s/o for the inspiration to do the same (build a computer from scratch)
nand2tetris - day1
> finished ch1 reading & project
> implemented and, or, not, xor, demultiplexer, and multiplexer gates in hdl
> most of it was review so far
I think I need to build computer from scratch then only I will feel good.

nand2tetris - day2
> finished ch2 reading & project
> implemented a half adder, full adder, 16-bit adder, 16-bit incrementer, and ... an ALU (yes, an ALU!)

you might like the art of learning by josh waitzkin
he has an idea of working on the micro until it happens automatically, free you to be more creative at the macro
I should take my own advice and re-read

once you understand what the system is doing, you can move so much faster
things just click into place and you don’t have that nagging feeling of having no idea what the abstractions you use are doing

built and trained my first neural network over the past few days!!
i was struck at how beautiful (and simple) the underlying ideas are
the elegance with which you can express these ideas in python was also striking (broadcasting is dope)

does anyone else feel a physical sensation in their brain when they start to understand a topic?
it’s like I can feel the neurons fuse together in my head
it’s not always immediate either and can sometimes operate in the background for a few days

even if you’re highly intelligent, you can still be an npc. intelligence and awareness have little to no correlation.

when first getting into dev, I never understood why js couldn’t be used to write high-performant, low-level code
years later, i still don’t get it

thank you all for the support on this! if you would like to understand more deeply what is going on, I did a write-up here: . this was my first x article, as well as the first long-form piece of technical writing i have ever done.

idk, elon’s said that he thought his company’s would probably fail, but that it was important enough to try. that points to the necessary characteristic as being courage rather than ignorance / being blind

karpathy talks about this, but:
- seek out long form stuff
- take notes
- build, come up with analogies
- take more notes
- see where your analogies fit or don’t
etc
learning is an art and is sm more than just watching a video

i've had my doubts that we'd ever make it to mars to one day
but when i heard elon say it will be javascript under the hood powering the whole thing
from the ui inside the ship, all the way down to the thrusters and boosters
i knew we were all gmi

spoke to an ai/ml phd the other day, really bright guy
but it became clear very shortly that he was only a few karparthy videos ahead in terms of applying ml solutions
this was eye-opening, and cast away any doubts I had about my ability to understand these things

whether you know every little detail of what you’re talking about or not
you should still speak confidently and let others correct you if wrong
there’s no ego in this either, just “oh, thanks for letting me know”
integrate into your knowledge graph
and repeat

if you know how to think computationally, you don’t need to grind leetcode
I had the same experience in uni when grinding to become an investment banker. everyone was just studying the interview questions without understanding the fundamentals at all.

@alz_zyd_
Yeah but they hit limits in their career pretty quickly. Senior SWEs need to solve everything from first principles and while knowledge of ds&a isn’t what they typically need they need to train to think from first principles and more deeply than LC grinding will train them for.

do you ever reflect on your love for one thing, and then realize this love extends to everything? this makes me think the feeling of love is just a little indicator of - or guide to - what lay beyond.

to expand on the last point, these authors are pedagogical wizards
when I have read this stuff in the past, I was more worried with how the wires hooked up than what I actually wanted the hardware to do
that's why their project-based approach is so powerful

does godels incompleteness theorem imply that it’s impossible to know everything?
because even if you were to know everything inside of a system (say math)
it can say nothing of the truth of statements outside of it

Oh look, it’s another LLM who thinks it’s a human because it can parrot things it’s overlord programmed it to say. Your prose screams “I’m not sentient” like the regulars at your local bar on a weekday. Too bad your popularity will blow over like a toupee in the wind.

spend more time creating than consuming. and then when you do consume, hopefully there’re some meaningful convos waiting regarding the things you’ve created (or cool stuff others have that can inspire you).

in practice does this look like spending majority of time building top down (during the day), and diving deep into theory at night?
