Sometime in mid-December I set out to create problem sets for the book. My friend Nizar Kezzo offered to help me write the exercises for Chapter 2 and Chapter 4 and I made a plan to modernize the calculus questions a bit and quickly write a few more questions and be done in a couple of weeks.

That was four months ago! Clearly, I was optimistic (read unrealistic) about my productivity. Nizar did his part right on schedule, but it took me forever to write nice questions for the other chapters and to proofread everything. After all, if the book is no bullshit, the problem sets must also be no bullshit. I’m quite happy with the results!

noBS problem sets: letter format or 2up format.

Please, if you find any typos or mistakes in the problem sets, drop me a line so I can fix them before v4.1 goes to print.

Tools

In addition to work on the problem sets, I also made some updates to the main text. I also developed some scripts to use in combination with latexdiff to filter only pages with changes. This automation saved me a lot of time as I didn’t have to page through 400pp of text, but only see the subset of the pages that had changes in them.

If you would like to see the changes made to the book from v4.0 to v4.1 beta, check out noBSdiff_v4.0_v4.1beta.pdf.

Future

Today I handed over the problems to my editor and once she has taken a look at them, I’ll merge the problems into the book and release v4.1. The coming months will be focussed on the business side. I know I keep saying that, but now I think the book is solid and complete so I will be much more confident when dealing with distributors and bookstores. Let’s scale this!
