Why have a mutable class to represent temperature - a simple value class with two fields? Why not just construct a new Temperature? I mean if performance was an issue, you'd just use plain doubles instead, right? I'm open to the i

This is a bit abstract to me. I don't tend to write mutable classes. And if I do mutate fields, it's for a "reason" (and I'll name the method after that reason). If you feel like it, write out how you'd impleme

I get what you're saying, but at the same time I don't understand how you'd implement the class and why. class Temperature { public final double celcius, kelvins; Temperature(int celcius, int kelvins

Why not give your "setters" a real name that describes what they're doing? https://news.ycombinator.com/item?id=15606777 In the structs & records world (C, F#, Rust, etc) they never seem to have this iss

I appreciate you thinking of an example, but I guess I find it a bit convoluted. Couldn't you also refactor that by changing the constructor of your temperature class so it converts things to Kelvins, rather than converting it every ti

But by definition getters and setters lack lexibility. They expose the internal representation of an object. They stop really being "objects" - high level opaque things you send messages to - and they turn into big porous bags o

Yes, I am. It was a separate tangent, and a bit off-topic.

... To write such a class responsibly, one has to write a lot of low-value, repetitive code: constructors, accessors ... If you're writing a plain data class, why on earth would you write getters and setters? Just make your fields pu

I would, but I'm still waiting for the pin wheel to stop spinning... I miss the old C2.

I've often thought about an editor for a stack/concatenative language that makes the arity of words clearer. like when you select a word it highlights which of the previous words in the definition it's consuming. I don't

You're bang on the money: Tamsui is a romanisation of the hokkien name, not the mandarin one. There's a few other non-mando names floating around, like Taroko (an aboriginal language). I have a Taiwanese book for school children t

The different chinese languages don't seem to be dialects in any objective sense. I have no idea how it started being called that in english (bad translation of 語/話 maybe?), but Hokkien and Mandarin seem about as different from ea

"chinese" isn't one language. It's a set of many languages which share some grammar and a common logographic script I don't think that's true for any chinese languages other than mandarin and cantonese. I&#x2

It seems more likely to me that compulsory education conducted entirely in a "national language" is the culprit here. How many of these stories involve "we were beaten for talking in $LANGUAGE at school"?

If your role in a company is so removed from the business or stakeholders that you're being assigned tasks like "add 15 fields", then IMO you're already in trouble. That's part of a larger issue though, where we act

A lot of it comes down to the fact that this isn't engineering, and we aren't engineers.[0] The field has a very low barrier to entry (much lower than a bachelors degree). The standards are low, the expectations are low, and there
