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 Linux LVM: Single or Multiple Harddisk Partitions?
Agreed with MikeyB. Many tools will detect the disk as being unpartitioned and you can happily blow it away without realizing it.

comment configure apache for SVN SSL
That's probably because the checkout you have still points to the old http:// address. You need to use svn switch --relocate on your working copy to update the address.

comment Providing access to a Samba server for VPN clients
If only it were that easy. They're actually on Mac laptops and run Windows in a Parallels Desktop instance on their laptop. I originally thought about putting all the Windows instances on a central server that people would remote desktop in to, but the idea wasn't well received for some reason.

comment FreeBSD RAID rebuild by data center, now data in /var/logs and /var/db/mysql is *gone*, OH NO!
Now would be a good time to think about setting up some backups.

Are you using NAT networking in VirtualBox, or bridged mode?

comment Two identically configured sendmails, one of them is not delivering mail
I checked these and they're empty on both boxes. I thought that by virtue of mail.example.com being the MX record for example.com, they should both be able to figure out that systems@example.com should send there. Indeed it seems like gw003 does. Or am I wrong in this assumption?

comment Two identically configured sendmails, one of them is not delivering mail
I've checked the relevant IP addresses (the primary management interface IP, the interface for the VLAN with the mail server, and the primary external interface) and the forward and reverse queries seem to match. hostname shows the FQDN for both systems, and it is set correctly in /etc/hosts

comment Two identically configured sendmails, one of them is not delivering mail
The successful one also has the same relay line. Also, why would only the second machine think it is the final destination for the domain while the first does not? It seems gw004 decides right away that systems@example.com is an unknown user where as gw003 correctly relays the mail to the mail server.

comment Two identically configured sendmails, one of them is not delivering mail
Sure, apart from the hostname and individual IP addresses. They are a mirror image of each other built with the same configuration managed steps.

comment How do I time synchronize servers without using an external NTP server?
You can use the fudge parameter in ntp.conf to fudge the stratum number.

comment Single Sign On (SSO) with Xgrid, without OS X Server (10.6.x)?
If you already have AD integration, you should already have Kerberos in place, so I don't see the problem there? Also, if you have several small labs, are they all connected to a central domain, or independent? In any case, for the Linux scenario you can just run OpenLDAP and the MIT Kerberos distribution and you should be fine there as well.

comment Is there a way to do something like LVM over NFS?
I don't think that's easily doable with NFS or UnionFS alone. GlusterFS lets you do something like this. It should even be possible to run the GlusterFS server and client on the same machine, and use each NFS volume as a GlusterFS "brick". Then use the distribute GlusterFS connector to, well, distribute your files among the bricks.

smart is on a per-disk basis.

comment VLAN across switches with teamed NIC ports
Yes. Seems like you don't understand the difference between VLAN tagging and just assigning a port to a VLAN. VLAN tagging allows a port to be assigned to multiple VLANs. It does this using the 802.1Q protocol which inserts an additional field in to the ethernet frame between the MAC and EtherType fields. The catch is that your device needs to be configured to looks for this field. Usually this means creating a special VLAN interface on your server which is a child of the physical interface connected to that port.

comment Managing physical installation media storage?
Works especially well for OS's that can mount ISO's just as well as CD-ROMs (Linux, Mac), but I imagine you can just easily install some CD-ROM emulator software for Windows.

comment ZFS server hardware questions
A lot of simpler bonding schemes work on the basis of hashing source MAC addresses. In the case of communication between two machines, you'll have no benefit. heavypix: I'd be glad to tell you more about my setup, but this is probably not the forum to discuss the photo related bits. There is contact info on my website. In short, I use Lightroom with a local catalog backed up to the file server every run, and all the image files are stored there.

comment What can happen when the home network of a VPN Client exists in the VPN Destination Network?
I've also seen some home routers that use 10.0.0/24 or 10.1.0/24 by default. That's one reason we set up our office network to use 10.2.x.x and onward.

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.
