That is more than I have spend on computing hardware in my entire life...

>The ancients may have understood negative numbers, but IIRC the concept of zero (additive identity) wasn't understood until Arabic Numbers / Algebra. So "zero" isn't real, at least not to the Romans or Greeks. T

I think you are missing the point. Kronecker does not deny that irrational numbers exist, he states his belief that the fundamental number system which is inherent to reality are the natural numbers. That (by divine authority) are the irr

Crypto currencies solve a legitimately interesting problem, which makes it a fascinating technology. My professor called it the "nuclear science" of computer science. What is striking to me is that most people do not even understa

Excel is much worse than most other programming environments. It inherently hides context, the flow of data and how code relates to one another. It makes it extremely difficult to create software where you can follow the flow of data, mores

Excel and spreadsheet software in general is great for certain things. It just scales horribly, it is inherently opaque and naturally hides the relations between its parts. People actually use it as a general programming language, which le

For me a lot of these new "learning concepts" seem like justifications for teachers to make their job easier, at the cost of actual educational results. Structuring a classroom is no doubt hard and exhausting work, so is teaching

I really like using the terminal and I even really like TUI applications. But still, I can not believe this is a good idea. Every TUI is an enormous hack, legacy piled on top of legacy, trying to twist a simple terminal into a general purpo

I had an interview offer from a company doing facial identification software. After some deliberation I (politely) declined. I really think much of the current AI technology shouldn't exist. I am under no illusion, it will be develop

Germany has tried to move away ftom nuclear and fossil fuels at the same time. Germany currently has the highest energy prices in the world. Whatever you think about green energy in the past, one thing has to be certain. It did not work. Wh

It is slow and doesn't really solve the problem. Representing the numbers in base 10 does not make it any clearer whether the numbers are equal.

This is not the issue. Floating point numbers have problems when A and B differ greatly in magnitude, then A-B might easily be equal to A and so ((A-B)-A) LARGENUMBER can still be equal to zero, even if B was e.g. 1. This is not a problem w

You are absolutely right. So many times I have seen people complain about this or that "flaw" in floating point arithmetic and proposing this or that alternative system. It always makes me question whether they have actually tried

This is a complete fallacy. Just because output and input accuracy are low, that does not imply that intermediate accuracy can be low too. You gave the example of a milling machine, of course in most cases you wouldn't expect it to be
