Edo Wiki

I installed a new debian 8.6 from a CD on an already partitioned hdd. The disk is partitioned as

/dev/sda1 /
/dev/sda5 /home

so I could reformat only the root filesystem keeping the files of the users.

adduser --no-create-home --home /home/edo edo
chown -R edo:edo /home/edo
service apache2 restart

Follow the directions from DebianWiki.

apt-get install apache2 php5
a2enmod userdir
chgrp -R www-data /home/edo/public_html/

Follow this link.

I installed the amd64 architecture. It may be useful to install a multiarch enviroment (especially for Android development) Sometimes it may happen that files on the hard disk cannot be executed with a confusing message file not found. Even if they are there.

dpkg --add-architecture i386
apt-get update
apt-get install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386

Developing on a device. Changes needed to make Android studio work: the above mentioned multiarch,

usermod -a -G plugdev edo

I use the special color filter to map dark into light colors and viceversa.

To achieve it one should first use a negative filter followed by a swap-hue filter.

RCP neg.a, temp.a;
MAD temp.rgb, -neg.a, temp, 1.0;

MOV result.color, temp;
