Talk:Case sensitivity

message: Since when are user names case sensitive? In most systems I know user names are not case sensitive to avoid many problems, like users forgetting the case.  —Preceding unsigned comment added by Danobrega (talk • contribs) 08:54, 8 September 2010 (UTC)

message: I would think "case sensitivity" is correct, but as an adjective or adverb, wouldn't it be "case-sensitive" and "case-sensitively" etc.? — FREAK OF NURxTURE (TALK) 04:59, 2 November 2005 (UTC)

message: This may be not be the correct place to ask for this, but I needed to do a case sensitive web search and came up with.. nothing.
As good as Google otherwise is, it lacks this feature. Alta Vista supposedly had this, but doesn't anymore. Any suggestions? Anything on this on Wikipedia?
Having just looked at this article tonight (i.e. December 8 2009), I was extremely surprised to see that this article did not mention Google as a search engine which, as far as I know, is NOT case-sensitive, so that you will get equivalent number of hits on Google if type in a term in capitals or lower-case. This has long been my understanding on Google - am I right? ACEOREVIVED (talk) 22:14, 8 December 2009 (UTC)

replies: text: It's linked in MediaWiki:Noarticletext, MediaWiki:Noexactmatch (through the redirect case sensitive), and MediaWiki:Noexactmatch-nocreate (through case sensitive) which was created on 25, October 2008. So the visibility of this system message may explain the important rise in traffic of case sensitive, , whilst the traffic of case sensitivity alone relatively diminished. This explains the cumulated traffic and so the level of vandalism here. Cenarium Talk 01:39, 1 November 2008 (UTC)

message: Or I cannot understand what "case sensitive is"
In QBASIC IDE, you can type
X=10
print x
And then you press Enter on last line, all instances of X converted to last used casing (x).
(and running it prints 10)
If you create such a program outside IDE, it converts on load. 
(As example of case sensitive Basics I can cite Liberty Basic / Just Basic.
In them, above program stays "as is" and then run, prints 0 (because x is undefined)
)

message: In one Star Trek: Voyager novels, one of the characters meets a female Q and asks her if she is Q. "No, I'm q", she replies, "can't you hear the lower case?" How are you supposed to hear the lower case? JIP | Talk 22:01, 9 November 2011 (UTC)

message: Change the section title:

into:
Use in computer systems
Reason:  Obviously India has nothing to do with this topic, there is no mention of India anywhere else other than in this title.

message: "Current Windows file systems, like NTFS, are case-sensitive; that is a readme.txt and a Readme.txt can exist in the same directory. Windows disallows the user to create a second file differing only in case due to compatibility issues with older software not designed for such operation."
Not just older software.  One would struggle to find any newer software that is compatible with it either.  77.73.168.99 (talk) 16:28, 14 January 2014 (UTC)
thread_title: Windows - NTFS

message: In computers, some examples of usually case-sensitive data are
[...]
*filenames
[...]
Imho this is wrong: most computers use Windows and although it is possible, to use upper- and lower-case filenames in Windows with NTFS or VFAT, the file names are not case sensitive: it is impossible to create two files in the same folder, when the only difference in the filename is the case of a letter and all the file system operations are also case insensitive. --MrBurns (talk) 00:03, 27 June 2014 (UTC)

thread_title:  filenames 

message: When is either one of these approaches used? Many articles list use cases of the ways how they are stored. But what is the actual philosophy behind case sensitivity vs. insensitivity? Usually my mind is blank when I try to find something from the command line in Unix: I don't remember the file names I try to search (a big NAS for example). That's why I use case insensitive searches. Most of the commands and defaults are usually case sensitive in Unix, however. I just wonder why that is the case (no pun). Then I know a programmer often needs case sensitive searches (definitions in upper case in SQL, C, Java etc.).
Storing vs. searching, computer vs. human, content vs. filenames, different applications and use cases. Why Unix favors case sensitivity while "popular" systems favor insensitivity? Still not completely clear to me and "case sensitivity for exact matches" is a tautology as that may not always be the case either: sometimes things are stored as containers (not files) and user selects its name (it can be the same, i.e. Google Drive style). The more user side a system tends to be the more case insensitivity there usually is.  — Preceding unsigned comment added by Beoldhin (talk • contribs) 10:18, 16 December 2017 (UTC)
thread_title:  When is it used? 

message: It seems to me that "case sensitivity" is used to mean two things:
# The quality of being case sensitive - "This system has case sensitivity".
# The domain of possible ways to handle case - "What is the case sensitivity of this system.
Most of the article is about the second meaning - but the lead defines only the first. I will change it to define "case sensitivity" in the second meaning, alongside "case sensitive" and "case insensitive". NisJørgensen (talk) 22:13, 2 July 2019 (UTC)
