Operating Systems Week 1

     This week was a bit rough as there was a lot of detailed information needing to be grasped. Though with that being said, I was able to learn a lot. I've spent a lot of time this week getting more familiar with the C language. I learned more about how to use addresses and pointers, characters arrays, and memory allocation with the "malloc" function. Additionally, I've learned how to use the GDB command line tool to debug my code by setting breakpoints and stepping through it. 

    Apart from C, I was also introduced to operating systems and system architecture this week through readings and lectures. I learned about layers of functionality which have user and kernel modes, separating access to hardware. With that I learned about the TRAP instruction, allowing the user mode process to call functions from within the operating system's memory. In addition to these readings and lectures, I had a discussion with my classmates about file permissions and their importance for privacy and security on a system. I look forward to learning about processes next week.

Software Engineering Week 4

    The most interesting thing I have learned about in my reading of "Software Engineering at Google" are how each of the various processes are executed. While I am familiar with most of the processes I've read about so far, including code reviews, unit testing and system testing, the manners in which these are executed at Google are different from how they have been executed in my professional experience. For code reviews in particular, Google engineers ensure they invite various other software engineers to fill the roles of correctness and comprehension checking, language readability checking, and code owner. However, in my experiences this is not explicitly required. While a single engineer on the team often fills a couple of these roles, there wasn't an engineer specifically dedicated to carry out each of these tasks. Another interesting thing I learned was a recommendation about the use of the "sleep()" function in testing. While sometimes waiting is re...

Capstone Project Week 10

   What did you accomplish this week? This week I looked into integrating the stac-browser container within the docker compose YAML file provided in the stac-fastapi-pgstac project. In addition I cleaned up some unnecessary data included in STAC items written by our parser as well as read further documentation from the National Hurricane Center on how I can do additional parsing on dropsonde remark messages. I also published a build and tested docker image including our team's parsing tools to docker hub to allow it to be pulled from our AWS instance. What is your plan for next week? Next week I will work with my team to get our STAC Server running and hosted within an AWS server for demonstration and testing with our stakeholders.  What challenges, if any, are you currently facing in project development? Do you need instructor assistance?  So far local development has been smooth on a Windows 11 operating system. Containers are able to be built and ran using docker...

Capstone Project Week 11

What did you accomplish this week? This week I pushed updates to our parser development branch which included additional parsing for remarks and removal of certain metadata properties that were unnecessary for describing the who, what, when, and where of a dropsonde message. In addition I was able to get our parser, STAC API, and STAC browser containers running and hosted AWS, load our STAC database with STAC items using our custom API endpoint integrated with our parser, and test our application's availability on the internet. After confirming our application's accessibility, I scheduled a demonstration with our mentor to show our progress and attain feedback. What is your plan for next week? Next week I will demonstrate our STAC parsing and catalog browsing capabilities within our container hosted on AWS to our project mentor.   What challenges, if any, are you currently facing in project development? Do you need instructor assistance?  I'm not facing any challenges at...
