I am a curious person who always likes to learn more. I like solving puzzles and I like working with computers. Which means I enjoy some of the more complex questions on this site, as well as the answers which go into details and explain all facets.

comment 'tail' command not getting only the new lines
Does nano insert (append) new text to the existing file? Or does it empty (truncate) the file and then write the new (longer) version? Which is a new write which would trigger tail.

comment Is it wise to run computing virtual machines on KVM?
Using a VM is slower, but not much. Only you can decide if the low (1%-ish?) slow down is worth the extra ease of recovery when using a VM. That 1% is a guess and depends a lot on which hardware you use (e.g. CPUs with or without AMD-Vi or Intel VT-x/VT-d. Same for passthough IO devices or disk access via the host OS).

comment Why does tar complaint that it cannot find the file while extracting the archive?
You change users (sudo) to a different person. That different person needs read rights on the tarball. Does that person (uid 0) have those rights? (The usual answer is: Heck yes, toor/root/admin has those rights, but but SE linux that is no longer always true.

comment I have a 24 gig RAM pc with intel Xeon and still get 3 fps on minecraft
Not sure about that. Older P4 based Xeons might be able to use 24GB and still have very slow on-board graphics. But that is reaching on my part. I think you are right for 99% of the cases. @OP: First of all. Please post a bit more information than just " I tried allocating 20 gigs to minecraft but it only uses about 1" Secondly, consider what you just wrote. Either it is limited because it want more RAM and you failed to successfully assign it, or it has much more RAM than it can use and something else limits the speed.

comment C compiler cannot create excecutables
I asked because similar questions like this onen gave the same error when GCC was not the actual compuer or when there are some linker problems (roadmr already covered that part).

comment Adjust new swap memory
If does not simply depend on you main memory. How much RAM do you typically use? (Get that as real RAM). How much do you rarely use on top of that? (e.g. usually 4-5 GB, but once per month 7GiB when recompiling QT. In that case get 2+ GiB-ish swap (8 is 6+2, and round up for some spare). In almost all cases this means swap never needs to be larger than 2-3 GiB.

comment Adjust new swap memory
no longer. Way back when we used SWAP and program were mapped to the swap and all RAM was cache we used to have a rule of SWAP being main RAM x2 or bigger. This is no longer true. Today all systems page. It might still be called a swap file and fstabn will still show 'swap' as filesystem, but the methods behind it have changed as have the sizes.

comment Adjust new swap memory
10GiB of paging? What are you trying to do? If you reguarly use more then 1GB of swap then consider buying more memory, not increasing swap. (except if ram is maxed out and you do not mind waiting a few extra weeks for a program to run).
