Notes - Giving more stability to the mood lamp

2011-10-21T16:46:00.004+02:00

I had some troubles setting up supervised process for the python binary running the mood lamp, I guess it might be related with the fact that python is also calling gnuplot subprocess via os.system call, and daemontools might be a bit lost with that (not sure).

So in order to have the binary running more stable and making it strong against spurious crashes I did a little script that is running under a screen session:

#!/bin/bash
CRASH_COUNTER=0
while : ; do
python ./animo_mundial.py
let CRASH_COUNTER=$CRASH_COUNTER+1
echo $CRASH_COUNTER > /tmp/animo_crash_counter.txt
sleep 10
done

If yo want to store chart data for public serving, It's necessary to have dropbox running, due to encryption issues maybe if you reboot your computer it will not run until you log in and mount your home so first thing run dropbox

service dropbox start

bash -c '/usr/bin/screen -dmS minic minicom -o'

#this is if you put some services with symlink under /service

#svscanboot will run them, but Im not using them form now
csh -cf '/command/svscanboot &'

#main soft running supervised and under a screen terminal
bash -c '/usr/bin/screen -dmS lamp supervise /home/me/scripts/animo'

Im using a perl script that calls selenium server, then I use Beautiful soup to nicely parse the rendered output coming from selenium. Probably using webkit could be done more nicely but this way is easy and quick to setup.
Just wanted to write this note so I don't forget the pipes that I'm doing. :)

Really it is not needed to get data first with perl, rc selenium export to python (Remote Control) it is enough later to get the source and parse it.

To get the source code in python use:
data = sel.get_html_source()

if you're using perl:
my $data=$sel->get_html_source();

Notes - Monitor an event and send email when it occours

2011-09-11T19:44:00.001+02:00

tail -f /var/log/messages | awk '/now/ {system("mail -s 'hi' myemail@mydomain.com < /dev/null")}'

interesting for /var/log/auth for example...

Notes - Record shell session for later replay (educational use)

2011-09-11T19:23:00.000+02:00

script -t 2> tutorial.timing -a tutorial.session
type ‘exit’ to end the recording.

Replay goes like this
scriptreplay tutorial.timing tutorial.session

workaround for skype without headphones on ubuntu lucid 64

2011-09-10T21:12:00.003+02:00

I was having some issues with skype and making it work in Ubuntu without using headphones. My monitor has built in camera and microphone that makes much more easy any videoconference.

The main issue was a kind of strange noise mixed with the output sound and incoming video not appearing.

So for the first issue, the strange noise, I had to disable pulseaudio by:

creating a client.conf in your .pulse dir in ~ and put the line "autospawn=no" in it. It would be good to turn back on autospawn after you have done what you need to do.

source: http://askubuntu.com/questions/8425/how-to-temporarily-disable-pulseaudio

To enable incoming video make sure cairo-dock is disabled, for some reason there is a bug that makes it interfere with X11 and skype.

But when re-running pulseaudio to get all controls back I get missing options, that I cannot figure out yet how to get, didnt spent more time on it, as this is an skype issue. Gmail video web conference have no problem at all with pulseaudio.

dani@mypc:~$ /usr/bin/pulseaudio --start --log-target=syslog

dani@mypc:~$ start-pulseaudio-x11

So had to comment out again the autospawn so pulse audio spawn during boot. At least useful to know it if someday for some reason you need to use skype.

Installing ubuntu from Internet via usb key

2011-09-04T16:58:00.002+02:00

Dammit, after 2 weeks vacations without using my main desktop pc, ubuntu natty stopped working. Don't have time to troubleshoot, so rolling back to LTS lucid.

Got the netboot.tar.gz file from:
http://archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/

and then wrote it to a usb key with imagewriter
sudo apt-get install usb-imagewriter
sudo usb-imagewriter
info from:
https://help.ubuntu.com/community/Installation/FromImgFiles

boot from usb and install

Le encanta tomarse el café de los sábados junto a la ventana, dice que la temperatura es perfecta, diecisiete grados. Los ninyos por alguna extranya razón aun no están gritando en la calle con lo que todo esta muy tranquilo y puede escuchar como por una de esas ventanas, no se si es la mía, "fue en un pueblo con mar una noche"

Los barcos del río, aunque no consigue verlos desde su ventana, siguen atracados, como siempre, pero me ha dicho que las amarras que los unen a la ciudad se están debilitando y tarde o temprano zarparan, sin prisa pero sin pausa. Hace un tiempo fue capitán de uno de esos barcos, el mas bonito de todos, el que tenia escrito en su proa "Elle"

Se le termina el café, pero no hay problema ya que siempre hace para dos, sigue cocinando para dos y pone la mesa con unas velas, también se afeita y se pone camisa y esconde las piernas debajo de la mesa para que no se le vean las espardenyas que se le han roto porque como siempre se le olvid'o cortarse las unyas.

Se ha dado cuenta de que lo miraba por la ventana y ha cerrado una especie de cortina que m'as bien parece una s'abana, bueno, ya seguir'e mirando en otro momento o le llamo mas tarde para ver que hacemos.
