Calendar or TODO ?

Today I found myself using iCal for the first time during last three to four weeks. And it looks like a trend already.

I'm not using calendar any more. I have no need for it. Everything is going to my TODO list. Think about it. Every note in the calendar should require some action, otherwise, it's not worth noting it. Birthday? Send a gift. Meeting? Make sure to arrive in time.

Well, the day representation in TODO is often loose to calendar, however, with things like TeuxDeux, it's arguable.

And you still keep the day on schedule.

So what about you?

P.S. Well, I'm cheating a little bit. I still keep the availability notes for people other than me in the calendar, to make sure that I can adjust my upcoming plans according to theirs schedule as well. However, I should find the solution to this problem shortly, too.

Scalability at Facebook

Facebook has grown into one of the largest sites on the Internet today serving over 200 billion pages per month. The nature of social data makes engineering a site for this level of scale a particularly challenging proposition. In this presentation, I will discuss the aspects of social data that present challenges for scalability and will describe the the core architectural components and design principles that Facebook has used to address these challenges. In addition, I will discuss emerging technologies that offer new opportunities for building cost-effective high performance web architectures.

Jeff Rothschild (VP of Technology at Facebook) talks about scalability at Facebook. Jeff has a long history in IT and was founder of Veritas. Click on "click here for webcast" to see the recorded video from the lecture.

Anybody tried such experiment

Please look at this page of Harvard Business Review - October 2009

I found this at Harvard Business Review - October 2009 (Page: 36). I thought you would enjoy reading this, too.

While I can't say I disagree that quick but effective nap time helps a lot to restart and get you back on track, I have doubts about how well could it be used on the job.  How many people would start taking naps and would keep beyond the reasonable time for that?  Do you need to make clear that your nap is limited to 30 minutes?  When you put limits on napping allowed wouldn't it mean that you can take 30 minutes off (not necessary for napping) and do what you wanna do legally?  Would the naps be that effective when you falling asleep with a ring in your head that you can't go beyond the 30 minutes limit?  Etcetera.

Personally, I don't like to take naps.  I mean, sometimes I feel that I need to, but I never do.  It just feels a little bit uncomfortable for me.  This might be just a mindset though.  However, naps really differ.  Sometimes you wake up full of energy and ready to fight, sometimes you wake up with a feeling that the rest of the day is screwed up totally now.  Who knows.
