Likewise, TIL. In your link however it states "Example 1: Numerical Context Let's consider two real numbers, a and b. If a is neither greater than nor less than b, but they aren't explicitly equal, the relationship is ≹" How can that be possible?

That doesn't seem possible with the reals. An example from programming that comes to mind is NaN ≹ NaN (in some languages).

The floating point specification mandates that nan does not compare to nan in any way, so it should be all languages. If you want to know nam, use isnan()

Think how any number on the z axis of complex plain isn't equal to the a number of same magnitude, on x and y axis. Now if you really think about, a number of a given magnitude on x axis also isn't exactly "equal" to a name of same magnitude on y axis or vice versa. Other wise, -5 and 5 should be equal, because they're the same magnitude from 0.

But |5|=|-5| so I don't exactly see your point.

Edit: oh, I see what you mean. 1 is not larger or smaller than i, but it also doesn't equal i.

This doesn't really pass the small test for me either, but to play devils advocate: Imagine you have 2 irrational numbers, and for some a priori reason you know they cannot be equal. You write a computer program to calculate them to arbitrary precision, but no matter how many digits you generate they are identical to that approximation. You know that there must be some point at which they diverge, with one being larg…

Maybe you will find the proof that the infinite series 0.9999... exactly equals 1 interesting: https://en.wikipedia.org/wiki/0.999 ...

Wow, can't believe I've never realised this. How counterintuitive.

The 1/3 * 3 argument, I found the most intuitive.

for the Reals, it is only hypothetical, the domain has a total order. \inf and $\inf + 1$ comes to mind but I don't think it really counts

> \inf and $\inf + 1$ comes to mind but I don't think it really counts

That just depends on the numeric structure you're working with. In the extended reals, +inf is equal to +inf + 1.

In a structure with more infinite values than that, it would generally be less. But they wouldn't be incomparable; nothing says "comparable values" quite like the pair "x" and "x + 1".

My gripe with most programmers that they keep re-learning the same narrow set of skills while ignore the rest that actually makes someone a efficient expert.

I think learning some narrow skills is fine but the real issue comes when you don't deploy code to production. Because Production is the best place to learn actual problems.

It's a flawed psychological argument though, because it hinges on accepting that 0.333...=1/3, for which the proof is the same as for 0.999...=1. People have less of a problem with 1/3 so they gloss over this - for some reason, nobody ever says "but there is always a ...3 missing to 1/3" or something.

That would be nice, but people keep hiring based upon specific programming languages and other programming specific skills.

You usually don't want work companies that do resume matching.

This article has opened up a new perspective for me. It articulates very well that software is a means to an end. It's a craft that can be used to solve a problem. In my past I often emphasized the craft part too much. As if only writing perfect code is all you need to do in order to be successful. The really important stuff is understanding the problem you want to solve and being sure that software is the tool to so…

The person understanding the problem to solve and the person crafting the solution don't necessarily need to be the same person, though.

They can, in fact, be two people with completely different skill sets and if one of them ("you") can "only" write perfectly beautiful code, they can still succeed by relying on the other for breaking down the particular problem.

If we ditch the business part what's your recommendation to pay rent?

Just ditch the paying rent part.
