Day 5 / 300 - Today we learned in the Haskell Challenge:
- Everything is a function
- Function composition is important in Haskell
- Functions look lean compared to TypeScript
- Floating point precision is bad! Yuck! (0.1 0.2 or 0.2 0.4)
- Tabs are bad (and my Neovim config is bad too)
- Everything inside a function is an expression
- A function without parameters is called a definition
- Recalled referential transparency from Day 2
- Type definitions are still not very clear to me (why does :t 5 return 5 :: Num a => a but :t "a" returns "a" :: String and not something like "a" :: String a => a?)
Thank you again for your support to everyone who joined me - I hope to see you next time!
Take care!

Day 4 / 300: Yesterday was exciting. I haven't made much progress, but I explored many concepts. Observations and questions from Day 4 of the Haskell Challenge:
- Distrobox export for ghci is broken on host
- Prefix functions can be used as infix
- But how to use infix as prefix functions ("*", "/", and " ")
- The arithmetic operator `/` isn't the same as the function `div`
- Negative numbers always require parentheses when used as arguments
- Use `not` for negating a `Bool`, but `/=` for a negated comparison. But `not True == False` works fine too
- Error messages are hard to read and understand
- `succ "a"` causes an error, but `succ 'a'` works as expected and returns `'b'`
- `max` and `min` also work on chars I did a lot of experimenting and didn't progress much in the book

Take care!

Day 3 / 300 of the Haskell challenge was all about setting up my development environment. Read about my journey, my thoughts, and learnings in the blog article.
I now have a working Neovim installation wired to the Haskell Language Server (HLS).
Ready for Day 4!

When working on a side project, itβs really a downer when you pick it up after 1 years and the first thing you have to do is spend days on library updates and migrations.
Well, not with Elm. Elm is feature complete, and you can pick up the code where you left it 5 years ago.
Isnβt it neat?

Day 2 of the Haskell Challenge. Today I mostly focused on understanding what 'referential transparency' means, in both the computer science and linguistic context. It was confusing at first but I am sure it will eventually click within the next 298 days.

I tried to break it down in a short video, if I misunderstood some concepts feel free to correct me as I am here for the learning and not the teaching. Thank you and take care!

My thoughts and learnings after my first day (but not first attempt) of learning Haskell. I had fun streaming this live, thanks so much to everyone who joined me today!
Let's do this for real. I can't wait to look back on this day after reaching day 300!

Haskell learning update:
- [1,2,3] is syntatic sugar for 1 : 2 : 3 : []
- pattern matching in Haskell is hard to get used to (for me)
first :: [a] -> Maybe a
first [] = Nothing
first (x:_) = Just x
but (x:_) is pretty cool
- guards combined with pattern matching is fire

It seems like the whole world is building things for agents. Where was all this creativity when it was about building things for humans? π€

AI psychosis is real? Fascinating how convincing those people can be, about AI taking our jobs.
Sometimes I wonder whether I have a psychosis, or if they have visions. Nor are healthy.

No doubt, there will be a shift in society, like there has always been. Jobs will go and others will be created.
Bus drivers may become "remote bus driver supervisors" making sure AI buses don't crash into walls.
Or developers becoming "AI agent supervisors" (fairly doubt).
So many possibilities.

One thing is sure: I will always have a job, simply because I find it too boring not to work.
I was and stay open minded to anything and am not attached to what I am currently doing at all π€·

How can I discover live stream creators on X? Is there a "Live now" tab somewhere that I missed?

The more time I spend on X, the more I realize how little people actually have to say. But everyone talks a lot.
