I'm an old open-source independent hacker,

concerned about concepts of ethical hacking, teaching and sharing.

I like to play with shell, perl, lisp (sometime), sed and lot of other languages/environments.

Co-system administrator in several configurations, after various SMEs, I like to sometimes take time to focus on methods that I can improve or re-create (for example to change the level of abstraction).

In this, surfing on differents StackExchange's sites is a good way to boost my inspiration!

comment Difference between binary malware and script-based malware?
In interpreted language, the script is not compiled, but interpreted! But the interpreter is compiled for each architecture. See also: Interpreted languages

comment Correct way to get a number from 0-9 from a random byte?
@CodesInChaos The question seem more theoretical. Anyway someone could work on old firmware where modern PRNG simply don't exist... ( In his question, Johnny don't speak about modulo but divide by 25, which have probably not same cost ;-)

comment Correct way to get a number from 0-9 from a random byte?
Your first method use 1,02 bytes for 1 unbiaised number, your second method use 20 bytes for 1 near unbiaised number... Please have a look at my method that use only 0.8 bytes for 1 unbiaised number!

@AndreasKrey Hmm, no: By using split you have 2x63% = 125% chances of having a correct number, while instead you only obtain 98% chance by each byte read from random generator.

comment Can “cat-ing” a file be a potential security risk?
Hmmm I agree, @mr.spuratic's answer is rich. But I bring useable tools to make tests easier, (hope you've tried it)... Anyway I got my 1st gold medal \@SO with this answer! So it's good! ;-). ( P.S: If some problems with function, maybe playing with timeout (-t .01) parameter could help )

comment “No hack no fee” pen-testing agreements
... Or maybe about an amount... For that kind of challenge, the amount of money have to be very attractive! Anyway, this has nothing to do with IT security... I agree with @RoryAlsop!
