Currently, I am enrolled in a Calculus course named Calculus and Introductory Analysis II this semester where I get to revisit various concepts of Calculus such as integrations. While I have done calculus many years ago, I never appreciated the subject nor was proficient in the subject.

Recently, I got the opportunity to attend a two-week-long training in Real-Time Programming For QNX Neutrino RTOS where I am learning the ins and outs of QNX, a real-time microkernel operating system that is a UNIX-like OS. On one of the demos, the trainer showed us a behavior that I thought was impossible. This shook the foundation of my understanding of IPC (Inter-Process Communication) and on signals. However, this is a feature in QNX that does not exist on Linux from my understanding.

TLDR:

• Intimidating at first especially to freshman students new to the University
• Prepared for a lot of Derivations
• Be comfortable with Math
• Labs take a lot of effort and time
• Do not take Monday 8am labs

TLDR:

• Intimidating at first when learning about fields
• Easier than MATH1052
• Remember Non-singularity Theorem

TLDR:

• Intimidating at first when learning about fields
• More difficult than MATH1152
• Know your delta-epsilon proofs and other definitions to prove whether a sequence or function converge

Now that classes are over for the semester, I decided to resume work on a project I’ve been putting off for a while. ProxyAuth is a passwordless authentication module that allows lazy people like me to access their machine without inputting their passwords. It authenticates the user if their hardware authenticator (i.e. a smartphone) is close to the machine via Bluetooth connection. Currently, the implementation is not convenient and there are a lot of areas that need to be worked on such as the security of the product.
