If you've ever tried to test a stateful app in QuickCheck, Hedgehog or any other property-based testing library you'll know it can be seriously difficult! Check out this tutorial for a simple way to test stateful apps using Hedgehog. jacobstanley.io/how-to-use-hed…

@_justanotherdot We irreversibly updated a core library in the process. That typing thing you were doing can’t be continued without fixes to 6 downstream projects. I hope you can produce said fixes in another place where typing still works.

Oh were you typing? Sorry it’s time for some software you barely use to get updated.

“being careful” is a way better strategy for avoiding bugs than like, CI

@mxswd When are you upgrading your name Ultrawell?

Ryan’s imposter syndrome is actually legit. Please don’t read this. Seriously though, he knows his shit, if you care about performance don’t miss this one.

Fast systems aren’t built by accident. Wasting days making random changes is no way to approach performance tuning. I’m writing a book on performance in Rust equips you with the skills you need. justperf.dev

Weird that we'll check you know how to reverse a linked list on a whiteboard but not whether you can google effectively.

@mwotton there isn't really a good way to do this at the moment unfortunately

@jacobstanley hey, is there an idiomatic way to assert that a hedgehog test should fail? I'm testing a hedgehog extension and I want to assert that it finds the problem.

Be lazy. Do it in batches. Run many things simultaneously.

@thumphriees @_justanotherdot 100% with you on this one I use a tree tab but wish it was better! I need fzf for tabs Also browsers that can page out old stuff, my Firefox gets so slow it feels like a virus ridden Windows

tfw when the domain renewals roll around from last year's failed ideas

@ploeh @nikosbaxevanis @bender2k14 It's a good point though, don't other type class signatures appear? If you hoogle for "(a -> b) -> [a] -> [b]" it shows fmap, I don't see the difference.

@ploeh @nikosbaxevanis @bender2k14 you could argue that actually using this is a bad idea 😅

In functional programming, is there a well-known name for the function fun f a -> f a a? (That syntax is F#)
