Ruby and the Interpreter Pattern

 This article was very interesting, specially after the programming languages course, first of all,  the S-expression Interpreter Framework (SIF) is presented as a tool for teaching Language design and implementation. As mentioned at the end of the text, this is taught in the last four weeks of the programming languages ​​course, of course, this fact makes thing a lot more understandable, and after reading it I felt very grateful for having the opportunity to at least understand the way things work.

This framework is written in Ruby, which makes thing more interesting since it is a very flexible language and allow many possibilities. 

One of the most interesting facts of the framework is the idea of being so flexible that it can be extended to satisfy almost any need, functional languages, imperative programming, etc. Almost anything can be achieved by this and by extending the framework, this of course creates a very versatile environment.

And also something interesting to me is the fact that Ruby is very similar to Python, and to be honest I do love Python, which makes Ruby a very strong option for me and creates a lot of interest

Even though the pattern is a short version of the compiler, it can really help to understand the way a compiler works and why it works that way, I will be taking Software Design and Architecture next semester, but I would have really liked to take it before compiler design so that I could try to better understand the fundamentals behind the project, or at least make it easier.

Making Compiler Design Relevant for Students who will (Most Likely) Never Design a Compiler

 This particular article changed my compiler perspective in a real ideal way (the perspective not only of the subject but of a compiler in general), I never really fully understand the main purpose of the subject, and the fact that it is considered the hardest one (in terms of programming) and it has changed my perspective due to the fact that it shows how we probably would never need to actually create or develop a new compiler (or compiler in general), but instead the course show us how to manage certain deep level problems that would remain hidden otherwise. In general, the course is designed to help us analyze and structure common problems that we might have to face in the future. The thing that really caught my attention is the abstraction way to see the things and how that could help us to solve problems, the idea behind this statement is to always try to see the problem as abstract as possible, and that could help us to understand the problem on a simpler and modular way which i

Mother of Compilers

  Women in technology has always been a very complicated topic, it is typical to see women outstand in many fields, but for some reason, their interest in technology related fields seems to be non existent, this is why this subject has been so interesting, I believe the fact that many complex cases have been solved by women is very interesting, and left me questioning how much better it could be if more women start selecting IT related careers. In the last decades, most of the news reflected only the part of the work that involve men, this left an stereotype that states that only men can achieve success in a technological career, which is entirely not true, the problem is, the stereotype has already done serious damage and this reflects directly in the amount of women studying IT or engineering related careers, although, nowadays there has been a lot of efforts to try and eliminate this stereotype and have more women to select this type of careers. I found Grace Hopper as a true inspir
