I started my morning with some cowboy coffee; which is coffee brewed in a saucepan, since I seem to have misplaced my aero press, as I listened to Go for beginners, and discovered Gophercises, a set of coding exercises in Go aimed at people who’ve done a few tutorials but have kinda lost steam. I felt like that described me, so I’ve decided to tackle these exercises while journalling my progress and learning in this blog.

/I have a peculiar writing style because I write in tandem with coding, so there’s a lot of tense switching, so apologies in advance. All comments and criticisms are encouraged, no matter how harsh or abrasive, as long as they are constructive!/
