i'm creating android app utilizes log. i've placed file entitled "log.txt" in "raw" resource folder. have figured out how open inputstream using openrawresource , not sure how open can use printwriter it. i have tried accessing file pre-created on target device, have not succeeded. if explain me either how open resource file printwriter, i'd appreciate it. however not sure how open can use printwriter it. you can't. resources read-only @ runtime. welcome use inputstream write copy of resource's contents file on filesystem (e.g., on internal storage ), though.

i using gfortran in mingw under windows 7 (32bit) compile fortran 77 code. here minimal code contained in testequal.f file: program testequal real*8 a1, a2 a1 = 0.3d0 a2 = 0.7d0 write(*,*) 1.d0 write(*,*) a1+a2 write(*,*) a1+a2.eq.1.0 write(*,*) a1+a2.eq.1.d0 end compile with gfortran testequal.f -std=legacy the output is: 1.0000000000000000 1.0000000000000000 f f but expect 2 booleans both t. problem here? with rare exceptions, don't compare floating point numbers exact equality. rules of finite-precision floating point arithmetic not same rules of real number arithmetic. compare numbers tolerance, e.g., sum = a1 + a2 if ( abs (sum - 1.0) < 1.0d-5 ) ...

i created self-signed certificate , turned encryption on in sql server 2014: the problem sql server service won't start: this article 2010 identifies problem permissions issue: sql server service not have necessary permission read ssl cert's private key. the problem stuck on step 4 of solution proposed in article: there no group or user name matching proposed format when bring window shown in article. is there way can determine account sql server service runs under, can give permissions read ssl cert? an entirely different solution welcome too. if specify certificate, should used tls sql server, sql server windows service have read certificate and private key (the file folder %programdata%\microsoft\crypto\rsa\machinekeys ), corresponds certificate. problem is: the sql server configuration manager in not comfortable , makes not required work . thus first of 1 should localize account used sql server. 1 should start services.msc , find account ...

i have dictionary of words keys , ints value. outputs such: print (word_ratings_dict) {'hate': [1, 2, 2, 1, 1, 3, 0, 2, 3, 2, 0, 4, 1, 1], 'joy': [3, 4, 3, 3, 2, 4, 1]} for each key word in dictionary, need calculate standard deviation without using statistics module. heres have far: def menu_validate(prompt, min_val, max_val): """ produces prompt, gets input, validates input , returns value. """ while true: try: menu = int(input(prompt)) if menu >= min_val , menu <= max_val: return menu break elif menu.lower == "quit" or menu.lower == "q": quit() print("you must enter number value {} {}.".format(min_val, max_val)) except valueerror: print("you must enter number value {} {}.".format(min_val, max_val)) def open_file(prompt): """ opens ...
