One thing I remember liking in this post was his personal homepage (a little further down). There has been a recent HN discussion of Glance, a personal dashboard, but Wolfram's seemed more effective.
If I could visually persist 3 lines of a terminal in my vision, and then otherwise use the functionality of a cell phone with ear buds with microphones, I think I could do 60% of my job while walking around in the forest behind my house. Most of the time I wouldn't need the terminal.
Do my cohorts, who have drifted into positions of tech lead, and then onwards as technical mentors to younger dev teams, find the same? I know I betray my communication style by admitting I don't need to see the screen; I prefer to see their world through a mental model built by words and sensing body language through tones and pauses. I'm not even sure I'm in the right line of work most days, at this point.

Overall impressive.-
