Novel is long gone from the picture. Presently Mono is a Ximian project (http://www.mono-project.com) which is where it started as far as I can recall. To the best of my knowledge Moonlight recently was resuscitated after having near death experience but, at the moment, is SUSE only as far as Linux support goes. -- *** E-Mail is NOT a SECURE channel *** James B.

Centos-compatible motherboards
by Fred Smith 11 Feb '14

11 Feb '14

Hi all! I'm toying with the idea of spending some Christmas money on a new MB and CPU to upgrade my desktop. Although I've always been partial to AMD chips, I'm tempted this time to find something Intel-ish, I5, quad core, or so. In looking at mommyboards at New Egg and Amazon, I find so many I am unable to make reasonable determinations regarding suitability, so am hoping some of you who have new(ish) intel-compatible boards could offer some hints. Also, I'd like to keep the cost of MB, CPU and RAM to no more (or little more) than $300-350. (seeing as how apparently mid-range I5 chips cost over 200 each, that may be a vain hope.) I expect that the newest ones may work with something bleeding edge like Fedora (et al), but I like centos for my desktop since it doesn't have the ridiculous churn rate of the more aggressive distros. I can't bring myself to relish the thought of rebuilding my main desktop twice a year (or even once a year). So, any suggestions will be greatly appreciated! Thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- The Lord detests the way of the wicked but he loves those who pursue righteousness. ----------------------------- Proverbs 15:9 (niv) -----------------------------

Multitab GUI SSH clilent found
by Ljubomir Ljubojevic 08 Feb '14

08 Feb '14

Hi. I just wanted to notify all that I found very nice GUI SSH client at http://sourceforge.net/projects/pacmanager/ It has rpm packages and works very nice. Multi-tab, Expact support, connections tree, connection , user and password saving (I know they should not be saved). Only manual download as far as I know, no repository caries it. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe StarOS, Mikrotik and CentOS/RHEL/Linux consultant

died again
by Michael Hennebry 04 Feb '14

04 Feb '14

CentOS 6.4 died on me again. Didn't leave any traces that I could find. The screen just suddenly went black. Couldn't switch to another virtual terminal. Pushing the reset button worked. Didn't have to power off this time. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "On Monday, I'm gonna have to tell my kindergarten class, whom I teach not to run with scissors, that my fiance ran me through with a broadsword." -- Lily

I want to ask about some Kernel level operations.
by Eliezer Croitoru 04 Feb '14

04 Feb '14

I want to make sure that while compiling as root nothing will break down inside the machine. I want to compile software on a Xeon SERVER. The basic issue is that there is a recommendation to not compile it as a root user. I have compiled software as a root user more then once and I am not sure why would there is a need to run it as non-root user? I have taken a look at the /proc/ FS but I do not see anything that can harm anything yet. From my aspect it's just background of electricity noise. I will be happy to hear from experience of others about it. Thanks, Eliezer

CentOS Tshirt ideas
by Karanbir Singh 01 Feb '14

01 Feb '14

hi, We have, like in the years past, a table at Fosdem and I'd like to get some tshirts printed to hand out. In the past, the Linux Ninja's and Beards ones got quite a bit of attention ( and both were not brand spammy, which is always nice ). Reaching out to the mailing list for ideas on what we can do this year, with the caveat that I need to finalise by this weekend if we are to get anything in by Fosdem. thanks in advance, -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

OT hardware question
by m.roth＠5-cent.us 01 Feb '14

01 Feb '14

With the continuing annoyance from motion, my manager's asked me to go looking again for a video surveillance appliance: basically, a motion-detecting DVR and cameras. The big thing, of course, is a) price (this is a US federal gov't agency, and being civilian, money is *tight*, don't give me the libertarian/GOP line about how freely we spend, thankyouverymuch), b) it has to be on the network, and c) we need to be able to d/l to a server, and rm after we do that... and we want to script or cron job that. Right now, I'm looking into Zmodo, R-Tech and CIB security. Anyone have a) opinions on the quality of the hardware from any of those manufacturers (yeah, I know, they're just branded hardware), and/or whether we can do the ssh or telnet in to do what we need? *Extremely* frustrating, since they're all running embedded Linux, that so many say IE and Active X.... mark

Are VMAC drivers stable?
by Jan Hugo Prins 31 Jan '14

31 Jan '14

Hi, I'm currently looking into the VMAC options that Keepalived had to offer. This all looks very nice, but now I heard that the VMAC driver in the linux kernel is not really stable if you are not on a 3.2 kernel or later. Can anyone here tell me some more about this? Is this really true? Should I wait with the VMAC options until Centos / RHEL are on a 3.2 kernel? Jan Hugo Prins

Recent version of Latex
by Patrick Begou 31 Jan '14

31 Jan '14

I've moved most of my user's PCs from OpenSuse (11.x, unmaintainend now) to CentOS 6.4. On my old OpenSuse latex was "texlive-latex-2010" and current version on CTAN is texlive-2013. But on CentOS 6.4 I've only the old texlive-latex-2007 and several sty files available on my previous config are not available now and users cannot compile their previous documents. Is there a Yum repo from where I can install a more uptodate latex environment for CentOS6.4 ?
