 Institution = {International Organization for Standardization},
 address = {Geneva, Switzerland},
 Title = {Document management---{P}ortable document format---{P}art~1: {PDF}~1.7},

remove i386 from amd64 Ubuntu systems

Upgrading an amd64 Ubuntu to oneiric caused the package manager to load not only amd64 list of packages, but also i386 ones. The solution is to remove the multiarch file from /etc/dpkg/dpkg.cfg.d :
# cd /etc/dpkg/dpkg.cfg.d 
# mv multiarch multiarch.backup 
# aptitude update 
Since Ubuntu 12.10, you should use %dpkg --remove-architecture i386

figure dash in XeLaTeX

Figure dash ‒ is used for dashes in numbers (0763‒5345). It does not indicate a range, for which the en dash is used. In LaTeX there are commands for:

• endash: \textendash
• emdash: \textemdash
• minus: \textminus

Because the code for figure dash is 0x2012 I define the following command for a figure dash in XeLaTeX:

\newcommand{\textfigdash}{\char"2012 }%figure dash ‒

latex warning output

To make latex print an warning at output one can use:

• \@latex@warning{My message}prints "file.tex:10: My message on input line 10"
• \@latex@warning@no@line{My message}prints "file.tex:0: My message"

One can define a \todo command to get warnings about uncompleted sections. The following todo command will print a

TODO...

in the PDF and the warning message passed as a parameter \todo{Finish Thanks section!}

Code for pasting in LaTeX package(.sty file)

\makeatletter
\newcommand{\todo}[1][]{\@latex@warning{TODO #1}\fbox{TODO\dots}}
\makeatother


bugfix> remove unwanted spaces in tokenizer package

As notice here \GetTokens inserts unwanted spaces. The bugfix is to use the following code instead of just "\usepackage[trim]{tokenizer}":

\usepackage[trim]{tokenizer}  
 
\def\SH@GetTokens#1,#2\@empty{%
    \def\SH@token{#1}%
    \ifx\SH@trimtokens\SH@true% strip spaces if requested
        \TrimSpaces\SH@token%
    \fi%
    \SH@DefineCommand{\SH@FirstArgName}{\SH@token}%
    \SH@DefineCommand{\SH@SecondArgName}{#2}%
    }
\def\SH@CheckTokenSep#1,#2\@empty{%
    \def\SH@CTSArgTwo{#2}%
    \ifx\SH@CTSArgTwo\@empty%
        \edef\SH@TokenValid{\SH@false}%
    \else%
        \edef\SH@TokenValid{\SH@true}%
    \fi%
    }

I will report this bugfix to the developer Sascha Herpers

get rid of latex badboxes on framed figures

If you include in a LaTeX document a graphics file with a frame
\fbox{\includegraphics[width=\textwidth]{file.png}}
you will get a badbox warning. The solution is to substract twice the size of the frame:
\fbox{\includegraphics[width=\textwidth-\fboxrule-\fboxrule]{file.png}}
For multicolumn:
\fbox{\includegraphics[width=\columnwidth-\fboxrule-\fboxrule]{file.png}}

Translate BIG webpages using Google Translate JS API

Today I have released yet another open source project : zgtranslate . It is a Javascript library that could be used to translate large webpages using Google Translate JS API.

Google provides a widget that can be placed in the html code of the webpage, but there are some nasty things about it:

1. it requires flash (and I have flash removed)
2. it translates just the current page, but not the next linked page (althow it should as it says in its help)

So I decided to make my own translator. Because Google Translate JS API can only process small texts we need to split the (large) webpage into smaller pieces that can be send to hungry Google for processing. I have implemented this split in my library.

Usage is very simple: just include the zGTranslate.js script in your webpage, and set startTranslate(id,language code) to be called when something is clicked (first example) or auto(second example) when the page was loaded.

You can download the examples and the library and see it in action.

Note: as stated in issue 1, the library does not yet works with IE6. bug fixed now

$url = 'http://www.gravatar.com/avatar/';
$url .= md5( strtolower( trim( $email ) ) );

$url = '<img src="' . $url . '"';
foreach ( $atts as $key => $val )
$url .= ' ' . $key . '="' . $val . '"';
$url .= ' />';

latest googletalk-call not working with kopete in Ubuntu Maverik

The latest kopete-gcall 4:4.5.0b-0ubuntu3 does not contain the executable /usr/bin/googletalk-call so kopete gives the following error message: "Cannot start process googletalk-call. Check your installation of Kopete.".
I recommend installing the previous version of kopete-gcall that can be found here.
The bug report is here.
