Installation of Oracle client to Ubuntu 10.04 Lucid

Recently I moved from Fedora 13 to Ubuntu 10.04 on my work laptop. So, I faced again with problem to setup Oracle PHP interface. Oracle provides RPMs only and not DEBs. So, to install the client RPMs should be converted to the DEBs. It can be done easily using utility alien:
sudo alien oracle-instantclient11.1-basic-11.1.0.7.0-1.i386.rpm
sudo alien oracle-instantclient11.1-devel-11.1.0.7.0-1.i386.rpm
sudo alien oracle-instantclient11.1-sqlplus-11.1.0.7.0-1.i386.rpm
They can be installed then with sudo dpkg -i.
Don’t forget to install PHP interface to Oracle:
sudo pear install pecl/oci8
That’s it. I spent no more 15 minutes to setup PHP Oracle interface under Ubuntu. Thanks to that post!

Organize devices on the desk

After we moved to the new flat I decided to put my computer devices more efficient on the my small desk. I followed by brief guide of Van Mardian and mounted an ADSL modem and WiFi router under my desk. I don’t have so much devices which can be mount such manner but I got some free space on the desk. The next step is to mount power extender there as well.

Thanks to Lifehacker for a good point.

Embperl and %ENV

Recently I faced with problem to incorrect displaying none-latin characters on the HTML page generated by Embperl. This happened because Embperl escapes all output symbols by default. To avid it it’s needed to specify a parameter EMBPERL_OUTPUT_ESC_CHARSET = 0. For web application is works fine because Embperl check %ENV and changes its parameters according to it. But if you need to run Embperl script from command line it doesn’t work. The solution is following: add into %ENV desired parameter

$ENV{EMBPERL_OUTPUT_ESC_CHARSET} = 0;

and pass additional parameter to the Embperl::Execute – use_env

Embperl::Execute( { inputfile => my-test-file.epl,
param => [<some data>],
use_env => 1,
});
