comment Do text files store their encoding method for later decoding?
@OldGeezer: And BTW, file cannot do reliably detect most text encodings (because that is very difficult). The man page has some information on character set detection - file mostly only recognizes ASCII, UTF-8/16, EBCDIC, and ISO-8859-x. For example, a file encoded in KOI8-R is reported as "ISO-8859-1".

comment Do text files store their encoding method for later decoding?
@OldGeezer: file has various heuristics for determining file type and encoding. Mostly, it looks for certains strings or byte sequences in the file. If you want more specific information, you'll probably have to read the source. Or just ask a separate question :-).

comment How does a server get notified about the HTTP request?
@DhiwakarRavikumar: Yes, ports are just numbers. They are made up by a program or the operating system, they do not correspond to anything in hardware.

comment How to find out if a CPU has an MMU
@PaulA.Clayton: True. However, AFAIK, all common modern OSes use the MMU to implement memory protection, so these OSes do need an MMU for memory protection. Anyway, thanks for the information; I edited my answer to clarify.

At any rate, OP already uses rsync --progress for seeing progress during a copy operation.

comment Can I run MS-Word/Excel when I don't have an internet connection?
Have you tried completely deactivating your network connection? If the network interface is active, but there is no connection, the computer might hang while waiting for an answer that will never come. Try deactivating the network connection under "Network connections" in the Windows configuration.

comment Refresh Excel document without opening it
Not an answer, but: It looks like you are really hitting Excel's limitations. Maybe you need to write (have written) a "real" program, instead of doing everything inside Excel? The code which Excel runs (VB probably?) could be extracted into a separate program.

comment 'less' command clearing screen upon exit - how to switch it off?
@K3---rnc: Scrolling with the keys definitely works on Debian. Can't say about the mouse wheel. Just ask a question :-).

comment 'less' command clearing screen upon exit - how to switch it off?
@K3---rnc: Hm, that's weird. I use less -X on multiple computers, and scrolling still works. Consider asking this as a separate question.

comment Looking for a Linux or Windows command line .WAV file checker
I took the liberty of adding a quote from the docs. It looks like this tool might answer the question.

comment Java error with kodak app
We'll need some more information: What software exactly is this (can you give a link)? Is the problem reproducible, or intermittent? It it is reproducible, how exactly? Is the error message always the same?

comment How to wipe free disk space in Linux?
The question of whether multiple wipes are necessary is answered here: Why is writing zeros (or random data) over a hard drive multiple times better than just doing it once?

comment How do I queue multiple files for copying on a Mac?
Hi, and welcome to superuser.com. You post reads more like a discussion than like an answer. Please not that this is not a discussion forum, and try to answer the question asked. Thank you! Maybe you could edit your answer to make it more on-topic.

comment Windows 7 safe mode pretends it's Windows XP?
@MDMarra: Nitpicking: You can install and multi-boot multiple Windows installations from the same partition (it's probably not officially supported, though). So only having one volume does not mean it's not a multi-boot system. Plus, each installation might be set up to only see its own partition.

comment Installing legal older versions of Windows XP
While interesting, this does not answer the question. The question was "How do I get a license", and this is about "how do I handle activation".

comment Installing legal older versions of Windows XP
The testing images have been updated, and are now available for Hyper-V, Virtual PC, VirtualBox and VMWare. See modern.ie/en-us/virtualization-tools . They are still time-limited - however, you can just roll back to an old state using the VM tools to use them forever.
