What the heck is the CLR

I guess this reading did not surprised me because Microsoft has been working with the open source community and trying to push their development tools for quite some time.  I found very interesting the advantages of portability and compactness, mainly because we live in the age of downloads and compactness is a very important factor. Also,  as I would like to know more about security the part of implementing security in the multiple platform execution environment.  Lastly, the flexibility with the construction of typesafe meta programming sounded really good.
Specifically, the CLI works  using multiple concurrent threads of control which are basically a silly linked list of stack frames. It contains the following components: Instruction Pointer to point to the next CLI instruction, evaluation stack containing intermiediate values of computation, array of local variables, array of incoming arguments,  method info handle that contains information about each method, memory pool for dynamic allocation, return state handle to restore the method state, security descriptor. It has a lot more components than the JVM which makes it more secure.
It also contains Assemblies which are the modules containing the intermediate code and metadata for security, versioning, type resolution and processes. This manifest can include reference types like classes, interfaces, arrays and delegates, also structs and enums.
As a conclusion the CLI is a very complex and complete execution environment, it contains a lot of the elements in the JVM plus some others to support multiple languages instead of only C#. It is also a thing about C# having more features than Java.

How will programming language be in 100 years?

The reading was interesting, I think I've never thought that maybe the programming language I like the most could disappear. But it is true that the most inefficient way of coding is doing extra work, thus precise programming languages may be a better choice (for example Python or Clojure) but there is the challenge of real time apps and the slowness of these languages. At the end, simplicity makes it difficult to write an algorithm or at least normal algorithms. C is one of the most important programming languages, but it is very difficult to use because you can choose on how to do everything, even memory allocation. Which could be a very important tool for certain algorithms, other Programming Languages that are not that customized are faster to learn and faster to code but a little slower to execute. I think, by now, a language like C will always exist because we need this level of customization, but it won't be a success, it will only be used in special cases or for reusin

Women's greatest contribution to Computing

According to both, the documentary "The Queen of Code" and the reading "Grace Hopper - The Mother of Cobol" it was a woman the one who had the idea of creating a non-hardware specific Programming Language. It was such a contribution she was named Computing Man of the year, which she did not bother about the man. I think it is amazing for her time to gain the respect of all man in the area. I also think it is a shame that we usually do not hear this story, because we do not talk about computing history, it is very important and most of all encouraging to know that women in computing make big contributions. It is a shame that after a women invented Cobol, we only talk about important man in the area, our career is full of men, and there are no women encouraging programs to bring more of them into the field, even when they were the ones making the biggest contributions. It is true that today we have more opportunities for women, but at least in my school there is no
