I am new to Ruby and I could use some expert advice as to how I can make this code run faster.

Presenting lies as reality, among many other reasons, is what makes
you a troll. Something like "I can code Windows services usign Python
if I wanted to but I cannot code Windows services using Ruby whether
I wanted to or not" is nothing more than a lie.

Here's my version in FreeBasic.

dim outname as string
dim as integer in_handle, out_handle, i, size
dim buffer( 0 to BUF_SIZE - 1 ) as byte
dim p as longint ptr
outname = filename & ".scrambled"
in_handle = freefile
if open( filename, for binary access read, as in_handle) then
? "Can't read "; filename
end 2
end if
out_handle = freefile
if open( outname, for binary access write as out_handle) then
? "Can't write to "; outname
close in_handle
end 4
end if
while not eof( in_handle )
size = seek( in_handle )
get #in_handle, , buffer()
size = seek( in_handle ) - size
p = @buffer(0)
while p < @buffer( BUF_SIZE )
*p = *p or &h8080808080808080
p += 1
wend
if put( #out_handle, , buffer(0), size ) then
? "Failed while writing to "; outname
exit while
end if
wend
close '-- Caution. Closes all open files.
return 0.0
end function
if command(1) = "" then
? "Give me a filename next time."
end 1
end if
print -timer + scramble( command(1) ) + timer

I don't think that's quite accurate. An opinion that ruby is not theEric said:
fastest of languages is hardly unwelcome. Such a thoroughly
undiplomatic tone of voice, however, is.

If you google for

http://www.google.com/search?q=ps2QrAMAAAA6_jCuRt2JEIpn5Otqf_w0
which is the google posting-account number for "Ruby Maniac" in his
headers you find this guy is a profi troll. Some of his posts to other
groups are racist, sexist and highly offensive.
I suggest no further responses to his posts.
Any way to get this id filtered from the list?

Ooops looks like I am wrong here. It seems that the id is a generic

all have that same id.
I guess I have to appologize to Mr Ruby Maniac for possibly accusing him

Well I did accuse him of using Racist and sexist language in other
Groups which I now have no proof of so I should apologize for that. Even
trolls have the right to be treated humanely.
It is just when I googled that ID I came up with article after article
about trolls on other groups. Other people were making the connection,
incorrectly, about the posting-id and I jumped to the same conclusions
cause it fitted what I wanted to believe.

Yes of course, but I thought that he deserved my remark by all means.
Sorry if it was posted against you, that was indeed a little bit

I find that a little difficult to believe (re: "global warming
denialists"). Such a statement mostly just sounds like a derivation of a
great many ad hominem fallacies adding up to a conspiracy theory. Have
you come across some evidence of such a phenomenon?
Every single person I've come across who questions the "global warming
consensus" actually has excellent credentials. Of course, I haven't
really looked into the matter enough to have a comprehensive sense of
people who disagree it's a settled matter, so there could very well be
some astroturfers out there -- but I haven't seen any evidence of such.
