I'll pay to create a raspberry pie os!

Sat Aug 24, 2019 5:49 pm

Hii guys :D

I'm currently working on a project to help schools teach programming!
I need to create an os for raspberry pie 3b+ and have trouble starting one.

If you are interested than contact me to this email:

Well, what's your budget?

What’s wrong with the current ones given they have lots of programming options and are free :?:

Do you mean help in setting up the systems rather than an operating system?

Creating an OS from scratch will cost you millions of man-hours, its not a sensitive proposal.

It depends what that OS needs to do, how one is defining an OS. I don't believe it would take 170 man-years for a single person to create an OS. Ultibo seems the most applicable example to point to as to what can be created on a Pi with enough skills to do it.

It is probably time to update all bare metal tutorials which were intended for original Pi A's and B's, or other non-latest boards. But I doubt it's going to happen.

I'm more thinking that some organisation would need 170 man to design something approaching a modern OS in one year, To be realistic though I think you would need many more people than just 170 persons to do so, how many people work for Microsoft, and how long do they need to write a new OS from scratch.

I can't imagine the OP really asked someone to "write a practical OS for schools to teach programming", or that he thought he could do so himself with some help. at a very minimum this would include a filing system, an editor, compilers, and a simple GUI, And much more if he wants to improve upon what can be done with raspbian.
Note that he has not returned here to explain what he wants.
perhaps he wants to write another minix? https://en.wikipedia.org/wiki/MINIX

buy a copy of "Modern Operating systems" by AS Tanembaum. 20+ years ago it was the goto text book for O/S 101 classes. The source code for what became linux (minix) is in the appendix
Minix = linux minus networking, tho there is a bit more to it ;)

Yep but I think this can be done now.
Because none of this has to be done from scratch.
There are now tool sets that could allow one person to do it ;)

I don't think a compiler is needed, with 1GHz CPU's to play with a shell interpreter might be enough to be useful.
It will still take time but not man years, perhaps weeks.
It is only for educational purpose not controlling reactors.

Most of the baremetal guys could do it with their existing code.
The only thing they need to add would be a sort of shell scripting.
Basically Kernels become CLI OS's once something like Bash is added.
GUI's are a much bigger mess on top of that.
I'll bet the OP is sitting back laughing at all the mugs who took him seriously............
I have been taking this seriously before the OP posted.
And yes I have read those books recently, mostly boring old ways, starting with a serial console.
We can have lots of serial consoles on the Pi4 :D
I think serial console is already working in the existing C, C++, Rust, Pascal baremetal solutions.

Minix would be Cool on Pi's as an alternative to Linux.
Remember it was written for an educational purpose.
But this is old stuff, surely newer Microkernels would be more suitable for educational use?
What is the modern equivalent of Oberon?

I have been doing a bit of OpenGL coding recently, what has stuck me is how language agnostic it is.
The code is nearly identical between C, Rust, Go, Pascal.
Could an OpenOS be done the same way?
Just a simple toy OS us kiddies can play with, nothing serious :lol:

I found an online scan of that book on a Romanian website (I'll leave it for other to find that with Google).

It points to http://www.minix3.org/ which has the full MINIX source code (no copy typing needed). But, you will need to work on porting it from a Beaglebone to a Raspberry.

On the forums I administer I tend not to worry too much about trolling posts unless intended to incite flame wars or really waste time and effort.

Though a poster may be trolling there are likely others who may, or one day will, be thinking the same, with genuine intent. As long as information in replies is useful it serves a useful purpose. It all helps build the knowledge base.

And when that's useful to someone, contributors and the community get the last laugh.

Jennifer will be happy to provide a solution for a price?

Why not let the kids make they own OS?
Give them Pi's and Internet access and let them loose.
They won't be handicapped by old knowledge, put them in small groups
Bit of competition to see who makes the best?

This sort of stuff the educator should just point them in a direction and not impose limits.

In a junior year OS theory class (back in 1974 :)) the first semester was spent learning OS design/theory.
The second semester, we had only one task: design, code, test, and demonstrate a functional operating system.
We (12 of us, IIRC) did that, on an IBM 370. It took almost the entire semester.
All it could do was IPL, interface with the system console, respond to a few simple operator commands, read from a card reader, and write the input to a an IBM 1403 printer. Pretty simple and not too impressive.
I think what got all 12 of us A's: we made the 1403 sing a song before shutdown.
At least 3 of us got jobs at IBM (or later Amdahl) doing really neat stuff, in the parlance of the day.

Creating an OS from scratch, in almost no time, for a school class is insane of course. However...

Once again it's time to revisit a microkernel design for robustness, ease of understanding and security. It would also be novel, with reliability , correctness and security in mind to write, said OS in a modern "safe" language rather than create another hack job in C.

Oddly enough somebody, Jeremy Soller, has already made a good start on that: Redox OS: https://www.redox-os.org

I think there has been some effort to port Redox to the Raspberry Pi. It would be great if the bare metal gurus here would lend a hand with that.
https://www.redox-os.org/rsoc/

My only operating system experience was writing a "kernel" for a home made 6809 board back in 1980, two of us got a a program loader going, from cassette tape, a debugger with breakpoints and the like, the terminal interface of course.

I did once get a Intel 386 board to boot up and switch from 16 bit to 32 bit protected mode then run some tasks, all in assembler, that was hard enough for me!
Memory in C++ is a leaky abstraction .
