Stereo photo taken using a Nintendo 3DS XL. As browsers don’t support MPO files yet, I had to split the file into two JPGEs, then manually align and convert to animated gif using GIMP.

O bastante de lhe bastar!
A vida é breve, a alma é vasta;
Ter é tardar.”
Fernando Pessoa
Audiobooks and podcasts are a great option to listen during flights, commuting, or doing sport activities. LibriVox – Acoustical liberation of books in the public domain, is a great platform to listen (and volunteer to record) audiobooks in Public Domain. I started with their Plato’s Phaedo read by Bob Neufeld and it was great.
sudo find /proc -maxdepth 2 -name maps -exec grep -HE ‘\(deleted\)’ {} \; | cut -d/ -f3 | sort -u | xargs –no-run-if-empty ps
Looking for libssl in specific:
sudo find /proc -maxdepth 2 -name maps -exec grep -HE ‘/libssl\.so.* \(deleted\)’ {} \; | cut -d/ -f3 | sort -u | xargs –no-run-if-empty ps
Killing all process using a deleted version of libssl:
sudo find /proc -maxdepth 2 -name maps -exec grep -HE ‘/libssl\.so.* \(deleted\)’ {} \;| cut -d/ -f3 | sort -u | xargs –no-run-if-empty sudo kill
Let this interactive.sh be the interactive program:
[bash]#!/bin/sh
read input1
read input2
echo $input1 $input2
[/bash]
This is a script feed.sh (in the same directoty) that uses heredoc to feed two lines to interactive.sh:
[bash]#!/bin/sh
./interactive.sh << EOF
asdf
zxcv
EOF
[/bash]
It work as:
[bash]$ ./feed.sh
asdf zxcv
[/bash]

10x = 9.999…

“and I know too well that these arguments from probabilities are impostors, and unless great caution is observed in the use of them they are apt to be deceptive-in geometry, and in other things too” Socrates, in Phaedo by Plato. 399 BC.
