That's a lot of words, but how is that even possible?

Pointers and arrays are basically interchangeable in C, and you have to do that constantly in any large program. Even the blog post has a malloc in it.

Once you start passing around a pointer to the middle of the array all size info is lost.

Are you talking about -fsanitize=address? It's too slow to be used in production

It doesn't depend on the application unless the application shares the same pointers between x86 and arm which doesn't make any sense to me.

Otherwise they're right, it's not the intersection that matters but just the total bits available

Fusion360 doesn't work on Linux. Or at least I tried multiple times and couldn't get it to work

Maybe a generous interpretation of the comment and a realisation that common language isn't always 100% precise would be better than pointless arguments about semantics.

There is only a single printf written in the source code.

Do you have a source on that?

Source?

A source. I need a source.

Sorry, I mean I need a source that explicitly states your argument. This is just tangential to the discussion.

No, you can't make inferences and observations from the sources you've gathered. Any additional comments from you MUST be a subset of the information from the sources you've gathered.

You can't make normative statements from empirical evidence.

Do you have a degree in that field?

A college degree? In that field?

Then your arguments are invalid.

No, it doesn't matter how close those data points are correlated. Correlation does not equal causation.

Correlation does not equal causation.

CORRELATION. DOES. NOT. EQUAL. CAUSATION.

You still haven't provided me a valid source yet.

Nope, still haven't.

Average western person emits more co2 than the average Chinese person. Not sure why we would go after them unless you just don't like to see your 'team' look bad

Put some wd-40 on your bike's brakes and see if you think it's not a lubricant.

Maybe you think it's not a _good_ lubricant? But a lot of its use is to extract stuck things which requires a thin lubricant
