Too bad the author used Wordpress instead of Zola. Otherwise, his next post could be "Blogging about writing Pong in Rust in my OS written in Rust in a blog engine written in Rust".

...served from a Warp server written in Rust...

This is the first time I've seen pong not written in assembly.

I still have a VHDL version lying around from my old student project. :)

Wasn’t the original “written” using discrete logic (as in, no ROM)? How close to the original is your VHDL version then?

Since it's a student project to learn about VHDL and synthesis the pong clone had a few additions like simple math-expression based textures and we ignored trying to get close to the exact movement behaviour. But you actually get to control it with rotation based input. :)

In regards to ROM. It was an FPGA, meaning it was reprogrammed on every startup. But all behaviour was built as logic without accessing any memory.

Am inspired how can I learn how to write a RISC-V OS?

Is it alot of work?

The very first link in the post is to https://osblog.stephenmarz.com/, which is the author's tutorial on doing so. You should check it out!

Tsinghua University has a course about writing OS on RISC-V by Rust.

However you probably needs Google Translate to read it since it’s written in Chinese.

n-gate is going to have a field day with this one

I never heard of n-gate before. I've just lost two hours of work I have to make up tonight! Funny stuff.

It's Rust all the way down!

When Christ returns from vacation, He wants everything, including the Bible, to be rewritten on Rust.

"And he who dares write Unsafe code shall be strung up and scourged. His limbs broken, his flesh stripped from his body, and his eyes pierced. For he has defiled the glory of Rust, and the righteous should not suffer such a man to live."

Rust is already used in Bible (6 or 7 times).

Ezekiel 24:6 Therefore thus says the Lord Yahweh: Woe to the bloody city, to the caldron whose rust is therein, and whose rust is not gone out of it! take out of it piece after piece; No lot is fallen on it.

Sure but Matthew 6:19-20 clearly indicates that Rust is too powerful for man and can only be used after ascending to live amongst the angels:

“Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal;

but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal.“
