lighttpd 1.4 + php 5.4 + drupal clean urls

Here’s what I’m using for drupal powered by lighttpd 1.4 & php-fpm 5.4 :

        ### shorten /files, /themes
        ### 2012-01-30 - randall
        ### %0 = entire hostname
        ### %1 = prefix of *.*.example.com
        url.rewrite-once = ( "^/files/(.*)$" => "/sites/%0/files/$1")
                             ###"^/themes/(.*)$" => "/sites/%0/themes/$1")

        ### Deny access to backup_migrate module dumps
        $HTTP["url"] =~ "^(\/sites\/(.*)\/files\/backup_migrate\/)" {
            url.access-deny = ("")
        }

        ### clean urls for >= lighttpd 1.4.24
        ### http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ModRewrite#urlrewrite-repeat-if-not-file
        ### 2012-01-05 - randall - fix for drupal 7 with image cache
        url.rewrite-if-not-file = (
            "^\/([^\?]*)\?(.*)$" => "/index.php?q=$1&$2",
            "^\/(.*)$" => "/index.php?q=$1"
        )

        ### "Fix" for Drupal SA-2006-006 (but let imagecache work)
        ### http://www.linode.com/forums/viewtopic.php?t=5300%3E
        $HTTP["url"] =~ "^(\/sites\/(.*)\/files\/)" {
            $HTTP["url"] !~ "^(\/sites\/(.*)\/files\/imagecache\/)" {
                fastcgi.server = ()
            }
        }

Show Library folder / directory in OS X Mavericks (10.9)

The process is the same as it has been for many years, to reveal the Library folder/directory in Mavericks:

  1. open Terminal
  2. type the following
    sudo chflags nohidden ~/Library 
  3. hit enter, and then type your password if prompted

Internal linkage mini how-to

This post was authored by James Redfern:

“I use a sharpened wire to make first hole to servo location. I
simulate where control horn will be and do the best I can to end up at
servo horn. Long wire helps with this. Once I like where wire is,
(usually I have to take 2 stabs to get it close enough for step 3. I
pull the wire most of the out, but making sure it will follow hole to
correct location. Then with wire pulled out, I heat wire a couple
inches up. Once hot slide wire in and move in a circle to enlarge hole
only where it exits wing.  Then remove wire completely, heat first
couple inches of wire. Carefully open lower part of hole w circular
motion. That quick,  perfect tubes.”
