Wtedy będę miał strumień losowych znaków ASCII. Następnie te znaki można przekonwertować na bity, jeżeli znajdzie się taki sposób.

W jakim celu ta kompresja?
Po wygenerowaniu danych do pliku data i wrzuceniu w konwerter terminal wyrzuca krzaki:

Czyli wygląda na to, że działa poprawnie. Te same pliki, gdy są mniejsze niż około 1 GB skutkują nierozpoczęciem się testów i komunikatem:
RNG_test using PractRand version 0.93
RNG = RNG_stdin, seed = 0xae0bb968
test set = normal, folding = standard(unknown format)
Segmentation fault (core dumped)
Dla większych niż 1 GB otrzymuję wciąż dużo faili i standardowy komunikat "abort()":
RNG_test using PractRand version 0.93
RNG = RNG_stdin, seed = 0x9c049a18
test set = normal, folding = standard(unknown format)
rng=RNG_stdin, seed=0x9c049a18
length= 32 megabytes (2^25 bytes), time= 3.1 seconds
Test Name Raw Processed Evaluation
BCFN(2+0,13-4,T) R= +85.2 p = 3.7e-37 FAIL !!!
BCFN(2+1,13-4,T) R= +77.8 p = 6.2e-34 FAIL !!!
BCFN(2+2,13-5,T) R= +79.5 p = 2.6e-31 FAIL !!!
BCFN(2+3,13-5,T) R= +83.6 p = 6.3e-33 FAIL !!!
BCFN(2+4,13-5,T) R= +80.2 p = 1.4e-31 FAIL !!!
BCFN(2+5,13-6,T) R= +99.5 p = 1.6e-34 FAIL !!!
BCFN(2+6,13-6,T) R=+102.2 p = 1.9e-35 FAIL !!!
BCFN(2+7,13-7,T) R=+121.8 p = 2.9e-37 FAIL !!!
Spróbuję jeszcze raz wygenerować plik 200 GB. Dlaczego wielkość pliku robi różnicę?
