A few years ago when our fine friends on the kernel team introduced the idea of the "hardware enablement" (HWE) kernel, those of us in the Cloud world looked at it as curiosity. We thought that by in large, the HWE kernel would not be needed or wanted for Virtual Cloud instances.

And we were wrong.

So wrong in fact, that the HWE kernel has found its way into the Vagrant Cloud Images, VMware's vCHS, and Google's Compute engine as the default kernel for the Certified Images. The main reason for these requests is that virtual hardware moves at a fairly quick pace. Unlike traditional hardware, Virtual Hardware can be fixed and patched at the speed that software can be deployed.

The feedback in regards to Azure has been the same: users and Microsoft has asked for the HWE kernel consistently. Microsoft has validated that the HWE kernel (3.16) running Ubuntu 14.04 on Windows Azures passes their validation testing. In our testing, we have validated that the 3.16 kernel works quite well in Azure.

For Azure users, using the 3.16 HWE kernel brings SMB 2.1 copy file support and updates LSI drivers.

Therefore, starting with the latest Windows Azure image [1], all the Ubuntu 14.04 images will track the latest hardware enablement kernel. That means that all the goodness in Ubuntu 14.10's kernel will be the default for 14.04 users launching our official images on Windows Azure.

If you want to install the LTS kernel on your existing instance(s), simply run:

  • sudo apt-get update
  • sudo apt-get install linux-image-virtual-lts-utopic linux-lts-utopic-cloud-tools-common walinuxagent
  • sudo reboot

Gratuitous picture of my pets, the day after we rescued them


Some Background

In March 2014, when I first started looking after MAAS as a product manager, I raised a minor feature request in Bug #1287224, noting that the random, 5-character hostnames that MAAS generates are not ideal. You can't read them or pronounce them or remember them easily. I'm talking about hostnames like: sldna, xwknd, hwrdz or wkrpb. From that perspective, they're not very friendly. Certainly not very Ubuntu.

We're not alone, in that respect. Amazon generates forgettable instance names like i-15a4417c, along with most virtual machine and container systems.

So I proposed a few different ways of automatically generating those names, modeled mostly after Ubuntu's beloved own code naming scheme -- Adjective Animal. To get the number of combinations high enough to model any reasonable MAAS user, though, we used Adjective Noun instead of Adjective Animal.

I collected a Adjective list and a Noun list from a blog run by moms, in the interest of having a nice, soft, friendly, non-offensive source of words.

For the most part, the feature served its purpose. We now get memorable, pronounceable names. However, we get a few odd balls in there from time to time. Most are humorous. But some combinations would prove, in fact, to be inappropriate, or perhaps even offensive to some people.

Accepting that, I started thinking about other solutions.

In the mean time, I realized that Docker had recently launched something similar, their NamesGenerator, which pairs an Adjective with a Famous Scientist's Last Name (except they have explicitly blacklisted boring_wozniak, because "Steve Wozniak is not boring", of course!).


Similarly, Github itself now also "suggests" random repo names.



I liked one part of the Docker approach better -- the use of proper names, rather than random nouns.

On the other hand, their approach is hard-coded into the Docker Golang source itself, and not usable or portable elsewhere, easily.

Moreover, there's only a few dozen Adjectives (57) and Names (76), yielding only about 4K combinations (4332) -- which is not nearly enough for MAAS's purposes, where we're shooting for 16M+, with minimal collisions (ie, covering a Class A network).

Introducing the PetName Libraries

MAAS was already pretty good on Adjectives (about 1,300). But I decided to scrap the Nouns list, and instead build a Names list. I started with Last Names (like Docker), but instead focused on First Names, and built a list of about 2,000 names from public census data.

The combination actually works pretty well! While smelly-Susan isn't particularly charming, it's certainly not an ad hominem attack targeted at any particular Susan! That 1,300 x 2,000 gives us well over 2 million unique combinations.

Moreover, I also thought about how I could actually make it infinitely extensible... The simple rules of English allow Adjectives to modify Nouns, while Adverbs can recursively modify other Adverbs or Adjectives.   How convenient!

So I built a word list of Adverbs (3,600) as well, and added support for specifying the "number" of words in a PetName.
  1. If you want 1, you get a random Name 
  2. If you want 2, you get a random Adjective followed by a Name 
  3. If you want 3 or more, you get N-2 Adverbs, an Adjective and a Name 
Oh, and the separator is now optional, and can be any character or string, with a default of a hyphen, "-".

Note:
  • 3 words will generate nearly 10 billion unique combos -- more than a 32-bit unique space (232)
  • And 5 words will nearly cover 64-bit space (264).

Shell

So once the algorithm was spec'd out, I built and packaged a simple shell utility and text word lists, called petname, which are published at:
The packages are already in Ubuntu 15.04 (Vivid). On any other version of Ubuntu, you can use the PPA:

$ sudo apt-add-repository ppa:petname/ppa
$ sudo apt-get update

And:
$ sudo apt-get install petname
$ petname
itchy-Marvin
$ petname -w 3
listlessly-easygoing-Radia
$ petname -s ":" -w 5
onwardly:unflinchingly:debonairly:vibrant:Chandler

Python

That's only really useful from the command line, though. In MAAS, we'd want this in a native Python library. So it was really easy to create python-petname, source now published at:
The packages are already in Ubuntu 15.04 (Vivid). On any other version of Ubuntu, you can use the PPA:

$ sudo apt-add-repository ppa:python-petname/ppa
$ sudo apt-get update

And:
$ sudo apt-get install python-petname
$ python-petname
flaky-Megan
$ python-petname -w 4
mercifully-grimly-fruitful-Salma
$ python-petname -s "" -w 2
filthyLaurel

Using it in your own Python code looks as simple as this:

$ python
⟫⟫⟫ import petname
⟫⟫⟫ foo = petname.PetName(3, "_")
⟫⟫⟫ print(foo)

Golang


In the way that NamesGenerator is useful to Docker, I though a Golang library might be useful for us in LXD (and perhaps even usable by Docker or others too), so I created:
The packages are already in Ubuntu 15.04 (Vivid). On any other version of Ubuntu, you can use the PPA:

$ sudo apt-add-repository ppa:golang-petname/ppa
$ sudo apt-get update

And:
$ sudo apt-get install golang-petname
$ golang-petname

$ golang-petname -words=1
Vivian
$ golang-petname -separator="|" -words=10
snobbily|oracularly|contemptuously|discordantly|lachrymosely|afterwards|coquettishly|politely|elaborate|Samir

Using it in your own Golang code looks as simple as this:

package main
import (
"fmt"
"math/rand"
"time"
"github.com/dustinkirkland/golang-petname"
)
func main() {
flag.Parse()
rand.Seed(time.Now().UnixNano())
fmt.Println(petname.PetName(2, ""))
}

With the recent introduction of Snappy Ubuntu, there are now several different ways to extend and update (apt-get vs. snappy) multiple flavors of Ubuntu (Core, Desktop, and Server).

We've put together this matrix with a few examples of where we think Traditional Ubuntu (apt-get) and Transactional Ubuntu (snappy) might make sense in your environment.  Note that this is, of course, not a comprehensive list.

Ubuntu Core
Ubuntu Desktop
Ubuntu Server
Traditional apt-get
Minimal Docker and LXC imagesDesktop, Laptop, Personal WorkstationsBaremetal, MAAS, OpenStack, General Purpose Cloud Images
Transactional snappy
Minimal IoT Devices and Micro-Services Architecture Cloud ImagesTouch, Phones, TabletsComfy, Human Developer Interaction (over SSH) in an atomically updated environment

I've presupposed a few of the questions you might ask, while you're digesting this new landscape...

Q: I'm looking for the smallest possible Ubuntu image that still supports apt-get...
A: You want our Traditional Ubuntu Core. This is often useful in building Docker and LXC containers.

Q: I'm building the next wearable IoT device/drone/robot, and perhaps deploying a fleet of atomically updated micro-services to the cloud...
A: You want Snappy Ubuntu Core.

Q: I want to install the best damn Linux on my laptop, desktop, or personal workstation, with industry best security practices, 30K+ freely available open source packages, freely available, with extensive support for hardware devices and proprietary add-ons...
A: You want the same Ubuntu Desktop that we've been shipping for 10+ years, on time, every time ;-)

Q: I want that same converged, tasteful Ubuntu experience on your personal, smart devices like my Phones and Tablets...
A: You want Ubuntu Touch, which is a very graphical human interface focused expression of Snappy Ubuntu.

Q: I'm deploying Linux onto bare metal servers at scale in the data center, perhaps building IaaS clouds using OpenStack or PaaS cloud using CloudFoundry? And I'm launching general purpose Linux server instances in public clouds (like AWS, Azure, or GCE) and private clouds...
A: You want the traditional apt-get Ubuntu Server.

Q: I'm developing and debugging applications, services, or frameworks for Snappy Ubuntu devices or cloud instances?
A: You want Comfy Ubuntu Server, which is a command line human interface extension of Snappy Ubuntu, with a number of conveniences and amenities (ssh, byobu, manpages, editors, etc.) that won't be typically included in the minimal Snappy Ubuntu Core build. [*Note that the Comfy images will be available very soon]

Forget about The Year of the Linux Desktop...This is The Year of the Linux Countertop!

I'm talking about Linux on every form of Internet-connected embedded devices.  The Internet-of-Things is already upon us.  Sensors, smart watches, TVs, thermostats, security cameras, drones, printers, routers, switches, robots -- you name it.  

And with that backdrop, we are thrilled to introduce Snappy Ubuntu for Devices.  Ubuntu is now a possibility, on almost any device, anywhere.  Now that's exciting!

This is the same Snappy Ubuntu, with its atomic, transactional updates that we launched on each major public cloud last month -- extended and updated for 64-bit Intel, AMD and ARM devices.


Now, if you want a detailed, developer's look at building a Snappy Ubuntu image and running it on a BeagleBone, you're in luck!  I shot this little instructional video (using Cheese, GTK-RecordMyDesktop, and OpenShot).  Enjoy!


A transcript of the video follows...


  1. What is Snappy Ubuntu?
    • A few weeks ago, we introduced a new flavor of Ubuntu that we call “Snappy” -- an atomically, transactionally updated Operating System -- and showed how to launch, update, rollback, and install apps in cloud instances of Snappy Ubuntu in Amazon EC2, Microsoft Azure, and Google Compute Engine public clouds.
    • And now we’re showing how that same Snappy Ubuntu experience is the perfect operating system for today’s Cambrian Explosion of smart devices that some people are calling “the Internet of Things”!
    • Snappy Ubuntu Core bundles only the essentials of a modern, appstore powered Linux OS stack and hence leaves room both in size as well as flexibility to build, maintain and monetize very own device solution without having to care about the overhead of inventing and maintaining your own OS and tools from scratch. Snappy Ubuntu Core comes right in time for you to put your very own stake into stake into still unconquered worlds of things
    • We think you’ll love Snappy on your smart devices for many of the same reasons that there are already millions of Ubuntu machine instances in hundreds of public and private clouds, as well as the millions of your own Ubuntu desktops, tablets, and phones!
  2. Unboxing the BeagleBone
    • Our target hardware for this Snappy Ubuntu demo is the BeagleBone Black -- an inexpensive, open platform for hardware and software developers.
    • I paid $55 for the board, and $8 for a USB to TTL Serial Cable
    • The board is about the size of a credit card, has a 1GHz ARM Cortex A8 processor, 512MB RAM, and on board ethernet.
    • While Snappy Ubuntu will run on most any armhf or amd64 hardware (including the Intel NUC), the BeagleBone is perhaps the most developer friendly solution.
  3. The easiest way to get your Snappy Ubuntu running on your Beaglebone
    • The world of Devices has so many opportunities that it won’t be possible to give everyone the perfect vertical stack centrally. Hence Canonical is trying to enable all of you and provide you with the elements that get you started doing your innovation as quickly as possible. Since there will be many devices that won’t need a screen and input devices, we have developed “webdm”. webdm gives you the ability to manage your snappy device and consume apps without any development effort.
    • To installl you simply download our prebuilt WEB .img and dd it to your sd card.
    • After that all you ahve to do is to connect your beaglebone to a DHCP enabled local network and power it on.
    • After 1-2 minutes you go to http://webdm.local:8080 and can get onto installing apps from the snappy appstore without any further effort
    • Of course, we are still in beta and will continue give you more features and a greater experience over time; we will not only make the UI better, but also work on various customization options that allow you to deliver your own app store powered product without investing your development resources in something that already got solved.
  4. Downloading Snappy and writing to an sdcard
    • Now we’re going to build a Snappy Ubuntu image to run on our device.
    • Soon, we’ll publish a library of Snappy Ubuntu images for many popular devices, but for this demo, we’re going to roll our own using the tool, ubuntu-device-flash.
    • ls -halF mysnappy.img
    • sudo dd if=mysnappy.img of=/dev/mmblk0 bs=1M oflag=dsync
  5. Hooking up the BeagleBone
    • Insert the microsd card
    • Network cable
    • USB debug
    • Power/USB
  6. Booting Snappy and command line experience
    • Okay, so we’re ready for our first boot of Snappy!
    • Let’s attach to the USB/serial console using screen
    • Now, I’ll attach the power, and if you watch very carefully, you might get to see some a few boot messages.
    • snappy help
    • ifconfig
    • ssh ubuntu@10.0.0.105
  7. WebDM experience
    • snappy info
    • Shows we have the webdm framework installed
    • point browser to http://10.0.0.105:8080
    • Configuration
    • Store
  8. Conclusion
    • Hey how cool is that!  Snappy Ubuntu running on devices :-)
    • I’ve spent plenty of time and money geeking out over my Nest and Dropcam and Netatmo and WeMo lightswitches, playing with their APIs and hooking them up to If-This-Then-That.
    • But I’m really excited about a world where those types of devices are as accessible to me as my Ubuntu servers and desktops!
    • And from what I’ve shown you here, with THIS, I think we can safely say that that we’ve blown right past the year of the Linux desktop.
    • This is the year of the Linux countertop!

Cheers,
Dustin

For a long time now Canonical has provided Ubuntu LoCo Teams with material to use in the promotion of Ubuntu. This has come in the form of CDs and DVDs for Ubuntu releases, as well as conference packs for booths and shows.

We’ve also been sent several packages, when requested by an Ubuntu Member, to LoCo Teams for their own events, such as release parties or global jams.

Ubuntu Mauritius Team 14.10 Global Jam

This cycle we are extending this offer to any LoCo team that is hosting an in-person Global Jam event. It doesn’t matter how many people are going, or what you’re planning on doing for your jam. The Jam Packs will include DVDs, stickers, pens and other giveaways for your attendees, as well as an Ubuntu t-shirt for the organizers (or as a giveaway, if you choose).

Since there is only a few weeks before Global Jam weekend, and these will be shipped from London, please take your country’s customs process into consideration before ordering. Countries in North America and Europe shouldn’t have a problem, but if you’ve experienced long customs delays in the past please consider waiting and making your request for the next Global Jam.

To get an Ubuntu Global Jam Pack for your event, all you need to do is the following:

  • Register you Global Jam event on the LoCo Team Portal
    • Your event must be in-person, and have a venue associated with it
  • Fill out the community donation request form
    • Include a link to your LoCo Team Portal event in your request
  • Promote your event, before and after
    • Blog about it, post pictures, and share your excitement on social media
      • Use the #ubuntu hashtag when available

You can find all kinds of resources, activities and advice for running your Global Jam event on the Ubuntu Wiki, where we’ve collected the cumulative knowledge from all across the community over many years. And you can get live help and advice any time on the #ubuntu-locoteams IRC channel on Freenode.

Snappy Launches


When we launched Snappy, we introduced it on Microsoft Azure [1], Google’s GCE [2], Amazon’s AWS [3] and our KVM images [4]. Immediately our developers were asking questions like, “where’s the Vagrant images”, which we launched yesterday [5].

The one final remaining question was “where are the images for <insert hypervisor>”. We had inquiries about Virtualbox, VMware Desktop/Fusion, interest in VMware Air, Citrix XenServer, etc.

OVA to the rescue

OVA is an industry standard for cross-hypervisor image support. The OVA spec [6] allows you to import a single image to:

  • VMware products
    • ESXi
    • Desktop
    • Fusion
    • VSphere
  • Virtualbox
  • Citrix XenServer
  • Microsoft SCVMM
  • Red Hat Enterprise Virtualization
  • SuSE Studio
  • Oracle VM

Okay, so where can I get the OVA images?

To get the latest OVA image, you can get it from here [7]. From there, you will need to follow your hypervisor instructions on importing OVA images. 

Or if you want a short URL, http://goo.gl/xM89p7

I am pleased to announce initial Vagrant images [1, 2]. These images are bit-for-bit the same as the KVM images, but have a Cloud-init configuration that allows Snappy to work within the Vagrant workflow.

Vagrant enables a cross platform developer experience on MacOS, Windows or Linux [3].

Note: due to the way that Snappy works, shared file systems within Vagrant is not possible at this time. We are working on getting the shared file system support enabled, but it will take us a little bit to get going.

If you want to use Vagrant packaged in the Ubuntu archives, in a terminal run::

  • sudo apt-get -y install vagrant
  • cd <WORKSPACE>
  • vagrant box add snappy http://goo.gl/6eAAoX
  • vagrant init snappy
  • vagrant up
  • vagrant ssh
If you use Vagrant from [4] (i.e Windows, Mac or install the latest Vagrant) then you can run:
  • vagrant init ubuntu/ubuntu-core-devel-amd64
  • vagrant up
  • vagrant ssh

These images are a work in progress. If you encounter any issues, please report them to "snappy-devel@lists.ubuntu.com" or ping me (utlemming) on Launchpad.net

Whenever a user downloads Ubuntu from our website, they are asked if they would like to make a donation, and if so how they want their money used. When the “Community” option is chosen, that money is made available to members of our community to use in ways that they feel will benefit Ubuntu.

I’m a little late getting this report published, but it’s finally done. You can read the report here: https://docs.google.com/a/canonical.com/document/d/1HrBqGjqKe-THdK7liXFDobDU2LVW9JWtKxoa8IywUU4/edit#heading=h.yhstkxnvuk7s

We pretty consistently spend less than we get in each quarter, which means we have money sitting around that could be used by the community. If you want to travel to an event, would like us to sponsor an event, need hardware for development or testing, or anything else that you feel will make Ubuntu the project and the community better, please go and fill out the request form.

There’s a saying in American political debate that is as popular as it is wrong, which happens when one side appeals to our country’s democratic ideal, and the other side will immediately counter with “The United States is a Republic, not a Democracy”. I’ve noticed a similar misunderstanding happening in open source culture around the phrase “meritocracy” and the negatively-charged “oligarchy”. In both cases, though, these are not mutually exclusive terms. In fact, they don’t even describe the same thing.

Authority

One of these terms describes where the authority to lead (or govern) comes from. In US politics, that’s the term “republic”, which means that the authority of the government is given to it by the people (as opposed to divine-right, force of arms, of inheritance). For open source, this is where “meritocracy” fits in, it describes the authority to lead and make decisions as coming from the “merit” of those invested with it. Now, merit is hard to define objectively, and in practice it’s the subjective opinion of those who can direct a project’s resources that decides who has “merit” and who doesn’t. But it is still an important distinction from projects where the authority to lead comes from ownership (either by the individual or their employer) of a project.

Enfranchisement

History can easily provide a long list of Republics which were not representative of the people. That’s because even if authority comes from the people, it doesn’t necessarily come from all of the people. The USA can be accurately described as a democracy, in addition to a republic, because participation in government is available to (nearly) all of the people. Open source projects, even if they are in fact a meritocracy, will vary in what percentage of their community are allowed to participate in leading them. As I mentioned above, who has merit is determined subjectively by those who can direct a project’s resources (including human resource), and if a project restricts that to only a select group it is in fact also an oligarchy.

Balance and Diversity

One of the criticisms leveled against meritocracies is that they don’t produce diversity in a project or community. While this is technically true, it’s not a failing of meritocracy, it’s a failing of enfranchisement, which as has been described above is not what the term meritocracy defines. It should be clear by now that meritocracy is a spectrum, ranging from the democratic on one end to the oligarchic on the other, with a wide range of options in between.

The Ubuntu project is, in most areas, a meritocracy. We are not, however, a democracy where the majority opinion rules the whole. Nor are we an oligarchy, where only a special class of contributors have a voice. We like to use the term “do-ocracy” to describe ourselves, because enfranchisement comes from doing, meaning making a contribution. And while it is limited to those who do make contributions, being able to make those contributions in the first place is open to anybody. It is important for us, and part of my job as a Community Manager, to make sure that anybody with a desire to contribute has the information, resources, and access to to so. That is what keeps us from sliding towards the oligarchic end of the spectrum.

As promised last week, we're now proud to introduce Ubuntu Snappy images on another of our public cloud partners -- Google Compute Engine.
In the video below, you can join us walking through the instructions we have published here.
Snap it up!

A couple of months ago, I re-introduced an old friend -- Ubuntu JeOS (Just enough OS) -- the smallest, (merely 63MB compressed!) functional OS image that we can still call “Ubuntu”.  In fact, we call it Ubuntu Core.

That post was a prelude to something we’ve been actively developing at Canonical for most of 2014 -- Snappy Ubuntu Core!  Snappy Ubuntu combines the best of the ground-breaking image-based Ubuntu remix known as Ubuntu Touch for phones and tablets with the base Ubuntu server operating system trusted by millions of instances in the cloud.

Snappy introduces transactional updates and atomic, image based workflows -- old ideas implemented in databases for decades -- adapted to Ubuntu cloud and server ecosystems for the emerging cloud design patterns known as microservice architectures.

The underlying, base operating system is a very lean Ubuntu Core installation, running on a read-only system partition, much like your iOS, Android, or Ubuntu phone.  One or more “frameworks” can be installed through the snappy command, which is an adaptation of the click packaging system we developed for the Ubuntu Phone.  Perhaps the best sample framework is Docker.  Applications are also packaged and installed using snappy, but apps run within frameworks.  This means that any of the thousands of Docker images available in DockerHub are trivially installable as snap packages, running on the Docker framework in Snappy Ubuntu.

Take Snappy for a Drive


You can try Snappy for yourself in minutes!

You can download Snappy and launch it in a local virtual machine like this:

$ wget http://cdimage.ubuntu.com/ubuntu-core/preview/ubuntu-core-alpha-01.img
$ kvm -m 512 -redir :2222::22 -redir :4443::443 ubuntu-core-alpha-01.img

Then, SSH into it with password 'ubuntu':

$ ssh -p 2222 ubuntu@localhost

At this point, you might want to poke around the system.  Take a look at the mount points, and perhaps try to touch or modify some files.


$ sudo rm /sbin/init
rm: cannot remove ‘/sbin/init’: Permission denied
$ sudo touch /foo

touch: cannot touch ‘foo’: Permission denied
$ apt-get install docker
apt-get: command not found

Rather, let's have a look at the new snappy package manager:

$ sudo snappy --help



And now, let’s install the Docker framework:

$ sudo snappy install docker

At this point, we can do essentially anything available in the Docker ecosystem!

Now, we’ve created some sample Snappy apps using existing Docker containers.  For one example, let’s now install OwnCloud:

$ sudo snappy install owncloud

This will take a little while to install, but eventually, you can point a browser at your own private OwnCloud image, running within a Docker container, on your brand new Ubuntu Snappy system.

We can also update the entire system with a simple command and a reboot:
$ sudo snappy versions
$ sudo snappy update
$ sudo reboot

And we can rollback to the previous version!
$ sudo snappy rollback
$ sudo reboot

Here's a short screencast of all of the above...


While the downloadable image is available for your local testing today, you will very soon be able to launch Snappy Ubuntu instances in your favorite public (Azure, GCE, AWS) and private clouds (OpenStack).


Enjoy!

Ubuntu Core with Snappy was recently announced and a key ingredient for snappy is security. Snappy applications are confined by AppArmor and the confinement story for snappy is an evolution of the security model for Ubuntu Touch. The basic concepts for confined applications and the AppStore model pertain to snappy applications as well. In short, snappy applications are confined using AppArmor by default and this is achieved through an easy to understand, use and developer-friendly system. Read the snappy security specification for all the nitty gritty details.

A developer doc will be published soon.

The call for an Ubuntu Foundation has come up again. It has been discussed many times before, ever since an announcement was made many years ago which left a number of people confused about the state of things.

The way I understood the initial announcement was that a trust had been set up, so that if aliens ever kidnapped our fearless leader, or if he decided that beekeeping was more interesting than Ubuntu, we could still go on and bring the best flavour of linux to the world.

Ok, now back to the current discussion. An Ubuntu Foundation seems to have quite an appeal to some. The question to me is: which problems would it solve?

Looking at it from a very theoretical point of view, an Ubuntu foundation could be a place where you separate “commercial” from “public” interests, but how would this separation work? Who would work for which of the entities? Would people working for the Ubuntu foundation have to review Canonical’s paperwork before they can close deals? Would there be a board where decisions have to be pre-approved? Which separation would generally happen?

Right now, Ubuntu’s success is closely tied to Canonical’s success. I consider this a good thing. With every business win of Canonical, Ubuntu gets more exposure in the world. Canonical’s great work in the support team, in the OEM sector or when closing deals with governments benefits Ubuntu to a huge degree. It’s like two sides of a coin right now. Also: Canonical pays the bills for Ubuntu’s operations. Data centers, engineers, designers and others have to be paid.

In theory it all sounds fine: “you get to have a say”, “more transparency”, etc. I don’t think many realise though, that this will mean that additional people will have to sift through legal and other documents, that more people will be busy writing reports, summarising discussions, that there will be more need for admin , that customers will have to wait longer, that this will in general have to cost more time and money.

I believe that bringing in a new layer will bring incredible amounts of work and open up endless possibilities for politics and easily bring things to a stand-still.

Will this fix Ubuntu’s problems? I absolutely don’t think so. Could we be more open, more inspiring and more inviting? Sure, but demanding more transparency and more separation is not going to bring that.

The Ubuntu Core Apps project has proven that the Ubuntu community is not only capable of building fantastic software, but they’re capable of the meeting the same standards, deadlines and requirements that are expected from projects developed by employees. One of the things that I think made Core Apps so successful was the project management support that they all received from Alan Pope.

Project management is common, even expected, for software developed commercially, but it’s just as often missing from community projects. It’s time to change that. I’m kicking off a new personal[1] project, I’m calling it the Ubuntu Incubator.

get_excited_banner_banner_smallThe purpose of the Incubator is to help community projects bootstrap themselves, obtain the resources they need to run their project, and put together a solid plan that will set them on a successful, sustainable path.

To that end I’m going to devote one month to a single project at a time. I will meet with the project members regularly (weekly or every-other week), help define a scope for their project, create a spec, define work items and assign them to milestones. I will help them get resources from other parts of the community and Canonical when they need them, promote their work and assist in recruiting contributors. All of the important things that a project needs, other than direct contributions to the final product.

I’m intentionally keeping the scope of my involvement very focused and brief. I don’t want to take over anybody’s project or be a co-founder. I will take on only one project at a time, so that project gets all of my attention during their incubation period. The incubation period itself is very short, just one month, so that I will focus on getting them setup, not on running them.  Once I finish with one project, I will move on to the next[2].

How will I choose which project to incubate? Since it’s my time, it’ll be my choice, but the most important factor will be whether or not a project is ready to be incubated. “Ready” means they are more than just an idea: they are both possible to accomplish and feasible to accomplish with the person or people already involved, the implementation details have been mostly figured out, and they just need help getting the ball rolling. “Ready” also means it’s not an existing project looking for a boost, while we need to support those projects too, that’s not what the Incubator is for.

So, if you have a project that’s ready to go, but you need a little help taking that first step, you can let me know by adding your project’s information to this etherpad doc[3]. I’ll review each one and let you know if I think it’s ready, needs to be defined a little bit more, or not a good candidate. Then each month I’ll pick one and reach out to them to get started.

Now, this part is important: don’t wait for me! I want to speed up community innovation, not slow it down, so even if I add your project to the “Ready” queue, keep on doing what you would do otherwise, because I have no idea when (or if) I will be able to get to yours. Also, if there are any other community leaders with project management experience who have the time and desire to help incubate one of these project, go ahead and claim it and reach out to that team.

[1] While this compliments my regular job, it’s not something I’ve been asked to do by Canonical, and to be honest I have enough Canonical-defined tasks to consume my working hours. This is me with just my community hat on, and I’m inclined to keep it that way.

[2] I’m not going to forget about projects after their month is up, but you get 100% of the time I spend on incubation during your month, after that my time will be devoted to somebody else.

[3] I’m using Etherpad to keep the process as lightweight as possible, if we need something better in the future we’ll adopt it then.

Try These 7 Tips in Your Next Blog Post


In a presentation to my colleagues last week, I shared a few tips I've learned over the past 8 years, maintaining a reasonably active and read blog.  I'm delighted to share these with you now!

1. Keep it short and sweet


Too often, we spend hours or days working on a blog post, trying to create an epic tome.  I have dozens of draft posts I'll never finish, as they're just too ambitious, and I should really break them down into shorter, more manageable articles.

Above, you can see Abraham Lincoln's Gettysburg Address, from November 19, 1863.  It's merely 3 paragraphs, 10 sentences, and less than 300 words.  And yet it's one of the most powerful messages ever delivered in American history.  Lincoln wrote it himself on the train to Gettysburg, and delivered it as a speech in less than 2 minutes.

2. Use memorable imagery


Particularly, you need one striking image at the top of your post.  This is what most automatic syndicates or social media platforms will pick up and share, and will make the first impression on phones and tablets.

3. Pen a catchy, pithy title


More people will see or read your title than the post itself.  It's sort of like the chorus to that song you know, but you don't know the rest of the lyrics.  A good title attracts readers and invites re-shares.

4. Publish midweek


This is probably more applicable for professional, rather than hobbyist, topics, but the data I have on my blog (1.7 million unique page views over 8 years), is that the majority of traffic lands on Tuesday, Wednesday, and Thursday.  While I'm writing this very post on a rainy Saturday morning over a cup of coffee, I've scheduled it to publish at 8:17am (US Central time) on the following Tuesday morning.

5. Share to your social media circles


My posts are generally professional in nature, so I tend to share them on G+, Twitter, and LinkedIn.  Facebook is really more of a family-only thing for me, but you might choose to share your posts there too.  With the lamentable death of the Google Reader a few years ago, it's more important than ever to share links to posts on your social media platforms.

6. Hope for syndication, but never expect it

So this is the one "tip" that's really out of your control.  If you ever wake up one morning to an overflowing inbox, congratulations -- your post just went "viral".  Unfortunately, this either "happens", or it "doesn't".  In fact, it almost always "doesn't" for most of us.

7. Engage with comments only when it makes sense


If you choose to use a blog platform that allows comments (and I do recommend you do), then be a little careful about when and how to engage in the comments.  You can easily find yourself overwhelmed with vitriol and controversy.  You might get a pat on the back or two.  More likely, though, you'll end up under a bridge getting pounded by a troll.  Rather than waste your time fighting a silly battle with someone who'll never admit defeat, start writing your next post.  I ignore trolls entirely.

A Case Study

As a case study, I'll take as an example the most successful post I've written: Fingerprints are Usernames, Not Passwords, with nearly a million unique page views.

  1. The entire post is short and sweet, weighing in at under 500 words and about 20 sentences
  2. One iconic, remarkable image at the top
  3. A succinct, expressive title
  4. Published on Tuesday, October 1, 2013
  5. 1561 +1's on G+, 168 retweets on Twitter
  6. Shared on Reddit and HackerNews (twice)
  7. 434 comments, some not so nice
Cheers!

I had the great pleasure to deliver a 90 minute talk at the USENIX LISA14 conference, in Seattle, Washington.

During the course of the talk, we managed to:

  • Deploy OpenStack Juno across 6 physical nodes, on an Orange Box on stage
  • Explain all of the major components of OpenStack (Nova, Neutron, Swift, Cinder, Horizon, Keystone, Glance, Ceilometer, Heat, Trove, Sahara)
  • Explore the deployed OpenStack cloud's Horizon interface in depth
  • Configured Neutron networking with internal and external networks, as well as a gateway and a router
  • Setup our security groups to open ICMP and SSH ports
  • Upload an SSH keypair
  • Modify the flavor parameters
  • Update a bunch of quotas
  • Add multiple images to Glance
  • Launch some instances until we max out our hypervisor limits
  • Scale up the Nova Compute nodes from 3 units to 6 units
  • Deploy a real workload (Hadoop + Hive + Kibana + Elastic Search)
  • Then, we deleted the entire environment, and ran it all over again from scratch, non-stop
Slides and a full video are below.  Enjoy!

When things are moving fast and there’s still a lot of work to do, it’s sometimes easy to forget to stop and take the time to say “thank you” to the people that are helping you and the rest of the community. So every November 20th we in Ubuntu have a Community Appreciation Day, to remind us all of the importance of those two little words. We should of course all be saying it every day, but having a reminder like this helps when things get busy.

Like so many who have already posted their appreciation have said, it would be impossible for me to thank everybody I want to thank. Even if I spent all day on this post, I wouldn’t be able to mention even half of them.  So instead I’m going to highlight two people specifically.

First I want to thank Scarlett Clark from the Kubuntu community. In the lead up to this last Ubuntu Online Summit we didn’t have enough track leads on the Users track, which is one that I really wanted to see more active this time around. The track leads from the previous UOS couldn’t do it because of personal or work schedules, and as time was getting scarce I was really in a bind to find someone. I put out a general call for help in one of the Kubuntu IRC channels, and Scarlett was quick to volunteer. I really appreciated her enthusiasm then, and even more the work that she put in as a first-time track lead to help make the Users track a success. So thank you Scarlett.

Next, I really really want to say thank you to Svetlana Belkin, who seems to be contributing in almost every part of Ubuntu these days (including ones I barely know about, like Ubuntu Scientists). She was also a repeat track lead last UOS for the Community track, and has been contributing a lot of great feedback and ideas on ways to make our amazing community even better. Most importantly, in my opinion, is that she’s trying to re-start the Ubuntu Leadership team, which I think is needed now more than ever, and which I really want to become more active in once I get through with some deadline-bound work. I would encourage anybody else who is a leader in the community, or who wants to be one, to join her in that. And thank you, Svetlana, for everything that you do.

It is both a joy and a privilege to be able to work with people like Scarlett and Svetlana, and everybody else in the Ubuntu community. Today more than ever I am reminded about how lucky I am to be a part of it.

Last week was our second ever Ubuntu Online Summit, and it couldn’t have gone better. Not only was it a great chance for us in Canonical to talk about what we’re working on and get community members involved in the ongoing work, it was also an opportunity for the community to show us what they have been working on and give us an opportunity to get involved with them.

Community Track leads

This was also the second time we’ve recruited track leads from among the community. Traditionally leading a track was a responsibility given to one of the engineering managers within Canonical, and it was up to them to decide what sessions to put on the UDS schedule. We kept the same basic approach when we went to online vUDS. But starting with UOS 14.06, we asked leaders in the community to help us with that, and they’ve done a phenomenal job. This time we had Nekhelesh RamananthanJosé Antonio ReySvetlana BelkinRohan GargElfy, and Scarlett Clark take up that call, and they were instrumental in getting even more of the community involved

Community Session Hosts

uos_creatorsMore than a third of those who created sessions for this UOS were from the community, not Canonical. For comparison, in the last in-person UDS, less than a quarter of session creators were non-Canonical. The shift online has been disruptive, and we’ve tried many variations to try and find what works, but this metric shows that those efforts are starting to pay off. Community involvement, indeed community direction, is higher in these Online Summits than it was in UDS. This is becoming a true community event: community focused, community organized, and community run.

Community Initiatives

The Ubuntu Online Summit wasn’t just about the projects driven by Canonical, such as the Ubuntu desktop and phone, there were many sessions about projects started and driven by members of the community. Last week we were shown the latest development on Ubuntu MATE and KDE Plasma 5 from non-Canonical lead flavors. We saw a whole set of planning sessions for community developed Core Apps and an exciting new Component Store for app developers to share bits of code with each other. For outreach there were sessions for providing localized ISOs for loco teams and expanding the scope of the community-lead Start Ubuntu project. Finally we had someone from the community kick off a serious discussion about getting Ubuntu running on cars. Cars! All of these exciting sessions were thought up by, proposed by, and run by members of the community.

Community Improvements

This was a great Ubuntu Online Summit, and I was certainly happy with the increased level of community involvement in it, but we still have room to make it better. And we are going to make it better with help from the community. We will be sending out a survey to everyone who registered as attending for this UOS to gather feedback and ideas, please take the time to fill it out when you get the link. If you attended but didn’t register there’s still time, go to the link above, log in and save your attendance record. Finally, it’s never too early to start thinking about the next UOS and what sessions you might want to lead for it, so that you’re prepared when those track leads come knocking at your door.

A couple of people have reached out to me via LinkedIn and reminded me that my three year work anniversary happened last Friday. Three years since I left my job at a local place to go work for the Canonical where I got the chance to be paid to work on open source software and better my Python skills with the team working on Launchpad. My wife wasn’t quite sure. “You’ve only been at your job a year and a half, and your last one was only two years. What makes this different?”

What’s amazing, looking back, is just how *right* the decision turned out to be. I was nervous at the time. I really wasn’t Launchpad’s biggest fan. However, the team I interviewed with held this promise of making me a better developer. They were doing code reviews of every branch that went up to land. They had automated testing, and they firmly believed in unit and functional tests of the code. It was a case of the product didn’t excite me, but the environment, working with smart developers from across the globe, was exactly what I felt like I needed to move forward with my career, my craft.

I joined my team on Launchpad in a squad of four other developers. It was funny. When I joined I felt so lost. Launchpad is an amazing and huge bit of software, and I knew I was in over my head. I talked with my manager at the time, Deryck, and he told me “Don’t worry, it’ll take you about a year to get really productive working on Launchpad.” A year! Surely you jest, and if you’re not jesting…wtf did I just get myself into?

It was a long road and over time I learned how to take a code review (a really hard skill for many of us), how to do one, and how to talk with other smart and opinionated developers. I learned the value of the daily standup, how to manage work across a kanban board. I learned to really learn from others. Up until this point I’d always been the big fish in a small pond and suddenly I was the minnow hiding in the shallows. Forget books on how to code, just look at the diff in the code review you’re reading right now. Learn!

My boss was right, it was nearly ten months before I really felt like I could be asked to do most things in Launchpad and get them done in an efficient way. Soon our team was moved on from Launchpad to other projects. It was actually pretty great. On the one hand, “Hey! I just got the hang of this thing” but, on the other hand, we were moving on to new things. Development life here has never been one of sitting still. We sit down and work on the Ubuntu cycle of six month plans, and it’s funny because even that is such a long time. Do you really know what you’ll be doing six months from now?

Since that time in Launchpad I’ve gotten work on several different projects and I ended up switching teams to work on the Juju Gui. I didn’t really know a lot about this Juju thing, but the Gui was a fascinating project. It’s a really large scale JavaScript application. This is no “toss some jQuery on a web page” thing here.

I also moved to work under a new manager Gary. As my second manager since starting at Canonical and I was amazed at my luck. Here I’ve had two great mentors that made huge strides in teaching me how to work with other developers, how to do the fun stuff, the mundane, and how to take pride in the accomplishments of the team. I sit down at my computer every day and I’ve got the brain power of amazing people at my disposal over irc, Google Hangouts, email, and more. It’s amazing to think that at these sprints we do, I’m pretty much never the smartest person in the room. However, that’s what’s so great. It’s never boring and when there’s a problem the key is that we put our joint brilliant minds to the problem. In every hard problem we’ve faced I’ve never found that a single person had the one true solution. What we come up with together is always better than what any of us had apart.

When Gary left and there was a void for team lead and it was something I was interested in. I really can’t say enough awesome things about the team of folks I work with. I wanted to keep us all together and I felt like it would be great for us to try to keep things going. It was kind of a “well I’ll just try not to $#@$@# it up” situation. That was more than nine months ago now. Gary and Deryck taught me so much, and I still have to bite my tongue and ask myself “What would Gary do” at times. I’ve kept some things the same, but I’ve also brought my own flavor into the team a bit, at least I like to think so. These days my Github profile doesn’t show me landing a branch a day, but I take great pride in the progress of the team as a whole each and every week.

The team I run now is as awesome a group of people, the best I could hope to work for. I do mean that, I work for my team. It’s never the other way around and that’s one lesson I definitely picked up from my previous leads. The projects we’re working on are exciting and new and are really important to Canonical. I get to sit in and have discussions and planning meetings with Canonical super genius veterans like Kapil, Gustavo, and occasionally Mark Shuttleworth himself.

Looking back I’ve spent the last three years becoming a better developer, getting an on the job training course on leading a team of brilliant people, and crash course on thinking about the project, not just as the bugs or features for the week, but for the project as it needs to exist in three to six months. I’ve spent three years bouncing between “what have I gotten myself into, this is beyond my abilities” to “I’ve got this. You can’t find someone else to do this better”. I always tell people that if you’re not swimming as hard as you can to keep up, find another job. I feel like three years ago I did that and I’ve been swimming ever since.

Three years is a long time in a career these days. It’s been a wild ride and I can’t thank the folks that let me in the door, taught me, and have given me the power to do great things with my work enough. I’ve worked by butt off in Budapest, Copenhagen, Cape Town, Brussels, North Carolina, London, Vegas, and the bay area a few times. Will I be here three years from now? Who knows, but I know I’ve got an awesome team to work with on Monday and we’ll be building an awesome product to keep building. I’m going to really enjoy doing work that’s challenging and fulfilling every step of the way.
