Dustin Kirkland: Learn Byobu in 10 minutes while listening to Mozart

Tue, 2014-08-12 12:44
If you're interested in learning how to more effectively use your terminal as your integrated devops environment, consider taking 10 minutes and watching this video while enjoying the finale of Mozart's Symphony No. 40Allegro Assai (part of which is rumored to have inspired Beethoven's 5th).

I'm often asked for a quick-start guide, to using Byobu effectively.  This wiki page is a decent start, as is the manpage, and the various links on the upstream website.  But it seems that some of the past screencast videos have had the longest lasting impressions to Byobu users over the years.
I was on a long, international flight from Munich to Newark this past Saturday with a bit of time on my hands, and I cobbled together this instructional video.    That recent international trip to Nuremberg inspired me to rediscover Mozart, and I particularly like this piece, which Mozart wrote in 1788, but sadly never heard performed.  You can hear it now, and learn how to be more efficient in command line environments along the way :-)


Enjoy!:-Dustin

Benjamin Kerensa: UbuConLA: Firefox OS on show in Cartagena

Tue, 2014-08-12 09:30

If you are attending UbuConLA I would strongly encourage you to check out the talks on Firefox OS and Webmaker. In addition to the talks, there will also be a Firefox OS workshop where attendees can go more hands on.

When the organizers of UbuConLA reached out to me several months ago, I knew we really had to have a Mozilla presence at this event so that Ubuntu Users who are already using Firefox as their browser of choice could learn about other initiatives like Firefox OS and Webmaker.

People in Latin America always have had a very strong ethos in terms of their support and use of Free Software and we have an amazingly vibrant community there in Columbia.

So if you will be anywhere near Universidad Tecnológica De Bolívar in Catagena, Columbia, please go see the talks and learn why Firefox OS is the mobile platform that makes the open web a first class citizen.

Learn how you can build apps and test them in Firefox on Ubuntu! A big thanks to Guillermo Movia for helping us get some speakers lined up here! I really look forward to seeing some awesome Firefox OS apps getting published as a result of our presence at UbuConLA as I am sure the developers will love what Firefox OS has to offer.

 

Feliz Conferencia!

Ronnie Tucker: Peppermint OS 5: Light, Refreshing Linux

Tue, 2014-08-12 08:00

The Peppermint OS is built around a concept that may be unique among desktop environments. It is a hybrid of traditional Linux desktop applications and cloud-based apps.

Using the Ice technology in the Peppermint OS is much like launching an app on an Android phone or tablet. For example, I can launch Google Docs, Gmail, Twitter, Yahoo Mail, YouTube, Pandora or Facebook as if they were self-contained apps on a mobile device — but these pseudo apps never need updating. Ice easily creates a menu entry to launch any website or application as if it were installed.

This innovative approach puts the latest release of Peppermint OS 5, which appeared in late June, well ahead of the computing curve. It brings cloud apps to the Linux desktop with the ease and flexibility of a Chromebook. It marries that concept to the traditional idea of having installed software that runs without cloud interaction.

Adam Stokes: Containerize juju’s local provider

Mon, 2014-08-11 23:05
Current approach

Juju’s existing providers(except manual) do not allow you to containerize the bootstrap node. However, in the manual provider this is possible using something like this in your environments.yaml file and setting the boostrap-host appropriately:

## https://juju.ubuntu.com/docs/config-manual.html manual: type: manual # bootstrap-host holds the host name of the machine where the # bootstrap machine agent will be started.org bootstrap-host: somehost.example.com # bootstrap-user specifies the user to authenticate as when # connecting to the bootstrap machine. If defaults to # the current user. # bootstrap-user: joebloggs # storage-listen-ip specifies the IP address that the # bootstrap machine's Juju storage server will listen # on. By default, storage will be served on all # network interfaces. # storage-listen-ip: # storage-port specifes the TCP port that the # bootstrap machine's Juju storage server will listen # on. It defaults to 8040 # storage-port: 8040

Cool, that will allow me to bootstrap juju on something other than my host machine. But, that machine needs to be configured appropriately for a non-interactive deployment (setting ssh keys, passwordless sudo, etc).

A different approach

In my particular case we wanted our Openstack Installer to be fully containerized from juju bootstrap to deploying of compute nodes. In order to achieve this we need to configure an existing container to be our bootstrap agent and still allow for our mixture of kvm/lxc environments for use within the Openstack deployment.

Walkthrough

Create a container named joojoo that will be used as our Juju bootstrap agent:

ubuntu@fluffy:~$ sudo lxc-create -t ubuntu -n joojoo

Update the container’s lxcbr0 to be on its own network:

ubuntu@fluffy:~$ cat <<-EOF | sudo tee /var/lib/lxc/joojoo/rootfs/etc/default/lxc-net USE_LXC_BRIDGE="true" LXC_BRIDGE="lxcbr0" LXC_ADDR="10.0.4.1" LXC_NETMASK="255.255.255.0" LXC_NETWORK="10.0.4.0/24" LXC_DHCP_RANGE="10.0.4.2,10.0.4.254" LXC_DHCP_MAX="253" EOF

Create the necessary character files for kvm support within lxc via mknod, also persist them through reboots.

ubuntu@fluffy:~$ cat <<-EOF | sudo tee /var/lib/lxc/joojoo/rootfs/etc/rc.local #!/bin/sh mkdir -p /dev/net || true mknod /dev/kvm c 10 232 mknod /dev/net/tun c 10 200 exit 0 EOF

Start the container

ubuntu@fluffy:~$ sudo lxc-start -n joojoo -d

Pre-install libvirt and uvtools

ubuntu@fluffy:~$ sudo lxc-attach -n joojoo -- apt-get update ubuntu@fluffy:~$ sudo lxc-attach -n joojoo -- apt-get install -qyf \ libvirt-bin uvtool uvtool-libvirt software-properties-common

Make sure our ubuntu user has the correct libvirtd group associated

ubuntu@fluffy:~$ sudo lxc-attach -n joojoo -- usermod -a -G libvirtd ubuntu Now that you have a containerized environment ready for Juju, lets test!

The LXC container should now be ready for a juju deployment. Lets use our Openstack Cloud Installer to test this setup. I want to make sure everything deploys into its appropriate containers/kvm instances and that I can still access the Horizon dashboard to deploy a compute instance.

First, ssh into your container, you can get the IP with the lxc-ls -f command:

ubuntu@fluffy:~$ sudo lxc-ls -f joojoo NAME STATE IPV4 IPV6 AUTOSTART ------------------------------------------- joojoo RUNNING 10.0.3.3 - NO ubuntu@fluffy:~$ ssh ubuntu@10.0.3.3

Within the container add our PPA and perform the installation:

ubuntu@joojoo:~$ sudo apt-add-repository ppa:cloud-installer/experimental ubuntu@joojoo:~$ sudo apt-add-repository ppa:juju/stable ubuntu@joojoo:~$ sudo apt update && sudo apt install cloud-installer ubuntu@joojoo:~$ sudo cloud-install

Note I’m using our experimental PPA for Openstack Cloud Installer which will be our next major release and will automate the previous steps for putting juju within a container.

This test I’m using the Single Install method, so select that and enter a Openstack password of your choice. Now sit back and wait for the installation to finish.

Recap

First we created a LXC container to be used as our entry point for juju to bootstrap itself too. This required some configuration changes to how the container will handle bridged connections along with making sure the character devices required by KVM are available.

Next we installed some pre-requisites for libvirt and uvtools.

From there we login to the newly created container, install, and run the Openstack Cloud Installer. This will install juju-core and lxc as dependencies along with automatically configuring lxc-net with our predefined lxc-net template, seen in the latest lxc-ls output (showing eth0, lxcbr0, and virbr0):

ubuntu@fluffy:~$ sudo lxc-ls -f NAME STATE IPV4 IPV6 AUTOSTART ------------------------------------------------------------------- joojoo RUNNING 10.0.3.3, 10.0.4.1, 192.168.122.1 - NO

Once the installer is finished we verify that our LXC container was able to facilitate the deployment of services in both LXC (nested) and KVM (also nested within LXC).

It’s a long list so here is the pastebin. What you’ll notice is that all machines/services are now bound to the 10.0.4.x network which is what was defined in the lxc-net configuration above. We have KVM’s running within our host container which also houses containers for the Openstack deployment.

Just to give a more visual representation of the setup:

Baremetal Machine - LXC Container - Runs juju bootstrap agent - KVM (machine 1) - Houses a bunch of LXC's for the openstack services - KVM (machine 2) - Houses nova-compute - KVM (machine 3) - Houses quantum-gateway Why is this a good thing? ubuntu@fluffy:~$ sudo lxc-stop -n joojoo ubuntu@fluffy:~$ sudo lxc-destroy -n joojoo

And it’s like it never happened …

Acknowledgements

Thanks to a colleague, Robert Ayres, who provided the necessary information for getting KVM to run within an LXC container.

Destino: Ubuconla '14
Y tras meses esperando a que llegue la fecha, a falta de pocos días nos sorprende la huelga de pilotos de la aerolínea TAP, afectando sólo al día de nuestro vuelo :S

Ups! :SReprogramando la salida con TAP y un enlace con LAN, no nos queda otra que cancelar los billetes del ALSA y otro enlace de Avianca. Y tras largas gestiones y unos cuantos euros tirados a la basura, todo queda solucionado. En fin, pequeños gajes de viajar.


El resumen perfecto del viaje de ida es:

Asturies ➠ Bilbao ✈ Lisboa ✈ São Paulo ✈ Bogotá ✈ Cartagena de Indias
=
42 Horas contínuas de bus + aeropuertos + aviones
=
Jetlag3

Literalmente derrengaos
Y con sensación de Willy Fog...:PY un par de vuelos con las aerolíneas TAP y Avianca sirvieron para demostrar que Linux (una vez más) está en más sitios de los que pensamos ;)


Por fin en tierras colombianas, ¡Comienza la aventura! :D Pero eso será ya parte de otros posts.

Ubuntu Scientists: Who We Are: Willem Ligtenberg,A Member

Mon, 2014-08-11 14:17

I am Willem Ligtenberg.
I have studied Biomedical Engineering and later specialized myself in bioinformatics, which is also
known as computational biology. More specifically, I specialized myself in biomodeling and bioinformatics.
During my PhD thesis I investigated the use of graph theoretic approaches in biology.
I used graph algorithms in combination with machine learning algorithms to reverse engineer gene regulatory networks. If you are interested you can have a
read here: http://www.biomedcentral.com/1471-2105/13/281

During this I used a lot of Python and a bit of R for the statistics. I also took a course on
biostatistics for PhD students and although the course was given using Statgraphics, I did using R.
Which the tutors thought was fine, but it was not their expertise. However, they did give me the
e-mail address of a collegue of theirs who used R as well.

Fast-forward a couple of years, and currently I am working as a consultant for Open Analytics
(http://www.openanalytics.eu), which is a company that helps with the data analysis from start to finish. As the name suggests
the company believes in openness and therefore focusses on the use of (fibre/libre) open source software (FLOSS).
The FLOSS aspect of the company was a big plus for me, since I have been using Ubuntu since Warty (2004).
For the data analysis part we mainly use R, but we will use other languages if they are more
appropriate. So I still get to use Python now and then.

I have written and contributed to a few R packages that are on Bioconductor: (reactome.db,
the a4 packages and MLP). I am currenty working on an Object Relational Mapper in R, which
I hope to publish soon. Feel free to reach out to me if you want to know more about data analysis
using open source software, specifically bioinformatics and databases.

Cheers,

Willem Ligtenberg

Valorie Zimmerman: Randa Meetings sprint: KDE Frameworks Cookbook progress

Mon, 2014-08-11 14:06
We groaned and suffered with the up-and-down network, and had to abandon our plan to write and edit the book on Booki at Flossmanuals. So we began to create text files on Kate or Kwrite, but how to share our work?

The best answer seemed to be a git repository, and our success began there. Once created, we consulted again and again with the Frameworks developers in the room across the hall, and brainstormed and wrote, and even created new tools (Mirko). Our repo is here: kde:scratch/garg/book. If you want to see the live code examples, you will need this tool: https://github.com/endocode/snippetextractor .

I'm so happy with what we have so far! The texts are just great, and the code examples will be updated as they are updated in their repositories. So if people planning a booth at a Qt Contributor Conference, for instance, wanted to print up some copies of the book, it will be completely up-to-date. Our goal is committing every part of the book so that it can be auto-fetched for reading as an epub, pdf, text file or printed as a book.

It is a tremendous help to be in the same place. Thank you KDE community for sending me here, all the way from Seattle. Thank you for bringing all the other developers here as well. We are eating well, meeting, coding, writing, walking, drinking coffee and even some Free Beer, and sometimes sleeping too. Mario brings around a huge box of chocolate every night. We're all going to arrive home somewhat tired from working so hard, and somewhat fat from eating so well!

Stuart Langridge: Reverse SSH tunnels

Sun, 2014-08-10 22:49

My dad’s got a computer. Infrequently, it goes wrong and I need to fix it. Slightly more frequently, it doesn’t go wrong but it does something which is confusing, and I need to try to fix it until I realise what the confusing thing was and then either fix that or explain it. So, being able to connect to his machine is useful.

His ADSL router, from TalkTalk1, allows one to set up a port forward2 so that I can connect to his external IP and have that routed to port 22 on his machine, thus allowing me SSH access, and with SSH I can do everything else3. However, that router also controls the DHCP addresses for things on the network, and it does not always give the same address out to the same machine. So, every now and again, it’ll give his machine a different IP, and then the port forward stops working.4

So, after mithering about this a bit, Daviey Walker suggested5 that I use a reverse SSH tunnel. That is to say: I have his machine ssh into one of mine, and then port forward a port on my machine back along the SSH tunnel to port 22 on his machine, meaning that I can ssh into it and don’t have to care about IPs or anything.

This was a dead clever idea. It relies on me having a machine which is sshable from the outside world, but I do, so that’s OK.

Obviously, something needs to set the tunnel up. So, first I set things up so that his machine could ssh into mine with key authentication and without a password needed (see ssh-copy-id or a guide for that), and then I wrote this little script:

#!/bin/bash createTunnel() { date ssh -N -o BatchMode=yes -R 9102:localhost:22 mylogin@mysshablemachine if [[ $? -eq 0 ]]; then echo Tunnel created successfully else echo An error occurred creating a tunnel. RC was $? fi } /bin/pidof ssh > /dev/null if [[ $? -ne 0 ]]; then echo Creating new tunnel connection createTunnel fi

which creates this ssh tunnel connection. There’s a hack there: it assumes that if there’s an ssh process, it’s our ssh process. If you regularly ssh from the box you’re doing this on, you’ll want to do something cleverer. In this case I don’t, so I keep it easy. Couple of little tricks in the script: there’s a date command, so the output mentions when this happened, which is useful for the log file in the next bit (and this is also why the script generates no output if the tunnel is already up). Secondly, -o BatchMode=yes in the ssh options means that it’ll instantly fail if you haven’t got key auth set up right, rather than hanging forever waiting for a password, and it’ll send server keepalives every 300 seconds and kill the connection if they break, which means that if the connection hangs but doesn’t terminate, it’ll get terminated. This is what we want, because we want some monitoring process to restart the tunnel if it dies. There are all sorts of clever ways to do this: upstart, systemd, whatever6, but I just put this line in the crontab7:

*/1 * * * * /path/to/above/script.sh >> /path/to/tunnel.log 2>&1

which just reruns the above script every minute and sticks any output into a logfile so if it’s not working I can, at a push, ask dad to read the logfile. Inefficient and low-budget, but it works. So once all this is set up, I can, from my sshable machine, do ssh -p 9012 dadlogin@localhost and I then get to log in to his machine. Then I can fix it. And never deal with his horrid router’s horrid web UI ever again.

  1. a Huawei HG533 with the most annoying web config UI I’ve ever seen ever, which gets even more annoying if you try and control it from curl because it’s all JavaScript-dependent. Why? You are a router, not gmail! Grrrr!
  2. hooray
  3. hooray
  4. Also, I really really don’t like static IPs, so I don’t want to configure it with one.
  5. that is, I was mithering about it. Not Daviey.
  6. not /etc/init.d though. This is a user-level process. It should not be being run by system-level stuff. System level belongs to apt.
  7. a file which defines jobs to be run at specific times; it’s like a super-techie Scheduled Tasks wizard, and it usefully will run things even when you’re not logged in. You can edit yours from the command line with crontab -e.

Diego Turcios: How I miss you Synaptic!

Sun, 2014-08-10 01:03
Several years  have passed since we saw the Synaptic included in Ubuntu. You can found reasons here .
So in a clear english the reason was to have a better add/remove program for users. A friendly application. The explanation sounds good, I didn't complain about that, until right now. Ubuntu has change a lot, it's really a friendly user OS.

I have use CLI when necessary, but today I couldn't believe it.
I'm a Google Chrome user, I know you will tell me it's not open source or I should use Chromium or FF. But no. I'm a user of Google Chrome, and many people also prefer Chrome over Chromium, so why it should be quite complex remove it? If Ubuntu wants to be more friendly user why you should use the terminal for removing one of the most popular web browsers? I could understand if is a browser few people use, a good reason. But not a popular browser, Chrome is one of the most popular browsers on the world!

A screen shot of the Ubuntu Software Center, trying to remove Google Chrome.
No results, not even a message telling no results found. This is not a friendly user application!



So, I decided to check Synaptic to see if it was possible to remove Google Chrome yes it's so simple.












So please tell me, I'm wrong or I'm right. What's your opinion?

Canonical Design Team: Ubuntu 14.10 wallpapers – we needs ‘em!

Fri, 2014-08-08 09:12

Verónica Sousa’s Cul de sac

Ubuntu was once described to me by a wise(ish ;) ) man as a train that was leaving whether you’re on it or not. That’s the beauty of a 6 month release cycle. As many of you will already know, each release we include photos and illustrations produced by community members. We ask that you submit your images using free photo sharing site Flickr and that you limit your images this time to 2. The group won’t let you submit more than that but if you change your mind after you’ve submitted, fear not, simply remove one and it’ll let you add another.

As with previous submissions processes we’ve run, and in conjunction with the designers at Canonical we’ve come up with the following tips for creating wallpaper images.

  1. Images shouldn’t be too busy and filled with too many shapes and colours, a similar tone throughout is a good rule of thumb.
  2. A single point of focus, a single area that draws the eye into the image, can also help you avoid something too cluttered.
  3. The left and top edges are home to Ubuntu’s Launcher and Panel so be careful to consider how your images look in place so as not to clash with the user interface. Try them out on your own desktop, see how they feel.
  4. Try your image at different aspect ratios to make sure something important isn’t cropped out on smaller/ larger screens at different resolutions.
  5. Take a look at the wallpapers guidance on the Ubuntu Wiki regarding the size of images. Our target resolution is 2560 x 1600.
  6. Break all the rules except the resolution one! :D

To shortlist from this collection we’ll be going to the contributors whose images were selected last time around to act as our selection judges. In doing this we’ll hold a series of public IRC meetings on Freenode in #1410wallpaper to discuss the selection. In those sessions we’ll get the selection team to try out the images on their own Ubuntu machines to see what they look like on a range of displays and resolutions.

Anyone is welcome to come to these sessions but please keep in mind that an outcome is needed from the time that people are volunteering and there’s usually a lot of images to get through so we’d appreciate it if there isn’t too much additional debate.

Based on the Utopic release schedule, I think our schedule for this cycle should look like this:

  • 08/08/14 – Kick off 14.10 wallpaper submission process.
  • 22/08/14 – First get together on #1410wallpaper at 19:30 GMT.
  • 29/08/14 – Submissions deadline at 18:00 GMT – Flickr group will be locked and the selection process will begin.
  • 09/09/14 – Deliver final selection in zip format to the appropriate bug on Launchpad.
  • 11/09/14 – UI freeze for latest version of Ubuntu with our fantastic images in it!

As always, ping me if you have any questions, I’ll be lurking in #1410wallpaper on freenode or leave a question in the Flickr group for wider discussion, that’s probably the fastest way to get an answer to a question.

I’ll be posting updates on our schedule here from time to time but the Flickr group will serve as our hub.

Happy snapping and scribbling and on behalf of the community, thanks for contributing to Ubuntu!

Edubuntu Long-Term Support Edubuntu 12.04.5 LTS is the fifth Long Term Support (LTS) version of Edubuntu as part of Edubuntu 12.04's 5 years support cycle. Edubuntu's Fifth LTS Point Release The Edubuntu team is proud to announce the release of Edubuntu 12.04.5. This is the last of five LTS point releases for this LTS lifecycle. The point release includes all the bug fixes and improvements that have been applied to Edubuntu 12.04 LTS since it has been released. It also includes updated hardware support and installer fixes. If you have an Edubuntu 12.04 LTS system and have applied all the available updates, then your system will already be on 12.04.5 LTS and there is no need to re-install. For new installations, installing from the updated media is recommended since it will be installable on more systems than before and will require drastically less updates than installing from the original 12.04 LTS media. This release ships with a backported kernel and X stack. This enables users to make use of more recently released hardware. Current users of Edubuntu 12.04 won't be automatically updated to this back-ported stack, you can however manually install the packages as well.
  • Information on where to download the Edubuntu 12.04.5 LTS media is available from the Downloads page.
  • We do not ship free Edubuntu discs at this time, however, there are 3rd party distributors available who ship discs at reasonable prices listed on the Edubuntu Martketplace
Although Edubuntu 10.04 systems will ask for upgrade to 12.04.5, it's not an officially supported upgrade path. Testing however indicated that this usually works if you're ready to make some minor adjustments afterwards. To ensure that the Edubuntu 12.04 LTS series will continue to work on the latest hardware as well as keeping quality high right out of the box, we will release another point release before the next long term support release is made available in 2014. More information is available on the release schedule page on the Ubuntu wiki. The release notes are available from the Ubuntu Wiki. Thanks for your support and interest in Edubuntu!
