Re: Dangerous UDP Checksum code ?!?

[Skybuck Flying]

I think I've been redcoding a bit too much ;)

In redcode there is no such thing as temporarely variables created by the
compiler... ;)

So in recode any operation is done directly on whatever was specified ;)

So I guess I got a bit worried that direct operations could happen in high
level languages as well ;)

At least the solution I posted could be easily ported to for example
redcode/asm without any doubts/problems ;) :) So I am sticking with my
solution ! ;)

Bye,

If you want to spend the rest of your life writing mind-numbingly dumb
code, knock yourself out. For for the rest of us sane people, if this
is pretty gosh darned simple:

sum = (sum & 0xFFFF)+(sum >16);

Frankly, it's a miracle that anyone was able to misunderstand it. But
then, you never cease to impress.

Skybly has made a multi-year career of Usenet vandalism.
On each newsgroup where I have seen hir, the pattern has been
the same: A few semi-reasonable posts to provide adequate
lubrication, followed by an affirmation of the surname (with
the obvious edit). The suggested remedy is to update your
killfiles; would that it were possible to set them on something
stronger than "Stun."
