Weekly Review 17

My fifth weekly review is here. I am continuing to work on the third chapter of “How to prove it” book. I started to do a long distance walk.

Done on this week

“How to prove it“
I didn’t manage to finish the exercises in chapter three. However, I am not sad. Guess, why? Because I learned how to make the proofs, which is the main purpose of this chapter and the whole book, I think.
I am at the end of the fifth section of the chapter. The chapter has seven sections. Sections six and seven have fewer exercises then three and four, so I feel that I’ll finish the chapter on this week. Fingers crossed.
I found a new interesting activity, which is also useful. I do a long distance walking (well, if seven km is a long distance) and listen to an audiobook. So, on this week I walked around 40 km and finished to listen “О чём я говорю, когда говорю о беге”. Pretty nice book. After listening to the book, I felt the desire to run a marathon distance, I wish to do it at some point in the future.
Next book for my walking activity is written by the same author: “Охота на овец”.
The interesting talk about the extended functor family:
George Wilson − The Extended Functor Family
Handy one-liner bash, the command which joins the images. This is from ImageMagick software.
