What is this dm-0 device?
While poking around trying to figure out why a Linux -> Linux file transfer is running slower than I think it should, I stumbled across something I'm not familiar with. seems to be my bottleneck, but I have no idea what it is. On my destination server, the iostat command shows a device at the bottom, , as being 100% utilized. This server has 6 disks in a mdadm raid5 set, with LVM running on top of it. Each of the underlying disks are sitting around 50% util. The transfer is writing to a logical volume located on this raidset. What is this thing? Once I know what it is, maybe I can find how to increase its speed, or at least understand why its the speed that it is.

How can I take browser screenshots at a higher resolution than my browser supports?
I need to take a screenshot of a website as it would appear on a very high resolution monitor... say 4000x3000 pixels. My laptop's screen has a native resolution of 1400x768. Basically, I need to simulate having a monitor resolution much higher than my monitor and video card actually supports. I want the screenshot of the site to look pretty much how it does when you hit CTRL MINUS (zoom out) in Firefox repeatedly, but without any loss of pixels due to scaling. How can I do this? Is there some way to use virtual machine software to simulate a super-high-res display? If not, is there some way to open a browser window bigger than the screen, and then capture its contents as a PNG somehow? Anything else that might work?
Is there a good tool for monitoring network activity on Mac OS X?
Is there a good bit of software on Mac OS X that I can use to monitor incoming and outgoing network activity? Nothing too geeky, I just want something simple to use. I'm on version 10.6 (Snow Leopard) if that helps.
What is the difference between an Intel i7 and a Xeon quad core processor?
I know the Xeon processors have been around for a long time and are mostly used in servers, but I am curious, why do people not use the Xeons in a high performance desktop? As far as I know about the best desktop processor out there now is the Intel Core i7 line. The i7's and Xeons are both quad-core processors, what is the main difference in these? I just saw that the MacBook Pro's are using the quad core Xeons instead of the i7's.
What commands can I use to reset and clear my terminal?
I have been using the command: to clear my terminal. Although I am pretty sure this is not what I should be doing. Reset, as the name suggests, resets your entire terminal (changes lots of stuff). Here is what I want: I basically want to use the command . However, if you clear and then scroll up you still get tonnes of stuff from before. In general this is not a problem, but I am looking at gross logs that are long and I want to make sure that I am just viewing the most recent one. I know that I could use or something like that but I prefer this approach.
Apostrophes and double quotes don't show up until I type the next letter
in Windows XP, when I type an apostrophe , or dumb/typewriter quote , no character is displayed. If I type another character, the apostrophe or dumb quote and the next character appear at the same time. This happens with double quotes , apostrophes and tilde characters. What could possibly be causing this? This occurs in all applications I have tested - wordpad, firefox, ms word etc.
How can I get the same SSID for multiple access points?
I need to upgrade my existing wireless infrastructure and this time I want 2 access points to cover my house, since I get blind spots no matter what with a single AP. I have physical cabling to my central network available for both access points. I would really like these two to interoperate seamlessly as a single SSID. How do I do this? What are the features that the new access points I'm buying would need to support?

How to know which fonts are used in selected part of a PDF document
I'm using Foxit Reader as default PDF viewer. How can I see what type of font is used for a selected part of a PDF document? (If this can only be done with another software, I'd prefer a freeware as I don't want to pay for just viewing selected fonts' types.)

Why are there many processes listed under the same title in htop?
Can anyone explain to me why there are sometimes 10 or 15 processes with the same title and "stats" listed in htop? I'm guessing there are multiple threads running - but that many of them obviously couldn't be running concurrently. Is there any sort of performance hit taken if a process uses say, 15 non-concurrent threads vs. 10 non-concurrent threads?

How to do networking between virtual machines in VirtualBox?
I have two virtual machines in VirtualBox. I would like to do networking between them. For the moment I have the default configuration on both, but they seem to have the same IP-address . I would also like to be able to use Internet with both, and that is Possible now. By default the network-setting is NAT, but it seems like they cannot network internally since they have the same IP. But If I change to I guess that I cannot access Internet with the virtual machines. How can I set up networking between virtual guest AND have access to Internet on them?
