   hypothetically if the board faced enormous pressure from the public/investor and decided to reverse their decision, is this theoretically possible? of course its highly unlikely that board would do that, but I'm just asking if thi

   It's certainly plausible It's currently using wcc to compile the kernel https://github.com/wandwramp/wcc . We can swap it with gcc for sure, but require bit of work, especially the output format and backend. W

    True, agree NZ is a great place to work. In fact, I quite enjoy my lockdown-free life in NZ.

    Wow, I didn't know WAND had a github page. I'll get my fork merged with the main repo in that case. The custom fork basically adds a extra button "Quick Load", since the srec file can be quite large to transfer through s

    Depends on the audience I did struggle to explain the significance of this project when I was applying for graduate roles, especially to HR people who only look for keywards in CV. But there are people who appreciate my work. I got my inter

    OP here, Yeha I did study in Waikato. NZ is a very small market compared to the rest of the world, so there is a lot less opportunities here in NZ in terms of number of startups and number of tech firms. The salary is also lower compared to

    That's a very smart way of debugging concurrency. I did a lot of logging as well when I was doing debugging concurrency. Overtime once you got familar with the projects, I started to develope instincts on how everything fits together.

    Thanks. The OS is roughly 90% compliant with POSIX.1, but there's still a lot of work to make it fully compliant. That would probably be my next goal. This is a hobby project, I will probably spend 1-4 horus every other week to work on

    I agree, X86 is too complex with its legacy hardware and obscure instructions and environments. It might not be a good starting place to develope hobby projects. The OS is running in a customised RISV hardware in MIPS for educational purpos

    The hardest part is debugging concurrency and weird scheduling bug. It's hard to debug because I can't reproduce it, which is quite frustrating. Over time, I found that making educated guesses, or running the code in my brain, it

    Author here, this project is just for fun, nothing more than that. The OS is designed for MIPS architecture at this stage, I don't think tcc supports MIPS at the moment.
