Yes, people absolutely cared about bits and bytes, because they weren't very many of them. (Programmers weren't necessarily thinking of them as monetarily expensive, because even today you don't just go slamming more RAM in to your machine if you need more. The problem is that there were only so many of them.) You could still see the residual hacker attitudes even five years ago, though I'd have to call it mostly dead now. But they were absolutely counting bits and bytes all the time, by default, in a way few programmers nowadays can appreciate. It's why we have "creat" instead of "create", it's why file permissions are tightly packed into three octal digits (as one of the old systems Unix ran on was actually a fan of 36-bit machine words, so 9 bits divided things more evenly at the time). It's why C strings are null-terminated, instead of the more sensible in every way length-delimited, except that length delimited strings require one extra byte if you want to support the size range between 256-65535. Yes, the programmers of that time would rather have one extra byte per string than a safe string library. Pre-OSX Mac programmers can tell you all about dealing with one-byte-length-delimited strings and how often they ended up with things truncated at 255 chars accidentally. In an era where "mainframes" shipped with dozens of kilobytes of RAM, yeah, they cared. |

Hmm, every software gig I've had in the past 5 years that's exactly what I've been expected to do because the extra ten bucks a month for a bigger VM is wayyy less expensive than engineering time. Interesting times.
