Speaker 1: I like to optimize my life.

Speaker 2: Matt Oubani is a regular tea writer who can't stand

3
00:00:04,440 --> 00:00:06,840
Speaker 2: waiting around on the platform for the next train, so

4
00:00:06,880 --> 00:00:09,120
Speaker 2: he used his computer science degree in a little critical

5
00:00:09,160 --> 00:00:11,400
Speaker 2: thinking to make a device that tells him exactly when

6
00:00:11,440 --> 00:00:12,960
Speaker 2: he needs to leave his home to get to the

7
00:00:13,000 --> 00:00:14,840
Speaker 2: station as soon as the train pulls in.

8
00:00:14,960 --> 00:00:18,440
Speaker 1: The NBCA publishes real time schedules for the trains. I

9
00:00:18,480 --> 00:00:20,599
Speaker 1: just pulled down that data plug in how long it

10
00:00:20,600 --> 00:00:23,520
Speaker 1: takes to get from my apartment to Charles MGH, which

11
00:00:23,560 --> 00:00:25,440
Speaker 1: is my station, and just tells me when to leave.

12
00:00:25,520 --> 00:00:28,320
Speaker 2: It's pretty simple. A computer chip and a cheap little screen.

13
00:00:28,080 --> 00:00:30,600
Speaker 1: And right now it's telling me to hurry. The program

14
00:00:30,640 --> 00:00:32,800
Speaker 1: figured out that if I don't make this train that

15
00:00:32,840 --> 00:00:35,040
Speaker 1: comes in five minutes, I'm gonna have to wait another

16
00:00:35,120 --> 00:00:36,280
Speaker 1: ten minutes for the train.

17
00:00:36,479 --> 00:00:38,360
Speaker 2: Own A Bany says he doesn't intend on making the

18
00:00:38,400 --> 00:00:40,440
Speaker 2: devices for profit because it would rob people of the

19
00:00:40,440 --> 00:00:44,320
Speaker 2: opportunity to tinker around in their own lives. Jeremy Russ WBZ,
