x86 - hyperledger sawtooth lake -- Intel only? -


i understand hyperledger sawtooth lake uses new secure cpu instructions achieve proof of elapsed time (poet)

does mean hyperledger sawtooth lake can used intel hardware? can other chips used?

quoting introduction section in specification:

the initial reference implementation of poet released hyperledger written abstract tee keep flexible tee implementation. specification defines concrete implementation sgx.

that means theoretical idea of poet not limited specific implementation, however, concrete implementation based on sgx (software guard extensions) is, far know, available tee (trusted execution environment) supports it.

intel sgx technology application developers protect selected code , data disclosure or modification, , enables software attest authenticity of running code. (more on sgx can found here).

sgx instructions available on 6th generation (skylake) intel core processor (or later) , requires bios support.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
