I've just gone through this process over the last couple of years. To be honest, the most effective learning tool for me was dedicating my free time for a little while to learning Haskell. It's a higher upfront cost but a huge pay

I think fp-ts exists because TypeScript is entrenched with a strong job market. If that weren't the case most users would just use something like PureScript.

Libraries like io-ts and zod take care of this for you. For io-ts for example you just need to define a type guard function that asserts "x is Y" and away you go, you've got a runtime codec; it knows how to "decode"

I struggled introducing fp-ts into my last team but io-ts was a much easier sell, as was fast-check. It's a lot easier to get buy-in when you can demonstrate that it will reduce bugs thereby improving the customer experience and reduci

I think that was replaced by Rectangle.

Something this doesn't tell you is that summers in London for example are awful because our homes have historically been designed to trap heat.

The unread count in the notification doesn't update if you view your emails not in the mobile app.

If the issues with it aren't too obvious you can trade it into Apple claiming it's in good condition. That's ethical as far as I'm concerned given the issue is their own fault.

Oh damn, who laid off their PS team? First I've heard of that.

I've successfully looked at commits years old to understand the context around a feature/bug that was confusing myself and a product owner. This context is where small, well-detailed commits come in so handy beyond just the initia

One could argue that the effectiveness of propaganda that stems from this viewpoint proves its premise. Whether that makes propaganda of any given form justifiable is another matter.

You have a container with `a` inside, let's call the container `m`. You have `m a`. You can provide a function with the type signature `a -> b`. With this we run the function underneath `m` and map `m a -> m b`. Concretely this m

How can you say it's easier for humans to reason about when your test subjects almost all exclusively got started in programming with imperative programming? It's a slightly biased data set.

Function application pipelines and function composition are closely related. Here's a "pipe" in Haskell: \x -> h $ g $ f x At a certain point you realise that in many cases seeing the `x` is not just useless but needless v

I've had a great experience learning Haskell with Exercism. Also unaffiliated.

Vanced is also really good. Supports YT Music too.

Perhaps, but I think it can be argued that it encourages more consumerism. The market for second-hand selling may encourage those sellers to buy more new. Fundamentally the idea of an everchanging fashion is problematic, not just environmen

I use offlineimap* which allows you to optionally sync in one direction. I'm not sure what happens if the remote emails are overwritten though. * https://github.com/samhh/dotfiles/blob/master/home&#x

All looks orange now, but "degraded performance" is a cheeky way to describe "everything is on fire".

The first R is reduce. The second is reuse. Our cultural obsession with fashion completely bypasses each of these.

PureScript's build system is very good (Spago), and the language is too, but it is tougher to learn than Elm veering much nearer Haskell.

This is definitely the best option in the TS ecosystem but it's not meaningfully implementing typeclasses from the perspective of the end user. There's no single `fmap` for example, instead you'll be using dedicated `Array.ma

Logically they're the same, they're isomorphic. It's just about ergonomics, readability, etc.

There are many application states in which `null` could mean "not got the data yet" and/or "there is no data". Just use an enum, it's much more expressive.

It can just as easily mean that nobody knows the solution to its novel problems yet. It potentially means nobody wants to touch it in a few years once the largest problems have revealed themselves en masse. If something has hype it's w

You can do the same in TypeScript with newtype-ts. I'd recommend it for the same reasons you'd use them in Haskell et al.

Does anyone know of some public repositories which are good examples of good commit hygiene as described?
