Hi all, I used the following code and data to get auc values for two sets of predictions: library(caret) > table(predicted1, trainy) trainy hard soft 1 27 0 2 11 99 > aucRoc(roc(predicted1, trainy)) [1] 0.5 > table(predicted2, trainy) trainy hard soft 1 27 2 2 11 97 > aucRoc(roc(predicted2, trainy)) [1] 0.8451621 predicted1: 1 1 2

I am trying to set up an ipsec net-to-net VPN and am having problems. Here is a diagram of the setup: LAN A --> Host A ----> Internet <---- Host B <-- LAN B LAN A = 10.10.2.0/24 LAN A gateway = 10.10.2.254 Host A internal = 10.10.2.254 Host A external = xx.xx.xx.xx Host B external (see below) Host B internal = 10.10.1.10 LAN B = 10.10.1.0/24 LAN B gateway = 10.10.1.252 (F5 Big

Hello, I have a problem with rsync and hard links : I have 1 folder : P, with 2 subfolders : S1 and S2 S2 contains a lot of hard links to file stored in folder S1. P : -S1 -S2 (S2 files hard links to S1 files) I would like to rsync the folder P to another computer, but each sub folder S1 (110 Go) and S2 (10 Go + hard link to 100 Go of S1) contains thousands of thousands of

Has anyone created or rebuilt a Linux Software RAID having mirrored partitions on unequal sized hard disks ? There is a CentOS 5 server having two 400 GB hard disks with five mirrored partitions (software RAID 1) and one of the hard disks is dying. Since new 400 GB HDDs are not available here, we are exploring the possibility of replacing the faulty hard disk with one of a higher capacity (500 GB

Hello, I recently built a System out of old Computer parts I had. I installed Ubuntu 9.10 in it. I built it for sharing all my files with my other computer at home. I'm tired of having so many external Hard Drives. So, I built this new/old system and installed an old Seagate 500GB hard drive I've just RMAed. I'm able to share all my files with Windows Vista & 7 without any issues

Hi, I'm having a problem using --link-dest and --hard-links when the fs hits the hard link limit (link(2) returns EMLINK). Using rsync 3.0.7 an error is thrown and the target file is not created. Glancing at git head it _looks_ like things could now be a little nicer. Perhaps the target file is copied instead of hard linked when hardlinking fails -- I've not tested it. Anyway, the

I''ve been thinking about this for a while, from a perspective of how to make it work by allocating i-node numbers from a global pool, but yesterday I realized that offering the feature would be a bad idea because it violates the semantics of file systems. I will be happy to expand on that point if anyone disagrees with it. dln -- "It is merely a matter of persistence." --

Hi All, I need some advice on finding a solution to this problem . I have a hard disk mounted on a mobile robot. I am using ext3 fs. The hard disk is subjected to several bumps as the robot travels. I am experiencing frequent hard disk failure ( about once a month). I have thought about 2 different solutions to this problem. I would appreciate any tips on evaluating them 1) Use Compact Flash

In my Cent OS machine, I have 3 hard drives, an 80, and two 200gig hard drives. One of the drives is obviously starting to fail, but I'm not sure which one. Is there a command line command in Linux that will check the drive integrity on all the hard drives and tell me which one is going bad? Thanks Jim

Hi, I have 2 Suggestion for rsync. 1)You should have a feature that enables rsync to be able to manage a cluster of web servers with load balancers, so if a person has 100 web servers connected together and running them as a cluster with load balancers, rsync will mount all the hard-drives of the 100 web servers together so they appear as 1 big hard drive. So when a person accesses their website

hello every body, I'm trying to build an isohybrid image based on syslinux able to boot on bios and uefi with optical disk or usb key. I've build a 16Mb hard disk image (core.img) with necessary parts for bios (legacy bootable partition, protective mbr, gptmbr.bin & syslinux installation) and for uefi (gpt, esp, /efi/boot/bootx64.efi & syslinux files). my hard disk image is ok -

Hi, I want to use rsync in a may be unusual way: I have a source tree containing lots of symbolic links and I use the option "--copy-links" to get the physical files (the referents of the symlinks) on the target host. As the host uses the synchronized files in a read-only fashion, I also want to get hardlinks for all identical files, to save space. Thus I also use

smartctl, hdparm, and sdparm all are valuable tools to obtain hard drive info. But, they don't seem to work, at least, on obtaining hard drive info from drives on a Dell PERC controller. Instead, I'm given basic PERC controller info, not drive info. Is there a tool to let me get the hard drive make/model/serial numbers from a hardware RAID setup? Thanks. Scott

I'm trying to learn Asterisk (specifically Trixbox) and, as you probably know, it runs on CentOS. I want to run it on my laptop and thought that I could install it to an external USB hard drive, like I've done with Fedora 12 and Linux Mint 8 (I like to keep my small CentOS/Windows dual booting hard drive in the laptop's hard drive slot). But it won't work. It kept giving me hard

Hi, The title says it all. One of my clients showed me a 120 GB hard drive that his daughter accidentally formatted, according to him. I booted the first CD I had at hand - a Slackware 11.0 install CD - and launched cdfdisk /dev/hda. cfdisk informed me that there was even no partition table. So much for reformatting. cfdisk only shows me 120 GB of free space. Any way to retrive data on this

Version 2 of these patches includes optimisations suggested by H Peter Alvin to save bytes: * Use memory-mapped I/O register to read keyboard shift flags * Don't reload DX from memory; move immediate byte to register Tested using mbr.bin. TJ (3): mbr: Ctrl-key press forces load from first hard disk gptmbr: Ctrl-key press forces load from first hard disk isohdpfx: Ctrl-key press

Is it possible to configure syslinux.cfg on a floppy to start Win98 on a secondary hard drive? If so, how is this done? Currently I have Linux and Win98 on the primary hard drive, and when I attempt to use the floppy to start Win98 on the second hard drive, I simply start Win98 on the first drive. I have tried many different approaches, all to no avail, and I would really appreciate some

Hi, I have a new labtop and i want to install CentOS 7.6 on it. My labtop has two hard drives : - A 256Go SSD - A standard 1 To hard drive None of the two hard drives are detected by the Centos installer consequently i can't proceed with the installation. If i try with a Fedora server distro, then the standard hard drive is detected, the SSD one is still not detected. I do prefer to install

Hi, I have my files and R session on a portable hard drive to be able to work across computers since I have some extremely large files. I have just started doing this and generally it works as I expect. But after a while of using my R session, certain types of calls to open connections on the hard drive don't work. But I experience no problems opening/saving files on the portable hard
