• Is it possible to "virtualize" an existing PC?

  - by pnongrata

  I'm running Ubuntu Desktop 12.04, and I was wondering if it was possible to somehow take my whole filesystem (everything under /) and create an ISO from it. Then, perhaps, use that ISO as the file system of a VBox VM (obviously, it would have to be Ubuntu, and probably 12.04). Basically, I've spent a lot of time configuring my development machine, but need to be able to work on it from whatever computer I happen to be at. VMs seem like the perfect solution. Thanks in advance!

• How big are most production databases?

  - by TheLQ

  Seeing some posts that say 10 million rows in a table is nothing made me wonder: Just how big are most production databases? I'm not talking about physical disk size of the database (saying 60 GB tells me nothing), I'm wondering how many rows. Personally the largest DB I've ever worked with was a test DB of a production system with 10 million rows. But I've seen people brag about DB's in the billions of rows.

• Two network cards latency

  - by Ross W

  I'm trying to setup a network architecture where one network is a low-latency low-bandwidth tcp control system (GBit), the other is a high-bandwidth udp (maybe tcp) network that could get saturated (GBit). If I have two NICs inside a server running Linux. What happens to the low-bandwidth/low-latency network when the high-bandwidth gets saturated. Does each Ethernet card get the same amount of priority inside the kernel or would the low-latency network suffer from the high-bandwidth being saturated?

• What are your favorite open source tools? (that are not very famous)

  - by sucuri

  I believe every system administrator is used to open source by now. From Apache to Firefox or Linux, everyone uses it at least a little bit. However, most open source developers are not good in marketing, so I know that there are hundreds of very good tools out there that very few people know. To fill this gap, share your favorite open source tool that you use in your day-to-day work that is not very famous. *I will post mine in the comments.

• Have optical drive connectors changed in the last year?

  - by Zippityboomba

  In early 2010 my motherboard freaked out, and I was able to drop in a new board and connect my two DVD drives that were initially bought in 2005. Tonight my new components arrived to build my next system, and I figured I'd just reuse the old DVD drives. Surprise, the long flat connector cable has no mate on the new motherboard. Reckon I'll just pick up a new DVD drive for $25, but what gives? Thanks!

• virutal users in postfix

  - by facha

  Hello everyone, I'd like to setup postfix as an MTA for 2 domains, about 10 users each. I'm a bit confused with the documentation. Postfix has so many options for mail delivery. I'd like to have a simple file where I would store all the email addresses (and possibly their corresponding mailboxes). I wouldn't like neither system's passswd file nor mysql to be used for storing email users. What parts of documentation I should be focused on?

• How do I change the space I allocated to my virtual hard drive in VirtualBox?

  - by Guest

  Hi, I have a Win7 x64 virtual machine running inside VirtualBox. When I first setup the system I gave the virtual hard drive 20gb of space to work with, but I also set it to dynamically expand (or so I thought). Unfortunately I ran out of space and the drive is not expanding/changing.. and I can't find a way to alter the size of it. Is there anything I can do in this situation. Thanks in advance.

• Can a hard poweroff / outage / crash corrupt VMware snapshots?

  - by basic6

  Assuming a host system is running virtual machines (in VMware Workstation) and all their data is on a reliable storage (so no data corruption due to hdd failure). If that host crashes (kernel panic) while a vm is running, files on the virtual filesystem could be corrupted. But there's a snapshot (of the vm), taken before the crash. Is it safe to assume that reverting to the snapshot, the vm will be back in a clean state - or is there any way that this snapshot could have been corrupted by the crash?

• How many Tomcat instances can one application server handle?

  - by NetworkUser

  My network engineer states I am part of a cluster where two apache application servers(512G RAM each) have 142 instances each of Tomcat (of which my company represents 6 each with 2G RAM). This seems like a lot and my latency issues move with the hour of the day - 7AM CST software functions fine, 10AM CST - system slows significantly this slowness continues until 6PM CST. My question is how many Tomcat instances can one application server handle?
