I’ve just found a way to fight the negative thoughts in time like this: Do exercise. Though, this method probably only works with people who are free from financial issues like me. I don’t know how people who lost their jobs can handle this financial crisis. It’s terrible to think about what they have to […]
I don’t know if what I’m experiencing can be counted as depression. It’s hard for me to wake up every day. It’s just like all my energy is taken away. It’s meaningless to wake up. It’s hard for me to get my ass up and heat my food in the microwave. It’s meaningless to eat […]
I don’t really remember why I didn’t approve those comments, to be honest. Perhaps by the time I saw them, it’s been a while to be of any helps, or the commenters were asking for an IELTS help from a non-native English speaker, or it was just my friends joking around. I cannot help you […]
First of all, Scaleway sucks. Their CPU performance simply sucks. I type a character on the command line, the server tells me to wait my whole fucking life to see it render back. I thought it was due to the cheap virtual instance. Yet, I find DigitalOcean offers a slightly lower price with a much […]

(1) “A sequential circuit is an interconnection of flip-flops and gates.”. Reference: Page 28 of Computer System Architecture (3rd Edition) by M. Morris R. Mano. (2) Reference: MOD Counters and Subject 2017 – Problem 2. It seems like a mod- counter is a counter with flip-flops. And it seems to me that D-flip-flops cannot be used […]

(1) Skip (2) A worst-case example: (3) Reference: 3 & 4 & 5. It is possible to implement path compression and reduce the number of loop iterations in the “find” function. However, a linear tree is still built (and broken after one reference from lower-level nodes) and union by rank is […]
(1) (2) We see that: So: (3) (4) When the input signal is amplified into a wider range, its overall shape is less likely heavily distorted by the noise. It makes the input signal to be more tolerant against noise in communication. Reference: see slide 12-14.
