First, you need an AWS account with your access keys, a EC2 security group accepting TCP connections on port 6800 and a key pair for the selected region. After that you must choose an Ubuntu EC2 image, here you can find a list of Ubuntu AMIs.

We need to create an user data script with the following content

#!/bin/bash
# filename: user_data-scrapyd.sh

# Add Scrapy repositories and key
echo "deb http://archive.scrapy.org/ubuntu precise main" > /etc/apt/sources.list.d/scrapy.list
curl -s http://archive.scrapy.org/ubuntu/archive.key | apt-key add -

# Install debian package
apt-get update && apt-get -y install scrapyd-0.16

# Restart scrapyd
service scrapyd restart

finally we can launch an instance using boto on the python console

$ python
>>> with open('user_data-scrapyd.sh') as f:
...  user_data = f.read()
... 
>>>
>>> import boto.ec2
>>> conn = boto.ec2.connect_to_region("us-east-1",
...    aws_access_key_id='my_aws_access_key',
...    aws_secret_access_key='my_aws_secret_key')
>>> conn.run_instances('ami-da0d9eb3', user_data=user_data, key_name='main', instance_type='t1.micro', security_groups=['default'])
Reservation:r-89a2aef3
>>> reservations = conn.get_all_instances()
>>> reservations
[Reservation:r-89a2aef3]
>>> instances = reservations[0].instances
>>> instances
[Instance:i-d4a2c1b8]
>>> i = instances[0]
>>> i.state
u'pending'
>>> i.update()
u'running'
>>> u'http://%s:6800/' % i.public_dns_name
u'http://ec2-54-224-86-173.compute-1.amazonaws.com:6800/'

and pointing your browser to this URL you must see the Scrapyd monitoring page.
Now you can schedule a spider run just by using

$ curl http://ec2-54-224-86-173.compute-1.amazonaws.com:6800/schedule.json -d project=myproject -d spider=spider1
{"status": "ok", "jobid": "70d1b1a6d6f111e0be5c001e648c5a52"}

You can find a copy of these scripts on Github ec2-scrapyd.

During these 3 weeks I learned many things, reading a lot of source code, looking for examples and discussing with other developers.
I can only say that I really enjoyed and was an incredible experience.
Thanks to all the Ubuntu development team and the community at large.

And this is not the end of the project, there are still many things to improve, if you want to help please contact me via this form. Also any questions or suggestions can be sent to Questions for Ubatar in Launchpad.

Now you can visit my site with native IPv6 connectivity.

If you want to know more about IPv6 you can start reading this overview

apt-get install tomcat6 tomcat6-admin

download and install the latest version of Solr

wget http://apache.cict.fr//lucene/solr/1.4.1/apache-solr-1.4.1.tgz
tar xvfz apache-solr-1.4.1.tgz
cd apache-solr-1.4.1
cp dist/apache-solr-1.4.1.war /var/lib/tomcat6/webapps/solr.war
cp -fr example/solr /var/lib/tomcat6/
chown -R tomcat6:tomcat6 /var/lib/tomcat6/solr

after install Solr you need to restart the tomcat6 service

/etc/init.d/tomcat6 restart

And voilà, Solr is running. Point your browser to http://localhost:8080/solr/admin this should show the Solr Admin interface.

• A preferences dialog to adjust size and position
• Two keyboard modes (normal and raw)
• Command line options (see –help)
• Some bug fixes

The next release will include support for Launchpad translations, save session to file and more keyboard modes (specific vim and emacs key bindings).

Thanks to Ivan Makfinsky for Fedora packaging and thanks to everyone who reported problems and made suggestions for improvement!

Mais bon pour le corriger, sans mettre à jour votre système Ubuntu 9.10, vous pouvez ouvrir un terminal et lancez la commande suivante

cd /usr/lib/totem/plugins/opensubtitles/
sudo sed -i 's/www/api/' opensubtitles.py

Ainsi, vous pouvez continuer à télécharger vos sous-titres sans problème.

A version of the toolkit for Linux can be downloaded from here, it includes build tools, utilities, examples,  and a device emulator. With some knowledge of Java programming and reading the API is easy to write small applications like this.

To install and run the application on the phone you have to download these files: AnotherCounter.jad and AnotherCounter.jar.

The source code is licensed under GPL and hosted on GitHub.

wget http://launchpad.net/mwbuttons/trunk/v0.2/+download/mwbuttons
chmod +x
./mwbuttons

La aplicación esta hosteada en Launchpad y la idea inicial fue solo para probar el módulo gconf de Python y el plugin de Launchpad para Bazaar.

This is just a modified version of the default theme in Ubuntu Karmic Koala. The main difference is that the minimize, maximize and close window bottons has been removed. They are only activated by mouseover.

It is useful for users who already know the position of the window buttons in GNOME and all the time use keyboard shortcuts to manage the windows. And especially useful on small screens like netbooks where there is not enough space avaliable to display redundant things.

The Human Simple theme can be downloaded from GNOME-Look http://gnome-look.org/content/show.php?content=118052

sudo modprobe ext4dev

to check the filesystems supported by the kernel we can do

cat /proc/filesystems

there should be a line with ext4dev.
Now, if we try to mount a formatted partition as ext4, will see that we can not do

sudo dmesg | tail

shows a line that says

EXT4-fs: sda2: not marked OK to use with test code.

to solve it we need to enable test_fs, an extended option for ext4 partitions

sudo tune2fs -E test_fs /dev/sda1

Now, we can mount it without problems

sudo mount -t ext4dev /dev/sda1 /mnt/disk

That’s all folks!

Note 1: replace sda1 by the appropiate device
Note 2: sorry for my english
