It's 08:38 am. Here with me I got a glass of cold brew coffee while I'm typing this email. Let's jump into the good stuff!
From the Blog
The functional programming post this week is a remix of a talk I gave at my company. It is also the way I design and structure code nowadays regardless of the programming language.
Decomposing Features into Pipelines – Code and pray when devising a solution is not the best approach. The exploration needs to start in problem space.
The essential skills post covers one of the best pairing sessions I had in my career. It was the first time I noticed somebody trapped in Einstellung so clearly. I remember gifting Radek a paper explaining more scientifically why he got stuck on that bug. I also wrote about Einstellung last week.
The Secret to Getting Unstuck when Investigating a Bug – When Radek asked me to pair on investigating a bug I was skeptical. But I had something he lacked: ignorance.
From YouTube
I dug out the first ever script I've written in Haskell. Probably not the greatest code but I found some interesting nuggets. Plus, I realized how types helped me get up to speed on how the script worked. Had I written it in Bash it would have been a disaster.
Tidbits
git log -G REGEX to look for differences whose patch text contains added/removed lines that match REGEX. Click here for a visual example.
git log -S STRING to look for differences that change the number of occurrences of the specified string (i.e. addition/deletion) in a file. Click here for a visual example.
-- (&) works as | in Bash
1 & (+ 1) & print
-- 2
-- $ vs <$>
(+ 1) $ 1
-- 2
(+ 1) <$> [1, 2]
-- [2, 3]
The Most Epic Programming Talk Ever
As promised on Twitter, here it is. I hope it's going to be as mind-blowing and inspiring for you as it's been for me!

The best part of email is that interaction is personal and one button away. So please reply with your thoughts, let's learn from each other.
Yours truly,
