Nebulosa del Cangrejo / Crab Nebula
domingo, octubre 25, 2009

Just reblogging the content of the Photo of the day from NASA, as it's one of my prefered objects in the sky.

This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. The filaments are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The above image, taken by the Hubble Space Telescope, is presented in three colors chosen for scientific interest. The Crab Nebula spans about 10 light-years. In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.

Sugarsync : keeping your key information in the Cloud
domingo, octubre 18, 2009

When I became a Mac user, one of my priorities was to find a way to move information efficiently between my PC and Mac, even if one of them was staying at the office and the other at home.

While I have a network drive ( Buffalo D-link ) which I can access from anywhere, I'm aware it may die one of these days and all the information would be lost, so I decided to give a try to one of the cloud-based storage services.

It seems that the two key leading services in this area are Sugarsync and Dropbox, in addition to the service from Apple.

As the Sugarsync systems supports Blackberry access in addition to PC and Mac, I decided to give it a try and registered for a free account ( 2 GB storage space ).

One more benefits is that they have clients for most OS both in computer and mobile device. Pc, Mac, Windows Mobile, Apple, Blackberry, Android...  all of them very intuitive and simple to use.

I've been using Sugarsync intensively for the last two months, storing there the key documents and presentations I'm working everyday so I can resend them easily while on the move or access them at home from my Mac computer ( powerpointing is a completely different experience when you have a Mac ;-)

The end result of this testings is very, very positive. Sugarsync gives me the confidence that my key files are backed up and even if a loose or forget my laptop I'll have access to my critical information from everywhere. Both my Mac and PC have an updated folders where the last version of my Evangelism presentations are stored, and resending to anyone or sharing a full folder is just a question of seconds.

In addition to this, I found Sugarsync a very useful service to share pictures with many people. In the past I used public folders in Flickr to do this, but this made the rest of my pictures to change their assigned web address, and most of the photo hyperlinks in this blog stopped working. With Sugarsync it's very simple, you just create a new folder, share it and send the link to as many people as you want.

As a summary, I'm loving my Sugarsync service and it's coming now to the list of the services I'd be ready to pay for if I really need more than 2 GB space. I had a look to Drop Box again, but I don't see a clear advantage why I should use it versus Sugarsync, so I'd stick to my sweet friend.

Updated to Snow Leopard
sábado, octubre 10, 2009

Some of you following in Facebook already know I moved to the bright side some months ago ( by the way one of the best decisions I've ever taken ).

Today I have updated my Macbook Pro 15" to Snow Leopard with no problems. All hardware works well, all software still works...

Very different experience than any Windows update in the past...
