Writing an operating system kernel from scratch

I will never not find this kind of project incredibly impressive. It’s interesting to think that Linux, after all, is really just the kernel — and yet getting that work done paved the way to getting an open source version of Unix installed on billions of machines. Great stuff!

I wouldn’t call it incredibly impressive. The path on how to write a minimal multi-tasking kernel has been beaten decades ago.

Writing a kernel that can boot and do a few things is ‘just’ a matter of being somewhat smart and have some perseverance. Doing it for RISC-V complicates things a bit compared to x86, but there, too, the information about initialising the hardware often is easily obtained (for example: https://wiki.osdev.org/RISC-V_Meaty_Skeleton_with_QEMU_virt_... I wouldn’t know whether this project used that)

I think the author agrees, given (FTA) that they wrote “This is a redo of an exercise I did for my undergraduate course in operating systems”

It’s work, may be nice work, but I think everybody with a degree in software engineering could do this. Yes, the OS likely will have bugs, certainly will have rough edges, but getting something that can multi-process, with processes shielded from each other by a MMU isn’t hard anymore.

I am 99.99% sure that less than 20% of Australian graduates could do this, and honestly I wouldn't be surprised to hear that the actual answer is <1%.

I was studying at Monash, which is considered a solid university here, and holy moly are the standards low. I had classmates in the second year of my machine learning postgrad asking me things like "What is machine learning?", and they all graduated and found jobs anyway.

What did they find jobs in? Australia has like one tech company.

Which is odd since their universities have built two of the most interesting CS projects I can think of (Mercury and L4). And WWWJDIC I suppose.
