I'm not a contributor to the U-S project, but I have been monitoring
alternative python implementations' progress some, and seem to be adding
something to pypy all of a sudden.
I think unladen swallow has produced performance improvements, and they are
likely to be merged into cpython 3.3.

Here's -a- way to try - not necessarily the best way:
1) Write a little gcc .c with inline assembler, to make your EAX change
2) Call it from CPython using ctypes
However, by the time you return from the code that makes your change and
resume execution in the CPython interpreter, EAX may well have
What's the best way of reading lines of null terminated (ASCII NUL, \0) text

I've been using http://stromberg.dnsalias.org/~strombrg/readline0.html with
2.x, but I'm moving some of my stuff to 3.x, and am wondering if there's a
way that would obviate readline0.
I've got a couple of programs that read filenames from stdin, and then
open those files and do things with them. These programs sort of do
the *ix xargs thing, without requiring xargs.
In Python 2, these work well. Irrespective of how filenames are
encoded, things are opened OK, because it's all

If it's a big list and you're checking multiple times, you're probably
better off converting the list to a set, and using "in" on the set. Once
you have your list converted to a set, you can update both quickly.

IIRC, this is an instance of what's called "source routing", and was
largely shut off after network admins realized it was a security
issue.
Of course, if you have root/administrator permission, you could
probably do it. But if you have that, you could probably just fix the
routing table.

I prefer special symbol "congestion" to special symbol proliferation. A
lot. A language with few special symbols looks less like line noise, is
easier to read and write, and is easier to google for answers about.

I'm not sure of the specifics, but you may find that you can do this with
the syslog module - may require reconfiguring syslog.conf or the equivalent
though. If you hit an appropriate facility and level, you likely will see
syslog messages go to the kernel's dmesg ring buffer.

You probably should tell us what GUI toolkit you're using.
But if your GUI toolkit has the concept of a "vertical box", then create a
vertical box, add it to your window, and put things in the vertical box.
To put your widget at the bottom of your vertical box, append to the end it
last or insert

I don't think #!/usr/bin/env python is the right thing - unless a script
really doesn't care much what version of python it gets.
I used to #!/usr/bin/env everything, but I've been updating my old scripts
not to. It's just too much trouble, despite the one minor simplification it
provides.

You could probably:
cd to dir1
getcwd
cd to dir2
getcwd
repeat
cd ..
getcwd
if getcwd == dir1's cwd, then under
until at /
cd to dir1
repeat
cd ..
getcwd
if getcwd == dir2's cwd, then under
until at /
This should deal with symlinks and junctions, as long as you aren't worried
