model seleciton by leave-one-out cross-validation
Hi, all
When I am using mle.cv(wle), I find a interesting problem: I can't do
leave-one-out cross-validation with mle.cv(wle). I will illustrate the
problem as following:
> xx=matrix(rnorm(20*3),ncol=3)
> bb=c(1,2,0)
> yy=xx%*%bb+rnorm(20,0,0.001)+0
> summary(mle.cv(yy~xx,split=nrow(xx)-1,monte.carlo=2*nrow(xx),verbose=T),
num.max=1)[[1]]

[PATCH 0/2] ocfs2: two bug fixes about xattr and inline-data
Mark and Joel,
I found two serious bugs about xattr and inline-data.
the first bug:
in ocfs2_mknod(), we check and found the ACL or security xattr entry
could be set into inode in ocfs2_calc_xattr_init(), then don't reserve
block for them. But in ocfs2_mknod_locked(), if we found ocfs2 support
inline-data, then set id_count with the max_inline_data. After that, we
set acl/security xattr

RFC: xencomm in common
Hi,
xencomm is the ppc infrastructure to do hypercalls with guest physical
addresses instead of virtual address.
Because ia64 should also use physicall address, I think it''s better to re-use
the ppc code and to put into common code.
I''d propose to submit this patch is every part is OK (ie no NAK).
This patch creates include/xen/xencomm_access.h which is to be included by

persistance of factor levels in a data frame
Hi,
Just something I don't understand:
data <- data.frame(V1=c(1:12),F1=c(rep("a",4),rep("b",4),rep("c",4)))
data_ac <- data[which(data$F1 !="b"), ]
levels(data_ac$F1)
Why the level "b" is always present ?
thanks

[PATCH 0/4] ocfs2: bugfix for hard readonly mount
Hi, All,
These four patches are all related to ocfs2 on hard readonly mount.
patch 1 fix oops when umount ocfs2 on hard readonly device.
Because ocfs2_dismount_volume() will call ocfs2_cluster_hangup() and
then call ocfs2_stack_driver_put(), will hit BUG_ON(active_stack == NULL).
patch 2 fix oops when do ls or cat in ocfs2 on hard readonly device.
Because ocfs2_open_lock() will call

[PATCH] ocfs2: Use the right access_* method in ctime update of xattr.
In ctime updating of xattr, it use the wrong type of access for
inode, so use ocfs2_journal_access_di instead.

[PATCH 1/1] O2net: Disallow o2net accept connection request from itself.
Currently, o2net_accept_one() is allowed to accept a connection from
listening node itself, such a fake connection will not be successfully
established due to no handshake detected afterwards, and later end up
with triggering connecting worker in a loop.
We're going to fix this by treating such connection request as 'invalid',
since we've got no chance of requesting connection

[PATCH 1/1] Ocfs2: Teach 'coherency=full' O_DIRECT writes to correctly up_read i_alloc_sem.
Former logic of ocfs2_file_aio_write() was a bit stricky to unlock the rw_lock
and i_alloc_sem, by using some private bits in struct 'iocb' to communite with
ocfs2_dio_end_io(), it did work before we introduce the patch of supporting
'coherency=full,buffered' option, since rw_lock and i_alloc_sem were never
acquired both at the same time, no mattar we doing buffered or direct IO or

Duplicates when switching from Qpopper to Dovecot pop3
Hi All,
Our test users re-download the mail they've left on the server when they switch from Qpopper to Dovecot. Qpopper includes the X-UIDL header - X-UIDL: X8V"!E)<"!58?"!"9C"! - on read messages. Any suggestions are appreciated. I've included my dovecot configuration.
Thank you,

Flac multi channel
Hi Guys,
I know that FLAC format is currently limited to 8 channels but I was
wondering if this hard limitation of the format
or if it can be easily circumvented if the flac library is compiled with
other settings and/or the software using it don't mind it
Thanks !

[Xen-ia64-devel] flush_tlb_mask and grant_table on ia64
Hi,
on IA64 flushing the whole TLB is very expensive: this is a cpu tlb flush and
clearing 16MB of memory (virtual tlb).
However, flushing an address range is rather cheap. Flushing an address range
on every processors is also cheap (no IPI).
Unfortunatly Xen common code flushes the whole TLB after unmapping grant
reference.
Currently, this is not done on IA64 because domain_dirty_cpumask

Non-destructive deduplication
Greetings.
I use Dovecot 2.2.29.1 as my IMAP server. Owing to a bug in my mail
client [1], several unique messages (mostly in my Sent folder) have
duplicate Message-ID headers. Dovecot itself doesn't seem to be
bothered by this, though my mail client is confused by the false
duplicates. (It screws up the threading display, and results in data
loss when I run the client's deduplication

[PATCH 1/3] VFS/ioctl: Add punching-hole support to ioctl().
We're currently support two paths from VFS to preallocate unwritten
extents(from FS_IOC_RESVSP, or fallocate()), likewise, behavior of
punching-hole should be treated as the same, this patch tries to teach
file_ioctl() to handle FS_IOC_UNRESVSP, underlying filesystem like ocfs2
is wise enough to do the rest of work;-)
