It's true that compared with the scene when Unix started, today the ecological niches are fairly full, and fresh new OS ideas are harder to come by, or at least to propagate.

I've done a reasonable amount of travelling, which I enjoyed, but not for too long at a time.

A program designed for inputs from people is usually stressed beyond breaking point by computer-generated inputs.

UNIX is simple and coherent, but it takes a genius (or at any rate, a programmer) to understand and appreciate its simplicity.

I'm just an observer of Java, and where Microsoft wants to go with C# is too early to tell.

Twenty percent of all input forms filled out by people contain bad data.

... with proper design, the features come cheaply. This approach is arduous, but continues to succeed.
