Life was much easier when blackberry and Apple were just fruits

Sad but true fact Life was much easier when BlackBerry and Apple were just fruits!.

I don’t know about others but I have difficulties to adjust my body to the fast pace life has taken. Life would was easy and more fun without all this technology. Now even going to a pub you can’t escape the “doom” of technology. If the tech hype continues the way it does or something drastic doesn’t happen I guess all people on earth will get completely crazy …

I thougth about how this techno-mambo jumbo can be stopped on a wide scale and the only idea I have is a weapon that blocks all tech equipment world-wide. I hope someone will develop it soon and press the destory button SOON ! :)

How to convert any internet Webpage to PDF from command line on GNU/Linux

Linux webpage html to pdf command line convertor wkhtmltopdf

If you're looking for a command line utility to generate PDF file out of any webpage located online you are looking for Wkhtmltopdf
The conversion of webpages to PDF by the tool is done using Apple's Webkit open source render.
wkhtmltopdf is something very useful for web developers, as some webpages has a requirement to produce dynamically pdfs from a remote website locations.
wkhtmltopdf is shipped with Debian Squeeze 6 and latest Ubuntu Linux versions and still not entered in Fedora and CentOS repositories.

To use wkhtmltopdf on Debian / Ubuntu distros install it via apt;

linux:~# apt-get install wkhtmltodpf
...

Next to convert a webpage of choice use cmd:

linux:~$ wkhtmltopdf www.pc-freak.net pc-freak.net_website.pdf
Loading page (1/2)
Printing pages (2/2)
Done

If the web page to be snapshotted in long few pages a few pages PDF will be generated by wkhtmltopdf
wkhtmltopdf also supports to create the website snapshot with a specified orientation Landscape / Portrait

-O Portrait options to it, like so:

linux:~$ wkhtmltopdf -O Portrait www.pc-freak.net pc-freak.net_website.pdf

wkhtmltopdf has many useful options, here are some of them:
 

  • Javascript disabling – Disable support for javascript for a website
  • Grayscale pdf generation – Generates PDf in Grayscale
  • Low quality pdf generation – Useful to shrink the output size of generated pdf size
  • Set PDF page size – (A4, Letter etc.)
  • Add zoom to the generated pdf content
  • Support for password HTTP authentication
  • Support to use the tool over a proxy
  • Generation of Table of Content based on titles (only in static version)
  • Adding of Header and Footers (only in static version)

To generate an A4 page with wkhtmltopdf:

wkhtmltopdf -s A4 www.pc-freak.net/blog/ pc-freak.net_blog.pdf

wkhtmltopdf looks promising but seems a bit buggy still, here is what happened when I tried to create a pdf without setting an A4 page formatting:

linux:$ wkhtmltopdf www.pc-freak.net/blog/ pc-freak.net_blog.pdf
Loading page (1/2)
OpenOffice path before fixup is '/usr/lib/openoffice' ] 71%
OpenOffice path is '/usr/lib/openoffice'
OpenOffice path before fixup is '/usr/lib/openoffice'
OpenOffice path is '/usr/lib/openoffice'

Debian and Ubuntu version of wkhtmltopdf does not support TOC generation and Adding headers and footers, to support it one has to download and install the static version of wkhtmltopdf
Using the static version of the tool is also the only option for anyone on Fedora or any other RPM based Linux distro.

A Black and White Story and To Download an Apple a nice artistic videos produced by a friend

Tuesday, April 26th, 2011

Here are two really nice videos produced by Daniela Popova.

One is called Black and White Story and the other one is with the funny name To Download an Apple

The videos was produced for her Graduation assignment in NATFA (National Academy of Theater and Film arts).
Even better the Black and White Story Video has been selected for the Festival of the Orthodox Christian Cinema in Moscow.
The movie was selected by a the jury on the festival (a professor) who realized there is a deeper spiritual meaning behind the Black and White Story

The Black & White Story Video has also an outstanding bulgarian national folklore music combined with some modern day music, just check it out and enjoy.

The second movie To Download an Apple is a humorous one and I believe presents the sometimes stupid and serious efforts we do to follow fake imaginative goals.

To Download an Apple

As Daniela is a Christian the movies contain also a hidden Christian messages ;)
I greet her for the great work! Considering the uniqueness of the videos it’s obvious Daniela is really talented!
I’m looking forward to see some more from her works.
