As the Digital equivalent of the dilemma of the chicken and the egg. Which came first? Okay. Alright. And I was as confused as that. The reason its called bootstrapping Is that it comes from an old tale of literally pulling yourself up by your boot straps. So that way in which you would actually get something started is that you would pull yourself up with your bootstraps. and that bootstrapping sequence is the thing that starts that process. One of the hardest bits of doing Computing is that you ultimately have to recognise, that there comes a moment when you can’t understand it all. You can’t understand the thing that you are building is so complex that it doesn’t all fit in your head. Okay? Thats the hardest and most difficult moment I face I’ve ever faced. And it’s the bit that everybody kind of doing Computing, Struggles with. It happened to me when I learn’t about Compilers. Now Compilers are the things which take the programming languages that we have and translate that programming language, into the sequence of instructions that run, at the chip, on that computer. Okay? So they go all the way from a high level programming language like Java down to the machine codes that you might be running on. Here’s what it kind of gets difficult on this one. You’re gonna have to bear with me on this one. And as the digital equivalent of the dilemma of the chicken and the egg. Which came first? Okay All right And as I was confuse in that. Okay. And so you will write something in a language, say for example, You write something in one of the language, let it be java And you write things in java And it has a particular style of writting “if”, you know, if statements a whole set of things but how do you start? where do the first language come from? and how do you get there it is that moment of complexity that almost feels like magic ok, because it works And it teach you where to figure why it works And it feels quite allusive Bootstraping is is a means by wich we can allow our software systems to exist independent of the machines that they’re running on. Without things like bootstrap and without compilers You’d essentially have to rewrite programs and replicate all the instructions for every machine that you’d ever built; Ok, or every family of machines. so if you, if everything stayed at the level of ones and zeros and flicking switches you’d have to have a different sequence of flicking switches for every machine that exists in the world and that gets tiresome at best but virtually impossible given the complexity and the size we’ve got.
