Some additional attacks on Cookie Session
...ng* the secret to the
data. This can be used to speed up the brute force, by precomputing
the hash of the data, and starting the hash function on the candidate
session. The correct way to use the key is to repeatedly XOR it to
the data, not append it.
5. Key Storage
One of the most common crypto truisms developers know is "Don''t store
passwords in the clear". Backups are made, files are transferred, and
the bad guys job is made too easy. In cookie_store, the app''s key is
stored directly in the clear. No ephemeral key is used. If an
attacker see''s this, it...

Community: How to deal with attempts at sabotage
Hi all,
The underlying assumption of membership in any community is that your
participation is at worst neutral, and if possible positive.
Communities, online or off, generally do what they can to protect
themselves from detrimental influences, which is where policies,
politeness, moderators, and all that come into play.
Puppet''s community has been both fortunate and awesome,

any book and tutorial about how to manipulate data with R/S+
In real world, data manipulation might take even longer time and more
effort than statistical analysis and modeling.
Does anyone know a good book and tutorial about data manupulation?
Thank you so much.

Summary: Faster way for weighted matching
I received some great ideas (see below) from a number of people to whom I am grateful. Here is the code I put together from many of their suggestions:
lx <- length(x)
lw <- length(w)
z <- matrix(abs( rep( x , lw ) - rep( w, each = lx ) ),
nrow=lw, ncol=lx, byrow=TRUE)
s <- pmax( abs( w - min(x) ), abs( w - max(x) ) )
z <- (1 - (z/rep(s,length=lx*lw))^3)^3
sums <-

[RFC] Compiled regression tests.
...IR-level test (unittests are relevant for data-structures and non-IR internals IMO) we would implement this way that we can't just implement with lit/FileCheck?
My argument is not that those tests cannot be written using FileCheck,
but tend (not all of them) to check more than relevant, may be truisms
and are difficult to reverse-engineer and to update when something
changes.

OpenSSH and keystroke timings
Old news, but ... http://lwn.net/Articles/298833/
I first posted about this back in 2001 and it's still not resolved:

1) high latency networks are a reality that will never go away. In fact they
will only become more prevalent since distributed networks continue to grow
broader but (surprise) the speed of light remains a constant.

[RFC] Compiled regression tests.
Hello LLVM community,
For testing IR passes, LLVM currently has two kinds of tests:
1. regression tests (in llvm/test); .ll files invoking opt, and
matching its text output using FileCheck.
2. unittests (in llvm/unittests); Google tests containing the IR as a
string, constructing a pass pipeline, and inspecting the output using
code.
I propose to add an additional kind of test, which I call

A challenge from a CMS implementer
Hey guys
RoR evangelists keep telling us that they have the #1 framework for
developing webapps. OK, but show us something that works and is useful
to many people out there. I could be wrong, but it doesn''t seem as if
there is anything that qualifies, as yet?
So I''ve got a little challenge for you: come up with a decent plugin
WYSIWYG visual editor for CMS. There are several

ZFS RaidZ recommendation
I have been searching this forum and just about every ZFS document i can find trying to find the answer to my questions. But i believe the answer i am looking for is not going to be documented and is probably best learned from experience.
This is my first time playing around with open solaris and ZFS. I am in the midst of replacing my home based filed server. This server hosts all of my media
