On Tuesday we will do some in-class software development. Please coordinate with your partner so that every pair has at least one laptop in class. Thanks.

I have modified C — Exploring Your TAHBPL Some More to fix a mistake, clarify a bullet, and explain some terminology that may have gotten lost in the lecture. While this terminology isn’t all that important, clear terminology is always helpful when all parties accept and understand it.

Industrial people are slowly recognizing the downside of ticket-driven software development. Considering reading the Jon Evans’s blog post to get a sense of what these people are getting at.

netcat (abbreviated nc) is the best way to manually send JSON information from your shell to your server:

    [login-faculty] $ cat test-input.json | nc login-faculty.ccs.neu.edu 45678

This command connects the cat command with the nc command via a pipe, a combination that is also available on your macOS. Specifically it sends the content of the test-input.json file to nc, which in turn transmits it to the computer with the IP address login-faculty.ccs.neu.edu at port 45678 (if all of you use 8000 on the same computer, bad things will happen).

Here is a demo screen shot from my computer:

In this example, I am using nc to send JSON from login-faculty to a computer called antarctica, also on the ccs.neu.edu network.

In the right shell window I start ./C up, waiting to connect with a single client. Then in the left window I first display the content of the test file to the shell, before I use the command combination from above to send it to the “server” in the right window. As soon as the server has done its work for the client, it shuts down—of course after sending back the correct answer to the client, which displays the answer in the shell.

Please prepare a letter-size sheet of paper by folding it lengthwise, writing down the name of your favorite programming language on one side and placing it in front of you on your desk. ~~ You will get the chance to build a large code base in this language so that the instructor’s taste in PL won’t inhibit your amazing programming skills.
