Sysstat -> Graph?
by Adam Keck Aug. 20, 2007

Aug. 20, 2007

Hello All, What are your favorite sysstat graphing tools? I run sysstat on almost everything, but also have orca for Linux collecting data from several servers for graphing. I am wondering if I can make do with only sysstat. -Adam

Awesome article about Windows v. Linux in the marketplace
by Eric Martin Aug. 17, 2007

Aug. 17, 2007

I found this on either digg or slashdot. It's a really good article and I agree with most of it. People won't even consider GNU/Linux while they can still get a copy of XP for free from a buddy. That's why I tell people that I won't support their pirating of software; and pitch FOSS at every turn to them. http://tlug.jp/articles/Windows_Is_Free Give it a read, it might spur some good conversations tonight.

Linux meta-questions - platform choice
by Adam Keck Aug. 10, 2007

Aug. 10, 2007

Hello All, I have some "meta-Linux" questions regarding platform choice. I am wondering if anyone knows of any research, papers, or other work that has been done on the topic. Given two major types of IT infrastructure: - Heterogeneous, where each application/service uses the platform to which it is best suited. - Homogeneous, where one bends a particular platform to fit every edge case. where the platform can be anything from and OS to a language to an application stack. o Under what general conditions is one infrastructure type more efficient than the other? o What other types of infrastructure are there? o More generally, how does one compare infrastructures in a rigorous manner? - How does one rigorously define "efficient" when comparing concepts like infrastructures? - What other metrics, besides "efficiency" (however defined) may be useful in comparing infrastructures? Does anyone know of any work where this topic has been abstracted and analyzed mathematically? Or of any trade papers where this question has been looked at in practice? So far, I found the following paper via Google: http://uic.edu/cba/cba-depts/ids/IDSNewsFiles/JGITM_Evaristopaper.pdf that seems to be on the topic and some hits on arxiv that appear related but not specifically on the topic. This relates to Linux in that convincing an organization to switch entirely over to Linux seems to be prohibitively hard in practice, but if one can show that the heterogeneous case above can be more efficient, then one can make the case for using Linux where it fits best. Thanks for any info/opinions/personal experiences! -Adam

Anybody want a really cheap computer?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, Check this link: http://www.dataevolution.com/dectop%20info%202.htm This company bought the assets to the AMD PIC (personal internet computer).

It was intended for the same market that OLPC is now aiming for. Hence the rugged "big mac" case. :) Of course it lacks a monitor. A few others to consider, Nicer form factor, but slower CPU (166MHz), no HD: http://linuxdevices.com/news/NS6828123924.html http://www.norhtec.com/products/mcjr/index.html USB 2.0, but pricier (price listed in Euros): http://www.linutop.com/ Consumer variant of OLPC XO1, whenever it comes out. http://en.wikipedia.org/wiki/ASUS_Eee_PC Not to discourage you - the PIC looks like a fun little box! -Jamie

core 2 duo extremely slow
by brad Aug. 3, 2007

Aug. 3, 2007

Hi All, I recently got in a nice new 2.4GHz core 2 duo with a bunch of memory, 8GB. I installed kubuntu i386 on it. To get use of the 8GB of memory i recompiled the kernel to enable high memory support, a.k.a PAE. When i booted the new kernel it saw all my memory, but it took 10-15 minutes to boot. i checked dmesg and it didn't seem to report anything out of the ordinary. Then, I thought that perhaps the 64bit version of kubuntu might be a better option. I installed kubuntu 64bit. The install took two days because every step was extremely slow. Once the install finished, i rebooted and it took 10-15 to boot. I was seeing the same symptoms of the 64bit install as i was with the 32bit install with PAE. I tried downloading the current kubuntu 64bit release as well as the beta of the next release. I'm also trying Fedora Core 7 64bit as i type, but that install is going just as slow. I hunted through the BIOS for any suspicious settings. I removed all the hardware except for the CD-ROM (to boot a live CD). I did searching through the interweb. All with no luck to solving this problem. If anyone has any suggestions, they will be much appreciated. keep cool, - brad

Detecting power failure
by Tal Cohen Aug. 3, 2007

Aug. 3, 2007

Hi Guys, I have a question about detecting power failures in Linux. I have an Intel server sitting in a datacenter. It is running Crux 2.1 (a 2.6 kernel). It is a 2U server with 2 power supplies. Does anyone know if I can detect when 1 of the power supplies fails? Thanks, Tal
