Macbook Air runs at more than 100% CPU every other time.

Macbook Air is a nice lightweight notebook, but I bet you didn’t expect it can serve as a room heater in those long winter nights. It has a bug that makes Air’s kernel_task to use up to 200% CPU when it is actually idle.

This is Air-specific issue only, haven’t seen it on other notebooks but witnessed on different Airs. I am not sure about the latest Air revision, but previous ones was plagued by this and this issue is not resolved still.

Arghhh!

Internet Explorer 8 keeps traditions alive.

WebROaR - new ruby application server. Going to give it a try any day now.

There are 2 transfer modes on ftp. I never knew what’s that for until today.

ascii - this is the default and transmits seven bits per character
binary - the binary mode transmits all eight bits per byte and thus provides less chance of a transmission error and must be used to transmit files other than ASCII files

Today is 2009 and we can afford all the 8 bits, use binary mode all the time.

Rails tip: Don’t do excessive validates_associated on has_many associations.

has_many associations are validating by default (:validate key):
