'''MySQL'''

[[Open source]] [[RDBMS]] software that uses [[SQL]] for inserting, selecting and updating data. Very fast, capable, flexible, and runs on Unix, Linux, Mac and Windows platforms .

According to MySQL's FAQ, "the official way to pronounce MySQL is ''My Ess Que Ell'' (not ''my sequel''), but we don't mind if you pronounce it as ''my sequel'' or in some other localized way".

Mhouliston: reply to MySQL pronounciation

I would venture to say that the pronunciation is not that rigid. Why enforce a certain pronunciation if it is a decidedly ambigous issue?

It is quite common to say, when speaking, (e.g.) "make a sequel query", rather than "make an SQL query". Often in print one sees SQL prefixed by 'an' rather than 'a' which suggests that the author is suggesting the initialism pronunciation but it seems as though plenty of people say sequel so why would one claim that is not appropriate?

Who is to say that (e.g.) <tt>/etc</tt> ''must'' be pronounced ''ee tee see'' rather than ''et see''?

[[User:Marcel|Marcel]] 22:39, Mar 6, 2004 (EST)

----

In the case of MySQL, I'd say the company that makes the software is the one that should decide how it ought to be pronounced. See this page of their FAQ for the pronounciation guide: http://www.mysql.com/doc/en/What-is.html

With that said, it may not be relevant to leave that particular bit of information in the wiki entry. Not sure. If you don't like it, take it out :-)

Mhouliston: linko

An emulator is a program that simulates an entire computer or similar device on a computer or other similar device. (Yes, that's ambiguous; we'll get there)

*Common uses include gaming; many people simulate outdated consoles on their computers. One can even plug in real console gamepads to one's computer using special adapters to further replicate the "console feel".

OpenGL

2004-03-07T03:04:10Z

Mhouliston: s/grahpics/graphics

OpenGL is the de facto standard API for modern 3d graphics in Linux. It was originally developed by SGI inc. The official page with the specification can be found at http://www.opengl.org/

In most cases under linux, it's provided by the mesa 3d graphics library. Mesa doesn't have a license to call itself officially openGL. But the latest version of mesa (6.x) now supports the openGL 1.5 API. Also note that mesa doesn't only support linux+X11, it can be used on a whole range of other platforms.
http://mesa3d.sf.net

The mesa library and drivers are included in [[XFree86]], so are also included in most linux distributions. The mesa lib can use hardware acceleration to speed up rendering by using the [[DRI]] projects interface and can fall back on software rendering when the driver doesn't support this.

For some graphic cards there are proprietary drivers that support 3D hardware acceleration (they normally come with their own closed source openGL libraries):

For Nvidia cards you can get Nvidia drivers directly from them http://www.nvidia.com.

For ATI cards you can get drivers here

Instant messaging

2004-03-07T02:53:51Z

Mhouliston: added links to messaging protocols

'''Instant Messaging''' (IM) includes networks like AOL Instant Messenger ([[AIM]]), [[ICQ]], [[Yahoo!]], [[MSN]] Chat, and [[Jabber]]. Using a client you connect to one of these networks in order to "chat" with others who are logged into the same network. Originally these networks used typed text to "chat" but some of these networks now allow voice and video "chatting".

IM differs from [[Internet Relay Chat]] (IRC) mainly in the way that people use it. IM was implemented mainly so that internet users could "instantly" and easily talk to someone, somewhat like picking up a phone and calling the person. IRC is typically more reminiscent of going to a coffee shop and "hanging out".

IM first took off as a general [[Internet]] tool when ICQ released their first client. This was mainly a copy of AOL's internal chat network. Soon after AOL released a general internet chat client, AIM, which would allow anyone with internet access to chat with anyone else on the AIM network, including AOL's paid subscribers. Eventually Yahoo! and MSN as well as other 3rd party companies joined in.

Most IM clients for Linux (or Unix clones in general) are reverse engineered and not officially sanctioned by the network owner-operators. In fact most of the companies have made concerted efforts to kill off the open source or 3rd-party clients. Most of the time this consists of switching the proprietary communication protocol around to break the unauthorized clients.

* [[Gaim]] is a very successful, popular and featureful AIM client 
* [[Kopete]] is a multi-protocol chat client 
* [[Bitlbee]] is a chat to irc proxy, essentially, AIM/IM from ""any"" irc client 
* [[Centericq]] is a scriptable text-mode ICQ/Yahoo/AIM/IRC client

Of course, if you're feeling adventurous, you can install a (public) [http://www.jabber.org/software/serverdetail.php?projectID=2&PHPSESSID=acf7d9b504b23218c4134f810111a648 Jabber] server. A Jabber server can relay messages from one instant messaging system to another. These mechanisms are called transports.
Using your own Jabber server, you can use your favorite Jabber client to connect to any service (whether it is ICQ, AIM, MSN or Jabber) you want. You won't need a multi-protocol client.

'''Kopete''' is a flexible and extendable multiple protocol instant messaging system.

The goal of Kopete is to provide users with a standard and easy to use interface between all of their instant messaging systems.

It supports many messaging protocols like [[Jabber]], [[ICQ]], [[AIM]], [[MSN]], [[Yahoo]], [[IRC]], [[Windows LANs]], [[GaduGadu]], and [[SMS]].

Tar

2004-03-07T02:34:58Z

Mhouliston: s/explicity/explicitly

===tar===

The simplest way to decompress an archive is to use:

tar -xvf filename

What this means is, decompress something x, tell me explicitly what's happening v, don't use [[stdin]] (don't type in the archive) use an actual file f.

This allows you to do many more intersting things, for example you can pipe output in tar format to tar (just omit f) and have it untar it.

===tar.gz===

[[Gzip]] requires the z option, transforming the command to:

tar -xvzf filename

===tar.bz2===

[[Bzip2]] requires the j option:

tar -xvjf filename

Bzip2recover

2004-03-07T02:29:49Z

Mhouliston:

'''bzip2recover'''

Usage: bzip2recover filename

Attempts to recover data from a damaged file compressed with bzip2. If the file contains any blocks with salvageable data, each block is written to a file with a name such as recooo1file.bz2, recooo2file.bz2, etc.

Mhouliston:

Bzip2

2004-03-07T02:28:51Z

Mhouliston: moved bzip2recover to separate entry

bzip2 uses a sophisticated algorithm to compress files that is up to 30 percent faster than that used by [[gzip]].

Usage: bzip2 [option] filename

By default, bzip2 does nor overwrite existing output files. Use the --force option to override this setting. However, the program deletes input files by default. Use --keep option to override this setting and writes the compressed file with the .bz2 extension.

EXAMPLES

bzip2 test.dat - Compresses the specified file

bzip2 --keep test.dat - Compresses the specified file without overwriting the input file.

This allows you to do many more intersting things, for example you can pipe output in tar format to tar (just omit f) and have it untar it.

===tar.gz===

[[Gzip]] requires the z option, transforming the command to:

tar -xvzf filename

===tar.bz2===

[[Bzip2]] requires the j option:

tar -xvjf filename

Unzip

2004-03-07T02:26:14Z

Mhouliston: added .tar.gz info

===Basics===

unzip is the most straighforward of the decompression utilities. To invoke it simply use:

unzip filename

This will create all the appropriate subdirectories.

Note that for .tar.gz files, calling [[tar]] with the -z flag is simpler than unzipping then untarring.

===Features===

-q will make unzip quiet, quite useful to avoid clutter. 
-f will extract only newer, or non-existing files, nice for just updating. 
-t will test an archive to make sure it's good ([[zip]] can fix it many times)

Mhouliston: reply to Spam vs SPAM

so. we can't just have a redirect from PERL to Perl, or from Perl to PERL, lest a flame war start. how is this to be resolved. there is already an extensive entry for PERL.

the perlfaq says that it should not be PERL but that does not seem to be particularly set in stone, esp. since perl is ostensibly an acronym and as such potentially warrants all caps.

----

There is no current '''PERL''' page, actually. It might best to take the existing '''Perl''' and '''Perl tips''' page and stick the whole shebang under '''PERL'''. Then add redirects thusly:

Perl -> PERL
 
perl_tips -> PERL

 
Sound ok?
[[User:Mhouliston|Mhouliston]] 18:54, Mar 6, 2004 (EST)
----

What about a flip flop?

PERL -> Perl
 
perl_tips -> Perl

because of this in perlfaq1:
<code>
What's the difference between "perl" and "Perl"?

One bit. Oh, you weren't talking ASCII? :-) Larry now uses "Perl" to
signify the language proper and "perl" the implementation of it, i.e.
the current interpreter. Hence Tom's quip that "Nothing but perl can
parse Perl." You may or may not choose to follow this usage. For
example, parallelism means "awk and perl" and "Python and Perl" look
OK, while "awk and Perl" and "Python and perl" do not. But never write
"PERL", because perl is not an acronym, apocryphal folklore and post-
facto expansions notwithstanding.
</code>

----

A similar (though less difficult) thing happened with [[Spam]] and [[SPAM]]. Perhaps page titles should be case-insensitive in general.

[[User:Muir|Muir]] 19:36, Mar 6, 2004 (EST)

It might save some trouble, yes. On the other hand, case sensitivity is sometimes useful - compare [[CD]] and [[cd]] for example.

Q: I need a help link that explains the editing syntax of this wiki. Where is it?

A: [[Wiki_markup]]
----
Q: How do you delete a redundant page? I accindentally created a page that was already covered. I now want to remove it. Nothing liks to the page anymore, but it still exists. I could not find it in the Wiki documentation anywhere.

A: Looks like it's an [http://meta.wikipedia.org/wiki/Meta:Deletion_policy admin-only option]. Presumably there's some way to request a deletion. Meantime, I guess you could [http://meta.wikipedia.org/wiki/Redirect redirect] your accidental page to the existing one.

----
Q: What about #REDIRECTS(s) to pages that don't exist send you to that page in edit mode rather than displaying the soon to be redirected away from page with a list of the form:

1. REDIRECT Page To Redirect To?

A: Not sure I understand your question, but hopefully this will help:
You can create a redirect page to a page that doesn't exist yet. However, it will take you straight to the edit section of the nonexistent page. Until someone either changes the redirect or writes some content in the new page, it'll stay like that.

Note that you can't have a list of options on a redirect page, only one redirect is allowed, otherwise the redirect page is invalid.

From the perldoc: 
Perl is a high-level programming language with an eclectic heritage written by Larry Wall and a cast of thousands. It derives from the ubiquitous C programming language and to a lesser extent from sed, awk, the Unix shell, and at least a dozen other tools and languages. Perl's process, file, and text manipulation facilities make it particularly well-suited for tasks involving quick prototyping, system utilities, software tools, system management tasks, database access, graphical programming, networking, and world wide web programming. These strengths make it especially popular with system administrators and CGI script authors, but mathematicians, geneticists, journalists, and even managers also use Perl. Maybe you should, too.

=== Sample Perl Program ===
&#35!/usr/bin/perl -w 
print "Hello World!\n";
<hr>
The first line is the [[shebang]] line, it identifies the location of perl. If you don't know where perl is located, you can type 'which perl' and it should show you where it is. If perl is not in your path or installed on your system it will show you nothing. Most distributions come with perl already installed.

Mhouliston: removed link to self

'''Patch''' only has a small job, but it does it quickly and efficiently. It takes a sourcecode file (or any other file for that matter) and a [[diff]] file based on changes that have been made to another copy of the source. It then merges the two, adding the changes specified to the source file. This is particularly useful for allowing developers to collaborate through [[CVS]] repositories.

Originally written by [[Larry Wall]], also the author of [[Perl]].

[http://www.fsf.org/software/patch/patch.html#TOCintroduction Patch Homepage]

patch, noun, an update applied to a software [[application]] or [[operating system]] for the purpose of fixing bugs or exploits or for adding features.

patch, verb, to use a patch to update a bug or an exploit or add a feature to a piece of software or an operating system.

Diff

In short, '''diff''' is a tool for comparing two input files and informing the user either via the standard output or a file as to the differences between them. It supports both [[ASCII]] and [[Binary]] comparisons allowing you to check for differences and similarities in both text/source files and compiled binaries. It's primary application is for use with the [[patch]] tool, allowing you to merge two source code files based on the output of a diff comparison.

'''Emacs''' is a powerful (some might say too powerful) [[Editor|Text Editor]] created and maintained by the [[GNU]] project. AT it's heart is a [[LISP]] interpretter, allowing it to perform highly complex tasks with a great degree of customization. It supports syntax highlighting, [[CVS]], [[diff]]/[[patch]] and just about anything you could wish to (or not for that matter) write using the built-in LISP extensibility.

*Advantages:
** Hardly anything it can't do ...
** It has many optional modules that serve specialised purposes

*Disadvantages:
** emacs is a huge and complex program
** steep learning curve

Latest stable release, 21.3 was released on March 24, 2003

Else is very nifty, the base language files need some
customisation, though (mind you, the C ones are great,
C++ needs work, didn't look into the others in detail).
