This document has most of the explanations about the input format: https://github.com/riscv-non-isa/riscv-asm-manual/blob/master/riscv-asm.md. There are some small missing bits but all the directives like .text are there.

The is a C and C++ toolchain available https://github.com/riscv-collab/riscv-gnu-toolchain If you feeling brave, https://github.com/riscv-non-isa/riscv-asm-manual/blob/master/riscv-asm.md

> Note: "jalr zero, 1b" can also be written as "j 1b", "jalr zero, 0(ra)" can be written as "ret"

`j` and `ret` are so-called "pseudo instructions" [1], not compressed instructions.

Pseudo instructions are just shortcuts used in assembly language to pretend that some common operations really "exist" with the need to type (or display) the real, more complex instructions. `nop` is a common pseudo instruction. RISC-V has `nop` instructions, but, instead, the "do nothing instruction" is canonically encoded as `addi x0, x0, 0`.

The compressed instruction set (a.k.a "extension C") is a subset of the full [2] instruction set, in which a restricted combinations of operands are possible. The assembly (human readable) code of the compressed instruction set looks similar to that of the full instruction set (including pseudo instructions), but they are encoded as completely different binary sequences.

If you are going the broad CS route, do you want a degree, or do you just want the knowledge? If you want a degree, maybe start at a JC, then transfer to a UC or CSU (locally...Sac State). If you just want the knowledge, there are a number of websites out there like OSSU or Teach Yourself CS or this one on Github.

Here are pretty much all the classes you would need to take to get a computer science degree.

I'm self-studying, and stuck between taking online calculus courses or use UK textbooks to learn further maths. I'm learning maths for a career in CS, following advice online(loose guidelines from a github). Most sources say to learn calculus for CS, however I've seen that A-Level maths is calculus and further maths is less calculus? I'm just confused, there are resources for calculus online so I could do either. My other line of thinking is that if UK has maths/further maths then that must be enough for Universities here... If anyone can give any advice or just point me in the right direction that would be great!

Also check this repository out. It has some useful resources that will give you an edge over others. https://github.com/ForrestKnight/open-source-cs Don't use it right now. Start it when you have learnt a bit of HTML, CSS, Javascript. When you become familiar with these and have built some projects then you will need to up your game. At that point you will be needing this repository.

You're in luck!! https://github.com/ForrestKnight/open-source-cs

https://github.com/ForrestKnight/open-source-cs is getting on a bit, but a lot of great info.

Although, I am a current comp-sci student, I'm self-learning how to program and self-preparing myself to be job ready. Although, it has definitely been proven possible to achieve this without a computer science education, if anyone who wants to join the group is interested in that, following this free program🎓 while learning to code, would be pretty much the same curriculum that I'm taking at university.
