Transcript

1. Important point • There is no program that directly controls the surface temperature. • The surface temperature is self-adjusted to around the optimal growth temperature, through the executable programs behave as organisms.
2. The value of the abstraction of “organism” • I'm still considering. • I believe that if the executable programs act like organisms, it can do what typical OS can't.
3. How can “organism” stand alongside “file” and “process”? • The concepts of "file" and "process" have existed since UNIX. • The first UNIX ran on a PDP-7, an 18-bit computer from the 1960s. • These concepts don't need high performance.
4. How can “organism” stand alongside “file” and “process”? • If the concept of “organism” stands alongside there, this concept shouldn't need high performance either. • Therefore, I created a PDP-7 version of DaisyOS. • (But I will skip the demonstration because it has no user interface.)
5. Re-implement to my preferred hardware • I like retro game consoles. • I re-implemented the DaisyOS to the GameBoy. • It's an 8-bit computer from the 1989.
6. Metabolism/Motion (Execution/Evaluation) Growth (Getting 1 Byte) Multiplication (Copying) Death (Deletion) Can it multiply? Is it the lifespan? Yes No Yes No Go to the next cycle. Daisies periodic behavior
7. Metabolism/Motion (Execution/Evaluation) Growth (Getting 1 Byte) Multiplication (Copying) Death (Deletion) Can it multiply? Is it the lifespan? Yes No Yes No Go to the next cycle. Daisies periodic behavior
8. Metabolism/Motion (Execution/Evaluation) • These are the execution and evaluation of executable programs. • For the daisies, each executable program either increases or decreases the surface temperature. • Then, the resulting surface temperature is evaluated using the evaluation function.
9. Metabolism/Motion (Execution/Evaluation) In the evaluation function, • surface temp < optimal growth temp (cold for daisy) Black daisy gets a high evaluation value • surface temp > optimal growth temp (hot for daisy) White daisy gets a high evaluation value These evaluation values are referred to as “fitness”.
10. Metabolism/Motion (Execution/Evaluation) Growth (Getting 1 Byte) Multiplication (Copying) Death (Deletion) Can it multiply? Is it the lifespan? Yes No Yes No Go to the next cycle. Daisies periodic behavior
11. Growth (Getting 1 Byte) It gets “the 1 byte” according to “the probability”.
12. Growth (Getting 1 Byte) It gets “the 1 byte” according to “the probability”. • About “the 1 byte” • A byte within the sequence of machine language bytes constituting the executable program. • For example, in the case of black daisies, the sequence of machine language bytes that increase the surface temperature is 0x21 34 c0 34 00.
13. Growth (Getting 1 Byte) It gets “the 1 byte” according to “the probability”. • About “the probability” • Increases as the fitness becomes higher.
14. Metabolism/Motion (Execution/Evaluation) Growth (Getting 1 Byte) Multiplication (Copying) Death (Deletion) Can it multiply? Is it the lifespan? Yes No Yes No Go to the next cycle. Daisies periodic behavior
15. Multiplication (Copying) • When all the machine language bytes that constitute itself are got, it can “multiplication”. • Multiplication is division. (It creates a copy of itself.) • During this process, it could potentially mutate. (White daisy → Black daisy or Black daisy → White daisy)
16. Metabolism/Motion (Execution/Evaluation) Growth (Getting 1 Byte) Multiplication (Copying) Death (Deletion) Can it multiply? Is it the lifespan? Yes No Yes No Go to the next cycle. Daisies periodic behavior
17. The value of this system • The executable program rated higher by the evaluation function has a higher probability of getting 1 byte. It multiplies frequently. • The executable program rated lower by the evaluation function has a lower probability of getting 1 byte. It multiplies less frequently. To summarize this mechanism,
18. The value of this system • So, an executable program that meets the evaluation function can be generated like the mechanism of biological evolution.
19. Conclusion • In this session, I introduced the concept behind my own OS and demonstrated it. • This is not intended to replace existing OSs but to offer a different concept. • For now, it's enough if you found it interesting. • The most important thing is that it's fun.
20. That's all • Thank you for your attention. • Do you have any questions?
21. The difference between daisies and predators • Don't get 1 byte from the system. – Instead, they increase by preying on daisies. • Don't mutate.
