Hello scala, my old friend
I've come to take you home again
Because a feature slowly creeping
left me plagued with doubts and weeping
and the version that was tagged in the repo
just has to go
it lacks the signs of soundness

On sleepless nights I hacked alone
applying ant and other tools of stone

I have two user accounts set up on my mac. User drew I use for most things, but if I'm making a screencast I'll switch to the demo user. I know that the demo user has a clean desktop, and the font size is larger than usual in my terminal and text editors, making everything a bit more legible when capturing the screen. When I record a screencast as the demo user, I save the file to /Users/Shared/screencasts. As I understand it, the /Users/Shared directory is supposed to be accessible to all user accounts on the mac. If I created and saved a screenflow document as the demo user, I should be able to read and write that file when logged in as user drew.

That was the theory, but it didn't always work out that well in practice. I would occasionally find that a directory was only writable by one user or the other. Perhaps I'd open a screenflow document as user drew and attempt to export the video to the same directory, only to find that the directory was owned by demo, meaning that I couldn't cr

Haskell Style Guide for Elm

Goal: a consistent style throughout all Elm projects that is easy to read and produces clean diffs to make debugging easier. This means valuing regularity and simplicity over cleverness.

Line Length

Keep it under 80 characters. Going over is not the end of the world, but consider refactoring before you decide a line really must be longer.

Union Types

If Elm community is going to begin referring to "union types" instead of "algebraic data types" we should think about how that will work in practice. What discussions will we have? Will we find ourselves in awkward spots trying to explain things?

The following question/answer pairs simulate things I'd expect to see in a world of "union types". The pairs are grouped by what background I expect the questions to come from so we know the subtext. I have also added some meta comments in italic to explain my phrasing.

One thing to consider is that a lot of learners will not have a person to ask, so the path to arriving at these answers needs to be easy if you are just searching online.

Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:
