I've been Linux user for over 10 years, and been computing since around age 11. I got my start in programming by learning Perl on my Debian machine in high school. Since then I've learned numerous languages including C, C++, and Python. I've also dabbled in Java and assembly.

I have a bachelors degree in Computer Engineering from Simon Fraser University in Burnaby, BC, Canada.

I've worked in Japan as a CAD software developer in C++ on Windows. Not my favorite environment, but an interesting project never the less.

I'm currently employed by a Vancouver-based biotech startup working primarily on systems level projects but doing my fair share of software development.

My favorite programming language is Python and I use it nearly every day. My recent interests lie in virtualization, hpc, and large-scale systems management. I'm an active contributor to the Bcfg2 project.

comment raid 5 rebuilding epic fail
Ouch. This is (one reason) why having one 20 drive array is a bad idea! At least stripe between a couple of arrays. It's just not worth the extra space savings.

comment “Brain dead”ing APC UPSes: likely to be helpful?
I'm surprised. APC has always RMA'd stuff for me real quick, or sent replacement parts for things damaged in transit.

Added some clarification regarding the traversal.

I posted a similar question here: serverfault.com/questions/38756/… but never really got a satisfactory answer.

This doesn't really have much to do with system administration...

comment can't figure out why apache LDAP auth fails
Funny enough, I had one Apache 2 server that authenticated against LDAP which was working fine for months, then just last week started exhibiting this exact same problem! I can't for the life of me figure out what it is, I've tried all sorts of things. Going to watch this question.

comment Distributed, Parallel, Fault-tolerant File System
GlusterFS is a client-driven architecture. That means in a replication scenario it's typically the responsibility of the client to write the data to both locations. That means if you wanted to replicate between two clusters of data, you'd pretty much have to define another layer in your filesystem and have your clients write to both. Another possibility is that the storage servers are themselves GlusterFS clients of another cluster, and they write the data which is written to them somewhere else, but that's getting complicated.

comment Install YAST package under Ubuntu
As a long time SUSE user, this is the first time I've heard of .ypm files. Do you have an example of one somewhere?

comment How Can I Automate the Backup of a Quickbooks Server?
One copy every 4 hours, retained for a day, another copy every night retained for a week, and a copy every week retained for 4 weeks.

comment How can I configure Apache to redirect a subdirectory to a subversion repo?
That would work if he were still running a second server. It looks like he wants to move the repository to the new server and just not change the URL.

comment Assign DHCP IPs for specific MAC prefixes
Syntax is substring(string, offset, length), so it should be (1, 8) I think... man 5 dhcp-eval isn't clear on this.

I prefer the /1, it's more explicit.

comment include/exclude files for “scp -r”
This is definitely the best way to do it. rsync also uses SSH as a transport, so is more or less equivalent to using scp.

This is a subjective question and should be a community wiki.

This works, but is the ghetto way to do it. The other answers are better, IMO

We do exactly this for DMZ hosts.

comment How can I tell if irqbalance is doing anything?
I think the page says it all: "To a large degree, the work irqbalance does is invisible to you; if irqbalance performs its job right, nobody will ever notice it's there or want to turn it off." :P

A clever workaround. I'll have to keep that one in mind.

comment Unmount a nfs mount where the nfs server has disappeared
Not necessarily. automount mounts can also hang in this condition, if you try to access the directory in any way the process will hang.

Thanks for explaining it a little more succinctly. I forgot about the vdev limitation.
