wk4: The Illusion of Memory

 I remember during my intro to comp arch course at a community college, the professor always showed us and reminded us that the memory that the program sees is not the physical memory.  I appreciate  him teaching us about this early on as it gained my interest to learn how exactly the OS manages that.

Memory virtualization is a topic that makes every process think they have their own playground.  This allows the OS to manage the memory allocation while the program itself can do what it was programmed to do.  I also learned about paging which allows the translation of the virtual memory space to the physical memory locations.  

 For as long as I remember I tried again and again I tried to learn linux systems and something that caught my eye was the step to make swap space on the harddrive.  I wondered why Id have to do such a thing since windows doesnt have it.  But the idea behind it to use the harddrive as a backup memory location makes sense

CST 363 Wk7:

 I 100% prefer MongoDB, it's very intuitive compared to SQL statements, since it's more modern.   Some similarities are the CRUD operations, which makes going from SQL to MongoDB easy to handle. I do like how flexible the data is stored in MongoDB rather than SQL.

Week 4 Learning Journal

 Part One: Set Your Educational Goals I'd like to focus on developing an excellent portfolio of projects to show case my programming and creative problem solving skills.  How that goal is judged will depend if I can change my career from mechanical engineering to programming! Part Two: Set Your Career Goals I'd like to have a software oriented role, which can be in a variety of fields, but my main goals would be in flight/physics simulation modeling and/or thermal simulation modeling.  Either developing the models themselves or the software that engineers use to solve these types of issues. Part Three: In 18 months, I think I'd do really well, maybe in 70-80% percentile.  I'm genuinely interested in learning computer science topics so it will be a fun journey forward.  Part Four:  I finally caught up on all my coursework after falling behind in the first couple weeks, so I'm glad to have learned more content this week.  This week after working on my ou...

wk2: Trust the Process

 In the year 2012, Kobe Bryant was having a season filled with injuries and ups and downs, but confidently he said to "Trust the process" in order to achieve his goal of another NBA championship.  While he wasn't able to get this sixth championship, his saying still lives on.  Though I'm sure Kobe wasn't aware that trusting the process lies within our computers that allows them to perform whatever we tell them.   I've learned the interesting bits about how the OS manages processes through the fork() and exec() commands, which appear simple but allow the OS to perform multiple processes.  I later learned about how the OS manages permissions between the user and kernel, so the user can temporarily access higher permissions through the use of traps. Also fun to think about the potential of traps if one were to gain access, they can run malicious code.
