comment r8168 connection drops randomly
this seems like a hardware problem of some sort, either with the cable or the ethernet interface itself. It's not unheard of for on-board ethernet interfaces to fail. You might have to get a USB ethernet interface and use that instead.

comment r8168 connection drops randomly
now I have a new theory. Check the IP address of the ethernet interface while it works. After it quits working, check again. Maybe dhclient or dhcpcd is giving up on the lease or getting a bad lease or something. You should also try ethtool and/or mii-tool while it works, and after it quits working. Some difference in output might clue you in.

comment How to kill a task that cannot be killed (uninterruptable?)
How about adding the output of ps -l -p 31207 to see what the "WCHAN" column holds. Beyond that, the question you reference has the answer: if you can't kill a process, it's waiting on network filesystem, there;s a kernel bug, or there's a hardware problem.

comment r8168 connection drops randomly
This is odd, but it seems to me that you might have a bad cable, a cable with an intermittent short or something. Can you try this with another cable?

comment How can I count the number of whitespace characters in a file?
@Alison - your method might seem indirect, but I don't think that's the case. No matter how you do this task, you have to have a program that examines every character (every byte) in the file. There's no short cuts for that I can see. "Deleting" isn't really the case, as tr actually just passes all whitespace characters down the pipe. It's just selective about what characters it passes, rather than "deleting" anything.

comment Can tarring files improve compression?
The "random" file contents are a problem. They're incompressible. Use two different large text files to get a better idea. A related idea here is "normalized compression difference". You might take a look at ims.cuhk.edu.hk/~cis/2005.4/01.pdf to see what kind of problems you can encounter doing this kind of testing.

revised How to check if NTPD updates machine's time successfully using shell?
Change a wrong edit (MILLIseconds) back to seconds: ntpdc uses seconds, ntpq outputs in msec. Look at a man page before editing, folks.

comment Wifi cuts out after some time
In addition to the Wi-fi chipsets of both laptop and router, you should mention the age of both laptop and router. I've read people speculating that "low noise amplifiers" wear out when they age. I've certainly experienced the symptoms you describe, but all of my gear is either used to hand-me-downs, so I never experienced it new.

comment Extract just the hostname and port number from tnsnames.ora file
There may not be a good way to reliably get the Service Identifier without a full parse of the descriptions. I don't see a good way to shortcut a grammar-based solution. The only reason my awk-based solution to finding the "HOST" value works is that I could make name/value pairs out of the descriptions.

comment Kernel driver for wireless adapter not in use
@TheDerkus - I've never set up or used a dual boot machine, and I only use Windows at work. I would guess that you could mount the Windows disk when you've booted from a USB drive, but I don't know for sure. That's really another question.
