Getting MathJax Working

I got MathJax: git clone git://github.com/mathjax/MathJax.git MathJax

Using MathJax extension Went back to old solution; MathJax extension hiccupped.

old solution:

I installed the JavaScript extension[2] for MediaWiki.

I added a file mathjax.js (name doesn't matter) to extensions/JavaScript. It's content: 

var e = document.createElement('script');
e.type = "text/javascript";
e.src = "/MathJax/MathJax.js?config=wikiconfig";
document.getElementsByTagName('head')[0].appendChild(e);

(I basically copied the MathJax configuration file used at MO ... got confused because you have to remember to modify the last line)

(Not) Getting Blahtex Working

It'd be much nicer to get MediaWiki to serve MathML and use MathJax to convert only if it has to, but I haven't been able to get Blahtex[3] to compile. I've been trying to follow the instructions here [4]. I'm able to checkout blahtex and to get texvc working, but if I try make or make linux, I get 

g++ -O3   -c -o source/main.o source/main.cpp
source/main.cpp: In function ‘void ShowUsage()’:
source/main.cpp:108: error: ‘exit’ was not declared in this scope
make: *** [source/main.o] Error 1

Moving html to wiki

A useful substitution: 

<a href="([^"]*)"[^>]*>([^<]*)</a>
[\1 \2]

Handling Spam

See http://www.mediawiki.org/wiki/Manual:Combating_spam

Using SpamBlacklist extension. Using blacklists at meta.wikimedia and wikipedia, and adding additional blacklisted urls to MediaWiki:Spam-blacklist as needed.

Also installed the UserMerge extension so that I can delete junk users. In extensions directory, 

svn co http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/UserMerge

Started using CAPTCHAs: 

svn co http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/ConfirmEdit

Change text of the Special:Captcha/help at MediaWiki:Captchahelp-text (more generally, various bits of text are configurable through the Special:AllMessages page).

Was getting spam even when using ReCaptcha ... switched to Questycaptcha. Still got spam, but with no links, so added 

$wgCaptchaTriggers['edit']          = true; 
$wgCaptchaTriggers['create']        = true;

Still getting spam users created pretty regularly (every two weeks?), so I'm disabling user creation with 

$wgGroupPermissions['*']['createaccount'] = false;

Editing MediaWiki:Loginprompt to reflect that you need to contact me to create a user. To create a new user, visit Special:UserLogin while logged in.

Sitemap

Followed instructions here and pointed google webmasters to stacky.net/wiki/sitemap/ ... google complains the sitemap is html, so pointed to http://stacky.net/wiki/sitemap/sitemap-index-stacky_net_3-wiki_.xml instead. Still not working.

Okay, looking at Manual_talk:GenerateSitemap.php, it looks like the following thing should work. I've modified the indexEntry function in $IP/maintenence/GenerateSitemap.php as follows: 

407c407
<                       "\t\t<loc>$filename</loc>\n" .
>                       "\t\t<loc>http://stacky.net/wiki/sitemap/$filename</loc>\n" .

Regenerating with 

php maintenance/generateSitemap.php --server http://stacky.net --urlpath http://stacky.net/wiki

Great, that seems to make google happy. Adding daily cron job through web panel.

Templates

Added ParserFunctions extension to allow flow control in templates.

Error creating thumbnails

This error didn't used to appear, but now does. Enabling logging, I see the following behavior when I try to produce a 45px wide version of New.jpg: 

File::transform: Doing stat for /home/ageraschenko/stacky.net/wiki/images/thumb/2/2d/New.jpg/45px-New.jpg

Weirdly, commenting out the line 

$wgUseImageMagick = true;

in LocalSettings.php seems to fix the problem.

Finding Broken Links

Using the BrokenLinks extension, but it seems dodgy ... often the links it objects to work just fine.

Also handy: XHTML validator link checker

Restricted access to certain pages

Citations/references

Trunk of svn repo doesn't seem to work. Did this instead, as recommended at [6] 

wget http://upload.wikimedia.org/ext-dist/Cite-MW1.16-r62678.tar.gz
tar -xzf Cite-MW1.16-r62678.tar.gz -C /var/www/mediawiki/extensions


Setting up knotica

Have knotica add a CNAME record pointing "@" to "knotica.stacky.net". Have dreamhost fully host "knotica.sheafy.net". Mirror "knotica.com" at "knotica.sheafy.net".

One-click install mediawiki to "knotica.stacky.net/wiki".

Setting up mail

[7] 

    $wgSMTP = array(
       'host' => 'ssl://smtp.gmail.com',
       'IDHost' => 'mydomain.com',
       'port' => 465,
       'username' => 'webmaster@mydomain.com', ## or info@mydomain.com, or whatever email account you've set up for your Mediawiki installation
       'password' => 'emailpasswordforwebmaster',
       'auth' => true
    );

Mobile support

Tried MobileFrontend extension, but it gives me errors. In extensions directory, 

git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/MobileFrontend.git

then in LocalSettings 

require_once("$IP/extensions/MobileFrontend/MobileFrontend.php");
$wgMFAutodetectMobileView = true;

Trying again, using instructions at [8]. 

wget http://www.memorydeleted.com/mediawiki/skins/WPtouch_1.18_and_later.zip
unzip WPtouch_1.18_and_later.zip

put WPtouch.php and wptouch/ into skins/. Edit LocalSettings to say 

if (preg_match("/(mobile|webos|opera mini)/i", $_SERVER['HTTP_USER_AGENT'])) {
    // Different file cache dir for mobile devices
    $wgFileCacheDirectory = "$IP/html_cache_mobile";
    // Mobile skin
    $wgDefaultSkin = 'wptouch';
} else {
    // normal skin
    $wgDefaultSkin = "vector";
}

In WPtouch.php, replace /apple-touch-icon.png with /wiki/favicon.ico.
