From the title, I was thinking about actual red-colored flags lol.
Well, not really an issue with the existing paragraph being hard to understand, but I would suggest more explicitly stating which symbol from the “math” section corresponds to each variable from the “code” section, at the beginning of the latter.
Hugely cool! Very clearly written too.
Haha yeah, absolutely! Might be too messy to consider it “well used” though… But it does motivate me, seeing all the signs I put there and imagining one day I will conquer that mountain. Maybe not even on the second attempt, but definitely one day.
Yes, that’s true and a better way to look at it, thanks!
Well, I was amazed by proof systems like Coq or Isabelle, that let one formally verify the correctness of their code. I learnt Coq and coded a few toy projects with it, but doing so felt pretty cumbersome. I looked at other options but none of them had a really good workflow.
So, I attempted to design one from scratch. I tried to understand Coq’s mathematical foundation and reimplement it into a simpler language with more familiar syntax and a native compiler frontend. But I rushed through it and turns out I had barely scratched the surface of the theory. Not just regarding the proof system, but also with language design in general.
I did learn a lot though. Since then I’ve been reading more about proof systems and language design in my spare time, and I’ve collected quite the stack of notes and drafts. Recently I’ve begun coding a way more polished version of that project, so on to round two I guess!
One of the largest projects under my GitHub account is an attempt at a proof-based programming language that I had to abandon because I underestimated the theoretical work involved, did not RTFM enough and months into it realized the entire thing was unsound af.
The private sector is ceasing to be China’s primary driver of growth, with that role year after year being further taken up by the state. Diminishing private funding is obviously not good, but it does align with their goal of reaching socialism by 2050. We’ll see how their economy does from now on…
Western companies outsource much of their production to countries with cheaper labor, so the really important things here are cheap raw materials and state subsidies. Since the Chinese state owns many of the large companies there, they can reduce profits throughout the supply chain or move them to other companies in the form of these subsidies. As well as use that money to build transport and green energy infrastructure, further lowering manufacturing costs.
Investors always seek short-term profit, so playing the long game is something you need aggressive policies for.
