  • variables in assembler

    - by stupid_idiot
    hi, i know this is kinda retarded but I just can't figure it out. I'm debugging this: xor eax,eax mov ah,[var1] mov al,[var2] call addition stop: jmp stop var1: db 5 var2: db 6 addition: add ah,al ret the numbers that I find on addresses var1 and var2 are 0x0E and 0x07. I know it's not segmented, but that ain't reason for it to do such escapades, because the addition call works just fine. Could you please explain to me where is my mistake?

  • Python beginner confused by a complex line of code

    - by Protean
    I understand the gist of the code, that it forms permutations; however, I was wondering if someone could explain exactly what is going on in the return statement. def perm(l): sz = len(l) print (l) if sz <= 1: print ('sz <= 1') return [l] return [p[:i]+[l[0]]+p[i:] for i in range(sz) for p in perm(l[1:])]

  • Why don't all XSLT templates get executed at once?

    - by Matt W
    Refer to: http://stackoverflow.com/questions/1613454/retrieving-one-element-and-filter-by-another In the above linked posting, I don't understand why the two template blocks don't get executed upon in the incoming XML at the same time. As far I can can see, the XSL risks the second template executing for every Document element whether it is called with apply-templates or not. Could someone explain this to my stifled brain, please? Thanks, Matt.

    - by calccrypto
    Can someone explain how the RC2 key schedule works (particularly the very beginning of it)? i know it uses little endian, but my implementation is not working for any key except "0000 0000 0000 0000" Test Vector Key = 88bc a90e 9087 5a Plaintext = 0000 0000 0000 0000 Ciphertext = 6ccf 4308 974c 267f im assuming that the first thing to do with the key would be to change it into bc88 0ea9 8790 5a and yes i know RC2 is not even used anymore, but i would still like to know
