Trouble Activating iMessage on an iPod Touch

I recently activated iMessage on an iPod Touch. Ran into the problem where the activation fails.

A little research on the forums led me to comments on the DNS server issue with a recommendation to use 8.8.8.8 as the IP address. Surprisingly, changing the DNS server to 8.8.8.8 resulted in my being able to active both FaceTime and iMessage.

I say surprising because I haven't seen any other DNS issues with the server I was originally using.


Unfortunately, in order to keep iMessage and FaceTime working I had to leave the DNS server address as 8.8.8.8. Changing the DNS server entry back to its original value resulted in iMessage working for a while but subsequently failing (presumably because the DNS entry needed to make iMessage work finally expired in the cache).

The Computer Scientist as Toolsmith

Every once in a while I have the pleasure of rediscovering an old article whose lessons have withstood the test of time. Two articles by Frederick P. Brooks Jr. entitled "The Computer Scientist as Toolsmith" pass this test.

Both articles appear under the same title. The first article was written in 1977 (reproduced in 1988); the second published in the Communications of the ACM in March 1996.

Unautomate Your Life?


I've talked about ZenHabits in the past on this blog. I am becoming dissatisfied with the posts on ZenHabits. In a recent post they discussed how to Unautomate Your Life.

Unautomate? Now they are making up words in an attempt to be clever. It's actually annoying.

(To be fair the ZenHabits post was by a guest blogger.)

Using Tinderbox to Explore Frameworks

Eastgate describes Tinderbox as a personal content assistant that helps you visualize, analyze, and share your notes, plans and ideas. It's an interesting application to use. One of the key benefits I've obtained from using Tinderbox is the exploration and use of frameworks.

The benefit of using Tinderbox to explore and use a framework is twofold. First, you gain insight into the framework by developing a Tinderbox document describing it. Second, use the Tinderbox document describing the framework to explore a problem using the framework. It is this second benefit where Tinderbox really shines.
