dilI got dragged into a conversation today where a group of people collectively decided that binary, octal, and hexadecimal number systems are useless and stupid.
Most of them use hexadecimal every day. In their graphic design work. #FF5733 is not decimal. It is HEXADECIMAL.
Their argument against binary was that counting in it is inefficient. That 1, 10, 11, 100, 101 is dumb compared to 1, 2, 3, 4, 5.
These fools fail to understand that both systems are one and the same!
Every positional number system works identically. You have N symbols. You count through them. When you exhaust them, you reset and carry. Decimal has 10 symbols (0-9). Binary has 2 (0-1). Octal has 8 (0-7). Hexadecimal has 16 (0-F). Same mechanism. Different base.
Binary is not inefficient. It maps to transistor states. Octal compresses binary into groups of three-- which is why Unix permissions are written as 000 - 777. Hexadecimal compresses binary into groups of four --which is why every memory address and colour code is in hex. These are not alternatives to decimal. They are the same information at different compression levels.
The people arguing loudest had encountered these systems, used them regularly, and left without a single question about how any of it works.
I do not know what is worse -- the ignorance or the confidence it travels at.

David JONESThe ZX81 character set is objectively the best because A to Z immediately follow on from 0 to 9. 0 has code 28; A has code 38 (unlike ASCII where there is a gap of 7 codes: 0 has code 0x30, A has code 0x41). This means that to convert from 0 to 15 to a single hex digit, we can do CHR$(28+H), where H is the digit we are converting. If we need the most significant digit of a two-digit hexadecimal number we can do CHR$(28+INT(H/16)). But. Because CHR$ rounds its input, we can remove the INT: CHR$(28+H/16). But. Mysteriously INT is mathematical floor, whereas CHR$ rounds to nearest (and 0.5 goes up). So CHR$(28+H/16) is wrong when the least sig digit is 8 to F. But can be corrected with: CHR$(27.5+H/16). Haha.

StefanoGaivotaFiguring out a model for a stochastically flat D16 / hexadecimal dice.
This is a truncated sphere with face positions determined by minimum energy surface-confined electrostatic repulsion calculation iterated until zero calculable difference occured in point positions.
All faces are circles of equal diameter.
It does means that there is no definite uppermost face when one face is on the deck. So... each numeral has a decimal point which is positioned to be uppermost when its opposite number is down against the table.
Still need to adjust numeral emboss depth for equal volume removed but that's down in the weeds with regard to fairness.
