Change HTB "final qdisc" of the default walk-throught class
Hello everybody!
With a HTB qdisc:
# tc qdisc add dev eth0 root handle 99: htb
How can I change the "final qdisc" of the default walk-throught class?
# tc qdisc add dev eth0 parent 99:0 handle 88: sfq
results in: "RTNETLINK answers: Invalid argument"
CBQ automatically creates a xx:0 root class where I can attach final
qdiscs... - If there is a root class in htb, how is it

Random walk
Hi everybody,
I am trying to generate two random walks with an specific correlation,
for example, two random walks of 200 time steps with a correlation 0.7.
I built the random walks with:
x<-cumsum(rnorm(200, mean=0,sd=1))
y<-cumsum(rnorm(200, mean=0,sd=1))
but I don't know how to fix the correlation between them.
With white noise is easy to fix the correlation using the function

random walk w/ reflecting boundary: avoid control construct?
Dear expeRts,
recently I asked for a nice way to re-program a problem
without using control constructs such as "for" or
"sapply(1:length(x), ...". Is there a way to program
a random walk with a reflecting boundary without resorting
to such constructs? A working solution is
ranwalk <- function(length, bound) {
k <- cumsum(sample(c(-1, 1), length, replace=TRUE))

[PATCH] New APIs: guestfs_first_private, guestfs_next_private to walk over the private data area.
This patch adds useful APIs for walking over the private data area.
It is a prerequisite for the new event API stuff (specifically for the
language bindings for that).

Would like to ask a * user some question over voice or a walk thru in the Hou,TX area
I would like to either talk to over the phone a * admin a few question on
the deploy and a few question on the setup of * at the very least if some
doesn't mind or a walk thru of there site if there in the Houston area.
I am looking at cutting over to * for some things but I have some setup

[RFC PATCH v7 35/78] KVM: x86: disable gpa_available optimization for fetch and page-walk NPF/EPT violations
From: Mircea C?rjaliu <mcirjaliu at bitdefender.com>
This change is needed because the introspection tool can write-protect
guest page tables, exec-protect heap/stack pages and let KVM emulate
the instruction that caused these violations.

[PATCH 2/2] lib: allow to walk registry with corrupted blocks
There are some corrupted registry files that have invalid hbin cells
but are still readable. This patch makes the following changes:
* hivex_open - do not abort with complete failure if we run across a
block with invalid size (unless it's the root block). Instead just
log the event, and move on. This will allow open hives that have
apparent invalid blocks but the ones of potential
