how to calculate growth rate of CO2 (ppm) time series
Dear R Users, I have CO2 mixing ratio(ppm) time series data during 1991-2000. I would like to calculate CO2 growth rate /ppm.a-1 (is it derivative dt/dco2 ??) Kindly can any one advise how to calculate above. My data file looks like; time, year, month, day, hour, min, sec, lat, long, height, CO2 1991.476722 1991 6 24 0 5 0 -38.93 145.15 4270 353.680 1991.476741 1991 6 24 0 15 0 -39.20 145.22

Question on weird output from a Compaq R3000
Hi All, I put my Compaq R3000 UPS on NUT. Every once in a while the battery alarm light turns on, on the front of the UPS. Maybe once every couple of days or so. When that happens I get the following output in /var/log/messages: Sep 22 01:51:46 mail upscode2[90734]: Unknown response to UPDS: .20 MOUL1 Sep 22 01:51:46 mail upscode2[90734]: Unknown response to UPDS: 0119.20 MOIL1 Sep 22

[ovirt-users] Re: Gluster problems, cluster performance issues
The profile seems to suggest very high latencies on the brick at ovirt1.nwfiber.com:/gluster/brick1/engine ovirt2.* shows decent numbers. Is everything OK with the brick on ovirt1? Are the bricks of engine volume on both these servers identical in terms of their config? -Krutika On Wed, May 30, 2018 at 3:07 PM, Jim Kusznir <jim at palousetech.com> wrote: > Hi: > > Thank you. I

[ovirt-users] Re: Gluster problems, cluster performance issues
Hi all again: I'm now subscribed to gluster-users as well, so I should get any replies from that side too. At this point, I am seeing acceptable (although slower than I expect) performance much of the time, with periodic massive spikes in latency (occasionally so bad as to cause ovirt to detect a engine bad health status). Often, if I check the logs just then, I'll see those call traces

[ovirt-users] Re: Gluster problems, cluster performance issues
I've been back at it, and still am unable to get more than one of my physical nodes to come online in ovirt, nor am I able to get more than the two gluster volumes (storage domains) to show online within ovirt. In Storage -> Volumes, they all show offline (many with one brick down, which is correct: I have one server off) However, in Storage -> domains, they all show down (although

slowdown in notmuch perf suite with xapian 1.3.5
I hadn't noticed any interactive slowdown, but when I got around to running the notmuch performance suite, there seems to be some noticable slowdown with the glass backend (default in Xapian 1.3.5) compared to chert (using xapian 1.2.22) These tests are on an older i7 with 12G of RAM and an SSD. I'm reasonable confident they are CPU bound. One curious thing is the increase in system time

Adding Ravi to look into the heal issue. As for the fsync hang and subsequent IO errors, it seems a lot like https://bugzilla.redhat.com/show_bug.cgi?id=1497156 and Paolo Bonzini from qemu had pointed out that this would be fixed by the following commit: commit e72c9a2a67a6400c8ef3d01d4c461dbbbfa0e1f0 Author: Paolo Bonzini <pbonzini at redhat.com> Date: Wed Jun 21 16:35:46 2017

climatological standard deviation
Hello R users, I have a montly time series over a several year period. It's easy to compute a monthly climatology (12 values), Now, I would like to calculate the corresponding standard deviation, ie the 12 values calculated from the january values, february values, etc. What's the best way for such a calculation ?

Unreasonably poor performance of replicated volumes
Guess you went through user lists and tried something like this already http://lists.gluster.org/pipermail/gluster-users/2018-April/033811.html I have a same exact setup and below is as far as it went after months of trail and error. We all have somewhat same setup and same issue with this - you can find same post as yours on the daily basis. On Wed, Apr 11, 2018 at 3:03 PM, Anastasia Belyaeva

Unreasonably poor performance of replicated volumes
Thanks a lot for your reply! You guessed it right though - mailing lists, various blogs, documentation, videos and even source code at this point. Changing some off the options does make performance slightly better, but nothing particularly groundbreaking. So, if I understand you correctly, no one has yet managed to get acceptable performance (relative to underlying hardware capabilities) with
