I had a Sinclair QL which pioneered the keyboard. It wasn’t great - it was far behind the Acorn BBCs and the Commodores) but it was quite usable.
There was significant vertical travel, and there was variation in the push the key gave back - increasing to a point of no return, then a quick downward movement to the thunk of the end of key travel.
I could type moderately fast on it.
I’m going to suggest food items that we still take from nature and eat with minimal preparation:
We have evidence of shellfish and fish being eaten for a very long time - at least the middle stone age at 140kya - in middens which are 10s of thousands of years old.
Honey is likely to have been a food source - a treat even - even before humans left Africa (so before 100kya) but sadly this would be invisible in the archeological record
I must not use jargon.
Jargon is the mind-killer.
Jargon is the little-death that brings total confusion. I will face the jargon. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the jargon has gone there will be clarity. Only sense will remain.
Surely that is reserved for QA!
It’s called a bollock dagger and, yes, it’s really phallic especially when holstered at your waist.
Exactly!
While the continents might look like they fit together, and the rock types and ages and fossils match at key points all down the coasts from Canada/Scotland all the way down to South America and South Africa, how on earth (sorry) would you explain how the continents are thousands of miles apart?
One theory posited the earth spinning so fast centrifugal forces ripped ehat would become the moon out of the Pacific, sucking Eurasia and America into the void.
That’s a Randall Monroe WhatIf if ever I saw one. Think of the energy involved! All life on earth would be extinct.
So these theories were laughed out of scientific court. Until Vine and Matthew’s seminal paper on magnetic stripes being mirrored over the mid ocean ridge showed there had to be something forcing the plates apart.
And to add to that, all the characteristics listed their green flags - characteristics used to judge people.
Maths and reality are different. Very different. Reality can be explored empirically while maths is logic not empirical. We can never say we are 100% sure about the rules/laws we have discovered about our reality, but we can say for sure that a maths theorem is true or false.
Maths is a set of self-consistent tools that can be used to predict what happens in reality. The mathematical description of reality is an estimate, contains countless assumptions and inaccuracies about where things are and what properties they have. In fact in quantum physics, we literally can’t know momentum and location at the same time.
Maths can describe (or I should say, approximate) realities that don’t exist.
Because maths and reality are different domains, we can know different things about them using different approaches.

All junior devs should read OCs comment and really think about this.
The issue is whether
is_number()is performing a semantic language matter or checking whether the text input can be converted by the program to a number type.The former case - the semantic language test - is useful for chat based interactions, analysis of text (and ancient text - I love the cuneiform btw) and similar. In this mode, some applications don’t even have to be able to convert the text into eg binary (a ‘gazillion’ of something is quantifying it, but vaguely)
The latter case (validating input) is useful where the input is controlled and users are supposed to enter numbers using a limited part of a standard keyboard. Clay tablets and triangular sticks are strictly excluded from this interface.
Another example might be
is_address(). Which of these are addresses? ‘10 Downing Street, London’, ‘193.168.1.1’, ‘Gettysberg’, ‘Sir/Madam’.To me this highlights that code is a lot less reusable between different projects/apps than it at first appears.
