I sent a note about this a couple of weeks ago, but have not heard anything. I'm really getting a bit desperate. I have a system that I am trying to upgrade from 8.2 to 9.0. I have built it and installed the kernel, but it fails to boot. The boot freezes after probing for my hard drives during the probe of the CDROM. It just sits there, seemingly forever, though I have never waited longer

Hi, i'm new on sieve, but want to use ist with sogo. The Problem is, that when i set a redirect or vacation rule like: redirect "email at example.com"; (real Adress is different) the sieve says the mail would be forwarded, but no mail is sent. (No Action in /var/log/maillog) And because there is no Error-Message it's difficult to search for... Dovecot log ------- Jan 28

Dear best guys, I really love 5.3 in many ways but here're some unbelievable transfer rates, after I went out and bought a pair of Intel GigaBit Ethernet Cards to solve my performance problem (*laugh*): (In short, see *** below) Tests were done with two Intel GigaBit Ethernet cards (82547EI, 32bit PCI Desktop adapter MT) connected directly without a switch/hub and "device

Hello, I am trying to explore the use of random forests for classification and am certain about the interpretation of the importance measurements. When having the option "importance = T" in the randomForest call, the resulting 'importance' element matrix has four columns with the following headings: 0 - mean raw importance score of variable x for class 0 (where

Hi, i was not able to find anything about my issue in the bug-tracker, the mailinglist or the release notes. We see the following issue using samba-tool dsacl: samba-tool dsacl set --objectdn "cn=srv-client-99,cn=CoreBizClients,cn=Netzwerk,ou=muc,DC=coreboso,DC=de" --sddl='(A;CI;GA;;;DD)' new descriptor for

I would like to build a forest of regression trees to see how well some covariates predict a response variable and to examine the importance of the covariates. I have a small number of covariates (8) and large number of records (27368). The response and all of the covariates are continuous variables. A cursory examination of the covariates does not suggest they are correlated in a simple fashion

Hi, My name is Hans, I'm the product manager for Linux Magazine, http://www.linux-magazine.com. We'd like to illustrate a news item on OpenSSH 5.2 with the official logo. Would it be possible for you to provide us with a hi-res version, suitable for printing? Could you send this to me ASAP? (Our print date is already Monday, Mar 9th) Thank you very much for your help! Kind regards,

Hi, does there exists a R-function computing Hall-Wellner-Confidence-Bands? Thanks, Ralf Strobl

Hi, There is an excellent article at http://www.biomedcentral.com/1471-2105/9/307 by Stroble, et al. describing variable importance in random forests. Does anyone have any suggestions (besides imputation or removal of cases) for how to deal with data that *have* missing data for predictor variables? Below is an excerpt of some code referenced in the article. I have commented out one lin...

Howdy folks, this email is a follow-on to a 3-month-old thread about kernel page faults from the bce driver[0]. 0: http://lists.freebsd.org/pipermail/freebsd-stable/2013-March/072713.html Sorry to revive such an old thread, but a couple of bits of new information has come to light here that may be useful for others. The header splitting suggestion that Marius Strobl made[1] did fix the kernel

Hello, Since FreeBSD 9.1 I have strange problems with the distribution. Some servers are rebooting without any kernel panic, instanly. First i thought it's a problem with my KVM system, but one of my FreeBSD under a Dell R210 have the same problem. The servers concerned are now: - Monitoring server - LDAP test server - Some other servers, randomly (not in production). First i thought it's

Wouldn''t it be great if the opensolaris community creates a fs fzfs (for flash zfs) that could be the the filesystem for SDXC cards? Two main point for this are already there Sun is a member of SD Card Association and the code writting smart on a flash should be there as well with stuff of l2arc. I think that could give the opensolaris a more visiblie/ markting in the IT space and would

Hi, I have a technical question about rpart: according to Breiman et al. 1984, different costs for misclassification in CART can be modelled either by means of modifying the loss matrix or by means of using different prior probabilities for the classes, which again should have the same effect as using different weights for the response classes. What I tried was this: library(rpart)

hello, I've tried to get a backup cron-Job running, that backup up the files from the windows PC to a backup directory on the linux pc. Linux is client with ssh and rsync 2.5.5. Windows 2000 is server with openssh.34p1. I've copied additional some windows ported rsync files to c:\programme\networksimplicity\ssh\. typing "rsync -e ssh server:/ -rv client::backup" the linux
