Successful Hack-In, 01 Mar 2012!

DreamHost has a new core set of cloud developers now based in Atlanta, and a new Meetup group to go with that :-) Today there was a global OpenStack Hack-In, and I just posted a summary to our Meetup discussion page, but since I desperately need to do some blogging, I'm republishing here :-) (with some minor tweaks...)

We had fun in person, there was good chatter on IRC with the Colorado and San Francisco teams, and we had a great time digging into OpenStack some more.

Technical highlights include:
  • testing out development deployments of OpenStack using Vagrant (some successes, some blockers)
  • testing out dev deployments of OpenStack using VirtualBox directly
  • filed some bugs for issues in horizon regarding error feedback to users and how the documentation is generated
  • dug into issues with logging and inconsistencies in datestamps
  • uncovered some weirdness with the usage of gnu screen and hanging services/partial devstack installs due to sudo assumptions (devstack assumes a passwordless sudo, and will label an install as failed if it gets hung up on the apache log tail, waiting for a password, even if the install was successful and all the services started correctly)
  • Doug Hellmann made his first commit upstream to OpenStack
On the non-technical, fun side:
  • Thanks for Zenoss for the fun swag today smile (the Zebras are still staring at me... I think they're going to be making an appearance in ToyStory 5)
  • Even more thanks to Zenoss for the offer to become an OpenStack Atlanta Sponsor (food, drinks, and swag)!
  • Thanks to DreamHost for the AMAZING coffee and danishes from The Village Corner Restaurant/Basket Bakery. Seriously. That was the best coffee I have ever had. In. My. Life.
  • Also, thanks DreamHost for the pizza and the sweet potato pies!


We took a couple snapshots of the event, and I'll be posting those soon on the Meetup page, but for the super-impatient, they're up on Flickr right now smile

Uncle Canonical Wants U!

you and uTouch, that is. And more!

Do you love Ubuntu? Are you an HCI freak? Are you an X hacker, kernel driver maintainer, Linux input enthusiast, Qt or GTK application developer, C/C++ hacker?

Do you enjoy being part of online technical communities? Are you actively involved in open source projects? Do you enjoy advocating for software?

Do you love test-driven development and thirst for high-quality open source software running on devices with touch interfaces?

Does the idea of working from home in your own time-zone, on cutting-edge, strategic projects at Canonical have you sitting on the edge of your seat?

If so, then please send me your resumé/CV! I'm looking for a few brilliant engineers as we grow our Product Strategy teams (DX, Design, and others).

Canonical and Codethink at Bostom GNOME Summit

Today is the second day of the Boston GNOME Summit, and the second day of Canonical providing morning sustenance for the hackers here. Codethink and Canonical coordinated these efforts, with Codethink sponsoring food later today. It warms my heart that we can do this sort of thing.

Yesterday Cody Russell and I held a session about getting a gesture API into GTK 3.x. There were a great many questions about the uTouch framework, how we're handling multi-touch in the absence of MT support in X (coming in XInput 2.1), and what sort of dependencies would be needed (none! if GEIS is present on the system, gesture support will be added at build-time). At the end of the session, there was a consensus for Cody to present his plans to the GTK developers list and then to start getting branches reviewed for merge. We're hoping to make it for GTK 3.2.

In this vein, Cody and I have been hacking on libgrope for GTK compatibility, and this is serving as the sandbox for the GTK 3 gesture API development. My efforts have been focused on creating the GTK 2 Python C extension for grope. Given that the last time I coded C was in 1989 (and then a bit later in the mid-90s, when I had to hack a slackware driver to get ethernet working), this has been quite an effort. However, after a night and morning of hacking, I've got a handle on C extensions and am using the example code I wrote as the basis for pygrope. I've even managed to rope Barry Warsaw into reviewing the C extension code for us, to be sure we're not doing anything too crazy :-)

The Python C extension will be of immediate use to us in our test harness for gestures and exercising the stack. We will be creating a GTK app for recording user gestures for later playback and inclusion in test suites.

HCI at Canonical


uTouch

Back in March, I blogged about future possibilities (in a blue-sky sense) of multi-touch, mentioning the project management I was doing for MT hardware kernel driver support in Lucid (and then proceeding to dive into the deep end of speculation). It's now an Ubuntu cycle later, and holy crap... I'm having a hard time finding the words. I think the blog title says it all. But I'll try to elaborate :-)

Unless you've been living under a rock, you've probably noticed the big announcements we made a few weeks ago:
For the next few days, we were all over Google news. This was quite a shock, given that we'd been heads-down into the project for so long and hadn't really come up for air nor fully anticipated the impact (to others or ourselves). Needless to say, after the intense amount of work that the team had engaged in over the previous couple months, this was quite gratifying, if somewhat unexpected.

There has been a lot of discussion in blog posts, mail lists, IRC (#ubuntu-touch on freenode.net), Launchpad bugs and merge proposals, etc., so much so that touchscreens now pursue me feverishly when I sleep at night. I'm really not interested in writing more of the same :-)

As such, I want to mix things up a bit...

HCI Remixed

I've been reading an amazing anthology of essays on human-computer interaction. I still haven't finished the book (yeah, I've got about 10 in-progress titles on my nightstand), but am relishing every word in this particular collection. The book is HCI Remixed: Reflections on Works That Have Influenced the HCI Community.

While doing some research at the beginning of the Maverick development cycle, I came across HCI Remixed at the local library -- the title intrigued me and I couldn't resist. Weeks later, after having maxed out the number of times I could renew the book, I just purchased it -- I simply couldn't get enough of the book. Every essay I'd read up to that point was fantastic; each one provided volumes of information, experiences, insights, ideas for follow-up, etc. Whenever I finished one essay, I spent days and sometimes weeks reading up on references, pondering the past and future of human-computer interaction.

Due to the unusual nature of the book, describing it is surprisingly difficult. That being said, the MIT Press page gives you a great taste:
Over almost three decades, the field of human-computer interaction (HCI) has produced a rich and varied literature. Although the focus of attention today is naturally on new work, older contributions that played a role in shaping the trajectory and character of the field have much to tell us. The contributors to HCI Remixed were asked to reflect on a single work at least ten years old that influenced their approach to HCI. The result is this collection of fifty-one short, engaging, and idiosyncratic essays, reflections on a range of works in a variety of forms that chart the emergence of a new field.
If you're into HCI, learning from others, and discovering new sources of inspiration for your own work, this is simply a must-have book :-)

A Small Piece of History

By the time I checked the book out of the Golden public library, it was May and we had begun building the MT team. By July -- once it became clear how astounding the team's work was -- I realized that in 10 or 20 years I could very well be writing an article about Henrik, Chase, Stephen, Ikbel, and Rafi. Much like those in the book, I could be sharing the conversations I'd had with Stéphane Chatty, Mark Shuttleworth, Neil Patel, David Siegel, and John Lea. And that's only the crew which which I was collaborating or discussing directly. There are a lot of folks who've been working very hard on multi-touch infrastructure solutions and exploring ways of integrating these for several years (e.g., Peter Hutterer and Carlos Garnacho).

Though many foundations have been laid, as of yet (to the best of my knowledge), no Linux distribution has released a multi-touch stack that integrated gestures in a unified manner across everything from applications to window managers and beyond. This was something that Mark wanted us to provide to the open source world. In this spirit, the multitouch team hasn't just hacked things together to get a product out in time. A lot of generative, creative thought and care has gone into uTouch. A lot of original problem solving has taken place. Physics PhDs, kernel hackers, X.org hackers, driver creators, application integrators, toolkit gurus -- all of this knowledge was concentrated, applied, and used to distill a first approximation of what a gesture stack in Linux could look like, using the latest available technology and methodologies.

To be honest, we weren't really sure we could pull it off. There was a very good chance we could have failed at our task, quietly chalking up the loss as a lesson learned. Now that we've managed to shape these ideas into actual software, taken the threads of dreams and woven something real, we are thrilled to be engaging with others to see where all of us can take multi-touch and gestures from here.

Thanks to expert input from the wider open source community, we're already looking at ways in which we can improve upon the first version, ways of bringing new ideas and experiences to developers and users of multi-touch hardware running Linux. Things are only just warming up, and the greatest contributions have yet to be made. Every single person in the community has before them a world of possibilities for getting involved and creating the future human-computer interfaces for the free and open source world in the coming weeks and months. These are indeed exciting times.

Some Thoughts on the Mobile Device Interface

Smartphones: Yesterday's News


As some of you know, I started 2010 by working in a new position at Canonical: Ubuntu Project Manager. I've been having an absolute blast; working my butt off has never been more fun, challenging, or interesting. I'm finding that nearly every side-interest I've had in the past several years is coming to the forefront in my project management work.

There were all sorts of adjustments I needed to make before PM'ing again, and one of those was catching up on communication technology. I now live by email, calendars, IRC, Skype, and phone conversations. Gone are the days of going heads-down into some code for a week or two. I need to stay connected, 100% of the time. I needed to get a smartphone.

What I really wanted was a Nokia N900. Sadly, T-Mobile's not offering one, so I got an Android phone with a physical keyboard instead: a new G1. Yeah, out of date, but considering that I was still using a Razr, the G1 is cutting-edge ;-)

I gotta tell you, this little phone has changed my life. The craziest thing is not the apps, the Market, the features, etc.; it's the touchscreen that has made me a believer.

You Can Touch This


I can't believe how radically the touchscreen phone has changed my computing habits and preferences. When I sit down at my laptop or desktop to do something quickly, I don't want use the keyboard or mouse. I want to point, swipe, and tweak with my fingers. When I'm on the phone, my brain has my speaking and text-processing faculties tied up. To easily multitask while talking, I need to be able to use a different part of my brain: that part involved in motor control.

I like using the touchscreen so much that I will often use my G1 for tasks that are better suited for my laptop, merely because of the joy I get from using the interface.

Touch, tap, drag, push, swipe. I love it. Can't get enough of it.

The best thing of all? This is really silly: I love the virtual desktops and being able to navigate between them with a swipe. Whose idea was this? That designer or engineer needs to be promoted! I have never experienced a more intuitive way of switching virtual desktops. I didn't even know how much this was important to me until I used the G1. I want this for my laptop!

Having such a positive bias towards tactile technology, you can imagine my joy when I saw this Ubuntu blueprint. And then when I was asked to work with Bryce and Andy on the PM portion of multi-touch support, I was quite delighted. This will give application developers and device engineers what they need in order to start creating new exciting stuff for the Ubuntu world. You will be able to have an iPad-like experience on your Linux devices (that have the proper hardware).

The thing is, as much fun as tactile interfaces are, I want way more now. I've been given a taste... now I want the banquet.

An Interface for the Future


So the iPad has been getting lots of press. It's bigger than a phone, I like that: I could replace my pen-and-paper medium-sized Moleskine with one. The thing I like the best though? Yeah, you guessed it: the interface. Curling pages and apps that have been re-worked specifically for the new format/size. I love it when a device lets me use it in a way that is natural and intuitive, and provides visual (or other sensory) feedback on my use.

Apple has made, in my opinion, a good and interesting product. But certainly not a revolutionary one. It's a natural progression from what folks are already doing with smartphones and netbooks.
So let's talk about revolutionary :-)

Imagine you've got a crazy new shirt, one whose fibers convert your movements to electrical current and can power your devices. Perhaps it comes with a "battery net" for literally flexible power storage. Now imagine that some clever sod has equipped your shirt with sockets for micro-SD cards (or something similar). If you've read my "After the Cloud" posts, then you probably know where I'm going with this :-)

Now add some embedded micro-controllers, and bluetooth, a smart phone with cloud-controller software, and you've got a personal S3 with potentially terabytes of light-weight, wearable storage. And your phone controls the nodes, redundancy, failover, etc. Maybe your phone runs Ubuntu and you're pushing backups of your personal cloud onto your U1 account.

But how do we interface with all this great storage? Here comes the banquet I mentioned :-)

I want to be able to reach "into" my phone, grab an icon (application, file, contact, whatever) and put it where I want. But I mean really put it: I can pick up some data off my desktop, and throw it over my shoulder or at my feet. With appropriate sensing equipemnt on the power shirt's sleeves, my arms and hands are now the perfect "mice."

In fact, there's no more virtual desktop (that's old skool). One of the new primary functions of your mobile device is to peer "into" the halo of data that surrounds you now. You can either spin your virtual storage space around you like an inverted, 3D lazy susan, our you can physically move your phone around, like a diving mask peering into the water.

Closing Thoughts


The more data I have, the more I feel that I live in it. The problem is that our current tech forces us into tiny sardine cans and we have to consume our data with the equivalent of a single chop-stick. If I'm going to live in my data, I want to have the best possible experience of immersion that I can. I want an interface that can handle my future.

I could go on and on... I love this sort of thing. The important thing to know now is that the community is working on the building blocks for our technological future. The first steps are being made in open source software that will allow us to take giant, insanely cool steps in the not-to-distant future.

7 Years of Blogasmic Action


Earlier today, I was looking through old blog posts, reminding myself of issues and topics that I want to continue reflecting on actively. When I got to the end of the posts, I looked at the earliest date and realized that my seven-year blogiversary was this past Wednesday. At my vocalized comment to this effect, Marjorie asked what got me started on blogging. Interestingly, it ties in with my professional life over the past twleve years...

As a physics undergrad and employee of the University of Maryland, I was hired away by a large internet startup for my systems and programming background. Already a fan of Office Space, I got to experience the reality of cubicle life as the not-so-funny, real complement of that classic movie. However, it wasn't my personal experience of cubihell that had the biggest impact upon my psyche; it was the corporate atrocities suffered by various customers and partners of dot-boom era, high-rolling companies.

Already a passionate open-source user and contributor, it become one of my personal goals to make sure a greater number of people (especially those making decisions in companies) were informed about the software freedoms that were within their reach. Within two years of this epiphany, I had my own company and was open-source consulting for everything from small businesses to large international corporations and the Federal government. Everything I did was open source; all of it saved my customers from spending millions of dollars unnecessarily and the enslavement of proprietary lock-in.

It was at this time that I started blogging. My primary interest was to be a voice in the wilderness of consultants, finding other like-minded programmers, project managers, sales engineers, etc., who believed in "open business", transparency, and accountability. As time progressed, my blogging habits adapted to fill other needs in various communities. However, all of my professional decisions have remained true to that initial desire to work on technology that was not only free, but actively prevented the bondage of its users.

For the past year and a half, I've been working at Canonical, the company that funds and actively supports Ubuntu and the Ubuntu Community. Every time I work with a different engineer or a new team, I am blown away by two things: the incredible talent embodied in each interaction, and the dedication that each person has to improving how free technology is delivered to the world.

My blog posts have definitely changed in character over the past seven years. But I'm delighted that, where I once felt alone with my ideals, I can count true giants in the field among my fellow community members, cooworkers, and mentors.

Canonical's Vision


Canonical's most recent AllHands meeting finished last night (this morning, really... I can't believe I got up at 7:30am), and I'm somewhat at a loss for words. In a good way.

But I'll try anyway :-)

As someone who was highly skeptical of the validity of Canonical's business model prior to working here, I can say that not only do I not doubt our ability to be a hugely successful company, but I am deeply committed to that success. Before AllHands, Canonical had earned my respect and loyalty through the consistent support and care of its employees. After AllHands, I have a much greater practical, hands-on understanding of Canonical's strategies and the various projects involved in creating a reality of success.

What's more, though, is the completeness of my belief in the people and the vision. This is thanks to the massive exposure we've had during AllHands to the collective vision; the team projects; all the individuals with amazing histories, skills, unbelievable talent and ability to deliver; and most of all, the dedication that each employee of Canonical has to truly making the world a better place for anyone who depends upon technology.

Ubuntu is free, and that's great. But Canonical needs to be a huge commercial success if its free OS distribution is going to have the power to transform the market and thus people's lives. This AllHands has given me a complete picture of how that will happen: we're all working on a different part of this puzzle, and we're all making it happen.

Success in the marketplace is crucial. Not because of greed or the lust for power, but because we live in a world where value is exchanged. As part of that ecosystem, we want to bring the greatest value to the people. This is not "selling out"; it's selling. This does not give away a user's freedom; it helps guarantee its continued safety in a competitive, capitalist society.

If we want anyone to embrace Ubuntu instead of a non-free OS -- without asking our users to sacrifice anything -- we're going to need to make very serious changes in design, usability, integration, and stability. To do this in a clean, unified manner really only comes with a significant investment of time, direction, and capital. Due to the seriousness of Canonical's altruistic vision, as we generate this capital, we're making the dream come true for the world.

At AllHands, I've seen designs that will seriously challenge Apple. I've seen a usability team's plans for true computing goodness. I've seen revenue models that have made my jaw drop. I've seen glimpses of the bright future.

And baby, it's exciting as hell.

Newest Members of the PSF


Since it's now official, I can blog about it: I was delighted to discover that JP, radix, glyph, and I were voted into the Python Software Foundation this year at PyCon :-) Not only is that four for Twisted, but it's two for Divmod and two more for Canonical.

There was another Canonical employee -- Matthias Klose -- voted in as well, and with Barry Warsaw and Gustavo Niemeyer, that brings a tally for Canonical/Ubuntu to at least 5, and maybe more (let me know if I've missed you!).

It gets even better, though: check out the rest of the new members list:
  • Jim Baker
  • Ben Bangert
  • James Bennett
  • Graham Dumpleton
  • Martijn Faassen
  • Michael Fletcher
  • Michael Foord
  • Doug Hellmann
  • Adrian Holovaty
  • Jacob Kaplan-Moss
  • Jesse Noller
  • Benjamin Peterson
  • Ted Pollari
  • Mark Ramm
  • Malcolm Tredinnick
  • Kirby Urner
  • Robert Dino Viehland
  • Thomas Waldmann
  • Frank Wierzbicki
I am thrilled to be a PSF member and look forward to deepening my support of Python through this new level of involvement. Even more, though, I'm honored and delighted to be working with both the esteemed veteran members as well as these amazing new additions.

Ubuntu Developer Summit


For the past two weeks, I've been listening, learning, discussing, and hacking various Landscape and Ubuntu initiatives with members of the Ubuntu community and fellow Canonical employees. It was an amazing experience, and we've got the next 6 months crammed full of plans... with the next 3 months already spec'ed out.

Canonical has surprised me. It's an extraordinary company... both in the modern business-sense of the word as well as the original sense: a fellowship of companions with a common goal. While so far I have only had a chance to hear some personal histories, it's evident that every member of this company is an extraordinary individual with a rich background and a great deal to offer to the whole. Everyone works with an unprecedented amount of motivation towards the company vision, one that is well and tightly integrated into the corporate culture.

There is a bright future ahead for this amazing group...

Current and Future Happenings


Sorry there's been so much radio silence at this end lately... a lot has been going on, and it looks like it's going to stay that way for a while. I just need to get used to it and start posting again :-)

Canonical

The big news is that Canonical quite took me by surprise :-) I had planned on doing consulting work again, but I was made an offer of camaraderie, to come join a team at Canonical that I know well, and I couldn't resist. I'm now working on the Landscape team at Canonical, the same folks who brought you the much beloved Storm ORM :-)

Already, I've been working there for two weeks and it's been a delight. They use a lot of the same processes that we did at Divmod and in the Twisted project (in fact, three of us on the team are Twisted developers), so that was very smooth. Another thing that made the transition very easy was manner in which they engage in a beautiful mix of group discussion and rapid development. The open source community roots at Canonical are very deep... and you can see them very clearly without digging :-)

At Canonical, I've repeated run across old friends from my Zope days, from Hacking Society in Colorado, and other places/associations from my past. I am somewhat stunned at the job Canonical has done in acquiring a talented and dedicated workforce. I've never seen a company embrace open source at the level and to the degree that this company does, while at the same time retaining all of the most excellent qualities of the community within the corporate culture. Someone should do a socio-technological/business PhD thesis on these guys...

In preparation for the many (and intense) marathon sprints that this team runs in a year, I've purchased a new laptop. It's the first dedicated Ubuntu dev machine/Desktop I've had... I've been running all my Ubuntu instances as virtual machines in Parallels and VMWare Fusion (or as remote servers at colos and virtual host providers). My love for the Evolution mail client continues to grow and I've found the only reason I miss the Mac is for the automatic handling of sound and to play Spore :-) 

SOA Conference

Now on to some future stuff. I've been invited to speak about dynamic languages (Python) and ultra-large scale (ULS) systems at SOA-India this year in Bangalore. The industry that has grown up around service oriented architectures (SOA) overwhelmingly tends towards Java, so this is a really great sign. I think the efforts that the Java Mothership has made in building bridges with dynamic languages such as Ruby and Python is having a tremendous impact throughout the programming world. I've got an eye on Ted Leung and the Jython team :-)

Anyway, the conference promises to be quite interesting, with speakers from around the world and with diverse backgrounds. I'm expecting to return from Bangalore with a multitude of new ideas and lots of new avenues to explore.

Blog 

Speaking of SOA, I am still working on the second part of the book review for Josuttis' book SOA in Practice. Perhaps before I finish that one, though, I will blog about another O'Reilly title I have been enjoying immensely: Van Lindberg's  Intellectual Property and Open Source. Note that Van has been quite active in the Python community and is contributing his expertise at many levels for the benefit of us all. Regardless, the book is very well written and I will have nothing but good to say about it :-)

After that, I'm going to finish up the draft I have for a blog post on metaclasses, based on notes I took while working with Incredible Pear on the PBS DTV project.

And finally, there have been more requests for me to write about setting up a Twisted Mail server... so, as one reader puts it, I will conclude the telling of that tale in an up-coming post as well :-)

trac Stats Gathering with Storm

One of the things we've wanted to do recently at Divmod is track development status of milestones as well as gain some perspective on repository history/trends in activity. The first thing I did? Looked at SQL for about 2 and a half minutes. The second thing I did? Fired up a python instance and imported storm.locals :-)

With a few minutes of typing and looking stuff up (e.g., how to define compound keys for an already extant schema/db), I was up and running and was able to concentrate fully on the problem at hand (reports) and how to represent data visually (matplotlib). Now that's how an ORM is supposed to work :-)

Here are the schemas I defined in python:




Note the 1-to-m relationship of revision to nodes changed -- so easy :-)

This is exactly what a (good) tool is supposed to let you do: focus on and solve the larger problem at hand, not get lost fixing tools. With the schemas defined, the queries took literal seconds to write, I had my data, and was able to start generating textual summaries as well as processing the queries for graphs.

Wanna see some graphs? Below is a slide show of some graphs (just a few of the hundreds that are generated) representing the work of the Divmod dev team over various points in time on a secondary trac instance (not our main, Divmod trac instance). Though I haven't included them in the slide show, the code also generates graphs per-user, per-time-period.


Created with Admarket's flickrSLiDR.

Update: Thanks Nafai for poking me about the oversight of not giving shouts out for the graphing tool: matplotlib (of which I have been a huge fan of since I first heard about it years ago, having suffered through proprietary and kludgey Matlab as a physics student).

Ubuntu 7.04 on iMac Core 2 Duo, 2G

Well, I busted me arse this afternoon and evening trying to get Ubuntu set up on my new iMac. It installed without issue (using the "alternate" x386 iso), but has the following critical issues:
  1. No wireless
  2. No widescreen support
  3. No sound
  4. Doesn't recognize CD/DVD drive after install and reboot
I'm kind of bummed, since I'd planned on doing dev work on this box (can we even call the iMacs "boxes"?) in native Ubuntu, and now I'll have to use parallels until the driver support is developed. Or until someone sends me a link that I've managed to miss despite incessant googling today...

Once I'm moved into the new place, I'll have a GB switch in the office and will be able to work in Ubuntu over copper. The resolution bugs me more than the lack of sound and DVD, but I can live with those for now. I guess.

But, hey -- it plays WoW and UT2004 in OS X like a champ :-)
