This weekly review is the first one that I’m typing from my home office in our new Renton house. And being in this new house feels good, feels great. I feel extremely blessed and luckily. And although I do know that Jess and I and Elliott and the dogs could live contently even if the…

For project 2 of my advanced operating systems course, I quickly typed up what I thought was a functional simple centralized counting barrier implementation. However, after launching the compiled executable multiple times in a row, I noticed the program would hang and not immediately exit … damn deadlock. Instead of loading the debugger and inspecting…

The main take away with the introduction to distributed systems lectures is that as system designers, we need to carefully inspect our program and identify what events in our system can run concurrently (as well as what cannot run concurrency or must be serialized). To this end, we need to identify what events must happen…

I’m implementating the dissemination barrier (above) in C for my advanced OS course and I’m not quite sure I understand the pseudo code itself. In particular, I don’t get the point of the parity flag …. what’s the point of it? What problem does it solve? Isn’t the localsense variable sufficient to detect whether or…

My body aches from the first day of moving houses, my body sore from all the loading and unloading of tightly packed boxes from the house and into the back of the 15″ foot U-Haul truck. Rant U-Haul at Burien employes some of the most unprofessional staff with the worst customer service. The staff were…

I want to learn how to better market myself and what it means to create my own personal brand and how I might be able to apply these marketing skills in my career (as a software developer and computer scientist) and as a writer. Because I do wonder what sort of impact and influence I…

Yesterday … was exhausting. A few times throughout the day I actually felt my body shut down and I nearly fell asleep while working. Although I cumulatively got like 7.5 hours of sleep, my sleep was constantly interrupted since Elliott has been (presumably) teething and letting out these screams at 1:00 AM and 3:00AM and…

I’m watching the YouTube learning series called “Introduction to OpenMP” in order to get a better understanding of how I can use the framework for my second project in advanced operating systems. You might find the below notes useful if you don’t want to sit through the entire video series. Introduction to OpenMP: 02 part…

Questions I thought about during the day How did society overcome the Spanish Flu and how did the people during that time return back to normal? I doubt some vaccination ended the pandemic… so how did we all get over it? And how will it be the same (or different) this time around with COVID-19…

The purpose of this post is to take a snapshot of my understanding before I begin working on project 2: implementing (two) synchronization barriers. Although I picked up some theoretical knowledge from both this course (i.e. advanced operating systems) and GIOS (i.e. graduate introduction to operating systems) on barrier synchronization, I actually never implemented barriers…
