Had a similar experience lately where we had a team fresh off a rails project get up to speed on Scala and complete essentially double the work we thought they'd get done. That being said it was much more complex than basic CRUD

Have you ever honestly worked on a system that logged the results of every query run?
183.
by hderms 8y ago
Not to be a naysayer but it might be a better effort to prevent having to do a bunch of work before returning a response. Have you considered polling for all the jobs to be completed instead?
184.
by hderms 8y ago
It's clearly worked for you because you are using what I would consider very idiomatic phrases. Good job, this is obviously not easy to do.

I think it's pretty common complaint to say Chinese doesn't translate simply to English. Like Chinese poems are said to contain wordplay based on alternate pronunciations or homophonic information which simply can't be transl

Agreed except product types aren't the same as sum types, product types are records or what have you

I think there are compelling business reasons to use Scala and hope Scala 3 simplifies the language like it promised. I don't personally think modern Scala isnt super hard to understand but there are some unpleasant edges to the langua

I think implicits are fine as long as they're used primarily for the typeclass pattern. The extension methods and conversions aspect of implicits should be confined to library DSLs

The handler being a typeclass in Haskell vs the enumerated cases being pattern matching?

How do you reconcile the fact you say type systems aren't useful but also that data schemas are useful. SQL is a typed language and it would probably be insane if it wasn't

I mean if their goal is to get Elixir developers interested then I think that it satisfies.

Maybe is perhaps suitable for things that can go wrong in only one specific way, but how many of those are there? Agreed that Either is preferable

What's convoluted about it? Exceptions jumping up multiple stacks and being rescued or reraised or what have you is convoluted. If you mean errors as return values then I agree, monads are more complicated than returning a simple error

am I understanding that you are suggesting code that explicitly avoids 'do' notation in Haskell can be more imperative than code using 'do' notation? I don't get it

I am leaving the ruby ecosystem primarily because dynamic typing doesn't jive with me and the ruby import system is lackluster.

What alternatives are there to what Scala provides? What newer language would a 'sane' person advocate?

How many problems out there are really apropriately solved by runtime metaprogramming?
198.
by hderms 8y ago
In practice the difference in guarantees between a static type checking system and a runtime one are so vast that I think they're mostly incomparable. Runtime checking is like doing most of the work of modelling a program with static t

Yeah, that is important to recognize, but floating point numbers could obviously sample continuous measurements with less loss than integers.
200.
by hderms 8y ago
Yeah but I think it's important to consider whether any microservice should be able to listen to any other microservice inserts or updates. I think using the replication log as the underlying mechanism is a good idea, but you should re

by hderms 8y ago
That was the conclusion I came to as well. If you just want to push data to a data warehouse by listening to the WAL or NOTIFY and then batch a bunch of updates together that's one thing. If you intend it to be application level events

It's a reasonable point but perhaps a bit outdated? Containers more or less allow interpreted languages to be "statically linked". In the past you had to care more about whether system X had library Y installed but that seems

Yeah, my girlfriend and I agree. Hogfather had the best translation of the three Sky productions. The cast was great and it managed to hit the right tone the entire time.

I personally feel like there's still room to build something that's more terse, yet equally as powerful as SQL. get name, age -> (foos.id X bars.foo_id) |> get first(name) |> head as opposed to select name from (select fo

Very thoughtful and educated response. I couldn't have envisioned a better answer when I decided to ask that question.

by hderms 9y ago
What exactly would be an alternative to call/return? I've seen that term thrown around before but I don't know how to Google for it effectively. Is it an alternative to other execution models like fork-join or something?

by hderms 9y ago
I agree in the sense that your system will be the most flexible provided you use composeable and easy to understand code as much as possible. Overengineering is overengineering because it trades complexity for "flexibility" but th

Fantastic article. This is the kind of stuff I go to Hacker News to read. Had never even heard of half of these conceptual leaps.

Compile time might be the only thing I truly dislike about scala.
