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 How Do I install Ubuntu on a Dell laptop with no current operating system and on a Acer swift with windows 8
Use the post Tim linked to. The only difference between when it was written (2011) and now is that you almost certainly want the 64 bit flavour. As for the Acer: Wrong group to ask, but if (big if with win8) you got a DVD then just insert the install DVD. If you did not then it gets more complex yet this still remains the wrong site to ask on.

comment Cannot connect to some wireless networks
Why do you suspect the driver when it works at home and with some other networks. (Assuming it only fails on some of the other/not-home networks). Why do you not get any DNS replies? Are the DNS servers on your laptop configured via DHCP? Does the DHCP server reply with any DNS server IPs (that part is OPTIONAL for DNS). Etc etc. Please add more information you your post.

comment Cron process sends email, where are these sent emails?
No, it does not. It only sends them. It does not archive them or keep local copies.

comment Cron process sends email, where are these sent emails?
Are you asking where the mail gets sent to (as in to root@host.tld, or the users mail when the crontab was not for root), or if the cronjob keeps a mail folder with things like 'sent mail', 'inbox', 'spam' etc etc? In the last case the answer is Nope. It just sends the mail and does not keep any logs.

comment find is using a LOT of resources - how do I find out why?
Does it always slow down around the same time? Do you run updatedb (locate) via cron? Are there any disk errors?

comment Can't detect hard drive
1) What do you mean with "formatted with a linux partition"? Did they make a single partition on the disk (similar to dangerously dedicated) or is the disk installed in the normal way. E.g. a MBR or EUFI, and then partition(s) ? 2) You write that the BIOS detects it. That means the hardware is probably OK. But which hardware? A SATA port on the motherboard? On a plug-in card? It is on a HBA? 3) Can you please add the output from dmesg during the boot. (To check if or which disk controllers and disks are detected).

comment Why do I have 2 IP addresses for the same computer?
Doug: Same MAC means that the IPs point to the same NIC.

comment Why do I have 2 IP addresses for the same computer?
How did you set up an static IP? If you did so the first time you booted the Ubuntu installer then I have no idea how this happened. However if you first booted using DHCP (and thus got an IP in the router list) and later changed to a static IP then the router might be remembering both the new state and the old state.

comment Dell Poweredge R410, ubuntu(14.04) running dead slow
If the system is slow then it is waiting on something. Either on the CPU (unlikely, a E5503 is modern enough), disk, network, ... To answer what it is waiting on you need to post more information.

comment make ntfs hdd only visible in Ubuntu
Hiding it will be quite hard since you seem to want a 'real NTFS' filesystem on the drive. However depending on your goal you could just not assign a drive letter under windows.

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 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.
