his Twitter account but you can also see their YouTube favorite videos or Flickr photos. You can also sort your contacts in different groups and you don’t need to refresh your browser for updates. You even don’t need to click on external links to watch videos or photos. Another big advantage is that you can comment others content and consequently do a better track of conversations. You are not limited to 140 characters and you can integrate your account with all others social networks such us delicious or Facebook. FriendFeed also has some other really sensible and useful features such as lists (a specific list of friends or people you subscribe to). You can get it all at the help page.
With FriendFeed you can get all the juice of an occasional chat.

The verdict

Right now I’m using FriendFeed has the main source of information and I see some growth in the number of followers on Twitter. If you haven’t tried already, spend a few moments on it and give it a try.


Last week I’ve attend to Cloudviews 2009 – Cloud Computing Conference at ISEP in Oporto.

It was with surprise that I realize this conference would take place in my town because most of the international events happen in Lisbon. Maybe because the team at Cloudviews is somehow related with ISEP.
The mains theme of the conference was “To Cloud or not to Cloud” and all the speakers tried their best to answer this question.

Cloudviews - Cloud Computing Conference 2009

In general I think the conference was well organized but I was hopping to see more people attending it. Some of the speakers were from well known companies in the IT industry like Salesforce, IBM, Amazon or even OpenID and got surprise when I realize this was a free conference with free lunch (very nice btw) and free snacks.

I just subscribed the Cloud Computing Daily Views and I want to congratulate the team for their dedication and talent. Hope to see you in the next year!

And quoting Gerrit Huizenga

The era of cloud computing is just beginning.
