Have you ever wondered what really goes on when your computer takes a higher-level language, like Javascript or C, and turns it into something it can read? Quine8 (Q8) is a simple virtual machine that takes the most basic building block a computer can operate on, bytecode and runs it at a fraction of the speed of a real CPU, allowing you to watch it run each step of the way.

Can anyone remember when the times were not hard, and money not scarce?

No.
I disassembled an executable just yesterday to make sure the compiler had optimized my code in the way I wanted.
Low level machine code is not magical. You should read it sometime, to see exactly what the CPU is being instructed to do.

this. I rarely write assembler, but in science getting the absolute best performance is often required...
I worked on some GCC/GPU stuff last year, where getting the assembler proved to be important for the diagnosing the (incorrect) maths!

i have, because I got sick of their shit tracking me. they were reading more about me and required stuff to set tracking cookies before I even agreed to a eula. or when their privacy policies say 'we do not honor do not track' stuff because its too hard, and yet have 30 different javascripts running? I didn't need javascript to state my do not track preferences, and yet I have to rely on disabling java script to enforce it.
Now I review all of that, because I don't want my browser or computer running what I didn't indend for it to-- or I don't permit it at all. thank you noscript! So many sites run faster now!
