Getting a LAMP install going with full UTF-8 (not necessary with gentoo, it already defaults to UTF-8 everywhere).

php unicode string

Have you ever wanted to express unicode code points in a php string

$string = "Hello World \u4f60\u597d\u4e16\u754c";

(which is...)

$string = "Hello World 你好世界";

Try this:

$string = ustring("Hello World \u4f60\u597d\u4e16\u754c");

function ustring($string)
{
return preg_replace_callback("/\\\\[Uu]([0-9A-Fa-f]{4})/",'matcheduchar', $str)."\n";
}
function matcheduchar($matches)
{
$num = hexdec($matches[1]);
if($num<=0x7F) return chr($num); if($num<=0x7FF) return chr(($num>>6)+192).chr(($num&63)+128);
if(0xd800<=$num && $num<=0xdfff) return '';//invalid block of utf8 if($num<=0xFFFF) return chr(($num>>12)+224).chr((($num>>6)&63)+128).chr(($num&63)+128);
if($num<=0x10FFFF) return chr(($num>>18)+240).chr((($num>>12)&63)+128).chr((($num>>6)&63)+128).chr(($num&63)+128);
return '';
}

Geany Find in Files Dialog

I opened the geany Find in Files Dialog and it kept defaulting to ISO-8859-1. It kept bugging me cause I wanted it to default to UTF-8

Turns out... in the source code of Geany 0.20 says this:

/* set the encoding of the current file */
if (doc != NULL)
    enc_idx = encodings_get_idx_from_charset(doc->encoding);
gtk_combo_box_set_active(GTK_COMBO_BOX(fif_dlg.encoding_combo), enc_idx);

So my problem was I had an ISO-8859-1 file open... then when I went todo CTRL-SHIFT-F, find in files, it defaulted to the charset of the file that was already open. All I had to do was change the encoding of my file (that was already open) to utf8 and the find in files defaulted correctly.

hg style file on linux

http://mercurial.808500.n3.nabble.com/How-to-get-a-list-of-changed-files-td808109.html

save this file:

http://mercurial.808500.n3.nabble.com/attachment/808110/0/map-cmdline.gward

to this folder:

/usr/share/mercurial/templates/

now you can do:

hg log -r tip --style gward -v

or setup your ~/.hgrc

[ui]
style = gward
[defaults]
log = -v

now you can do:

hg log -r tip

Java Servlet 2.5 API javadocs for Tomcat 6

Oh my goodness, I am starting to dislike oracle. When I google for "java servlet 2.5 api docs"

The first link is:
* http://www.oracle.com/technetwork/java/javaee/servlet/index.html

and when I go to the page:
* http://tomcat.apache.org/tomcat-6.0-doc/index.html

it has a link to
* Servlet API Javadocs - The Servlet 2.5 API Javadocs.

But the link is a dead link that redirects to
* http://www.oracle.com/technetwork/java/javaee/servlet/index.html

ug.

Well I finally found out that javaee 5 uses servlet api 2.5 so this might work
http://download.oracle.com/javaee/5/api/javax/servlet/package-summary.html

But so might this:
