LJ has ads from Polywell every month, I'm pretty sure they have something up your alley. (www.polywell.com/us/lx) You could also use the BeagleBoard, buy a 2-disk SATA hotswap tray, and a chassis, but you can't use a standard distro. You could always rig up to eSATA enclosures to pretty much anything that supports eSATA... Or USB, albeit at lower performance. The two-hotswap-bay requirement will likely have you either using external equipment, or an ordinary ATX mid-tower case... Regular 5.25" bays also get you reasonably cheap hotswap trays. Size-wise, almost no-one bothers making OEM product at the 2-disk level; there's tons of options in 19" units or 8-bay towers. How much are you willing to spend? -Adam

Anyone out there in MUUG-land use R at all (http://www.r-project.org/) or do any sort of data mining? Wouldn't mind talking to you sometime if so. Thanks, Sean -- Sean Walberg <sean(a)ertw.com> http://ertw.com/

Fwd: HotCloud '10 Submission Deadline Approaching
by Gilbert E. Detillieux 18 Mar '10

18 Mar '10

FYI... -------- Original Message -------- Subject: HotCloud '10 Submission Deadline Approaching Date: Thu, 18 Mar 2010 09:16:00 -0700 From: Lionel Garth Jones <lgj(a)usenix.org> We're writing to remind you that submission deadline for the 2nd USENIX Workshop on Hot Topics in Cloud Computing (HotCloud '10) program committee is approaching. Please submit your work by Tuesday, March 23, 2010. http://www.usenix.org/hotcloud10/cfpb Cloud computing has attracted a great deal of attention both from the research community and from industry. The cloud computing paradigm has evolved over the years from a basic IT infrastructure (data centers) to platform as a service (PaaS), and then from software as a service (SaaS) to complete service enablement on a hosted infrastructure (IaaS). At the same time, virtualization has emerged as a key enabler for the cloud computing paradigm. Several challenges arise in the design, implementation, and deployment of virtualized clouds. HotCloud will provide a forum for academics as well as practitioners in the field to share their experience, leverage each other's perspectives, and identifynew/emerging "hot" trends in this area. Topics of interest include but are not limited to the following: * Platform as a service * Software as a service * Infrastructure as a service * Elasticity and availability in a cloud * Multi-tenancy * Storage cloud * Charging models and economics * Power-efficient ("green") computing for clouds * Virtual appliance management and composition * Monitoring, troubleshooting, and failure recovery * Cloud management and configuration * Programming models * Security and privacy in clouds * New applications for clouds * Mobile clouds * Cloud usage scenarios For more details on the submission process, please see the complete Call for Papers at: http://www.usenix.org/hotcloud10/cfpb We look forward to receiving your submissions!

My MySQL battle
by Raymond J. Henry 16 Mar '10

16 Mar '10

OK, I've come to the conclusion that I'm doing something wrong, but can't for the life of me figure out what it is. Going over and over and over documentation, I must be interpreting something wrong, because I think I'm doing what it says. I'm setting up a new box with CentOS. Installed MySQL, and it's running. Now I get to setting the password. Here's the issue. I start with: mysqladmin -u root password SQLROOTPASSWD. No problem Then I try: mysqladmin -h myserver.mydomain.com -u root password SQLROOTPASSWD. This is where things go South. I get the response mysqladmin: connect to server at '(my server)' failed "Access denied for user 'root'@'192.168.1.160' (using password: NO)' I'm at a loss. Hours of fighting with this, and I'm nowhere... Help?

NAS box
by Montana Quiring 16 Mar '10

16 Mar '10

Hello, Looking for a recommendation of a NAS box that I can install my own Linux distro on. (i.e. not a proprietary firmware based NAS). I'll probably install either CentOS or UbuntuServer on it. I would like it to have two or three hot swap bays. It doesn't have to be an all-in-one solution, even just a decent case/MoBo combo you have used would be fine. Does that make sense? -Montana Blog and Aggregation Site: http://montanaquiring.info iPhone/Touch Apps I have bought: http://appshopper.com/feed/user/antikx/myapps

SheevaPlug
by Brock Wolfe 15 Mar '10

15 Mar '10

Unfortunately I wasn't able to attend this meeting. Were there any web links or on-line presentations made available? March 9, 2010: Marvell SheevaPlug This month, Kevin McGregor presented a "show and tell" of the Marvell SheevaPlug, a Linux-based computer which fits in a power adapter. With a 1.2 GHz ARM CPU, RAM, flash memory, gigabit Ethernet, USB and more, all at under 7 watts, this small device has enormous possibilities! Kevin talked about his particular experience with the SheevaPlug and his planned use for it. Thanks Brock

Re: [RndTbl] firewall/router in a VM

<soapbox> That's because we don't, collectively, think about hardware. And we don't think about hardware being buggy. And we especially don't think about "hardware" having inherent security flaws. (OK, yes, the security folks who crossed over *into* IT do. They aren't auditors, for better or worse.) A Cisco router is "software" enough (and has had enough bugs :-) that it crosses into our conscious awareness regarding security, but their switches? Nah. Mature product, all hardware (despite running an OS), no bugs. Either works or it doesn't. Bullshit. Show me a hardware-accelerated device and I can show you half a dozen ways it could fail unnoticed, (potentially) compromising security as it goes. Notice that we install local firewalls on every PC but don't use ECC memory to guard against random bit errors. (I do, BTW - even on my PC. It's one small part of why I don't have a laptop.) A HERF gun is a better DoS tool than any virus or worm, by several objective measurements. The entire IT industry has its head stuck up... you know where, in so many different ways. Yet, this isn't surprising. Humans want instant gratification, a free ride, and the illusion of control. Those things are all way easier with software than with hardware. (Contemplate the difference between "soft" and "hard", if you will, for a moment.) Do I expect this to change any time before the heat death of the universe? No. But I sure wish auditors took a wider view of the world.

RAID controller trouble
by Robert Dyck 15 Mar '10

15 Mar '10

I have a client having trouble with her RAID controller. She reports that she keeps getting an error on boot that her raid set is out of synchronization. It takes close to an hour just to boot when this happens. When I've looked at it the problem did not occur, but this can happen with intermittent problems. I ran hard drive diagnostics, CPU, motherboard, RAM, and everything works fine. I have a hard drive controller diagnostic from Seagate, but it isn't designed for RAID. Her motherboard is an Asus K8V, I think it's K8V-MX, she has 2 SATA hard drives mirrored, and she runs Windows XP. I have mentioned that she may have to replace her motherboard, but I don't want to tell her she has to do this unless I can confirm it is necessary. If she replaced the motherboard and the problem continues, I would hear about it! Thanks, Rob Dyck
