Datetimes differences
I want to obtain datetime differences in mins in an other column, in front of my
datetimes. I have tried this :
T1 <- c("12/31/03 23:49","1/1/04 1:14","1/1/04 0:02")
T2 <- c("1/1/04 0:58","1/1/04 1:16","")
toto <- data.frame(T1,T2)
toto
y <- strptime(T1,"%m/%d/%y %H:%M")
x <- strptime(T2,"%m/%d/%y

Problems of data processing
I have two problems for the data processing of my large data base (50000 rows). For example, a sample is as follows

/home on BTRFS on SSD, now highly fragmenting virtuoso database - use autodefrag?
Hi!
Today I converted my /home from Ext4 to BTRFS by reformatting and copying
all over again.
I created the filesystem with -l 16384 -n 16384 -d single -m single on an
logical volume Intel SSD 320 and mount with compress=lzo,spacecache. Current state:

fstrim on BTRFS
Hi!
With 3.2-rc4 (probably earlier), Ext4 seems to remember what areas it
trimmed:
merkaba:~> fstrim -v /boot
/boot: 224657408 bytes were trimmed
merkaba:~> fstrim -v /boot
/boot: 0 bytes were trimmed
But BTRFS does not:
merkaba:~> fstrim -v /
/: 4431613952 bytes were trimmed
merkaba:~> fstrim -v /
/: 4341846016 bytes were trimmed
Is it planned to add this feature to BTRFS

I'm trying to perform a RFM analysis on attached dataset,
i'm able to get the results using the auto_rfm function but i want to
define my own breaks for RFM,
when i tried to define my own breaks i got the identical result i.e 111 for
every ID.

New package test results available
We've added a column at
http://cran.r-project.org/web/checks/check_summary.html
of test results using the Sun Studio compiler: it is intended that
these will be updated weekly.
The Sun Studio compiler is that used on Solaris: these runs were on
the Linux version. All the other platforms are using gcc 4, so this
provides an opportunity for checking for use of gcc-specific features

How to define proper breaks in RFM analysis
Hemant's problem is that the indicators are not distributed uniformly.
With a uniform distribution, categorization gives a reasonably optimal
separation of cases. One approach would be to drop categorization and
calculate the overall score as the mean of the standardized indicator
scores. Whether this is an option I do not know. I did offer an
"eyeball" set of breaks in a previous

How to define proper breaks in RFM analysis
hello,
I'm confused what you guys are talking about.
i just want to set ideal threshold values for my RFM scores which can be
done using Quantiles but i don't want to use quantiles because my data is
not normally distributed so it will lead to wrong ranges of breaks. to fix
this problem I'm looking for an approach which can define the ideal range
to breaks to categorize RFM scores into

How does btrfs behave on checksum mismatch?
I came across the tidbit that ZFS has a contract guarantee that the
data read back will either be correct (the checksum computed over the
data read from the disk matches the checksum stored on disk), or you
get an I/O error. Obviously, this greatly reduces the probability that
the data is invalid. (Particularly when taken in combination with the
disk firmware''s own ECC and checksumming.)

Very slow samba file transfer speed... any ideas ?
Hi,
I have btrfs volume, shared via samba.
I have a directory of documents that I want to backup on my server.
win7 reports a maximum of ~3.10MB/s transfer
transferring the same directory on a ext4 samba share I get 25MB/s +
Any ideas?
Is it like that because of how btrfs works and is setup?
Thanks,

[PATCH] Btrfs: don't call readahead hook until we have read the entire eb
Martin Steigerwald reported a BUG_ON() where we were given a bogus bytenr to
map. Turns out he is using > PAGESIZE leafsizes. The readahead stuff is called
every time we do a completion, but we may not have finished reading in all the
pages, so the bytenr we read off the node could be completely bogus. Fix this
by only calling the readahead hook once all pages have been read in. Thanks,

BTRFS, getting darn slower everyday
Hi,
I have 4 machines, all converted to BTRFS about 6 months ago, now all
running Ubuntu Quantal with kernel 3.5.0-17
The matter is that all these machines are now getting slower and slower
everyday, every disk access causing the disk to be 100% busy for long
periods, to the point that I''m now seriously considering migrating
everything back to ext4...

How to define proper breaks in RFM analysis
Hello,
I'm working on RFM analysis and i wanted to define my own breaks but my
frequency distribution is not normally distributed so when I'm using
quartile its not giving the optimal results.
so I'm looking for a better approach where i can define breaks dynamically
because after visualization i can do it easily but i want to apply this

[RFC] New attempt to a better "btrfs fi df"
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi all,
this is a new attempt to improve the output of the command "btrfs fi df".
The previous attempt received a good reception. However there was no a
general consensus about the wording.
Moreover I still didn''t understand how btrfs was using the disks.
A my first attempt was to develop a new command which shows how the
disks
