Compiler Design

When we talk about women in the software industry our mind goes directly to Ada Lovelace but there is other (and in my opinion more important) woman that also it is necessary to know. I am talking about Grace Murray Hopper. Grace Murray Hopper was an extraordinary woman that established the bases of the Cobol Language and the first woman that not only though that computers were more than monsters of calculus. Influenced by the ideas and philosophy of Babbage she developed the very first compiler, the A-0 compiler. At first this compiler was underestimated by the community in order to change this point of view, Hopper tell the community to come and try the compiler with any problem that they had. One of the problems that the compiler solved was one on derivates, the machine accomplished the correct calculation of the first 15 derivates of a problem that a person was having of a very ugly function. Another thing that this compiler could accomplish, was the translation of French and

The very first thing that the podcaster said it is that the real name for GCC is Gnu Compiler Collection, it is important to know this because at the end it is the jargon of Computer Science and general culture among the computer scientific. So, let's start. First of all, we need to remember all the stages when we want to build a compiler in order to know how GCC internally works. So, the first thing that we will cover in this blog entry it is the lexical analysis; in this stage the compiler will strip down all the characters or character stream into a token stream this is, that the compiler will check if that tokens are reserved words or are variables that will be token in that program. In order to keep the second phase simple enough in this phase you create the abstract syntax tree (this is how we need to create the tree in order to produce or compute the operations in the order they are provided). In the third phase, like the podcaster said, the compiler needs to check

If you ask me today how will the hundred year language will be I will answer you I do not care about that because I think that programming languages will always need to be written by humans and not by machines (unless we want a dystopia like Matrix). Nevertheless, I found interesting the point of view of the author where he describes that the new upcoming languages will not be fully optimized, actually they will be the opposite because it will be hardware robust enough to run that kind of programs in little times. In my opinion I think that the new upcoming languages will have this feature the author mentions, coupled with this that language will be easy to write and learn it because the human being (I am including me) is lazy enough that we will learn and use that language where we do not need to stay ours and ours programming in it, we will use the easier languages to program. If we go back in time a few years I am certain that the programmers on that time would not use the
