Ubuntu 10.04 (Lucid Lynx), Asus Eeepc 901 and wireless networking

March 5, 2011 10 comments

For the record: Ubuntu 10.04 (Lucid Lynx) is working great on the Asus Eeepc 901. Only the support for the RaLink RT2860 wireless chip is not that great, sometimes the system refuses to connect to a wireless network.  The best approach seems to be installing the backport package that brings a newer version of the driver:

sudo apt-get install linux-backports-modules-wireless-lucid-generic

or when the PAE kernel is being used:

sudo apt-get install linux-backports-modules-wireless-lucid-generic-pae

Connectivity is much better for me with the updated driver.

Please do not throw salami pizza away

July 11, 2010 Leave a comment

Remembering the seven layers of the OSI model for communications and computer networks can be confusing. I like the humorous way of remembering the names with this memorable sentence:

  • Please
  • Do
  • Not
  • Throw
  • Salami
  • Pizza
  • Away.

The first letters map to the names of the different OSI layers:

  • Physical Layer
  • Data Link Layer
  • Network Layer
  • Transport Layer
  • Session Layer
  • Presentation Layer
  • Application Layer

This works at least for computer people enjoying salami pizza. As a sidenote, Layer 8 is not part of the standard OSI model, although it can be important for troubleshooting problems in the real world.
