Arlon's CSUMB Intro to Operating Systems CST-334 Module 8 Learning Journal #8/#32 for the week Wed 08/11-Tues 08/17 (Sat 8/14?), year 2021 Update Thursday 08/20/2021 - The school has officially notified me that these circumstances have been acknowledged, recorded, and presumably corrected as practicality permits, as well as considering actionability against observed offenders! Update Saturday - yeah - the final too - compromised - for that final, and for all the quizzes, and for the midterm, and also for the labs, cheaters literally could have literally simply drag-n-dropped the questions - to the chrome bar - to cheat - no typing necessary. I would never, ever, ever even consider anything like cheating and I am shocked and appalled. Update Friday 08/13/2021 Everyone should know, this class is entirely compromised, it's all for sale, every quiz and every lab, the midterm, probably the final too, all up for sale on the internet: https://www.chegg.com/homework-help/ques...

Arlon's CSUMB Intro to Operating Systems CST-334 Module 7 Learning Journal #7/#31 for the week Wed 08/04-Tues 08/10, year 2021 Journal spec: What to Write in your Journal Entry Write a 1 - 2 paragraph description of what you learned this seventh week in CST 334 Topic: persistence. On the topic of persistence, learning a little bit about inodes and superblocks explained a few things for me. I have a pretty good grasp of how disks work and I think talking about file system implementations is a good idea. There are lots of different kinds and I'd like to know the differences between several of them. I know some have special features. Knoppix uses ReiserFS for the data partition and I'm not sure why but I think I remember reading somewhere it has something to do with good reliability. Other than that, this week we learned video editing, narration, voice control, and that I was wrong about being right about last weeks's lab, I don't know what was wrong with it...

Arlon's CSUMB Intro to Operating Systems CST-334 Module 6 Learning Journal #6/#30 for the week Wed 07/28-Tues 08/03, year 2021 Journal spec: What to Write in your Journal Entry Write a 1 - 2 paragraph description of what you learned this fifth week in CST 334 Topic: semaphores. I think I could sum it up really quick actually - aside from all the theory - which is great - I really want to make sure I know what to put in a C program. So I sum up the theory with "use semaphores - see examples from Lab 6" and I sum up the code by saying, pass copies of the data to the threads by making a struct and mallocing for a new struct, sending the struct in to the thread as a copy of the data. The producer has 2 waits and 2 posts in the order of empty - mutex - mutex - full and consumer is full - mutex - mutex - empty and more specifically those look like sem_wait(&mutex); In between the waits and posts are puts and gets depending if it's the producer (put) or the...
