The problem consist of creating a timelapse made of photos which have been taken with a camera which has been removed and attached to a tripod during a few months thus creating a lot of shaking. Solution, use hugin to align photos: <pre lang="bash"> #!/bin/bash align_image_stack -v -a$1 -s 2 *.jpg mkdir base for i in $(find . -maxdepth 1 -name "*.tif"); do n=".$(echo $i | cut -f2 -d".").jpg"; convert $i $n && mv $n base; done rm *....

Create a database of exif data from photos using pyexiv2 and save it in a sqlite database for futher query: <pre lang="python"> #!/usr/bin/env python import os, sys, pyexiv2, sqlite3 thumbFormats = ('JPG', 'JPEG') rawFormats = ('ARW', 'CR2') formats = thumbFormats + rawFormats tags = ['Exif.Image.LensInfo'] dbFile = 'metadata.db' conn = None cursor = None def parse(dir): cnt = 0 for root, dirs, files in os.walk(dir, topdown=False, followlinks=True): refFiles = map(str.upper, files) for file in files: fullPath = os....
The goal of this script was to have a simple script, binded with a shortcut which allows to mute/unmute all the microphones and to display a nice notification in the process. This is the simplest version working on xubuntu 14.04 with pulseaudio. <pre lang="bash">#!/bin/bash ACTION=1 #1 mute, 0 unmute SCNT=$(pacmd list-sources | grep muted | wc -l) MUTED=$(pacmd list-sources | grep muted | grep yes) if [ $? == 0 ]; then ACTION=0 notify-send -i microphone-sensitivity-medium "Microphone" "Unmutting $SCNT sources....
There is not much to say about the new xubuntu 14.04 trusty tahr and this is a very very good thing. I had quite some work to do when installing 12.04 on my Tuxedo Laptop but with 14.04 I managed to setup almost everything in 2h on a friday night. Here is a list of just a few small hick-ups: non blocking grub error while booting from my LVM root Error: diskfilter writes are not supported....
There are many, many links, threads, bugs and discussions related to this since oracle 11g installation is no longer breeze at it was the case with oracle 10g, at least on Ubuntu.

If you have a previous oracle install backup your databases with expdp....
Since my last laptop with a working CD drive is dying this a simple script which does the following ops once the CD is inserted and auto-mounter: finds the mount point copies the files ejects the CD <pre lang="bash">cd "$(cat /proc/mounts | grep iso9660 | cut -d' ' -f2 | sed -e 's#\\040# #g')" && cp * /media/backup/data/ && cd && eject /dev/sr0
Multicast might seem like a great idea for 2 problems: iptv and discovery. In my case it seemed like a very good idea for cluster node auto-discovery: no need to configure each node with all the other nodes, no need to know the number of nodes beforehand, use a single node configuration. However it seems that more and more nodes are discovered you can fall into some very dark pitfalls which could eat days and nights of your time until either you find a solution, either you revert to tcp or udp unicast....
I have an old laptop with a broken charger. The laptop works on the charger but it does not charges the battery. This should not be a problem since the battery is broken also. However I’ve noticed the laptop is very slow. After further investigation I noticed that the cpu maxfreq is always equal the the low frequency no matter the governor: cat cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq I installed cpufreq and tried setting the governor to performance, no luck....
There is a cabinet in my workplace which contains 5 Dell laptops. Now there will be a 6th and probably last Dell laptop going to that cabinet since my new laptop is not a Dell anymore. And this is not for lack of trying. And I’ve tried also Acer, Asus, Lenovo, even Toshiba. This was part of the now standard 3 year cycle of laptop renewal: make a list of requirements, search for a few weeks, get mad, search again, compromise, buy a laptop....
