Those of you who were at the clinic last night know that I
was asking for help on a weird limitation of Python.
The problem: Consider the function, foo(), in this C program.
#include stdio.h
int foo()
{
static int n = 0;
return ++n;
}
There's an analysis of the topic at developerworks:

I'm trying to get sendmail setup (under RedHat for now) and I'm having
a problem with the X-Authentication warning when I'm sending from a
transient host. Is there something in my setup that I can change that
prevents the warning from showing up in my emails, or do I have to fix
my DNS settings?

I'm setting up a firewall/gateway at my house.
What should I use? IPchains? What's the other option? Isn't there a
standard packet filter for 2.2 and a different one for 2.4? I'm in the
kernel config for 2.4.19 right now and don't see much.

Use iptables, don't bother with ipchains. Both are in 2.4. Look for ip
netfilter setup under the networking options.
Turn on network packet filter (replaces ipchains)
then into netfilter config
select
connection tracking
ftp/irc (if you plan to use those over nat)
iptables support

There are many options here. Depends on what you want it to do,
really.
My suggestion, if you aren't planning on running anything special
on it would be one of the various firewall boot disks or boot cds. The
reason for this is that a hacker who breaks into a boot cd can't
Here's an well-commented example of iptables setup, that includes info
about loading modules:

There we go. That's the kernel stuff I was looking for. :)
Anyone ever try Gibraltar -- a debian based firewall bootable CD?

Today I installed Debian Woody from the bootable CD. That's the first time
I used it and it went well. Definitely beats throwing away old floppies b/c

I apt-get installed a 2.4.x kernel so it would pull in any other utilities

I've never had to make one with debian, nor have it ask for one. I've read
that the only thing it does is load modules required at boot. However I
compile filesystem modules into the kernel, and also add in support for the
kernel autoloader. It's never complained about needing an initrd.img.

initrd == Initial RAMdisk. It's an ext2 filesystem which lilo loads
into memory at boot time. You can look at the contents like this.

Now that's a weird one. So this code, e.g., is a sign of trouble?

what is this? Is the 'image' tag at the end a means of verifying the

show up in mutt, I had to do a 'v'to even see that it was there.
