Programmer Humor

We need to be able to express 0 and 1 as integers so that functionality is just being overloaded to express another concept.

Wait until the person who made this meme finds out about how many bits are being wasted on modern CPU architectures. 7 is the minimum possible wasted bits but it would be 31 on every modern computer (even 64b machines since they default to 32b ints).

This guy never coded in KEIL C on an 8051 architecture. They actually use bit addressable RAM for booleans. And if you set the compiler to pass function parameters in registers, it uses the carry flag for the first bit or bool type parameter.

3GPP has an interesting way of serialising bools on the wire with ASN.1

NULL OPTIONAL

meaning only the type would be stored if true, otherwise it won't be set at all

Wait till you realise the size of SSD sectors

I swore I read that mysql dbs will store multiple bools in a row as bit maps in one byte. I can't prove it though

pragma(pack) {

int a:1, b:1, ... h:1;

}

IIRC.

...or you can be coding assembler - it's all just bits to me

7 Shades of Truth

Redundancy is nice in the event of bitflip errors

I mean is it really a waste? What's minimum amount of bits most CPUs read in one cycle.

Pl/1 did it right:

Dcl 1 mybools, 3 bool1 bit(1) unaligned, 3 bool2 bit(1) unaligned, … 3 bool8 bit(1) unaligned;

All eight bools are in the same byte.

Does anybody ever figure in parity when comparing bit sizes and all that jazz or are we only ever concerned with storage space?

Now store the numbers (array):

0 0 0 1 0 1 1 2

think 8 bytes???
