comment questions about bash background job
There is another command "stop" which stops a background job. This doesn't kill the job, but it will not continue executing until it is restarted. I wonder what is the difference between "stop" and CTRL+Z?

Sorry I should say CTRL+Z, not CTRL+C. What is the difference between CTRL+Z and stop?

That's part of Bash, which is why I ask here.

Also I wanted to ask how to append output to existing file while still make the job background.

comment What is the difference between typing `emacs-x` and `emacs`?
nothing is output for "alias | grep emacs". for "which emacs-x", "/usr/bin/emacs-x"; for "which emacs", "/usr/bin/emacs". Not know what is the difference between the two from these

comment Configuring a cluster
Our cluster is a linux cluster with Torque and Maui. I am reading tutorials online and find that the compilation is only on the head node, and after submitting the job by qsub, the other nodes are running the executable compiled on the head node. So that is why my questions arise.

comment port forwarding in emule
Thanks harrymc! So in this case when modem is connected to router by cable and laptop connected to router by wireless network, what would be the DMZ computer? Shall I add another DMZ computer?

comment port forwarding in emule
Thanks, techie007. When the emule is not running, giving its ports to PFTportCheck will see message like "your port is not open or not reachable". When the emule is running, PFTportCheck "could not test port xxx because some other application has the port locked." Does this mean the my laptop does not block the ports of emule?

But I am connecting my laptop to a modem without using a router. If it does not work without a router, how can it work with one.

comment File Operation not supported on Windows drives mounted on Ubuntu
Thanks. If I want to mount the drive with read and write, how to do it? By the way, I finally solved this problem, but not sure exactly how. My /windows-d has only about 500M left free. So I delete some files and got 1.2G free. At the same time I updated my system. After reboot, it works again.

comment Hardware Configuration Check on a New Laptop
Thanks John T! Yes it's design capacity is 56.16Wh. (1) do you mean 3 cells in series and another 3 cells in series and then the two groups parallel? (2) how do you calculate 56Wh from 4800mAh and 12.5V? (3) the current remaning capacity is 58.73Wh, does this mean my battery is overchanged?

comment Why am I not seeing all the partitions on my hard drive?
Thanks DaveM. Disk Management has three volumes: Lenovo_Recovery(Q:), SYSTEM_DRV and Windows7_OS(C:). All of three are simple layout, basic type and NTFS. SYSTEM_DRV, which is actually "Partition #0", has status as healthy (SYstem, Active, Primary Partition) and capacity as 1.17GB and 45% free. Lenovo_Recovery(Q:) is also healthy(Primary Partition). Windows7_OS(C:) is healthy (Boot, Page File, Crash Dump, Primary Partition). Although having list some info here, I still don't know what "Partition #0" or SYSTEM_DRV is for.
