Here is what I see in MacOS Activity Monitor, note %CPU column.
First item (Xcode process) shows 122.4 value. Any idea what it represents? If it is 122.4% then percent of what exactly?
The %Cpu usually represents the % usage of a single core on your processor. If you have a quad-core, you have a total usage possibility of 400%.
Your first process in your list has 28 threads spread accross more than one core which are using more execution than a full single core.

I see the following ps output. What does U<s mean? How to force it running?
root 3531 0.0 0.4 4737660 34172 ?? U<s Wed09AM 189:36.15 /System/Library/CoreServices/backupd.bundle/Contents/Resources/backupd
U is uninterruptible wait
< is high priority
s is session leader
The last 2 are in common with other systems; I've never seen U before (uninterruptible wait is usually 'D' since disk I/O is a common case).
It can't be "forced" to run except by completion of whatever it's waiting for, which is not apparent from just the state.
How do you know it's not running? I imagine that a backup process is I/O bound so it will quite likely be in an I/O wait when you look at it - but that doesn't mean it's been waiting all alone; it could be flipping between waiting and running quite rapidly.

I am trying to create a paragraph style for number lists. Pretty basic, just some customized indents etc. But each item in my list is not sequentially numbered, i.e., each item starts with 1.
Please advise.
Have you looked at "Numbering style" option ?
In my french version, "Suite…" means increment previous number. And "Commencer…" means "Starts at…"

why conky duplicates the display after every minute as the picture
This looks like a common issue with Conky and graphics. You can try enabling double buffering:
# Use double buffering (reduces flicker, may not work for everyone)
double_buffer yes
or fiddling around with the own_window, own_window_type, and own_window_transparent settings.
I solved the problem by own_window_type normal
in the file ~/.conky

my computer has ubuntu 14 installed. There are a total of 40 CPUs, and 260G memory.
I use top command line to check the status of the processes. I was expecting that for each individual process, the virt value should be approximately equal to 260 * mem%. However, it is not.
Could you anyone help me to figure out why?
Thanks for any input:))
The MEM% column shows the amount of physical memory that is being used by a process. This amount is called the "Resident Set Size" (RSS) and is given in the RES column. The amount of virtual memory on a system is effectively unlimited due to the fact that each process has their own LDT (on x86; other architectures' MMUs have their own equivalents).

I am trying to get bandwidth value of Wan interface in Open-Wrt router (WRT54GL) using
OID: 1.3.6.1.2.1.2.2.1.10.4
But I keep getting value around 4174517174
I was doing some calculations and it does not make any sense:
4174517174 / 8 / 1024 /1024 = 497 MB/s
Does this value contains more info like time or something or my OID is incorrect ?
I have got the answer. Its the whole traffic which has passed trow this interface. To get the bandwidth you need to get the difference between two past values...
