Heyyo! Today, super short!
Sleep -> wake up -> study and YouTube. For the whole day. It was lovely weather, so it was kinda a shame, what I did, but yeah.
At lunch, we talked about what would happen after death. Or if anything at all would happen. My brother said, that he thinks that nothing’s gonna happen. And this made me sad… Since I think this is a really sad world view. This actually stood with me throughout the day.
I just think, I wouldn’t want to “lose” him, if he dies. I think it’d be nice, to see him even after death. Even though, this kinda independent of whether we believe in it or not… Made me sad nonetheless.
In the afternoon, I finally wrote a driving instructor for lessons. Nice!
I was feeling, like getting a new girlfriend, and I told myself, that I’ll start looking, once I have my drivers license. So today, the motivation finally kicked!
In the evening, it got really windy, so I closed all the windows in the house, and tidied up a bit outside, so nothing’s gonna break. It was the first “storm” this year. That means, I saw like 10-20 lightnings. According to my counting, they were like 1.5-5 km away from my home (the nearest ones).
What did I study? Computer architecture. I give you a quick overview, so I repeat it once, before going to bed.
1. Some basic C stuff.
2. CISC vs RISC
complex vs reduced instruction set computer – so, either a lot of possible instructions, which might be slower (per usage) and consume more energy, but you have to use less overall. VERSUS less instructions, but it’s easier to compile code into those & the other previously named.
3. MIPS Instruction set Architecture
Three kinds of instrcutions. R-, I-, and J- format (for arithmetic, immediate (which is arithmetic with a constant, which you immediately load), and jump (for if and else and so on)). And then how these get interpreted and shit
4. Performance (Nothing mentionable here)
5. MIPS basic architecture
A first intuitive implementation of a architecture (so only with add, or, ori(mmediate), and, andi, and some more), and how you can use the single cycle design vs multi cycle design (Slower cycles, but more gets done in a given cycle; downside: you might have to wait doing nothing, until a cycle is done. VERSUS, multi-cycle where you break everything down into micro-cycles, and then you can pack it more concise, with the downside, that it’s a little slower for long instructions. For example a lw (loadword) would take 5 cycles, which is about 1.1 single-cycle cycle; but an add would take 3 cycles, which is about .6 single-cycle cycle.
Real quick shift here. During dinner, my sister, Leah told us, that she used to date a hobby-boxer, LIKE 3 YEARS AGO. Which none of us knew. This was quite surprising – but also fitting, since a few days ago, she said, that she would only introduce her boyfriend if they were engaged. LOL. Only, because she doesn’t want him to ask our dad if he can marry her. Whack reason. NGL.
But yeah. That’s all for today. I’ll see you again tomorrow! Take care & Bye-Bye!
Check-List Time
- Thinking about ex: 3/10 bad, early evening, it was amazing. I even thought about getting a new one, but then, some time later, I got more sad again :( not that bad though
- Shoulder pain: pretty much same as yesterday
- Knee pain: My right knee hurt today. I guess, I should go to the gym sometime soon to make it go away.
- How was my day? 6/10. Felt pretty good. Was not as efficient studying as I had hoped but happens.
- How short was the entry? Not short at all. I see. If I write, it’s gonna be short, it’ll be a long entry. haha
