When I added more entries than would fit vertically in a PXE boot menu (Cobbler's, using menu.c32), I wondered why there wasn't a scroll bar. Finally I realized there was one but it didn't look very different from the existing screen border. I changed the color to increase its visibility. However, it still doesn't give a good visual clue that it IS a scrollbar. Would it be

The system log (/var/log/messages) of a CentOS 7.2 system has frequently-repeated message line pairs like: Jul 18 14:00:01 localhost systemd: Started Session 307 of user root. Jul 18 14:00:01 localhost systemd: Starting Session 307 of user root. where the session number increases each time. Looking around on this, e.g. Red Hat Bugzilla bug 727315, it looks like it's when crond starts a

Moving from CentOS 5 to CentOS 7, discovered that a test in a SysV initscript for whether it is running interactively, instead of at boot time, no longer works. Under CentOS 7 / systemd, is there some way for the initscript to know this?

I've previously used includes in CentOS 4.4 and they worked fine. But in CentOS 5.5, trying to specify a driver disk via an include does not work. If I instead specify it directly, it loads fine. When it fails (because it can't see the disk drive - needs the driver disk to see the hard disk), in Console 2 I can see that /tmp/drvdisk exists and has the line I wrote to it. I see nothing

Setting up bonding in active-backup mode 1 (using ARP monitoring) on a server, it looked OK, but pulling the active link cable didn't actually work, it didn't fail over. Eventually with manual playing around with modprobe, ifconfig, ifenslave, etc., a solution was stumbled upon: enslave the eth1 device before eth0, and all is good. Why this should matter is a puzzle - I could not find

Hi, Lets say this was a dataframe where I had two columns a <- c("<0.1", NA, 0.3, 5, "Nil") b <- c("<0.1", 1, 0.3, 5, "Nil") And I just want to remove the rows from the dataframe where there were NAs in the b column, what is the syntax for doing that?

Always via logical expressions. In this case you can use the logical expression myDF$b != "0" to give you a vector of TRUE/FALSE B. > On Sep 25, 2017, at 8:00 AM, Shane Carey <careyshan at gmail.com> wrote: > > This is super, really helpfull.

Hi, I am wondering how I should interpreate the output of optFederov() in AlgDesign. Specially I want to know what is $D, $A, $Ge and $Dea, which one I can use as an efficiency to say how good the optimal design is. I only know when a orthogonal design comes, $D = 1.

Hi All - I notice that most of the Rails team are using Mac OS X and TextMate for Ruby development. I too am working on Mac OS X and trying TextMate and (shudder?) EMacs. I was wondering about version control. Are folks using Subversion? If so, are they using a graphical client? Which one do they recommend? Yours, Jordan -- Posted via http://www.ruby-forum.com/.

I noticed that a number of my Windows hosts had stopped dialing in, and upon closer inspection I found that Puppet was crashing in Ruby and wevtapi.dll. I can''t find any reference to this in the issue tracker, although I''ve got over a dozen occurrences in my environment, all with the same descriptions as below. I checked to see if the times were similar, in case the server
