Docker 1.0.1 is available for testing, in Ubuntu 14.04 LTS!Docker 1.0.1 has landed in the trusty-proposed archive, which we hope to SRU to trusty-updates very soon.  We would love to have your testing feedback, to ensure both upgrades from Docker ... [More] 0.9.1, as well as new installs of Docker 1.0.1 behave well, and are of the highest quality you have come to expect from Ubuntu's LTS  (Long Term Stable) releases!  Please file any bugs or issues here.

Moreover, this new version of the Docker package now installs the Docker binary to /usr/bin/docker, rather than /usr/bin/ in previous versions. This should help Ubuntu's Docker package more closely match the wealth of documentation and examples available from our friends upstream.

A big thanks to Paul Tagliamonte, James Page, Nick Stinemates, Tianon Gravi, and Ryan Harper for their help upstream in Debian and in Ubuntu to get this package updated in Trusty!  Also, it's probably worth mentioning that we're targeting Docker 1.1.2 (or perhaps 1.2.0) for Ubuntu 14.10 (Utopic), which will release on October 23, 2014.

Here are a few commands that might help your testing...
Check What Candidate Versions are Available$ sudo apt-get update
$ apt-cache show | grep ^Version:

If that shows 0.9.1~dfsg1-2 (as it should), then you need to enable the trusty-proposed pocket.
$ echo "deb trusty-proposed universe" | sudo tee -a /etc/apt/sources.list
$ sudo apt-get update
$ apt-cache show | grep ^Version:

And now you should see the new version, 1.0.1~dfsg1-0ubuntu1~ubuntu0.14.04.1, available (probably in addition to 1.0.1~dfsg1-0ubuntu1~ubuntu0.14.04.1).UpgradesCheck if you already have Docker installed, using:

$ dpkg -l

If so, you can simply upgrade.

$ sudo apt-get upgrade

And now, you can check your Docker version:

$ sudo dpkg -l | grep -m1 ^ii | awk '{print $3}'0.9.1~dfsg1-2

New InstallationsYou can simply install the new package with:
$ sudo apt-get install

And ensure that you're on the latest version with:
$ dpkg -l | grep -m1 ^ii | awk '{print $3}'
Running DockerIf you're already a Docker user, you probably don't need these instructions.  But in case you're reading this, and trying Docker for the first time, here's the briefest of quick start guides :-)
$ sudo docker pull ubuntu
$ sudo docker run -i -t ubuntu /bin/bash

And now you're running a bash shell inside of an Ubuntu Docker container.  And only bash!
root@1728ffd1d47b:/# ps -ef
root 1 0 0 13:42 ? 00:00:00 /bin/bash
root 8 1 0 13:43 ? 00:00:00 ps -ef

If you want to do something more interesting in Docker, well, that's whole other post ;-)

Today I was experimenting with coding live, on air with google hangouts. It is an interesting idea IMHO as it adds visibility to a process that is done in the open but rarely transparently in a way others can watch and learn from.

I've ... [More] recorded two videos today:  Live coding: adding a man page for the new category unit and Live coding: fixing bug If you want to see how I work (including and all the mistakes I make :-) do watch them and give me feedback so that I can get learn and get better at it. [Less]

A few years ago, I learned from Myriam's fine blog how to build Amarok from source, which is kept in git. It sounds mysterious, but once all the dependencies are installed, PATH is defined and the environment is properly set up, it is extremely easy ... [More] to refresh the source (git pull) and rebuild. In fact, I usually use the up-arrow in the konsole, which finds the previous commands, so I rarely have to even type anything! Just hit return when the proper command is in place.

Now we're using git for the KDE Frameworks book, so I learned how to not only pull the new or changed source files, but also to commit my own few or edited files locally, then push those commits to git, so others can see and use them.

To be able to write to the repository, an SSH key must be uploaded, in this case done in the KDE Identity account. If the Identity account is not a developer account, that must first be granted.

Just as in building Amarok, first the folders need to be created, and the repository cloned. Once cloned, I can see either in konsole or Dolphin the various files. It's interesting to me to poke around in most of them, but the ones I work in are markdown files, which is a type of text file. I can open them in kate (or your editor of choice) either from Dolphin or directly from the cli (for instance kate ki18n/

Once edited, save the file, then it's time to commit. If there are a number of files to work on, they can be all committed at once. git commit -a is the command you need. Once you hit return, you will be immediately put into nano, a minimal text editor. Up at the top, you will see it is waiting for your commit message, which is a short description of the file or the changes you have made. Most of my commits have said something like "Edited for spelling and grammar." Once your message is complete, hit Control X, and y and return to save your changes.

It's a good idea to do another git pull just to be sure no one else has pushed a conflicting file while the commit message was being crafted, then git push. At this point the passphrase for the ssh key is asked for; once that is typed and you hit return, you'll get something like the following:

Counting objects: 7, done.                                                                                                                                                                              
Delta compression using up to 8 threads.

In this case, the new file is now part of the KDE Frameworks 5 book repository. Git is a really nifty way to keep files of any sort organized and backed up. I'm really happy that we decided to develop the book using this powerful tool. [Less]

It’s been about a year since I started building my own Steam console for my living room. A ton has changed since then. SteamOS has been released, In Home Streaming is out of beta and generally speaking the living room experience has gotten a ton ... [More] better.

This blog post will be a summary of what’s changed in the past year, in the hopes that it will help someone who might be interested in building their own “next-gen console” for about the same price, and take advantage of nicer hardware and all the things that PC gaming has to offer.

My first blog post on building your own box.
A talk I gave at Penguicon on SteamOS for background.

Step 1: Choosing the hardware

I consider the NVIDIA GTX 750Ti to be the best thing to happen in hardware for this sort of project. It’s based on their newest Maxwell technology so it runs cool, it does not need a special power supply plug, and it’s pretty small. It’s also between $120-$150 – which means nearly any computer is now capable of becoming a game console. And a competent one at that.

I have settled on the Cooler Master 110 case, which is one of the least obnoxious PC case you can find that won’t look too bad in the living room. Unfortunately Valve’s slick-looking case did not kick the case makers into making awesome-looking living room style cases. The closest you can find is the Silverstone RVZ01, which has the right insides, but they ruined the outside with crazy plastic ribs. The Digital Storm Bolt II looks great, but you can’t buy the case seperately. Both cases have CD drives for some reason, boo!

Nvidia has a great guide on building a PC within the console-price range if you want to look around. I also recommend checking out r/buildapc, which has tons of Mini-ITX/750Ti builds.

Another alternative is the excellent Intel NUC and Gigabyte Brix. These make for great portable machines, but for the upcoming AAA titles for Linux like Metro Redux, Star Citizen, and so on I decided to go with a dedicated graphics card. Gigabyte makes a very interesting model that is the size of a NUC, but with a GTX 760(!). This looks to be ideal, but unfortunately when Linus reviewed it he found heat/throttling issues. When they make a Maxwell based one of these it will likely be awesome.

Don’t forget the controller. The Xbox wireless ones will work out of the box. I recommend avoiding the off-brand dongles you see on Amazon, they can be hit or miss.

Step 2: Choosing the software

I’ve been using SteamOS since it came out. The genious about SteamOS is that fundamentally it does only 2 things. It boots, and then runs Steam Big Picture (BPM) mode. This means for a dedicated console, the OS is really not important. I have 2 drives in the box, one with SteamOS, and one with Ubuntu running BPM. After running both I prefer Ubuntu/Steam to SteamOS:

Faster boot (Upstart v. SysV)
PPAs enable fresh access to new Nvidia drivers and Plex Home Theater
Newer kernels and access to HWE kernels over the next 5 years

I tend to alternate between the two, but since I am more familiar with Ubuntu it makes it easier to use for, so the rest of this post will cover how to build a dedicated Steam Box using Ubuntu.

This isn’t to say SteamOS is bad, in fact, setting it up is actually easier than doing the next few steps; remember that the entire point is to not care about the OS underneath, and get you into Steam. So build whatever is most comfortable for you!

Step 3: Installation

These are the steps I am currently doing. It’s not for beginners, you should be comfortable admining an Ubuntu system.

Install Ubuntu 14.04.
(Optional) - Install openssh-server. I don’t know about you but lugging a keyboard/mouse back and forth to my living room is not my idea of a good time. I prefer to sit on the couch, and ssh into the box from my laptop.
Add the xorg-edgers PPA. You don’t need this per se, but let’s go all in!
Install the latest Nvidia drivers: As of this writing, nvidia-graphics-drivers-343.

After you’ve installed the drivers and all the security updates you should reboot to get to your nice new clean desktop system. Now it’s time to make it a console:

Log in, and install Steam. Log into steam, make sure it works.
Add the Marc Deslaurier’s SteamOS packages PPA. These are rebuilt for Ubuntu and he does a great job keeping them up to date.
sudo apt-get install steamos-compositor steamos-modeswitch-inhibitor steamos-xpad-dkms
Log out, and in the login screen, click on the Ubuntu symbol by the username and select the Steam session. This will get you the dedicated Steam session. Make sure that works. Exit out of that and now let’s make it so we can boot into that new session by default
Enable autologin in LightDM after the fact so that when your machine boots it goes right into Steam’s Big Picture mode.

We’re using Valve’s xpad module instead of xboxdrv because that’s what they use in SteamOS and I don’t want to deviate too much. But if you prefer about xboxdrv then follow this guide.

Steam updates itself at the client level so there’s no need to worry about that, the final step for a console-like experience is to enable automatic updates. Remember you’re using PPAs, so if you’re not confident that you can fix things, just leave it and do maintenance by hand every once in a while.

Step 4: Home Theater Bling

If you’re going to have a nice living room box, then let’s use it for other things. I have a dedicated server with media that I share out with Plex Media Server, so in this step I’ll install the client side.

Plex Home Theater:

sudo add-apt-repository ppa:plexapp/plexht
sudo add-apt-repository ppa:ppa:pulse-eight/libcec
sudo apt-get update && sudo apt-get install plexhometheater

In Steam you can then click on the + symbol, Add a non-steam game, and then add Plex. Use the gamepad (not the stick) to navigate the UI once you launch it. If you prefer XBMC/Kodi you can install that instead. I found that the controller also works out of the box there, so it’s a nice experience no matter which one you choose.

Step 5: In Home Streaming

This is a killer Steam feature, that allows you to stream your Windows games to your new console. It’s very straight forward, just have both machines on and logged into Steam on the same network, they will autodiscover each other, and your Windows games will show up in your Ubuntu/Steam UI, and you can stream them. Though it works suprisingly well over wireless, you’ll definately want to ensure you’ve got gigabit ethernet if you want to stream games 1080p at 60 frames per second.


And that’s basically it! There’s tons of stuff I’ve glossed over, but these are the basic steps. There’s lots of little things you can do, like remove a bunch of desktop packages you won’t need (so you don’t need to download and update them) and other tips and tricks, I’ll try to keep everyone up to date on how it’s going.

Enjoy your new next-gen gaming console!


You can change out the plymouth theme to use the one for SteamOS - but I have an SSD in the box and combined with the fast boot it never comes up for me anyway.
It’d be cool to make a prototype of Ubuntu Core and then provide Steam in an LXC container on top of that so we don’t have to use a full blown desktop ISO. [Less]

Recognition is like money, it only really has value when it’s being passed between one person and another. Otherwise it’s just potential value, sitting idle.  Communication gives life to recognition, turning it’s potential value into real ... [More] value.

As I covered in my previous post, Who do you contribute to?, recognition doesn’t have a constant value.  In that article I illustrated how the value of recognition differs depending on who it’s coming from, but that’s not the whole story.  The value of recognition also differs depending on the medium of communication.

Over at the Community Leadership Knowledge Base I started documenting different forms of communication that a community might choose, and how each medium has a balance of three basic properties: Speed, Thoughtfulness and Discoverability. Let’s call this the communication triangle. Each of these also plays a part in the value of recognition.

Again, much like money, recognition is something that is circulated.  It’s usefulness is not simply created by the sender and consumed by the receiver, but rather passed from one person to another, and then another.  The faster you can communicate recognition around your community, the more utility you can get out of even a small amount of it. Fast communications, like IRC, phone calls or in-person meetups let you give and receive a higher volume of recognition than slower forms, like email or blog posts. But speed is only one part, and faster isn’t necessarily better.

Where speed emphasizes quantity, thoughtfulness is a measure of the quality of communication, and that directly affects the value of recognition given. Thoughtful communications require consideration upon both receiving and replying. Messages are typically longer, more detailed, and better presented than those that emphasize speed. As a result, they are also usually a good bit slower too, both in the time it takes for a reply to be made, and also the speed at which a full conversation happens. An IRC meeting can be done in an hour, where an email exchange can last for weeks, even if both end up with the same word-count at the end.

The third point on our communication triangle, discoverability, is a measure of how likely it is that somebody not immediately involved in a conversation can find out about it. Because recognition is a social good, most of it’s value comes from other people knowing who has given it to whom. Discoverability acts as a multiplier (or divisor, if done poorly) to the original value of recognition.

There are two factors to the discoverability of communication. The first, accessibility, is about how hard it is to find the conversation. Blog posts, or social media posts, are usually very easy to discover, while IRC chats and email exchanges are not. The second factor, longevity, is about how far into the future that conversation can still be discovered. A social media post disappears (or at least becomes far less accessible) after a while, but an IRC log or mailing list archive can stick around for years. Unlike the three properties of communication, however, these factors to discoverability do not require a trade off, you can have something that is both very accessible and has high longevity.

Finding Balance
Most communities will have more than one method of communication, and a healthy one will have a combination of them that compliment each other. This is important because sometimes one will offer a more productive use of your recognition than another. Some contributors will respond better to lots of immediate recognition, rather than a single eloquent one. Others will respond better to formal recognition than informal.  In both cases, be mindful of the multiplier effect that discoverability gives you, and take full advantage of opportunities where that plays a larger than usual role, such as during an official meeting or when writing an article that will have higher than normal readership.
