You're both right, but not all languages give you the choice. And a lot of types are implemented badly. For example as a subclass of a number class, so that `amountDollars + timeSeconds` and other nonsensical statements aren't errors.
I'm not optimistic on unit types myself. I've found that unit-named variables often with transparent type aliases as documentation (type Sample = usize, type Amplitude = i16/f32) have many of the advantages of distinct units, without their downsides compared to bare numbers. In several projects where I've used naming and transparent aliases comprehensively, I don't recall ever letting a unit mistake escape from my local tree into master, since I reread my own code when committing and merging. In one case (https://gitlab.com/exotracker/exotracker-cpp/-/blob/dev/src/... used to have two EXPLICIT_TYPEDEF) I did add distinct units because I found I was mixing together two types too often during development. Though I find that unit types come with significant disadvantages (ergonomic and semantic flaws), making them far from strictly better than bare numbers (much like Rust is far from strictly better than C/C++/Zig):
- You need an implicit conversion to eg. size_t, otherwise you can't pass (smp: Sample) into array indexing like (amplitudes[smp]) or data slicing, without an extra conversion or accessing the underlying value like (smp.v). But you can't allow (smp += midi_pitch) to convert both arguments to int, then cast the result to Sample when assigning.
- You need some conversion to allow (smp + 1) with type either integer (convertible to Sample) or Sample, unless you want to annotate all arithmetic with boilerplate like (smp + (Sample)1), or (smp.v + 1). I've experienced this problem in my own code, and had to write (smp.v) when my compiler saw (smp + 1) and told me it didn't know whether to wrap 1 or unwrap smp.
- Expressions of type Amplitude * 2 should have type Amplitude. Go's time library gets this wrong, where multiplying Duration * Duration = Duration, which makes sense if Duration is an integer like i32 or i64, but not if Duration is a unit system dimension.
- (not a regression but a limitation) Units won't stop you from adding two temperatures in Celsius. To fix this you need separate coordinate and displacement types, which is a new pile of complexity.
- You may want distinct types for "samples/sec" and "cycles/sec". Modeling this in type systems has multiple current approaches, all of which rely on language support (F#) or complex type machinery I've had issues with.
- You can't easily convert between slices of f32 (like an audio buffer provided by the OS), and slices of Amplitude<f32>. Or worse yet vectors of f32 and Amplitude<f32>. (This problem affects bulk data in collections, more than scalar types generally passed and returned in the stack.)

I have seen investment banks disable all logins for a whole division or trading floor, invite the people they aren’t firing to an all hands / town hall meeting to tell them as much, then announce to everyone else on the floor that they no longer have a job and will be escorted out of the building with any belongings they choose to collect within 30 minutes.
I’m not sure how normal it is, but it doesn’t objectively seem like there’s anything wrong with it.
Ooooh that is dark. Must have been fun for the smokers who have been around for a while. Having worked at a company that went through a few years of trouble, there were all sorts of little signals like that you'd learn to pick up on.
There's a scene in the movie "Margin Call" (about the 2007-2008 financial crisis) in which most of a floor of employees in an investment bank is laid off: https://www.youtube.com/watch?v=zn2Xf9hAFcE
A company I was familiar with in the 80's had a subsidiary in another state with a couple hundred employees. They decided to close that office, and lay everyone off.
Being nice guys, they gave the branch 3 months notice of the closure and layoffs, and expected them to keep working as usual.
After 3 months, the parent company officials arrived to find the office building empty and looted clean.
For me, the most important thing by far is to not have to extend my pinkies to another column. A good thumb cluster and mod-tap implementation dwarf any of what you listed for my needs.
I'm not American, but I doubt I would have gotten MS were it not for terrible diet, stress, lack of sleep, various deficiencies at the time of diagnosis but also during childhood. Also had a very bad bout of mononucleosis when I was 10 (while also being malnourished), so these things can go quite far. So I think my nervous and immune systems were always frail.
So sorry to hear. As of 2022 there is enough evidence for a causal link between EBV (the virus that also is behind mononucleosis) and MS later in life. The hope is that humanity will eventually have strong drugs and maybe a vaccine. Unfortunately, progress has been very slow until now. I hope things will move faster now that people could convincingly argue about this link between a virus and the disease.
> Can enter any building? Can I make a hole in the ground? Can I cut trees? Can I kiss NPCs? Can I demolish any building?
I'd really prefer for the developer to focus on the gameplay and plot rather than make a perfect simulation of earth. What you describe sounds like a cool sandbox, like Flight Simulator, but isn't appropriate for most games.
From my experience they learn from the older kids as soon as they start school. At least in my culture. My daughter came home saying "shit what the fuck" (in English, despite English not being the native tongue of the locality) one day. And now she will curse like a pirate when she hurts herself. But she already knows they are words that people attach special meaning to: she avoids them when "not needed", for example. Except when she wants a reaction, which she never gets from me at least.
We don't use many such strong words ourselves, but like with many things she learned on her own in the cultural melting pot that is public school.
Just my own observation, but all the kids I remember that cursed a lot weren't very good at English. Not sure if it is correlation or causation, but who needs to find the right word to express yourself, when "fuck" or "shit" almost certainly fit the bill?
Maybe people who curse poetically are even better at English than non-cursers, but that probably comes with age and isn't relevant to advice about children.
My anecdata is similar, but rather: the little kids I know who curse a lot and openly, have terrible manners overall. Talking nasty to grownups (and other kids), etc.
No it doesn't. It rewards people with the social skills to know when it's acceptable to use certain words that aren't acceptable in other contexts. But that's just a part of 'society rewards people with high levels of social skills'. If your experience has been that successful people (i.e., 'people who were rewarded by society') don't swear, then your experience has been very different from mine.
> Why use the same language as drunken sailors and criminals?
Aside from hate speech, I honestly don't care what kind of language my kid uses. But I'd be pretty disappointed if they reduced groups of people into negative stereotypes like this.
Indeed. Some sailors are amongst the greatest people I've met. And their language was salty.
Language is communication. Context is important. You don't bust into a church or interview swearing loudly. You don't try to communicate every thought with a curse word.
Maybe his point isn't that cursing is bad, but that you should set an example for proper manners. Like, the language they should use when talking with schoolteachers, at work, etc.
That's my household: they'll hear plenty of salt when we play Jay-Z or Run The Jewels around the house, and it's no big deal if they cuss while telling us about their day, but we'd never tell them to "Pick up the fucking dishes."
