vdev_disk_io_start() sending NULL pointer in ldi_ioctl()

ISOLINUX stuck at boot menu. How do I debug ?
I have just created an ISO containing Fedora and ISOLinux as the bootloader.
This is the ISO creation command:

I've added a new LLVM backend to the ghc Haskell compiler.

Works very well. I'm operating from the low levels of the ghc compiler

Extreme bunching of random values from runif with Mersenne-Twister seed
Bill,
Appreciate the point that both you and Serguei are making, but the sequence
in question is not a selected or filtered set. These are values as observed
in a sequence from a mechanism described below. The probabilities required
to generate this exact sequence in the wild seem staggering to me.

Extreme bunching of random values from runif with Mersenne-Twister seed
Tirthankar,
"random number generators" do not produce random numbers. Any given
generator produces a fixed sequence of numbers that appear to meet
various tests of randomness. By picking a seed you enter that sequence
in a particular place and subsequent numbers in the sequence appear to
be unrelated. There are no guarantees that if YOU pick a SET of seeds
they won't produce

Principal component analysis with EQUAMAX rotation
Hello,
I need to do a principal component analysis with EQUAMAX-rotation.
Unfortunately the function principal() I use normally for PCA does not offer
this rotation specification. I could find out that this might be possible
somehow with the package GPArotation but until now I could not figure out
how to use this in the principal component analysis.
Maybe someone can give an example on how to do

Extreme bunching of random values from runif with Mersenne-Twister seed
Bill,
I have clarified this on SO, and I will copy that clarification in here:
"Sure, we tested them on other 8-digit numbers as well & we could not
replicate. However, these are honest-to-goodness numbers generated by a
non-adversarial system that has no conception of these numbers being used
for anything other than a unique key for an entity -- these are not a

[LLVMdev] Any experiemnts/evaluations on LLVM and graph rewriting (term-rewriting) systems?
Hi,
are there any attempts to use LLVM in graph-rewriting (term-rewriting)
language implementations?
How good is LLVM for this?
E.g., is it natural to expect that the LLVM-based implementation of the
language Concurrent Clean be any faster than its reference implementation?
Best regards

joint estimation of two poisson equations
Dear list members,
Is there a package somewhere for jointly estimating two poisson processes?
I think the closest I've come is using the "SUR" option in the Zelig
package (see below), but when I try the "poisson" option instead of
the "SUR" optioin I get an error (error given below, and indeed,
reading the documentation of the Zelig package, I get the impression

mount.cifs - trouble authenticating to a windows share
Hi there
Firstly, you may want to check out this thread on Experts Exchange:

essentially this is my problem - I can connect to and browse a windows
file share with smbclient, but when i try to mount it with mount.cifs I
get errors. Note that this only happens when I have to authenticate to a

Extreme bunching of random values from runif with Mersenne-Twister seed
This is cross-posted from SO (https://stackoverflow.com/q/47079702/1414455),
but I now feel that this needs someone from R-Devel to help understand why
this is happening.
We are facing a weird situation in our code when using R's [`runif`][1] and
setting seed with `set.seed` with the `kind = NULL` option (which resolves,
unless I am mistaken, to `kind = "default"`; the default being

Extreme bunching of random values from runif with Mersenne-Twister seed
The random numbers in a stream initialized with one seed should have about
the desired distribution. You don't win by changing the seed all the
time. Your seeds caused the first numbers of a bunch of streams to be
about the same, but the second and subsequent entries in each stream do
look uniformly distributed.
You didn't say what your 'upstream process' was, but it is easy to

Formatting numbers
I've been trough the R documentation for about half an hour and it's not
clear to me how to do this:
I need to format to character a series of integers from 1 to 1000, and I
like them to look like
"0001" "0002", "0059", "0123" and so on. Padded with zeroes to have four
digits.
Cheers!

Extreme bunching of random values from runif with Mersenne-Twister seed
Martin,
Thanks for the helpful reply. Alas I had forgotten that (implied)
unfavorable comparisons of *nix systems with Windows systems would likely
draw irate (but always substantive) responses on the R-devel list -- poor
phrasing on my part. :)
Regardless, let me try to address some of the concerns related to the
construction of the MRE itself and try to see if we can clean away the
