From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially. This patch is developed and on top of the send/receive btrfs and btrfs-progs repo at git://github.com/ablock84/linux-btrfs.git (send-v2) git://github.com/ablock84/btrfs-progs.git (send-v2)

"btrfs subvolume list" gets a new option "--fields=..." which allows to specify which pieces of information about subvolumes shall be printed. This is necessary because this commit also adds all the so far missing items from the root_item like the received UUID, all generation values and all time values. The parameters to the "--fields" option is a list of items to

Hi, I'm using the rsept for WINDOWS 95 (with modified men?, and "fixed" survival4).

Dear All, I have a pair of .cpp and .def file can be compiled using VC++ and works perfectly well in S-PLUS. I wanted to do the same for R; so I followed the guidline given in "Building from a source-code library under Windows" as much as possible and manage to compile them using VC++ and call it from R. But it gives different answer from the one called from S-Plus. I know that I did

Are there any packages that do non-linear integer otimization? Looked at lpSolve but i'm pretty sure it only works with linear programming and not non-linear, tried "L-BFGS-B" optim after flooring all my params, works somewhat but seems really inefficient. Anything else I should look at? -- View this message in context: http://r.789695.n4.nab...

What's up fellows... I am a begginer in R and i am trying to find the parameters of one likelihood function, but when i otimize it, always appers a error or advertisement and the solve does not occur. The problem seems like that: "lMix<-function(pars,y){ beta1<-pars[1] beta2<-pars[2] beta3<-pars[3] beta4<-pars[4] beta5<-pars[5] alfa1<-pars[6]

I am using R 2.7.0 on a linux platform. I am trying to reproduce a 2002 example using lme from the nlme library. I want to change the otimizer from the default (nlminb) to optim. Specifically, this is what I am trying to do: R> library(nlme) R> library(car) # for data only R> data(Blackmoor) # from car R> Blackmoor$log.exercise <- log(Blackmoor$exercise + 5/60, 2) R>

...mpiled and it worked great. I executed accidentally the ls -l command in directory where was the source and executable, I noted and was surprised that because the executable size was to further 20 times more than source. I executed the gcc -Os source.c -o executable.agi command several times, with otimization flags different. Maximum i can affort to reduce the executable size was 17 times. The source size full comment is 448 Bytes; The size executable was about 7615 Bytes. (the maximum i got to reduce) I was hope the executable size was in the order of magnitude of the proper source size, since the co...

Hi, I did replace an old asterisk box by a new shiny one (2 BRI ports used on a quad port card - BeroNet PCI Express) I noticed a message in the logs that puzzles me: May 11 19:10:02 kernel: dahdi: Master changed to B4/0/1 May 11 19:10:08 kernel: wcb4xxp 0000:05:04.0: PCI INT A disabled May 11 19:10:08 kernel: wcb4xxp 0000:05:04.0: Driver unloaded.

Hello, This patch adds rollback support for the converter, the converter can roll back a conversion if the image file haven't been modified. In addition, I rearrange some codes in convert.c and add a few comments.

I have a 1.5 TB (1,475,720,773,632) partition that I wanted to convert from ext4 to btrfs. It is currently used as / for ubuntu 10.10. I booted into 11.04 beta2 and tried a ''btrfs-convert /dev/sdc1'', but after about 20 minutes it segfaulted. I performed a: sck.ext4 -cDfty -C 0 /dev/sdc1 After everything was clean, I downloaded the debugging symbols for btrfs-convert and

A previous issue has popped up and once again I'm out of ideas. During the evenings it seems that the TDM channels will spike (dahdi_monitor) and will refuse to listen for audio of any type, this includes DTMF. The only resolution I know of is to stop Asterisk and restart the dahdi service, but that's not a solution. All channels look like this, even the FXS. [root at asterisk Hardware]#

We want ''btrfs subvolume list'' only to list readonly subvolumes, this patch set introduces a new option ''r'' to implement it. You can use the command like that: btrfs subvolume list -r <mnt> Changelog v2 -> v3: - re-implement list_subvols() - re-implement this read-only subvolume list function based on the new list_subvols() Changelog v1 -> v2: -

From: Anand Jain <anand.jain@oracle.com> (This patch is for the review/test not yet for the integration). Here is an implementation of the feature to add label to the subvolume and snapshots. Which would help sysadmin to better manager the subvol and snapshots. This can be done in two ways, one - using attr which is user land only changes but drawback is able to change the label
