streets of rage 2!

This was a cool talk on teaching programming gradually (with a lang called hedy) at last year’s strangeloop: https://youtu.be/fmF7HpU_-9k - might be some useful takeaways for you in there

It was pointed out to me i should add OOP. Burn it all down!

Indeed, the problem with gui apps is when you can’t script them!

I always loved alfred on osx, then loved scripting rofi on linux, only to come back to osx years later and find alfred can’t be invoked with stdin options. It’s damn shame….

We used to call this ‘Code is Cheap’ at my last job - you’re spot on about the value of it

I think you’re right re:oop - let’s throw that in there too.

One problem is naming things - bad names/naming conventions can start things off in a bad direction, so you spend forever figuring one out… but do you really need this thing you’re naming after all?

Maybe the hot-take is more like: All code is bad, so less code is better…. what should we drop first?

Sorry, I liked this hot-take setup and I’m shooting from the hip a bit. Maybe i actually mean objects/classes, not types? Can’t everything just be a bag of key-values, like in clojure?

I have been building mostly prototypes (games and wm-tools) for a year, so most of my context is getting things working to see if they are useful rather than locking them down.

I thought about my argument a bunch, and while i have alot of complaints, it all sounds like non-specific whining to me, so i’ve decided to give up.

types and unit-tests have their place. Fine! I admit it! i was pushing a hot-take I’ve had on a few occasions, and I’m glad to see this programming community is alive and well! If you need me I’ll be in my clojure repl.

Fair! Naming is hard, but maybe that’s no excuse for not defining a thing

I suppose i should at least caveat by saying i don’t by any means advocate for all dynamic langs over statically typed, and i agree types/unit tests are necessary for most languages. So please don’t make me write python over rust!

You can get the benefits of types/unit-tests via static analysis on a per-function basis with clojure and a library like malli, and for me that hits a minimalist sweet-spot.

Sounds like a frustrating issue - feels like salesforce shouldn’t be enforcing that number vs string in the first place, because it could just get coerced later on. But, it’s out of your hands for sure, and there are tradeoffs for them making their API “easier” to work with.

And yeah I’m being a bit obstinate in this hot take - it’s easy to get away without types when working on smaller projects and in more modern languages, especially for low-stakes dev tooling. In larger projects, types can help improve confidence during large refactors.

I just want less code to maintain in general…

Very happy to share this hot-take :) Definitely code-base and team-size are a huge factor, and I mostly work on my own projects, so each project is very different. still, I expect to get downvoted into oblivion by the last decade’s influx of typey-langs and -devs.

I think most love for types is folks being happy they don’t need to assert on the input to every function, i.e. static analysis and reduced unit-tests. It’s hard for me to not see types as asking folks to pre-design their entire system (by defining types first!), before you’ve even started writing a few functions, which are actually what the system should codify (behaviors, integration tests). It’s also frustrating b/c types don’t guarantee that the system does-the-thing, only that the type-system and compiler are happy, so it’s like pleasing the wrong boss, or some metaphor like that.

I like to work with behavior directly in functions, which should be the same regardless of the type passed in. Unfortunately most dynamic languages have their flaws (js,python,etc), so this kind of opinion suffers b/c of those languages… similar to type-favoring opinions suffering b/c of langs like typescript.

Nil-punning makes me very happy - that’s a hill I will actually die on. Almost every project i’ve worked on, there’s no reason to go out of the way to specifically handle every case of not the right input or oh-no-it’s-null! Whenever you have null, you just return null from this function too, and guess what, everything’s fine - no need to crash and blow up b/c one thing wasn’t there. Mostly this is a complaint about things completely crashing for no reason, rather than being incomplete (i.e. some data missing) but still working for the user.

Anyway, lots of different use-cases, and use the right tool for the job, etc etc. types and unit tests are useful for some things.

100%! It was mind-blowing to realize lisps are actually syntactically simpler than all the non-lisps so popular today

Takes a bit of love from editor standpoint unfortunately, so most devs will just never attempt that hurdle

Types and unit tests are bloat that increase the maintenance cost of whatever code they are involved in. Most types force premature design/optimization. Most unit tests lock up some specific implementation (increasing cost of inevitable refactors) rather than prevent actual bugs.

Nil-punning in clojure has spoiled me rotten, and now every other language is annoyingly verbose and pedantic.

Just to share a perspective from erlang/elixir: pattern matching to filter for only happy-path inputs and the principle of “letting it fail” (when the inputs don’t match the expected shape) works really well in some paradigms (in this case, the actor model + OTP, erlang’s 9 9s of uptime, etc). In that kind of architecture you can really only care about the happy path, because the rest is malformed and can be thrown away without issue.
